Each date and time the Option Units are delivered is sometimes referred to as a “Second Delivery Date” and the First Delivery Date and any Second Delivery Date are sometimes each referred to as a “Delivery Date.”

Delivery of the Option Units by the Partnership and payment for the Option Units by the several Underwriters through the Representative shall be made at the place specified in the first sentence of the first paragraph of this Section 4 (or at such other place as shall be determined by

agreement between the Representative and the Partnership) beginning at 8:30 a.m., Houston, Texas time, on such Second Delivery Date.

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 8 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, directors, 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 Partnership Parties under this Section 8 if, (i) the Partnership Parties and the Underwriters shall have so mutually agreed; (ii) the Partnership Parties have failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriters; (iii) the Underwriters and their respective directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the Partnership Parties; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriters or their respective directors, officers, employees or controlling persons, on the one hand, and the Partnership Parties, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Partnership 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 and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, 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 for 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 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(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 Partnership Parties, on the one hand, and the Underwriters on the other, from the offering of the Units 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 Parties, on the one hand, and the Underwriters on the other, with respect to the statements or omissions that 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 Partnership 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 Units purchased under this Agreement (before deducting expenses) received by the Partnership, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Units purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. 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 Parties 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 Partnership Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) 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 that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(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 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Units underwritten by it exceeds the amount of any damages that 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 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Partnership Parties acknowledge and agree that the statements regarding delivery of the Units by the Underwriters set forth on the cover page of, and the concession and reallowance figures and the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the most recent Preliminary Prospectus and 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 any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show.

Section 9. Defaulting Underwriters.

If, on any 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 Units that the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of the Firm Units set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of Firm Units set forth 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 Units on such Delivery Date if the total number of the Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of Units to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of Units that it agreed to purchase on such 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, all the Units to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representative do not elect to purchase the Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriters to purchase, and of the Partnership to sell, the Option Units) shall terminate without liability on the part of any non-defaulting Underwriter or the Partnership Parties, except that the Partnership Parties will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. 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 that, pursuant to this Section 9, purchases Units that a defaulting Underwriter agreed but failed to purchase.

Section 10. 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 Firm Units if, prior to that time, any of the events described in Sections 7(k), 7(l), or 7(m) shall have occurred or if the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement.

Section 11. Reimbursement of Underwriters’ Expenses.

(a) If the Partnership shall fail to tender the Units for delivery to the Underwriters by reason of any failure, refusal or inability on the part of any of the Partnership Parties 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 any of the Partnership Parties is not fulfilled for any reason, the Partnership 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 Units, and upon demand the Partnership Parties shall pay the full amount thereof to the Representative. If this Agreement is terminated pursuant to Section 7(m)(i), (iii), (iv) or (v) or Section 9 by reason of the default of one or more Underwriters, the Partnership Parties shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

Section 12. Research Independence.

The Partnership Parties acknowledge 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 such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership Parties and/or the offering that differ from the views of their respective investment banking divisions. The Partnership Parties hereby waive and release, to the fullest extent permitted by law, any claims that the Partnership Parties 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 Parties by such Underwriters’ investment banking divisions. The Partnership Parties acknowledge that each of the Underwriters 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 the companies that may be the subject of the transactions contemplated by this Agreement.

Section 13. No Fiduciary Duty.

The Partnership Parties acknowledge and agree that in connection with this offering, sale of the Units or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any

oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Partnership Entities and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to any of the Partnership Entities, including, without limitation, with respect to the determination of the public offering price of the Units, and such relationship between the Partnership Entities, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Partnership Entities shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Partnership Entities. The Partnership Entities hereby waive any claims that they may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering of the Units.

LOCK-UP LETTER AGREEMENT

LEHMAN BROTHERS INC.

As Representative of the several

Underwriters named in Schedule 1,

c/o Lehman Brothers Inc.

745 Seventh Avenue

New York, New York 10019

Ladies and Gentlemen:

The undersigned understands that you and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Sunoco Partners LLC, Sunoco Logistics Partners L.P., a Delaware limited partnership (the “Partnership”), and the other parties named therein (collectively, the “Partnership Parties”), providing for the purchase by the Underwriters of common units representing limited partner interests (the “Common Units”) of the Partnership, and that the Underwriters propose to reoffer the Common Units to the public (the “Offering”). Capitalized terms used but not defined herein have the meanings given them in the Underwriting Agreement.

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Lehman Brothers Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise transfer or dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Units (including, without limitation, Common Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Common Units that may be issued upon exercise of any options or warrants) or securities convertible into or exchangeable for Common Units owned by the undersigned on the date of the execution of this Agreement or on the date of the completion of the Offering, or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Common Units or securities convertible into or exchangeable for Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right to file or cause to be filed a registration statement, including any amendments thereto, to register any Common Units or securities convertible, exercisable or exchangeable into Common Units or any other securities of the Partnership or (4) publicly disclose the intention to do any of the foregoing, in each case, for a period of seventy-five (75) days from the date of the final prospectus relating to the Offering (such seventy-five day period, the “Lock-Up Period”). The foregoing sentence shall not apply to bona fide gifts, sales or other dispositions of Common Units, in each case that are made exclusively between and among the undersigned or members of the undersigned’s family, or affiliates of the undersigned, including its partners (if a partnership) or members (if a limited

Exhibit A-1

liability company); provided that it shall be a condition to any such transfer that (i) the transferee/donee agrees to be bound by the terms of this Lock-up Letter Agreement (including, without limitation, the restrictions set forth in the preceding sentence) to the same extent as if the transferee/donee were a party hereto, (ii) no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), shall be required or shall be voluntarily made in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the Lock-Up Period), (iii) each party (donor, donee, transferor or transferee) shall not be required by law (including without limitation the disclosure requirements of the Securities Act of 1933, as amended, and the Exchange Act) to make, and shall agree to not voluntarily make, any public announcement of the transfer or disposition, and (iv) the undersigned notifies Lehman Brothers’ Equity Capital Markets at least two business days prior to the proposed transfer or disposition.

In furtherance of the foregoing, the Partnership and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Partnership notifies the Underwriters that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Units, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Partnership and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Partnership Parties and the Underwriters.

[Signature page follows]

Exhibit A-2

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.

The foregoing indemnity agreement is in addition to any liability which the Partnership Parties may otherwise have to any Underwriter or to any officer, director, employee or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Partnership Parties, their respective employees, the officers and directors of the General Partner, and each person, if any, who controls the Partnership Parties within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Partnership Parties or any such officer, director, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Issuers through the Representatives by or on behalf of that

Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e) hereof. The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Partnership Parties or any such officer, director, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 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 8, 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 8 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 8. 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 8 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 Representatives shall have the right to employ counsel to represent jointly the Representatives and those other Underwriters and their respective officers, directors, 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 Partnership Parties under this Section 8 if, (i) the Partnership Parties and the Underwriters shall have so mutually agreed; (ii) the Partnership Parties have failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriters; (iii) the Underwriters and their respective directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the Partnership Parties; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriters or their respective directors, officers, employees or controlling persons, on the one hand, and the Partnership Parties, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Partnership 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 and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, 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 for 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 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(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 Partnership Parties, on the one hand, and the Underwriters on the other, from the offering of the Securities 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 Parties, on the one hand, and the Underwriters on the other, with respect to the statements or omissions that 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 Partnership 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 Securities purchased under this Agreement (before deducting expenses) received by the Operating Partnership, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Securities purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. 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 Parties 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 Partnership Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) 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 that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(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 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Securities underwritten by it exceeds the amount of any damages that 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 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Partnership Parties acknowledge and agree that the statements regarding delivery of the Securities by the Underwriters set forth on the

cover page of, and the concession and reallowance figures and the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Issuers by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show.

Section 9. Defaulting Underwriters.

If, on any 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 Securities that the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the principal amount of the Securities set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total principal amount of Securities set forth 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 Securities on such Delivery Date if the total principal amount of Securities that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the aggregate principal amount of Securities to be purchased on such Delivery Date. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives 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 Securities to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Securities that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Partnership Parties, except that the Partnership Parties will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. 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 that, pursuant to this Section 9, purchases Securities 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 Partnership Parties for damages caused by its default. If other Underwriters are obligated or agree to purchase the Securities of a defaulting or withdrawing Underwriter, either the Representatives or the Issuers 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 Issuers or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus, the Pricing Disclosure Package or in any other document or arrangement.

Section 10. Termination.

The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Issuers prior to delivery of and payment for the Securities if, prior to that time, any of the events described in Sections 7(k), 7(l), or 7(m) shall have occurred or if the Underwriters shall decline to purchase the Securities for any reason permitted under this Agreement.

Section 11. Reimbursement of Underwriters’ Expenses.

(a) If the Issuers shall fail to tender the Securities for delivery to the Underwriters by reason of any failure, refusal or inability on the part of any of the Partnership Parties 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 any of the Partnership Parties is not fulfilled for any reason the Partnership 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 Securities, and upon demand the Partnership Parties shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 7(m)(i), (iii), (iv) or (v) or Section 9 by reason of the default of one or more Underwriters, the Partnership Parties shall not be obligated to reimburse any defaulting Underwriter on account of those expenses.

Section 12. Research Independence.

Section 13. No Fiduciary Duty.

The Partnership Parties acknowledge and agree that in connection with this offering, sale of the Securities or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Partnership Entities and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to any of the Partnership Entities, including, without limitation, with respect to the determination of the public offering price of the Securities, and such relationship between the Partnership Entities, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Partnership Entities shall be limited to

those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Partnership Entities. The Partnership Entities hereby waive any claims that they may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering of the Securities.

Section 14. Notices, Etc.

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

(a) if to the Underwriters, shall be delivered or sent by mail or facsimile transmission to Barclays Capital Inc., 200 Park Avenue, New York, New York 10166, Attention: Fixed Income Syndicate (Fax: 212-412-7305), with a copy, in the case of any notice pursuant to Section 8(c), to the Office of the General Counsel (Fax: 212-412-7519);

provided, however, that any notice to an Underwriter pursuant to Section 8(c) shall be delivered or sent by mail or facsimile transmission to such Underwriter at its address set forth in its acceptance telex to the Representatives, which address will be supplied to any other party hereto by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Partnership 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 Representatives.

Section 15. Persons Entitled to Benefit of Agreement.

Section 16. Survival.

The respective indemnities, representations, warranties and agreements of the Partnership Parties and the Underwriters contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Securities 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 17. Definition of the Terms “Business Day” “Subsidiary” and “Affiliate”.

Section 18. Governing Law.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

Section 19. Counterparts.

WHEREAS, the Partnership has duly authorized and desires to cause to be issued pursuant to the Original Indenture and this First Supplemental Indenture one series of Debt Securities designated the “6.125% Senior Notes due 2016” (the “Notes”), all of such Notes to be guaranteed by the Parent Guarantor and the Subsidiary Guarantors as provided in Article XIV of the Original Indenture;

NOW, THEREFORE, the Issuer, the Parent Guarantor and the Trustee hereby agree that the following provisions shall supplement the Original Indenture:

ARTICLE I.

THE NOTES

SECTION 1.1 Form.

The Notes shall be issued upon original issuance in whole in the form of one or more Global Securities (the “Book-Entry Notes”). Each Book-Entry Note shall represent such of the Outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate amount of Outstanding Notes from time to time endorsed thereon and that the aggregate amount of Outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Book-Entry Note to reflect the amount, or any increase or decrease in the amount, of Outstanding Notes represented thereby shall be made by the Trustee in accordance with written instructions or such other written form of instructions as is customary for the Depositary, from the Depositary or its nominee on behalf of any Person having a beneficial interest in the Book-Entry Note.

Such order shall specify the amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated, and the name or names of the initial Holder or Holders. The aggregate principal amount of Notes that may be outstanding at any time may not exceed $175 million plus such additional principal amounts as may be issued and authenticated pursuant to clause (ii) of this paragraph (except as provided in Section 2.09 of the Indenture).

The principal amount of each Note shall be payable on May 15, 2016. Each Note shall bear interest from the date of original issuance, or the most recent date to which interest has been

paid, at the fixed rate of 6.125% per annum. The dates on which interest on the Notes shall be payable shall be May 15 and November 15 of each year, commencing November 15, 2006 in the case of the Original Notes (the “Interest Payment Dates”). The regular record date for interest payable on the Notes on any Interest Payment Date shall be May 1 or November 1 (the “Regular Record Date”), as the case may be, next preceding such Interest Payment Date.

Payments of principal of, premium, if any, and interest due on the Notes representing Book-Entry Notes on any Interest Payment Date or at maturity will be made available to the Trustee by 11:00 a.m., New York City time, on such date, unless such date falls on a day which is not a Business Day, in which case such payments will be made available to the Trustee by 11:00 a.m., New York City time, on the next Business Day.

There is excluded from this restriction:

(1) Permitted Liens:

(2) any Lien upon any property or asset created at the time of the acquisition of that property or asset by the Partnership or any of its Subsidiaries or within one year after that time to secure all or a portion of the purchase price for that property or asset or Debt incurred to finance the purchase price, whether that Debt was incurred prior to, at the time of or within one year after the date of the acquisition;

(7) Liens imposed by law or order as a result of any proceeding before any court or regulatory or body that is being contested in good faith, and Liens which secure a judgment or other court-ordered award or settlement as to which the Partnership or the applicable Subsidiary have not exhausted its appellate rights;

(8) any extension, renewal, refinancing, refunding or replacement, or successive extensions, renewals, refinancings, refundings or replacements, of Liens, in whole or in part, referred to in clauses (1) through (7) above; provided, however, that any extension, renewal, refinancing, refunding or replacement Lien shall be limited to the property or asset covered by the Lien extended, renewed, refinanced, refunded or replaced and that the obligations secured by any extension, renewal, refinancing, refunding or replacement Lien shall be in an amount not greater than the amount of the obligations secured by the Lien extended, renewed, refinanced, refunded or replaced and any expenses of the Partnership and its Subsidiaries, including any premium, incurred in connection with any extension, renewal, refinancing, refunding or replacement; or

(9) any Lien resulting from the deposit of moneys or evidence of indebtedness in trust for the purpose defeasing Debt of the Partnership or any of its Subsidiaries.

Section 4.13. Restrictions on Sale-Leasebacks.

(iii) The Partnership will not, and will not permit any of its Subsidiaries to, engage in the sale or transfer by the Partnership or any of its Subsidiaries of any Principal Property to a Person, other than the Partnership or any of its Subsidiaries, and the taking back by the Partnership or any Subsidiary, as the case may be, of a lease of the Principal Property (a “Sale-Leaseback Transaction”), unless:

SECTION 1.10 Additional Definitions

In the case of any lease that is terminable by the lessee upon the payment of a penalty or other termination payment, the amount shall be the lesser of the amount determined assuming termination upon the first date the lease may be terminated, in which case the amount shall also include the amount of the penalty or termination payment, but no rent shall be considered as required to be paid under the lease subsequent to the first date upon which it may be so terminated, or the amount determined assuming no termination.

“Consolidated Net Tangible Assets” means, at any date of determination, the total amount of assets after deducting:

[REVERSE OF SECURITY]

SUNOCO LOGISTICS PARTNERS OPERATIONS L.P.

6.125% SENIOR NOTE DUE 2016

This Security is one of a duly authorized issue of debentures, notes or other evidences of indebtedness of the Partnership (the “Debt Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Partnership, the Parent Guarantor, the Subsidiary Guarantors and the Holders of the Debt Securities. The Debt Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as provided in the Indenture. This Security is one of a series designated as the 6.125% Senior Notes due 2016 of the Partnership, in initial aggregate principal amount of $175 million (the “Securities”).

1. Interest.

The Partnership promises to pay interest on the principal amount of this Security at the rate of 6.125% per annum.

The Partnership will pay interest semi-annually on May 15 and November 15 of each year (each an “Interest Payment Date”), commencing November 15, 2006. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid on the Securities, from May 8, 2006. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Partnership shall pay interest (including post-petition interest in any proceeding under any applicable bankruptcy laws) on overdue installments of interest (without regard to any applicable grace period) and on overdue principal and premium, if any, from time to time on demand at the same rate per annum, in each case to the extent lawful.

2. Method of Payment.

The Partnership shall pay interest on the Securities (except Defaulted Interest) to the persons who are the registered Holders at the close of business on the Regular Record Date immediately preceding the Interest Payment Date. Any such interest not so punctually paid or duly provided for (“Defaulted Interest”) may be paid to the persons who are registered Holders at the close of business on a special record date for the payment of such Defaulted Interest, or in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may then be listed if such manner of payment shall be deemed practicable by the Trustee, as more fully provided in the Indenture. The Partnership shall pay principal, premium, if any, and interest in such coin or currency of the United States of America as at the time of payment shall be legal tender for payment of public and private debts. Payments in respect of a Global Security (including principal, premium, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by the Depositary. Payments in respect of Securities in definitive form (including principal, premium, if any, and

A-4

interest) will be made at the office or agency of the Partnership maintained for such purpose within The City of New York, which initially will be Citibank, N.A., 111 Wall Street, 15^th Floor, New York, New York 10005 Attention: Window, or, at the option of the Company, payment of interest may be made by check mailed to the Holders on the relevant record date at their addresses set forth in the Debt Security register of Holders or at the option of the Holder, payment of interest on Securities in definitive form will be made by wire transfer of immediately available funds to any account maintained in the United States, provided such Holder has requested such method of payment and provided timely wire transfer instructions to the paying agent. The Holder must surrender this Security to a paying agent to collect payment of principal.

3. Paying Agent and Registrar.

Initially, Citibank, N.A. will act as paying agent and Registrar. The Partnership may change any paying agent or Registrar at any time upon notice to the Trustee and the Holders. The Partnership may act as paying agent.

4. Indenture.

This Security is one of a duly authorized issue of Debt Securities of the Partnership issued and to be issued in one or more series under the Indenture.

Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Original Indenture, those made part of the Indenture by reference to the TIA, as in effect on the date of the Original Indenture, and those terms stated in the First Supplemental Indenture. The Securities are subject to all such terms, and Holders of Securities are referred to the Original Indenture, the First Supplemental Indenture and the TIA for a statement of them. The Securities of this series are general unsecured obligations of the Company limited to an initial aggregate principal amount of $175 million; provided, however, that the authorized aggregate principal amount of such series may be increased from time to time as provided in the First Supplemental Indenture.

5. Optional Redemption.

The Securities are redeemable, at the option of the Partnership, at any time in whole, or from time to time in part, at a redemption price (the “Make-Whole Price”) equal to the greater of: (i) 100% of the principal amount of the Securities to be redeemed; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest (at the rate in effect on the date of calculation of the redemption price) on the Securities (exclusive of interest accrued to the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 15 basis points; plus, in either case, accrued and unpaid interest to the Redemption Date.

The actual Make-Whole Price, calculated as provided above, shall be calculated and certified to the Trustee and the Partnership by the Independent Investment Banker. For purposes of determining the Make-Whole Price, the following definitions are applicable:

“Treasury Rate” means the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury

A-5

Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third business day preceding the Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities.

“Comparable Treasury Price” means with respect to any Redemption Date (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means either Barclays Capital Inc. or Citigroup Global Markets Inc., as specified by the Partnership, and any successor firm or, if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Partnership.

“Reference Treasury Dealer” means each of Barclays Capital Inc. and Citigroup Global Markets Inc. and three other primary U.S. government securities dealers (each a “Primary Treasury Dealer”), as specified by the Partnership; provided, that (1) if any of Barclays Capital Inc., Citigroup Global Markets Inc. or any Primary Treasury Dealer as specified by the Partnership shall cease to be a Primary Treasury Dealer, the Partnership will substitute therefor another Primary Treasury Dealer and (2) if the Partnership fails to select a substitute within a reasonable period of time, then the substitute will be a Primary Treasury Dealer selected by the Independent Investment Banker.

“Reference Treasury Dealer Quotations” means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding such Redemption Date.

Except as set forth above, the Securities will not be redeemable prior to their Stated Maturity and will not be entitled to the benefit of any sinking fund.

Securities called for optional redemption become due on the Redemption Date. Notices of optional redemption will be mailed at least 30 but not more than 60 days before the Redemption Date to each Holder of the Securities to be redeemed at its registered address. The notice of optional redemption for the Securities will state, among other things, the amount of Securities to be redeemed, the Redemption Date, the method of calculating such redemption price and the place(s) that payment will be made upon presentation and surrender of Securities to be redeemed. Unless the Partnership defaults in payment of the redemption price, interest will

A-6

cease to accrue on the Redemption Date with respect to any Securities that have been called for optional redemption. If less than all the Securities are redeemed at any time, the Trustee will select the Securities to be redeemed on a pro rata basis, by lot or by any other method the Trustee deems fair and appropriate; provided, however, that if at the time of redemption such Securities are represented by a Global Security, the Depositary shall determine, in accordance with its procedures, the principal amount of such Securities held by each beneficial owner to be redeemed.

The Securities may be redeemed in part in multiplies of $1,000 only. Any such redemption will also comply with Article III of the Indenture.

6. Denominations; Transfer; Exchange.

The Securities are to be issued in registered form, without coupons, in denominations of $1,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange, Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

7. Person Deemed Owners.

The registered Holder of a Security may be treated as the owner of it for all purposes.

8. Amendment; Supplement; Waiver.

Subject to certain exceptions, the Indenture may be amended or supplemented, and any existing Event of Default or compliance with any provision may be waived, with the consent of the Holders of a majority in principal amount of the Outstanding Debt Securities of each series affected. Without consent of any Holder of a Security, the parties thereto may amend or supplement the Indenture to, among other things, cure any ambiguity or omission, to correct any defect or inconsistency, or to make any other change that does not adversely affect the rights of any Holder of a Security. Any such consent or waiver by the Holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such Holder and upon all future Holders and owners of this Security and any Securities which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Security or such other Securities.

9. Defaults and Remedies.

Certain events of bankruptcy or insolvency are Events of Default that will result in the principal amount of the Securities, together with premium, if any, and accrued and unpaid interest thereon, becoming due and payable immediately upon the occurrence of such Events of Default. If any other Event of Default with respect to the Securities occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the Securities then Outstanding may declare the principal amount of all the Securities, together with premium, if any, and accrued and unpaid interest thereon, to be due and payable immediately in the manner and with the effect provided in the Indenture. Notwithstanding the preceding sentence, however, if at any time after such a declaration of acceleration has been

A-7

made, the Holders of a majority in principal amount of the Outstanding Securities, by written notice to the Trustee, may rescind such declaration and annul its consequences if the rescission would not conflict with any judgment or decree of a court already rendered and if all Events of Default with respect to the Securities, other than the nonpayment of the principal, premium, if any, or interest which has become due solely by such acceleration, shall have been cured or shall have been waived. No such rescission shall affect any subsequent default or shall impair any right consequent thereon. Holders of Securities may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the Trustee in its exercise of any trust or power.

10. Trustee Dealings with Partnership.

The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Partnership or its Affiliates or any subsidiary of the Partnership’s Affiliates, and may otherwise deal with the Company or its Affiliates as if it were not the Trustee.

11. Authentication.

This Security shall not be valid until the Trustee signs the certificate of authentication on the other side of this Security.

12. Abbreviations and Defined Terms.

Customary abbreviations may be used in the name of a Holder of a Security or an assignee, such as: TEN COM (tenant in common), TEN ENT (tenants by the entireties), JT TEN (joint tenants with right of survivorship and not as tenants in common), CUST (Custodian), and U/G/M/A (Uniform Gifts to Minors Act).

13. CUSIP Numbers.

Pursuant to a recommendation promulgated by the Committee on Uniform Note Identification Procedures, the Partnership has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such number as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

14. Absolute Obligation.

No reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation of the Partnership, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Security in the manner, at the respective times, at the rate and in the coin or currency herein prescribed.

Each Holder by accepting the Securities waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.

16. Governing Law.

This Security shall be construed in accordance with and governed by the laws of the State of New York.

The Securities are fully and unconditionally guaranteed on an unsecured, unsubordinated basis by the Parent Guarantor and each of the Subsidiary Guarantors as set forth in Article XIV of the Indenture, as noted in the Notation of Guarantee to this Security, and under certain circumstances set forth in the First Supplemental Indenture one or more Subsidiaries of the Partnership may be required to join in such guarantee.

Philadelphia, Pennsylvania 19103

Ladies and Gentlemen:

We have acted as counsel to Sunoco Logistics Partners L.P., a Delaware limited partnership (the “Partnership”), in connection with the offering by the Partnership of up to 2,760,000 common units (including an option to purchase up to 360,000 units) representing limited partner interests in the Partnership (the “Units”). We refer to the registration statement on Form S-3 (Registration No. 333-130564) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) by the Partnership on December 21, 2005, as amended. A prospectus supplement dated May 2, 2006, which together with the base prospectus filed with the Registration Statement shall constitute part of the prospectus (the “Prospectus”), has been filed pursuant to Rule 424(b) promulgated under the Securities Act.

As the basis for the opinion hereinafter expressed, we examined such statutes, including the Delaware Revised Uniform Limited Partnership Act, corporate records and documents, certificates of public officials, and other instruments and documents as we deemed necessary or advisable for the purposes of this opinion. In such examinations, we assumed the authenticity of all documents submitted to us as originals and the conformity with the original documents of all documents submitted to us as copies. As to various questions of fact material to this opinion, we have relied upon statements and certificates of officers of Sunoco Partners LLC, a Pennsylvania limited liability company and general partner of the Partnership. Without limiting the foregoing, we have examined the Underwriting Agreement, dated May 2, 2006, by and among the Partnership, Sunoco Partners LLC, Sunoco Logistics Partners Operations L.P. and Lehman Brothers Inc., as representative of the several underwriters named therein (the “Underwriting Agreement”).

In connection with this opinion, we have assumed that all Units will be issued and sold in the manner stated in the Prospectus and the Underwriting Agreement.

Based on the foregoing, we are of the opinion that the Units, when issued and delivered to and paid for by the Underwriters in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and nonassessable except as described in the Prospectus.

The opinions expressed herein are limited exclusively to the federal laws of the United States of America and the Revised Uniform Limited Partnership Act of the State of Delaware and the Constitution of the State of Delaware, each as interpreted by the courts of the State of Delaware, and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

We hereby consent to the references to this firm under the caption “Legal” in the Prospectus and to the filing of this opinion as an exhibit to a Current Report on Form 8-K. By giving such consent, we do not admit that we are within the category of persons whose consent is required under the provisions of the Securities Act or the rules and regulations of the Commission issued thereunder.

In addition, we reviewed such questions of law as we considered appropriate.

As to any facts material to the opinions contained herein, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Operating Partnership.

In connection with rendering the opinions set forth below, we have assumed that (i) all information contained in all documents reviewed by us is true and correct; (ii) all signatures on all documents examined by us are genuine; (iii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the originals of those documents; (iv) each natural person signing any document reviewed by us had the legal capacity to do so; (v) each person signing in a representative capacity (other than on behalf of the Operating Partnership, the Partnership, Sunoco M&T LP and Sunoco Pipeline LP) any document reviewed by us had authority to sign in such capacity; (vi) all Securities will be issued and sold in compliance with applicable federal and state securities laws and in the manner stated in the Prospectus and the Registration Statement; and (vii) the Senior Indenture and the Supplemental Indenture each were duly authorized, executed and delivered by the parties thereto in substantially the form reviewed by us or with changes that do not affect the opinions given hereunder.

Based on the foregoing, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that the Securities have been duly

authorized, executed and issued by the Operating Partnership, the Partnership, Sunoco M&T LP and Sunoco Pipeline LP and, assuming that the Securities have been duly authenticated by Citibank, N.A., as Trustee, constitute valid and binding obligations of the Operating Partnership, the Partnership, Sunoco M&T LP and Sunoco Pipeline LP, enforceable against the Operating Partnership, the Partnership, Sunoco M&T LP and Sunoco Pipeline LP in accordance with their terms and will be entitled to the benefits of the Senior Indenture, as amended and supplemented by the Supplemental Indenture.

The foregoing opinion is qualified to the extent that the enforceability of any document, instrument or security may be limited by or subject to bankruptcy, insolvency, fraudulent transfer or conveyance, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally, and general equitable or public policy principles.

We express no opinions concerning (i) the validity or enforceability of any provisions contained in the Senior Indenture or the Supplemental Indenture that purport to waive or not give effect to rights to notices, defenses, subrogation or other rights or benefits that cannot be effectively waived under applicable law or (ii) the enforceability of indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws.

Ladies and Gentlemen:

We have acted as counsel for Sunoco Logistics Partners L.P. (the “Partnership”), a Delaware limited partnership, with respect to certain legal matters in connection with the offer and sale of common units representing limited partner interests in the Partnership.
