Ladies and Gentlemen:

Buckeye Partners, L.P., a Delaware limited partnership (the “Partnership”), and Buckeye GP, LLC, a Delaware limited liability company and the general partner of the Partnership (the “General Partner”), confirm their agreement with ▇.▇. ▇▇▇▇▇▇ Securities LLC, BB&T Capital Markets, a division of BB&T Securities, LLC, BNP Paribas Securities Corp., Deutsche Bank Securities Inc., ▇▇▇▇▇▇▇▇▇ LLC, ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC, RBC Capital Markets, LLC, and SMBC Nikko Securities America, Inc., as agent and/or principal under any Terms Agreement (as defined in Section 1(a) below) (each an “Agent” and collectively the “Agents”) with respect to the issuance and sale from time to time by the Partnership, in the manner and subject to the terms and conditions described below in this Distribution Agreement (this “Agreement”), of limited partnership units representing limited partner interests in the Partnership (the “LP Units”) having an aggregate Gross Sales Price (as defined in Section 2(b) below) of up to $500,000,000 (the “Maximum Amount”) on the terms set forth in Section 1 of this Agreement. Such LP Units are hereinafter collectively referred to as the “Securities” and are described in the Prospectus referred to below.

The Partnership has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-200441) (the “registration statement”) for the registration of the Securities and other securities of the Partnership under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”); and such registration statement sets forth the terms of the offering, sale and plan of distribution of the Securities and contains additional information concerning the Partnership and its business. Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Securities Act, as such section applies to the Agents, including (1) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein and (2) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act, to the extent such information is deemed, pursuant to Rule 430B or Rule 430C under the Securities Act, to be part of the registration statement at the time of the registration statement’s effectiveness. “Basic Prospectus” means the prospectus dated January 16, 2015 filed as part of the Registration Statement; “Prospectus Supplement” means the most recent prospectus supplement relating to the Securities, to be filed by the Partnership with the Commission pursuant to Rule 424(b) under the Securities Act on or before the second business day after the date of its first use in connection with a public offering or sale of Securities pursuant hereto (or such earlier time as may be required under the Securities Act), in the form furnished by the Partnership to the Agents in connection with the offering of the Securities; “Prospectus” means the Prospectus Supplement (and any additional prospectus supplement prepared in accordance with the provision of Section 4(h) of this Agreement and filed in accordance with the provisions of Rule 424(b)) together with the Basic Prospectus attached to or used with the Prospectus Supplement; and “Permitted Free Writing Prospectus” has the meaning set forth in Section 3(b). Any reference herein to the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall, unless otherwise stated, be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein as of the date of such document (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents. Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall, unless stated otherwise, be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”) on or after the initial effective date of the Registration Statement, or the date of the Basic Prospectus, the Prospectus Supplement, the Prospectus or such Permitted Free Writing Prospectus, as the case may be, and deemed to be incorporated therein by reference. References in this Agreement to financial statements or other information that is “contained,” “included,” “described,” “set forth” or “provided” in the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus and any similar references shall, unless stated otherwise, include any information incorporated or deemed to be incorporated by reference therein as of the date of such document.

The Partnership, the General Partner, and each Agent agree as follows:

1. Issuance and Sale.

(a) Upon the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein and provided the Partnership and the General Partner provide the applicable Agent with any due diligence materials and information reasonably requested by such Agent necessary for such Agent to satisfy its due diligence obligations, on any Exchange Business Day (as defined below) selected by the Partnership, the Partnership and such Agent shall enter into an agreement in accordance with Section 2 hereof regarding the number of Securities to be placed by such Agent, as agent, and the manner in which and other terms upon which such placement is to occur (each such transaction being referred to as an “Agency Transaction”). The Partnership may also offer to sell the Securities directly to an Agent, as principal, in which event such parties shall enter into a separate agreement (each, a “Terms Agreement”) in substantially the form of Exhibit A hereto (with such changes thereto as may be agreed upon by the Partnership and such Agent to accommodate a transaction involving more than one Agent), relating to such sale in accordance with Section 2(g) of this Agreement (each such transaction being referred to as a “Principal Transaction”). As used herein, (i) the “Term” shall be the period commencing on the date hereof and ending on the earlier of (x) the date on which the aggregate Gross Sales Price of Securities issued and sold pursuant to this Agreement and any Terms Agreements is equal to the Maximum Amount and (y) any termination of this Agreement pursuant to Section 8, (ii) an “Exchange Business Day” means any day during the Term that is a trading day for the Exchange other than a day on which trading on the Exchange is scheduled to close prior to its regular weekday closing time, and (iii) “Exchange” means the New York Stock Exchange.

(b) Subject to the terms and conditions set forth below, the Company appoints each Agent as agent in connection with the offer and sale of Securities in any Agency Transactions entered into hereunder. Each Agent will use its respective commercially reasonable efforts, consistent with its normal trading and sales practices, to sell such Securities in accordance with the terms and subject to the conditions hereof and of the applicable Transaction Acceptance (as defined in Section 2(a) below). Neither the Partnership nor any Agent shall have any obligation to enter into an Agency Transaction. The Partnership shall be obligated to issue and sell through the Agents, and each Agent shall be obligated to use its respective commercially reasonable efforts, consistent with its normal trading and sales practices and as provided herein and in the applicable Transaction Acceptance, to place Securities only if and when the Partnership makes a Transaction Proposal (as defined in Section 2(a) below) to such Agent related to such an Agency Transaction and a Transaction Acceptance related to such Agency Transaction has been delivered to the Partnership by such Agent as provided in Section 2 below.

(c) Each Agent, as agent in any Agency Transaction, hereby covenants and agrees, severally and not jointly, not to make any sales of the Securities on behalf of the Partnership pursuant to this Agreement other than (i)(A) by means of ordinary brokers’ transactions between members of the Exchange that qualify for delivery of a Prospectus in accordance with Rule 153 under the Securities Act and meet the definition of an “at the market offering” under Rule 415(a)(4) under the Securities Act (such transactions are

hereinafter referred to as “At the Market Offerings”), (B) to or through a market maker, (C) directly on or through any other existing trading market or (D) by any other method permitted by law, including but not limited to in privately negotiated transactions and (ii) such other sales of the Securities on behalf of the Partnership in its capacity as agent of the Partnership as shall be agreed by the Partnership and such Agent in writing.

(d) If Securities are to be sold in an Agency Transaction in an At the Market Offering, the applicable Agent will confirm in writing to the Partnership the number of Securities sold on any Exchange Business Day and the related Gross Sales Price and Net Sales Price (as each of such terms is defined in Section 2(b) below) no later than the opening of trading on the immediately following Exchange Business Day.

(e) If the Partnership shall default on its obligation to deliver Securities to an Agent pursuant to the terms of any Agency Transaction or Terms Agreement, the Partnership shall (i) indemnify and hold harmless such Agent and its successors and assigns from and against any and all losses, claims, damages, liabilities and expenses arising from or as a result of such default by the Partnership and (ii) notwithstanding any such default, pay to such Agent the commission to which it would otherwise be entitled in connection with such sale in accordance with Section 2(b) below.

(f) The Partnership acknowledges and agrees that (i) there can be no assurance that an Agent will be successful in selling the Securities, (ii) no Agent shall incur any liability or obligation to the Partnership or any other person or entity if it does not sell Securities for any reason other than a failure by such Agent to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Securities in accordance with the terms of this Agreement, and (iii) no Agent shall be under any obligation to purchase Securities on a principal basis pursuant to this Agreement, except as may otherwise be specifically agreed by such Agent and the Partnership in a Terms Agreement.

2. Transaction Acceptances and Terms Agreements.

(a) The Partnership may, from time to time during the Term, propose to an Agent that they enter into an Agency Transaction to be executed on a specified Exchange Business Day or over a specified period of Exchange Business Days, which proposal shall be made to such Agent by telephone or by email from any of the individuals listed as an authorized representative of the Partnership on Schedule A hereto to make such sales and shall set forth the information specified below (each, a “Transaction Proposal”). If such Agent agrees to the terms of such proposed Agency Transaction or if the Partnership and such Agent mutually agree to modified terms for such proposed Agency Transaction, then such Agent shall promptly deliver to the Partnership by email a notice (each, a “Transaction Acceptance”) confirming the terms of such proposed Agency Transaction as set forth in such Transaction Proposal or setting forth the modified terms for such proposed Agency Transaction as agreed by the Partnership and such Agent, as the case may be, whereupon such Agency Transaction shall become a binding agreement between the Partnership and such Agent. Each Transaction Proposal shall specify:

(i) the Exchange Business Day(s) on which the Securities subject to such Agency Transaction are intended to be sold (each, a “Purchase Date”);

(ii) the maximum number of Securities to be sold by such Agent (the “Specified Number of Securities”) on, or over the course of, such Purchase Date(s), or as otherwise agreed between the Partnership and such Agent and documented in the relevant Transaction Acceptance;

(iii) the lowest price, if any, at which the Partnership is willing to sell Securities on each such Purchase Date or a formula pursuant to which such lowest price shall be determined (each, a “Floor Price”); and

(iv) if other than 2% of the Gross Sales Price, such Agent’s discount or commission.

A Transaction Proposal shall not set forth a Specified Number of Securities that, when added to the aggregate Gross Sales Price of Securities previously purchased and to be purchased pursuant to pending Transaction Acceptances (if any) hereunder and any Terms Agreements, results in a total aggregate Gross Sales Price that exceeds the Maximum Amount nor shall it set forth a Floor Price which is lower than the minimum price authorized from time to time by the Board of Directors of the General Partner. The Partnership shall have responsibility for maintaining records with respect to the aggregate Gross Sales Price of Securities sold and for otherwise monitoring the availability of Securities for sale under the Registration Statement and for insuring that the aggregate Gross Sales Price of Securities offered and sold does not exceed, and the price at which any Securities are offered or sold is not lower than, the Maximum Amount and the minimum price authorized from time to time by the Board of Directors of the General Partner, respectively. In the event that more than one Transaction Acceptance with respect to any Purchase Date(s) is delivered by the applicable Agent to the Partnership, the latest Transaction Acceptance shall govern any sales of Securities for the relevant Purchase Date(s), except to the extent of any action occurring pursuant to a prior Transaction Acceptance and prior to the delivery to the Partnership of the latest Transaction Acceptance. The Partnership or the applicable Agent may, upon notice to the other such party by telephone (confirmed promptly by e-mail), suspend or terminate the offering of the Securities pursuant to Agency Transactions for any reason; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Securities sold hereunder prior to the giving of such notice or their respective obligations under any Terms Agreement. Notwithstanding the foregoing, if the terms of any Agency Transaction contemplate that Securities shall be sold on more than one Purchase Date, then the Partnership and the applicable Agent shall mutually agree to such additional terms and conditions as they deem reasonably necessary in respect of such multiple Purchase Dates, and such additional terms and conditions shall be set forth in or confirmed by, as the case may be, the relevant Transaction Acceptance and be binding to the same extent as any other terms contained therein.

(b) The Purchase Date(s) in respect of the Securities deliverable pursuant to any Transaction Acceptance shall be set forth in or confirmed by, as the case may be, the applicable Transaction Acceptance. Except as otherwise agreed between the Partnership and an Agent in the applicable Transaction Acceptance, such Agent’s commission for any Securities sold through such Agent pursuant to this Agreement shall be a percentage, not to exceed 2%, of the actual sales price of such Securities (the “Gross Sales Price”); provided, however, that such commission shall not apply when an Agent acts as principal, in which case such commission or a discount shall be set forth in the applicable Terms Agreement. At each Agent’s election, such commission shall either be (i) invoiced in periodic statements from such Agent to the Partnership, with payment to be made by the Partnership promptly after its receipt thereof or (ii) deducted by the Agent from the payment of the Gross Sales Price to the Partnership. Notwithstanding the foregoing, in the event the Partnership engages an Agent for a sale of Securities in an Agency Transaction that would constitute a “distribution,” within the meaning of Rule 100 of Regulation M under the Exchange Act, or a “block,” within the meaning of Rule 10b 18(a)(5) under the Exchange Act, the Partnership will provide such Agent, at such Agent’s request and upon reasonable advance notice to the Partnership, on or prior to the Settlement Date (as defined in Section 2(g) below) the opinions and letters of counsel, accountants’ letters and officers’ certificates pursuant to Section 5 hereof, each dated the Settlement Date, and such other documents and information as such Agent shall reasonably request, and the Partnership and such Agent will agree to compensation that is customary for such Agent with respect to such transaction. The Gross Sales Price less the applicable Agent’s commission and after deduction for any transaction fees, transfer taxes or similar taxes or fees imposed by any governmental, regulatory or self-regulatory organization in respect of the sale of the applicable Securities is referred to herein at the “Net Sales Price.”

(c) Payment of the Net Sales Price for Securities sold by the Partnership on any Purchase Date pursuant to a Transaction Acceptance shall be made to the Partnership by wire transfer of immediately available funds to the account of the Partnership (which the Partnership shall provide to the applicable Agent at least one Exchange Business Day prior to the applicable Agency Settlement Date (as defined below)) against delivery of such Securities to such Agent’s account, or an account of such Agent’s designee, at The Depository Trust Company through its Deposit and Withdrawal at Custodian System (“DWAC”), or by such other means of delivery as may be agreed to by the Partnership and such Agent. Such payment and delivery shall be made at or about 10:00 a.m. (New York City time) on the third Exchange Business Day (or such other day as may, from time to time, become standard industry practice for settlement of such a securities issuance or as agreed to by the Partnership and such Agent) following each Purchase Date (each, an “Agency Settlement Date”).

(d) If, as set forth in or confirmed by, as the case may be, the related Transaction Acceptance, a Floor Price has been agreed to by the parties with respect to a Purchase Date, and the applicable Agent thereafter determines and notifies the Partnership that the Gross Sales Price for such Agency Transaction would not be at least equal to such Floor Price, then the Partnership shall not be obligated to issue and sell through such Agent, and such Agent shall not be obligated to place, the Securities

proposed to be sold pursuant to such Agency Transaction on such Purchase Date, unless the Partnership and such Agent otherwise agree in writing.

(e) If any party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Securities, it shall promptly notify the other parties and sales of the Securities under this Agreement, any Transaction Acceptance or any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the reasonable judgment of each party. On or prior to the delivery of a prospectus that is required (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) in connection with the offering or sale of the Securities, the Partnership shall calculate the average daily trading volume (as defined under “ADTV” by Rule 100 of Regulation M under the Exchange Act) of the LP Units based on market data provided by Bloomberg L.P. or such other sources as agreed upon by the Partnership and the applicable Agent.

(f) (i) If the Partnership wishes to issue and sell the Securities pursuant to this Agreement but other than as set forth in Section 2(a) of this Agreement, it will notify the applicable Agent of the proposed terms of the Principal Transaction. If such Agent, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Partnership, wishes to accept amended terms, the Partnership and such Agent shall enter into a Terms Agreement setting forth the terms of such Principal Transaction.

(ii) The terms set forth in a Terms Agreement shall not be binding on the Partnership or an Agent unless and until the Partnership and such Agent have each executed and delivered such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement shall control.

(g) Each sale of the Securities to an Agent in a Principal Transaction shall be made in accordance with the terms of this Agreement and a Terms Agreement, which shall provide for the sale of such Securities to, and the purchase thereof by, such Agent. A Terms Agreement may also specify certain provisions relating to the reoffering of such Securities by such Agent. The commitment of an Agent to purchase the Securities pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations, warranties and agreements of the Partnership contained, and shall be subject to the terms and conditions set forth, in this Agreement and such Terms Agreement. Any such Terms Agreement shall specify the number of the Securities to be purchased by the applicable Agent pursuant thereto, the price to be paid to the Partnership for such Securities, any provisions relating to rights of, and default by, underwriters, if any, acting together with such Agent in the reoffering of the Securities, and the time and date (each such time and date being referred to herein as a “Principal Settlement Date”; and, together with any Agency Settlement Date, a “Settlement Date”) and place of delivery of and payment for such Securities.

(h) Notwithstanding any other provision of this Agreement, the Partnership shall not offer, sell or deliver, or request the offer or sale, of any Securities pursuant to this Agreement (whether in an Agency Transaction or a Principal Transaction) and, by notice to each Agent given by telephone (confirmed promptly by email), shall cancel any instructions for the offer or sale of any Securities, and no Agent shall be obligated to offer or sell any Securities, (i) during any period in which the Partnership is, or could be deemed to be, in possession of material non-public information or (ii) at any time from and including the date on which the Partnership shall issue a press release containing, or shall otherwise publicly announce, its earnings, revenues or other results of operations (an “Earnings Announcement”) through and including the time that is 24 hours after the time that the Partnership files a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement.

(i) Notwithstanding clause (ii) of Section 2(h) hereof, if the Partnership wishes to offer, sell or deliver, or request the offer or sale, of any Securities to an Agent as agent at any time during the period from and including an Earnings Announcement through and including the time that the Partnership files a Quarterly Report on Form 10—Q or an Annual Report on Form 10—K that includes consolidated financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement, the Partnership shall first (i) prepare and deliver to each Agent (with a copy to counsel for the Agents) a Current Report on Form 8—K that includes substantially the same financial and related information (together with management’s discussion and analysis thereof) that was included in such Earnings Announcement (other than any earnings projections and similar forward-looking data and officers’ quotations) (each, an “Earnings 8—K”), in form and substance reasonably satisfactory to the Agents, and, prior to its filing, obtain the written consent of the Agents to such filing (which consent shall not be unreasonably withheld), (ii) provide the Agents with the officers’ certificate, opinions and letters of counsel and accountants’ letter specified in Section 6(b) through 6(d), inclusive, hereof, (iii) afford the Agents the opportunity to conduct a due diligence review in accordance with Section 6(f) hereof prior to filing such Earnings 8—K and (iv) file such Earnings 8—K with the Commission. For purposes of clarity, the parties hereto agree that (A) the delivery of any officers’ certificate, opinion or letter of counsel or accountants’ letter pursuant to this Section 2(i) shall not relieve the Partnership from any of its obligations under this Agreement with respect to any Quarterly Report on Form 10—Q or Annual Report on Form 10—K, as the case may be, including, without limitation, the obligation to deliver officers’ certificates, opinions and letters of counsel and accountants’ letters as provided in Section 6(b) through 6(d), inclusive, hereof and (B) this Section 2(i) shall in no way affect or limit the operation of clause (i) of Section 2(h) hereof, which shall have independent application.

(j) The Partnership agrees that any offer to sell, any solicitation of an offer to buy, or any sales of Securities by the Partnership shall be effected only by or through one Agent on any Exchange Business Day; provided, however, that the foregoing limitation shall apply only with respect to an Agency Transaction.

(k) Anything in this Agreement to the contrary notwithstanding, the Partnership shall not authorize the issuance and sale of, and no Agent, as agent, shall be obligated to use its commercially reasonable efforts, consistent with its normal trading and sales practices, to sell, any Securities at a price lower than the then-applicable minimum price, or in a number with an aggregate Gross Sales Price in excess of the Maximum Amount authorized from time to time to be issued and sold under this Agreement and any Terms Agreements, in each case by the Board of Directors of the General Partner, or in a number in excess of the number of Securities approved for listing on the Exchange, or with an aggregate Gross Sales Price in excess of the maximum offering price for the Securities available for issuance on the Registration Statement or as to which the Partnership has paid the applicable registration fee, it being understood and agreed by the parties hereto that compliance with any such limitations shall be the sole responsibility of the Partnership.

3. Representations, Warranties and Agreements of the Partnership and the General Partner. The Partnership and the General Partner severally and jointly represent and warrant to, and agree with, each Agent, unless otherwise specified, on and as of (i) the date of this Agreement, (ii) each date on which the Partnership receives a Transaction Acceptance (the “Time of Acceptance”), (iii) each date on which the Partnership executes and delivers a Terms Agreement, (iv) each Time of Sale (as defined in Section 3(a)), (v) each Settlement Date and (vi) each Bring-Down Delivery Date (as defined in Section 6(b)) (each such date listed in (i) through (vi), a “Representation Date”), as follows:

(a) The Registration Statement has been filed with the Commission and declared effective; there is no order preventing or suspending the use of the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus, and, to the knowledge of the Partnership, no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Partnership or related to the offering of the Securities has been initiated or threatened by the Commission; the Registration Statement complied when it initially became effective, complies as of the date of this Agreement, as then amended or supplemented, as of each other Representation Date will comply, in all material respects, with the requirements of the Securities Act; the conditions to the use of Form S-3 in connection with the offering and sale of the Securities as contemplated hereby have been satisfied; the Registration Statement meets, and the offering and sale of the Securities as contemplated hereby comply with, the requirements of Rule 415 under the Securities Act (including, without limitation, Rule 415(a)(5)); the Prospectus complied or will comply, at the time it was or will be filed with the Commission, and will comply, as then amended or supplemented, as of each Representation Date, in all material respects, with the requirements of the Securities Act; the Registration Statement did not, as of the time of its initial effectiveness, and does not or will not, as then amended or supplemented, as of each Representation Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; as of each Representation Date, the Prospectus, as then amended or supplemented, together with all of the then issued Permitted Free Writing Prospectuses, if any, will not contain an 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; provided, however, that

neither the Partnership nor the General Partner makes any representation or warranty with respect to any statement in or omission from the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus made in reliance upon and in conformity with information concerning the Agents and furnished in writing by or on behalf of the Agents expressly for use in the Registration Statement, the Prospectus or such Permitted Free Writing Prospectus (it being understood that as of the date hereof such information consists solely of the information specified in Section 9(b)). As used herein, “Time of Sale” means (i) with respect to each offering of Securities pursuant to this Agreement, the time of the Agent’s initial entry into contracts with investors for the sale of such Securities and (ii) with respect to each offering of Securities pursuant to any relevant Terms Agreement, the time of sale of such Securities.

(b) Prior to the execution of this Agreement, the Partnership has not, directly or indirectly, offered or sold any of the Securities by means of any “prospectus” (within the meaning of the Securities Act) or used any “prospectus” (within the meaning of the Securities Act) in connection with the offer or sale of the Securities, in each case other than the Basic Prospectus. The Partnership represents and agrees that, unless it obtains the prior consent of the Agents, until the termination of this Agreement, it has not made and will not make any offer relating to the Securities that would constitute an “issuer free writing prospectus” (as defined in Rule 433 under the Securities Act) or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Securities Act) other than any Permitted Free Writing Prospectus. Any such free writing prospectus relating to the Securities consented to by the Agents (including any Free Writing Prospectus prepared by the Partnership solely for use in connection with the offering contemplated by a particular Terms Agreement) is hereinafter referred to as a “Permitted Free Writing Prospectus”. The Partnership has complied and will comply in all material respects with the requirements of Rule 433 under the Securities Act applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping. The conditions set forth in one or more of subclauses (i) through (iv), inclusive, of Rule 433(b)(1) under the Securities Act are satisfied, and the registration statement relating to the offering of the Securities contemplated hereby, as initially filed with the Commission, includes a prospectus that, other than by reason of Rule 433 under the Securities Act, satisfies the requirements of Section 10 of the Securities Act; the Partnership is not disqualified, by reason of Rule 164(f) or (g) under the Securities Act, from using, in connection with the offer and sale of the Securities, “free writing prospectuses” (as defined in Rule 405 under the Securities Act) pursuant to Rules 164 and 433 under the Securities Act. The Partnership has paid the registration fee for the offering of the Maximum Amount of Securities pursuant to Rule 457 under the Securities Act.

(c) The Incorporated Documents, when they were filed with the Commission (or, if any amendment with respect to any such document was filed, when such amendment was filed), conformed in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and none of such documents contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and any further documents

so filed during the Term and incorporated by reference in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Each of the General Partner, the Partnership, and the subsidiaries of the Partnership have been duly formed and is validly existing as a corporation, limited liability company, limited partnership, or other entity under the laws of the jurisdiction of its organization, has the corporate, limited liability company, limited partnership or analogous, as applicable, power and authority to own or lease, as the case may be, and to operate its properties and conduct its business in all material respects as described in the Registration Statement and the Prospectus and, with respect to the General Partner, to act as the general partner of the Partnership. Each of the General Partner, the Partnership, and the subsidiaries of the Partnership is duly qualified or registered to do business as a foreign corporation, limited liability company, limited partnership or other entity in, and is in good standing under the laws of, each jurisdiction where the ownership or leasing of its properties or the conduct of its business requires such qualification or registration, except where the failure to be so qualified or registered and in good standing would not, individually or in the aggregate, (i) have a material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of the Partnership and the Partnership’s subsidiaries (collectively, the “Partnership Entities”), taken as a whole, whether or not arising from transactions in the ordinary course of business or (ii) subject the Partnership or the limited partners of the Partnership to any material liability or disability, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Prospectus (exclusive of any supplement thereto) ((i) or (ii), a “Material Adverse Effect”).

(e) The General Partner is the sole general partner of the Partnership, with a noneconomic general partner interest in the Partnership; such general partner interest is the only general partner interest of the Partnership that is issued and outstanding; and such general partner interest has been duly authorized and validly issued and is owned by the General Partner free and clear of any perfected security interest or any other security interest, claim, lien or encumbrance (collectively, “Liens”).

by filing documents pursuant to the Securities Act, the Exchange Act or otherwise, as may be necessary to correct such untrue statement or omission or to make the Prospectus or any such Permitted Free Writing Prospectus comply with such requirements and, if at any time during the Term it shall be necessary, in the reasonable opinion of either such counsel, to amend or supplement the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus in order to comply with the requirements of the Securities Act, in the case of such a determination by counsel to the Partnership, immediate notice shall be given, and confirmed in writing, to the Agents to cease the solicitation of offers to purchase the Securities in the Agents’ capacity as agents and the Partnership will, subject to Section 4(a) above, promptly prepare and file with the Commission such amendment or supplement, whether by filing documents pursuant to the Securities Act, the Exchange Act or otherwise, as may be necessary to make the Registration Statement, the Prospectus or any such Permitted Free Writing Prospectus comply with such requirements.

(c) Subject to Section 6(h), on each Bring-Down Delivery Date, the Partnership shall, unless the Agents agree otherwise, cause to be furnished to Agents the written opinion and, if not included in such opinion, negative assurance letter of ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, counsel to the Partnership, dated as of the applicable Bring-Down Delivery Date and delivered within three Exchange Business Days after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, dated and delivered on such Principal Settlement Date, of the same tenor as the opinion and letter referred to in Section 5(a)(ii) hereof, as applicable, but modified as necessary to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the time of delivery of such opinions and letters, or, in lieu of such opinion and letter, such counsel shall furnish the Agents with a letter substantially to the effect that the Agents may rely on the opinion and letter of such counsel referred to in Section 5(a)(ii), furnished to the Agents, to the same extent as though they were dated the date of such letter authorizing reliance (except that statements in such last opinion and letter of such counsel shall be deemed to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the time of delivery of such letters authorizing reliance).

(d) Subject to Section 6(h), on each Bring-Down Delivery Date, the Partnership shall, unless the Agents agree otherwise, cause the Partnership’s independent accountants to furnish to the Agents a “comfort” letter, dated as of the applicable Bring-Down Delivery Date and delivered within three Exchange Business Days after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, delivered on such Principal Settlement Date, of the same tenor as the letter referred to in Section 5(a)(iv) hereof, but modified to relate to the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus as amended and supplemented to the date of such letter, and, if the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus shall include or incorporate by reference the financial statements of any entity or business (other than the consolidated financial statements of the Partnership and its subsidiaries), the Partnership shall, if requested by the Agents, cause a firm of independent public accountants to furnish to the Agents a “comfort” letter, dated as of the applicable Bring-Down Delivery Date and delivered within three Exchange Business Days after the applicable Bring-Down Delivery Date or, in the case of a Bring-Down Delivery Date resulting from a Principal Settlement Date, delivered on such Principal Settlement Date, addressing such matters as the Agents may reasonably request.

(e) (i) No order suspending the effectiveness of the Registration Statement shall be in effect, and no proceeding for such purpose or pursuant to Section 8A under the Securities Act shall be pending before or threatened by the Commission; the Prospectus and each Permitted Free Writing Prospectus shall have been timely filed with the Commission under the Securities Act (in the case of a Permitted Free Writing Prospectus, to the extent required by Rule 433 under the Securities Act); and all requests by the Commission for additional information shall have been complied with to the reasonable satisfaction of the Agents and no suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes, shall have occurred and be in effect at the time the Partnership delivers a Transaction Proposal to an Agent or the time an Agent delivers a Transaction Acceptance to the Partnership; and (ii) the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus shall not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading at the time the Partnership delivers a Transaction Proposal to an Agent or the time an Agent delivers a Transaction Acceptance to the Partnership.

such prospectus supplement, such shorter period as the Agents may reasonably request or, in the case of an Annual Report on Form 10-K, during the fiscal year covered by such Annual Report and the fourth quarter of such fiscal year.

(h) The requirements (i) to provide the officers’ certificate, opinions and letters of counsel and accountants’ letter specified in Section 6(b) through 6(d) and (ii) to reasonably cooperate with any reasonable due diligence review specified in Section 6(f) shall be waived for any Bring-Down Delivery Date occurring at a time at which no Transaction Proposal or offers to enter into a Terms Agreement is pending, which waiver shall continue until the earlier to occur of the date the Partnership delivers a Transaction Proposal or offers to enter into a Terms Agreement hereunder (which for such calendar quarter shall be considered a Bring-Down Delivery Date) and the next occurring Bring-Down Delivery Date.

All opinions, letters and other documents referred to in Sections 6(b) through 6(d) above shall be reasonably satisfactory in form and substance to the Agents. The Agents will provide the Partnership with such notice (which may be oral, and in such case, will be confirmed via e-mail as soon as reasonably practicable thereafter) as is reasonably practicable under the circumstances when requesting an opinion, letter or other document referred to in Sections 6(b) through 6(d) above.

(v) Subsequent to the relevant Time of Acceptance or, in the case of a Principal Transaction, subsequent to execution of the applicable Terms Agreement, (A) no downgrading shall have occurred in the rating accorded any debt securities of or guaranteed by the Partnership or any of its subsidiaries by any “nationally recognized statistical rating organization”, as such term is defined by the Commission for purposes of Section 3(a)(62) of the Exchange Act and (B) no such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its rating of any debt securities of or guaranteed by the Partnership or any of its subsidiaries (other than an announcement with positive implications of a possible upgrading) in each case that has not been described in the Prospectus prior to any related Time of Sale.

(b) Each Agent agrees, severally and not jointly, to indemnify and hold harmless the Partnership, the General Partner and each of its directors and officers who signed the Registration Statement and each person, if any, who controls the Partnership or the General Partner within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to the Agents furnished to the Partnership in writing by the Agents expressly for use in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto) or any Permitted Free Writing Prospectus (or any amendment or supplement thereto) or any road show, it being understood and agreed upon that (except as may be agreed in writing between all parties after the date of this Agreement) such information shall consist solely of the following: the information appearing in the last sentence of the second paragraph under the caption “Plan of Distribution” in the Prospectus Supplement.

(c) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either Section 9(a) or 9(b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under this Section 9 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and

provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under this Section 9. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 9 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary or (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) included both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm (in addition to any local counsel) for (A) the Agents and their affiliates, directors and officers and their control persons, if any, or (B) the Partnership, the General Partner and each of its directors and officers who signed the Registration Statement and its control persons, if any, as the case may be, and that all such reasonable fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for the Agents and their affiliates, directors and officers and their control persons, if any, shall be designated in writing by the Agents, and any such separate firm for the Partnership, the General Partner and each of its directors and officers who signed the Registration Statement and its control persons, if any, shall be designated in writing by the Partnership. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification is or could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act, by or on behalf of any Indemnified Person. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this Section 9(c), the Indemnifying

Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request and (ii) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement.

(d) If the indemnification provided for in Sections 9(a) or 9(b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such Sections, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership, on the one hand, and the applicable Agents, on the other, from the offering of the Securities pursuant to this Agreement and any Terms Agreements or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Partnership, on the one hand, and the applicable Agents, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Partnership, on the one hand, and the applicable Agents, on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Partnership from the sale of the Securities pursuant to this Agreement and any Terms Agreements and the total discounts and commissions received by the applicable Agents in connection therewith bear to the aggregate Gross Sales Price of such Securities. The relative fault of the Partnership, on the one hand, and the applicable Agents, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership, on the one hand, or by the applicable Agents, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Partnership and the Agents agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in Section 9(d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in Section 9(d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 9, in no event shall an Agent be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Agent with respect to the offering of the Securities pursuant to this Agreement and any Terms Agreements exceeds the amount of any damages that such Agent has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act)

shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

The Partnership acknowledges and agrees that each Agent is acting solely in the capacity of an arm’s length contractual counterparty to the Partnership with respect to the offering of Securities contemplated hereby and any Terms Agreements (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Partnership or any other person. Additionally, no Agent is advising the Partnership or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Partnership shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and no Agent shall have responsibility or liability to the Partnership with respect thereto. Any review by the Agents of the Partnership, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Agents and shall not be on behalf of the Partnership.

Nothing in this Agreement or any Terms Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any such Terms Agreement or any provision contained herein or therein. No purchaser of Securities from or through an Agent shall be deemed to be a successor merely by reason of purchase.

15. Counterparts. This Agreement and any Terms Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

16. Survival.
