Industry publications and third-party research, surveys and studies generally indicate that their information has been obtained from sources believed to be reliable, although they do not guarantee the accuracy or completeness of such information. Our estimates of the potential market opportunities for our product candidate include several key assumptions based on our industry knowledge, industry publications, third-party research and other surveys, which may be based on a small sample size and may fail to accurately reflect market opportunities.

OUR COMPANY

Our Business

Through the operating entities, we are a crypto asset technology company based in the U.S. with a focus on bitcoin mining. We also generate revenue through mining machines resale and rental business operations. For the fiscal year ended December 31, 2023, we generated a substantial majority of our revenue from bitcoin mining.

No CSRC Filing Requirement

On February 17, 2023, China Securities Regulatory Commission (the "CSRC") promulgated the Trial Administrative Measures of the Overseas Securities Offering and Listing by Domestic Companies, or the Trial Measures, and the relevant five guidelines, which became effective on March 31, 2023. Pursuant to the Trial Measures, PRC domestic companies that seek to offer and list securities in overseas markets, either in direct or indirect means, are required to fulfill the filing procedure with the CSRC and report relevant information. The Trial Measures provides that if the issuer meets both of the following criteria, the overseas securities offering and listing conducted by such issuer will be deemed as indirect overseas offering by PRC domestic companies: (i) 50% or more of any of the issuer's operating revenue, total profit, total assets or net assets as documented in its audited consolidated financial statements for the most recent fiscal year is accounted for by domestic companies; and (ii) the main parts of the issuer's business activities are conducted in mainland China, or its main place(s) of business are located in mainland China, or the majority of senior management staff in charge of its business operations and management are PRC citizens or have their usual place(s) of residence located in mainland China. As advised by Allbright Law Offices, our counsel as to PRC law, as of the date of this prospectus, in connection with this offering, under current PRC laws, regulations and rules, we are not required to submit applications for the approval of the CSRC based on the facts that (i) we are a company incorporated in the Cayman Islands, with 50% or more of our operating revenue, total profit, total assets or net assets in the fiscal year ended December 31, 2023 generated outside of mainland China; (ii) our business activities are not primarily conducted in mainland China, the main places of the our business are located in mainland China; and the majority of senior management staff of the Company in charge of its business operations and management are PRC citizens and have their usual places of residence located in mainland China.

DESCRIPTION OF SHARE CAPITAL

We are an exempted company incorporated under the laws of the Cayman Islands and our affairs are governed by our currently effective amended and restated memorandum and articles of association (the "Memorandum and Articles of Association"), and Companies Act (Revised) of the Cayman Islands (the "Companies Act"), and the common law of the Cayman Islands.

Our ordinary shares are listed and traded on The Nasdaq Capital Market under the ticker symbol "BTCT" and are registered under Section 12(b) of the Exchange Act. In addition, our warrants are quoted on The Nasdaq Capital Market under the ticker symbol "BTCTW." This exhibit contains a description of the rights of the holders of ordinary shares and warrants.

3

Rights of ordinary shares

Ordinary Shares

Our authorized share capital is US$1,500,000 divided into 25,000,000 ordinary shares, par value $0.06 per share. All of our issued and outstanding ordinary shares are fully paid and non-assessable. Shareholders who are non-residents of the Cayman Islands may freely hold and transfer their ordinary shares.

Dividends

The holders of our ordinary shares are entitled to such dividends as may be declared by our board of directors or declared by our shareholders by ordinary resolution (provided that no dividend may be declared by our shareholders which exceeds the amount recommended by our directors). Our Memorandum and Articles of Association provide that dividends may be declared and paid out of funds of our Company lawfully available therefor. Dividends may also be declared and paid out of share premium account or any other fund or account which can be authorized for this purpose in accordance with the Companies Act.

Voting Rights

In respect of all matters subject to a shareholders' vote, holders of ordinary shares shall, at all times, vote together as one class on all matters submitted to a vote by the members at any such general meeting. Each ordinary share shall be entitled to one vote on all matters subject to the vote at our general meetings. 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 such meeting or any one or more shareholders representing not less than 10% of the total voting rights of all the shareholders present in person or by proxy entitled to vote at the meeting.

An ordinary resolution to be passed at a meeting by the shareholders requires the affirmative vote of a simple majority of the votes attaching to the ordinary shares cast at a meeting, while a special resolution requires the affirmative vote of no less than two-thirds of the votes cast attaching to the outstanding ordinary shares at a meeting and includes a unanimous written resolution. A special resolution will be required for important matters such as a change of name, reducing the share capital or making changes to our Memorandum and Articles of Association to be in effect.

Transfer of Ordinary Shares

The instrument of transfer of any ordinary share shall be in writing and in any usual or common form or in a form prescribed by Nasdaq or such other form approved by our board of directors and be executed by or on behalf of the transferor or, if the transferor or transferee is a clearing house or a central depository house or its nominee(s), by hand or by electronic machine imprinted signature or by such other manner of execution as the Board may approve from time to time.

The instrument of transfer shall be executed by or on behalf of the transferor and the transferee provided that our board of directors may dispense with the execution of the instrument of transfer by the transferee in any case which it thinks fit in its discretion to do so.

4

Our board of directors may, in its absolute discretion, and without giving any reason therefore, decline to register any transfer of any ordinary share that has not been fully paid up, issued under any share incentive plan for employees upon which a restriction on transfer still subsists, or is subject to a company lien. Our board of directors may also decline to register any transfer of such ordinary share unless:

a) 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;
b) the instrument of transfer is in respect of only one class of shares;
c) the instrument of transfer is lodged at the registered office or such other place at which the our register of members is kept in accordance with the accompanied by any relevant share certificate(s) and/or such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer (and, if the instrument of transfer is executed by some other person on his behalf, the authority of that person so to do); and
d) if applicable, the instrument of transfer is duly and properly stamped.

If our board of directors refuses to register a transfer, it shall, within three months after the date on which the instrument of transfer was lodged with us, to send to each of the transferor and the transferee notice of such refusal.

The registration of transfers may, after compliance with any notice requirement of Nasdaq, be suspended and our register of members closed at such times and for such periods (not exceeding in the whole thirty (30) days in any year) as our board of directors may from time to time determine.

Liquidation

On the 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 in proportion to the capital paid up, or which ought to have been paid up, at the commencement of the winding up, on the shares held by them respectively.

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 clear days in advance. The notice shall name a further day on or before which the payment required by the notice is to be made and where the payment is required to be made to.

If a call remains unpaid after it has become due and payable our board of directors may give to such shareholder a 14 clear days' notice:

a) requiring payment of the unpaid together with any interest which may have accrued and which may still accrue up to the date of actual payment; and
b) stating that if such notice is not complied with the shares on which the call was made will be liable to be forfeited.

If the requirements of any such notice are not complied with, any share in respect of which such notice has been given any at any time thereafter, before payment of all calls and interest due in respect thereof has been made, be forfeited by a resolution of our board of directors to that effect, and such forfeiture shall include all dividends and bonuses declared in respect of the forfeited share but not actually paid before the forfeiture.

Requirements to Change the Rights of Holders of Ordinary Shares

Variations of Rights of Shares

Whenever our capital is divided into different classes of shares, the rights attaching to any class of share (unless otherwise provided by the terms of issue of the shares of that class) may be varied with the consent in writing of the holders of not less than two-thirds of the issued shares of that class or with the sanction of a special resolution passed by at least a two-thirds majority of the holders of the shares of that class. The necessary quorum shall be one or more persons holding or representing by proxy at least one-third of the voting power of the issued shares of the relevant class (but so that if at any adjourned meeting of such holders a quorum as above defined is not present, those shareholders who are present shall form a quorum).

5

Unless the terms on which a class of shares was issued state otherwise, the rights conferred on the shareholder holding shares of any class shall not be deemed to be varied by the creation or issue of further shares ranking pari passu with the existing shares of that class or subsequent to them or the redemption or purchase of any shares of any class by our company.

Limitations on the Rights to Own Ordinary Shares

There are no limitations under the laws of the Cayman Islands or under our Memorandum and Articles of Association that limit the right of non-resident or foreign owners to hold or vote ordinary shares.

Provisions Affecting Any Change of Control

Anti-Takeover Provisions. Some provisions of our 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 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.

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our 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.

Ownership Threshold

There are no provisions under the Companies Act or under the Memorandum and Articles of Association that govern the ownership threshold above which shareholder ownership must be disclosed.

Differences Between the Law of Different Jurisdictions

The Companies Act is modelled after that of England and Wales but does not follow recent statutory enactments in England. In addition, the Companies Act 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 Act applicable to us and the laws applicable to companies incorporated in the State of Delaware

Mergers and Similar Arrangements

A merger of two or more constituent companies under Cayman Islands law requires a plan of merger or consolidation to be approved by the directors of each constituent company and authorization by a special resolution of the members of each constituent company.

A merger between a Cayman parent company and its Cayman subsidiary or subsidiaries does not require authorization by a resolution of shareholders. For this purpose a subsidiary is a company of which at least ninety percent (90%) of the issued shares entitled to vote are owned by the parent company.

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 circumstances, a dissentient shareholder of a Cayman constituent company is entitled to payment of the fair value of his shares upon dissenting to a merger or consolidation. The exercise of appraisal rights will preclude the exercise of any other rights save for the right to seek relief on the grounds that the merger or consolidation is void or unlawful.

6

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:

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

When a takeover offer is made and accepted by holders of 90% of the shares within four months, the offeror may, within a two-month period commencing on the expiration of such four 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 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 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, there are exceptions to the foregoing principle, including when:

a company acts or proposes to act illegally or ultra vires;
the act complained of, although not ultra vires, could only be effected duly if authorized by more than a simple majority vote that has not been obtained; and
those who control the company are perpetrating a "fraud on the minority."

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 Memorandum and Articles of Association provide that we shall indemnify our directors, secretary and other officers for the time being of our company and our liquidator or trustees (if any) for the time being acting in relation to any of the affairs of our company and each of them, and each of their heirs, executors and administrators, shall be indemnified and secured harmless out of the assets and profits of our company from and against all actions, costs, charges, losses, damages and expenses which they or any of them, their or any of their heirs, executors or administrators, shall or may incur or sustain by or by reason of any act done, concurred in or omitted in or about the execution of their duty, or supposed duty, in their respective offices or trusts; and none of them shall be answerable for the acts, receipts, neglects or defaults of the other or others of them or for joining in any receipts for the sake of conformity, or for any bankers or other persons with whom any moneys or effects belonging to our company shall or may be lodged or deposited for safe custody, or for insufficiency or deficiency of any security upon which any moneys of or belonging to our company shall be placed out on or invested, or for any other loss, misfortune or damage which may happen in the execution of their respective offices or trusts, or in relation thereto, provided that the indemnity shall not extend to any matter in respect of any fraud or dishonesty which may attach to any of said persons. 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 Memorandum and Articles of Association.

Anti-Takeover Provisions in our Memorandum and Articles of Association

Some provisions of our Memorandum and Articles of Association may discourage, delay or prevent a change in control of our company or management that shareholders may consider favourable, 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.

However, under Cayman Islands law, our directors may only exercise the rights and powers granted to them under our 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 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) and 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. 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. Our Memorandum and Articles of Association provide that shareholders may not 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.

8

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.

As an exempted Cayman Islands company, we are not obliged by law to call shareholders' annual general meetings or allow our shareholders to requisition a shareholders' meeting. Our Memorandum and Articles of Association allow our shareholders to requisition shareholders' meetings.

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. As permitted under Cayman Islands law, our 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 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 Memorandum and Articles of Association, directors may be removed by an ordinary resolution of 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 and for a proper corporate purpose and not with the effect of constituting a fraud on the minority shareholders.

9

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 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 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 and our Memorandum and 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

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 Memorandum and 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 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. As permitted by Cayman Islands law, our Memorandum and Articles of Association may only be amended by a special resolution of shareholders.

Rights of Non-Resident or Foreign Shareholders

There are no limitations imposed by our 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 Memorandum and Articles of Association governing the ownership threshold above which shareholder ownership must be disclosed.

Directors' Power to Issue Shares

Subject to applicable law, our board of directors is empowered to issue or allot shares or grant options and warrants with or without preferred, deferred, qualified or other special rights or restrictions.

Changes in Capital

We may from time to time by ordinary resolution:

increase the share capital by such sum, to be divided into shares of such 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;
divide the shares into several classes and without prejudice to any special rights previously conferred on the holders of existing shares attach thereto respectively any preferential, deferred, qualified or special rights, privileges, conditions or such restrictions which in the absence of any such determination by our shareholders, as the board of directors may determine;
sub-divide our existing shares, or any of them into shares of a smaller amount than that fixed by the our Memorandum of Association; and
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 its share capital by the amount of the ordinary shares so cancelled.

10

We may by special resolution, subject to any confirmation or consent required by the Companies Act, reduce our share capital or any capital redemption reserve in any manner permitted by law.

Debt Securities

Not applicable.

Warrants and Rights

As of the date of this prospectus, we had 5,316,025 warrants issued and outstanding, out of which 3,853,376 warrants are quoted on The Nasdaq Capital Market under the ticker symbol "BTCTW."

Exercise Price and Exercise Price Adjustment

The exercise price and number of ordinary shares issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a share dividend, or recapitalization, reorganization, merger or consolidation. However, the warrants will not be adjusted for issuance of ordinary shares at a price below its exercise price.

Currently, each warrant is exercisable to purchase 1/600 ordinary share at an exercise price of $6,900 per share.

Duration of Warrants

The warrants may be exercised any time and from time to time beginning on March 30, 2020 until the earlier of March 30, 2025 or the date on which we elect to redeem all of our warrants.

Exercise of Warrants

The warrants may be exercised upon the surrender of the certificate evidencing such warrant on or before the expiration date at the offices of the warrant agent, Continental Stock Transfer & Trust Company, in the Borough of Manhattan, City and State of New York, with the subscription form, as set forth in the warrants, duly executed, accompanied by full payment of the exercise price, by certified or official bank check payable to us, for the number of warrants being exercised.

Redemption

We may redeem the outstanding warrants in whole and not in part, at a price of $0.01 per warrant, upon not less than 30 days' prior written notice of redemption (the "30-day redemption period") to each warrant holder, and if, and only if, the reported last sale price of the ordinary shares (or the closing bid price of ordinary shares in the event the ordinary shares are not traded on any specific day) equals or exceeds $495.00 per share, subject to adjustment, for any 20 trading days within a 30 trading day period ending three business days before the redemption notice is sent to the warrant holders. We will not redeem the warrants unless an effective registration statement covering the ordinary shares issuable upon exercise of the warrants is current and available throughout the 30-day redemption period.

If we call the warrants for redemption as described above, we will have the option to require all holders that wish to exercise warrants to do so on a "cashless basis." In such event, each holder would pay the exercise price by surrendering the warrants for that number of ordinary shares equal to the quotient obtained by dividing (x) the product of the number of ordinary shares underlying the warrants, multiplied by the difference between the exercise price of the warrants and the "fair market value" (defined below) by (y) the fair market value. In this case, the "fair market value" shall mean the average reported last sale price of the ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

11

Registration of our Ordinary Shares

No warrants will be exercisable for cash unless we have an effective and current registration statement covering the ordinary shares issuable upon exercise of the warrants and a current prospectus relating to such ordinary shares is available, and such shares are registered, qualified or exempt from registration under the securities laws of the state of residence of the holder. If we during any period fail to have maintained an effective registration statement covering the our ordinary shares issuable upon exercise of the warrants, the warrant holders shall have the right to exercise such warrants on a "cashless basis."

Tender Offer to Exercise Warrants

As of November 30, 2020, we had outstanding 12,705,000 warrants to purchase 12,705,000 ordinary shares. On December 7, 2020, we filed a tender offer statement on Schedule TO, as amended (File number: 005-91479) in relation to our offer to the holders of outstanding warrants to purchase 12,705,000 ordinary shares, each with an exercise price of $11.50 per share, the opportunity to exercise the warrants at a temporarily reduced price of $1.40 per ordinary share. The tender offer for warrants terminated on January 5, 2021. Upon completion of the offer to exercise, 4,423,062 warrants had been validly tendered for cash exercise. In addition, 2,629,812 warrants had been validly tendered for cashless exercise, resulting in the issuance of 1,364,512 ordinary shares.

Effective January 6, 2021, we temporarily reduced the exercise price of all outstanding warrants to $2.50 per share, and has added a "full-ratchet" anti-dilution protection with respect to subsequent equity sales in which any person will be entitled to acquire ordinary shares at an effective price per share that is lower than the then exercise price of the warrants, subject to customary exceptions (the "Temporary Reduction Period"). As a result of our offering of 40,000,000 ordinary shares at a price of $1.0 per share, which was on May 25, 2021, the exercise price of the warrants was reduced to $1.0 per warrant. On September 7, 2021, we closed our offering of $60 million of ordinary shares and pre-funded warrants, at a price of $0.30 per share and $0.2999 per pre-funded warrant. As a result of that offering, the exercise price of the warrants was reduced to $0.30 per warrant. The exercise price of the warrants was later adjusted to $9.00 on May 4, 2022, following the effectiveness of our 30-to-1 share consolidation. The Temporary Reduction Period will terminate on the date following which the closing price of the Ordinary Shares has been equal to or greater than $90.00 per share for at least twenty (20) trading days during the preceding thirty (30) trading day period.

DESCRIPTION OF DEBT SECURITIES

General

We may issue debt securities which may or may not be converted into our ordinary shares or preferred shares. We may issue the debt securities independently or together with any underlying securities, and debt securities may be attached or separate from the underlying securities. In connection with the issuance of any debt securities, we do not intend to issue them pursuant to a trust indenture upon reliance of Section 304(a)(8) of the Trust Indenture Act and Rule 4a-1 promulgated thereunder.

The following description is a summary of selected provisions relating to the debt securities that we may issue. The summary is not complete. When debt securities are offered in the future, a prospectus supplement, information incorporated by reference, or a free writing prospectus, as applicable, will explain the particular terms of those securities and the extent to which these general provisions may apply. The specific terms of the debt securities as described in a prospectus supplement, information incorporated by reference, or free writing prospectus will supplement and, if applicable, may modify or replace the general terms described in this section.

This summary and any description of debt securities in the applicable prospectus supplement, information incorporated by reference, or free writing prospectus is subject to and is qualified in its entirety by reference to all the provisions of any specific debt securities document or agreement. We will file each of these documents, as applicable, with the SEC and incorporate them by reference as an exhibit to the registration statement of which this prospectus is a part on or before the time we issue a series of warrants. See "Where You Can Find Additional Information" and "Incorporation of Documents by Reference" below for information on how to obtain a copy of a debt securities document when it is filed.

12

When we refer to a series of debt securities, we mean all debt securities issued as part of the same series under the applicable indenture.

Terms

The applicable prospectus supplement, information incorporated by reference, or free writing prospectus, may describe the terms of any debt securities that we may offer, including, but not limited to, the following:

the title of the debt securities;
the total amount of the debt securities;
the amount or amounts of the debt securities will be issued and interest rate;
the conversion price at which the debt securities may be converted;
the date on which the right to convert the debt securities will commence and the date on which the right will expire;
if applicable, the minimum or maximum amount of debt securities that may be converted at any one time;
if applicable, a discussion of material federal income tax consideration;
if applicable, the terms of the payoff of the debt securities;
the identity of the indenture agent, if any;
the procedures and conditions relating to the conversion of the debt securities; and
any other terms of the debt securities, including terms, procedure and limitation relating to the exchange or conversion of the debt securities.

Form, Exchange, and Transfer

We may issue the debt securities in registered form or bearer form. Debt securities issued in registered form, i.e., book-entry form, will be represented by a global security registered in the name of a depository, which will be the holder of all the debt securities represented by the global security. Those investors who own beneficial interests in global debt securities will do so through participants in the depository's system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depository and its participants. In addition, we may issue debt securities in non-global form, i.e., bearer form. If any debt securities are issued in non-global form, debt securities certificates may be exchanged for new debt securities certificates of different denominations, and holders may exchange, transfer, or convert their debt securities at the debt securities agent's office or any other office indicated in the applicable prospectus supplement, information incorporated by reference or free writing prospectus.

Prior to the conversion of their debt securities, holders of debt securities convertible for ordinary shares or preferred shares will not have any rights of holders of ordinary shares or preferred shares, and will not be entitled to dividend payments, if any, or voting rights of the ordinary shares or preferred shares.

Conversion of Debt Securities

A debt security may entitle the holder to purchase, in exchange for the extinguishment of debt, an amount of securities at a conversion price that will be stated in the debt security. Debt securities may be converted at any time up to the close of business on the expiration date set forth in the terms of such debt security. After the close of business on the expiration date, debt securities not exercised will be paid in accordance with their terms.

Debt securities may be converted as set forth in the applicable offering material. Upon receipt of a notice of conversion properly completed and duly executed at the corporate trust office of the indenture agent, if any, or to us, we will forward, as soon as practicable, the securities purchasable upon such exercise. If less than all of the debt security represented by such security is converted, a new debt security will be issued for the remaining debt security.

13

DESCRIPTION OF WARRANTS

General

We may issue warrants to purchase our securities. We may issue the warrants independently or together with any underlying securities, and the warrants may be attached or separate from the underlying securities. We may also issue a series of warrants under a separate warrant agreement to be entered into between us and a warrant agent. The warrant agent will act solely as our agent in connection with the warrants of such series and will not assume any obligation or relationship of agency for or with holders or beneficial owners of warrants.

The following description is a summary of selected provisions relating to the warrants that we may issue. The summary is not complete. When warrants are offered in the future, a prospectus supplement, information incorporated by reference, or a free writing prospectus, as applicable, will explain the particular terms of those securities and the extent to which these general provisions may apply. The specific terms of the warrants as described in a prospectus supplement, information incorporated by reference, or free writing prospectus will supplement and, if applicable, may modify or replace the general terms described in this section.

This summary and any description of warrants in the applicable prospectus supplement, information incorporated by reference, or free writing prospectus is subject to and is qualified in its entirety by reference to all the provisions of any specific warrant document or agreement, if applicable. We will file each of these documents, as applicable, with the SEC and incorporate them by reference as an exhibit to the registration statement of which this prospectus is a part on or before the time we issue a series of warrants. See "Where You Can Find Additional Information" and "Incorporation of Documents by Reference" below for information on how to obtain a copy of a warrant document when it is filed.

When we refer to a series of warrants, we mean all warrants issued as part of the same series under the applicable warrant agreement.

Terms

The applicable prospectus supplement, information incorporated by reference, or free writing prospectus, may describe the terms of any warrants that we may offer, including, but not limited to, the following:

the title of the warrants;
the total number of warrants;
the price or prices at which the warrants will be issued;
the price or prices at which the warrants may be exercised;
the currency or currencies that investors may use to pay for the warrants;
the date on which the right to exercise the warrants will commence and the date on which the right will expire;
whether the warrants will be issued in registered form or bearer form;
information with respect to book-entry procedures, if any;
if applicable, the minimum or maximum amount of warrants that may be exercised at any one time;
if applicable, the designation and terms of the underlying securities with which the warrants are issued and the number of warrants issued with each underlying security;
if applicable, the date on and after which the warrants and the related underlying securities will be separately transferable;
if applicable, a discussion of material federal income tax considerations;
if applicable, the terms of redemption of the warrants;
the identity of the warrant agent, if any;
the procedures and conditions relating to the exercise of the warrants; and
any other terms of the warrants, including terms, procedures, and limitations relating to the exchange and exercise of the warrants.

14

Warrant Agreement

We may issue the warrants in one or more series under one or more warrant agreements, each to be entered into between us and a bank, trust company, or other financial institution as warrant agent. We may add, replace, or terminate warrant agents from time to time. We may also choose to act as our own warrant agent or may choose one of our subsidiaries to do so.

The warrant agent under a warrant agreement will act solely as our agent in connection with the warrants issued under that agreement. Any holder of warrants may, without the consent of any other person, enforce by appropriate legal action, on its own behalf, its right to exercise those warrants in accordance with their terms.

Form, Exchange, and Transfer

We may issue the warrants in registered form or bearer form. Warrants issued in registered form, i.e., book-entry form, will be represented by a global security registered in the name of a depository, which will be the holder of all the warrants represented by the global security. Those investors who own beneficial interests in a global warrant will do so through participants in the depository's system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depository and its participants. In addition, we may issue warrants in non-global form, i.e., bearer form. If any warrants are issued in non-global form, warrant certificates may be exchanged for new warrant certificates of different denominations, and holders may exchange, transfer, or exercise their warrants at the warrant agent's office or any other office indicated in the applicable prospectus supplement, information incorporated by reference, or free writing prospectus.

Prior to the exercise of their warrants, holders of warrants exercisable for ordinary shares or preferred shares will not have any rights of holders of ordinary shares or preferred shares and will not be entitled to dividend payments, if any, or voting rights of the ordinary shares or preferred shares.

Exercise of Warrants

A warrant will entitle the holder to purchase for cash an amount of securities at an exercise price that will be stated in, or that will be determinable as described in, the applicable prospectus supplement, information incorporated by reference, or free writing prospectus. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable offering material. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be redeemed as set forth in the applicable offering material.

Warrants may be exercised as set forth in the applicable offering material. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable offering material, we will forward, as soon as practicable, the securities purchasable upon such exercise. If less than all of the warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

DESCRIPTION OF RIGHTS

We may issue rights to purchase our securities. The rights may or may not be transferable by the persons purchasing or receiving the rights. In connection with any rights offering, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such rights offering. Each series of rights will be issued under a separate rights agent agreement to be entered into between us and one or more banks, trust companies, or other financial institutions, as rights agent, that we will name in the applicable prospectus supplement. The rights agent will act solely as our agent in connection with the rights and will not assume any obligation or relationship of agency or trust for or with any holders of rights certificates or beneficial owners of rights.

15

The prospectus supplement relating to any rights that we offer will include specific terms relating to the offering, including, among other matters:

the date of determining the security holders entitled to the rights distribution;
the aggregate number of rights issued and the aggregate amount of securities purchasable upon exercise of the rights;
the exercise price;
the conditions to completion of the rights offering;
the date on which the right to exercise the rights will commence and the date on which the rights will expire; and
any applicable federal income tax considerations.

Each right would entitle the holder of the rights to purchase for cash the principal amount of securities at the exercise price set forth in the applicable prospectus supplement. Rights may be exercised at any time up to the close of business on the expiration date for the rights provided in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised rights will become void.

If less than all of the rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than our security holders, to or through agents, underwriters, or dealers, or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

DESCRIPTION OF UNITS

We may issue units composed of any combination of our securities. We will issue each unit so that the holder of the unit is also the holder of each security included in the unit. As a result, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The following description is a summary of selected provisions relating to units that we may offer. The summary is not complete. When units are offered in the future, a prospectus supplement, information incorporated by reference, or a free writing prospectus, as applicable, will explain the particular terms of those securities and the extent to which these general provisions may apply. The specific terms of the units as described in a prospectus supplement, information incorporated by reference, or free writing prospectus will supplement and, if applicable, may modify or replace the general terms described in this section.

This summary and any description of units in the applicable prospectus supplement, information incorporated by reference, or free writing prospectus is subject to and is qualified in its entirety by reference to the unit agreement, collateral arrangements, and depositary arrangements, if applicable. We will file each of these documents, as applicable, with the SEC and incorporate them by reference as an exhibit to the registration statement of which this prospectus is a part on or before the time we issue a series of units. See "Where You Can Find Additional Information" and "Incorporation of Documents by Reference" below for information on how to obtain a copy of a document when it is filed.

The applicable prospectus supplement, information incorporated by reference, or free writing prospectus may describe:

The designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;
Any provisions for the issuance, payment, settlement, transfer, or exchange of the units or of the securities composing the units;
Whether the units will be issued in fully registered or global form; and
Any other terms of the units.

The applicable provisions described in this section, as well as those described under "Description of Share Capital," "Description of American Depositary Shares," "Description of Debt Securities," "Description of Warrants," and "Description of Rights" above, will apply to each unit and to each security included in each unit, respectively.

ENFORCEABILITY OF CIVIL LIABILITIES

We were incorporated in the Cayman Islands, as an exempted company, in order to enjoy the following benefits:

political and economic stability;
an effective judicial system;
a favorable tax system;
the absence of exchange control or currency restrictions; and
the availability of professional and support services.

However, certain disadvantages accompany incorporation in the Cayman Islands. These disadvantages include, but are not limited to, the following:

the Cayman Islands has a less developed body of securities laws as compared to the United States and these securities laws provide significantly less protection to investors as compared to the United States; and
Cayman Islands companies may not have standing to sue before the federal courts of the United States.

Our constitutional 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.

All of our operations are conducted outside the United States, and all of our assets are located outside the United States. 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 these persons, or to enforce against us or them judgments obtained in U.S. courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States.

We have appointed Puglisi & Associates as our agent upon whom process may be served in any action brought against us under the securities laws of the United States.

Conyers Dill & Pearman, our counsel as to Cayman Islands law, has advised us that there is uncertainty as to whether the courts of the Cayman Islands, would:

recognize or enforce judgments of U.S. courts obtained against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States so far as the liabilities imposed by those provisions are penal in nature; or
entertain original actions brought in each respective jurisdiction against us or our directors or officers predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States.

Our counsel with respect to the laws of the Cayman Islands has advised us that it is uncertain whether the courts of the Cayman Islands will allow shareholders of our company to originate actions in the Cayman Islands based upon securities laws of the United States. In addition, there is uncertainty with regard to Cayman Islands law related to whether a judgment obtained from the U.S. courts under civil liability provisions of U.S. securities laws will be determined by the courts of the Cayman Islands as penal or punitive in nature. If such a determination is made, the courts of the Cayman Islands will not recognize or enforce the judgment against a Cayman Islands company, such as our company. As the courts of the Cayman Islands have yet to rule on making such a determination in relation to judgments obtained from U.S. courts under civil liability provisions of U.S. securities laws, it is uncertain whether such judgments would be enforceable in the Cayman Islands. Our counsel has further advised us that although there is no statutory enforcement in the Cayman Islands of judgments obtained in the federal or state courts of the United States (and the Cayman Islands are not a party to any treaties for the reciprocal enforcement or recognition of such judgments), a judgment obtained in such jurisdiction will be recognized and enforced in the courts of the Cayman Islands at common law, without any reexamination of the merits of the underlying dispute, by an action commenced on the foreign judgment debt in the Grand Court of the Cayman Islands, provided (a) such courts had proper jurisdiction over the parties subject to such judgment; (b) such courts did not contravene the rules of natural justice of the Cayman Islands; (c) such judgment was not obtained by fraud; (d) the enforcement of the judgment would not be contrary to the public policy of the Cayman Islands; (e) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of the Cayman Islands; and (f) there is due compliance with the correct procedures under the laws of the Cayman Islands.

PLAN OF DISTRIBUTION

We may sell the securities offered by this prospectus from time to time in one or more transactions, including, without limitation:

through agents;
to or through underwriters;
through broker-dealers (acting as agent or principal);
directly by us to purchasers (including our affiliates and shareholders), through a specific bidding or auction process, a rights offering, or other method;
through a combination of any such methods of sale; or
through any other methods described in a prospectus supplement.

The distribution of securities may be effected, from time to time, in one or more transactions, including:

block transactions (which may involve crosses) and transactions on Nasdaq or any other organized market where the securities may be traded;
purchases by a broker-dealer as principal and resale by the broker-dealer for its own account pursuant to a prospectus supplement;
ordinary brokerage transactions and transactions in which a broker-dealer solicits purchasers;
sales "at the market" to or through a market maker or into an existing trading market, on an exchange or otherwise; and
sales in other ways not involving market makers or established trading markets, including direct sales to purchasers.

The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash, extinguishment of debt, or another form negotiated by the parties. Agents, underwriters, or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions, or commissions to be received from us or from the purchasers of the securities. Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

We may also make direct sales through subscription rights distributed to our existing shareholders on a pro rata basis, which may or may not be transferable. In any distribution of subscription rights to our shareholders, if all of the underlying securities are not subscribed for, we may then sell the unsubscribed securities directly to third parties or may engage the services of one or more underwriters, dealers, or agents, including standby underwriters, to sell the unsubscribed securities to third parties.

Some or all of the securities that we offer through this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.

18

Agents may, from time to time, solicit offers to purchase the securities. If required, we will name in the applicable prospectus supplement, document incorporated by reference, or free writing prospectus, as applicable, any agent involved in the offer or sale of the securities and set forth any compensation payable to the agent. Unless otherwise indicated, any agent will be acting on a best efforts basis for the period of its appointment. Any agent selling the securities covered by this prospectus may be deemed to be an underwriter of the securities.

If underwriters are used in an offering, securities will be acquired by the underwriters for their own account and may be resold, from time to time, in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, or under delayed delivery contracts or other contractual commitments. Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. If an underwriter or underwriters are used in the sale of securities, an underwriting agreement will be executed with the underwriter or underwriters at the time an agreement for the sale is reached. The applicable prospectus supplement will set forth the managing underwriter or underwriters, as well as any other underwriter or underwriters, with respect to a particular underwritten offering of securities, and will set forth the terms of the transactions, including compensation of the underwriters and dealers and the public offering price, if applicable. This prospectus, the applicable prospectus supplement and any applicable free writing prospectus will be used by the underwriters to resell the securities.

If a dealer is used in the sale of the securities, we, or an underwriter, will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, we will set forth in the prospectus supplement, document incorporated by reference, or free writing prospectus, as applicable, the name of the dealer and the terms of the transactions.

We may directly solicit offers to purchase the securities and may make sales of securities directly to institutional investors or others. These persons may be deemed to be underwriters with respect to any resale of the securities. To the extent required, the prospectus supplement, document incorporated by reference, or free writing prospectus, as applicable, will describe the terms of any such sales, including the terms of any bidding or auction process, if used.

Agents, underwriters, and dealers may be entitled under agreements which may be entered into with us to indemnification by us against specified liabilities, including liabilities incurred under the Securities Act, or to contribution by us to payments they may be required to make in respect of such liabilities. If required, the prospectus supplement, document incorporated by reference, or free writing prospectus, as applicable, will describe the terms and conditions of such indemnification or contribution. Some of the agents, underwriters, or dealers, or their affiliates may be customers of, engage in transactions with or perform services for us or our subsidiaries or affiliates in the ordinary course of business.

Under the securities laws of some states, the securities offered by this prospectus may be sold in those states only through registered or licensed brokers or dealers.

Any person participating in the distribution of securities registered under the registration statement that includes this prospectus will be subject to applicable provisions of the Exchange Act, and the applicable SEC rules and regulations, including, among others, Regulation M, which may limit the timing of purchases and sales of any of our securities by any such person. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of our securities to engage in market-making activities with respect to our securities.

These restrictions may affect the marketability of our securities and the ability of any person or entity to engage in market-making activities with respect to our securities.

Certain persons participating in an offering may engage in over-allotment, stabilizing transactions, short-covering transactions, and penalty bids in accordance with Regulation M under the Exchange Act that stabilize, maintain, or otherwise affect the price of the offered securities. If any such activities will occur, they will be described in the applicable prospectus supplement.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution.

Our Memorandum and Articles of Association provide that we shall indemnify our directors, secretary and other officers for the time being of our company and our liquidator or trustees (if any) for the time being acting in relation to any of the affairs of our company and each of them, and each of their heirs, executors and administrators, shall be indemnified and secured harmless out of the assets and profits of our company from and against all actions, costs, charges, losses, damages and expenses which they or any of them, their or any of their heirs, executors or administrators, shall or may incur or sustain by or by reason of any act done, concurred in or omitted in or about the execution of their duty, or supposed duty, in their respective offices or trusts; and none of them shall be answerable for the acts, receipts, neglects or defaults of the other or others of them or for joining in any receipts for the sake of conformity, or for any bankers or other persons with whom any moneys or effects belonging to our company shall or may be lodged or deposited for safe custody, or for insufficiency or deficiency of any security upon which any moneys of or belonging to our company shall be placed out on or invested, or for any other loss, misfortune or damage which may happen in the execution of their respective offices or trusts, or in relation thereto, provided that the indemnity shall not extend to any matter in respect of any fraud or dishonesty which may attach to any of said persons.

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that subparagraphs (i), (ii), and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

II-3

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(d) The registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Securities and Exchange Commission under Section 305(b)(2) of the Trust Indenture Act.
