Ladies and Gentlemen:

Magellan Midstream Partners, L.P., a Delaware limited partnership (the “Partnership”), proposes to issue and sell to the several underwriters named in Schedule I hereto (collectively, the “Underwriters”) $500 million aggregate principal amount of its 4.850% Senior Notes due 2049 (the “Notes”) to be issued pursuant to the terms of an indenture (the “Original Indenture”) between the Partnership and U.S. Bank National Association, as trustee (the “Trustee”), dated as of August 11, 2010, as amended and supplemented by the Ninth Supplemental Indenture for the Notes, to be dated as of January 18, 2019 (the “Supplemental Indenture”). The Original Indenture, as so amended and supplemented, is referred to herein as the “Indenture.”

The Partnership has filed with the Securities and Exchange Commission (the “Commission”) a registration statement (File No. 333-223097), including a prospectus, on Form S-3 relating to the securities (the “Shelf Securities”), including the Notes, to be issued from time to time by the Partnership. The registration statement as amended to the date of this Underwriting Agreement (this “Agreement”), including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or Rule 430B under the Securities Act of 1933, as amended (the “Securities Act”), is hereinafter referred to as the “Registration Statement,” and the related prospectus covering the Shelf Securities dated February 20, 2018 in the form first used to confirm sales of the Notes (or in the form first made available to the Underwriters by the Partnership to meet requests of purchasers pursuant to Rule 173 of the Rules and Regulations (as defined below)) is hereinafter referred to as the “Base Prospectus.” The term “Effective Date” means any date as of which any part of the Registration Statement relating to the Shelf Securities became, or is deemed to have become, effective under the Securities Act in accordance with the rules and regulations (the “Rules and Regulations”) of the Commission thereunder. The Base Prospectus, as supplemented by the prospectus supplement specifically relating to the Notes in the form first used to confirm sales of the Notes (or in the form first made available to the Underwriters by the Partnership to meet requests of purchasers pursuant to Rule 173 of the Rules and Regulations) is hereinafter referred to as the “Prospectus,” and the term “preliminary prospectus” means any preliminary form of the Prospectus. For purposes of this Agreement, “Issuer Free Writing Prospectus” means each “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) prepared by or on behalf of the Partnership or used or referred to by the Partnership in connection with the offering of the Notes and “broadly available road show” means a “bona fide electronic road show” as defined in Rule 433(h)(5) of the Rules and Regulations that has been made available without restriction to any person.

At or prior to the time when sales of the Notes were first made (the “Time of Sale”), the Partnership had prepared the following information (collectively, the “Time of Sale Prospectus”): the preliminary prospectus, together with each free writing prospectus identified in Schedule II hereto.

As used herein, the terms “Registration Statement,” “preliminary prospectus,” “Base Prospectus,” “Time of Sale Prospectus” and “Prospectus” shall include the documents, if any, incorporated by reference therein. The terms “supplement,” “amendment” and “amend” as used herein with respect to the Registration Statement, the Base Prospectus, the Time of Sale Prospectus or any free writing prospectus shall include all documents subsequently filed by the Partnership with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are deemed to be incorporated by reference therein.

This Agreement is to confirm the agreement among the Partnership and the Underwriters concerning the purchase of the Notes from the Partnership by the Underwriters.

1. Representations, Warranties and Agreements of the Partnership. The Partnership represents and warrants to, and agrees with, each Underwriter that:

(a) Effectiveness of Registration Statement. The Registration Statement relating to the Notes (i) has been prepared by the Partnership in conformity with the requirements of the Securities Act and the Rules and Regulations; (ii) has been filed with the Commission under the Securities Act; and (iii) is effective under the Securities Act. Copies of such registration statement and any amendments thereto have been delivered by the Partnership to the Underwriters.

(b) Well-Known Seasoned Issuer. The Partnership was, (i) at the time of filing of the Registration Statement and (ii) at the time of the most recent amendment thereto (whether by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act, or form of prospectus) for purposes of complying with Section 10(a)(3) of the Securities Act (or, if any such amendment was not made within the time period required by Section 10(a)(3) of the Securities Act, at the date on which such amendment was required), a “well-known seasoned issuer” (as defined in Rule 405 of the Rules and Regulations). The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405 of the Rules and Regulations) and was not filed earlier than the date that is three years prior to the Closing Date (as defined in Section 4 hereof). The Partnership was not at the time of filing of the Registration Statement and at the earliest time thereafter that the Partnership or another offering participant made a bona fide offer (within the meaning of Rule 164 of the Rules and Regulations) of the Notes, and will not be on the Closing Date, an “ineligible issuer” (as defined in Rule 405 of the Rules and Regulations).

(c) Conformity to Securities Act. The Registration Statement conformed and will conform in all material respects on the Effective Date and on the Closing Date, and any amendment to the Registration Statement filed after the date hereof will conform in all material respects when filed with the Commission, to the requirements of the Securities Act and the Rules and Regulations. The Time of Sale Prospectus conformed, and the Prospectus will conform in all material respects when filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations and on the Closing Date to the requirements of the Securities Act and the Rules and Regulations. The documents incorporated by reference in the Registration Statement, the Time of Sale Prospectus or the Prospectus conformed or will conform, when filed with the Commission in all material respects, to the requirements of the Exchange Act or the Securities Act, as applicable, and the rules and regulations of the Commission thereunder. The Partnership has not received from the Commission any notice pursuant to Rule 401(g)(2) of the Rules and Regulations objecting to the use of the automatic shelf registration statement form.

(d) Misleading Statements – Registration Statement. The Registration Statement did not, as of the Effective 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; and each of the statements made by the Partnership in the Registration Statement and any further amendments to the Registration Statement within the coverage of Rule 175(b) of the Rules and Regulations was made with a reasonable basis and in good faith; provided that no representation or warranty is made as to information contained in or omitted from the Registration Statement in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of the Underwriters specifically for inclusion therein, which information is specified in Section 8(b).

(e) Misleading Statements – Prospectus. The Prospectus will not, as of its date and on the Closing Date, contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and each of the statements made or to be made by the Partnership in the preliminary prospectus or the Prospectus, as applicable, and any further supplements to the preliminary prospectus or the Prospectus within the coverage of Rule 175(b) of the Rules and Regulations was made with a reasonable basis and in good faith; provided that no representation or warranty is made as to information contained in or omitted from the Prospectus in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of the Underwriters specifically for inclusion therein, which information is specified in Section 8(b).

(f) Misleading Statements – Documents Incorporated by Reference. The documents incorporated by reference in the Registration Statement, the Time of Sale Prospectus or the Prospectus did not, and any further documents filed and incorporated by reference therein will not, when filed with the Commission and on the Closing 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, in the light of the circumstances under which they were made, not misleading.

(g) Misleading Statements – Time of Sale Prospectus. The Time of Sale Prospectus did not, as of the Time of Sale, 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, in the light of the circumstances under which they were made, not misleading; provided that no representation or warranty is made as to information contained in or omitted from the Time of Sale Prospectus in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of the Underwriters specifically for inclusion therein, which information is specified in Section 8(b).

(h) Misleading Statements – Free Writing Prospectuses. Each Issuer Free Writing Prospectus (including, without limitation, any road show that is a free writing prospectus under Rule 433 of the Rules and Regulations), when considered together with the Time of Sale Prospectus as of the Time of Sale, did not contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that the price of the Notes and disclosures directly relating thereto will be included in the Prospectus.

(i) Free Writing Prospectuses. Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Securities Act and the Rules and Regulations on the date of first use, and the Partnership has complied with all prospectus delivery requirements and any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to the Rules and Regulations. The Partnership has not made any offer relating to the

Notes that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Managers. The Partnership has retained in accordance with the Rules and Regulations all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Rules and Regulations. Each Issuer Free Writing Prospectus, as of the date of first use and at all subsequent times through the completion of the public offer and sale of the Notes or until any earlier date that the Partnership notified or notifies the Managers as described in Section 5(a)(vi), did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement, including any document incorporated therein by reference and any prospectus supplement deemed to be a part thereof that has not been superseded or modified.

Each of the Partnership and its Subsidiaries owns or leases or has such other valid and enforceable rights to use all such assets and properties as are necessary to the conduct of its business and operations as described in the Time of Sale Prospectus and the Prospectus or as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, except as are described in the Time of Sale Prospectus and the Prospectus; provided that, with respect to pipeline rights-of-way, the Partnership represents only that neither the Partnership nor any Subsidiary has received any actual notice or claim from any owner of land upon which its pipeline is located (i) that any of such entities, as applicable, does not have sufficient title to enable it to use and occupy the pipeline rights-of-way as they are used and occupied as described in the Time of Sale Prospectus and the Prospectus, (ii) which constitute valid claims that have not been satisfied by the applicable parties and (iii) that would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(bb) Permits. The Partnership and each of its Subsidiaries possess all licenses, certificates, permits and other authorizations issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct its respective businesses, except where the failure to possess such licenses, certificates, permits and other authorizations would not, individually or in the aggregate, have a Material Adverse Effect, and neither the Partnership nor any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such license, certificate, authorization or permit which, if the subject of an unfavorable decision, ruling or finding, would have, individually or in the aggregate, a Material Adverse Effect, except as set forth in or contemplated in the Time of Sale Prospectus and the Prospectus.

In any such proceeding, any indemnified party 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 party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in

the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Managers, in the case of parties indemnified pursuant to Section 8(a), and by the Partnership, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party 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 party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (A) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (B) 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) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party 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 Underwriters on the other hand from the offering of the Notes or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership on the one hand and of the Underwriters on the other hand 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 Underwriters on the other hand in connection with the offering of the Notes shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Notes (before deducting expenses) received by the Partnership and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate public offering price of the Notes. The relative fault of the Partnership on the one hand and the Underwriters on the other hand 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 or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Notes they have purchased hereunder, and not joint.

(e) The Partnership and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 8(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter 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. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

9. Effectiveness; Default by an Underwriter. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase the Notes that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Notes to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Notes set forth opposite their respective names in Schedule I bears to the aggregate number of Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Notes that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such number of Notes without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase the Notes and the aggregate number of Notes with respect to which such default occurs is more than one-tenth of the aggregate number of Notes to be purchased on such date, and arrangements satisfactory to you and the Partnership for the purchase of such Notes are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Partnership. In any such case either you or the Partnership shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If the Partnership shall fail to tender the Notes for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Partnership to perform any agreement on its part to be performed, or because any other condition to the Underwriters’ obligations hereunder required to be fulfilled by the Partnership is not fulfilled for any reason or the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement, then, except as specified in the following sentence, the Partnership will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by Underwriters in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Partnership shall pay the full amount thereof to the Underwriters. If this Agreement is terminated (i) pursuant to Section 10 because of the occurrence of any event specified in Section 10 (other than as specified in Section 10(ii)), the Partnership shall not be obligated to reimburse the Underwriters for any expenses specified in the immediately preceding sentence or (ii) pursuant to this Section 9 by reason of the default of one or more Underwriters, the Partnership shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

10. Termination. The Underwriters may terminate this Agreement by notice given by the Managers to the Partnership, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange or the NASDAQ Global Market, (ii) trading of any securities of the Partnership shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Notes on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

11. Research Analyst Independence. The Partnership acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of their respective investment banking divisions. The Partnership hereby waives and releases, to the fullest extent permitted by law, any claims that the Partnership may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Partnership by the Underwriters’ investment banking divisions. The Partnership acknowledges that each Underwriter is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of any of the Partnership Entities.

12. Entire Agreement.

(a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Notes, represents the entire agreement between the Partnership and the Underwriters with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Notes.

(b) The Partnership acknowledges that in connection with the offering of the Notes: (i) the Underwriters have acted at arms length, are not agents of, and owe no fiduciary duties to, the Partnership or any other person, (ii) the Underwriters owe the Partnership only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Partnership. The Partnership waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Notes.

13. Notices, Etc. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters, shall be delivered, mailed or sent in care of X.X.

14. Survival. The respective indemnities, representations, warranties and agreements of the Partnership and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement or any certificate delivered pursuant hereto, shall survive the delivery of and payment for the Notes and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or investigation made by or on behalf of any of them or any person controlling any of them.

15. Governing Law. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement, directly or indirectly, shall be governed by and construed in accordance with the laws of the State of New York.

16. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Facsimile copies or “pdf” or similar electronic data format copies of signatures shall constitute original signatures for all purposes of this Agreement and any enforcement hereof.

17. Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Partnership, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

18. Jurisdiction; Venue. The parties hereby consent to (i) nonexclusive jurisdiction in the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, (ii) nonexclusive personal service with respect thereto, and (iii) personal jurisdiction, service and venue in any court in which any claim arising out of or in any way relating to this Agreement is brought by any third party against the Underwriters or any indemnified party. Each of the parties (on its behalf and, to the extent permitted by applicable law, on behalf of its limited partners and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The parties agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the parties and may be enforced in any other courts to the jurisdiction of which the parties is or may be subject, by suit upon such judgment.

19. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

20. Recognition of the U.S. Special Resolution Regimes.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate (as defined in this Section 20) of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights (as defined in this Section 20) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

*	Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

It is expected that delivery of the notes will be made to investors on or about January 18, 2019, which will be the fifth business day following the date hereof (such settlement being referred to as “T+5”). Under Rule 15c6-1 under the Securities and Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the second business day prior to delivery of the notes hereunder may be required, by virtue of the fact that the notes initially settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and such purchasers should consult their own advisors.

The issuer has filed a registration statement (including a preliminary prospectus supplement and a prospectus) with the U.S. Securities and Exchange Commission (the “SEC”) for the offering to which this communication relates. Before you invest, you should read the preliminary prospectus supplement, the issuer’s prospectus in that registration statement and any other documents the issuer has filed with the SEC for more complete information about the issuer and this offering. You may get these documents for free by visiting XXXXX on the SEC web site at xxxx://xxx.xxx.xxx. Alternatively, the issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus supplement and prospectus if you request it by calling X.X. Xxxxxx Securities LLC at 0-000-000-0000, Mizuho Securities USA LLC at 1-866-271-7403, RBC Capital Markets, LLC at 0-000-000-0000, SMBC Nikko Securities America, Inc. at 0-000-000-0000 or U.S. Bancorp Investments, Inc. at 0-000-000-0000.
