(c) Promptly after receipt by an indemnified party under this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Representative shall have the right to employ counsel to represent jointly the Representative and those other Underwriters and their respective officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Magellan Parties under this Section 7 if, in the reasonable judgment of the Representative, it is advisable for the Representative and those Underwriters, officers, employees and controlling persons to be jointly represented by separate counsel, and in that event the fees and expenses of one such separate counsel (plus one local counsel if necessary) shall be paid by the Magellan Parties. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any

indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 7 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or 7(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Magellan Parties, on the one hand, and the Underwriters on the other, 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 Magellan Parties, on the one hand, and the Underwriters on the other, with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Magellan Parties, on the one hand, and the Underwriters on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under this Agreement (before deducting expenses) received by the Magellan Parties, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Notes purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Notes under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to 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 or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Magellan Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7 were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which 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, damage or liability, or action in respect thereof, referred to above in this Section 7 shall be deemed to include, for purposes of this Section 7(d), 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 7(d), 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 was offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any 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 Underwriters’ obligations to contribute as provided in this Section 7(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Magellan Parties acknowledge that the table of underwriters on page S-43, the second and sixth paragraphs under the table of underwriters on page S-43, the last two sentences of the first paragraph on page S-44, the third

and fourth sentences of the third paragraph on page S-44, and the fifth, seventh and eighth paragraphs on page S-44, all under the caption “Underwriting” in the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Partnership by or on behalf of the Underwriters specifically for inclusion in the Registration Statement and the Prospectus.

Section 8. Defaulting Underwriters.

If, on the Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Notes that the defaulting Underwriter agreed but failed to purchase on the Delivery Date in the respective proportions which the principal amount of the Notes set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total principal amount of Notes set opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Notes on the Delivery Date if the total principal amount of the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the aggregate principal amount of Notes to be purchased on the Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the total principal amount of Notes which it agreed to purchase on the Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representative who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, the total aggregate principal amount of the Notes to be purchased on the Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representative do not elect to purchase the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on the Delivery Date, in accordance with the first sentence of this Section 8, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Magellan Parties, except that the Magellan Parties will continue to be liable for the payment of expenses to the extent set forth in Sections 5 and 10. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 8, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Magellan Parties for damages, including expenses paid by the Partnership pursuant to Sections 5 and 10, caused by its default. If other underwriters are obligated or agree to purchase the Notes of a defaulting or withdrawing Underwriter, either the Representative or the Partnership may postpone the Delivery Date for up to seven (7) full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

Section 9. Termination.

The obligations of the Underwriters hereunder may be terminated by the Representative by notice given to and received by the Partnership prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 6(j), 6(k), or 6(l) shall have occurred

or if the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement.

Section 10. Reimbursement of Underwriters’ Expenses.

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 any of the Magellan Parties to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by any of the Magellan Parties is not fulfilled, the Magellan Parties will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Magellan Parties shall pay the full amount thereof to the Representative. If this Agreement is terminated pursuant to Section 9 hereof by reason of the default of one or more Underwriters, the Magellan Parties shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

Section 11. Notices.

All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to each of Xxxxxx Brothers Inc., Syndicate Registration Department, 0000 Xxxxxx xx xxx Xxxxxxxx, 00^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, (Fax: 000-000-0000), with a copy, in the case of any notice pursuant to Section 7(c), to the Director of Litigation, Office of the General Counsel, Xxxxxx Brothers Inc., 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000;

provided, however, that any notice to an Underwriter pursuant to Section 7(c) shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its acceptance telex to the Representative, which address will be supplied to any other party hereto by the Representative upon request. Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Magellan Parties shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Underwriters by the Representative and the Underwriters shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Magellan Parties.

Section 12. Persons Entitled to Benefit of Agreement.

This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Magellan Parties and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the Magellan Parties contained in this Agreement shall also be deemed to be for the benefit of the person or persons, if any, who control any Underwriter within the meaning of Section 15 of the Securities Act and (B) the indemnity agreement of the Underwriters contained in Section 7(b) of this Agreement shall be deemed to be for the benefit of directors of the General Partner, the officers of the General Partner who have

signed the Registration Statement and any person controlling the General Partner within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 12, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

Section 13. Survival.

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

Section 14. Definition of the Terms “Business Day” and “Subsidiary”.

For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “subsidiary” and “affiliate” have their respective meaning set forth in Rule 405 of the Rules and Regulations.

Section 15. Governing Law.

THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

Section 16. Counterparts.

This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

Section 17. Headings.

The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

(xviii) The statements contained in the Prospectus under the captions “Cash Distributions,” “Material Tax Consequences,” “United States Federal Income Tax Considerations” and “Investment in Us by Employee Benefit Plans,” insofar as they constitute descriptions of contracts or legal proceedings or refer to statements of law or legal conclusions, are accurate and complete in all material respects, and the Notes conform in all material respects to the descriptions thereof contained in the Prospectus under the captions “Summary—The Offering,” “Description of Notes” and “Description of Debt Securities.”

(xix) The Registration Statement was declared effective under the Securities Act as of the date and time specified in such opinion, the Prospectus was filed with the Commission pursuant to the subparagraph of Rule 424(b) of the Rules and Regulations specified in such opinion on the date specified therein and no stop order suspending the effectiveness of the Registration Statement has been issued and, to the knowledge of such counsel, no proceeding for that purpose is pending or threatened by the Commission.

(xxii) Neither the General Partner nor any member of the Partnership Group is an “investment company” as defined in the Investment Company Act of 1940, as amended.

Since such counsel has not conducted any independent investigation or verification with regard to the information set forth in the Registration Statement or Prospectus (except with respect to the opinions set forth herein), such counsel is not (except as aforesaid) passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained therein. Such counsel has participated, however, in conferences with officers and other representatives of the Partnership Entities, representatives of the independent public accountants of the Partnership and the Underwriters’ Representative, at which the contents of the Registration Statement and Prospectus and related matters were discussed. Based on the foregoing (relying as to factual matters in respect of the determination of materiality to a significant extent upon the statements of fact made by officers and other representatives of the Partnership Entities), no facts have come to such counsel’s attention that have led such counsel to believe that the Registration Statement, at the time such Registration Statement became effective, 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 not misleading or that, as of its date, the Prospectus contained an untrue statement of a material fact or omitted a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or that, as of the date hereof, the Prospectus contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Such counsel, however, expresses no opinion with respect to the financial statements and notes and related schedules and other related financial, accounting and statistical data included in the Registration Statement or in the Prospectus or any further amendment or supplement thereto or with respect to the Form T-1 of the Trustee.

Such counsel’s opinion may be limited to matters governed by the federal laws of the United States of America, the laws of the State of Texas, the laws of the State of New York, the DGCL, the Delaware LP Act and the Delaware LLC Act. Such counsel need not express any opinion with respect to the title of any members of the Partnership Group to any of their respective real or personal property or the accuracy of the descriptions or references in the Registration Statement to any real or personal property, and need not express any opinion with respect to state or local taxes or tax statutes to which any of the limited partners of the Partnership or any members of the Partnership Group may be subject. Any references herein to such counsel’s knowledge shall mean the actual knowledge of such counsel’s attorneys
