CASH DISTRIBUTIONS

Distributions of Available Cash

General. Our partnership agreement provides that we will distribute all of our available cash to unitholders of record on the applicable record date within 45 days after the end of each quarter. We intend to make distributions of available cash to the holders of common units on a quarterly basis, to the extent we have sufficient cash from our operations after establishment of cash reserves and payment of fees and expenses, and payments of distributions on certain of our other classes of units as described below. However, there is no guarantee that we will pay quarterly distributions on the common units in any quarter, and we will be prohibited from making any distributions to unitholders if it would cause an event of default, or an event of default is existing, under our credit facilities or debt securities.

Definition of Available Cash. Available cash generally means, for any calendar quarter, all cash on hand at the end of such quarter:

• less the amount of cash that the general partner determines in good faith is necessary or appropriate to:

• provide for the proper conduct of business;

• comply with applicable law, any of our debt instruments or other agreements; or

• provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters;

• plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

Working capital borrowings are generally borrowings that are made under our credit facilities and in all cases are used solely for working capital purposes or to pay distributions to partners.

Operating Surplus and Capital Surplus

General. All cash distributed to unitholders will be characterized as either “operating surplus” or “capital surplus.” We distribute available cash from operating surplus differently than available cash from capital surplus.

Definition of Operating Surplus. Operating surplus for any period generally means:

• our cash balance on the close date of our initial public offering; plus

• $15.0 million (as described below); plus

• all of our cash receipts after the closing of our initial public offering, excluding cash from borrowings that are not working capital borrowings, sales of equity and other debt securities and sales or other dispositions of assets outside the ordinary course of business; plus

• working capital borrowings made after the end of a quarter but before the date of determination of operating surplus for the quarter; plus

• an amount equal to the accumulated and undistributed operating surplus of Legacy ETP immediately prior to the closing of the merger between us and Legacy ETP (including $10.0 million of cash received from non-operating sources that Legacy ETP may distribute as operating surplus under the Legacy ETP partnership agreement in effect immediately prior to the merger); less

• all of our operating expenditures after the closing of our initial public offering, including the repayment of working capital borrowings, but not the repayment of other borrowings, and including maintenance capital expenditures; less

• the amount of cash reserves established by the general partner in good faith to provide funds for future operating expenditures.

S-5

Definition of Capital Surplus. Capital surplus will generally be generated only by:

• borrowings other than working capital borrowings;

• sales of debt and equity securities; and

• sales or other dispositions of assets for cash, other than inventory, accounts receivable and other current assets sold in the ordinary course of business or as part of normal retirements or replacements of assets.

Characterization of Cash Distributions. We will treat all available cash distributed as coming from operating surplus until the sum of all available cash distributed since we began operations equals the operating surplus as of the most recent date of determination of available cash. We will treat any amount distributed in excess of operating surplus, regardless of its source, as capital surplus. As reflected above, operating surplus includes $15.0 million in addition to our cash balance on the closing date of our initial public offering, cash receipts from our operations, cash from working capital borrowings and the undistributed operating surplus of Legacy ETP as of the date of the merger.

Distributions of Available Cash from Operating Surplus

We will make distributions of available cash from operating surplus for any quarter in the following manner:

• First, 100% to all common unitholders and the general partner, in accordance with their percentage interests, until each common unit has received $0.075 per common unit for such quarter, also known as the minimum quarterly distribution;

• Second, 100% to all common unitholders and the general partner, in accordance with their respective percentage interests, until each common unit has received $0.0833 per common unit for such quarter, also known as the first target distribution; and

• Thereafter, in the manner described in “— Incentive Distribution Rights” below.

Our partnership agreement provides that our Class E units and our Class G units participate in the distributions of available cash and receive their respective percentage interests. Notwithstanding the foregoing, the distributions on each of our Class E units may not exceed $1.41 per year and distributions on each of our Class G units may not exceed $3.75 per year. In addition, the distributions to the holders of the incentive distribution rights will not exceed the amount holders of the incentive distribution rights would otherwise receive if the available cash for distribution were reduced to the extent it constitutes amounts previously distributed with respect to our Class G units.

Our partnership agreement also provides that our Class K units do not have a percentage interest and holders are not entitled to receive distributions of cash from operating surplus or capital surplus; however prior to us making any distribution of available cash to any class of units other than the Class I units, each Class K unit is entitled to a quarterly cash distribution in an amount equal to $0.67275 per Class K unit; provided, however, no portion of any partnership cash distribution attributable to (i) any distribution or dividend received by us from Holdco (as defined in our partnership agreement) or the proceeds of any sale of the capital stock of Holdco or (ii) any Holdco Distributions (as defined in our partnership agreement).

Incentive Distribution Rights

Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution has been paid. Our general partner currently holds all of the incentive distribution rights, but may transfer these rights separately from its general partner interest, subject to restrictions in the partnership agreement.

S-6

If for any quarter we have distributed available cash from operating surplus to the unitholders in an amount equal to the minimum quarterly distribution, then, we will distribute any additional available cash from operating surplus for that quarter among the unitholders and the general partner in the following manner:

• First, (i) to the general partner in accordance with its percentage interest, (ii) 13% to the holders of the incentive distribution rights, pro rata, and (iii) to all of our common unitholders, Class E unitholders and Class G unitholders, pro rata, a percentage equal to 100% less the percentages applicable to the general partner and holders of the incentive distribution rights, until each of our common unit has received $0.0958 per unit for such quarter, also known as the second target distribution;

• Second, (i) to the general partner in accordance with its percentage interest, (ii) 35% to the holders of the incentive distribution rights, pro rata, and (iii) to all of our common unitholders, Class E unitholders and Class G unitholders, pro rata, a percentage equal to 100% less the percentages applicable to the general partner and holders of the incentive distribution rights, until each of our common units has received $0.2638 per unit for such quarter, also known as the third target distribution; and

• Thereafter, (i) to the general partner in accordance with its percentage interest, (ii) 48% to the holders of the incentive distribution rights, pro rata, and (iii) to all of our common unitholders, Class E unitholders and Class G unitholders, pro rata, a percentage equal to 100% less the percentages applicable to the general partner and holders of the incentive distribution rights.

Percentage Allocations of Available Cash from Operating Surplus

The following table illustrates the percentage allocations of the additional available cash from operating surplus between our unitholders and our general partner up to the various target distribution levels.

The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Target Amount,” until available cash from operating surplus we distribute reaches the next target distribution level, if any.

The percentage interests shown for the unitholders and the general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution.

			Marginal Percentage Interest in Distributions
	Total Quarterly Distribution Target		Unitholders			General Partner(1)
Minimum Quarterly Distribution	$	0.075		99.61	%		0.39	%
First Target Distribution	up to $	0.0833		99.61	%		0.39	%
Second Target Distribution	up to $	0.0958		86.61	%		13.39	%
Third Target Distribution	up to $	0.2638		64.61	%		35.39	%
Thereafter	above $	0.2638		51.61	%		48.33	%

(1) Assumes the general partner maintains its current 0.39% general partner interest.

Distributions from Capital Surplus

We will make distributions of available cash from capital surplus, if any, in the following manner:

• First, to all unitholders and our general partner, in accordance with their respective percentage interests, until we distribute for each outstanding common unit, an amount of available cash from capital surplus equal to the initial public offering price of our common units; and

• Thereafter, we will make all distributions of available cash from capital surplus as if they were from operating surplus.

S-7

The partnership agreement treats a distribution of capital surplus as the repayment of the initial unit price from the initial public offering, which is a return of capital. The initial public offering price less any distributions of capital surplus per unit is referred to as the “unrecovered initial unit price.”

Adjustment to the Minimum Quarterly Distribution and Target Distribution Levels

If we combine our units into fewer units or subdivide our units into a greater number of units, we will proportionately adjust:

• the minimum quarterly distribution;

• target distribution levels; and

• unrecovered initial unit price.

For example, if a two-for-one split of the common units should occur, the minimum quarterly distribution, the target distribution levels and the unrecovered initial unit price would each be reduced to 50% of its initial level. We will not make any adjustment by reason of the issuance of additional units for cash or property.

In addition, if legislation is enacted or if existing law is modified or interpreted in a manner that causes us to become taxable as a corporation or otherwise subject to taxation as an entity for federal, state or local income tax purposes, we will reduce the minimum quarterly distribution and the target distribution levels by multiplying the same by one minus the sum of the highest marginal federal corporate income tax rate that could apply and any increase in the effective overall state and local income tax rates.

Distributions of Cash Upon Liquidation

General. If we dissolve in accordance with the partnership agreement, we will sell or otherwise dispose of our assets in a process called liquidation. We will first apply the proceeds of liquidation to the payment of our creditors. We will distribute any remaining proceeds to the unitholders, in accordance with their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of our assets in liquidation.

Manner of Adjustments for Gain. The manner of the adjustment for gain is set forth in our partnership agreement. We generally allocate any gain to the partners in the following manner:

• First, to our general partner and the holders of units who have negative balances in their capital accounts to the extent of and in proportion to any such negative balances;

• Second, to the unitholders and our general partner, in accordance with their percentage interests, until the capital account for each common unit is equal to the sum of:

• the unrecovered initial unit price; and

• the amount of the minimum quarterly distribution for the quarter during which our liquidation occurs.

• Third, to the unitholders and our general partner, in accordance with their percentage interests, until we allocate under this paragraph an amount per unit equal to:

• the sum of the excess of the first target distribution per unit over the minimum quarterly distribution per unit for each quarter of our existence; less

• the cumulative amount per unit of any distributions from operating surplus in excess of the minimum quarterly distribution per unit for each quarter of our existence distributed to the unitholders and to our general partner in accordance with their percentage interests;

S-8

• Fourth, 13% to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata, until we allocate under this paragraph an amount per unit equal to:

• the sum of the excess of the second target distribution per unit over the first target distribution per unit for each quarter of our existence; less

• the cumulative amount per unit of any distributions from operating surplus in excess of the first target distribution per unit for each quarter of our existence distributed 13% to the holders of the incentive distribution rights, pro rata, and the remainder to our unitholders and to our general partner in accordance with their percentage interests, pro rata;

• Fifth, 23% to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata, until we allocate under this paragraph an amount per unit equal to:

• the sum of the excess of the third target distribution per unit over the second target distribution per unit for each quarter of our existence; less

• the cumulative amount per unit of any distributions from operating surplus in excess of the second target distribution per unit for each quarter of our existence distributed to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata; and

• Thereafter, 48% to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata.

Adjustments to Capital Accounts upon the Issuance of Partnership Interests

We will make adjustments to capital accounts upon the issuance of additional partnership interests. In doing so, we will allocate any unrealized and, for tax purposes, unrecognized gain or loss resulting from the adjustments to the unitholders and our general partner in the same manner as we allocate gain or loss upon liquidation. In the event that we make positive adjustments to the capital accounts upon the issuance of additional partnership interests, we will allocate any later negative adjustments to the capital accounts resulting from the issuance of additional partnership interests or upon our liquidation in a manner that results, to the extent possible, in our general partner’s capital account balances equaling the amount that they would have been if no earlier positive adjustments to the capital accounts had been made.

S-9

DESCRIPTION OF THE COMMON UNITS

Unlike the holders of common stock in a corporation, our limited partners have only limited voting rights on matters affecting our business. Our limited partners have no right to elect our general partner or the directors of our general partner on an annual or other continuing basis.

Limited Call Right

If at any time our general partner and its affiliates hold more than 80% of the total limited partner interests of any class then outstanding, our general partner will then have the right, which right it may assign and transfer in whole or in part to us or any affiliate of our general partner, exercisable at its option, to purchase all, but not less than all, of such limited partner interests of such class then outstanding held by persons other than our general partner and its affiliates.

Transfer Agent and Registrar Duties

American Stock Transfer & Trust Company serves as registrar and transfer agent for our common units. We pay all fees charged by the transfer agent for transfers of common units, except the following that must be paid by unitholders:

• surety bond premiums to replace lost or stolen certificates, taxes and other governmental charges;

• special charges for services requested by a holder of common units; and

• other similar fees or charges.

There is no charge to unitholders for disbursements of our cash distributions. We will indemnify the transfer agent, its agents and each of their stockholders, directors, officers and employees against all claims and losses that may arise out of acts performed or omitted for its activities as transfer agent, except for any liability due to any gross negligence or intentional misconduct of the indemnified person or entity.

Transfer of Common Units

Any transfers of a common unit will not be recorded by the transfer agent or recognized by us unless the transferee executes and delivers a transfer application. By executing and delivering a transfer application, the transferee of common units:

• becomes the record holder of the common units and is an assignee until admitted as a substituted limited partner;

• automatically requests admission as a substituted limited partner;

• agrees to comply with and be bound by and to have executed our partnership agreement;

• represents and warrants that such transferee has the right, power and authority and, if an individual, the capacity to enter into our partnership agreement;

• grants the powers of attorney set forth in our partnership agreement; and

• gives the consents and approvals and makes the waivers contained in our partnership agreement.

An assignee will become a substituted limited partner for the transferred common units upon the consent of our general partner and the recording of the name of the assignee on our books and records. Our general partner may withhold its consent in its sole discretion.

A transferee’s broker, agent or nominee may complete, execute and deliver a transfer application. We are entitled to treat the nominee holder of a common unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely to those that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.

Common units are securities and are transferable according to the laws governing transfer of securities. In addition to other rights acquired upon admission as a substituted limited partner for the transferred common units, a purchaser or transferee of common units who does not execute and deliver a transfer application obtains only:

• the right to assign the common units to a purchaser or other transferee; and

• the right to transfer the right to seek admission as a substituted limited partner for the transferred common units.

Thus, a purchaser or transferee of common units who does not execute and deliver a transfer application:

• will not receive cash distributions or federal income tax allocations, unless the common units are held in a nominee or “street name” account and the nominee or broker has executed and delivered a transfer application; and

• may not receive some federal income tax information or reports furnished to record holders of common units.

S-11

The transferor of common units has a duty to provide the transferee with all information that may be necessary to transfer the common units. The transferor does not have a duty to insure the execution of the transfer application by the transferee and has no liability or responsibility if the transferee neglects or chooses not to execute and forward the transfer application to the transfer agent.

Until a common unit has been transferred on our books, we and the transfer agent may treat the record holder of the common unit as the absolute owner for all purposes, except as otherwise required by law or stock exchange regulations.

S-12

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The tax consequences to you of an investment in our common units will depend in part on your own tax circumstances. Although this section updates and adds information related to certain tax considerations, it should be read in conjunction with the risk factors in our most recent Annual Report on Form 10-K, and with “Material U.S. Federal Income Tax Consequences” in the accompanying prospectus, which provides a discussion of the principal federal income tax considerations associated with our operations and the purchase, ownership and disposition of our common units. The following discussion is limited as described under the caption “Material U.S. Federal Income Tax Consequences” in the accompanying prospectus.

All prospective unitholders are encouraged to consult with their own tax advisors about the federal, state, local and foreign tax consequences particular to their own circumstances. In particular, ownership of common units by tax-exempt entities, including employee benefit plans and IRAs, and non-U.S. investors raises issues unique to such persons. The relevant rules are complex, and the discussions herein and in the accompanying prospectus do not address tax considerations applicable to tax-exempt entities and non-U.S. investors, except as specifically set forth in the accompanying prospectus. Please read “Material U.S. Federal Income Tax Consequences—Tax-Exempt Organizations and Other Investors” in the accompanying prospectus.

Taxation of the Partnership

Allocations Between Transferors and Transferees

In general, our taxable income or loss will be determined annually, will be prorated on a monthly basis and will be subsequently apportioned among the unitholders in proportion to the number of units owned by each of them as of the opening of the applicable exchange on the first business day of the month (the “Allocation Date”). Nevertheless, we allocate certain deductions for depreciation of capital additions based upon the date the underlying property is placed in service, and gain or loss realized on a sale or other disposition of our assets or, in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction will be allocated among the unitholders on the Allocation Date in the month in which such income, gain, loss or deduction is recognized. As a result, a unitholder transferring units may be allocated income, gain, loss and deduction realized after the date of transfer.

Although simplifying conventions are contemplated by the Code and most publicly traded partnerships use similar simplifying conventions, existing Treasury Regulations do not specifically authorize the use of the proration method we have adopted. Accordingly, Vinson & Elkins L.L.P. is unable to opine on the validity of this method of allocating income and deductions between transferee and transferor unitholders. If the IRS determines that this method is not allowed under the Treasury Regulations our taxable income or losses could be reallocated among our unitholders. Under our partnership agreement, we are authorized to revise our method of allocation between transferee and transferor unitholders, as well as among unitholders whose interests vary during a taxable year, to conform to a method permitted under the Treasury Regulations.

A unitholder who disposes of units prior to the record date set for a cash distribution for that quarter will be allocated items of our income, gain, loss and deduction attributable to the month of disposition but will not be entitled to receive a cash distribution for that period.

Legislation Affecting the Tax Treatment of Publicly Traded Partnerships

The present federal income tax treatment of publicly traded partnerships, including us, or an investment in our units may be modified by administrative or legislative action or judicial interpretation at any time. From time to time, members of the U.S. Congress propose and consider substantive changes to the existing federal income tax laws that affect publicly-traded partnerships. One such legislative proposal would have eliminated the Qualifying Income Exception upon which we rely for our treatment as a partnership for federal income tax purposes.

S-13

On January 24, 2017, final regulations regarding which activities give rise to qualifying income (the “Final Regulations”) were published in the Federal Register. The Final Regulations are effective as of January 19, 2017, and apply to taxable years beginning on or after January 19, 2017. We do not believe the Final Regulations affect our ability to qualify as a publicly traded partnership.

Administrative Matters

Information Returns and Audit Procedures

Pursuant to the Bipartisan Budget Act of 2015, for taxable years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns, it may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us, unless we elect to have our general partner and unitholders take any audit adjustment into account in accordance with their interests in us during the taxable year under audit. Similarly, for such taxable years, if the IRS makes audit adjustments to income tax returns filed by an entity in which we are a member or partner, it may assess and collect any taxes (including penalties and interest) resulting from such audit adjustment directly from such entity. Generally, we expect to elect to have our general partner and unitholders take any such audit adjustment into account in accordance with their interests in us during the taxable year under audit, but there can be no assurance that such election will be effective in all circumstances. With respect to audit adjustments as to an entity in which we are a member or partner, the Joint Committee of Taxation has stated that we would not be able to have our general partner and our unitholders take such audit adjustment into account. If we are unable to have our general partner and our unitholders take such audit adjustment into account in accordance with their interests in us during the taxable year under audit, our then current unitholders may bear some or all of the tax liability resulting from such audit adjustment, even if such unitholders did not own our units during the taxable year under audit. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties, and interest, our cash available for distribution to our unitholders might be substantially reduced. These rules are not applicable for taxable years beginning on or prior to December 31, 2017. Congress has proposed changes to the Bipartisan Budget Act, and we anticipate that amendments may be made. Accordingly, the manner in which these rules may apply to us in the future is uncertain.

Additionally, pursuant to the Bipartisan Budget Act of 2015, the Code will no longer require that we designate a Tax Matters Partner. Instead, for taxable years beginning after December 31, 2017, we will be required to designate a partner, or other person, with a substantial presence in the United States as the partnership representative (“Partnership Representative”). The Partnership Representative will have the sole authority to act on our behalf for purposes of, among other things, federal income tax audits and judicial review of administrative adjustments by the IRS. If we do not make such a designation, the IRS can select any person as the Partnership Representative. We currently anticipate that we will designate our general partner as the Partnership Representative. Further, any actions taken by us or by the Partnership Representative on our behalf with respect to, among other things, federal income tax audits and judicial review of administrative adjustments by the IRS, will be binding on us and all of the unitholders.

Additional Withholding Requirements

Withholding taxes may apply to certain types of payments made to “foreign financial institutions” (as specially defined in the Code) and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on interest, dividends and other fixed or determinable annual or periodical gains, profits and income from sources within the United States (“FDAP Income”), or gross proceeds from the sale or other disposition of any property of a type which can produce interest or dividends from sources within the United States (“Gross Proceeds”) paid to a foreign financial institution or to a “non-financial foreign entity” (as specially defined in the Code), unless (i) the foreign financial institution undertakes certain diligence and reporting, (ii) the non-financial foreign entity either certifies it does not have any substantial U.S. owners or furnishes identifying information regarding each substantial U.S. owner or (iii) the foreign financial institution or non-financial foreign entity

S-14

otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (i) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain U.S. persons or U.S.-owned foreign entities, annually report certain information about such accounts, and withhold 30% on payments to noncompliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing these requirements may be subject to different rules.

These rules generally apply to payments of FDAP Income currently and generally will apply to payments of relevant Gross Proceeds made on or after January 1, 2019. Thus, to the extent we have FDAP Income or we have Gross Proceeds on or after January 1, 2019 that are not treated as effectively connected with a U.S. trade or business (please read “—Tax-Exempt Organizations and Other Investors”), a unitholder who is foreign financial institution or certain other non-U.S. entity, or a person that hold its units through such foreign entities, may be subject to withholding on distributions they receive from us, or its distributive share of our income, pursuant to the rules described above.

Each prospective unitholder should consult its own tax advisors regarding the potential application of these withholding provisions to its investment in our units.

S-15

PLAN OF DISTRIBUTION

We have entered into an equity distribution agreement with UBS Securities LLC, Barclays Capital Inc., BNP Paribas Securities Corp., Citigroup Global Markets Inc., Credit Agricole Securities (USA) Inc., Deutsche Bank Securities Inc., Fifth Third Securities, Inc., Goldman Sachs & Co. LLC, HSBC Securities (USA) Inc., Jefferies LLC, J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated, Mizuho Securities USA LLC, Morgan Stanley & Co. LLC, MUFG Securities Americas Inc., Natixis Securities Americas LLC, RBC Capital Markets, LLC, Scotia Capital (USA) Inc., SMBC Nikko Securities America, Inc., SunTrust Robinson Humphrey, Inc., TD Securities (USA) LLC, USCA Securities LLC and Wells Fargo Securities, LLC as our sales agents, under which we may offer and sell common units having an aggregate offering price of up to $1,000,000,000 from time to time. Sales of the common units, if any, will be made by means of ordinary brokers’ transactions on the NYSE at market prices, block transactions and such other transactions as agreed upon by us and the sales agents. The sales agents will not engage in any transactions that stabilize the price of our common units.

Under the terms of the equity distribution agreement, we also may sell common units to one or more of the sales agents as principal for its own account at a price agreed upon at the time of the sale. If we sell common units to a sales agent as principal, we will enter into a separate terms agreement with the sales agent, and we will describe that agreement in a separate prospectus supplement or pricing supplement.

The sales agents will use their commercially reasonable efforts to sell the common units offered pursuant to this prospectus supplement on a daily basis or as otherwise agreed upon by us and a sales agent. We will designate the maximum number of common units to be sold through a sales agent, on a daily basis or otherwise as we and a sales agent agree. We will submit orders to only one sales agent relating to the sale of our common units on any given day. We may instruct such sales agent not to sell common units if the sales cannot be effected at or above the price designated by us in any such instruction. Either we or any sales agent may suspend the offering of common units by such sales agent pursuant to the equity distribution agreement by notifying the other party.

The commission to be paid to any sales agent for common units sold through it pursuant to the equity distribution agreement shall be fixed at a commission rate of up to 2.0% of the gross sales price per common unit. The remaining sales proceeds, after deducting the applicable commission and any expenses payable by us and any transaction fees imposed by any governmental or self-regulatory organization in connection with the sales, will equal our net proceeds from the sale of the common units.

Settlement for sales of common units will occur on the third business day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sale of the common units on our behalf, the sales agents may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, as amended, or the Securities Act, and the compensation paid to the sales agents may be deemed to be underwriting commissions or discounts. We have agreed to provide indemnification and contribution to the sales agents against certain liabilities, including civil liabilities under the Securities Act. We have also agreed to reimburse the sales agents for certain of their expenses.

The sales agents and their related entities have, from time to time, performed, and may in the future perform, various financial advisory and commercial and investment banking services for us and our affiliates, for which they have received and in the future will receive customary compensation and expense reimbursement.

In addition, in the ordinary course of their business activities, the sales agents and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own accounts and for the accounts of their customers.

S-16

Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any sales agent or any of its affiliates has a lending relationship with us, one or more of the sales agents or such affiliates may hedge their credit exposure to us consistent with their customary risk management policies.

Typically, such sales agents and such affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the common units offered hereby. Any such short positions could adversely affect future trading prices of the common units offered hereby. The sales agents and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

In compliance with the guidelines of the Financial Industry Regulatory Authority, Inc., or FINRA, the maximum discount or commission to be received by any FINRA member or independent broker-dealer may not exceed 8% of the aggregate offering price of the common units offered pursuant to this prospectus supplement. We intend to use a portion of the proceeds of this offering to repay amounts outstanding under our revolving credit facility. Affiliates of certain of the sales agents are lenders under our revolving credit facility and, accordingly, may receive a portion of the net proceeds of this offering. Because FINRA views the common units offered hereby as interests in a direct participation program, this offering is being made in compliance with Rule 2310 of the FINRA Rules.

If we or any of the sales agents have reason to believe that our common units are no longer an “actively-traded security” as defined under Rule 101(c)(l) of Regulation M under the Securities Exchange Act of 1934, as amended, that party will promptly notify the other and sales of common units pursuant to the equity distribution agreement or any terms agreement will be suspended until in our collective judgment Rule 101(c)(1) or another exemptive provision has been satisfied.

The offering of common units pursuant to the equity distribution agreement will terminate upon the earlier of (1) the sale of all common units subject to the equity distribution agreement or (2) the termination of the equity distribution agreement by us or by all of the sales agents.

S-17

RISK FACTORS

Limited partner interests are inherently different from the capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in a similar business. An investment in our common units involves risks. Before you invest in our common units, you should carefully consider the risk factors included in our most recent Annual Report on Form 10-K, subsequent Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, which are incorporated herein by reference, and those risk factors that may be included in the applicable prospectus supplement, together with all of the other information contained in or incorporated by reference into this prospectus or any prospectus supplement as provided under “Incorporation by Reference.” This prospectus also contains forward-looking statements that involve risks and uncertainties. Please read “Forward-Looking Statements.”

If any of these risks were to materialize, our business, financial condition, results of operations, cash flows or prospects could be adversely affected. In that case, our ability to make distributions to our unitholders may be reduced, the trading price of our common units could decline and you could lose all or part of your investment.

5

FORWARD-LOOKING STATEMENTS

Certain statements, other than statements of historical fact, included or incorporated by reference into this prospectus and any accompanying prospectus supplement constitute “forward-looking” statements. These forward-looking statements discuss our goals, intentions and expectations as to future trends, plans, events, results of operations or financial condition, or state other information relating to us, based on the current beliefs of our management as well as assumptions made by, and information currently available to, our management. Words such as “may,” “anticipates,” “believes,” “expects,” “estimates,” “planned,” “intends,” “projects,” “scheduled” or similar phrases or expressions identify forward-looking statements. When considering forward-looking statements, you should keep in mind the risk factors and other cautionary statements in this prospectus, any accompanying prospectus supplement and the documents we incorporate by reference.

Although we believe these forward-looking statements are reasonable, they are based upon a number of assumptions, any or all of which may ultimately prove to be inaccurate. These statements are also subject to numerous assumptions, uncertainties and risks that may cause future results to be materially different from the results projected, forecasted, estimated or budgeted, including, but not limited to, the following:

• Our ability to successfully consummate announced acquisitions or expansions and integrate them into our existing business operations;

• Delays related to construction of, or work on, new or existing facilities and the issuance of applicable permits;

• Changes in the supply of, or demand for crude oil, NGLs and refined products that impact demand for our pipeline, terminalling and storage services;

• Changes in the short-term and long-term demand for crude oil, NGLs and refined products we buy and sell;

• An increase in the competition encountered by our terminals, pipelines and acquisition and marketing operations;

• Changes in the financial condition or operating results of joint ventures or other holdings in which we have an equity ownership interest;

• Changes in the general economic conditions in the United States;

• Changes in laws and regulations to which we are subject, including federal, state, and local tax, safety, environmental and employment laws;

• Changes in regulations governing the composition of the products that we transport, terminal and store;

• Improvements in energy efficiency and development of technology resulting in reduced demand for refined petroleum products;

• Our ability to manage growth and/or control costs;

• The effect of changes in accounting principles and tax laws, and interpretations of both;

• Global and domestic economic repercussions, including disruptions in the crude oil, NGLs and refined products markets, from terrorist activities, international hostilities and other events, and the government’s response thereto;

• Changes in the level of operating expenses and hazards related to operating our facilities (including equipment malfunction, explosions, fires, spills and the effects of severe weather conditions);

• The occurrence of operational hazards or unforeseen interruptions for which we may not be adequately insured;

• The age of, and changes in the reliability and efficiency of our operating facilities;

6

• Changes in the expected level of capital, operating, or remediation spending related to environmental matters;

• Changes in insurance markets resulting in increased costs and reductions in the level and types of coverage available;

• Risks related to labor relations and workplace safety;

• Non-performance by or disputes with major customers, suppliers or other business partners;

• Changes in our tariff rates implemented by federal and/or state government regulators;

• The amount of our debt, which could make us vulnerable to adverse general economic and industry conditions, limit our ability to borrow additional funds, place us at competitive disadvantages compared to competitors that have less debt, or have other adverse consequences;

• Restrictive covenants in our credit agreements;

• Changes in our or our general partner’s credit ratings, as assigned by ratings agencies;

• The condition of the debt and equity capital markets in the United States, and our ability to raise capital in a cost-effective way;

• Performance of financial institutions impacting our liquidity, including those supporting our credit facilities;

• The effectiveness of our risk management activities, including the use of derivative financial instruments to hedge commodity risks;

• Changes in interest rates on our outstanding debt, which could increase the costs of borrowing; and

• The costs and effects of legal and administrative claims and proceedings against us or any entity in which we have an ownership interest, and changes in the status of, or the initiation of new litigation, claims or proceedings, to which we, or any entity in which we have an ownership interest, are a party.

These factors are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors could also have material adverse effects on future results. We undertake no obligation to update publicly any forward-looking statement, whether as a result of new information or future events.

USE OF PROCEEDS

Unless we specify otherwise in any prospectus supplement, we will use the net proceeds (after the payment of offering expenses and underwriting discounts and commissions) from our sale of common units for general partnership purposes, which may include, among other things:

• paying or refinancing all or a portion of our indebtedness outstanding at the time; and

• funding working capital, capital expenditures or acquisitions (which may consist of acquisitions of discrete assets or businesses).

The actual application of proceeds from the sale of any particular offering of common units using this prospectus will be described in the applicable prospectus supplement relating to such offering. The precise amount and timing of the application of these proceeds will depend upon our funding requirements and the availability and cost of other funds.

DESCRIPTION OF THE COMMON UNITS

Our common units represent limited partner interests that entitle the holders to participate in our cash distributions and to exercise the rights and privileges available to limited partners under our Third Amended and Restated Agreement of Limited Partnership, as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4, Amendment No. 5 and Amendment No. 6 thereto (as amended, our “partnership agreement”). For a description of the rights of holders of our common units to cash distributions, please read “Cash Distributions” in this prospectus. For a description of the rights and privileges of limited partners under our partnership agreement, including voting rights, please read “Description of Our Partnership Agreement” in this prospectus. We urge you to read our partnership agreement, as our partnership agreement, and not this description, governs our common units.

Number of Common Units

As of August 4, 2016, we had 297,903,172 common units and 9,416,196 Class B Units outstanding; 230,841,898 common units are held by the public and 67,061,274 common units and all of our Class B Units are held by ETP, which is the controlling owner of our general partner. The Class B Units will automatically convert to common units on a one-to-one basis on July 11, 2017, subject to our right to call the Class B Units and ETP’s right to sell the Class B Units to us pursuant to that certain Unitholder Agreement, dated as of October 8, 2015. The common units and Class B Units represent an aggregate approximately 99% limited partner interest in us and the general partner interest held by our general partner represents an approximately 1% general partner interest in us.

Timing of Distributions

We pay distributions no later than 45 days after March 31, June 30, September 30 and December 31 to holders of record on the applicable record date. For additional information, please read “Cash Distributions.”

Issuance of Additional Partnership Securities; Preemptive Rights

In general, we may issue additional partnership securities for any partnership purpose at any time and from time to time to such persons for such consideration and on such terms and conditions as shall be established by our general partner in its sole discretion, all without the approval of any limited partners. The holders of our common units do not have preemptive rights to acquire additional common units or other partnership securities. For additional information, please read “Description of Our Partnership Agreement—Issuance of Additional Partnership Securities; Preemptive Rights.”

Voting Rights

Unlike the holders of common stock in a corporation, our limited partners have only limited voting rights on matters affecting our business. Our limited partners have no right to elect our general partner or the directors of our general partner on an annual or other continuing basis. Our general partner may not be removed except by the vote of the holders of at least 66 ²/₃% of the outstanding units, including units owned by our general partner and its affiliates. Each holder of units is entitled to one vote for each unit on all matters submitted to a vote of the unitholders. For additional information, please read “Description of Our Partnership Agreement—Meetings; Voting.”

Limited Call Right

If at any time our general partner and its affiliates hold more than 80% of the total limited partner interests of any class then outstanding, our general partner will then have the right, which right it may assign and transfer in whole or in part to us or any affiliate of our general partner, exercisable at its option, to purchase all, but not

9

less than all, of such limited partner interests of such class then outstanding held by persons other than our general partner and its affiliates. For additional information, please read “Description of Our Partnership Agreement—Limited Call Right.”

Exchange Listing

Our common units are listed on the New York Stock Exchange under the symbol “SXL.”

Transfer Agent and Registrar Duties

American Stock Transfer & Trust Company serves as registrar and transfer agent for our common units. We pay all fees charged by the transfer agent for transfers of common units, except the following that must be paid by unitholders:

• surety bond premiums to replace lost or stolen certificates, taxes and other governmental charges;

• special charges for services requested by a holder of common units; and

• other similar fees or charges.

There is no charge to unitholders for disbursements of our cash distributions. We will indemnify the transfer agent, its agents and each of their stockholders, directors, officers and employees against all claims and losses that may arise out of acts performed or omitted for its activities as transfer agent, except for any liability due to any gross negligence or intentional misconduct of the indemnified person or entity.

Transfer of Common Units

Any transfers of a common unit will not be recorded by the transfer agent or recognized by us unless the transferee executes and delivers a transfer application. By executing and delivering a transfer application, the transferee of common units:

• becomes the record holder of the common units and is an assignee until admitted as a substituted limited partner;

• automatically requests admission as a substituted limited partner;

• agrees to comply with and be bound by and to have executed our partnership agreement;

• represents and warrants that such transferee has the right, power and authority and, if an individual, the capacity to enter into our partnership agreement;

• grants the powers of attorney set forth in our partnership agreement; and

• gives the consents and approvals and makes the waivers contained in our partnership agreement.

An assignee will become a substituted limited partner for the transferred common units upon the consent of our general partner and the recording of the name of the assignee on our books and records. Our general partner may withhold its consent in its sole discretion.

A transferee’s broker, agent or nominee may complete, execute and deliver a transfer application. We are entitled to treat the nominee holder of a common unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely to those that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.

Common units are securities and are transferable according to the laws governing transfer of securities. In addition to other rights acquired upon admission as a substituted limited partner for the transferred common units, a purchaser or transferee of common units who does not execute and deliver a transfer application obtains only:

• the right to assign the common units to a purchaser or other transferee; and

10

• the right to transfer the right to seek admission as a substituted limited partner for the transferred common units.

Thus, a purchaser or transferee of common units who does not execute and deliver a transfer application:

• will not receive cash distributions or federal income tax allocations, unless the common units are held in a nominee or “street name” account and the nominee or broker has executed and delivered a transfer application; and

• may not receive some federal income tax information or reports furnished to record holders of common units.

The transferor of common units has a duty to provide the transferee with all information that may be necessary to transfer the common units. The transferor does not have a duty to insure the execution of the transfer application by the transferee and has no liability or responsibility if the transferee neglects or chooses not to execute and forward the transfer application to the transfer agent.

Until a common unit has been transferred on our books, we and the transfer agent may treat the record holder of the common unit as the absolute owner for all purposes, except as otherwise required by law or stock exchange regulations.

CASH DISTRIBUTIONS

Distributions of Available Cash

General. Our partnership agreement provides that we will distribute all of our available cash to unitholders of record on the applicable record date within 45 days after the end of each quarter.

Definition of Available Cash. Available cash generally means, for each fiscal quarter:

• all cash on hand at the end of the quarter;

• less the amount of cash reserves that our general partner establishes to:

• provide for the proper conduct of our business;

• comply with applicable law, any of our debt instruments or other agreements; or

• provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters;

• plus all cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

Working capital borrowings are generally borrowings that are made under our credit facilities and in all cases are used solely for working capital purposes or to pay distributions to partners.

Intent to Distribute the Minimum Quarterly Distribution. We intend to distribute to the holders of common units on a quarterly basis at least the minimum quarterly distribution of $0.075 per unit, or $0.30 per year, to the extent we have sufficient cash from our operations after establishment of cash reserves and payment of fees and expenses, including payments to our general partner. However, there is no guarantee that we will pay the quarterly distribution in this amount, or the minimum quarterly distribution on the common units in any quarter, and we will be prohibited from making any distributions to unitholders if it would cause an event of default, or an event of default is existing, under our credit facilities or the debt securities.

Operating Surplus and Capital Surplus

General. All cash distributed to unitholders will be characterized as either “operating surplus” or “capital surplus.” We distribute available cash from operating surplus differently than available cash from capital surplus.

Definition of Operating Surplus. Operating surplus for any period generally means:

• our cash balance on the closing date of our initial public offering; plus

• $15.0 million (as described below); plus

• all of our cash receipts after the closing of our initial public offering, excluding cash from borrowings that are not working capital borrowings, sales of equity and debt securities and sales or other dispositions of assets outside the ordinary course of business; plus

• working capital borrowings made after the end of a quarter but before the date of determination of operating surplus for the quarter; less

• all of our operating expenditures after the closing of our initial public offering, including the repayment of working capital borrowings, but not the repayment of other borrowings, and including maintenance capital expenditures; less

• the amount of cash reserves established by our general partner in good faith to provide funds for future operating expenditures.

12

Definition of Capital Surplus. Generally, capital surplus will be generated only by:

• borrowings other than working capital borrowings;

• sales of debt and equity securities; and

• sales or other disposition of assets for cash, other than inventory, accounts receivable and other current assets sold in the ordinary course of business or as part of normal retirements or replacements of assets.

Characterization of Cash Distributions. We will treat all available cash distributed as coming from operating surplus until the sum of all available cash distributed since we began operations equals the operating surplus as of the most recent date of determination of available cash. We will treat any amount distributed in excess of operating surplus, regardless of its source, as capital surplus. As reflected above, operating surplus includes $15.0 million in addition to our cash balance on the closing date of our initial public offering, cash receipts from our operations and cash from working capital borrowings. This amount does not reflect actual cash on hand that is available for distribution to our unitholders. Rather, it is a provision that will enable us, if we choose, to distribute as operating surplus up to $15.0 million of cash we receive in the future from non-operating sources, such as asset sales, issuances of securities and long-term borrowings, that would otherwise be distributed as capital surplus. We do not anticipate that we will make any distributions from capital surplus.

Distributions of Available Cash from Operating Surplus

We will make distributions of available cash from operating surplus for any quarter in the following manner:

• First, to all unitholders and our general partner, in accordance with their percentage interests, until we distribute for each outstanding unit an amount equal to the minimum quarterly distribution for that quarter; and

• Thereafter, in the manner described in “—Incentive Distribution Rights” below.

However, no distributions of available cash from operating surplus shall be made in respect of any Class B Unit.

Incentive Distribution Rights

Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. Our general partner currently holds all of the incentive distribution rights, but may transfer these rights separately from its general partner interest, subject to restrictions in our partnership agreement.

If for any quarter we have distributed available cash from operating surplus to the unitholders in an amount equal to the minimum quarterly distribution, then we will distribute any additional available cash from operating surplus for that quarter among the unitholders and our general partner in the following manner:

• First, to all unitholders and our general partner, in accordance with their percentage interests, until each unitholder receives a total of $0.0833 per unit for that quarter (the “first target distribution”);

• Second, (i) to our general partner in accordance with its percentage interest, (ii) 13% to the holders of the incentive distribution rights, pro rata, and (iii) to all unitholders, pro rata, a percentage equal to 100% less the percentages applicable to our general partner and the holders of the incentive distribution rights, until each unitholder receives a total of $0.0958 per unit for that quarter (the “second target distribution”);

• Third, (i) to our general partner in accordance with its percentage interest, (ii) 35% to the holders of the incentive distribution rights, pro rata, and (iii) to all unitholders, pro rata, a percentage equal to 100%

13

less the percentages applicable to our general partner and the holders of the incentive distribution rights, until each unitholder receives a total of $0.2638 per unit for that quarter (the “third target distribution”); and

• Thereafter, (i) to our general partner in accordance with its percentage interest, (ii) 48% to the holders of the incentive distribution rights, pro rata, and (iii) to all unitholders, pro rata, a percentage equal to 100% less the percentages applicable to our general partner and the holders of the incentive distribution rights.

However, no distributions of available cash from operating surplus shall be made in respect of any Class B Unit.

Percentage Allocations of Available Cash from Operating Surplus

The following table illustrates the percentage allocations of the additional available cash from operating surplus between the unitholders and our general partner up to the various target distribution levels, assuming our general partner continues to hold all of our incentive distribution rights and its current approximately 1% general partner interest in us.

The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Target Amount,” until available cash from operating surplus we distribute reaches the next target distribution level, if any.

The percentage interests shown for the unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution.

	Total  Quarterly Distribution Target Amount	Marginal Percentage Interest  in Distributions
		Unitholders			General Partner
Minimum Quarterly Distribution	up to $0.075		99	%		1	%
	above $0.075
First Target Distribution	up to $0.0833		99	%		1	%
	above $0.0833
Second Target Distribution	up to $0.0958		86	%		14	%(1)
	above $0.0958
Third Target Distribution	up to $0.2638		64	%		36	%(1)
Thereafter	above $0.2638		51	%		49	%(1)

(1) Includes general partner interest.

Distributions from Capital Surplus

We will make distributions of available cash from capital surplus, if any, in the following manner:

• First, to all unitholders and our general partner, in accordance with their percentage interests, until a hypothetical holder of a common unit acquired in our initial public offering has received with respect to such common unit, during the period since our initial public offering through such date, distributions of available cash that are deemed to be capital surplus in an aggregate amount equal to the initial public offering price; and

• Thereafter, we will make all distributions of available cash from capital surplus as if they were from operating surplus.

14

However, no distributions of available cash from capital surplus shall be made in respect of any Class B Unit.

Our partnership agreement treats a distribution of capital surplus as the repayment of the initial unit price from the initial public offering, which is a return of capital. The initial public offering price less any distributions of capital surplus per unit is referred to as the “unrecovered initial unit price.” Each time a distribution of capital surplus is made, the minimum quarterly distribution and the target distribution levels will be reduced in the same proportion as the corresponding reduction in the unrecovered initial unit price. Because distributions of capital surplus will reduce the minimum quarterly distribution, after any of these distributions are made, it may be easier for our general partner to receive incentive distributions. However, any distribution of capital surplus before the unrecovered initial unit price is reduced to zero cannot be applied to the payment of the minimum quarterly distribution or any arrearages.

Once we distribute capital surplus on a unit in an amount equal to the initial unit price, we will reduce the minimum quarterly distribution and the target distribution levels to zero. We will then make all future distributions from operating surplus, with 48% to the holders of the incentive distribution rights and the remainder to all unitholders and our general partner in accordance with their percentage interests, pro rata.

Adjustment to the Minimum Quarterly Distribution and Target Distribution Levels

In addition to adjusting the minimum quarterly distribution and target distribution levels to reflect a distribution of capital surplus, if we combine our units into fewer units or subdivide our units into a greater number of units, we will proportionately adjust:

• the minimum quarterly distribution;

• target distribution levels; and

• the unrecovered initial unit price.

For example, if a two-for-one split of the common units should occur, the minimum quarterly distribution, the target distribution levels and the unrecovered initial unit price would each be reduced to 50% of its initial level. We will not make any adjustment by reason of the issuance of additional units for cash or property.

In addition, if legislation is enacted or if existing law is modified or interpreted in a manner that causes us to become taxable as a corporation or otherwise subject to taxation as an entity for federal, state or local income tax purposes, we will reduce the minimum quarterly distribution and the target distribution levels by multiplying the same by one minus the sum of the highest marginal federal corporate income tax rate that could apply and any increase in the effective overall state and local income tax rates. For example, if we became subject to a maximum marginal federal and effective state and local income tax rate of 38%, then the minimum quarterly distribution and the target distribution levels would each be reduced to 62% of their previous levels.

Distributions of Cash Upon Liquidation

General. If we dissolve in accordance with our partnership agreement, we will sell or otherwise dispose of our assets in a process called liquidation. We will first apply the proceeds of liquidation to the payment of our creditors. We will distribute any remaining proceeds to the unitholders and our general partner, in accordance with their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of our assets in liquidation.

Manner of Adjustments for Gain. The manner of the adjustment for gain is set forth in our partnership agreement. We generally allocate any gain to the partners in the following manner:

• First, to our general partner and the holders of units who have negative balances in their capital accounts to the extent of and in proportion to any such negative balances;

15

• Second, to the unitholders and our general partner, in accordance with their percentage interests, until the capital account for each common unit is equal to the sum of:

• the unrecovered initial unit price; and

• the amount of the minimum quarterly distribution for the quarter during which our liquidation occurs.

• Third, to the unitholders and our general partner, in accordance with their percentage interests, until we allocate under this paragraph an amount per unit equal to:

• the sum of the excess of the first target distribution per unit over the minimum quarterly distribution per unit for each quarter of our existence; less

• the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the minimum quarterly distribution per unit for each quarter of our existence that we distributed to the unitholders and to our general partner in accordance with their percentage interests;

• Fourth, 13% to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata, until we allocate under this paragraph an amount per unit equal to:

• the sum of the excess of the second target distribution per unit over the first target distribution per unit for each quarter of our existence; less

• the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the first target distribution per unit for each quarter of our existence that we distributed 13% to the holders of the incentive distribution rights, pro rata, and the remainder to our unitholders and to our general partner in accordance with their percentage interests, pro rata;

• Fifth, 35% to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata, until we allocate under this paragraph an amount per unit equal to:

• the sum of the excess of the third target distribution per unit over the second target distribution per unit for each quarter of our existence; less

• the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the second target distribution per unit for each quarter of our existence that we distributed 35% to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata; and

• Thereafter, 48% to the holders of the incentive distribution rights, pro rata, and the remainder to the unitholders and our general partner in accordance with their percentage interests, pro rata.

Adjustments to Capital Accounts upon the Issuance of Partnership Interests

We will make adjustments to capital accounts upon the issuance of additional partnership interests. In doing so, we will allocate any unrealized and, for tax purposes, unrecognized gain or loss resulting from the adjustments to the unitholders and our general partner in the same manner as we allocate gain or loss upon liquidation. In the event that we make positive adjustments to the capital accounts upon the issuance of additional partnership interests, we will allocate any later negative adjustments to the capital accounts resulting from the issuance of additional partnership interests or upon our liquidation in a manner that results, to the extent possible, in our general partner’s capital account balances equaling the amount that they would have been if no earlier positive adjustments to the capital accounts had been made.

Purpose

Under our partnership agreement, the purpose and nature of the business to be conducted by us is to:

(a) serve as a partner of Sunoco Logistics Partners Operations L.P., a Delaware limited partnership (the “Operating Partnership”), and, in connection therewith, to exercise all the rights and powers conferred upon us as a partner of the Operating Partnership pursuant to the Operating Partnership’s partnership agreement (the “Operating Partnership Agreement”) or otherwise;

(b) engage directly in, or enter into or form any corporation, partnership, joint venture, limited liability company or other arrangement to engage indirectly in, any business activity that the Operating Partnership is permitted to engage in by the Operating Partnership Agreement or that its subsidiaries are permitted to engage in by their limited liability company or partnership agreements and, in connection therewith, to exercise all of the rights and powers conferred upon us pursuant to the agreements relating to such business activity;

(c) engage directly in, or enter into or form any corporation, partnership, joint venture, limited liability company or other arrangement to engage indirectly in, any business activity that is approved by our general partner and which lawfully may be conducted by a limited partnership organized pursuant to the Delaware Revised Uniform Limited Partnership Act (the “Delaware Act”) and, in connection therewith, to exercise all of the rights and powers conferred upon us pursuant to the agreements relating to such business activity; provided, however, that our general partner determines, as of the date of the acquisition or commencement of such activity, that such activity (i) generates “qualifying income” (as such term is defined pursuant to Section 7704 of the

17

Internal Revenue Code of 1986, as amended (the “Code”)) or a subsidiary or our activity that generates qualifying income or (ii) enhances the operations of an activity of the Operating Partnership; and

(d) do anything necessary or appropriate to the foregoing, including the making of capital contributions or loans to a member of the partnership group.

Our general partner has no duty or obligation to propose or approve, and may decline to propose or approve, the conduct by us of any business free of any fiduciary duty or obligation whatsoever to us, any limited partner or assignee and, in declining to so propose or approve, is not required to act in good faith or pursuant to any other standard imposed by our partnership agreement, any governing agreement of a member of the partnership group, any other agreement contemplated by our partnership agreement or under the Delaware Act or any other law, rule or regulation.

Board of Directors

Our general partner manages our operations and activities on our behalf through its directors and officers. Our general partner is not elected by our common unitholders and will not be subject to re-election in the future. Common unitholders will not be entitled to elect the directors of our general partner on an annual or other continuing basis. The board of directors of our general partner is chosen by ETP and ETE Common Holdings, LLC, a Delaware limited liability company (“ETE Common Holdings”), its sole members, and only ETP and ETE Common Holdings have the right to remove directors.

Power of Attorney

Each limited partner, and each person who acquires a common unit from a unitholder and executes and delivers a transfer application, grants to our general partner and, if appointed, a liquidator, a power of attorney to, among other things, execute and file documents required for our qualification, continuance or dissolution. The power of attorney also grants our general partner the authority to amend, and to make consents and waivers under, our partnership agreement.

Capital Contributions

Except as described below under “—Limited Liability,” the common units will be fully paid, and common unitholders will not be required to make additional capital contributions to us.

Limited Liability

Assuming that a limited partner does not participate in the control of our business within the meaning of the Delaware Act and that it otherwise acts in conformity with the provisions of our partnership agreement, the limited partner’s liability under the Delaware Act will be limited, subject to possible exceptions, to the amount of capital such limited partner is obligated to contribute to us for its common units plus such limited partner’s share of any undistributed profits and assets and any funds wrongfully distributed to it as described below. If it were determined, however, that the right, or exercise of the right, by our limited partners as a group:

• to remove or replace our general partner;

• to approve certain amendments to our partnership agreement; or

• to take any other action under our partnership agreement;

constituted “participation in the control” of our business for the purposes of the Delaware Act, then the limited partners could be held personally liable for our obligations under the laws of Delaware, to the same extent as our general partner. This liability would extend to persons who transact business with us who reasonably believe that

18

a limited partner is a general partner based on such limited partner’s conduct. Neither our partnership agreement nor the Delaware Act specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner. While this does not mean that a limited partner could not seek legal recourse, we know of no precedent for this type of a claim in Delaware case law.

Under the Delaware Act, a limited partnership may not make a distribution to a partner if, after the distribution, all liabilities of the limited partnership, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of the limited partnership, would exceed the fair value of the assets of the limited partnership. For the purpose of determining the fair value of the assets of a limited partnership, the Delaware Act provides that the fair value of property subject to liability for which recourse of creditors is limited will be included in the assets of the limited partnership only to the extent that the fair value of that property exceeds the nonrecourse liability. The Delaware Act provides that a limited partner who receives a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Act will be liable to the limited partnership for the amount of the distribution; provided, however, that such limited partner will have no liability for the amount of the distribution after the expiration of three years from the date of the distribution. Under the Delaware Act, an assignee who becomes a substituted limited partner of a limited partnership is liable for the obligations of its assignor to make contributions to the limited partnership, excluding any obligations of the assignor with respect to wrongful distributions, as described above, except the assignee is not obligated for liabilities unknown to it at the time it became a limited partner and that could not be ascertained from the partnership agreement.

Our subsidiaries conduct business in multiple states. Maintenance of our limited liability as a limited partner or member of our subsidiaries formed as limited partnerships or limited liability companies, respectively, may require compliance with legal requirements in the jurisdictions in which such subsidiaries conduct business, including qualifying our subsidiaries to do business there. Limitations on the liability of a limited partner or member for the obligations of a limited partnership or limited liability company, respectively, have not been clearly established in many jurisdictions. If it were determined that we were, by virtue of our limited partner interest or limited liability company interest in our subsidiaries or otherwise, conducting business in any state without compliance with the applicable limited partnership or limited liability company statute, or that the right or exercise of the right by our limited partners as a group to remove or replace our general partner, to approve certain amendments to our partnership agreement or to take other action under our partnership agreement constituted “participation in the control” of our business for purposes of the statutes of any relevant jurisdiction, then our limited partners could be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We will operate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of the limited partners.

Issuance of Additional Partnership Securities; Preemptive Rights

Our partnership agreement authorizes us to issue an unlimited number of additional partnership securities and options, rights, warrants and appreciation rights relating to the partnership securities for any partnership purpose at any time and from time to time to such persons, for such consideration and on such terms and conditions as our general partner determines, all without the approval of any limited partners.

It is possible that we will fund acquisitions through the issuance of additional common units or other equity securities. Holders of any additional common units we issue will be entitled to share equally with the then-existing holders of common units in our distributions of available cash. In addition, the issuance of additional partnership interests may dilute (i) the percentage interests of the then-existing holders of common units in our net assets and (ii) the voting rights of the then-existing holders of common units under our partnership agreement.

In accordance with Delaware law and the provisions of our partnership agreement, we may also issue additional partnership securities that have special voting rights to which the common units are not entitled.

19

Upon issuance of additional partnership securities, our general partner will have the right to make additional capital contributions to the extent necessary to maintain its then-current general partner interest in us; provided, however, that the capital contributions of our general partner will be offset to the extent contributions received by us in exchange for the issuance of additional partnership securities are used by us concurrently with such contributions to redeem or repurchase from any person outstanding partnership securities of the same class as the partnership securities that were issued. Moreover, our general partner will have the right, which it may from time to time assign in whole or in part to any of its affiliates, to purchase common units or other partnership securities whenever, and on the same terms that, we issue those securities to persons other than our general partner and its affiliates, to the extent necessary to maintain its percentage interest, including its interest represented by common units, that existed immediately prior to each issuance.

The holders of our common units do not have preemptive rights to acquire additional common units or other partnership securities.

Amendment of the Partnership Agreement

General

Amendments to our partnership agreement may be proposed only by our general partner. Our general partner has no duty or obligation to propose any amendment to our partnership agreement and may decline to do so free of any fiduciary duty or obligation whatsoever to us, any limited partner or assignee and, in declining to propose an amendment, is not required to act in good faith or pursuant to any other standard imposed by our partnership agreement, any governing agreement of a member of the partnership group, any other agreement contemplated under our partnership agreement or under the Delaware Act or any other law, rule or regulation. A proposed amendment will be effective upon its approval by the holders of a majority of the outstanding common units (a “unit majority”), unless a greater or different percentage is required under our partnership agreement or by Delaware law. Each proposed amendment that requires the approval of the holders of a specified percentage of outstanding units will be set forth in a writing that contains the text of the proposed amendment. If such an amendment is proposed, our general partner will seek the written approval of the requisite percentage of outstanding units or call a meeting of the unitholders to consider and vote on such proposed amendment. Our general partner will notify all record holders upon final adoption of any such proposed amendments.

Restrictions on Certain Amendments

Our partnership agreement provides that:

(1) no provision of our partnership agreement that establishes a percentage of outstanding units (including units deemed owned by our general partner) required to take any action shall be amended, altered, changed, repealed or rescinded in any respect that would have the effect of reducing such voting percentage unless such amendment is approved by the written consent or the affirmative vote of holders of outstanding units whose aggregate outstanding units constitute not less than the voting requirement sought to be reduced;

(2) no amendment to our partnership agreement may (a) enlarge the obligations of any limited partner without its consent, unless such shall be deemed to have occurred as a result of an amendment approved pursuant to clause (3) below, (b) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable to, our general partner or any of its affiliates without its consent, which consent may be given or withheld at its option, (c) change the provision of our partnership agreement providing for our dissolution upon an election to dissolve our partnership by our general partner that is approved by a unit majority (the “election to dissolve provision”), or (d) change the term of our partnership or, except as set forth in the election to dissolve provision, give any person the right to dissolve our partnership;

(3) except for mergers or consolidations approved pursuant to the partnership agreement, and without limitation of our general partner’s authority to adopt amendments to our partnership agreement described below

20

under “—No Unitholder Approval,” any amendment that would have a material adverse effect on the rights or preferences of any class of partnership interests in relation to other classes of partnership interests must be approved by the holders of not less than a majority of the outstanding partnership interests of the class affected;

(4) except for amendments described below under “—No Unitholder Approval” and except in connection with unitholder approval of a merger or consolidation, no amendments shall become effective without the approval of the holders of at least 90% of the outstanding units voting as a single class unless we obtain an opinion of counsel to the effect that such amendment will not affect the limited liability of any limited partner under applicable law; and

(5) except for amendments described below under “—No Unitholder Approval,” the provisions set forth in clauses (1) through (4) above may only be amended with the approval of the holders of at least 90% of the outstanding units.

No Unitholder Approval

Our general partner, without the approval of any limited partner, may amend any provision of our partnership agreement to reflect:

(1) a change in our name, the location of our principal place of business, our registered agent or our registered office;

(2) admission, substitution, withdrawal or removal of partners in accordance with our partnership agreement;

(3) a change that our general partner determines to be necessary or appropriate to qualify or continue the qualification of our partnership as a limited partnership or a partnership in which the limited partners have limited liability under the laws of any state or to ensure that the members of the partnership group will not be treated as associations taxable as corporations or otherwise taxed as entities for federal income tax purposes;

(4) a change that our general partner determines (a) does not adversely affect the limited partners (including any particular class of partnership interests as compared to other classes of partnership interests) in any material respect, (b) to be necessary or appropriate to (i) satisfy any requirements, conditions or guidelines contained in any opinion, directive, order, ruling or regulation of any federal or state agency or judicial authority or contained in any federal or state statute (including the Delaware Act) or (ii) facilitate the trading of our units (including the division of any class or classes of outstanding units into different classes to facilitate uniformity of tax consequences within such classes of units) or comply with any rule, regulation, guideline or requirement of any national securities exchange on which the units are or will be listed for trading, (c) to be necessary or appropriate in connection with action taken by our general partner pursuant to the provisions of our partnership agreement governing distributions, subdivisions and combinations of partnership securities or (d) is required to effect the intent of the provisions of our partnership agreement or is otherwise contemplated by our partnership agreement;

(5) a change in our fiscal year or taxable year and any other changes that our general partner determines to be necessary or appropriate as a result of a change in our fiscal year or taxable year, including, if our general partner shall so determine, a change in the definition of “Quarter” under our partnership agreement and the dates on which distributions are to be made by us;

(6) an amendment that is necessary, in the opinion of counsel, to prevent us, or our general partner or its directors, officers, trustees or agents from in any manner being subjected to the provisions of the Investment Company Act of 1940, as amended, the Investment Advisers Act of 1940, as amended, or “plan asset” regulations adopted under the Employee Retirement Income Security Act of 1974, as amended, regardless of whether such are substantially similar to plan asset regulations currently applied or proposed by the United States Department of Labor;

21

(7) subject to certain limitations, an amendment that our general partner determines to be necessary or appropriate in connection with the authorization of issuance of any class or series of partnership securities pursuant to our partnership agreement;

(8) any amendment expressly permitted in our partnership agreement to be made by our general partner acting alone;

(9) an amendment effected, necessitated or contemplated by a merger agreement approved in accordance with the provisions of our partnership agreement;

(10) an amendment that our general partner determines to be necessary or appropriate to reflect and account for the formation by us of, or investment by us in, any corporation, partnership, joint venture, limited liability company or other entity, in connection with the conduct by us of activities permitted by the terms of our partnership agreement;

(11) a merger or conveyance pursuant to which (a) our general partner has received an opinion of counsel that the conversion, merger or conveyance, as the case may be, would not result in the loss of the limited liability of any limited partner or any member of the partnership group or cause us or any member of the partnership group 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 previously treated as such), (b) the sole purpose of such conversion, merger or conveyance is to effect a mere change in the legal form of us into another limited liability entity and (c) the governing instruments of the new entity provide the limited partners and our general partner with the same rights and obligations as are contained in our partnership agreement; or

(12) any other amendments substantially similar to the foregoing.

Action Relating to the Operating Partnership Agreement

Without the approval of holders of a unit majority, our general partner may not, on our behalf as a limited partner of the Operating Partnership, consent to any amendment to the Operating Partnership Agreement or, except as expressly permitted by our partnership agreement, take any action permitted to be taken by a partner of the Operating Partnership, in either case, that would adversely affect our limited partners (including any particular class of partnership interests as compared to any other class of partnership interests) in any material respect.

Merger, Sale or Other Disposition of Assets

Our partnership agreement generally prohibits our general partner, without the prior approval of a unit majority, from causing us to, among other things, sell, exchange or otherwise dispose of all or substantially all of our assets in a single transaction or a series of related transactions, including by way of merger, consolidation or other combination, or approving on our behalf the sale, exchange or other disposition of all or substantially all of the assets of the Operating Partnership. The general partner may, however, mortgage, pledge, hypothecate or grant a security interest in all or substantially all of our assets or the Operating Partnership’s assets without the approval of a unit majority. The general partner may also sell all or substantially all of our assets or the Operating Partnership’s assets under a foreclosure or other realization upon those encumbrances without the approval of a unit majority.

If certain conditions specified in our partnership agreement are satisfied and without the prior approval of our limited partners, our general partner may convert us or any of our subsidiaries into a limited liability entity, merge us or any of our subsidiaries into, or convey some or all of our assets to, a newly formed entity if the sole purpose of that merger or conveyance is to change our legal form into another limited liability entity.

22

Our unitholders are not entitled to dissenters’ rights of appraisal under the partnership agreement or applicable Delaware law in the event of a merger or consolidation, a sale of substantially all of our assets, or any other transaction or event.

Reimbursement of Our General Partner

Our general partner is not compensated for its services as a general partner or managing member of any member of the partnership group. Our general partner is reimbursed on a monthly basis, or such other basis as our general partner may determine, for (i) all direct and indirect expenses it incurs or payments it makes on our behalf (including salary, bonus, incentive compensation and other amounts paid to any person including affiliates of our general partner to perform services for us or for our general partner in the discharge of its duties to us), and (ii) all other expenses allocable to us or otherwise incurred by our general partner in connection with operating our business (including expenses allocated to our general partner by its affiliates). Our general partner determines the expenses that are allocable to us.

Withdrawal or Removal of Our General Partner

Our general partner may withdraw as general partner without first obtaining approval of any unitholder by giving 90 days’ notice to our unitholders, and that withdrawal will not constitute a breach of our partnership agreement. In addition, our partnership agreement permits our general partner in some instances to sell or otherwise transfer all of its general partner interest in us without the approval of the unitholders.

If our general partner gives a notice of withdrawal, the holders of a unit majority, may, prior to the effective date of such withdrawal, elect a successor general partner. The person so elected as successor general partner will automatically become the successor general partner or managing member, to the extent applicable, of the other members of the partnership group of which our general partner is a general partner or a managing member. If, prior to the effective date of our general partner’s withdrawal, a successor is not selected by our unitholders or we do not receive a withdrawal opinion of counsel regarding limited liability and tax matters, our partnership will be dissolved in accordance with our partnership agreement.

Our general partner may be removed if such removal is approved by our unitholders holding at least 66 ²/₃% of the outstanding units (including units held by our general partner and its affiliates). The right of the holders of outstanding units to remove our general partner may not be exercised unless we have received a withdrawal opinion of counsel regarding limited liability and tax matters. The ownership of more than 33 ¹/₃% of our outstanding units by our general partner and its affiliates would give it the practical ability to prevent its removal.

We will be required to reimburse the departing general partner for all amounts due the departing general partner, including, without limitation, all employee-related liabilities, including severance liabilities, incurred in connection with the termination of any employees employed by the departing general partner or its affiliates for the benefit of us or the other members of the partnership group.

Dissolution and Liquidation

We will continue as a limited partnership until dissolved under our partnership agreement. We will dissolve upon:

(1) the withdrawal, removal, bankruptcy or dissolution of our general partner, unless a successor general partner is elected prior to or on the effective date of such withdrawal, removal, bankruptcy or dissolution and a withdrawal opinion of counsel is received by us;

(2) an election to dissolve us by our general partner that is approved by the holders of a unit majority;

(3) the entry of a decree of judicial dissolution of us pursuant to the provisions of the Delaware Act; or

23

(4) the sale, exchange or other disposition of all or substantially all of the assets and properties of the partnership group.

Upon (a) our dissolution following the withdrawal or removal of our general partner and the failure of the partners to select a successor general partner, then within 90 days thereafter, or (b) our dissolution upon the bankruptcy or dissolution of our general partner, then, to the maximum extent permitted by law, within 180 days thereafter, the holders of a unit majority may elect to reconstitute us and continue our business on the same terms and conditions set forth in our partnership agreement by forming a new limited partnership on terms identical to those set forth in our partnership agreement and having as the successor general partner a person approved by the holders of a unit majority. Unless such an election is made within the applicable time period as set forth above, we shall conduct only activities necessary to wind up our affairs.

Transfer of the General Partner’s General Partner Interest

Our general partner may transfer all or any of its general partner interest without unitholder approval. As a condition to such transfer, (i) the transferee must agree to assume the rights and duties of the general partner under our partnership agreement and to be bound by the provisions of our partnership agreement, (ii) we must receive an opinion of counsel that such transfer would not result in the loss of limited liability of any limited partner or of any limited partner of the Operating Partnership or cause us or the Operating Partnership 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 already so treated or taxed) and (iii) such transferee must also agree to purchase all (or the appropriate portion thereof, if applicable) of the partnership or membership interest of our general partner as the general partner or managing member, if any, of each other member of the partnership group.

Transfer of Ownership Interests in Our General Partner

At any time, the members of our general partner may sell or transfer all or part of their membership interests in our general partner to an affiliate or a third party without the approval of our unitholders.

Transfer of Incentive Distribution Rights

Our general partner or any other holder of our incentive distribution rights may transfer any or all of its incentive distribution rights without unitholder approval. As a condition to such transfer, the transferee must agree to be bound by the provisions of our partnership agreement.

Change of Management Provisions

Our partnership agreement contains specific provisions that are intended to discourage a person or group from attempting to remove Sunoco Partners LLC as our general partner or otherwise change management. If at any time any person or group (other than our general partner or its affiliates) beneficially owns 20% or more of any outstanding partnership securities of any class then outstanding, all partnership securities owned by such person or group shall not be voted on any matter and shall not be considered to be outstanding when sending notices of a meeting of limited partners to vote on any matter (unless otherwise required by law), calculating required votes, determining the presence of a quorum or for other similar purposes under our partnership agreement. The foregoing limitation does not apply (i) to any person or group who acquired 20% or more of any outstanding partnership securities of any class then outstanding directly from our general partner or its affiliates, (ii) to any person or group who acquired 20% or more of any outstanding partnership securities of any class then outstanding directly or indirectly from a person or group described in clause (i) provided that our general partner has notified such person or group in writing that such limitation will not apply, or (iii) to any person or group who acquired 20% or more of any partnership securities issued by us with the prior approval of the board of directors of our general partner.

24

Limited Call Right

If at any time our general partner and its affiliates hold more than 80% of the total limited partner interests of any class then outstanding, our general partner will then have the right, which right it may assign and transfer in whole or in part to us or any affiliate of our general partner, exercisable at its option, to purchase all, but not less than all, of such limited partner interests of such class then outstanding held by persons other than our general partner and its affiliates, at the greater of:

(1) the current market price as of the date three days prior to the date that notice of the election to purchase is mailed; and

(2) the highest price paid by our general partner or any of its affiliates for any such limited partner interest of such class purchased during the 90-day period preceding the date that notice of the election to purchase is mailed.

Meetings; Voting

Except as described above under “—Change of Management Provisions,” unitholders or assignees who are record holders of units on the record date will be entitled to notice of, and to vote at, meetings of our limited partners and to act upon matters for which approvals may be solicited. Units that are owned by an assignee who is a record holder, but who has not yet been admitted as a limited partner, will be voted by the general partner at the written direction of the record holder.

Absent direction of this kind, the units will not be voted, except that, in the case of units held by our general partner on behalf of non-citizen assignees, our general partner will distribute the votes on those common units in the same ratios as the votes of limited partners on other units are cast.

Any action that is required or permitted to be taken by the unitholders may be taken either at a meeting of the unitholders or without a meeting if consents in writing describing the action so taken are signed by holders of the number of units necessary to authorize or take that action at a meeting.

Meetings of the unitholders may be called by the general partner or by unitholders owning at least 20% of the outstanding units of the class for which a meeting is proposed. Unitholders may vote either in person or by proxy at meetings. The holders of a majority of the outstanding units of the class or classes for which a meeting has been called, represented in person or by proxy, will constitute a quorum unless any action by the unitholders requires approval by holders of a greater percentage of the units, in which case the quorum will be the greater percentage.

Each record holder of a unit has a vote according to its percentage interest in us, although additional limited partner interests having special voting rights could be issued. Please read “—Issuance of Additional Partnership Securities; Preemptive Rights” above. However, if at any time any person or group, other than the general partner and its affiliates, or a direct or subsequently approved transferee of the general partner or its affiliates, acquires, in the aggregate, beneficial ownership of 20% or more of any class of units then outstanding, that person or group will lose voting rights on all of its units and the units may not be voted on any matter and will not be considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes, determining the presence of a quorum or for other similar purposes. Please read “—Change of Management Provisions” above. Units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instructions of the beneficial owner unless the arrangement between the beneficial owner and its nominee provides otherwise.

Any notice, demand, request, report or proxy material required or permitted to be given or made to record holders of units under our partnership agreement will be delivered to the record holder by us or by the transfer agent.

25

Holders of common units have very limited voting rights and may vote on the following matters:

• a sale or exchange of all or substantially all of our assets;

• the election of a successor general partner in connection with the withdrawal or removal of our general partner;

• dissolution or reconstitution of our partnership;

• a merger of our partnership;

• issuance of limited partner interests in some circumstances; and

• some amendments to the partnership agreement, including any amendment that would cause us to be treated as an association taxable as a corporation.

Removal of our general partner requires:

• a 66 ²/₃% vote of all outstanding units; and

• the election of a successor general partner by the holders of a unit majority.

Status as Limited Partner or Assignee

An assignee of a common unit, after executing and delivering a transfer application, but pending its admission as a substituted limited partner, is entitled to an interest equivalent to that of a limited partner for the right to share in allocations and distributions from us, including liquidating distributions. Our general partner will vote and exercise other powers attributable to any of our common units owned by an assignee that has not become a substituted limited partner at the written direction of the assignee. Please read “—Meetings; Voting.” Transferees that do not execute and deliver a transfer application will not be treated as assignees or as record holders of our common units and will not receive cash distributions, federal income tax allocations or reports furnished to holders of our common units. Please read “Description of the Common Units—Transfer of Common Units.”

Non-Citizen Assignees; Redemption

If we are or become subject to federal, state or local laws or regulations that, in the reasonable determination of our general partner, create a substantial risk of cancellation or forfeiture of any property that we have an interest in because of the nationality, citizenship or other related status of any limited partner or assignee, we may redeem the units held by the limited partner or assignee at their current market price. In order to avoid any cancellation or forfeiture, our general partner may require each limited partner or assignee to furnish information about its nationality, citizenship or related status. If a limited partner or assignee fails to furnish information about its nationality, citizenship or other related status within 30 days after a request for the information or our general partner determines after receipt of the information that the limited partner or assignee is not an eligible citizen, the limited partner or assignee may be treated as a non-citizen assignee. In addition to other limitations on the rights of an assignee that is not a substituted limited partner, a non-citizen assignee does not have the right to direct the voting of its units and may not receive distributions in kind upon our liquidation.

Books and Reports

Our general partner is required to keep appropriate books and records with respect to our business at our principal offices. Our books are maintained, for both federal income tax and financial reporting purposes, on an accrual basis. For both federal income tax and financial reporting purposes, our fiscal year end is December 31.

We will furnish or make available to record holders of common units, no later than 120 days after the close of each fiscal year, an annual report containing audited financial statements and a report on those financial

26

statements by our independent registered public accounting firm. Except for the fourth quarter of each fiscal year, we will also furnish or make available unaudited financial statements no later than 90 days after the close of each quarter.

We will furnish each record holder with information reasonably required for tax reporting purposes within 90 days after the close of each calendar year.

Right to Inspect Our Books and Records

Except as described below, each limited partner has the right, for a purpose reasonably related to such limited partner’s interest as a limited partner in our partnership, upon reasonable written demand and at such limited partner’s own expense:

• to obtain true and full information regarding the status of our business and financial condition;

• promptly after becoming available, to obtain a copy of our federal, state and local income tax returns for each year;

• to have furnished to it a current list of the name and last known business, residence or mailing address of each partner;

• to have furnished to it a copy of our partnership agreement and our certificate of limited partnership and all amendments thereto, together with copies of all powers of attorney pursuant to which our partnership agreement, our certificate of limited partnership and all amendments thereto have been executed;

• to obtain true and full information regarding the amount of cash and a description and statement of the net agreed value of any other capital contribution by each partner and that each partner has agreed to contribute in the future, and the date on which each became a partner; and

• to obtain such other information regarding our affairs as is just and reasonable.

The general partner may, and intends to, keep confidential from the limited partners trade secrets or other information the disclosure of which the general partner believes in good faith is not in our best interests, could damage the partnership group or that we are required by law or by agreements with third parties to keep confidential.

Registration Rights

Under the partnership agreement, we have agreed to register for resale under the Securities Act and applicable state securities laws any common units or other partnership securities proposed to be sold by our general partner or any of its affiliates or their assignees if an exemption from the registration requirements is not otherwise available. These registration rights continue for two years following any withdrawal or removal of Sunoco Partners LLC as our general partner. We are obligated to pay all expenses incidental to such registration, excluding underwriting discounts and commissions.

Indemnification

Section 17-108 of the Delaware Act empowers a Delaware limited partnership to indemnify and hold harmless any partner or other person from and against all claims and demands whatsoever. Under our partnership agreement, in most circumstances, we will indemnify the following persons (each an “indemnitee”) to the fullest extent permitted by law, from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any indemnitee may be involved, or is threatened to be involved, as a party or otherwise, by reason of its status as an indemnitee:

• our general partner;

27

• any departing general partner;

• any person who is or was an affiliate of our general partner or any departing general partner;

• any person who is or was a member, partner, officer, director, fiduciary or trustee of any member of the partnership group, our general partner or any departing partner or any affiliate of any member of the partnership group, our general partner or any departing partner;

• any person who is or was serving at the request of our general partner or any departing partner or any affiliate of our general partner or any departing partner as an officer, director, member, partner, fiduciary or trustee of another person (provided, that a person will not be an indemnitee by reason of providing, on a fee-for-services basis, trustee, fiduciary or custodial services); or

• any person that our general partner designates as an “indemnitee” for purposes of our partnership agreement.

Any indemnification under these provisions will only be out of our assets. Unless it otherwise agrees in its sole discretion, our general partner will not be personally liable for, or have any obligation to contribute or loan funds or assets to us to enable us to effectuate, such indemnification. We may purchase insurance against liabilities asserted against and expenses incurred by persons for our activities, regardless of whether we would have the power to indemnify the person against liabilities under the partnership agreement.

Under our partnership agreement, an indemnitee will not be indemnified and held harmless if there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that, in respect of the matter for which the indemnitee is seeking indemnification pursuant to our partnership agreement, the indemnitee acted in bad faith or engaged in fraud, willful misconduct or gross negligence or, in the case of a criminal matter, acted with knowledge that the indemnitee’s conduct was unlawful.

In the opinion of the SEC, indemnification provisions that purport to include indemnification for liabilities arising under the Securities Act are contrary to public policy and are, therefore, unenforceable.

CONFLICTS OF INTEREST AND FIDUCIARY RESPONSIBILITIES

Conflicts of Interest

Conflicts of interest exist and may arise in the future as a result of the relationships between our general partner and its affiliates, including ETP and ETE Common Holdings, on the one hand, and our partnership and our limited partners, on the other hand. The directors and officers of our general partner have fiduciary duties to manage our general partner in a manner beneficial to ETP. At the same time, our general partner has a fiduciary duty to manage our partnership in a manner beneficial to us and our unitholders.

Whenever a conflict arises between our general partner or its affiliates, on the one hand, and us or any other partner, on the other hand, our general partner will resolve that conflict. Our partnership agreement contains provisions that modify and limit our general partner’s fiduciary duties to the unitholders. Our partnership agreement also restricts the remedies available to unitholders for actions taken that, without those limitations, might constitute breaches of fiduciary duty.

Our general partner will not be in breach of its obligations under our partnership agreement or its duties to us or our unitholders if the resolution of the conflict is:

• approved by the conflicts committee of the board of directors of our general partner, although our general partner is not obligated to seek such approval;

• approved by the vote of a majority of the outstanding common units, excluding any common units owned by our general partner or any of its affiliates;

• on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or

• fair and reasonable to us, taking into account the totality of the relationships among the parties involved, including other transactions that may be particularly favorable or advantageous to us.

As indicated above, our general partner may, but is not required to, seek the approval of such resolution from the conflicts committee of its board of directors. If our general partner does not seek approval from the conflicts committee and its board of directors determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in the third or fourth bullet points above, then it will be presumed that, in making its decision, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. Unless the resolution of a conflict is specifically provided for in our partnership agreement, our general partner or the conflicts committee may consider any factors it determines in good faith to consider when resolving a conflict. When our partnership agreement requires someone to act in good faith, it requires that person to reasonably believe that he is acting in the best interests of the partnership, unless the context otherwise requires.

Conflicts of interest could arise in the situations described below, among others.

Actions taken by our general partner may affect the amount of cash available for distribution to unitholders or to our general partner in respect of the incentive distribution rights.

The amount of cash that is available for distribution to unitholders is affected by decisions of our general partner regarding such matters as:

• amount and timing of asset purchases and sales;

• cash expenditures;

• borrowings;

29

• the issuance of additional units; and

• the creation, reduction or increase of cash reserves in any quarter.

In addition, borrowings by us and our affiliates do not constitute a breach of any duty owed by our general partner to our unitholders, including borrowings that have the purpose or effect of enabling our general partner to receive distributions on the incentive distribution rights.

For example, in the event we have not generated sufficient cash from our operations to pay the minimum quarterly distribution on our common units, our partnership agreement permits us to borrow funds, which may enable us to make this distribution on all outstanding units. Please read “Cash Distributions” in this prospectus.

Our partnership agreement provides that we and our subsidiaries may borrow funds from our general partner and its affiliates. Our general partner and its affiliates may not borrow funds from us, the Operating Partnership or its operating subsidiaries, other than as provided in the treasury services agreement between us and an affiliate of ETP, which is the controlling owner of our general partner.

We do not have any officers or employees and rely solely on officers and employees of our general partner and its affiliates.

Affiliates of our general partner conduct businesses and activities of their own in which we have no economic interest. If these separate activities are significantly greater than our activities, there could be material competition for the time and effort of certain of the officers and employees who provide services to our general partner. Generally, the officers of our general partner spend substantially all of their time managing our business and affairs. However, certain of our general partner’s officers currently devote time to the affairs of affiliates of ETP, which is the controlling owner of our general partner, and such officers are compensated by such ETP affiliates for the services rendered to them.

We will reimburse our general partner and its affiliates for expenses.

We will reimburse our general partner and its affiliates for costs incurred in managing and operating us, including costs incurred in rendering staff and support services to us. Our partnership agreement provides that our general partner will determine the expenses that are allocable to us in good faith.

Our general partner intends to limit its liability regarding our obligations.

Our general partner intends to limit its liability under contractual arrangements so that the other party has recourse only to our assets, and not against our general partner or its assets. Our partnership agreement provides that any action taken by our general partner to limit its liability or our liability is not a breach of our general partner’s fiduciary duties, even if we could have obtained more favorable terms without the limitation on liability.

Common unitholders will have no right to enforce obligations of our general partner and its affiliates under agreements with us.

Any agreements between us, on the one hand, and our general partner and its affiliates, on the other, will not grant to the unitholders, separate and apart from us, the right to enforce the obligations of our general partner and its affiliates in our favor.

Contracts between us, on the one hand, and our general partner and its affiliates, on the other, may not be the result of arm’s-length negotiations.

Our partnership agreement allows our general partner to determine, in good faith, any amounts to pay itself or its affiliates for any services rendered to us. Our general partner may also enter into additional contractual

30

arrangements with any of its affiliates on our behalf. Neither our partnership agreement nor any of the other agreements, contracts and arrangements between us, on the one hand, and our general partner and its affiliates, on the other, are required to be the result of arm’s-length negotiations. Our general partner will determine, in good faith, the terms of any of these transactions.

Our general partner and its affiliates will have no obligation to permit us to use any facilities or assets of our general partner and its affiliates, except as may be provided in contracts entered into specifically dealing with that use. There will not be any obligation of our general partner and its affiliates to enter into any contracts of this kind.

Common units are subject to our general partner’s limited call right.

If, at any time, our general partner and its affiliates own more than 80% of our common units then outstanding, our general partner has the right, but not the obligation, which it may assign to any of its affiliates or to us, to acquire all, but not less than all, of the remaining common units at a price not less than the then-current market price of the common units. Our general partner may exercise this right at its option, free of any fiduciary duty or obligation to us or our unitholders. As a result, a unitholder may have its common units purchased from it at an undesirable time or price. For a description of this right, please read “Description of Our Partnership Agreement—Limited Call Right.”

We may choose not to retain separate counsel for ourselves or for the holders of common units.

Attorneys, independent registered public accountants and others who will perform services for us in the future will be selected by our general partner or the conflicts committee and may also perform services for our general partner and its affiliates. We may, but are not required to, retain separate counsel for ourselves or the holders of common units in the event of a conflict of interest arising between our general partner and its affiliates, on the one hand, and us or the holders of common units, on the other, depending on the nature of the conflict. Such conflicts may arise out of extraordinary transactions between us and ETP or its affiliates, such as transfers of material assets or mergers or material amendments to our agreements with ETP and its affiliates. We do not intend to retain separate counsel in most cases.

Our general partner’s affiliates may compete with us.

Our partnership agreement provides that the general partner will be restricted from engaging in any business activities other than those incidental to its ownership of interests in us and certain services the employees of our general partner provide to ETP and its affiliates. Except as provided in our partnership agreement and in our omnibus agreement with affiliates of ETP, neither ETP nor its affiliates, other than our general partner, are prohibited from engaging in other businesses or activities, including those that might be in direct competition with us.

Conflicts of interest may arise between us and ETP, as the controlling owner of our general partner which, due to limited fiduciary responsibilities, may permit ETP and its affiliates to favor their own interests to the detriment of our unitholders.

ETP is the controlling owner of our current approximately 1% general partner interest and owns 25% of our limited partnership interests. Conflicts of interest may arise, from time to time, between ETP and its affiliates (including our general partner), on the one hand, and us and our unitholders, on the other hand. As a result of these conflicts, our general partner may favor its own interests and the interests of its affiliates (including ETP) over the interests of our unitholders. These conflicts may include, among others, the following situations:

• ETP and its affiliates may engage in competition with us. Neither our partnership agreement nor any other agreement requires ETP to pursue a business strategy that favors us or utilizes our assets, and our general partner may consider the interests of parties other than us, such as ETP, in resolving conflicts of interest;

31

• under our partnership agreement, our general partner’s fiduciary duties are restricted, and our unitholders have only limited remedies available in the event of conduct constituting a potential breach of fiduciary duty by our general partner;

• our general partner determines the amount and timing of asset purchases and sales, capital expenditures, borrowings, issuance of additional partnership securities, and reserves, each of which can affect the amount of cash available for distribution to our unitholders and the amount received by our general partner in respect of its incentive distribution rights;

• our general partner determines which costs incurred by ETP and its affiliates are reimbursable by us; and

• our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for services rendered, or from entering into additional contractual arrangements with any of these entities on our behalf, so long as the terms of any additional contractual arrangements are fair and reasonable to us; and our general partner controls the enforcement of obligations owed to us by our general partner and its affiliates.

Fiduciary Responsibilities

Our general partner is accountable to us and our unitholders as a fiduciary. Fiduciary duties owed to unitholders by our general partner are prescribed by law and our partnership agreement. The Delaware Act provides that Delaware limited partnerships may, in their partnership agreements, restrict, eliminate or otherwise modify the fiduciary duties otherwise owed by a general partner to limited partners and the partnership.

Our partnership agreement contains various provisions modifying and restricting the fiduciary duties that might otherwise be owed by our general partner. These modifications, among other things, restrict the remedies available to unitholders for actions that, without those limitations, might constitute breaches of fiduciary duty, as described below. The following is a summary of the material restrictions of the fiduciary duties owed by our general partner to the limited partners:

State-law fiduciary duty standards Fiduciary duties are generally considered to include an obligation to act in good faith and with due care and loyalty. The duty of care, in the absence of a provision in a partnership agreement providing otherwise, would generally require a general partner to act for the partnership in the same manner as a prudent person would act on his own behalf. The duty of loyalty, in the absence of a provision in a partnership agreement providing otherwise, would generally prohibit a general partner of a Delaware limited partnership from taking any action or engaging in any transaction where a conflict of interest is present.

Partnership agreement modified standards Our partnership agreement contains provisions that waive or consent to conduct by our general partner and its affiliates that might otherwise raise issues about compliance with fiduciary duties or applicable law. For example, our partnership agreement provides that when our general partner is acting in its capacity as our general partner, as opposed to in its individual capacity, it must act in “good faith” and will not be subject to any other standard under applicable law. In addition, when our general partner is acting in its individual capacity, as opposed to in its capacity as our general partner, it may act without any fiduciary obligation to us or the unitholders whatsoever. These standards reduce the obligations to which our general partner would otherwise be held.

32

Our partnership agreement generally provides that affiliated transactions and resolutions of conflicts of interest not involving a vote of unitholders and that are not approved by the conflicts committee of the board of directors of our general partner must be:

• on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or

• “fair and reasonable” to us, taking into account the totality of the relationships between the parties involved (including other transactions that may be particularly favorable or advantageous to us).

If our general partner does not seek approval from the conflicts committee and its board of directors determines that the resolution or course of action taken with respect to the conflict of interest satisfies either of the standards set forth in the bullet points above, then it will be presumed that, in making its decision, the board of directors acted in good faith, and in any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. These standards reduce the obligations to which our general partner would otherwise be held.

In addition to the other more specific provisions limiting the obligations of our general partner, our partnership agreement further provides that our general partner and its officers and directors will not be liable for monetary damages to us, our limited partners or assignees for errors of judgment or for any acts or omissions unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that the general partner or its officers and directors acted in bad faith or engaged in fraud, willful misconduct or gross negligence.

Rights and remedies of unitholders under Delaware law The Delaware Act generally provides that a limited partner may institute legal action on behalf of the partnership to recover damages from a third party where a general partner has refused to institute the action or where an effort to cause a general partner to do so is not likely to succeed. These actions include actions against a general partner for breach of its fiduciary duties or of the partnership agreement. In addition, the statutory or case law of some jurisdictions may permit a limited partner to institute legal action on behalf of himself and all other similarly situated limited partners to recover damages from a general partner for violations of its fiduciary duties to the limited partners.

In order to become one of our limited partners, a common unitholder is required to agree to be bound by the provisions in our partnership agreement, including the provisions discussed above. This is in accordance with the policy of the Delaware Act favoring the principle of freedom of contract and the enforceability of partnership agreements. The failure of a limited partner or assignee to sign a partnership agreement does not render the partnership agreement unenforceable against that person.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

This section summarizes the material U.S. federal income tax consequences that may be relevant to prospective common unitholders and is based upon current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), existing and proposed Treasury regulations thereunder (the “Treasury Regulations”), and current administrative rulings and court decisions, all of which are subject to change. Changes in these authorities may cause the federal income tax consequences to a prospective common unitholder to vary substantially from those described below. Unless the context otherwise requires, references in this section to “we” or “us” are references to Sunoco Logistics Partners L.P. and Sunoco Logistics Partners Operations L.P., our operating partnership.

Legal conclusions contained in this section, unless otherwise noted, are the opinion of Vinson & Elkins L.L.P. and are based on the accuracy of representations made by us to them for this purpose. However, this section does not address all federal income tax matters that affect us or our unitholders and does not describe the application of the alternative minimum tax that may be applicable to certain unitholders. Furthermore, this section focuses on unitholders who are individual citizens or residents of the United States (for federal income tax purposes), who have the U.S. dollar as their functional currency, who use the calendar year as their taxable year, and who hold units as capital assets (generally, property that is held for investment). This section has limited applicability to corporations, partnerships (including entities treated as partnerships for federal income tax purposes), estates, trusts, non-resident aliens or other unitholders subject to specialized tax treatment, such as tax-exempt institutions, non-U.S. persons, individual retirement accounts (“IRAs”), employee benefit plans, real estate investment trusts or mutual funds. Accordingly, we encourage each common unitholder to consult the unitholder’s own tax advisor in analyzing the federal, state, local and non-U.S. tax consequences particular to that common unitholder resulting from ownership or disposition of units and potential changes in applicable tax laws.

We will rely on the opinions and advice of Vinson & Elkins L.L.P. with respect to the matters described herein. An opinion of counsel represents only that counsel’s best legal judgment and does not bind the Internal Revenue Service (the “IRS”) or a court. Accordingly, the opinions and statements made herein may not be sustained by a court if contested by the IRS. Any such contest of the matters described herein may materially and adversely impact the market for units and the prices at which our units trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders because the costs will reduce our cash available for distribution. Furthermore, the tax consequences of an investment in us may be significantly modified by future legislative or administrative changes or court decisions, which may be retroactively applied.

For the reasons described below, Vinson & Elkins L.L.P. has not rendered an opinion with respect to the following federal income tax issues: (1) the treatment of a unitholder whose units are the subject of a securities loan (e.g., a loan to a short seller to cover a short sale of units) (please read “—Tax Consequences of Unit Ownership—Treatment of Securities Loans”); (2) whether our monthly convention for allocating taxable income and losses is permitted by existing Treasury Regulations (please read “—Disposition of Common Units—Allocations Between Transferors and Transferees”); and (3) whether our method for taking into account Section 743 adjustments is sustainable in certain cases (please read “—Tax Consequences of Unit Ownership—Section 754 Election” and “—Uniformity of Units”).

Partnership Status

We expect to be treated as a partnership for federal income tax purposes and, therefore, generally will not be liable for entity-level federal income taxes. Instead, as described below, each of our common unitholders will take into account its respective share of our items of income, gain, loss and deduction in computing its federal income tax liability as if the common unitholder had earned such income directly, even if no cash distributions are made to the common unitholder. Distributions by us to a common unitholder generally will not give rise to income or gain taxable to such unitholder, unless the amount of cash distributed to a common unitholder exceeds the unitholder’s adjusted tax basis in its units.

34

Section 7704 of the Code generally provides that publicly traded partnerships will be treated as corporations for federal income tax purposes. However, if 90% or more of a partnership’s gross income for every taxable year it is publicly traded consists of “qualifying income,” the partnership may continue to be treated as a partnership for federal income tax purposes (the “Qualifying Income Exception”). Qualifying income includes income and gains derived from the exploration, development, mining or production, processing, transportation, and marketing of natural resources, including oil, gas, and products thereof. Other types of qualifying income include interest (other than from a financial business), dividends, gains from the sale of real property and gains from the sale or other disposition of capital assets held for the production of qualifying income. We estimate that approximately 3% of our current gross income is not qualifying income; however, this estimate could change from time to time.

Based upon factual representations made by us and our general partner regarding the composition of our income and the other representations set forth below, Vinson & Elkins L.L.P. is of the opinion that we will be treated as a partnership and each of our non-corporate subsidiaries will be treated as a partnership or will be disregarded as an entity separate from us for federal income tax purposes. In rendering its opinion, Vinson & Elkins L.L.P. has relied on factual representations made by us and our general partner. The representations made by us and our general partner upon which Vinson & Elkins L.L.P. has relied include, without limitation:

(a) Neither we nor any of our partnership or limited liability company subsidiaries has elected to be treated as a corporation for federal income tax purposes; and

(b) For each taxable year, more than 90% of our gross income has been and will be income of a character that Vinson & Elkins L.L.P. has opined is “qualifying income” within the meaning of Section 7704(d) of the Code.

We believe that these representations are true and will be true in the future.

If we fail to meet the Qualifying Income Exception, other than a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery (in which case the IRS may also require us to make adjustments with respect to our common unitholders or pay other amounts), we will be treated as transferring all of our assets, subject to liabilities, to a newly formed corporation, on the first day of the year in which we fail to meet the Qualifying Income Exception, in return for stock in that corporation and then distributing that stock to our common unitholders in liquidation of their units. This deemed contribution and liquidation generally will not result in the recognition of taxable income by our common unitholders or us so long as our liabilities do not exceed the tax basis of our assets. Thereafter, we would be treated as an association taxable as a corporation for federal income tax purposes.

The present U.S. federal income tax treatment of publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial changes or differing interpretations at any time. For example, from time to time, members of the U.S. Congress and the President propose and consider substantive changes to the existing federal income tax laws that affect publicly traded partnerships, including the elimination of the Qualifying Income Exception upon which we rely for our treatment as a partnership for federal income tax purposes.

In addition, the IRS has issued proposed regulations regarding qualifying income under Section 7704(d)(1)(E) of the Code (the “Proposed Regulations”). We do not believe the Proposed Regulations affect our ability to qualify as a publicly traded partnership. However, there are no assurances that final regulations will not include changes that interpret Section 7704(d)(1)(E) in a manner that is contrary to the Proposed Regulations, which could modify the amount of our gross income that we are able to treat as qualifying income for the purposes of the Qualifying Income Exception. We are unable to predict whether any such changes will ultimately be enacted. However, it is possible that a change in law could affect us and may be applied retroactively. Any such changes could negatively impact the value of an investment in our common units.

35

If for any reason we are taxable as a corporation in any taxable year, our items of income, gain, loss and deduction would be taken into account by us in determining the amount of our liability for federal income tax, rather than being passed through to our common unitholders. Our taxation as a corporation would materially reduce the cash available for distribution to unitholders and thus would likely substantially reduce the value of our units. Any distribution made to a common unitholder at a time we are treated as a corporation would be (i) a taxable dividend to the extent of our current or accumulated earnings and profits, then (ii) a nontaxable return of capital to the extent of the unitholder’s tax basis in its units, and thereafter (iii) taxable capital gain.

The remainder of this discussion is based on the opinion of Vinson & Elkins L.L.P. that we will be treated as a partnership for federal income tax purposes.

Limited Partner Status

Unitholders who have become limited partners of Sunoco Logistics Partners L.P. will be treated as partners of Sunoco Logistics Partners L.P. for federal income tax purposes. Also, assignees who have executed and delivered transfer applications, and are awaiting admission as limited partners, and unitholders whose common units are held in street name or by a nominee and who have the right to direct the nominee in the exercise of all substantive rights attendant to the ownership of their common units will be treated as partners of Sunoco Logistics Partners L.P. for federal income tax purposes. As there is no direct or indirect controlling authority addressing assignees of common units who are entitled to execute and deliver transfer applications and thereby become entitled to direct the exercise of attendant rights, but who fail to execute and deliver transfer applications, Vinson & Elkins L.L.P.’s opinion does not extend to these persons. Furthermore, a purchaser or other transferee of common units who does not execute and deliver a transfer application may not receive some federal income tax information or reports furnished to record holders of common units unless the common units are held in a nominee or street name account and the nominee or broker has executed and delivered a transfer application for those common units.

For a discussion related to the risks of losing partner status as a result of short sales, please read “—Tax Consequences of Unit Ownership—Treatment of Securities Loans.” Common unitholders who are not treated as partners in us as described above are urged to consult their own tax advisors with respect to the tax consequences applicable to them under the circumstances.

Tax Consequences of Unit Ownership

Flow-Through of Taxable Income. Subject to the discussion below under “—Entity-Level Collections of Unitholder Taxes” with respect to payments we may be required to make on behalf of our common unitholders, we will not pay any federal income tax. Rather, each common unitholder will be required to report on its income tax return its share of our income, gains, losses and deductions for our taxable year or years ending with or within its taxable year without regard to whether we make cash distributions to such unitholder. Consequently, we may allocate income to a common unitholder even if that unitholder has not received a cash distribution.

Treatment of Distributions. Distributions made by us to a common unitholder generally will not be taxable to the common unitholder, unless such distributions are of cash or marketable securities that are treated as cash and exceed the common unitholder’s tax basis in its units, in which case the common unitholder will recognize gain taxable in the manner described below under “—Disposition of Common Units.”

Any reduction in a common unitholder’s share of our nonrecourse liabilities will be treated as a distribution by us of cash to that common unitholder. A decrease in a common unitholder’s percentage interest in us because of our issuance of additional units will decrease the common unitholder’s share of our nonrecourse liabilities. For purposes of the foregoing, a common unitholder’s share of our nonrecourse liabilities generally will be based upon that common unitholder’s share of the unrealized appreciation (or depreciation) in our assets, to the extent thereof, with any excess liabilities allocated based on the common unitholder’s share of our profits. Please read “—Disposition of Common Units.”

36

A non-pro rata distribution of money or property (including a deemed distribution described above) may cause a common unitholder to recognize ordinary income, if the distribution reduces the common unitholder’s share of our “unrealized receivables,” including depreciation recapture and substantially appreciated “inventory items,” both as defined in Section 751 of the Code (“Section 751 Assets”).

To the extent of such reduction, the common unitholder would be deemed to receive its proportionate share of the Section 751 Assets and exchange such assets with us in return for an allocable portion of the non-pro rata distribution. This latter deemed exchange generally will result in the common unitholder’s realization of ordinary income in an amount equal to the excess of (1) the non-pro rata portion of that distribution over (2) the common unitholder’s tax basis (generally zero) in the Section 751 Assets deemed to be relinquished in the exchange.

Basis of Common Units. A unitholder’s tax basis in its units initially will be the amount it paid for those units plus its initial share of our liabilities. That basis generally will be (i) increased by the common unitholder’s share of our income and any increases in such unitholder’s share of our “nonrecourse liabilities” (liabilities for which no partner, including our general partner, bears the economic risk of loss), and (ii) decreased, but not below zero, by distributions to it, by its share of our losses, any decreases in its share of our nonrecourse liabilities and its share of our expenditures that are neither deductible nor required to be capitalized.

Limitations on Deductibility of Losses. A unitholder may not be entitled to deduct the full amount of loss we allocate to it because its share of our losses will be limited to the lesser of (i) the common unitholder’s tax basis in its units and (ii) in the case of a common unitholder that is an individual, estate, trust or certain types of closely-held corporations, the amount for which the unitholder is considered to be “at risk” with respect to our activities. In general, a common unitholder will be at risk to the extent of its tax basis in its units, reduced by (1) any portion of that basis attributable to the unitholder’s share of our liabilities, (2) any portion of that basis representing amounts otherwise protected against loss because of a guarantee, stop loss agreement or similar arrangement and (3) any amount of money the unitholder borrows to acquire or hold its units, if the lender of those borrowed funds owns an interest in us, is related to another unitholder or can look only to the units for repayment. A unitholder subject to the at risk limitation must recapture losses deducted in previous years to the extent that distributions (including distributions deemed to result from a reduction in a unitholder’s share of nonrecourse liabilities) cause the unitholder’s at risk amount to be less than zero at the end of any taxable year.

Losses disallowed to a unitholder or recaptured as a result of the basis or at risk limitations will carry forward and will be allowable as a deduction in a later year to the extent that the unitholder’s tax basis or at risk amount, whichever is the limiting factor, is subsequently increased. Upon a taxable disposition of units, any gain recognized by a unitholder can be offset by losses that were previously suspended by the at-risk limitation but not losses suspended by the basis limitation. Any loss previously suspended by the at risk limitation in excess of that gain can no longer be used and will not be available to offset a unitholder’s salary or active business income.

In addition to the basis and at risk limitations, passive activity loss limitations generally limit the deductibility of losses incurred by individuals, estates, trusts, some closely held corporations and personal service corporations from “passive activities” (generally, trade or business activities in which the taxpayer does not materially participate). The passive loss limitations are applied separately with respect to each publicly-traded partnership. Consequently, any passive losses we generate will only be available to offset our passive income generated in the future and will not be available to offset income from other passive activities or investments, including any dividend or interest income we derive or from our investments or investments in other publicly-traded partnerships or salary or active business income. Passive losses that are not deductible because they exceed a unitholder’s share of income we generate may be deducted in full when the unitholder disposes of all of its units in a fully taxable transaction with an unrelated party. The passive activity loss rules are applied after other applicable limitations on deductions, including the at risk and basis limitations.

37

Limitations on Interest Deductions. The deductibility of a non-corporate taxpayer’s “investment interest expense” is generally limited to the amount of that taxpayer’s “net investment income.” Investment interest expense includes:

(a) interest on indebtedness properly allocable to property held for investment;

(b) our interest expense attributed to portfolio income; and

(c) the portion of interest expense incurred to purchase or carry an interest in a passive activity to the extent attributable to portfolio income.

The computation of a unitholder’s investment interest expense will take into account interest on any margin account borrowing or other loan incurred to purchase or carry a unit. Net investment income includes gross income from property held for investment and amounts treated as portfolio income under the passive loss rules, less deductible expenses, other than interest, directly connected with the production of investment income, but generally does not include gains attributable to the disposition of property held for investment or (if applicable) qualified dividend income. The IRS has indicated that the net passive income earned by a publicly traded partnership will be treated as investment income to its unitholders. In addition, the unitholder’s share of our portfolio income will be treated as investment income.

Entity-Level Collections of Unitholder Taxes. If we are required or elect under applicable law to pay any federal, state, local or foreign income tax on behalf of any unitholder or our general partner or any former unitholder, we are authorized to pay those taxes from our funds. That payment, if made, will be treated as a distribution of cash to the unitholder on whose behalf the payment was made. If the payment is made on behalf of a person whose identity cannot be determined, we are authorized to treat the payment as a distribution to all current unitholders. We are authorized to amend our partnership agreement in the manner necessary to maintain uniformity of intrinsic tax characteristics of units and to adjust later distributions, so that after giving effect to these distributions, the priority and characterization of distributions otherwise applicable under our partnership agreement is maintained as nearly as is practicable. Payments by us as described above could give rise to an overpayment of tax on behalf of an individual unitholder in which event the unitholder would be required to file a claim in order to obtain a credit or refund.

Allocation of Income, Gain, Loss and Deduction. In general, if we have a net profit, our items of income, gain, loss and deduction will be allocated among our general partner and the unitholders in accordance with their percentage interests in us. At any time that incentive distributions are made to our general partner, gross income will be allocated to the recipients to the extent of these distributions. If we have a net loss, that loss will be allocated first to our general partner and the unitholders in accordance with their percentage interests in us to the extent of their positive capital accounts and, second, to our general partner.

Specified items of our income, gain, loss and deduction will be allocated under Section 704(c) of the Code to account for any difference between the tax basis and fair market value of our assets at the time such assets are contributed to us and at the time of any subsequent offering of our units (a “Book-Tax Disparity”). In addition, items of recapture income will be specially allocated to the extent possible to the common unitholder who was allocated the deduction giving rise to that recapture income in order to minimize the recognition of ordinary income by other unitholders.

An allocation of items of our income, gain, loss or deduction, generally must have “substantial economic effect” as determined under Treasury Regulations. If an allocation does not have substantial economic effect, it will be reallocated to our common unitholders the basis of their interests in us, which will be determined by taking into account all the facts and circumstances, including:

(a) his relative contributions to us;

(b) the interests of all the partners in profits and losses;

(c) the interest of all the partners in cash flow; and

38

(d) the rights of all the partners to distributions of capital upon liquidation.

Vinson & Elkins L.L.P. is of the opinion that, with the exception of the issues described in “—Section 754 Election” and “—Disposition of Common Units—Allocations Between Transferors and Transferees,” allocations under our partnership agreement will have substantial economic effect.

Treatment of Securities Loans. A common unitholder whose units are loaned (for example, a loan to “short seller” to cover a short sale of units) may be treated as having disposed of those units. If so, such common unitholder would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition. As a result, during this period, (i) any of our income, gain, loss or deduction allocated to those units would not be reportable by the lending unitholder and (ii) any cash distributions received by the common unitholder as to those units may be treated as ordinary taxable income.

Due to a lack of controlling authority, Vinson & Elkins L.L.P. has not rendered an opinion regarding the tax treatment of a common unitholder that enters into a securities loan with respect to its units. Common unitholders desiring to assure their status as partners and avoid the risk of income recognition from a loan of their units are urged to modify any applicable brokerage account agreements to prohibit their brokers from borrowing and lending their units. The IRS has announced that it is studying issues relating to the tax treatment of short sales of partnership interests. Please read “—Disposition of Common Units—Recognition of Gain or Loss.”

Tax Rates. Under current law, the highest marginal federal income tax rates for individuals applicable to ordinary income and long-term capital gains (generally, gains from the sale or exchange of certain investment assets held for more than one year) are 39.6% and 20%, respectively. These rates are subject to change by new legislation at any time.

In addition, a 3.8% net investment income tax (“NIIT”) applies to certain net investment income earned by individuals, estates and trusts. For these purposes, net investment income generally includes a common unitholder’s allocable share of our income and gain realized by a common unitholder from a sale of units. In the case of an individual, the tax will be imposed on the lesser of (i) the common unitholder’s net investment income from all investments and (ii) the amount by which the common unitholder’s modified adjusted gross income exceeds $250,000 (if the unitholder is married and filing jointly or a surviving spouse), $125,000 (if married filing separately) or $200,000 (if the unitholder is unmarried or in any other case). In the case of an estate or trust, the tax will be imposed on the lesser of (i) undistributed net investment income and (ii) the excess adjusted gross income over the dollar amount at which the highest income tax bracket applicable to an estate or trust begins.

Section 754 Election. We have made the election permitted by Section 754 of the Code that permits us to adjust the tax bases in our assets as to specific purchased units under Section 743(b) of the Code to reflect the unit purchase price. The Section 743(b) adjustment separately applies to each purchaser of units based upon the values and bases of our assets at the time of the relevant purchase. The Section 743(b) adjustment does not apply to a person who purchases units directly from us. For purposes of this discussion, a common unitholder’s basis in our assets will be considered to have two components: (1) its share of the tax basis in our assets as to all common unitholders (“common basis”) and (2) its Section 743(b) adjustment to that tax basis (which may be positive or negative).

Under Treasury Regulations, a Section 743(b) adjustment attributable to property depreciable under Section 168 of the Code, such as our storage assets, may be amortizable over the remaining cost recovery period for such property, while a Section 743(b) adjustment attributable to properties subject to depreciation under Section 167 of the Code, must be amortized straight-line or using the 150% declining balance method. As a result, if we owned any assets subject to depreciation under Section 167 of the Code, the amortization rates could give rise to differences in the taxation of common unitholders purchasing units from us and common unitholders purchasing from other unitholders.

39

Under our partnership agreement, we are authorized to take a position to preserve the uniformity of units even if that position is not consistent with these or any other Treasury Regulations. Please read “—Disposition of Common Units—Uniformity of Units.” Consistent with this authority, we intend to treat properties depreciable under Section 167, if any, in the same manner as properties depreciable under Section 168 for this purpose. These positions are consistent with the methods employed by other publicly traded partnerships but are inconsistent with the existing Treasury Regulations, and Vinson & Elkins L.L.P. has not opined on the validity of this approach.

The IRS may challenge our position with respect to depreciating or amortizing the Section 743(b) adjustment we take to preserve the uniformity of units due to lack of controlling authority. Because a common unitholder’s tax basis for its units is reduced by its share of our items of deduction or loss, any position we take that understates deductions will overstate a common unitholder’s basis in its units, and may cause the common unitholder to understate gain or overstate loss on any sale of such units. Please read “—Disposition of Common Units—Recognition of Gain or Loss.” If a challenge to such treatment were sustained, the gain from the sale of units may be increased without the benefit of additional deductions.

The calculations involved in the Section 754 election are complex and will be made on the basis of assumptions as to the value of our assets and other matters. The IRS could seek to reallocate some or all of any Section 743(b) adjustment we allocated to our assets subject to depreciation to goodwill or nondepreciable assets. Goodwill, as an intangible asset, is generally nonamortizable or amortizable over a longer period of time or under a less accelerated method than our tangible assets. We cannot assure any common unitholder that the determinations we make will not be successfully challenged by the IRS or that the resulting deductions will not be reduced or disallowed altogether. Should the IRS require a different tax basis adjustment to be made, and should, in our opinion, the expense of compliance exceed the benefit of the election, we may seek permission from the IRS to revoke our Section 754 election. If permission is granted, a subsequent purchaser of units may be allocated more income than it would have been allocated had the election not been revoked.

Tax Treatment of Operations

Accounting Method and Taxable Year. We use the year ending December 31 as our taxable year and the accrual method of accounting for federal income tax purposes. Each unitholder will be required to include in income his share of our income, gain, loss and deduction for our taxable year ending within or with his taxable year. In addition, a unitholder who has a taxable year ending on a date other than December 31 and who disposes of all of his units following the close of our taxable year but before the close of his taxable year must include his share of our income, gain, loss and deduction in income for his taxable year, with the result that he will be required to include in income for his taxable year his share of more than twelve months of our income, gain, loss and deduction. Please read “—Disposition of Common Units—Allocations Between Transferors and Transferees.”

Tax Basis, Depreciation and Amortization. The tax basis of our assets will be used for purposes of computing depreciation and cost recovery deductions and, ultimately, gain or loss on the disposition of these assets. The federal income tax burden associated with the difference between the fair market value of our assets and their tax basis immediately prior to an offering will be borne by our partners holding interests in us prior to this offering. Please read “—Tax Consequences of Unit Ownership—Allocation of Income, Gain, Loss and Deduction.”

If we dispose of depreciable property by sale, foreclosure or otherwise, all or a portion of any gain, determined by reference to the amount of depreciation previously deducted and the nature of the property, may be subject to the recapture rules and taxed as ordinary income rather than capital gain. Similarly, a common unitholder who has taken cost recovery or depreciation deductions with respect to property we own will likely be required to recapture some or all of those deductions as ordinary income upon a sale of its interest in us. Please read “—Tax Consequences of Unit Ownership—Allocation of Income, Gain, Loss and Deduction” and “—Disposition of Common Units—Recognition of Gain or Loss.”

40

The costs we incur in offering and selling our units (called “syndication expenses”) must be capitalized and cannot be deducted currently, ratably or upon our termination. While there are uncertainties regarding the classification of costs as organization expenses, which may be amortized by us, and as syndication expenses, which may not be amortized by us, the underwriting discounts and commissions we incur will be treated as syndication expenses.

Valuation and Tax Basis of Our Properties. The federal income tax consequences of the ownership and disposition of units will depend in part on our estimates of the relative fair market values and the initial tax bases of our assets. Although we may from time to time consult with professional appraisers regarding valuation matters, we will make many of the relative fair market value estimates and tax basis determinations ourselves. These estimates and determinations of tax basis are subject to challenge and will not be binding on the IRS or the courts. If the estimates of fair market value or basis are later found to be incorrect, the character and amount of items of income, gain, loss or deduction previously reported by common unitholders could change, and common unitholders could be required to adjust their tax liability for prior years and incur interest and penalties with respect to those adjustments.

Disposition of Common Units

Recognition of Gain or Loss. A common unitholder will be required to recognize gain or loss on a sale of units equal to the difference between the common unitholder’s amount realized and tax basis for the units sold. A common unitholder’s amount realized will equal the sum of the cash or the fair market value of other property it receives plus its share of our liabilities with respect to such units. Because the amount realized includes a common unitholder’s share of our liabilities, the gain recognized on the sale of units could result in a tax liability in excess of any cash received from the sale.

Except as noted below, gain or loss recognized by a common unitholder on the sale or exchange of a unit held for more than one year generally will be taxable as long-term capital gain or loss. However, gain or loss recognized on the disposition of units will be separately computed and taxed as ordinary income or loss under Section 751 of the Code to the extent attributable to Section 751 Assets, primarily depreciation recapture. Ordinary income attributable to Section 751 Assets may exceed net taxable gain realized on the sale of a unit and may be recognized even if there is a net taxable loss realized on the sale of a unit. Thus, a common unitholder may recognize both ordinary income and a capital loss upon a sale of units. Net capital loss may offset capital gains and, in the case of individuals, up to $3,000 of ordinary income per year.

The IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all those interests. Upon a sale or other disposition of less than all of those interests, a portion of that tax basis must be allocated to the interests sold using an “equitable apportionment” method, which generally means that the tax basis allocated to the interest sold equals an amount that bears the same relation to the partner’s tax basis in its entire interest in the partnership as the value of the interest sold bears to the value of the partner’s entire interest in the partnership.

Treasury Regulations under Section 1223 of the Code allow a selling common unitholder who can identify units transferred with an ascertainable holding period to elect to use the actual holding period of the units transferred. Thus, according to the ruling discussed above, a common unitholder will be unable to select high or low basis units to sell as would be the case with corporate stock, but, according to the Treasury Regulations, it may designate specific units sold for purposes of determining the holding period of units transferred. A common unitholder electing to use the actual holding period of units transferred must consistently use that identification method for all subsequent sales or exchanges of our units. A common unitholder considering the purchase of additional units or a sale of units purchased in separate transactions is urged to consult its tax advisor as to the possible consequences of this ruling and application of the Treasury Regulations.

41

Specific provisions of the Code affect the taxation of some financial products and securities, including partnership interests, by treating a taxpayer as having sold an “appreciated” partnership interest, one in which gain would be recognized if it were sold, assigned or terminated at its fair market value, if the taxpayer or related persons enter(s) into:

• a short sale;

• an offsetting notional principal contract; or

• a futures or forward contract with respect to the partnership interest or substantially identical property.

Moreover, if a taxpayer has previously entered into a short sale, an offsetting notional principal contract or a futures or forward contract with respect to the partnership interest, the taxpayer will be treated as having sold that position if the taxpayer or a related person then acquires the partnership interest or substantially identical property. The Secretary of the Treasury is also authorized to issue regulations that treat a taxpayer that enters into transactions or positions that have substantially the same effect as the preceding transactions as having constructively sold the financial position.

Allocations Between Transferors and Transferees. In general, our taxable income or loss will be determined annually, will be prorated on a monthly basis and will be subsequently apportioned among the common unitholders in proportion to the number of units owned by each of them as of the opening of the applicable exchange on the first business day of the month (the “Allocation Date”). Nevertheless, we allocate certain deductions for depreciation of capital additions based upon the date the underlying property is placed in service, and gain or loss realized on a sale or other disposition of our assets or, in the discretion of the general partner, any other extraordinary item of income, gain, loss or deduction will be allocated among the common unitholders on the Allocation Date in the month in which such income, gain, loss or deduction is recognized. As a result, a common unitholder transferring units may be allocated income, gain, loss and deduction realized after the date of transfer.

Although simplifying conventions are contemplated by the Code and most publicly traded partnerships use similar simplifying conventions, the use of this method may not be permitted under existing Treasury Regulations. Recently, however, the Department of the Treasury and the IRS issued final Treasury Regulations that provide a safe harbor pursuant to which a publicly traded partnership may use a similar monthly simplifying convention to allocate tax items among transferor and transferee common unitholders. We are currently evaluating these regulations, which apply beginning with our taxable year that begins on January 1, 2016. Nonetheless, the regulations do not specifically authorize the proration method we have adopted. Accordingly, Vinson & Elkins L.L.P. is unable to opine on the validity of this method of allocating income and deductions between transferee and transferor common unitholders. If the IRS were to determine that our method is not allowed under the Treasury Regulations, or only applies to transfers of less than all of the common unitholder’s interest, our taxable income or losses might be reallocated among the common unitholders. We are authorized to revise our method of allocation between transferee and transferor common unitholders, as well as among common unitholders whose interests vary during a taxable year, to conform to a method permitted under the Treasury Regulations.

A common unitholder who disposes of units prior to the record date set for a cash distribution for that quarter will be allocated items of our income, gain, loss and deduction attributable to the month of disposition but will not be entitled to receive a cash distribution for that period.

Notification Requirements. A unitholder who sells or purchases any units is generally required to notify us in writing of that transaction within 30 days after the transaction (or, if earlier, January 15 of the year following the transaction). Upon receiving such notifications, we are required to notify the IRS of that transaction and to furnish specified information to the transferor and transferee. Failure to notify us of a transfer of units may, in some cases, lead to the imposition of penalties. However, these reporting requirements do not apply to a sale by an individual who is a citizen of the United States and who effects the sale through a broker who will satisfy such requirements.

42

Constructive Termination. We will be considered to have terminated our partnership for federal income tax purposes upon the sale or exchange of 50% or more of the total interests in our capital and profits within a twelve-month period. For such purposes, multiple sales of the same unit are counted only once. A constructive termination results in the closing of our taxable year for all common unitholders. In the case of a common unitholder reporting on a taxable year other than a fiscal year ending December 31, the closing of our taxable year may result in more than twelve months of our taxable income or loss being includable in such common unitholder’s taxable income for the year of termination.

A constructive termination occurring on a date other than December 31 will result in us filing two tax returns for one fiscal year and the cost of the preparation of these returns will be borne by all common unitholders. However, pursuant to an IRS relief procedure the IRS may allow, among other things, a constructively terminated partnership to provide a single Schedule K-1 for the calendar year in which a termination occurs. We would be required to make new tax elections after a termination, including a new election under Section 754 of the Code, and a termination would result in a deferral of our deductions for depreciation and thus may increase the taxable income allocable to our unitholders. A termination could also result in penalties if we were unable to determine that the termination had occurred. Moreover, a termination might either accelerate the application of, or subject us to, any tax legislation enacted before the termination.

Uniformity of Units. Because we cannot match transferors and transferees of units and for other reasons, we must maintain uniformity of the economic and tax characteristics of the units to a purchaser of these units. In the absence of uniformity, we may be unable to completely comply with a number of federal income tax requirements, both statutory and regulatory. A lack of uniformity could result from a literal application of Treasury Regulation Section 1.167(c)-1(a)(6), which is not anticipated to apply to a material portion of our assets. Any non-uniformity could have a negative impact on the value of the units. Please read “—Tax Consequences of Unit Ownership—Section 754 Election.”

If necessary to preserve the uniformity of our units, our partnership agreement permits our general partner to take positions in filing our tax returns even when contrary to a literal application of regulations like the one described above. These positions may include reducing for some common unitholders the depreciation, amortization or loss deductions to which they would otherwise be entitled or reporting a slower amortization of Section 743(b) adjustments for some common unitholders than that to which they would otherwise be entitled. The general partner does not anticipate needing to take such positions, but if they were necessary, Vinson & Elkins L.L.P. would be unable to opine as to validity of such filing positions in the absence of direct and controlling authority.

A common unitholder’s basis in units is reduced by its share of our deductions (whether or not such deductions were claimed on an individual income tax return) so that any position that we take that understates deductions will overstate the common unitholder’s basis in its units, and may cause the common unitholder to understate gain or overstate loss on any sale of such units. Please read “—Disposition of Common Units—Recognition of Gain or Loss” above and “—Tax Consequences of Unit Ownership—Section 754 Election” above. The IRS may challenge one or more of any positions we take to preserve the uniformity of units. If such a challenge were sustained, the uniformity of units might be affected, and, under some circumstances, the gain from the sale of units might be increased without the benefit of additional deductions.

Tax-Exempt Organizations and Other Investors

Ownership of common units by employee benefit plans and other tax-exempt organizations as well as by non-resident alien individuals, non-U.S. corporations and other non-U.S. persons (collectively, “Non-U.S. Unitholders”) raises issues unique to those investors and, as described below, may have substantially adverse tax consequences to them. Prospective unitholders that are tax-exempt entities or Non-U.S. Unitholders should consult their tax advisors before investing in our common units. Employee benefit plans and most other tax-exempt organizations, including IRAs and other retirement plans, are subject to federal income tax on unrelated business taxable income. Virtually all of our income will be unrelated business taxable income and will be taxable to a tax-exempt unitholder.

43

Non-U.S. Unitholders are taxed by the United States on income effectively connected with a U.S. trade or business (“effectively connected income”) and on certain types of U.S.-source non-effectively connected income (such as dividends), unless exempted or further limited by an income tax treaty. Non-U.S. Unitholders will be considered to be engaged in business in the United States because of their ownership of our units. Furthermore, it is probable that they will be deemed to conduct such activities through permanent establishments in the U.S. within the meaning of applicable tax treaties. Consequently, they will be required to file federal tax returns to report their share of our income, gain, loss or deduction and pay federal income tax on their share of our net income or gain. Moreover, under rules applicable to publicly traded partnerships, distributions to Non-U.S. Unitholders are subject to withholding at the highest applicable effective tax rate. Each Non-U.S. Unitholder must obtain a taxpayer identification number from the IRS and submit that number to our transfer agent on a Form W-8BEN or applicable substitute form in order to obtain credit for these withholding taxes.

In addition, because a Non-U.S. Unitholder classified as a corporation will be treated as engaged in a United States trade or business, that corporation may be subject to the U.S. branch profits tax at a rate of 30%, in addition to regular federal income tax, on its share of our income and gain as adjusted for changes in the foreign corporation’s “U.S. net equity” to the extent reflected in the corporation’s effectively connected earnings and profits. That tax may be reduced or eliminated by an income tax treaty between the United States and the country in which the foreign corporate unitholder is a “qualified resident.” In addition, this type of unitholder is subject to special information reporting requirements under Section 6038C of the Code.

A Non-U.S. Unitholder who sells or otherwise disposes of a unit will be subject to federal income tax on gain realized from the sale or disposition of that common unit to the extent the gain is effectively connected with a U.S. trade or business of the Non-U.S. Unitholder. Under a ruling published by the IRS interpreting the scope of “effectively connected income,” gain recognized by a Non-U.S. Unitholder from the sale of its interest in a partnership that is engaged in a trade or business in the United States will be considered to be “effectively connected” with a U.S. trade or business. Thus, part or all of a Non-U.S. Unitholder’s gain from the sale or other disposition of its units may be treated as effectively connected with a common unitholder’s indirect U.S. trade or business constituted by its investment in us. Moreover, under the Foreign Investment in Real Property Tax Act, a Non-U.S. Unitholder generally will be subject to federal income tax upon the sale or disposition of a common unit if (i) it owned (directly or indirectly constructively applying certain attribution rules) more than 5% of our common units at any time during the five-year period ending on the date of such disposition and (ii) 50% or more of the fair market value of our worldwide real property interests and our other assets used or held for use in a trade or business consisted of U.S. real property interests (which include U.S. real estate, including land, improvements, and associated personal property, and interests in certain entities holding U.S. real estate) at any time during the shorter of the period during which such unitholder held the units or the 5-year period ending on the date of disposition. More than 50% of our assets may consist of U.S. real property interests. Therefore, Non-U.S. Unitholders may be subject to federal income tax on gain from the sale or disposition of their common units.

Administrative Matters

Information Returns and Audit Procedures. We intend to furnish to each common unitholder, within 90 days after the close of each taxable year, specific tax information, including a Schedule K-1, which describes its share of our income, gain, loss and deduction for our preceding taxable year. In preparing this information, which will not be reviewed by counsel, we will take various accounting and reporting positions, some of which have been mentioned earlier, to determine each common unitholder’s share of income, gain, loss and deduction. We cannot assure our common unitholders that those positions will yield a result that conforms to the requirements of the Code, Treasury Regulations or administrative interpretations of the IRS.

The IRS may audit our federal income tax information returns. Neither we, nor Vinson & Elkins L.L.P. can assure prospective common unitholders that the IRS will not successfully contend in court that those positions are impermissible, and such a contention could negatively affect the value of the units. Adjustments resulting

44

from an IRS audit may require each common unitholder to adjust a prior year’s tax liability, and possibly may result in an audit of its own return. Any audit of a common unitholder’s return could result in adjustments not related to our returns as well as those related to its returns.

Publicly traded partnerships generally are treated as entities separate from their owners for purposes of federal income tax audits, judicial review of administrative adjustments by the IRS and tax settlement proceedings. The tax treatment of partnership items of income, gain, loss and deduction are determined in a partnership proceeding rather than in separate proceedings with the partners. The Code requires that one partner be designated as the “Tax Matters Partner” for these purposes, and our partnership agreement designates our general partner.

The Tax Matters Partner has made and will make elections on our behalf and on behalf of common unitholders. In addition, the Tax Matters Partner can extend the statute of limitations for assessment of tax deficiencies against common unitholders for items in our returns. The Tax Matters Partner may bind a common unitholder with less than a 1% profits interest in us to a settlement with the IRS unless that common unitholder elects, by filing a statement with the IRS, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the common unitholders are bound, of a final partnership administrative adjustment and, if the Tax Matters Partner fails to seek judicial review, judicial review may be sought by any common unitholder having at least a 1% interest in profits or by any group of common unitholders having in the aggregate at least a 5% interest in profits. However, only one action for judicial review will go forward, and each common unitholder with an interest in the outcome may participate in that action.

A common unitholder must file a statement with the IRS identifying the treatment of any item on its federal income tax return that is not consistent with the treatment of the item on our return. Intentional or negligent disregard of this consistency requirement may subject a common unitholder to substantial penalties.

Nominee Reporting. Persons who hold an interest in us as a nominee for another person are required to furnish to us:

(a) the name, address and taxpayer identification number of the beneficial owner and the nominee;

(b) a statement regarding whether the beneficial owner is:

1. a non-U.S. person;

2. a non-U.S. government, an international organization or any wholly owned agency or instrumentality of either of the foregoing; or

3. a tax-exempt entity;

(c) the amount and description of units held, acquired or transferred for the beneficial owner; and

(d) specific information including the dates of acquisitions and transfers, means of acquisitions and transfers, and acquisition cost for purchases, as well as the amount of net proceeds from dispositions.

Brokers and financial institutions are required to furnish additional information, including whether they are U.S. persons and specific information on units they acquire, hold or transfer for their own account. A penalty of $250 per failure, up to a maximum of $3 million per calendar year, is imposed by the Code for failure to report that information to us. The nominee is required to supply the beneficial owner of the units with the information furnished to us.

Accuracy-Related Penalties. Certain penalties may be imposed as a result of an underpayment of tax that is attributable to one or more specified causes, including negligence or disregard of rules or regulations, substantial understatements of income tax and substantial valuation misstatements. No penalty will be imposed, however, for any portion of an underpayment if it is shown that there was a reasonable cause for the underpayment of that portion and that the taxpayer acted in good faith regarding the underpayment of that portion. We do not anticipate that any accuracy-related penalties will be assessed against us.

45

State, Local, Foreign and Other Tax Considerations

In addition to federal income taxes, common unitholders will be subject to other taxes, including state and local income taxes, unincorporated business taxes, and estate, inheritance or intangibles taxes that may be imposed by the various jurisdictions in which we conduct business or own property or in which the common unitholder is a resident. We currently conduct business or own property in many states in the United States. Most of these states impose an income tax on individuals, corporations and other entities. As we make acquisitions or expand our business, we may own property or conduct business in other states in additional states that impose a personal income tax. Although an analysis of those various taxes is not presented here, each prospective unitholder should consider their potential impact on its investment in us.

A unitholder may be required to file income tax returns and pay income taxes in some or all of the jurisdictions in which we do business or own property, though such unitholder may not be required to file a return and pay taxes in certain jurisdictions because its income from such jurisdictions falls below the jurisdiction’s filing and payment requirement. Further, a common unitholder may be subject to penalties for a failure to comply with any filing or payment requirement applicable to such unitholder. Some of the jurisdictions may require us, or we may elect, to withhold a percentage of income from amounts to be distributed to a common unitholder who is not a resident of the jurisdiction. Withholding, the amount of which may be greater or less than a particular common unitholder’s income tax liability to the jurisdiction, generally does not relieve a nonresident common unitholder from the obligation to file an income tax return.

It is the responsibility of each common unitholder to investigate the legal and tax consequences, under the laws of pertinent states and localities, of its investment in us. Vinson & Elkins L.L.P. has not rendered an opinion on the state, local, or non-U.S. tax consequences of an investment in us. We strongly recommend that each prospective common unitholder consult, and depend on, its own tax counsel or other advisor with regard to those matters. It is the responsibility of each common unitholder to file all tax returns that may be required of the common unitholder.

INVESTMENT IN OUR COMMON UNITS BY EMPLOYEE BENEFIT PLANS

The following is a summary of certain considerations associated with an investment in our common units by an employee benefit plan that is subject to certain additional considerations because the investments of these plans are subject to the fiduciary responsibility and prohibited transaction provisions of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and the prohibited transaction restrictions imposed by Section 4975 of the Code or provisions under any federal, state, local, non-U.S. or other laws, rules or regulations that are similar to such provisions of the Code or ERISA, which we refer to collectively as “Similar Laws.” As used herein, the term “employee benefit plan” includes, but is not limited to, qualified pension, profit-sharing and stock bonus plans, certain Keogh plans, certain simplified employee pension plans and tax deferred annuities, individual retirement accounts or annuities (“IRAs”) or other arrangements established or maintained by an employer or employee organization, and entities whose underlying assets are considered to include “plan assets” of such plans, accounts and arrangements.

This summary is based on the provisions of ERISA and the Code (and related regulations and administrative and judicial interpretations) as of the date of this prospectus. This summary does not purport to be complete, and no assurance can be given that future legislation, court decisions, regulations, rulings or administrative pronouncements will not significantly modify the requirements summarized below. Any of these changes may be retroactive and, therefore, may apply to transactions entered into prior to the date of their enactment or release.

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of an employee benefit plan that is subject to Title I of ERISA or Section 4975 of the Code, which we refer to as an “ERISA Plan,” and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of an ERISA Plan or the management or disposition of the assets of an ERISA Plan, or who renders investment advice for a fee or other compensation to an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

Governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) and non-U.S. plans (as defined in Section 4(b)(4) of ERISA), while generally not subject to the fiduciary responsibility provisions of ERISA or the provisions of Section 4975 of the Code, may nevertheless be subject to Similar Laws. Fiduciaries of any such plans should consult with their counsel before acquiring our common units.

In considering an investment in our common units with any portion of the assets of an employee benefit plan, a fiduciary of the employee benefit plan should consider, among other things, whether the investment is in accordance with the documents and instruments governing the employee benefit plan and the applicable provisions of ERISA, the Code or any applicable Similar Law relating to the fiduciary’s duties to the employee benefit plan, including, without limitation:

(a) whether such investment is prudent under Section 404(a)(1)(B) of ERISA and any other applicable Similar Laws;

(b) whether in making such investment, the employee benefit plan will satisfy the diversification requirements of Section 404(a)(1) (C) of ERISA and any other applicable Similar Laws;

(c) whether making such an investment will comply with the delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws;

(d) whether the investment will constitute a “prohibited transaction” under Section 406 of ERISA or Section 4975 of the Code (please read the discussion under “—Prohibited Transaction Issues” below);

47

(e) whether in making such an investment in our common units, the employee benefit plan will be considered to hold, as plan assets, (i) only the investment in our common units or (ii) an undivided interest in our underlying assets (please read the discussion under “—Plan Asset Issues” below); and

(f) whether such investment will result in recognition of unrelated business taxable income by the employee benefit plan and, if so, the potential after-tax investment return (please read the discussion under “Material U.S. Federal Income Tax Consequences—Tax-Exempt Organizations and Other Investors”).

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit employee benefit plans (and certain IRAs that are not considered part of an employee benefit plan) from engaging in certain transactions involving “plan assets” with parties that are “parties in interest” under Section 406 ERISA or “disqualified persons” under Section 4975 of the Code with respect to the employee benefit plan or IRA, unless an exemption is applicable. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, a fiduciary of an ERISA Plan or IRA that engages in such a non-exempt prohibited transaction may be subject to excise taxes, penalties and liabilities under ERISA and the Code. Employee benefit plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA or Section 4975(g) (3) of the Code) and non-U.S. plans (as described in Section 4(b)(4) of ERISA) are not subject to the requirements of ERISA or Section 4975 of the Code but may be subject to similar prohibitions under other applicable Similar Laws.

Because of the foregoing, our common units may not be purchased or held by any person investing “plan assets” of any employee benefit plan, unless such purchase and holding will not constitute a non-exempt prohibited transaction under ERISA or the Code or similar violation of any applicable Similar Laws.

Plan Asset Issues

In connection with an investment in our common units with any portion of the assets of an employee benefit plan, in addition to considering whether the purchase of our common units is a prohibited transaction, a fiduciary of an employee benefit plan should consider whether such plan will, by investing in our common units, be deemed to own an undivided interest in our assets, with the result that our general partner also would be a fiduciary of such plan and our operations would be subject to the regulatory restrictions of ERISA, including its prohibited transaction rules, as well as the prohibited transaction rules of the Code and any other applicable Similar Laws. In addition, if our assets are deemed to be “plan assets” under ERISA, this would result, among other things, in (a) the application of the prudence and other fiduciary responsibility standards of ERISA to investments made by us, and (b) the possibility that certain transactions in which we seek to engage could constitute a “prohibited transaction” under the Code, ERISA and any other applicable Similar Laws.

The Department of Labor regulations, as modified by Section 3(42) of ERISA, provide guidance with respect to whether, in certain circumstances, the assets of an entity in which employee benefit plans acquire equity interests would be deemed “plan assets.” Under these regulations, an entity’s underlying assets generally would not be considered to be “plan assets” if, among other things:

(a) the equity interests acquired by the employee benefit plan are “publicly offered securities”—i.e., the equity interests are part of a class of securities that is widely held by 100 or more investors independent of the issuer and each other, are “freely transferable” (as defined in the applicable Department of Labor regulations), and are either part of a class of securities registered pursuant to certain provisions of the federal securities laws or sold to the plan as part of a public offering under certain conditions;

(b) the entity is an “operating company” —i.e., it is primarily engaged in the production or sale of a product or service other than the investment of capital, either directly or through a majority-owned subsidiary or subsidiaries, or it qualifies as a “venture capital operating company” or a “real estate operating company”; or

48

(c) there is no “significant” investment by “benefit plan investors” (as defined in Section 3(42) of ERISA), which is defined to mean that, immediately after the most recent acquisition by an employee benefit plan of any equity interest in the entity by such benefit plan investor, less than 25% of the total value of each class of equity interest (disregarding certain interests held by our general partner, its affiliates, and certain other persons who have discretionary authority or control with respect to the assets of the entity or provide investment advice for a fee with respect to such assets), is held by the employee benefit plans that are subject to part 4 of Title I of ERISA (which excludes governmental plans and non-electing church plans) and/or Section 4975 of the Code, IRAs and certain other employee benefit plans not subject to ERISA (such as electing church plans).

With respect to an investment in our common units, we believe that our assets should not be considered “plan assets” under these regulations because it is expected that the investment will satisfy the requirements in (a) and (b) above and may also satisfy the requirement in (c) above (although we do not monitor the level of investment by benefit plan investors as required for compliance with (c)). However, although we do not intend for our assets to be deemed “plan assets” under these regulations, there can be no, and we do not provide any, assurance regarding this issue to any investor.

The foregoing discussion of issues arising for employee benefit plan investments under ERISA, the Code and applicable Similar Laws is general in nature and is not intended to be all inclusive, and is based on laws in effect on the date of this prospectus. This discussion should not be construed as legal advice. Plan fiduciaries and other persons contemplating a purchase of our common units should consult with their own counsel regarding the potential applicability of and consequences of such purchase under ERISA, the Code and other Similar Laws in light of the complexity of these rules and the serious penalties, excise taxes and liabilities imposed on persons who engage in non-exempt prohibited transactions or other violations. Investors in our common units have exclusive responsibility for ensuring that their purchase of our common units complies with the fiduciary responsibility rules of ERISA and does not violate the prohibited transaction rules of ERISA or the Code or any similar provisions of Similar Laws. The sale of any common units by or to any employee benefit plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by such employee benefit plans generally or any particular employee benefit plan, or that such an investment is appropriate for such employee benefit plans generally or any particular employee benefit plan.

Representation

By purchase or acceptance of our common units or any interest therein, each purchaser and subsequent transferee of our common units will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire and hold our common units constitutes assets of any employee benefit plan or (ii) the purchase and holding of our common units by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable Similar Laws.

PLAN OF DISTRIBUTION

Under this prospectus and any accompanying prospectus supplement, we may sell our common units in and outside the United States (1) through one or more broker-dealers, (2) through underwriters, (3) through agents, (4) directly to investors, (5) through a combination of any of these methods of sale or (6) through any other methods permitted by applicable law. The prospectus supplement will set forth the following information:

• the terms of the offering;

• the names of any underwriters or agents;

• the name or names of any managing underwriter or underwriters;

• the purchase price of our common units;

• the net proceeds we will receive from the sale of the common units;

• any delayed delivery arrangements;

• any underwriting discounts, commissions and other items constituting underwriters’ compensation;

• the initial public offering price;

• any discounts or concessions allowed or reallowed or paid to dealers; and

• any commissions paid to agents.

We will fix a price of our common units at:

• market prices prevailing at the time of any sale under this registration statement;

• prices related to market prices; or

• negotiated prices.

We may change the price of the common units offered from time to time.

We will pay or allow distributors’ or sellers’ commissions that will not exceed those customary in the types of transactions involved. Broker-dealers may act as agents or may purchase securities as principal and thereafter resell the common units from time to time:

• in or through one or more transactions or distributions;

• on the New York Stock Exchange;

• in the over-the-counter market; or

• in private transactions.

Sale Through Underwriters or Dealers

If we use underwriters in the sale of our common units, the underwriters will acquire the common units for their own account. The underwriters may resell the common units from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the common units will be subject to certain conditions, and the underwriters will be obligated to purchase all of the offered common units if they purchase any of them. The underwriters may sell common units to or through dealers, and the dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or

50

commissions from the purchasers for whom they may act as agent. The underwriters may change from time to time the public offering price and any discounts, concessions or commissions allowed or reallowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the common units in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the common units sold for their account may be reclaimed by the syndicate if the offered common units are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered common units, which may be higher than the price that might otherwise prevail in the open market. If commenced, these activities may be discontinued at any time.

If we use dealers in the sale of securities, we may sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of these securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

Direct Sales and Sales Through Agents

We may sell the common units directly. In that event, no underwriters or agents would be involved. We may sell the common units directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those common units. We may use electronic media, including the Internet, to sell the common units directly.

We may also sell the common units through agents we designate from time to time. We will describe the terms of any such sales in the prospectus supplement. In the prospectus supplement, we will name any agent involved in the offer or sale of the common units, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

At-the-Market Offerings

To the extent that we make sales of the common units through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a sales agency financing agreement or other at-the-market offering arrangement between us and the underwriters or agents. If we engage in at-the-market sales of the common units pursuant to any such agreement, we will issue and sell our common units through one or more underwriters or agents, which may act on an agency basis or on a principal basis. During the term of any such agreement, we may sell our common units on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The agreement will provide that any common units sold will be sold at prices related to the then-prevailing market prices for our common units. Therefore, exact figures regarding proceeds that will be raised or commissions to be paid cannot be determined at this time. Pursuant to the terms of the agreement, we also may agree to sell, and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common units. The terms of each such agreement will be set forth in more detail in the applicable prospectus supplement.

Delayed Delivery Contracts or Forward Contracts

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from selected types of institutions to purchase the common units from us at the public offering price under delayed delivery contracts or forward contracts providing for payment or delivery on a specified date in the

51

future at prices determined as described in the prospectus supplement. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of such contracts.

General Information

We may have agreements with firms, agents, dealers and underwriters to indemnify them against civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the firms, agents, dealers or underwriters may be required to make. Such firms, agents, dealers and underwriters may be customers of, engage in transactions with or perform services for us in the ordinary course of their businesses.

Because the Financial Industry Regulatory Authority (“FINRA”) views our common units as interests in a direct participation program, any offering of common units under the registration statement of which this prospectus forms a part will be made in compliance with Rule 2310 of the FINRA Conduct Rules. Any compensation to be received by underwriters in connection with an offering of securities pursuant to this prospectus will not exceed 8% of the gross proceeds of such offering.
