We are one of the leading solar energy companies in the world as measured by production output in 2008, with leading positions in key solar markets. Since we commenced business operations in May 2002, we have grown rapidly to become the world’s third largest manufacturer of photovoltaic, or PV, cells in 2008, based on production output. We believe that we are a key player in the rapidly expanding solar power industry globally. We design, develop, manufacture and market a variety of PV cells and modules, including a broad range of value-added building-integrated photovoltaics, or BIPV, products. Our products are used to provide reliable and environmentally friendly electric power for residential, commercial, industrial and public utility applications in various markets worldwide. We also provide PV system integration services to customers in China and the United States, and are expanding into the development of utility scale solar power systems.

We sell our products in various key solar energy markets worldwide including Spain, Germany, the United States, China, South Korea, Italy, the Middle East, Australia and Japan. We currently sell our products primarily through a selected number of value-added resellers such as distributors and system integrators and to end users such as project developers that have particular expertise and experience in a given geographic or applications market. We have established local sales offices in our key markets such as Spain, Germany and the United States, and have also been actively establishing local sales offices in 2008 in markets we believe to have significant potential such as Australia, Japan and South Korea in the Asia Pacific, Italy and Switzerland in Europe, and the United Arab Emirates in the Middle East. We plan to continue to increase our direct sales activities in the United States, the Asia Pacific and the Middle East. We believe that our local sales offices will enhance our ability to localize customer service and support, which will help foster closer relationships with our key customers.

We believe that we have been able to grow rapidly because of our ability to capitalize on the PV market’s demand for high efficiency products at low cost per watt. Our strong research and development capabilities have enabled us to develop advanced process technologies and manufacture, cost-effectively and on a large scale, PV cells and modules with high conversion efficiencies. Conversion efficiency rates measure the ability of PV products to convert sunlight into electricity. As of December 31, 2008, the average conversion efficiency rates of our monocrystalline and multicrystalline silicon PV cells were 17.2% and 15.2%, respectively. In 2008, we commenced commercial production of PV cells utilizing Pluto technology, a high efficiency PV technology that allows us to achieve conversion efficiency rates in the range of 18.0% to 19.0% on PV cells manufactured with monocrystalline silicon wafers and 16.5% to 17.5% on PV cells manufactured with multicrystalline silicon wafers. We had achieved 30 MW of Pluto cell production capacity by December 31, 2008, and plan to accelerate retrofitting of existing production lines to Pluto technology in order to achieve 300 MW of Pluto cell production capacity by the end of 2009.

We believe our China-based design, development and manufacturing facilities provide us with several competitive advantages, including access to low-cost technical expertise, skilled labor and facilities. We leverage our cost advantages by optimizing the balance between automation and manual operations in our manufacturing processes, which we believe lowers our operating costs and capital expenditures and enables us to expand our manufacturing capacity in a cost-effective manner. We continuously evaluate and adjust our combination of automated and manual operations in our manufacturing processes in order to optimize our cost structure while improving our manufacturing yields and quality.

Our company

As of December 31, 2008, our annualized aggregate PV cell manufacturing capacity reached 1,000 MW per annum, increasing significantly from 10 MW in 2002, when we completed our first PV cell manufacturing line and from 540 MW as of December 31, 2007. In 2008, we began construction on our thin film buildings and supporting facilities at our Shanghai plant, which is scheduled for completion by the end of the second quarter of 2009. By completion, our Shanghai plant will be able to accommodate a maximum of six thin film production lines with each line having a production capacity of up to 50 MW for a total plant production capacity of up to 300 MW. In the second half of 2009, we target to finish the installation of the first of the six thin film production lines at our Shanghai plant and to begin the commercial manufacture of PV modules utilizing thin film technology with an initial annual production capacity of up to 50 MW. The other five thin film production lines will be scheduled for future installation based on market conditions.

Please see the factors set forth under the heading “Item 3. Key Information—D. Risk Factors” in our most recently filed annual report on Form 20-F, which is incorporated in this prospectus by reference, and, if applicable, in any accompanying prospectus supplement before investing in any securities that may be offered pursuant to this prospectus.

We intend to use the net proceeds from the sale of the securities as set forth in the applicable prospectus supplement.

We are incorporated in the Cayman Islands to take advantage of certain benefits associated with being an exempted Cayman Islands company, such as:

However, certain disadvantages accompany incorporation in the Cayman Islands. These disadvantages include:

Our constituent documents do not contain provisions requiring that disputes, including those arising under the securities laws of the United States, between us, our officers, directors and shareholders, be arbitrated. Substantially all of our current operations are conducted in China, and substantially all of our assets are located in China. A majority of our directors and officers are nationals or residents of jurisdictions other than the United States and a substantial portion of their assets are located outside the United States. As a result, it may be difficult for a shareholder to effect service of process within the United States upon us or such persons, or to enforce against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States.

Maples and Calder, our counsel as to Cayman Islands law, has advised that there is no statutory mechanism by which a judgment obtained in the United States courts can be recognized or enforced in the Cayman Islands. However, the courts of the Cayman Islands will recognize and enforce a judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given and would give a judgment based thereon, provided that such judgment is final and conclusive, for a liquidated sum, not in respect of taxes or a fine or penalty or similar charge, is not inconsistent with a Cayman Islands’ judgment in respect of the same matter, and was not obtained in a manner, and is not a kind the enforcement of which is, contrary to the public policy of the Cayman Islands.

However, there is uncertainty as to whether the courts of the Cayman Islands and the PRC, respectively, would:

A final and conclusive judgment in the federal or state courts of the United States under which a fixed or ascertained sum of money is payable, other than a sum payable in respect of taxes, fines, penalties or similar charges and which was neither obtained in a manner nor is of a kind enforcement of which is contrary to natural justice or the public policy of the Cayman Islands, may be subject to enforcement

Enforceability of civil liabilities

proceedings as a debt in the courts of the Cayman Islands under common law. The civil liability provisions of United States federal and state securities law generally permit punitive damages against us. It is uncertain whether a judgment obtained from a United States court under the civil liability provisions of United States federal or state securities laws would be regarded by Cayman Islands courts as penal or punitive in nature. Such a determination has yet to be made by any Cayman Islands court.

The recognition and enforcement of foreign judgments are provided for under the PRC Civil Procedures Law. PRC courts may recognize and enforce foreign judgments in accordance with the requirements of the PRC Civil Procedures Law based either on treaties between the PRC and the country where the judgment is made or on reciprocity between jurisdictions. If there are no treaties or reciprocity arrangements between the PRC and a foreign jurisdiction where a judgment is rendered, according to PRC Civil Procedures Law, matters relating to the recognition and enforcement of the foreign judgment in the PRC may be resolved through diplomatic channels. The PRC does not have any treaties or other arrangements with the United States or the Cayman Islands that provide for the reciprocal recognition and enforcement of foreign judgments. As a result, it is generally difficult to enforce in the PRC a judgment rendered by a United States or Cayman Islands court.

The following table sets forth our ratio of earnings to fixed charges on a historical basis for the period indicated. The ratio of earnings to fixed charge is computed by dividing earnings by fixed charges. For the purpose of computing the consolidated ratio of earnings to fixed charges, earnings consist of income from continuing operations before income taxes and equity in income (loss) of investees and minority interests, plus fixed charges, amortization of capitalized interest and distributed income of equity investees and losses before tax of equity investees for which charges arising from guarantees are included in fixed charges, minus capitalized interest and minority interest in pre-tax income of subsidiaries that have not incurred fixed charges. Fixed charges consist of interest expense, including capitalized interest, amortized premiums, discounts and capitalized expenses related to indebtedness and estimated interest included in rental expense.

We may issue from time to time, in one or more offerings, the following securities:

We will set forth in the applicable prospectus supplement a description of the preferred shares, debt securities and warrants, and, in certain cases, the ordinary shares (including ordinary shares represented by ADSs) that may be offered under this prospectus. The terms of the offering of securities, the initial offering price and the net proceeds to us will be contained in the prospectus supplement, and other offering material, relating to such offer. The supplement may also add, update or change information contained in this prospectus. You should carefully read this prospectus and any supplement before you invest in any of our securities.

We are a Cayman Islands exempted company with limited liability and our affairs are governed by our memorandum and articles of association, as amended and restated from time to time, and the Companies Law (2007 Revision) of the Cayman Islands, which is referred to as the Companies Law below.

As of the date hereof, our authorized share capital consists of 500,000,000 ordinary shares, with a par value of $0.01 each. As of December 31, 2008, there were 157,148,293 ordinary shares issued and outstanding, which included 1,267,761 ordinary shares issued in connection with and held for the purposes of the Company’s equity incentive plan.

In connection with entering into a supply agreement with one of our major suppliers of polysilicon and silicon wafers, on July 25, 2006, we granted this supplier a warrant to purchase 7,359,636 of our ordinary shares at $27.97 per share. The warrant is exercisable in five separate 20% annual increments, with the first 20% annual increment being exercisable commencing on January 1, 2008, and each additional 20% annual increment becomes exercisable on January 1, 2009, 2010, 2011 and 2012, respectively. The warrant holder has five years to exercise the exercisable portion of the warrant.

The following are summaries of material provisions of our second amended and restated memorandum and articles of association and the Companies Law insofar as they relate to the material terms of our ordinary shares.

ORDINARY SHARES

General

All of our outstanding ordinary shares are fully paid and non-assessable. Certificates representing the ordinary shares are issued in registered form. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their ordinary shares.

Dividends

The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors subject to the Companies Law.

Voting rights

Each ordinary share is entitled to one vote on all matters upon which the ordinary shares are entitled to vote. Voting at any meeting of shareholders is by show of hands unless a poll is demanded. A poll may be demanded by the chairman of our board of directors or by any shareholder present in person or by proxy.

A quorum required for a meeting of shareholders consists of shareholders who hold at least one-third of our ordinary shares at the meeting present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative. Shareholders’ meetings are held annually and may be convened by our board of directors on its own initiative or upon a request to the directors by shareholders holding in aggregate at least ten percent of our ordinary shares. Advance notice of at least seven days is required for the convening of our annual general meeting and other shareholders meetings.

An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast in a general meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the ordinary shares. A special resolution will be required for important matters such as a change of name or making changes to our second amended and restated memorandum and articles of association.

Description of share capital

Transfer of ordinary shares

Subject to the restrictions of our articles of association, as applicable, any of our shareholders may transfer all or any of his or her ordinary shares by an instrument of transfer in the usual or common form or any other form approved by our board.

Our board of directors may, in its absolute discretion, decline to register any transfer of any ordinary share which is not fully paid up or on which we have a lien. Our directors may also decline to register any transfer of any ordinary share unless:

If our directors refuse to register a transfer they shall, within two months after the date on which the instrument of transfer was lodged, send to each of the transferor and the transferee notice of such refusal. The registration of transfers may, on 14 days’ notice being given by advertisement in such one or more newspapers or by electronic means, be suspended and the register closed at such times and for such periods as our board of directors may from time to time determine, provided, however, that the registration of transfers shall not be suspended nor the register closed for more than 30 days in any year.

Liquidation

On a return of capital on winding up or otherwise (other than on conversion, redemption or purchase of ordinary shares), assets available for distribution among the holders of ordinary shares shall be distributed among the holders of the ordinary shares on a pro rata basis. If our assets available for distribution are insufficient to repay all of the paid-up capital, the assets will be distributed so that the losses are borne by our shareholders proportionately.

Calls on ordinary shares and forfeiture of ordinary shares

Our board of directors may from time to time make calls upon shareholders for any amounts unpaid on their ordinary shares in a notice served to such shareholders at least 14 days prior to the specified time of payment. The ordinary shares that have been called upon and remain unpaid are subject to forfeiture.

Redemption of ordinary shares

Subject to the provisions of the Companies Law, we may issue shares on terms that are subject to redemption, at our option or at the option of the holders, on such terms and in such manner as may be determined by our second amended and restated memorandum and articles of association.

Variations of rights of shares

All or any of the rights attached to any class of shares may, subject to the provisions of the Companies Law, be varied either with the unanimous written consent of the holders of the issued shares of that class or with the sanction of a resolution passed by at least two-thirds of the holders of shares of that class present in person or by proxy at a general meeting of the holders of the shares of that class.

Description of share capital

Inspection of books and records

Holders of our ordinary shares have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records (save that such holders shall be entitled to a copy of the memorandum and articles of association on payment of any applicable fee). However, we will provide our shareholders with annual audited financial statements.

Changes in capital

We may from time to time by ordinary resolutions:

We may by special resolution reduce our share capital and any capital redemption reserve in any manner authorized by law.

EXEMPTED COMPANY

We are an exempted company with limited liability under the Companies Law (2007 Revision) of the Cayman Islands. The Companies Law in the Cayman Islands distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

“Limited liability” means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company. We are subject to reporting and other informational

Description of share capital

requirements of the Exchange Act, as applicable to foreign private issuers. We currently comply with the NYSE Rules, in lieu of following home country practice after the closing of our initial public offering. The NYSE Rules require that every company listed on the New York Stock Exchange hold an annual general meeting of shareholders. In addition, our second amended and restated articles of association, which allow directors or shareholders to call special shareholder meetings pursuant to the procedures set forth in the articles.

DIFFERENCES IN CORPORATE LAW

The Companies Law is modeled after that of English law but does not follow many recent English law statutory enactments. In addition, the Companies Law differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of the significant differences between the provisions of the Companies Law applicable to us and the laws applicable to companies incorporated in the United States and their shareholders.

Mergers and similar arrangements

The Companies Law permits mergers and consolidations between Cayman Islands companies and between Cayman Islands companies and non-Cayman Islands companies. For these purposes, (a) “merger” means the merging of two or more constituent companies and the vesting of their undertaking, property and liabilities in one of such companies as the surviving company and (b) a “consolidation” means the combination of two or more constituent companies into a consolidated company and the vesting of the undertaking, property and liabilities of such companies to the consolidated company. In order to effect such a merger or consolidation, the directors of each constituent company must approve a written plan of merger or consolidation (a “Plan”), which must then be authorised by either (a) a special resolution of the shareholders of each constituent company voting together as one class if the shares to be issued to each shareholder in the consolidated or surviving company will have the same rights and economic value as the shares held in the relevant constituent company or (b) a shareholder resolution of each constituent company passed by a majority in number representing 75% in value of the shareholders voting together as one class. The Plan must be filed with the Registrar of Companies together with a declaration as to the solvency of the consolidated or surviving company, a list of the assets and liabilities of each constituent company and an undertaking that a copy of the certificate of merger or consolidation will be given to the members and creditors of each constituent company and published in the Cayman Islands Gazette. Dissenting shareholders have the right to be paid the fair value of their shares (which, if not agreed between the parties, will be determined by the Cayman Islands court) if they follow the required procedures, subject to certain exceptions. Court approval is not required for a merger or consolidation which is effected in compliance with these statutory procedures. In addition, there are statutory provisions that facilitate the reconstruction and amalgamation of companies, provided that the arrangement is approved by a majority in number of each class of shareholders and creditors with whom the arrangement is to be made, and who must in addition represent three-fourths in value of each such class of shareholders or creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meetings, convened for that purpose. The convening of the meetings and subsequently the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder has the right to express to the court the view that the transaction ought not to be approved, the court can be expected to approve the arrangement if it determines that:

Description of share capital

When a take-over offer is made and accepted by holders of 90.0% of the shares (within four months), the offerer may, within a two month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection can be made to the Grand Court of the Cayman Islands but this is unlikely to succeed unless there is evidence of fraud, bad faith or collusion.

If the arrangement and reconstruction is thus approved, the dissenting shareholder would have no rights comparable to appraisal rights, which would otherwise ordinarily be available to dissenting shareholders of United States corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

Shareholders’ suits

We are not aware of any reported class action or derivative action having been brought in a Cayman Islands court. In principle, we will normally be the proper plaintiff and a derivative action may not be brought by a minority shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority in the Cayman Islands, there are exceptions to the foregoing principle, including when:

Indemnification of directors and executive officers and limitation of liability

Cayman Islands law does not limit the extent to which a company’s articles of association may provide for indemnification of officers and directors, except to the extent any such provision may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Our second amended and restated memorandum and articles of association permit indemnification of officers and directors for losses, damages, liabilities, costs and expenses incurred in their capacities as such unless such losses or damages arise from dishonesty, fraud or default of such directors or officers. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we have entered into indemnification agreements with our directors and senior executive officers that provide such persons with additional indemnification beyond that provided in our second amended and restated memorandum and articles of association.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers or persons controlling us under the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable as a matter of United States law.

Anti-takeover provisions in the second amended and restated memorandum and articles of association

Some provisions of our second amended and restated memorandum and articles of association may discourage, delay or prevent a change in control of our company or management that shareholders may consider favorable, including provisions that authorize our board of directors to issue preference shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preference shares without any further vote or action by our shareholders.

Description of share capital

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our second amended and restated memorandum and articles of association, as amended and restated from time to time, for what they believe in good faith to be in the best interests of our company.

Directors’ fiduciary duties

Under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he reasonably believes to be in the best interests of the corporation. He must not use his corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company and therefore it is considered that he owes the following duties to the company—a duty to act bona fide in the best interests of the company, a duty not to make a profit based on his position as director (unless the company permits him to do so) and a duty not to put himself in a position where the interests of the company conflict with his personal interest or his duty to a third party. A director of a Cayman Islands company owes to the company a duty to act with skill and care. It was previously considered that a director need not exhibit in the performance of his duties a greater degree of skill than may reasonably be expected from a person of his knowledge and experience. However, English and Commonwealth courts have moved towards an objective standard with regard to the required skill and care and these authorities are likely to be followed in the Cayman Islands.

Shareholder action by written consent

Under the Delaware General Corporation Law, a corporation may eliminate the right of shareholders to act by written consent by amendment to its certificate of incorporation. Cayman Islands law and our second amended and restated articles of association provide that shareholders may approve corporate matters by way of a unanimous written resolution signed by or on behalf of each shareholder who would have been entitled to vote on such matter at a general meeting without a meeting being held.

Shareholder proposals

Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

Cayman Islands law and our second amended and restated articles of association allow our shareholders holding not less than 10 per cent of the paid up voting share capital of the Company to requisition a shareholder’s meeting. As an exempted Cayman Islands company, we are not obliged by law to call

shareholders’ annual general meetings. However, our second amended and restated articles of association require us to call such meetings.

Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation’s certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder’s voting power with respect to electing such director. As permitted under Cayman Islands law, our second amended and restated articles of association do not provide for cumulative voting. As a result, our shareholders are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

Removal of directors

Under the Delaware General Corporation Law, a director of a corporation with a classified board may be removed only for cause with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. Under our second amended and restated articles of association, directors can be removed, but only by the vote of holders of two-thirds of our shares, cast at a general meeting, or the unanimous written resolution of all shareholders, or upon written notice by the shareholder who nominated such director any time for any reason.

Transactions with interested shareholders

The Delaware General Corporation Law contains a business combination statute applicable to Delaware public corporations whereby, unless the corporation has specifically elected not to be governed by such statute by amendment to its certificate of incorporation, it is prohibited from engaging in certain business combinations with an “interested shareholder” for three years following the date that such person becomes an interested shareholder. An interested shareholder generally is a person or group who or which owns or owned 15% or more of the target’s outstanding voting stock within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which such shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware public corporation to negotiate the terms of any acquisition transaction with the target’s board of directors.

Cayman Islands law has no comparable statute. As a result, we cannot avail ourselves of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that such transactions must be entered into bona fide in the best interests of the company and not with the effect of constituting a fraud on the minority shareholders.

Dissolution; winding up

Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. Only if the dissolution is initiated by the board of directors may it be approved by a simple majority of the corporation’s outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board. Under the Companies Law of the Cayman Islands and our second amended and restated articles of association, our company may be dissolved, liquidated or wound up by

the vote of holders of two-thirds of our shares voting at a meeting or the unanimous written resolution of all shareholders.

Variation of rights of shares

Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of such class, unless the certificate of incorporation provides otherwise. Under Cayman Islands law and our second amended and restated articles of association, if our share capital is divided into more than one class of shares, we may vary the rights attached to any class only with the sanction of a resolution passed by at least two-thirds of the holders of shares of that class present in person or by proxy at a general meeting of the holders of the shares of that class or unanimous written consent of the holders of the shares of that class.

Amendment of governing documents

Under the Delaware General Corporation Law, a corporation’s governing documents may be amended with the approval of a majority of the outstanding shares entitled to vote, unless the certificate of incorporation provides otherwise. As permitted by Cayman Islands law, our second amended and restated memorandum and articles of association may only be amended with the vote of holders of two-thirds of our shares voting at a meeting or the unanimous written resolution of all shareholders.

Rights of non-resident or foreign shareholders

There are no limitations imposed by our second amended and restated memorandum and articles of association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on our shares. In addition, there are no provisions in our second amended and restated memorandum and articles of association governing the ownership threshold above which shareholder ownership must be disclosed.

AMERICAN DEPOSITARY RECEIPTS

The Bank of New York Mellon (formerly known as The Bank of New York), as depositary, will execute and deliver ADRs. ADRs are American depositary receipts. Each ADR is a certificate evidencing a specific number of American depositary shares, also referred to as ADSs. Each ADS represents one ordinary share (or a right to receive one ordinary share) deposited with the principal Hong Kong office of The Hong Kong and Shanghai Banking Corporation Limited, as custodian for the depositary in Hong Kong. Each ADS will also represent any other securities, cash or other property which may be held by the depositary under the deposit agreement referred to below. The depositary’s corporate trust office at which the ADRs are administered is located at 101 Barclay Street, New York, New York 10286. The Bank of New York Mellon’s principal executive office is located at One Wall Street, New York, New York 10286.

You may hold ADSs either directly (by having an ADR registered in your name) or indirectly through your broker or other financial institution. If you hold ADSs directly, you are an ADR holder. This description assumes you hold your ADSs directly. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADR holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

We will not treat our ADS holders as one of our shareholders and you will not have shareholder rights. Cayman Islands law governs shareholder rights. The depositary will be the holder of the shares underlying your ADSs. As a holder of ADRs, you will have ADR holder rights. A deposit agreement among us, the depositary and you, as an ADR holder, and the beneficial owners of ADRs set out ADR holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADRs.

The following is a summary of the material provisions of the deposit agreement. For more complete information, you should read the entire deposit agreement and the form of ADR attached thereto.

DIVIDENDS AND OTHER DISTRIBUTIONS

How will you receive dividends and other distributions on the shares?

The depositary has agreed to pay to you the cash dividends or other distributions it or the custodian receives on shares or other deposited securities, after deducting its fees and expenses. You will receive these distributions in proportion to the number of shares your ADSs represent.

Description of American depositary shares

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADR holders. We have no obligation to register ADSs, shares, rights or other securities under the Securities Act. We also have no obligation to take any other action to permit the distribution of ADSs, shares, rights or anything else to ADR holders. This means that you may not receive the distributions we make on our shares or any value for them if it is illegal or impractical for us to make them available to you.

DEPOSIT AND WITHDRAWAL

How are ADSs issued?

The depositary will deliver ADSs if you or your broker deposits shares or evidence of rights to receive shares with the custodian. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will register the appropriate number of ADSs in the names you request and will deliver the ADRs at its corporate trust office to the persons you request.

How do ADS holders cancel an ADR and obtain shares?

You may surrender your ADRs at the depositary’s office. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will deliver the shares and any other deposited securities underlying the ADR to you or a person you designate at the office of the custodian. Or, at your request, risk and expense, the depositary will deliver the deposited securities at its corporate trust office, if feasible.

VOTING RIGHTS

How do you vote?

You may instruct the depositary to vote the number of shares your ADSs represent. The depositary will notify you of shareholders’ meetings and arrange to deliver our voting materials to you if we ask it to and we will notify the depositary no less than 30 days before the meeting date. Those materials will describe the matters to be voted on and explain how you may instruct the depositary how to vote. For instructions to be valid, they must reach the depositary by a date set by the depositary.

The depositary will try, in so far as practical, subject to the Cayman Islands law and the provisions of our constitutive documents, to vote the number of shares or other deposited securities represented by your ADSs as you instruct. The depositary will only vote or attempt to vote as you instruct.

We cannot ensure that you will receive voting materials or otherwise learn of an upcoming shareholders’ meeting in time to ensure that you can instruct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to vote and there may be nothing you can do if your shares are not voted as you requested.

FEES AND EXPENSES

Description of American depositary shares

PAYMENT OF TAXES

The depositary may deduct the amount of any taxes owed from any payments to you. It may also sell deposited securities, by public or private sale, to pay any taxes owed. You will remain liable if the proceeds of the sale are not enough to pay the taxes. If the depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to reflect the sale and pay to you any proceeds, or send to you any property, remaining after it has paid the taxes.

RECLASSIFICATIONS, RECAPITALIZATIONS AND MERGERS

AMENDMENT AND TERMINATION

How may the deposit agreement be amended?

We may agree with the depositary to amend the deposit agreement and the ADRs without your consent for any reason. If an amendment adds or increases fees or charges (except for taxes and other governmental charges or expenses of the depositary for registration fees, facsimile costs, delivery charges or similar items) or prejudices a substantial right of ADR holders, it will not become effective for outstanding ADRs until 30 days after the depositary notifies ADR holders of the amendment. At the time an amendment becomes effective, you are considered, by continuing to hold your ADR, to agree to the amendment and to be bound by the ADRs and the deposit agreement as amended.

Description of American depositary shares

How may the deposit agreement be terminated?

The depositary will terminate the deposit agreement if we ask it to do so, by notifying you at least 30 days before termination. The depositary may also terminate the deposit agreement if the depositary has told us that it would like to resign and we have not appointed a new depositary bank within 60 days. In either case, the depositary must notify you at least 30 days before termination.

After termination, the depositary and its agents will do the following under the deposit agreement but nothing else: (1) advise you that the deposit agreement is terminated, (2) collect distributions on the deposited securities, (3) sell rights and other property, and (4) deliver shares and other deposited securities upon cancellation of ADRs. Six months or more after termination, the depositary may sell any remaining deposited securities by public or private sale. After that, the depositary will hold the money it received on the sale, as well as any other cash it is holding under the deposit agreement for the pro rata benefit of the ADR holders that have not surrendered their ADRs. It will not invest the money and has no liability for interest. The depositary’s only obligations will be to account for the money and other cash. After termination our only obligations will be to indemnify the depositary and to pay fees and expenses of the depositary that we agreed to pay.

LIMITATIONS ON OBLIGATIONS AND LIABILITY

Limits on our obligations and the obligations of the depositary; limits on liability to holders of ADRs

The deposit agreement expressly limits our obligations and the obligations of the depositary. It also limits our liability and the liability of the depositary. We and the depositary:

In the deposit agreement, we and the depositary agree to indemnify each other under certain circumstances.

In addition, the depositary is not liable for:

Requirements for depositary actions

Before the depositary will deliver or register a transfer of an ADR, make a distribution on an ADR, or permit withdrawal of shares or other property, the depositary may require:

Description of American depositary shares

The depositary may refuse to deliver ADRs or register transfers of ADRs generally when the transfer books of the depositary or our transfer books are closed or at any time if the depositary thinks or we think that it is advisable to do so.

Your right to receive the shares underlying your ADRs

You have the right to cancel your ADRs and withdraw the underlying shares at any time except:

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Pre-release of ADRs

The deposit agreement permits the depositary to deliver ADRs before deposit of the underlying shares. This is called a pre-release of the ADRs. The depositary may also deliver shares upon cancellation of pre-released ADRs (even if the ADRs are canceled before the pre-release transaction has been closed out). A pre-release is closed out as soon as the underlying shares are delivered to the depositary. The depositary may receive ADRs instead of shares to close out a pre-release. The depositary may pre-release ADRs only under the following conditions:

In addition, the number of shares not deposited but represented by ADSs outstanding at any time as a result of pre-release will not normally exceed 30% of the shares deposited, although the depositary may disregard the limit from time to time, if it thinks it is appropriate to do so.

We may sell or distribute the securities offered by this prospectus, from time to time, in one or more offerings, as follows:

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. In some cases, we or dealers acting for us or on our behalf may also repurchase securities and reoffer them to the public by one or more of the methods described above. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

Our securities distributed by any of these methods may be sold to the public, in one or more transactions, either:

SALE THROUGH UNDERWRITERS OR DEALERS

If underwriters are used in the sale, the underwriters will acquire the securities for their own account, including through underwriting, purchase, security lending or repurchase agreements with us. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions. Underwriters may sell the securities in order to facilitate transactions in any of our other securities (described in this prospectus or otherwise), including other public or private transactions and short sales. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless otherwise indicated in the applicable prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If dealers are used in the sale of securities offered through this prospectus, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The applicable prospectus supplement will include the names of the dealers and the terms of the transaction.

DIRECT SALES AND SALES THROUGH AGENTS

We may sell the securities offered through this prospectus directly. In this case, no underwriters or agents would be involved. Such securities may also be sold through agents designated from time to time. The applicable prospectus supplement will name any agent involved in the offer or sale of the offered securities and will describe any commissions payable to the agent. Unless otherwise indicated in the applicable prospectus supplement, any agent will agree to use its commercially reasonable efforts to solicit purchases for the period of its appointment.

Plan of distribution

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. The terms of any such sales will be described in the applicable prospectus supplement.

DELAYED DELIVERY CONTRACTS

If the applicable prospectus supplement indicates, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

MARKET MAKING, STABILIZATION AND OTHER TRANSACTIONS

Unless the applicable prospectus supplement states otherwise, each series of offered securities will be a new issue and will have no established trading market. We may elect to list any series of offered securities on an exchange. Any underwriters that we use in the sale of offered securities may make a market in such securities, but may discontinue such market making at any time without notice. Therefore, we cannot assure you that the securities will have a liquid trading market.

Any underwriter may also engage in stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Rule 104 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Stabilizing transactions involve bids to purchase the underlying security in the open market for the purpose of pegging, fixing or maintaining the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions.

Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions. Stabilizing transactions, syndicate covering transactions and penalty bids may cause the price of the securities to be higher than it would be in the absence of the transactions. The underwriters may, if they commence these transactions, discontinue them at any time.

DERIVATIVE TRANSACTIONS AND HEDGING

We and the underwriters may engage in derivative transactions involving the securities. These derivatives may consist of short sale transactions and other hedging activities. The underwriters may acquire a long or short position in the securities, hold or resell securities acquired and purchase options or futures on the securities and other derivative instruments with returns linked to or related to changes in the price of the securities. In order to facilitate these derivative transactions, we may enter into security lending or repurchase agreements with the underwriters. The underwriters may effect the derivative transactions through sales of the securities to the public, including short sales, or by lending the securities in order to facilitate short sale transactions by others. The underwriters may also use the securities purchased or borrowed from us or others (or, in the case of derivatives, securities received from us in settlement of those derivatives) to directly or indirectly settle sales of the securities or close out any related open borrowings of the securities.

LOANS OF SECURITIES

We or a selling shareholder may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus and an applicable prospectus supplement.
