(1) Such amount in U.S. dollars or the equivalent thereof in foreign currencies as shall result in an aggregate initial public offering price for all securities of $500,000,000. Also includes such indeterminate amount of debt securities and common shares and preferred shares as may be issued upon conversion or exchange for any other debt securities or preferred shares that provide for conversion or exchange into other securities.

(2) Estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(o) under the Securities Act of 1933. Pursuant to General Instruction II.C of Form F-3, the table does not specify by each class information as to the proposed maximum aggregate offering price. Any securities registered hereunder may be sold separately or as units with other securities registered hereunder. In no event will the aggregate offering price of all securities sold by Nordic American Tankers Ltd. pursuant to this registration statement exceed $500,000,000.

(3) Calculated in accordance with Rule 457(o) under the Securities Act of 1933 using the current fee rate of .0000927.

(4) Preferred share purchase rights are not currently separable from the common shares and are not currently exercisable. The value attributable to the preferred share purchase rights, if any, will be reflected in the market price of the common shares.

(10) As discussed below, pursuant to Rule 457(p) under the Securities Act, this Registration Statement includes unsold securities that had been previously registered and for which the registration fee had previously been paid. Accordingly, the amount of the registration fee to be paid is reduced by the $27,392 amount of the registration fee applied to such unsold securities and equals $18,958.

Pursuant to Rule 457(p) under the Securities Act, the securities registered pursuant to this Registration Statement include unsold securities previously registered under the registration statement on Form F-3 with File No. 333-228603 dated November 30, 2018 (the "Prior Registration Statement"). In connection with the registration of the unsold securities on the Prior Registration Statement, the Registrant paid a registration fee of $27,392, which continues to be applied to such securities and is applied to the total fee associated with this Registration Statement.

This prospectus is not an offer to sell these securities and it is not soliciting an offer to buy or sell these securities in any jurisdiction where the offer or sale is not permitted.

We prepare our financial statements, including all of the financial statements included or incorporated by reference in this prospectus, in U.S. dollars and in conformity with U.S. generally accepted accounting principles, or "U.S. GAAP." We have a fiscal year end of December 31.

This prospectus is part of a registration statement filed with the U.S. Securities and Exchange Commission, or the Commission, using a shelf registration process. Under the shelf registration process, we may sell our common shares (including preferred share purchase rights), preferred shares, debt securities, warrants, purchase contracts and units described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we may offer. Each time we offer securities, we will provide you with a prospectus supplement that will describe the specific amounts, prices and terms of the offered securities. We may file a prospectus supplement in the future that may also add, update or change the information contained in this prospectus. You should read carefully both this prospectus and any prospectus supplement, together with the additional information described below.

This prospectus and any prospectus supplement are part of a registration statement we have filed with the Commission and do not contain all the information in the registration statement. Forms of the indentures and other documents establishing the terms of the offered securities are filed as exhibits to the registration statement. Statements in this prospectus or any prospectus supplement about these documents are summaries and each statement is qualified in all respects by reference to the document to which it refers. You should refer to the actual documents for a more complete description of the relevant matters. For further information about us or the securities offered hereby, you should refer to the registration statement, which you can obtain from the Commission as described below under the section entitled "Where You Can Find Additional Information."

You should rely only on the information contained or incorporated by reference in this prospectus and in any prospectus supplement. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. You should assume that the information appearing in this prospectus and the applicable supplement to this prospectus is accurate as of the date on its respective cover, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates.

Other than in the United States, no action has been taken by us or any underwriters that would permit a public offering of the common shares offered by this prospectus in any jurisdiction where action for that purpose is required. The common shares offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such shares be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus comes are advised to inform themselves about and to observe any restrictions relating to the offering and the distribution of this prospectus. This prospectus does not constitute an offer to sell or a solicitation of an offer to buy any common shares offered by this prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

Common shares may be offered or sold in Bermuda only in compliance with the provisions of the Investment Business Act of 2003 and the Exchange Control Act 1972, and related regulations of Bermuda which regulate the sale of securities in Bermuda. In addition, specific permission is required from the Bermuda Monetary Authority, or the BMA, pursuant to the provisions of the Exchange Control Act 1972 and related regulations, for all issuances and transfers of securities of Bermuda companies, other than in cases where the BMA has granted a general permission. The BMA, in its policy dated June 1, 2005, provides that where any equity securities, including our common shares, of a Bermuda company are listed on an appointed stock exchange, general permission is given for the issue and subsequent transfer of any securities of a company from and/or to a non-resident, for as long as any equities securities of such company remain so listed. The New York Stock Exchange, or the NYSE, is an appointed stock exchange under Bermuda law. Approvals or permissions given by the Bermuda Monetary Authority do not constitute a guarantee by the Bermuda Monetary Authority as to our performance or our creditworthiness. Neither this prospectus nor any prospectus supplement needs to be filed with the Registrar of Companies in Bermuda in accordance with Part III of the Companies Act 1981 of Bermuda pursuant to provisions incorporated therein following the enactment of the Companies Amendment Act 2013. Such provisions state that a prospectus in respect of the offer of shares in a Bermuda company whose equities are listed on an appointed stock exchange under Bermuda law does not need to be filed in Bermuda, so long as the company in question complies with the requirements of such appointed stock exchange in relation thereto.

1

Notwithstanding the above general permission, the BMA has granted the Company permission, subject to the common shares of the Company being listed on an appointed stock exchange, to issue, grant, create, sell and transfer any of the Company's other shares, stock, bonds, notes (other than promissory notes), debentures, debenture stock, units under a unit trust scheme, shares in an oil royalty, options, warrants, coupons, rights and depository receipts, or collectively the Securities, to and among persons who are either resident or non-resident of Bermuda for exchange control purposes, whether or not the Securities are listed on an appointed stock exchange.

Neither the BMA nor the Registrar of Companies accepts any responsibility for our financial soundness or for the correctness of any of the statements made or opinions expressed in this prospectus or any prospectus supplement.

PROSPECTUS SUMMARY

This summary provides an overview of our company and our business. This summary is not complete and does not contain all of the information you should consider before purchasing our securities. You should carefully read all of the information contained or incorporated by reference in this prospectus and any accompanying prospectus supplement, including the "Risk Factors" and our consolidated financial statements and related notes contained herein and therein, before making an investment decision. Unless we specify otherwise, all references in this prospectus to "we," "our," "us" and the "Company" refer to Nordic American Tankers Limited. We use the term deadweight, or "dwt," in describing the size of vessels. Dwt, expressed in metric tons each of which is equivalent to 1,000 kilograms, refers to the maximum weight of cargo and supplies that a vessel can carry.

Our Company

Nordic American Tankers Limited was formed on June 12, 1995 under the name Nordic American Tanker Shipping Limited and organized under the laws of the Islands of Bermuda. In June 2011, we changed our name to Nordic American Tankers Limited. We maintain our principal offices at LOM Building, 27 Reid Street, Hamilton HM 11, Bermuda. Our telephone number at such address is (441) 292-7202 and we maintain an internet site at www.nat.bm. The SEC maintains an Internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. The address of the SEC’s internet site is www.sec.gov. None of the information contained on these websites is incorporated into or forms a part of this annual report. Our common shares trade under the symbol “NAT” on the New York Stock Exchange, or the NYSE.

We are an international tanker company originally formed for the purpose of acquiring and chartering double-hull Suezmax tankers. Our fleet currently consists of 24 vessels (including 2 newbuildings). During 2020, we placed orders for two Suezmax newbuildings from Samsung shipyard in South Korea for delivery in 2022. In November 2021 we sold Nordic Sirius (2000-built).

Our Fleet

Our fleet currently consists of 24 Suezmax crude oil tankers (including 2 newbuildings). The majority of our vessels are employed in the spot market, together with one vessel currently on a longer term time charter agreement expiring in late 2021 or later. The vessels are considered homogenous and interchangeable as they have approximately the same freight capacity and ability to transport the same type of cargo.

The technical management of our vessels is handled by companies under direct instructions from NAT.

The compensation paid under the technical management agreements is in accordance with industry standards.

RISK FACTORS

An investment in our securities involves a high degree of risk.  You should carefully consider the risks set forth below and the discussion of risks under the heading "Item 3. Key Information—D. Risk Factors" in our Annual Report on Form 20-F for the year ended December 31, 2020, as amended, filed with the Commission on April 29, 2021, and the other documents which are incorporated by reference in this prospectus, before making an investment in our securities.  Please see the section of this prospectus entitled "Where You Can Find Additional Information—Information Incorporated by Reference."  In addition, you should also consider carefully the risks set forth under the heading "Risk Factors" in any prospectus supplement before investing in the securities offered by this prospectus. The occurrence of one or more of those risk factors could adversely impact our business, financial condition or results of operations.

We may issue additional common shares or other equity securities without your approval, which would dilute your ownership interests and may depress the market price of our common shares.

We may issue additional common shares or other equity securities of equal or senior rank in the future in connection with, among other things, future vessel acquisitions, repayment of outstanding indebtedness or our equity incentive plan, without shareholder approval, in a number of circumstances.

Our issuance of additional common shares or other equity securities of equal or senior rank would have the following effects:

• our existing shareholders' proportionate ownership interest in us may decrease;

• the amount of cash available for dividends payable on our common shares may decrease;

• the relative voting strength of each previously outstanding common share may be diminished; and

• the market price of our common shares may decline.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain matters discussed herein may constitute forward-looking statements. The Private Securities Litigation Reform Act of 1995 provides safe harbor protections for forward-looking statements in order to encourage companies to provide prospective information about their business. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts.

The Company desires to take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and is including this cautionary statement in connection with this safe harbor legislation. This report and any other written or oral statements made by us or on our behalf may include forward-looking statements, which reflect our current views with respect to future events and financial performance, and are not intended to give any assurance as to future results. When used in this document, the words "believe," "expect," "anticipate," "estimate," "intend," "plan," "target," "project," "likely," "may," "could" and similar expressions, terms, or phrases may identify forward-looking statements.

The forward-looking statements are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, our 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 which 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. We undertake no obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise.

Important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include the strength of world economies and currencies, general market conditions, including fluctuations in charter rates and vessel values, changes in demand in the tanker market, as a result of changes in the petroleum production levels set by the Organization of the Petroleum Exporting Countries, or OPEC, and worldwide oil consumption and storage, changes in our operating expenses, including bunker prices, drydocking and insurance costs, the market for our vessels, availability of financing and refinancing, changes in governmental rules and regulations or actions taken by regulatory authorities, potential liability from pending or future litigation, general domestic and international political conditions, potential disruption of shipping routes due to accidents or political events, vessel breakdowns and instances of off-hire, failure on the part of a seller to complete a sale of a vessel to us and other important factors described from time to time in the reports filed by the Company with the Securities and Exchange Commission, or the SEC.

CAPITALIZATION

Each prospectus supplement will include information on the Company's consolidated capitalization.

9

ENFORCEMENT OF CIVIL LIABILITIES

There is no treaty in force between the United States and Bermuda providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. As a result, whether a United States judgment would be enforceable in Bermuda against us or our directors and officers depends on whether the U.S. court that entered the judgment is recognized by the Bermuda court as having jurisdiction over us or our directors and officers, as determined by reference to Bermuda conflict of law rules. A judgment debt from a U.S. court that is final and for a sum certain based on U.S. federal securities laws will not be enforceable in Bermuda unless the judgment debtor had submitted to the jurisdiction of the U.S. court, and the issue of submission and jurisdiction is a matter of Bermuda (not U.S.) law.

In addition, and irrespective of jurisdictional issues, the Bermuda courts will not enforce a U.S. federal securities law that is either penal or contrary to the public policy of Bermuda. An action brought pursuant to a public or penal law, the purpose of which is the enforcement of a sanction, power or right at the instance of the state in its sovereign capacity, may not be entertained by a Bermuda court to the extent it is contrary to Bermuda public policy. Certain remedies available under the laws of U.S. jurisdictions, including certain remedies under U.S. federal securities laws, may not be available under Bermuda law or enforceable in a Bermuda court, to the extent they are contrary to Bermuda public policy. Further, no claim may be brought in Bermuda against us or our directors and officers in the first instance for violations of U.S. federal securities laws because these laws have no extraterritorial jurisdiction under Bermuda law and do not have force of law in Bermuda. A Bermuda court may, however, impose civil liability on us or our directors and officers if the facts alleged in a complaint constitute or give rise to a cause of action under Bermuda law.

10

PLAN OF DISTRIBUTION

We may sell or distribute the securities included in this prospectus through underwriters, through agents, to dealers, in private transactions, at market prices prevailing at the time of sale, at prices related to the prevailing market prices, or at negotiated prices.

In addition, we may sell some or all of the securities included in this prospectus through:

• a block trade in which a broker-dealer may resell a portion of the block, as principal, in order to facilitate the transaction;

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

• ordinary brokerage transactions and transactions in which a broker solicits purchasers; or

• trading plans entered into by us pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of our securities on the basis of parameters described in such trading plans. 

In addition, we may enter into options or other types of transactions that require us to deliver our securities to a broker-dealer, who will then resell or transfer the securities under this prospectus. We may enter into hedging transactions with respect to our securities. For example, we may:

• enter into transactions involving short sales of our common shares by broker-dealers;

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

• enter into option or other types of transactions that require us to deliver common shares to a broker-dealer, who will then resell or transfer the common shares under this prospectus; or

• loan or pledge the common shares to a broker-dealer, who may sell the loaned shares or, in the event of default, sell the pledged shares.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and, if not identified in this prospectus, will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

Any broker-dealers or other persons acting on our behalf that participate with us in the distribution of the securities, may be deemed to be underwriters, and any commissions received or profit realized by them on the resale of the securities, may be deemed to be underwriting discounts and commissions under the Securities Act of 1933, as amended, or the Securities Act.  As of the date of this prospectus, we are not a party to any agreement, arrangement or understanding between any broker or dealer and us with respect to the offer or sale of the securities pursuant to this prospectus.

At the time that any particular offering of securities is made, to the extent required by the Securities Act, a prospectus supplement will be distributed, setting forth the terms of the offering, including the aggregate number of securities being offered, the purchase price of the securities, the initial offering price of the securities, the names of any underwriters, dealers or agents, any discounts, commissions and other items constituting compensation from us and any discounts, commissions or concessions allowed or re-allowed or paid to dealers. Furthermore, we, our executive officers, our directors and major shareholders may agree, subject to certain exemptions, that for a certain period from the date of the prospectus supplement under which the securities are offered, we and they will not, without the prior written consent of an underwriter, offer, sell, contract to sell, pledge or otherwise dispose of any of our common shares or any securities convertible into or exchangeable for our common shares.  However, an underwriter, in its sole discretion, may release any of the securities subject to these lock-up agreements at any time without notice. We expect an underwriter to exclude from these lock-up agreements securities exercised and/or sold pursuant to trading plans entered into by us pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of our securities on the basis of parameters described in such trading plans.

Underwriters or agents could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an at-the-market offering as defined in Rule 415 promulgated under the Securities Act, which includes sales made directly on or through the NYSE, the existing trading market for our common shares, or sales made to or through a market maker other than on an exchange.

We will bear costs relating to the securities offered and sold under this Registration Statement.

If more than five percent (5%) of the net proceeds of any offering of common shares made under this prospectus will be received by a Financial Industry Regulatory Authority, or FINRA, member participating in the offering or affiliates or associated persons of such a FINRA member, the offering will be conducted in accordance with FINRA Rule 5121.

Memorandum of Association and Bye-Laws

The following description of our share capital summarizes the material terms of our Memorandum of Association and our bye-laws.

Under our Memorandum of Association, as amended, our authorized capital consists of 360,000,000 common shares having a par value of $0.01 per share.

The purposes and powers of the Company include the entering into of any guarantee, contract, indemnity or suretyship and to assure, support, secure, with or without the consideration or benefit, the performance of any obligations of any person or persons; and the borrowing and raising of money in any currency or currencies to secure or discharge any debt or obligation in any manner.

Our bye-laws provide that our Board of Directors shall convene and the Company shall hold annual general meetings of shareholders in accordance with the requirements of the Companies Act at such times and places as the Board shall decide. However, under Bermuda law, a company may by resolution in general meeting, elect to dispense with the holding of an annual general meeting for (a) the year in which it is made and any subsequent year or years; (b) for a specified number of years; or (c) indefinitely.  Our Board of Directors may call special general meetings of shareholders at its discretion or as required by the Companies Act. Under the Companies Act, holders of one-tenth of our issued common shares may call special general meetings.

Under our bye-laws, five days advance notice of an annual general meeting or any special general meeting must be given to each shareholder entitled to vote at that meeting unless, in the case of an annual general meeting, a shorter notice period for such meeting is agreed to by all of the shareholders entitled to vote thereat and, in the case of any other meeting, in accordance with the requirements of the Companies Act a shorter notice period for such meeting is agreed to by at least 95% of the shareholders entitled to vote thereat. Under Bermuda law, accidental failure to give notice will not invalidate proceedings at a meeting. Our Board of Directors may set a record date for the purpose of identifying the persons entitled to receive notice of and vote at a meeting of shareholders at any time before or after the date on which such notice is dispatched.

Our Board of Directors must consist of at least three and no more than 11 directors, or such number in excess thereof as the Board of Directors may from time to time determine by resolution. Our directors are not required to retire because of their age, and our directors are not required to be holders of our common shares. Directors serve for

12

one-year terms, and shall serve until re-elected or until their successors are appointed at the next annual general meeting. Casual vacancies on our Board of Directors may be filled by a majority vote of the then-current directors.

Any director retiring at an annual general meeting will be eligible for reappointment and will retain office until the close of the meeting at which such director retires or (if earlier) until a resolution is passed at that meeting not to fill the vacancy or the resolution to re-appoint such director is put to a vote at the meeting and is lost. If a director's seat is not filled at the annual general meeting at which he or she retires, such director shall be deemed to have been reappointed unless it is resolved by the shareholders not to fill the vacancy or a resolution for the reappointment of the director is voted upon and lost. No person other than a director retiring shall be appointed a director at any general meeting unless (i) he or she is recommended by the Board of Directors or (ii) a notice executed by a shareholder (not being the person to be proposed) has been received by our secretary no less than 120 days and no more than 150 days prior to the date our proxy statement is released to shareholders in connection with the prior year's annual general meeting declaring the intention to propose an individual for the vacant directorship position.

A director may at any time summon a meeting of the Board of Directors. The quorum necessary for the transaction of business at a meeting of the Board of Directors may be fixed by the Board of Directors and, unless so fixed at any other number, shall be two directors. Questions arising at any meeting of the Board of Directors shall be determined by a majority of the votes cast.

Our bye-laws do not prohibit a director from being a party to, or otherwise having an interest in, any transaction or arrangement with the Company or in which the Company is otherwise interested. Our bye-laws provide that a director who has an interest in any transaction or arrangement with the Company and who has complied with the provisions of the Companies Act and with our bye-laws with regard to disclosure of such interest shall be taken into account in ascertaining whether a quorum is present, and will be entitled to vote in respect of any transaction or arrangement in which he is so interested.

Our bye-laws permit us to increase our authorized share capital with the approval of a majority of votes cast in respect of our outstanding common shares represented in person or by proxy.

There are no pre-emptive, redemption, conversion or sinking fund rights attached to our common shares. The holders of common shares are entitled to one vote per share on all matters submitted to a vote of holders of common shares. Unless a different majority is required by law or by our bye-laws, resolutions to be approved by holders of common shares require approval by a simple majority of votes cast at a meeting at which a quorum is present. Shareholders present in person or by proxy and entitled to vote at a meeting of shareholders representing the holders of at least one-third of the issued shares entitled to vote at such general meeting shall be a quorum for all purposes.

Under our bye-laws, our Board of Directors is authorized to attach to our undesignated shares such preferred, qualified or other special rights, privileges, conditions and restrictions as the Board of Directors may determine. The Board of Directors may allot our undesignated shares in more than one series and attach particular rights and restrictions to any such shares by resolution; provided, however, that the Board of Directors may not attach any rights or restrictions to our undesignated shares that would alter or abrogate any of the special rights attached to any other class or series of shares without such sanction as is required for any such alternation or abrogation unless expressly authorized to do so by the rights attaching to or by the terms of the issue of such shares.

Subject to Bermuda law, special rights attaching to any class of our shares may be altered or abrogated with the consent in writing of not less than 75% of the issued shares of that class or with the sanction of a resolution of the holders of such shares voting in person or by proxy.

In the event of our liquidation, dissolution or winding up, the holders of common shares are entitled to share in our assets, if any, remaining after the payment of all of our debts and liabilities, subject to any liquidation preference on any outstanding preference shares.

Our bye-laws provide that our Board of Directors may, from time to time, subject to compliance with the provisions of the Companies Act, declare and pay dividends or distributions out of contributed surplus, which we refer to collectively as dividends. Each common share is entitled to dividends if and when dividends are declared by our Board of Directors, subject to any preferred dividend right of the holders of any preference shares.

13

There are no limitations on the right of non-Bermudians or non-residents of Bermuda to hold or vote our common shares.

Bermuda law permits the bye-laws of a Bermuda company to contain a provision indemnifying the Company's directors and officers for any loss arising or liability attaching to him or her by virtue of any rule of law in respect of any negligence, default, breach of duty or breach of trust of which the officer or person may be guilty, save with respect to fraud or dishonesty. Bermuda law also grants companies the power generally to indemnify directors and officers of a company, except in instances of fraud and dishonesty, if any such person was or is a party or threatened to be made a party to a threatened, pending or completed action, suit or proceeding by reason of the fact that he or she is or was a director and officer of such company or was serving in a similar capacity for another entity at such company's request.

Our bye-laws provide that each director, alternate director, officer, person or member of a committee, if any, resident representative, and any liquidator, manager or trustee for the time being acting in relation to the affairs of the Company, and his heirs, executors or administrators, which we refer to collectively as an indemnitee, will be indemnified and held harmless out of our assets to the fullest extent permitted by Bermuda law against all liabilities, loss, damage or expense (including, but not limited to, liabilities under contract, tort and statute or any applicable foreign law or regulation and all reasonable legal and other costs and expenses properly payable) incurred or suffered by him or by reason of any act done, conceived in or omitted in the conduct of the Company's business or in the discharge of his duties except in respect of fraud or dishonesty. In addition, each indemnitee shall be indemnified out of the assets of the Company against all liabilities incurred in defending any proceedings, whether civil or criminal, in which judgment is given in such indemnitee's favor, or in which he is acquitted.

Under our bye-laws, we and our shareholders have agreed to waive any claim or right of action we or they may have at any time against any indemnitee on account of any action taken by such indemnitee or the failure of such indemnitee to take any action in the performance of his duties with or for the Company with the exception of any claims or rights of action arising out of fraud or actions to recover any gain, personal profit or advantage to which such indemnitee is not legally entitled.

Our Board of Directors may, at its discretion, purchase and maintain insurance for, among other persons, any indemnitee or any persons who are or were at the time directors, officers or employees of the Company, or of any other company in which the Company has a direct or indirect interest that is allied or associated with the Company, or of any subsidiary undertaking of the Company or such other company, against liability incurred by such persons in respect of any act or omission in the actual or purported execution or discharge of their duties or in the exercise or purported exercise of their powers or otherwise in relation to their duties, powers or offices in relation to the Company, subsidiary undertaking or any such other company.

Our Memorandum of Association may be amended with the approval of a majority of votes cast in respect of our outstanding common shares represented in person or by proxy and our bye-laws may be amended by approval by not less than 75% of the votes cast in respect of our issued and outstanding common shares represented in person or by proxy.

Dividend Reinvestment and Direct Stock Purchase Plan

We have a Dividend Reinvestment and Direct Stock Purchase Plan allowing existing shareholders to purchase additional common shares by reinvesting all or a portion of the dividends paid on their common shares. We currently do not have an effective registration statement relating to the plan and cannot offer initial investments into the Company or accept any cash investments through the plan.

Description of Preferred Shares

Under our amended and restated bye-laws, our Board is authorized to attach to our undesignated shares such preferred, qualified or other special rights, privileges, conditions and restrictions as the Board may determine, with respect to, among other things, dividends, conversion, voting, redemption, liquidation and the number of shares constituting any series. The Board may allot our undesignated shares in more than one series and attach particular rights and restrictions to any such shares by resolution; provided, however, that the Board may not attach any rights or restrictions to our undesignated shares that would alter or abrogate any of the special rights attached to any other

14

class or series of shares without such sanction as is required for any such alteration or abrogation unless expressly authorized to do so by the rights attaching to or by the terms of the issue of such shares. The issuance of preferred shares may have the effect of delaying, deferring or preventing a change in control of the Company without further action by the shareholders. The issuance of preferred shares with voting and conversion rights may adversely affect the voting power of the holders of common shares.

The material terms of any series of preferred shares that we offer through a prospectus supplement will be described in that prospectus supplement.

Transfer Agent

The registrar and transfer agent for our common shares is Computershare Shareowner Services LLC.

Listing

Our common shares are listed on the NYSE under the symbol "NAT."

DESCRIPTION OF DEBT SECURITIES

We may offer and issue debt securities from time to time in one or more series, under one or more indentures, each dated as of a date on or prior to the issuance of the debt securities to which it relates, and pursuant to an applicable prospectus supplement.  We may issue senior debt securities and subordinated debt securities pursuant to separate indentures, a senior indenture and a subordinated indenture, respectively, in each case between us and the trustee named in the indenture.  We have filed forms of these documents as exhibits to the registration statement, of which this prospectus forms a part.  The senior indenture and the subordinated indenture, as amended or supplemented from time to time, are sometimes referred to individually as an "indenture" and collectively as the "indentures." Each indenture will be subject to and governed by the Trust Indenture Act and will be construed in accordance with and governed by the laws of the State of New York, without giving effect to any principles thereof relating to conflicts of law that would result in the application of the laws of any other jurisdiction, unless otherwise stated in the applicable prospectus supplement and indenture (or post-effective amendment hereto).  The aggregate principal amount of debt securities which may be issued under each indenture will contain the specific terms of any series of debt securities or provide that those terms must be set forth in or determined pursuant to, an authorizing resolution, as defined in the applicable prospectus supplement, and/or a supplemental indenture, if any, relating to such series.  Our debt securities may be convertible or exchangeable into any of our equity or other debt securities.

The following description sets forth certain general terms and provisions of the debt securities. The particular terms and provisions of the debt securities offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply to the offered debt securities, will be described in the applicable subsequent filings.  We refer to any applicable prospectus supplement, amendment to the registration statement of which this prospectus forms a part, and reports we file with the Commission under the Exchange Act as "subsequent filings."  The statements below are not complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the applicable indenture. The specific terms of any debt securities that we may offer, including any modifications of, or additions to, the general terms described below as well as any applicable material U.S. federal income tax considerations concerning the ownership of such debt securities will be described in the applicable prospectus supplement and indenture and, as applicable, supplemental indenture. Accordingly, for a complete description of the terms of a particular issue of debt securities, the general description of the debt securities set forth below should be read in conjunction with the applicable prospectus supplement and indenture, as amended or supplemented from time to time.

General

We expect that neither indenture will limit the amount of debt securities which may be issued.  The debt securities may be issued in one or more series.

You should read the applicable indenture and subsequent filings relating to the particular series of debt securities for the following terms of the offered debt securities:

• the designation, aggregate principal amount and authorized denominations;

• the issue price, expressed as a percentage of the aggregate principal amount;

• the maturity date;

• the interest rate per annum, if any;

• if the debt securities provide for interest payments, the date from which interest will accrue, the dates on which interest will be payable, the date on which payment of interest will commence and the regular record dates for interest payment dates;

• any optional or mandatory sinking fund provisions or exchangeability provisions;

• the terms and conditions upon which conversion of any convertible debt securities may be effected, including the conversion price, the conversion period and other conversion provisions;

16

• whether the debt securities will be our senior or subordinated securities;

• whether the debt securities will be our secured or unsecured obligations;

• the applicability and terms of any guarantees;

• the date, if any, after which and the price or prices at which the debt securities may be optionally redeemed or must be mandatorily redeemed and any other terms and provisions of optional or mandatory redemptions;

• if other than denominations of $1,000 and any integral multiple thereof, the denominations in which the debt securities of the series will be issuable;

• if other than the full principal amount, the portion of the principal amount of the debt securities of the series which will be payable upon acceleration or provable in bankruptcy;

• any events of default not set forth in this prospectus;

• the currency or currencies, including composite currencies, in which principal, premium and interest will be payable, if other than the currency of the United States of America;

• if principal, premium or interest is payable, at our election or at the election of any holder, in a currency other than that in which the debt securities of the series are stated to be payable, the period or periods within which, and the terms and conditions upon which, the election may be made;

• whether interest will be payable in cash or additional securities at our or the holder's option and the terms and conditions upon which the election may be made;

• if denominated in a currency or currencies other than the currency of the United States of America, the equivalent price in the currency of the United States of America for purposes of determining the voting rights of holders of those debt securities under the applicable indenture;

• if the amount of payments of principal, premium or interest may be determined with reference to an index, formula or other method based on a coin or currency other than that in which the debt securities of the series are stated to be payable, the manner in which the amounts will be determined;

• any restrictive covenants or other material terms relating to the debt securities;

• whether the debt securities will be issued in the form of global securities or certificates in registered form;

• any listing on any securities exchange or quotation system;

• additional provisions, if any, related to defeasance and discharge of the debt securities; and

• any other special features of the debt securities. 

Subsequent filings may include additional terms not listed above.  Unless otherwise indicated in subsequent filings with the Commission relating to the indenture, principal, premium and interest will be payable and the debt securities will be transferable at the corporate trust office of the applicable trustee.  Unless other arrangements are made or set forth in subsequent filings or a supplemental indenture, principal, premium and interest will be paid by checks mailed to the registered holders at their registered addresses.

Unless otherwise indicated in subsequent filings with the Commission, the debt securities will be issued only in fully registered form without coupons, in denominations of $1,000 or any integral multiple thereof.  No service charge will be made for any transfer or exchange of the debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with these debt securities.

17

Some or all of the debt securities may be issued as discounted debt securities, bearing no interest or interest at a rate which at the time of issuance is below market rates, to be sold at a substantial discount below the stated principal amount.  United States federal income tax consequences and other special considerations applicable to any discounted securities will be described in subsequent filings with the Commission relating to those securities.

Senior Debt

We may issue senior debt securities, which may be secured or unsecured, under the senior debt indenture. The senior debt securities will rank on an equal basis with all our other senior debt except subordinated debt.  The senior debt securities will be effectively subordinated, however, to all of our secured debt to the extent of the value of the collateral securing such debt. We will disclose the amount of our debt in the prospectus supplement.

Subordinated Debt

We may issue subordinated debt securities under a subordinated debt indenture.  Subordinated debt would rank subordinate and junior in right of payment, to the extent set forth in the subordinated debt indenture, to all our senior debt.

Covenants

Any series of debt securities may have covenants in addition to or differing from those included in the applicable indenture which will be described in subsequent filings prepared in connection with the offering of such securities, limiting or restricting, among other things:

• our ability to incur either secured or unsecured debt, or both;

• our ability to make certain payments, dividends, redemptions or repurchases;

• our ability to create dividend and other payment restrictions affecting our subsidiaries;

• our ability to make investments;

• mergers and consolidations by us or our subsidiaries;

• sales of assets by us;

• our ability to enter into transactions with affiliates;

• our ability to incur liens; and

• sale and leaseback transactions. 

Modification of the Indentures

We expect that each indenture and the rights of the respective holders may be modified by us only with the consent of holders of not less than a majority in aggregate principal amount of the outstanding debt securities of all series under the respective indenture affected by the modification, taken together as a class.  But we expect that no modification that:

(1) changes the amount of securities whose holders must consent to an amendment, supplement or waiver;

(2) reduces the rate of or changes the interest payment time on any security or alters its redemption provisions (other than any alteration to any such section which would not materially adversely affect the legal rights of any holder under the indenture) or the price at which we are required to offer to purchase the securities;

18

(3) reduces the principal or changes the maturity of any security or reduces the amount of, or postpones the date fixed for, the payment of any sinking fund or analogous obligation;

(4) waives a default or event of default in the payment of the principal of or interest, if any, on any security (except a rescission of acceleration of the securities of any series by the holders of at least a majority in principal amount of the outstanding securities of that series and a waiver of the payment default that resulted from such acceleration);

(5) makes the principal of or interest, if any, on any security payable in any currency other than that stated in the security;

(6) makes any change with respect to holders' rights to receive principal and interest, the terms pursuant to which defaults can be waived, certain modifications affecting shareholders or certain currency-related issues; or

(7) waives a redemption payment with respect to any security or changes any of the provisions with respect to the redemption of any securities;

(8) will be effective against any holder without his consent.  Other terms as specified in subsequent filings may be modified without the consent of the holders.

Events of Default

We expect that each indenture will define an event of default for the debt securities of any series as being any one of the following events:

• default in any payment of interest when due which continues for 30 days;

• default in any payment of principal or premium at maturity;

• default in the deposit of any sinking fund payment when due;

• default in the performance of any covenant in the debt securities or the applicable indenture which

• continues for 60 days after we receive notice of the default;

• default under a bond, debenture, note or other evidence of indebtedness for borrowed money by us or our subsidiaries (to the extent we are directly responsible or liable therefor) having a principal amount in excess of a minimum amount set forth in the applicable subsequent filings, whether such indebtedness now exists or is hereafter created, which default shall have resulted in such indebtedness becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable, without such acceleration having been rescinded or annulled or cured within 30 days after we receive notice of the default; and

• events of bankruptcy, insolvency or reorganization. 

An event of default of one series of debt securities will not necessarily constitute an event of default with respect to any other series of debt securities.

There may be such other or different events of default as described in an applicable subsequent filing with respect to any class or series of debt securities.

We expect that under each indenture, in case an event of default occurs and continues for the debt securities of any series, the applicable trustee or the holders of not less than 25% in aggregate principal amount of the debt securities then outstanding of that series may declare the principal and accrued but unpaid interest of the debt securities of that series to be due and payable.  Further, any event of default for the debt securities of any series which has been cured is expected to be permitted to be waived by the holders of a majority in aggregate principal amount of the debt securities of that series then outstanding.

19

We expect that each indenture will require us to file annually after debt securities are issued under that indenture with the applicable trustee a written statement signed by two of our officers as to the absence of material defaults under the terms of that indenture.  We also expect that each indenture will provide that the applicable trustee may withhold notice to the holders of any default if it considers it in the interest of the holders to do so, except notice of a default in payment of principal, premium or interest.

Subject to the duties of the trustee in case an event of default occurs and continues, we expect that each indenture will provide that the trustee is under no obligation to exercise any of its rights or powers under that indenture at the request, order or direction of holders unless the holders have offered to the trustee reasonable indemnity.  Subject to these provisions for indemnification and the rights of the trustee, each indenture is expected to provide that the holders of a majority in principal amount of the debt securities of any series then outstanding have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee as long as the exercise of that right does not conflict with any law or the indenture.

Defeasance and Discharge

The terms of each indenture are expected to provide us with the option to be discharged from any and all obligations in respect of the debt securities issued thereunder upon the deposit with the trustee, in trust, of money or U.S. government obligations, or both, which through the payment of interest and principal in accordance with their terms will provide money in an amount sufficient to pay any installment of principal, premium and interest on, and any mandatory sinking fund payments in respect of, the debt securities on the stated maturity of the payments in accordance with the terms of the debt securities and the indenture governing the debt securities.  We expect that this right may only be exercised if, among other things, we have received from, or there has been published by, the United States Internal Revenue Service a ruling to the effect that such a discharge will not be deemed, or result in, a taxable event with respect to holders.  This discharge would not apply to our obligations to register the transfer or exchange of debt securities, to replace stolen, lost or mutilated debt securities, to maintain paying agencies and hold moneys for payment in trust.

Defeasance of Certain Covenants

We expect that the terms of the debt securities provide us with the right not to comply with specified covenants and that specified events of default described in a subsequent filing will not apply provided we deposit with the trustee money or U.S. government obligations, or both, which through the payment of interest and principal will provide money in an amount sufficient to pay any installment of principal, premium, and interest on, and any mandatory sinking fund payments in respect of, the debt securities on the stated maturity of such payments in accordance with the terms of the debt securities and the indenture governing such debt securities. We expect that to exercise this right, we will also be required to deliver to the trustee an opinion of counsel to the effect that the deposit and related covenant defeasance should not cause the holders of such series to recognize income, gain or loss for federal income tax purposes.

We refer you to applicable subsequent filings with respect to any deletions or additions or modifications from the description contained in this prospectus.

Form of Debt Securities

Each debt security will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Both certificated securities in definitive form and global securities may be issued either in registered form, where our obligation runs to the holder of the security named on the face of the security, or in bearer form, where our obligation runs to the bearer of the security.

Definitive securities name you or your nominee as the owner of the security, other than definitive bearer securities, which name the bearer as owner, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable.

20

Global securities name a depositary or its nominee as the owner of the debt securities represented by these global securities, other than global bearer securities, which name the bearer as owner. The depositary maintains a computerized system that will reflect each investor's beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Global Securities

We may issue the debt securities in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees. If not described below, any specific terms of the depositary arrangement with respect to any debt securities to be represented by a registered global security will be described in the prospectus supplement relating to those debt securities. We anticipate that the following provisions will apply to all depositary arrangements:

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants' accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or selling agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some jurisdictions may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities. So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the indenture.

Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the indenture. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest in that registered global security, to exercise any rights of a holder under the indenture. We understand that under existing industry practices, if we request any action of holders of a registered global security or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the indenture, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustee or any other agent of us or agent of the trustee will have any responsibility or liability to owners of beneficial interests for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests. We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants' accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed

21

by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of those participants.

We expect that the indenture will provide that if the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will be required to issue securities in definitive form in exchange for the registered global security that had been held by the depositary. In addition, the indenture is expected to allow us to decide, at any time and in our sole discretion, to not have any of the securities represented by one or more registered global securities. If we make that decision, we will issue securities in definitive form in exchange for all of the registered global security or securities representing those securities. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee or other relevant agent of ours or theirs. It is expected that the depositary's instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

If we issue registered global securities, we expect that the Depository Trust Company, or DTC, will act as depository and the securities will be registered in the name of Cede & Co., as DTC's nominee.

22

DESCRIPTION OF WARRANTS

We may issue warrants to purchase any of our debt or equity securities. Warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants to be issued and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement. We expect that such terms will include, among others:

• the title of such warrants;

• the aggregate number of such warrants;

• the price or prices at which such warrants will be issued;

• the number and type of our securities purchasable upon exercise of such warrants;

• the price at which our securities purchasable upon exercise of such warrants may be purchased;

• the date on which the right to exercise such warrants shall commence and the date on which such right shall expire;

• if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time;

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of any of our debt or equity securities issued by us.

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the securities otherwise deliverable, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities and any acceleration, cancellation or termination provisions, provisions relating to U.S. federal income tax considerations, if any, or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or pre-funded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under either the senior indenture or the subordinated indenture.

24

DESCRIPTION OF RIGHTS

We may issue rights to purchase our equity securities. These rights may be issued independently or together with any other security offered by this prospectus and may or may not be transferable by the shareholder receiving the rights in the rights offering. In connection with any rights offering, we may enter into a standby underwriting agreement with one or more underwriters pursuant to which the underwriter will purchase any securities that remain unsubscribed for upon completion of the rights offering.

The applicable prospectus supplement relating to any rights will describe the terms of the offered rights, including, where applicable, the following:

• the exercise price for the rights;

• the number of rights issued to each shareholder;

• the extent to which the rights are transferable;

• any other terms of the rights, including terms, procedures and limitations relating to the exchange and exercise of the rights;

• the date on which the right to exercise the rights will commence and the date on which the right will expire;

• the amount of rights outstanding;

• the extent to which the rights include an over-subscription privilege with respect to unsubscribed securities; and

• the material terms of any standby underwriting arrangement entered into by us in connection with the rights offering. 

The description in the applicable prospectus supplement of any rights we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable rights certificate or rights agreement, which will be filed with the Commission if we offer rights. For more information on how you can obtain copies of any rights certificate or rights agreement if we offer rights, see the section entitled "Where You Can Find Additional Information" of this prospectus. We urge you to read the applicable rights certificate, the applicable rights agreement and any applicable prospectus supplement in their entirety.

25

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, we may issue units consisting of one or more rights, purchase contracts, warrants, debt securities, preferred shares, common shares or any combination of such securities.  The applicable prospectus supplement will describe the terms of the offered units.  We expect that such terms will include, among others:

• the terms of the units and of the rights, purchase contracts, warrants, debt securities, preferred shares and common shares comprising the units, including whether and under what circumstances the securities comprising the units may be traded separately;

• a description of the terms of any unit agreement governing the units;

• if applicable, a discussion of any material U.S. federal income tax considerations; and

• a description of the provisions for the payment, settlement, transfer or exchange of the units.

In addition, as a "foreign private issuer," we are exempt from the rules under the Exchange Act relating to short swing profit reporting and liability.

Disclosure of Commission Position on Indemnification for Securities Act Liabilities

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable.

31

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 8.Indemnification of Directors and Officers

The Amended and Restated Bye-Laws of the Registrant provide that:

Subject to the proviso below, every director, officer of the Company, inter alia, and member of a committee duly constituted under the Company's Bye-Laws (collectively the "Indemnified Person") shall be indemnified and held harmless out of the assets of the Company against all liabilities, loss, damage or expense (including but not limited to liabilities under contract, tort and statute or any applicable foreign law or regulation and all reasonable legal and other costs and expenses properly payable) incurred or suffered by him by or by reason of any act done, conceived in or omitted in the conduct of the Company's business or in the discharge of his duties and the indemnity contained in this Bye-Law shall extend to any Indemnified Person acting in any office or trust in the reasonable belief that he has been appointed or elected to such office or trust notwithstanding any defect in such appointment or election PROVIDED ALWAYS that the indemnity contained in this Bye-Law shall not extend to any matter which would render it void pursuant to the Companies Acts.

• No Indemnified Person shall be liable to the Company for the acts, defaults or omissions of any other Indemnified Person.

• Every Indemnified Person shall be indemnified out of the assets of the Company against all liabilities incurred by him by or by reason of any act done, conceived in or omitted in the conduct of the Company's business or in the discharge of his duties, in defending any proceedings, whether civil or criminal, in which judgement is given in his favour, or in which he is acquitted, or in connection with any application under the Companies Acts in which relief from liability is granted to him by the court.

• To the extent that any Indemnified Person is entitled to claim an indemnity pursuant to these Bye-Laws in respect of amounts paid or discharged by him, the relevant indemnity shall take effect as an obligation of the Company to reimburse the person making such payment or effecting such discharge.

• Each Shareholder and the Company agree to waive any claim or right of action he or it may at any time have, whether individually or by or in the right of the Company, against any Indemnified Person on account of any action taken by such Indemnified Person or the failure of such Indemnified Person to take any action in the performance of his duties with or for the Company PROVIDED HOWEVER that such waiver shall not apply to any claims or rights of action arising out of the fraud of such Indemnified Person or to recover any gain, personal profit or advantage to which such Indemnified Person is not legally entitled.

• Expenses incurred in defending any civil or criminal action or proceeding for which indemnification is required pursuant to these Bye-Laws shall be paid by the Company in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of the Indemnified Person to repay such amount if any allegation of fraud or dishonesty is proved against the Indemnified Person PROVIDED THAT no monies shall be paid hereunder unless payment of the same shall be authorised in the specific case upon a determination that indemnification of the Director or Officer would be proper in the circumstances because he has met the standard of conduct which would entitle him to the indemnification thereby provided and such determination shall be made:

• by the Board, by a majority vote at a meeting duly constituted by a quorum of Directors not party to the proceedings or matter with regard to which the indemnification is, or would be, claimed; or

• in the case such a meeting cannot be constituted by lack of a disinterested quorum, by independent legal counsel in a written opinion; or

II-1

• by a majority vote of the Shareholders. 

The Companies Act provides as follows:

Section 98 of the Companies Act permits the Bye-Laws of a Bermuda company to contain a provision eliminating personal liability of an officer to the company for any loss arising or liability attaching to him by virtue of any rule of law in respect of any negligence, default, breach of duty or breach of trust of which the officer or person may be guilty, save with respect to fraud or dishonesty;

Section 98 of the Companies Act also grants companies the power generally to indemnify any such officer or auditor of the company against any liability incurred by him in defending any proceedings, whether civil or criminal in which judgment is given in his favor (or in which he is acquitted) or when relief is granted to him by a court under section 281 of the Companies Act;

Section 98A of the Companies Act permits a company to purchase and maintain insurance for the benefit of any officer of the company against any liability incurred by him under section 97(1)(b) of the Companies Act, in his capacity as an officer of the company or indemnifying such an officer in respect of any loss arising or liability attaching to him by virtue of any rule of law in respect of any negligence, default, breach of duty or breach of trust of which the officer may be guilty.

The exhibit index at the end of this registration statement, or the Exhibit Index, identifies the exhibits which are included in this registration statement and are incorporated herein by reference.

Item 10.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 of 1933;

(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 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement.

(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 paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in 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 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 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.

(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.

II-2

(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 or Rule 3-19 of Regulation S-X 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 to any purchaser:

(i) If the registrant is relying on Rule 430B:

(A) 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

(B) 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 314 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 of the Registrant under the Securities Act of 1933 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 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

II-3

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) — (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 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 Act and will be governed by the final adjudication of such issue.

(i) Not applicable.

(j) The undersigned 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 Commission under Section 305(b)(2) of the Trust Indenture Act.

(k) — (l) Not applicable.
