The Partnership agrees that it may issue and sell through or to each Agent, as sales agent or principal, common units representing limited partnership interests (the “Common Units”), from time to time during the term of this Agreement and on the terms set forth in this Agreement; provided, however, that in no event shall the Partnership issue or sell through or to such Agent such number of Common Units that (a) exceed the number of units or dollar amount of Securities registered on the effective Registration Statement (as defined below) pursuant to which the offering is being made, or (b) exceeds the number of authorized but unissued Common Units (the lesser of (a) and (b), the “Maximum Amount”). For the avoidance of doubt, the term “Securities” as used in this Agreement refers only to the Common Units to be sold pursuant to this Agreement. Notwithstanding anything to the contrary contained herein, the parties hereto agree that compliance with the limitations set forth in this Section 1 regarding the number and aggregate sale price of the Securities shall be the sole responsibility of the Partnership, and that the Agents shall have no obligation in connection with such compliance. The issuance and sale of the Securities through the Agents will be effected pursuant to the Registration Statement (as defined below) filed by the Partnership and declared effective by the Securities and Exchange Commission (the “Commission”), although nothing in this Agreement shall be construed as requiring the Partnership to use the Registration Statement to issue any Securities.

The Partnership has filed, in accordance with the provisions of the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations thereunder (the “Securities Act Regulations”), with the Commission, a registration statement on Form F-3 (File No. 333-240014), including a base prospectus, relating to certain securities, including the Securities to be issued from time to time by the Partnership, and which incorporates by reference documents that

The Partnership will furnish to the Agents, for use by the Agents, electronic copies of the base prospectus included as part of such registration statement, as supplemented by one or more Prospectus Supplements, relating to the Securities. Except where the context otherwise requires, August 19, 2020, and any post-effective amendment thereto, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a Prospectus (as defined below) subsequently filed with the Commission pursuant to Rule 424(b) under the Securities Act or deemed to be a part of such registration statement pursuant to Rule 430B of the Securities Act, or any subsequent registration statement on Form F-3 filed pursuant to Rule 415(a)(6) under the Securities Act by the Company to cover any Placement Shares, is herein called the “Registration Statement.” The base prospectus, including all documents incorporated or deemed incorporated therein by reference to the extent such information has not been superseded or modified in accordance with Rule 412 under the Securities Act (as qualified by Rule 430B(g) of the Securities Act), included in the Registration Statement, as it may be supplemented by one or more Prospectus Supplements, in the form in which such base prospectus and/or a Prospectus Supplement have most recently been filed by the Partnership with the Commission pursuant to Rule 424(b) under the Securities Act, is herein called the “Prospectus.” Any reference herein to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the documents incorporated or deemed incorporated by reference therein, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include the filing after the execution hereof of any document with the Commission deemed to be incorporated by reference therein (the “Incorporated Documents”).

The submission by the Partnership Parties in this Agreement to the non-exclusive jurisdiction of the federal or state courts of the United States of America located in the City and County of New York, Borough of Manhattan, constitutes a valid and legally binding obligation of the Partnership and service of process made in the manner set forth in this Agreement will be effective to confer valid personal jurisdiction over the Partnership for purposes of proceedings in such courts under the laws of their respective jurisdiction of formation or incorporation.

ccc. Enforceability of Foreign Judgments. Pursuant to the terms of this Agreement, the Partnership Parties have agreed to submit to the jurisdiction of any state or federal court in the state of New York in which the relevant suit or proceeding may be instituted.

iii. furnishes its unaudited interim financial statements and management’s discussion and analysis on Form 6-K under the Exchange Act or any date on which an amendment to any such document is filed or furnished under the Exchange Act.

(Each date of filing of one or more of the documents referred to in clauses (i) through (iii) shall be a “Representation Date.”)

the Partnership shall furnish the Agents with a certificate, in the form attached hereto as Exhibit A within five (5) Trading Days of any Representation Date, provided, however, in the case of clause (i) above, the Partnership shall furnish the Agents with a certificate, in the form attached hereto as Exhibit A on or prior to delivery of the first Placement Notice relating to the Securities. The requirement to provide a certificate under this Section 7(1) shall be deemed waived by the Agents for any Representation Date occurring at a time at which no Placement Notice is pending, which waiver shall continue until the earlier to occur of the date the Partnership delivers a Placement Notice hereunder (which for such calendar quarter shall be considered a Representation Date) and the next occurring Representation Date on which the Partnership files its annual report on Form 20-F. Notwithstanding the foregoing, (i) upon the delivery of the first Placement Notice hereunder and (ii) if the Partnership subsequently decides to sell Placement Securities following a Representation Date when the Partnership relied on such waiver and did not provide the Agents with a certificate under this Section 7(1), then before the Agents sell any Placement Securities, the Partnership shall provide the Agents with a certificate, in the form attached hereto as Exhibit A, dated the date of the Placement Notice.

m. Legal Opinions of Counsel. (A) On or prior to the date of the delivery of the first Placement Notice relating to the Securities, and (B) within five (5) Trading Days of each Representation Date with respect to which the Partnership is obligated to deliver a certificate in the form attached hereto as Exhibit A for which no waiver is applicable, the Partnership shall cause to be furnished to the Agents written opinions, in form and substance agreed to between the Parties, (in the case of clause (A)) and a negative assurance letter (in the case of clauses (A) and (B)) of Xxxxxx & Xxxxxx LLP, U.S., Xxxxxxxx Islands Counsel, (collectively, the “Partnership Counsel”), or other counsel reasonably satisfactory to the Agents, dated the date that the opinion or negative assurance letter is required to be delivered; provided, however, that in lieu of such negative assurance for subsequent Representation Dates, Partnership Counsel may furnish the Agents with a written letter (a “Reliance Letter”) to the effect that the Agents may rely on a prior opinion previously delivered under this Section 7(m) to the same extent as if it were dated the date of such letter (except that statements in such prior opinion shall be deemed to relate to the Registration Statement and the Prospectus as amended or supplemented at such Representation Date).

n. Comfort Letter. (A) On or prior to the date of delivery of the first Placement Notice relating to the Securities and within five (5) Trading Days after the filing by the Partnership of an annual report on Form 20-F under the Exchange Act, the Partnership shall cause its independent accountants (and any other independent accountants whose report is included or incorporated by reference in the Registration Statement or the Prospectus, pursuant

to Rule 3-05 of Regulation S-X or otherwise) to furnish the the Agents letters (the “Comfort Letters”), dated the date that such Comfort Letter is delivered, which shall meet the requirements set forth in this Section 7(n); provided, that if requested by the Agents, the Partnership shall cause a Comfort Letter to be furnished to the Agents within ten (10) Trading Days of such request following the date of occurrence of any restatement of the Partnership’s financial statements. The Comfort Letter shall be in the form and substance customarily used by the Partnership’s independent accountants for transactions of this type and reasonably satisfactory to the Agents, (i) confirming that they are an independent public accounting firm within the meaning of the Securities Act, the Securities Act Regulations and the PCAOB, (ii) stating, as of such date, the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with registered public offerings (the first such letter, the “Initial Comfort Letter”) and (iii) updating the Initial Comfort Letter with any information that would have been included in the Initial Comfort Letter had it been given on such date and modified as necessary to relate to the Registration Statement and the Prospectus, as amended and supplemented to the date of such letter.

o. Market Activities. The Partnership will not, directly or indirectly, (i) take any action designed to cause or result in, or that constitutes or would reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Securities or (ii) sell, bid for, or purchase Securities in violation of Regulation M, or pay anyone any compensation for soliciting purchases of the Placement Securities other than the Agents.

p. No Offer to Sell. Other than a Permitted Free Writing Prospectus, neither the Agents nor the Partnership (including its agents and representatives, other than the Agents, in its capacity as such) will make, use, prepare, authorize, approve or refer to any written communication (as defined in Rule 405), required to be filed with the Commission, that constitutes an offer to sell or solicitation of an offer to buy Placement Securities hereunder.

x. Xxxxxxxx-Xxxxx Act. The Partnership will use its best efforts to comply with all effective applicable provisions of Xxxxxxxx-Xxxxx.

8. Representations and Covenants of the Agents. Each Agent represents and warrants that it is duly registered as a broker-dealer under FINRA, the Exchange Act and the applicable statutes and regulations of each state in which the Placement Securities will be offered and sold, except such states in which such Agent is exempt from registration or such registration is not otherwise required. Each Agent shall continue, for the term of this Agreement, to be duly registered as a broker-dealer under FINRA, the Exchange Act and the applicable statutes and regulations of each state in which the Placement Securities will be offered and sold, except such states in which such Agent is exempt from registration or such registration is not otherwise required, during the term of this Agreement.

The obligations of each Agent hereunder with respect to a Placement will be subject to the continuing accuracy and completeness of the representations and warranties made by the Partnership Parties herein, to the due performance by the Partnership Parties of its obligations hereunder, to the completion by each Agent of a due diligence review satisfactory to it in its reasonable judgment, and to the continuing satisfaction (or waiver by such Agent in its sole discretion) of the following additional conditions:

11. Indemnification and Contribution.

a. Indemnification by the Partnership Parties. The Partnership Parties agree, jointly and severally, to indemnify and hold harmless each Agent, its partners, members, directors, officers, employees and agents and each person, if any, who controls such Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

i. against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of any untrue statement or alleged untrue statement of a material fact included in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

ii. against any and all loss, liability, claim, damage and expense whatsoever, as incurred, joint or several, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 11(d) below) any such settlement is effected with the written consent of the Partnership, which consent shall not unreasonably be delayed or withheld; and

iii. against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Partnership by such Agent expressly for use in the Registration Statement (or any amendment thereto), or in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto).

b. Indemnification by the Agents. Each Agent, severally and not jointly, agrees to indemnify and hold harmless the Partnership Parties and each of its directors and officers of the General Partner who signed the Registration Statement, and each person, if any,

who (i) controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act or (ii) is controlled by or is under common control with the Partnership against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 11(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendments thereto) or in any related Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information relating to such Agent and furnished to the Partnership in writing by such Agent expressly for use therein.

c. Procedure. Any party that proposes to assert the right to be indemnified under this Section 11 will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 11, notify as promptly as reasonably practicable each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but failure to so notify such indemnifying party will not relieve the indemnifying party from (i) any liability that it might have to any indemnified party otherwise than under this Section 11 and (ii) any liability that it may have to any indemnified party under the foregoing provision of this Section 11 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (1) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (2) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (3) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party) or (4) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges will be reimbursed by the indemnifying party promptly after the indemnifying party receives a written

invoice relating to fees, disbursements and other charges in reasonable detail. An indemnifying party will not, in any event, be liable for any settlement of any action or claim effected without its written consent. No indemnifying party shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 11 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent (1) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (2) 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. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 11 is applicable in accordance with its terms but is for any reason unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, liabilities, expenses and damages referred to therein, then each indemnifying party shall contribute to the total amount of such losses, claims, liabilities, expenses and damages incurred by such indemnified party as incurred (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the indemnified party from persons other than any indemnified party, who also may be liable for contribution) (A) in such proportion as shall be appropriate to reflect the relative benefits received by the Partnership Parties on the one hand and each Agent on the other hand from the offering of the Placement Securities pursuant to this Agreement or (B) if the allocation provided by clause (A) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (A) above but also the relative fault of the Partnership Parties on the one hand and of such Agent on the other hand in connection with the statements or omissions that resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or such Agent, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Partnership Parties and the Agents agree that it would not be just and equitable if contributions pursuant to this Section 11(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense, or damage, or action in respect thereof, referred to above in this Section 11(d) shall be deemed to include, for the purpose of this Section 11(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim to the extent consistent with Section 11(c) hereof.

Notwithstanding the foregoing provisions of this Section 11(d), an Agent shall not be required to contribute any amount in excess of the commissions received by it under this Agreement and no person found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person who was not

guilty of such fraudulent misrepresentation. The obligations of each Agent under this Section 11(d) to contribute are several and not joint.

For purposes of this Section 11(d), any person who controls a party to this Agreement within the meaning of the Securities Act or the Exchange Act, and any officers, directors, partners, employees or agents of an Agent, will have the same rights to contribution as that party, and each officer and director of the General Partner who signed the Registration Statement will have the same rights to contribution as the Partnership Parties, subject in each case to the provisions hereof. Any party entitled to contribution, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made under this Section 11(d), will notify any such party or parties from whom contribution may be sought, but the omission to so notify will not relieve that party or parties from whom contribution may be sought from any other obligation it or they may have under this Section 11(d) except to the extent that the failure to so notify such other party materially prejudiced the substantive rights or defenses of the party from whom contribution is sought. Except for a settlement entered into pursuant to the last sentence of Section 11(c) hereof, no party will be liable for contribution with respect to any action or claim settled without its written consent if such consent is required pursuant to Section 11(c) hereof.

12. Representations and Agreements to Survive Delivery. The indemnity and contribution agreements contained in Section 11 of this Agreement and all representations and warranties of the Partnership herein or in certificates delivered pursuant hereto shall survive, as of their respective dates, regardless of (i) any investigation made by or on behalf of the Agents, any controlling persons, or the Partnership Parties (or any of their officers, directors or controlling persons), (ii) delivery and acceptance of the Placement Securities and payment therefor or (iii) any termination of this Agreement.

13. Termination.

a. Termination; General. An Agent may terminate this Agreement, by notice to the Partnership Parties, as hereinafter specified at any time (A) if there has been, since the time of execution of this Agreement or since the date as of which information is given in the Prospectus, any Material Adverse Effect, or any development that is reasonably likely to have a Material Adverse Effect or, in the sole judgment of such Agent, is material and adverse and makes it impractical or inadvisable to market the Placement Securities or to enforce contracts for the sale of the Placement Securities, (B) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of such Agent, impracticable or inadvisable to market the Placement Securities or to enforce contracts for the sale of the Placement Securities, (C) if trading in the Common Units has been suspended or limited by the Commission or the NYSE, or if trading generally on the NYSE has been suspended or limited, or minimum prices for trading have been fixed on the NYSE, (D) if any suspension of trading of any securities of the Partnership on any exchange or in the over-the-counter market shall have occurred and be continuing, (E) if a major disruption of securities settlements or clearance services in the United States shall have occurred and be continuing, or (F) if a banking moratorium has been declared by either U.S. Federal or New York authorities.

Any such termination shall be without liability of any party to any other party except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination. If an Agent elects to terminate this Agreement as provided in this Section 13(a), such Agent shall provide the required notice as specified in Section 14 (Notices).

b. Termination by the Partnership. The Partnership shall have the right, by giving three (3) days’ notice as hereinafter specified, to terminate this Agreement in its sole discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination.

c. Termination by the Agents. Each Agent shall have the right, by giving three (3) days’ notice as hereinafter specified, to terminate this Agreement with respect to itself in its sole discretion at any time after the date of this Agreement. Any such termination shall be without liability of any party to any other party except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination.

d. Automatic Termination. Unless earlier terminated pursuant to this Section 13, this Agreement shall automatically terminate upon the issuance and sale of all of the Securities through the Agents on the terms and subject to the conditions set forth herein except that the provisions of Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) hereof shall remain in full force and effect notwithstanding such termination.

e. Continued Force and Effect. This Agreement shall remain in full force and effect unless terminated pursuant to Section 13(a), (b), (c), or (d) above or otherwise by mutual agreement of the parties; provided, however, that any such termination by mutual agreement shall in all cases be deemed to provide that Section 9 (Payment of Expenses), Section 11 (Indemnification and Contribution), Section 12 (Representations and Agreements to Survive Delivery), Section 18 (Governing Law and Time; Waiver of Jury Trial) and Section 19 (Consent to Jurisdiction) shall remain in full force and effect. Upon termination of this Agreement, the Partnership Parties shall not have any liability to the Agents for any discount, commission or other compensation with respect to any Placement Securities not otherwise sold by the Agents under this Agreement.

f. Effectiveness of Termination. Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided, however, that such termination shall not be effective until the close of business on the date of receipt of such notice

by the Agents or the Partnership Parties, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of Placement Securities, such Placement Securities shall settle in accordance with the provisions of this Agreement.

20. Use of Information. The Agents may not use any information gained in connection with this Agreement and the transactions contemplated by this Agreement, including due diligence, to advise any party with respect to transactions not expressly approved by the Partnership Parties.

21. Currency. The obligation of the Partnership Parties pursuant to this Agreement in respect of any sum due to the Agents shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day, following receipt by the Agents of any sum adjudged to be so due in such other currency, on which (and only to the extent that) the Agents may in accordance with normal banking procedures purchase United States dollars with such other currency; if the United States dollars so purchased are less than the sum originally due to the Agents hereunder, the Partnership Parties agree, as a separate obligation and notwithstanding any such judgment, to indemnify the Agents against such loss.

23. Effect of Headings. The section and Exhibit headings herein are for convenience only and shall not affect the construction hereof.

24. Permitted Free Writing Prospectuses. The Partnership represents, warrants and agrees that, unless it obtains the prior consent of the Agents, and each Agent represents, warrants and agrees that, unless it obtains the prior consent of the Partnership, it has not made and will not make any offer relating to the Placement Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Agents or by the Partnership, as the case may be, is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership represents and warrants that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping. For the purposes of clarity, the parties hereto agree that all free writing prospectuses, if any, listed in Exhibit B hereto are Permitted Free Writing Prospectuses.

25. Absence of Fiduciary Relationship. The Partnership Parties acknowledge and agree that:

a. each Agent is acting solely as agent in connection with the public offering of the Placement Securities and in connection with each transaction contemplated by this Agreement and the process leading to such transactions, and no fiduciary or advisory relationship between the Partnership Parties or any of its affiliates, unitholders (or other equity holders), creditors or employees or any other party, on the one hand, and such Agent, on the other hand, has been or will be created in respect of any of the transactions contemplated by this Agreement, irrespective of whether or not such Agent has advised or is advising the Partnership Parties on other matters, and the Agents have no obligation to the Partnership Parties with respect to the transactions contemplated by this Agreement except the obligations expressly set forth in this Agreement;

b. it is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement;

c. each Agent has not provided any legal, accounting, regulatory or tax advice with respect to the transactions contemplated by this Agreement and it has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate;

d. it is aware that each Agent and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Partnership Parties and such Agent has no obligation to disclose such interests and transactions to the Partnership Parties by virtue of any fiduciary, advisory or agency relationship or otherwise; and

e. it waives, to the fullest extent permitted by law, any claims it may have against any Agent for breach of fiduciary duty or breach of fiduciary duty in connection with the sale of Placement Securities under this Agreement and agrees that such Agent shall not have any liability (whether direct or indirect, in contract, tort or otherwise) to it in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on its behalf or in right of it or the Partnership Parties, employees or creditors of Partnership Parties, other than in respect of such Agent’s obligations under this Agreement and to keep information provided by the Partnership Parties to such Agent and such Agent’s counsel confidential to the extent not otherwise publicly-available.

26. Amendment and Restatement of Existing Sales Agreement. On July 2, 2020, the Partnership entered into an ATM Sales Agreement (the “Existing Sales Agreement”) with Virtu. The Partnership and Virtu wish to amend and restate the Existing Sales Agreement in its entirety as provided herein.
