S-3

RISK FACTORS

Any investment in our common shares involves a high degree of risk. In addition to the risk factors described below, you should consider carefully the risk factors beginning on page 4 of our annual report on Form 20-F for the year ended December 31, 2006 and the discussion of risk factors under “Risk Factors” beginning on page 4 of the accompanying base prospectus, as well as the other information contained in this prospectus supplement, the accompanying base prospectus and the documents we have incorporated by reference in this document, before making an investment in our common shares. Any of the risk factors described in our annual report on Form 20-F or the risk factors described under “Risk Factors” beginning on page 4 of the accompanying base prospectus could significantly and negatively affect our business, financial condition or operating results, which may reduce our ability to pay dividends and lower the trading price of our common shares. You may lose all or part of your investment.

We will be required to make substantial capital expenditures to complete the acquisition of our fleet that we have contracted to purchase and to expand the size of our fleet, which may cause our ability to pay dividends to be diminished, our financial leverage to increase or our shareholders to be diluted.

We have agreed to purchase an additional 26 containerships, incrementally over approximately the next 39 months, at a total purchase price of $1.9 billion, of which $1.6 billion remains outstanding. Our obligation to purchase these additional 26 vessels is not conditional upon our ability to obtain financing for such purchase. To fund the remaining portion of these and other capital expenditures, we will use cash from operations or incur borrowings or raise capital through the sale of additional securities. Use of cash from operations may reduce cash available for dividends to our shareholders. Our ability to obtain bank financing or to access the capital markets for future offerings may be limited by our financial condition at the time of any such financing or offering and the covenants in our existing debt agreements, as well as by adverse market conditions resulting from, among other things, general economic conditions and contingencies and uncertainties that are beyond our control. Our failure to obtain the funds for necessary future capital expenditures could have a material adverse effect on our business, results of operations, financial condition and ability to pay dividends. Even if we are successful in obtaining the necessary funds, the terms of such financings could limit our ability to pay dividends to our shareholders. In addition, incurring additional debt may significantly increase our interest expense and financial leverage, and issuing additional equity securities may result in significant shareholder dilution and would increase the aggregate amount of cash required to distribute a consistent level of dividends from earnings to our shareholders, which could have a material adverse effect on our ability to pay dividends.

We cannot assure you that we will be able to borrow amounts under our credit facilities and restrictive covenants in our credit facilities will impose financial and other restrictions on us, including our ability to pay dividends.

On May 11, 2007, we amended and restated our $1.0 billion credit facility dated August 8, 2005. The amended and restated credit agreement provides for a $1.3 billion single-tranche senior secured seven-year revolving credit facility, of which we have drawn $946.2 million to date. There are restrictions on the amount that can be advanced to us under the $1.3 billion credit facility based on the market value of the vessel or vessels in respect of which the advance is being made. Our $1.3 billion credit facility has a maturity date of May 11, 2014, except that we have the option to extend the facility maturity for an additional year under certain circumstances.

We have also entered into a $365.0 million secured revolving credit facility to complete the acquisition of the two 3500 TEU vessels and the eight 2500 TEU vessels. To date, we have drawn $91.8 million on this facility. The $365.0 million credit facility has a maturity date of (a) for the 2500 TEU vessels, the earlier of (i) the tenth anniversary of the delivery of the final 2500 TEU vessel or (ii) August 31, 2019, or (b) for the 3500 TEU vessels, the earlier of (i) the tenth anniversary of the delivery of the second 3500 TEU vessel or (ii) July 31, 2017.

We have entered into a credit facility for $218.4 million to partially finance the construction of the four 5100 TEU vessels. The facility maturity date is earlier of (a) the anniversary date falling twelve years after the

S-4

scheduled delivery date of the fourth 5100 TEU vessel delivered or (b) December 23, 2021. To date, we have drawn $81.5 million under this credit facility.

We have entered into a $920.0 million reducing revolving credit facility to complete the acquisition of two 2500 TEU vessels, four 4250 TEU vessels and eight 8500 TEU vessels. The facility maturity date is earlier of (a) the anniversary date falling twelve years after the scheduled delivery date of the last vessel covered by the credit facility delivered or (b) December 23, 2022. To date, we have not drawn any amount under this credit facility.

Prior to each drawdown under our credit facilities, we are required, among other things, to meet specified financial ratios and other requirements. To the extent that we are not able to satisfy these requirements, we may not be able to draw down under our credit facilities. We may be required to prepay amounts borrowed under our credit facilities if we, or in certain circumstances, our charterers, experience a change of control.

Our credit facilities also impose operating and financial restrictions on us and require us to comply with certain financial covenants. These restrictions and covenants limit our ability to, among other things:

•

pay dividends if an event of default has occurred and is continuing under one of our credit facilities or if the payment of the dividend would result in an event of default;

•

incur additional indebtedness, including through the issuance of guarantees;

•

change the flag, class or management of our vessels;

•

create liens on our assets;

•

sell our vessels without replacing such vessels or prepaying a portion of our loan;

•

conduct material transactions with our affiliates except on an arm’s-length basis;

•

merge or consolidate with, or transfer all or substantially all our assets to, another person; or

•

change our business.

Therefore, we may need to seek permission from our lenders in order to engage in some corporate actions. Our lenders’ interests may be different from ours and we cannot guarantee that we will be able to obtain our lenders’ consent when needed. If we do not comply with the restrictions and covenants in our credit agreements, we will not be able to pay dividends to you, finance our future operations, make acquisitions or pursue business opportunities.

ENVIRONMENTAL AND OTHER REGULATIONS

Canada

The Canada Shipping Act, 2001

On July 1, 2001, the Canada Shipping Act, 2001, or CSA 2001, replaced the Canada Shipping Act as the primary legislation governing marine transport, pollution and safety. However, most of the provisions of CSA 2001 did not come into force until July 1, 2007 when certain regulations necessary to implement these provisions came into effect. CSA 2001 applies to all vessels operating in Canadian waters and in the Exclusive Economic Zone of Canada and establishes the primary regulatory and liability regime for oil pollution prevention and response.

CSA 2001 requires ship owners to have in place an arrangement with an approved pollution response organization. Vessels must carry a declaration, which identifies the vessel’s insurer and confirms that an arrangement with a response organization is in place. Failure of a vessel to comply with these requirements can result in a fine of up to C$1.0 million or imprisonment for a term of not more than 18 months, or both. Lesser offenses, such as failing to comply with the directions of a pollution prevention officer, are subject to a fine of not more than C$100,000.

CSA 2001 also makes it a strict liability offense to discharge a pollutant, including but not limited to, oil from a vessel. Vessels must have a shipboard oil pollution plan and implement the same in respect of an oil pollution incident. The maximum fine for marine pollution, or for failing to implement an oil pollution plan, is C$1 million or imprisonment for not more than 18 months, or both. If the discharge of a pollutant continues for more than one day, the person committing the offense may be convicted of a separate offense for each day on which the pollutant is discharged. Lesser offenses, such as failing to comply with directions of the Minister in respect of a pollution incident, are subject to a fine of not more than C$100,000. Depending upon the circumstances of the offense, a person convicted of an offense may be subject to other penalties, such being liable to fund the cost of conducting research into the ecological use and disposal of the pollutant in respect of which the offense was committed.

CSA 2001 also provides the authorities with broad discretionary powers to enforce its requirements. CSA 2001 authorizes the detention of a vessel where there are reasonable grounds for believing that the vessel caused marine pollution or that an offense has been committed.

S-6

USE OF PROCEEDS

We estimate that we will receive net proceeds of approximately $ million after deducting underwriting discounts and estimated offering expenses from the issuance of common shares in this offering, assuming that the underwriters’ over-allotment option is not exercised. We intend to use the net proceeds from this offering for general corporate purposes, including repayment of indebtedness, capital expenditures, working capital and to make vessel acquisitions. We intend to temporarily invest the proceeds of this offering in short-term, investment grade, liquid investments until the funds are required for the purposes described above.

UNDERWRITING

Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as joint bookrunning managers of the offering, and are acting as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus, each underwriter named below has agreed to purchase, and we have agreed to sell to that underwriter, the number of common shares set forth opposite the underwriter’s name.


Underwriter		Number of Shares
Citigroup Global Markets Inc.
Merrill Lynch, Pierce, Fenner & Smith Incorporated
Dahlman Rose & Company, LLC

Total		4,500,000

The underwriting agreement provides that the obligations of the underwriters to purchase the common shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the common shares (other than those covered by the over-allotment option described below) if they purchase any of the common shares.

The underwriters propose to offer some of the common shares directly to the public at the public offering price set forth on the cover page of this prospectus and some of the common shares to dealers at the public offering price with a selling concession not to exceed $ per share. If all of the common shares are not sold at the initial offering price, the representatives may change the public offering price and the other selling terms.

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 675,000 additional shares of common shares at the public offering price less the underwriting discount. The underwriters may exercise the option solely for the purpose of covering over-allotments, if any, in connection with this offering. To the extent the option is exercised, each underwriter must purchase a number of additional shares approximately proportionate to that underwriter’s initial purchase commitment.

We, and our officers and directors, and owners of our subordinated shares have agreed that, for a period of 60 days from the date of this prospectus supplement, we and they will not, without the prior written consent of Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, dispose of or hedge any shares of our common shares or any securities convertible into or exchangeable for our common shares. Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated in their sole discretion may release any of the securities subject to these lock-up agreements at any time without notice.

The common shares are listed on The New York Stock Exchange under the symbol “SSW.”

The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares of common shares.

In connection with the offering, Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated may purchase and sell common shares in the open market. These transactions may include short sales, syndicate covering transactions and stabilizing transactions. Short sales involve syndicate sales of

S-11

common shares in excess of the number of common shares to be purchased by the underwriters in the offering, which creates a syndicate short position. “Covered” short sales are sales of common shares made in an amount up to the number of common shares represented by the underwriters’ over-allotment option. In determining the source of common shares to close out the covered syndicate short position, the underwriters will consider, among other things, the price of common shares available for purchase in the open market as compared to the price at which they may purchase common shares through the over-allotment option. Transactions to close out the covered syndicate short involve either purchases of the common shares in the open market after the distribution has been completed or the exercise of the over-allotment option. The underwriters may also make “naked” short sales of shares in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of common shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of bids for or purchases of common shares in the open market while the offering is in progress.

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when an underwriter repurchases common shares originally sold by that syndicate member in order to cover syndicate short positions or make stabilizing purchases.

Any of these activities may have the effect of preventing or retarding a decline in the market price of the common shares. They may also cause the price of the common shares to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions on The New York Stock Exchange or in the over-the-counter market, or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

We estimate that our total expenses of this offering excluding underwriting discounts and commissions will be approximately $ .

All of the underwriters in this offering were also underwriters of our initial public offering completed on August 12, 2005. The underwriters and their affiliates may, from time to time in the future, engage in additional transactions with us and perform services for us in the ordinary course of business.

A prospectus in electronic format may be made available on the websites maintained by one or more of the underwriters. The representatives may agree to allocate a number of shares to underwriters for sale to their online brokerage account holders. The representatives will allocate shares to underwriters that may make Internet distributions on the same basis as other allocations. In addition, shares may be sold by the underwriters to securities dealers who resell shares to online brokerage account holders.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or the Securities Act or to contribute to payments the underwriters may be required to make because of any of those liabilities.

Information provided by the Company

We will furnish, on request, holders of our common shares with annual reports containing audited financial statements and a report by our independent registered public accounting firm. The audited financial statements will be prepared in accordance with United States generally accepted accounting principles and those reports will include a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section for the relevant periods. As a “foreign private issuer,” we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements to shareholders. While we intend to furnish proxy statements to any shareholder in accordance with the rules of The New York Stock Exchange, those proxy statements are not expected to conform to Schedule 14A of the proxy rules promulgated under the Exchange Act. 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.

S-17

ENFORCEABILITY OF CIVIL LIABILITIES

We are a Marshall Islands corporation, and our executive offices are located outside of the United States in Hong Kong. A majority of our directors and officers and some of the experts named in this prospectus reside outside of the United States. In addition, a substantial portion of our assets and the assets of our directors, officers and experts are located outside of the United States. As a result, you may have difficulty serving legal process within the United States upon us or any of these persons. You may also have difficulty enforcing, both in and outside the United States, judgments you may obtain in U.S. courts against us or those 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 the courts of the Marshall Islands or Hong Kong would (1) enter judgments in original actions brought in those courts predicated on U.S. federal or state securities laws, or (2) recognize or enforce against us or any of our officers, directors or experts judgments of courts of the United States predicated on U.S. federal or state securities laws.

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, we have been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Information Provided by the Company

We will furnish holders of our common shares with annual reports containing audited financial statements and a report by our independent registered public accounting firm. The audited financial statements will be prepared in accordance with United States generally accepted accounting principles and those reports will include a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section for the relevant periods. As a “foreign private issuer,” we are exempt from the rules under the Exchange Act

prescribing the furnishing and content of proxy statements to shareholders. While we intend to furnish proxy statements to any shareholder in accordance with the rules of The New York Stock Exchange, those proxy statements are not expected to conform to Schedule 14A of the proxy rules promulgated under the Exchange Act. 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.

RISK FACTORS

An investment in our common shares involves a high degree of risk. Before you invest in our common shares you should carefully consider those risk factors included in our most recent annual report on Form 20-F, as supplemented by our reports on Form 6-K, each of which is incorporated herein by reference, those risk factors included in this prospectus and those risk factors that may be included in the applicable prospectus supplement together with all of the other information included in this prospectus, any prospectus supplement and the documents we incorporate by reference in evaluating an investment in our common shares. If any of the risks discussed in the foregoing documents were to occur, our business, financial condition, operating results or cash flows could be materially adversely affected. This may reduce our ability to pay dividends to our shareholders and lower the trading price of our common shares. You may lose all or part of your investment.

The enactment of proposed legislation could affect whether dividends paid by us constitute qualified dividend income eligible for the preferential rate.

Legislation was recently introduced in the United States Congress that would deny the preferential rate of federal income tax currently imposed on qualified dividend income with respect to dividends received from a non-U.S. corporation, unless the non-U.S. corporation either is eligible for benefits of a comprehensive income tax treaty with the United States or is created or organized under the laws of a foreign country which has a comprehensive income tax system. Because the Marshall Islands has not entered into a comprehensive income tax treaty with the United States and imposes only limited taxes on corporations organized under its laws, it is unlikely that we could satisfy either of these requirements. Consequently, if this legislation were enacted the preferential rate of federal income tax discussed in “United States Tax Considerations—United States Federal Income Taxation of U.S. Holders—Distributions” may no longer be applicable to dividends received from us. As of the date hereof, it is not possible to predict with any certainty whether the proposed legislation will be enacted.

FORWARD-LOOKING STATEMENTS

In addition to historical information, this prospectus contains forward-looking statements that involve risks and uncertainties. Such forward-looking statements relate to future events and our operations, objectives, expectations, performance, financial condition and intentions. When used in this prospectus, the words “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates,” “projects,” “forecasts,” “will,” “may,” “potential,” “should” and variations of such words and similar expressions are intended to identify forward-looking statements. These risks and uncertainties include, but are not limited to:

•

future operating or financial results;

•

our expectations relating to dividend payments and forecasts of our ability to make such payments;

•

pending acquisitions, business strategy and expected capital spending;

•

operating expenses, availability of crew, number of off-hire days, drydocking requirements and insurance costs;

•

general market conditions and shipping market trends, including charter rates and factors affecting supply and demand;

•

our financial condition and liquidity, including our ability to obtain additional financing in the future to fund capital expenditures, acquisitions and other general corporate activities;

•

estimated future capital expenditures needed to preserve our capital base;

•

our expectations about the availability of ships to purchase, the time that it may take to construct new ships, or the useful lives of our ships;

•

our continued ability to enter into long-term, fixed-rate time charters with our customers;

•

our ability to leverage to our advantage our Manager’s relationships and reputation in the containership industry;

•

changes in governmental rules and regulations or actions taken by regulatory authorities;

•

potential liability from future litigation; and

•

other factors detailed from time to time in our periodic reports, including our prospectus filed with the Commission on November 3, 2006.

Forward-looking statements in this prospectus are necessary estimates reflecting the judgment of senior management and involve known and unknown risks and uncertainties. These forward-looking statements are based upon a number of assumptions and estimates that are inherently subject to significant uncertainties and contingencies, many of which are beyond our control. Actual results may differ materially from those expressed or implied by such forward-looking statements. Accordingly, these forward-looking statements should be considered in light of various important factors, including those set forth in this prospectus and our most recent annual report on Form 20-F under the heading “Risk Factors.”

We do not intend to revise any forward-looking statements in order to reflect any change in our expectations or events or circumstances that may subsequently arise. We make no prediction or statement about the performance of our common and subordinated shares. You should carefully review and consider the various disclosures included in this prospectus and in our other filings made with the Commission that attempt to advise interested parties of the risks and factors that may affect our business, prospects and results of operations.

USE OF PROCEEDS

Unless we specify otherwise in any prospectus supplement, we will use the net proceeds we receive from the sale of our common shares offered by this prospectus for general corporate purposes, including capital expenditures, repayment of indebtedness, working capital and to make vessel acquisitions.

The actual application of proceeds we receive from the sale of any particular offering of our common shares using this prospectus will be described in the applicable prospectus supplement relating to such offering.

DESCRIPTION OF CAPITAL STOCK

The following is a description of the material terms of our articles of incorporation and bylaws. We refer you to our articles of incorporation and bylaws, copies of which have been filed as exhibits to our registration statement filed in connection with our initial public offering and incorporated by reference herein.

Purpose

Our purpose, as stated in our articles of incorporation, is to engage in any lawful act or activity relating to the business of chartering or rechartering containerships to others, any other lawful act or activity customarily conducted in conjunction with the chartering or rechartering of containerships to others, and any other lawful act or activity approved by a vote of our board of directors, and so long as the management agreement between us and our Manager has not been terminated, by a majority of outstanding incentive shares, voting separately as a class. “Containerships” includes any ocean-going vessel that is intended to be used primarily to transport containers or is being used primarily to transport containers. Notwithstanding the above, we may engage in any lawful act or activity not otherwise permitted by our articles of incorporation if such is related to any business operation acquired as part of an acquisition of an entity or business, a majority of whose value, as determined by our board of directors, is attributable to acts and activities permitted by the first sentence of this paragraph, provided, such act or activities are not subsequently expanded in any material respect. Our articles of incorporation and bylaws do not impose any limitations on the ownership rights of our shareholders.

Authorized and Outstanding Shares

Under our articles of incorporation, our authorized shares consist of 200,000,000 common shares (referred to in our articles of incorporation as the Class A Common Shares), par value $0.01 per share, 25,000,000 subordinated shares (referred to in our articles of incorporation as the Class B Common Shares), par value $0.01 per share, 100 incentive shares (referred to in our articles of incorporation as the Class C Common Shares), par value $0.01 per share, and 65,000,000 shares of preferred shares (referred to in our articles of incorporation as the Preferred Shares), par value $0.01 per share. As of December 31, 2006, 40,377,250 common shares, 7,145,000 subordinated shares, 100 incentive shares and no preferred shares are issued and outstanding.

Common Shares

Under our articles of incorporation, our common shares will receive quarterly dividends from our operating surplus (as defined below) of $0.425 per share, plus any arrearages in the payment of the $0.425 per share amount from prior quarters, before our subordinated shares are entitled to any dividends from operating surplus. Our common shares will accrue arrearages during the subordination period. The common shares have the voting rights described below under “Voting.”

Subordinated Shares

All of our subordinated shares are owned by trusts set up on behalf of certain members of the Washington family, by our chief executive officer, Gerry Wang, and by an entity owned by Graham Porter, a director of our Manager. Under our articles of incorporation, our subordinated shares may not receive any dividends from our operating surplus (as defined below), until after our common shares have received a quarterly dividend of $0.425 per share and any arrearages in the payment of the $0.425 per share amount from prior quarters. Our subordinated shares do not accrue arrearages. Our subordinated shares will convert to common shares on a one-for-one basis after the expiration of the subordination period as discussed below under “Dividends—Subordination Period.” The subordinated shares have the voting rights described below under “Voting.”

Incentive Shares

Our Manager owns incentive shares that are entitled to share in incremental dividends if target dividend levels have been met. Incentive shares will not convert to common shares. The incentive shares have the voting rights described below under “Voting.”

Dividends

Declaration and payment of any dividend is subject to the discretion of our board of directors. The time and amount of dividends will be dependant upon our financial condition, our operations, our cash requirements and availability, debt repayment obligations, capital expenditure needs, restrictions in our debt instruments, industry trends, the provisions of Marshall Islands law affecting the payment of distributions to shareholders and other factors. The Marshall Islands Business Corporations Act, or BCA, generally prohibits the payment of dividends other than from paid-in capital in excess of par value and our earnings or while we are insolvent or would be rendered insolvent on paying the dividend. In the discussion below, we refer to the quarterly dividend of $0.425 per share as our “base dividend.” If we pay an amount in excess of the base dividend in a quarterly period during the subordination period, it will be paid equally to each common and subordinated share.

All dividends paid to shareholders will be treated as either a dividend from operating surplus or a liquidating dividend. Our board of directors will treat all dividends as coming from operating surplus until the sum of all dividends paid since the closing of our initial public offering equals the amount of operating surplus as of the most recent date of determination. Our undistributed operating surplus at any point in time will be our operating surplus accumulated since the closing of our initial public offering less all dividends from operating surplus paid since the closing of our initial public offering. We will treat dividends paid from any amount in excess of our operating surplus as liquidating dividends.

We will pay dividends on our common and subordinated shares from operating surplus, if any, for any quarter, in the following manner:

•

first, 100% to all common shares, pro rata, until they receive $0.425 per share;

•

second, 100% to all common shares, pro rata, until they have received any unpaid arrearages in the $0.425 per share dividend for prior quarters;

•

third, 100% to all subordinated shares, pro rata, until they have received $0.425 per share;

•

after that, 100% to all common and subordinated shares, pro rata, as if they were a single class, subject to the right of the incentive shares to share in incremental dividends, based on specified sharing ratios, once dividends on the common and subordinated shares reach specified target levels beginning with $0.485 per share.

Subordinated shares are not entitled to any arrearages. Liquidating dividends will be paid equally to each common and subordinated share and will not be paid to incentive shares. We do not expect to pay liquidating dividends.

Operating Surplus. Operating surplus generally means:

•

$15.0 million (which may be increased to $30.0 million as described below); plus

•

all of our cash receipts after the completion of our initial public offering, excluding cash receipts from (1) borrowings, (2) sales of equity and debt securities, (3) capital contributions, (4) corporate reorganizations or restructurings, (5) the termination of interest rate swap agreements, (6) sales or other dispositions of vessels and (7) sales or other dispositions of other assets other than in the normal course of business; plus

•

interest paid on debt incurred and cash dividends paid on equity securities issued by us, in each case, to finance all or any portion of the construction, replacement or improvement of a capital asset such as vessels (other than our Contracted Fleet (as such term is defined in our amended and restated articles of incorporation)) during the period from such financing until the earlier to occur of the date the capital asset is put into service or the date that it is abandoned or disposed of; plus

•

interest paid on debt incurred and cash dividends paid on our equity securities issued by us, in each case, to pay the construction period interest on debt incurred, or to pay construction period dividends

on our equity issued to finance the construction projects described in the immediately preceding bullet; less

•

all of our cash expenditures after the completion of our initial public offering, including, but not limited to operating expenses, interest payments and taxes, but not (1) the repayment of borrowings, (2) the repurchase of debt and equity securities, (3) interest rate swap termination costs, (4) expenses and taxes related to borrowings, sales of equity and debt securities, capital contributions, corporate reorganizations or restructurings, the termination of interest rate swap agreements, sales or other dispositions of vessels, and sales or dispositions of other assets other than in the normal course of business, (5) capital expenditures and (6) payment of dividends; less

•

cash capital expenditures incurred after the completion of our initial public offering to maintain our vessels and other assets including drydocking, replacement of equipment on the vessels, repairs and similar expenditures, but excluding capital expenditures for or related to the acquisition of additional vessels, and including capital expenditures for replacement of a vessel as a result of damage or loss prior to normal retirement, net of any insurance proceeds, warranty payments or similar property not treated as cash receipts for this purpose; less

•

the amount of cash reserves established by our board of directors for future (1) operating expenditures and (2) maintenance capital expenditures.

The $15.0 million amount in the first bullet point above may be increased by our board of directors to $30.0 million only if our board determines such increase is necessary to allow it to pay all or part of the base dividend on our common shares. The $15.0 million amount cannot be increased in any period in which a dividend on subordinated shares is paid or is payable. Expenditures in the fifth bullet above are referred to as operating expenditures and those in the sixth bullet are referred to as maintenance capital expenditures. When the term “interest” is used in the bullets above, it includes periodic payments made by us under interest rate swap agreements.

As described above, our operating surplus for determining whether we are paying ordinary dividends or liquidating dividends does not reflect only cash on hand that is generated from our operations. For example, it includes a provision that will enable us to pay, under circumstances described above, a dividend from our operating surplus of up to $30.0 million of cash we receive from non-operating sources, such as asset sales, issuances of securities and borrowings. In addition, the effect of including, as described above, certain dividends on equity securities or interest payments on debt related to the construction, replacement or improvement of an asset in operating surplus would be to increase our operating surplus by the amount of any such dividends or interest payments. As a result, we may also pay dividends from our operating surplus up to the amount of any such dividends or interest payments from cash we receive from non-operating sources.

In return for the fee we pay our Manager for the technical management of our vessels, our Manager is responsible for all maintenance capital expenditures for our vessels other than extraordinary items described in our management agreement. That fee is treated as an operating expenditure and deducted in determining our operating surplus. As a result, we will not separately deduct a maintenance capital item so long as we continue our existing arrangement with our Manager or a similar arrangement regarding technical services for our vessels.

Our articles of incorporation provide that the construction or application of the definition of operating surplus may be adjusted in the case of any particular transaction or matter or type of transaction or matter if our board of directors, with the concurrence of our audit committee, is of the opinion that the adjustment is necessary or appropriate to further the overall purpose and intent of the definition of operating surplus.

Liquidating Dividends. In general, liquidating dividends will only be generated from:

•

borrowings;

•

sales of debt and equity securities;

•

sales or other dispositions of vessels; and

•

sales or other dispositions of other assets, other than assets sold in the ordinary course of business.

We do not expect to pay liquidating dividends.

Common Share Arrearages. In general, to the extent that during the subordination period our common shares do not receive dividends from operating surplus each quarter in an amount at least equal to the base dividend, a common share arrearage will accrue in the amount of the shortfall. If we sell common shares when any common share arrearage exists, the aggregate amount of the common share arrearage shall be deemed increased so that the amount of the arrearage per common share after the sale shall be the same as the arrearage per common share before the sale.

Adjustment of Base Dividend and Target Dividend Amounts. The base dividend and target dividend amounts for the incentive shares are subject to downward adjustment in the case of liquidating dividends. The base dividend and the target dividend amounts will be reduced in the same proportion that the liquidating dividend had to the fair market value of the common shares prior to the payment of the dividend. If the common shares are publicly traded on a national securities exchange or market, that price will be the average closing sale price on each of the five trading days before the ex-dividend date. If the shares are not publicly traded, the price will be determined by our board of directors.

In addition to the adjustment for liquidating dividends, if we combine our shares into fewer shares or subdivide our shares into a greater number of shares, we will proportionately adjust the base dividend and the target dividend levels.

Subordination Period. The subordination period will extend until the first day after the quarter ending September 30, 2008, that each of the following tests have been met:

•

we have paid a dividend in the amount at least equal to the base dividend per share on both the common and subordinated shares for the immediately preceding four-quarter period; and

•

our operating surplus (excluding the amount under the first bullet in the definition of operating surplus) generated during the four-quarter period referred to above at least equaled the base dividend on all of the outstanding common and subordinated shares on a fully diluted basis during that period.

For purposes of the tests, our articles of incorporation provide that our operating surplus generated during the four-quarter period not only exclude all operating surplus existing at the beginning of the period but also, for the sake of clarity, expressly exclude the reversal, during the four-quarter period, of any unused reserves in existence as of the beginning of the period. It is not deemed a reversal if the reserve is drawn down to be used as an expenditure during the period for the purpose the reserve was originally established.

Notwithstanding the tests above, the subordination period will end immediately preceding the occurrence of a change of control of us. As a result, each subordinated share will convert into a common share. Change of control as used here has the same meaning as in the management agreement.

Voting

The common shares and the subordinated shares each have one vote and vote together as a single class except that (i) any amendment to the articles of incorporation, including those made pursuant to the terms of any merger, consolidation or similar transaction, that would increase or decrease the aggregate number of authorized common shares, increase or decrease the par value of the common shares, or alter or change the powers, preferences or rights of the common shares so as to affect them adversely, must be approved by the holders of not less than a majority of the common shares and (ii) any amendment to the articles of incorporation made pursuant to the terms of any merger, consolidation or similar transaction, that would increase or decrease the aggregate number of authorized subordinated shares, increase or decrease the par value of the subordinated

shares, or alter or change the powers, preferences or rights of the subordinated shares so as to affect them adversely, must be approved by the holders of not less than a majority of the subordinated shares. Our directors are elected by a plurality vote of the common and subordinated shares voting as a single class. A majority of the common shares and subordinated shares in the aggregate shall constitute a quorum. The incentive shares have no voting rights except (i) that any amendment to the articles of incorporation, including those made pursuant to the terms of any merger, consolidation or similar transaction, that would increase or decrease the aggregate number of authorized incentive shares, increase or decrease the par value of the incentive shares, or alter or change the powers, preferences or rights of the incentive shares so as to affect them adversely, must be approved by the holders of not less than a majority of the incentive shares and (ii) for so long as our management agreement has not been terminated, any proposed amendment to our purpose as set forth in our articles of incorporation must be approved by not less than a majority of the votes entitled to be cast by the holders of the incentive shares. Any preferred shares have whatever voting rights are provided on their issuance.

Preferred Shares

Our articles of incorporation authorize our board of directors to establish one or more series of preferred shares and to determine, with respect to any series of preferred shares, the terms and rights of that series, including:

•

the designation of the series;

•

the number of shares in the series, which our board of directors may, except where otherwise provided in the preferred shares designation, increase or decrease, but not below the number of shares then outstanding;

•

whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

•

the dates at which dividends, if any, will be payable;

•

the redemption rights and price or prices, if any, for shares of the series;

•

the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series;

•

the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of our company;

•

whether the shares of the series will be convertible into shares of any other class or series, or any other security, of our company or any other corporation, and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

•

restrictions on the issuance of shares of the same series or of any other class or series; and

•

the voting rights, if any, of the holders of the series.

For purposes of calculating operating surplus, dividends on preferred shares will be treated as if they were interest payments and not dividends.

Anti-Takeover Effects of Certain Provisions of Our Articles of Incorporation and Bylaws

Certain provisions of our articles of incorporation and bylaws, which are summarized in the following paragraphs, may have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a shareholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by shareholders.

Classified Board of Directors

Our articles of incorporation provide for a board of directors serving staggered, three-year terms. Approximately one-third of our board of directors is elected each year. This classified board provision could discourage a third party from making a tender offer for our shares or attempting to obtain control of us. It could also delay shareholders who do not agree with the policies of the board of directors from removing a majority of the board of directors for two years.

Removal of Directors; Vacancies

Our articles of incorporation and bylaws provide that directors may be removed with cause upon the affirmative vote of holders of a majority of the shares entitled to vote generally in the election of directors, voting together as a single class. In addition, our articles of incorporation and bylaws also provide that any vacancies on our board of directors and newly created directorships will be filled only by the affirmative vote of a majority of the remaining directors, although less than a quorum.

No Cumulative Voting

The BCA provides that shareholders are not entitled to the right to cumulate votes in the election of directors unless our articles of incorporation provide otherwise. Our articles of incorporation prohibit cumulative voting.

Calling of Special Meetings of Shareholders

Our bylaws provide that special meetings of our shareholders may be called only by the chairman of our board of directors or by resolution of our board of directors.

Advance Notice Requirements for Shareholder Proposals and Director Nominations

Our bylaws provide that shareholders seeking to nominate candidates for election as directors or to bring business before an annual meeting of shareholders must provide timely notice of their proposal in writing to the corporate secretary.

Generally, to be timely, a shareholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the date on which we first mailed our proxy materials for the previous year’s annual meeting. Our bylaws also specify requirements as to the form and content of a shareholder’s notice. These provisions may impede shareholders’ ability to bring matters before an annual meeting of shareholders or make nominations for directors at an annual meeting of shareholders.

Amendments to Our Bylaws

Our articles of incorporation and bylaws grant our board of directors the authority to amend and repeal our bylaws without a shareholder vote in any manner not inconsistent with the laws of the Republic of the Marshall Islands and our articles of incorporation. Shareholders may amend our bylaws by a vote of not less than 80% of the shares entitled to vote.

Business Combinations

Although the BCA does not contain specific provisions regarding “business combinations” between companies organized under the laws of the Marshall Islands and “interested shareholders,” we have included these provisions in our articles of incorporation. Specifically, our articles of incorporation contain provisions that prohibit us from engaging in a business combination with an interested shareholder for a period of three years following the date of the transaction in which the person became an interested shareholder, unless, in addition to any other approval that may be required by applicable law:

•

prior to the date of the transaction that resulted in the shareholder becoming an interested shareholder, our board of directors approved either the business combination or the transaction that resulted in the shareholder becoming an interested shareholder;

•

upon consummation of the transaction that resulted in the shareholder becoming an interested shareholder, the interested shareholder owned at least 85% of our voting shares outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned (i) by persons who are directors and officers, and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer;

•

after the date of the transaction that resulted in the shareholder becoming an interested shareholder, the business combination is approved by our board of directors and authorized at an annual or special meeting of shareholders, and not by written consent, by the affirmative vote of at least 66 ²/3% of our outstanding voting shares that are not owned by the interested shareholder;

•

the shareholder became an interested shareholder prior to the completion of our initial public offering; or

•

the interested shareholder is Gerry Wang, Graham Porter, Dennis Washington, Kyle Washington or any of their affiliates, or any person that purchases shares from any of those individuals or any of their affiliates, provided, the person that purchased such shares does not own more than 1% of our outstanding shares at the time of such acquisition or acquire more than an additional 1% of our outstanding shares other than from those individuals or any of their affiliates.

Generally, a “business combination” includes any merger or consolidation of us or any direct or indirect majority-owned subsidiary of ours with (i) the interested shareholder or any of its affiliates, or (ii) with any corporation, partnership, unincorporated association or other entity if the merger or consolidation is caused by the interested shareholder. Generally, an “interested shareholder” is any person or entity that (i) owns 15% or more of our outstanding voting shares, (ii) is an affiliate or associate of us and was the owner of 15% or more of our outstanding voting shares at any time within the three-year period immediately prior to the date on which it is sought to be determined whether such person is an interested shareholder, or (iii) the affiliates and associates of any person listed in (i) or (ii), except that any person who owns 15% or more of our outstanding voting shares, as a result of action taken solely by us shall not be an interested shareholder unless such person acquires additional voting shares, except as a result of further action by us, not caused, directly or indirectly, by such person.

Dissenters’ Rights of Appraisal and Payment

Under the BCA, our shareholders have the right to dissent from various corporate actions, including any merger or consolidation or sale of all or substantially all of our assets not made in the usual course of our business, and receive payment of the fair value of their shares. In the event of any further amendment of our articles of incorporation, a shareholder also has the right to dissent and receive payment for his or her shares if the amendment alters certain rights in respect of those shares. The dissenting shareholder must follow the procedures set forth in the BCA to receive payment. In the event that we and any dissenting shareholder fail to agree on a price for the shares, the BCA procedures involve, among other things, the institution of proceedings in the high court of the Republic of the Marshall Islands or in any appropriate court in any jurisdiction in which our common shares are primarily traded on a local or national securities exchange.

Shareholders’ Derivative Actions

Under the BCA, any of our shareholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the shareholder bringing the action is a holder of common shares both at the time the derivative action is commenced and at the time of the transaction to which the action relates.

Limitations on Liability and Indemnification of Officers and Directors

The BCA authorizes corporations to limit or eliminate the personal liability of directors and officers to corporations and their shareholders for monetary damages for breaches of directors’ fiduciary duties. Our articles of incorporation include a provision that eliminates the personal liability of directors or officers for monetary damages for actions taken as a director or officer to the fullest extent permitted by law.

Our articles of incorporation provide that we must indemnify our directors and officers to the fullest extent authorized by law. We are also expressly authorized to advance certain expenses (including attorneys’ fees and disbursements and court costs) to our directors and officers and carry directors’ and officers’ insurance providing indemnification for our directors, officers and certain employees for some liabilities. We believe that these indemnification provisions and insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability and indemnification provisions in our articles of incorporation may discourage shareholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our shareholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

There is currently no pending material litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought.

Shareholder Rights Plan

General

Each of our common shares includes one right, or a right, that entitles the holder to purchase from us a unit consisting of one-thousandth of a preferred share at a purchase price of $25.00 per unit, subject to specified adjustments. The rights are issued pursuant to a rights agreement between us and American Stock Transfer & Trust Company, as rights agent. Until a right is exercised, the holder of a right will have no rights to vote or receive dividends or any other shareholder rights.

The rights may have anti-takeover effects. The rights will cause substantial dilution to any person or group that attempts to acquire us without the approval of our board of directors. As a result, the overall effect of the rights may be to render more difficult or discourage any attempt to acquire us. Because our board of directors can approve a redemption of the rights or a permitted offer, the rights should not interfere with a merger or other business combination approved by our board of directors. The adoption of the rights agreement was approved by our existing shareholders prior to our initial public offering.

We have summarized the material terms and conditions of the rights agreement and the rights below. For a complete description of the rights, we encourage you to read the rights agreement, which we have filed as an exhibit to the registration statement filed in connection with our initial public offering and incorporated by reference herein.

Detachment of the Rights

The rights are attached to all certificates representing our currently outstanding common shares and will attach to all common share certificates we issue prior to the rights distribution date that we describe below. The rights are not exercisable until after the rights distribution date and will expire at the close of business on the tenth anniversary date of the adoption of the rights plan, unless we redeem or exchange them earlier as we

describe below. The rights will separate from the common shares and a rights distribution date would occur, subject to specified exceptions, on the earlier of the following two dates:

•

10 days following a public announcement that a person or group of affiliated or associated persons or an “acquiring person,” has acquired or obtained the right to acquire beneficial ownership of 20% or more of our outstanding common shares; or

•

10 business days following the start of a tender or exchange offer that would result, if closed, in a person becoming an acquiring person.

Existing shareholders are excluded from the definition of “acquiring person” for purposes of the rights, and therefore their ownership cannot trigger the rights. In addition, any person that acquires from an existing shareholder common shares that would otherwise result in that person becoming an “acquiring person” will not become an acquiring person due to that acquisition. Specified “inadvertent” owners that would otherwise become an acquiring person, including those who would have this designation as a result of repurchases of common shares by us, will not become acquiring persons as a result of those transactions.

Our board of directors may defer the rights distribution date in some circumstances, and some inadvertent acquisitions will not result in a person becoming an acquiring person if the person promptly divests itself of a sufficient number of common shares.

Until the rights distribution date:

•

our common share certificates will evidence the rights, and the rights will be transferable only with those certificates;

•

any new common shares will be issued with rights and new certificates will contain a notation incorporating the rights agreement by reference.

As soon as practicable after the rights distribution date, the rights agent will mail certificates representing the rights to holders of record of our common shares at the close of business on that date. After the rights distribution date, only separate rights certificates will represent the rights.

We will not issue rights with any common shares we issue after the rights distribution date, except as our board of directors may otherwise determine.

Flip-In Event

A “flip-in event” will occur under the rights agreement when a person becomes an acquiring person otherwise than pursuant to a permitted offer. The rights agreement generally defines “permitted offer” to mean a tender or exchange offer for all outstanding common shares at a price and on terms that a majority of the members of our board of directors who are independent from the acquiring person or the person making the offer determines to be fair to and otherwise in the best interests of our company and our shareholders.

If a flip-in event occurs and we do not redeem the rights as described under the heading “Redemption of Rights” below, each right, other than any right that has become void, as we describe below, will become exercisable at the time it is no longer redeemable for the number of common shares, or, in some cases, cash, property or other of our securities, having a current market price equal to two times the exercise price of such right.

When a flip-in event occurs, all rights that then are, or in some circumstances that were, beneficially owned by or transferred to an acquiring person or specified related parties will become void in the circumstances the rights agreement specifies.

Flip-Over Event

A “flip-over event” will occur under the rights agreement when, at any time after a person has become an acquiring person:

•

we are acquired in a merger or other business combination transaction, other than specified mergers that follow a permitted offer of the type we describe above; or

•

50% or more of our assets, cash flow or earning power is sold or transferred.

If a flip-over event occurs, each holder of a right, other than any right that has become void as we describe under the heading “Flip-In Event” above, will have the right to receive the number of common shares of the acquiring company, which has a current market price equal to two times the exercise price of such right.

Antidilution

The number of outstanding rights associated with our common shares is subject to adjustment for any split, dividend or subdivision, combination or reclassification of our common shares occurring prior to the rights distribution date. With some exceptions, the rights agreement will not require us to adjust the exercise price of the rights until cumulative adjustments amount to at least 1% of the exercise price. It also will not require us to issue fractional shares of our preferred shares that are not integral multiples of one one-hundredth of a share, and, instead we may make a cash adjustment based on the market price of our common shares on the last trading date prior to the date of exercise. The rights agreement reserves to us the right to require prior to the occurrence of any flip-in event or flip-over event that, on any exercise of rights, a number of rights must be exercised so that we will issue only whole shares.

Redemption of Rights

At any time until 10 days after the date on which the occurrence of a flip-in event is first publicly announced, we may redeem the rights in whole, but not in part, at a redemption price of $.01 per right. The redemption price is subject to adjustment for any split, dividend or similar transaction occurring before the date of redemption. At our option, we may pay that redemption price in cash, common shares or any other consideration our board of directors may select. The rights are not exercisable after a flip-in event until they are no longer redeemable. If our board of directors timely orders the redemption of the rights, the rights will terminate on the effectiveness of that action.

Exchange of Rights

We may, at our option, exchange the rights (other than rights owned by an acquiring person or an affiliate or an associate of an acquiring person, which have become void), in whole or in part. The exchange will be at an exchange ratio of one common share per right, subject to specified adjustments at any time after the occurrence of a flip-in event and prior to:

•

any person other than our existing shareholders becoming the beneficial owner of common shares with voting power equal to 50% or more of the total voting power of all common shares entitled to vote in the election of directors; or

•

the occurrence of a flip-over event.

Amendment of Terms of Rights

During the time the rights are redeemable, we may amend any of the provisions of the rights agreement, other than by decreasing the redemption price. Once the rights cease to be redeemable, we generally may amend the provisions of the rights agreement, other than to decrease the redemption price, only as follows:

•

to cure any ambiguity, defect or inconsistency;

•

to make changes that do not materially adversely affect the interests of holders of rights, excluding the interests of any acquiring person; or

•

to shorten or lengthen any time period under the rights agreement, except that we cannot lengthen the time period governing redemption or lengthen any time period that protects, enhances or clarifies the benefits of holders of rights other than an acquiring person.

Transfer Agent and Registrar

The transfer agent and registrar for the common shares is American Stock Transfer and Trust Company.

Listing

Our common shares are listed on The New York Stock Exchange under the symbol “SSW.”

Compliance with Section 404 of the Sarbanes-Oxley Act of 2002

Based on our aggregate world market capitalization, we are not required to provide an auditor’s attestation report on internal control over financial reporting in our annual reports until fiscal years ending on or after July 15, 2007. Thus, our annual report for the year ending December 31, 2007 will be our first annual report to include the auditor’s attestation report on internal control over financial reporting.

UNITED STATES TAX CONSIDERATIONS

The following is a discussion of the material U.S. federal income tax considerations that may be relevant to prospective shareholders. Unless otherwise noted, the following discussion is the opinion of Vinson & Elkins L.L.P., our U.S. counsel, insofar as it relates to matters of U.S. federal income tax law and legal conclusions with respect to those matters. The opinion of our counsel is dependent on the accuracy of representations made by us to them, including descriptions of our operations contained herein.

This discussion is based upon provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) as in effect on the date of this prospectus, existing final and temporary regulations thereunder (“Treasury Regulations”), and current administrative rulings, pronouncements and court decisions, all of which are subject to change, possibly with retroactive effect. Changes in these authorities may cause the tax consequences to vary substantially from the consequences described below. Unless the context otherwise requires, references in this section to “we,” “our” or “us” are references to Seaspan Corporation.

In addition, the following discussion is for general information purposes only and does not purport to be a comprehensive description of all of the U.S. federal income tax considerations applicable to us or the holders of our shares. Nor does this discussion comment on all aspects of U.S. federal income taxation which may be important to certain holders of our shares in light of their particular circumstances, such as holders subject to special tax rules (e.g., financial institutions, regulated investment companies, real estate investment trusts, insurance companies, traders in securities that have elected the mark-to-market method of accounting for their securities, persons liable for alternative minimum tax, broker-dealers, tax-exempt organizations, partnerships or other pass-through entities and their investors, or former citizens or long-term residents of the United States), persons that will hold our shares as part of a straddle, hedge, conversion, constructive sale, or other integrated transaction for U.S. federal income tax purposes, or persons that have a functional currency other than the U.S. dollar, all of whom may be subject to tax rules that differ significantly from those summarized below. If a partnership or other entity taxed as a pass-through entity holds our shares, the tax treatment of a partner will generally depend upon the status of the partner and upon the activities of the pass-through entity. If you are a partner in a pass-through entity that holds or may acquire our shares, you should consult your tax advisor to determine the appropriate tax treatment to you of that entity’s ownership of our shares.

No ruling has been or will be requested from the Internal Revenue Service (“IRS”) regarding any matter affecting us or prospective shareholders. Instead, we will rely on opinions of Vinson & Elkins L.L.P. Unlike a ruling, an opinion of counsel represents only that counsel’s best legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made here may not be sustained by a court if contested by the IRS. Any contest of this sort with the IRS may materially and adversely impact the market for our common shares and the prices at which our common shares trade. In addition, the costs of any contest with the IRS, principally legal, accounting and related fees, will result in a reduction in cash available for dividends and thus will be borne indirectly by our shareholders. Furthermore, our tax treatment, or the tax treatment of an investment in us, may be significantly modified by future legislative or administrative changes or court decisions. Any modifications may or may not be retroactively applied.

United States Federal Income Taxation of Our Company

Taxation of Operating Income

Unless exempt from U.S. federal income taxation under the rules discussed below, a foreign corporation that earns income from transportation beginning or ending in the United States is subject to U.S. federal income taxation under one of two alternative tax regimes: (i) the 4% gross basis tax or (ii) the net basis tax and branch profits tax.

The 4% Gross Basis Tax

We may be subject to a 4% U.S. federal income tax on the U.S. source portion of our gross income (without benefit of deductions) attributable to transportation that begins or ends (but not both) in the United

States, unless the exemption provided under Section 883 of the Code (the “Section 883 Exemption”) applies (as more fully described below under “The Section 883 Exemption”) and we file a U.S. federal income tax return to claim that exemption. For this purpose, gross income attributable to transportation (“Transportation Income”) includes income from the use, hiring or leasing of a vessel to transport cargo, or the performance of services directly related to the use of any vessel to transport cargo, and thus includes time charter or bareboat charter income. The U.S. source portion of our Transportation Income is deemed to be 50% of the income attributable to voyages that begin or end (but not both) in the United States. Generally, no amount of the income from voyages that begin and end outside the United States is treated as U.S. source, and consequently none of the Transportation Income attributable to such voyages is subject to U.S. federal income tax. Although the entire amount of Transportation Income from voyages that begin and end in the United States would be U.S. source, we do not expect to have any Transportation Income from voyages that begin and end in the United States.

The Net Basis Tax and Branch Profits Tax

We currently do not have (and do not expect to have) a fixed place of business in the United States. Nonetheless, if this were to change or we otherwise were treated as having such a fixed place of business involved in earning U.S. source Transportation Income, such Transportation Income may be treated as effectively connected with the conduct of a trade or business in the United States (“U.S. Effectively Connected Income”).

If, contrary to the above, we earn U.S. Effectively Connected Income, that income would be subject to U.S. federal corporate income tax (the highest statutory rate is currently 35%) unless the Section 883 Exemption (as discussed below) applies. However, the 4% U.S. federal income tax described above is inapplicable to U.S. Effectively Connected Income.

Unless the Section 883 Exemption applies, a 30% branch profits tax imposed under Section 884 of the Code also would apply to any earnings resulting from our U.S. Effectively Connected Income, and a branch interest tax could be imposed on certain interest paid or deemed paid by us. Furthermore, on the sale of a ship that has produced U.S. Effectively Connected Income, we could be subject to the net basis corporate income tax and to the 30% branch profits tax with respect to our gain not in excess of certain prior deductions for depreciation that reduced U.S. Effectively Connected Income. Otherwise, we would not be subject to U.S. federal income tax with respect to gain realized on the sale of a ship, provided the sale is considered to occur outside of the United States under U.S. federal income tax principles.

The Section 883 Exemption

In general, the Section 883 Exemption provides that if a non-U.S. corporation satisfies the requirements of Section 883 of the Code and the Treasury Regulations thereunder (the “Section 883 Regulations”), it will not be subject to the 4% gross basis tax or the net basis tax and branch profits tax described above on its U.S. source Transportation Income attributable to voyages that begin or end (but not both) in the United States (“U.S Source International Shipping Income”).

A non-U.S. corporation will qualify for the Section 883 Exemption if, among other things, it meets the following three requirements:

(i)

it is organized in a jurisdiction outside the United States that grants an equivalent exemption from tax to corporations organized in the United States (an “Equivalent Exemption”);

(ii)

it satisfies one of the following three ownership tests: (a) the more than 50% ownership test (the “50% Ownership Test”), (b) the controlled foreign corporation test (the “CFC Test”) or (c) the “Publicly Traded Test”; and

(iii)

it meets certain substantiation, reporting, and other requirements.

We are organized under the laws of the Republic of the Marshall Islands. The U.S. Treasury Department has recognized the Republic of the Marshall Islands as a jurisdiction that grants an Equivalent Exemption; therefore, we meet the first requirement for the Section 883 Exemption.

Regarding the second requirement for the Section 883 Exemption, we do not expect to meet the 50% Ownership Test or the CFC Test. The analysis of our ability to meet the Publicly Traded Test follows.

The Publicly Traded Test

The Publicly Traded Test requires that one or more classes of equity representing more than 50% of the voting power and value in a non-U.S. corporation be “primarily and regularly traded” on an established securities market either in the United States or in a foreign country that grants an Equivalent Exemption. For this purpose, if one or more 5% shareholders own in the aggregate 50% or more of the vote and value of a class of equity for more than half of the days during a taxable year, such class of equity will not be treated as primarily and regularly traded on an established securities market for that year (the “5% Override Rule”). For purposes of applying the 5% Override Rule, a 5% shareholder is a shareholder holding, directly, indirectly or constructively, at least 5% of the vote and value of a class of equity (a “5% Shareholder”).

The Section 883 Regulations provide, in pertinent part, that stock of a foreign corporation will be considered to be “primarily traded” on an established securities market in a given country if the number of shares of each class of stock that are traded during any taxable year on all established securities markets in that country exceeds the number of shares in each such class that are traded during that year on established securities markets in any other single country. We anticipate that our common shares, including common shares issued in connection with this prospectus, will be “primarily traded” on The New York Stock Exchange during the current year and foreseeable future years.

Under the Section 883 Regulations, our shares will be considered to be “regularly traded” on an established securities market if one or more classes of our stock representing in the aggregate more than 50% of our outstanding stock, by voting power and value, is listed on such market or markets, which we refer to as the listing threshold. We believe our common shares listed on The New York Stock Exchange will represent more than 50% of our outstanding stock by voting power and expect that such shares also will represent more than 50% of our outstanding stock by value for the current year and foreseeable future years. Therefore, we believe that we will satisfy the listing threshold.

It is further required with respect to each class of stock relied upon to meet the listing threshold that: (i) such class of stock is traded on an established securities market, other than in minimal quantities, on at least 60 days during the taxable year or 1/6 of the days in a short taxable year; and (ii) the aggregate number of shares of such class of stock traded on such market during the taxable year is at least 10% of the average number of shares of such class of stock outstanding during such year or as appropriately adjusted in the case of a short taxable year. We expect that we will satisfy these trading frequency and trading volume tests for the current year and foreseeable future years.

As discussed above, if 50% or more of our common shares are owned by 5% Shareholders for more than half of the days during a taxable year, our common shares will be treated as failing the Publicly Traded Test under the 5% Override Rule. To identify 5% Shareholders for purposes of applying the 5% Override Rule, the Section 883 Regulations permit us to rely on those persons who are identified on Schedule 13G and Schedule 13D filings with the Commission as having a 5% or more beneficial interest in our common shares. The Section 883 Regulations further provide that an investment company that is registered under the Investment Company Act of 1940, as amended, will not be treated as a 5% Shareholder for such purposes.

There is some uncertainty as to whether our common and subordinated shares will be treated as a single or two separate classes of stock for purposes of applying the 5% Override Rule. At the present time, regardless of whether they are treated as a single or two separate classes of stock for this purpose, we expect that we will not be subject to the 5% Override Rule for the current year and therefore will satisfy the Publicly Traded Test and qualify for the Section 883 Exemption for the current year. However, 5% Shareholders may acquire or own additional stock in us at any time, and thus there can be no assurance that we will not be subject to the 5% Override Rule for the current or any future year, and there can be no assurance that we will qualify for the Section 883 Exemption for the current or any future year.

United States Federal Income Taxation of U.S. Holders

As used herein, the term “U.S. Holder” means a beneficial owner of our common shares that is an individual U.S. citizen or resident, U.S. corporation or other U.S. entity taxable as a corporation, an estate the income of which is subject to U.S. federal income taxation regardless of its source, or a trust if a court within the United States is able to exercise primary jurisdiction over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust.

Distributions

Subject to the discussion of passive foreign investment companies (“PFICs”), below, any distributions made by us with respect to our common shares to a U.S. Holder will generally constitute dividends, which may be taxable as ordinary income or “qualified dividend income” as described in more detail below, to the extent of our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our earnings and profits will be treated first as a nontaxable return of capital to the extent of the U.S. Holder’s tax basis in his common shares on a dollar-for-dollar basis and thereafter as capital gain. Because we are not a U.S. corporation, U.S. Holders that are corporations generally will not be entitled to claim a dividends received deduction with respect to any distributions they receive from us. Dividends paid with respect to our common shares will generally be treated as “passive category income” for purposes of computing allowable foreign tax credits for U.S. federal income tax purposes.

Dividends paid on our common shares to a U.S. Holder who is an individual, trust or estate (a “U.S. Individual Holder”) will be treated as “qualified dividend income” that is taxable to such U.S. Individual Holder at preferential tax rates (through 2010) provided that: (i) such shares are readily tradable on an established securities market in the United States (such as The New York Stock Exchange on which our common shares are traded); (ii) we are not a PFIC for the taxable year during which the dividend is paid or the immediately preceding taxable year (which we do not believe we are, have been or will be); (iii) the U.S. Individual Holder has owned the shares for more than 60 days in the 121-day period beginning 60 days before the date on which the common shares become ex-dividend; and (iv) the U.S. Individual Holder is not under an obligation to make related payments with respect to positions in substantially similar or related property. There is no assurance that any dividends paid on our common shares will be eligible for these preferential rates in the hands of a U.S. Individual Holder. In the absence of legislation extending the term of the preferential tax rates for qualified dividend income, all dividends received by a taxpayer in tax years beginning January 1, 2011 or later will be taxed at rates applicable to ordinary income.

Under proposed legislation, the preferential rate of federal income tax currently imposed on qualified dividend income would be denied with respect to dividends received from a non-U.S. corporation, unless the non-U.S. corporation either is eligible for benefits of a comprehensive income tax treaty with the United States or is created or organized under the laws of a foreign country which has a comprehensive income tax system. Because the Marshall Islands has not entered into a comprehensive income tax treaty with the United States and imposes only limited taxes on corporations organized under its laws, it is unlikely that we could satisfy either of these requirements. Consequently, if this legislation were enacted the preferential rate of federal income tax imposed on qualified dividend income may no longer be applicable to dividends received from us. As of the date hereof, it is not possible to predict with any certainty whether the proposed legislation will be enacted.

Special rules may apply to any “extraordinary dividend” paid by us. An extraordinary dividend is, generally, a dividend equal to or in excess of 10 percent of a shareholder’s adjusted basis (or fair market value in certain circumstances) in a common share. If we pay an “extraordinary dividend” on our common shares that is treated as “qualified dividend income,” then any loss derived by a U.S. Individual Holder from the sale or exchange of such common shares will be treated as long-term capital loss to the extent of such dividend.

Any dividends paid on our common shares that are not eligible for the preferential rate of tax on qualified dividend income will be taxed as ordinary income to a U.S. Individual Holder. See below for special rules, however, that may be applicable in the event we are treated as a PFIC.

Consequences of Possible CFC Classification

If more than 50% of either the total combined voting power of our outstanding shares entitled to vote or the total value of all of our outstanding shares were owned, directly, indirectly or constructively, by citizens or residents of the United States, U.S. partnerships or corporations, or U.S. estates or trusts (as defined for U.S. federal income tax purposes), each of which owned, directly, indirectly or constructively, 10% or more of the total combined voting power of our outstanding shares entitled to vote (each, a “CFC Shareholder”), we could be treated as a controlled foreign corporation (“CFC”). CFC Shareholders are treated as receiving current distributions of their shares of certain income of the CFC (not including, under current law, certain undistributed earnings attributable to shipping income) without regard to any actual distributions and are subject to other burdensome U.S. federal income tax and administrative requirements but generally are not also subject to the requirements generally applicable to shareholders of a PFIC. Although we do not believe we are a CFC, U.S. persons purchasing a substantial interest in us should consider the potential implications of being treated as a CFC Shareholder in the event we become a CFC in the future.

Sale, Exchange or other Disposition of Common Shares

Subject to the PFIC discussion, below, a U.S. Holder generally will recognize taxable gain or loss upon a sale, exchange or other disposition of our common shares in an amount equal to the difference between the amount realized by the U.S. Holder from such sale, exchange or other disposition and the U.S. Holder’s tax basis in such shares. Subject to the discussion of extraordinary dividends above, such gain or loss will be treated as long-term capital gain or loss if the U.S. Holder’s holding period is greater than one year at the time of the sale, exchange or other disposition. Such capital gain or loss will generally be treated as U.S.-source income or loss, as applicable, for U.S. foreign tax credit purposes. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations.

Consequences of Possible PFIC Classification

Special and adverse U.S. federal income tax rules apply to a U.S. Holder that owns an interest in a non-U.S. entity taxed as a corporation and classified as a PFIC for U.S. federal income tax purposes. In general, we will be treated as a PFIC with respect to a U.S. Holder if, for any taxable year in which such holder held our common shares, either (i) at least 75% of our gross income for such taxable year consists of passive income (e.g., dividends, interest, capital gains and rents derived other than in the active conduct of a rental business), or (ii) at least 50% of the average value of the assets held by us during such taxable year is attributable to assets that produce passive income or are held for the production of passive income.

For purposes of determining whether we are a PFIC, we are treated as earning and owning our proportionate share of the income and assets, respectively, of any of our subsidiaries in which we own at least 25% of the value of the subsidiary’s stock. Income earned, or deemed earned, by us in connection with the performance of services does not constitute passive income. By contrast, rental income earned by us does generally constitute passive income unless we are treated under specific rules as deriving our rental income in the active conduct of a trade or business.

While there are legal uncertainties involved in this determination, our counsel, Vinson & Elkins L.L.P., is of the opinion that we are not a PFIC based on certain representations that we have made to them regarding the composition of our assets, the source of our income, and the nature of our chartering activities and other operations following this offering, including:

•

all time charters we have entered into are substantially similar to those that we provided to Vinson & Elkins L.L.P.;

•

the estimated useful life of each of our vessels subject to a time charter will be 30 years from the date of delivery under the charter;

•

the total payments due to us under the charters are substantially in excess of the current bareboat charter rate for comparable vessels;

•

the income from our chartering activities with China Shipping/CSCL Asia, MOL, and COSCON will be greater than 25% of our total gross income at all relevant times; and

•

the gross value of our vessels chartered to China Shipping/CSCL Asia, MOL, and COSCON will exceed the gross value of all other assets we own at all relevant times.

In addition to these representations, the opinion of Vinson & Elkins L.L.P. that we are not a PFIC is based principally on the position that at least a majority, if not all, of the gross income we derive from our time chartering and voyage chartering activities should constitute services income, rather than rental income. Correspondingly, such services income should not constitute passive income, and the assets that we own and operate in connection with the production of such income, in particular, at least a majority, if not all, the vessels, should not constitute passive assets for purposes of determining whether we are a PFIC. Regarding this position, the opinion of Vinson & Elkins L.L.P. assumes that all future time charters that we will enter into are substantially similar to those we provided to them for their review. There is substantial legal authority supporting this position consisting of case law and IRS pronouncements concerning the characterization of income derived from time charters and voyage charters as services income for other tax purposes. However, in the absence of any legal authority specifically relating to the statutory provisions governing PFICs, the IRS or a court could disagree with this position and the opinion we have received from Vinson & Elkins L.L.P. In addition, there is no assurance that the nature of our assets, income and operations will remain the same in the future. Moreover, the market value of our stock may be treated as reflecting the value of our assets at any given time. Therefore, a decline in the market value of our stock (which is not within our control) may impact the determination of whether we are a PFIC.

As discussed more fully below, if we were to be treated as a PFIC for any taxable year during which a U.S. Holder owns shares, that U.S. Holder generally will be subject to special rules (regardless of whether we continue thereafter to be a PFIC). Such a U.S. Holder would be subject to different taxation rules depending on whether the U.S. Holder makes an election (a “QEF Election”) to treat us as a “Qualified Electing Fund.” As an alternative to making a QEF Election, a U.S. Holder should be able to make a “Mark-to-Market” election with respect to our common shares, as discussed below.

Taxation of U.S. Holders Making a Timely QEF Election

If a U.S. Holder makes a timely QEF Election, which U.S. Holder we refer to as an “Electing Holder,” the Electing Holder must report each year for U.S. federal income tax purposes his pro rata share of our ordinary earnings and our net capital gain, if any, for our taxable year that ends with or within the taxable year of the Electing Holder, regardless of whether or not distributions were received from us by the Electing Holder. The Electing Holder’s adjusted tax basis in the common shares will be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that had been previously taxed will result in a corresponding reduction in the adjusted tax basis in the common shares and will not be taxed again once distributed. An Electing Holder would generally recognize capital gain or loss on the sale, exchange or other disposition of our common shares. A U.S. Holder would make a QEF Election with respect to any year that we are a PFIC by filing one copy of IRS Form 8621 with his U.S. federal income tax return and a second copy in accordance with the instructions to such form.

Taxation of U.S. Holders Making a “Mark-to-Market” Election

Alternatively, if we were to be treated as a PFIC for any taxable year and, as we anticipate, our common shares were treated as “marketable stock,” a U.S. Holder would be allowed to make a “mark-to-market” election with respect to our common shares, provided the U.S. Holder completes and files IRS Form 8621 in accordance with the relevant instructions and related Treasury Regulations. If that election is made, the U.S. Holder generally would include as ordinary income in each taxable year the excess, if any, of the fair market value of the

common shares at the end of the taxable year over such holder’s adjusted tax basis in the common shares. The U.S. Holder would also be permitted an ordinary loss in respect of the excess, if any, of the U.S. Holder’s adjusted tax basis in the common shares over the fair market value thereof at the end of the taxable year, but only to the extent of the net amount previously included in income as a result of the mark-to-market election. A U.S. Holder’s tax basis in his common shares would be adjusted to reflect any such income or loss amount. Gain realized on the sale, exchange or other disposition of our common units would be treated as ordinary income, and any loss realized on the sale, exchange or other disposition of the common shares would be treated as ordinary loss to the extent that such loss does not exceed the net mark-to-market gains previously included by the U.S. Holder.

Taxation of U.S. Holders Not Making a Timely QEF or Mark-to-Market Election

Finally, if we were to be treated as a PFIC with respect to a U.S. Holder that does not make either a QEF Election or a Mark-to-Market Election (a “Non-Electing Holder”), such U.S. Holder would be subject to special rules with respect to (1) any excess distribution (i.e., the portion of any distributions received by the Non-Electing Holder on our common shares in a taxable year in excess of 125 percent of the average annual distributions received by the Non-Electing Holder in the three preceding taxable years, or, if shorter, the Non-Electing Holder’s holding period for the common shares), and (2) any gain realized on the sale, exchange or other disposition of our common shares. Under these special rules:

•

the excess distribution or gain would be allocated ratably over the Non-Electing Holder’s aggregate holding period for the common shares;

•

the amount allocated to the current taxable year and any taxable year prior to the year we were first treated as a PFIC with respect to the Non-Electing Holder would be taxed as ordinary income; and

•

the amount allocated to each of the other taxable years would be subject to tax at the highest rate of tax in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit would be imposed with respect to the resulting tax attributable to each such other taxable year.

If we are a PFIC and a Non-Electing Holder who is an individual dies while owning our shares, such holder’s successor generally would not receive a step-up in tax basis with respect to such shares.

United States Federal Income Taxation of Non-U.S. Holders

A beneficial owner of our common shares (other than a partnership or other entity or arrangement treated as a partnership or pass-through entity) that is not a U.S. Holder is a Non-U.S. Holder.

Distributions

Distributions we pay to a Non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax if the Non-U.S. Holder is not engaged in a U.S. trade or business. If the Non-U.S. Holder is engaged in a U.S. trade or business, distributions we pay will be subject to U.S. federal income tax if those distributions are effectively connected with that Non-U.S. Holder’s U.S. trade or business. However, distributions paid to a Non-U.S. Holder who is engaged in a trade or business may be exempt from taxation under an income tax treaty if the distributions are not attributable to a U.S. permanent establishment maintained by the Non-U.S. Holder.

Disposition of Shares

The U.S. federal income taxation of Non-U.S. Holders on any gain resulting from the disposition of our common shares is generally the same as described above regarding distributions. However, Non-U.S. Holders who are individuals can also be subject to tax on U.S. source gain resulting from the disposition of our common shares if they are present in the United States for 183 days or more during the taxable year in which those shares are disposed and meet certain other requirements.

Backup Withholding and Information Reporting

In general, dividend payments, other taxable distributions and proceeds of dispositions of our common shares paid to a U.S. Holder will be subject to information reporting requirements. Such payments or distributions to a non-corporate U.S. Holder also may be subject to backup withholding if the non-corporate U.S. Holder:

•

fails to provide an accurate taxpayer identification number;

•

is notified by the IRS that he has failed to report all interest or dividends required to be shown on his U.S. federal income tax returns; or

•

in certain circumstances, fails to comply with applicable certification requirements.

Non-U.S. Holders may be required to establish their exemption from information reporting and backup withholding by certifying their status on IRS Form W-8BEN, W-8ECI or W8-IMY, as applicable.

Backup withholding is not an additional tax. Rather, a taxpayer generally may obtain a refund of any amounts withheld under backup withholding rules that exceed such taxpayer’s U.S. federal income tax liability by filing a refund claim with the IRS.

NON-UNITED STATES TAX CONSEQUENCES

Marshall Islands Tax Consequences

The following discussion is the opinion of Dennis J. Reeder, Reeder & Simpson, P.C., our counsel as to matters of the laws of the Republic of the Marshall Islands, and the current laws of the Republic of the Marshall Islands applicable to persons who do not reside in, maintain offices in or engage in business in the Republic of the Marshall Islands.

Because we do not, and we do not expect that we will, conduct business or operations in the Republic of the Marshall Islands, and because all documentation related to this offering will be executed outside of the Republic of the Marshall Islands, under current Marshall Islands law you will not be subject to Marshall Islands taxation or withholding on distributions, including upon a return of capital, we make to you as a shareholder. In addition, you will not be subject to Marshall Islands stamp, capital gains or other taxes on the purchase, ownership or disposition of common shares, and you will not be required by the Republic of the Marshall Islands to file a tax return relating to the common shares.

Each prospective shareholder is urged to consult his tax counsel or other advisor with regard to the legal and tax consequences, under the laws of pertinent jurisdictions, including the Marshall Islands, of his investment in us. Further, it is the responsibility of each shareholder to file all state, local and non-U.S., as well as U.S. federal tax returns that may be required of him.

Canadian Federal Income Tax Consequences

The following discussion is the opinion of Bull, Housser & Tupper LLP, our counsel as to certain matters of Canadian law, as to the material Canadian federal income tax consequences under the Income Tax Act (Canada) (the Canada Tax Act), as of the date of this prospectus, that we believe are relevant to holders of common shares acquired in this offering who are, at all relevant times, for the purposes of the Canada Tax Act and the Canada-United States Tax Convention 1980 (the Canada-U.S. Treaty) resident only in the United States and who deal at arm’s length with us (U.S. Resident Holders).

Subject to the assumptions below, under the Canada Tax Act, no taxes on income (including taxable capital gains and withholding tax on dividends) are payable by U.S. Resident Holders in respect of the acquisition, holding, disposition or redemption of our shares. This opinion is based upon the assumptions that we are not a resident in Canada and such U.S. Resident Holders do not have, and have not had, for the purposes of the Canada-U.S. Treaty, a permanent establishment or fixed base in Canada to which such shares pertain and, in addition, do not use or hold and are not deemed or considered to use or hold such shares in the course of carrying on a business in Canada. We will not be resident in Canada in a taxation year if our principal business is the operation of ships that are used primarily in transporting passengers or goods in international traffic, all or substantially all of our gross revenue for the year consists of gross revenue from the operation of ships in transporting passengers or goods in that international traffic, and we were not granted articles of continuance in Canada before the end of the year. Income earned in Canada by a non-resident corporation from the operation of a ship in international traffic, and gains realized from the disposition of ships used principally in international traffic, are not included in a non-resident corporation’s income for Canadian tax purposes where the corporation’s country of residence grants substantially similar relief to a Canadian resident. For a further discussion, separate from this opinion, of the tax consequences of us becoming a resident in Canada, please read the section entitled “Risk Factors—Tax Risks” included in our most recent annual report on Form 20-F, which is incorporated herein by reference.

Each prospective shareholder is urged to consult his tax counsel or other advisor with regard to the legal and tax consequences, under the laws of pertinent jurisdictions, including Canada, of his investment in us. Further, it is the responsibility of each shareholder to file all state, local and non-U.S., as well as U.S. federal tax returns that may be required of him.

In addition, we may otherwise loan or pledge common shares to a financial institution or other third party that in turn may sell the common shares short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our common shares 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 shares may be deemed to be underwriters and any commissions received or profit realized by them on the resale of the shares may be deemed to be underwriting discounts and commissions under the Securities Act of 1933, as amended, or the Securities Act.

We may have agreements with agents, underwriters, dealers and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act. Agents, underwriters, dealers and remarketing firms, and their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business. This includes commercial banking and investment banking transactions.

At the time that any particular offering of common shares 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 common shares being offered, the purchase price of the common shares, the initial offering price of

the common shares, 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 reallowed or paid to dealers.

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 New York Stock Exchange, 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 all of the common shares being registered under this registration statement.

Pursuant to a requirement by the National Association of Securities Dealers, Inc., or NASD, the maximum commission or discount to be received by any NASD member or independent broker/dealer may not be greater than eight percent (8%) of the gross proceeds received by us for the sale of any common shares being registered pursuant to Commission Rule 415 under the Securities Act.
