PROSPECTUS SUPPLEMENT

(To Prospectus dated January 12, 2018)

Teekay Corporation

Common Stock

Having an Aggregate Offering Price of Up to $63,000,000

We have entered into an equity distribution agreement with Citigroup Global Markets Inc., or the “Agent,” relating to the shares of common stock of Teekay Corporation offered by this prospectus supplement and the accompanying prospectus. In accordance with the terms of the equity distribution agreement, we may offer and sell shares of common stock having an aggregate offering price of up to $63,000,000 from time to time through the Agent, as our sales agent, or directly to the Agent acting as principal.

Sales of the common stock, if any, made by the Agent, as our sales agent, as contemplated by this prospectus supplement and the accompanying prospectus, may be made by means of ordinary brokers’ transactions on the New York Stock Exchange at market prices, in block transactions, or as otherwise agreed between us and the Agent. We will pay the Agent a commission of up to 2.0% of the gross sales price per share of common stock sold through the Agent, as our sales agent, under the equity distribution agreement.

Under the terms of the equity distribution agreement, we also may sell shares of common stock to the Agent as principal at a price to be agreed upon at the time of sale. If we sell shares of common stock to the Agent as principal, we will enter into a separate terms agreement with the Agent, and we will describe the public offering price, underwriting discount (which may exceed 2.0% of the public offering price) and other terms of the offering of those shares of common stock in a separate prospectus supplement or pricing supplement.

The Agent is not required to sell any specific number of shares or dollar amount of our common stock but will use its reasonable efforts, as our sales agent, and on the terms and subject to the conditions of the equity distribution agreement, to sell the common stock offered on terms agreed by the Agent and us. The offering of shares of our common stock pursuant to the equity distribution agreement will terminate upon the earlier of (1) the sale of all of the common stock subject to the equity distribution agreement and (2) the termination of the equity distribution agreement by either the Agent or us.

Our common stock trades on the New York Stock Exchange (orNYSE) under the symbol “TK.” The last reported sale price of our common stock on the New York Stock Exchange on April 23, 2019 was $4.62 per share.

Investing in our common stock involves a high degree of risk. You should carefully consider each of the factors described or referred to under “Risk Factors” onpage S-8 of this prospectus supplement, page 4 of the accompanying prospectus and in the documents incorporated by reference into this prospectus supplement and accompanying prospectus before you make an investment in our common stock.

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

FORWARD-LOOKING STATEMENTS

All statements, other than statements of historical fact, included in or incorporated by reference into this prospectus are forward-looking statements. In addition, we and our representatives may from time to time make other oral or written statements that are also forward-looking statements. Such statements include, in particular, statements about our future or anticipated operations, cash flows, financial position, plans, strategies, business prospects, changes and trends in our business, and the markets in which we operate. In some cases, you can identify the forward-looking statements by the use of words such as “may,” “will,” “could,” “should,” “would,” “expect,” “plan,” “anticipate,” “intend,” “forecast,” “believe,” “estimate,” “predict,” “propose,” “potential,” “continue” or the negative of these terms or other comparable terminology.

These and other forward-looking statements reflect management’s current plans, expectations, estimates, assumptions and beliefs concerning future events affecting us. Forward-looking statements involve known and unknown risks and 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. We caution that forward- looking statements are not guarantees and that actual results may differ materially from those expressed or implied by such forward-looking statements. Important factors that could cause actual results to differ materially include, but are not limited to, those factors discussed under the heading “Risk Factors” set forth in this prospectus and those factors discussed in our most recent Annual Report on Form20-F and other reports we file with or furnish to the SEC and that are incorporated into this prospectus by reference.

We undertake no obligation to update any forward-looking statement to reflect any change in our expectations or events or circumstances that may arise after the date on which such statement is made. New factors emerge from time to time, and it is not possible for us to predict all of these factors. In addition, we cannot assess the effect of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement.

Forward-looking statements in this prospectus or incorporated by reference herein include, among others, statements about the following matters:

• the timing and amount of sales of our common stock pursuant to the equity distribution agreement, and the expected use of any sales proceeds;

• our plans for Teekay Parent (as defined below) not to have a direct ownership in any conventional tankers or floating production, storage andoff-loading (orFPSO) units, and increase its free cash flow, reduce its net debt and delever its balance sheet;

• our dividend policy and our payment of or our ability to pay any cash dividends on our shares of common stock, and the distribution and dividend policies of the Daughter Entities (as defined below), including the ability to increase the distribution levels of the Daughter Entities in the future;

• the completion, terms and pricing of the Note Offering (as defined below), and the collateral used to secure the Notes;

• commencement and results of the Tender Offer (as defined below), and the results of the Consent Solicitation (as defined below);

• our intent to cure the Teekay Tankers $1.00 per share deficiency and regain compliance with the NYSE continued listing requirement;

• our expectations regarding tax liabilities and classifications; and

• the realization of contracted, forward fixed-rate revenues.

SUMMARY

This summary highlights selected information contained elsewhere in this prospectus and the documents incorporated by reference in this prospectus and does not contain all the information you will need in making an investment decision.

Unless otherwise indicated, references in this prospectus to “Teekay,” the “Company,” “we,” “us” and “our” and similar terms refer to Teekay Corporation and/or its subsidiaries, except that those terms, when used in this prospectus in connection with the common stock described herein, shall mean specifically Teekay Corporation. References in this prospectus supplement to (a) “Teekay LNG” refer to Teekay LNG Partners L.P. (NYSE: TGP), a subsidiary of Teekay Corporation, (b) “Teekay Tankers” refer to Teekay Tankers Ltd.

(NYSE: TOO), an entity which since September 25, 2017 is no longer consolidated with Teekay Corporation and for which Teekay Corporation now accounts using the equity method. In this prospectus supplement, we refer to Teekay LNG and Teekay Tankers as the “Controlled Daughter Entities” and the Controlled Daughter Entities and Teekay Offshore collectively as the “Daughter Entities,” and references to the “Teekay group” include Teekay Parent and the Daughter Entities.

Unless otherwise indicated, certain information in this prospectus supplement about the vessels and fleets, segment market positions, employees, contracted revenues and related matters of the Teekay group or a particular group member refer in the aggregate to 100% of such items for (a) in the case of the Teekay group, Teekay Corporation, Teekay LNG, Teekay Tankers, Teekay Offshore and their subsidiaries and equity-accounted vessels and investments and (b) in the case of a particular Teekay group member, such member and its subsidiaries and equity-accounted vessels and investments.

Unless otherwise indicated, all references in this prospectus supplement to “dollars” and “$” are to, and amounts are presented in, U.S. Dollars.

Overview

The Teekay group is a leading provider of international crude oil and gas marine transportation services and offshore production and logistics with offices in 14 countries and approximately 8,000 seagoing and shore-based employees. The Teekay group provides these services primarily through:

• Teekay LNG – the world’s third largest independent owner and operator of LNG carriers;

�� Teekay Tankers – one of the world’s largest owners and operators ofmid-sized crude tankers; and

• Teekay Offshore – the world’s largest operator of shuttle tankers and fourth largest independent provider of leased FPSO unit solutions.¹

As of December 31, 2018, the Teekay group operated total assets under management of approximately $16 billion, comprised of approximately 205 liquefied gas, offshore, and conventional tanker assets (excluding vessels managed for third parties). The Teekay group generates revenue primarily under long-term, fixed-rate

¹  Teekay Offshore is controlled by Brookfield Business Partners L.P. and certain of its affiliates (collectively,Brookfield)

S-2

contracts with a diverse customer base of major energy and utility companies. As of January 1, 2019, the Teekay group had approximately $16 billion of contracted, forward fixed-rate revenues. The revenue-weighted average remaining term of the Teekay group’s contracts was approximately 8.4 years as of January 1, 2019, excluding spot market contracts and extension options. “Revenue-weighted average” represents the average remaining fixed contract duration of the applicable contracts, weighted on the basis of aggregate fixed forward payments to be received from each operating segment, excluding extension options. Fixed forward payments for Teekay Offshore are on a 100% basis and our equity accounted investments and joint ventures are proportionately adjusted in the calculation to reflect our ownership interests in such investments and joint ventures.

Background

Over the last two decades, we have undergone a major transformation from being primarily an owner of ships in the cyclical spot tanker business to being an asset manager and project developer in the “Marine Midstream” sector. This transformation has included the continuation and expansion of our liquefied natural gas (orLNG) business and our expansion into the liquefied petroleum gas (orLPG) shipping sector through Teekay LNG, the continuation and expansion of our conventional tanker business through Teekay Tankers, and expansion of our operations in the offshore production, storage and transportation sector primarily through our investment in Teekay Offshore.

Recent Developments

Teekay Parent

Concurrently with our signing of the equity distribution agreement, we separately announced:

• a proposed offering (theNote Offering) of $300,000,000 in aggregate principal amount of senior secured notes due 2024 (theNotes) in a private placement to eligible purchasers under Rule 144A and Regulation S of the U.S. Securities Act of 1933, as amended (theSecurities Act), which Notes will be guaranteed on a senior secured basis by certain of the Company’s subsidiaries and will initially be secured by first-priority liens, subject to permitted liens, on (i) two FPSO units (and related assets) owned by Company subsidiaries, (ii) all shares of common stock of the Company’s subsidiary that owns all of the Company’s common units of Teekay LNG and Teekay Offshore and all of the Company’s Class A common shares of Teekay Tankers and (iii) all equity interests in the Teekay subsidiaries that own two FPSO units;

• a proposed cash tender offer (theTender Offer) to purchase any and all of the Company’s outstanding 8.5% Senior Unsecured Notes due 2020 (the2020 Notes). Concurrently with the Tender Offer, the Company is soliciting (theConsent Solicitation) from the holders representing at least a majority of the aggregate principal amount of the 2020 Notes then outstanding a consent to certain proposed amendments that will eliminate substantially all of the restrictive covenants and certain events of default and related provisions from the indenture governing the 2020 Notes, including the covenant restricting the Company from granting liens on its assets for issuances of other debt securities unless the Company grants apari passulien on such assets in favor of the 2020 Notes; and

• that in connection with the Note Offering and the Tender Offer, Teekay’s Board of Directors has approved the elimination of the quarterly dividend on Teekay’s common stock, commencing with the dividend payable for the quarter ended March 31, 2019, in order to retain cash to further strengthen its balance sheet.

Teekay Tankers

In April 2019, Teekay Tankers received notice from the NYSE that Teekay Tankers is not in compliance with the NYSE continued listing standards because the average closing price of Teekay Tankers’ shares of

S-3

Class A common stock fell below $1.00 per share over a period of 30 consecutive trading days. In accordance with NYSE procedures, Teekay Tankers intends to cure the $1.00 per share deficiency and has six months following receipt of the noncompliance notice to regain compliance with the NYSE continued listing requirement.

Organizational structure and ownership in Daughter Entities

Our organizational structure can be divided into (a) our controlling interests in our publicly-listed subsidiaries, Teekay LNG and Teekay Tankers, (b) our equity-accounted investment in Teekay Offshore and (c) Teekay Parent.

The following chart provides an overview of our organizational structure as of April 1, 2019:

(1) Teekay LNG is controlled by its general partner. We indirectly own a 100% beneficial ownership in the general partner. However, in limited cases, approval of a majority of the unitholders of Teekay LNG is required to approve certain actions. Teekay LNG’s general partner owns its incentive distribution rights.

S-4

(2) Teekay Tankers has two classes of shares: Class A common stock and Class B common stock. We indirectly own 100% of the Class B shares through Teekay Holdings Limited, which have five votes each but aggregate voting power capped at 49%. As a result of our ownership of Class A and Class B shares, we hold aggregate voting power of 54.1% as of April 1, 2019.

(3) Teekay Offshore is controlled by its general partner. Brookfield and we indirectly have ownership interests of 51% and 49% of the general partner, respectively. However, in limited cases, approval of a majority of the unitholders of Teekay Offshore is required to approve certain actions. As a result of a transaction with Brookfield, since September 25, 2017, Teekay Offshore is no longer a consolidated subsidiary of ours, but is instead accounted for under the equity method. Teekay Offshore’s general partner owns its incentive distribution rights.

(4) Economic interests in Teekay LNG and Teekay Offshore are based on outstanding common units and common-unit equivalents represented by the general partner interests.

(5) Includes, among others, subsidiaries owning Teekay Parent’s three FPSO units.

Teekay Parent

Teekay Parent currently owns three FPSO units, two of which are on firm contracts to August and September 2020 and one of which is on alife-of-field contract. Teekay Parent is currently in discussions regarding and expects to obtain aone-year contract extension on thePetrojarl BanffFPSO unit to August 2020 and is currently in discussions with the charterers of the other two FPSO units on potential contract extensions and amendments or dispositions.

Our long-term vision is for Teekay Parent to be primarily a portfolio manager and project developer with the Teekay group’s fixed assets primarily owned directly by the Controlled Daughter Entities. Our primary financial objectives for Teekay Parent are to increase the value of the contracts for our three FPSO units and the value of our investments in Teekay LNG, Teekay Tankers and Teekay Offshore, increase Teekay Parent’s free cash flow and, as a service provider to the Daughter Entities, provide scale and other benefits across the Teekay group. We intend to (a) continue to reduce net debt of Teekay Parent, including by using the net proceeds from the potential sale of the three FPSO units or other assets in the future to repay debt and (b) seek to increase the distributions of Teekay LNG in a sustainable manner and the dividends of Teekay Tankers as the tanker market recovers.

Teekay LNG

Teekay LNG primarily provides LNG transportation services and includes all of our LNG andmid-size LPG carriers. LNG carriers are usually chartered to carry LNG pursuant to time-charter contracts, where a vessel is hired for a fixed period of time under atake-or-pay structure. LPG carriers are mainly chartered to carry LPG and ammonia ontake-or-pay time charter contracts, on contracts of affreightment or on spot voyage charters. As of April 1, 2019, Teekay LNG’s fleet of LNG carriers, including newbuildings on order, had a total cargo carrying capacity of approximately 8.0 million cubic meters.

Teekay LNG has a fleet of 79 vessels, including four newbuildings on order, and an interest in a regasification project in Bahrain. These four newbuildings and the regasification project are scheduled to commence operations under their respective long-term contracts in 2019. As of April 1, 2019, Teekay LNG had ownership interests ranging from 20% to 100% in 49 LNG carriers, including four newbuilding LNG carriers on order. In addition, Teekay LNG has 99% ownership interests in sevenmulti-gas carriers and 50% ownership interests, through its joint venture agreement with Exmar NV, in 22mid-size LPG carriers. Teekay LNG’s large and diverse portfolio of long-term contracts represented $10.1 billion of contracted, forward fixed-rate revenues with a revenue-weighted average remaining contract duration of approximately 11.5 years as of January 1, 2019 (excluding options to extend). Teekay’s LNG and LPG segments generated total consolidated revenues of $454.5 million and $23.9 million, respectively, in 2018 (which excludes revenue generated by vessels that are owned in equity-accounted joint ventures).

S-5

Teekay Tankers

Teekay Tankers provides oil transportation services and includes a substantial majority of our conventional crude oil tankers and all of our product carriers. Teekay Tankers’ conventional crude oil tankers and product tankers primarily operate in the spot-tanker market under contracts that are priced on a spot-market basis or under short-term, fixed-rate contracts. Teekay Tankers considers contracts that have an original term of less than one year in duration to be short-term. Certain of Teekay Tankers’ conventional crude oil tankers and product tankers are on fixed-ratetake-or-pay time-charter contracts with an initial duration of at least one year.

Teekay Tankers’ vessels compete primarily in the Aframax and Suezmax tanker markets. Many major oil companies and other oil trading companies, the primary charterers of our vessels, also operate their own vessels and transport their own oil and oil for third-party charterers in direct competition with us and other independent owners and operators. Teekay Tankers competes principally in the global spot-charter market.

As of April 1, 2019, Teekay Tankers’ fleet included 62 owned andchartered-in tankers (excluding sixship-to-ship transfer support vessels). Teekay Tankers also owns aship-to-ship transfer business that primarily provides lightering and reverse lightering services for crude oil imports into, and exports out of, the United States. As of April 1, 2019, Teekay Tankers’ fleet had a total cargo carrying capacity of approximately 8.5 million deadweight tonnes (ordwt).

Teekay Offshore

Teekay Offshore provides oil production and logistics services to the offshore oil production industry in the North Sea, Brazil and the East Coast of Canada and includes FPSO units, shuttle tankers, floating storage and offtake (orFSO) units, a unit for maintenance and safety (orUMS), and long-distance towing and offshore installation vessels. Teekay Offshore primarily provides FPSO and shuttle tanker services. Shuttle tankers generally operate under long-term, fixed-rate time-charter contracts or bareboat charter contracts for a specific offshore oil field (where a vessel is hired for a fixed period of time) or under contracts of affreightment to service various fields. FPSO units generally operate under long-term contracts — often where the contract’s duration is for the useful life of the oil field — and with a fixed charter rate and, in some cases, a variable component based on oil prices or production by the unit.

As of April 1, 2019, Teekay Offshore had interests in eight FPSO units, 35 shuttle tankers (including six newbuilding shuttle tankers on order), six FSO units, one UMS and 10 long-distance towing and offshore installation vessels. Teekay Offshore’s ownership interests in these vessels range from 50% to 100%. Teekay Offshore’s large and diverse portfolio of long-term contracts represented $5.7 billion of contracted, forward fixed-rate revenues with a revenue-weighted average remaining contract duration of approximately four years as of January 1, 2019 (excluding options to extend). Teekay Offshore has approximately 2,000 seagoing and shore-based employees.

Risk factors Investing in our common stock involves risks. You should carefully consider each of the factors described or referred to under “Risk Factors” beginning on pageS-8 of this prospectus supplement, page 4 of the accompanying prospectus and in the documents incorporated by reference into this prospectus supplement and accompanying prospectus before you make an investment in our common stock.

S-7

RISK FACTORS

An investment in our common stock involves risk. Before investing in our common stock, you should carefully consider the following risk factors, together with all the information included or incorporated by reference in this prospectus, including the risks discussed under the heading “Risk Factors” in the accompanying prospectus, in our latest Annual Report on Form20-F filed with the SEC and incorporated by reference into this prospectus supplement. For more information, please read “Where You Can Find More Information” in the prospectus and “Incorporation of Documents by Reference” in this prospectus supplement. In addition, you should read “Material United States Federal Income Tax Considerations” in this prospectus supplement and in the accompanying prospectus for a more complete discussion of expected material U.S. federal income tax consequences of owning and disposing of our securities.

If any of these risks were to occur, our business, financial condition, operating results or cash flows could be materially adversely affected. The risks and uncertainties we have described are not the only ones we face.

Additional risks and uncertainties that are not yet identified may also materially harm our business, financial condition, operating results and cash flows. In that case, the trading price of our common stock could decline, you could lose all or part of your investment and our ability to pay dividends on shares of our common stock may be reduced or restricted.

U.S. tax authorities could treat us as a “passive foreign investment company,” which could have adverse U.S. federal income tax consequences to U.S. shareholders.

Anon-U.S. entity treated as a corporation for U.S. federal income tax purposes will be treated as a “passive foreign investment company” (orPFIC) for such purposes in any taxable year for which either (a) at least 75% of its gross income consists of “passive income,” or (b) at least 50% of the average value of the entity’s assets is attributable to assets that produce or are held for the production of “passive income.” For purposes of these tests, “passive income” includes dividends, interest, gains from the sale or exchange of investment property and rents and royalties other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business. By contrast, income derived from the performance of services does not constitute “passive income.”

There are legal uncertainties involved in determining whether the income derived from our time-chartering activities constitutes rental income or income derived from the performance of services, including the decision in Tidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), which held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a foreign sales corporation provision of the Internal Revenue Code of 1986, as amended (or theCode). However, the Internal Revenue Service (or theIRS) stated in an Action on Decision (AOD2010-01) that it disagrees with, and will not acquiesce to, the way that the rental versus services framework was applied to the facts in the Tidewater decision, and in its discussion stated that the time charters at issue in Tidewater would be treated as producing services income for PFIC purposes. The IRS’s statement with respect to Tidewater cannot be relied upon or otherwise cited as precedent by taxpayers. Consequently, in the absence of any binding legal authority specifically relating to the statutory provisions governing PFICs, there can be no assurance that the IRS or a court would not follow the Tidewater decision in interpreting the PFIC provisions of the Code. Nevertheless, based on the current composition of our assets and operations (and those of our look-through subsidiaries), we intend to take the position that we are not now and have never been a PFIC, and our counsel, Perkins Coie LLP, is of the opinion that it is more likely than not we are not a PFIC based on representations we have made to them regarding the composition of our and our look-through subsidiaries’ assets, source of income and nature of activities and operations. No assurance can be given, however, that the opinion of Perkins Coie LLP would be sustained by a court if contested by the IRS, or that we would not constitute a PFIC for any future taxable year if there were to be changes in our assets, income or operations.

S-8

If the IRS were to determine that we are or have been a PFIC for any taxable year during which a U.S. Holder (as defined below under “Material United States Federal Income Tax Considerations”) held stock, such U.S. Holder would face adverse U.S. federal income tax consequences. For a more comprehensive discussion regarding our status as a PFIC and the tax consequences to U.S. Holders if we are treated as a PFIC, please read “Material United States Federal Income Tax Considerations — United States Federal Income Taxation of U.S. Holders — Consequences of Possible PFIC Classification.”

We may be subject to taxes, which reduces our cash available for distribution to our shareholders.

We or some of our subsidiaries may be subject to tax in the jurisdictions in which we or our subsidiaries are organized or operate, reducing the amount of our cash available for distribution. In computing our tax obligation in these jurisdictions, we are required to take various tax accounting and reporting positions on matters that are not entirely free from doubt and for which we have not received rulings from the governing authorities. We cannot assure you that upon review of these positions the applicable authorities will agree with our positions. A successful challenge by a tax authority could result in additional tax imposed on us or our subsidiaries in jurisdictions in which operations are conducted. For example, if Teekay Corporation was not able to meet the criteria specified by Section 883 of the Code, our U.S. source income may become subject to taxation.

Teekay Tankers currently is not in compliance with the NYSE’s requirements for the continued listing of its Class A common stock on the exchange, which may adversely affect the value of shares of such stock owned by us.

Teekay Tankers’ Class A common stock is listed on the NYSE under the symbol “TNK”. On April 10, 2019, Teekay Tankers received written notice from the NYSE that Teekay Tankers is not in compliance with the NYSE continued listing standards because the average closing price of Teekay Tankers’ shares of Class A common stock fell below $1.00 per share over a period of 30 consecutive trading days. Teekay Tankers intends to cure the $1.00 per share deficiency and has six months following receipt of the noncompliance notice to regain compliance with the NYSE continued listing requirement. If Teekay Tankers fails to timely cure the noncompliance, the NYSE would delist the Class A common stock from the NYSE. Any such delisting would negatively impact Teekay Tankers and holders of the Class A common stock, including due to the resulting decreased price, liquidity and trading of the Class A common stock, limited availability of price quotations and reduced news and analyst coverage. These developments may also require brokers trading in the Class A common stock to adhere to more stringent rules and may limit Teekay Tankers’ ability to raise capital by issuing additional shares of Class A common stock in the future. Delisting may adversely impact the perception of Teekay Tankers’ financial condition and harm its reputation with investors and other third parties. In addition, any perceived decrease in value of employee equity incentive awards may reduce their effectiveness in encouraging performance and retention.

USE OF PROCEEDS

We intend to use the net proceeds from this offering of shares of our common stock, if any, after deducting the Agent’s commission and our offering expenses, for general corporate purposes, which may include, among other things, repaying a portion of our outstanding indebtedness.

DESCRIPTION OF CAPITAL STOCK

General

We may issue common stock or preferred stock, in one or more distinct series, from time to time. This section summarizes the material terms of our common stock and material terms that would be common to all series of our preferred stock. The following description of our common stock, preferred stock and provisions of our Amended and Restated Articles of Incorporation, as amended (or Articles) and our Amended and Restated Bylaws (or Bylaws), are summaries and are qualified by reference to our Articles and our Bylaws, copies of which have been filed as exhibits to our Annual Report on Form 20-F for the year ended December 31, 2018, which is incorporated by reference herein.

Our authorized capital stock consists of 725 million shares of common stock, with a par value of $0.001 per share, and 25 million shares of preferred stock, with a par value of $1 per share. As of April 22, 2019, there were 100,684,489 shares of our common stock outstanding and no shares of preferred stock outstanding.

Exchange Listing

Shares of our common stock are listed on the New York Stock Exchange, where they trade under the symbol “TK.”

Transfer Agent and Registrar

Computershare Inc. serves as registrar and transfer agent for our common stock.

Common Stock

Each outstanding share of our common stock entitles the holder to one vote on all matters submitted to a vote of shareholders. Subject to preferences that may be applicable to any outstanding shares of our preferred stock, holders of common stock are entitled to receive ratably any dividends declared from time to time by our Board of Directors out of funds legally available therefor. Holders of our common stock generally do not have conversion, redemption or preemptive rights to subscribe for any of our securities. All outstanding shares of common stock are fully paid and nonassessable. The rights, preferences and privileges of holders of our common stock are subject to the rights of the holders of any shares of preferred stock that we may issue.

Preferred Stock

Our Board of Directors may from time to time, and without further action by our shareholders, direct the issuance of shares of preferred stock in one or more series and may, at the time of issuance, determine the rights, preference and limitations of each such series. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of common stock. Holders of shares of our preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of Teekay Corporation before any payment is made to the holders of shares of our common stock. The voting, dividend, liquidation, redemption, conversion or other rights of any preferred stock we may issue could adversely affect the voting power and other rights of the holders of our common stock and may have the effect of decreasing the market price of our common stock. Under certain circumstances, the issuance of shares of our preferred stock may render more difficult or tend to discourage a merger, tender offer, proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management.

S-12

Anti-Takeover Provisions

Preferred Stock Authorization

As noted above, our Board of Directors, without shareholder approval, has the authority under our Articles to issue preferred stock with rights superior to the rights of the holders of common stock. As a result, preferred stock could be issued quickly and easily, could adversely affect the rights of holders of common stock and could be issued with terms calculated or which have a tendency to delay or prevent a change of control of Teekay Corporation or make removal of management more difficult.

Shareholder Rights Plan

We have an amended and restated shareholders rights agreement pursuant to which holders of our common stock have been granted one purchase right on each outstanding share of common stock. Each purchase right, when exercisable, initially entitles its registered holder to purchase from us one share of our common stock at a price of $200 per share, subject to certain anti-dilution adjustments. The purchase rights are not currently exercisable and will become exercisable only upon the earlier of:

• Ten days following a public announcement that a person became an “acquiring person,” which refers to a person who either (a) did not beneficially own 15% or more of our outstanding common stock on July 2, 2010 (the effective date of the amended and restated shareholder rights plan), and subsequently acquires beneficial ownership of 20% or more of our outstanding common stock, or (b) did beneficially own 15% or more of our outstanding common stock on July 2, 2010, and subsequently acquires beneficial ownership of an additional 5% or more of our outstanding common stock; or

• Ten business days (or such later date as may be determined by action of the Board of Directors prior to such time as any person or group of affiliated persons becomes an acquiring person) following the commencement of, or announcement of an intention to make, a tender offer or exchange offer the consummation of which would result in a person or group becoming an acquiring person.

Unless otherwise approved by our Board of Directors, if a person becomes an acquiring person, the purchase rights held at any time by the acquiring person and its affiliates will become null and void and nontransferable, and the remaining purchase rights will entitle each other right holder to purchase, for the purchase price, the number of shares of our common stock which at the time of the transaction would have a market value equal to twice the purchase price. Additionally, at any time prior to an acquiring person’s becoming the holder of 50% or more of our outstanding shares of common stock, our Board of Directors may exchange the purchase rights (other than the purchase rights owned by the acquiring person and its affiliates), at an exchange ratio of one share of our common stock per purchase right.

After a person becomes an acquiring person, each of the following events would entitle each holder of a purchase right (other than the acquiring person and its affiliates) to purchase, for the purchase price, that number of shares of common stock of another corporation which at the time of the event would have a market value equal to twice the purchase price:

• the acquisition of us in a merger by such other corporation;

• a business combination between us and such other corporation; or

• the sale, lease, exchange or transfer of 50% or more of our assets or assets accounting for 50% or more of our net income or revenues, in one or more transactions.

At any time prior to the earlier of a triggering offer or any person becoming an acquiring person, our Board of Directors may redeem the purchase rights in whole, but not in part, at a price of $0.0001 per purchase right. In addition, the Board of Directors may also waive, within a specified period, the effect of such triggering event or a person being an acquiring person.

S-13

The purchase rights have certain anti-takeover effects and will cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our Board of Directors. The purchase rights will not interfere with any merger or other business combination approved by our Board of Directors, since the Board of Directors may, at its option, authorize Teekay Corporation to redeem all of the then-outstanding purchase rights or waive the application of the shareholder rights plan in connection with a specific transaction. The shareholder rights plan and the rights expire in July 2020. The description and terms of the purchase rights are set forth in our Amended and Restated Rights Agreement that is filed as an exhibit to the Registration Statement onForm 8-A/A filed on July 2, 2010, which is incorporated by reference into this prospectus.

Shareholder Meetings, Quorum, and Voting

Our Bylaws establish advance notice procedures with respect to business brought before an annual meeting by a shareholder and the nomination of candidates for election as directors, other than nominations made by or at the direction of our Board of Directors. Under our Bylaws, special meetings of the shareholders may be called only by our Board of Directors. No business other than that stated in the notice of meeting may be transacted at any special meeting. Our Articles provide that a majority of the shares entitled to vote on any matter shall constitute a quorum at a meeting of shareholders, unless the matter has been submitted to the shareholders at any meeting and recommended by a majority of our Continuing Directors (as defined in our Articles), in which case one-third of the shares entitled to vote on the matter shall constitute a quorum.

Election of Directors

Our Bylaws provide for a “staggered board,” with our Board of Directors divided into three classes, as nearly equal in number as possible, and the directors in each class serving three-year terms and one class being elected each year by our shareholders. Vacancies on the Board of Directors are filled by our Board of Directors. Because this system of electing directors and filling vacancies generally makes it more difficult for shareholders to replace a majority of the Board of Directors, it may tend to discourage a third party from making a tender offer or otherwise attempting to gain control of us.

Other Matters

Sales of Assets, Mergers and Dissolution

Under the Marshall Islands Business Corporations Act, the sale, lease, exchange or other disposition of all or substantially all of Teekay Corporation’s assets not made in the usual or regular course of Teekay Corporation’s business or the non-judicial dissolution and liquidation of Teekay Corporation are required to be approved by the holders of two-thirds of the outstanding shares of our capital stock entitled to vote on such matter; in addition, non-judicial dissolution approved, if approved by written consent, must be approved by a unanimous written consent of all holders of capital stock entitled to vote on the matter. In addition, the holders of one-half of the outstanding shares of capital stock entitled to vote in an election of directors may institute judicial dissolution proceedings in specified circumstances in accordance with the Marshall Islands Business Corporations Act. In the event of the dissolution of Teekay Corporation, the holders of our common stock will be entitled to share pro rata in our net assets available for distribution to them, after payment to all creditors and the liquidation preferences of any of our outstanding preferred stock.

Under the Marshall Islands Business Corporations Act, a merger or consolidation involving Teekay Corporation (other than with certain subsidiaries at least 90% of whose shares of each class are owned by Teekay Corporation) is required to be approved by the holders of a majority of the outstanding shares of our capital stock entitled to vote on the matter.

A class of shares may be entitled to vote separately as a class on various corporate activities. The vote for such class will be determined by the Marshall Islands Business Corporations Act and, if applicable, our articles of incorporation and bylaws.

S-14

Dissenters’ Rights of Appraisal and Payment

Under the Marshall Islands Business Corporations Act, shareholders have the right to dissent from various corporate actions, including certain mergers or sales, leases, exchanges or other dispositions 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. The right of a dissenting shareholder to receive payment of the fair value of such shareholder’s shares shall not be available for the shares of any class or series of stock, which shares, at the record date fixed to determine the shareholders entitled to receive notice of and to vote at the meeting of shareholders to act upon the agreement of merger or consolidation or any sale or exchange of all or substantially all of the property and assets of the corporation not made in the usual course of its business, were either (i) listed on a securities exchange or admitted for trading on an interdealer quotation system or (ii) held of record by more than 2,000 holders. 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, creates or abolishes certain rights in respect of those shares. A condition for such payment is that the dissenting shareholders follow the procedures set forth in the Marshall Islands Business Corporations Act. In the event that we (or the surviving entity in a merger) fail to agree with any dissenting shareholder on a price for the shares, such procedures involve, among other things, the institution of court proceedings in either the Republic of the Marshall Islands or the country where our shares are primarily traded, which is the United States. The value of the shares of a dissenting shareholder is fixed by the court after reference, if the court so elects, to the recommendations of a court-appointed appraiser.

Amendment of Articles of Incorporation

Under the Marshall Islands Business Corporations Act, amendments to the articles of incorporation of a Republic of the Marshall Islands corporation generally may be authorized upon approval of the holders of a majority of all outstanding shares entitled to vote. The approval of the holders of a majority of the outstanding shares of an adversely affected class or series of stock is also required for certain amendments.

Limitations on Ownership and Dividends

Neither Republic of the Marshall Islands law nor our Articles or Bylaws limit the right to own our securities, including the rights of non-resident or foreign shareholders to hold or exercise voting rights on the securities. Certain of our debt facilities, and Republic of the Marshall Islands law, impose limitations on our ability to pay dividends.

S-15

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of the material U.S. federal income tax considerations that may be relevant to prospective shareholders and, unless otherwise noted in the following discussion, is the opinion of Perkins Coie LLP, 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 the provisions of the Code, legislative history, applicable U.S. Treasury Regulations (orTreasury Regulations), judicial authority and administrative interpretations, all as in effect on the date of this prospectus, and which are subject to change, possibly with retroactive effect, or are subject to different interpretations. 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 Teekay Corporation.

This discussion is limited to shareholders who hold their common stock as a capital asset for tax purposes. This discussion does not address all tax considerations that may be important to a particular shareholder in light of the shareholder’s circumstances, or to certain categories of shareholders that may be subject to special tax rules, such as:

• dealers in securities or currencies;

• traders in securities that have elected themark-to-market method of accounting for their securities;

• persons whose functional currency is not the U.S. dollar;

• persons holding our common stock as part of a hedge, straddle, conversion or other “synthetic security” or integrated transaction;

• certain U.S. expatriates;

• financial institutions;

• insurance companies;

• persons subject to the alternative minimum tax;

• persons that actually or under applicable constructive ownership rules own 10% or more of our stock (by vote or value); and

• entities that aretax-exempt for U.S. federal income tax purposes.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. Partners in partnerships holding our common stock should consult their tax advisors to determine the appropriate tax treatment of the partnership’s ownership of our common stock.

No ruling has been or will be requested from the IRS regarding any matter affecting us or our shareholders. Instead, we will rely on the opinion of Perkins Coie LLP. Unlike a ruling, an opinion of counsel represents only that counsel’s legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made herein may not be sustained by a court if contested by the IRS.

This discussion does not address any U.S. estate tax considerations or tax considerations arising under the laws of any state, local ornon-U.S. jurisdiction. Each shareholder is urged to consult its tax advisor regarding the U.S. federal, state, local,non-U.S. and other tax consequences of the ownership or disposition of our common stock.

United States Federal Income Taxation of U.S. Holders

As used herein, the termU.S. Holder means a beneficial owner of our common stock that is, for U.S. federal income tax purposes: (a) a U.S. citizen or U.S. resident alien (or aU.S. Individual Holder), (b) a corporation or

S-16

other entity taxable as a corporation that was created or organized under the laws of the United States, any state thereof or the District of Columbia, (c) an estate whose income is subject to U.S. federal income taxation regardless of its source, or (d) a trust that either is subject to the supervision of a court within the United States and has one or more U.S. persons with authority to control all of its substantial decisions or has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

Distributions

Subject to the discussion of passive foreign investment companies (orPFICs) below, any distributions made by us to a U.S. Holder generally will 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 current and accumulated 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 our common stock and thereafter as capital gain, which will be either long term or short term capital gain depending upon whether the U.S. Holder has held the common stock for more than one year. U.S. Holders that are corporations for U.S. federal income tax purposes generally will not be entitled to claim a dividends received deduction with respect to any distributions they receive from us. For purposes of computing allowable foreign tax credits for U.S. federal income tax purposes, dividends received with respect to our common stock will be treated as foreign source income and generally will be treated as “passive category income”.

Subject to holding period requirements and certain other limitations, dividends received with respect to our common stock by a U.S. Holder who is an individual, trust or estate (aNon-Corporate U.S. Holder) will be treated as “qualified dividend income” that is taxable to suchNon-Corporate U.S. Holder at preferential capital gain tax rates provided that we are not classified as a PFIC for the taxable year during which the dividend is paid or the immediately preceding taxable year (we intend to take the position that we are not now and have never been classified as a PFIC, as discussed below). Any dividends received with respect to our common stock not eligible for these preferential rates will be taxed as ordinary income to aNon-Corporate U.S. Holder.

Special rules may apply to any “extraordinary dividend” paid by us. Generally, an extraordinary dividend is a dividend with respect to a share of common stock if the amount of the dividend is equal to or in excess of 10% of a common stockholder’s adjusted tax basis (or fair market value in certain circumstances) in such common stock. In addition, extraordinary dividends include dividends received within a one year period that, in the aggregate, equal or exceed 20% of a stockholder’s adjusted tax basis (or fair market value in certain circumstances). If we pay an “extraordinary dividend” on our common stock that is treated as “qualified dividend income,” then any loss recognized by aNon-Corporate U.S. Holder from the sale or exchange of such common stock will be treated as long-term capital loss to the extent of the amount of such dividend.

CertainNon-Corporate U.S. Holders are subject to a 3.8% tax on certain investment income, including dividends.Non-Corporate U.S. Holders should consult their tax advisors regarding the effect, if any, of this tax on their ownership of our common stock.

Sale, Exchange or Other Disposition of Common Stock

Subject to the discussion of PFICs below, a U.S. Holder generally will recognize capital gain or loss upon a sale, exchange or other disposition of our common stock 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 stock. Subject to the discussion of extraordinary dividends above, such gain or loss generally will be treated as (a) 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, or short term capital gain or loss otherwise and (b) U.S. source gain or loss, as applicable, for foreign tax credit purposes.Non-Corporate U.S. Holders may be eligible for preferential

S-17

rates of U.S. federal income tax in respect of long-term capital gains. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations.

CertainNon-Corporate U.S. Holders are subject to a 3.8% tax on certain investment income, including capital gains from the sale or other disposition of stock.Non-Corporate U.S. Holders should consult their tax advisors regarding the effect, if any, of this tax on their disposition of our common stock.

Consequences of Possible PFIC Classification

Anon-U.S. entity treated as a corporation for U.S. federal income tax purposes will be treated as a PFIC in any taxable year in which, after taking into account the income and assets of the corporation and, pursuant to a “look through” rule, any other corporation in which the corporation directly or indirectly owns at least 25% of the stock (by value), either: (a) at least 75% of its gross income is “passive” income; or (b) at least 50% of the average value of its assets is attributable to assets that produce or are held for the production of passive income. For purposes of these tests, “passive income” includes dividends, interest, gains from the sale or exchange of investment property and rents and royalties (other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business). By contrast, income derived from the performance of services does not constitute “passive income.”

There are legal uncertainties involved in determining whether the income derived from our time-chartering activities constitutes rental income or income derived from the performance of services, including legal uncertainties arising from the decision inTidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), which held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a foreign sales corporation provision of the Code. However, the IRS stated in an Action on Decision (AOD2010-01) that it disagrees with, and will not acquiesce to, the way that the rental versus services framework was applied to the facts in theTidewaterdecision, and in its discussion stated that the time charters at issue inTidewaterwould be treated as producing services income for PFIC purposes. The IRS’s statement with respect toTidewatercannot be relied upon or otherwise cited as precedent by taxpayers. Consequently, in the absence of any binding legal authority specifically relating to the statutory provisions governing PFICs, there can be no assurance that the IRS or a court would not follow theTidewaterdecision in interpreting the PFIC provisions of the Code. Moreover, the market value of our common stock and our publicly traded subsidiaries may be treated as reflecting the value of our assets, and our publicly traded subsidiaries’ assets, respectively, at any given time. Therefore, a decline in the market value of our common stock, or our publicly traded subsidiaries, which is not within our control, may impact the determination of whether we are a PFIC. Nevertheless, based on our and our look-through subsidiaries’ current assets and operations, we intend to take the position that we are not now and have never been a PFIC, and our counsel, Perkins Coie LLP, is of the opinion that it is more likely than not that we are not a PFIC based on applicable law, including the Code, legislative history, published revenue rulings and court decisions, and representations we have made to them regarding the composition of our and our look-through subsidiaries’ assets, source of income and nature of activities and other operations, including:

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

the income derived from our participation in pooling arrangements and from our other time and voyage charters will be greater than 25% of our total gross income at all relevant times; and

the gross value of our vessels participating in pooling arrangements and servicing our other time and voyage charters will exceed the gross value of all other assets we own at all relevant times.

An opinion of counsel represents only that counsel’s best legal judgment and does not bind the IRS or the courts. Accordingly, the opinion of Perkins Coie LLP may not be sustained by a court if contested by the IRS. Further, no assurance can be given that we would not constitute a PFIC for any future taxable year if there were to be changes in our or our subsidiaries’ assets, income or operations.

S-18

As discussed more fully below, if we were to be treated as a PFIC for any taxable year, a U.S. Holder generally would be subject to different taxation rules depending on whether the U.S. Holder makes a timely and effective election to treat us as a “Qualified Electing Fund” (or aQEF election). 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 stock, as discussed below.

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

A U.S. Holder who makes a timely QEF election (anElecting Holder) must report the Electing Holder’s pro rata share of our ordinary earnings and net capital gain, if any, for each taxable year for which we are a PFIC that ends with or within the Electing Holder’s taxable year, regardless of whether or not the Electing Holder received distributions from us in that year. Such income inclusions would not be eligible for the preferential tax rates applicable to qualified dividend income. The Electing Holder’s adjusted tax basis in our common stock will be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that were previously taxed will result in a corresponding reduction in the Electing Holder’s adjusted tax basis in our common stock and will not be taxed again once distributed. An Electing Holder generally will recognize capital gain or loss on the sale, exchange or other disposition of our common stock. A U.S. Holder makes a QEF election with respect to any year that we are a PFIC by filing IRS Form 8621 with the U.S. Holder’s timely filed U.S. federal income tax return (including extensions).

If a U.S. Holder has not made a timely QEF election with respect to the first year in the U.S. Holder’s holding period of our common stock during which we qualified as a PFIC, the U.S. Holder may be treated as having made a timely QEF election by filing a QEF election with the U.S. Holder’s timely filed U.S. federal income tax return (including extensions) and, under the rules of Section 1291 of the Code, a “deemed sale election” to include in income as an “excess distribution” (described below) the amount of any gain that the U.S. Holder would otherwise recognize if the U.S. Holder sold the U.S. Holder’s common stock on the “qualification date.” The qualification date is the first day of our taxable year in which we qualified as a “qualified electing fund” with respect to such U.S. Holder. In addition to the above rules, under very limited circumstances, a U.S. Holder may make a retroactive QEF election if the U.S. Holder failed to file the QEF election documents in a timely manner. If a U.S. Holder makes a timely QEF election for one of our taxable years, but did not make such election with respect to the first year in the U.S. Holder’s holding period of our common stock during which we qualified as a PFIC and the U.S. Holder did not make the deemed sale election described above, the U.S. Holder also will be subject to the more adverse rules described below.

A U.S. Holder’s QEF election will not be effective unless we annually provide the U.S. Holder with certain information concerning our income and gain, calculated in accordance with the Code, to be included with the U.S. Holder’s U.S. federal income tax return. We have not provided our U.S. Holders with such information in prior taxable years and do not intend to provide such information in the current taxable year. Accordingly, U.S. Holders will not be able to make an effective QEF election at this time. If, contrary to our expectations, we determine that we are or will be a PFIC for any taxable year, we will provide U.S. Holders with the information necessary to make an effective QEF election with respect to our common stock.

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

If we were to be treated as a PFIC for any taxable year and, as we anticipate, our common stock was treated as “marketable stock,” then, as an alternative to making a QEF election, a U.S. Holder would be allowed to make a“mark-to-market” election with respect to our common stock, 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 for the first year a U.S. Holder holds or is deemed to hold our common stock and for which we are a PFIC, the U.S. Holder generally would include as ordinary income in each taxable year that we are a PFIC the excess, if any, of the fair market value of the U.S. Holder’s common stock at the end of the taxable year over the U.S. Holder’s adjusted tax basis in the common stock. The U.S. Holder also would be permitted an ordinary loss in

S-19

respect of the excess, if any, of the U.S. Holder’s adjusted tax basis in the common stock over the fair market value thereof at the end of the taxable year that we are a PFIC, but only to the extent of the net amount previously included in income as a result of themark-to-market election. A U.S. Holder’s tax basis in our common stock would be adjusted to reflect any such income or loss recognized. Gain recognized on the sale, exchange or other disposition of our common stock in taxable years that we are a PFIC would be treated as ordinary income, and any loss recognized on the sale, exchange or other disposition of our common stock in taxable years that we are a PFIC would be treated as ordinary loss to the extent that such loss does not exceed the netmark-to-market gains previously included in income by the U.S. Holder. Because themark-to-market election only applies to marketable stock, however, it would not apply to a U.S. Holder’s indirect interest in any of our subsidiaries that were also determined to be PFICs.

If a U.S. Holder makes amark-to-market election for one of our taxable years and we were a PFIC for a prior taxable year during which such U.S. Holder held our common stock and for which (a) we were not a QEF with respect to such U.S. Holder and (b) such U.S. Holder did not make a timelymark-to-market election, such U.S. Holder would also be subject to the more adverse rules described below in the first taxable year for which themark-to-market election is in effect and also to the extent the fair market value of the U.S. Holder’s common stock exceeds the U.S. Holder’s adjusted tax basis in the common stock at the end of the first taxable year for which themark-to-market election is in effect.

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

If we were to be treated as a PFIC for any taxable year, a U.S. Holder who does not make either a QEF election or a“mark-to-market” election for that year (aNon-Electing Holder) would be subject to special rules resulting in increased tax liability with respect to (a) any “excess distribution” (i.e., the portion of any distributions received by theNon-Electing Holder on our common stock in a taxable year in excess of 125% of the average annual distributions received by theNon-Electing Holder in the three preceding taxable years, or, if shorter, theNon-Electing Holder’s holding period for our common stock), and (b) any gain realized on the sale, exchange or other disposition of our common stock. Under these special rules:

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

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

the amount allocated to each of the other taxable years would be subject to U.S. federal income 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.

Additionally, for each year during which a U.S. Holder holds our common stock, we are a PFIC, and the total value of all PFIC stock that such U.S. Holder directly or indirectly holds exceeds certain thresholds, such U.S. Holder will be required to file IRS Form 8621 with its annual U.S. federal income tax return to report its ownership of our common stock. In addition, if aNon-Electing Holder who is an individual dies while owning our common stock, suchNon-Electing Holder’s successor generally would not receive astep-up in tax basis with respect to such common stock.

S-20

U.S. Holders are urged to consult their tax advisors regarding the PFIC rules, including the PFIC annual reporting requirements, as well as the applicability, availability and advisability of, and procedure for, making QEF,mark-to-market and other available elections with respect to us and our subsidiaries, and the U.S. federal income tax consequences of making such elections.

U.S. Return Disclosure Requirements for U.S. Individual Holders

U.S. Individual Holders who hold certain specified foreign financial assets, including stock in a foreign corporation that is not held in an account maintained by a financial institution, with an aggregate value in excess of $50,000 on the last day of a taxable year, or $75,000 at any time during that taxable year, may be required to report such assets on IRS Form 8938 with their U.S. federal income tax return for that taxable year. This reporting requirement does not apply to U.S. Individual Holders who report their ownership of our common stock under the PFIC annual reporting rules described above. Penalties apply for failure to properly complete and file IRS Form 8938. U.S. Individual Holders are encouraged to consult with their tax advisors regarding the possible application of this disclosure requirement to their investment in our common stock.

United States Federal Income Taxation ofNon-U.S. Holders

A beneficial owner of our common stock (other than a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder is aNon-U.S. Holder.

Distributions

In general, aNon-U.S. Holder will not be subject to U.S. federal income tax on distributions received from us with respect to our common stock unless the distributions are effectively connected with theNon-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment that theNon-U.S. Holder maintains in the United States). If aNon-U.S. Holder is engaged in a trade or business within the United States and the distributions are deemed to be effectively connected to that trade or business (and, if required by an applicable income tax treaty, are attributable to a permanent establishment that theNon-U.S. Holder maintains in the United States), theNon-U.S. Holder generally will be subject to U.S. federal income tax on those distributions in the same manner as if it were a U.S. Holder. In addition, aNon-U.S. Holder that is a foreign corporation for U.S. federal income tax purposes may be subject to branch profits tax at a rate of 30% (or lower applicable treaty rate) on theafter-tax earnings and profits attributable to such distributions.

Sale, Exchange or Other Disposition of Common Stock

In general, aNon-U.S. Holder is not subject to U.S. federal income tax on any gain resulting from the disposition of our common stock unless (a) such gain is effectively connected with theNon-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment that theNon-U.S. Holder maintains in the United States) or (b) theNon-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year in which such disposition occurs and meets certain other requirements. If aNon-U.S. Holder is engaged in a trade or business within the United States and the disposition of our common stock is deemed to be effectively connected to that trade or business (and, if required by an applicable income tax treaty, are attributable to a permanent establishment that theNon-U.S. Holder maintains in the United States), theNon-U.S. Holder generally will be subject to U.S. federal income tax on the resulting gain in the same manner as if it were a U.S. Holder. In addition, aNon-U.S. Holder that is a foreign corporation for U.S. federal income tax purposes may be subject to branch profits tax at a rate of 30% (or lower applicable treaty rate) on theafter-tax earnings and profits attributable to such gain.

S-21

Information Reporting and Backup Withholding

In general, distributions taxable as dividends with respect to, or the proceeds from a sale, redemption or other taxable disposition of, our common stock held by a Non–Corporate U.S. Holder will be subject to information reporting requirements, unless such distribution taxable as a dividend is paid and received outside the United States by anon-U.S. payor ornon-U.S. middleman (within the meaning of U.S. Treasury Regulations), or such proceeds are effected through an office outside the U.S. of a broker that is considered anon-U.S. payor ornon-U.S. middleman (within the meaning of U.S. Treasury Regulations). These amounts also generally will be subject to backup withholding if the Non-Corporate U.S. Holder:

• fails to timely provide an accurate taxpayer identification number;

• is notified by the IRS that it has failed to report all interest or distributions required to be shown on its U.S. federal income tax returns; or

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

Information reporting and backup withholding generally will not apply to distributions taxable as dividends on our common stock to a Non-U.S. Holder if such dividend is paid and received outside the United States by anon-U.S. payor ornon-U.S. middleman (within the meaning of U.S. Treasury Regulations) or theNon-U.S. Holder properly certifies under penalties of perjury as to itsnon-U.S. status (generally on IRS FormW-8BEN,W-8BEN-E,W-8ECI,W-8EXP orW-8IMY, as applicable) and certain other conditions are met or theNon-U.S. Holder otherwise establishes an exemption.

Payment of proceeds to aNon-U.S. Holder from a sale, redemption or other taxable disposition of our common stock to or through the U.S. office of a broker, or through a broker that is considered a U.S. payor or U.S. middleman (within the meaning of U.S. Treasury Regulations), generally will be subject to information reporting and backup withholding, unless theNon-U.S. Holder properly certifies under penalties of perjury as to itsnon-U.S. status (generally on IRS FormW-8BEN,W-8BEN-E,W-8ECI,W-8EXP orW-8IMY, as applicable) and certain other conditions are met or theNon-U.S. Holder otherwise establishes an exemption.

Backup withholding is not an additional tax. Rather, aNon-Corporate U.S. Holder orNon-U.S. Holder generally may obtain a credit for any amount withheld against its liability for U.S. federal income tax (and obtain a refund of any amounts withheld in excess of such liability) by accurately completing and timely filing a U.S. federal income tax return with the IRS.

S-22

NON-UNITED STATES TAX CONSIDERATIONS

The following discussion is based upon the opinion of Watson Farley & Williams LLP, 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 and is applicable only to persons who do not reside in, maintain offices in or engage in business, operations or transactions in the Republic of the Marshall Islands and are not citizens of the Republic of the Marshall Islands.

Because we and our subsidiaries do not, and we do not expect that we or any of our subsidiaries will, conduct business, transactions 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 holders of our common stock will not be subject to Marshall Islands taxation or withholding on dividends. In addition, holders of our common stock will not be subject to Marshall Islands stamp, capital gains or other taxes on the purchase, ownership or disposition of shares of common stock, and you will not be required by the Republic of the Marshall Islands to file a tax return relating to the shares of common stock.

It is the responsibility of each shareholder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, including the Marshall Islands, of its investment in us. Accordingly, each shareholder is urged to consult its tax counsel or other advisor with regard to those matters. Further, it is the responsibility of each shareholder to file all state, local andnon-U.S., as well as U.S. federal, tax returns which may be required of such shareholder.

S-23

PLAN OF DISTRIBUTION

We have entered into an equity distribution agreement with Citigroup Global Markets Inc., or the “Agent,” under which we may offer and sell shares of common stock having an aggregate offering price of up to $63,000,000 from time to time through the Agent, as our sales agent. We have filed the equity distribution agreement as an exhibit to a Report on Form6-K, which is incorporated by reference in this prospectus supplement. The sales, if any, of shares of our common stock made under the equity distribution agreement will be made by means of ordinary brokers’ transactions on the New York Stock Exchange at market prices, in block transactions, or as otherwise agreed upon by the Agent and us. As sales agent, the Agent will not engage in any transactions that stabilize the price of our common stock.

Under the terms of the equity distribution agreement, we also may sell shares of our common stock to the Agent as principal for its own account at a price agreed upon at the time of sale. If we sell shares of our common stock to the Agent as principal, we will enter into a separate agreement with the Agent, and we will describe this agreement in a separate prospectus supplement or pricing supplement.

We will designate the maximum amount of common stock to be sold through the Agent on a daily basis or otherwise as we and the Agent agree and the minimum price per share at which such common stock may be sold. Subject to the terms and conditions of the equity distribution agreement, the Agent will use its reasonable efforts to sell on our behalf all of the designated shares of common stock. We may instruct the Agent not to sell any common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or the Agent may suspend the offering of common stock at any time and from time to time by notifying the other party.

The Agent will provide to us written confirmation following the close of trading on the New York Stock Exchange each day on which common stock is sold under the equity distribution agreement. Each confirmation will include the number of shares sold on that day, the gross sales proceeds, the net proceeds to us (after regulatory transaction fees, if any, but before other expenses) and the compensation payable by us to the Agent. We will report at least quarterly the number of shares sold through the Agent under the equity distribution agreement, the net proceeds to us (before expenses) and the compensation paid by us to the Agent in connection with the sales of common stock.

We will pay the Agent a commission of up to 2% of the gross sales price per share sold through it as our agent under the equity distribution agreement. We have agreed to reimburse the Agent for certain of its expenses.

Settlement for sales of shares of our common stock will occur on the second business day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

If we or the Agent have reason to believe that our common stock is no longer an “actively-traded security” as defined under Rule 101(c)(l) of Regulation M under the U.S. Securities Exchange Act of 1934, as amended, that party will promptly notify the other and sales of common stock pursuant to the equity distribution agreement or any terms agreement will be suspended until in our collective judgment Rule 101(c)(1) or another exemptive provision has been satisfied.

The offering of shares of our common stock pursuant to the equity distribution agreement will terminate upon the earlier of (1) the sale of all common stock subject to the equity distribution agreement and (2) the termination of the equity distribution agreement by us or by the Agent.

In connection with the sale of the shares of our common stock on our behalf, the Agent may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the Agent may be

S-24

deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to the Agent against certain liabilities, including liabilities under the Securities Act.

Citigroup Global Markets Inc. and its affiliates have, from time to time, performed, and may in the future perform, various financial advisory and commercial and investment banking services for us and our affiliates, for which they have received and in the future will receive customary compensation and expense reimbursement. Citigroup Global Markets Inc. is acting as an initial purchaser in the Note Offering. Affiliates of Citigroup Global Markets Inc. are lenders under certain of our and our affiliates’ credit facilities, including the Margin Loan Agreement, dated December 21, 2012, as amended. To the extent we use proceeds from this offering to repay indebtedness under our credit facilities, affiliates of Citigroup Global Markets Inc. may receive a portion of the proceeds from this offering.

S-25

LEGAL MATTERS

Certain legal matters will be passed upon for us by Perkins Coie LLP, Portland, Oregon. The validity of the shares of our common stock offered hereby and certain other legal matters with respect to the laws of the Republic of the Marshall Islands will be passed upon for us by Watson Farley & Williams LLP. Baker Botts L.L.P., Washington, D.C., will pass upon certain legal matters in connection with the offering on behalf of the Agent.

FORWARD-LOOKING STATEMENTS

All statements, other than statements of historical fact, included in or incorporated by reference into this prospectus and any prospectus supplements are “forward-looking statements.” The Private Securities Litigation Reform Act of 1995, as amended, provides a “safe harbor” for forward-looking statements to encourage companies to provide prospective information about themselves so long as they identify these statements as forward-looking and provide meaningful cautionary statements identifying important factors that could cause actual results to differ from the projected results. In addition, we and our representatives may from time to time make other oral or written statements that are also forward-looking statements. Such statements include, in particular, statements about our plans, strategies, business prospects, changes and trends in our business, and the markets in which we operate. In some cases, you can identify the forward-looking statements by the use of words such as “may,” “will,” “could,” “should,” “would,” “expect,” “plan,” “anticipate,” “intend,” “forecast,” “believe,” “estimate,” “predict,” “propose,” “potential,” “continue” or the negative of these terms or other comparable terminology.

Forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events affecting us. Forward-looking statements are subject to risks, uncertainties and assumptions, including those risks discussed in “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” set forth in our most recent Annual Report on Form20-F, as amended, and other reports we file with the SEC and that are incorporated into this prospectus by reference. The risks, uncertainties and assumptions involve known and unknown risks and are inherently subject to significant uncertainties and contingencies, many of which are beyond our control. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

We undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict all of these factors. In addition, we cannot assess the effect of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement, and accordingly, you should not place undue reliance on forward-looking statements.

TEEKAY CORPORATION

We are a leading provider of international crude oil and gas marine transportation services and we also offer offshore oil production, storage and offloading services, primarily under long-term, fixed-rate contracts. Over the past decade, we have undergone a major transformation from being primarily an owner of ships in the cyclical spot tanker business to being a growth-oriented asset manager in the “Marine Midstream” sector. This transformation has included our expansion into the liquefied natural gas (orLNG) and liquefied petroleum gas (orLPG) shipping sectors through our publicly-listed subsidiary Teekay LNG Partners L.P. (NYSE: TGP) (orTeekay LNG), further growth of our operations in the offshore production, storage and transportation sector through our publicly-listed subsidiary Teekay Offshore Partners L.P. (NYSE: TOO) (orTeekay Offshore) and through our 100% ownership interest in Teekay Petrojarl AS, and the continuation of our conventional tanker business through our publicly-listed subsidiary Teekay Tankers Ltd. (NYSE: TNK) (orTeekay Tankers). Our organizational structure can be divided into (a) our controlling interests in our publicly-listed subsidiaries, Teekay Offshore, Teekay LNG and Teekay Tankers and (b) Teekay Corporation and its remaining subsidiaries.

Teekay Offshore includes our shuttle tanker operations, floating storage andoff-take (orFSO) units, one HiLoad DP unit, a majority of our floating production, storage and offloading (orFPSO) units, and offshore support which includes Units for Maintenance and Safety (orUMS), all of which primarily operate under long-term fixed-rate contracts, and long-distance towing and offshore installation vessels.

Teekay LNG includes all of our LNG and LPG carriers. LNG carriers are usually chartered to carry LNG pursuant to time-charter contracts, where a vessel is hired for a fixed period of time. LPG carriers are mainly chartered to carry LPG on time charters, on contracts of affreightment or spot voyage charters.

Teekay Tankers, including Teekay Tankers’ minority investment in Tanker Investments Ltd., includes a substantial majority of our conventional crude oil tankers and product carriers. Our conventional crude oil tankers and product tankers primarily operate in the spot-tanker market or are subject to time charters or contracts of affreightment that are priced on a spot-market basis or are short-term, fixed-rate contracts. We consider contracts that have an original term of less than one year in duration to be short-term. Certain of our conventional crude oil tankers and product tankers are on fixed-rate time-charter contracts with an initial duration of at least one year. Our conventional Aframax, Suezmax, and large and medium product tankers are among the vessels included in Teekay Tankers.

The Teekay organization was founded in 1973. We are a Republic of the Marshall Islands corporation and maintain our principal executive headquarters at 4^th floor, Belvedere Building, 69 Pitts Bay Road, Hamilton, HM 08, Bermuda. Our telephone number at such address is (441)298-2530. Our principal operating office is located at Suite 2000, Bentall 5, 550 Burrard Street, Vancouver, British Columbia, Canada, V6C 2K2. Our telephone number at such address is (604)683-3529. Our website address iswww.teekay.com. The information contained in our website is not part of this prospectus.

RISK FACTORS

An investment in our securities involves a high degree of risk. You should carefully consider the risks described below, in the sections entitled “Risk Factors” in any prospectus supplement and those set forth in documents incorporated by reference in this prospectus and any applicable prospectus supplement, including our most recent Annual Report on Form20-F, as amended, and if applicable, in our Reports on Form6-K filed with or furnished to the SEC, as well as other information in this prospectus and any prospectus supplement, before purchasing any of our securities. Each of the risks described in these sections and documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a loss of your investment. Additional risks and uncertainties known or not known to us or that we deem immaterial may also impair our business, financial condition, results of operations and prospects.

U.S. tax authorities could treat us as a “passive foreign investment company,” which could have adverse U.S. federal income tax consequences to U.S. shareholders.

A non-U.S. entity treated as a corporation for U.S. federal income tax purposes will be treated as a “passive foreign investment company” (orPFIC) for such purposes in any taxable year for which either (a) at least 75% of its gross income consists of “passive income,” or (b) at least 50% of the average value of the entity’s assets is attributable to assets that produce or are held for the production of “passive income.” For purposes of these tests, “passive income” includes dividends, interest, gains from the sale or exchange of investment property and rents and royalties other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business. By contrast, income derived from the performance of services does not constitute “passive income.”

There are legal uncertainties involved in determining whether the income derived from our time-chartering activities constitutes rental income or income derived from the performance of services, including the decision inTidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), which held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a foreign sales corporation provision of the Internal Revenue Code of 1986, as amended (or theCode). However, the Internal Revenue Service (orIRS) stated in an Action on Decision (AOD 2010-01) that it disagrees with, and will not acquiesce to, the way that the rental versus services framework was applied to the facts in theTidewaterdecision, and in its discussion stated that the time charters at issue inTidewaterwould be treated as producing services income for PFIC purposes. The IRS’s statement with respect toTidewatercannot be relied upon or otherwise cited as precedent by taxpayers. Consequently, in the absence of any binding legal authority specifically relating to the statutory provisions governing PFICs, there can be no assurance that the IRS or a court would not follow theTidewaterdecision in interpreting the PFIC provisions of the Code. Nevertheless, based on the current composition of our assets and operations (and those of our subsidiaries), we intend to take the position that we are not now and have never been a PFIC, and our counsel, Perkins Coie LLP, is of the opinion that it is more likely than not we are not a PFIC based on representations we have made to them regarding the composition of our assets, the source of our income and the nature of our activities and operations. No assurance can be given, however, that the opinion of Perkins Coie LLP would be sustained by a court if contested by the IRS, or that we would not constitute a PFIC for any future taxable year if there were to be changes in our assets, income or operations.

If the IRS were to determine that we are or have been a PFIC for any taxable year during which a U.S. Holder (as defined below under “Material United States Federal Income Tax Considerations”) held stock, such U.S. Holder would face adverse U.S. federal income tax consequences. For a more comprehensive discussion regarding our status as a PFIC and the tax consequences to U.S. Holders if we are treated as a PFIC, please read “Material United States Federal Income Tax Considerations—United States Federal Income Taxation of U.S. Holders—Consequences of Possible PFIC Classification.”

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges for the periods presented. We have no outstanding preferred stock, therefore no ratio of combined fixed charges and preference dividends is presented.

	Nine Months Ended September 30, 2017(2)		Year Ended December 31,
			2016(2)		2015		2014(2)		2013(2)		2012(2)
Ratio of earnings to fixed charges(1)		—		—		2.2x		—		—		—

(1) This data is unaudited for all periods presented. For purposes of computing our ratio of earnings to fixed charges on a consolidated basis, earnings is the result of adding(a) pre-tax income from continuing operations before adjustment for minority interests in consolidated subsidiaries or income or loss from equity investees, (b) fixed charges, (c) amortization of capitalized interest, and (d) distributed income of equity investees, and subtracting (a) interest capitalized and (b) preference security distributions of subsidiaries. Fixed charges represent (i) interest expensed and capitalized, (ii) amortized premiums, discounts and capitalized expenses related to indebtedness, (iii) interest within time-charter hire expense and (iv) preference security dividend requirements of consolidated subsidiaries.

(2) For the nine months ended September 30, 2017 and the years ended December 31, 2016, 2014, 2013 and 2012, the ratio of earnings to fixed charges was less than 1.0x. The amount of the deficiency for these periods was $437.2 million, $19.2 million, $19.2 million, $99.5 million and $418.9 million, respectively. These amounts were impacted by significant non-cash charges, including asset impairments of $45.8 million, $167.6 million, and $432.2 million for the years ended December 31, 2016, 2013, and 2012, respectively, losses (gains) on sale of vessels amounted to $66.5 million, and ($8.8) million for the years ended December 31, 2016, and 2014, respectively, as well as unrealized losses (gains) on derivative instruments, excluding cross currency swaps, of ($69.4) million, $100.5 million, ($178.9) million, and ($30.3) million for the years ended December 31, 2016, 2014, 2013, and 2012, respectively. In addition, the amount for the nine months ended September 30, 2017, was affected by asset impairments of $245.2 million, loss on deconsolidation of Teekay Offshore of $103.2 million and a $25.1 million loss on sale of vessels.

CAPITALIZATION

Our capitalization and indebtedness will be set forth in a prospectus supplement to this prospectus or in a Report on Form6-K subsequently furnished to the SEC and specifically incorporated herein by reference.

DESCRIPTION OF CAPITAL STOCK

General

We may issue common stock or preferred stock, in one or more distinct series, from time to time. This section summarizes the material terms of our common stock and material terms that would be common to all series of our preferred stock. The following description of our common stock, preferred stock and provisions of our Amended and Restated Articles of Incorporation, as amended (orArticles) and our Amended and Restated Bylaws (orBylaws), are summaries and are qualified by reference to our Articles and our Bylaws, copies of which have been filed as exhibits to our Annual Report on Form20-F, as amended, for the year ended December 31, 2016, which is incorporated by reference herein.

Our authorized capital stock consists of 725 million shares of common stock, with a par value of $0.001 per share, and 25 million shares of preferred stock, with a par value of $1 per share. As of December 21, 2017, there were 88,433,041 shares of our common stock outstanding and no shares of preferred stock outstanding.

Exchange Listing.

Shares of our common stock are listed on the New York Stock Exchange, where they trade under the symbol “TK.”

Transfer Agent and Registrar.

Computershare Inc. serves as registrar and transfer agent for our common stock.

Common Stock

Each outstanding share of our common stock entitles the holder to one vote on all matters submitted to a vote of shareholders. Subject to preferences that may be applicable to any outstanding shares of our preferred stock, holders of common stock are entitled to receive ratably any dividends declared from time to time by our Board of Directors out of funds legally available therefor. Holders of our common stock generally do not have conversion, redemption or preemptive rights to subscribe for any of our securities. All outstanding shares of common stock are fully paid and nonassessable. The rights, preferences and privileges of holders of our common stock are subject to the rights of the holders of any shares of preferred stock that we may issue.

Preferred Stock

Our Board of Directors may from time to time, and without further action by our shareholders, direct the issuance of shares of preferred stock in one or more series and may, at the time of issuance, determine the rights, preference and limitations of each such series. Satisfaction of any dividend preferences of outstanding shares of preferred stock would reduce the amount of funds available for the payment of dividends on shares of common stock. Holders of shares of our preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution orwinding-up of Teekay Corporation before any payment is made to the holders of shares of our common stock. The voting, dividend, liquidation, redemption, conversion or other rights of any preferred stock we may issue could adversely affect the voting power and other rights of the holders of our common stock and may have the effect of decreasing the market price of our common stock. Under certain circumstances, the issuance of shares of our preferred stock may render more difficult or tend to discourage a merger, tender offer, proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management.

Anti-Takeover Provisions

Preferred Stock Authorization.

As noted above, our Board of Directors, without shareholder approval, has the authority under our Articles to issue preferred stock with rights superior to the rights of the holders of common stock. As a result, preferred

8

stock could be issued quickly and easily, could adversely affect the rights of holders of common stock and could be issued with terms calculated or which have a tendency to delay or prevent a change of control of Teekay Corporation or make removal of management more difficult.

Shareholder Rights Plan.

We have an amended and restated shareholders rights agreement pursuant to which holders of our common stock have been granted one purchase right on each outstanding share of common stock. Each purchase right, when exercisable, initially entitles its registered holder to purchase from us one share of our common stock at a price of $200 per share, subject to certain anti-dilution adjustments. The purchase rights are not currently exercisable and will become exercisable only upon the earlier of:

• Ten days following a public announcement that a person became an “acquiring person,” which refers to a person who either (a) did not beneficially own 15% or more of our outstanding common stock on July 2, 2010 (the effective date of the amended and restated shareholder rights plan), and subsequently acquires beneficial ownership of 20% or more of our outstanding common stock, or (b) did beneficially own 15% or more of our outstanding common stock on July 2, 2010, and subsequently acquires beneficial ownership of an additional 5% or more of our outstanding common stock; or

• Ten business days (or such later date as may be determined by action of the Board of Directors prior to such time as any person or group of affiliated persons becomes an acquiring person) following the commencement of, or announcement of an intention to make, a tender offer or exchange offer the consummation of which would result in a person or group becoming an acquiring person.

Unless otherwise approved by our Board of Directors, if a person becomes an acquiring person, the purchase rights held at any time by the acquiring person and its affiliates will become null and void and nontransferable, and the remaining purchase rights will entitle each other right holder to purchase, for the purchase price, the number of shares of our common stock which at the time of the transaction would have a market value equal to twice the purchase price. Additionally, at any time prior to an acquiring person’s becoming the holder of 50% or more of our outstanding shares of common stock, our Board of Directors may exchange the purchase rights (other than the purchase rights owned by the acquiring person and its affiliates), at an exchange ratio of one share of our common stock per purchase right.

After a person becomes an acquiring person, each of the following events would entitle each holder of a purchase right (other than the acquiring person and its affiliates) to purchase, for the purchase price, that number of shares of common stock of another corporation which at the time of the event would have a market value equal to twice the purchase price:

• the acquisition of us in a merger by such other corporation;

• a business combination between us and such other corporation; or

• the sale, lease, exchange or transfer of 50% or more of our assets or assets accounting for 50% or more of our net income or revenues, in one or more transactions.

At any time prior to the earlier of a triggering offer or any person becoming an acquiring person, our Board of Directors may redeem the purchase rights in whole, but not in part, at a price of $0.0001 per purchase right. In addition, the Board of Directors may also waive, within a specified period, the effect of such triggering event or a person being an acquiring person.

The purchase rights have certain anti-takeover effects and will cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our Board of Directors. The purchase rights will not interfere with any merger or other business combination approved by our Board of Directors, since the Board of Directors may, at its option, authorize Teekay Corporation to redeem all of the then-outstanding purchase rights

9

or waive the application of the shareholder rights plan in connection with a specific transaction. The shareholder rights plan and the rights expire in July 2020. The description and terms of the purchase rights are set forth in our Amended and Restated Rights Agreement that is filed as an exhibit to the Registration Statement on Form8-A/A filed on July 2, 2010, which is incorporated by reference into this prospectus.

Shareholder Meetings, Quorum, Voting and Consents.

Our Bylaws establish advance notice procedures with respect to business brought before an annual meeting by a shareholder and the nomination of candidates for election as directors, other than nominations made by or at the direction of our Board of Directors. Under our Bylaws, special meetings of the shareholders may be called only by our Board of Directors. No business other than that stated in the notice of meeting may be transacted at any special meeting. Our Articles provide that a majority of the shares entitled to vote on any matter shall constitute a quorum at a meeting of shareholders, unless the matter has been submitted to the shareholders at any meeting and recommended by a majority of our Continuing Directors (as defined in our Articles), in which caseone-third of the shares entitled to vote on the matter shall constitute a quorum. In addition, under Republic of the Marshall Islands law, shareholder actions taken without a shareholder meeting or a vote must be taken by unanimous written consent of the shareholders entitled to vote with respect to the subject matter thereof. These provisions may have the effect of delaying or preventing consideration of certain shareholder proposals until the next annual meeting, if at all, unless a special meeting is called by our Board of Directors.

Election of Directors.

Our Bylaws provide for a “staggered board,” with our Board of Directors divided into three classes, as nearly equal in number as possible, and the directors in each class serving three-year terms and one class being elected each year by our shareholders. Vacancies on the Board of Directors are filled by our Board of Directors. Because this system of electing directors and filling vacancies generally makes it more difficult for shareholders to replace a majority of the Board of Directors, it may tend to discourage a third party from making a tender offer or otherwise attempting to gain control of us.

Other Matters

Sales of Assets, Mergers and Dissolution.

Under the Marshall Islands Business Corporations Act, the sale of all or substantially all of Teekay Corporation’s assets not made in the usual or regular course of Teekay Corporation’s business or thenon-judicial dissolution and liquidation of Teekay Corporation are required to be approved by the holders oftwo-thirds of the outstanding shares of our capital stock entitled to vote on such matter or by a unanimous written consent of all holders of capital stock entitled to vote on the matter. In addition, the holders ofone-half of the outstanding shares of capital stock entitled to vote may institute judicial dissolution proceedings in specified circumstances in accordance with the Marshall Islands Business Corporations Act. In the event of the dissolution of Teekay Corporation, the holders of our common stock will be entitled to share pro rata in our net assets available for distribution to them, after payment to all creditors and the liquidation preferences of any of our outstanding preferred stock.

Under the Marshall Islands Business Corporations Act, a merger or consolidation involving Teekay Corporation (other than with subsidiaries at least 90% of whose shares are owned by Teekay Corporation) is required to be approved by the holders of a majority of the outstanding shares of our capital stock entitled to vote on the matter.

A class of shares may be entitled to vote separately as a class on various corporate activities. The vote for such class will be determined by the Marshall Islands Business Corporations Act and, if applicable, our articles of incorporation and bylaws.

10

Dissenters’ Rights of Appraisal and Payment.

Under the Marshall Islands Business Corporations Act, our shareholders have the right to dissent from various corporate actions, including certain mergers or sales 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. The right of a dissenting shareholder to receive payment of the fair value of such shareholder’s shares shall not be available for the shares of any class or series of stock, which shares, at the record date fixed to determine the shareholders entitled to receive notice of and to vote at the meeting of shareholders to act upon the agreement of merger or consolidation, were either (i) listed on a securities exchange or admitted for trading on an interdealer quotation system or (ii) held of record by more than 2,000 holders. 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. A condition for such payment is that the dissenting shareholders follow the procedures set forth in the Marshall Islands Business Corporations Act. In the event that we fail to agree with any dissenting shareholder on a price for the shares, such procedures involve, among other things, the institution of court proceedings in either the Republic of the Marshall Islands or the country where our shares are primarily traded, which is the United States. The value of the shares of a dissenting shareholder is fixed by the court after reference, if the court so elects, to the recommendations of a court-appointed appraiser.

Amendment of Articles of Incorporation.

Under the Marshall Islands Business Corporations Act, amendments to the articles of incorporation of a Republic of the Marshall Islands corporation generally may be authorized by vote of the holders of a majority of all outstanding shares entitled to vote. The approval of the holders of a majority of the outstanding shares of an adversely affected class or series of stock is also required for certain amendments.

Limitations on Ownership and Dividends.

Neither Republic of the Marshall Islands law nor our Articles or Bylaws limit the right to own our securities, including the rights ofnon-resident or foreign shareholders to hold or exercise voting rights on the securities. Certain of our debt facilities, and Republic of the Marshall Islands law, impose limitations on our ability to pay dividends.

11

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities (any of which may be senior or subordinated and convertible or not convertible) from time to time in one or more series, under an indenture to be dated as of a date on or prior to our initial issuance of the debt securities. The following description of debt securities sets forth the material terms and provisions of the debt securities to which any prospectus supplement may relate. Our senior debt securities would be issued under a senior indenture, and our subordinated debt securities would be issued under a subordinated indenture. The senior or subordinated indenture for debt securities and any convertible debt securities, forms of which are included as exhibits to the registration statement of which this prospectus is a part, will be executed at the time we issue applicable debt securities. Any supplemental indentures will be filed with the SEC on a Form6-K or by a post-effective amendment to the registration statement of which this prospectus is a part.

All of the indentures are sometimes referred to in this prospectus collectively as the “Indentures” and each, individually, as an “Indenture”. The particular terms of the debt securities offered by any prospectus supplement, and the extent to which the general provisions described below may apply to the offered debt securities, will be described in the applicable prospectus supplement. The Indentures will be qualified under the Trust Indenture Act of 1939, as amended (or the Trust Indenture Act). The terms of the debt securities will include those stated in the Indentures and those made part of the Indentures by reference to the Trust Indenture Act.

Our statements below relating to the debt securities and the Indentures are summaries of their anticipated provisions, are not complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the applicable Indenture and any applicable United States federal income tax considerations as well as any applicable modifications of or additions to the general terms described below in the applicable prospectus supplement or supplemental indenture.

General

The provisions of the Indentures do not limit the aggregate principal amount of debt securities which may be issued thereunder. Unless otherwise provided in a prospectus supplement and an applicable supplemental indenture, any senior debt securities will be our direct, unsecured and unsubordinated general obligations and will have the same rank in liquidation as all of our other unsecured and unsubordinated debt, and the subordinated debt securities will be our unsecured obligations, subordinated in right of payment to the prior payment in full of all of our senior indebtedness with respect to such series, as described in the applicable prospectus supplement. Any debt securities may be convertible into common stock.

We may issue the debt securities as original issue discount securities, which will be offered and sold at a substantial discount below their stated principal amount. The prospectus supplement relating to any original issue discount securities will describe United States federal income tax consequences and other special considerations applicable to them. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

In addition, the specific financial, legal and other terms particular to a series of debt securities will be described in the prospectus supplement and any pricing supplement relating to the series. The prospectus supplement relating to a series of debt securities will describe the following terms of the series:

• the title of the series of the offered debt securities;

• the price or prices at which the offered debt securities will be issued;

• any limit on the aggregate principal amount of the offered debt securities;

• the date or dates on which the principal of the offered debt securities will be payable;

12

• the rate or rates (which may be fixed or variable) per year at which the offered debt securities will bear interest, if any, or the method of determining the rate or rates and the date or dates from which interest, if any, will accrue;

• if the amount of principal, premium or interest with respect to the offered debt securities of the series may be determined with reference to an index or pursuant to a formula, the manner in which these amounts will be determined;

• the date or dates on which interest, if any, on the offered debt securities will be payable and the regular record dates for the payment thereof;

• the place or places, if any, in addition to or instead of the corporate trust office of the trustee, where the principal, premium and interest with respect to the offered debt securities will be payable;

• the period or periods, if any, within which, the price or prices of which, and the terms and conditions upon which the offered debt securities may be redeemed, in whole or in part, pursuant to optional redemption provisions;

• the terms on which we would be required to redeem or purchase the offered debt securities pursuant to any sinking fund or similar provision, and the period or periods within which, the price or prices at which and the terms and conditions on which the offered debt securities will be so redeemed and purchased in whole or in part;

• the denominations in which the offered debt securities will be issued;

• the form of the offered debt securities and whether the offered debt securities are to be issued in whole or in part in the form of one or more global securities and, if so, the identity of the depositary for the global security or securities;

• the portion of the principal amount of the offered debt securities that is payable on the declaration of acceleration of the maturity, if other than their principal amount;

• if other than U.S. dollars, the currency or currencies in which the offered debt securities will be denominated and payable, and the holders’ rights, if any, to elect payment in a foreign currency or a foreign currency unit other than that in which the offered debt securities are otherwise payable;

• whether the offered debt securities will be issued with guarantees and, if so, the terms of any guarantee of the payment of principal and interest with respect to the offered debt securities;

• any addition to, or modification or deletion of, any event of default or any covenant specified in the applicable Indenture;

• the consequences of any failure to pay principal, interest, or, if applicable, any sinking or amortization installment;

• whether the offered debt securities will be convertible or exchangeable into common stock, and if so, the terms and conditions upon which the offered debt securities will be convertible or exchangeable;

• whether the offered debt securities will be senior or subordinated debt securities, and if subordinated the aggregate amount of outstanding indebtedness that is senior to the subordinated debt and any limitations on the issuance of additional senior indebtedness, if any;

• whether the applicable Indenture will include provisions restricting the declaration of distributions or requiring the creation or maintenance of any reserves or of any ratio of assets;

• any trustees, authenticating or paying agents, transfer agents or registrars or other agents with respect to the offered debt securities; and

• any other specific terms of the offered debt securities.

13

Consolidation, Merger and Sale of Assets

The terms of the Indentures in the forms initially filed as exhibits to the registration statement of which this prospectus is a part provide that we may not consolidate with or merge with or into, any other person or sell, assign, convey, transfer, lease our properties and assets as an entirety or substantially as an entirety to any person, unless:

• the successor person is a corporation organized and existing under the laws of the Republic of the Marshall Islands, the United States, any state of the United States or the District of Columbia and expressly assumes by supplemental indenture all of our obligations under the debt securities and the applicable Indenture;

• immediately after giving effect to the transaction, no default or event of default shall have occurred and be continuing; and

• other conditions specified in the applicable Indenture are met.

Upon any consolidation, merger, sale, assignment, conveyance, transfer or lease of the properties and assets of the Company in accordance with the foregoing provisions, the successor person formed by such consolidation or into which we are merged or to which such sale, assignment, conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under the applicable Indenture; and thereafter, except in the case of a lease, the Company shall be released from all obligations and covenants under the applicable Indenture and the debt securities.

Events of Default

The terms of the Indentures in the forms initially filed as exhibits to the registration statement of which this prospectus is a part provide that the debt securities are subject to the following events of default:

(1) failure to pay principal of or any premium when due;

(2) failure to pay any interest when due, continued for 30 days;

(3) failure to perform any of our other covenants in the applicable Indenture, continued for 60 days after written notice has been given by the trustee, or the holders of at least 25% in principal amount of the outstanding debt securities, as provided in the applicable Indenture;

(4) failure to deposit any sinking fund payment when due;

(5) certain events of bankruptcy, insolvency or reorganization affecting us.

If an event of default, other than an event of default described in clause (5) above, occurs and is continuing, either the trustee under the applicable Indenture or the holders of at least 25% in aggregate principal amount of the outstanding debt securities may declare the principal amount of the debt securities to be due and payable immediately. If an event of default described in clause (5) above occurs, the principal amount of the debt securities and accrued and unpaid interest, if any, will automatically become immediately due and payable.

After any such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the debt securities may, under certain circumstances, rescind and annul such acceleration if all events of default, other than thenon-payment of accelerated principal and any premium, interest or any additional amounts, or “Additional Amounts”, which are required under the applicable Indenture or the debt securities to be paid by the Company, in each case which have become due as a result of such acceleration, have been cured or waived.

The trustee will not be obligated to exercise any of its rights or powers at the request of the holders unless the holders have offered to the trustee indemnity or security reasonably satisfactory to it against any loss, liability

14

or expense. Subject to the applicable Indenture, applicable law and the trustee’s indemnification, the holders of a majority in aggregate principal amount of the outstanding debt securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities. In the event an event of default has occurred and is continuing, the trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs. The trustee, however, may refuse to follow any direction that conflicts with law or the applicable Indenture or that the trustee determines is unduly prejudicial to the rights of any other holder.

No holder will have any right to institute any proceeding under the applicable Indenture, or for the appointment of a receiver or a trustee, or for any other remedy under the applicable Indenture unless:

• the holder has previously given the trustee written notice of a continuing event of default;

• the holders of not less than 25% in aggregate principal amount of the debt securities then outstanding have made a written request and have offered indemnity reasonably satisfactory to the trustee to institute such proceeding as trustee;

• such holder has offered to the trustee such indemnity as is reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; and

• the trustee has failed to institute such proceeding within 60 days after such notice, request and offer and has not received from the holders of a majority in aggregate principal amount of the debt securities then outstanding a direction inconsistent with such request within 60 days after such notice, request and offer.

However, the above limitations do not apply to a suit instituted by a holder for the enforcement of payment of the principal of, interest on and any Additional Amounts with respect any debt security on or after the applicable due date in accordance with the applicable Indenture.

Generally, the holders of not less than a majority of the aggregate principal amount of outstanding debt securities may waive any default or event of default unless:

• we fail to pay the principal of, any interest on or any Additional Amounts with respect to any debt security when due; or

• we fail to comply with any of the provisions of the applicable Indenture that would require the consent of the holder of each outstanding debt security affected.

The Indentures provide that within 90 days after the trustee receives written notice of a default, the trustee shall transmit by mail to all holders, notice of such default hereunder, unless such default shall have been cured or waived. Except in the case of a default in the payment of principal of or interest on any note, the trustee may withhold notice if and so long as the trustee in good faith determines that withholding notice is in the best interest of the holders. In addition, we are required to deliver to the trustee (i) within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any default that occurred during the previous year and whether we, to the officers’ knowledge, are in default in the performance or observance of any of the terms, provisions and conditions of the applicable Indenture and (ii) within 30 days after the occurrence thereof, written notice of any events that would constitute defaults, their status and what action we are taking or propose to take in respect thereof.

Each holder shall have the right to receive payment or delivery, as the case may be, of:

• the principal of;

• any premium and accrued and unpaid interest, if any, on; and

• Additional Amounts, if any, on

15

its debt securities, on or after the respective due dates expressed or provided for in the applicable Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, and such right to receive such payment or delivery, as the case may be, on or after such respective dates shall not be impaired or affected without the consent of such holder.

Modification and Waiver

We and the trustee may amend or supplement the Indentures with respect to the debt securities with the consent of the holders of a majority in aggregate principal amount of the outstanding debt securities. In addition, the holders of a majority in aggregate principal amount of the outstanding debt securities may waive our compliance in any instance with any provision of the applicable Indenture without notice to the other holders of debt securities. However, no amendment, supplement or waiver may be made without the consent of each holder of outstanding debt securities affected thereby if such amendment, supplement or waiver would:

• change the stated maturity of the principal of, or any premium or installment of interest on or any Additional Amounts with respect to the debt securities;

• reduce the principal amount of or interest on the debt securities or any Additional Amounts with respect thereto;

• change the currency of payment of principal of, any premium or interest on or any Additional Amounts with respect to the debt securities or change any debt security’s place of payment;

• reduce the percentage in principal amount of the outstanding debt securities of any series, the consent of whose holders is required for any such supplemental indenture or waiver, provided for in the applicable Indenture, or reduce the requirements for quorum or voting;

• impair the right of any holder to receive payment of principal of and interest on such holder’s debt securities on or after the due dates therefor or to institute suit for the enforcement of any payment on, or with respect to, the debt securities;

• impair the right to convert or exchange any debt security into or for securities of the Company or other securities, cash or property in accordance with the debt security’s terms;

• change the ranking of the debt securities;

• change our obligation to pay Additional Amounts on any debt security; or

• modify provisions with respect to modification, amendment or waiver (including waiver of events of default), except to increase the percentage required for modification, amendment or waiver or to provide for consent of each affected holder of the debt securities.

We and the trustee may amend or supplement the Indentures or the debt securities without notice to, or the consent of, the holders of the debt securities to, among other things:

• cure any ambiguity, omission, defect or inconsistency that does not adversely affect the rights of any holder of the debt securities in any material respect;

• provide for the assumption by a successor corporation of our obligations under an Indenture;

• secure the debt securities;

• add to our covenants for the benefit of the holders or surrender any right or power conferred upon us; or

• make any change that does not adversely affect the rights of any holder.

The consent of the holders is not necessary under the Indentures to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After

16

an amendment under an Indenture becomes effective, we are required to mail to the holders a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment.

Satisfaction and Discharge

We may satisfy and discharge our obligations under the Indentures by delivering to the trustee for cancellation all outstanding debt securities or depositing with the trustee or delivering to the holders, as applicable, after all outstanding debt securities have become due and payable, or will become due and payable at their stated maturity within one year, cash sufficient to pay and discharge the entire indebtedness all of the outstanding debt securities and all other sums payable under the applicable Indenture by us. Such discharge is subject to terms contained in the applicable Indenture.

Defeasance

We may terminate at any time all our obligations with respect to the debt securities and the Indentures, which we refer to as “legal defeasance,” except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the debt securities, to replace mutilated, destroyed, lost or stolen debt securities and to maintain a registrar and paying agent in respect of the debt securities. We may also terminate at any time certain of our covenants with respect to the debt securities, which we refer to as “covenant defeasance.” We may exercise the legal defeasance option notwithstanding our prior exercise of the covenant defeasance option.

If we exercise our legal defeasance option with respect to the debt securities, payment of the debt securities may not be accelerated because of an event of default with respect thereto. If we exercise the covenant defeasance option with respect to the debt securities, payment of the debt securities may not be accelerated because of an event of default specified in clause (3) in “—Events of Default” above.

The legal defeasance option or the covenant defeasance option with respect to the debt securities may be exercised only if:

(1) we irrevocably deposit in trust with the trustee cash or U.S. government obligations or a combination thereof for the payment of principal of (and premium, if any) and interest and Additional Amounts, if any, on the debt securities to maturity,

(2) such legal defeasance or covenant defeasance does not constitute a default under the applicable Indenture or any other material agreement or instrument binding us,

(3) no default or event of default has occurred and is continuing on the date of such deposit and, with respect to legal defeasance only, at any time during the period ending on the 123rd day after the date of such deposit (other than, if applicable, a default or event of default with respect to the debt securities resulting from the borrowing of funds to be applied to such deposits),

(4) in the case of the legal defeasance option, we deliver to the trustee an opinion of counsel stating that we have received from the IRS, a letter ruling, or there has been published by the IRS a Revenue Ruling, or since the date of the applicable Indenture, there has been a change in the applicable U.S. Federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the holders of the debt securities will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such legal defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred,

(5) in the case of the covenant defeasance option, we deliver to the trustee an opinion of counsel to the effect that the holders of the debt securities will not recognize income, gain or loss for U.S. Federal

17

income tax purposes as a result of such covenant defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred,

(6) we deliver to the trustee an opinion of counsel to the effect that, after the 123rd day after the date of deposit, all money and U.S. government obligations (or other property as may be provided pursuant to the terms of the applicable Indenture) (including the proceeds thereof) deposited or caused to be deposited with the trustee (or other qualifying trustee) to be held in trust will not be subject to any case or proceeding (whether voluntary or involuntary) in respect of the Company under any U.S. federal or state bankruptcy, insolvency, reorganization or other similar law, or any decree or order for relief in respect of the Company issued in connection therewith, and

(7) we deliver to the trustee an officer’s certificate and an opinion of counsel, each stating that all conditions precedent to the legal defeasance and covenant defeasance have been complied with as required by the applicable Indenture.

Transfer and Exchange

We will maintain an office in New York City where the debt securities may be presented for registration of transfer or exchange. This office will initially be an office or agency of the trustee. No service charge will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of debt securities, but any tax or similar governmental charge required by law or permitted by the applicable Indenture because a holder requests any shares to be issued in a name other than such holder’s name will be paid by such holder. We are not required to transfer or exchange any note surrendered for purchase except for any portion of that note not being purchased.

We reserve the right to:

• vary or terminate the appointment of the security registrar or paying agent;

• appoint additional paying agents; or

• approve any change in the office through which any security registrar or any paying agent acts.

Payment and Paying Agents

Payments in respect of the principal and interest on global notes registered in the name of The Depository Trust Company (or DTC), or its nominee will be payable to DTC or its nominee, as the case may be, in its capacity as the registered holder under the applicable Indenture. In the case of certificated debt securities, payments will be made in U.S. dollars at the office of the trustee or, at our option, by check mailed to the holder’s registered address. We will make any required interest payments to the person in whose name each note is registered at the close of business on the record date for the interest payment.

We may at any time designate a paying agent or additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts.

Subject to the requirements of any applicable abandoned property laws, the trustee and paying agent shall pay to us upon written request any money held by them for payments on the debt securities that remain unclaimed for two years after the date upon which that payment has become due. After payment to us, holders entitled to the money must look to us for payment. In that case, all liability of the trustee or paying agent with respect to that money will cease.

Governing Law

The Indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York without regard to conflicts of laws.

18

Concerning the Trustee

We will enter into the Indentures with a trustee identified in the relevant prospectus supplement that is also qualified to act under the Trust Indenture Act and with any other trustee chosen by us and appointed in a supplemental indenture for a particular series of debt securities. We may maintain a banking relationship in the ordinary course of business with our trustee and one or more of its affiliates.

The trustee, in its individual and any other capacity, may make loans to, accept deposits from, and perform services for us as if it were not the trustee; however, if it acquires any conflicting interest, it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of certain material U.S. federal income tax considerations that may be relevant to prospective shareholders and, unless otherwise noted in the following discussion, is the opinion of Perkins Coie LLP, 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 the provisions of the Internal Revenue Code of 1986, as amended (or theCode), legislative history, applicable U.S. Treasury Regulations (orTreasury Regulations), judicial authority and administrative interpretations, all as in effect on the date of this prospectus, and which are subject to change, possibly with retroactive effect, or are subject to different interpretations. Changes in these authorities may cause the tax consequences to vary substantially from the consequences described below.

This discussion is limited to shareholders who hold their common stock as a capital asset for tax purposes. This discussion does not address all tax considerations that may be important to a particular shareholder in light of the shareholder’s circumstances, or to certain categories of shareholders that may be subject to special tax rules, such as:

• dealers in securities or currencies;

• traders in securities that have elected themark-to-market method of accounting for their securities;

• persons whose functional currency is not the U.S. dollar;

• persons holding our common stock as part of a hedge, straddle, conversion or other “synthetic security” or integrated transaction;

• certain U.S. expatriates;

• financial institutions;

• insurance companies;

• persons subject to the alternative minimum tax;

• persons that actually or under applicable constructive ownership rules own 10% or more of our common stock; and

• entities that aretax-exempt for U.S. federal income tax purposes.

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. Partners in partnerships holding our common stock should consult their tax advisors to determine the appropriate tax treatment of the partnership’s ownership of our common stock.

No ruling has been or will be requested from the Internal Revenue Service (orIRS) regarding any matter affecting us or our shareholders. Instead, we will rely on the opinion of Perkins Coie LLP. Unlike a ruling, an opinion of counsel represents only that counsel’s legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made herein may not be sustained by a court if contested by the IRS.

This discussion does not address any U.S. estate tax considerations or tax considerations arising under the laws of any state, local ornon-U.S. jurisdiction. Each shareholder is urged to consult its tax advisor regarding the U.S. federal, state, local and other tax consequences of the ownership or disposition of our common stock.

Any material tax considerations relevant to an investment decision by a U.S. Holder or Non–U.S. Holder, each as defined below, with respect to securities registered under this registration statement other than the common stock, will be described in a prospectus supplement issued in connection with the offering of such securities.

20

United States Federal Income Taxation of U.S. Holders

As used herein, the term U.S. Holder means a beneficial owner of our common stock that is, for U.S. federal income tax purposes: (a) a U.S. citizen or U.S. resident alien (or aU.S. Individual Holder), (b) a corporation or other entity taxable as a corporation that was created or organized under the laws of the United States, any state thereof or the District of Columbia, (c) an estate whose income is subject to U.S. federal income taxation regardless of its source, or (d) a trust that either is subject to the supervision of a court within the United States and has one or more U.S. persons with authority to control all of its substantial decisions or has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.

Distributions

Subject to the discussion of passive foreign investment companies (orPFICs) below, any distributions made by us with respect to our common stock to a U.S. Holder generally will 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 current and accumulated 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 our common stock and thereafter as capital gain, which will be either long term or short term capital gain depending upon whether the U.S. Holder has held the common stock for more than one year. U.S. Holders that are corporations for U.S. federal income tax purposes generally will not be entitled to claim a dividends received deduction with respect to any distributions they receive from us. For purposes of computing allowable foreign tax credits for U.S. federal income tax purposes, dividends received with respect to our common stock will be treated as foreign source income and generally will be treated as “passive category income.”

Subject to holding period requirements and certain other limitations, dividends received with respect to our common stock by a U.S. Holder who is an individual, trust or estate (or aNon- Corporate U.S. Holder) will be treated as “qualified dividend income” that is taxable to suchNon-Corporate U.S. Holder at preferential capital gain tax rates provided that we are not classified as a PFIC for the taxable year during which the dividend is paid or the immediately preceding taxable year (we intend to take the position that we are not now and have never been classified as a PFIC, as discussed below). Any dividends received with respect to our common stock not eligible for these preferential rates will be taxed as ordinary income to aNon-Corporate U.S. Holder.

Special rules may apply to any “extraordinary dividend” paid by us. Generally, an extraordinary dividend is a dividend with respect to a share of common stock if the amount of the dividend is equal to or in excess of 10% of a common shareholder’s adjusted tax basis (or fair market value in certain circumstances) in such common stock. In addition, extraordinary dividends include dividends received within a one year period that, in the aggregate, equal or exceed 20% of a shareholder’s adjusted tax basis (or fair market value in certain circumstances). If we pay an “extraordinary dividend” on our common stock that is treated as “qualified dividend income,” then any loss recognized by aNon-Corporate U.S. Holder from the sale or exchange of such common stock will be treated as long–term capital loss to the extent of the amount of such dividend.

CertainNon-Corporate U.S. Holders currently are subject to a 3.8% tax on certain investment income, including dividends.Non-Corporate U.S. Holders should consult their tax advisors regarding the effect, if any, of this tax on their ownership of our common stock.

Sale, Exchange or Other Disposition of Common Stock

Subject to the discussion of PFICs below, a U.S. Holder generally will recognize capital gain or loss upon a sale, exchange or other disposition of our common stock 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 stock. Subject to the discussion of extraordinary dividends above, such gain or loss generally will be

21

treated as (a) 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, or short term capital gain or loss otherwise and (b) U.S. source gain or loss, as applicable, for foreign tax credit purposes.Non-Corporate U.S. Holders may be eligible for preferential rates of U.S. federal income tax in respect of long-term capital gains. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations.

CertainNon-Corporate U.S. Holders currently are subject to a 3.8% tax on certain investment income, including capital gains from the sale or other disposition of stock.Non-Corporate U.S. Holders should consult their tax advisors regarding the effect, if any, of this tax on their disposition of our common stock.

Consequences of Possible PFIC Classification

A non–U.S. entity treated as a corporation for U.S. federal income tax purposes will be treated as a PFIC in any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to a “look through” rule, either: (a) at least 75% of its gross income is “passive” income; or (b) at least 50% of the average value of its assets is attributable to assets that produce or are held for the production of passive income. For purposes of these tests, “passive income” includes dividends, interest, gains from the sale or exchange of investment property and rents and royalties (other than rents and royalties that are received from unrelated parties in connection with the active conduct of a trade or business). By contrast, income derived from the performance of services does not constitute “passive income.”

There are legal uncertainties involved in determining whether the income derived from our time-chartering activities constitutes rental income or income derived from the performance of services, including legal uncertainties arising from the decision inTidewater Inc. v. United States, 565 F.3d 299 (5th Cir. 2009), which held that income derived from certain time-chartering activities should be treated as rental income rather than services income for purposes of a foreign sales corporation provision of the Code. However, the IRS stated in an Action on Decision (AOD2010-01) that it disagrees with, and will not acquiesce to, the way that the rental versus services framework was applied to the facts in theTidewaterdecision, and in its discussion stated that the time charters at issue inTidewaterwould be treated as producing services income for PFIC purposes. The IRS’s statement with respect toTidewatercannot be relied upon or otherwise cited as precedent by taxpayers. Consequently, in the absence of any binding legal authority specifically relating to the statutory provisions governing PFICs, there can be no assurance that the IRS or a court would not follow theTidewaterdecision in interpreting the PFIC provisions of the Code. Moreover, the market value of our common stock and our publicly traded subsidiaries may be treated as reflecting the value of our assets, and our publicly traded subsidiaries’ assets, respectively, at any given time. Therefore, a decline in the market value of our common stock, or our publicly traded subsidiaries, which is not within our control, may impact the determination of whether we are a PFIC. Nevertheless, based on our and our subsidiaries’ current assets and operations, we intend to take the position that we are not now and have never been a PFIC, and our counsel, Perkins Coie LLP, is of the opinion that it is more likely than not that we are not a PFIC based on applicable law, including the Code, legislative history, published revenue rulings and court decisions, and representations we have made to them regarding the composition of our assets, the source of our income and the nature of our activities and other operations, including:

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

• the income derived from our participation in pooling arrangements and from our other time and voyage charters will be greater than 25% of our total gross income at all relevant times; and

• the gross value of our vessels participating in pooling arrangements and servicing our other time and voyage charters will exceed the gross value of all other assets we own at all relevant times.

An opinion of counsel represents only that counsel’s best legal judgment and does not bind the IRS or the courts. Accordingly, the opinion of Perkins Coie LLP may not be sustained by a court if contested by the IRS. Further, no assurance can be given that we would not constitute a PFIC for any future taxable year if there were to be changes in our or our subsidiaries’ assets, income or operations.

22

As discussed more fully below, if we were to be treated as a PFIC for any taxable year, a U.S. Holder generally would be subject to different taxation rules depending on whether the U.S. Holder makes a timely and effective election to treat us as a “Qualified Electing Fund” (or aQEF election). 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 stock, as discussed below.

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

A U.S. Holder who makes a timely QEF election (or anElecting Holder) must report the Electing Holder’s pro rata share of our ordinary earnings and net capital gain, if any, for each taxable year for which we are a PFIC that ends with or within the Electing Holder’s taxable year, regardless of whether or not the Electing Holder received distributions from us in that year. Such income inclusions would not be eligible for the preferential tax rates applicable to qualified dividend income. The Electing Holder’s adjusted tax basis in our common stock will be increased to reflect taxed but undistributed earnings and profits. Distributions of earnings and profits that were previously taxed will result in a corresponding reduction in the Electing Holder’s adjusted tax basis in our common stock and will not be taxed again once distributed. An Electing Holder generally will recognize capital gain or loss on the sale, exchange or other disposition of our common stock. A U.S. Holder makes a QEF election with respect to any year that we are a PFIC by filing IRS Form 8621 with the U.S. Holder’s timely filed U.S. federal income tax return (including extensions).

If a U.S. Holder has not made a timely QEF election with respect to the first year in the U.S. Holder’s holding period of our common stock during which we qualified as a PFIC, the U.S. Holder may be treated as having made a timely QEF election by filing a QEF election with the U.S. Holder’s timely filed U.S. federal income tax return (including extensions) and, under the rules of Section 1291 of the Code, a “deemed sale election” to include in income as an “excess distribution” (described below) the amount of any gain that the U.S. Holder would otherwise recognize if the U.S. Holder sold the U.S. Holder’s common stock on the “qualification date.” The qualification date is the first day of our taxable year in which we qualified as a “qualified electing fund” with respect to such U.S. Holder. In addition to the above rules, under very limited circumstances, a U.S. Holder may make a retroactive QEF election if the U.S. Holder failed to file the QEF election documents in a timely manner. If a U.S. Holder makes a timely QEF election for one of our taxable years, but did not make such election with respect to the first year in the U.S. Holder’s holding period of our common stock during which we qualified as a PFIC and the U.S. Holder did not make the deemed sale election described above, the U.S. Holder also will be subject to the more adverse rules described below.

A U.S. Holder’s QEF election will not be effective unless we annually provide the U.S. Holder with certain information concerning our income and gain, calculated in accordance with the Code, to be included with the U.S. Holder’s U.S. federal income tax return. We have not provided our U.S. Holders with such information in prior taxable years and do not intend to provide such information in the current taxable year. Accordingly, U.S. Holders will not be able to make an effective QEF election at this time. If, contrary to our expectations, we determine that we are or will be a PFIC for any taxable year, we will provide U.S. Holders with the information necessary to make an effective QEF election with respect to our common stock.

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

If we were to be treated as a PFIC for any taxable year and, as we anticipate, our stock were treated as “marketable stock,” then, as an alternative to making a QEF election, a U.S. Holder would be allowed to make a “mark–to–market” election with respect to our common stock, 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 for the first year a U.S. Holder holds or is deemed to hold our common stock and for which we are a PFIC, the U.S. Holder generally would include as ordinary income in each taxable year that we are a PFIC the excess, if any, of the fair market value of the U.S. Holder’s common stock at the end of the taxable year over the U.S. Holder’s adjusted tax basis in the common stock. The U.S. Holder also would be permitted an ordinary loss in

23

respect of the excess, if any, of the U.S. Holder’s adjusted tax basis in the common stock over the fair market value thereof at the end of the taxable year that we are a PFIC, 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 our common stock would be adjusted to reflect any such income or loss recognized. Gain recognized on the sale, exchange or other disposition of our common stock in taxable years that we are a PFIC would be treated as ordinary income, and any loss recognized on the sale, exchange or other disposition of our common stock in taxable years that we are a PFIC would be treated as ordinary loss to the extent that such loss does not exceed the net mark–to–market gains previously included in income by the U.S. Holder. Because the mark–to–market election only applies to marketable stock, however, it would not apply to a U.S. Holder’s indirect interest in any of our subsidiaries that were also determined to be PFICs.

If a U.S. Holder makes amark-to-market election for one of our taxable years and we were a PFIC for a prior taxable year during which such U.S. Holder held our common stock and for which (a) we were not a QEF with respect to such U.S. Holder and (b) such U.S. Holder did not make a timelymark-to-market election, such U.S. Holder would also be subject to the more adverse rules described below in the first taxable year for which themark-to-market election is in effect and also to the extent the fair market value of the U.S. Holder’s common stock exceeds the U.S. Holder’s adjusted tax basis in the common stock at the end of the first taxable year for which themark-to-market election is in effect.

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

If we were to be treated as a PFIC for any taxable year, a U.S. Holder who does not make either a QEF election or a “mark–to–market” election for that year (aNon–Electing Holder) would be subject to special rules resulting in increased tax liability with respect to (a) any “excess distribution” (i.e., the portion of any distributions received by the Non– Electing Holder on our common stock in a taxable year in excess of 125% 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 our common stock), and (b) any gain realized on the sale, exchange or other disposition of our common stock. Under these special rules:

• the excess distribution or gain would be allocated ratably over theNon-Electing Holder’s aggregate holding period for our common stock;

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

• the amount allocated to each of the other taxable years would be subject to U.S. federal income 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.

Additionally, for each year during which a U.S. Holder holds our common stock, we are a PFIC, and the total value of all PFIC stock that such U.S. Holder directly or indirectly holds exceeds certain thresholds, such U.S. Holder will be required to file IRS Form 8621 with its annual U.S. federal income tax return to report its ownership of our common stock. In addition, if a Non–Electing Holder who is an individual dies while owning our common stock, suchNon-Electing Holder’s successor generally would not receive a step–up in tax basis with respect to such common stock.

24

U.S. Holders are urged to consult their tax advisors regarding the PFIC rules, including the PFIC annual reporting requirements, as well as the applicability, availability and advisability of, and procedure for, making QEF,mark-to-market and other available elections with respect to us and our subsidiaries, and the U.S. federal income tax consequences of making such elections.

Consequences of Possible Controlled Foreign Corporation Classification

If CFC Shareholders (generally, U.S. Holders who each own, directly, indirectly or constructively, 10% or more of the total combined voting power of our outstanding common stock entitled to vote) own directly, indirectly or constructively more than 50% of either the total combined voting power of our outstanding common stock entitled to vote or the total value of all of our outstanding common stock, we generally would be treated as a controlled foreign corporation (or aCFC).

CFC Shareholders are treated as receiving current distributions of their respective share of certain income of the CFC 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. In addition, a person who is or has been a CFC Shareholder may recognize ordinary income on the disposition of shares of the CFC. Although we do not believe we are or will become a CFC, U.S. persons owning 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.

The U.S. federal income tax consequences to U.S. Holders who are not CFC Shareholders would not change in the event we become a CFC in the future.

U.S. Return Disclosure Requirements for U.S. Individual Holders

U.S. Individual Holders who hold certain specified foreign financial assets, including stock in a foreign corporation that is not held in an account maintained by a financial institution, with an aggregate value in excess of $50,000 on the last day of a taxable year, or $75,000 at any time during that taxable year, may be required to report such assets on IRS Form 8938 with their U.S. federal income tax return for that taxable year. This reporting requirement does not apply to U.S. Individual Holders who report their ownership of our common stock under the PFIC annual reporting rules described above. Penalties apply for failure to properly complete and file IRS Form 8938. Investors are encouraged to consult with their tax advisors regarding the possible application of this disclosure requirement to their investment in our common stock.

United States Federal Income Taxation ofNon-U.S. Holders

A beneficial owner of our common stock (other than a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder is a Non–U.S. Holder.

Distributions

In general, a Non–U.S. Holder will not be subject to U.S. federal income tax on distributions received from us with respect to our common stock unless the distributions are effectively connected with theNon-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment that theNon-U.S. Holder maintains in the United States). If a Non–U.S. Holder is engaged in a trade or business within the United States and the distributions are deemed to be effectively connected to that trade or business, theNon-U.S. Holder generally will be subject to U.S. federal income tax on those distributions in the same manner as if it were a U.S. Holder.

Sale, Exchange or Other Disposition of Common Stock

In general, aNon-U.S. Holder is not subject to U.S. federal income tax on any gain resulting from the disposition of our common stock unless (a) such gain is effectively connected with theNon-U.S. Holder’s

25

conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment that theNon-U.S. Holder maintains in the United States) or (b) theNon-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year in which such disposition occurs and meets certain other requirements. If aNon-U.S. Holder is engaged in a trade or business within the United States and the disposition of our common stock is deemed to be effectively connected to that trade or business, theNon-U.S. Holder generally will be subject to U.S. federal income tax on the resulting gain in the same manner as if it were a U.S. Holder.

Information Reporting and Backup Withholding

In general, payments of distributions with respect to, or the proceeds of a disposition of, our common stock to a Non–Corporate U.S. Holder will be subject to information reporting requirements. These payments to a Non–Corporate U.S. Holder also may be subject to backup withholding if the Non–Corporate U.S. Holder:

• fails to timely provide an accurate taxpayer identification number;

• is notified by the IRS that it has failed to report all interest or distributions required to be shown on its 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 on payments made to them within the United States, or through a U.S. payor, by certifying their status on IRS FormW-8BEN,W-8BEN-E,W-8ECI,W-8EXP orW-8IMY, as applicable.

Backup withholding is not an additional tax. Rather, a shareholder generally may obtain a credit for any amount withheld against its liability for U.S. federal income tax (and obtain a refund of any amounts withheld in excess of such liability) by accurately completing and timely filing a U.S. federal income tax return with the IRS.

The following discussion is based upon the opinion of Watson Farley & Williams LLP, 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 and is applicable only to persons who are not citizens of and do not reside in, maintain offices in or engage in business, transactions or operations in the Republic of the Marshall Islands.

Because we and our subsidiaries do not, and we do not expect that we or any of our subsidiaries will, reside in or conduct business, transactions or operations in the Republic of the Marshall Islands, and because we anticipate that all documentation related to any offerings pursuant to this prospectus will be executed outside of the Republic of the Marshall Islands, under current Republic of the Marshall Islands law holders of our common stock will not be subject to Republic of the Marshall Islands taxation or withholding on dividends. In addition, holders of our common stock will not be subject to Republic of the Marshall Islands stamp, capital gains or other taxes on the purchase, ownership or disposition of shares of common stock, and you will not be required by the Republic of the Marshall Islands to file a tax return relating to the shares of common stock.

It is the responsibility of each shareholder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, including the Republic of the Marshall Islands, of its investment in us. Accordingly, each shareholder is urged to consult its tax counsel or other advisor with regard to those matters. Further, it is the responsibility of each shareholder to file all state, local andnon-U.S., as well as U.S. federal, tax returns which may be required of such shareholder.

PLAN OF DISTRIBUTION

We may sell our common stock, preferred stock, convertible preferred stock, debt securities, convertible debt securities and any combination of the foregoing from time to time on a continuous or delayed basis (a) to or through underwriters or dealers, (b) through agents, (c) directly to one or more purchasers or other persons or entities, (d) through a combination of these methods or (e) through other means.

We may enter into hedging transactions with respect to our securities. For example, we may:

• enter into transactions involving short sales of securities by underwriters, brokers or dealers;

• sell securities short and deliver the securities to close out short positions;

• enter into option or other types of transactions that require us to deliver securities to an underwriter, broker or dealer, who will then resell or transfer the securities under this prospectus; or

• loan or pledge securities to an underwriter, broker or dealer, who may sell the securities or, in the event of default, sell the pledged securities.

If underwriters are used to sell securities, we will enter into an underwriting agreement or similar agreement with them at the time of the sale to them. In that connection, underwriters may receive compensation from us in the form of underwriting discounts or commissions and may also receive commissions from purchasers of securities for whom they may act as agent. Any such underwriter, dealer or agent may be deemed to be an underwriter within the meaning of the Securities Act.

The applicable prospectus supplement relating to securities will set forth, among other things:

• the offering terms, including the name or names of any underwriters, dealers or agents;

• the purchase price of the securities and the proceeds to us from such sale;

• any underwriting discounts, concessions, commissions and other items constituting compensation to underwriters, dealers or agents;

• any initial public offering price;

• any discounts or concessions allowed or reallowed or paid by underwriters or dealers to other dealers; and

• any securities exchanges on which the securities may be listed.

If underwriters or dealers are used in the sale, securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions in accordance with the rules of the New York Stock Exchange:

• at a fixed price or prices that may be changed;

• at market prices prevailing at the time of sale;

• at prices related to such prevailing market prices; or

• at negotiated prices.

Securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more of such firms. Unless otherwise set forth in an applicable prospectus supplement, the obligations of underwriters or dealers to purchase the securities will be subject to certain conditions precedent and the underwriters or dealers will be obligated to purchase all the securities if any are purchased. Any public offering price and any discounts or concessions allowed or reallowed or paid by underwriters or dealers to other dealers may be changed from time to time.

27

Securities may be sold directly by us from time to time, at prevailing market prices or otherwise. Securities may also be sold through agents designated by us from time to time, at prevailing market prices or otherwise. Any agent involved in the offer or sale of securities in respect of which this prospectus and a prospectus supplement is delivered will be named, and any commissions payable by us to such agent will be set forth, in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

If so indicated in the prospectus supplement, we will authorize underwriters, dealers or agents to solicit offers from certain specified institutions to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. Such contracts will be subject to any conditions set forth in the prospectus supplement and the prospectus supplement will set forth the commissions payable for solicitation of such contracts. The underwriters and other persons soliciting such contracts will have no responsibility for the validity or performance of any such contracts.

Underwriters, dealers and agents may be entitled under agreements entered into with us to be indemnified by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution by us to payments which they may be required to make. The terms and conditions of such indemnification will be described in an applicable prospectus supplement.

Underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for us in the ordinary course of business.

Any underwriters to whom securities are sold by us for public offering and sale may make a market in such securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any of the securities.

Certain persons participating in any offering of securities may engage in transactions that stabilize, maintain or otherwise affect the price of the securities offered. In connection with any such offering, the underwriters or agents, as the case may be, may purchase and sell the securities in the open market. These transactions may include over-allotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. Stabilizing transactions consist of certain bids or purchases for the purpose of preventing or retarding a decline in the market price of the securities and syndicate short positions involve the sale by the underwriters or agents, as the case may be, of a greater number of the securities than they are required to purchase from us in the offering. The underwriters may also impose a penalty bid, whereby selling concessions allowed to syndicate members or other broker-dealers for the securities sold for their account may be reclaimed by the syndicate if such securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the securities, which may be higher than the price that might otherwise prevail in the open market, and if commenced, may be discontinued at any time. These transactions may be effected on the New York Stock Exchange, in theover-the-counter market or otherwise. These activities will be described in more detail in the applicable prospectus supplement.

SERVICE OF PROCESS AND ENFORCEMENT OF CIVIL LIABILITIES

Teekay Corporation is a Republic of the Marshall Islands corporation. The Republic of the Marshall Islands has a less developed body of securities laws as compared to the United States and provides protections for investors to a significantly lesser extent.

Most of our directors and officers and those of our controlled affiliates are residents of countries other than the United States. Substantially all of our and our subsidiaries’ assets and a substantial portion of the assets of our directors and officers are located outside of the United States. As a result, it may be difficult or impossible for United States investors to effect service of process within the United States upon us, our subsidiaries or our directors and officers or to realize against us or them judgments obtained in United States courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state in the United States. However, we have expressly submitted to the jurisdiction of the U.S. federal and New York state courts sitting in the City of New York for the purpose of any suit, action or proceeding arising under the securities laws of the United States or any state in the United States, and we have appointed Watson Farley & Williams LLP to accept service of process on our behalf in any such action.

Watson Farley & Williams LLP, our counsel providing advice relating to Republic of the Marshall Islands law, has advised us that there is uncertainty as to whether the courts of the Republic of the Marshall Islands would (a) recognize or enforce against us or our directors and officers judgments of courts of the United States based on civil liability provisions of applicable U.S. federal and state securities laws or (b) impose liabilities against us or our directors and officers or those of our controlled affiliates in original actions brought in the Republic of the Marshall Islands, based on these laws.

LEGAL MATTERS

Unless otherwise stated in any applicable prospectus supplement, certain legal matters will be passed upon for us by Perkins Coie LLP. Unless otherwise stated in any applicable prospectus supplement, the validity of the securities and certain other legal matters with respect to the laws of the Republic of the Marshall Islands will be passed upon for us by Watson Farley & Williams LLP. As appropriate, legal counsel representing any underwriters, dealers or agents will be named in the applicable prospectus supplement and may opine as to certain legal matters.
