We may, from time to time, offer to sell in one or more offerings up to an aggregate of $200,000,000 of our common units, preferred units, convertible preferred units, debt securities or convertible debt securities, warrants or any combination of the foregoing. We refer to our common units, preferred units, convertible preferred units, debt securities, convertible debt securities and warrants collectively as the “securities.” The securities we may offer may be convertible into or exercisable or exchangeable for other securities. We may offer the securities separately or together, in separate series or classes and in amounts, at prices and on terms described in one or more supplements to this prospectus.

This prospectus describes some of the general terms that may apply to these securities. Each time we sell securities, the specific terms of the securities to be offered including the amount of securities offered, and any other information relating to a specific offering, will be set forth in an amendment to the registration statement of which this prospectus is a part, or in a supplement to this prospectus, or may be set forth in one or more documents incorporated by reference in this prospectus.

We may offer and sell these securities to or through one or more underwriters, dealers and agents, or directly to purchasers, or through other means, on a continuous or delayed basis. If any underwriters are involved in the sale of any securities offered by this prospectus and any prospectus supplement, their names, and any applicable purchase price, fee, commission or discount arrangement between or among them, will be set forth, or may be calculable from the information set forth, in the applicable prospectus supplement.

You should read this prospectus and any prospectus supplement carefully before you invest in any of our securities. This prospectus may not be used to offer and sell securities unless accompanied by a prospectus supplement.

Our common units are traded on the New York Stock Exchange (or NYSE) under the symbol “TOO.” On December 26, 2017, the last reported sale price of our common units on the NYSE was $2.28 per unit.

Investing in our securities involves a high degree of risk. In addition, limited partnerships are inherently different than corporations. You should carefully consider the section entitled “Forward-Looking Statements” contained on page 2 and each of the factors described under “Risk Factors” beginning on page 4 of this prospectus before you make an investment in our securities.

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

FORWARD-LOOKING STATEMENTS

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

Forward-looking statements reflect management’s current plans, expectations, estimates, assumptions and beliefs concerning future events affecting us. Forward-looking statements involve known and unknown risks and are based upon a number of assumptions and estimates that are inherently subject to significant uncertainties and contingencies, many of which are beyond our control. Actual results could differ materially from those expressed or implied by such forward-looking statements. Important factors that could cause actual results to differ materially include, but are not limited, to those factors discussed under the heading “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” set forth in our Annual Reports on Form 20-F and any Reports on Form 6-K that we incorporate herein by reference, as well as in any prospectus supplement relating to this prospectus and other public filings with the SEC.

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

TEEKAY OFFSHORE PARTNERS L.P.

Teekay Offshore Partners L.P. is an international provider of marine transportation, oil production, storage, long-distance towing and offshore installation and maintenance and safety services to the offshore oil industry, focusing on the deep-water offshore oil regions of the North Sea, Brazil and the East Coast of Canada. We were formed as a Marshall Islands limited partnership in August 2006 by Teekay Corporation (NYSE: TK), a portfolio manager and project developer in the marine midstream market. In September 2017, an affiliate of Brookfield Business Partners L.P. (NYSE: BBU) (TSX: BBU.UN) (or Brookfield) purchased from an affiliate of Teekay Corporation a 49% interest in our general partner and purchased from us common units. We seek to leverage the expertise, relationships and reputations of Teekay Corporation and Brookfield to pursue long-term growth opportunities. Our growth strategy focuses primarily on increasing our fleet of shuttle tankers and floating production, storage and offloading (or FPSO) units under medium to long-term charters while evaluating opportunities to expand into related offshore services segments. Over the long-term, we intend to continue our practice of primarily acquiring vessels as needed for approved projects only after charters for the projects have been awarded to us, rather than ordering vessels on a speculative basis. We have entered into, and may enter into additional joint ventures and partnerships with companies that may provide increased access to new opportunities, and we may engage in vessel or business acquisitions. We are structured as a master limited partnership. As of September 25, 2017, the public held a total of 26.7% of our outstanding common units, Brookfield TK TOLP L.P. (or Brookfield TOLP), an affiliate of Brookfield, held 59.5% of our outstanding common units and Brookfield TK TOGP L.P. (or Brookfield TOGP), an affiliate of Brookfield, held a 49% interest in our general partner, and an affiliate of Teekay Corporation held the remaining 13.8% of our outstanding common units and a 51% interest in our general partner.

Our operations are conducted through, and our operating assets are owned by, our subsidiaries. Our general partner, Teekay Offshore GP L.L.C., a Marshall Islands limited liability company, has an economic interest in us and manages our operations and activities.

Our general partner does not receive any management fee or other compensation in connection with its management of our business, but it is entitled to be reimbursed for all direct and indirect expenses incurred on our behalf. Pursuant to services agreements between us and our subsidiaries, on the one hand, and subsidiaries of Teekay Corporation, on the other hand, the Teekay Corporation subsidiaries provide to us certain administrative services and to our subsidiaries certain strategic, business development, advisory, ship management, technical and administrative services.

We are a limited partnership organized under the laws of the Republic of The Marshall Islands. 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 website address is www.teekayoffshore.com. The information contained in our website is not part of this prospectus.

RISK FACTORS

An investment in our securities involves a high degree of risk. Before investing in our securities, you should carefully consider all of the information included or incorporated by reference into this prospectus. Although many of our business risks are comparable to those of a corporation engaged in a similar business, limited partner interests are inherently different from the capital stock of a corporation. When evaluating an investment in any of our securities, you should carefully consider the following risk factor 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, and if applicable, in our Reports on Form 6-K, filed with or furnished to the SEC, which are incorporated by reference into this prospectus, and information included in any applicable prospectus supplement. Each of the risks described in these sections and documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a loss of your investment. Additional risks and uncertainties known or not known to us or that we deem immaterial may also impair our business, financial condition, results of operations and prospects.

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

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

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

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

DESCRIPTION OF EQUITY SECURITIES

The following descriptions of our common units and Series A Preferred Units and Series B Preferred Units do not purport to be complete and are subject to, and qualified in their entirety by reference to, the provisions of our fifth amended and restated partnership agreement (or the partnership agreement), which is incorporated by reference into this prospectus supplement, and sets forth the terms of our common units, Series A Preferred Units and our Series B Preferred Units. Although the partnership agreement refers to Series C, C-1 and D preferred units, none of those units remains issued and outstanding; accordingly, the following descriptions do not discuss such series of preferred units. A copy of the partnership agreement may be obtained from us as described under “Where You Can Find Additional Information.” We may also offer additional common units, preferred units or convertible preferred units, in one or more series, the terms of which may differ substantially from the terms of the Series A Preferred Units and Series B Preferred Units described herein. We will set forth in an accompanying prospectus supplement a description of the preferred units or convertible preferred units that may be offered under this prospectus. The terms of the offering of securities, including the public offering price and any net proceeds to us, will be contained in the accompanying prospectus supplement and other offering material relating to such offering.

Common Units

Our common units represent limited partner interests in us. The holders of units are entitled to participate in partnership distributions and exercise the rights and privileges available to limited partners under our partnership agreement. For a description of the rights of holders of our common units to receive partnership distributions, please read “Cash Distributions.” For a description of certain other rights and privileges of holders of our common units under our partnership agreement, please read “The Partnership Agreement.”

Number of Units

As of December 20, 2017, there were 410,045,210 of our common units outstanding. The common units represent an aggregate 99.24% limited partner interest and the general partner interest represents a 0.76% general partner interest in us. Our general partner’s 0.76% interest in us will be reduced if we issue certain additional partnership securities and our general partner does not elect to invest in such securities to maintain its 0.76% general partner interest. Please read “The Partnership Agreement—Issuance of Additional Securities.”

Voting

On any matter in which the holders of our common units are entitled to vote as a class, such holders will be entitled to one vote per unit. For a description of matters on which the common units are entitled to vote, please read “The Partnership Agreement.”

Distributions

The holders of our common units are entitled to receive, to the extent permitted by law, such distributions as may from time to time be declared by our general partner’s board of directors. Upon any liquidation, dissolution or winding up of our affairs, whether voluntary or involuntary, the holders of our common units are entitled to receive distributions of our assets, after we have satisfied or made provision for our debts and other obligations and for payment to the holders any class or series of limited partner interests (including the Series A Preferred Units and the Series B Preferred Units) having preferential rights to receive distributions of our assets.

Exchange Listing

Our common units are listed on the New York Stock Exchange, where they trade under the symbol “TOO.”

Transfer Agent and Registrar

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

Preferred Units

In April 2013, we issued 6,000,000 of our Series A Preferred Units, which are all outstanding as of the date hereof. In April 2015, we issued 5,000,000 of our Series B Preferred Units, which are all outstanding as of the date hereof. We may, without notice to or consent of the holders of the then-outstanding Series A Preferred Units or Series B Preferred Units, authorize and issue additional Series A Preferred Units, Series B Preferred Units and Junior Securities (as defined in the partnership agreement). We may authorize and issue Parity Securities and Senior Securities (as defined in the partnership agreement), subject to any rights of the holders of the then-outstanding Series A Preferred Units and Series B Preferred Units described under “—Voting Rights.”

The Series A Preferred Units and Series B Preferred Units entitle the holders thereof to receive cumulative cash distributions when, as and if declared by our general partner’s board of directors out of legally available funds for such purpose. Subject to the matters described under “—Liquidation Rights,” each Series A Preferred Unit and Series B Preferred Unit generally has a fixed liquidation preference of $25.00 per unit plus an amount equal to accumulated and unpaid distributions thereon to the date fixed for payment, whether or not declared. Please read “—Liquidation Rights.”

The Series A Preferred Units and Series B Preferred Units represent perpetual equity interests in us and, unlike our indebtedness, do not give rise to a claim for payment of a principal amount at a particular date. As such, the Series A Preferred Units and Series B Preferred Units rank junior to all of our indebtedness and other liabilities with respect to assets available to satisfy claims against us.

All the Series A Preferred Units and all the Series B Preferred Units, respectively, are represented by a single certificate issued to the Depository Trust Company (or the Securities Depository) and registered in the name of its nominee and, so long as a Securities Depository has been appointed and is serving, no person acquiring Series A Preferred Units or Series B Preferred Units will be entitled to receive a certificate representing such units unless applicable law otherwise requires or the Securities Depository resigns or is no longer eligible to act as such and a successor is not appointed. Please read “—Book-Entry System.”

The Series A Preferred Units and the Series B Preferred Units are not convertible into common units or other of our securities, and the Series A Preferred Units and the Series B Preferred do not have exchange rights and are not entitled or subject to any preemptive or similar rights. The Series A Preferred Units and Series B Preferred Units are not subject to mandatory redemption or to any sinking fund requirements. The Series A Preferred Units and Series B Preferred Units are subject to redemption, in whole or in part, at our option commencing on April 30, 2018 and April 20, 2020, respectively. Please read “—Redemption.”

Computershare serves as the paying agent (or the Paying Agent), and the registrar and transfer agent (or the Registrar and Transfer Agent) for the Series A Preferred Units and Series B Preferred Units. The address of the Paying Agent is 250 Royall Street, Canton MA 02021.

Ranking

The Series A Preferred Units and Series B Preferred Units, with respect to anticipated quarterly distributions and distributions upon the liquidation, winding-up and dissolution of our affairs, rank:

7

Under the partnership agreement, we may issue Junior Securities from time to time in one or more series without the consent of the holders of the Series A Preferred Units or Series B Preferred Units. Our general partner’s board of directors has the authority to determine the preferences, powers, qualifications, limitations, restrictions and special or relative rights or privileges, if any, of any such series before the issuance of any units of that series. Our general partner’s board of directors will also determine the number of units constituting each series of securities. Our ability to issue additional Parity Securities in certain circumstances or Senior Securities is limited as described under “—Voting Rights.”

Liquidation Rights

The holders of outstanding Series A Preferred Units and Series B Preferred Units will be entitled, in the event of any liquidation, dissolution or winding up of our affairs, whether voluntary or involuntary, to receive the liquidation preference of $25.00 per unit in cash plus an amount equal to accumulated and unpaid distributions thereon to the date fixed for payment of such amount (whether or not declared), and no more, before any distribution will be made to the holders of our common units or any other Junior Securities. A consolidation or merger of us with or into any other entity, individually or in a series of transactions, will not be deemed a liquidation, dissolution or winding up of our affairs for this purpose. In the event that our assets available for distribution to holders of the outstanding Series A Preferred Units, Series B Preferred Units and any other Parity Securities are insufficient to permit payment of all required amounts, our assets then remaining will be distributed among the Series A Preferred Units, Series B Preferred Units and any Parity Securities, as applicable, ratably on the basis of their relative aggregate liquidation preferences. After payment of all required amounts to the holders of the outstanding Series A Preferred Units and Series B Preferred Units and other Parity Securities, our remaining assets and funds will be distributed among the holders of the common units and any other Junior Securities then outstanding according to their respective rights.

Voting Rights

The Series A Preferred Units and Series B Preferred Units have no voting rights except as set forth below or as otherwise provided by Republic of the Marshall Islands law. In the event that six quarterly distributions, whether consecutive or not, payable on the Series A Preferred Units or Series B Preferred Units are in arrears, the holders of the Series A Preferred Units and Series B Preferred Units will have the right, voting as a class together with holders of any other Parity Securities upon which like voting rights have been conferred and are exercisable, to elect one member of our general partner’s board of directors, and the size of our general partner’s board of directors will be increased as needed to accommodate such change (unless the holders of Series A Preferred Units, Series B Preferred Units and Parity Securities upon which like voting rights have been conferred, voting as a class, have previously elected a member of our general partner’s board of directors, and such director continues then to serve on the board of directors). Distributions payable on the Series A Preferred Units or Series B Preferred Units, as applicable, will be considered to be in arrears for any quarterly period for which full cumulative distributions through the most recent Distribution Payment Date (as defined below) have not been paid on all outstanding Series A Preferred Units or Series B Preferred Units, as applicable. The right of such holders of Series A Preferred Units and Series B Preferred Units to elect a member of our general partner’s board of directors will continue until such time as all distributions accumulated and in arrears on the Series A Preferred Units or Series B Preferred Units, as applicable, have been paid in full, or funds for the payment thereof have been declared and set aside, at which time such right will terminate, subject to revesting in the event of each and every subsequent failure to pay six quarterly distributions as described above. Upon any termination of the right of the holders of the Series A Preferred Units, Series B Preferred Units and any other Parity Securities to vote as a class for such director, the term of office of such director then in office elected by such holders voting as a class will terminate immediately. Any directors elected by the holders of the Series A Preferred Units, Series B Preferred Units and any other Parity Securities shall each be entitled to one vote per director on any matter before our general partner’s board of directors.

Unless we have received the affirmative vote or consent of the holders of at least two-thirds of the outstanding Series A Preferred Units, voting as a single class, we may not adopt any amendment to our

8

partnership agreement that has a material adverse effect on the existing terms of the Series A Preferred Units. Unless we have received the affirmative vote or consent of the holders of at least two-thirds of the outstanding Series B Preferred Units, voting as a single class, we may not adopt any amendment to our partnership agreement that has a material adverse effect on the existing terms of the Series B Preferred Units.

In addition, unless we have received the affirmative vote or consent of the holders of at least two-thirds of the outstanding Series A Preferred Units and Series B Preferred Units, voting as a class together with holders of any other Parity Securities upon which like voting rights have been conferred and are exercisable, we may not:

On any matter described above in which the holders of the Series A Preferred Units or Series B Preferred Units are entitled to vote as a class, such holders will be entitled to one vote per unit. The Series A Preferred Units and Series B Preferred Units held by us or any of our subsidiaries or affiliates will not be entitled to vote.

Series A Preferred Units and Series B Preferred Units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and his nominee provides otherwise.

Distributions

General

Holders of Series A Preferred Units and Series B Preferred Units are entitled to receive, when, as and if declared by our general partner’s board of directors out of legally available funds for such purpose, cumulative cash distributions.

Distribution Rate

Distributions on the Series A Preferred Units accrue at a rate of 7.25% per annum per $25.00 stated liquidation preference per Series A Preferred Unit. Distributions on the Series B Preferred Units accrue at a rate of 8.50% per annum per $25.00 stated liquidation preference per Series B Preferred Unit.

Distribution Payment Dates

The “Distribution Payment Dates” for the Series A Preferred Units and Series B Preferred Units are each February 15, May 15, August 15 and November 15. Distributions accumulate in each distribution period from and including the preceding Distribution Payment Date to but excluding the applicable Distribution Payment Date for such distribution period, and distributions accrue on accumulated distributions at the applicable distribution rate. If any Distribution Payment Date otherwise would fall on a day that is not a Business Day, declared distributions will be paid on the immediately succeeding Business Day without the accumulation of additional distributions. Distributions on the Series A Preferred Units and Series B Preferred Units are payable based on a 360-day year consisting of twelve 30-day months. “Business Day” means a day on which The New York Stock Exchange is open for trading and which is not a Saturday, a Sunday or other day on which banks in New York City are authorized or required by law to close.

Payment of Distributions

Not later than the close of business, New York City time, on each Distribution Payment Date, we will pay those quarterly distributions, if any, on the Series A Preferred Units and Series B Preferred Units that have been

9

declared by our general partner’s board of directors to the holders of such units as such holders’ names appear on our unit transfer books maintained by the Registrar and Transfer Agent on the applicable Record Date. The applicable record date (or Record Date) is the fifth Business Day immediately preceding the applicable Distribution Payment Date, except that in the case of payments of distributions in arrears, the Record Date with respect to a Distribution Payment Date will be such date as may be designated by our general partner’s board of directors in accordance with our partnership agreement, as amended.

So long as the Series A Preferred Units and Series B Preferred Units are held of record by the nominee of the Securities Depository, declared distributions will be paid to the Securities Depository in same-day funds on each Distribution Payment Date. The Securities Depository will credit accounts of its participants in accordance with the Securities Depository’s normal procedures. The participants will be responsible for holding or disbursing such payments to beneficial owners of the Series A Preferred Units and Series B Preferred Units in accordance with the instructions of such beneficial owners.

No distribution may be declared or paid or set apart for payment on any Junior Securities (other than a distribution payable solely in units of Junior Securities) unless full cumulative distributions have been or contemporaneously are being paid or provided for on all outstanding Series A Preferred Units, Series B Preferred Units and any Parity Securities through the most recent respective distribution payment dates. Accumulated distributions in arrears for any past distribution period may be declared by our general partner’s board of directors and paid on any date fixed by our general partner’s board of directors, whether or not a Distribution Payment Date, to holders of the Series A Preferred Units and Series B Preferred Units on the Record Date for such payment, which may not be more than 60 days, nor less than 15 days, before such payment date. Subject to the next succeeding sentence, if all accumulated distributions in arrears on all outstanding Series A Preferred Units, Series B Preferred Units and any Parity Securities have not been declared and paid, or sufficient funds for the payment thereof have not been set apart, payment of accumulated distributions in arrears will be made in order of their respective distribution payment dates, commencing with the earliest. If less than all distributions payable with respect to all Series A Preferred Units, Series B Preferred Units and any Parity Securities are paid, any partial payment will be made pro rata with respect to the Series A Preferred Units, Series B Preferred Units and any Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series A Preferred Units, Series B Preferred Units and other such Parity Securities at such time. Holders of the Series A Preferred Units or Series B Preferred Units will not be entitled to any distribution, whether payable in cash, property or units, in excess of full cumulative distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid distributions as described under “—Distributions—Distribution Rate,” no interest or sum of money in lieu of interest will be payable in respect of any distribution payment which may be in arrears on the Series A Preferred Units or Series B Preferred Units.

Redemption

Optional Redemption

Commencing on April 30, 2018, we may redeem, at our option, in whole or in part, the Series A Preferred Units at a redemption price in cash equal to $25.00 per unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared. Commencing on April 20, 2020, we may redeem, at our option, in whole or in part, the Series B Preferred Units at a redemption price in cash equal to $25.00 per unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared. Any such optional redemption shall be effected only out of funds legally available for such purpose. We may undertake multiple partial redemptions.

Redemption Procedures

We will give notice of any redemption by mail, postage prepaid, not less than 30 days and not more than 60 days before the scheduled date of redemption, to the holders of any units to be redeemed as such holders’

10

names appear on our unit transfer books maintained by the Registrar and Transfer Agent at the address of such holders shown therein. Such notice shall state: (1) the redemption date, (2) the number of Series A Preferred Units or Series B Preferred Units, as applicable, to be redeemed and, if less than all outstanding Series A Preferred Units or Series B Preferred Units are to be redeemed, the number (and the identification) of units to be redeemed from such holder, (3) the redemption price, (4) the place where the Series A Preferred Units or Series B Preferred Units are to be redeemed and shall be presented and surrendered for payment of the redemption price therefor and (5) that distributions on the units to be redeemed will cease to accumulate from and after such redemption date.

If fewer than all of the outstanding Series A Preferred Units or Series B Preferred Units, as applicable, are to be redeemed, the number of units to be redeemed will be determined by us, and such units will be redeemed by such method of selection as the Securities Depository shall determine, pro rata or by lot, with adjustments to avoid redemption of fractional units. So long as all Series A Preferred Units or Series B Preferred Units, as applicable, are held of record by the nominee of the Securities Depository, we will give notice, or cause notice to be given, to the Securities Depository of the number of Series A Preferred Units or Series B Preferred Units, as applicable, to be redeemed, and the Securities Depository will determine the number of Series A Preferred Units or Series B Preferred Units to be redeemed from the account of each of its participants holding such units in its participant account. Thereafter, each participant will select the number of units to be redeemed from each beneficial owner for whom it acts (including the participant, to the extent it holds Series A Preferred Units or Series B Preferred Units, as applicable, for its own account). A participant may determine to redeem Series A Preferred Units or Series B Preferred Units, as applicable, from some beneficial owners (including the participant itself) without redeeming Series A Preferred Units or Series B Preferred Units from the accounts of other beneficial owners.

So long as the Series A Preferred Units or Series B Preferred Units, as applicable, are held of record by the nominee of the Securities Depository, the redemption price will be paid by the Paying Agent to the Securities Depository on the redemption date. The Securities Depository’s normal procedures provide for it to distribute the amount of the redemption price in same-day funds to its participants who, in turn, are expected to distribute such funds to the persons for whom they are acting as agent.

If we give or cause to be given a notice of redemption, then we will deposit with the Paying Agent funds sufficient to redeem the Series A Preferred Units or Series B Preferred Units, as applicable, as to which notice has been given by the close of business, New York City time, no later than the Business Day immediately preceding the date fixed for redemption, and will give the Paying Agent irrevocable instructions and authority to pay the redemption price to the holder or holders thereof upon surrender or deemed surrender (which will occur automatically if the certificate representing such units is issued in the name of the Securities Depository or its nominee) of the certificates therefor. If notice of redemption shall have been given, then from and after the date fixed for redemption, unless we default in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the notice, all distributions on such units will cease to accumulate and all rights of holders of such units as our unitholders will cease, except the right to receive the redemption price, including an amount equal to accumulated and unpaid distributions through the date fixed for redemption, whether or not declared. We will be entitled to receive from the Paying Agent the interest income, if any, earned on such funds deposited with the Paying Agent (to the extent that such interest income is not required to pay the redemption price of the units to be redeemed), and the holders of any units so redeemed will have no claim to any such interest income. Any funds deposited with the Paying Agent hereunder by us for any reason, including, but not limited to, redemption of Series A Preferred Units or Series B Preferred Units, that remain unclaimed or unpaid after two years after the applicable redemption date or other payment date, shall be, to the extent permitted by law, repaid to us upon our written request, after which repayment the holders of the Series A Preferred Units or Series B Preferred Units entitled to such redemption or other payment shall have recourse only to us.

If only a portion of the Series A Preferred Units or Series B Preferred Units, as applicable, represented by a certificate has been called for redemption, upon surrender of the certificate to the Paying Agent (which will occur

11

automatically if the certificate representing such units is registered in the name of the Securities Depository or its nominee), the Paying Agent will issue to the holder of such units a new certificate (or adjust the applicable book-entry account) representing the number of Series A Preferred Units or Series B Preferred Units represented by the surrendered certificate that have not been called for redemption.

Notwithstanding any notice of redemption, there will be no redemption of any Series A Preferred Units or Series B Preferred Units called for redemption until funds sufficient to pay the full redemption price of such units, including all accumulated and unpaid distributions to the date of redemption, whether or not declared, have been deposited by us with the Paying Agent.

We and our affiliates may from time to time purchase the Series A Preferred Units and Series B Preferred Units, subject to compliance with all applicable securities and other laws.

Notwithstanding the foregoing, in the event that full cumulative distributions on the Series A Preferred Units, Series B Preferred Units and any Parity Securities have not been paid or declared and set apart for payment, we may not repurchase, redeem or otherwise acquire, in whole or in part, any Series A Preferred Units, Series B Preferred Units or Parity Securities except pursuant to a purchase or exchange offer made on the same terms to all holders of Series A Preferred Units, Series B Preferred Units and any Parity Securities. Common units and any other Junior Securities may not be redeemed, repurchased or otherwise acquired unless full cumulative distributions on the Series A Preferred Units, Series B Preferred Units and any Parity Securities for all prior and the then-ending distribution periods have been paid or declared and set apart for payment.

No Sinking Fund

Neither the Series A Preferred Units nor the Series B Preferred Units have the benefit of any sinking fund.

No Fiduciary Duty

We, our general partner, and our general partner’s officers and directors, do not owe any fiduciary duties to holders of the Series A Preferred Units or Series B Preferred Units other than a contractual duty of good faith and fair dealing pursuant to our partnership agreement.

Book-Entry System

All Series A Preferred Units and all Series B Preferred Units, respectively, are represented by a single certificate issued to the Securities Depository (and its successors or assigns or any other securities depository selected by us), and registered in the name of its nominee (initially, Cede & Co.). No holder of Series A Preferred Units or Series B Preferred Units is entitled to receive a certificate evidencing such units unless otherwise required by law or the Securities Depository gives notice of its intention to resign or is no longer eligible to act as such and we have not selected a substitute Securities Depository within 60 calendar days thereafter. Payments and communications made by us to holders of the Series A Preferred Units or Series B Preferred Units will be duly made by making payments to, and communicating with, the Securities Depository. Accordingly, unless certificates are available to holders of Series A Preferred Units or Series B Preferred Units, each purchaser of Series A Preferred Units and Series B Preferred Units must rely on (1) the procedures of the Securities Depository and its participants to receive distributions, any redemption price, liquidation preference and notices, and to direct the exercise of any voting or nominating rights, with respect to such Series A Preferred Units and Series B Preferred Units and (2) the records of the Securities Depository and its participants to evidence its ownership of such Series A Preferred Units and Series B Preferred Units.

So long as the Securities Depository (or its nominee) is the sole holder of the Series A Preferred Units or Series B Preferred Units, as applicable, no beneficial holder of the Series A Preferred Units or Series B Preferred Units will be deemed to be a unitholder of us. The Depository Trust Company, the initial Securities Depository,

12

is a New York-chartered limited purpose trust company that performs services for its participants, some of whom (and/or their representatives) own The Depository Trust Company. The Securities Depository maintains lists of its participants and will maintain the positions (i.e., ownership interests) held by its participants in the Series A Preferred Units and Series B Preferred Units, whether as a holder of the Series A Preferred Units or Series B Preferred Units for its own account or as a nominee for another holder of the Series A Preferred Units or Series B Preferred Units.

THE PARTNERSHIP AGREEMENT

The following is a summary of certain material terms of our partnership agreement. For additional information, we refer you to our partnership agreement, which is filed as an exhibit to the registration statement of which this prospectus is a part. Although the partnership agreement refers to Series C, C-1 and D preferred units, none of those units remains issued and outstanding; accordingly, the following description does not discuss such series of preferred units.

Organization and Duration

We were formed on August 31, 2006 under the Marshall Islands Limited Partnership Act (or the Marshall Islands Act) and have perpetual existence.

Purpose

Our partnership agreement provides that we may directly or indirectly engage in business activities approved by our general partner, including owning interests in subsidiaries through which we conduct operations. Although our general partner has the ability to cause us to engage in activities other than the marine transportation, processing and storage of crude oil, our general partner has no current plans to do so and may decline to do so free of any fiduciary duty or obligation whatsoever to us or our limited partners, including any duty to act in good faith or in the best interests of us or our limited partners. Our general partner owes a contractual duty of good faith and fair dealing to the holders of Series A Preferred Units and Series B Preferred Units pursuant to our partnership agreement. Our general partner is authorized in general to perform all acts it determines to be necessary or appropriate to carry out our purposes and to conduct our business.

Power of Attorney

Each limited partner, and each person who acquires any limited partner interest from another limited partner, grants to our general partner and, if appointed, a liquidator, a power of attorney to, among other things, execute and file documents required for our qualification, continuance or dissolution. The power of attorney also grants our general partner the authority to amend, and to make consents and waivers under, our partnership agreement.

Capital Contributions

No holder of common units, Series A Preferred Units or Series B Preferred Units is obligated to make additional capital contributions, except as described below under “—Limited Liability.”

Voting Rights

The following matters require the unitholder or common unitholder vote specified below. Matters requiring the approval of a “common unit majority” require the approval of a majority of our common units.

14

In voting their common units or any Series A Preferred Units or Series B Preferred Units they may hold, our general partner and its affiliates (including for certainty Teekay Corporation and Brookfield) have no fiduciary duty or obligation whatsoever to us or our unitholders, including any duty to act in good faith or in the best interests of us and our unitholders.

Holders of the Series A Preferred Units and Series B Preferred Units have no voting rights, other than the limited voting rights described in “Description of Equity Securities—Preferred Units—Voting Rights.”

Limited Liability

Assuming that a limited partner does not participate in the control of our business within the meaning of the Marshall Islands Act, the limited partner’s liability under the Marshall Islands Act will be limited, subject to possible exceptions, to the amount of capital the limited partner is obligated to contribute to us for the limited partner’s units plus the limited partner’s share of any undistributed profits and assets. If it were determined, however, that the right, or exercise of the right, by our limited partners as a group:

15

constituted that a limited partner “participates in the control” of our business for the purposes of the Marshall Islands Act, then our limited partners could be held personally liable for our obligations under the laws of the Republic of the Marshall Islands, to the same extent as our general partner. This liability would extend to persons who transact business with us and reasonably believe that the limited partner is a general partner. Neither our partnership agreement nor the Marshall Islands Act specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner. While this does not mean that a limited partner could not seek legal recourse, we know of no precedent for this type of a claim in the Republic of the Marshall Islands case law.

Under the Marshall Islands Act, a limited partnership may not make a distribution to a partner if, at the time of the distribution, after giving effect to the distribution, all liabilities of the limited partnership, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of the limited partnership, would exceed the fair value of the assets of the limited partnership, except that the fair value of property that is subject to a liability for which the recourse of creditors is limited shall be included in the assets of the limited partnership only to the extent that the fair value of that property exceeds that liability. The Marshall Islands Act provides that a limited partner who receives a distribution and knew at the time of the distribution that the distribution was in violation of the Marshall Islands Act shall be liable to the limited partnership for the amount of the distribution for three years. Under the Marshall Islands Act, an assignee of partnership interests who becomes a limited partner of a limited partnership is liable for the obligations of the assignor to make contributions to the partnership, except the assignee is not obligated for liabilities unknown to the assignee at the time the assignee became a limited partner and that could not be ascertained from the partnership agreement.

Maintenance of limited liability may require compliance with legal requirements in the jurisdictions in which our subsidiaries conduct business, which may include qualifying to do business in those jurisdictions.

Limitations on the liability of limited partners for the obligations of a limited partner have not been clearly established in many jurisdictions. If, by virtue of our ownership or control of operating subsidiaries or otherwise, it were determined that we were conducting business in any jurisdiction without compliance with the applicable limited partnership or limited liability company statute, or that the right or exercise of the right by our limited partners as a group to remove or replace our general partner, to approve some amendments to our partnership agreement, or to take other action under our partnership agreement constituted “participation in the control” of our business for purposes of the statutes of any relevant jurisdiction, then our limited partners could be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We intend to operate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of our limited partners.

Issuance of Additional Securities

Our partnership agreement authorizes us to issue an unlimited number of additional partnership securities and rights to buy partnership securities for the consideration and on the terms and conditions determined by our general partner, without the approval of our unitholders, other than the limited approval rights of the holders of the Series A Preferred Units and Series B Preferred Units described above under “Description of Equity Securities—Preferred Units—Voting Rights.”

We may fund acquisitions through the issuance of additional common units or other equity securities. Holders of any additional common units, Series A Preferred Units or Series B Preferred Units we may issue will be entitled to share equally with the then-existing holders of our common units, Series A Preferred Units or Series B Preferred Units, as applicable, in distributions. In addition, the issuance of additional common units or other equity securities interests may dilute the value of the interests of the then-existing holders of our common units in our net assets.

16

In accordance with the Republic of the Marshall Islands law and the provisions of our partnership agreement, we may also issue additional partnership securities that, as determined by our general partner, have special voting or other rights to which our common units, Series A Preferred Units or Series B Preferred Units are not entitled.

Upon issuance of certain additional partnership securities (including our common units, but excluding our Series A Preferred Units and Series B Preferred Units), our general partner will have the right, but not the obligation, to make additional capital contributions to the extent necessary to maintain its general partner interest in us at the same percentage level as before the issuance. Our general partner’s 0.76% interest in us will thus be reduced if we issue certain additional partnership securities and our general partner does not elect to maintain its 0.76% general partner interest. Our general partner’s interest does not entitle it to receive any portion of distributions made in respect of the Series A Preferred Units and Series B Preferred Units and our general partner’s interest will not be affected by the issuance of any additional Series A Preferred Units or Series B Preferred Units. Our general partner and its affiliates also have the right, which it may from time to time assign in whole or in part to any of its affiliates, to purchase common units or other equity securities whenever, and on the same terms that, we issue those securities to persons other than our general partner and its affiliates, to the extent necessary to maintain its and its affiliates’ percentage interest in us, including its interest represented by common units, that existed immediately prior to each issuance. Other holders of common units will not have similar preemptive rights to acquire additional common units or other partnership securities.

Amendment of Our Partnership Agreement

General

Amendments to our partnership agreement may be proposed only by or with the consent of our general partner. However, our general partner has no duty or obligation to propose any amendment and may decline to do so free of any fiduciary duty or obligation whatsoever to us or our limited partners, including any duty to act in good faith or in the best interests of us or our limited partners. In order to adopt a proposed amendment, other than the amendments discussed below, our general partner must seek written approval of the holders of the number of common units required to approve the amendment or call a meeting of our common unitholders to consider and vote upon the proposed amendment. In addition, holders of Series A Preferred Units and Series B Preferred Units must approve certain amendments as described above under “Description of Equity Securities—Preferred Units—Voting Rights.” Except as we describe below, or for amendments that require Series A Preferred Unit or Series B Preferred Unit approval or approval of Series A Preferred Units and Series B Preferred Units voting together as a class with all other classes or series of parity securities upon which like voting rights have been conferred and are exercisable, an amendment must be approved by a common unit majority.

Prohibited Amendments

No amendment may be made that would:

17

The provision of our partnership agreement preventing the amendments having the effects described in clauses (1) through (5) above can be amended upon the approval of the holders of at least 90% of the outstanding units voting together as a single class (including units owned by our general partner and its affiliates).

No Unitholder Approval

Our general partner may generally make amendments to our partnership agreement without the approval of any limited partner to reflect:

In addition, our general partner may make amendments to our partnership agreement without the approval of any limited partner (subject to the limited approval rights of holders of Series A Preferred Units and Series B Preferred Units described above under “Description of Equity Securities—Preferred Units—Voting Rights”) if our general partner determines that those amendments:

18

Opinion of Counsel and Unitholder Approval

Our general partner will not be required to obtain an opinion of counsel that an amendment will not result in a loss of limited liability to our limited partners if one of the amendments described above under “—No Unitholder Approval” should occur. No other amendments to our partnership agreement will become effective without the approval of holders of at least 90% of our outstanding units voting as a single class unless we obtain an opinion of counsel to the effect that the amendment will not affect the limited liability under applicable law of any of our limited partners.

In addition to the above restrictions, any amendment that would have a material adverse effect on the rights or privileges of any type or class or series of units (other than Series A Preferred Units or Series B Preferred Units) in relation to other classes or series of units will require the approval of at least a majority of the type or class or series of units so affected; provided, however, that any amendment that would have a material adverse effect on the existing terms of the Series A Preferred Units or Series B Preferred Units will require the approval of at least two-thirds of the outstanding Series A Preferred Units or Series B Preferred Units, respectively. Any amendment that reduces the voting percentage required to take any action must be approved by the affirmative vote of limited partners whose aggregate outstanding units constitute not less than the voting requirement sought to be reduced.

Merger, Sale, or Other Disposition of Assets

A merger or consolidation of us requires the consent of our general partner, in addition to the approval of a common unit majority. However, our general partner will have no duty or obligation to consent to any merger or consolidation and may decline to do so free of any fiduciary duty or obligation whatsoever to us or the limited partners, including any duty to act in good faith or in the best interests of us or the limited partners; provided, however, that our general partner owes a contractual duty of good faith and fair dealing to holders of the Series A Preferred Units and Series B Preferred Units pursuant to our partnership agreement. In addition, our partnership agreement generally prohibits our general partner, without common unitholder approval, from causing us to sell, exchange, or otherwise dispose of all or substantially all of our assets. Our general partner may, however, mortgage, pledge, hypothecate, or grant a security interest in all or substantially all of our assets without unitholder approval.

If conditions specified in our partnership agreement are satisfied, our general partner may convert us or any of our subsidiaries into a new limited liability entity or merge us or any of our subsidiaries into, or convey some or all of our assets to, a newly formed entity if the sole purpose of that merger or conveyance is to effect a mere change in our legal form into another limited liability entity.

Our unitholders are not entitled to dissenters’ rights of appraisal under our partnership agreement or applicable law in the event of a conversion, merger or consolidation, a sale of substantially all of our assets, or any other transaction or event.

Termination and Dissolution

We will continue as a limited partnership until terminated under our partnership agreement. We will dissolve upon:

19

Upon a dissolution under clause (4), the holders of a common unit majority may also elect, within specific time limitations, to continue our business on the same terms and conditions described in our partnership agreement by appointing as general partner an entity approved by the holders of a common unit majority, subject to our receipt of an opinion of counsel to the effect that the action would not result in the loss of limited liability of any limited partner.

Liquidation and Distribution of Proceeds

Upon our dissolution, unless we are continued as a new limited partnership, the liquidator authorized to wind up our affairs will, acting with all of the powers of our general partner that are necessary or appropriate, liquidate our assets and apply the proceeds of the liquidation as described in our partnership agreement. The liquidation rights of holders of Series A Preferred Units, Series B Preferred Units and Parity Securities are described under “Description of Equity Securities—Liquidation Rights.” The liquidator may defer liquidation or distribution of our assets for a reasonable period or distribute assets to partners in kind if it determines that a sale would be impractical or would cause undue loss to our partners.

Withdrawal or Removal of Our General Partner

Our general partner may withdraw as general partner without first obtaining approval of any common unitholder by giving 90 days’ written notice, and that withdrawal will not constitute a violation of our partnership agreement. In addition, our partnership agreement permits our general partner in some instances to sell or otherwise transfer all of its general partner interest in us without the approval of the common unitholders. Please read “—Transfer of General Partner Interest” and “—Transfer of Incentive Distribution Rights.”

Upon withdrawal of our general partner under any circumstances, other than as a result of a transfer by our general partner of all or a part of its general partner interest in us, the holders of a common unit majority may select a successor to that withdrawing general partner. If a successor is not elected, we will be dissolved, wound up and liquidated, unless within a specified period of time after that withdrawal, the holders of a common unit majority agree in writing to continue our business and to appoint a successor general partner. Please read “—Termination and Dissolution.”

Our general partner may not be removed unless that removal is approved by the vote of the holders of not less than 66 2/3% of our outstanding units, including units held by our general partner and its affiliates, and we receive an opinion of counsel regarding limited liability. Any removal of our general partner is also subject to the approval of a successor general partner by the vote of the holders of a majority of our outstanding common units, including common units held by our general partner and its affiliates. The ownership of more than 33 1/3% of our outstanding units by our general partner and its affiliates would give them the practical ability to prevent our general partner’s removal.

Our partnership agreement also provides that if our general partner is removed as our general partner under circumstances where cause does not exist and units held by our general partner and its affiliates are not voted in favor of that removal, our general partner will have the right to convert its general partner interest and its incentive distribution rights into common units or to receive cash in exchange for those interests based on the fair market value of the interests at the time.

20

In the event of removal of our general partner under circumstances where cause exists or withdrawal of our general partner where that withdrawal violates our partnership agreement, a successor general partner will have the option to purchase the general partner interest and incentive distribution rights of the departing general partner for a cash payment equal to the fair market value of those interests. Under all other circumstances where our general partner withdraws or is removed by our limited partners, the departing general partner will have the option to require the successor general partner to purchase the general partner interest of the departing general partner and its incentive distribution rights for their fair market value. In each case, this fair market value will be determined by agreement between the departing general partner and the successor general partner. If no agreement is reached, an independent investment banking firm or other independent expert selected by the departing general partner and the successor general partner will determine the fair market value. Or, if the departing general partner and the successor general partner cannot agree upon an expert, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.

If the option described above is not exercised by either the departing general partner or the successor general partner, the departing general partner’s general partner interest and its incentive distribution rights will automatically convert into common units equal to the fair market value of those interests as determined by an investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

In addition, we will be required to reimburse the departing general partner for all amounts due the departing general partner, including, without limitation, any employee-related liabilities, including severance liabilities, incurred for the termination of any employees employed by the departing general partner or its affiliates for our benefit.

Transfer of General Partner Interest

Our general partner and its affiliates may at any time transfer units to one or more persons, without unitholder approval. As a condition of this transfer, the transferee must, among other things, assume the rights and duties of our general partner, agree to be bound by the provisions of our partnership agreement and furnish an opinion of counsel regarding limited liability.

Transfer of Ownership Interests in General Partner

At any time, members of our general partner may sell or transfer all or part of their membership interests in our general partner to an affiliate or a third party without the approval of our unitholders.

Transfer of Incentive Distribution Rights

Our incentive distribution rights may be transferred to one or more persons, without unitholder approval. As a condition of this transfer, the transferee must agree to be bound by the provisions of our partnership agreement.

Transfer of Common Units, Series A Preferred Units and Series B Preferred Units

By transfer of common units, Series A Preferred Units or Series B Preferred Units in accordance with our partnership agreement, each transferee of common units, Series A Preferred Units or Series B Preferred Units automatically is admitted as a limited partner with respect to the common units, Series A Preferred Units or Series B Preferred Units transferred when such transfer and admission is reflected in our books and records. Our general partner will cause any transfers to be recorded on our books and records no less frequently than quarterly. Each transferee automatically is deemed to:

21

We are entitled to treat the nominee holder of a common unit, Series A Preferred Unit or Series B Preferred Unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely to those that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.

Common units, Series A Preferred Units and Series B Preferred Units are securities and are transferable according to the laws governing transfer of securities. In addition to other rights acquired upon transfer, the transferor gives the transferee the right to become a limited partner in our partnership for the transferred common units.

Until a common unit, Series A Preferred Unit or Series B Preferred Unit has been transferred on our books, we and our transfer agent may treat the record holder of the unit as the absolute owner of such unit for all purposes, except as otherwise required by law or stock exchange regulations.

Change of Management Provisions

Our partnership agreement contains specific provisions that are intended to discourage a person or group from attempting to remove Teekay Offshore GP L.L.C. as our general partner or otherwise change management. If any person or group other than our general partner and its affiliates acquires beneficial ownership of 20% or more of our partnership securities of any class or series then outstanding, that person or group will lose voting rights on all of its partnership securities. This loss of voting rights does not apply to the Series A Preferred Units or Series B Preferred Units or to any person or group that acquires the partnership securities from our general partner or its affiliates and any transferees of that person or group approved by our general partner or to any person or group who acquires the partnership securities with the prior approval of the board of directors of our general partner.

Our partnership agreement also provides that if our general partner is removed under circumstances where cause does not exist and units held by our general partner and its affiliates are not voted in favor of that removal, our general partner will have the right to convert its general partner interest and its incentive distribution rights into common units or to receive cash in exchange for those interests.

Call Right

If at any time our general partner and its affiliates hold more than 80% of the then-issued and outstanding limited partner interests of any class or series, except for the Series A Preferred Units and Series B Preferred Units, our general partner will have the right, which it may assign in whole or in part to any of its affiliates or to us, to acquire all, but not less than all, of the remaining limited partner interests of the class or series held by unaffiliated persons as of a record date to be selected by our general partner, on at least 10 but not more than 60 days’ notice. The purchase price in this event is the greater of (x) the average of the daily closing prices of the limited partner interests of such class or series over the 20 trading days preceding the date three days before notice of exercise of the call right is first mailed and (y) the highest price paid by our general partner or any of its affiliates for limited partner interests of such class or series during the 90-day period preceding the date such notice is first mailed.

As a result of our general partner’s right to purchase outstanding limited partner interests, a holder of limited partner interests (except for the Series A Preferred Units and Series B Preferred Units) may have the holder’s limited partner interests purchased at an undesirable time or price.

22

Meetings; Voting

Unlike the holders of common stock in a corporation, the holders of our common units have only limited voting rights on matters affecting our business. They have no right to elect our general partner (who manages our operations and activities) or the directors of our general partner, on an annual or other continuing basis. On those matters that are submitted to a vote of common unitholders, each record holder of a common unit may vote according to the holder’s percentage interest in us, although additional limited partner interests having special voting rights could be issued.

Holders of the Series A Preferred Units and Series B Preferred Units generally have no voting rights. However, holders of Series A Preferred Units and Series B Preferred Units have limited voting rights as described above under “Description of Equity Securities—Preferred Units—Voting Rights.”

Except as described below regarding a person or group owning 20% or more of any class or series of limited partner interest then outstanding, limited partners as of the record date will be entitled to notice of, and to vote at, any meetings of our limited partners and to act upon matters for which approvals by the holders of such class or series of limited partner interests may be solicited.

Any action that is required or permitted to be taken by our unitholders, or any applicable class or series thereof, may be taken either at a meeting of the applicable unitholders or without a meeting if consents in writing describing the action so taken are signed by holders of the number of units necessary to authorize or take that action at a meeting. Meetings of our unitholders may be called by our general partner or by unitholders owning at least 20% of the outstanding units of the class or series for which a meeting is proposed. Unitholders may vote either in person or by proxy at meetings. The holders of a majority of the outstanding units of the class, classes or series for which a meeting has been called, represented in person or by proxy, will constitute a quorum unless any action by the unitholders requires approval by holders of a greater percentage of the units, in which case the quorum will be the greater percentage.

If at any time any person or group, other than our general partner and its affiliates, or a direct or subsequently approved transferee of our general partner or its affiliates or a transferee approved by the board of directors of our general partner, acquires, in the aggregate, beneficial ownership of 20% or more of our partnership securities of any class or series then outstanding, that person or group will lose voting rights on all of its partnership interests, except for the Series A Preferred Units and Series B Preferred Units, and such partnership interests may not be voted on any matter and will not be considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes, determining the presence of a quorum, or for other similar purposes. Common units, Series A Preferred Units and Series B Preferred Units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and the beneficial owner’s nominee provides otherwise.

Any notice, demand, request report, or proxy material required or permitted to be given or made to record holders of common units, Series A Preferred Units or Series B Preferred Units under our partnership agreement will be delivered to the record holder by us or by our transfer agent.

Status as Limited Partner

Except as described above under “—Limited Liability,” our common units, Series A Preferred Units and Series B Preferred Units will be fully paid, and our unitholders will not be required to make additional contributions. By transfer of common units, Series A Preferred Units or Series B Preferred Units in accordance with our partnership agreement, each transferee of common units, Series A Preferred Units and Series B Preferred Units shall be admitted as a limited partner with respect to the common units, Series A Preferred Units or Series B Preferred Units transferred when such transfer and admission is reflected in our books and records.

23

Indemnification

Under our partnership agreement, in most circumstances, we will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages or similar events:

Any indemnification under these provisions will only be out of our assets. Unless it otherwise agrees, our general partner will not be personally liable for, or have any obligation to contribute or lend funds or assets to us to enable us to effectuate, indemnification.

We are authorized to purchase (or to reimburse our general partner for the costs of) insurance against liabilities asserted against and expenses incurred by our general partner, its affiliates and such other persons as the general partner may determine and described in the paragraph above, whether or not it would have the power to indemnify such person against such liabilities under the provisions described in the paragraphs above. Our general partner has purchased insurance covering its officers and directors against liabilities asserted and expenses incurred in connection with their activities as officers and directors of the general partner or any of its direct or indirect subsidiaries.

Reimbursement of Expenses

Our partnership agreement requires us to reimburse our general partner for all direct and indirect expenses it incurs or payments it makes on our behalf and all other expenses allocable to us or otherwise incurred by our general partner in connection with operating our business. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf, and expenses allocated to our general partner by its affiliates. Our general partner is entitled to determine the expenses that are allocable to us.

Books and Reports

Our general partner is required to keep appropriate books of our business at our principal offices. The books will be maintained for both tax and financial reporting purposes on an accrual basis. For tax and fiscal reporting purposes, our fiscal year is the calendar year.

We intend to furnish or make available to record holders of our common units, Series A Preferred Units and Series B Preferred Units, within 120 days after the close of each fiscal year, an annual report containing audited financial statements and a report on those financial statements by our independent chartered accountants. Except for our fourth quarter, we also intend to furnish or make available summary financial information within 90 days after the close of each quarter.

24

Right to Inspect Our Books and Records

Our partnership agreement provides that a limited partner can, for a purpose reasonably related to the limited partner’s interest as a limited partner, upon reasonable demand and at the limited partner’s own expense, have furnished to the limited partner:

Our general partner may, and intends to, keep confidential from the limited partners’ trade secrets or other information the disclosure of which our general partner believes in good faith is not in our best interests or that we are required by law or by agreements with third parties to keep confidential.

Registration Rights

Under our partnership agreement, we have agreed to register for resale under the U.S. Securities Act of 1933, as amended (or the Securities Act), and applicable state securities laws any common units or other partnership securities proposed to be sold by our general partner or any of its affiliates or their assignees if an exemption from the registration requirements is not otherwise available or advisable. These registration rights continue for two years following any withdrawal or removal of Teekay Offshore GP L.L.C. as our general partner. We are obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commissions.

In connection with Brookfield’s investment in us in September 2017 and related transactions, we, Brookfield TOLP and Teekay Corporation entered into a registration rights agreement relating to the registration under the Securities Act of certain of our common units and warrants (or the Registration Rights Agreement). During the period the Registration Rights Agreement is in effect, we have agreed with Brookfield and Teekay Corporation to suspend the registration rights granted to our general partner and its affiliates under our partnership agreement, which are described above. The Registration Rights Agreement provides each of Brookfield TOLP and Teekay Corporation with the right to demand that we file, prior to September 25, 2018, a shelf registration statement with respect to (a) our common units beneficially owned by Brookfield TOLP and its affiliates or Teekay Corporation and its affiliates as of September 25, 2017, including those common units issued to Brookfield TOLP and to an affiliate of Teekay Corporation on such date and (b) our common units issuable upon the exercise of warrants we issued to Brookfield TOLP and to an affiliate of Teekay Corporation in connection with their respective purchases of common units on September 25, 2017 (collectively, the Registrable Securities). The Registration Rights Agreement also provides Brookfield TOLP and Teekay Corporation the right to demand that we register the Registrable Securities in an underwritten offering, on or after September 25, 2018, as well as the right to include the Registrable Securities in any registration statement filed by us in connection with a public offering of our common units or securities convertible into, or exchangeable for, common units, subject to customary exceptions and limitations. The Registration Rights Agreement provides that we will pay all registration expenses other than underwriting discounts and commissions (which will be paid by the holder of the securities being registered), but including the reasonable fees and expenses of any counsel on behalf of the holders of the Registrable Securities.

25

Conflicts of Interest

Conflicts of interest exist and may arise in the future as a result of the relationships between our general partner and its affiliates, including Teekay Corporation and Brookfield, on the one hand, and us and our unaffiliated limited partners, on the other hand. The directors and officers of our general partner, Teekay Offshore GP L.L.C., have certain fiduciary duties to manage our general partner in a manner beneficial to its owners, Teekay Corporation and Brookfield TOGP. At the same time, our general partner has a fiduciary duty to manage us in a manner beneficial to us and our common unitholders. Teekay Corporation and Brookfield TOGP have the authority to appoint our general partner’s directors, who in turn appoint our general partner’s officers. Under our partnership agreement, we, our general partner and our general partner’s officers and directors will not owe any fiduciary duties to holders of the Series A Preferred Units and Series B Preferred Units other than a contractual duty of good faith and fair dealing pursuant to our partnership agreement.

Our partnership affairs are governed by our partnership agreement and the Marshall Islands Act. The provisions of the Marshall Islands Act resemble provisions of the limited partnership laws of a number of states in the United States, most notably Delaware. We are not aware of any material difference in unitholder rights between the Marshall Islands Act and the Delaware Revised Uniform Limited Partnership Act. The Marshall Islands Act also provides that, for non-resident limited partnerships such us, it is to be applied and construed to make the laws of the Republic of the Marshall Islands, with respect to the subject matter of the Marshall Islands Act, uniform with the laws of the State of Delaware and, so long as it does not conflict with the Marshall Island Act or decisions of certain Republic of the Marshall Islands courts, the non-statutory law (or case law) of the courts of the State of Delaware is adopted as the law of the Republic of the Marshall Islands. There have been, however, few, if any, court cases in the Republic of the Marshall Islands interpreting the Marshall Islands Act, in contrast to Delaware, which has a fairly well-developed body of case law interpreting its limited partnership statute. Accordingly, we cannot predict whether Republic of the Marshall Islands courts would reach the same conclusions as courts in Delaware. For example, the rights of our unitholders and fiduciary responsibilities of our general partner under Republic of the Marshall Islands law are not as clearly established as under judicial precedent in existence in Delaware. Due to the less developed nature of Republic of the Marshall Islands law, our public unitholders may have more difficulty in protecting their interests in the face of actions by our general partner or controlling unitholders than would unitholders of a limited partnership organized in the United States.

Whenever a conflict arises between our general partner or its affiliates, on the one hand, and us or any other partner, on the other, our general partner will resolve that conflict. Our partnership agreement contains provisions that modify and restrict our general partner’s fiduciary duties to our unitholders under Republic of the Marshall Islands law. Our partnership agreement also restricts the remedies available to unitholders for actions taken by our general partner that, without those limitations, might constitute breaches of fiduciary duties.

Our general partner will not be in breach of its obligations under the partnership agreement or its duties to us or the common unitholders if the resolution of the conflict is:

26

Our general partner may, but is not required to, seek the approval of such resolution from the conflicts committee of the board of directors of our general partner or from the limited partners. If our general partner does not seek approval from the conflicts committee, and the board of directors of our general partner determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in the third and fourth bullet points above, then it will be presumed that, in making its decision, the board of directors, including the board members affected by the conflict, acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. Unless the resolution of a conflict is specifically provided for in our partnership agreement, our general partner or the conflicts committee may consider any factors it determines in good faith to consider when resolving a conflict. When our partnership agreement requires someone to act in good faith, it requires that person to reasonably believe that the person is acting in the best interests of the partnership, unless the context otherwise requires. The definition of good faith specified above does not apply to the contractual duty of good faith and fair dealing we owe to holders of Series A Preferred Units and Series B Preferred Units.

Conflicts of interest could arise in the situations described below, among others.

Actions taken by our general partner may affect the amount of cash available for distribution to unitholders.

The amount of cash that is available for distribution to unitholders is affected by decisions of our general partner regarding such matters as:

In addition, borrowings by us and our affiliates do not constitute a breach of any duty owed by our general partner to our limited partners, including borrowings that have the purpose or effect of enabling our general partner or its affiliates to receive distributions on the incentive distribution rights.

For example, in the event we have not generated sufficient cash from our operations to pay the minimum quarterly distribution on our common units, our partnership agreement permits us to borrow funds, which would enable us to make this distribution on all outstanding units.

Our partnership agreement provides that we and our subsidiaries may borrow funds from our general partner and its affiliates. Our general partner and its affiliates may not borrow funds from us or our operating subsidiaries.

Neither our partnership agreement nor any other agreement requires Teekay Corporation or Brookfield to pursue a business strategy that favors us or utilizes our assets or dictates what markets to pursue or grow. Teekay Corporation’s and Brookfield’s directors and officers have a fiduciary duty to make these decisions in the best interests of the shareholders of Teekay Corporation and Brookfield, which may be contrary to our interests.

Because directors of our general partner are also directors, officers or employees of Teekay Corporation or Brookfield or their respective affiliates, such directors have fiduciary duties to Teekay Corporation and Brookfield that may cause them to pursue business strategies that disproportionately benefit Teekay Corporation or Brookfield or which otherwise are not in the best interests of us or our unitholders.

27

Our general partner is allowed to take into account the interests of parties other than us, such as Teekay Corporation and Brookfield, in resolving conflicts of interest.

Our partnership agreement contains provisions that restrict the standards to which our general partner would otherwise be held by Republic of the Marshall Islands law. For example, our partnership agreement permits our general partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner. This entitles our general partner to consider only the interests and factors that it desires, and it has no duty or obligation to give any consideration to any interest of or factors affecting us, our affiliates or any limited partner. Decisions made by our general partner in its individual capacity are made by its owners, Teekay Corporation and Brookfield TOGP, and not by the board of directors of our general partner. Examples include the exercise of the general partner’s limited call right, its voting rights with respect to the units it owns, its registration rights and its determination whether to consent to any merger or consolidation involving us.

We reimburse our general partner and its affiliates for expenses.

We reimburse our general partner and its affiliates for costs incurred in managing and operating us, including costs incurred in rendering support services to us. Our partnership agreement provides that our general partner determine in good faith the expenses that are allocable to us.

Our general partner has limited its liability regarding our obligations.

Our general partner has limited its liability under contractual arrangements so that the other party has recourse only to our assets and not against our general partner or its assets or any affiliate of our general partner or its assets. Our partnership agreement provides that any action taken by our general partner to limit its or our liability is not a breach of our general partner’s fiduciary duties owed to common unitholders or a breach of our general partner’s contractual duty of good faith and fair dealing to holders of the Series A Preferred Units or Series B Preferred Units, even if we could have obtained terms that are more favorable without the limitation on liability.

Common unitholders and Series A Preferred Units and Series B Preferred Unitholders have no right to enforce obligations of our general partner and its affiliates under agreements with us.

Any agreements between us, on the one hand, and our general partner and its affiliates, on the other, do not and will not grant to the holders of our common units, Series A Preferred Units or Series B Preferred Units, separate and apart from us, the right to enforce the obligations of our general partner and its affiliates in our favor.

Contracts between us, on the one hand, and our general partner and its affiliates, on the other, are not the result of arms’-length negotiations.

Neither our partnership agreement nor any of the other agreements, contracts and arrangements between us and our general partner and its affiliates are or will be the result of arms’-length negotiations. Our partnership agreement generally provides that any affiliated transaction, such as an agreement, contract or arrangement between us and our general partner and its affiliates, not involving a vote of common unitholders and that is not approved by the conflicts committee of the board of directors of our general partner must be:

Our general partner may also enter into additional contractual arrangements with any of its affiliates on our behalf, and our general partner will determine, in good faith, the terms of any of these transactions.

28

Except in limited circumstances, our general partner has the power and authority to conduct our business without limited partner approval.

Under our partnership agreement, our general partner has full power and authority to do all things (other than those items that require limited partner approval or with respect to which our general partner has sought conflicts committee approval) on such terms as it determines to be necessary or appropriate to conduct our business including, among others, the following:

Please read “—Meetings; Voting” above and “Description of Equity Securities—Preferred Units—Voting Rights” above for information regarding the voting rights of unitholders.

Limited partner interests, except for the Series A Preferred Units and Series B Preferred Units, are subject to our general partner’s call right.

Our general partner may exercise its right to call and purchase limited partner interests, except for the Series A Preferred Units and Series B Preferred Units, as provided in our partnership agreement or assign this right to one of its affiliates or to us. Our general partner may use its own discretion, free of fiduciary duty restrictions, in determining whether to exercise this right. As a result, a limited partner may have limited partner interests purchased by the general partner at an undesirable time or price. Please read “—Call Right” above.

29

We may choose not to retain separate counsel for ourselves or for the holders of limited partner interests.

The attorneys, independent accountants and others who perform services for us have been retained by our general partner. Attorneys, independent accountants and others who perform services for us are selected by our general partner or the conflicts committee and may perform services for our general partner and its affiliates. We may retain separate counsel for ourselves or the holders of our common units, Series A Preferred Units or the Series B Preferred Units in the event of a conflict of interest between our general partner and its affiliates, on the one hand, and us or the holders of common units, Series A Preferred Units or the Series B Preferred Units, on the other, depending on the nature of the conflict. We do not intend to do so in most cases.

Our general partner’s affiliates, including Teekay Corporation and Brookfield, may compete with us.

Our partnership agreement provides that our general partner is restricted from engaging in any business activities other than acting as our general partner and those activities incidental to its ownership of interests in us. In addition, our partnership agreement provides that our general partner, for so long as it is general partner of our partnership, will cause its affiliates not to engage in, by acquisition or otherwise, certain businesses or activities described in an omnibus agreement to which we, Teekay Corporation and other affiliates are parties. Similarly, under the omnibus agreement, Teekay Corporation has agreed and has caused its affiliates to agree, for so long as Teekay Corporation controls our partnership, not to engage in certain business or activities relating to the marine transportation and storage services provided to the offshore oil industry. Except as provided in our partnership agreement and the omnibus agreement, affiliates of our general partner, including Teekay Corporation and Brookfield, are not prohibited from engaging in other businesses or activities, including those that might be in direct competition with us.

Fiduciary Duties

Our general partner is accountable to us and our common unitholders as a fiduciary. Our general partner owes no fiduciary duty to holders of the Series A Preferred Units or Series B Preferred Units other than a contractual duty of good faith and fair dealing pursuant to our partnership agreement. Fiduciary duties owed to our unitholders by our general partner are prescribed by law and our partnership agreement. The Marshall Islands Act provides that Republic of the Marshall Islands partnerships may, in their partnership agreements, restrict or expand the fiduciary duties owed by the general partner to the limited partners and the partnership.

Our partnership agreement contains various provisions restricting the fiduciary duties that might otherwise be owed by our general partner. We have adopted these provisions to allow our general partner to take into account the interests of other parties in addition to our interests when resolving conflicts of interest. We believe this is appropriate and necessary because the board of directors of our general partner has fiduciary duties to manage our general partner in a manner beneficial both to its owners, Teekay Corporation and Brookfield TOGP, as well as to holders of our common units. These modifications disadvantage the limited partners because they restrict the rights and remedies that would otherwise be available to unitholders for actions that, without those limitations, might constitute breaches of fiduciary duty, as described below. The following is a summary of:

30

31

Under our partnership agreement, we must indemnify our general partner and its officers and directors to the fullest extent permitted by law, against liabilities, costs and expenses incurred by our general partner or these other persons. We must provide this indemnification unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that these persons acted in bad faith or engaged in fraud, willful misconduct or gross negligence. We also must provide this indemnification for criminal proceedings when our general partner or these other persons acted with no reasonable cause to believe that their conduct was unlawful.

Thus, our general partner could be indemnified for its negligent acts if it met the requirements set forth above. To the extent that these provisions purport to include indemnification for liabilities arising under the Securities Act, in the opinion of the SEC such indemnification is contrary to public policy and therefore unenforceable. Please read “—Indemnification” above.

32

CASH DISTRIBUTIONS

Distribution of Available Cash

General

Within approximately 45 days after the end of each quarter, we distribute all of our available cash to common unitholders of record on the applicable record date.

Available Cash

Available cash generally means, for each fiscal quarter, all cash on hand at the end of the quarter (including our proportionate share of cash on hand of certain subsidiaries we do not wholly own):

Series A Preferred Units

Our Series A Preferred Units rank senior to our common units as to the payment of distributions and amounts payable upon liquidation, dissolution or winding up and have a liquidation preference of $25.00 per unit, and rank pari passu with our existing Series B Preferred Units. Our Series A Preferred Units are entitled to cumulative distributions from the date of original issue, with distributions being calculated at an annual rate of 7.25% on the stated liquidation preference and payable quarterly in arrears on the 15th day of February, May, August and November of each year, when, as and if declared by the board of directors of our general partner. At any time on or after April 30, 2018, the Series A Preferred Units may be redeemed, in whole or in part, at a redemption price of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared. No distribution may be declared or paid or set apart for payment on any common units (other than a distribution payable solely in common units) unless full cumulative distributions have been or contemporaneously are being paid or provided for on all outstanding Series A Preferred Units and Series B Preferred Units through the most recent distribution payment date for the Series A Preferred Units and Series B Preferred Units. For additional information about our Series A Preferred Units, please read “Description of Equity Securities—Preferred Units.”

Series B Preferred Units

Our Series B Preferred Units rank senior to our common units as to the payment of distributions and amounts payable upon liquidation, dissolution or winding up and have a liquidation preference of $25.00 per unit, and rank pari passu with our existing Series A Preferred Units. Our Series B Preferred Units are entitled to

33

cumulative distributions from the date of original issue, with distributions being calculated at an annual rate of 8.50% on the stated liquidation preference and payable quarterly in arrears on the 15th day of February, May, August and November of each year, when, as and if declared by the board of directors of our general partner. At any time on or after April 20, 2020, the Series B Preferred Units may be redeemed, in whole or in part, at a redemption price of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared. No distribution may be declared or paid or set apart for payment on any common units (other than a distribution payable solely in common units) unless full cumulative distributions have been or contemporaneously are being paid or provided for on all outstanding Series B Preferred Units and Series A Preferred Units through the most recent distribution payment date for the Series B Preferred Units and Series A Preferred Units. For additional information about our Series A Preferred Units, please read “Description of Equity Securities—Preferred Units.”

Minimum Quarterly Distribution

Our general partner has the authority to determine the amount of our available cash for any quarter. This determination, as well as all determinations made by our general partner, must be made in good faith. There is no guarantee that we will pay the minimum quarterly distribution of $0.35 per unit or any other amount on our common units in any quarter, and we will be prohibited from making any distributions to our common unitholders if it would cause an event of default, or an event of default is existing, under our credit facilities, or if full cumulative distributions have not been paid or are not contemporaneously being paid or provided for on all outstanding Series A and Series B Preferred Units through the most recent distribution payment date for the Series A and Series B Preferred Units.

Operating Surplus and Capital Surplus

General

All cash distributed to common unitholders is characterized as either “operating surplus” or “capital surplus.” We treat distributions of available cash from operating surplus differently than distributions of available cash from capital surplus.

Definition of Operating Surplus

Operating surplus, for any period, generally means:

34

If a working capital borrowing, which increases operating surplus, is not repaid during the 12-month period following the borrowing, it is deemed repaid at the end of such period, thus decreasing operating surplus at such time. When such working capital borrowing is in fact repaid, it is not treated as a reduction in operating surplus because operating surplus has been previously reduced by the deemed repayment.

As described above, operating surplus includes a provision that enables us, if we choose, to distribute as operating surplus up to $15 million of cash we have received or will receive from non-operating sources since the time of our initial public offering, such as asset sales, issuances of securities and long-term borrowings, that would otherwise be distributed as capital surplus. In addition, the effect of including, as described above, certain cash distributions on equity securities or interest payments on debt in operating surplus is to increase operating surplus by the amount of any such cash distributions or interest payments. As a result, we may distribute as operating surplus up to the amount of any such cash distributions or interest payments of cash we receive from non-operating sources.

Capital Expenditures

For purposes of determining operating surplus, maintenance capital expenditures are those capital expenditures required to maintain over the long term the operating capacity of or the revenue generated by capital assets, and expansion capital expenditures are those capital expenditures that increase the operating capacity of or the revenue generated by capital assets. To the extent, however, that capital expenditures associated with acquiring or conversion of an existing or new vessel increase the revenues or the operating capacity of our fleet, those capital expenditures would be classified as expansion capital expenditures.

Investment capital expenditures are those capital expenditures that are neither maintenance capital expenditures nor expansion capital expenditures. Investment capital expenditures largely consist of capital expenditures made for investment purposes.

Examples of investment capital expenditures include traditional capital expenditures for investment purposes, such as purchases of securities, as well as other capital expenditures that might be made in lieu of such traditional investment capital expenditures, such as the acquisition of a capital asset for investment purposes.

Examples of maintenance capital expenditures include capital expenditures associated with drydocking a vessel or acquiring or converting an existing or a new vessel to the extent such expenditures are incurred to

35

maintain the operating capacity of or the revenue generated by our fleet. Maintenance capital expenditures also include interest (and related fees) on debt incurred and distributions on equity issued to finance the conversion or construction of a replacement vessel and paid during the conversion or construction period, which we define as the period beginning on the date of entry into a binding conversion or construction contract and ending on the earlier of the date that the replacement vessel commences commercial service or the date that the replacement vessel is abandoned or disposed of. Debt incurred to pay or equity issued to fund conversion or construction period interest payments, and distributions on such equity, are also considered maintenance capital expenditures.

Because maintenance capital expenditures can be very large and vary significantly in timing, the amount of our actual maintenance capital expenditures may differ substantially from period to period, which could cause similar fluctuations in the amounts of operating surplus, adjusted operating surplus, and available cash for distribution to our common unitholders if we subtracted actual maintenance capital expenditures from operating surplus each quarter. Accordingly, to eliminate the effect on operating surplus of these fluctuations, our partnership agreement requires that an amount equal to an estimate of the average quarterly maintenance capital expenditures necessary to maintain the operating capacity of or the revenue generated by our capital assets over the long term be subtracted from operating surplus each quarter, as opposed to the actual amounts spent. The amount of estimated maintenance capital expenditures deducted from operating surplus is subject to review and change by the board of directors of our general partner at least once a year, provided that any change must be approved by the board’s conflicts committee. The estimate is made at least annually and whenever an event occurs that is likely to result in a material adjustment to the amount of our maintenance capital expenditures, such as a major acquisition or the introduction of new governmental regulations that will affect our fleet. For purposes of calculating operating surplus, any adjustment to this estimate is prospective only.

The use of estimated maintenance capital expenditures in calculating operating surplus has the following effects:

Definition of Capital Surplus

Capital surplus generally is generated only by:

Characterization of Common Unit Cash Distributions

We treat all available cash distributed on our common units as coming from operating surplus until the sum of all available cash distributed since we began operations equals the operating surplus as of the most recent date of determination of available cash. We treat any amount distributed on our common units in excess of operating surplus, regardless of its source, as capital surplus. As described above, operating surplus does not reflect actual cash on hand that is available for distribution to our common unitholders. For example, it includes a provision that enables us, if we choose, to distribute as operating surplus up to $15 million of cash we have received or will

36

receive from non-operating sources since the time of our initial public offering, such as asset sales, issuances of securities and long-term borrowings that would otherwise be distributed as capital surplus. We do not anticipate that we will make any distributions on our common units from capital surplus.

Distributions of Available Cash From Operating Surplus

We make distributions of available cash from operating surplus in the following manner:

The percentage interests set forth above assume that our general partner maintains its 0.76% general partner interest and has not transferred the incentive distribution rights and that we do not issue additional classes of equity securities.

Incentive Distribution Rights

Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution for our common units and the target distribution levels have been achieved. Our general partner currently holds all of the outstanding incentive distribution rights, but may transfer these rights separately from its general partner interest without unitholder approval. Any transfer by our general partner of the incentive distribution rights would not change the percentage allocations of quarterly distributions with respect to such rights.

If for any quarter we have distributed available cash from operating surplus to the common unitholders in an amount equal to the minimum quarterly distribution, then we distribute any additional available cash from operating surplus for that quarter among the common unitholders and our general partner in the following manner:

The percentage interests set forth above assume that our general partner maintains its 0.76% general partner interest and has not transferred the incentive distribution rights and that we do not issue additional classes of equity securities.

Percentage Allocations of Available Cash From Operating Surplus

The following table illustrates the percentage allocations of available cash from operating surplus between the common unitholders and our general partner up to the various target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of the common unitholders and

37

our general partner in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Target Amount,” until available cash from operating surplus we distribute reaches the next target distribution level, if any. The percentage interests shown for the common unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests shown for our general partner include its 0.76% general partner interest and assume our general partner has contributed any capital necessary to maintain its 0.76% general partner interest and has not transferred the incentive distribution rights.

Distributions From Capital Surplus

How Distributions From Capital Surplus Are Made

We make distributions of available cash from capital surplus, if any, in the following manner:

The preceding paragraph is based on the assumption that our general partner maintains its 0.76% general partner interest and that we do not issue additional classes of equity securities.

Effect of a Distribution From Capital Surplus

Our partnership agreement treats a distribution of capital surplus on our common units as the repayment of the initial unit price from our initial public offering on December 19, 2006, which is a return of capital. That initial public offering price less any distributions of capital surplus per unit is referred to as the “unrecovered initial unit price.” Each time a distribution of capital surplus on our common units is made, the minimum quarterly distribution for the common units and the target distribution levels will be reduced in the same proportion as the corresponding reduction in the unrecovered initial unit price. Because distributions of capital surplus will reduce the minimum quarterly distribution, after any of these distributions are made, it may be easier for our general partner to receive incentive distributions. However, any distribution of capital surplus on our common units before the unrecovered initial unit price is reduced to zero cannot be applied to the payment of the minimum quarterly distribution.

Once we distribute capital surplus on a common unit issued in our initial public offering in an amount equal to the initial unit price, we will reduce the minimum quarterly distribution and the target distribution levels for our common units to zero. We will then make all future distributions on our common units from operating surplus, with 51.24% being paid to the holders of common units and 48.76% to our general partner. The percentage interests shown for our general partner include its 0.76% general partner interest and assume the general partner maintains its 0.76% general partner interest and has not transferred the incentive distribution rights.

38

Adjustment to the Minimum Quarterly Distribution and Target Distribution Levels

In addition to adjusting the minimum quarterly distribution and target distribution levels for our common units to reflect a distribution of capital surplus, if we combine our common units into fewer units or subdivide our common units into a greater number of units, we will proportionately adjust:

For example, if a two-for-one split of the common units should occur, the minimum quarterly distribution, the target distribution levels and the unrecovered initial unit price would each be reduced to 50% of its initial level. We will not make any adjustment by reason of the issuance of additional common units for cash or property.

Distributions of Cash Upon Liquidation

If we dissolve in accordance with our partnership agreement, we will sell or otherwise dispose of our assets in a process called liquidation. Neither the sale of all or substantially all of our property or business, nor the consolidation or merger of us with or into any other entity, individually or in a series of transactions, will be deemed a liquidation. We will apply any proceeds of liquidation available for distribution to our general and limited partners in the manner set forth below.

First, holders of our Series A Preferred Units and Series B Preferred Units will have the right to receive the liquidation preference of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions to the date of payment, whether or not declared.

After such Series A Preferred Unit and Series B Preferred Unit distributions, if, as of the date three trading days prior to the announcement of the proposed liquidation, the average closing price of our common units for the preceding 20 trading days (or the current market price) is greater than the initial public offering common unit price (less any prior capital surplus distributions and any prior cash distributions made on our common units in connection with a partial liquidation), then the proceeds of the liquidation will be applied as follows:

If, as of the date three trading days prior to the announcement of the proposed liquidation, the current market price of our common units is equal to or less than the initial public offering common unit price (less any prior capital surplus distributions and any prior cash distributions made on our common units in connection with a partial liquidation), then the proceeds of the liquidation will be applied as follows:

The immediately preceding two paragraphs are based on the assumption that our general partner maintains its 0.76% general partner interest and that we do not issue additional classes of equity securities.

39

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities (any of which may be senior or subordinated and convertible or not convertible) from time to time in one or more series, under an indenture to be dated as of a date on or prior to our initial issuance of the debt securities. The following description of debt securities sets forth the material terms and provisions of the debt securities to which any prospectus supplement may relate. Our senior debt securities would be issued under a senior indenture, and our subordinated debt securities would be issued under a subordinated indenture. The senior or subordinated indenture for debt securities and any convertible debt securities, forms of which are included as exhibits to the registration statement of which this prospectus is a part, will be executed at the time we issue applicable debt securities. Any supplemental indentures will be filed with the SEC on a Form 6-K or by a post-effective amendment to the registration statement of which this prospectus is a part.

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

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

General

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

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

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

40

Consolidation, Merger and Sale of Assets

The terms of the Indentures in the forms initially filed as exhibits to the registration statement of which this prospectus is a part provide that we may not consolidate with or merge with or into, any other person or sell,

41

assign, convey, transfer, lease our properties and assets as an entirety or substantially as an entirety to any person, unless:

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

Events of Default

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

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

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

The trustee will not be obligated to exercise any of its rights or powers at the request of the holders unless the holders have offered to the trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense. Subject to the applicable Indenture, applicable law and the trustee’s indemnification, the holders of a majority in aggregate principal amount of the outstanding debt securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities. In the event an event of default has occurred

42

and is continuing, the trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs. The trustee, however, may refuse to follow any direction that conflicts with law or the applicable Indenture or that the trustee determines is unduly prejudicial to the rights of any other holder.

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

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

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

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

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

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

43

Modification and Waiver

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

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

The consent of the holders is not necessary under the Indentures to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under an Indenture becomes effective, we are required to mail to the holders a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment.

44

Satisfaction and Discharge

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

Defeasance

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

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

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

45

Transfer and Exchange

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

We reserve the right to:

Payment and Paying Agents

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

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

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

Governing Law

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

46

Concerning the Trustee

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

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

47

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of debt securities, common units, preferred units or other securities. Warrants may be issued independently or together with debt securities, common units, preferred units or other securities offered by any prospectus supplement and may be attached to or separate from any such offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent, all as will be set forth in the prospectus supplement relating to the particular issue of warrants. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders of warrants or beneficial owners of warrants. The summary of the terms of the warrants contained in this prospectus is not complete and is subject to, and is qualified in its entirety to, all provisions of the applicable warrant agreement. Reference is made to the prospectus supplement relating to the particular issue of warrants offered pursuant to such prospectus supplement for the terms of and information relating to such warrants, including, where applicable:

48

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of certain material U.S. federal income tax considerations that may be relevant to prospective unitholders and, unless otherwise noted in the following discussion, is the opinion of Perkins Coie LLP, our U.S. counsel, insofar as it relates to matters of U.S. federal income tax law and legal conclusions with respect to those matters. The opinion of our counsel is dependent on the accuracy of representations made by us to them, including descriptions of our operations contained herein. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (or the Code), legislative history, applicable U.S. Treasury Regulations (or Treasury Regulations), judicial authority and administrative interpretations, all as in effect on the date of this prospectus, and which are subject to change, possibly with retroactive effect, or are subject to different interpretations. Changes in these authorities may cause the tax consequences to vary substantially from the consequences described below.

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

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

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

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

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

49

Election to be Taxed as a Corporation

We have elected to be taxed as a corporation for U.S. federal income tax purposes. As such, unitholders are not directly subject to U.S. federal income tax on our income, but rather are subject to U.S. federal income tax on distributions received from us and dispositions of units as described below.

United States Federal Income Taxation of U.S. Holders

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

Distributions

We have elected to be taxed as a corporation for U.S. federal income tax purposes. Subject to the discussion of passive foreign investment companies (or PFICs) below, any distributions made by us with respect to our units to a U.S. Holder generally will constitute dividends, which may be taxable as ordinary income or “qualified dividend income” as described in more detail below, to the extent of our current and accumulated earnings and profits allocated to the U.S. Holder’s units, as determined under U.S. federal income tax principles. Distributions in excess of our current and accumulated earnings and profits will be treated first as a nontaxable return of capital to the extent of the U.S. Holder’s tax basis in our units and thereafter as capital gain, which will be either long-term or short-term capital gain depending upon whether the U.S. Holder has held the units for more than one year. U.S. Holders that are corporations for U.S. federal income tax purposes generally will not be entitled to claim a dividends received deduction with respect to any distributions they receive from us. For purposes of computing allowable foreign tax credits for U.S. federal income tax purposes, dividends received with respect to our units will be treated as foreign source income and generally will be treated as “passive category income.”

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

Special rules may apply to any “extraordinary dividend” paid by us. Generally, an extraordinary dividend is a dividend with respect to a share of stock if the amount of the dividend is equal to or in excess of 10% of a common stockholder’s, or 5% of a preferred stockholder’s, adjusted tax basis (or fair market value in certain circumstances) in such stock. In addition, extraordinary dividends include dividends received within a one year period that, in the aggregate, equal or exceed 20% of a stockholder’s adjusted tax basis (or fair market value in certain circumstances). If we pay an “extraordinary dividend” on our units that is treated as “qualified dividend income,” then any loss recognized by a Non-Corporate U.S. Holder from the sale or exchange of such units will be treated as long–term capital loss to the extent of the amount of such dividend.

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

50

Sale, Exchange or Other Disposition of Units

Subject to the discussion of PFICs below, a U.S. Holder generally will recognize capital gain or loss upon a sale, exchange or other disposition of our units 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 units. Subject to the discussion of extraordinary dividends above, such gain or loss generally will be treated as (a) long–term capital gain or loss if the U.S. Holder’s holding period is greater than one year at the time of the sale, exchange or other disposition, or short-term capital gain or loss otherwise and (b) U.S. source gain or loss, as applicable, for foreign tax credit purposes. Non-Corporate U.S. Holders may be eligible for preferential rates of U.S. federal income tax in respect of long-term capital gains. A U.S. Holder’s ability to deduct capital losses is subject to certain limitations.

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

Consequences of Possible PFIC Classification

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

There are legal uncertainties involved in determining whether the income derived from our time-chartering activities constitutes rental income or income derived from the performance of services, including legal uncertainties arising from the decision 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. However, the IRS stated in an Action on Decision (AOD 2010-01) that it disagrees with, and will not acquiesce to, the way that the rental versus services framework was applied to the facts in the Tidewater decision, and in its discussion stated that the time charters at issue in Tidewater would be treated as producing services income for PFIC purposes. The IRS’s statement with respect to Tidewater cannot be relied upon or otherwise cited as precedent by taxpayers. Consequently, in the absence of any binding legal authority specifically relating to the statutory provisions governing PFICs, there can be no assurance that the IRS or a court would not follow the Tidewater decision in interpreting the PFIC provisions of the Code. Moreover, the market value of our units may be treated as reflecting the value of our assets at any given time. Therefore, a decline in the market value of our units, which is not within our control, may impact the determination of whether we are a PFIC. Nevertheless, based on our and our subsidiaries’ current assets and operations, we intend to take the position that we are not now and have never been a PFIC, and our counsel, Perkins Coie LLP, is of the opinion that it is more likely than not that we are not a PFIC based on applicable law, including the Code, legislative history, published revenue rulings and court decisions, and representations we have made to them regarding the composition of our assets, the source of our income and the nature of our activities and other operations, including:

51

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

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

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

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

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

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

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 units 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 units, provided the U.S. Holder completes and files IRS Form

52

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 units 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 units at the end of the taxable year over the U.S. Holder’s adjusted tax basis in the units. 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 units over the fair market value thereof at the end of the taxable year that we are a PFIC, but only to the extent of the net amount previously included in income as a result of the mark–to–market election. A U.S. Holder’s tax basis in our units would be adjusted to reflect any such income or loss recognized. Gain recognized on the sale, exchange or other disposition of our units in taxable years that we are a PFIC would be treated as ordinary income, and any loss recognized on the sale, exchange or other disposition of our units 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 U.S. Holder held our units and for which (a) we were not a QEF with respect to such U.S. Holder and (b) such U.S. Holder did not make a timely mark-to-market election, such U.S. Holder would also be subject to the more adverse rules described below in the first taxable year for which the mark-to-market election is in effect and also to the extent the fair market value of the U.S. Holder’s units exceeds the U.S. Holder’s adjusted tax basis in the units 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 (a) any “excess distribution” (i.e., the portion of any distributions received by the Non– Electing Holder on our units in a taxable year in excess of 125% of the average annual distributions received by the Non–Electing Holder in the three preceding taxable years, or, if shorter, the Non–Electing Holder’s holding period for our units), and (b) any gain realized on the sale, exchange or other disposition of our units. Under these special rules:

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

53

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

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

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

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

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

Distributions

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

Sale, Exchange or Other Disposition of Units

In general, a Non-U.S. Holder is not subject to U.S. federal income tax on any gain resulting from the disposition of our units unless (a) such gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment that the Non-U.S. Holder maintains in the United States) or (b) the Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year in which such disposition occurs and meets certain other requirements. If a Non-U.S. Holder is engaged in a trade or business within the United States and the disposition of our units is deemed to be effectively connected to that trade or business, the Non-U.S. Holder generally will be subject to U.S. federal income tax on the resulting gain in the same manner as if it were a U.S. Holder.

Information Reporting and Backup Withholding

In general, payments of distributions with respect to, or the proceeds of a disposition of, our units 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:

54

Non–U.S. Holders may be required to establish their exemption from information reporting and backup withholding on payments made to them within the United States, or through a U.S. payor, by certifying their status on IRS Form W-8BEN, W-8BEN-E, W-8ECI, W-8EXP or W-8IMY, as applicable.

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

NON-UNITED STATES TAX CONSIDERATIONS

Republic of the Marshall Islands Tax Considerations

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

Because we and our subsidiaries do not, and we do not expect that we or any of our subsidiaries will, conduct business, transactions or operations in the Republic of the Marshall Islands, and because all documentation related to this offering will be executed outside of the Republic of the Marshall Islands, under current Republic of the Marshall Islands law holders of our units will not be subject to Republic of the Marshall Islands taxation or withholding on distributions, including upon a return of capital, we make to our unitholders, and holders of our debt securities will not be subject to Republic of the Marshall Islands taxation or withholding on interest paid and return of capital with respect to such debt securities. In addition, our unitholders will not be subject to Republic of the Marshall Islands stamp, capital gains or other taxes on the purchase, ownership or disposition of units, and they will not be required by the Republic of the Marshall Islands to file a tax return relating to the units.

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

Canadian Federal Income Tax Considerations

The following discussion is a summary of the material Canadian federal income tax considerations under the Income Tax Act (Canada) (or the Canada Tax Act) that we believe are relevant to holders of units who, for the purposes of the Canada Tax Act and the Canada-United States Tax Convention 1980 (or the Canada-U.S. Treaty), are at all relevant times resident in the United States and entitled to all of the benefits of the Canada-U.S. Treaty and who deal at arm’s length with us and Teekay Corporation (or U.S. Resident Holders). This discussion takes into account all proposed amendments to the Canada Tax Act and the regulations thereunder that have been publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof and assumes that such proposed amendments will be enacted substantially as proposed. However, no assurance can be given that such proposed amendments will be enacted in the form proposed or at all.

Teekay Offshore Partners L.P. is considered to be a partnership under Canadian federal income tax law and therefore not a taxable entity for Canadian income tax purposes. A U.S. Resident Holder will not be liable to tax under the Canada Tax Act on any income or gains allocated by Teekay Offshore Partners L.P. to the U.S. Resident Holder in respect of such U.S. Resident Holder’s units, provided that (a) Teekay Offshore Partners L.P. does not carry on business in Canada for purposes of the Canada Tax Act and (b) such U.S. Resident Holder does not hold such units in connection with a business carried on by such U.S. Resident Holder through a permanent establishment in Canada for purposes of the Canada-U.S. Treaty.

A U.S. Resident Holder will not be liable to tax under the Canada Tax Act on any income or gain from the sale, redemption or other disposition of such U.S. Resident Holder’s units, provided that, for purposes of the Canada-U.S. Treaty, such units do not, and did not at any time in the twelve-month period preceding the date of disposition, form part of the business property of a permanent establishment in Canada of such U.S. Resident Holder.

We believe that the activities and affairs of Teekay Offshore Partners L.P. are conducted in such a manner that Teekay Offshore Partners L.P. is not carrying on business in Canada and that U.S. Resident Holders should

56

not be considered to be carrying on business in Canada for purposes of the Canada Tax Act or the Canada-U.S. Treaty solely by reason of the acquisition, holding, disposition or redemption of our units. We intend that this is and continues to be the case, notwithstanding that Teekay Shipping Limited (a subsidiary of Teekay Corporation that is a non-resident of Canada) and Teekay Offshore Group Ltd. (an indirect subsidiary of Teekay Offshore Partners L.P. that is a non-resident of Canada) provide certain services to Teekay Offshore Partners L.P. and obtain some or all such services under subcontracts with Canadian service providers. If the arrangements we have entered into result in Teekay Offshore Partners L.P. being considered to carry on business in Canada for purposes of the Canada Tax Act, U.S. Resident Holders would be considered to be carrying on business in Canada and may be required to file Canadian tax returns and, subject to any relief provided under the Canada-U.S. Treaty, would be subject to taxation in Canada on any income that is considered to be attributable to the business carried on by Teekay Offshore Partners L.P. in Canada. The Canada-U.S. Treaty contains a treaty benefit denial rule which may have the effect of denying relief thereunder from Canadian taxation to U.S. Resident Holders in respect of any income attributable to a business carried on by us in Canada.

Although we do not intend to do so, there can be no assurance that the manner in which we carry on our activities will not change from time to time as circumstances dictate or warrant in a manner that may cause U.S. Resident Holders to be carrying on business in Canada for purposes of the Canada Tax Act. Further, the relevant Canadian federal income tax law may change by legislation or judicial interpretation and the Canadian taxing authorities may take a different view than we have of the current law.

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

57

PLAN OF DISTRIBUTION

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

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

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

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

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

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

58

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

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

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

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

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

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

59

SERVICE OF PROCESS AND ENFORCEMENT OF CIVIL LIABILITIES

Teekay Offshore Partners L.P. is formed under the laws of the Republic of the Marshall Islands as a limited partnership. Our general partner is also formed under the laws of the Republic of the Marshall Islands as a limited liability company. 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 the directors and officers of our general partner and those of our subsidiaries 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 the directors and officers of our general partner are located outside the United States. As a result, it may be difficult or impossible for United States investors to effect service of process within the United States upon us, our general partner, our subsidiaries or the directors and officers of our general partner 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.

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

60

LEGAL MATTERS

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

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Under its partnership agreement, in most circumstances, Teekay Offshore Partners L.P. will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages or similar events:

Any indemnification under these provisions will only be out of the assets of Teekay Offshore Partners L.P. Unless it otherwise agrees, Teekay Offshore Partners L.P.’s general partner will not be personally liable for, or have any obligation to contribute or lend funds or assets to Teekay Offshore Partners L.P. to enable it to effectuate, indemnification. Teekay Offshore Partners L.P. may purchase insurance against liabilities asserted against and expenses incurred by persons for its activities, regardless of whether Teekay Offshore Partners L.P. would have the power to indemnify the person against liabilities under the partnership agreement.

Teekay Offshore Partners L.P. is authorized to purchase (or to reimburse its general partners for the costs of) insurance against liabilities asserted against and expenses incurred by its general partner, its affiliates and such other persons as the general partner may determine and described in the paragraph above, whether or not it would have the power to indemnify such person against such liabilities under the provisions described in the paragraphs above. The general partner has purchased insurance covering its officers and directors against liabilities asserted and expenses incurred in connection with their activities as officers and directors of the general partner or any of its direct or indirect subsidiaries.

(a) Exhibits

(b) Financial Statement Schedules

All supplemental schedules are omitted because of the absence of conditions under which they are required or because the information is shown in the financial statements or notes thereto.

(c) Reports, Opinions and Appraisals

The following reports, opinions, and appraisals are included herein: None.

II-2

The Registrant hereby undertakes:

provided, however, that paragraphs 1(a), 1(b) and 1(c) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

II-3

The Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act of 1939, as amended (“Act”), in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.
