Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the requirements of the Securities Act and the rules and regulations of the Commission under the Securities Act (the “Securities Act Regulations”). Each preliminary prospectus, the Prospectus and any amendment or supplement thereto, at the time each was filed with the Commission, complied in all material respects with the requirements of the Securities Act and the Securities Act Regulations. Each document, if any, filed pursuant to the Exchange Act and incorporated by reference in the Time of Sale Prospectus or the Prospectus complied when so filed in all material respects with the Exchange Act and the applicable rules and regulations of the Commission thereunder. Each preliminary prospectus delivered to the Underwriters for use in connection with this offering and the Prospectus was or will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to Electronic Data Gathering, Analysis and Retrieval system or any successor system, except to the extent permitted by Regulation S-T.

(b) Accurate Disclosure. Neither the Registration Statement nor any post-effective amendment thereto, at its effective time contained an 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. As of the Applicable Time, the Closing Date and each Option Closing Date, if any, (i) the Time of Sale Prospectus and (ii) any individual free writing prospectus, when taken together as a whole with the Time of Sale Prospectus, did not and will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Neither the Prospectus nor any supplement thereto, as of its issue date, at the time of any filing with the Commission pursuant to Rule 424(b), at the Applicable Time or at the Closing Date, will include an untrue statement of a material fact or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(e) If the Time of Sale Prospectus is being used to solicit offers to buy the Units at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(f) If, during such period after the first date of the public offering of the Units as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law,

forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the Partnership) to which Units may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

(g) To endeavor to qualify the Units for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request.

(h) To make generally available to the Partnership’s security holders and to you as soon as practicable an earnings statement of the Partnership (which need not be audited) which shall satisfy the provisions of Section 11(a) of the Securities Act and the Securities Act Regulations (including, at the option of the Partnership, Rule 158).

(i) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Partnership’s counsel and the Partnership’s accountants in connection with the registration and delivery of the Units under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Partnership and amendments and supplements to any of the foregoing, including the filing fees payable to the Commission relating to the Units (within the time required by Rule 456(b)(1), if applicable), all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Units to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Units under state securities laws and all expenses in connection with the qualification of the Units for offer and sale under state securities laws as provided in Section 6(g) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Units by FINRA, (v) all costs and expenses incident to listing the Units on the New York Stock Exchange, (vi) the cost of printing certificates representing the Units, (vii) the costs and charges of any transfer agent, registrar or depositary, (viii) the costs and expenses of the Partnership relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Units, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with

the prior approval of the Partnership, travel and lodging expenses of the representatives and officers of the Partnership, and 50.0% of the cost of any aircraft chartered in connection with the road show, (ix) the document production charges and expenses associated with printing this Agreement and (x) all other costs and expenses incident to the performance of the obligations of the Partnership hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section 6, Section 8 entitled “Indemnification” and Section 9 entitled “Contribution” and the last paragraph of Section 11 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, transfer taxes payable on resale of any of the Units by them and any advertising expenses connected with any offers they may make.

(j) If the third anniversary of the initial effective date of the Registration Statement occurs before all the Units have been sold by the Underwriters, prior to the third anniversary to file a new shelf registration statement and to take any other action necessary to permit the public offering of the Units to continue without interruption; references herein to the Registration Statement shall include the new registration statement declared effective by the Commission;

(k) If requested by the Manager, to prepare a final term sheet relating to the offering of the Units, containing only information that describes the final terms of the offering in a form consented to by the Manager, and to file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the offering of the Units.

The Partnership also covenants with each Underwriter that, without the prior written consent of the Manager, it will not, during the restricted period set forth in Schedule I hereto (the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Units or any securities convertible into or exercisable or exchangeable for Common Units or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or such other securities, in cash or otherwise or (3) file any registration statement with the Commission relating to the offering of any Common Units or any securities convertible into or exercisable or exchangeable for Common Units (except for the filing of a registration statement on Form S-8 to register Common Units under existing employee benefit or equity compensation plans or a registration statement on Form S-3 to register Common Units or other Partnership securities, provided that the Partnership shall not issue any Common Units thereunder until expiration of the Restricted Period). The foregoing sentence shall not apply to (a) the Units to be sold hereunder, (b) the issuance by the Partnership of Common Units upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof of which the Underwriters have been advised in writing, (c) the issuance of Common Units or options to purchase Common Units granted pursuant to an existing employee benefit or equity compensation plans, (d) the deemed issuance of Common Units under Section 16 of the Exchange Act upon the cash settlement of phantom units or unit appreciation rights outstanding as of the date of this Agreement, (e) the

issuance of any equity interest in connection with the transactions contemplated by the Contribution Agreement or (f) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Common Units, provided that (i) such plan does not provide for the transfer of Common Units during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by the Partnership regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Units may be made under such plan during the Restricted Period.

7. Covenants of the Underwriters. Each Underwriter severally covenants with the Partnership not to take any action that would result in the Partnership being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Partnership thereunder, but for the action of the Underwriter.

8. Indemnification.

(a) The Partnership agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) under the Securities Act (each, an “Affiliate”)), directors, officers, employees, selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included (A) in any preliminary prospectus, any free writing prospectus, the Time of Sale Prospectus or the Prospectus (or any amendment or supplement of the foregoing), or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or (B) in any materials or information provided to investors by, or with the approval of, the Partnership in connection with the marketing of the offering of the Units (“Marketing Materials”), including any road show or investor presentations made to investors by the Partnership (whether in person or electronically), or the omission or alleged omission in any preliminary prospectus, free writing prospectus, Prospectus or in any Marketing Materials of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 8(d) below) any such settlement is effected with the written consent of the Partnership;

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

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including the Time of Sale Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(b) Indemnification of the Partnership. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Partnership, each director and officer of the General Partner who signed the Registration Statement, and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in Section 8(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Time of Sale Prospectus or the Prospectus (or any supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 8(a) above, counsel to the indemnified parties shall be selected by the Manager, and, in the case of parties indemnified pursuant to Section 8(b) above, counsel to the indemnified parties shall be selected by the Partnership. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

(d) Settlement Without Consent if Failure to Reimburse. The indemnifying party under this Section 8 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 against any loss, claim, damage, liability or expense by reason of such settlement or judgment; provided, however, that if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 60 days prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity or contribution was or could have been sought under this Section 8 or Section 9 hereof by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to, any findings or admission of fault, culpability or failure to act by or on behalf of any indemnified party.

9. Contribution.

(a) If the indemnification provided for in Section 8 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (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 Units pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) 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, liabilities, claims, damages or expenses, 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 Units pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Units pursuant to this Agreement (before deducting expenses) received by the Partnership, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Units as set forth on the cover of the Prospectus. 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 any such 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 by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(b) The Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 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 which does not take account of the equitable considerations referred to in Section 9(a) hereof. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to in Section 9(a) hereof shall be deemed to include any legal counsel expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Common Units underwritten by it and distributed to the public. 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.

(c) For purposes of this Section 9, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each Underwriter’s Affiliates, directors, officers, employees and selling agents shall have the same rights to contribution as such Underwriter, and each director and officer of the General Partner who signed the Registration Statement, and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Partnership. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to the number of Units set forth opposite their respective names in Schedule II hereto.

10. Termination. The Underwriters may terminate this Agreement by notice given by you 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 Stock 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 Units on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

11. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Units that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Units, 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 Units to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Units set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Units set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Common Units 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 Common Units that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such number of Common Units without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Units and the aggregate number of Firm Units with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Units to be purchased on such date, and arrangements satisfactory to you and the Partnership for the purchase of such Firm Units 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. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Units and the aggregate number of Additional Units with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Units to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Units to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Units that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. 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 this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Partnership to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Partnership shall be unable to perform its obligations under this Agreement, the Partnership will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

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 Common Units, 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 Common Units.

(b) The Partnership acknowledges that in connection with the offering of the Common Units: (i) the Underwriters have acted at arm’s 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 Common Units.

13. 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.

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

15. 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.

16. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to you at the address set forth in Schedule I hereto; and if to the Partnership shall be delivered, mailed or sent to the address set forth in Schedule I hereto.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Partnership a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriters and the Partnership in accordance with its terms.

FORM OF OPINION OF PARTNERSHIP’S COUNSEL

TO BE DELIVERED PURSUANT TO SECTION 5(c)

We have acted as special counsel to Sunoco LP, a Delaware limited partnership (the “Issuer”), in connection with the Underwriting Agreement dated [Pricing Date] (the “Underwriting Agreement”) by and among (i) the Issuer and (ii) Xxxxxx Xxxxxxx & Co. LLC, as representative of the several underwriters named therein (the “Underwriters”), relating to the sale by the Issuer to the Underwriters of [ ] common units (the “Firm Securities”) representing limited partner interests in the Issuer (“Common Units”). Pursuant to the Underwriting Agreement, the Issuer has granted an option to the Underwriters to purchase up to an additional [ ] Common Units (the “Option Securities”). The Firm Securities and the Option Securities are collectively referred to herein as the “Securities.”

In rendering the opinions set forth herein, we have examined and relied on originals or copies, certified or otherwise identified to our satisfaction, of the following:

In addition, we have participated in conferences with officers and other representatives of the General Partner and the Issuer, the independent registered public accounting firm for the Issuer, your counsel and your representatives at which the contents of the Registration Statement, the Disclosure Package and the Prospectus and related matters were discussed and, although we have not independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus (except as and to the extent set forth in paragraphs 16 and 17 above), on the basis of the foregoing (relying with respect to factual matters to the extent we deem appropriate upon statements by officers and other representatives of the General Partner), (a) we confirm to you that, in our opinion, each of the Registration Statement, as of its most recent effective date, the Preliminary Prospectus, as of its date, and the Prospectus, as of its date, appeared on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the Rules and Regulations (except that we express no statement or belief as to Regulation S-T), (b) we have not become aware of any documents that are required to be filed as exhibits to the Registration Statement and are not so filed or of any documents that are required to be summarized in the Preliminary Prospectus or the Prospectus, and are not so summarized and (c) furthermore, no facts have come to our attention that have led us to believe that (i) the Registration Statement, at the time it became effective and as of its most recent effective date, insofar as relating to the offering of the Firm Securities, contained an untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Disclosure Package, as of [ : ] [a.m./p.m] on July [ ], 2015 (which you have informed us is a time prior to the time of the first sale of the Firm Securities by any Underwriter), insofar as relating to the offering of the Firm Securities, contained an untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (iii) the Prospectus, as of its date and as of the date hereof, insofar as relating to the offering of the Firm Securities, contained or contains an untrue statement of a material fact or omitted or omits to state any

Exhibit A-1-8

material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, it being understood that we express no opinion, statement or belief in this letter with respect to (A) the historical and pro forma financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon, (B) any other financial or accounting data, included or incorporated or deemed incorporated by reference in, or excluded from, the Registration Statement, the Prospectus or the Disclosure Package and (C) representations and warranties and other statements of fact included in the exhibits to the Registration Statement or Incorporated Documents.

Furthermore, we advise you that the Registration Statement became effective upon filing under Rule 462(e) under Securities Act. In addition, based solely on our review of the information made available by the SEC at xxxx://xxx.xxx.xxx/xxxxxxxxxx/xxxxxxxxxx.xxxxx, we confirm that the SEC has not issued any stop order suspending the effectiveness of the Registration Statement. To our knowledge, based solely on our participation in the conferences mentioned above regarding the Registration Statement, no proceedings for that purpose are pending or have been instituted or threatened by the SEC.

We express no opinion as to the laws of any jurisdiction other than (i) applicable laws of the State of New York, (ii) applicable laws of the State of Texas, (iii) applicable laws of the United States of America, (iv) certain other specified laws of the United States of America to the extent referred to specifically herein, (v) the Delaware LP Act and (vi) the Delaware LLC Act. References herein to “applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Underwriting Agreement, without our having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references (including without limitation those appearing in paragraphs 14 and 15 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust, laws, rules or regulations.

Our opinions expressed herein are subject to the following additional assumptions and qualifications:

(i) The opinions set forth in paragraph 1 above as to the valid existence and good standing of the Issuer and the other entities mentioned in such paragraph are based solely upon our review of certificates and other communications from the appropriate public officials.

(ii) In rendering the opinion set forth in paragraph 7 above, we have assumed that the consideration recited in the resolutions of the board of directors, members, manager, general partner or other governing body serving similar functions of such subsidiary referred to in such paragraph approving the issuance of all the outstanding equity interests of such subsidiary and (b) the organizational agreement of such subsidiary, as applicable, has been received in full by such subsidiary.

(iii) In making our examination of executed documents, we have assumed (except to the extent that we expressly opine above) (1) the valid existence and good standing of each of the parties thereto, (2) that such parties had the power and authority, corporate, partnership, limited

Exhibit A-1-9

liability company or other, to enter into and to incur and perform all their obligations thereunder, (3) the due authorization by all requisite action, corporate, partnership, limited liability company or other, and the due execution and delivery by such parties of such documents and (4) to the extent such documents purport to constitute agreements, that each of such documents constitutes the legal, valid and binding obligation of each party thereto, enforceable against such party in accordance with its terms. In this paragraph (iii), all references to parties to documents shall be deemed to mean and include each of such parties, and each other person (if any) directly or indirectly acting on its behalf.

(iv) With respect to the opinions expressed in the second sentences of each of paragraphs 4, 5, 6 and 7 above, we have relied solely on the Lien Search Results, and we have assumed the completeness and accuracy of the Lien Search Results and that the methodology utilized in generating the Lien Search Results was effective to disclose all effective uniform commercial code financing statements naming any of ETP, ETC M-A, ETP Retail, the General Partner, the Issuer, Stripes No. 1009 or Stripes as debtor. Furthermore, we have assumed that any uniform commercial code financing statement filed in the office of the Secretary of State of the State of Delaware naming any of ETP, ETC M-A, ETP Retail, the General Partner or the Issuer as debtor or any uniform commercial code financing statement filed in the office of the Secretary of State of the State of Texas naming Stripes No. 1009 or Stripes as debtor would have been properly filed and indexed in the records of the Secretaries of State of the States of Delaware and Texas, respectively. We wish to point out that the DE Search Results purport to disclose all effective uniform commercial code financing statements only through [●], 2015 and the TX Search Results purport to disclose all effective uniform commercial code financing statements only through [●], 2015, and our opinions referred to in the first sentence of this paragraph (iv) are as of that date only.

(v) The opinion set forth in paragraph 17 above with respect to United States federal income tax consequences is based upon our interpretations of current United States federal income tax law, including court authority and existing final and temporary U.S. Treasury regulations, which are subject to change both prospectively and retroactively, and upon the assumptions and qualifications discussed herein. We note that such opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusion. Such opinion is not binding upon the Internal Revenue Service or courts, and there is no guarantee that the Internal Revenue Service will not successfully challenge our conclusions. No assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, would not adversely affect the accuracy of our conclusions.

This opinion is being furnished only to you in connection with the sale of the Firm Securities under the Underwriting Agreement occurring today and is solely for your benefit and is not to be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by any other Person, including any purchaser of any Security from you and any subsequent purchaser of any Security, without our express written permission. The opinions expressed herein are as of the date hereof only and are based on laws, orders, contract terms and provisions, and facts as of such date, and we disclaim any obligation to update this opinion letter after such date or to advise you of changes of facts stated or assumed herein or any subsequent changes in law.

We have acted as special Delaware counsel for Sunoco GP LLC, a Delaware limited liability company (the “General Partner”), in connection with the matters set forth herein. At your request, this opinion is being furnished to you.

For purposes of giving the opinions hereinafter set forth, our examination of documents has been limited to the examination of executed or conformed counterparts, or copies otherwise proved to our satisfaction, of the following:

(a) The First Amended and Restated Agreement of Limited Partnership of Sunoco LP, a Delaware limited partnership (the “Partnership”), dated as of September 25, 2012, among the General Partner, as the general partner of the Partnership, Susser Holdings Corporation, a Delaware corporation, in its capacity as the Organizational Limited Partner (as defined therein), and the other Persons (as defined therein) who become Partners (as defined therein) in the Partnership or parties thereto as provided therein, as amended by the Purchase and Sale Agreement, dated as of September 19, 2014 (the “Purchase Agreement”), between Susser Holdings Corporation and Energy Transfer Partners, L.P.

Initially capitalized terms used herein and not otherwise defined are used as defined in the Partnership Agreement.

For purposes of this opinion, we have not reviewed any documents other than the documents listed in paragraphs (a) and (b) above. In particular, we have not reviewed any document (other than the documents listed in paragraphs (a) and (b) above) that is referred to in or incorporated by reference into any document reviewed by us. We have assumed that there exists no provision in any document that we have not reviewed that is inconsistent with the opinions stated herein. We have conducted no independent factual investigation of our own but rather have relied solely upon the foregoing documents, the statements and information set forth therein and the additional matters recited or assumed herein, all of which we have assumed to be true, complete and accurate in all material respects.

With respect to all documents examined by us, we have assumed that (i) all signatures on documents examined by us are genuine, (ii) all documents submitted to us as originals are authentic, and (iii) all documents submitted to us as copies conform with the originals of those documents.

Exhibit A-3-1

For purposes of this opinion, we have assumed (i) that the Partnership Agreement constitutes the entire agreement among the parties thereto with respect to the subject matter thereof, including with respect to the admission of partners to, and the formation, operation, management and termination of, the Partnership, and that the Partnership Agreement is in full force and effect, has not been amended and no amendment of such document is pending or has been proposed, (ii) that the General Partner Agreement constitutes the entire agreement among the parties thereto with respect to the subject matter thereof, including with respect to the admission of members to, and the formation, operation, management and termination of, the General Partner, and that the General Partner Agreement is in full force and effect, has not been amended and no amendment of such document is pending or has been proposed, (iii) that any amendment or restatement of any document reviewed by us has been accomplished in accordance with, and was permitted by, the relevant provisions of such document prior to its amendment or restatement from time to time, (iv) that there are no proceedings pending or contemplated for the merger, consolidation, conversion, dissolution, liquidation or termination of the Partnership or the General Partner, (v) that each of the General Partner and the Partnership has been duly formed and is validly existing in good standing as a limited liability company or limited partnership, respectively, under the laws of the State of Delaware, (vi) that each party to the documents examined by us has been duly created, organized or formed, as the case may be, and is validly existing in good standing under the laws of the jurisdiction governing its creation, organization or formation, (vii) the legal capacity of natural persons who are signatories to the documents examined by us, (viii) that each of the parties to the documents examined by us has the power and authority to execute and deliver, and to perform its obligations under, such documents, (ix) that each of the parties to the documents examined by us has duly authorized, executed and delivered such documents, including the execution of a counterpart of the General Partner Agreement by ETP, (x) that the transactions contemplated by the Purchase Agreement were accomplished in accordance with the terms of the General Partner Agreement and the Partnership Agreement, (xi) that ETP has been admitted to the General Partner as a member of the General Partner and the General Partner has at all times had at least one member, and (xii) except to the extent provided in paragraphs 1 and 2 below, that each of the documents reviewed by us constitutes a valid and binding agreement of the parties thereto, and is enforceable against the parties thereto, in accordance with its terms. We have not participated in the preparation of any offering material relating to the Partnership or the General Partner and assume no responsibility for the contents of any such material.

This opinion is limited to the laws of the State of Delaware (excluding the securities laws, blue sky laws and tax laws of the State of Delaware), and we have not considered and express no opinion on the laws of any other jurisdiction, including federal laws and rules and regulations relating thereto. Our opinions are rendered only with respect to Delaware laws and rules, regulations and orders thereunder that are currently in effect. In rendering the opinions set forth herein, we express no opinion concerning (i) the creation, attachment, perfection or priority of any security interest, lien or other encumbrance, or (ii) the nature or validity of title to any property.

Based upon the foregoing, and upon our examination of such questions of law and statutes of the State of Delaware as we have considered necessary or appropriate, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that:

1. The Partnership Agreement constitutes a valid and binding agreement of the General Partner, and is enforceable against the General Partner, in accordance with its terms.

We note that various issues relating to the Underwriting Agreement are addressed in the opinions of Xxxxxxx Xxxxx LLP, Williams, Mullen, Xxxxx & Xxxxxxx, P.C., and Xxxxxxxx, Xxxxxx & Finger, PA, which have been separately provided to you. We express no opinion with respect to those matters herein.

In connection with this opinion letter, we have examined and relied on originals or copies, certified or otherwise identified to our satisfaction, of the following:

(i) the Underwriting Agreement;

(ii) the registration statement on Form S-3 (File No. 333-203965) relating to securities to be issued by the Issuer from time to time, including the Securities, filed by the Issuer, under the Securities Act of 1933, as amended (the “Securities Act”), with the U.S. Securities and Exchange Commission (the “SEC”) on May 7, 2015, and including the base prospectus included in such registration statement (the “Base Prospectus”) and the other information set forth in the Incorporated Documents (as defined below) and incorporated by reference in such registration statement and therefore deemed to be a part thereof (such registration statement, as so amended at the time it became effective and including the Base Prospectus and such other information incorporated by reference in such registration statement, being referred to herein as the “Registration Statement”);

(iii) the preliminary prospectus supplement dated July [●], 2015, relating to the Securities, in the form filed with the SEC pursuant to Rule 424(b) of the General Rules and Regulations (the “Rules and Regulations”) under the Securities Act (such preliminary prospectus supplement, together with the Base Prospectus, being referred to herein as the “Preliminary Prospectus”);

Exhibit A-4-1

(v) each of the Issuer’s reports that have been filed with the SEC and are incorporated by reference in the Registration Statement (the “Incorporated Documents”);

(vi) the entire corporate file excluding corporate reports of Aloha certified by the Director of Commerce and Consumer Affairs of the State of Hawaii (the “Director”) and dated [●], 2015;

(vii) the Bylaws of Aloha dated January 27, 1977;

(viii) a Certificate of Good Standing of Aloha, issued by the Director and dated [●], 2015; and

(ix) one or more certificates of officers or other representatives of Aloha.

We have not independently verified any factual matters certified to us. We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of Aloha and such agreements, certificates of public officials, certificates of officers or other representatives of Aloha and others, and such other documents, certificates and records, as we have deemed necessary or appropriate as a basis for the opinions set forth herein. In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as certified or photostatic copies.

Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that:

1. Aloha is a validly existing corporation under the laws of the State of Hawaii.

2. Aloha has the corporate power and authority under its Articles of Incorporation and Bylaws, and under applicable corporate law, to own, lease, and operate its properties and to conduct its business as described in the Registration Statement and the Prospectus.

The opinions expressed herein are limited solely to the laws of the State of Hawaii.

The opinions set forth herein may be relied upon by you only in connection with the transaction described in the Registration Statement and the Prospectus and for no other purpose, and may not be distributed to or relied upon by any other person, quoted in whole or in part, or otherwise reproduced in any other document (except copies of this opinion may be included as an exhibit to the Underwriting Agreement filed with the SEC or in any binder of documents for the transaction to which this opinion relates), nor is it to be filed with any governmental agencies other than the regulatory authorities having jurisdiction over the Issuer or your underwriting business without, in each instance, our prior written consent.
