OVERVIEW
 
Our business is to own oil tankers and we employ a chartering strategy that seeks to capture upside opportunities in the tanker spot market while using fixed-rate time charters to reduce downside risks. As of April 1, 2010, we owned nine Aframax-class crude oil tankers and three Suezmax-class oil tankers, including the Falster Spirit, an Aframax tanker we have agreed to sell for $17.0 million, with delivery to the purchaser expected in mid-April 2010. We were formed by Teekay Corporation (NYSE: TK)—a leading provider of marine services to the global oil and gas industries and the world’s largest operator of medium-sized oil tankers—to acquire from it a fleet of double-hull oil tankers in connection with our initial public offering in December 2007. Our growth strategy focuses on expanding our fleet through accretive acquisitions and seeking to tactically manage our mix of spot and time-charter contracts to maximize dividends on a per-share basis. Through the participation of some of our vessels in pooling arrangements (or pools) managed by subsidiaries of Teekay Corporation and in which certain of its tankers participate, we expect to benefit from Teekay Corporation’s reputation and the scope of Teekay Corporation’s operations in increasing our cash flow. We also expect to benefit from Teekay Corporation’s expertise, relationships and reputation in operating our fleet and pursuing growth opportunities. Teekay Corporation currently holds a majority of the voting power of our common stock.
 
We distribute to our stockholders on a quarterly basis all of our Cash Available for Distribution, subject to any reserves our board of directors may from time to time determine are required for the prudent conduct of our business. Cash Available for Distribution represents our net income (loss) plus depreciation and amortization, unrealized losses from derivatives, non-cash items and any write-offs or other non-recurring items less unrealized gains from derivatives and net income attributable to us for accounting purposes from vessels we acquire from Teekay Corporation in respect of periods before we acquire the vessels but while they and we are under common control with Teekay Corporation. We paid total dividends of $1.40 per share in respect of the four quarters ended December 31, 2009. Since inception, we have paid dividends with respect to nine consecutive fiscal quarters totaling $4.90 per share on a cumulative basis. Please read “Our Dividend Policy and Restrictions on Dividends” on page 6 of the accompanying prospectus.
 
PROPOSED ACQUISITION OF THREE TANKERS
 
Upon the closing of this offering, we will acquire from Teekay Corporation for aggregate consideration of approximately $168.7 million the following vessels (or the Dropdown Vessels):
 
Ø  the 2004-built Kaveri Spirit, a Suezmax tanker currently participating in a Suezmax tanker pool managed by a Teekay Corporation subsidiary;
 
Ø  the 2002-built Yamuna Spirit, a Suezmax tanker currently operating under a fixed-rate, time-charter contract that is scheduled to expire in May 2012 and includes a profit share component (subject to prevailing market rates); and


S-1


Table of Contents

 
Ø the 2005-built Helga Spirit, an Aframax tanker currently operating under a fixed-rate, time-charter contract that is scheduled to expire in October 2010.
 
We will finance the acquisition of the Dropdown Vessels with (a) the net proceeds of this offering, (b) the issuance to Teekay Corporation of unregistered shares of our Class A common stock with an aggregate value of approximately $32.0 million (valued on a per-share basis at the same price we sell shares to the public in this offering) and (c) borrowings under our revolving credit facility for the balance (with interest rates based on LIBOR plus a margin of 0.60 percent). We may have the option of assuming approximately $12.6 million of outstanding debt secured by the Helga Spirit, which would reduce correspondingly our cash purchase price for the vessel and the amount of our borrowings under our revolving credit facility. For purposes of this prospectus we have assumed that this debt will be repaid prior to our acquisition of the Helga Spirit, with no corresponding reduction in the cash purchase price or our borrowings under our revolving credit facility. Please read “Use of Proceeds.”
 
When we acquire the Dropdown Vessels, the total undrawn availability under our revolving credit facility will automatically increase by an additional amount equal to $115.0 million less the amount of funds we borrow under the facility to finance the acquisition. The Kaveri Spirit and Yamuna Spirit currently secure borrowings by Teekay Corporation under a separate tranche of the same revolving credit facility. Upon transfer to us, each vessel’s share of undrawn availability automatically increases the total undrawn availability under our tranche of the revolving credit facility. Giving pro forma effect to this additional availability and a net reduction in availability arising from the sale of the Falster Spirit, as of December 31, 2009, our total undrawn availability under the facility would have been approximately $178.7 million (assuming no exercise by the underwriters of their over-allotment option) based on our assumed public offering price.
 
As a result of the acquisition of the Dropdown Vessels and the sale of the Falster Spirit, our net fleet capacity will increase by approximately 23 percent to a total of approximately 1.8 million deadweight tonnes (or dwt). No drydocking is scheduled for the Dropdown Vessels until 2012, when the Yamuna Spirit is scheduled to drydock. The Falster Spirit was scheduled for drydocking in 2010 and we had planned to reserve $1.55 million from our Cash Available for Distribution for each of 2010 and 2011 for expenditures relating to the Falster Spirit drydocking that will no longer be required.
 
The Conflicts Committee of our board of directors has approved the terms of our acquisition of the Dropdown Vessels from Teekay Corporation.
 
In connection with our initial public offering, Teekay Corporation agreed to offer to us prior to June 18, 2010 the right to purchase from it up to four existing Suezmax tankers. The Yamuna Spirit is the fourth and final of these tankers offered to us. We anticipate further opportunities to expand our fleet through acquisitions of tankers from third parties and additional tankers that Teekay Corporation may offer to us from time to time.
 
Based on the information described above and current spot-tanker rates, we expect the acquisition of the Dropdown Vessels to be accretive to our cash flow per share in 2010.
 
OUR FLEET
 
As of April 1, 2010, we owned nine Aframax tankers (including the Falster Spirit) and three Suezmax tankers. As of that date, five of our Aframax tankers and two of our Suezmax tankers operated under fixed-rate, time-charter contracts with our customers, of which two charter contracts are scheduled to expire in 2010, four in 2011, and one in 2012. The Suezmax fixed-rate charters each have a profit share component. As of April 1, 2010, our remaining four Aframax tankers and one Suezmax tanker participated in an Aframax pool and a Suezmax pool, respectively, each operated by a Teekay Corporation subsidiary and which included 16 and 39 total vessels, respectively. In March 2010 we agreed to sell the 1995-built Falster Spirit, which trades in the spot market, to a third party for $17.0 million. We expect to deliver the Falster Spirit to its purchaser in mid-April 2010.

For the Ganges Spirit and the Yamuna Spirit, the charter contracts entitle us to the first $3,000 per day plus 50 percent thereafter of revenue that the vessel generates in the Suezmax pool beyond the $30,500 daily rate, with the amount of the payment calculated and paid in the second quarter of each year.
 
BUSINESS STRATEGIES
 
Our primary business objective is to increase dividends per share by executing the following strategies:
 
Ø  Expand our Fleet Through Accretive Acquisitions.  We intend to acquire additional oil tankers in a manner that will increase our dividends on a per-share basis. We acquired from Teekay Corporation two Suezmax tankers in April 2008, and we acquired from Teekay Corporation a third Suezmax tanker in June 2009. We intend to use the proceeds from this offering to pay a portion of the purchase price to acquire from Teekay Corporation two additional Suezmax tankers and one Aframax tanker. We also anticipate growing our fleet through acquisitions of tankers from third parties and additional tankers that Teekay Corporation may offer us from time to time. These acquisitions may include crude oil tankers and product tankers.
 
Ø  Tactically Manage our Mix of Spot and Charter Contracts.  We employ a chartering strategy that seeks to capture upside opportunities in the spot market while using fixed-rate time charters to reduce downside risks. We believe that our Manager’s experience operating through cycles in the tanker spot market will assist us in employing this strategy and seeking to maximize our dividends


S-3


Table of Contents

  on a per-share basis. As of April 1, 2010, approximately 54 percent of our anticipated total operating days for the remainder of 2010 were under fixed-rate time-charter contracts at an average time-charter-equivalent (or TCE) rate of approximately $26,800 per day. Giving effect to our proposed acquisition of the Dropdown Vessels and the sale of the Falster Spirit, this fixed percentage would increase to approximately 59 percent and the average TCE rate would be unchanged.
 
Ø  Increase Cash Flow by Participating in Tanker Pools.  Through the participation of a significant number of our vessels in tanker pools operated by Teekay Corporation subsidiaries, we believe we benefit from Teekay Corporation’s reputation and the scope of Teekay Corporation’s operations. We believe that the cash flow we derive over time from operating some of our vessels in these pools exceeds the amount we would otherwise derive by operating these vessels outside of the pools due to higher vessel utilization and daily revenues.
 
Ø  Provide Superior Customer Service by Maintaining High Reliability, Safety, Environmental and Quality Standards.  We believe that energy companies seek transportation partners that have a reputation for high reliability, safety, environmental and quality standards. We seek to leverage Teekay Corporation’s operational expertise and customer base to further expand these relationships with consistent delivery of superior customer service through our Manager.
 
OUR COMPETITIVE STRENGTHS
 
We believe that we possess a number of competitive strengths that will allow us to capitalize on growth opportunities in the oil tanker market, including the following:
 
Ø  Our Manager has Extensive Experience in Fleet Expansion.  Since 1998, Teekay Corporation, of which our Manager is a wholly owned subsidiary, has expanded its fleet from 50 to over 150 vessels. We believe that this fleet expansion experience, to which we have access through our Manager, will continue to prove valuable as we seek to expand our fleet and integrate new assets into our operations.
 
Ø  We have Access to Teekay Corporation’s Extensive Experience in and Knowledge of the Medium-Sized Oil Tanker Market.  With over 30 years in the oil tanker business and with worldwide operations, Teekay Corporation has operated successfully through the inherent cyclicality in the spot market. We believe that our participation in the tanker pools operated by Teekay Corporation subsidiaries and our relationship with our Manager allow us to benefit from Teekay Corporation’s market knowledge and experience in obtaining competitive spot and time-charter rates and in managing our mix of spot and time-charter contracts to maximize our cash flow.
 
Ø  We Believe that our Relationship with Teekay Corporation, with its Prominence and Customer Relationships in the Shipping Industry, Significantly Enhances our Growth Opportunities.  Teekay Corporation has developed an extensive network of long-standing relationships and a strong reputation in the shipping industry. We believe that our relationship with Teekay Corporation significantly enhances the growth of our business through acquisition opportunities (both from Teekay Corporation and third parties) and the pursuit of our chartering strategy.
 
Ø  We have Access to Teekay Corporation’s Expertise in Various Functions Critical to our Vessel Operations.  Our Manager and the other Teekay Corporation subsidiaries that provide services to us have significant technical, financial and commercial capabilities relating to vessel operations and other business matters applicable to our operations. We believe that these services provide strict quality and cost controls to our business and effective safety monitoring of our vessels.
 
Ø  We have Financial Flexibility to Pursue Acquisitions and Expansion Opportunities.  As of December 31, 2009, we had a cash balance of approximately $10.4 million and undrawn availability under our revolving credit facility of approximately $123.7 million. When we acquire the three Dropdown Vessels from Teekay Corporation upon the closing of this offering, the undrawn availability under our revolving credit facility will automatically increase in an amount equal to $115 million less the amount of funds we borrow under the facility to finance the acquisition. Giving

  pro forma effect to this additional availability and a net reduction in availability arising from the sale of the Falster Spirit, as of December 31, 2009, our undrawn availability under the facility would have been approximately $178.7 million (assuming no exercise by the underwriters of their over-allotment option), based on our assumed public offering price. Please read “Use of Proceeds” and “Capitalization.” Based on the anticipated additional amount drawn to partially finance our acquisition of the Dropdown Vessels, net of proceeds received from the sale of the Falster Spirit (which we will use to repay amounts under our revolving credit facility), immediately following these transactions we expect this facility will not be subject to any scheduled principal repayments until November 2015 at the earliest. This repayment schedule may change if we borrow additional amounts under this facility. We believe that our cash balances and availability under our revolving credit facility, in addition to our potential ability to obtain other bank financings and raise equity capital, provides us with financial flexibility to pursue acquisition and expansion opportunities.
 
OUR MANAGER
 
Our Manager provides us with all of our staff other than our Chief Executive Officer, Executive Vice President and Chief Financial Officer. Our board of directors and these executive officers have the authority to hire additional staff as they deem necessary.
 
Our Manager manages our business pursuant to a long-term management agreement (or the Management Agreement), under which it provides to us commercial, technical, administrative and strategic services, other than commercial services provided by other Teekay Corporation subsidiaries that operate tanker pooling arrangements in which some of our vessels participate. Commercial services primarily involve vessel chartering; technical services primarily include vessel maintenance and crewing; administrative services primarily include accounting, legal and financial services; strategic services primarily include providing advice on acquisitions, strategic planning and general management of our business. We pay our Manager a market-based fee for these services that includes reimbursement of the reasonable direct or indirect expenses it incurs in providing us with these services.
 
In order to provide our Manager with an incentive to increase our Cash Available for Distribution, under certain circumstances our Manager is entitled to a performance fee in addition to the basic fee provided in the Management Agreement. If Gross Cash Available for Distribution for a given fiscal year exceeds $3.20 per share of our common stock (or the Incentive Threshold), our Manager generally will be entitled to payment of a performance fee equal to 20 percent of all Gross Cash Available for Distribution for such year in excess of the Incentive Threshold. Gross Cash Available for Distribution represents Cash Available for Distribution without giving effect to any deductions for performance fees and reduced by the amount of any reserves our board of directors may have taken during the applicable fiscal period that have not already reduced Cash Available for Distribution. Commencing January 1, 2008, we have maintained an internal account (or the Cumulative Dividend Account) that reflects, on an aggregate basis, the amount by which our dividends for a fiscal year are greater or less than $2.65 per share. The Cumulative Dividend Account is intended to ensure that our stockholders receive at least $2.65 per share in annualized dividends before any performance fee is paid. We paid our Manager a performance fee of $1.4 million for 2008, but no performance fee was paid for 2009 as dividends per share in respect of the year totaled $1.40.

Shares outstanding immediately after this offering 26,500,000 shares of Class A common stock (27,550,000 shares if the underwriters exercise their over-allotment option in full) and 12,500,000 shares of Class B common stock. Excludes approximately $32.0 million in unregistered shares of Class A common stock to be issued to Teekay Corporation as part of our acquisition of the Dropdown Vessels (valued on a per-share basis at the same price we sell shares to the public in this offering). Assuming a public offering price of $12.99 per share (the last reported sale price of our Class A common stock on the New York Stock Exchange on April 1, 2010), we will issue 2,463,433 unregistered shares of Class A common stock to Teekay Corporation as part of our acquisition of the Dropdown Vessels.
 
Use of proceeds We will use the net proceeds from this offering to pay a portion of the purchase price to acquire the three Dropdown Vessels from Teekay Corporation. Please read “Use of Proceeds” on page S-9 of this prospectus supplement.
 
Cash dividends We paid a cash dividend of $0.26 per share of common stock for the quarter ended December 31, 2009, and total dividends of $1.40 per share in respect of the four quarters ended December 31, 2009.
 
We pay a variable cash dividend each quarter on our Class A and Class B common stock of all our Cash Available for Distribution, subject to any reserves our board of directors may from time to time determine are required for the prudent conduct of our business. There is no guarantee that we will pay any dividends on our shares of common stock in any quarter. For additional information, please read “Our Dividend Policy and Restrictions on Dividends” beginning on page 6 of the accompanying prospectus.
 
Performance fee If Gross Cash Available for Distribution for a given fiscal year exceeds the Incentive Threshold, our Manager, Teekay Tankers Management Services Ltd., under certain circumstances is entitled to payment of a performance fee under the Management Agreement equal to 20 percent of all Gross Cash Available for Distribution for such year in excess of the Incentive Threshold. The performance fee is in addition to the basic fee provided in the Management Agreement. Although the performance fee is payable on an annual basis, we accrue any amounts expected to be payable in respect of the performance fee on a quarterly basis. Accordingly, dividends to our stockholders in any quarter may be reduced due to the performance fee. For additional information, please read “Our Dividend Policy and Restrictions on Dividends” beginning on page 6 of the accompanying prospectus.

Class B common stock Teekay Corporation owns indirectly all of our outstanding shares of Class B common stock, in addition to shares of our Class A common stock. The principal difference between our Class A common stock and our Class B common stock is that each share of Class B common stock entitles the holder thereof to five votes on matters presented to our stockholders, while each share of Class A common stock entitles the holder thereof to only one vote on such matters. However, the voting power of the Class B common stock is limited such that the aggregate voting power of all shares of outstanding Class B common stock can at no time exceed 49 percent of the voting power of our outstanding Class A common stock and Class B common stock, voting together as a single class. The holder of shares of Class B common stock may elect at any time to have such shares converted into shares of Class A common stock on a one-for-one basis. Please read “Description of Capital Stock” on page 8 of the accompanying prospectus for a description of other events triggering a conversion of shares of Class B common stock into shares of Class A common stock.
 
Conflicts of Interest We will use the net proceeds from this offering to pay a portion of the purchase price to acquire the three Dropdown Vessels from Teekay Corporation. Teekay Corporation intends to use a portion of the proceeds from the purchase of the three Dropdown Vessels to repay a portion of the borrowings under Teekay Corporation’s credit facilities. Certain of the underwriters or their affiliates may receive proceeds from this offering if they are lenders under Teekay Corporation’s credit facilities. Because more than 5% of the proceeds of this offering, not including underwriting compensation, may be received by affiliates of the underwriters in this offering, this offering is being conducted in compliance with NASD Rule 2720, as administered by the Financial Industry Regulatory Authority, or FINRA. Pursuant to this rule, the appointment of a qualified independent underwriter is not necessary in connection with this offering, as the offering is of a class of securities having a bona fide public market as contemplated by such rule.
 
Tax considerations We believe that under current U.S. federal income tax law, some portion of the distributions you receive from us will constitute dividends, and if you are an individual citizen or resident of the United States or a U.S. estate or trust and meet certain holding period requirements, then such dividends are expected to be taxable as “qualified dividend income” subject to a maximum 15 percent U.S. federal income tax rate (currently through December 31, 2010). Other distributions will be treated first as a non-taxable return of capital to the extent of your tax basis in your Class A common stock and, thereafter, as capital gain. Please read “Material U.S. Federal Income Tax Considerations” beginning on page S-12 of this prospectus supplement.
 
NYSE Listing Our Class A common stock is listed on the New York Stock Exchange under the symbol “TNK.”
 
Unless we indicate otherwise or the context otherwise requires, all information in this prospectus assumes that the underwriters do not exercise their over-allotment option.

Risk factors
 
Before investing in our shares of Class A common stock, you should carefully consider all of the information included or incorporated by reference into this prospectus. When evaluating an investment in our shares of Class A common stock, you should carefully consider those risks discussed under the caption “Risk Factors” beginning on page 3 of the accompanying prospectus, as well as the discussion of risk factors beginning on page 7 of our Annual Report on Form 20-F for the year ended December 31, 2009, as amended, which is incorporated by reference into this prospectus. If any of these risks were to occur, our business, financial condition, operating results or cash flows could be materially adversely affected. In that case, our ability to pay dividends on shares of our Class A common stock may be reduced, the trading price of our common stock could decline, and you could lose all or part of your investment. In addition, we are subject to the following risks and uncertainties:
 
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. holders.
 
A foreign entity taxed as a corporation for U.S. federal income tax purposes will be treated as a “passive foreign investment company” (or PFIC) for U.S. federal income tax purposes if at least 75.0 percent of its gross income for any taxable year consists of certain types of “passive income,” or at least 50.0 percent of the average value of the entity’s assets produce or are held for the production of those types of “passive income.” For purposes of these tests, “passive income” includes dividends, interest, and 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 U.S. Internal Revenue Code of 1986, as amended (or the Code), and a recent unofficial IRS pronouncement issued to provide guidance to IRS field employees and examiners, which cites the Tidewater decision favorably in support of the conclusion that income derived by foreign taxpayers from time-chartering vessels engaged in the exploration for, or exploitation of, natural resources on the Outer Continental Shelf in the Gulf of Mexico is characterized as leasing or rental income for purposes of the income sourcing provisions of the Code. However, we believe that the nature of our chartering activities, as well as our charter contracts, differ in certain material respects from those at issue in Tidewater. Consequently, 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 other operations following this offering. 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, U.S. holders of our common stock will face adverse U.S. federal income tax consequences. Under the PFIC rules, unless those U.S. holders timely make certain elections available under the Code, such holders would be liable to pay tax at ordinary income tax rates plus interest upon certain distributions and upon any gain from the disposition of our common stock, as if such distribution or gain had been recognized ratably over the U.S. holder’s holding period. Please read “Material U.S. Federal Income Tax Considerations — United States Federal Income Taxation of U.S. Holders — Consequences of Possible PFIC Classification beginning on page S-13 of this prospectus supplement.”

Use of proceeds
 
We expect to receive net proceeds of approximately $86.9 million from the sale of 7,000,000 shares of our Class A common stock in this offering, after deducting underwriting discounts and estimated expenses payable by us. We base this amount on an assumed public offering price of $12.99 per share, the last reported sales price of our Class A common stock on the New York Stock Exchange on April 1, 2010. We expect to receive net proceeds of approximately $100.0 million if the underwriters exercise in full their over-allotment option to purchase additional shares.
 
We will use the net proceeds from this offering, together with the concurrent issuance to Teekay Corporation of unregistered shares of our Class A common stock with an aggregate value of approximately $32.0 million (valued on a per-share basis at the same price we issue shares to the public in this offering), and borrowings under our revolving credit facility for the balance, to acquire the three Dropdown Vessels from Teekay Corporation for aggregate consideration of approximately $168.7 million.
 
Any proceeds from the exercise of the over-allotment option by the underwriters will be used to pay a portion of the consideration for the acquisition of the Dropdown Vessels, which would reduce the amount we would borrow under our revolving credit facility for the acquisition. Borrowings under our revolving credit facility bear interest at a fluctuating rate equal to LIBOR plus a margin. As of April 1, 2010, this interest rate was 0.85 percent.
 
We may have the option of assuming approximately $12.6 million of outstanding debt secured by one of the Dropdown Vessels, the Helga Spirit, which would reduce our cash purchase price for the vessel and the amount of our borrowings under our revolving credit facility. For purposes of this prospectus we have assumed that this debt will repaid prior to our acquisition of the Helga Spirit, with no corresponding reduction in the cash purchase price or our borrowings under our revolving credit facility.

Material tax considerations
 
Material U.S. Federal Income Tax Considerations
 
The following is a discussion of the material U.S. federal income tax considerations that may be relevant to prospective stockholders 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 provisions of the Internal Revenue Code of 1986, as amended (or the Code), existing final and temporary regulations thereunder (or Treasury Regulations), and current administrative rulings and court decisions, all as in effect on the date of this prospectus supplement, and which are subject to change, possibly with retroactive effect. Changes in these authorities may cause the tax consequences to vary substantially from the consequences described below. Unless the context otherwise requires, references in this section to “we,” “our” or “us” are references to Teekay Tankers Ltd.
 
The following summary does not comment on all aspects of U.S. federal income taxation that may be important to particular stockholders in light of their individual circumstances, such as stockholders subject to special tax rules (e.g., financial institutions, insurance companies, broker-dealers, tax-exempt organizations, or former citizens or long-term residents of the United States) or to persons who will hold the common stock as part of a straddle, hedge, conversion, constructive sale or other integrated transaction for U.S. federal income tax purposes, partnerships or their partners, or to persons that have a functional currency other than the U.S. dollar, or that own, actually or under applicable constructive ownership rules, 10% or more of our commons stock all of whom may be subject to tax rules that differ significantly from those summarized below. If a partnership or other entity taxed as a pass-through entity holds our common, stock, the tax treatment of a partner or owner thereof generally will depend upon the status of the partner or owner and upon the activities of the partnership or pass-through entity. If you are a partner in a partnership or owner of a pass-through entity holding our common stock, you should consult your tax advisor.
 
No ruling has been or will be requested from the IRS regarding any matter affecting us or our stockholders. Instead, we will rely on the opinion of Perkins Coie LLP. Unlike a ruling, an opinion of counsel represents only that counsel’s best legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made here may not be sustained by a court if contested by the IRS.
 
This summary does not discuss any U.S. state or local, estate or alternative minimum tax considerations regarding the ownership or disposition of common stock. This summary is written for stockholders that purchase our common stock in connection with this offering and that hold their common stock as a “capital asset” under the Code. Each stockholder is urged to consult its tax advisor regarding the U.S. federal, state, local and other tax consequences of the ownership or disposition of common stock.
 
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 a U.S. citizen or U.S. resident alien, a corporation or other entity taxable as a corporation for U.S. federal income tax purposes, that was created or organized in or under the laws of the United States, any state thereof or the District of Columbia, an estate whose income is subject to U.S. federal income taxation regardless of its source, or 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 U.S. Treasury Regulations to be treated as a United States person.

Material tax considerations
 
 
Distributions
 
Subject to the discussion of passive foreign investment companies (or PFICs) 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 or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our earnings and profits will be treated first as a nontaxable return of capital to the extent of the U.S. Holder’s tax basis in its common stock and thereafter as capital gain. 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. Dividends paid with respect to our common stock generally will be treated as “passive category income” or, in the case of certain types of U.S. Holders, “general category income” for purposes of computing allowable foreign tax credits for U.S. federal income tax purposes.
 
Dividends paid on our common stock to a U.S. Holder who is an individual, trust or estate (or a U.S. Individual Holder) will be treated as “qualified dividend income” that currently is taxable to such U.S. Individual Holder at preferential capital gain tax rates provided that: (i) our common stock is readily tradable on an established securities market in the United States (such as the New York Stock Exchange, on which our common stock is traded); (ii) we are not 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 a PFIC, as discussed below); (iii) the U.S. Individual Holder has owned the common stock for more than 60 days in the 121-day period beginning 60 days before the date on which the common stock becomes ex-dividend; (iv) the U.S. Individual Holder is not under an obligation to make related payments with respect to positions in substantially similar or related property and (v) certain other conditions are met. There is no assurance that any dividends paid on our common stock will be eligible for these preferential rates in the hands of a U.S. Individual Holder. Any dividends paid on our common stock not eligible for these preferential rates will be taxed as ordinary income to a U.S. Individual Holder. In the absence of legislation extending the term of the preferential tax rates for qualified dividend income, all dividends received by a taxpayer in tax years beginning on January 1, 2011 or later will be taxed at ordinary graduated tax rates.
 
Special rules may apply to any “extraordinary dividend” paid by us. An extraordinary dividend is, generally, a dividend with respect to a share of stock if the amount of the dividend is equal to or in excess of 10.0 percent of a stockholder’s adjusted basis (or fair market value in certain circumstances) in such stock. If we pay an “extraordinary dividend” on our common stock that is treated as “qualified dividend income,” then any loss derived by a U.S. Individual Holder from the sale or exchange of such common stock will be treated as long-term capital loss to the extent of such dividend.
 
Newly enacted legislation requires certain U.S. holders who are individuals, estates or trusts to pay a 3.8 percent tax on, among other things, dividends for taxable years beginning after December 31, 2012. U.S. holders should consult their tax advisors regarding the effect, if any, of this legislation on their ownership 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 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: (i) at least 75.0 percent of its gross income is “passive” income; or (ii) at least 50.0 percent of the average value of its assets is attributable to assets that produce passive income or are held for the production of passive income. For purposes of these tests, “passive income” includes dividends, interest, and gains from the sale or exchange of investment property and rents and royalties, other than rents and royalties that are received from unrelated parties

Material tax considerations
 
 
in connection with the active conduct of a trade or business. For purposes of these tests, 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 Code, and a recent unofficial IRS pronouncement issued to provide guidance to IRS field employees and examiners, which cites the Tidewater decision favorably in support of the conclusion that income derived by foreign taxpayers from time-chartering vessels engaged in the exploration for, or exploitation of, natural resources on the Outer Continental Shelf in the Gulf of Mexico is characterized as leasing or rental income for purposes of the income-sourcing provisions of the Code. However, we believe that the nature of our and our subsidiaries’ chartering activities, as well as our and our subsidiaries’ charter contracts, differ in certain material respects from those at issue in Tidewater. Consequently, 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 following this offering including:
 
Ø  The income derived from our participation in pooling arrangements and from our other time and voyage charters will be greater than 25.0 percent of our total gross income at all relevant times; and
 
Ø  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 assets, income or operations.
 
Current law provides that dividends received by a U.S. Individual Holder from a qualified foreign corporation are subject to U.S. federal income tax at preferential rates through 2010. However, if we are classified as a PFIC for a taxable year in which we pay a dividend or the immediately preceding taxable year, we would not be considered a qualified foreign corporation, and a U.S. Individual Holder receiving such dividends would not be eligible for the reduced rate of U.S. federal income tax.
 
Additionally, as discussed more fully below, if we were to be treated as a PFIC for any taxable year, a U.S. Holder 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” (a QEF 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. In addition, U.S. Holders of PFICs may be subject to additional reporting requirements.
 
Taxation of U.S. Holders Making a Timely QEF Election. If a U.S. Holder makes a timely QEF election (an Electing Holder), the Electing Holder must report each year for U.S. federal income tax purposes the Electing Holder’s pro rata share of our ordinary earnings and net capital gain, if any, for our taxable years that end 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 the 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 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 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 holder’s holding period of our common stock during which we qualified as a PFIC, the holder may be treated as having made a timely QEF election by filing a QEF election with the 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 holder would otherwise recognize if the holder sold the 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 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 holder’s holding period of our common stock during which we qualified as a PFIC and the holder did not make the deemed sale election described above, the holder will also 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 holder with certain information concerning the Company’s income and gain, calculated in accordance with the Code, to be included with the 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, you 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 holder’s adjusted tax basis in the common stock. The U.S. Holder also would be permitted an ordinary loss in 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 the holder’s 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 the 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 a mark-to-market election for one of our taxable years and we were a PFIC for a prior taxable year during which such holder held our common stock and for which (i) we were not a QEF with respect to such holder and (ii) such holder did not make a timely mark-to-market election, such holder would also be subject to the more adverse rules described below in the first taxable year for which the mark-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 holder’s adjusted tax basis in the common stock at the end of the first taxable year for which the mark-to-market election is in effect.
 
Taxation of U.S. Holders Not Making a Timely QEF or Mark-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 (a Non-Electing Holder) would be subject to special rules resulting in increased tax liability with respect to (1) 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 125.0 percent of the average annual distributions received by the Non-Electing Holder in the three preceding taxable years, or, if shorter, the Non-Electing Holder’s holding period for the common stock), and (2) any gain realized on the sale, exchange or other disposition of the stock. Under these special rules:
 
Ø  the excess distribution or gain would be allocated ratably over the Non-Electing Holder’s aggregate holding period for the common stock;
 
Ø  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 the Non-Electing Holder would be taxed as ordinary income in the current taxable year;
 
Ø  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 taxpayers for that year; and an interest charge for the deemed deferral benefit would be imposed with respect to the resulting tax attributable to each such other taxable year.
 
If we were treated as a PFIC for any taxable year and a Non-Electing Holder who is an individual dies while owning our common stock, such holder’s successor generally would not receive a step-up in tax basis with respect to such stock.
 
U.S. Holders are urged to consult their own tax advisors regarding the applicability, availability and advisability of, and procedure for, making QEF, Mark-to-Market Elections and other available elections with respect to us, and the U.S. federal income tax consequences of making such elections.
 
Sale, exchange or other disposition of common stock
 
Assuming we do not constitute a PFIC or CFC for any taxable year, a U.S. Holder generally will recognize taxable 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 will be treated as long-term capital gain or loss if the U.S. Holder’s holding period is greater than one year at the time of the sale, exchange or other disposition, and subject to preferential capital gain tax rates. Such capital gain or loss will generally be treated as U.S.-source gain or loss, as applicable, for U.S. foreign tax credit purposes. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations.
 
Newly enacted legislation requires certain U.S. holders who are individuals, estates or trusts to pay a 3.8 percent tax on, among other things, capital gains from the sale or other disposition of stock for taxable years beginning after December 31, 2012. U.S. holders should consult their tax advisors regarding the effect, if any, of this legislation on their disposition of our common stock.
 
United States Federal Income Taxation of Non-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
 
Distributions we make to a Non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax if the Non-U.S. Holder is not engaged in a U.S. trade or business. If the Non-U.S. Holder is engaged in a U.S. trade or business, distributions we make will be subject to U.S. federal income tax to the extent those distributions constitute income effectively connected with that Non-U.S. Holder’s U.S. trade or business. However, distributions made to a Non-U.S. Holder that is engaged in a trade or business may be exempt from taxation under an income tax treaty if the income represented thereby is not attributable to a U.S. permanent establishment maintained by the Non-U.S. Holder.
 
Sale, exchange or other disposition of common stock
 
The U.S. federal income taxation of Non-U.S. Holders on any gain resulting from the disposition of our common stock generally is the same as described above regarding distributions. However, an individual Non-U.S. Holder may be subject to tax on gain resulting from the disposition of our common stock if the holder 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.
 
Backup withholding and information reporting
 
In general, payments of distributions or the proceeds of a disposition of 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:
 
Ø  fails to timely provide an accurate taxpayer identification number;
 
Ø  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
 
Ø  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 within the United States by certifying their status on IRS Form W-8BEN, W-8ECI or W-8IMY, as applicable.
 
Backup withholding is not an additional tax. Rather, a stockholder generally may obtain a credit for any amount withheld against its liability for U.S. federal income tax (and a refund of any amounts withheld in excess of such liability) by accurately completing and timely filing a return with the IRS.

We estimate that the total expenses of this offering payable by us, not including the underwriting discounts and commissions, will be approximately $385,000.
 
Indemnification
 
We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the U.S. Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make because of any of those liabilities.
 
We and each of our officers and directors, including nominees for directors, have agreed that, for a period of 60 days from the date of this prospectus, we and they will not, without the prior written consent of UBS Securities LLC, Citigroup Global Markets Inc., J.P. Morgan Securities Inc. and Deutsche Bank Securities Inc., dispose of or hedge any shares of our Class A common stock or any securities convertible into or exchangeable for our Class A common stock, subject to certain exceptions. Teekay Corporation has agreed to a similar lock-up period for the shares of our Class A common stock and our Class B common stock held by it or its subsidiaries other than us that will extend for 60 days from the date of this prospectus. UBS Securities LLC, Citigroup Global Markets Inc., J.P. Morgan Securities Inc. and Deutsche Bank Securities Inc., in their sole discretion, may release any of the securities subject to these lock-up agreements at any time without notice. The representatives have no present intent or arrangement to release any of the securities subject to these lock-up agreements. The release of any lock-up is considered on a case-by-case basis. Factors in deciding whether to release common stock may include the length of time before the lock-up period expires, the number of shares of common stock involved, the reason for the requested release, market conditions, the trading price of our Class A common stock, historical trading volume of our Class A common stock and whether the person seeking the release is an officer, director or affiliate of us.
 
The restricted period described in the preceding paragraph will be extended if:
 
Ø  during the last 17 days of the restricted period we issue an earnings release or announce material news or a material event; or
 
Ø  prior to the expiration of the restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the restricted period,
 
in which case the restrictions described in the preceding paragraph will continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or event.
 
NYSE Stock Market Listing
 
Our Class A common stock is listed on the NYSE under the symbol “TNK.”
 
PRICE STABILIZATION, SHORT POSITIONS
 
In connection with this offering, UBS Securities LLC, on behalf of the underwriters, may engage in activities that stabilize, maintain or otherwise affect the price of our Class A common stock, including:
 
Ø  stabilizing transactions;
 
Ø  short sales;
 
Ø  purchases to cover positions created by short sales;
 
Ø  imposition of penalty bids; and
 
Ø  syndicate covering transactions.
 
Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of our Class A common stock while this offering is in progress. These transactions may also include making short sales of our Class A common stock, which involve the sale

Underwriting
 
 
by the underwriters of a greater number of shares of Class A common stock than they are required to purchase in this offering, and purchasing shares of Class A common stock on the open market to cover positions created by short sales. Short sales may be “covered short sales,” which are short positions in an amount not greater than the underwriters’ over-allotment option referred to above, or may be “naked short sales,” which are short positions in excess of that amount.
 
The underwriters may close out any covered short position by either exercising their over-allotment option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option.
 
Naked short sales are short sales made in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Class A common stock in the open market that could adversely affect investors who purchased in this offering.
 
The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representative has repurchased shares sold by or for the account of that underwriter in stabilizing or short covering transactions.
 
As a result of these activities, the price of our Class A common stock may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. The underwriters may carry out these transactions on the NYSE, in the over-the-counter market or otherwise.
 
AFFILIATIONS
 
Certain of the underwriters and their affiliates from time to time have performed investment banking, commercial banking and advisory services for our affiliates Teekay Corporation, Teekay LNG Partners L.P. and Teekay Offshore Partners L.P., for which they have received customary fees and expenses. The underwriters and their affiliates may from time to time perform investment banking and advisory services for us and our affiliates, including Teekay Corporation, and in the ordinary course of business for which they may in the future receive customary fees and expenses.
 
Conflicts of Interest
 
Affiliates of Citigroup Global Markets Inc. and Deutsche Bank Securities Inc. are, and affiliates of certain other underwriters may be, lenders under Teekay Corporation’s credit facilities. We will use the net proceeds from this offering to pay a portion of the purchase price to acquire the three Dropdown Vessels from Teekay Corporation. Teekay Corporation intends to use a portion of the proceeds from the purchase of the three Dropdown Vessels to repay a portion of the borrowings under Teekay Corporation’s credit facilities. Certain of the underwriters or their affiliates may receive proceeds from this offering if they are lenders under Teekay Corporation’s credit facilities. Because more than 5% of the proceeds of this offering, not including underwriting compensation, may be received by affiliates of the underwriters in this offering, this offering is being conducted in compliance with NASD Rule 2720, as administered by the Financial Industry Regulatory Authority, or FINRA. Pursuant to this rule, the appointment of a qualified independent underwriter is not necessary in connection with this offering, as the offering is of a class of securities having a bona fide public market as contemplated by such rule.
 
A prospectus in electronic format may be made available on the web sites maintained by one or more of the underwriters. The representatives may agree to allocate a number of shares of our Class A common

stock to underwriters for sale to their online brokerage account holders. The representatives will allocate shares of our Class A common stock to underwriters that may make Internet distributions on the same basis as other allocations. In addition, shares of our Class A common stock may be sold by the underwriters to securities dealers who resell shares of our Class A common stock to online brokerage account holders.
 
The shares of our Class A common stock are offered for sale in those jurisdictions in the United States, Europe, the United Kingdom and elsewhere where it is lawful to make such offers.

This document has not been registered as a prospectus with the Monetary Authority of Singapore and in Singapore, the offer and sale of our securities is made pursuant to exemptions provided in sections 274 and 275 of the Securities and Futures Act, Chapter 289 of Singapore (or SFA). Accordingly, this prospectus and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of our securities may not be circulated or distributed, nor may our securities be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor as defined in Section 4A of the SFA pursuant to Section 274 of the SFA, (ii) to a relevant person as defined in section 275(2) of the SFA pursuant to Section 275(1) of the SFA, or any person pursuant to Section 275(1A) of the SFA, and in accordance with the conditions specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA, in each case subject to compliance with the conditions (if any) set forth in the SFA. Moreover, this document is not a prospectus as defined in the SFA. Accordingly, statutory liability under the SFA in relation to the content of prospectuses would not apply. Prospective investors in Singapore should consider carefully whether an investment in our securities is suitable for them.

(1)  to an institutional investor (for corporations under Section 274 of the SFA) or to a relevant person defined in Section 275(2) of the SFA, or any person pursuant to an offer that is made on terms that such shares of that corporation or such rights and interest in that trust are acquired at a consideration of not less than S$200,000 (or its equivalent in a foreign currency) for each transaction, whether such amount is to be paid for in cash or by exchange of securities or other assets, and further for corporations, in accordance with the conditions, specified in Section 275 of the SFA;
 
(2)  where no consideration is given for the transfer; or
 
(3)  where the transfer is by operation of law.

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. 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.
 
These and other forward-looking statements are subject to the risks, uncertainties and assumptions, including those risks discussed in “Risk Factors” set forth in this prospectus and those risks discussed in other reports we file with the SEC and that are incorporated into this prospectus by reference, including, without limitation, our Annual Report on Form 20-F for the fiscal year ended December 31, 2008. 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.
 
Forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events affecting us and, therefore, involve a number of risks and uncertainties, including those risks discussed in “Risk Factors” and otherwise incorporated by reference into this prospectus. 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. Further, 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.

TEEKAY TANKERS LTD.
 
Our business is to own oil tankers and we employ a chartering strategy that seeks to capture upside opportunities in the tanker spot market while using fixed-rate time charters to reduce downside risks. We were formed by Teekay Corporation (NYSE: TK) — a leading provider of marine services to the global oil and gas industries and the world’s largest operator of medium-sized oil tankers — to acquire from it a fleet of double-hull oil tankers in connection with our initial public offering in December 2007. As of the date of this prospectus our fleet includes nine Aframax-class tankers and two Suezmax-class tankers. Our growth strategy focuses on expanding our fleet through accretive acquisitions and seeking to tactically manage our mix of spot and time-charter contracts to maximize dividends on a per-share basis. Through the participation of a significant number of our vessels in pooling arrangements managed by subsidiaries of Teekay Corporation and in which certain of its tankers participate, we expect to benefit from Teekay Corporation’s reputation and the scope of Teekay Corporation’s operations in increasing our cash flow. We also expect to benefit from Teekay Corporation’s expertise, relationships and reputation in operating our fleet and pursuing growth opportunities. Teekay Corporation currently holds a majority of the voting power of our common stock.
 
We distribute to our stockholders on a quarterly basis all of our Cash Available for Distribution, subject to any reserves our board of directors may from time to time determine are required for the prudent conduct of our business. Cash Available for Distribution represents our net income (loss) plus depreciation and amortization, unrealized losses from derivatives, non-cash items and any write-offs or other non-recurring items less unrealized gains from derivatives.
 
Our operations are managed by our Manager, under the supervision of our executive officers and board of directors. We have entered into a long-term management agreement (the Management Agreement) pursuant to which our Manager and its affiliates provide to us commercial, technical, administrative and strategic services. We pay our Manager a market-based fee for these services. In order to provide our Manager with an incentive to increase our Cash Available for Distribution, we have agreed to pay a performance fee to our Manager under certain circumstances, in addition to the basic fee provided in the Management Agreement.
 
We are incorporated under the laws of the Republic of The Marshall Islands as Teekay Tankers Ltd. Our principal executive offices are located at 4th Floor, Belvedere Building, 69 Pitts Bay Road, Hamilton HM 08, Bermuda, and our phone number is (441) 298-2530. Our principal operating office is located at Suite 2000, Bentall 5, 550 Burrard Street, Vancouver, British Columbia, Canada, V6C 2K2, and our telephone number at such address is (604) 683-3529.

RISK FACTORS
 
An investment in our Class A common stock involves a high degree of risk. When evaluating an investment in our Class A common stock, you should carefully consider the following risk factors together with all other information included in this prospectus, including those risks discussed under the caption “Risk Factors” in our latest Annual Report on Form 20-F filed with the SEC, which are incorporated by reference into this prospectus, and information included in any applicable prospectus supplement.
 
If any of these risks were to occur, our business, financial condition, operating results or cash flows could be materially adversely affected. In that case, our ability to pay dividends on shares of our Class A common stock may be reduced, the trading price of our Class A common stock could decline, and you could lose all or part of your investment.
 
If the stock price of our Class A common stock fluctuates after any offering related to this prospectus, you could lose a significant part of your investment.
 
The market price of our Class A common stock may be influenced by many factors, many of which are beyond our control, including those described under the caption “Risk Factors” in our latest Annual Report on Form 20-F filed with the SEC, and the following:
 
  •  the failure of securities analysts to publish research about us after the offering, or analysts making changes in their financial estimates;
 
  •  announcements by us or our competitors of significant contracts, acquisitions or capital commitments;
 
  •  variations in quarterly operating results;
 
  •  general economic or financial market conditions;
 
  •  terrorist acts;
 
  •  future sales of our Class A common stock or other securities; and
 
  •  investors’ perception of us and the seaborne oil transportation industry.
 
As a result of these factors, investors in our Class A common stock may not be able to resell their shares at or above the offering price. These broad market and industry factors may materially reduce the market price of our Class A common stock regardless of our operating performance.
 
Anti-takeover provisions in our organizational documents could make it difficult for our stockholders to replace or remove our current board of directors or have the effect of discouraging, delaying or preventing a merger or acquisition, which may adversely affect the market price of our Class A common stock.
 
Several provisions of our articles of incorporation and bylaws could make it difficult for our stockholders to change the composition of our board of directors, preventing them from changing the composition of management. In addition, the same provisions may discourage, delay or prevent a merger or acquisition that our stockholders may consider favorable.
 
These provisions include:
 
  •  a dual-class common stock structure that currently gives Teekay Corporation and its affiliates control over all matters requiring stockholder approval, including the election of directors and significant corporate transactions, such as a merger or other sale of our company or its assets;
 
  •  authorizing our board of directors to issue “blank check” preferred shares without stockholder approval;
 
  •  prohibiting cumulative voting in the election of directors;
 
  •  authorizing the removal of directors, with or without cause, only by the affirmative vote of the holders of a majority of the voting power of our outstanding capital stock or by directors constituting at least two-thirds of the entire board of directors, unless Teekay Corporation and its affiliates no longer hold a majority of the


3


Table of Contents

  voting power of our outstanding capital stock, in which case directors may only be removed for cause and only by the affirmative vote of the holders of not less than 80% of the total voting power of our outstanding capital stock;
 
  •  limiting the persons who may call special meetings of stockholders; and
 
  •  establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings.
 
These anti-takeover provisions could substantially impede the ability of our Class A common stockholders to benefit from a change in control and, as a result, may adversely affect the market price of our Class A common stock and your ability to realize any potential change-in-control premium.
 
We may issue additional shares of Class A common stock, Class B common stock or other securities without your approval, which would dilute your ownership interests and may depress the market price of the Class A common stock.
 
We may issue additional shares of Class A common stock, Class B common stock and other equity securities of equal or senior rank, without stockholder approval, in a number of circumstances.
 
The issuance by us of additional shares of Class A common stock, Class B common stock or other equity securities of equal or senior rank will have the following effects:
 
  •  our existing stockholders’ proportionate ownership interest in us will decrease;
 
  •  the amount of cash available for dividends payable on our common stock may decrease;
 
  •  the relative voting strength of each previously outstanding share may be diminished; and
 
  •  the market price of our Class A common stock may decline.
 
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. holders.
 
A foreign entity taxed as a corporation for U.S. federal income tax purposes will be treated as a “passive foreign investment company” (or PFIC) for U.S. federal income tax purposes if at least 75.0% of its gross income for any taxable year consists of certain types of “passive income,” or at least 50.0% of the average value of the entity’s assets produce or are held for the production of those types of “passive income.” For purposes of these tests, “passive income” includes dividends, interest, and 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. For purposes of these tests, income derived from the performance of services does not constitute “passive income.” While there are legal uncertainties involved in this determination, our counsel, Perkins Coie LLP, is of the opinion that it is more likely than not that we would not be treated as a PFIC based on certain representations that we have made to them regarding the composition of our assets, the source of our income, and the nature of our activities and other operations following this offering. In addition to these representations, the opinion of Perkins Coie LLP that it is more likely than not that we would not be a PFIC is based principally on the position that at least a majority, if not all, of the gross income we derive from our time and voyage charters (as a participant in one of our pooling arrangements or otherwise) is services income, rather than rental income.
 
There is, however, no direct legal authority under the PFIC rules addressing our method of operation and, therefore, no assurance can be given that the IRS will accept this position 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. Moreover, a recent decision of the United States Court of Appeals for the Fifth Circuit in Tidewater Inc. v. United States, No. 08-30268 (5th Cir. Apr. 13, 2009) held that income derived from certain time-chartering activities should be treated as rental income rather than services income. However, the issues in this case arose under the foreign sales corporation rules of the U.S. Internal Revenue Code of 1986, as amended (or the Code), and did not concern the PFIC rules. In addition, the court’s ruling was contrary to the position of the U.S. Internal Revenue Service (or IRS) that the time-charter income should be treated as services income. As a result, it is uncertain whether the principles of the Tidewater decision


4


Table of Contents

would be applicable to our operations. However, if the principles of the Tidewater decision were applicable to all of our operations, Perkins Coie LLP is of the opinion that we likely would be treated as a PFIC.
 
If the IRS were to find that we are or have been a PFIC for any taxable year, U.S. stockholders will face adverse tax consequences. Under the PFIC rules, unless those stockholders make certain elections available under the Code, such stockholders would be taxable at ordinary income tax rates rather than the special 15% tax rate on our dividends, and would be liable to pay U.S. federal income tax at the ordinary income tax rates plus interest upon certain distributions and upon any gain from the disposition of our common stock, as if such distribution or gain had been recognized ratably over the stockholder’s holding period. Please read “Material U.S. Federal Income Tax Considerations — U.S. Federal Income Taxation of U.S. Holders — Consequences of Possible PFIC Classification.”

USE OF PROCEEDS
 
Unless we specify otherwise in any prospectus supplement, we will use the net proceeds from our sale of securities covered by this prospectus for general corporate purposes, which may include, among other things:
 
  •  paying or refinancing all or a portion of our indebtedness outstanding at the time; and
 
  •  funding working capital, capital expenditures or acquisitions.
 
The actual application of proceeds from the sale of any particular offering of securities covered by this prospectus will be described in the applicable prospectus supplement relating to the offering.
 
OUR DIVIDEND POLICY AND RESTRICTIONS ON DIVIDENDS
 
You should read the following discussion of our dividend policy and restrictions on dividends in conjunction with specific assumptions included in this section. In addition, you should read “Forward-Looking Statements” and “Risk Factors” for information regarding statements that do not relate strictly to historical or current facts and certain risks inherent in our business.
 
Our Dividend Policy
 
Our dividend policy reflects a basic judgment that our stockholders will be better served by our distributing our Cash Available for Distribution rather than by our retaining it. We believe that we will generally finance any capital expenditures from external financing sources rather than cash flows from operations.
 
Our board of directors has adopted a dividend policy to pay a variable quarterly dividend equal to our Cash Available for Distribution during the previous quarter, subject to any reserves our board of directors may from time to time determine are required. If we declare a dividend in respect of a quarter in which an equity issuance has taken place, we may choose to calculate the dividend per share by dividing our Cash Available for Distribution for this quarter by the weighted-average number of shares outstanding over the quarter and, if required, borrow additional amounts to permit us to pay this dividend amount on each share outstanding at the end of the quarter. Dividends are paid equally on a per-share basis between our Class A common stock and our Class B common stock. Cash Available for Distribution represents our net income (loss) plus depreciation and amortization, unrealized losses from derivatives, non-cash items and any write-offs or other non-recurring items less unrealized gains from derivatives.
 
Limitations on Dividends and Our Ability to Change Our Dividend Policy
 
There is no guarantee that our stockholders will receive quarterly dividends from us. Our dividend policy may be changed at any time by our board of directors and is subject to certain restrictions, including:
 
  •  Our stockholders have no contractual or other legal right to receive dividends.
 
  •  Our board of directors has authority to establish reserves for the prudent conduct of our business, after giving effect to contingent liabilities, the terms of our credit facilities, our other cash needs and the requirements of Marshall Islands law. The establishment of these reserves could result in a reduction in dividends to you.
 
  •  Our board of directors may modify or terminate our dividend policy at any time. Even if our dividend policy is not modified or revoked, the amount of dividends we pay under our dividend policy and the decision to pay any dividend is determined by our board of directors.
 
  •  Marshall Islands law generally prohibits the payment of a dividend when a company is insolvent or would be rendered insolvent by the payment of such a dividend or when the declaration or payment would be contrary to any restriction contained in the company’s articles of incorporation. Dividends may be declared and paid out of surplus only, but if there is no surplus, dividends may be declared or paid out of the net profits for the fiscal year in which the dividend is declared and for the preceding fiscal year.


6


Table of Contents

 
  •  We may lack sufficient cash to pay dividends due to decreases in net voyage revenues or increases in operating expenses, principal and interest payments on outstanding debt, tax expenses, working capital requirements, capital expenditures or other anticipated or unanticipated cash needs.
 
  •  Our dividend policy will be affected by restrictions on distributions under our credit facilities, which contain material financial tests and covenants that must be satisfied. If we are unable to satisfy these restrictions included in the credit facilities or if we are otherwise in default under the facilities, we would be prohibited from making cash distributions to you, notwithstanding our stated cash dividend policy.
 
  •  While we intend that future acquisitions to expand our fleet will enhance our ability to pay dividends over time, acquisitions could limit our Cash Available for Distribution.
 
Our ability to make distributions to our stockholders will depend upon the performance of our ship-owning subsidiaries, which are our principal cash-generating assets, and their ability to distribute funds to us. The ability of our ship-owning or other subsidiaries to make distributions to us may be restricted by, among other things, the provisions of existing or future indebtedness, applicable corporate or limited liability company laws and other laws and regulations.
 
If Gross Cash Available for Distribution for a given fiscal year exceeds $3.20 per share of our common stock (or the Incentive Threshold), our Manager generally will be entitled to payment of a performance fee under the Management Agreement equal to 20% of all Gross Cash Available for Distribution for such year in excess of the Incentive Threshold. Gross Cash Available for Distribution represents Cash Available for Distribution without giving effect to any deductions for performance fees and reduced by the amount of any reserves our board of directors may have taken during the applicable fiscal period that have not already reduced Cash Available for Distribution. Although the performance fee is payable on an annual basis, we accrue any amounts expected to be payable in respect of the performance fee on a quarterly basis. Accordingly, dividends to our stockholders in any quarter may be reduced due to the performance fee. Commencing January 1, 2008, we have maintained an internal account (or the Cumulative Dividend Account) that reflects, on an aggregate basis, the amount by which our dividends for a fiscal year are greater or less than $2.65 per share (subject to adjustments for stock dividends, splits, combinations and similar events). The Cumulative Dividend Account is intended to ensure that our stockholders receive at least $2.65 per share in annualized dividends before any performance fee is paid. We have a limited operating history upon which to rely with respect to whether we will have sufficient cash available to pay for dividends on our common stock. In addition, the tanker charter market is highly volatile, and we cannot accurately predict the amount of cash distributions, if any, that we may make in any period. The extent to which we employ our vessels in the spot market may increase the volatility of our dividends. Factors beyond our control may also affect the charter market for our vessels, our charterers’ ability to satisfy their contractual obligations to us, and our voyage and operating expenses.

Common Stock
 
Voting Rights
 
Holders of our Class A and Class B common stock have identical rights, except that holders of our Class A common stock are entitled to one vote per share and holders of our Class B common stock are entitled to five votes per share. However, the voting power of the Class B common stock is limited such that the aggregate voting power of all shares of outstanding Class B common stock can at no time exceed 49% of the voting power of our outstanding Class A common stock and Class B common stock, voting together as a single class. Except as otherwise provided by the Business Corporations Act of the Republic of The Marshall Islands (or the Marshall Islands Act), holders of shares of Class A common stock and Class B common stock will vote together as a single class on all matters submitted to a vote of stockholders, including the election of directors.
 
Marshall Islands law generally provides that the holders of a class of stock are entitled to a separate class vote on any proposed amendment to our articles of incorporation that would change the aggregate number of authorized shares or the par value of that class of shares or alter or change the powers, preferences or special rights of that class so as to affect it adversely.
 
Dividends
 
Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of Class A common stock and Class B common stock shall be entitled to share equally in any dividends that our board of directors may declare from time to time out of funds legally available for dividends. In the event a dividend is paid in the form of shares of common stock or rights to acquire shares of common stock, the holders of Class A common stock shall receive Class A common stock, or rights to acquire Class A common stock, as the case may be, and the holders of Class B common stock shall receive Class B common stock, or rights to acquire Class B common stock, as the case may be.
 
Marshall Islands law generally prohibits the payment of a dividend when a company is insolvent or would be rendered insolvent by the payment of such a dividend or when the declaration or payment would be contrary to any restrictions contained in the company’s articles of incorporation. Dividends may be declared and paid out of surplus only, but if there is no surplus, dividends may be declared or paid out of the net profits for the fiscal year in which the dividend is declared and for the preceding fiscal year.
 
Liquidation Rights
 
Upon our liquidation, dissolution or winding-up, the holders of Class A common stock and Class B common stock shall be entitled to receive the same amount per share of common stock of all our assets remaining after the payment of any liabilities and the satisfaction of any liquidation preferences on any outstanding preferred stock.
 
Conversion
 
Shares of our Class A common stock are not convertible into any other shares of our capital stock.

Table of Contents

Each share of Class B common stock is convertible at any time at the option of the holder thereof into one share of Class A common stock. In addition:
 
  •  upon any transfer of shares of Class B common stock to a holder other than Teekay Corporation (or any of its affiliates or any successor to Teekay Corporation’s business or to all or substantially all of its assets), such transferred shares of Class B common stock shall automatically convert into Class A common stock upon such transfer; and
 
  •  all shares of our Class B common stock will automatically convert into shares of our Class A common stock if the aggregate number of outstanding shares of Class A common stock and Class B common stock beneficially owned by Teekay Corporation and its affiliates falls below 15% of the aggregate number of outstanding shares of our common stock.
 
All such conversions will be effected on a one-for-one basis.
 
Once converted into Class A common stock, shares of Class B common stock shall not be reissued. No class of common stock may be subdivided or combined unless the other class of common stock concurrently is subdivided or combined in the same proportion and in the same manner.
 
Other Rights
 
Holders of our common stock do not have redemption or preemptive rights to subscribe for any of our securities. 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 in the future.
 
Preferred Stock
 
Our articles of incorporation authorize our board of directors to establish one or more series of preferred stock and to determine, with respect to any series of preferred stock, the terms and rights of that series, including:
 
  •  the designation of the series;
 
  •  the number of shares of the series;
 
  •  the preferences and relative, participating, option or other special rights, if any, and any qualifications, limitations or restrictions of such series; and
 
  •  the voting rights, if any, of the holders of the series.
 
Directors
 
Our directors are elected by a plurality of the votes cast by stockholders entitled to vote. There is no provision for cumulative voting.
 
Our articles of incorporation provide that our board of directors must consist of at least three members. Stockholders may change the number of directors only by the affirmative vote of holders of a majority of the voting power of all outstanding shares of our capital stock. However, from and after the date that Teekay Corporation and its subsidiaries (other than us and our subsidiaries) cease to beneficially own shares representing a majority of the total voting power of our outstanding capital stock, stockholders may change the number of directors only by the affirmative vote of not less than 80% of the total voting power of our outstanding capital stock. The board of directors may change the number of directors only by a majority vote of the entire board.
 
Stockholder Meetings
 
Under our bylaws, annual general meetings will be held at a time and place selected by our board of directors. The meetings may be held in or outside of the Marshall Islands. If we fail to hold an annual meeting within 90 days of the designated date, a special meeting in lieu of an annual meeting may be called by stockholders holding not less than 10% of the voting power of all outstanding shares entitled to vote at such meeting. Other than such a meeting in lieu of an annual meeting, special meetings of stockholders may be called only by the chairman of our board of

directors or our chief executive officer, at the direction of our board of directors as set forth in a resolution stating the purpose or purposes thereof approved by a majority of the entire board of directors, or by Teekay Corporation so long as Teekay Corporation and its affiliates (other than us and our subsidiaries) beneficially own at least a majority of the total voting power of our outstanding capital stock. Our board of directors may set a record date between 15 and 60 days before the date of any meeting to determine the stockholders that will be eligible to receive notice of and vote at the meeting.
 
Dissenters’ Rights of Appraisal and Payment
 
Under the Marshall Islands Act, our stockholders have the right to dissent from various corporate actions, including any merger or consolidation or sale of all or substantially all of our assets, and receive payment of the fair value of their shares. In the event of any amendment of our articles of incorporation, a stockholder also has the right to dissent and receive payment for the stockholder’s shares if the amendment alters certain rights in respect of those shares. The dissenting stockholder must follow the procedures set forth in the Marshall Islands Act to receive payment. If we and any dissenting stockholder fail to agree on a price for the shares, the Marshall Islands Act procedures involve, among other things, the institution of proceedings in any appropriate court in any jurisdiction in which our shares are primarily traded on a local or national securities exchange.
 
Stockholders’ Derivative Actions
 
Under the Marshall Islands Act, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of common stock both at the time the derivative action is commenced and at the time of the transaction to which the action relates.
 
Limitations on Director Liability and Indemnification of Directors and Officers
 
The Marshall Islands Act authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties. Our articles of incorporation include a provision that eliminates the personal liability of directors for monetary damages for actions taken as a director to the fullest extent permitted by law.
 
Our articles of incorporation also provide that we must indemnify our directors and officers to the fullest extent permitted by law. We are also expressly authorized to advance certain expenses (including attorneys’ fees and disbursements and court costs) to our directors and offices and to carry directors’ and officers’ insurance providing indemnification for our directors and officers for some liabilities. We believe that these indemnification provisions and insurance are useful to attract and retain qualified directors and officers.
 
The limitation of liability and indemnification provisions in our articles of incorporation may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against our directors and officers pursuant to these indemnification provisions.
 
Our articles of incorporation also renounce in favor of Teekay Corporation business opportunities that may be attractive to both Teekay Corporation and us. This provision effectively limits the fiduciary duties we or our stockholders otherwise may be owed regarding these business opportunities by our directors and officers who also serve as directors or officers of Teekay Corporation or its other affiliates. If Teekay Corporation or its affiliates no longer beneficially own shares representing at least 20% of the total voting power of our outstanding capital stock, and no person who is an officer or director of us is also an officer or director of Teekay Corporation or its other affiliates, then this business opportunity provision of our articles of incorporation will terminate.
 
There is currently no pending litigation or proceeding involving any of our directors, officers or employees for which indemnification is being sought.

Anti-Takeover Effect of Certain Provisions of Our Articles of Incorporation and Bylaws
 
Several provisions of our articles of incorporation and bylaws, which are summarized below, may have anti-takeover effects. These provisions are intended to avoid costly takeover battles, lessen our vulnerability to a hostile change of control and enhance the ability of our board of directors to maximize stockholder value in connection with any unsolicited offer to acquire us. However, these anti-takeover provisions, which are summarized below, could also discourage, delay or prevent (1) the merger or acquisition of us by means of a tender offer, a proxy contest or otherwise that a stockholder may consider in its best interest and (2) the removal of incumbent officers and directors.
 
Dual-Class Structure
 
As discussed above, our Class B common stock has five votes per share, subject to a 49% aggregate Class B common stock voting power maximum, while our Class A common stock has one vote per share. Teekay Corporation controls all of our outstanding Class B common stock, representing 49% of the voting power of our outstanding capital stock, in addition to shares of Class A common stock it controls. Because of our dual-class structure, Teekay Corporation will be able to continue to control all matters submitted to our stockholders for approval even if it and its affiliates come to own significantly less than 50% of the shares of our outstanding common stock. This concentrated control could discourage others from initiating any potential merger, takeover or other change of control transaction that other stockholders may view as beneficial.
 
Blank Check Preferred Stock
 
Under the terms of our articles of incorporation, our board of directors has authority, without any further vote or action by our stockholders, to issue up to 100 million shares of “blank check” preferred stock. Our board could authorize the issuance of preferred stock with voting or conversion rights that could dilute the voting power or rights of the holders of common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of us or the removal of our management and might harm the market price of our Class A common stock. We have no current plans to issue any shares of preferred stock.
 
Election and Removal of Directors
 
Our articles of incorporation prohibit cumulative voting in the election of directors. Our bylaws require parties other than the board of directors to give advance written notice of nominations for the election of directors. These provisions may discourage, delay or prevent the removal of incumbent officers and directors.
 
Our bylaws provide that stockholders are required to give us advance notice of any person they wish to propose for election as a director at an annual general meeting if that person is not proposed by our board of directors. These advance notice provisions provide that the stockholder must have given written notice of such proposal not less than 90 days nor more than 120 days prior to the anniversary date of the immediately preceding annual general meeting. In the event the annual general meeting is called for a date that is not within 30 days before or after such anniversary date, notice by the stockholder must be given not later than 10 days following the earlier of the date on which notice of the annual general meeting was mailed to stockholders or the date on which public disclosure of the date of the annual general meeting was made.
 
Our stockholders may not call special meetings for the purpose of electing directors except in lieu of an annual meeting as discussed above or to replace a director being removed by the stockholders. Our articles of incorporation provide that any director or our entire board of directors may be removed at any time, with or without cause, by the affirmative vote of the holders of a majority of the total voting power of our outstanding capital stock or by directors constituting at least two-thirds of the entire board of directors. However, from and after the date that Teekay Corporation and its affiliates (other than us and our subsidiaries) cease to beneficially own shares representing a majority of the total voting power of our outstanding capital stock, directors may only be removed for cause and only by the affirmative vote of the holders of not less than 80% of the total voting power of our outstanding capital stock.

Limited Actions by Stockholders
 
Our bylaws provide that any action required or permitted to be taken by our stockholders must be effected at an annual or special meeting of stockholders or by the unanimous written consent of our stockholders, provided that if the Marshall Islands Act in the future permits action to be taken by less than unanimous written consent of our stockholders, the holders of voting power sufficient to take such specified action may do so by written consent so long as Teekay Corporation and its affiliates (other than us and our subsidiaries) beneficially own shares representing a majority of the total voting power of our outstanding capital stock. Our bylaws provide that, subject to certain limited exceptions, only (a) our Chairman or Chief Executive Officer, at the direction of the board of directors, or (b) Teekay Corporation, so long as Teekay Corporation and its affiliates (other than us and our subsidiaries) beneficially own at least a majority of the total voting power of our outstanding capital stock, may call special meetings of our stockholders, and the business transacted at the special meeting is limited to the purposes stated in the notice. Accordingly, a stockholder may be prevented from calling a special meeting for stockholder consideration of a proposal over the opposition of our board of directors and stockholder consideration of a proposal may be delayed until the next annual general meeting.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS
 
The following is a discussion of the material U.S. federal income tax considerations that may be relevant to prospective stockholders 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 as to factual matters only, including descriptions of our operations contained herein.
 
This discussion is based upon provisions of the U.S. Internal Revenue Code of 1986, as amended (or the Code) as in effect on the date of this prospectus supplement, existing final and temporary regulations thereunder (or Treasury Regulations), and current administrative rulings and court decisions, all of which are subject to change, possibly with retroactive effect. Changes in these authorities may cause the tax consequences to vary substantially from the consequences described below. Unless the context otherwise requires, references in this section to “we,” “our” or “us” are references to Teekay Tankers Ltd.
 
The following summary does not comment on all aspects of U.S. federal income taxation which may be important to particular stockholders in light of their individual circumstances, such as stockholders subject to special tax rules (e.g., financial institutions, insurance companies, broker-dealers, tax-exempt organizations, or former citizens or long-term residents of the United States) or to persons that will hold the common stock as part of a straddle, hedge, conversion, constructive sale, or other integrated transaction for U.S. federal income tax purposes, partnerships or their partners, or to persons that have a functional currency other than the U.S. dollar, all of whom may be subject to tax rules that differ significantly from those summarized below. If a partnership or other entity taxed as a pass-through entity holds our common stock, the tax treatment of a partner or owner thereof generally will depend upon the status of the partner or owner and upon the activities of the partnership or pass-through entity. If you are a partner in a partnership or owner of a pass-through entity holding our common stock, you should consult your tax advisor.
 
No ruling has been or will be requested from the Internal Revenue Service (or the IRS) regarding any matter affecting us or prospective stockholders. Instead, we will rely on the opinion of Perkins Coie LLP. Unlike a ruling, an opinion of counsel represents only that counsel’s best legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made here may not be sustained by a court if contested by the IRS.
 
This summary does not discuss any U.S. state or local, estate or alternative minimum tax considerations regarding the ownership or disposition of common stock. This summary is written for stockholders that hold their common stock as a “capital asset” under the Code. Each stockholder is urged to consult its tax advisor regarding the U.S. federal, state, local and other tax consequences of the ownership or disposition of common stock.
 
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 a U.S. citizen or resident (as determined for U.S. federal income tax purposes), U.S. corporation or other U.S. entity taxable as a corporation, an estate the income of which is subject to U.S. federal income taxation regardless of its source, or a trust if a court within the United States is able to exercise primary jurisdiction over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust.
 
Distributions
 
Subject to the discussion of passive foreign investment companies (or PFICs) 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 or accumulated earnings and profits, as determined under U.S. federal income tax principles. Distributions in excess of our earnings and profits will be treated first as a nontaxable return of capital to the extent of the U.S. Holder’s tax basis in its common stock on a dollar-for-dollar basis and thereafter as capital gain. U.S. Holders that are corporations generally will not be entitled to claim a dividends received deduction with respect to any distributions they receive from us. Dividends paid with respect to our common stock generally will be treated as “passive


13


Table of Contents

category income” or, in the case of certain types of U.S. Holders, “general category income” for purposes of computing allowable foreign tax credits for U.S. federal income tax purposes.
 
Dividends paid on our common stock to a U.S. Holder who is an individual, trust or estate (or a U.S. Individual Holder) will be treated as “qualified dividend income” that currently is taxable to such U.S. Individual Holder at preferential capital gain tax rates provided that: (i) our common stock is readily tradable on an established securities market in the United States (such as the New York Stock Exchange on which we expect our common stock will be traded); (ii) we are not a PFIC for the taxable year during which the dividend is paid or the immediately preceding taxable year (which we do not believe we are, have been or will be, as discussed below); (iii) the U.S. Individual Holder has owned the common stock for more than 60 days in the 121-day period beginning 60 days before the date on which the common stock become ex-dividend; and (iv) the U.S. Individual Holder is not under an obligation to make related payments with respect to positions in substantially similar or related property. There is no assurance that any dividends paid on our common stock will be eligible for these preferential rates in the hands of a U.S. Individual Holder. Any dividends paid on our common stock not eligible for these preferential rates will be taxed at ordinary graduated tax rates. In the absence of legislation extending the term of the preferential tax rates for qualified dividend income, all dividends received by a taxpayer in tax years beginning on January 1, 2011 or later will be taxed at ordinary graduated tax rates.
 
Special rules may apply to any “extraordinary dividend” paid by us. An extraordinary dividend generally is a dividend with respect to a share of stock if the amount of the dividend equals or exceeds 10.0% of a stockholder’s adjusted basis (or fair market value in certain circumstances) in such stock. If we pay an “extraordinary dividend” on our common stock that is treated as “qualified dividend income,” then any loss derived by a U.S. Individual Holder from the sale or exchange of such common stock will be treated as long-term capital loss to the extent of such dividend.
 
Consequences of Possible PFIC Classification
 
A non-U.S. entity treated as a corporation for U.S. federal income tax purposes will be 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: (i) at least 75.0% of its gross income is “passive” income; or (ii) at least 50.0% of the average value of its assets is attributable to assets that produce passive income or are held for the production of passive income.
 
For purposes of these tests, “passive income” includes dividends, interest, and 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. For purposes of these tests, income derived from the performance of services does not constitute “passive income.” While there are legal uncertainties involved in this determination, our counsel, Perkins Coie LLP, is of the opinion that it is more likely than not that we would not be treated as a PFIC based on certain representations that we have made to them regarding the composition of our assets, the source of our income, and the nature of our activities and other operations following this offering, including:
 
  •  The income derived from our participation in pooling arrangements and from our other time and voyage charters will be greater than 25.0% 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.
 
In addition to these representations, the opinion of Perkins Coie LLP that it is more likely than not that we would not be a PFIC is based principally on the position that at least a majority, if not all, of the gross income we derive from our time and voyage charters (as a participant in one of our pooling arrangements or otherwise) is services income, rather than rental income. There is, however, no direct legal authority under the PFIC rules addressing our method of operation and, therefore no assurance can be given that the IRS will accept this position 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. Moreover, a recent decision of the United States Court of Appeals for the Fifth Circuit in Tidewater Inc. v. United States, No. 08-30268 (5th Cir. Apr. 13, 2009) held that income derived from certain time-chartering


14


Table of Contents

activities should be treated as rental income rather than services income. However, the issues in this case arose under the foreign sales corporation rules of the Code and did not concern the PFIC rules. In addition, the court’s ruling was contrary to the position of the IRS that the time-charter income should be treated as services income. As a result, it is uncertain whether the principles of the Tidewater decision would be applicable to our operations. However, if the principles of the Tidewater decision were applicable to all of our operations, Perkins Coie LLP is of the opinion that we likely would be treated as a PFIC.
 
If we were classified as a PFIC, for any year during which a U.S. Holder owns common stock, such U.S. Holder generally will be subject to special rules (regardless of whether we continue thereafter to be a PFIC) with respect to: (i) any “excess distribution” (generally, any distribution received by a stockholder in a taxable year that is greater than 125.0% of the average annual distributions received by the stockholder in the three preceding taxable years or, if shorter, the stockholder’s holding period for the shares), and (ii) any gain realized upon the sale or other disposition of shares. Under these rules:
 
  •  the excess distribution or gain will be allocated ratably over the stockholder’s holding period;
 
  •  the amount allocated to the current taxable year and any year prior to the first year in which we were a PFIC will be taxed as ordinary income in the current year;
 
  •  the amount allocated to each of the other taxable years in the stockholder’s holding period will be subject to U.S. federal income tax at the highest rate in effect for the applicable class of taxpayer for that year; and
 
  •  an interest charge for the deemed deferral benefit will be imposed with respect to the resulting tax attributable to each such other taxable year.
 
Certain elections that would alter the tax consequences to a U.S. Holder, such as a qualified electing fund election or mark to market election, may be available to a U.S. Holder if we are classified as a PFIC. If we determine that we are or will be a PFIC, we will provide stockholders with information concerning the potential availability of such elections.
 
As described above, current law provides that dividends received by a U.S. Individual Holder from a qualified foreign corporation are subject to U.S. federal income tax at preferential rates through 2010. However, if we are classified as a PFIC for a taxable year in which we pay a dividend or the immediately preceding taxable year, we would not be considered a qualified foreign corporation, and a U.S. Individual Holder receiving such dividends would not be eligible for the reduced rate of U.S. federal income tax.
 
Consequences of Possible Controlled Foreign Corporation Classification
 
If more than 50.0% of either the total combined voting power of our outstanding stock entitled to vote or the total value of all of our outstanding stock were owned, directly, indirectly or constructively, by citizens or residents of the United States, U.S. partnerships or corporations, or U.S. estates or trusts (as defined for U.S. federal income tax purposes), each of which owned, directly, indirectly or constructively, 10.0% or more of the total combined voting power of our outstanding stock entitled to vote (each, a United States Stockholder), we generally would be treated as a controlled foreign corporation (or CFC). United States Stockholders of a CFC are treated as receiving current distributions of their shares of certain income of the CFC (not including, under current law, certain undistributed earnings attributable to shipping income) without regard to any actual distributions and are subject to other burdensome U.S. federal income tax and administrative requirements but generally are not also subject to the requirements generally applicable to owners of a PFIC. Although we are not a CFC as of the date of this Annual Report, U.S. persons purchasing a substantial interest in us should consult their tax advisors about the potential implications of being treated as a United States Stockholder in the event we were to become a CFC in the future.
 
Sale, Exchange or other Disposition of Common Stock
 
Assuming we do not constitute a PFIC for any taxable year, a U.S. Holder generally will recognize taxable 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 will be treated as long-


15


Table of Contents

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, and subject to preferential capital gain tax rates. Such capital gain or loss generally will be treated as U.S. source gain or loss, as applicable, for U.S. foreign tax credit purposes. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations. A disposition or sale of shares by a stockholder who owns, or has owned, 10.0% or more of the total voting power of us may result in a different tax treatment under Section 1248 of the Code. U.S. Holder’s purchasing a substantial interest in us should consult their tax advisors.
 
United States Federal Income Taxation of Non-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
 
Distributions we pay to a Non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax if the Non-U.S. Holder is not engaged in a U.S. trade or business. If the Non-U.S. Holder is engaged in a U.S. trade or business, distributions we pay will be subject to U.S. federal income tax to the extent those distributions constitute income effectively connected with that Non-U.S. Holder’s U.S. trade or business. However, distributions paid to a Non-U.S. Holder who is engaged in a trade or business may be exempt from taxation under an income tax treaty if the income represented thereby is not attributable to a U.S. permanent establishment maintained by the Non-U.S. Holder.
 
Disposition of Common Stock
 
The U.S. federal income taxation of Non-U.S. Holders on any gain resulting from the disposition of our common stock generally is the same as described above regarding distributions. However, individual Non-U.S. Holders may be subject to tax on gain resulting from the disposition of our common stock if they are present in the United States for 183 days or more during the taxable year in which those shares are disposed and meet certain other requirements.
 
Backup Withholding and Information Reporting
 
In general, payments of distributions or the proceeds of a disposition of 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 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 within the United States by certifying their status on IRS Form W-8BEN, W-8ECI or W-8IMY, as applicable.
 
Backup withholding is not an additional tax. Rather, a stockholder generally may obtain a credit for any amount withheld against its liability for U.S. federal income tax (and a refund of any amounts withheld in excess of such liability) by filing a return with the IRS.

NON-UNITED STATES TAX CONSIDERATIONS
 
Marshall Islands Tax Considerations
 
The following discussion is based upon the opinion of Watson, Farley & Williams (New York) 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 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, conduct business 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 Marshall Islands law you will not be subject to Marshall Islands taxation or withholding on distributions. In addition, you will not be subject to Marshall Islands stamp, capital gains or other taxes on the purchase, ownership or disposition of shares of Class A 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 Class A common stock.
 
It is the responsibility of each stockholder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, including the Marshall Islands, of its investment in us. Accordingly, each stockholder is urged to consult its tax counsel or other advisor with regard to those matters. Further, it is the responsibility of each stockholder to file all state, local and non-U.S., as well as U.S. federal, tax returns that may be required of him.

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 U.S. Securities Act of 1933, 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 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 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 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 the over-the-counter market or otherwise. These activities will be described in more detail in the applicable prospectus supplement.
 
Pursuant to a requirement by the Financial Industry Regulatory Authority (or FINRA), the maximum commission or discount to be received by any FINRA member or independent broker/dealer may not be greater than 8% of the gross proceeds received by us for the sale of any securities being offered by this prospectus.
 
In the event that more than 10% of the net proceeds of any offering of securities made under this prospectus will be received by FINRA members participating in the offering or affiliates or associated persons of such FINRA members, the offering will be conducted in accordance with FINRA Rule 5110(h).

SERVICE OF PROCESS AND ENFORCEMENT OF CIVIL LIABILITIES
 
Teekay Tankers Ltd. is incorporated under the laws of the Republic of The Marshall Islands as a 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 or our subsidiaries 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 (New York) LLP to accept service of process on our behalf in any such action.
 
Watson, Farley & Williams (New York) LLP, our counsel as to Marshall Islands law, has advised us that there is uncertainty as to whether the courts of the Republic of The Marshall Islands would (1) 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 (2) 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 the applicable prospectus supplement, the validity of the shares of Class A common stock offered and certain other legal matters with respect to the laws of the Republic of The Marshall Islands will be passed upon for us by our counsel as to Marshall Islands law, Watson, Farley & Williams (New York) LLP. Certain other legal matters will be passed upon for us by Perkins Coie LLP, Portland, Oregon, who may rely upon the opinion of Watson, Farley & Williams (New York) LLP, for all matters of Marshall Islands law. Any underwriter will be advised about other issues relating to any offering by its own legal counsel.
