The Registration Statement was declared effective on March 12, 2021. This Post-Effective Amendment No. 1 to Form F-1 on Form F-3 is being filed to (i) convert the registration statement on Form F-1 to a registration statement on Form F-3 and (ii) update certain other information in the prospectus relating to the offering and sale of the common shares that were registered for resale on the Registration Statement.

TABLE OF CONTENTS

The information in this prospectus is not complete and may be changed. The selling shareholders may not sell these securities until the registration statement filed with the Securities and Exchange Commission is effective. This prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any state where the offer or sale is not permitted.

SUBJECT TO COMPLETION, DATED APRIL 16, 2021

PROSPECTUS

43,738,900 Common Shares

Offered by the Selling Shareholders

Seanergy Maritime Holdings Corp.

This prospectus relates to the resale, from time to time, by the selling shareholders identified in this prospectus under the caption “Selling Shareholders,” or the Selling Shareholders, of an aggregate of up to 43,738,900 of our common shares, consisting of: (i) 3,489,486 common shares, par value $0.0001 per share, (ii) 7,986,913 common shares issuable upon exercise of a common share purchase warrant to purchase common shares at an exercise price of $0.70 per common share, and (iii) 32,262,501 common shares issuable upon conversion of certain outstanding convertible promissory notes, at a conversion price of $1.20 per common share.

We are not selling any common shares under this prospectus and will not receive any proceeds from the sale of common shares by the Selling Shareholders. We may receive proceeds from the cash exercise of the common share purchase warrant which, if exercised in cash with respect to all of the 7,986,913 common shares underlying such warrant, would result in gross proceeds of approximately $5,590,839 to us. The Selling Shareholders will bear all commissions and discounts, if any, attributable to the sale of the common shares.

The Selling Shareholders may sell the common shares offered by this prospectus from time to time on terms to be determined at the time of sale through ordinary brokerage transactions or through any other means described in this prospectus under the caption “Plan of Distribution.” The common shares may be sold at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market price or at negotiated prices.

Our common shares are listed on the Nasdaq Capital Market under the symbol “SHIP”. On April 15, 2021, the last reported sale price of our common shares on the Nasdaq Capital Market was $0.9789 per share. During the first quarter of 2021, the trading price of our common shares has increased significantly, which we believe is primarily attributable to the announcement of certain debt restructuring transactions in January 2021, our regaining compliance, on February 11, 2021, with Nasdaq listing rules concerning the minimum bid price of our common stock, and positive developments in the Capesize market, which is our area of operations. On December 31, 2020, the closing price of our common shares on the Nasdaq Capital Market was $0.5376 per share, while on February 16, 2021, the closing price was $2.26. There is a potential for rapid and substantial decreases in the price of our common shares, including decreases unrelated to our operating performance or prospects.

Investing in our securities involves a high degree of risk. See “Risk Factors” below, beginning on page 4, and in our Annual Report on Form 20-F for the year ended December 31, 2020, which is incorporated by reference herein, to read about the risks you should consider before investing in our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is , 2021.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference into this prospectus contain certain forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements regarding our or our management’s expectations, hopes, beliefs, intentions or strategies regarding the future and other statements that are other than statements of historical fact. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking.

The forward-looking statements in this prospectus and the documents incorporated by reference into this prospectus are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in our records and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies that are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs or projections. As a result, you are cautioned not to rely on any forward-looking statements.

Many of these statements are based on our assumptions about factors that are beyond our ability to control or predict and are subject to risks and uncertainties that are described more fully in “Item 3. Key Information—D. Risk Factors” of our Annual Report on Form 20-F for the year ended December 31, 2020, which is incorporated by reference herein. Any of these factors or a combination of these factors could materially affect our future results of operations and the ultimate accuracy of the forward-looking statements. In addition to these important factors and matters discussed elsewhere herein and in the documents incorporated by reference herein, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include, among other things:

•	changes in shipping industry trends, including charter rates, vessel values and factors affecting vessel supply and demand;

•	changes in seaborne and other transportation patterns;

•	changes in the supply of or demand for dry bulk commodities, including dry bulk commodities carried by sea, generally or in particular regions;

•	changes in the number of newbuildings under construction in the dry bulk shipping industry;

•	changes in the useful lives and the value of our vessels and the related impact on our compliance with loan or financing arrangements covenants;

•	the aging of our fleet and increases in operating costs;

•	changes in our ability to complete future, pending or recent acquisitions or dispositions;

•	our ability to achieve successful utilization of our expanded fleet;

•	changes to our financial condition and liquidity, including our ability to pay amounts that we owe and obtain additional financing to fund capital expenditures, acquisitions and other general corporate activities;

•	risks related to our business strategy, areas of possible expansion or expected capital spending or operating expenses;

•	changes in our ability to leverage the relationships and reputation in the dry bulk shipping industry of V.Ships Limited, or V.Ships, and V.Ships Greece Ltd., or V.Ships Greece, our technical managers, and Fidelity Marine Inc., or Fidelity, our commercial manager;

•	changes in the availability of crew, number of off-hire days, classification survey requirements and insurance costs for the vessels in our fleet;

•	changes in our relationships with our contract counterparties, including the failure of any of our contract counterparties to comply with their agreements with us;

iii

TABLE OF CONTENTS

•	loss of our customers, charters or vessels;

•	damage to our vessels;

•	potential liability from future litigation and incidents involving our vessels;

•	our future operating or financial results;

•	acts of terrorism, other hostilities, pandemics or other calamities (including, without limitation, the worldwide novel coronavirus, or COVID-19, outbreak);

•	risks associated with the length and severity of the ongoing COVID-19 outbreak, including its effects on demand for dry bulk products, crew changes and the transportation thereof;

•	changes in global and regional economic and political conditions;

•	changes in governmental rules and regulations or actions taken by regulatory authorities, particularly with respect to the dry bulk shipping industry;

•	our ability to continue as a going concern; and

•

other factors listed from time to time in registration statements, reports or other materials that we have filed with or furnished to the U.S. Securities and Exchange Commission, or the Commission, including our most recent annual report on Form 20-F, which is incorporated by reference into this prospectus.

Should one or more of the foregoing risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable laws. If one or more forward-looking statements are updated, no inference should be drawn that additional updates will be made with respect to those or other forward-looking statements.

TABLE OF CONTENTS

ENFORCEABILITY OF CIVIL LIABILITIES

We are incorporated under the laws of the Republic of the Marshall Islands and our principal executive offices are located outside the United States. Certain of our directors and officers reside outside the United States. In addition, substantially all of our assets and the assets of certain of our directors and officers are located outside the United States. As a result, it may not be possible for you to serve legal process within the United States upon us or any of these persons. It may also not be possible for you to enforce, both in and outside the United States, judgments you may obtain in United States courts against us or these persons in any action, including actions based upon the civil liability provisions of U.S. federal or state securities laws.

Furthermore, there is substantial doubt that courts in jurisdictions outside of the U.S. (i) would enforce judgments of U.S. courts obtained in actions against us or our directors or officers based upon the civil liability provisions of applicable U.S. federal and state securities laws or (ii) would enforce, in original actions, liabilities against us or our directors or officers based on those laws.

This prospectus relates to up to 43,738,900 common shares that the Selling Shareholders may sell in one or more offerings, consisting of: (i) 3,489,486 common shares, par value $0.0001 per share, (ii) 7,986,913 common shares issuable upon exercise of a common share purchase warrant to purchase common shares at an exercise price of $0.70 per common share, and (iii) 32,262,501 common shares issuable upon conversion of certain outstanding convertible promissory notes, at a conversion price of $1.20 per common share.

On December 30, 2020, we entered into definitive documentation for a restructuring transaction with Jelco, pursuant to which all maturities under certain loan facilities and convertible notes provided by Jelco were extended to December 2024 (the “Jelco Restructuring Transactions”). The common shares registered hereunder were issued on January 8, 2021 (or on March 24, 2021 upon the exercise of a pre-funded common share purchase warrant issued on January 8, 2021), or are issuable upon the exercise of a common share purchase warrant held by Jelco issued on January 8, 2021, or upon conversion of convertible notes held by Jelco which were amended on December 31, 2020, in each case in connection with the Jelco Restructuring Transactions. The common shares registered hereunder are being registered for resale pursuant to the registration rights agreement dated December 31, 2020 entered into in connection with the Jelco Restructuring Transactions. For more information on the Jelco Restructuring Transactions, see “Item 5. Operating and Financial Review and Prospects – B. Liquidity and Capital Resources – Loan Arrangements – Jelco Restructuring Transactions” in our annual report on Form 20-F for the fiscal year ended December 31, 2020, incorporated by reference herein.

The registration of these common shares does not mean that the Selling Shareholders will sell or otherwise dispose of all or any of those securities. The Selling Shareholders may sell or otherwise dispose of all, a portion or none of such common shares from time to time. We do not know the number of common shares, if any, that will be offered for sale or other disposition by any of the Selling Shareholders under this prospectus. The Selling Shareholders identified below may in the future hold or acquire our common shares or warrants to purchase our common shares in addition to the securities described herein, subject to the terms of the Securities Purchase Agreement restricting Jelco’s beneficial ownership to 9.99% of our outstanding common shares. In addition, the Selling Shareholders identified below may sell, transfer, assign or otherwise dispose of some or all of the common shares covered hereby in private placement transactions exempt from or not subject to the registration requirements of the Securities Act.

To our knowledge, the Selling Shareholders do not have nor have had within the past three years, any position, office or other material relationship with us or any of our predecessors or affiliates, other than as described in this prospectus and the documents incorporated by reference herein.

The following table sets forth certain information with respect to each Selling Shareholder, including (i) the common shares beneficially owned by the Selling Shareholder prior to this offering, (ii) the number of common shares offered by the Selling Shareholder pursuant to this prospectus and (iii) the Selling Shareholder’s beneficial ownership after completion of this offering, assuming that all of the common shares covered hereby (but none of the other common shares held by the Selling Shareholders) are sold.

We have prepared the following table based on information supplied to us by the Selling Shareholders on or prior to the date hereof, and we have not sought to verify such information. Ownership and percentage ownership are determined in accordance with the rules and regulations of the Commission regarding beneficial ownership and include voting or investment power with respect to common shares. This information does not necessarily indicate beneficial ownership for any other purpose. In computing the number of common shares beneficially owned by a Selling Shareholder and the percentage ownership of that Selling Shareholder, common shares underlying warrants held by that selling stockholder that are exercisable as of the date hereof, or exercisable within 60 days after the date hereof, are deemed outstanding. Such common shares, however, are not deemed outstanding for the purposes of computing the percentage ownership of any other person. The calculation of percentage of beneficial ownership is based on 156,215,613 common shares issued and outstanding as of April 15, 2021. The number of common shares owned prior to this offering and the number of common shares owned following this offering in the table below do not give effect to the beneficial ownership blockers contained in the warrants and convertible notes held by the Selling Shareholders, but the percentages in the table below do give effect to such beneficial ownership blockers.

(2)

Based on 156,215,613 common shares issued and outstanding as of April 15, 2021, and assuming all shares offered hereby underlying warrants and convertible notes are issued, the Selling Shareholder sells all common shares offered pursuant to this prospectus and no common shares are issued pursuant to other outstanding warrants of the Company.

(3)

The common shares beneficially owned by Jelco include (i) 113,970 common shares issuable upon exercise of the Class B Warrants held by Jelco, (ii) 32,262,501 common shares issuable upon conversion of certain convertible promissory notes held by Jelco, (iii) 7,986,913 common shares issuable upon exercise of a common share purchase warrant at an exercise price of $0.70 per common share issued on January 8, 2021, and (iv) 4,285,714 common shares, and 4,285,714 common shares underlying the common share purchase warrant, which Jelco has an option to acquire pursuant to the Securities Purchase Agreement, in each case subject to a 9.99% beneficial ownership blocker. The number of shares owned reported in this paragraph and in the table above do not give effect to such 9.99% beneficial ownership blockers, but the percentages in the table above do give effect to such beneficial ownership blockers.

TABLE OF CONTENTS

PLAN OF DISTRIBUTION

The common shares covered by this prospectus may be offered and sold from time to time by the Selling Shareholders. The term “Selling Shareholder” includes pledgees, donees, transferees or other successors in interest selling shares received after the date of this prospectus from each Selling Shareholder as a pledge, gift, partnership distribution or other sale in any privately negotiated transaction, or non-sale related transfer. The number of shares beneficially owned by a Selling Shareholder may decrease as and when it effects any such transfers. The plan of distribution for the Selling Shareholders’ shares sold hereunder will otherwise remain unchanged, except that the transferees, pledgees, donees or other successors will be Selling Shareholders hereunder. To the extent required, we may amend and supplement this prospectus from time to time to describe a specific plan of distribution.

The Selling Shareholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. The Selling Shareholders may make these sales at prices and under terms then prevailing or at prices related to the then current market price. The Selling Shareholders may also make sales in negotiated transactions. The Selling Shareholders may offer their shares from time to time pursuant to one or more of the following methods:

•	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•	one or more block trades in which the broker-dealer will attempt to sell the common shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•	purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•	an exchange distribution in accordance with the rules of the applicable exchange;

•	public or privately negotiated transactions;

•	on the Nasdaq Capital Market (or through the facilities of any national securities exchange or U.S. inter-dealer quotation system of a registered national securities association, on which the common shares are then listed, admitted to unlisted trading privileges or included for quotation);

•	through underwriters, brokers or dealers (who may act as agents or principals) or directly to one or more purchasers;

•	to cover short sales;

•	a combination of any such methods of sale; and

•	any other method permitted pursuant to applicable law.

In connection with distributions of the common shares or otherwise, the Selling Shareholders may:

•	enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common shares in the course of hedging the positions they assume;

•	sell the common shares short and redeliver the common shares to close out such short positions;

•	enter into option or other transactions with broker-dealers or other financial institutions which require the delivery to them of shares offered by this prospectus, which they may in turn resell; and

•	pledge shares to a broker-dealer or other financial institution, which, upon a default, they may in turn resell.

In addition to the foregoing methods, the Selling Shareholders may offer their shares from time to time in transactions involving principals or brokers not otherwise contemplated above, in a combination of such methods or described above or any other lawful methods. The Selling Shareholders may also transfer, donate or assign their shares to lenders, family members and others and each of such persons will be deemed to be a Selling Shareholder for purposes of this prospectus. The Selling Shareholders or their successors in interest may from time to time pledge or grant a security interest in some or all of the common shares of common stock, and if the Selling Shareholders default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the common shares of common stock from to time under this prospectus; provided however in the event of a pledge or then default on a secured obligation by the Selling Shareholder, in order for the common shares to be sold under this registration statement, unless permitted by law, we must file a prospectus supplement and/or amendment to this registration statement amending the list of Selling Shareholders to include the pledgee, secured party or other successors in interest of the Selling Shareholder under this prospectus.

TABLE OF CONTENTS

The Selling Shareholders may also sell their shares pursuant to Rule 144 under the Securities Act, which permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things, the availability of certain current public information concerning the issuer, the resale occurring following the required holding period under Rule 144 and the number of shares being sold during any three-month period not exceeding certain limitations in certain circumstances.

Sales through brokers may be made by any method of trading authorized by any stock exchange or market on which the common shares may be listed or quoted, including block trading in negotiated transactions. Without limiting the foregoing, such brokers may act as dealers by purchasing any or all of the common shares covered by this prospectus, either as agents for others or as principals for their own accounts, and reselling such shares pursuant to this prospectus. The Selling Shareholders may effect such transactions directly, or indirectly through underwriters, broker-dealers or agents acting on their behalf. In effecting sales, broker-dealers or agents engaged by the Selling Shareholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Shareholders, in amounts to be negotiated immediately prior to the sale (which compensation as to a particular broker-dealer might be in excess of customary commissions for routine market transactions).

In offering the common shares covered by this prospectus, the Selling Shareholders, and any broker-dealers and any other participating broker-dealers who execute sales for the Selling Shareholders, may be deemed to be “underwriters” within the meaning of the Securities Act in connection with these sales. Any profits realized by the Selling Shareholders and the compensation of such broker-dealers may be deemed to be underwriting discounts and commissions.

The Company is required to pay all fees and expenses incident to the registration of the common shares other than broker and underwriter fees and commissions or legal fees or other costs of the Selling Shareholders.

The Company has agreed to indemnify the Selling Shareholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

There can be no assurance that the Selling Shareholders will sell any or all of the common shares registered pursuant to the registration statement, of which this prospectus forms a part.

In order to comply with the securities laws of some states, if applicable, the common shares may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

The Selling Shareholders and any other person participating in a distribution of the common shares covered by this prospectus will be subject to the applicable provisions of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of any of the common shares by the Selling Shareholders and any other such person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the common shares to engage in market-making activities with respect to the common shares.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8.

Indemnification of Directors and Officers

Under Article VII of our third amended and restated bylaws and under Section 60 of the BCA, we may indemnify anyone who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding . However, such person must have acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, such person had no reasonable cause to believe that his conduct was unlawful. Under Section 60 of the BCA and our third amended and restated bylaws, the termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of no contest, or its equivalent, does not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

In addition, under Section 60 of the BCA and under our third amended and restated bylaws, we may indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending, or completed action or suit by or in the right of the corporation to procure judgment in its favor by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. Such indemnification may be made against expenses (including attorneys’ fees) actually and reasonably incurred by such person or in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation. Again, this is provided that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

Furthermore, and as provided by both our third amended and restated bylaws and Section 60 of the BCA, when a director, officer, employee or agent of the corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in the foregoing instances, or in the defense of a related claim, issue or matter, such person will be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred in connection with such matter.

Likewise, pursuant to our third amended and restated bylaws and Section 60 of the BCA, expenses (our third amended and restated bylaws specifically includes attorneys’ fees in expenses) incurred in defending a civil or criminal action, suit or proceeding by an officer or director may be paid in advance of the final disposition of the action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it is ultimately determined that such person is not entitled to indemnification. The third amended and restated bylaws further provide that with respect to other employees and agents, such expenses may be paid on the terms and conditions, if any, as the Board may deem appropriate.

Both Section 60 of the BCA and our third amended and restated bylaws further provide that the foregoing indemnification and advancement of expenses are not exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise, both as to action in any person’s official capacity and/or as to action in another capacity while holding office.

Under both Section 60 of the BCA and our third amended and restated bylaws, we also have the power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another

II-1

TABLE OF CONTENTS

corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in such capacity regardless of whether the corporation would have the power to indemnify such person against such liability under the foregoing.

Under Section 60 of the BCA (and as provided in our third amended and restated bylaws), the indemnification and advancement of expenses provided by, or granted under the foregoing continue with regard to a person who has ceased to be a director, officer, employee or agent and inure to the benefit of such person’s heirs, executors and administrators unless otherwise provided when authorized or ratified. Additionally, under Section 60 of the BCA and our third amended and restated bylaws, any repeal or modification of Article VII of our third amended and restated bylaws shall not adversely affect any rights to indemnification and to the advancement of expenses of a director or officer of the corporation existing at the time of such repeal or modification with respect to any acts or omissions occurring prior to such repeal or modification.

In addition to the above, our third amended and restated bylaws provide that references to us includes constituent corporations, and defines “other enterprises” to include employee benefit plans, “fines” to include excise taxes imposed on a person with respect to an employee benefit plan, and further defines the term “serving at the request of the corporation.”

Such limitation of liability and indemnification does not affect the availability of equitable remedies. In addition, we have been advised that in the opinion of the Commission, indemnification for liabilities arising under the Securities Act is against public policy as expressed in the Securities Act and is therefore unenforceable.

(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 Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, as amended, 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.

II-2

(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)

To file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Act need not be furnished, provided, that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (a)(4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, with respect to registration statements on Form F-3, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act of 1933 Item 8.A of Form 20-F if such financial statements and information are contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Form F-3.

(5)	That, for the purpose of determining liability under the Securities Act of 1933, as amended, to any purchaser;

(i)	Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of this Registration Statement as of the date the filed prospectus was deemed part of and included in this 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 of 1933 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.

(6)

That, for the purpose of determining liability under the Securities Act of 1933, as amended, 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;

TABLE OF CONTENTS

(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) 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)

The undersigned registrant hereby undertakes to supplement the prospectus, after the expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms differing from those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering.

(d)	Not applicable.

(e)

The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report, to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

(f) – (g) Not applicable.

(h)

Insofar as indemnification for liabilities arising under the Securities Act of 1933 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 of 1933 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 of 1933 and will be governed by the final adjudication of such issue.
