The Partnership will file

As filed, such Prospectus shall contain all information required by the Act and the rules thereunder and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Applicable Time or, to the extent not completed at the Applicable Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Partnership has advised you, prior to the Applicable Time, will be included or made therein. The Registration Statement, at the Applicable Time, meets the requirements set forth in Rule 415(a)(1)(x). The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending the effectiveness of the Registration Statement, and no proceeding or examination for such purpose has been instituted or, to the knowledge of the Teekay Parties, threatened by the Commission.

On each Effective Date and at the Applicable Time, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any Option Closing Date, the Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading and the statements made or to be made in such documents that are covered by Rule 175(b) under the Act were made or will be made with a reasonable basis and in good faith; and the documents incorporated by reference in the Registration Statement, any Preliminary Prospectus or the Prospectus did not, and any further documents filed and incorporated by reference therein will not, when filed with the Commission, contain any untrue statement of material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Teekay Parties make no representations or warranties as to the information contained in or omitted from the Registration Statement or the Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Partnership by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement or the Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8(b) hereof.

Each of the Teekay Entities has filed all tax returns that are required to be filed or has requested extensions thereof (except in any case in which the failure so to file would not reasonably be expected to have a Material Adverse Effect) and has paid all taxes required to be paid by it and any other assessment, fine or penalty levied against it, to the extent that any of the foregoing is due and payable, except for any such assessment, fine or penalty that is currently being contested in good faith or as would not reasonably be expected to have a Material Adverse Effect.

Each of the Teekay Entities, other than the Partnership and the General Partner, has properly elected to be classified as a disregarded entity if it has one owner or as a partnership if it has more than one owner for United States federal income tax purposes (other than any Teekay Entity that is classified other than as a corporation without regard to whether it makes an election).

(xx) Foreign Corrupt Practices Act. No Teekay Entity, nor any director, officer, or employee, nor, to the knowledge of the Teekay Parties, any affiliate, agent or representative of the Teekay Entities, has taken or will take any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended (such act, including the rules and regulations thereunder, the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay, or authorization or approval of the payment or giving of money, property, gifts or anything else of value, directly or indirectly, to any “government official” (including any officer or employee of a government or government-owned or controlled entity or of a public international organization, or any person acting in an official capacity for or on behalf of any of the foregoing, or any political party or party official or candidate for political office) to influence official action or secure an improper advantage; and the Teekay Entities have conducted their businesses in compliance with applicable anti-corruption laws and have instituted and maintain and will continue to maintain policies and procedures designed to promote and achieve compliance with such laws and with the representation and warranty contained herein.

“Sanctioned Person”). None of the Teekay Entities is engaged in any dealings or transactions with or for the benefit of a Sanctioned Person, or with or in a country or territory that is, or whose government is, the subject of Sanctions that broadly prohibit dealings with that country or territory (collectively, “Sanctioned Countries” and each, a “Sanctioned Country”), in the preceding three years, nor do any of the Teekay Entities have any plans to deal or transact with or for the benefit of Sanctioned Persons, or with or in Sanctioned Countries.

3. Delivery and Payment. Delivery of and payment for the Firm Units and the Option Units (if the option provided for in Section 2(b) hereof shall have been exercised on or

before the third Business Day immediately preceding the Closing Date) shall be made at 10:00 AM, Eastern time, on January 23, 2018, at the offices of ▇▇▇▇▇▇▇ Coie LLP, Portland, Oregon, or at such time on such later date not more than three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and the Partnership or as provided in Section 9 hereof (such date of delivery and payment for the Units being herein called the “Closing Date”).

(a) Preparation of the Prospectus and Registration Statement. Prior to the termination of the Offering, the Partnership will not file any amendment to the Registration

Statement or supplement to any Preliminary Prospectus or the Prospectus or any Rule 462(b) Registration Statement unless the Partnership has furnished to you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Partnership will cause the Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives, which approval will not be unreasonably withheld or delayed, with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. The Partnership will promptly advise the Representatives (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (ii) when, prior to termination of the Offering, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) Notification Regarding Disclosure Package. If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, the Partnership will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(c) Filing of Amendment or Supplement. If, at any time when a prospectus relating to the Units is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Prospectus to comply with the Act or the rules thereunder, the Partnership promptly will (i) notify the Representatives of any such event; (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 5, an amendment or supplement which will correct such

statement or omission or effect such compliance; and (iii) supply any supplemented prospectus to you in such quantities as you may reasonably request.

(d) Reports to Unitholders. As soon as practicable, but in any event not later than 60 days after the close of the period covered thereby, the Partnership will make generally available to its unitholders and to the Representatives an earnings statement or statements of the Partnership and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(e) Copies of Reports. The Partnership will furnish or make available via the Commission’s Electronic Data Gathering Analysis and Retrieval System (“▇▇▇▇▇”) to its unitholders annual reports containing financial statements audited by independent public accountants and quarterly reports containing financial statements and financial information which may be unaudited. The Partnership will, for a period of two years from the Closing Date, furnish or make available via ▇▇▇▇▇, to the Underwriters a copy of each annual report, quarterly report, current report and all other documents, reports and information furnished by the Partnership to its unitholders (excluding any periodic income tax reporting materials) or filed with any securities exchange or market pursuant to the requirements of such exchange or market or with the Commission pursuant to the Act or the Exchange Act (other than any annual chief executive officer certification and annual written affirmations to the NYSE).

(f) Signed Copies of the Registration Statement. The Partnership will furnish to the Representatives and counsel for the Underwriters photocopies of signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request.

(g) Qualification of Units. The Partnership will arrange, if necessary, for the qualification of the Units for sale under the laws of such jurisdictions as the Representatives may reasonably designate and will maintain such qualifications in effect so long as reasonably required for the distribution of the Units; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Units, in any jurisdiction where it is not now so subject. The Partnership will, from time to time, prepare and file such statements and reports as are or may be reasonably required of it to continue such qualifications in effect for so long a period as the Representatives may reasonably request for the distribution of the Units.

(h) Restriction on Sale of Securities. During a period of 30 days from the date of this Agreement, the Teekay Entities will not, without the prior written consent of the Representatives, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or lend or otherwise transfer or dispose of, the Units, the Series A Preferred Units, the Series B Preferred Units or any non-convertible securities that are substantially similar to the

Units, whether owned as of the date hereof or hereafter acquired or with respect to which such person has or hereafter acquires the power of disposition, or file, or cause to be filed, any registration statement under the Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Units, the Series A Preferred Units, the Series B Preferred Units or such other non-convertible securities that are substantially similar to the Units, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of any Units, Series A Preferred Units, Series B Preferred Units or such other non-convertible securities that are substantially similar to the Units, in cash or otherwise. The foregoing sentence shall not apply to the sale of the Units hereunder to the Underwriters.

(i) Compliance with ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. Each of the Teekay Entities will comply in all material respects with all applicable provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002.

(j) Price Manipulation. The Teekay Entities will not take, directly or indirectly, any action designed to or that would constitute or that could reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Units.

(k) Expenses. The Partnership agrees to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Prospectus, each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Units; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Units, including any stamp or transfer taxes in connection with the original issuance and sale of the Units; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the Offering; (v) the registration of the Units under the Exchange Act and the listing of the Units on the NYSE; (vi) any registration or qualification of the Units for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification); (vii) any filings required to be made with FINRA (including filing fees); (viii) the transportation and other expenses incurred by or on behalf of Partnership representatives in connection with presentations to prospective purchasers of the Units; (ix) the fees and expenses of the Partnership’s accountants and the fees and expenses of counsel (including local and special counsel) for the Partnership; and (x) all other costs and expenses of the Partnership or the Teekay Entities incident to the performance by them of their obligations hereunder. Notwithstanding the foregoing, it is understood that, except as expressly provided in this subsection (k) and Sections 7 and 8 hereof, the Underwriters will pay all of their own costs and expenses, including without limitation, fees and disbursements of their counsel, transfer taxes on the resale by them of any of the Units, the transportation and other expenses incurred by or on their behalf in connection with presentations to potential purchasers of Units and any advertising expenses relating to offers of Units they may make.

(l) Use of Proceeds. The Teekay Entities will use the net proceeds received by them from the sale of the Units as set forth in the Disclosure Package and the Prospectus.

(m) Investment Company; PFIC. For a period of four years after the Closing Date or, if later, any Option Closing Date, the Partnership will use its commercially reasonable efforts to avoid any Teekay Entity, or any subsidiary thereof, from becoming (i) required to register as an “investment company” as defined in the 1940 Act, or (ii) a PFIC with respect to any U.S. unitholder.

(n) PFIC Notice to Unitholders. If the Partnership notifies its unitholders that it or a subsidiary will be a PFIC, it will contemporaneously give similar notice to the Underwriters, along with information concerning the potential availability of a “qualified electing fund” election (or elections) under Section 1295 of the Code or any other applicable election with respect to each Teekay Entity that is a PFIC.

(o) Sanctions Laws and Regulations. The Teekay Entities will not take, and will cause each subsidiary not to take, directly or indirectly, any action that could reasonably be expected to result in a violation by any U.S. person participating in the Offering of any Sanctions with respect to the sale of the Units hereunder. Further, the Partnership will not use, and will cause each subsidiary not to use, the proceeds from the sale of the Units, directly or indirectly, for any purpose or activity that would cause the Underwriters or any purchaser of the Units to be in violation of any Sanctions or for any agent or “Specially Designated National” of any country the subject of Sanctions, or any person or entity of any country the subject of Sanctions.

(p) Final Term Sheet. The Partnership will prepare a final term sheet (the “Final Term Sheet”) containing only a description of the final terms of the Units and their offering, in a form approved by the Representatives and attached as Schedule V hereto, and acknowledges that the Final Term Sheet is an Issuer Free Writing Prospectus and will comply with its related obligations set forth in Section 5(q) hereof. The Partnership will furnish to each Underwriter, without charge, copies of the Final Term Sheet promptly upon its completion.

(q) Issuer Free Writing Prospectuses. The Partnership agrees that, unless it obtains the prior written consent of the Representatives, it will not make any offer relating to the Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433; provided that the Representatives will be deemed to have consented to the Issuer Free Writing Prospectuses listed on Schedule IV hereto and any “road show that is a written communication” within the meaning of Rule 433(d)(8)(i) that has been reviewed by the Representatives. The Partnership represents that it has treated or agrees that it will treat each such free writing prospectus consented to, or deemed consented to, by the Representatives as an Issuer Free Writing Prospectus and that it has complied and will comply with the applicable requirements of Rule 433 with respect thereto, including timely filing with the Commission where required, legending and record keeping. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an

event or condition as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, any Preliminary Prospectus or the Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Partnership will promptly notify the Representatives in writing and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(r) NYSE Listing. The Partnership will use commercially reasonable efforts to effect the listing of the Units on the NYSE within 30 days after the Closing Date and, upon such listing, will use commercially reasonable efforts to maintain such listing and satisfy the requirements for such continued listing.

(s) DTC. The Partnership will use commercially reasonable efforts to assist the Underwriters in arranging for the Units to be eligible for clearance, settlement and trading through the facilities of DTC.

6. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Firm Units and the Option Units, as the case may be, shall be subject to the accuracy of the representations and warranties on the part of the Teekay Parties contained herein as of the Applicable Time, the Closing Date and any Option Closing Date, to the accuracy of the statements of the Teekay Parties made in any certificates delivered pursuant to the provisions hereof, to the performance by the Teekay Parties of their obligations hereunder and to the following additional conditions:

(i) The General Partner shall have furnished to the Underwriters a certificate signed by ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ and ▇▇▇▇▇ ▇▇▇▇, as Chief Executive Officer and Chief Financial Officer, respectively, of Teekay Offshore Group Ltd. dated the Closing Date (or any Option Closing Date, as applicable) and addressed to the Underwriters, to the effect that the signers of such certificate have carefully examined this Agreement, the Registration Statement, the Prospectus, the Disclosure Package, each Non-Prospectus Road Show used in connection with this Offering and any Issuer Free Writing Prospectus and any amendment or supplement thereto and that:

(i) the representations and warranties of the Teekay Parties in this Agreement are true and correct on and as of the Closing Date or any Option Closing Date with the same effect as if made on such date and each Teekay Party has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date or any Option Closing Date;

(ii) such other matters as you may reasonably request.

(k) The Partnership shall have requested and caused KPMG LLP to have furnished to the Underwriters, at the time of execution of this Agreement and at the Closing Date (or any Option Closing Date, as applicable), letters, dated respectively as of the date hereof and as of such Closing Date or Option Closing Date, in form and substance reasonably satisfactory to the Representatives.

(l) Subsequent to the Applicable Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof), the Disclosure Package (exclusive of any supplement thereto) and the Prospectus (exclusive of any supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (k) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the general affairs, management, condition (financial or otherwise), stockholders’ equity, partners’ equity, members’ equity, results of operations, business, properties, assets or prospects of the Teekay Entities taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Registration Statement, the Disclosure Package and the Prospectus (exclusive of any supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package (exclusive of any supplement thereto) and the Prospectus (exclusive of any supplement thereto).

Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Units provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Teekay Parties to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Teekay Parties will reimburse the Underwriters severally through the Representatives on demand for all out of pocket expenses (including reasonable fees and disbursements of counsel) that shall have been reasonably incurred by them in connection with the proposed purchase and sale of the Units.

8. Indemnification and Contribution. (a) The Teekay Parties, jointly and severally, agree to indemnify and hold harmless each Underwriter, the directors, officers, employees, agents and affiliates of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in the Disclosure Package, any Issuer Free Writing Prospectus, any Non-Prospectus Road Show or the Prospectus or in any amendment thereof or supplement thereto or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Teekay Parties will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Teekay Parties through the Representatives by or on behalf of any Underwriter specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Teekay Parties may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Teekay Parties, each of their respective directors, each of their respective officers who signs the Registration Statement, and each person who controls the Teekay Parties within the meaning of either the Act or the Exchange Act, to the same extent as the indemnity in Section 8(a) from the Teekay Parties to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Teekay Parties through the Representatives by or on behalf of such Underwriter specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any

liability which any Underwriter may otherwise have. The Underwriters confirm and the Teekay Parties acknowledge that the statements set forth (i) in the first paragraph under the heading “Underwriting—Underwriting Discounts and Expenses” and (ii) under the heading “Underwriting—Price Stabilization, Short Positions and Penalty Bids” in the Preliminary Prospectus and the Prospectus constitute the only information concerning the Underwriters furnished in writing to the Partnership through the Representatives by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, the Disclosure Package, the Prospectus and any Issuer Free Writing Prospectus or Non-Prospectus Road Show.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ one separate counsel (in addition to local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld, conditioned or delayed), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Teekay Parties, severally and jointly, and the Underwriters, severally, agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which one or more of the Teekay Parties and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Teekay Parties on the one hand and by the Underwriters on the other from the Offering; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the Offering) be responsible for any amount in excess of the underwriting discount or commission applicable to the Units purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Teekay Parties and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Teekay Parties on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Teekay Parties shall be deemed to be equal to the total net proceeds from the Offering (before deducting expenses) received by the Partnership, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Teekay Parties on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Teekay Parties and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls any of the Teekay Parties within the meaning of either the Act or the Exchange Act, each officer of the Teekay Parties who shall have signed the Registration Statement and each director of the Teekay Parties shall have the same rights to contribution as the Teekay Parties, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Units agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Units set forth opposite their names in Schedule I hereto bears to the aggregate amount of Units set forth opposite the names of all the remaining Underwriters) the Units which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the

aggregate amount of Units which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Units set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Units, and if such nondefaulting Underwriters do not purchase all the Units, this Agreement will terminate without liability to any nondefaulting Underwriter or the Teekay Parties. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement, the Disclosure Package, the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Teekay Parties and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Partnership prior to delivery of and payment for the Units, if at any time prior to such time (i) trading in the Partnership’s Common Units, Series A Preferred Units, the Series B Preferred Units or Series E Preferred Units shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Disclosure Package or the Prospectus (in each case exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Teekay Parties or their officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Teekay Parties or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Units. The provisions of Sections 5(k), 7, 8 and 9 hereof shall survive the termination or cancellation of this Agreement.

ANNEX A

Each of the Partnership and the Operating Company has been duly formed and is validly existing in good standing as a limited partnership under ▇▇▇▇▇▇▇▇ Islands Law, and has the limited partnership power and authority to own or lease its properties and to conduct its business, in each case in all material respects, as described in the Registration Statement, the Disclosure Package and the Prospectus.

Each of the General Partner and OLP GP has been duly formed and is validly existing in good standing as a limited liability company under ▇▇▇▇▇▇▇▇ Islands Law, and each has the limited liability company power and authority to own or lease its properties and to conduct its business, in each case in all material respects, as described in the Registration Statement, the Disclosure Package and the Prospectus.

Each of the ▇▇▇▇▇▇▇▇ Islands Subsidiaries is validly existing in good standing as a limited liability company or corporation, as applicable, under ▇▇▇▇▇▇▇▇ Islands Law, and each has the limited liability company or corporate power, as applicable, and authority to own or lease its properties and to conduct its business, in each case in all material respects, as described in the Registration Statement, the Disclosure Package and the Prospectus.

All limited partnership and limited liability company action, as the case may be, required to be taken by the Teekay Parties or any of their respective partners or members pursuant to ▇▇▇▇▇▇▇▇ Islands Law, for the authorization, execution and delivery of the Underwriting Agreement and the Partnership Agreement, and the consummation of the transactions contemplated thereby, has been validly taken.

Each of the Teekay Parties has all requisite limited partnership or limited liability company, as applicable, power and authority to execute and deliver the Underwriting Agreement, and the Partnership Agreement to which it is party, and to perform its obligations thereunder and to consummate the transactions contemplated thereby, including the issuance, sale and delivery of the Preferred Units by the Partnership in accordance with and upon the terms and conditions set forth in the Underwriting Agreement and the Partnership Agreement.

6.	The Underwriting Agreement has been validly executed and delivered by each of the Teekay Parties party thereto.

The Partnership Agreement has been validly executed by the General Partner and constitutes a valid and legally binding obligation of the General Partner, enforceable against the General Partner in accordance with its terms, except that (i) the enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity), and (ii) rights to indemnification and contribution thereunder may be limited by securities laws or considerations of public policy relating thereto.

Assuming that each of Teekay Holdings and Brookfield, has taken all actions necessary to authorize its “acknowledgment and confirmation” of the Partnership Agreement and has validly executed the Partnership Agreement, the Partnership Agreement is enforceable (as defined in the Partnership Agreement) against Teekay Holdings and Brookfield in accordance with its terms, except that (i) the enforceability thereof may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and (ii) the indemnity, contribution and exoneration provisions contained in such agreement may be limited by applicable laws and public policy.

The execution, delivery and performance of the Underwriting Agreement and the Partnership Agreement and the consummation of the transactions contemplated thereby, including the offering, issuance and sale by the Partnership of the Preferred Units in accordance with and upon the terms and conditions set forth in the Underwriting Agreement, do not and will not (i) conflict with or constitute a violation of the organizational documents of any of the Teekay Parties, OLP GP, the Operating Company or the ▇▇▇▇▇▇▇▇ Islands Subsidiaries, (ii) conflict with or constitute a breach or violation of, or a default under (or an event which, with notice or lapse of time or both, would constitute such a default), the Teekay Offshore Partners L.P. 2006 Long-Term Incentive Plan, (iii) violate ▇▇▇▇▇▇▇▇ Islands Law, or (iv) violate any judgment, order or decree of which we are aware of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority situated in the Republic of the ▇▇▇▇▇▇▇▇ Islands directed to any of the Teekay Parties, OLP GP, the Operating Company or the ▇▇▇▇▇▇▇▇ Islands Subsidiaries in a proceeding before such court, regulatory body, administrative agency, governmental body, arbitrator or other authority in the Republic of the ▇▇▇▇▇▇▇▇ Islands to which any of them is a party.

10.

No permit, consent, approval, authorization, order, registration, filing or qualification of or with any court, governmental agency or body of the Republic of the ▇▇▇▇▇▇▇▇ Islands having jurisdiction over the Teekay Parties, OLP GP, the Operating Company, any of the ▇▇▇▇▇▇▇▇ Islands Subsidiaries or any of their respective properties is required in connection with the execution and delivery of the Underwriting Agreement or the Partnership Agreement by the Teekay Parties party thereto, the performance of the transactions contemplated thereby by the Teekay Parties or the performance by the Teekay Parties of their obligations thereunder, including the offering, issuance and sale by the Partnership of the Preferred Units in accordance with and upon the terms and conditions set forth in the Underwriting Agreement and the Partnership Agreement.

11.

The Preferred Units to be issued pursuant to the Underwriting Agreement and the limited partner interests represented thereby have been duly authorized in accordance with the Partnership Agreement and, when issued and delivered to the Underwriters against payment therefor in accordance with the terms of the Underwriting Agreement, will be

validly issued, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 30, 41, 51 and 60 of the ▇▇▇▇▇▇▇▇ Islands Limited Partnership Act and except as may otherwise be provided in the Partnership Agreement). The form of certificate representing the Preferred Units attached as Exhibit D to the Partnership Agreement does not violate ▇▇▇▇▇▇▇▇ Islands Law.

12.

The General Partner owns of record a 0.76% general partner interest (excluding preferred units) in the Partnership and is the sole general partner of the Partnership. Such general partner interest has been duly authorized and validly issued in accordance with the Partnership Agreement. To our knowledge, the General Partner beneficially owns such general partner interest free and clear of all pledges, liens, encumbrances, security interests or other claims, except for the Claims Exceptions. The term “Claim Exceptions” with respect to any limited liability company membership interest, shareholding interest, limited partnership interest or other interest as used herein shall mean: (i) pledges, liens, encumbrances, security interests or other claims as described in, referred to (including by incorporation by reference) or disclosed in the Registration Statement, Disclosure Package, or Prospectus, (ii) any liens pursuant to credit agreements, security agreements or financing documents described in, referred to (including by incorporation by reference) or disclosed in the Registration Statement, Disclosure Package, or Prospectus, and (iii) restrictions on transferability contained in the relevant organizational documents or under applicable securities laws, as applicable.

13.

Teekay Holdings owns of record 51% of the membership interests in the General Partner. Brookfield owns of record 49% of the membership interests in the General Partner. Such membership interests have been duly authorized and validly issued in accordance with the limited liability company agreement of the General Partner, and are fully paid (to the extent required under the General Partner’s limited liability company agreement) and nonassessable (except as such nonassessability may be affected by Sections 20, 31, 40 and 49 of the ▇▇▇▇▇▇▇▇ Islands Limited Liability Company Act of 1996 and except as may be provided in the General Partner limited liability company agreement). For the avoidance of doubt, Brookfield has an option to acquire an additional 2% of the membership interests in the General Partner.

14.

The General Partner owns of record 100% of the Incentive Distribution Rights (as defined in the Partnership Agreement) of the Partnership. To our knowledge, the General Partner beneficially owns such Incentive Distribution Rights free and clear of all pledges, liens, encumbrances, security interests or other claims, except for the Claim Exceptions. As of the date hereof, 38,211,772 common units of the Partnership are owned by Teekay Finance Limited, a Bermuda company (“Teekay Finance”), through brokerage accounts, 16,560,066 are owned of record by Teekay Shipping Limited, a Bermuda company, and 1,815,646 common units of the Partnership are owned of record by Teekay Holdings. These common units of the Partnership and the Incentive Distribution Rights of the Partnership have been duly authorized and validly issued in accordance with the Partnership Agreement, and are fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by

Sections 30, 41, 51 and 60 of the ▇▇▇▇▇▇▇▇ Islands Limited Partnership Act and except as may otherwise be provided in the Partnership Agreement).

15.

ShuttleCo, owns of record a 99.09% limited partnership interest the Operating Company. OLP GP owns of record a 0.91% general partnership interest in the Operating Company. All such partnership interests have been duly authorized and validly issued in accordance with the partnership agreement of the Operating Company, as amended or restated prior to the date hereof, and are fully paid (to the extent required under such partnership agreement) and, with respect to the limited partner interests, are nonassessable (except as such nonassessability may be affected by Sections 30, 41, 51 and 60 of the ▇▇▇▇▇▇▇▇ Islands Limited Partnership Act and except as may otherwise be provided in the partnership agreement of the Operating Company). To our knowledge, ShuttleCo and OLP GP beneficially own such partnership interest free and clear of all pledges, liens, encumbrances, security interests or other claims, except for the Claim Exceptions.

16.

Listed in the “Owner” column of Schedule 1 is the owner of record of the stock or membership interests, as applicable, of each of the ▇▇▇▇▇▇▇▇ Islands Subsidiaries. The stock or membership interests, as applicable, of the entities listed in the “▇▇▇▇▇▇▇▇ Islands Subsidiary” column of Schedule 1 have been duly authorized and validly issued in accordance with the organizational documents of each such ▇▇▇▇▇▇▇▇ Islands Subsidiary, as amended or restated prior to the date hereof, and are fully paid (to the extent required under the organizational documents of each ▇▇▇▇▇▇▇▇ Islands Subsidiary) and nonassessable (except as such nonassessability may be affected by applicable ▇▇▇▇▇▇▇▇ Islands Law and except as may otherwise be provided in the applicable organizational documents). To our knowledge, each ▇▇▇▇▇▇▇▇ Islands entity in the “Owner” column of Schedule 1 hereto beneficially owns the stock or membership interests, as applicable, of each of the entities in the “▇▇▇▇▇▇▇▇ Islands Subsidiary” column of Schedule 1 hereto, free and clear of all pledges, liens, encumbrances, security interests or other claims, except for Claim Exceptions.

17.

Except as described in the Registration Statement, the Disclosure Package or the Prospectus (including in any document or filing incorporated by reference therein), or as otherwise set forth in the Partnership Agreement or the General Partner’s Second Amended and Restated Limited Liability Company Agreement dated September 25, 2017, there are no preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, (i) any limited partner interests in the Partnership or the Operating Company, (ii) any membership interests in the General Partner or OLP GP, or (iii) any equity interests in any ▇▇▇▇▇▇▇▇ Islands Subsidiary (except as provided in Section 78 of the Business Corporations Act of the Republic of the ▇▇▇▇▇▇▇▇ Islands), in each case pursuant to the limited partnership agreement or limited liability company agreement or articles of incorporation or bylaws of such entity.

18.

To our knowledge, no permits, consents, licenses, franchises, concessions, certificates and authorizations of, or declarations or filings with, any governmental or regulatory authorities of the Republic of the ▇▇▇▇▇▇▇▇ Islands are required for any of the Teekay Parties, OLP GP, the Operating Company or the ▇▇▇▇▇▇▇▇ Islands Subsidiaries to own or lease its properties and to conduct its business in the manner described in the Registration

Statement, the Disclosure Package and the Prospectus, other than such permits, consents, licenses, franchises, concessions, certificates and authorizations, declarations or filings with any Republic of the ▇▇▇▇▇▇▇▇ Islands governmental authority (i) currently held or previously obtained, applied, received or filed by any of the Teekay Parties, OLP GP, the Operating Company or the ▇▇▇▇▇▇▇▇ Islands Subsidiaries or (ii) necessary for the ownership, chartering, management or operation of ▇▇▇▇▇▇▇▇ Islands flagged vessels or rigs.

19.

The statements (i) in the Partnership’s Form 20-F for the year ended December 31, 2016 under the captions “Item 4. Information on the Partnership—E. Taxation of the Partnership—▇▇▇▇▇▇▇▇ Islands Taxation” and “Item 10. Additional Information—Non-United States Tax Consequences—▇▇▇▇▇▇▇▇ Islands Tax Consequences” and (ii) in the Disclosure Package and the Prospectus under the captions “Non-United States Tax Considerations—Republic of the ▇▇▇▇▇▇▇▇ Islands Tax Considerations” and “Service of Process and Enforcement of Civil Liabilities,” insofar as they purport to constitute summaries of ▇▇▇▇▇▇▇▇ Islands Law or legal conclusions of ▇▇▇▇▇▇▇▇ Islands Law, fairly describe in all material respects the portions of the statutes and regulations addressed thereby, subject to the qualifications and assumptions stated therein.

20.	The choice of New York law to govern the Underwriting Agreement constitutes a valid choice of law under ▇▇▇▇▇▇▇▇ Islands Law.

21.	The submission by the Partnership in the Underwriting Agreement to the exclusive jurisdiction of any New York court is a valid submission under ▇▇▇▇▇▇▇▇ Islands Law.

22.

A judgment granted by a foreign court against the Partnership may be recognized in the Republic of the ▇▇▇▇▇▇▇▇ Islands, to the extent that the foreign judgment grants or denies recovery of a sum of money, other than a judgment for taxes, a fine or other penalty, or a judgment for support in matrimonial matters, and so long as the judgment is final and conclusive and enforceable where rendered even though an appeal therefrom is pending, or subject to appeal (although the court may stay in proceedings until the relevant appeal has been determined or until the expiration of a period of time sufficient to enable the defendant to prosecute the appeal). A foreign judgment is not conclusive if: (i) the judgment was rendered under a system which does not provide impartial tribunals or procedures compatible with the requirements of due process of law, (ii) the foreign court did not have personal jurisdiction over the defendant, (iii) the foreign court did not have jurisdiction over the subject matter, or (iv) the foreign court does not recognize or enforce the judgments of any other foreign nation. A foreign judgment need not be recognized if: (i) the defendant in the proceedings in the foreign court did not receive notice of the proceedings in sufficient time to enable him to defend, (ii) the judgment was obtained by fraud, (iii) the cause of action on which the judgment is based is repugnant to the public policy of the Republic of the ▇▇▇▇▇▇▇▇ Islands, (iv) the judgment conflicts with another final and conclusive judgment, (v) the proceeding in the foreign court was contrary to an agreement between the parties under which the dispute in question was to be settled otherwise than by proceedings in the court, or (vi) in the case of jurisdiction based only on personal service, the foreign court was a seriously inconvenient forum for the trial of the action.

ANNEX B-1

The statements, with respect to legal matters or legal conclusions, in (a) the Disclosure Package and the Prospectus under the caption “Material United States Federal Income Tax Considerations” and (b) the Partnership’s Form 20-F for the year ended December 31, 2016 (the “Form 20-F”) under the caption “Item 4. Information on the Partnership—Taxation of the Partnership—United States Taxation” are, in all material respects, an accurate discussion of the material U.S. federal income tax considerations addressed therein. (We do not opine or comment on the representations and statements of fact of the Partnership included in such discussion.)

2.	Our opinion filed as Exhibit 8.1 to the Partnership’s Report on Form 6-K furnished to the Commission on January 23, 2018 and incorporated by reference into the Registration Statement is confirmed and the Underwriters may rely upon such opinion as if it were addressed to them.

To our knowledge and except as described in the Registration Statement, the Disclosure Package and the Prospectus, there are no outstanding options or warrants to purchase (a) any Common Units, Series A Preferred Units, Series B Preferred Units, Series E Preferred Units, Incentive Distribution Rights or other interests in the Partnership, or (b) any equity interests in the General Partner, Teekay Offshore Holdings, ShuttleCo, the Operating Company or the Operating Subsidiaries.

To our knowledge, there are no contracts, agreements or understandings between any of the Teekay Entities and any person granting such person the right to require any of the Teekay Entities to file a registration statement under the Act with respect to any securities of any of the Teekay Entities owned or to be owned by such person or to require any of the Teekay Entities to include such securities in the securities registered pursuant to the Registration Statement or in any securities being registered pursuant to any other registration statement filed by any Teekay Entity under the Act, except for any such rights that have been waived or do not apply with respect to the Offering.

The statements (a) in the Disclosure Package and the Prospectus under the captions “Description of Series E Preferred Units” and “The Partnership Agreement” and (b) in subsection b) in the Form 20-F under the caption “Item 7. Major Unitholders and Related Party Transactions – Certain Relationships and Related Party Transactions,” insofar as they constitute descriptions of agreements, fairly describe in all material respects the portions of the agreements addressed thereby, and the Series E Preferred Units conform in all material respects to the descriptions thereof contained in the Disclosure Package and the Prospectus under the captions “Description of Series E Preferred Units” and “The Partnership Agreement.”

The Registration Statement was declared effective by the Commission under the Act on January 10, 2018; the Preliminary Prospectus, each Issuer Free Writing Prospectus and the Prospectus have been filed with the Commission pursuant to Rule 424(b) and Rule 433, as applicable, under the Act, in a manner and within the time period required by the

1933 Act Regulations; and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceeding for that purpose has been instituted or is pending or threatened by the Commission.

Without independent verification of the factual accuracy, completeness or fairness of any statements made in the Registration Statement or the Prospectus, each of the Registration Statement, on the Effective Date, the Disclosure Package, as of the Applicable Time, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) under the Act and on the date hereof (except for the financial statements and financial schedules, and other financial and statistical information included therein, as to which we express no opinion) appears on its face to be appropriately responsive in all material respects to the requirements of the Act and the applicable rules and regulations of the Commission thereunder.

The Partnership’s offering, issuance and sale of the of the Series E Preferred Units, and the Partnership’s and the General Partner’s execution, delivery and performance of the Underwriting Agreement, and consummation of the transactions contemplated by the Underwriting Agreement do not (a) violate statutory or regulatory U.S. federal laws or statutory or regulatory laws of the State of New York that counsel exercising customary professional judgment would in our experience reasonably recognize as typically applicable to agreements similar to the Underwriting Agreement and transactions similar to the transactions contemplated by the Underwriting Agreement, or (b) conflict with or constitute a breach or violation of, or a default under (or an event which, with notice or lapse of time or both, would constitute such a default), any Material Agreement. (We do not comment or opine as to compliance with any financial covenants or financial ratios contained in any such documents.) “Material Agreement” means any indenture, contract, mortgage, deed of trust, note agreement, loan agreement, lease or other agreement or instrument filed by the Partnership as an exhibit to the Registration Statement (including any document filed as an exhibit to any document incorporated by reference into the Registration Statement).

Without independent verification of the factual accuracy, completeness or fairness of the documents incorporated by reference in the Registration Statement and the Prospectus or any further amendment or supplement thereto made by the Partnership prior to the date hereof (other than exhibits thereto and the financial statements and financial schedules, and other financial and statistical information included therein, as to which we express no opinion), when they became effective or were filed with the Commission, as the case may be, each of such documents appears on its face to be appropriately responsive in all material respects to the applicable requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder.

10.

To our knowledge, (a) there is no pending or threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving any Teekay Entity or its property of a character required to be disclosed in the Registration Statement, the Disclosure Package or the Prospectus that is not disclosed in the Registration Statement, the Disclosure Package or the Prospectus as required and

(b) there is no agreement, franchise, contract, indenture, lease or other document or instrument of a character that is required to be described in the Registration Statement, the Disclosure Package or the Prospectus by the Act or to be filed by the Act as an exhibit to the Registration Statement that is not described or filed as required.

11.

All consents, approvals, authorizations or other orders of, or registrations or filings on the part of the Partnership, the General Partner, Brookfield or Teekay Holdings with any United States federal or New York governmental or regulatory authority required for the issuance of the Series E Preferred Units, the execution and delivery by the Partnership and the General Partner of the Underwriting Agreement, the execution and delivery by the General Partner, Brookfield and Teekay Holdings of the Restated Partnership Agreement, and the consummation of the transactions contemplated by the Underwriting Agreement have been made or obtained.

12.

The Partnership is not, and immediately upon giving effect to the Offering, the sale of the Series E Preferred Units and the application of the proceeds thereof as described under “Use of Proceeds” in the Prospectus, will not be, required to register as an “investment company” under the Investment Company Act of 1940, as amended.

13.	The form of the certificate representing the Series E Preferred Units (i) complies with the requirements of the Restated Partnership Agreement and (ii) complies in all material respects with the requirements and rules of the NYSE.

ANNEX B-2

We have participated in conferences with officers and other representatives of the Partnership, representatives of the Underwriters and representatives of the independent auditors of the Partnership at which the contents of the Registration Statement, the Disclosure Package and the Prospectus were discussed. Although we assume no responsibility for the factual accuracy, completeness or fairness of any statements (other than as set forth in paragraphs 1, 2 and 5 of Annex B-1, which remain subject to the assumptions, exclusions and qualifications set forth in this opinion) made in (a) the Registration Statement, (b) the Prospectus, or (c) the documents incorporated by reference in the Registration Statement, nothing has come to our attention that causes us to believe that:
