No fees or commissions are or will be payable by the Purchaser to brokers, finders, or investment bankers with respect to the purchase of the Purchased Units or the consummation of the transactions contemplated by the Basic Documents. The Purchaser agrees that it will indemnify and hold harmless SUN from and against any and all claims, demands or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by the Purchaser or alleged to have been incurred by the Purchaser in connection with the purchase of the Purchased Units or the consummation of the transactions contemplated by the Basic Documents.

Section 4.05     Investment. The Purchased Units are being acquired for the Purchaser’s own account, not as a nominee or agent, and with no present intention of distributing the

12

Purchased Units. The Purchaser understands and acknowledges that there is no public trading market for the Purchased Units and that none is expected to develop. Notwithstanding the foregoing, the Purchaser may at any time transfer Purchased Units to an Affiliate of the Purchaser provided that any such transaction is exempt from registration under the Securities Act and that such Affiliate agrees to be bound by the terms and conditions of this Agreement.

Section 4.06     Nature of Purchaser . The Purchaser (a) is an “accredited investor” within the meaning of Rule 501 of Regulation D under the Securities Act and (b) by reason of its business and financial experience it has such knowledge, sophistication and experience in making similar investments and in business and financial matters generally so as to be capable of evaluating the merits and risks of the prospective investment in the Purchased Units, is able to bear the economic risk of such investment and, at the present time, would be able to afford a complete loss of such investment.

Section 4.07     Restricted Securities . The Purchaser understands that the Purchased Units are characterized as “restricted securities” under the federal securities Laws inasmuch as they are being acquired from SUN in a transaction not involving a public offering and that under such Laws such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, the Purchaser represents that it is knowledgeable with respect to Rule 144 under the Securities Act.

Section 4.08     Receipt of Information . The Purchaser has (a) had access to SUN’s periodic filings with the Commission and (b) been provided a reasonable opportunity to ask questions of and receive answers from Representatives of SUN regarding such matters.

Section 4.09     Legend . It is understood that the book-entry evidencing the Purchased Units will bear the following legend:

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND IS SUBJECT TO THE TERMS OF THE FIRST AMENDED AND RESTATED AGREEMENT OF LIMITED PARTNERSHIP, AS AMENDED, OF SUNOCO LP. THE HOLDER OF THIS SECURITY ACKNOWLEDGES FOR THE BENEFIT OF SUNOCO LP THAT THIS SECURITY MAY NOT BE SOLD, OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED IF SUCH TRANSFER WOULD (A) VIOLATE THE THEN APPLICABLE FEDERAL OR STATE SECURITIES LAWS OR RULES AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER GOVERNMENTAL AUTHORITY WITH JURISDICTION OVER SUCH TRANSFER, (B) TERMINATE THE EXISTENCE OR QUALIFICATION OF SUNOCO LP UNDER THE LAWS OF THE STATE OF DELAWARE, OR (C) CAUSE SUNOCO LP TO BE TREATED AS AN ASSOCIATION TAXABLE AS A CORPORATION OR OTHERWISE TO BE TAXED AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES (TO THE EXTENT NOT

13

ALREADY SO TREATED OR TAXED). SUNOCO GP LLC, THE GENERAL PARTNER OF SUNOCO LP, MAY IMPOSE ADDITIONAL RESTRICTIONS ON THE TRANSFER OF THIS SECURITY IF IT RECEIVES AN OPINION OF COUNSEL THAT SUCH RESTRICTIONS ARE NECESSARY TO AVOID A SIGNIFICANT RISK OF SUNOCO LP BECOMING TAXABLE AS A CORPORATION OR OTHERWISE BECOMING TAXABLE AS AN ENTITY FOR FEDERAL INCOME TAX PURPOSES. THE RESTRICTIONS SET FORTH ABOVE SHALL NOT PRECLUDE THE SETTLEMENT OF ANY TRANSACTIONS INVOLVING THIS SECURITY ENTERED INTO THROUGH THE FACILITIES OF ANY NATIONAL SECURITIES EXCHANGE ON WHICH THIS SECURITY IS LISTED OR ADMITTED TO TRADING.

14

consequential or punitive damages with respect to claims pursuant to this Section  6.01 .

The Purchaser agrees to indemnify SUN, the General Partner, and their respective Representatives (collectively, “ SUN Related Parties ”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Purchaser contained herein; provided, that such claim for indemnification relating to a breach of any representation or warranty is made prior to the expiration of the survival period for such representation or warranty, provided further, however, that the liability of the Purchaser shall not be greater in amount than the Purchase Price.

Section 6.03     Indemnification Procedure . Promptly after any SUN Related Party or Purchaser Related Party (hereinafter, the “ Indemnified Party ”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “ Indemnifying Party ”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure; provided, that, the failure to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which it may have to an Indemnified Party otherwise than under this Article VI . Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided , however , that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the

15

negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense and employ counsel or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrongdoing by, the Indemnified Party.

(c) Article V of the Partnership Agreement is hereby amended by adding a new Section 5.15 at the end thereof as follows:

“5.15. Establishment of Series A Preferred Units .

(a) Designations . A series of Units designated as “Series A Preferred Units” is hereby designated and created, and the preferences, rights, powers and duties of the holders of the Series A Preferred Units are set forth herein, including this Section 5.15. Each Series A Preferred Unit shall be identical in all respects to every other Series A Preferred Unit, except as to the respective dates from which the Series A Liquidation Preference (or Series A Early Liquidation Preference) shall increase or from which Series A Distributions may begin accruing, to the extent such dates may differ. The Series A Preferred Units represent perpetual equity interests in the Partnership and, except as set forth in Section 5.15(c), shall not give rise to a claim by the Partnership or the holders of Series A Preferred Units for redemption or the conversion thereof, as applicable, at a particular date.

(b) Rights of Series A Preferred Units . The Series A Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Initial Capital Account . The initial Capital Account balance with respect to each Series A Preferred Unit will be equal to the Series A Preferred Unit Issue Price.

(ii) Allocations .

(A) The holders of Series A Preferred Units shall not be entitled to receive, except as otherwise provided in this Section 5.15(b)(ii), allocations of (1) Net Income pursuant to Section 6.1(a), (2) Net Loss pursuant to Section 6.1(b), or (3) Net Termination Gains and Net Termination Losses pursuant to Section 6.1(c).

(B) For each taxable period, after the application of Section 6.1(b), Net Loss shall be allocated to the holders of Series A Preferred Units, in respect of the Series A Preferred Units, Pro Rata, until the Capital Account balance in respect of each Series A Preferred Unit has been reduced to zero.

8

(C) For each taxable period, after the application of Section 6.1(c)(ii)(C), the holders of Series A Preferred Units shall be allocated Net Termination Loss, Pro Rata, until the Capital Account balance in respect of each Series A Preferred Unit has been reduced to zero.

(D) For each taxable period, prior to the special allocations pursuant to Section 6.1(d) (other than Required Allocations):

(I) Items of Partnership gross income shall be allocated to the holders of Series A Preferred Units, Pro Rata, until the aggregate amount of gross income allocated to each holder of Series A Preferred Units pursuant hereto for the current taxable period and all previous taxable periods is equal to the cumulative amount of all cash distributions made with respect to such holder’s Series A Preferred Units pursuant to Section 5.15(b)(iii) from the date such Series A Preferred Units were issued to a date 60 days after the end of the current taxable period.

(II) Items of Partnership gross income, gain and Unrealized Gain shall be allocated to the holders of Series A Preferred Units, Pro Rata, until the aggregate amount of gross income, gain and Unrealized Gain allocated to each holder of Series A Preferred Units pursuant to this Section 5.15(b)(ii)(D)(II) for the current and all prior taxable periods is equal to the cumulative amount of all Net Losses allocated to such holder of Series A Preferred Units pursuant to Section 5.15(b)(ii)(B) for all previous taxable periods.

(III) If in the year of an event of any liquidation, dissolution or winding up of the Partnership, either voluntary or involuntary, and after having made all other allocations provided for in Sections 5.14(b)(v), 5.15(b)(ii) and 6.1 for the taxable period in which such liquidation, dissolution or winding up occurs, any holder’s Per Unit Capital Amount of each Series A Preferred Unit does not equal or exceed the Series A Liquidation Preference, then items of income, gain, loss and deduction for such taxable period shall be allocated among the Partners in a manner determined appropriate by the General Partner so as to cause, to the maximum extent possible, the Per Unit Capital Amount in respect of each Series A Preferred Unit to equal the Series A Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocations). If in the year of such liquidation, dissolution or winding up any such holder’s Capital Account in respect of such Series A Preferred Units is less than the

9

aggregate Series A Liquidation Preference of such Series A Preferred Units after the application of the preceding sentence, then to the extent permitted by law and notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable period(s) with respect to which Schedule K-1s have not been filed by the Partnership shall be reallocated to all Unitholders holding Series A Preferred Units, Pro Rata, until the Capital Account in respect of each Series A Preferred Unit then Outstanding is equal to the Series A Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If, after making the allocations provided for in this Section 5.15(b)(ii)(D)(III), the Series A Liquidation Preference exceeds the Per Unit Capital Amount in respect of each Series A Preferred Unit, the holders of Series A Preferred Units shall be entitled to receive, prior to the making of liquidating distributions pursuant to Section 12.4(c), a payment in the amount of such excess, which payment shall be treated for federal income tax purposes as a guaranteed payment for the use of capital under Section 707(c) of the Code.

(iii) Distributions . Commencing with and including the Series A Preferred Unit Issue Date, each Series A Preferred Unit shall accrue on a daily basis and be entitled to receive distributions payable in cash in an amount per Series A Preferred Unit equal to the Series A Preferred Unit Distribution Rate (each, a “ Series A Preferred Unit Quarterly Distribution ”), prior to distributions pursuant to Section 5.14(b)(vi) and any other distributions pursuant to Section 6.3, Section 6.4 or Section 6.5. Distributions shall be paid Quarterly, in arrears, within sixty (60) days after the end of each Quarter, commencing with the Quarter ending June 30, 2017. Each Record Date established for a Series A Preferred Unit Quarterly Distribution in respect of any Quarter shall be the same Record Date established for any distribution to be made by the Partnership in respect of other Partnership Interests pursuant to Section 6.3, Section 6.4 or Section 6.5 for such Quarter; provided, that if no such Record Date is established for other Partnership Interests for such Quarter, the Record Date for such Quarter shall be the forty-fifth day after the end of such Quarter (or, if such day is not a Business Day, the first Business Day thereafter). Each Series A Preferred Unit Quarterly Distribution (or, if applicable, portion thereof) for any Quarter that is payable in cash shall be paid in cash. If the Partnership fails to pay in full in cash any distribution (or portion thereof) which a holder of Series A Preferred Units accrues and is entitled to receive pursuant to this Section 5.15(b)(iii), then (x) the amount of such accrued and unpaid distributions will accumulate from and after the first date of such failure and continuing until such failure is cured by payment in full in cash of all accrued, accumulated and unpaid distributions (such accrued, accumulated and unpaid distributions, the “ Cumulative Series A Preferred Unit Arrearage ”) and (y) the Partnership shall not be permitted to, and shall not, declare or make (i) any distributions in respect of any other Units, other than

10

Series A Preferred Unit Quarterly Distributions, in respect of the Quarter in respect of which such Cumulative Series A Preferred Unit Arrearage first occurs or any subsequent Quarter, unless and until any and all Cumulative Series A Preferred Unit Arrearage has been paid in full in cash. For the avoidance of doubt, except as set forth in this Section 5.15(b)(iii), the Series A Preferred Units will not be entitled to receive distributions, including distributions of Available Cash under Section 6.3, Section 6.4 or Section 6.5.

(iv) Liquidation Preference .

At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the holders of the Series A Preferred Units shall become entitled to receive any accrued, accumulated and unpaid distributions in respect of the Series A Preferred Units, if any, to the date of dissolution (such accrued, accumulated and unpaid distributions shall include a partial distribution for the calendar Quarter in which such dissolution occurs equal to the product of (x) any distribution that would be payable to the holder of such Series A Preferred Unit if such Series A Preferred Unit were Outstanding on the Record Date for determining who would receive any distribution for such calendar quarter (calculated as of the date of dissolution) and (y) (A) the number of days commencing on the first day of such calendar Quarter and ending on the date of dissolution divided by (B) 90), and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the holders of the Series A Preferred Units to such accrued, accumulated and unpaid distributions shall have priority over any entitlement of any other Unitholders with respect to any distributions by the Partnership to such other Unitholders; provided , however , that the General Partner, as such, will have no liability for any obligations with respect to such distributions to the holders of the Series A Preferred Units.

(v) Voting Rights . Except as set forth in this Section 5.15(b)(v) and Section 13.3(c) and except to the extent the Delaware Act gives the Series A Preferred Units a vote as a class on any matter, the Series A Preferred Units shall not have any voting rights. With respect to any matter on which the Series A Preferred Units are entitled to vote, each Series A Preferred Unit will be entitled to one vote on such matter. The General Partner shall not, without the affirmative vote or written consent of holders of a majority of the Series A Preferred Units then Outstanding: (1) amend, alter, modify or change this Section 5.15(v) (or vote or consent or resolve to take such action), (2) adopt any amendment to this Agreement that would have a material adverse effect on the existing terms of the Series A Preferred Units, (3) create or issue any Parity Securities in the event there are Cumulative Series A Preferred Unit Arrearages, or (4) create or issue any Senior Securities.

(1) senior to the Junior Securities;

(2) on a parity with the Parity Securities;

(3) junior to the Senior Securities; and

(4) junior to all existing and future indebtedness and other liabilities of the Partnership with respect to assets available to satisfy claims against the Partnership.

The Partnership may issue Junior Securities and, subject to any approvals required by holders of Series A Preferred Units pursuant to Section 5.15(b)(v), Parity Securities from time to time in one or more classes or series without the consent of the holders of Series A Preferred Units.

(c) Optional Redemption .

(i) The Partnership shall have the right at any time, and from time to time, to redeem the Series A Preferred Units, in whole or in part, using any source of funds legally available for such purpose.

(iii) If the Partnership elects to redeem less than all of the Outstanding Series A Preferred Units, the number of Series A Preferred Units to be redeemed shall be determined by the Board of Directors, and shall be redeemed Pro Rata or by lot, with such adjustments to avoid redemption of fractional Series A Preferred Units. The Series A Preferred Units not redeemed shall remain Outstanding and entitled to all the rights and preferences provided in this Section 5.15.

(iv) If the Partnership gives or causes to be given a Series A Redemption Notice, the Partnership shall deposit with the Paying Agent funds, sufficient to redeem the Series A Preferred Units, as to which such Series A Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series A Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series A Redemption Price to the holders of Series A Preferred Units whose Series A Preferred Units are to be redeemed upon surrender or deemed surrender of the Series A Preferred Units therefor as set forth in the Series A Redemption Notice. If the Series A Redemption Notice shall have been given, from and after the Series A Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series A Redemption Notice, all distributions with respect to such Series A Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series A Preferred Units as Limited Partners with respect to such Series A Preferred Units to be redeemed, shall cease, except the right to receive the Series A Redemption Price, and such Series A Preferred Units be deemed to be Outstanding for any purpose whatsoever. The Partnership shall be entitled to receive from the Paying Agent the interest income, if any, earned on such funds deposited with the Paying Agent (to the extent that such interest income is not required to pay the Series A Redemption Price of the Series A Preferred Units to be redeemed), and the holders of any Series A Preferred Units so redeemed, shall

13

have no claim to any such interest income. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series A Preferred Units, that remain unclaimed or unpaid after two years after the applicable Series A Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the holders of Series A Preferred Units entitled to such redemption or other payment, shall have recourse only to the Partnership.

(v) Any Series A Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled.

(vi) Notwithstanding anything to the contrary in this Section 5.15, in the event that full cumulative cash distributions on the Series A Preferred Units shall not have been paid or declared and set apart for payment for any Quarter in respect of which Series A Preferred Units are Outstanding, none of the Partnership, the General Partner or any Affiliate of the General Partner shall be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series A Preferred Units except pursuant to a purchase or exchange offer made on the same relative terms to the holders of all of the Outstanding Series A Preferred Units.
