The Partnership and its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Partnership is not aware of any failures of such internal accounting controls.

Section 3.17 No Material Adverse Change. As of the date hereof, except as set forth on Schedule 3.17 hereto, since September 30, 2014, there has been no change, event, occurrence, effect, fact, circumstance or condition that has had or would reasonably be likely to have a Material Adverse Effect.

Section 3.18 Certain Fees. No fees or commissions are or will be payable by the Partnership to brokers, finders, or investment bankers with respect to the sale of any of the Purchased Units or the consummation of the transactions contemplated by this Agreement. The Partnership agrees that it will indemnify and hold harmless each Purchaser from and against any and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by the Partnership in connection with the sale of the Purchased Units or the consummation of the transactions contemplated by this Agreement.

Section 3.19 No Side Agreements. There are no agreements by, among or between the Partnership or any of its Affiliates, on the one hand, and any Purchaser or any of their Affiliates, on the other hand, with respect to the transactions contemplated hereby other than this Agreement nor promises or inducements for future transactions between or among any of such parties.

Section 3.20 Investment Company Status. The Partnership is not an “investment company” or a company controlled by an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Section 3.21 Passive Foreign Investment Company. To the knowledge of the Partnership, after consultation with United States federal income tax counsel, none of the Partnership Entities is a Passive Foreign Investment Company within the meaning of Section 1297 of the Internal Revenue Code of 1986, as amended.

Section 3.22 Tax Status. None of the Partnership Entities, other than the Partnership and the General Partner, has elected to be classified as an association taxable as a corporation for United States federal

income tax purposes. Each of the Partnership Entities, other than the Partnership and the General Partner, is, or will pursuant to Treasury Regulations Section 301.7701-3 timely and properly elect 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.

Section 3.23 Restricted Securities. The Purchased Units are not characterized as “restricted securities” under the federal securities Laws.

Each Purchaser, severally and not jointly, hereby represents and warrants to the Partnership that:

Section 4.1 Existence. Such Purchaser is duly organized and validly existing and in good standing under the Laws of its jurisdiction of organization, with all requisite power and authority to own, lease, use and operate its Properties and to conduct its business as currently conducted.

Section 4.2 Authorization, Enforceability. Such Purchaser has all necessary corporate, limited liability company or partnership power and authority to execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby, and the execution, delivery and performance by such Purchaser of this Agreement has been duly authorized by all necessary action on the part of such Purchaser; and this Agreement constitutes the legal, valid and binding obligations of such Purchaser, enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar laws affecting creditors’ rights generally or by general principles of equity, including principles of commercial reasonableness, fair dealing and good faith.

Section 4.3 No Breach. The execution, delivery and performance of this Agreement by such Purchaser and the consummation by such Purchaser of the transactions contemplated hereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material agreement to which such Purchaser is a party or by which such Purchaser is bound or to which any of the Property or assets of such Purchaser is subject, (b) conflict with or result in any violation of the provisions of the organizational documents of such Purchaser, or (c) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over such Purchaser or the property or assets of such Purchaser, except in the cases of clauses (a) and (c), for such conflicts, breaches, violations or defaults as would not prevent the consummation of the transactions contemplated by this Agreement.

Section 4.4 Certain Fees. No fees or commissions are or will be payable by such Purchaser to brokers, finders, or investment bankers with respect to the purchase of any of the Purchased Units or the consummation of the transaction contemplated by this Agreement.

Section 4.5 No Side Agreements.

Section 4.7 Short Selling. Such Purchaser has not entered into or effected any Short Sales of the Common Units owned by it between the time it first began discussion with the Partnership about the transactions contemplated by this Agreement and the date hereof (it being understood that, without implication that the contrary would otherwise be true, the entering into of a total return swap shall not be considered a Short Sale of Common Units); provided, however, that, subject to such Purchaser’s compliance with its obligations under the U.S. federal securities laws and its internal policies: (a) such Purchaser, for purposes hereof, shall not be deemed to include any Walled Off Person and (b) the foregoing representations in this paragraph shall not apply to any transaction by or on behalf of Purchaser that was effected by a Walled Off Person in the ordinary course of trading without the advice or participation of Purchaser or receipt of confidential or other information regarding this transaction provided by Purchaser to such entity.²

Section 5.1 Taking of Necessary Action. Each of the parties hereto shall use its commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do or cause to be done all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions contemplated by this Agreement. Without limiting the foregoing, the Partnership and each Purchaser shall use its commercially reasonable efforts to make all filings and obtain all consents of Governmental Authorities that may be necessary or, in the reasonable opinion of the other parties, as the case may be, advisable for the consummation of the transactions contemplated by this Agreement.

Section 5.2 Other Actions. The Partnership shall, prior to the Closing, file a supplemental listing application with the NYSE to list the Purchased Units and file a prospectus supplement to the Prospectus with the Commission to register the Purchased Units in accordance with the Securities Act and the Rules. Each Purchaser agrees solely with the Partnership that its trading activities, if any, with respect to its Purchased Units will be in compliance with all applicable state and federal securities laws, rules and regulations and the rules and regulations of the NYSE.

Section 5.3 Payment and Expenses. The Partnership and each Purchaser shall be responsible for its own fees and expenses in connection with the transactions contemplated by this Agreement.

Section 5.4 Use of Proceeds. The Partnership shall use the collective proceeds from the sale of the Purchased Units for general partnership purposes.

(a) The Partnership will not offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership, or any affiliated company of the Partnership) directly or indirectly, including through the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act and the rules and regulations of the Commission promulgated thereunder with respect to, any Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units; or publicly announce an intention to effect any such transaction, from the date of this

Agreement through the end of December 12, 2014 (the “Restricted Period”), provided, however, that the Partnership may grant restricted units or options to purchase Common Units under the Partnership’s 2006 Long-Term Incentive Plan.

(b) Each Purchaser agrees solely with the Partnership it will not offer, sell, contract to sell, pledge or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by such Purchaser or any affiliate of such Purchaser or any person in privity with such Purchaser or any affiliate of such Purchaser), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Securities and Exchange Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act and the rules and regulations of the Commission promulgated thereunder with respect to the Purchased Units, or publicly announce an intention to effect any such transaction, during the Restricted Period. The Partnership may not waive any or all of the provisions of this Section 5.6(b) with respect to less than all of the Purchasers.

Section 6.1 Indemnification by the Partnership. The Partnership agrees to indemnify each Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Partnership contained herein, provided that such claim for indemnification relating to a breach of the representations or warranties is made prior to the expiration of such representations or warranties; and provided further, that no Purchaser Related Party shall be entitled to recover special, indirect, incidental, consequential (including lost profits or diminution in value) or punitive damages. Notwithstanding anything to the contrary, indirect, incidental and consequential damages shall not be deemed to include diminution in value of the Purchased Units to the extent resulting from, arising out of or in any way related to the breach of any of the representations, warranties or covenants of the Partnership contained herein, which is specifically included in damages covered by the Purchaser Related Parties’ indemnification.

Section 6.2 Indemnification by Purchasers. Each Purchaser agrees, severally and not jointly, to indemnify the Partnership, the General Partner and their respective Representatives (collectively, “Partnership Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of such Purchaser contained herein, provided that such claim for indemnification relating to a breach of the representations and warranties is made prior to the expiration of such representations and warranties; and provided further, that no Partnership Related Party shall be entitled to recover special, indirect, incidental, consequential (including lost profits or diminution in value) or punitive damages.

Section 6.3 Indemnification Procedure. Promptly after any Partnership Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle any such action or claim, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are

different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

Section 7.1 Interpretation and Survival of Provisions. Article, Section, Schedule, and Exhibit references are to this Agreement, unless otherwise specified. All references to instruments, documents, contracts, and agreements are references to such instruments, documents, contracts, and agreements as the same may be amended, supplemented, and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to.” Whenever any party has an obligation under this Agreement, the expense of complying with that obligation shall be an expense of such party unless otherwise specified. Whenever any determination, consent, or approval is to be made or given by any Purchaser, such action shall be in such Purchaser’s sole discretion unless otherwise specified in this Agreement. If any provision in this Agreement is held to be illegal, invalid, not binding, or unenforceable, such provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid, not binding, or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions shall remain in full force and effect. This Agreement has been reviewed and negotiated by sophisticated parties with access to legal counsel and shall not be construed against the drafter.

Section 7.2 Survival of Provisions. The representations and warranties set forth in Sections 3.1, 3.2, 3.3, 3.7, 3.10, 3.11, 3.12, 3.17, 3.18, 3.19, 4.4, and 4.5 hereunder shall survive the execution and delivery of this Agreement indefinitely, and the other representations and warranties set forth herein shall survive for a period of twelve (12) months following the Closing Date regardless of any investigation made by or on behalf of the Partnership or any Purchaser. The covenants made in this Agreement shall survive the Closing of the transactions described herein and remain operative and in full force and effect regardless of acceptance of any of the Purchased Units and payment therefor and repayment, conversion, exercise or repurchase thereof. All indemnification obligations of the Partnership and the Purchasers pursuant to this Agreement and the provisions of Article VI shall remain operative and in full force and effect unless such obligations are expressly terminated in a writing by the parties, regardless of any purported general termination of this Agreement.

(a) Delay. No failure or delay on the part of any party in exercising any right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power, or remedy preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

(b) Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification, or termination of any provision of this Agreement shall be effective unless signed by each of the parties thereto. Any amendment, supplement or modification of or to any provision of this Agreement, any waiver of any provision of this Agreement, and any consent to any departure by the Partnership from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on the Partnership in any case shall entitle the Partnership to any other or further notice or demand in similar or other circumstances.

(a) Binding Effect. This Agreement shall be binding upon the Partnership, the Purchasers, and their respective successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and permitted assigns.

(b) Assignment of Rights. All or any portion of the rights and obligations of any Purchaser under this Agreement may be transferred by such Purchaser to any Affiliate of such Purchaser without the consent of the Partnership. No portion of the rights and obligations of any Purchaser under this Agreement may be transferred by such Purchaser to a non-Affiliate without the prior written consent of the Partnership (which consent shall not be unreasonably withheld by the Partnership). As a condition to any assignment hereunder, the assignee shall agree in writing to be bound by the provisions of this Agreement. The Partnership may not transfer any of its rights or obligations under this Agreement to any Person.

Section 7.5 Communications. All notices and demands provided for hereunder shall be in writing and shall be given by registered or certified mail, return receipt requested, telecopy, air courier guaranteeing overnight delivery or personal delivery to the following addresses:

or to such other address as the Partnership or such Purchaser may designate in writing. All notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; at the time of transmittal, if sent via electronic mail; upon actual receipt if sent by certified mail, return receipt requested, or regular mail, if mailed; when receipt acknowledged, if sent via facsimile; and upon actual receipt when delivered to an air courier guaranteeing overnight delivery.

Section 7.8 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, including facsimile or .pdf format counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement.

(a) Notwithstanding anything herein to the contrary, this Agreement may be terminated at any time at or prior to the Closing by (i) with respect to any particular Purchaser, the written consent of such Purchaser, upon a breach in any material respect by the Partnership of any covenant or agreement set forth in this Agreement or (ii) with respect to any particular Purchaser, written notice by the Partnership to such Purchaser upon a breach in any material respect by such Purchaser of any covenant or agreement set forth in this Agreement. For the avoidance of doubt, the termination of this Agreement with respect to any particular Purchaser shall not affect the Agreement with respect to any other Purchaser.

(b) Notwithstanding anything herein to the contrary, this Agreement shall automatically terminate (i) at any time at or prior to the Closing if a statute, rule, order, decree or regulation shall have been enacted or promulgated, or if any action shall have been taken by any Governmental Authority of competent jurisdiction that permanently restrains, permanently precludes, permanently enjoins or otherwise permanently prohibits the consummation of the transactions contemplated by this Agreement or makes the transactions contemplated by this Agreement illegal or (ii) if the Closing shall not have occurred by December 5, 2014.

(c) In the event of the termination of this Agreement as provided in this Section 7.9, (1) this Agreement shall forthwith become null and void, and (2) there shall be no liability on the part of any Party hereto, except as set forth in Sections 5.3 and Article VI of this Agreement.

See Item 1 – Financial Statements: Note 11(a) – Commitments and Contingencies, in the Partnership’s Form 6-K for the quarter ended September 30, 2014.

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Common Unit Purchase Agreement (the “Purchase Agreement”). The Partnership shall furnish to the Purchasers at the Closing an opinion of Perkins Coie LLP, counsel for the Partnership, addressed to the Purchasers and dated the Closing Date in form reasonably satisfactory to the Purchasers, stating that:

(i) To our knowledge, except as described in the Partnership SEC Documents filed prior to the date of the Purchase Agreement, there are no outstanding options, warrants, or agreements for the purchase or acquisition from the Partnership of Partnership securities or ownership interests in the Partnership, or rights to convert any obligations into or exchange any securities for Partnership securities or ownership interests in the Partnership.

(ii) No consent, approval, authorization or other action by, or filing with, any Governmental Authority is required for the issuance and sale by the Partnership of the Purchased Units, the execution, delivery and performance by the Partnership of the Agreement or the completion of the transactions contemplated by the Agreement, except for those that have been obtained or as may be required under state securities or “Blue Sky” laws, as to which we do not express any opinion.

(iii) To our knowledge, there are no contracts, agreements or understandings between any of the Partnership Entities and any person granting such person the right to require any of the Partnership Entities to file a registration statement under the Securities Act with respect to any securities of the Partnership owned or to be owned by such person or to require any of the Partnership Entities to include such securities in any securities being registered pursuant to any other registration statement filed by any Partnership Entity under the Securities Act, except for any such rights held by the General Partner or an Affiliate (as defined in the Partnership Agreement) of the General Partner pursuant to the Partnership Agreement and except for such rights granted pursuant to the Existing Registration Rights Agreements.

(iv) None of the offering, issuance and sale by the Partnership of the Purchased Units, the execution, delivery and performance of the Agreement by the Partnership, or the completion of the transactions contemplated thereby conflicts with or constitutes 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 indenture, contract, mortgage, deed of trust, note agreement, loan agreement, lease or other agreement or instrument filed as an exhibit to the Partnership’s Annual Report on Form 20-F for the year ended December 31, 2013, or the Quarterly Reports on Form 6-K for the quarters ended March 31, June 30 and September 30, 2014 (including any document filed as an exhibit to any document incorporated by reference therein). (We do not comment or opine as to compliance with any financial covenants or financial ratios contained in any such documents.)

(v) The Partnership is not, and after giving effect to the use of proceeds from the sale of the Purchased Units pursuant to the Purchase Agreement will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(vi) We confirm that the Common Units of the Partnership are listed on the New York Stock Exchange, and, consequently, the Purchased Units, when issued and delivered by the Partnership pursuant to the terms of the Purchase Agreement, will be “covered securities” for purposes of Section 18 of the Securities Act.

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Common Unit Purchase Agreement (the “Purchase Agreement”). The Partnership shall furnish to the Purchasers at the Closing an opinion of Watson, Farley & Williams LLP, special Marshall Islands and New York counsel for the Partnership, addressed to the Purchasers and dated the Closing Date in form reasonably satisfactory to the Purchasers, stating that:

(i) Each of the Partnership and the Operating Company has been duly formed and is validly existing in good standing as a limited partnership under the law of the Republic of the Marshall Islands, 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 Partnership SEC Documents.

(ii) Each of the General Partner and the OLP GP has been duly formed and is validly existing in good standing as a limited liability company under the law of the Republic of the Marshall Islands, 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 Partnership SEC Documents.

(iii) Each of the entities listed in Schedule A to such opinion (the “Marshall Islands Significant Subsidiaries”) is validly existing in good standing as a limited liability company or corporation, as applicable, under Marshall 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 Partnership SEC Documents.
