DESCRIPTION OF SHARE CAPITAL

        We are a Cayman Islands exempted company with limited liability and our affairs are governed by our amended and restated memorandum and articles of association, the Companies Act (2021 Revision) of the Cayman Islands, which is referred to as the Companies Act below, and the common law of the Cayman Islands.

        As of the date of this prospectus, our authorized share capital is US$50,000 consisting of 500,000,000 ordinary shares with par value of US$0.0001 each. As of the date of this prospectus, we have 52,458,550 ordinary shares outstanding.

Our Memorandum and Articles of Association

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

        General    All of our issued and outstanding ordinary shares are fully paid and non-assessable. Our ordinary shares are issued in registered form, and are issued when registered in our register of members. Our shareholders who are non-residents of the Cayman Islands may freely hold and vote their ordinary shares. Under our amended and restated memorandum and articles of association, our company may issue only non-negotiable shares and may not issue bearer shares.

        Dividends    The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors. In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our directors. Under Cayman Islands law, our company may declare and pay a dividend only out of funds legally available therefor, namely out of either profit or our share premium account, provided that in no circumstances may we pay a dividend if this would result in our company being unable to pay its debts as they fall due in the ordinary course of business.

        Voting Rights    Holders of our ordinary shares vote as a single class on all matters submitted to a vote of our shareholders, except as may otherwise be required by law. In respect of matters requiring shareholders' vote, on a poll each ordinary share is entitled to one vote. At any general meeting a resolution put to the vote of the meeting shall be decided by a show of hands unless a poll is demanded. A poll may be demanded by the chairman of such meeting or any one or more shareholders who together hold not less than 10% of the paid up voting share capital.

        An ordinary resolution to be passed by the shareholders requires the affirmative vote of a simple majority of the votes attached to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes attached to the ordinary shares cast by those shareholders entitled to vote who are present in person or by proxy at a general meeting. A special resolution is required for important matters such as a change of name or any amendment to our memorandum and articles of association. Both ordinary resolution and special resolution may also be passed by a unanimous written resolution signed by all the shareholders of our company, as permitted by the Companies Act and our amended and restated memorandum and articles of association.

        General Meetings of Shareholders and Shareholder Proposals    As a Cayman Islands exempted company, we are not obliged by the Companies Act to call shareholders' annual general meetings. Our amended and restated memorandum and articles of association provide that we may, but are not obliged to, in each year hold a general meeting as our annual general meeting in which case we shall specify the meeting as such in the notices calling it, and the annual general meeting shall be held at such time and place as may be determined by our directors.

18

Table of Contents

        Shareholders' annual general meetings and any other general meetings of our shareholders may be convened by a majority of our board of directors or the chairman of the board. Advance notice of at least ten calendar days is required for the convening of our annual general shareholders' meeting and any other general meeting of our shareholders. A quorum required for a general meeting of shareholders consists of one or more shareholders present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative, who hold in aggregate not less than one-third of the votes attaching to all issued and outstanding shares of our company entitled to vote at general meetings.

        Cayman Islands law provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company's articles of association. Our amended and restated memorandum and articles of association allow any two or more of our shareholders holding in the aggregate not less than one-third of the votes attaching to the issued and outstanding shares of our company entitled to vote at general meetings, to requisition an extraordinary general meeting of the shareholders, in which case our directors are obliged to call such meeting and to put the resolutions so requisitioned to a vote at such meeting; however, our amended and restated memorandum and articles of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders.

        Transfer of Shares    Subject to the restrictions of our amended and restated memorandum and articles of association set out below, 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 ordinary form or any other form approved by our board of directors.

        Our board of directors may, in its sole discretion, decline to register any transfer of any ordinary share which is not fully paid up. Our directors may also decline to register any transfer of any ordinary share unless (a) the instrument of transfer is lodged with us, accompanied by the certificate for the ordinary shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer; (b) the instrument of transfer is properly stamped, if required; (c) in the case of a transfer to joint holders, the number of joint holders to whom the ordinary share is to be transferred does not exceed four; (d) the share to be transferred is free of any lien in favor of us; (e) a fee of such maximum sum as NASDAQ may determine to be payable, or such lesser sum as our board of directors may from time to time require, is paid to us in respect thereof; and (f) the instrument of transfer is in respect of only one class of shares.

        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, after compliance with any notice required of NASDAQ, be suspended and our register of members 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 of members closed for more than 30 days in any year as our board of directors may determine.

        Liquidation    On a winding up of our company, if the assets available for distribution among our shareholders shall be more than sufficient to repay the whole of the share capital at the commencement of the winding up, the surplus shall be distributed among our shareholders on a pro rata basis in proportion to the par value of the shares held by them at the commencement of the winding up, subject to a deduction from those shares in respect of which there are monies due, of all monies payable to our company for unpaid calls or otherwise. 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 in proportion to the par value of the shares held by them.

19

Table of Contents

        The liquidator may, with the sanction of a special resolution of our shareholders, divide amongst the shareholders in species or in kind the whole or any part of the assets of our company, and may for that purpose value any assets and determine how the division shall be carried out as between our shareholders or different classes of shareholders.

        We are a "limited liability" company registered under the Companies Act, and under the Companies Act, the liability of our members is limited to the amount, if any, unpaid on the shares respectively held by them. Our memorandum of association contains a declaration that the liability of our members is so limited.

        Calls on Shares and Forfeiture of 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 and place of payment. The ordinary shares that have been called upon and remain unpaid on the specified time are subject to forfeiture.

        Redemption, Repurchase and Surrender of Shares    We may issue shares on terms that such shares 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 board of directors, before the issue of such shares, or by a special resolution of our shareholders. Our company may also repurchase any of our shares provided that the manner and terms of such purchase have been approved by our board of directors or by ordinary resolution of our shareholders, or are otherwise authorized by our memorandum and articles of association. Under the Companies Act, the redemption or repurchase of any share may be paid out of our company's profits or out of the proceeds of a fresh issue of shares made for the purpose of such redemption or repurchase, or out of capital (including share premium account and capital redemption reserve) if the company can, immediately following such payment, pay its debts as they fall due in the ordinary course of business. In addition, under the Companies Act no such share may be redeemed or repurchased (a) unless it is fully paid up, (b) if such redemption or repurchase would result in there being no shares outstanding, or (c) if the company has commenced liquidation. In addition, our company may accept the surrender of any fully paid share for no consideration.

        Variations of Rights of Shares    If at any time, our share capital is divided into different classes of shares, all or any of the special rights attached to any class of shares may be varied either with the written consent of the holders of two-thirds in nominal value of the issued shares of that class, or with the sanction of a special resolution passed at a general meeting of the holders of shares of that class. The rights conferred upon the holders of the shares of any class issued with preferred or other rights will not, unless otherwise expressly provided by the terms of issue of the shares of that class, be deemed to be varied by the creation or issue of further shares ranking pari passu with such existing class of shares.

        Inspection of Books and Records    Holders of our ordinary shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records (other than our memorandum and articles of association, register of mortgages and charges, and copies of special resolutions passed by our shareholders). However, at the discretion of our board of directors, we intend to provide our shareholders with annual audited financial statements. See "Where You Can Find Additional Information.

        Changes in Capital    Our shareholders may from time to time by ordinary resolution:

•

increase our share capital by such sum, to be divided into shares of such classes and amount, as the resolution shall prescribe;



•

consolidate and divide all or any of our share capital into shares of a larger amount than our existing shares

20

Table of Contents

•

sub-divide our existing shares, or any of them into shares of a smaller amount, provided that in the subdivision the proportion between the amount paid and the amount, if any, unpaid on each reduced share shall be the same as it was in case of the share from which the reduced share is derived; or



•

cancel any shares that, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of our share capital by the amount of the shares so cancelled.

        Our shareholders may, by special resolution and subject to confirmation by the Grand Court of the Cayman Islands on an application by our company for an order confirming such reduction, reduce our share capital and any capital redemption reserve in any manner authorized by law.

        Issuance of Additional Shares    Our amended and restated memorandum and articles of association authorizes our board of directors to issue additional ordinary shares from time to time as our board of directors shall determine, to the extent there are available authorized but unissued shares.

        Our amended and restated memorandum and articles of association authorizes our board of directors to establish from time to time one or more series of convertible redeemable preferred shares and to determine, with respect to any series of convertible redeemable preferred shares, the terms and rights of that series, including:

•

designation of the series;



•

the number of shares of the series;



•

the dividend rights, conversion rights and voting rights; and



•

the rights and terms of redemption and liquidation preferences.

        The issuance of convertible redeemable preferred shares may be used as an anti-takeover device without further action on the part of the shareholders. Issuance of these shares may dilute the voting power of holders of ordinary shares.

        Anti-Takeover Provisions    Some provisions of our amended and restated memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable, including provisions that:

•

authorize our board of directors to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our shareholders; and



•

limit the ability of shareholders to requisition and convene general meetings of shareholders.

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

        Exempted Company    We are an exempted company with limited liability under the Companies Act. The Companies Act 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 that an exempted company:

•

does not have to file an annual return of its shareholders with the Registrar of Companies;



•

is not required to open its register of members for inspection;



•

does not have to hold an annual general meeting;

21

Table of Contents

•

may issue negotiable or bearer shares or shares with no par value;



•

may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);



•

may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;



•

may register as a limited duration company; and



•

may register as a segregated portfolio company.

        Limited liability" means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil). Our amended and restated memorandum and articles of association contains a declaration that the liability of our members is so limited.

        Register of Members    Under the Companies Act, we must keep a register of members and there should be entered therein:

•

the names and addresses of our members, a statement of the shares held by each member, and of the amount paid or agreed to be considered as paid, on the shares of each member, whether each class of shares held by a member carries voting rights under our articles of association, and if so, whether such voting rights are conditional;



•

the date on which the name of any person was entered on the register as a member; and



•

the date on which any person ceased to be a member.

        Under Cayman Islands law, the register of members of our company is prima facie evidence of the matters set out therein (i.e. the register of members will raise a presumption of fact on the matters referred to above unless rebutted) and a member registered in the register of members is deemed as a matter of Cayman Islands law to have legal title to the shares as set against its name in the register of members. Upon the completion of this offering, our company's register of members will be immediately updated to record and give effect to the issue of ordinary shares by us to the custodian (or its nominee) as the custodian. Once our register of members has been updated, the shareholders recorded in the register of members will be deemed to have legal title to the shares set against their name in the register of members.

        If the name of any person is incorrectly entered in or omitted from our register of members, or if there is any default or unnecessary delay in entering on the register the fact of any person having ceased to be a member of our company, the person or member aggrieved (or any member of our company or our company itself) may apply to the Grand Court of the Cayman Islands for an order that the register be rectified, and the Court may either refuse such application or it may, if satisfied of the justice of the case, make an order for the rectification of the register.

Differences in Corporate Law

        The Companies Act is derived, to a large extent, from the older Companies Acts of England, but does not follow recent United Kingdom statutory enactments, and accordingly there are significant differences between the Companies Act and the current Companies Act of England. In addition, the Companies Act differs from laws applicable to United States corporations and their shareholders. Set forth below is a summary of certain significant differences between the provisions of the Companies Act applicable to us and the comparable provisions of the laws applicable to companies incorporated in the State of Delaware and their shareholders.

Table of Contents

        Mergers and Similar Arrangements    The Companies Act 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, which must then be authorized by (i) a special resolution of the shareholders of each constituent company and (ii) such other authorization, if any, as may be specified in such constituent company's articles of association. The written plan of merger or consolidation 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 that notification of the merger will be published in the Cayman Islands Gazette. Court approval is not required for a merger or consolidation effected in compliance with these statutory procedures.

        A merger between a Cayman parent company and its Cayman subsidiary or subsidiaries does not require authorization by a resolution of shareholders of that Cayman subsidiary if a copy of the plan of merger is given to every member of that Cayman subsidiary to be merged unless that member agrees otherwise. For this purpose a company is a "parent" of a subsidiary if it holds issued shares that together represent at least 90% of the votes at a general meeting of the subsidiary.

        The consent of each holder of a fixed or floating security interest over a constituent company is required unless this requirement is waived by a court in the Cayman Islands.

        Save in certain limited circumstances, a shareholder of a Cayman constituent company who dissents from the merger or consolidation is entitled to payment of the fair value of his shares (which, if not agreed between the parties, will be determined by the Cayman Islands court) upon dissenting to the merger or consolidation, provided that the dissenting shareholder complies strictly with the procedures set out in the Companies Act. The exercise of dissenter rights will preclude the exercise by the dissenting shareholder of any other rights to which he or she might otherwise be entitled by virtue of holding shares, save for the right to seek relief on the grounds that the merger or consolidation is void or unlawful.

        Separate from the statutory provisions relating to mergers and consolidations, the Companies Act also contains 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:

•

the statutory provisions as to the required majority vote have been met;



•

the shareholders have been fairly represented at the meeting in question and the statutory majority are acting bona fide without coercion of the minority to promote interests adverse to those of the class;



•

the arrangement is such that may be reasonably approved by an intelligent and honest man of that class acting in respect of his interest; and

23

Table of Contents

•

the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Act.

        The Companies Act also contains a statutory power of compulsory acquisition which may facilitate the "squeeze out" of dissentient minority shareholder upon a tender offer. When a take-over offer is made and accepted by holders of 90.0% of the shares affected (within four months after the offer), the offeror may, within a two-month period commencing on the expiration of such four months 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 in the case of an offer which has been so approved unless there is evidence of fraud, bad faith or collusion.

        If an 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 Delaware corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

        Shareholders' Suits    In principle, we will normally be the proper plaintiff to sue for a wrong done to us as a company, and as a general rule 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, the Cayman Islands courts can be expected to apply and follow common law principles (namely the rule in Foss v Harbottle and the expectations thereto) that a non-controlling shareholder may be permitted to commence a class action against the company or a derivative action in the name of the company to challenge certain acts, including the following:

•

an act which is ultra vires or illegal and is therefore incapable of ratification by the shareholders;



•

an act which, although not ultra vires, could only be effected if duly authorized by a resolution with a qualified or special majority (i.e., more than a simple majority) that has not been obtained; and



•

an act which constitutes a "fraud on the minority" where the wrongdoers are themselves in control of the company.

        Indemnification of Directors and Executive Officers and Limitation of Liability    Cayman Islands law does not limit the extent to which a company's memorandum and 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 amended and restated memorandum and articles of association provide that our directors and officers shall be indemnified and secured harmless against all actions, proceedings, costs, charges, expenses, losses, damages or liabilities incurred or sustained by such director or officer, other than by reason of such person's own dishonesty, willful default or fraud, in or about the conduct of our company's business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such director or officer in defending (whether successfully or otherwise) any civil proceedings concerning our company or its affairs in any court whether in the Cayman Islands or elsewhere. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation. In addition, we intend to enter into indemnification agreements with our directors and senior executive officers that will provide such persons with additional indemnification beyond that provided in our 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,

24

Table of Contents

in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

        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 or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her 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 or her position as director (unless the company permits him to do so), a duty not to put himself in a position where the interests of the company conflict with his or her personal interest or his or her duty to a third party and a duty to exercise powers for the purpose for which such powers were intended. 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 or her duties a greater degree of skill than may reasonably be expected from a person of his or her 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. As permitted by Cayman Islands law, our amended and restated memorandum and articles of association provide that our 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 provides shareholders with only limited rights to requisition a general meeting, and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company's articles of association. Our amended and restated memorandum and articles of association allow any two or more of our shareholders holding in the aggregate not less than one-third of the votes attaching to all issued and outstanding shares of our company entitled to vote at general meetings to requisition an extraordinary meeting of the shareholders, in which case the directors are obliged to call such meeting and to put the resolutions so requisitioned to a vote at such meeting. However, our amended and restated memorandum and articles

25

Table of Contents

of association do not provide our shareholders with any right to put any proposals before annual general meetings or extraordinary general meetings not called by such shareholders.

        As an exempted Cayman Islands company, we are not obliged by law to call shareholders' annual general meetings. Our amended and restated memorandum and articles of association provides that we may in each year to hold a general meeting as our annual general meeting, and to specify the meeting as such in the notice calling it.

        Cumulative Voting    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. There are no prohibitions in relation to cumulative voting under Cayman Islands law, but our amended and restated memorandum and 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 of directors 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 amended and restated memorandum and articles of association, directors may be removed by ordinary resolution of our shareholders.

        Transactions with Interested Shareholders    The Delaware General Corporation Law contains a business combination statute applicable to Delaware 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 a 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 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, for a proper corporate purpose 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 of directors. Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company is unable to pay its debts as they fall due, by an

26

Table of Contents

ordinary resolution of its members. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

        Under the Companies Act of the Cayman Islands, our company may be dissolved, liquidated or wound up voluntarily by a special resolution, or by an ordinary resolution on the basis that we are unable to pay our debts as they fall due.

        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 our amended and restated memorandum and articles of association, and as permitted by Cayman Islands law, if our share capital is divided into more than one class of shares, we may vary the rights attached to any class either with the written consent of the holders of two-thirds in nominal value of the issued shares of that class or with the sanction of a special resolution passed at a general meeting 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. Under Cayman Islands law, our amended and restated memorandum and articles of association may only be amended by special resolution of our shareholders.

        Inspection of Books and Records    Under the Delaware General Corporation Law, any shareholder of a corporation may for any proper purpose inspect or make copies of the corporation's stock ledger, list of shareholders and other books and records.

        Holders of our shares will have no general right under Cayman Islands law to inspect or obtain copies of our list of shareholders or our corporate records (other than our memorandum and articles of association, register of mortgages and charges, and copies of special resolutions passed by our shareholders). However, we intend to provide our shareholders with annual reports containing audited financial statements.

        Anti-takeover Provisions in Our Memorandum and Articles of Association    Some provisions of our amended and restated memorandum and articles of association may discourage, delay or prevent a change of control of our company or management that shareholders may consider favorable, including a provision that authorizes 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.

        Such 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 decides to issue these preference shares, the price of our ADSs may fall and the voting and other rights of the holders of our ordinary shares underlying the ADSs may be materially and adversely affected.

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

        Rights of Non-resident or Foreign Shareholders    There are no limitations imposed by our 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.

DESCRIPTION OF AMERICAN DEPOSITARY SHARES

American depositary shares

        The name of the depositary is Citibank, N.A. The depositary's office is located at 388 Greenwich Street, 23rd Floor, New York, New York 10013 USA. American Depositary Shares are frequently referred to as "ADSs" and represent ownership interests in securities that are on deposit with the depositary bank. ADSs may be represented by certificates that are commonly known as "American Depositary Receipts" or "ADRs." The depositary bank typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is Citibank, N.A.—Hong Kong, located at 9/F, Citi Tower, One Bay East, 83 Hoi Bun Road, Kwun Tong, Kowloon, Hong Kong.

        Each ADS represents the right to receive and to exercise the beneficial ownership interests in three ordinary shares that are on deposit with the depositary bank and/or custodian. An ADS also represents the right to receive, and to exercise the beneficial interests in, any other property received by the depositary bank or the custodian on behalf of the owner of the ADS but that has not been distributed to the owners of ADSs because of legal restrictions or practical considerations.

        If you become an owner of ADSs, you will become a party to the deposit agreement and therefore will be bound by its terms and to the terms of any ADR that represents your ADSs. The deposit agreement and the ADR specify our rights and obligations as well as your rights and obligations as owner of ADSs and those of the depositary bank. As an ADS holder you appoint the depositary bank to act on your behalf in certain circumstances. The deposit agreement and the ADRs are governed by New York law. However, our obligations to the holders of the ordinary shares will continue to be governed by the laws of the Cayman Islands, which may be different from the laws of the United States.

        In addition, applicable laws and regulations may require you to satisfy reporting requirements and obtain regulatory approvals in certain circumstances. You are solely responsible for complying with such reporting requirements and obtaining such approvals. Neither the depositary bank, the custodian, us, or any of their or our respective agents or affiliates shall be required to take any actions whatsoever on your behalf to satisfy such reporting requirements or obtain such regulatory approvals under applicable laws and regulations.

        We will not treat ADS holders as our shareholders and accordingly, you, as an ADS holder, will not have shareholder rights. The depositary bank will hold on your behalf the shareholder rights attached to the ordinary shares underlying your ADSs. As an owner of ADSs, you will be able to exercise the shareholder rights for the ordinary shares represented by your ADSs through the depositary bank only to the extent contemplated in the deposit agreement. To exercise any shareholder rights not contemplated in the deposit agreement you will, as an ADS owner, need to arrange for the cancellation of your ADSs and become a direct shareholder.

        The registration of the ordinary shares in the name of the depositary bank or the custodian shall, to the maximum extent permitted by applicable law, vest in the depositary bank or the custodian the record ownership in the applicable ordinary shares with the beneficial ownership and interests in such ordinary shares being at all times vested with the beneficial owners of the ADSs representing the ordinary shares. The depositary bank or the custodian shall at all times be entitled to exercise the beneficial ownership rights in all deposited property, in each case only on behalf of the holders and beneficial owners of the ADSs representing the deposited property.

        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 amendments thereto and the form of American Depositary Receipt. This summary does not purport to be complete and is subject to and qualified in its entirety by our Form F-6 and its amendments, as filed on October 16,

2017 and August 10, 2020 (File No.333-220966). For directions on how to obtain copies of those documents, see "Where You Can Find Additional Information" in our prospectus.

Holding the ADSs

How will you hold your ADSs?

        As an owner of ADSs, you may hold your ADSs either by means of an ADR registered in your name, through a brokerage or safekeeping account, or through an account established by the depositary bank in your name reflecting the registration of uncertificated ADSs directly on the books of the depositary bank (common referred to as the "direct registration system" or "DRS"). The direct registration system reflects the uncertificated (book-entry) registration of ownership of ADSs by the depositary bank. Under the direct registration system, ownership of ADSs is evidenced by periodic statements issued by the depositary bank to the holders of the ADSs. The direct registration system includes automated transfers between the depositary bank and the Depository Trust Company ("DTC"), the central book-entry clearing and settlement system for equity securities in the United States. If you decide to hold your ADSs through your brokerage or safekeeping account, you must rely on the procedures of your broker or bank to assert your rights as ADS owner. Banks and brokers typically hold securities such as the ADSs through clearing and settlement systems such as DTC. The procedures of such clearing and settlement system may limit your ability to exercise your rights as an owner of ADSs. Please consult with your broker or bank if you have any questions concerning these limitations and procedures. All ADSs held through DTC will be registered in the name of a nominee of DTC. This summary description assumes you have opted to own the ADSs directly by means of an ADS registered in your name and, as such, we will refer to you as the "holder". When we refer to "you", we assume the reader owns ADSs and will own ADSs at the relevant time.

Dividends and Other Distributions

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

        As a holder of ADSs, you generally have the right to receive distributions we make on the securities deposited with the custodian. Your receipt of these distributions may be limited, however, by practical considerations and legal limitations. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent as of the record date (which will be as close as practicable to the record date for our ordinary shares) set by the depositary with respect to the ADSs, after deduction of the applicable fees, taxes, and expenses.

•

Cash.  The depositary will convert any cash dividend or other cash distribution we pay on the ordinary shares or any net proceeds from the sale of any ordinary shares, rights, securities or other entitlements into U.S. dollars if it can do so on a practicable basis, and can transfer the U.S. dollars to the United States. If that is not practical or lawful or if any government approval is needed and cannot be obtained, the deposit agreement allows the depositary either to distribute the foreign currency to the ADS holders or to hold the foreign currency for the account of the ADS holders, in which case it will not invest the foreign currency and it will not be liable for any interest. Before making a distribution, any taxes or other governmental charges, together with fees and expenses of the depositary, that must be paid, will be deducted. See "Description of American Depositary Shares—Fees and Expenses" and "Description of American Depositary Shares—Payment of Taxes" in our prospectus. It will distribute only such amount as can be distributed without attributing to any holder a fraction of one cent, and any balance not so distributed shall be held by the depositary (without liability for interest thereon) and shall be added to and become part of the next sum received by the depositary for distribution to holders of ADSs outstanding at the time of the next distribution. If the exchange

30

Table of Contents

rates fluctuate during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the distribution.

•

Shares.  The depositary may distribute additional ADSs representing any ordinary shares we distribute as a dividend or free distribution. The depositary will only distribute whole ADSs. It will sell any ordinary shares that would require it to deliver a fractional ADS and distribute the net proceeds in the same way as it does with cash. If the depositary does not distribute additional ADSs, the outstanding ADSs will, to the extent permissible by law, also represent the new ordinary shares. The depositary may sell all or a portion of the ordinary shares that it has not distributed, and distribute the net proceeds in the same way as it does with cash. Additionally, the depositary may sell a portion of the distributed ordinary shares sufficient to pay its fees and expenses, and any taxes and governmental charges, in connection with that distribution.



•

Elective Distributions in Cash or Shares.  If we offer holders of our ordinary shares the option to receive dividends in either cash or shares, the depositary, after consultation with us and having received timely notice as described in the deposit agreement of such elective distribution by us, will determine to what extent such elective distribution will be made available to you as a holder of the ADSs. We must first instruct the depositary to make such elective distribution available to you and furnish it with satisfactory evidence that it is legal to do so. The depositary could decide it is not legal or reasonably practical to make such elective distribution available to you. In such case, the depositary shall, on the basis of the same determination as is made in respect of the ordinary shares for which no election is made, distribute either cash, in the same way as it does in a cash distribution, or additional ADSs representing ordinary shares, in the same way as it does in a share distribution. The depositary is not obligated to make available to you a method to receive the elective dividend in shares rather than in ADSs. You may not be given the opportunity to receive elective distributions on the same terms and conditions as the holders of our ordinary shares.



•

Rights to Subscribe for Additional Shares.  If we offer holders of our ordinary shares any rights to subscribe for additional shares or any other rights, the depositary may after consultation with us and having received timely notice as described in the deposit agreement of such distribution by us, make these rights available to you. We must first instruct the depositary to make such rights available to you and furnish the depositary with satisfactory evidence that it is legal to do so. If the depositary decides it is not legal and practicable to make the rights available, or if rights have been made available but have not been exercised and appear to be about to lapse, the depositary may, if it determines it is lawful and practicable to do so, endeavor to sell the rights and distribute the net proceeds, in the same way as it does with cash. If the depositary is not able to distribute the rights or arrange for their sale, it will allow such rights that are not distributed or sold to lapse. In that case, you will receive no value for them. If the depositary makes rights available to you, it will exercise the rights and purchase the shares on your behalf. The depositary will then deposit the shares and deliver ADSs to you. It will only exercise rights if you pay it the exercise price and any other charges the rights require you to pay. The depositary will sell shares that would require it to deliver a fractional ADS and distribute the net proceeds in the same way as it does with cash.

        The depositary may sell a portion of the distributed rights sufficient to pay its fees and expenses, and any taxes and governmental charges, in connection with that distribution.

        You may not be given the opportunity to exercise rights on the same terms and conditions as the holders of ordinary shares or be able to exercise such rights.

        U.S. securities laws may restrict transfers and cancellation of the ADSs represented by shares purchased upon exercise of rights. For example, you may not be able to trade these ADSs freely in the

31

Table of Contents

United States. In this case, the depositary may deliver restricted depositary shares that have the same terms as the ADSs described in this section except for changes needed to put the necessary restrictions in place.

        The depositary bank is under no obligation to make available to you a method of exercising your rights to subscribe for Shares (rather than ADSs).

•

Other Distributions.  Subject to receipt of timely notice, as described in the deposit agreement, from us with the request to make any such distribution available to you, and provided the depositary has determined such distribution is lawful and reasonably practicable and in accordance with the terms of the deposit agreement, the depositary will send to you anything else we distribute on deposited securities by any means it thinks is practicable. If the depositary cannot make a distribution in this way, it may endeavor to sell what we distributed and distribute the net proceeds in the same way as it does with cash. If the depositary is unable to sell what we distribute, it may dispose of such property in any way it deems reasonably practicable under the circumstances for nominal or no consideration. The depositary may sell a portion of the distributed securities or property sufficient to pay its fees and expenses and any taxes and governmental charges in connection with that distribution.



•

Redemption.  Whenever we decide to redeem any of the securities on deposit with the custodian, we will notify the depositary bank in advance. If it is practicable and if we provide all of the documentation contemplated in the deposit agreement, the depositary bank will provide notice of the redemption to the holders.

        The custodian will be instructed to surrender the shares being redeemed against payment of the applicable redemption price. The depositary bank will convert the redemption funds into U.S. dollars upon the terms of the deposit agreement and will establish procedures to enable holders to receive the net proceeds from the redemption upon surrender of their ADSs to the depositary bank. You may have to pay fees, expenses, taxes, and other governmental charges upon the redemption of your ADSs. If less than all of the ADSs are being redeemed, the ADSs to be retired will be selected by lot or on a pro rata basis, as the depositary bank may determine.

        The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS 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 ADS 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.

Changes Affecting Ordinary Shares

        The ordinary shares held on deposit for your ADSs may change from time to time. For example, there may be a change in nominal or par value, split-up, cancellation, consolidation or any other reclassification of such ordinary shares or a recapitalization, reorganization, merger, consolidation or sale of assets of the Company.

        If any such change were to occur, your ADSs would, to the extent permitted by law and the deposit agreement, represent the right to receive the property received or exchanged in respect of the ordinary shares held on deposit. The depositary may in such circumstances deliver new ADSs to you, amend the deposit agreement, the applicable ADRs and the applicable Registration Statement(s) on Form F-6, call for the exchange of your existing ADSs for new ADSs and take any other actions that are appropriate to reflect as to the ADSs the change affecting the ordinary shares. If the depositary may not lawfully distribute such property to you, the depositary may sell such property and distribute the net proceeds to you as in the case of a cash distribution.

Deposit, Withdrawal and Cancellation

How are ADSs issued?

        The depositary may create ADSs on your behalf if you or your broker deposits ordinary shares or evidence of rights to receive ordinary shares with the custodian or its nominee. 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 ADSs to or upon the order of the person or persons entitled thereto. Your ability to deposit ordinary shares and receive ADSs may be limited by U.S. and Cayman Islands legal considerations applicable at the time of deposit

        When you make a deposit of the ordinary shares, you will be responsible for transferring good and valid title to the depositary bank. As such, you will be deemed to represent and warrant that:

•

The ordinary shares are duly authorized, validly issued, fully paid, non-assessable, and legally obtained.



•

All preemptive (and similar) rights, if any, with respect to such ordinary shares have been validly waived or exercised.



•

You are duly authorized to deposit the ordinary shares.



•

The ordinary shares presented for deposit are free and clear of any lien, encumbrance, security interest, charge, mortgage, or adverse claim, and are not, and the ADSs issuable upon such deposit will not be, "restricted securities" (as defined in the deposit agreement).



•

The ordinary shares presented for deposit have not been stripped of any rights or entitlements.

        If any of the representations or warranties is incorrect in any way, we and the depositary bank may, at your cost and expense, take any and all actions necessary to correct the consequences of the misrepresentations

How do ADS holders cancel an American Depositary Share and Receive the Ordinary Shares(s) Underlying such ADS?

        As a holder, you will be entitled to present your ADSs to the depositary bank for cancellation and then receive the corresponding number of underlying ordinary shares at the custodian's offices. Your ability to withdraw the ordinary shares held in respect of the ADSs may be limited by U.S. and Cayman Islands considerations applicable at the time of withdrawal. 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 ordinary shares and any other deposited securities underlying the ADSs to you or a person you designate, subject to the terms and conditions of the deposit agreement, of the ADRs evidencing the ADSs so cancelled, our amended and restated memorandum and articles of association, and of any applicable laws and regulations of the DTC, and the terms and conditions of or governing the deposited securities. The depositary may make delivery of any cash distributions, dividends, or proceeds in respect of deposited securities represented by ADSs surrendered for cancellation and withdrawal, at its principal office. At your request, risk and expense, the depositary will deliver any deposited property (other than deposited securities) held by the Custodian in respect of such ADSs at its principal office, if practicable and not illegal.

        If you hold ADSs registered in your name, the depositary bank may ask you to provide proof of identity and genuineness of any signature and such other documents as the depositary bank may deem appropriate before it will cancel your ADSs. The withdrawal of ordinary shares represented by your ADSs may be delayed until the depositary bank receives satisfactory evidence of compliance with all

33

Table of Contents

applicable laws and regulations. Please keep in mind that the depositary bank will only accept ADSs for cancellation that represent a whole number of securities on deposit.

        You have the right to cancel your ADSs and withdraw the underlying ordinary shares at any time except in the following instances:

•

when temporary delays arise because: (1) the depositary has closed its transfer books or we have closed our transfer books; (2) the transfer of ordinary shares is blocked to permit voting at a shareholders' meeting; or (3) we are paying a dividend on our ordinary shares;



•

when you owe money to pay fees, taxes and similar charges; or



•

when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities.



•

other circumstances specifically contemplated by Instruction I.A(1) of the General Instructions to Form F-6 (as such General Instructions may be amended from time to time).

The deposit agreement may not be modified to impair your right to withdraw the securities represented by your ADSs except to comply with mandatory provisions of law.

How do ADS holders interchange between Certificated ADSs and Uncertificated ADSs?

        You may surrender your ADR to the depositary for the purpose of exchanging your ADR for uncertificated ADSs. Upon payment of applicable fees and expenses and if permitted by law, the depositary will cancel that ADR and will send you a statement confirming that you are the owner of uncertificated ADSs. Alternatively, upon receipt by the depositary of a proper instruction from a holder of uncertificated ADSs requesting the exchange of uncertificated ADSs for certificated ADSs, the depositary will execute and deliver to you an ADR evidencing those ADSs.

Voting Rights

How do you vote?

        As a holder, you generally have the right under the deposit agreement to instruct the depositary bank to exercise the voting rights for the ordinary shares represented by your ADSs. The voting rights of holders of ordinary shares are described in "Description of Share Capital" in the prospectus.

        At our request, the depositary bank will distribute to you any notice of shareholders' meeting received from us together with information explaining how to instruct the depositary bank to exercise the voting rights of the securities represented by ADSs.

        If the depositary bank timely receives voting instructions from a holder of ADSs, it will endeavor to vote the securities (in person or by proxy) represented by the holder's ADSs in accordance with the voting instructions received from the holders of ADSs as follows:

•

In the event of voting by show of hands, the depositary bank will vote (or cause the custodian to vote) all ordinary shares held on deposit at that time in accordance with the voting instructions received from a majority of holders of ADSs who provide timely voting instructions.



•

In the event of voting by poll, the depositary bank will vote (or cause the custodian to vote) the ordinary shares held on deposit in accordance with the voting instructions received from the holders of ADSs.

        In the event of voting by poll, holders of ADSs in respect of which no timely voting instructions have been received shall be deemed to have instructed the depositary to give a discretionary proxy to a person designated by us to vote the ordinary shares represented by such holders' ADSs; provided, that

34

Table of Contents

no such instructions shall be deemed given and no such discretionary proxy shall be given with respect to any matter as to which we inform the depositary that we do not wish such proxy to be given; provided, further, that no such discretionary proxy shall be given (x) with respect to any matter as to which we inform the depositary that (i) there exists substantial opposition, or (ii) the rights of holders of ADSs or the shareholders of our company will be materially adversely affected, and (y) in the event that the vote is on a show of hands.

        Please note that the ability of the depositary bank to carry out voting instructions may be limited by practical and legal limitations and the terms of the securities on deposit. We cannot assure you that you will receive voting materials in time to enable you to return voting instructions to the depositary bank in a timely manner.

Payment of Taxes

        You will be responsible for any taxes or other governmental charges payable on your ADSs or on the deposited securities represented by any of your ADSs. The depositary may refuse to register any transfer your ADSs or allow you to withdraw the deposited securities represented by your ADSs until such taxes or other charges are paid. It may apply payments owed to you or sell deposited securities represented by your ADSs to pay any taxes owed and you will remain liable for any deficiency. If the depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to reflect the sale and pay to you any net proceeds, or send to you any property, remaining after it has paid the taxes. You agree to indemnify us, the depositary, the custodian and each of our and their respective agents, directors, employees and affiliates for, and hold each of them harmless from, any claims with respect to taxes (including applicable interest and penalties thereon) arising from any refund of taxes, reduced rate or withholding or other tax benefit obtained for you and any claims by any governmental authority with respect to taxes, additions to tax, penalties or interest arising out of any refund of taxes, reduced rate withholding at source or other tax benefit obtained.

How may the deposit agreement be amended?

        We may agree with the depositary to amend the deposit agreement and the form of ADR without your consent for any reason. If an amendment adds or increases fees or charges (except for taxes and

35

Table of Contents

other governmental charges or expenses of the depositary for registration fees, facsimile costs, delivery charges or similar items, including expenses incurred in connection with foreign exchange control regulations) or materially prejudices a substantial existing right of ADS holders, it will not become effective for outstanding ADSs until 30 days after the depositary notifies ADS holders of the amendment. At the time an amendment becomes effective, you are considered, by continuing to hold your ADSs, to agree to the amendment and to be bound by the ADRs and the deposit agreement as amended. If any new laws are adopted that would require the deposit agreement to be amended in order to comply therewith, we and the depositary may amend the deposit agreement in accordance with such laws and such amendment may become effective before notice thereof is given to ADS holders.

How may the deposit agreement be terminated?

        The depositary will terminate the deposit agreement if we ask it to do so, in which case the depositary will give notice to you at least 30 days prior to termination. The depositary may also terminate the deposit agreement if the depositary has told us that it would like to resign, or if we have removed the depositary, and in either case we have not appointed a new depositary within 90 days. In either such 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:

•

Collect distributions on the deposited securities.



•

Sell rights and other property.



•

Deliver ordinary shares and other deposited securities upon cancellation of ADSs after payment of any fees, charges, taxes or other governmental charges. At any time 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 ADS holders that have not surrendered their ADSs. 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 under the deposit agreement will be to indemnify the depositary and to pay fees and expenses of the depositary that we agreed to pay.

Books of Depositary

        The depositary will maintain ADS holder records at its depositary office. You may inspect such records at such office during regular business hours but solely for the purpose of communicating with other holders in the interest of the business of our company or matters relating to the ADSs or the deposit agreement.

        The depositary will maintain facilities in the Borough of Manhattan, the City of New York to record and process the issuance, cancellation, combination, split-up and transfer of ADRs. The depositary may close the transfer books with respect to the ADSs at any time or from time to time, when deemed necessary or advisable by it in good faith in connection with the performance of its duties hereunder, or at the reasonable written request of us, subject to the depositary's compliance with U.S. securities laws.

You may have to pay fees and expenses incurred in converting foreign currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.

        If the conversion of foreign currency is not practical or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the depositary bank may take the following actions in its discretion:

DESCRIPTION OF WARRANTS

        We may issue warrants for the purchase of ordinary shares. Warrants may be offered independently or together with ordinary shares offered by any prospectus supplement and may be attached to or separate from those securities. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe in particular the terms of any series of warrants that we may offer in more detail in the applicable prospectus supplement and any applicable free writing prospectus. The terms of any warrants offered under a prospectus supplement may differ from the terms described below.

        We will file as an exhibit to the registration statement of which this prospectus is a part, or will incorporate by reference from another report that we file with the SEC, the form of warrant and/or warrant agreement, which may include a form of warrant certificate, as applicable, that describes the terms of the particular series of warrants we may offer before the issuance of the related series of warrants. We may issue the warrants under a warrant agreement that we will enter into with a warrant agent to be selected by us. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any registered holders of warrants or beneficial owners of warrants. The following summary of material provisions of the warrants and warrant agreements is subject to, and qualified in its entirety by reference to, all the provisions of the form of warrant and/or warrant agreement and warrant certificate applicable to a particular series of warrants. We urge you to read the applicable prospectus supplement and any related free writing prospectus, as well as the complete form of warrant and/or the warrant agreement and warrant certificate, as applicable, that contain the terms of the warrants.

        Each warrant will entitle its holder to purchase the number of ordinary shares at the exercise price set forth in, or calculable as set forth in, the applicable prospectus supplement. The warrants may be exercised as set forth in the prospectus supplement relating to the warrants offered. Unless we otherwise specify in the applicable prospectus supplement, warrants may be exercised at any time up to the close of business on the expiration date set forth in the prospectus supplement relating to the warrants offered thereby. After the close of business on the expiration date, unexercised warrants will become void.

        We will specify the place or places where, and the manner in which, warrants may be exercised in the form of warrant, warrant agreement or warrant certificate and applicable prospectus supplement. Upon receipt of payment and the warrant or warrant certificate, as applicable, properly completed and duly executed at the corporate trust office of the warrant agent, if any, or any other office, including ours, indicated in the prospectus supplement, we will, as soon as practicable, issue and deliver the securities purchasable upon such exercise. If less than all of the warrants (or the warrants represented by such warrant certificate) are exercised, a new warrant or a new warrant certificate, as applicable, will be issued for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

        Prior to the exercise of any warrants to purchase ordinary shares, holders of the warrants will not have any of the rights of holders of ordinary shares purchasable upon exercise, including the right to vote or to receive any payments of dividends or payments upon our liquidation, dissolution or winding up on the ordinary shares purchasable upon exercise, if any.
