The Company

Overview

We are a publicly traded Delaware limited liability company formed in October 2013. Our common units are traded on the New York Stock Exchange under the symbol "ENLC." Our assets consist of equity interests in ENLK. ENLK primarily focuses on providing midstream energy services, including:

•: gathering, compressing, treating, processing, transporting, storing, and selling natural gas;
•: fractionating, transporting, storing, and selling NGLs; and
•: gathering, transporting, stabilizing, storing, trans-loading, and selling crude oil and condensate, in addition to brine disposal services.

Our midstream energy asset network includes approximately 11,000 miles of pipelines, 20 natural gas processing plants with approximately 4.9 Bcf/d of processing capacity, seven fractionators with approximately 280,000 Bbls/d of fractionation capacity, barge and rail terminals, product storage facilities, purchasing and marketing capabilities, brine disposal wells, a crude oil trucking fleet, and equity investments in certain joint ventures. Our operations are based in the United States, and our sales are derived primarily from domestic customers. We have five reportable segments as of January 1, 2019:

•: Oklahoma Segment. The Oklahoma segment includes our natural gas gathering, processing, and transmission activities and our crude oil operations in the Cana-Woodford, Arkoma-Woodford, Northern Oklahoma Woodford, STACK, and CNOW shale areas;

•: Permian Segment. The Permian segment includes our natural gas gathering, processing, and transmission activities and our crude oil operations in the Permian Basin;
•: Louisiana Segment. The Louisiana segment includes our natural gas pipelines, natural gas processing plants, storage facilities, fractionation facilities, and NGL assets located in Louisiana and our crude oil operations in the Ohio River Valley;
•: North Texas Segment. The North Texas segment includes our natural gas gathering, processing, and transmission operations in North Texas; and
•: Corporate Segment. The Corporate segment includes our unconsolidated affiliate investments in Cedar Cove Midstream LLC in Oklahoma, our ownership interest in Gulf Coast Fractionators in South Texas, and our general corporate assets and expenses.

We manage our operations by focusing on gross operating margin because our business is generally to gather, process, transport, or market natural gas, NGLs, crude oil, and condensate using our assets for a fee. We earn our fees through various fee-based contractual arrangements, which include stated fee-only contract arrangements or arrangements with fee-based components where we purchase and resell commodities in connection with providing the related service and earn a net margin as our fee. We earn our net margin under our purchase and resell contract arrangements primarily as a result of stated service-related fees that are deducted from the price of the commodity purchase. While our transactions vary in form, the essential element of most of our transactions is the use of our assets to transport a product or provide a processed product to an end-user or marketer at the tailgate of the plant, pipeline, or barge, truck, or rail terminal.

Our Business Strategies

Our primary business objective is to provide cash flow stability in our business while growing prudently and profitably. We intend to accomplish this objective by executing the following strategies:

•: Execute in our core growth areas. We believe our assets are positioned in some of the most economically advantageous basins in the U.S., as well as key demand centers with growing end-use customers. We expect to grow certain of our systems organically over time by meeting our customers' midstream service needs that result from their drilling activity in our areas of operation or growth in supply needs. We continually evaluate economically attractive organic expansion opportunities in our areas of operation that allow us to leverage our existing infrastructure, operating expertise, and customer relationships by constructing and expanding systems to meet new or increased demand for our services.
•: Maintain a strong financial position. We believe that maintaining a conservative and balanced capital structure, appropriate leverage, and other key financial metrics will afford us better access to the capital markets at a competitive cost of capital. We also believe a strong financial position provides us the opportunity to grow our business in a prudent manner throughout the cycles in our industry.
•: Maintain stable cash flows supported by long-term, fee-based contracts. We will seek to generate cash flows pursuant to long-term, firm contracts with creditworthy customers. We will continue to pursue opportunities to increase the fee-based components of our contract portfolio to minimize our direct commodity price exposure.

Our Competitive Strengths

We believe that we are well-positioned to execute our strategies and to achieve our primary business objective due to the following competitive strengths:

•: Strategically-located assets. The majority of our assets are strategically located in economically advantageous regions with the potential for increasing throughput volume and cash flow generation. Our asset portfolio includes gathering, transmission, fractionation, and processing systems that are located in the areas in which producer activity is focused on crude oil, condensate, and NGLs, as well as natural gas. We have established platforms in Texas, Oklahoma, and Louisiana, and we are focused on growing our operations in Central Oklahoma, the Permian Basin, and southern Louisiana through organic development and acquisitions.
•: Stable cash flows. Approximately 88.3% of our gross operating margin for the year ended December 31, 2018 was generated from fee-based contract arrangements with minimal direct commodity price exposure. In addition, our cash flows are generated across a variety of products, services, and geographic locations and through transactions with a strong portfolio of customers with investment-grade credit ratings. We have approximately 10 years remaining on fixed-fee gathering and processing agreements with a subsidiary of Devon pursuant to which we provide gathering, treating, compression, dehydration, stabilization, processing, and fractionation services, as applicable, for natural gas delivered by Devon to our gathering and processing systems in the Barnett and Cana-Woodford Shales. These agreements provide us with dedication of all of the natural gas owned or controlled by Devon and produced from or attributable to existing and future wells located on certain oil, natural gas, and mineral leases covering lands within the acreage dedications, excluding properties previously dedicated to other natural gas gathering systems not owned and operated by Devon. Additionally, our EnLink Oklahoma Gas Processing, LP ("EOGP") assets are supported by Devon with acreage dedications and MVCs for gathering and processing on Devon's STACK acreage through the end of 2020. We will continue to focus on contract structures that reduce volatility and support long-term stability of cash flows.
•: Integrated midstream services. We span the energy value chain by providing natural gas, NGL, crude oil, and condensate services across a diverse customer base. These services include gathering, compressing, treating, processing, transporting, storing, and selling natural gas, fractionating, transporting, storing, and selling NGLs, and gathering, transporting, stabilizing, storing, trans-loading, and selling crude oil and condensate. We believe our ability to provide all of these services gives us an advantage in competing for new opportunities because we can provide substantially all services that producers, marketers, and others require to move natural gas, NGLs, crude oil, and condensate from the wellhead to the market on a cost-effective basis.
•: Experienced management team. Our management team has deep experience in the energy industry and has a proven track record of creating value through the development, acquisition, optimization, and integration of midstream assets. We believe this team provides us with a strong foundation for evaluating growth opportunities and operating our assets in a safe, reliable, and efficient manner.

Recent Developments

Simplification of the Corporate Structure. On October 21, 2018, ENLC, the managing member of ENLC, ENLK, the general partner of ENLK, and NOLA Merger Sub, LLC ("NOLA Merger Sub") entered into the Agreement and Plan of Merger pursuant to which, on January 25, 2019, NOLA Merger Sub merged with and into ENLK (the "Merger"), with ENLK continuing as the surviving entity and as a subsidiary of ENLC.

Transfer of EOGP interest. On January 31, 2019, ENLC transferred its 16.1% limited partner interest in EOGP to the Operating Partnership.

Strategic Partner Update. On July 18, 2018, subsidiaries of Devon closed a transaction to sell all of their equity interests in ENLC, ENLK, and ENLC's managing member to affiliates of Global Infrastructure Management, LLC ("GIP"). Through this transaction, GIP acquired control of (i) ENLC, (ii) ENLC's managing member, and (iii) ENLK, as a result of ENLC's ownership of the general partner of ENLK.

Cajun-Sibon Pipeline. In 2018, we commenced an expansion of our Cajun-Sibon NGL pipeline capacity, which connects the Mont Belvieu NGL hub to our fractionation facilities in Louisiana. This is the third phase of our Cajun-Sibon system referred to as Cajun Sibon III, which will increase throughput capacity from 130,000 bbls/d to 185,000 bbls/d. We expect Cajun-Sibon III to be operational during the second quarter of 2019.

Avenger Crude Oil Gathering System. During 2018, we constructed a new crude oil gathering system in the northern Delaware Basin called Avenger. Avenger is supported by a long-term contract with Devon on dedicated acreage in their Todd and Potato Basin development areas in Eddy and Lea counties in New Mexico. We commenced initial operations on Avenger during the third quarter of 2018 and expect to begin full-service operations during the third quarter of 2019.

Central Oklahoma Plants. In December 2017, we commenced construction on our Thunderbird Plant to expand our Central Oklahoma processing capacity by an additional 200 MMcf/d. We expect to begin operations on the Thunderbird Plant during the second quarter of 2019.

Central Oklahoma Crude Oil Gathering Systems. In late March 2018, we completed construction of the first phase of Black Coyote. Black Coyote expands our operations in the core of the STACK play in Central Oklahoma and was built primarily to service acreage dedicated from Devon, which is the anchor customer on the system. In addition, we further expanded our crude oil gathering operations in the STACK through the construction of Redbud, which is supported by a contract with Marathon Oil Company. We commenced initial operations on Redbud during the third quarter of 2018.

Lobo Natural Gas Gathering and Processing Facilities. During the second quarter of 2018, we completed construction of an expansion to our Lobo II cryogenic gas processing plant, which brought total operational processing capacity at our Lobo facilities to 175 MMcf/d. We further expanded our natural gas processing capacity at our Lobo facilities through the construction of the Lobo III cryogenic gas processing plant, which was completed during the fourth quarter of 2018. Lobo III provides an additional 100 MMcf/d of operational capacity.

Principal Executive Offices and Internet Address

Our principal executive offices are located at 1722 Routh Street, Suite 1300, Dallas, Texas 75201 and our telephone number is (214) 953-9500. Our website is located at www.enlink.com. We make available our periodic reports and other information filed with or furnished to the Securities and Exchange Commission, the "SEC" or the "Commission," free of charge, through our website, as soon as reasonably practicable after those reports and other information are electronically filed with or furnished to the Commission. The information on our website is not part of this prospectus supplement or the accompanying base prospectus, and you should rely only on information contained or incorporated by reference in this prospectus supplement or the accompanying base prospectus when making a decision as to whether or not to invest in our notes.

The following diagram depicts our organization and approximate ownership as of February 1, 2019, after the close of the Merger and the transfer of the 16.1% limited partner interest in EOGP from us to the Operating Partnership:

(1): Subsequent to the closing of the Merger, ENLK's Series B Cumulative Convertible Preferred Units ("Series B Preferred Units") are exchangeable into ENLC common units on a

1-for-1.15 basis, subject to certain adjustments. Upon the exchange of any Series B Preferred Units into ENLC common units, an equal number of the ENLC Class C Common Units will be canceled. As of February 1, 2019, the outstanding ENLC Class C Common Units, which are non-economic interests issued immediately following the Merger to the holder of the Series B Preferred Units to provide it with certain voting rights at ENLC, represent a 10.8% membership interest in ENLC.

(2): All ENLK common units are held by ENLC. The Series B Preferred Units are entitled to vote, on a one-for-one basis (subject to certain adjustments) as a single class with ENLC, on all matters that require approval of the ENLK unitholders.
(3): ENLK's Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units ("Series C Preferred Units") are perpetual preferred units that are not convertible into other equity interests, and therefore are not factored into the ENLK ownership calculations for the limited partner and general partner ownership percentages presented.

Governing Law		The indenture governing the notes and the notes will be governed by, and construed in accordance with, the laws of the State of New York.

An investment in the notes involves risks. You should consider carefully the following risk factors and the risk factors set forth beginning on page 1 of the accompanying base prospectus and in our Annual Report on Form 10-K for the year ended December 31, 2018, together with all of the other information included in, or incorporated by reference into, this prospectus supplement and the accompanying base prospectus when evaluating an investment in the notes.

Our significant indebtedness, and any future indebtedness, as well as the restrictions in our debt agreements may adversely affect our future financial and operating flexibility and our ability to service the notes.

As of December 31, 2018, after giving effect to this offering and the application of the net proceeds as described in "Use of Proceeds," our consolidated indebtedness would have been approximately $ billion, and we would have been able to incur approximately $ billion of additional indebtedness under our revolving credit facility, after giving effect to certain covenants therein restricting our ability to incur additional indebtedness. Our substantial indebtedness and the additional debt we may incur in the future for potential acquisitions or operating activities may adversely affect our liquidity and therefore our ability to make interest payments on the notes.

Among other things, our significant indebtedness may be viewed negatively by credit rating agencies, which could result in increased costs for us to access the capital markets. Any future downgrade of the debt issued by us or our subsidiaries, including ENLK's existing senior notes, could significantly increase our capital costs or adversely affect our ability to raise capital in the future.

Debt service obligations and restrictive covenants in our revolving credit facility, our term loan, the indenture governing ENLK's existing senior notes, and the indenture governing the notes may adversely affect our ability to finance future operations, pursue acquisitions, and fund other capital needs. In addition, this leverage may make our results of operations more susceptible to adverse economic or operating conditions by limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate and may place us at a competitive disadvantage as compared to our competitors that have less debt.

The indenture governing the notes will permit us and ENLK to incur additional debt, which would be equal in right of payment to the notes and the guarantee. If we incur any additional indebtedness, including trade payables, that ranks equally with the notes, the holders of that debt would be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization, dissolution, or other winding up of us. This may have the effect of reducing the amount of proceeds paid to you. If new debt is added to our current debt levels, the related risks that we now face could intensify.

The notes and the guarantee will be our and ENLK's senior unsecured obligations and as a result, will be effectively junior to our or ENLK's future secured indebtedness, to the extent of the value of the collateral securing such indebtedness, and structurally subordinated to the indebtedness and other liabilities of our subsidiaries, other than ENLK and any subsidiaries that may guarantee the notes in the future.

The notes and ENLK's guarantee will be our and ENLK's senior unsecured obligations and will rank equally in right of payment with all of our and ENLK's other existing and future senior indebtedness, and will be structurally subordinated to the claims of all creditors, including trade creditors and tort claimants, of our subsidiaries that do not guarantee the notes. In the event of the liquidation, dissolution, reorganization, bankruptcy, or similar proceeding of the business of a subsidiary that is not a guarantor, creditors of that subsidiary, including trade creditors, would generally have the right to be paid in full before any distribution is made to us or the holders of the notes. Accordingly, there may not be sufficient funds remaining to pay amounts due on all or any of the notes. As of December 31, 2018, our non-guarantor subsidiaries had approximately $2.5 million of indebtedness outstanding, consisting of capital leases. The indentures governing ENLK's existing senior notes do not prohibit, and the indenture governing the notes will not prohibit, such subsidiaries from incurring indebtedness in the future.

In addition, because the notes and the guarantee are, and any future guarantees of the notes will be, unsecured, holders of any secured indebtedness of ours or our subsidiaries would have claims with respect to the assets constituting collateral for such indebtedness that are senior to the claims of the holders of the notes. Currently, neither we nor any of our subsidiaries has any secured indebtedness. Although the indentures governing ENLK's existing senior notes place, and the indenture governing the notes will place, some limitations on our and ENLK's ability to create liens securing indebtedness, there will be significant exceptions to these limitations that would allow us or ENLK to secure significant amounts of indebtedness without equally and ratably securing the notes. If we or our subsidiaries incur secured indebtedness and such indebtedness is accelerated or we become subject to bankruptcy, liquidation, or reorganization proceedings, our and our subsidiaries' assets would be used to satisfy obligations with respect to the indebtedness secured thereby before any payment could be made on the notes. Consequently, any such secured indebtedness would effectively be senior to the notes and ENLK's guarantee, as well as any future guarantees of the notes, to the extent of the value of the collateral securing such secured indebtedness. In that event, you may not be able to recover all the principal or interest you are due under the notes.

ENLK's guarantee and any future subsidiary guarantees could be deemed fraudulent conveyances under certain circumstances, and in such event a court may try to subordinate or void the subsidiary guarantees.

Initially, only ENLK will guarantee the notes, although in the future one or more of our other subsidiaries may also guarantee the notes. Under the federal bankruptcy laws and comparable provisions of state fraudulent transfer laws, a subsidiary guarantee could be voided, or claims in respect of a subsidiary guarantee could be subordinated to all other debts of that subsidiary guarantor if, among other things, the subsidiary guarantor, at the time it incurred the

indebtedness evidenced by its subsidiary guarantee received less than reasonably equivalent value or fair consideration for the incurrence of such subsidiary guarantee; and

In addition, any payment by that subsidiary guarantor pursuant to its subsidiary guarantee could be voided and required to be returned to the subsidiary guarantor, or to a fund for the benefit of the creditors of the subsidiary guarantor. The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, a subsidiary guarantor would be considered insolvent if:

The indenture governing the notes will include only limited covenants and these limited covenants may not protect your investment.

The indenture governing the notes will also permit us and our subsidiaries to incur additional indebtedness, including secured indebtedness, that could effectively rank senior to the notes, and to engage in leaseback arrangements, subject to certain limitations. Any of these actions could adversely affect our ability to make principal and interest payments on the notes.

We have a holding company structure in which our subsidiaries conduct our operations and own our operating assets, and our cash flow consists almost exclusively of cash flows from ENLK.

We are a holding company, and our subsidiaries conduct all of our operations and own all of our operating assets. Currently, our only cash-generating asset is our partnership interest in ENLK. As a result, our ability to make required payments on the notes depends on the performance of our subsidiaries and their ability to distribute funds to us. The ability of our subsidiaries to make distributions to us may be restricted by, among other things, debt agreements, ENLK's distribution requirements with respect to the Series B Preferred Units and the Series C Preferred Units, and applicable state partnership laws and other laws and regulations. In addition, distributions made by our subsidiaries that are held in a joint venture are reduced by amounts that such subsidiaries are obligated to distribute to our joint venture partners. If our subsidiaries are prevented from distributing funds to us, we may be unable to pay all the principal and interest on the notes when due.

Your ability to transfer the notes at a time or price you desire may be limited by the absence of an active trading market, which may not develop.

Although we have registered the offer and sale of the notes under the Securities Act of 1933, as amended, we do not intend to apply for the listing of the notes on any securities exchange or for the quotation of the notes on any automated dealer quotation system. In addition, although the underwriters have informed us that they intend to make a market in the notes of each series, as permitted by applicable laws and regulations, they are not obligated to make markets in the notes, and they may discontinue their market-making activities at any time without notice. Active markets for the notes may not develop or, if developed, may not continue. In the absence of active trading markets, you may not be able to transfer the notes within the time or at the prices you desire.

An increase in market interest rates could result in a decrease in the market value of the notes.

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the notes. In general, as market interest rates rise, debt securities bearing interest at fixed rates of interest decline in value. Consequently, if you purchase notes bearing interest at fixed rates of interest and market interest rates increase, the market values of those notes may decline. We cannot predict the future level of market interest rates.

We may not be able to generate sufficient cash to service all of our indebtedness, including the notes, ENLK's existing notes and our indebtedness under our revolving credit facility and term loan, and we may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business, and other factors beyond our control. We cannot assure you that we will maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, or operations, seek additional capital, or restructure or refinance our indebtedness, including the notes. We cannot assure you that we would be able to take any of these actions, that these actions would be successful and would permit us to meet our scheduled debt service obligations or that these actions would be permitted under the terms of our existing or future debt agreements, including our credit agreement and term loan, the indentures governing ENLK's existing notes and the indenture that will govern the notes. For example, our revolving credit facility contains restrictions on our ability to dispose of assets. We may not be able to consummate asset dispositions, and any proceeds may not be adequate to meet any debt service obligations then due. See "Description of Notes."

The credit and risk profile of our managing member and its owner could adversely affect our credit ratings and profile.

The credit and business risk profiles of our managing member and its indirect owner, GIP, may be factors in credit evaluations of us due to the control of our managing member and the significant influence over our business activities, including our cash distributions, acquisition strategy, and business risk profile.

We expect to receive net proceeds from this offering of approximately $ million after deducting the underwriting discounts and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering to repay outstanding borrowings under our revolving credit facility, including borrowings incurred to repay the ENLK 2019 Notes (as defined below) at maturity, and for general limited liability company purposes.

As of April 1, 2019, we had $610.0 million in borrowings and $6.2 million in outstanding letters of credit under our $1.75 billion unsecured revolving credit facility (which includes a $500.0 million letter of credit subfacility) at a weighted average interest rate of 4.4%. Our revolving credit facility matures in January 2024 unless we request, and the requisite lenders agree, to extend it pursuant to its terms. Borrowings under our revolving credit facility were used to repay certain amounts under our prior revolving credit facility and ENLK's prior revolving credit facility, each of which was terminated on January 25, 2019, as well as to fund capital expenditures and for general limited liability company purposes. In addition, on April 1, 2019, we used borrowings under our revolving credit facility to repay at maturity the $400.0 million outstanding aggregate principal amount of ENLK's 2.70% senior notes due 2019 (the "ENLK 2019 Notes").

Affiliates of certain of the underwriters are lenders under our revolving credit facility that we expect to reduce using the net proceeds from this offering and, accordingly, such underwriters and affiliates will receive a portion of the net proceeds from this offering. See "Underwriting (Conflicts of Interest)."

At the closing of this offering, we will enter into a base indenture between us and Wells Fargo Bank, National Association, as trustee, pursuant to which we may issue multiple series of debt securities from time to time. We will issue the notes under such base indenture, as supplemented by a supplemental indenture among us, EnLink Midstream Partners, LP, and Wells Fargo Bank, National Association, as trustee, setting forth the specific terms of the notes. In this description, when we refer to the "indenture," we mean the base indenture as so amended and supplemented by the supplemental indenture. This description is a summary of the material provisions of the notes and the indenture. This description does not restate those agreements and instruments in their entirety. You should refer to the notes and the indenture, forms of which are available as set forth below under "Available Information," for a complete description of our obligations and your rights.

The following description of the particular terms of the notes supplements the general description of the debt securities included in the accompanying base prospectus under the caption "Description of the Debt Securities." The notes offered hereby will be a series of senior debt securities issued by us as described herein and therein. You should review this "Description of Notes" together with the "Description of the Debt Securities" included in the accompanying base prospectus. To the extent that this "Description of Notes" is inconsistent with the "Description of the Debt Securities" in the accompanying base prospectus, this "Description of Notes" will control and replace the inconsistent "Description of the Debt Securities" in the accompanying base prospectus.

You can find the definitions of various terms used in this description under "— Certain Definitions" below. In this description, the terms "ENLC," "we," "us," and "our" refer only to EnLink Midstream, LLC and not to any of its Subsidiaries, and the term "ENLK" refers only to EnLink Midstream Partners, LP and not to any of its Subsidiaries.

The notes constitute a series of debt securities under the indenture. The indenture does not limit the amount of debt securities we may issue under the indenture from time to time in one or more series. We may in the future issue additional debt securities under the indenture in addition to the notes as described below under "— Further Issuances."

Interest on the notes will accrue from and including April , 2019 or from and including the most recent interest payment date to which interest has been paid or provided for. We will pay interest on the notes in cash semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2019. We will make interest payments on the notes to the persons in whose names the notes are registered at the close of business on May 15 and November 15, as applicable, before the next interest payment date.

Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any interest payment date falls on a day that is not a business day, the payment will be made on the next business day, and no interest will accrue on the amount of interest due on that interest payment date for the period from and after the interest payment date to the date of payment.

The trustee will initially act as paying agent and registrar for the notes. We may change the paying agent or registrar without prior notice to the holders of the notes, and we or any of our Subsidiaries may act as paying agent or registrar; provided, however, that we will be required to maintain at all times an office or agency in The City of New York (which may be an office of the trustee or an affiliate of the trustee or the registrar or a co-registrar for the notes) where the notes may be presented for payment and where notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon us in respect of the notes and the indenture may be served. We may also from time to time designate one or more additional offices or agencies where the notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations.

We may from time to time, without notice to or the consent of the holders of the notes, create and issue additional notes having the same terms as any of the series of notes offered by this prospectus supplement and accompanying base prospectus, except for the issue date, public offering price, and in some cases, the first interest payment date. Additional notes issued in this manner will form a single series with the previously issued and outstanding notes of such series.

Prior to March 1, 2029 (three months prior to the maturity date of the notes) (the "Par Call Date"), the notes will be redeemable, at our option, at any time in whole, or from time to time in part, at a price equal to the greater of:

plus, in either case, accrued and unpaid interest to, but excluding, the redemption date.

At any time on or after the Par Call Date, the notes will be redeemable in whole or in part, at our option, at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

For purposes of determining the redemption price, the following definitions are applicable:

"Comparable Treasury Issue" means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the notes to be redeemed (calculated as if the maturity date of the notes was the Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such notes (calculated as if the maturity date of the notes was the Par Call Date).

"Comparable Treasury Price" means, with respect to any redemption date for notes, (1) the average of four Reference Treasury Dealer Quotations for such redemption date after excluding the highest and lowest of all of the Reference Treasury Dealer Quotations or (2) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

"Primary Treasury Dealer" means a U.S. government securities dealer in the United States.

"Reference Treasury Dealer" means each of (i) RBC Capital Markets, LLC, BMO Capital Markets Corp., and Wells Fargo Securities, LLC and their respective successors that are Primary Treasury Dealers and (ii) a Primary Treasury Dealer selected by SunTrust Robinson Humphrey, Inc. or it successor, provided that, if at any time any of the foregoing is not a Primary Treasury Dealer, ENLC will substitute therefor another Primary Treasury Dealer.

"Reference Treasury Dealer Quotation" means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding the redemption date.

"Treasury Rate" means, with respect to any redemption date, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate will be calculated on the third business day preceding any redemption date.

If fewer than all of the notes are to be redeemed at any time, such notes will be selected for redemption not more than 60 days prior to the redemption date and such selection will be made by the trustee on a pro rata basis, by lot or by such other method as the trustee deems appropriate (or, in the case of notes represented by a note in global form, by such method as The Depository Trust Company ("DTC") may require); provided, that no partial redemption of any note will occur if such redemption would reduce the principal amount of such note to less than

$2,000. Notices of redemption with respect to the notes will be sent at least 15 but not more than 60 days before the redemption date to each holder of notes to be redeemed.

If any note is to be redeemed in part only, the notice of redemption that relates to such note will state the portion of the principal amount thereof to be redeemed. A new note in principal amount equal to the unredeemed portion thereof will be issued in the name of the holder thereof upon cancellation of the original note. Notes called for redemption will become due on the date fixed for redemption. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the notes or portions of the notes called for redemption.

The notes initially will be guaranteed by our subsidiary, ENLK. None of our other Subsidiaries will guarantee the notes upon their issuance. However, if at any time following the issuance of the notes, any other Subsidiary of ENLC becomes a guarantor or co-obligor of the Credit Agreement or the Term Loan, then ENLC will cause such Subsidiary to promptly execute and deliver to the trustee a supplemental indenture in a form satisfactory to the trustee pursuant to which such Subsidiary guarantees ENLC's obligations with respect to the notes on the terms provided for in the indenture.

The guarantee of ENLK and any other Subsidiary Guarantor may be released under certain circumstances. If we exercise our legal or covenant defeasance option with respect to the notes as described below under "— Defeasance and Discharge," then ENLK and any other Subsidiary Guarantor will be released. Further, if no default has occurred and is continuing under the indenture, and to the extent not otherwise prohibited by the indenture, any Subsidiary Guarantor will be unconditionally released and discharged from its guarantee:

If at any time following any release of ENLK or any other Subsidiary Guarantor from its guarantee of the notes pursuant to the third bullet point in the preceding paragraph, the Subsidiary Guarantor again becomes a guarantor or co-obligor of the Credit Agreement or the Term Loan, then ENLC will cause the Subsidiary Guarantor to again guarantee the notes in accordance with the indenture.

The notes will be unsecured, unless we are required to secure them pursuant to the limitations on liens covenant described below under "— Certain Covenants — Limitations on Liens." The notes will also be the unsubordinated obligations of ENLC and will rank equally with

all other existing and future unsubordinated indebtedness of ENLC. The guarantee of the notes by ENLK and any guarantee of the notes by any other Subsidiary Guarantor will be an unsecured and unsubordinated obligation of ENLK or the applicable Subsidiary Guarantor and will rank equally with all other existing and future unsubordinated indebtedness of ENLK (including its outstanding senior notes and its guarantee of the Credit Agreement and the Term Loan) and the applicable Subsidiary Guarantor. The notes and each guarantee will effectively rank junior to any future indebtedness of ENLC or any Subsidiary Guarantor that is both secured and unsubordinated to the extent of the value of the assets securing such indebtedness, and the notes will structurally rank junior to all indebtedness and other liabilities of ENLC's existing and future Subsidiaries that are not Subsidiary Guarantors.

As of December 31, 2018, after giving effect to this offering of the notes and the application of the net proceeds therefrom as described in "Use of Proceeds," ENLC, excluding its Subsidiaries, would have had $ billion of indebtedness outstanding, all of which would have been unsecured, unsubordinated indebtedness, consisting entirely of the notes and borrowings under the Credit Agreement and the Term Loan. Initially, none of ENLC's Subsidiaries other than ENLK will guarantee the notes. As of December 31, 2018, after giving effect to this offering of the notes and the application of the net proceeds therefrom as described in "Use of Proceeds," ENLK, excluding its Subsidiaries, would have had $ billion of indebtedness outstanding, all of which was unsecured, unsubordinated indebtedness, consisting entirely of its outstanding senior notes and its guarantee of the Credit Agreement and the Term Loan. As of December 31, 2018, the Subsidiaries of ENLC other than ENLK had approximately $2.5 million of indebtedness outstanding, consisting of capital leases.

We may at any time and from time to time repurchase notes in the open market or otherwise, in each case without any restriction under the indenture. We are not required to make any mandatory redemption or sinking fund payments with respect to the notes.

Except as set forth below, neither ENLC nor any of its Subsidiaries will be restricted by the indenture from incurring any type of indebtedness or other obligation, from paying dividends or making distributions on its limited liability company or other equity interests or from purchasing or redeeming its limited liability company or other equity interests. The indenture will not require the maintenance of any financial ratios or specified levels of net worth or liquidity. In addition, the indenture will not contain any provisions that would require ENLC to repurchase or redeem or otherwise modify the terms of the notes upon a change in control or other events involving ENLC that could adversely affect the creditworthiness of ENLC.

Limitations on Liens. ENLC will not, nor will it permit any of its Principal Subsidiaries to, create, assume, incur or suffer to exist any mortgage, lien, security interest, pledge, charge or other encumbrance ("liens") upon any Principal Property or upon any capital stock of any Principal Subsidiary, whether owned on the date of the supplemental indenture creating the notes or thereafter acquired, to secure any Indebtedness of ENLC or any other Person (other than the notes), without in any such case making effective provisions whereby all of the outstanding notes

are secured equally and ratably with, or prior to, such Indebtedness so long as such Indebtedness is so secured.

Notwithstanding the foregoing, under the indenture, ENLC may, and may permit any of its Principal Subsidiaries to, create, assume, incur, or suffer to exist without securing the notes (a) any Permitted Lien, (b) any lien upon any Principal Property or capital stock of a Principal Subsidiary to secure Indebtedness of ENLC or any other Person, provided that the aggregate principal amount of all Indebtedness then outstanding secured by such lien and all similar liens under this clause (b), together with all Attributable Indebtedness from Sale-Leaseback Transactions (excluding Sale-Leaseback Transactions permitted by clauses (1) through (4), inclusive, of the first paragraph of the restriction on sale-leasebacks covenant described below), does not exceed 15% of Consolidated Net Tangible Assets or (c) any lien upon (i) any Principal Property that was not owned by ENLC or any of its Subsidiaries on the date of the supplemental indenture creating the notes or (ii) the capital stock of any Principal Subsidiary that owns no Principal Property that was owned by ENLC or any of its Subsidiaries on the date of the supplemental indenture creating the notes, in each case owned by a Subsidiary of ENLC (an "Excluded Subsidiary") that (A) is not, and is not required to be, a Subsidiary Guarantor and (B) has not granted any liens on any of its property securing Indebtedness with recourse to ENLC or any Subsidiary of ENLC other than such Excluded Subsidiary or any other Excluded Subsidiary.

Restriction on Sale-Leasebacks. ENLC will not, and will not permit any Principal Subsidiary to, engage in the sale or transfer by ENLC or any of its Principal Subsidiaries of any Principal Property to a Person (other than ENLC or a Principal Subsidiary) and the taking back by ENLC or any Principal Subsidiary, as the case may be, of a lease of such Principal Property (a "Sale-Leaseback Transaction"), unless:

Notwithstanding the foregoing, ENLC may, and may permit any Principal Subsidiary to, effect any Sale-Leaseback Transaction that is not excepted by clauses (1) through (4), inclusive, of the

preceding paragraph provided that the Attributable Indebtedness from such Sale-Leaseback Transaction, together with the aggregate principal amount of outstanding Indebtedness (other than the notes) secured by liens permitted by clause (b) of the second paragraph of the restriction on liens covenant described above, does not exceed 15% of Consolidated Net Tangible Assets.

Merger, Consolidation or Sale of Assets. ENLC shall not consolidate with or merge into any Person or sell, lease, convey, transfer, or otherwise dispose of all or substantially all of its assets to any Person unless:

The successor will be substituted for ENLC in the indenture with the same effect as if it had been an original party to the indenture. Thereafter, the successor may exercise the rights and powers of ENLC under the indenture. If ENLC conveys or transfers all or substantially all of its assets, it will be released from all liabilities and obligations under the indenture and under the notes except that no such release will occur in the case of a lease of all or substantially all of its assets.

The defeasance provisions of the indenture described in the accompanying base prospectus will apply to the notes. See "Description of the Debt Securities — Defeasance" in the accompanying base prospectus.

The indenture will also be subject to discharge with respect to the notes as described in the accompanying base prospectus under "Description of the Debt Securities — Satisfaction and Discharge."

The indenture will contain certain limitations on the right of the trustee, should it become our creditor, to obtain payment of claims in certain cases, or to realize for its own account on certain property received in respect of any such claim as security or otherwise. The trustee is permitted to engage in certain other transactions. However, if it acquires any conflicting interest within the meaning of the Trust Indenture Act after a default has occurred and is continuing, it must eliminate the conflict within 90 days, apply to the SEC for permission to continue as trustee or resign.

If an Event of Default occurs and is not cured or waived, the trustee is required to exercise such of the rights and powers vested in it by the indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. Subject to such provisions, the trustee will not be under any obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of notes unless they have offered to the trustee security or indemnity satisfactory to it against the costs, expenses, and liabilities it may incur.

Wells Fargo Bank, National Association will be the trustee under the indenture and the registrar and paying agent with regard to the notes. The trustee and its affiliates maintain commercial banking and other relationships with ENLC and its Subsidiaries.

The indenture and the notes will be governed by, and will be construed in accordance with, the laws of the State of New York.

We have obtained the information in this section concerning The Depository Trust Company ("DTC") and its book-entry systems and procedures from DTC, and we take no responsibility for the accuracy of this information. In addition, the description in this section reflects our understanding of the rules and procedures of DTC as they are currently in effect. DTC could change its rules and procedures at any time.

The notes will initially be represented by one or more fully registered global notes. Each such global note will be deposited with, or on behalf of, DTC or any successor thereto and registered in the name of Cede & Co. (DTC's nominee). You may hold your interests in the global notes through DTC either as a participant in DTC or indirectly through organizations that are participants in DTC.

So long as DTC or its nominee is the registered owner of the global securities representing the notes, DTC or such nominee will be considered the sole owner and holder of the notes for all purposes of the notes and the indenture. Except as provided below, owners of beneficial interests in the notes will not be entitled to have the notes registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered the

owners or holders of the notes under the indenture, including for purposes of receiving any reports delivered by us or the trustee pursuant to the indenture. Accordingly, each person owning a beneficial interest in a note must rely on the procedures of DTC or its nominee and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of notes.

The Depository Trust Company. DTC will act as securities depositary for the notes. The notes will be issued as fully registered notes registered in the name of Cede & Co. DTC has advised us as follows: DTC is

DTC holds securities that its direct participants deposit with DTC. DTC facilitates the settlement among direct participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in direct participants' accounts, thereby eliminating the need for physical movement of securities certificates.

Direct participants of DTC include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations, and certain other organizations. DTC is owned by a number of its direct participants. Access to the DTC system is also available to securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

If you are not a direct participant or an indirect participant and you wish to purchase, sell, or otherwise transfer ownership of, or other interests in, notes, you must do so through a direct participant or an indirect participant. DTC agrees with and represents to DTC participants that it will administer its book-entry system in accordance with its rules and by-laws and requirements of law. The SEC has on file a set of the rules applicable to DTC and its direct participants.

Purchases of notes under DTC's system must be made by or through direct participants, who will receive a credit for the notes on DTC's records. The ownership interest of each beneficial owner is in turn to be recorded on the records of direct participants and indirect participants. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct participants or indirect participants through which such beneficial owners entered into the transaction. Transfers of ownership interests in the notes are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the notes, except in the event that use of the book-entry system for the notes is discontinued.

To facilitate subsequent transfers, all notes deposited by direct participants with DTC are registered in the name of DTC's nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of notes with DTC and their registration in the name of Cede & Co. do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes. DTC's records reflect only the identity of the direct participants to whose accounts such notes are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Book-Entry Format. Under the book-entry format, the trustee will pay interest or principal payments to Cede & Co., as nominee of DTC. DTC will forward the payment to the direct participants, who will then forward the payment to the indirect participants or to you as the beneficial owner. You may experience some delay in receiving your payments under this system. Neither we, the trustee under the indenture nor any paying agent has any direct responsibility or liability for the payment of principal or interest on the notes to owners of beneficial interests in the notes.

DTC is required to make book-entry transfers on behalf of its direct participants and is required to receive and transmit payments of principal, premium, if any, and interest on the notes. Any direct participant or indirect participant with which you have an account is similarly required to make book-entry transfers and to receive and transmit payments with respect to the notes on your behalf. We, the underwriters, and the trustee under the indenture have no responsibility for any aspect of the actions of DTC or any of its direct or indirect participants. We, the underwriters, and the trustee under the indenture have no responsibility or liability for any aspect of the records kept by DTC or any of its direct or indirect participants relating to, or payments made on account of, beneficial ownership interests in the notes or for maintaining, supervising, or reviewing any records relating to such beneficial ownership interests. We also do not supervise these systems in any way.

The trustee will not recognize you as a holder under the indenture, and you can only exercise the rights of a holder indirectly through DTC and its direct participants. DTC has advised us that it will only take action regarding a note if one or more of the direct participants to whom the note is credited directs DTC to take such action and only in respect of the portion of the aggregate principal amount of the notes as to which that participant or participants has or have given that direction. DTC can only act on behalf of its direct participants. Your ability to pledge notes to non-direct participants, and to take other actions, may be limited because you will not possess a physical certificate that represents your notes.

Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the notes unless authorized by a direct participant in accordance with DTC's procedures. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants to whose accounts the notes are credited on the record date (identified in a listing attached to the omnibus proxy).

DTC has agreed to the foregoing procedures in order to facilitate transfers of the notes among its participants. However, DTC is under no obligation to perform or continue to perform those procedures, and may discontinue those procedures at any time.

"Attributable Indebtedness," when used with respect to any Sale-Leaseback Transaction, means, as at the time of determination, the present value (discounted at the rate set forth or implicit in the terms of the lease included in such transaction) of the total obligations of the lessee for rental payments (other than amounts required to be paid on account of property taxes, maintenance, repairs, insurance, assessments, utilities, operating and labor costs and other items that do not constitute payments for property rights) during the remaining term of the lease included in such Sale-Leaseback Transaction (including any period for which such lease has been extended). In the case of any lease that is terminable by the lessee upon the payment of a penalty or other termination payment, such amount shall be the lesser of the amount determined assuming termination upon the first date such lease may be terminated (in which case the amount shall also include the amount of the penalty or termination payment, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated) or the amount determined assuming no such termination.

"Consolidated Net Tangible Assets" means, at any date of determination, the total amount of assets of ENLC and its consolidated Subsidiaries after deducting therefrom:

all as set forth, or on a pro forma basis would be set forth, on the consolidated balance sheet of ENLC and its consolidated Subsidiaries for ENLC's most recently completed fiscal quarter for which financial statements have been filed with the SEC, prepared in accordance with generally accepted accounting principles.

"Credit Agreement" means the Revolving Credit Agreement, dated as of December 11, 2018, among ENLC, Bank of America, N.A., as Administrative Agent, and the other agents and lenders party thereto, as amended, restated, or otherwise modified from time to time, and any successor or replacement agreement with banks or other financial institutions that provides for revolving loans to ENLC or ENLK.

"Exchange Act" means the Securities Exchange Act of 1934, as amended, and any successor statute.

"Indebtedness" of any Person at any date means any obligation created or assumed by such Person for the repayment of borrowed money or any guaranty thereof.

"Managing Member" means EnLink Midstream Manager, LLC, a Delaware limited liability company, and its successors as managing member of ENLC.

"Person" means any individual, corporation, partnership, limited liability company, joint venture, incorporated or unincorporated association, joint-stock company, trust, unincorporated organization, government or any agency or political subdivision thereof or any other entity.

"Principal Property" means, whether owned or leased on the date of the initial issuance of the notes or thereafter acquired:

"Principal Subsidiary" means any Subsidiary owning or leasing, directly or indirectly through ownership in another Subsidiary, any Principal Property.

"Subsidiary" means, as to any Person, (1) any corporation, association or other business entity (other than a partnership or limited liability company) of which more than 50% of the outstanding capital stock having ordinary voting power is at the time owned or controlled, directly or indirectly, by such Person or one or more of the other Subsidiaries of such Person or (2) any general or limited partnership or limited liability company, (a) the sole general partner or member of which is the Person or a Subsidiary of the Person or (b) if there is more than one general partner or member, either (i) the only managing general partners or managing members of such partnership or limited liability company are such Person or Subsidiaries of such Person or (ii) such Person owns or controls, directly or indirectly, a majority of the outstanding general partner interests, member interests or other voting equities of such partnership or limited liability company, respectively.

"Subsidiary Guarantor" means each Subsidiary of ENLC that guarantees the notes pursuant to the terms of the indenture but only so long as such Subsidiary is a guarantor with respect to the notes on the terms provided for in the indenture.

"Term Loan" means the Term Loan Agreement, dated as of December 11, 2018, among ENLK, Bank of America, N.A., as Administrative Agent, the other agents and lenders party thereto, and pursuant to the New Borrower Joinder and Assumption Agreement, dated as of January 25, 2019, ENLC, and as further amended, restated, or supplemented from time to time, and any successor or replacement agreement with banks or other financial institutions that provides for one or more term loans to ENLC or ENLK.

The following discussion summarizes the material U.S. federal income tax considerations relevant to the acquisition, ownership, and disposition of the notes, but does not purport to be a complete analysis of all potential tax effects. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (the "Code"), applicable Treasury regulations promulgated and proposed thereunder (the "Treasury Regulations"), Internal Revenue Service ("IRS") rulings and pronouncements, and judicial decisions, all as of the date hereof and all of which are subject to change at any time. Any such change may be applied retroactively in a manner that could adversely affect a holder of the notes. We cannot assure you that the IRS will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. federal tax consequences of acquiring, holding, or disposing of the notes.

This discussion is limited to holders purchasing the notes pursuant to this offering for cash at their original "issue price" (i.e., the first price at which a substantial amount of the notes is sold to the public for cash other than to bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents, or wholesalers) and who hold the notes as "capital assets" within the meaning of Section 1221 of the Code (generally, property held for investment). Moreover, the effects of other U.S. federal tax laws (such as estate and gift tax laws) and any applicable state, local, or foreign tax laws are not discussed. In addition, this discussion does not address all of the U.S. federal income tax considerations that may be relevant to a particular holder in light of the holder's particular circumstances, or to holders subject to special rules, including, without limitation:

If a partnership or other entity taxed as a partnership for U.S. federal income tax purposes holds notes, the tax treatment of the partners in the partnership generally will depend on the status of the particular partner in question, certain determinations made at the partner level and the activities of the partnership. If you are a partnership acquiring the notes or a partner of such a partnership, you are urged to consult your own tax advisor about the tax consequences of acquiring, holding, and disposing of the notes.

YOU ARE URGED TO CONSULT YOUR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, OR DISPOSITION OF THE NOTES UNDER OTHER U.S. FEDERAL TAX LAWS (INCLUDING ESTATE AND GIFT TAX LAWS) OR UNDER THE LAWS OF ANY STATE, LOCAL, OR FOREIGN JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

In certain circumstances (please read "Description of the Notes — Optional Redemption"), we may elect to pay amounts on the notes that are in excess of the stated interest or principal on the notes. These potential payments may implicate the provisions of the Treasury Regulations relating to contingent payment debt instruments. We do not intend to treat the possibility of paying such additional amounts as causing the notes to be treated as contingent payment debt instruments. It is possible, however, that the IRS may take a different position, in which case, if such position is sustained, you might be required to accrue ordinary interest income at a higher rate than the stated interest rate and to treat as ordinary income rather than capital gain any gain realized on the taxable disposition of the note. Our position that the notes are not treated as contingent payment debt instruments may be binding on you unless you disclose a contrary position to the IRS in the manner required by applicable Treasury Regulations. The remainder of this discussion assumes that the notes are not contingent payment debt instruments.

The following summary will apply to you if you are a U.S. holder of the notes. You are a "U.S. holder" for purposes of this discussion if you are a beneficial owner of a note and, for U.S. federal income tax purposes, you are or are treated as:

Stated interest paid or accrued on the notes generally will be taxable to you as ordinary income at the time such interest is received or accrued, in accordance with your regular method of accounting for U.S. federal income tax purposes. Thus, if you use the accrual method of accounting for U.S. federal income tax purposes, stated interest on a note will be taxable to you as ordinary income at the time it accrues. If you use the cash method of accounting for U.S. federal income tax purposes, stated interest on a note will be taxable to you as ordinary income at the time it is received.

You will generally recognize taxable gain or loss on the sale, exchange, redemption, retirement, or other taxable disposition of a note equal to the difference, if any, between:

Your adjusted tax basis in a note generally will equal the amount that you paid for the note. Any gain or loss will be capital gain or loss and will be long-term capital gain or loss if at the time of the sale or other taxable disposition you have held the note for more than one year. Otherwise, such gain or loss will be short-term capital gain or loss. Currently, long-term capital gains recognized by individuals, estates, and trusts generally are subject to reduced rates of tax. The deductibility of capital losses is subject to limitations.

You may be subject to information reporting on interest on the notes and on the proceeds received upon the sale or other disposition (including a retirement or redemption) of the notes, and backup withholding also may apply to payments of such amounts. Certain U.S. holders, such as corporations, are generally exempt from information reporting and backup withholding. You will be subject to backup withholding if you are not otherwise exempt and you:

If you are a U.S. holder, you should consult your own tax advisors regarding your qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, if applicable. Backup withholding is not an additional tax, and you may use amounts withheld as a credit against your U.S. federal income tax liability, if any, or you may obtain a

refund if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide certain information to the IRS.

An additional 3.8% tax is imposed on the "net investment income" of certain U.S. citizens and resident aliens, and on the undistributed "net investment income" of certain estates and trusts. Among other items, "net investment income" generally includes gross income from interest and certain net gain from the disposition of property, such as the notes, less certain deductions. You should consult your tax advisors with respect to this additional tax and its applicability to your particular circumstances.

The following summary will apply to you if you are a non-U.S. holder of the notes. You are a "non-U.S. holder" for purposes of this discussion if you are a beneficial owner of notes that is an individual, corporation, estate, or trust that is not a U.S. holder.

Subject to the discussions below under "— Information Reporting and Backup Withholding" and "Material United States Federal Income Tax Considerations — FATCA Withholding," interest paid on a note to you that is not effectively connected with your conduct of a U.S. trade or business generally will be exempt from U.S. federal income and withholding tax provided that:

If you cannot satisfy the requirements described above you generally will be subject to U.S. federal withholding tax at the rate of 30% on payments of interest on the notes that are not effectively connected with the conduct by you of a trade or business in the United States. However, you may be entitled to a reduction in or an exemption from withholding tax on interest if you provide the applicable withholding agent with a properly executed IRS Form W-8BEN or

W-8BEN-E claiming an exemption from or reduction of the withholding tax under the benefit of an applicable tax treaty.

If interest paid to you is effectively connected with your conduct of a U.S. trade or business (and, if required by an applicable income tax treaty, you also maintain a U.S. permanent establishment to which such interest is attributable), then, although exempt from U.S. federal withholding tax, you generally will be subject to U.S. federal income tax on such interest in the same manner as if you were a U.S. holder. In addition, if you are a foreign corporation, such interest may be subject to a branch profits tax at a rate of 30% or lower applicable treaty rate. To claim the exemption, you generally must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that interest paid on a note is not subject to withholding tax because it is effectively connected with the conduct by you of a trade or business within the United States.

The certifications described above must be provided to the applicable withholding agent prior to the payment of interest and generally must be updated periodically. If you do not timely provide the applicable withholding agent with the required certification, but qualify for a reduced rate under an applicable income tax treaty, you generally may obtain a refund of any excess amounts withheld under these rules by timely filing an appropriate claim for refund with the IRS. You should consult your tax advisors regarding your entitlement to benefits under any applicable income tax treaty.

Subject to the discussion below under "— Information Reporting and Backup Withholding," any gain realized by you on the sale, exchange, retirement, redemption, or other disposition of a note generally will not be subject to U.S. federal income tax unless:

If you recognize gain described in the first bullet point above, you will be required to pay U.S. federal income tax on the net gain derived from the sale generally in the same manner as if you were a U.S. holder, and if you are a foreign corporation, you may also be required to pay an additional branch profits tax at a 30% rate (or a lower rate if so specified by an applicable income tax treaty). If you are a non-U.S. holder described in the second bullet point above, you will be subject to U.S. federal income tax at a rate of 30% (or, if applicable, a lower treaty rate) on the gain derived from the sale or other disposition of the note, which may be offset by certain U.S. source capital losses, even though you are not considered a resident of the United States.

Any amount allocable to accrued and unpaid interest generally will be taxable as interest and may be subject to the rules discussed above in "Material U.S. Federal Income Tax Consequences to Non-U.S. Holders — Taxation of Interest."

You should consult your tax advisor regarding potentially applicable income tax treaties that may provide for different rules.

You generally will not be subject to backup withholding and certain information reporting with respect to payments of interest on the notes if you have provided the statement described above under "— Taxation of Interest" and the applicable withholding agent does not have actual knowledge or reason to know that you are a "United States person," within the meaning of the Code. In addition, you will not be subject to backup withholding or certain information reporting with respect to the proceeds of the sale or other disposition of a note (including a retirement or redemption of a note) within the United States or conducted through certain U.S.-related brokers, if the payor receives the statement described above and does not have actual knowledge or reason to know that you are a United States person or you otherwise establish an exemption. However, we will be required to report annually to the IRS and to you the amount of, and the tax withheld with respect to, any interest paid to you, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which you reside.

You generally will be entitled to credit any amounts withheld under the backup withholding rules against your U.S. federal income tax liability, if any, or you may obtain a refund if the amounts withheld exceed your actual U.S. federal income tax liability and you timely provide certain information to the IRS.

Under Sections 1471 through 1474 of the Code and administrative guidance issued thereunder (referred to as "FATCA"), a 30% U.S. federal withholding tax is generally imposed on interest payments on the notes if paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code), unless (i) in the case of a foreign financial institution, such institution enters into an agreement with the Treasury Department to withhold on certain payments and to collect and provide substantial information regarding U.S. account holders, including certain account holders that are foreign entities with U.S. owners, (ii) in the case of a non-financial foreign entity, such entity certifies that it does not have any "substantial United States owners" (as defined in the Code) or provides the withholding agent with a certification identifying its direct or indirect substantial United States owners, or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as an IRS Form W-8BEN-E). Under certain circumstances, you might be eligible for refunds or credits of such taxes from the IRS. Intergovernmental agreements regarding FATCA between the United States and certain other countries may modify the foregoing requirements. Prior to the issuance of recently proposed Treasury Regulations, withholding taxes under FATCA would have applied to gross proceeds from the sale or other disposition of a note on or after January 1, 2019. However, the proposed Treasury Regulations provide that such gross proceeds are not subject to withholding taxes under FATCA. Taxpayers may rely on these proposed Treasury Regulations until they are revoked or final Treasury Regulations are issued.

You should consult with your tax advisor regarding these rules as they apply to the notes.

THE PRECEDING DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. IF YOU ARE A PROSPECTIVE INVESTOR YOU SHOULD CONSULT YOUR OWN TAX ADVISOR REGARDING THE PARTICULAR FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES OF PURCHASING, HOLDING, AND, DISPOSING OF OUR NOTES.

RBC Capital Markets, LLC, BMO Capital Markets Corp., SunTrust Robinson Humphrey, Inc., and Wells Fargo Securities, LLC are acting as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the principal amount of notes set forth opposite the underwriter's name.

The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the notes if they purchase any of the notes.

Notes sold by the underwriters to the public will initially be offered at the initial public offering prices set forth on the cover of this prospectus supplement. Any notes sold by the underwriters to securities dealers may be sold at a discount from the public offering price of up to % of the principal amount of the notes. Any such securities dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price not to exceed % of the principal amount of the notes. If all the notes are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms.

The following table shows the underwriting discounts that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

The notes are a new issue of securities with no established trading market. The notes will not be listed on any securities exchange or on any automated dealer quotation system. Certain of the

underwriters have informed us that they may make a market in the notes after completion of the offering, but they are not obligated to do so and may discontinue any market-making activities at any time and without notice. No assurance can be given as to the liquidity of the trading market of the notes or that an active public market for the notes will develop or continue. If an active public market for the notes does not develop or continue, the market price and liquidity of the notes may be adversely affected.

In connection with the offering, the underwriters may purchase and sell notes in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions and stabilizing purchases.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time without notice.

Because affiliates of RBC Capital Markets, LLC, BMO Capital Markets Corp., and Wells Fargo Securities, LLC are lenders under our revolving credit facility and may receive more than 5% of the net proceeds of this offering due to our repayment of portions of the revolving credit facility by us, such underwriters may be deemed to have a "conflict of interest" under FINRA Rule 5121. Accordingly, this offering is being made in compliance with the requirements of FINRA Rule 5121.

The underwriters are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing, and brokerage activities. The underwriters and their respective affiliates have in the past performed commercial banking, investment banking, and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses and may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (which may include bank loans and/or credit default swaps) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities

and instruments. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates.

In addition, affiliates of certain of the underwriters, including the underwriters named above that may receive more than 5% of the net proceeds of this offering, are lenders, and in some cases agents or managers for the lenders, under our revolving credit facility and term loan. Accordingly, such underwriters and affiliates will receive the proceeds from this offering as a result of the repayment of borrowings under our revolving credit facility. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge and certain other of those underwriters or their affiliates may hedge their credit exposure to us consistent with their customary risk management policies. A typical hedging strategy would include these underwriters or their affiliates hedging 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 notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes. The underwriters 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.

The notes may not and will not be publicly offered, distributed or re-distributed in or from Switzerland and neither this prospectus supplement nor any other solicitation for investments in the notes may be communicated or distributed in Switzerland in any way that could constitute a public offering within the meaning of Articles 1156 or 652a of the Swiss Code of Obligations. The notes are not a collective investment within the meaning of the Federal Collective Investment Schemes Act of June 23, 2006 (Bundesgesetz über die kollektiven Kapitalanlagen, KAG). This prospectus supplement may not be copied, reproduced, distributed or passed on to others without the prior written consent of Goldman Sachs & Co. LLC and Mizuho Securities USA LLC. This prospectus supplement is not a prospectus within the meaning of Articles 1156 and 652a of the Swiss Code of Obligations or a listing prospectus according to article 27 of the Listing Rules of the Swiss Exchange and may not comply with the information standards required thereunder. We will not apply for a listing of the notes on any Swiss stock exchange or other Swiss regulated market and this prospectus supplement may not comply with the information required under the relevant listing rules. The notes offered hereby have not been and will not be registered with the Swiss Federal Financial Market Supervisory Authority (FINMA) and have not been and will not be authorized under the Federal Collective Investment Schemes Act of June 23, 2006 (Bundesgesetz über die kollektiven Kapitalanlagen, KAG). The investor protection afforded by the Federal Collective Investment Schemes Act (Bundesgesetz über die kollektiven Kapitalanlagen, KAG) does not extend to the acquirers of the notes.

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic

Area ("EEA"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, "MiFID II"); or (ii) a customer within the meaning of Directive 2002/92/EC, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the "Prospectus Directive"). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPS Regulation.

Accordingly, this prospectus supplement and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the notes may not be circulated or distributed, nor may the notes be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor (as defined in Section 4A of the Securities and Futures Act, Chapter 289 of Singapore (the "SFA")) under Section 274 of the SFA, (ii) to a relevant person (as defined in Section 275(2) of the SFA) pursuant to Section 275(1) of the SFA, or any person pursuant to Section 275(1A) of the SFA, and in accordance with the conditions specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA, in each case subject to conditions set forth in the SFA.

We expect that delivery of the notes will be made against payment therefor on or about the closing date specified on the cover page of this prospectus supplement, which will be the third business day following the date of this prospectus supplement. This settlement cycle is referred to as "T+3." Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of this prospectus supplement will be required, by virtue of the fact that the notes initially will settle T+3, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of notes who wish to trade notes on the date of this prospectus supplement should consult their own advisor.

Financial information concerning ENLK is included in ENLK's consolidated financial statements, which are included in the periodic reports filed by ENLK pursuant to the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which are incorporated herein by reference. See "Information Incorporated By Reference."

The executive offices of ENLC and ENLK are located at 1722 Routh Street, Suite 1300, Dallas, Texas 75201, and our telephone number is (214) 953-9500.

An investment in our securities involves a high degree of risk. Before you invest in our securities, you should carefully consider the risk factors described in ENLC's and ENLK's most recent annual report on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K, all of which are incorporated herein by reference and any other risk factors that may be described in the applicable prospectus supplement, together with all of the other information included in this prospectus, any prospectus supplement, and the documents we incorporate by reference. If any of these risks were to occur, our business, financial condition, or results of operations could be adversely affected. In that case, the trading price of our units or debt securities could decline and you could lose all or part of

your investment. When we offer and sell any securities pursuant to a prospectus supplement, we may include additional risk factors relevant to such securities in the prospectus supplement.

Some of the information included in this prospectus, any prospectus supplement, and the documents we incorporate by reference herein contain forward-looking statements that are based on information currently available to management as well as management's assumptions and beliefs. All statements, other than statements of historical fact, included in this prospectus, any prospectus supplement, and the documents we incorporate by reference constitute forward-looking statements, including but not limited to statements identified by the words "forecast," "may," "believe," "will," "should," "plan," "predict," "anticipate," "intend," "estimate," "expect," and similar expressions. Such statements reflect our current views with respect to future events, based on what we believe are reasonable assumptions; however, such statements are subject to a number of assumptions, risks, and uncertainties. In addition to the specific uncertainties discussed elsewhere in this prospectus, any prospectus supplement, and the documents we incorporate by reference herein, the risk factors set forth in "Risk Factors" may affect our performance and results of operations. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may differ materially from those in the forward-looking statements. We do not assume any obligation to update or review any forward-looking statements or information, whether as a result of new information, future events, or otherwise.

Unless we specify otherwise in any prospectus supplement, we will use the net proceeds we receive from the sale of securities covered by this prospectus for general limited liability company purposes, which may include, among other things:

The actual application of proceeds from the sale of any particular offering of securities 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. The net proceeds may be invested temporarily until they are used for their stated purpose.

We will issue debt securities under an indenture among EnLink Midstream, LLC, any guarantors party thereto, and a trustee that we will name in the related prospectus supplement. If we offer senior debt securities, we will issue them under a senior indenture. If we offer subordinated debt securities, we will issue them under a subordinated indenture. The term "Trustee" as used in this prospectus refers to the trustee under any of the above indentures. References in this prospectus to an "Indenture" are to the particular indenture under which we may issue a series of debt securities, in each case as supplemented by a supplemental indenture that establishes the form and terms of that series of debt securities. Any series of debt securities that we may issue will be governed by the provisions of the related Indenture and those made part of that Indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

This description is a summary of the material provisions of the debt securities and the Indentures. We urge you to read the forms of Indentures filed as exhibits to the registration statement of which this prospectus is a part because those Indentures, and not this description, govern your rights as a holder of debt securities. When we offer and sell any particular series of our debt securities under this prospectus, we will file the supplemental indenture establishing the form and terms of that series as an exhibit to a Current Report on Form 8-K.

The Indenture will not limit the total amount of debt securities that may be issued. Debt securities of any series, however, will be issued only up to the aggregate amount authorized for such series and set forth in the prospectus supplement pertaining to that series.

We will prepare a prospectus supplement and either an indenture supplement or a board resolution of our managing member and accompanying officers' certificate relating to any series of debt securities that we offer, which will include specific terms relating to some or all of the following:

This description of debt securities will be deemed modified, amended, or supplemented by any description of any series of debt securities set forth in a prospectus supplement related to that series.

The prospectus supplement will also describe any material United States federal income tax consequences or other special considerations regarding the applicable series of debt securities, including those relating to:

Interest payments on debt securities in certificated form may be made by check mailed to the registered holders or, if so stated in the applicable prospectus supplement, at the option of a holder, by wire transfer to an account designated by the holder.

Unless otherwise provided in the applicable prospectus supplement, debt securities may be transferred or exchanged at the office of the Trustee at which its corporate trust business is principally administered in the United States, subject to the limitations provided in the Indenture, without the payment of any service charge, other than any applicable tax or other governmental charge.

Any funds paid to the Trustee or any paying agent for the payment of amounts due on any debt securities that remain unclaimed for two years will be returned to us, and the holders of the debt securities must look only to us for payment after that time.

Our payment obligations under any series of debt securities may be jointly and severally, fully and unconditionally guaranteed by one or more guarantors. The applicable prospectus supplement will describe the terms of any guarantee by the guarantors.

The obligations of each guarantor under its guarantee of the debt securities will be limited to the maximum amount that will not result in the obligations of the guarantor under the guarantee constituting a fraudulent conveyance or fraudulent transfer under federal or state law, after giving effect to:

The guarantee of any guarantor may be released under certain circumstances. If no default has occurred and is continuing under the Indenture, and to the extent not otherwise prohibited by the Indenture, a guarantor will be unconditionally released and discharged from the guarantee:

If a series of debt securities is guaranteed by the guarantors and is designated as subordinate to our senior indebtedness, then the guarantees by the guarantors will be subordinated to the senior indebtedness of the guarantors to substantially the same extent as the series is subordinated to our senior indebtedness. See "—Provisions Relating Only to the Subordinated Debt Securities—Subordinated Debt Securities Subordinated to Senior Indebtedness."

Payment of Principal, any Premium, Interest, or Additional Amounts. We will duly and punctually pay the principal of, and premium and interest on, or any additional amounts payable with respect to, any debt securities of any series in accordance with their terms and the terms of the Indenture.

Maintenance of Office or Agency. We will maintain an office or agency in each place of payment for each series of debt securities for notice and demand purposes and for the purposes of presenting or surrendering debt securities for payment, registration of transfer or exchange.

Additional Covenants. Any additional covenants with respect to any series of debt securities will be set forth in the supplemental indenture or board resolution and officer's certificate and prospectus supplement relating thereto.

Unless otherwise specified in a supplement to the Indenture, each of the following events will be an "Event of Default" under the Indenture with respect to a series of debt securities:

If an Event of Default, other than an Event of Default described in the fifth bullet point above, occurs and is continuing with respect to a series of debt securities, the Trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the entire principal of, premium, if any, and accrued and unpaid interest, if any, on all the debt securities of that series to be due and payable immediately. If an Event of Default described in the fifth bullet point above occurs, the principal of, premium, if any, and accrued and unpaid interest on all outstanding debt securities of all series will become immediately due and payable without any declaration of acceleration or other act on the part of the Trustee or any holders.

A default under the fourth bullet point above will not constitute an Event of Default until the Trustee or the holders of 25% in principal amount of the outstanding debt securities of that series notifies us of the default and such default is not cured within 60 days after receipt of notice.

The holders of a majority in principal amount of the outstanding debt securities of a series may rescind any declaration of acceleration by the Trustee or the holders with respect to the debt securities of that series, but only if:

If an Event of Default occurs and is continuing with respect to a series of debt securities, the Trustee will be under no obligation, except as otherwise provided in the Indenture, to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders of the debt

securities of that series, unless such holders have offered to the Trustee reasonable indemnity or security against any costs, liability, or expense. No holder may pursue any remedy with respect to the Indenture or the debt securities of any series, except to enforce the right to receive payment of principal, premium, or interest on its own debt securities when due, unless:

The holders of a majority in principal amount of the outstanding debt securities of a series have the right, subject to certain restrictions, to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee or of exercising any right or power conferred on the Trustee with respect to that series of debt securities. The Trustee, however, may refuse to follow any direction that:

Within 30 days after the occurrence of an Event of Default, we are required to give written notice to the Trustee and indicate the status of the default and what action we are taking or propose to take to cure the default. In addition, we are required to deliver to the Trustee, within 120 days after the end of each fiscal year, a compliance certificate indicating that we have complied with all covenants contained in the Indenture or whether any default or Event of Default has occurred during the previous year.

Within 90 days after the occurrence of any default known to it, the Trustee must send to each holder of debt securities of the affected series a notice of the default. Except in the case of a default in the payment of principal, premium, or interest with respect to any series of debt securities, the Trustee may withhold such notice, but only if and so long as the board of directors, the executive committee, or a committee of directors or responsible officers of the Trustee in good faith determines that withholding such notice is in the interests of the holders.

We may supplement or amend the Indenture without the consent of any holder of debt securities to, among other things:

In addition, we may amend the Indenture if the holders of a majority in principal amount of all debt securities of each series that would be affected then outstanding under the Indenture consent to it. We may not, however, without the consent of each holder of outstanding debt securities of each series that would be affected, amend the Indenture to:

It shall not be necessary for the consent of the holders under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under the Indenture requiring the consent of the holders becomes effective, we are required to send to all holders a notice briefly describing the amendment. The failure to give, or any defect in, such notice, however, will not impair or affect the validity of the amendment.

The holders of a majority in aggregate principal amount of the outstanding debt securities of each affected series, on behalf of all such holders, and subject to certain rights of the Trustee, may waive:

The Indenture will be discharged and will cease to be of further effect as to all outstanding debt securities of any series issued thereunder, when:

Notwithstanding such satisfaction and discharge, our obligations to compensate and indemnify the Trustee, to pay additional amounts, if any, in respect of debt securities in certain circumstances, and to transfer or exchange debt securities pursuant to the terms thereof and our obligations and the obligations of the Trustee to hold funds in trust and to apply such funds pursuant to the terms of the Indenture, with respect to issuing temporary debt securities, with respect to the registration, transfer and exchange of debt securities, with respect to the replacement of mutilated, destroyed, lost, or stolen debt securities and with respect to the maintenance of an office or agency for payment, shall in each case survive such satisfaction and discharge.

At any time, we may terminate, with respect to debt securities of a particular series, all our obligations under such series of debt securities and the Indenture, which we call a "legal defeasance." If we decide to make a legal defeasance, however, we may not terminate our obligations specified in the Indenture, including those:

At any time we may also effect a "covenant defeasance," which means we have elected to terminate our obligations under the additional covenants established pursuant to the terms of a particular series of debt securities, which covenants are not described in the prospectus but will be described in the prospectus supplement applicable to such series, and any Event of Default resulting from a failure to observe such covenants.

The legal defeasance option may be exercised notwithstanding a prior exercise of the covenant defeasance option. If the legal defeasance option is exercised, payment of the affected series of debt securities may not be accelerated because of an Event of Default with respect to that series. If the covenant defeasance option is exercised, payment of the affected series of debt securities may not be accelerated because of an Event of Default with respect to the fourth and sixth (and, with respect to any guarantor, the fifth) bullet points under "—Events of Default, Remedies, and Notice—Events of Default" above or an Event of Default that is added specifically for such series and described in a prospectus supplement.

None of our managing member nor any director, officer, employee, incorporator, manager, or unitholder or other owner of equity of our managing member, us, or any guarantor, as such, will be liable for:

By accepting a debt security, each holder will be deemed to have waived and released all such liability. This waiver and release are part of the consideration for the issuance of the debt securities. This waiver may not be effective, however, to waive liabilities under the Federal securities laws and it is the view of the SEC that such a waiver is against public policy.

Unless otherwise set forth in the prospectus supplement, the debt securities will not contain any provisions that protect the holders of the debt securities in the event of a change of control in us or in the event of a highly leveraged transaction, whether or not such transaction results in a change of control in us.

The senior debt securities will rank equally in right of payment with all of our other unsubordinated debt. The senior debt securities will be effectively subordinated, however, to all of our secured debt to the extent of the value of the collateral securing such debt. We will disclose the amount of our secured debt in the prospectus supplement.

The subordinated debt securities will rank junior in right of payment to all of our and our guarantors' Senior Indebtedness. "Senior Indebtedness" will be defined in a supplemental indenture respecting any issuance of a series of subordinated debt securities, and the definition will be set forth in the prospectus supplement.

The Indenture respecting any series of subordinated debt securities will provide that no payment of principal, interest, and any premium on the subordinated debt securities or any related guarantee may be made in the event:

The Indenture respecting any series of subordinated debt securities will not limit the amount of Senior Indebtedness that we may incur, unless otherwise indicated in the prospectus supplement.

The debt securities of a particular series may be issued in whole or in part in the form of one or more global certificates that will be deposited with the Trustee as custodian for The Depository Trust Company, New York, New York ("DTC"). This means that we will not issue certificates to each holder except in the limited circumstances described below. Instead, one or more global debt securities will be issued to DTC, who will keep a computerized record of its participants (for example, your broker) whose clients have purchased the debt securities. The participant will then keep a record of its clients who purchased the debt securities. Unless it is exchanged in whole or in part for a certificated debt security, a global debt security may not be transferred, except that DTC, its nominees and their successors may transfer a global debt security as a whole to one another.

Beneficial interests in global debt securities will be shown on, and transfers of global debt securities will be made only through, records maintained by DTC and its participants.

DTC has provided us the following information: DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the United States Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered under the provisions of Section 17A of the Exchange Act. DTC holds securities that its participants ("Direct Participants") deposit with DTC. DTC also records the settlement among Direct Participants of securities transactions, such as transfers and pledges, in deposited securities through computerized records for Direct Participants' accounts. This eliminates the need to exchange certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations.

DTC's book-entry system is also used by other organizations such as securities brokers and dealers, banks and trust companies that work through a Direct Participant. The rules that apply to DTC and its participants are on file with the SEC.

DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries.

We will wire all payments on the global debt securities to DTC's nominee. We and the Trustee will treat DTC's nominee as the owner of the global debt securities for all purposes. Accordingly, we, the Trustee, and any paying agent will have no direct responsibility or liability to pay amounts due on the global debt securities to owners of beneficial interests in the global debt securities.

It is DTC's current practice, upon receipt of any payment on the global debt securities, to credit Direct Participants' accounts on the payment date according to their respective holdings of beneficial interests in the global debt securities as shown on DTC's records. In addition, it is DTC's current practice to assign any consenting or voting rights to Direct Participants whose accounts are credited with debt securities on a record date, by using an omnibus proxy. Payments by participants to owners of beneficial interests in the global debt securities, and voting by participants, will be governed by the customary practices between the participants and owners of beneficial interests, as is the case with debt securities held for the account of customers registered in "street name." However, payments will be the responsibility of the participants and not of DTC, the Trustee, or us.

Debt securities represented by a global debt security will be exchangeable for certificated debt securities with the same terms in authorized denominations only if:

Each Indenture and all of the debt securities will be governed by the laws of the State of New York.

We will enter into each Indenture with a Trustee that is qualified to act under the Trust Indenture Act and with any other trustee chosen by us and appointed in a supplemental indenture for a particular series of debt securities. Unless we otherwise specify in the applicable prospectus supplement, the

Trustee for each series of debt securities will be Wells Fargo Bank, National Association. We may maintain a banking relationship in the ordinary course of business with our Trustee and one or more of its affiliates.

If the Trustee has or acquires a conflicting interest within the meaning of the Trust Indenture Act after a default has occurred and is continuing, the Trustee must either eliminate its conflicting interest within 90 days, apply to the SEC for permission to continue as Trustee or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and the applicable Indenture. Any resignation will require the appointment of a successor trustee under the applicable Indenture in accordance with the terms and conditions of such Indenture.

The Trustee may resign or be removed by us with respect to one or more series of debt securities and a successor Trustee may be appointed to act with respect to any such series. The holders of a majority in aggregate principal amount of the debt securities of any series may remove the Trustee with respect to the debt securities of such series.

Each Indenture will contain certain limitations on the right of the Trustee, in the event that it becomes a creditor of us, to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise.

The Trustee is required to submit an annual report to the holders of the debt securities regarding, among other things, the Trustee's eligibility to serve as such, the priority of the Trustee's claims regarding certain advances made by it, and any action taken by the Trustee materially affecting the debt securities.

Each Indenture will provide that, in addition to other certificates or opinions that may be specifically required by other provisions of the Indenture, every application by us for action by the Trustee will be accompanied by a certificate of certain of our officers and an opinion of counsel (who may be our counsel) stating that, in the opinion of the signers, all conditions precedent to such action have been complied with by us.

Our common units represent non-managing membership interests in EnLink Midstream, LLC. Our unitholders are entitled to participate in cash distributions and exercise the rights and privileges available to non-managing members under our operating agreement. The following summary of our common units, our certificate of formation, and our operating agreement does not purport to be complete and is qualified in its entirety by reference to the provisions of applicable law and to our certificate of formation and our operating agreement which are filed as exhibits to the registration statement of which this prospectus is a part. Our common units are traded on the NYSE under the symbol "ENLC."

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

There will be no charge to our unitholders for disbursements of cash distributions by us. 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 in that capacity, except for any liability due to any gross negligence or intentional misconduct of the indemnified person or entity.

The transfer agent may resign by providing us notice. We may also remove the transfer agent. The resignation or removal of the transfer agent will become effective upon our appointment of a successor transfer agent and registrar and its acceptance of the appointment. If no successor is appointed, our managing member may act as the transfer agent and registrar until a successor is appointed.

By transfer of our common units in accordance with our operating agreement, each transferee of our common units will be admitted as a non-managing member with respect to our common units transferred when such transfer is reflected in our books and records and such transferee becomes the record holder of our common units transferred. Each transferee:

Our board of directors will cause any transfers to be recorded on our books and records from time to time as necessary to ensure their accuracy.

We may, at our discretion, treat the nominee holder of any of our common units 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.

Our common units are securities and any transfers are subject to the laws governing transfer of securities. In addition to other rights acquired upon transfer, the transferor gives the transferee the right to become a non-managing member for the transferred common units.

Until any 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.

Except as described under "Description of Our Operating Agreement—Issuance of Additional Interests," we may issue additional membership interests and options, rights, warrants, appreciation rights, tracking, profit, and phantom interests and other derivative instruments relating to, convertible into, or exchangeable for the membership interests for any company 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 managing member, all without the approval of our unitholders. In accordance with Delaware law and the provisions of our operating agreement, any additional membership interests that we issue may, in the sole discretion of our managing member, have special voting rights to which the common units are not entitled.

The following is a description of the general terms and provisions of our membership interests. The particular terms of any class or series of membership interests will be described in the applicable prospectus supplement and the amendment to our operating agreement relating to that class or series of membership interests, which will be filed as an exhibit to or incorporated by reference in this prospectus at or before the time of issuance of any such series of membership interests. If so indicated in a prospectus supplement, the terms of any such class or series may differ from the terms set forth below.

Our managing member is authorized to approve the issuance of one or more classes or series of membership interests without further authorization of the unitholders and to fix the number of securities, the designations, preferences, rights, powers, and duties of any such class or series.

The applicable prospectus supplement will set forth the number of securities, particular designations, relative rights and preferences and the limitations of any class or series of membership interests in respect of which this prospectus is delivered. The particular terms of any such class or series will include the following:

The membership interests will be fully paid and non-assessable when issued upon full payment of the purchase price therefor. The prospectus supplement will contain, if applicable, a description of the material U.S. federal income tax consequences relating to the purchase and ownership of the class or series of membership interests offered by the prospectus supplement. The transfer agent, registrar, and distributions disbursement agent for the membership interests will be designated in the applicable prospectus supplement.

The following is a summary of the material provisions of our operating agreement. Our operating agreement is included as an exhibit to the registration statement of which this prospectus constitutes a part. We summarize certain other provisions of the operating agreement elsewhere in this prospectus, including in "Description of the Common Units," "Cash Distribution Policy," and "Material United States Federal Income Tax Considerations."

We were organized on October 16, 2013 and will have a perpetual existence unless terminated pursuant to the terms of our operating agreement.

Our purpose, as set forth in our operating agreement is limited to any business activity that is approved by our managing member, in its sole discretion, and that lawfully may be conducted by a limited liability company organized under Delaware law. Although our managing member has the ability to cause us and our subsidiaries to engage in activities other than the business of owning, operating, developing, and acquiring crude oil and natural gas gathering and processing assets and the owning of equity securities in ENLK, our managing member may decline to do so in its sole discretion. Our managing member is generally authorized to perform all acts it determines to be necessary or appropriate to carry out the purposes of, and to conduct, our business.

Unitholders are not obligated to make additional capital contributions, except as described below under "—Limited Liability."

The following is a summary of the unitholder vote required for approval of the matters specified below. Matters that require the approval of a "unit majority" require the approval of a majority of the common units and our Class C common units representing limited liability company interests in us (the "Class C Common Units" and, together with our common units, the "ENLC Units"), voting together as a single class. Each Class C Common Unit will be entitled to the number of votes equal to the number of common units into which a Series B Cumulative Convertible Preferred Unit representing a limited partner interest in ENLK (an "ENLK Series B Unit") is then exchangeable (which is the product of the number of ENLK Series B Units being exchanged multiplied by 1.15 (subject to certain adjustments)). In addition, the holders of Class C Common Units are entitled to vote as a separate class on any matter that (i) adversely affects the rights, preferences, and privileges of the Class C Common Units or the ENLK Series B Units, including certain minority protections with respect to substantially the same matters for which the holders of ENLK Series B Units have approval rights under the limited partnership agreement of ENLK, or (ii) amends or modifies any of the terms of the Class C Common Units or ENLK Series B Units. The approval of a majority of the Class C Common Units is required to approve any matter for which the holders of Class C Common Units are entitled to vote as a separate class.

In voting their common units, affiliates of our managing member will have no duty or obligation whatsoever to us or our members, including any duty to act in our best interest or the best interests of our members.

Matter		Vote Requirement

Issuance of additional units		No approval right.
Amendment of the operating agreement		Certain amendments may be made by our managing member without the approval of the unitholders. Other amendments generally require the approval of a unit majority. See "—Amendment of the Operating Agreement."
Merger of or the sale of all or substantially all of our assets		Unit majority in certain circumstances. See "—Merger, Consolidation, Conversion, Sale, or Other Disposition of Assets."
Dissolution of EnLink Midstream		Unit majority. See "—Dissolution."
Continuation of our business upon dissolution		Unit majority. See "—Dissolution."
Withdrawal of our managing member		No approval right. See "—Withdrawal or Removal of Our Managing Member."
Removal of our managing member		Not less than 66²/3% of the outstanding ENLC Units, voting as a single class, including units held by our managing member and its affiliates. See "—Withdrawal or Removal of Our Managing Member."
Transfer of the interest of our managing member		No approval right. See "—Transfer of Managing Member Interest."
Transfer of ownership interests in our managing member		No approval right. See "—Transfer of Ownership Interests in Our Managing Member."

If any person or group other than our managing member and its affiliates acquires beneficial ownership of 20% or more of any class of units, that person or group loses voting rights on all of its units. This loss of voting rights does not apply to any person or group that acquires the units from our managing member or its affiliates (other than us) and any transferees of that person or group approved by our managing member or to any person or group who acquires the units with the written approval of our managing member, including Enfield Holdings, L.P., as the holder of the Class C Common Units and the ENLK Series B Units.

Our operating agreement is governed by Delaware law. Our operating agreement requires that any claims, suits, actions, or proceedings:

shall be exclusively brought in the Court of Chancery of the State of Delaware (or, if such court does not have subject matter jurisdiction thereof, any other court located in the State of Delaware with subject matter jurisdiction), regardless of whether such claims, suits, actions, or proceedings sound in contract, tort, fraud, or otherwise, are based on common law, statutory, equitable, legal, or other grounds, or are derivative or direct claims.

By acquiring our common units, you are irrevocably consenting to these limitations and provisions regarding claims, suits, actions, or proceedings and submitting to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or such other Delaware courts with subject matter jurisdiction) in connection with any such claims, suits, actions, or proceedings.

Under the DLLCA, a limited liability company may not make a distribution to a member if, after the distribution, all liabilities of the limited liability company, other than liabilities to members on account of their membership interests and liabilities for which the recourse of creditors is limited to specific property of the company, would exceed the fair value of the assets of the limited liability company. For the purpose of determining the fair value of the assets of a limited liability company, the DLLCA provides that the fair value of property subject to liability for which recourse of creditors is limited shall be included in the assets of the limited liability company only to the extent that the fair value of that property exceeds the non-recourse liability. The DLLCA provides that a member who receives a distribution and knew at the time of the distribution that the distribution was in violation of the DLLCA shall be liable to the limited liability company for the amount of the distribution for three years. Under the DLLCA, an assignee who becomes a substituted unitholder of a company is liable for the obligations of his assignor to make contributions to the company, except the assignee is not obligated for liabilities unknown to him at the time he became a unitholder and that could not be ascertained from the limited liability company agreement.

Our operating agreement authorizes us to issue an unlimited number of additional membership interests for the consideration and on the terms and conditions determined by our managing member without the approval of our unitholders, except that our operating agreement restricts our ability to issue any membership interests senior to or on parity with the ENLK Series B Units with respect to distributions on such membership interests or upon liquidation without the affirmative vote of the holders of a majority of our outstanding Class C Common Units, voting separately as a class.

It is possible that we will fund acquisitions through the issuance of additional common units or other membership interests. Holders of any additional common units issued by us will be entitled to share equally with the then-existing holders of our common units in distributions. In addition, the issuance of additional common units or other membership interests may dilute the value of the interests of the then-existing holders of our common units in our net assets.

In accordance with Delaware law and the provisions of our operating agreement, we may also issue additional membership interests that, as determined by our managing member, may have rights to distributions or special voting rights to which our common units are not entitled. In addition, except as

described above with respect to the ENLK Series B Units, our operating agreement does not prohibit our subsidiaries from issuing equity interests, which may effectively rank senior to our common units.

As of April 3, 2019, there were 59,154,779 Class C Common Units issued and outstanding. The holders of Class C Common Units are not entitled to distributions thereon of any kind. For each additional ENLK Series B Unit issued by ENLK pursuant to limited partnership agreement of ENLK, we will issue an additional Class C Common Unit to the applicable holder of ENLK Series B Units pursuant to our operating agreement, so that the number of Class C Common Units issued and outstanding will always equal the number of ENLK Series B Units issued and outstanding. In addition, upon any exchange of ENLK Series B Units for our common units, a number of Class C Common Units equal to the number of ENLK Series B Units subject to such exchange will be cancelled.

The voting rights of the Class C Common Units are described under "—Voting Rights" above.

Amendments to our operating agreement may be proposed only by our managing member. However, to the fullest extent permitted by law, our managing member will have no duty or obligation to propose or approve any amendment and may decline to do so free of any duty or obligation whatsoever to us or our members, including any duty to act in our best interest or in the best interest of our members. In order to adopt a proposed amendment, other than the amendments discussed below, our managing member is required to seek written approval of the holders of the number of common units required to approve the amendment or to call a meeting of the members to consider and vote upon the proposed amendment. Except as described below, an amendment must be approved by a unitholder majority.

The provision of our operating agreement preventing the amendments having the effects described in the clauses above can be amended upon the approval of the holders of at least 90% of the outstanding ENLC Units, voting together as a single class (including ENLC Units owned by our managing member and its affiliates).

Without Unitholder Approval. Our managing member may generally make amendments to our operating agreement without the approval of any member to reflect:

In addition, our managing member may make amendments to our operating agreement, without the approval of any member, if our managing member determines that those amendments:

Opinion of Counsel. For amendments of the type not requiring approval of a unitholder majority, our managing member will not be required to obtain an opinion of counsel that an amendment will not result in a loss of limited liability to the members in connection with any of the amendments. No other amendments to our operating agreement will become effective without the approval of holders of at least 90% of the outstanding ENLC Units, voting as a single class, unless we first obtain an opinion of counsel to the effect that the amendment will not affect the limited liability of any of its members under applicable law.

A merger, consolidation, or conversion of ENLC requires the prior consent of our managing member. However, our managing member will have no duty or obligation to consent to any merger, consolidation, or conversion and may decline to do so in its sole discretion.

In addition, our operating agreement generally prohibits our managing member from causing us to sell, exchange, or otherwise dispose of all or substantially all of (i) our assets and the assets of our subsidiaries, taken as a whole, or (ii) for so long as our Class C Common Units remain outstanding, the assets of ENLK and its subsidiaries, taken as a whole, in a single transaction or a series of related transactions, without the prior approval of the holders of a majority of the ENLC Units. Our managing member may, however, mortgage, pledge, hypothecate, or grant a security interest in all or substantially all of our assets and the assets of our subsidiaries or the assets of ENLK and its subsidiaries, taken as a whole, without such approval. Our managing member may also sell all or substantially all of our assets and our subsidiaries' assets or the assets of ENLK and its subsidiaries, taken as a whole, under a foreclosure or other realization upon those encumbrances without such approval. Finally, our managing member may consummate any merger without the prior approval of our members if (i) we are the surviving entity in the transaction, (ii) our managing member has received an opinion of counsel regarding limited liability matters, (iii) the transaction would not result in an amendment to our operating agreement (other than an amendment that our managing member could adopt without the consent of our unitholders), (iv) each of our common units would be an identical unit of ours following the transaction, and (v) the membership securities to be issued in the transaction do not exceed 20% of the outstanding membership interests immediately prior to the transaction.

If the conditions specified in our operating agreement are satisfied, our managing member may convert our company or any of our subsidiaries into a new limited liability entity or merge us or any of our subsidiaries into, or convey all of our assets to, a newly formed entity that has no assets, liabilities, or operations, if (i) the sole purpose of that conversion, merger, or conveyance is to effect a mere change in our legal form into another limited liability entity, (ii) we have received an opinion of counsel regarding limited liability matters, and (iii) our managing member determines that the governing instruments of the new entity provide the non-managing members and our managing member with substantially the same rights and obligations as contained in our operating agreement. Holders of

ENLC Units will not be entitled to dissenters' rights of appraisal under our operating agreement or applicable Delaware law in the event of a conversion, merger, or consolidation, a sale of substantially all of our assets, or any other similar transaction or event

We will continue as a limited liability company until dissolved under the terms of our operating agreement. We will dissolve upon:

Upon a dissolution under the last clause above, the holders of a unit majority may also elect, within specific time limitations, to continue our business on the same terms and conditions described in our operating agreement by appointing as a successor managing member an entity approved by a unit majority, subject to the receipt by us of an opinion of counsel to the effect that the action would not result in the loss of limited liability under Delaware law of any member.

If we dissolve in accordance with our operating agreement, unless our business is continued, the liquidator authorized to wind up our affairs will, acting with all of the powers of our managing member that are necessary or appropriate, liquidate our assets. The liquidator will first apply the proceeds of liquidation to the payment of our creditors and, thereafter, holders of our common units would be entitled to share ratably in the distribution of any remaining proceeds.

Our managing member may withdraw as managing member without first obtaining approval of our unitholders by giving 90 days' written notice, and that withdrawal will not constitute a violation of our operating agreement. In addition, our operating agreement permits our managing member, in some instances, to sell or otherwise transfer all of its managing member interest in us without the approval of the unitholders.

Upon withdrawal of our managing member under any circumstances, other than as a result of a transfer by our managing member of all or a part of its managing member interest in us, the holders of a unit majority may select a successor to that withdrawing managing member. If a successor is not elected, or is elected but an opinion of counsel regarding limited liability matters cannot be obtained, we will be dissolved, wound up, and liquidated, unless within a specified period after that withdrawal, the holders of a unit majority agree in writing to continue our business and to appoint a successor managing member. See "—Dissolution."

Our managing member may not be removed unless (i) that removal is approved by the vote of the holders of not less than 66²/3% of the outstanding ENLC Units, including ENLC Units held by our managing member and its affiliates, and (ii) we have received an opinion of counsel regarding limited liability matters. Any removal of our managing member is also subject to the approval of a successor managing member by the vote of a unit majority, including ENLC Units held by our managing member

and its affiliates. The ownership of more than 33¹/3% of the voting power of the ENLC Units by our managing member and its affiliates gives them the ability to prevent their removal as our managing member. As of April 3, 2019, our managing member and its affiliates owned approximately 41.1% of the voting power of the ENLC Units.

In the event of the removal of our managing member under circumstances where cause exists or withdrawal of our managing member where that withdrawal violates our operating agreement, a successor managing member will have the option to purchase the managing member interest of the departing managing member and its affiliates for a cash payment equal to the fair market value of those interests. Under all other circumstances where the managing member withdraws or is removed by the members, the departing managing member will have the option to require the successor managing member to purchase the managing member interest of the departing managing member and its affiliates for fair market value. In each case, this fair market value will be determined by agreement between the departing managing member and the successor managing member. If no agreement is reached, an independent investment banking firm or other independent expert selected by the departing managing member and the successor managing member will determine the fair market value. Or, if the departing managing member and the successor managing member cannot agree upon an expert, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.

If the option described above is not exercised by either the departing managing member or the successor managing member, the departing managing member's managing member interest will automatically convert into common units equal to the fair market value of those interests as determined by an investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

In addition, we will be required to reimburse the departing managing member for all amounts due the departing managing member, including, without limitation, all employee-related liabilities, including severance liabilities, incurred as a result of the termination of any employees employed for our benefit by the departing managing member or its affiliates.

At any time, our managing member may transfer all or any part of its managing member interest in us to another person without the approval of any other member. As a condition of this transfer, the transferee must, among other things, assume the rights and duties of our managing member, agree to be bound by the provisions of our operating agreement, and furnish an opinion of counsel regarding limited liability matters.

At any time, the owner of our managing member may sell or transfer all or part of its ownership interests in our managing member to an affiliate or third party without the approval of our unitholders.

Our operating agreement contains specific provisions that are intended to discourage a person or group from attempting to remove our managing member or from otherwise changing our management. If any person or group, other than our managing member and its affiliates, acquires beneficial ownership of 20% or more of any class of ENLC Units, that person or group loses voting rights on all of its ENLC Units. This loss of voting rights does not apply to any person or group that acquires the ENLC Units from our managing member or its affiliates and any transferees of that person or group approved by our managing member or to any person or group who acquires the common units with the prior approval of our board of directors.

If at any time our managing member and its affiliates own more than 90% of the then-issued and outstanding membership interests of any class, our managing member will have the right, which it may assign in whole or in part to any of its affiliates or to our managing member, to acquire all, but not less than all, of the membership interests of the class held by unaffiliated persons, as of a record date to be selected by our managing member, on at least 10, but not more than 60, days' notice. The purchase price in the event of this purchase is the greater of:

As a result of our managing member's right to purchase outstanding membership interests, a holder of membership interests may have his membership interests purchased at an undesirable time or at a price that may be lower than market prices at various times prior to such purchase or lower than a unitholder may anticipate the market price to be in the future. The tax consequences to a holder of ENLC Units of the exercise of this call right are the same as a sale by that unitholder of its ENLC Units in the market.

Except as described below regarding a person or group owning 20% or more of any class of ENLC Units, record holders of ENLC Units on the record date will be entitled to notice of, and to vote at, meetings of our members and to act upon matters for which approvals may be solicited.

Any action that is required or permitted to be taken by the unitholders may be taken either at a meeting of the unitholders or, if authorized by the managing member, without a meeting if consents in writing describing the action so taken are signed by holders of the number of ENLC Units necessary to authorize or take that action at a meeting. Meetings of the unitholders may be called by our managing member 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 an ENLC Unit will have a vote according to such holder's percentage interest in us, although additional membership interests having special voting rights could be issued. See "—Issuance of Additional Interests." However, if at any time any person or group, other than our managing member and its affiliates, or a direct or subsequently approved transferee of our managing member or its affiliates and purchasers specifically approved by our managing member, acquires, in the aggregate, beneficial ownership of 20% or more of any class of units, that person or group will lose voting rights on all of its ENLC Units, and the ENLC 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. Our common units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and his nominee provides otherwise.

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

By transfer of our common units in accordance with our operating agreement, each transferee of our common units shall be admitted as a member with respect to our common units transferred when such transfer and admission are reflected in our books and records. Except as described under "—Limited Liability," our common units will be fully paid, and unitholders will not be required to make additional contributions.

Section 18-108 of the DLLCA, as amended, empowers a Delaware limited liability company to indemnify and hold harmless any member or manager or other person from and against all claims and demands whatsoever. Our operating agreement provides that we will indemnify the following persons, to the fullest extent permitted by the law, from and against all losses, claims, damages, or similar events:

unless there has been a final and non-appealable judgment by a court of competent jurisdiction that, in respect of the matter for which such persons are seeking indemnification, those persons acted in bad faith, or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that their conduct was unlawful.

Any indemnification under these provisions will only be out of our assets. Unless our managing member otherwise agrees, it will not be personally liable for, or have any obligation to contribute or lend funds or assets to us to enable us to effectuate, 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 our operating agreement.

We have entered into indemnification agreements with each of the directors and executive officers of our managing member. Under the terms of these indemnification agreements, we agree to indemnify and hold each indemnitee harmless from and against any and all losses, claims, damages, liabilities, judgments, fines, taxes (including ERISA excise taxes), penalties (whether civil, criminal, or other), interest, assessments, amounts paid or payable in settlements, or other amounts and any and all "expenses" (as defined in the indemnification agreements) arising from any and all threatened, pending, or completed claims, demands, actions, suits, proceedings, or alternative dispute mechanisms, whether civil, criminal, administrative, arbitrative, investigative, or otherwise, whether made pursuant to federal, state, or local law, whether formal or informal, and including appeals, in each case, which the indemnitee may be involved, or is threatened to be involved, as a party, a witness, or otherwise, including any inquiries, hearings, or investigations that the indemnitee determines might lead to the

institution of any proceeding, related to the fact that indemnitee is or was a director, manager, or officer of us or our managing member, or is or was serving at the request of us or our managing member, each as applicable, as a manager, managing member, general partner, director, officer, fiduciary, trustee, or agent of any other entity, organization, or person of any nature. We have also agreed to advance the expenses of an indemnitee relating to the foregoing. To the extent that a change in the laws of the State of Delaware permits greater indemnification under any statute, agreement, organizational document, or governing document than would be afforded under the indemnification agreements as of the date of the indemnification agreements, the indemnitee shall enjoy the greater benefits so afforded by such change.

Our operating agreement requires us to reimburse our managing member on a monthly basis for all direct and indirect expenses it incurs or payments it makes on our behalf and all other expenses allocable to us or otherwise incurred by our managing member in connection with operating our business. Our operating agreement does not set a limit on the amount of expenses for which our managing member and its affiliates may be reimbursed. These expenses include salary, bonus, incentive compensation, and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our managing member by its affiliates. Our managing member is entitled to determine the expenses that are allocable to us.

Our managing member is required to keep appropriate books of our business at its principal offices. These books will be maintained for both tax and financial reporting purposes on an accrual basis in accordance with generally acceptable accounting principles (GAAP). For tax and fiscal reporting purposes, our fiscal year is the calendar year.

We will furnish or make available to record holders of our common units, within 105 days after the close of each fiscal year, an annual report containing audited consolidated financial statements and a report on those consolidated financial statements by its independent public accountants. Except for its fourth quarter, we will also furnish or make available summary financial information within 50 days after the close of each quarter. We will be deemed to have made any such report available if we file such report with the SEC via its Electronic Data Gathering, Analysis and Retrieval system or make the report available on a publicly available website which we maintain.

Our operating agreement provides that a member can, for a purpose reasonably related to such member's interest as a member, upon reasonable written demand stating the purpose of such demand and at such member's own expense, have furnished to such member:

Under our operating agreement, however, each of our members and other persons who acquire our membership interests, do not have rights to receive information from us or any of the persons we

indemnify as described above under "—Indemnification" for the purpose of determining whether to pursue litigation or assist in pending litigation against us or those indemnified persons relating to its affairs, except pursuant to the applicable rules of discovery relating to the litigation commenced by the person seeking information.

Our managing member may, and intends to, keep confidential from our members trade secrets or other information the disclosure of which our managing member determines is not in our best interests, could damage us or that we are required by law or by agreements with third parties to keep confidential. Our operating agreement limits the right to information that a member would otherwise have under Delaware law.

Conflicts of interest exist and may arise in the future as a result of the relationships between our managing member or its affiliates, on the one hand, and us, our members, or our subsidiaries, on the other hand. Our operating agreement specifically defines the remedies available to our unitholders for actions taken that, without these defined liability standards, might constitute breaches of fiduciary duty under applicable Delaware law. The DLLCA provides that Delaware limited liability companies may, in their operating agreements, expand, restrict, or eliminate the fiduciary duties otherwise owed by the manager to the members and the company, but such agreements may not eliminate the implied contractual covenant of good faith and fair dealing.

Whenever a conflict arises between our managing member or its affiliates, on the one hand, and us, our members, or our subsidiaries, on the other hand, the resolution or course of action in respect of such conflict of interest shall be permitted and conclusively deemed approved by us and all of our members and shall not constitute a breach of our operating agreement, of any agreement contemplated thereby, or of any duty, if the resolution or course of action in respect of such conflict of interest is:

Our managing member may, but is not required to, seek the approval of such resolutions or courses of action from the conflicts committee of our board of directors or from the holders of a majority of the outstanding common units as described above. Unless the resolution of a conflict is specifically provided for in our operating agreement, our board of directors or the conflicts committee of our board of directors may consider any factors they determine in good faith to consider when resolving a conflict. An independent third party is not required to evaluate the resolution. Under our operating agreement, a determination, other action, or failure to act by our managing member, our board of directors, or any committee thereof (including the conflicts committee) will be deemed to be in "good faith" if our managing member, our board of directors, or any committee thereof (including the conflicts committee) subjectively believed such determination, other action or failure to act was in, or not opposed to, our best interests. In any proceeding brought by or on behalf of us or any of our unitholders, the person bringing or prosecuting such proceeding will have the burden of proving that such determination, other action, or failure to act was not in good faith.

Duties owed to unitholders by our managing member are prescribed by law and in our operating agreement. The DLLCA provides that Delaware limited liability companies may, in their operating agreements, expand, restrict, or eliminate the fiduciary duties otherwise owed by our managing member to members and us.

Our operating agreement contains various provisions that eliminate and replace the fiduciary duties that might otherwise be owed by our managing member. These provisions have been negotiated to allow our managing member or its affiliates to engage in transactions with us that otherwise might be prohibited by state law fiduciary standards and to take into account the interests of other parties in addition to our interests when resolving conflicts of interest. Without these modifications, our managing member's ability to make decisions involving conflicts of interest would be restricted. Replacing the fiduciary duty standards in this manner benefits our managing member by enabling it to take into consideration all parties involved in the proposed action. Replacing the fiduciary duty standards also strengthens the ability of our managing member to attract and retain experienced and capable directors. Replacing the fiduciary duty standards represents a detriment to our public unitholders because it restricts the remedies available to the public unitholders for actions that, without those limitations, might constitute breaches of fiduciary duty, as described below, and permits our managing member to take into account the interests of third parties in addition to our interests when resolving conflicts of interests.

The following is a summary of the fiduciary duties imposed on managers of a limited liability company by the DLLCA in the absence of operating agreement provisions to the contrary, the contractual duties of our managing member contained in our operating agreement that replace the fiduciary duties that would otherwise be imposed by Delaware laws on our managing member and the rights and remedies of its unitholders with respect to these contractual duties:


State law fiduciary 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 an operating agreement providing otherwise, would generally require a managing member to act for the company 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 an operating agreement providing otherwise, would generally require that any action taken or transaction engaged in be entirely fair to the company.
Operating agreement modified standards		Our operating agreement contains provisions that waive or consent to conduct by our managing member and its affiliates that might otherwise raise issues as to compliance with fiduciary duties or applicable law. For example, our operating agreement provides that when our managing member is acting in its capacity as our managing member, 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 (other than the implied contractual covenant of good faith and fair dealing). In addition, when our managing member is acting in its individual capacity, as opposed to in its capacity as our managing member, it may act without any fiduciary obligation to us or the unitholders whatsoever. These standards replace the obligations that our managing member would otherwise be held to.


		If our managing member does not obtain approval from the conflicts committee of the board of directors of our managing member or the holders of our common units, excluding any units owned by our managing member or its affiliates, and our board of directors approves the resolution or course of action taken with respect to the conflict of interest, then it will be presumed that, in making its decision, our board of directors, which may include board members affected by the conflict of interest, acted in good faith, and in any proceeding brought by or on behalf of any member or us, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. These standards replace the obligations that our managing member would otherwise be held to.
Rights and remedies of unitholders		The DLLCA generally provides that a member may institute legal action on behalf of the company to recover damages from a third party where a manager has refused to institute the action or where an effort to cause a manager to do so is not likely to succeed. These actions include actions against a manager for breach of its duties or of our operating agreement. In addition, the statutory or case law of some jurisdictions may permit a member to institute legal action on behalf of himself and all other similarly situated members to recover damages from a manager for violations of its fiduciary duties to the members.
Operating agreement modified standards		The DLLCA provides that, unless otherwise provided in an operating agreement, a member or other person shall not be liable to a limited liability company or to another member or to another person that is a party to or is otherwise bound by an operating agreement for breach of fiduciary duty for the member's or other person's good faith reliance on the provisions of the operating agreement. Under our operating agreement, to the extent that, at law or in equity an indemnitee has duties (including fiduciary duties) and liabilities relating thereto to us or to our members, our managing member, and any other indemnitee acting in connection with its business or affairs shall not be liable to us or to any member for its good faith reliance on the provisions of our operating agreement.

By acquiring our common units, each new holder of our common units automatically agrees to be bound by the provisions in our operating agreement, including the provisions discussed above. This is in accordance with the policy of the DLLCA favoring the principle of freedom of contract and the enforceability of operating agreements. The failure of a member to sign an operating agreement does not render the operating agreement unenforceable against that person.

Under our operating agreement, we must indemnify our managing member and its officers, directors, managers, and certain other specified persons, to the fullest extent permitted by law, against liabilities, costs, and expenses incurred by our managing member or these other persons. We must provide this indemnification unless there has been a final and non-appealable judgment by a court of competent jurisdiction determining that these persons acted in bad faith, or engaged in fraud or willful misconduct. We must also provide this indemnification for criminal proceedings unless our managing

member or these other persons acted with knowledge that their conduct was unlawful. Thus, our managing member could be indemnified for its negligent acts if it meets the requirements set forth above. To the extent these provisions purport to include indemnification for liabilities arising under the Securities Act of 1933, as amended (the "Securities Act"), in the opinion of the SEC, such indemnification is contrary to public policy and, therefore, unenforceable. See "—Indemnification."

We make cash distributions, if any, to holders of our common units on a pro rata basis; provided, however, that, if ENLK fails to pay in full certain cash amounts with respect to quarterly distributions to the holder of the ENLK Series B Units when due, then from and after the first date of such failure and continuing until such failure is cured by payment in full in cash of all such cash arrearages, we are not permitted to, and will not, declare or make any distributions in respect of our common units and any other class of membership interests that, with respect to distributions, ranks junior to the ENLK Series B Units.

Unless restricted by the terms of the agreements governing our outstanding indebtedness, we intend to pay distributions to holders of our common units on a quarterly basis from our available cash less reserves for expenses, future distributions, and other uses of cash, including:

Our ability to pay distributions is limited by the DLLCA, which provides that a limited liability company may not pay distributions if, after giving effect to the distribution, the company's liabilities would exceed the fair value of its assets. While our ownership of equity interests in ENLK are included in our calculation of net assets, the value of these assets may decline to a level where our liabilities would exceed the fair value of our assets if we were to pay distributions, thus prohibiting us from paying distributions under Delaware law.

The following discussion summarizes the material U.S. federal income tax consequences, and, in the case of a non-U.S. holder (as defined below), material U.S. federal estate tax consequences, related to the purchase, ownership and disposition of our common units by a taxpayer that holds our common units as a "capital asset" (generally, property held for investment). This discussion is based on the provisions of the Internal Revenue Code of 1986, as amended (the "Code"), U.S. Treasury regulations and administrative rulings and judicial decisions, all as in effect on the date hereof, and all of which are subject to change, possibly with retroactive effect. We have not sought any ruling from the Internal Revenue Service (the "IRS") with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

Legal conclusions contained in this section, unless otherwise noted, are the opinion of Baker Botts L.L.P. This discussion does not address all aspects of U.S. federal income taxation (and, in the case of a non-U.S. holder, estate taxation) or the tax considerations arising under the laws of any non-U.S., state, or local jurisdiction, or under U.S. federal gift tax laws. In addition, this discussion does not address tax considerations applicable to investors that may be subject to special treatment under the U.S. federal income tax laws, such as (without limitation):

If a partnership (or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common units, the tax treatment of a partner in the partnership generally will depend upon the status of the partner, certain determinations made at the partner level and the activities of the partnership. Accordingly, we urge partners of a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) investing in our common units to consult their tax advisors regarding the U.S. federal income tax considerations of the purchase, ownership, and disposition of our common units by such partnership.

YOU ARE ENCOURAGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME AND ESTATE TAX LAWS TO YOUR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF OUR COMMON UNITS ARISING UNDER THE U.S. FEDERAL GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Although we are a Delaware limited liability company, we have elected to be treated as a corporation for U.S. federal income tax purposes. As a result, we are subject to tax as a corporation and distributions on the common units will be treated as distributions on corporate stock for federal income tax purposes. No Schedule K-1 will be issued with respect to the common units, but instead holders of common units will receive a Form 1099 from us with respect to distributions received on the common units.

The discussion in this section is addressed to holders of our common units that are U.S. holders for U.S. federal income tax purposes. A U.S. holder for purposes of this discussion is a beneficial owner of our common units that is, for U.S. federal income tax purposes:

Distributions with respect to our common units will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent that the amount of a distribution with respect to our common units exceeds our current and accumulated earnings and profits, such distribution will be treated first as a tax-free return of capital to the extent of the U.S. holder's adjusted tax basis in such common units, which reduces such basis dollar-for-dollar, and thereafter as capital gain. Such gain will be long-term capital gain provided that the U.S. holder has held such common units for more than

one year as of the time of the distribution. Non-corporate holders that receive distributions on our common units that are treated as dividends for U.S. federal income tax purposes generally will be subject to U.S. federal income tax on such dividends at a reduced maximum tax rate that is currently 20% provided certain holding period requirements are met.

Prospective investors in our common units are encouraged to consult their tax advisors as to the tax consequences of receiving distributions on our common units, including, in the case of prospective corporate investors, the ability to claim the corporate dividends received deduction with respect to such distributions.

A U.S. holder generally will recognize capital gain or loss on a sale, exchange or other taxable disposition of our common units equal to the difference, if any, between the amount realized upon the disposition of such common units and the U.S. holder's adjusted tax basis in those common units. A U.S. holder's tax basis in the common units generally will be equal to the amount paid for such common units reduced (but not below zero) by distributions received on such common units that are not treated as dividends for U.S. federal income tax purposes. Such capital gain or loss generally will be long-term capital gain or loss if the U.S. holder's holding period for the common units sold or disposed of is more than one year. Long-term capital gains of individuals generally are subject to a reduced maximum U.S. federal income tax rate that is currently 20%. The deductibility of net capital losses is subject to limitations.

Information returns generally will be filed with the IRS with respect to distributions on, and the proceeds from a disposition of, our common units held by a U.S. holder, unless the U.S. holder is a recipient that is exempt from information reporting (such as a corporation) and, if requested, establishes, in the manner prescribed by law, such exemption. A U.S. holder may be subject to backup withholding on distributions with respect to our common units and on the proceeds of a disposition of our common units unless such U.S. holder furnishes the applicable withholding agent with a taxpayer identification number, certified under penalties of perjury, and certain other information, or otherwise establishes, in the manner prescribed by law, an exemption from backup withholding. Penalties apply for failure to furnish correct information and for failure to include reportable payments in income.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be creditable against a U.S. holder's U.S. federal income tax liability, and the U.S. holder may be entitled to a refund, provided the U.S. holder timely furnishes the required information to the IRS. U.S. holders are urged to consult their own tax advisors regarding the application of the backup withholding rules to their particular circumstances and the availability of, and procedure for, obtaining an exemption from backup withholding.

Certain U.S. holders that are individuals, trusts or estates will be subject to an additional 3.8% Medicare tax on unearned income, which generally will include dividends received on and gain recognized with respect to the sale or other taxable disposition of our common units. For individual U.S. holders, the additional Medicare tax applies to the lesser of (i) "net investment income" and (ii) the excess of "modified adjusted gross income" over $200,000 ($250,000 if married and filing jointly or $125,000 if married and filing separately). "Net investment income" generally equals a U.S. holder's gross investment income reduced by the deductions that are allocable to such income. Investment income generally includes passive income such as interest, dividends, annuities, royalties, rents, and capital gains. U.S. holders are urged to consult their own tax advisors regarding the application of this additional Medicare tax to their particular circumstances.

The discussion in this section applies only to holders of our common units that are non-U.S. holders. For purposes of this discussion, a non-U.S. holder is a beneficial owner of our common units that is an individual, corporation, estate or trust for U.S. federal income tax purposes and, in each case, is not a U.S. holder.

Distributions with respect to our common units will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent a distribution exceeds our current and accumulated earnings and profits, such distribution will reduce the non-U.S. holder's adjusted tax basis in its common units (but not below zero). The amount of any such distribution in excess of the non-U.S. holder's adjusted tax basis in its common units will be treated as gain from the sale of such common units and will have the tax consequences described below under "—Sale, Exchange or Other Taxable Disposition of Common Units."

Subject to the discussion below on effectively connected income and under "—Backup Withholding and Information Reporting" and "Material United States Federal Income Tax Considerations—Additional Withholding Requirements," a distribution treated as a dividend paid to a non-U.S. holder on our common units generally will be subject to U.S. federal withholding tax at a rate of 30%, or such lower rate as may be specified by an applicable income tax treaty. To receive the benefit of a reduced treaty rate, a non-U.S. holder must satisfy applicable certification requirements (generally by providing the withholding agent with a properly completed and executed IRS Form W-8BEN or IRS Form W-8BEN-E (as applicable), or other appropriate form, certifying qualification for the reduced rate).

Non-U.S. holders are encouraged to consult their tax advisors regarding the withholding rules applicable to distributions on our common units, the requirements for claiming treaty benefits, and any procedures required to obtain a refund of any overwithheld amounts.

Distributions treated as dividends that are paid to a non-U.S. holder and are effectively connected with a trade or business conducted by the non-U.S. holder in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment maintained by the non-U.S. holder in the United States) generally will be taxed on a net income basis at the rates and in the manner generally applicable to U.S. persons (as defined under the Code). Effectively connected dividend income will not be subject to the U.S. federal withholding tax described above if the non-U.S. holder satisfies certain certification requirements by providing to the withholding agent a properly completed and executed IRS Form W-8ECI (or appropriate substitute or successor form) certifying eligibility for the exemption. If the non-U.S. holder is a corporation, that portion of the corporation's earnings and profits for the taxable year, as adjusted for certain items, that is effectively connected with its U.S. trade or business (and, if required by applicable income tax treaty, is attributable to a permanent establishment maintained by the corporate non-U.S. holder in the United States) may also be subject to a "branch profits tax" at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

Subject to the discussion below under "—Backup Withholding and Information Reporting" and "Material United States Federal Income Tax Considerations—Additional Withholding Requirements," a

non-U.S. holder generally will not be subject to U.S. federal income tax or withholding tax on any gain realized upon the sale or other disposition of our common units unless:

A non-U.S. holder described in the first bullet point above will be subject to tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on the amount of such gain (which generally may be offset by U.S. source capital losses).

A non-U.S. holder whose gain is described in the second bullet point above will be subject to U.S. federal income tax on any gain recognized on a net income basis at the same graduated rates generally applicable to U.S. persons unless an applicable income tax treaty provides otherwise. Corporate non-U.S. holders may also be subject to a branch profits tax equal to 30% (or such lower rate as may be specified by an applicable income tax treaty) of their effectively connected earnings and profits attributable to such gain, as adjusted for certain items.

Generally, a corporation is a USRPHC if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business. We believe that we currently are, and expect to remain for the foreseeable future, a USRPHC. However, as long as our common units are "regularly traded on an established securities market," a non-U.S. holder will not be subject to U.S. federal income tax or withholding tax upon the disposition of our common units as a result of our status as a USRPHC unless the non-U.S. holder directly, indirectly or constructively owns, or owned at any time during the five-year period ending on the date of the disposition or, if shorter, the non-U.S. holder's holding period for the common units, more than 5% of our common units. If a non-U.S. holder's ownership of our common units has exceeded the 5% threshold specified in the preceding sentence, such non-U.S. holder (or, if our common units were not considered to be regularly traded on an established securities market during the calendar year in which the relevant disposition occurs, any non-U.S. holder (regardless of the percentage of common units owned)) would be subject to U.S. federal income tax in the manner described in the preceding paragraph on the gain realized upon a taxable disposition of our common units, and U.S. federal withholding tax at a rate of 15% would apply to the gross proceeds from such disposition. Non-U.S. holders should consult their tax advisors with respect to the application of the foregoing rules to their ownership and disposition of our common units.

Our common units beneficially owned or treated as owned by an individual who is not a citizen or resident of the United States (as defined for U.S. federal estate tax purposes) at the time of death generally will be includable in the decedent's gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise, and therefore may be subject to U.S. federal estate tax.

Generally, we will report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such non-U.S. holder, the name and address of such non-U.S. holder, and the

amount, if any, of tax withheld with respect to those dividends. These information reporting requirements apply even if withholding was not required. Pursuant to tax treaties or other agreements, the IRS may make such reports available to tax authorities in the non-U.S. holder's country of residence.

Payments of dividends to a non-U.S. holder generally will not be subject to backup withholding if the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on a properly completed and executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form), provided that the withholding agent does not have actual knowledge, or reason to know, that the beneficial owner is a U.S. person that is not an exempt recipient.

Payments of the proceeds from a sale or other disposition by a non-U.S. holder of our common units effected by or through a U.S. office of a broker generally will be subject to information reporting and backup withholding (at the applicable rate) unless the non-U.S. holder establishes an exemption by properly certifying its non-U.S. status on a properly completed and executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) and certain other conditions are met or the non-U.S. holder otherwise establishes an exemption. Information reporting and backup withholding generally will not apply to any payment of the proceeds from a sale or other disposition of our common units effected outside the United States by a foreign office of a broker. However, unless such broker has documentary evidence in its records that the non-U.S. holder is not a U.S. person and certain other conditions are met, or the non-U.S. holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of our common units effected outside the United States by such a broker if it has certain relationships within the United States.

Backup withholding is not an additional tax. Rather, the U.S. income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained, provided that certain required information is timely furnished to the IRS.

Sections 1471 through 1474 of the Code and the Treasury regulations and administrative guidance issued thereunder generally impose a 30% withholding tax on any dividends paid on our common units if paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless (i) in the case of a foreign financial institution, such institution enters into an agreement with the U.S. government to withhold on certain payments, and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners); (ii) in the case of a nonfinancial foreign entity, such entity certifies that it does not have any "substantial United States owners" (as defined in the Code) or furnishes the applicable withholding agent with a certification (generally on an IRS Form W-8BEN-E) identifying each direct and indirect substantial United States owner of the entity; or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as an IRS Form W-8BEN-E). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing these rules may be subject to different rules. Under certain circumstances, a holder might be eligible for refunds or credits of such taxes.

Prospective purchasers of our common units are urged to consult their own tax advisors with respect to the tax consequences of these withholding provisions.

THE PRECEDING DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. INVESTORS CONSIDERING THE PURCHASE OF OUR COMMON UNITS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME AND ESTATE TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE APPLICABILITY AND EFFECT OF STATE, LOCAL OR FOREIGN TAX LAWS AND TREATIES.

We may sell the securities being offered hereby in and outside the U.S. (1) through underwriters or underwriting syndicates led by one or more managing underwriters, (2) to or through brokers or dealers, (3) to or through agents, (4) directly to one or more purchasers, including our affiliates, (5) pursuant to delayed delivery contracts or forward contracts, or (6) through a combination of any of these methods.

The prospectus supplement will set forth the terms of the offering and the method of distribution and will include the following information:

If we use underwriters in the sale of securities, we will execute an underwriting agreement with the underwriter at the time of sale and we will provide the name of any underwriter in the prospectus supplement that the underwriter will use to make resales of securities to the public. The underwriters will acquire the securities for their own account, and the underwriters may resell the securities 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. The obligations of the underwriters to purchase the securities will be subject to conditions, and any underwritten offering may be on a firm commitment basis. The underwriters may change from time to time any public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

If we use dealers in the sale of securities, we will 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 those securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

We may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, 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.

We may sell the securities directly. In that event, no underwriters or agents would be involved. We may use electronic media, including the Internet, to sell offered securities directly.

If we so indicate in the prospectus supplement, we may authorize agents, underwriters, or dealers to solicit offers to purchase securities from us at the public offering price set forth in the prospectus under delayed delivery or forward contracts. These contracts would provide for payment and delivery on a specified date in the future at prices determined as described in the prospectus supplement. The prospectus supplement would describe the commission payable for solicitation of those contracts.

We may offer and sell any of the securities in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to the remarketing firm in the prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties in these sale transactions will be underwriters and, if not identified in this prospectus, will be identified in the applicable prospectus supplement or in a post-effective amendment to the registration statement of which this prospectus forms a part. In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

In connection with the sale of the securities, underwriters, dealers, or agents may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from securities purchasers for whom they may act as agent. Underwriters may sell the securities to or through dealers, and the dealers may receive compensation in the form of discounts, concessions, or commissions from the underwriters or commissions from the purchasers for whom they may act as agent. We will provide in the applicable prospectus supplement information regarding any underwriting discounts or other compensation that we pay to underwriters or agents in connection with the securities offering, and any discounts, concessions, or commissions which underwriters allow to dealers.

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

Other than the common units, which are listed on the New York Stock Exchange, each series of offered securities will have no established trading market. We may elect to list any series of offered securities on an exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a series of offered securities. However, they will not be obligated to do so and may discontinue market making at any time without notice. We cannot assure you as to the liquidity of, or the trading market for, any of our offered securities.

In connection with an offering, certain persons participating in the offering may make a market in the securities or engage in transactions that stabilize, maintain, or otherwise affect the market price of the offered securities. This may include, among other transactions, over-allotments, or short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. As a result, the price of the securities may be higher than the price that might otherwise prevail in the open market. If these activities are commenced, these transactions may be discontinued at any time.

To the extent required, this prospectus may be amended or supplemented from time to time to describe a specific plan of distribution. The place and time of delivery for the securities in respect of which this prospectus is delivered are set forth in the accompanying prospectus supplement.

The validity of the securities offered in this prospectus will be passed upon for us by Baker Botts L.L.P., Dallas, Texas. If certain legal matters in connection with an offering of the securities made by this prospectus and a related prospectus supplement are passed on by counsel for the underwriters of such offering, that counsel will be named in the applicable prospectus supplement related to that offering.
