Summit Midstream Partners, LP

We are a growth-oriented limited partnership focused on owning and operating midstream energy infrastructure assets that are strategically located in the core producing areas of unconventional resource basins, primarily shale formations, in North America. We currently provide primarily fee-based natural gas gathering and compression services in four unconventional resource basins: (i) the Piceance Basin, which includes the Mesaverde formation and the Mancos and Niobrara shale formations in western Colorado; (ii) the Fort Worth Basin, which includes the Barnett Shale formation in north-central Texas; (iii) the Williston Basin, which includes the Bakken and Three Forks shale formations in northwestern North Dakota; and (iv) the Appalachian Basin, which includes the Marcellus Shale formation in northern West Virginia.

We generate a substantial majority of our revenue under long-term, primarily fee-based natural gas gathering agreements. Substantially all of our gas gathering agreements are underpinned by areas of mutual interest, or AMIs, and minimum volume commitments, or MVCs. Our AMIs cover approximately one million acres in the aggregate, have original terms that range from five years to 25 years, and provide that any natural gas producing wells drilled by our customers within such AMIs will be shipped on our gathering systems. Our MVCs, which totaled 3.2 Tcf at September 30, 2013 and average approximately 881 MMcf/d through 2020, are designed to ensure that we will generate a certain amount of revenue from each customer over the life of the respective gas gathering agreement, whether by collecting gathering fees on actual throughput or from cash payments to cover any MVC shortfall. Our MVCs have remaining terms that range from three to 13 years and, as of September 30, 2013, had a weighted-average remaining life of 10.1 years, assuming minimum

throughput volumes for the remainder of their respective terms. We believe that the fee-based nature of these agreements enhances the stability of our cash flows by limiting our direct commodity price exposure.

Our Midstream Assets

Grand River system. The Grand River system is located in the Piceance Basin in western Colorado and currently serves producers targeting the liquids-rich Mesaverde formation. It is optimally located for expansion to gather production from the emerging Mancos and Niobrara shale formations underlying the Mesaverde formation. We have constructed a new medium-pressure gathering system to service future higher pressure natural gas production from the Mancos and Niobrara shale formations.

DFW Midstream system. The DFW Midstream system is primarily located in southeastern Tarrant County, the largest natural gas producing county in Texas. We consider this area to be the core of the core of the Barnett Shale because of the quality of the geology and the high production profile of the wells drilled to date. We believe that the AMIs underpinning our system are substantially undeveloped compared with other areas in the Barnett Shale due to the historical lack of gathering infrastructure. Our AMIs and our system footprint provide us with a competitive advantage to add additional producers and incremental volumes in this core area of the Barnett Shale at a competitive capital cost.

Bison Midstream system. The Bison Midstream system is located in the Williston Basin in northwestern North Dakota and serves producers that are targeting the Bakken and Three Forks shale formations. These formations are primarily targeted for crude oil production and producer drilling decisions are based largely on the prevailing price of crude oil. The Bison Midstream system gathers and compresses associated natural gas that exists in the crude oil production stream. We believe that the pace of drilling activity and thus, natural gas volume throughput on the Bison Midstream system, will primarily depend on the price of crude oil which provides diversity of commodity price exposure for us relative to our other natural gas midstream operations.

Mountaineer Midstream system. The Mountaineer Midstream system is located in the Appalachian Basin and currently serves Antero Resources Corporation, or Antero, which is targeting liquids-rich natural gas production from the Marcellus Shale formation in Harrison and Doddridge counties in West Virginia. The Mountaineer Midstream system serves as a critical inlet to MarkWest's Sherwood Processing Complex, the primary destination for liquids-rich natural gas in northern West Virginia. Throughput capacity on the Mountaineer Midstream system is currently being expanded from 550 MMcf/d to 1,050 MMcf/d to support Antero's current and future anticipated drilling activities in this prolific region of the Marcellus Shale play.

The following table provides information regarding our gathering assets as of, or for the nine months ended, September 30 for the periods indicated:

	Grand River				DFW Midstream				Bison Midstream				Mountaineer Midstream

	2013		2012		2013		2012		2013		2012		2013		2012
Miles of pipeline (as of September 30)		301		282		119		110		330		*		41		*
Aggregate average throughput (for the nine months ended September 30) (MMcf/d)		502		585		398		344		14		*		50		*

*: Gathering system was not an asset of the Partnership during this period.

Our Business Strategies

Our principal business strategy is to increase the amount of cash distributions we make to our unitholders over time. Our plan for continuing to execute this strategy includes the following key components:

•: Pursuing accretive acquisition opportunities from Summit Investments. We intend to pursue opportunities to expand our asset base by acquiring midstream assets owned and operated by Summit Investments. In addition to its significant ownership interest in us, Summit Investments also owns and operates, and also seeks to acquire and develop additional, crude oil, natural gas and water-related midstream assets in service and under development in geographic areas in which we currently operate as well as in geographic areas outside of our current operations.
•: Diversifying our asset base by expanding our midstream service offerings and exploring acquisition and development opportunities in various geographic areas. While our natural gas gathering operations in the Piceance Basin and in the Barnett, Bakken and Marcellus shale plays currently represent our core business, we intend to diversify into other midstream services such as natural gas processing and crude oil gathering, through both greenfield development projects and acquisitions. We also intend to diversify our operations into other geographic regions.
•: Capitalizing on organic growth opportunities. We believe that our existing gathering systems provide us with significant organic expansion opportunities. We intend to continue to leverage our management team's expertise in constructing, developing and optimizing midstream infrastructure assets to grow our business through organic development projects that are designed to extend our geographic reach, diversify our customer base, expand our midstream service offerings, increase the number of our hydrocarbon receipt points and maximize volume throughput.
•: Increasing throughput volumes on our existing systems. We intend to continue to focus on maximizing the utilization of our assets by increasing volume throughput from existing customers and connecting new customers to our systems.
•: Maintaining our focus on fee-based revenue with minimal direct commodity price exposure. As we expand our business, we intend to maintain our focus on providing midstream energy services under fee-based agreements. Our midstream services are primarily provided under long-term, fee-based contracts with original terms ranging from five years to 25 years. We believe that our focus on fee-based revenues with minimal direct commodity price exposure is essential to maintaining stable cash flows.
•: Partnering with producers to provide midstream services for their development projects in high-growth, unconventional resource plays. We seek to promote commercial relationships with established and well-capitalized producers, who are willing to serve as anchor customers and provide long-term MVCs and AMIs. We will continue to pursue partnership opportunities with established producers to develop new infrastructure in unconventional resource basins that we believe will complement our existing midstream assets or enhance our overall business by facilitating our entry into new basins. These opportunities generally consist of a strategic acreage position in an unconventional resource play that is well-positioned for accelerated production but has limited existing midstream energy infrastructure to support such growth.

Our Competitive Strengths

We believe that we will be able to continue to execute the components of our principal business strategy successfully because of the following competitive strengths:

•: Strategically located assets in core areas of prolific unconventional basins supported by existing partnerships with large producers. Our existing assets are strategically positioned within the core areas of four established unconventional resource plays. The geologic formations in the basins served by our assets have either relatively low drilling and completion costs, highly economic production profiles, or a combination of both.
•: Fee-based revenues underpinned by long-term contracts with AMIs and MVCs. A substantial majority of our revenue for the nine months ended September 30, 2013 was generated under long-term, fee-based gas gathering agreements. We believe that long-term, fee-based gas gathering agreements enhance the stability of our cash flows by limiting our direct commodity price exposure.
•: Capital structure and financial flexibility. At February 15, 2014, we had $611.0 million of indebtedness and $389.0 million of borrowing capacity available to us under our amended and restated revolving credit facility (the "revolving credit facility").
•: Experienced management team with proven record of asset acquisition, construction, development, operation and integration expertise. Our executive management team has an average of 19 years of energy experience and a proven track record of identifying and consummating significant acquisitions in addition to partnering with major producers to construct and develop midstream energy infrastructure.
•: Relationships with large and committed financial sponsors. Our Sponsors, Energy Capital Partners and GE Energy Financial Services, are experienced energy investors with proven track records of making substantial, long-term investments in high-quality energy assets. We believe the relationship with our Sponsors is a competitive advantage, as they bring not only significant financial and management experience, but also numerous relationships throughout the energy industry that we believe will continue to benefit us as we seek to grow our business.

Our Sponsors

We were formed in 2009 by members of management and Energy Capital Partners, which together with its affiliated funds, is a private equity firm with over $11.0 billion in capital commitments that is focused on investing in North America's energy infrastructure. Energy Capital Partners has significant energy and financial expertise to complement its investment in us. As of December 31, 2013, Energy Capital Partners and its affiliated funds had 24 investment platforms with investments in the power generation, electric transmission, midstream natural gas and renewable sectors of the energy industry. In August 2011, Energy Capital Partners sold an interest in Summit Investments to GE Energy Financial Services. GE Energy Financial Services invests globally in essential, long-lived and capital-intensive energy assets. As of December 31, 2013, GE Energy Financial Services held approximately $18 billion in energy assets worldwide. GE Energy Financial Services has invested over $2 billion in midstream-related assets.

RISK FACTORS

Before deciding whether to participate in the exchange offer, you should consider carefully the risks and uncertainties described below and in Item 1A "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2012, in each case as updated by our subsequent Quarterly Reports on Form 10-Q and current reports on Form 8-K, together with all of the other information included in, or incorporated by reference into, this prospectus and, to the extent applicable, any subsequently filed reports when evaluating an investment in the new notes. If any of the risks discussed in the foregoing or in the documents incorporated by reference were to materialize, our business, financial condition, results of operations and cash flows could be materially adversely affected and you could lose all or part of your investment. Please also read "Forward-Looking Statements."

Risks Related to the Exchange Offer

If you fail to exchange old notes, existing transfer restrictions will remain in effect, and the market value of old notes may be adversely affected because they may be more difficult to sell.

If you fail to exchange old notes for new notes in the exchange offer, then you will continue to be subject to the existing transfer restrictions on the old notes. In general, the old notes may not be offered or sold unless they are registered or exempt from registration under the Securities Act and applicable state securities laws. Except in connection with this exchange offer or as required by the registration rights agreement, we do not intend to register resales of the old notes.

The tender of old notes in the exchange offer will reduce the principal amount of the currently outstanding old notes. Due to the corresponding reduction in liquidity, this may have an adverse effect upon, and increase the volatility of, the market price of any currently outstanding old notes that you continue to hold following the completion of the exchange offer.

Risks Related to Our Indebtedness and the Notes

We have a holding company structure in which our subsidiaries conduct our operations and own our operating assets.

We are a holding company, and our operating subsidiaries conduct all of our operations and own all of our operating assets. We have no significant assets other than our interest in our operating subsidiaries. As a result, our ability to make required payments on the notes depends on the performance of our operating 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, the revolving credit facility and applicable state limited liability company laws and other laws and regulations. If we are unable to obtain the funds necessary to pay the principal amount at maturity of the notes, or to repurchase the notes upon the occurrence of a change of control, we may be required to adopt one or more alternatives, such as a refinancing of the notes or a sale of assets. We may not be able to refinance the notes or sell assets on acceptable terms, or at all.

Our substantial debt could adversely affect our financial condition and prevent us from fulfilling our obligations under the notes.

We currently have a substantial amount of indebtedness. As of February 15, 2014, we had total debt of approximately $611.0 million, and we had $389.0 million of remaining borrowing capacity under the revolving credit facility. In addition, we may also incur additional indebtedness in the future. Specifically, our high level of debt could have important consequences to the holders of the notes, including the following:

•: making it more difficult for us to satisfy our obligations with respect to the notes and our other debt;

Table of Contents

•: limiting our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general partnership requirements;
•: requiring a substantial portion of our cash flows to be dedicated to debt service payments instead of other purposes;
•: increasing our vulnerability to general adverse economic and industry conditions;
•: limiting our flexibility in planning for and reacting to changes in our business and the industries in which we compete;
•: placing us at a disadvantage compared to other, less leveraged competitors; and
•: increasing our cost of borrowing.

Despite our current level of indebtedness, the indenture will permit us and our subsidiaries to incur substantially more indebtedness. This could further increase the risks associated with our substantial indebtedness.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of our indenture will not prohibit us or our subsidiaries from doing so. If we incur any additional indebtedness that ranks equally with the notes and the guarantees, the holders of that indebtedness will be entitled to share ratably with the notes offered hereby and the related guarantees 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 any proceeds paid to you. If new indebtedness is added to our current debt levels, the related risks that we and our subsidiaries now face could intensify.

We may be unable to service our indebtedness, including the notes.

Our ability to make scheduled payments on and to refinance our indebtedness, including the notes and our revolving credit facility, which matures in November 2018, depends on and is subject to our financial and operating performance, which in turn is affected by general and regional economic, financial, competitive, business and other factors beyond our control, including the availability of financing in the banking and capital markets. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to service our debt, including the notes, to refinance our debt or to fund our other liquidity needs. If we are unable to meet our debt obligations or to fund our other liquidity needs, we will need to restructure or refinance all or a portion of our debt, including the notes, which could cause us to default on our debt obligations and impair our liquidity. Any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants which could further restrict our business operations.

The notes and the guarantees will be unsecured and effectively subordinated to our and the guarantors' existing and future secured indebtedness.

The notes and the guarantees will be general unsecured obligations ranking effectively junior in right of payment to all of the Issuers' existing and future secured indebtedness and that of each guarantor (to the extent of the value of the assets securing such indebtedness). Additionally, the indenture governing the notes permits us to incur additional secured indebtedness in the future. As of February 15, 2014, we had $611.0 million of debt outstanding, $311.0 million of which was secured indebtedness under the revolving credit facility, and we had $389.0 million of remaining borrowing capacity under our revolving facility. In the event that either of the Issuers or a guarantor is declared bankrupt, becomes insolvent or is liquidated or reorganized, any indebtedness that ranks ahead of the notes and the guarantees will be entitled to be paid in full from the Issuers' assets or the assets of the

Table of Contents

guarantor, as applicable, before any payment may be made with respect to the notes or the affected guarantees. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events or in the event of the liquidation, dissolution, reorganization, bankruptcy or similar proceeding of the business of a non-guarantor subsidiary, as described below, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of the notes may receive less, ratably, than holders of secured indebtedness.

The notes will be structurally subordinated to all liabilities of any future non-guarantor subsidiaries.

The notes will be structurally subordinated to the indebtedness and other liabilities of any of our future subsidiaries that do not guarantee the notes. Any such non-guarantor subsidiaries are separate and distinct legal entities and will have no obligation, contingent or otherwise, to pay any amounts due pursuant to the notes, or to make any funds available therefor, whether by loans, distributions or other payments. Any right that we or the subsidiary guarantors have to receive any assets of any such non-guarantor subsidiaries upon the liquidation or reorganization of those subsidiaries, and the consequent rights of holders of notes to realize proceeds from the sale of any of those subsidiaries' assets, will be effectively subordinated to the claims of those subsidiaries' creditors, including trade creditors and holders of preferred equity interests of those subsidiaries. Accordingly, in the event of a bankruptcy, liquidation or reorganization of any such non-guarantor subsidiaries, these non-guarantor subsidiaries will pay the holders of their debts, holders of preferred equity interests and their trade creditors before they will be able to distribute any of their assets to us.

Certain restrictive covenants in the indenture governing the notes will be suspended if such notes achieve investment grade ratings.

Most of the restrictive covenants in the indenture governing the notes will not apply for so long as the notes achieve investment grade ratings from Moody's Investors Service, Inc. and Standard & Poor's Rating Services, and no default or event of default has occurred. If these restrictive covenants cease to apply, we may take actions, such as incurring additional debt or making certain dividends or distributions that would otherwise be prohibited under the indenture. Ratings are given by these rating agencies based upon analyses that include many subjective factors. We cannot assure you that the notes will achieve investment grade ratings, nor can we assure you that investment grade ratings, if granted, will reflect all of the factors that would be important to holders of the notes.

Our revolving credit facility and the indenture governing the notes impose significant operating and financial restrictions on us and our subsidiaries, which may prevent us from capitalizing on business opportunities.

Our revolving credit facility and the indenture governing the notes impose significant operating and financial restrictions on us. Our ability to borrow under our revolving credit facility is subject to compliance with certain financial covenants, including leverage and interest coverage ratios. These restrictions will limit our ability, among other things, to:

•: incur additional indebtedness or enter into sale and leaseback obligations or issue preferred securities;
•: make certain distributions or repurchase our equity interests or redeem or repurchase subordinated debt;
•: make certain capital expenditures;
•: make certain investments or other restricted payments;

Table of Contents

•: place restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us;
•: engage in transactions with affiliates;
•: consolidate, merge or transfer all or substantially all of our assets;
•: guarantee indebtedness;
•: create or incur liens;
•: create unrestricted subsidiaries; and
•: create additional non-guarantor subsidiaries.

Please read "Description of Other Indebtedness." As a result of these covenants and restrictions, we will be limited in how we conduct our business and we may be unable to raise additional debt or equity financing to compete effectively or to take advantage of new business opportunities. The terms of any future indebtedness we may incur could include more restrictive covenants. We cannot assure you that we will be able to maintain compliance with these covenants in the future and, if we fail to do so, that we will be able to obtain waivers from the lenders and/or amend the covenants. A breach of any of these covenants or other provisions in our debt agreements could result in an event of default, which if not cured or waived, could result in such debt becoming immediately due and payable. This, in turn, could cause our other debt to become due and payable as a result of cross-acceleration provisions contained in the agreements governing such other debt. In the event that some or all of our debt is accelerated and becomes immediately due and payable or we are unable to refinance our revolving credit facility at its maturity, we may not have the funds to repay, or the ability to refinance, such debt. Additionally, our revolving credit facility is secured by substantially all of our assets, and if we are unable to satisfy our obligations thereunder, the lenders could seek to foreclose on our assets.

Federal and state statutes allow courts, under specific circumstances, to void subsidiary guarantees and require noteholders to return payments received from subsidiary guarantors.

Under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a subsidiary's guarantee of the notes could be voided, or claims in respect of a 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 debt evidenced by its guarantee:

•: received less than reasonably equivalent value or fair consideration for the incurrence of such guarantee;
•: was insolvent or rendered insolvent by reason of such incurrence;
•: was engaged in a business or transaction for which the subsidiary guarantor's remaining assets constituted unreasonably small capital; or
•: intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature.

In addition, any payment by that subsidiary guarantor pursuant to its guarantee could be voided and required to be returned to the subsidiary guarantor, or to a fund for the benefit of our creditors or the creditors of the subsidiary guarantor.

Table of Contents

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 sum of its debts, including contingent liabilities, was greater than the fair saleable value of all of its assets;
•: if the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or
•: it could not pay its debts as they become due.

On the basis of historical financial information, recent operating history and other factors, we believe that each subsidiary guarantor, after giving effect to its guarantee of the notes, will not be insolvent, will not have unreasonably small capital for the business in which it is engaged and will not have incurred debts beyond its ability to pay such debts as they mature. We cannot assure you, however, as to what standard a court would apply in making these determinations or that a court would agree with our conclusions in this regard.

We may not have the funds necessary to finance the repurchase of the notes in connection with a change of control offer required by the indenture.

Upon the occurrence of specific kinds of change of control events, the indenture governing the notes will require the Issuers to make an offer to repurchase all such notes at 101% of the principal amount thereof, plus accrued and unpaid interest (and liquidated damages, if any) to the date of repurchase. However, it is possible that we will not have sufficient funds, or the ability to raise sufficient funds, at the time of the change of control to make the required repurchase of the notes. In addition, restrictions under the revolving credit facility may not allow us to make such a repurchase upon a change of control. If we could not refinance the revolving credit facility or otherwise obtain a waiver from the holders of such debt, we would be prohibited from repurchasing the notes, which would constitute an event of default under the indenture. In addition, certain important corporate events, such as leveraged recapitalizations that would increase the level of our indebtedness, would not constitute a "Change of Control" under the indenture. Because the definition of change of control under our revolving credit facility will differ from that under the indenture, there may be a change of control and resulting default under our revolving credit facility at a time when no change of control has occurred under the indenture. Please read "Description of New Notes—Repurchase at the Option of Holders—Change of Control."

Your ability to transfer the notes may be limited by the absence of a trading market.

There is no organized trading market for the notes. We do not currently intend to apply for listing of the notes on any securities exchange or stock market. Although the initial purchasers informed us, when the old notes were issued, that they intended to make a market in the notes, they are not obligated to do so. In addition, they may discontinue any such market making at any time without notice. The liquidity of any market for the notes will depend on the number of holders of those notes, the interest of securities dealers in making a market in those notes and other factors. Accordingly, we cannot assure you as to the development or liquidity of any market for the notes. Historically, the market for noninvestment grade debt has been subject to disruptions that have caused substantial volatility in the prices of securities similar to the notes. We cannot assure you that the market, if any, for the notes will be free from similar disruptions. Any such disruption may adversely affect the holders of the notes.

Table of Contents

Future trading prices of the notes will depend on many factors, including:

•: our subsidiaries' operating performance and financial condition;
•: our ability to complete the offer to exchange the new notes for the old notes;
•: the interest of the securities dealers in making a market in the notes; and
•: the market for similar securities.

USE OF PROCEEDS

The exchange offer is intended to satisfy our obligations under the registration rights agreement. We will not receive any cash proceeds from the issuance of the new notes in the exchange offer. In consideration for issuing the new notes as contemplated by this prospectus, we will receive old notes in a like principal amount. The terms of the new notes are substantially identical to the terms of the old notes, except that the transfer restrictions, registration rights and provisions for additional interest relating to the old notes do not apply to the new notes. Old notes surrendered in exchange for the new notes will be retired and cancelled and will not be reissued. Accordingly, the issuance of the new notes will not result in any change in our outstanding indebtedness.

RATIO OF EARNINGS TO FIXED CHARGES

The following table sets forth our ratio of earnings to fixed charges for the periods indicated on a consolidated historical basis. For purposes of computing the ratio of earnings to fixed charges, "earnings" are defined as income before taxes plus fixed charges less capitalized interest. "Fixed charges" consist of interest expensed and capitalized, amortization of deferred loan costs and an estimate of interest within rent expense.

EXCHANGE OFFER

We sold the old notes on June 17, 2013 pursuant to that certain purchase agreement, dated as of June 12, 2013, by and among Summit Holdings, Finance Corp., Summit Midstream GP, LLC, SMLP, the guarantors named therein and the initial purchasers named therein. The old notes were subsequently offered by the initial purchasers to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to non-U.S. persons pursuant to Regulation S under the Securities Act.

Purpose of the Exchange Offer

We sold the old notes in transactions that were exempt from or not subject to the registration requirements under the Securities Act. Accordingly, the old notes are subject to transfer restrictions. In general, you may not offer or sell the old notes unless either they are registered under the Securities Act or the offer or sale is exempt from, or not subject to, registration under the Securities Act and applicable state securities laws.

In connection with the sale of the old notes, we entered into a registration rights agreement with the initial purchasers of the old notes. In that agreement, we agreed to use our commercially reasonable efforts to file an exchange offer registration statement after the closing date following the offering of the old notes. Now, to satisfy our obligations under the registration rights agreement, we are offering holders of the old notes, who are able to make certain representations described below, the opportunity to exchange their old notes for the new notes in the exchange offer. The exchange offer will be open for a period of at least 20 full business days. During the exchange offer period, we will exchange the new notes for all old notes properly surrendered and not withdrawn before the expiration date. The new notes will be registered under the Securities Act, and the transfer restrictions, registration rights and provisions for additional interest relating to the old notes will not apply to the new notes.

Resale of New Notes

Based on no-action letters of the staff of the SEC issued to third parties, we believe that new notes may be offered for resale, resold and otherwise transferred by you without further compliance with the registration and prospectus delivery provisions of the Securities Act if:

•: you are not an "affiliate" of ours within the meaning of Rule 405 under the Securities Act;
•: such new notes are acquired in the ordinary course of your business; and
•: you do not intend to participate in a distribution of the new notes.

The staff of the SEC, however, has not considered the exchange offer for the new notes in the context of a no-action letter, and the staff of the SEC may not make a similar determination as in the no-action letters issued to these third parties.

If you tender in the exchange offer with the intention of participating in any manner in a distribution of the new notes, you:

•: cannot rely on such interpretations by the staff of the SEC; and
•: must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction.

Unless an exemption from registration is otherwise available, any securityholder intending to distribute new notes should be covered by an effective registration statement under the Securities Act. The registration statement should contain the selling securityholder's information required by Item 507 or 508, as applicable, of Regulation S-K under the Securities Act.

Table of Contents

This prospectus may be used for an offer to resell, resale or other transfer of new notes only as specifically described in this prospectus. If you are a broker-dealer, you may participate in the exchange offer only if you acquired the old notes as a result of market-making activities or other trading activities. Each broker-dealer that receives new notes for its own account in exchange for old notes, where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge by way of the letter of transmittal that it will deliver this prospectus in connection with any resale of the new notes. Please read the section captioned "Plan of Distribution" for more details regarding the transfer of new notes.

Terms of the Exchange Offer

Subject to the terms and conditions described in this prospectus and in the letter of transmittal, we will accept for exchange any old notes properly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the expiration date of the exchange offer. We will issue new notes in principal amount equal to the principal amount of old notes surrendered in the exchange offer. Old notes may be tendered only for new notes and only in denominations of $2,000 and integral multiples of $1,000 in excess thereof. We will deliver the new notes promptly after the expiration date of the exchange offer.

The exchange offer is not conditioned upon any minimum aggregate principal amount of old notes being tendered in the exchange offer.

As of the date of this prospectus, $300,000,000 in aggregate principal amount of 7¹/2% Senior Notes due 2021 representing old notes are outstanding. This prospectus is being sent to DTC, the sole registered holder of the old notes, and to all persons that we can identify as beneficial owners of the old notes. There will be no fixed record date for determining registered holders of old notes entitled to participate in the exchange offer.

We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act and the Securities Exchange Act of 1934, as amended, or the "Exchange Act," and the rules and regulations of the SEC. Old notes whose holders do not tender for exchange in the exchange offer will remain outstanding and continue to accrue interest. These old notes will be entitled to the rights and benefits such holders have under the indenture relating to the notes and the registration rights agreement.

We will be deemed to have accepted for exchange properly tendered old notes when we have given oral or written notice of the acceptance to the exchange agent and complied with the applicable provisions of the registration rights agreement. The exchange agent will act as agent for the tendering holders for the purposes of receiving the new notes from us.

If you tender old notes in the exchange offer, you will not be required to pay brokerage commissions or fees or, subject to the letter of transmittal, transfer taxes with respect to the exchange of old notes. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the exchange offer. Please read "—Fees and Expenses" for more details regarding fees and expenses incurred in connection with the exchange offer.

We will return any old notes that we do not accept for exchange for any reason without expense to their tendering holders promptly after the expiration or termination of the exchange offer.

Expiration Date

The exchange offer will expire at 5:00 p.m., New York City time, on April 7, 2014, unless, in our sole discretion, we extend it.

Table of Contents

Extensions, Delays in Acceptance, Termination or Amendment

We expressly reserve the right, at any time or various times, to extend the period of time during which the exchange offer is open. We may delay acceptance of any old notes by giving oral or written notice of such extension to their holders at any time until the exchange offer expires or terminates. During any such extensions, all old notes previously tendered will remain subject to the exchange offer, and we may accept them for exchange.

To extend the exchange offer, we will notify the exchange agent orally or in writing of any extension. We will notify the holders of old notes of the extension via a press release issued no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date.

If any of the conditions described below under "—Conditions to the Exchange Offer" have not been satisfied, we reserve the right, in our sole discretion

•: to extend the exchange offer,
•: to delay accepting for exchange any old notes, or
•: to terminate the exchange offer,

by giving oral or written notice of such delay, extension or termination to the exchange agent. Subject to the terms of the registration rights agreement, we also reserve the right to amend the terms of the exchange offer in any manner.

Any such delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice thereof to holders of the old notes. Any notice relating to the extension of the exchange offer will disclose the number of securities tendered as of the date of the notice, as required by Rule 14e-1(d) under the Exchange Act. If we amend the exchange offer in a manner that we determine to constitute a material change, we will promptly disclose such amendment by means of a prospectus supplement. The prospectus supplement will be distributed to holders of the old notes. Depending upon the significance of the amendment and the manner of disclosure to holders, we will extend the exchange offer if it would otherwise expire during such period. If an amendment constitutes a material change to the exchange offer, including the waiver of a material condition, we will extend the exchange offer, if necessary, to remain open for at least five business days after the date of the amendment. In the event of any increase or decrease in the consideration we are offering for the old notes or in the percentage of old notes being sought by us, we will extend the exchange offer to remain open for at least 10 business days after the date we provide notice of such increase or decrease to the registered holders of old notes.

If we delay accepting any old notes or terminate the exchange offer, we will promptly pay the consideration offered, or return any old notes deposited, pursuant to the exchange offer as required by Rule 14e-1(c).

Conditions to the Exchange Offer

We will not be required to accept for exchange, or exchange any new notes for, any old notes if the exchange offer, or the making of any exchange by a holder of old notes, would violate applicable law or policy of the staff of the SEC. Similarly, we may terminate the exchange offer as provided in this prospectus before expiration of the offer in the event of such a potential violation.

We will not be obligated to accept for exchange the old notes of any holder that has not made to us the representations described under "—Procedures for Tendering" and "Plan of Distribution" and such other representations as may be reasonably necessary under applicable SEC rules, regulations or interpretations to allow us to use an appropriate form to register the new notes under the Securities Act.

Table of Contents

Additionally, we will not accept for exchange any old notes tendered, and will not issue new notes in exchange for any such old notes, if at such time any stop order has been threatened or is in effect with respect to the exchange offer registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939, as amended.

We expressly reserve the right to amend or terminate the exchange offer, and to reject for exchange any old notes not previously accepted for exchange, upon the occurrence of any of the conditions to the exchange offer specified above. We will give oral or written notice of any extension, amendment, non-acceptance or termination to the holders of the old notes as promptly as practicable.

These conditions are for our sole benefit, and we may assert them or waive them in whole or in part at any time or at various times prior to the expiration of the exchange offer in our sole discretion. If we fail at any time to exercise any of these rights, this failure will not mean that we have waived our rights. Each such right will be deemed an ongoing right that we may assert at any time or at various times prior to the expiration of the exchange offer.

Procedures for Tendering

To participate in the exchange offer, you must properly tender your old notes to the exchange agent as described below. We will only issue new notes in exchange for old notes that you timely and properly tender. Therefore, you should allow sufficient time to ensure timely delivery of the old notes, and you should follow carefully the instructions on how to tender your old notes. It is your responsibility to properly tender your old notes. We have the right to waive any defects. However, we are not required to waive defects, and neither we nor the exchange agent is required to notify you of any defects in your tender.

If you have any questions or need help in exchanging your old notes, please call the exchange agent whose address and phone number are described in the letter of transmittal included as Annex A to this prospectus.

All of the old notes were issued in book-entry form, and all of the old notes are currently represented by global certificates registered in the name of Cede & Co., the nominee of DTC. We have confirmed with DTC that the old notes may be tendered using ATOP. The exchange agent will establish an account with DTC for purposes of the exchange offer promptly after the commencement of the exchange offer, and DTC participants may electronically transmit their acceptance of the exchange offer by causing DTC to transfer their old notes to the exchange agent using the ATOP procedures. In connection with the transfer, DTC will send an "agent's message" to the exchange agent. The agent's message will state that DTC has received instructions from the participant to tender old notes and that the participant agrees to be bound by the terms of the letter of transmittal.

By using the ATOP procedures to exchange old notes, you will not be required to deliver a letter of transmittal to the exchange agent. However, you will be bound by its terms just as if you had signed it.

There is no procedure for guaranteed late delivery of the old notes.

Each broker-dealer that receives new notes for its own account in exchange for old notes, where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. Please read "Plan of Distribution."

Determinations in the Exchange Offer. We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered old notes and withdrawal of tendered old notes. Our determination will be final and binding on all parties. We reserve the absolute right to reject any old notes not properly tendered or any old notes our acceptance of which would, in

Table of Contents

the opinion of our counsel, be unlawful. We also reserve the right to waive any defect, irregularities or conditions of tender as to particular old notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, all defects or irregularities in connection with tenders of old notes must be cured within such time as we shall determine. Although we intend to notify holders of defects or irregularities with respect to tenders of old notes, neither we, the exchange agent nor any other person will incur any liability for failure to give such notification. Tenders of old notes will not be deemed made until such defects or irregularities have been cured or waived. Any old notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the tendering holder promptly upon expiration or termination of the exchange offer.

When We Will Issue New Notes. In all cases, we will issue new notes for old notes that we have accepted for exchange in the exchange offer only after the exchange agent receives, prior to 5:00 p.m., New York City time, on the expiration date:

•: a book-entry confirmation of such old notes into the exchange agent's account at DTC; and
•: a properly transmitted agent's message.

Return of Old Notes Not Accepted or Exchanged. If we do not accept any tendered old notes for exchange or if old notes are submitted for a greater principal amount than the holder desires to exchange, the unaccepted or non-exchanged old notes will be returned without expense to their tendering holder. Such non-exchanged old notes will be credited to an account maintained with DTC. These actions will occur promptly upon the expiration or termination of the exchange offer.

Your Representations to Us. By agreeing to be bound by the letter of transmittal, you will represent to us that, among other things:

•: any new notes that you receive will be acquired in the ordinary course of your business;
•: you have not engaged in and have no intent to engage in (nor have you entered into any arrangement or understanding with any person or entity to participate in) a distribution of the new notes in violation of the provisions of the Securities Act;
•: you are not an "affiliate" (within the meaning of Rule 405 under the Securities Act) of Summit Holdings, Finance Corp. or the guarantors; and
•: if you are a broker-dealer that will receive new notes for your own account in exchange for old notes that were acquired as a result of market-making activities or other trading activities, then you will deliver a prospectus (or to the extent permitted by law, make available a prospectus to purchasers) in connection with any resale of the new notes.

Withdrawal of Tenders

Except as otherwise provided in this prospectus, you may withdraw your tender at any time prior to 5:00 p.m., New York City time, on the expiration date of the exchange offer. For a withdrawal to be effective you must comply with the appropriate ATOP procedures. Any notice of withdrawal must specify the name and number of the account at DTC to be credited with withdrawn old notes and otherwise comply with the ATOP procedures.

We will determine all questions as to the validity, form, eligibility and time of receipt of a notice of withdrawal. Our determination shall be final and binding on all parties. We will deem any old notes so withdrawn not to have been validly tendered for exchange for purposes of the exchange offer.

Table of Contents

Any old notes that have been tendered for exchange but that are not exchanged for any reason will be credited to an account maintained with DTC for the old notes. This return or crediting will take place promptly upon withdrawal, rejection of tender, expiration or termination of the exchange offer. You may retender properly withdrawn old notes by following the procedures described under "—Procedures for Tendering" above at any time on or prior to the expiration date of the exchange offer.

Fees and Expenses

We will bear the expenses of soliciting tenders. The principal solicitation is being made by mail; however, we may make additional solicitation by e-mail, telephone or in person by our officers and regular employees and those of our affiliates.

We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and reimburse it for its related reasonable out-of-pocket expenses.

We will pay the cash expenses to be incurred in connection with the exchange offer. They include:

•: SEC registration fees;
•: fees and expenses of the exchange agent and trustee;
•: accounting and legal fees and printing costs; and
•: related fees and expenses.

Transfer Taxes

We will pay all transfer taxes, if any, applicable to the exchange of old notes in the exchange offer. Each tendering holder, however, will be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if a transfer tax is imposed for any reason other than the exchange of old notes in the exchange offer.

Consequences of Failure to Exchange

If you do not exchange your old notes for new notes in the exchange offer, the old notes you hold will remain outstanding and continue to accrue interest, but will continue to be subject to the existing restrictions on transfer. In general, you may not offer or sell the old notes except under an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. After the expiration of this exchange offer, we do not intend to register old notes under the Securities Act unless the registration rights agreement requires us to do so.

Accounting Treatment

We will record the new notes in our accounting records at the same carrying value as the old notes. This carrying value is the aggregate principal amount of the old notes, as reflected in our accounting records on the date of exchange. Accordingly, we will not recognize any gain or loss for accounting purposes in connection with the exchange offer, other than the recognition of the fees and expenses of the offering as stated under "—Fees and Expenses."

Table of Contents

Other

Participation in the exchange offer is voluntary, and you should consider carefully whether to accept. You are urged to consult your financial and tax advisors in making your own decision on what action to take.

We may in the future seek to acquire untendered old notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plans to acquire any old notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered old notes.

DESCRIPTION OF OTHER INDEBTEDNESS

Revolving Credit Facility

Summit Holdings' revolving credit facility (i) has a borrowing capacity of $700 million, (ii) matures in November 2018 and (iii) has an accordion feature to increase borrowing capacity up to $200 million. As of February 15, 2014, we had total debt of approximately $611.0 million, and we had $389.0 million of remaining borrowing capacity under the revolving credit facility. The revolving credit facility is secured by the membership interests of Summit Holdings and those of its subsidiaries. Substantially all of Summit Holdings' and its subsidiaries' assets are pledged as collateral under the revolving credit facility. The facility, and Summit Holdings' obligations, are guaranteed by SMLP and each of its subsidiaries. At our option, borrowings under the revolving credit facility bear interest at a variable rate per annum equal to either (i) the London InterBank Offered Rate plus the applicable margins ranging from 1.75% to 2.75% or (ii) a base rate plus the applicable margins ranging from 0.75% to 1.75%.

The revolving credit facility contains affirmative and negative covenants customary for credit facilities of its size and nature, that, among other things, limit or restrict Summit Holdings' ability (as well as the ability of its subsidiaries) to:

•: permit the ratio of our trailing 12-month EBITDA to our consolidated cash interest charges as of the end of any fiscal quarter to be less than 2.50 to 1.00;
•: permit the ratio of our consolidated net debt to trailing 12-month EBITDA on the last day of any quarter to be above 5.00 to 1.00 (or 5.50 to 1.00 if we have made certain business acquisitions);
•: incur any additional debt, subject to customary exceptions for certain permitted additional debt, or incur liens on assets, subject to customary exceptions for permitted liens;
•: make any investments, subject to customary exceptions for certain permitted investments;
•: engage in certain mergers, consolidations, sales of assets or acquisitions, subject to customary exceptions for permitted transactions of such types;
•: pay dividends or make cash distributions, provided that it may make quarterly distributions to SMLP, so long as no default or event of default under the amended and restated credit agreement then exists or would result therefrom, and subject to compliance (on both a pro forma basis and after giving effect to the making of such distribution) with our financial performance covenants under the amended and restated credit agreement;
•: enter into any swap agreements or power purchase agreements, subject to customary exceptions, such as the entry into swap agreements and power purchase agreements in the ordinary course of business; and
•: enter into leases that would cumulatively obligate payments in excess of $30.0 million over any 12-month period.

As of September 30, 2013, we were in compliance with the financial and other covenants in our revolving credit facility.

The revolving credit facility also contains events of default customary for credit facilities of its size and nature, including, but not limited to:

•: events of default resulting from our failure to comply with covenants;
•: the occurrence of a change of control of SMLP's general partner;
•: the institution of insolvency or similar proceedings against us;

Table of Contents

•: the occurrence of a default under any other material indebtedness we may have; and
•: the termination of any one or more or our gas gathering agreements accounting for 25% or more of our revenue that results in a material adverse effect (as defined in the amended and restated credit agreement) and for which a replacement gas gathering agreement with substantially similar terms is not entered into within 30 days after such termination.

Upon the occurrence of an event of default, subject to the terms and conditions of the revolving credit facility, the lenders may, in addition to exercising other remedies, declare any outstanding principal and any accrued and unpaid interest to be immediately due and payable. There have been no defaults on the revolving credit facility.

DESCRIPTION OF NEW NOTES

We are offering to exchange up to $300,000,000 aggregate principal amount of our new 7¹/2% Senior Notes due 2021, which have been registered under the Securities Act, referred to in this prospectus as the "new notes," for any and all of our outstanding unregistered 7¹/2% Senior Notes due 2021, referred to in this prospectus as the "old notes." We issued the old notes on June 17, 2013 in a transaction exempt from registration under the Securities Act. We are offering you new notes in exchange for old notes in order to satisfy our registration obligations from that previous transaction. The new notes will be treated as a single class with any old notes that remain outstanding after the completion of the exchange offer. The new notes will be issued, and the old notes are outstanding, under an indenture dated as of June 17, 2013, among Summit Midstream Holdings, LLC and Summit Midstream Finance Corp., as issuers, the Guarantors (as defined below) party thereto and U.S. Bank National Association, as trustee, as supplemented and amended. You can find the definition of various terms used in this Description of New Notes under "—Certain Definitions" below.

This Description of New Notes is intended to be a useful overview of the material provisions of the notes, the guarantees and the indenture. Since this Description of New Notes is only a summary, you should refer to the indenture which is filed as an exhibit to the registration statement of which this prospectus is a part, for a complete description of our obligations and your rights.

In this description, the term "Company" refers only to Summit Midstream Holdings, LLC and not to any of its subsidiaries, the term "Finance Corp." refers to Summit Midstream Finance Corp., the term "Parent" refers only to Summit Midstream Partners, LP and not to any of its subsidiaries and the term "Issuers" refers to the Company and Finance Corp. The term "notes" in this section of the prospectus includes both the old notes issued on June 17, 2013 and the new notes, unless the context otherwise requires.

If the exchange offer is consummated, Holders of old notes who do not exchange their old notes for new notes will vote together with the Holders of the new notes for all relevant purposes under the indenture. In that regard, the indenture requires that certain actions by the Holders under the indenture (including acceleration after an Event of Default) must be taken, and certain rights must be exercised, by Holders of specified minimum percentages of the aggregate principal amount of all outstanding notes issued under the indenture. In determining whether Holders of the requisite percentage in aggregate principal amount of notes have given any notice, consent or waiver or taken any other action permitted under the indenture, any old notes that remain outstanding after the exchange offer will be aggregated with the new notes, and the Holders of these old notes and new notes will vote together as a single class for all such purposes. Accordingly, all references in this Description of New Notes to specified percentages in aggregate principal amount of the outstanding notes mean, at any time after the exchange offer for the old notes is consummated, such percentage in aggregate principal amount of such old notes and the new notes then outstanding.

The registered Holder of a note will be treated as the owner of it for all purposes. Only registered Holders will have rights under the indenture.

Brief Description of the Notes and the Guarantees

The Notes. The notes are:

•: general unsecured obligations of the Issuers;
•: equal in right of payment with all existing and future Senior Debt (as defined below) of either of the Issuers; and
•: fully and unconditionally and jointly and severally guaranteed by the Guarantors on a senior unsecured basis.

Table of Contents

The Guarantees. Currently, the notes are fully and unconditionally and jointly and severally guaranteed by the Parent and all of the Parent's existing Subsidiaries (other than the Company and Finance Corp.) (the "Subsidiary Guarantors" and, together with the Parent, the "Guarantors").

Each guarantee of the notes is:

•: a general unsecured obligation of the Guarantor; and
•: equal in right of payment with all existing and future Senior Debt of that Guarantor.

As of February 15, 2014, the Company and the Guarantors had:

•: total Senior Debt of approximately $611.0 million, consisting of the notes and approximately $311.0 million of secured Senior Debt outstanding under the Credit Agreement; and
•: no Indebtedness contractually subordinated to the notes or the guarantees, as applicable.

�� The indenture permits the Parent and its Restricted Subsidiaries to incur additional Indebtedness, including additional secured Indebtedness.

Currently, all of the Parent's existing subsidiaries (other than the Company and Finance Corp.) have fully and unconditionally and jointly and severally guaranteed the notes. However, in the future, certain of the Parent's newly created or acquired Subsidiaries may not guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of these non-guarantor Subsidiaries, the non-guarantor Subsidiaries will pay current outstanding obligations to the holders of their debt and their trade creditors before they will be able to distribute any of their assets to the Issuers.

Currently, all of the Parent's Subsidiaries are "Restricted Subsidiaries." However, under the circumstances described below under the subheading "—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries," the Parent will be permitted to designate certain of its Subsidiaries as "Unrestricted Subsidiaries." Our Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indenture. Our Unrestricted Subsidiaries will not guarantee the notes.

Principal, Maturity and Interest

The Issuers issued the old notes with an initial maximum aggregate principal amount of $300.0 million. In addition to the new notes offered hereby and the old notes, the Issuers may issue additional notes from time to time, provided that the additional notes are fungible with the notes for U.S. federal income tax purposes so that such additional notes will trade as part of a single class with the initial notes. Any offering of additional notes is subject to the covenant described below under the caption "—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Securities." Any old notes remaining outstanding after the completion of the exchange offer and any additional notes subsequently issued under the indenture, together with all new notes, will be treated as a single class for all purposes under the indenture, including, without limitation, for waivers, amendments and offers to purchase. The Issuers will issue notes in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The notes will mature on July 1, 2021.

Interest on the notes accrues at the rate of 7.500% per annum, and is payable semi-annually in arrears on January 1 and July 1, commencing on January 1, 2014. The Issuers will make each interest payment to the Holders of record on the December 15 and June 15 immediately preceding each interest payment date.

In the case of the new notes, all interest accrued on the old notes from the original issue date, June 17, 2013, will be treated as having accrued on the new notes that are issued in exchange for the old notes. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

Table of Contents

Methods of Receiving Payments on the Notes

If a Holder has given wire transfer instructions to the Issuers, the Issuers will pay all principal, interest and premium, if any, on that Holder's notes in accordance with those instructions. All other payments on the notes will be made at the office or agency of the paying agent and registrar within the City and State of New York unless the Issuers elect to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders.

Paying Agent and Registrar for the Notes

The trustee is currently acting as paying agent and registrar. The Issuers may change the paying agent or registrar without prior notice to the Holders of the notes, and the Parent or any of its Restricted Subsidiaries may act as paying agent or registrar.

Transfer and Exchange

A Holder may transfer or exchange notes in accordance with the indenture. The registrar and the trustee may require a Holder to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. No service charge will be imposed by the Issuers, the trustee or the registrar for any registration of transfer or exchange of notes, but Holders will be required to pay all taxes due on transfer. The Issuers are not required to transfer or exchange any note selected for redemption. Also, the Issuers are not required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed.

Guarantees

The Parent and all of the Parent's existing Subsidiaries (excluding the Company and Finance Corp.) have fully and unconditionally and jointly and severally guaranteed the old notes on a senior unsecured basis, and they will guarantee the new notes on the same basis. In the future, the Restricted Subsidiaries of the Parent will be required to guarantee the notes under the circumstances described under "—Certain Covenants—Additional Subsidiary Guarantees." The obligations of each Subsidiary Guarantor under its Subsidiary Guarantee will be limited as necessary to prevent that Subsidiary Guarantee from constituting a fraudulent conveyance under applicable law. See "Risk Factors—Risks Related to Our Indebtedness and the Notes—Federal and state statutes allow courts, under specific circumstances, to void subsidiary guarantees and require noteholders to return payments received from subsidiary guarantors."

A Subsidiary Guarantor may not sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person), another Person, other than the Parent, the Company or another Subsidiary Guarantor, unless:

(1)

immediately after giving effect to such transaction, no Default or Event of Default exists; and

(2)

either:

(a): the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving any such consolidation or merger (if other than the Subsidiary Guarantor) unconditionally assumes, pursuant to a supplemental indenture substantially in the form specified in the indenture, all the obligations of that Subsidiary Guarantor under the notes, the indenture and its Guarantee on terms set forth therein; or
(b): such sale or other disposition does not violate the "Asset Sales" provisions of the indenture.

Table of Contents

The Guarantee of a Subsidiary Guarantor will be automatically released:

(1): in connection with any sale or other disposition of all or substantially all of the properties or assets of that Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Parent, if the sale or other disposition does not violate the "Asset Sales" provisions of the indenture;
(2): in connection with any sale or other disposition of the Capital Stock of that Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Parent, if the sale or other disposition does not violate the "Asset Sales" provisions of the indenture and the Subsidiary Guarantor ceases to be a Restricted Subsidiary of the Parent as a result of such sale or other disposition;
(3): if the Parent designates any Restricted Subsidiary that is a Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of the indenture;
(4): upon Legal Defeasance or Covenant Defeasance as described below under the caption "—Legal Defeasance and Covenant Defeasance" or upon satisfaction and discharge of the indenture as described below under the caption "—Satisfaction and Discharge"; or
(5): at such time as such Subsidiary Guarantor ceases to guarantee any Indebtedness the Parent, either Issuer or any other Subsidiary Guarantor under any Credit Facility.

Optional Redemption

At any time prior to July 1, 2016, the Issuers may on any one or more occasions redeem up to 35% of the aggregate principal amount of the notes issued under the indenture at a redemption price of 107.500% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), in an amount not greater than the net cash proceeds of one or more Equity Offerings by the Parent, provided that:

(1): at least 65% of the aggregate principal amount of the notes issued under the indenture remains outstanding immediately after the occurrence of such redemption (excluding notes held by the Parent and its Subsidiaries); and
(2): the redemption occurs within 120 days of the date of the closing of each such Equity Offering.

On and after July 1, 2016, the Issuers may redeem all or a part of the notes at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the notes redeemed to the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), if redeemed during the twelve-month period beginning on July 1 of the years indicated below:

Year

2016	105.625	%
2017	103.750	%
2018	101.875	%
2019 and thereafter	100.000	%

Prior to July 1, 2016, the Issuers may redeem all or part of the notes at a redemption price equal to the sum of:

(1): the principal amount thereof, plus

Table of Contents

(2): the Make Whole Premium at the redemption date,

plus accrued and unpaid interest, if any, to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

Selection and Notice

If less than all of the notes are to be redeemed at any time, the trustee will select notes for redemption on a pro rata basis (or, in the case of notes issued in global form as discussed under "—Book-Entry, Delivery and Form," based on a method as DTC, in New York, New York, or its nominee or successor may require or, where such nominee or successor is the trustee, a method that most nearly approximates pro rata selection as the trustee deems fair and appropriate unless otherwise required by law) unless otherwise required by law or applicable stock exchange or depositary requirements.

No notes of $2,000 or less can be redeemed in part. Notices of optional redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of notes to be redeemed at its registered address, except that optional redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the indenture. Notices of redemption may not be conditional, except that any redemption pursuant to the first paragraph under "—Optional Redemption," may, at the Company's discretion, be subject to completion of the related Equity Offering.

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the Holder of notes upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest ceases to accrue on notes or portions of them called for redemption.

Mandatory Redemption

Except as set forth below under "—Repurchase at the Option of Holders," neither of the Issuers is required to make mandatory redemption or sinking fund payments with respect to the notes or to repurchase the notes at the option of the Holders.

Repurchase at the Option of Holders

Change of Control

If a Change of Control occurs, unless the Issuers have previously or concurrently exercised their right to redeem all of the notes as described under "—Optional Redemption," each Holder of notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that Holder's notes pursuant to a Change of Control Offer on the terms set forth in the indenture. In the Change of Control Offer, the Company will offer a cash payment (a "Change of Control Payment") equal to 101% (or, at the Company's election, a higher percentage) of the aggregate principal amount of notes repurchased plus accrued and unpaid interest, if any, on the notes repurchased, to the date of settlement (the "Change of Control Settlement Date"), subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the Change of Control Settlement Date. Within 30 days following any Change of Control, unless the Issuers have previously or concurrently exercised their right to redeem all of the notes as described under "—Optional Redemption," the Company will mail a

Table of Contents

notice to each Holder and the trustee describing the transaction or transactions that constitute the Change of Control and offering to repurchase notes as of the Change of Control Settlement Date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the indenture and described in such notice.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the indenture by virtue of such conflict.

Promptly following the expiration of the Change of Control Offer, the Company will, to the extent lawful, accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer. Promptly thereafter on the Change of Control Settlement Date, the Company will:

(1): deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and
(2): deliver or cause to be delivered to the trustee the notes properly accepted together with an officers' certificate stating the aggregate principal amount of notes or portions of notes being purchased by the Company.

On the Change of Control Settlement Date, the paying agent will mail to each Holder of notes properly tendered the Change of Control Payment for such notes (or, if all the notes are then in global form, make such payment through the facilities of DTC), and the trustee will authenticate and mail (or cause to be transferred by book entry) to each Holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided, however, that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Settlement Date.

The Credit Agreement provides that certain change of control events with respect to the Company would constitute an event of default thereunder, entitling the lenders, among other things, to accelerate the maturity of all indebtedness outstanding thereunder. Any future credit agreements or other agreements relating to indebtedness to which the Company or any Guarantor becomes a party may contain similar restrictions and provisions. The indenture provides that, prior to complying with any of the provisions of this "Change of Control" covenant, but in any event no later than the Change of Control Settlement Date, the Company or any Guarantor must either repay all of its other outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing such Senior Debt to permit the repurchase of notes required by this covenant.

The provisions described above that require the Company to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control, the indenture does not contain provisions that permit the Holders of the notes to require that the Company repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by the Company and purchases all notes properly tendered and not withdrawn under the Change of Control Offer. Notwithstanding anything to the contrary contained in the indenture, a Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the consummation of such Change of Control if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made.

Table of Contents

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of "all or substantially all" of the properties or assets of the Parent and its Restricted Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of notes to require the Company to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the properties or assets of the Parent and its Subsidiaries taken as a whole to another Person or group may be uncertain.

In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding notes accept a Change of Control Offer and the Company purchases all of the notes held by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days' prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described above, to redeem all of the notes that remain outstanding following such purchase at a redemption price equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest on the notes that remain outstanding, to the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date).

Asset Sales

The Parent will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1)

the Parent (or a Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of;

(2)

the fair market value is determined by (a) an executive officer of the General Partner if the value is less than $20.0 million and evidenced by an officers' certificate delivered to the trustee, or (b) the Parent's Board of Directors if the value is $20.0 million or more and evidenced by a resolution of the Board of Directors set forth in an officers' certificate delivered to the trustee; and

(3)

at least 75% of the aggregate consideration received by the Parent and its Restricted Subsidiaries in the Asset Sale is in the form of cash. For purposes of this provision, each of the following will be deemed to be cash:

(a): any liabilities, as shown on the Parent's or any of its Restricted Subsidiary's most recent balance sheet, of the Parent or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the notes or any Guarantee) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Parent or such Restricted Subsidiary from further liability;
(b): any securities, notes or other obligations received by the Parent or any of its Restricted Subsidiaries from such transferee that are, within 90 days after the Asset Sale, converted by the Parent or such Subsidiary into cash, to the extent of the cash received in that conversion;
(c): any Capital Stock or assets of the kind referred to in clause (2) or (4) of the next paragraph; and
(d): any Designated Non-cash Consideration received by the Parent or any of its Restricted Subsidiaries in such Asset Sale having an aggregate fair market value (as determined in

Table of Contents

good faith by the Parent), taken together with all other Designated Non-cash Consideration received pursuant to this clause (d), not to exceed the greater of (i) $15.0 million and (ii) 2% of the Parent's Consolidated Net Tangible Assets (with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value).

Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Parent or any of its Restricted Subsidiaries may apply those Net Proceeds at its option to any combination of the following:

(1): to repay Senior Debt;
(2): to acquire all or substantially all of the properties or assets, or any of the Voting Stock, of a Person primarily engaged in a Permitted Business, if, after giving effect to any such acquisition of Voting Stock, such Person becomes a Restricted Subsidiary;
(3): to make capital expenditures in respect of a Permitted Business; or
(4): to acquire other long-term assets that are used or useful in a Permitted Business.

The requirement of clause (2) or (4) of the immediately preceding paragraph shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred to therein is entered into by the Parent or any of its Restricted Subsidiaries with a Person other than an Affiliate of the Parent within the time period specified in the preceding paragraph and such Net Proceeds are subsequently applied in accordance with such contract within 180 days following the date such agreement is entered into.

Pending the final application of any Net Proceeds, the Parent or any of its Restricted Subsidiaries may invest the Net Proceeds in any manner that is not prohibited by the indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph will constitute "Excess Proceeds."

On the 361st day after the Asset Sale (or, at the Company's option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $25.0 million, the Company will make an Asset Sale Offer to all Holders of notes, and all holders of other Indebtedness that is pari passu with the notes containing provisions similar to those set forth in the indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of settlement, subject to the right of Holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the date of settlement, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Parent or any of its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by the indenture. If the aggregate principal amount of notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the trustee will select the notes and such other pari passu Indebtedness to be purchased on a pro rata basis (except that any notes represented by a note in global form will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the trustee, a method that most nearly approximates pro rata selection as the trustee deems fair and appropriate unless otherwise required by law). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the "Asset Sales" provisions of the indenture by virtue of such compliance.

Certain Covenants

Restricted Payments

The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(1): declare or pay any dividend or make any other payment or distribution on account of the Parent's or any of its Restricted Subsidiaries' Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Parent or any of its Restricted Subsidiaries) or to the direct or indirect holders of the Parent's or any of its Restricted Subsidiaries' Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Parent or payable to the Parent or a Restricted Subsidiary of the Parent);
(2): purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Parent) any Equity Interests of the Parent or any direct or indirect parent of the Parent;
(3): make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the notes or the Guarantees (excluding any intercompany Indebtedness between or among the Parent and any of its Restricted Subsidiaries), except a payment of interest or principal at the Stated Maturity thereof; or
(4): make any Restricted Investment (all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as "Restricted Payments"),

unless, at the time of and after giving effect to such Restricted Payment, no Default (except a Reporting Default) or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment and either:

(1)

if the Fixed Charge Coverage Ratio for the Parent's most recently ended four full fiscal quarters for which internal financial statements are available at the time of such Restricted Payment (the "Trailing Four Quarters") is not less than 1.75 to 1.0, such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Parent and its Restricted Subsidiaries (excluding Restricted Payments permitted by clauses (2), (3), (4), (5) and (6) of the next succeeding paragraph) with respect to the quarter for which such Restricted Payment is made, is less than the sum, without duplication, of:

(a): Available Cash from Operating Surplus with respect to the Parent's preceding fiscal quarter, plus
(b): 100% of the aggregate net proceeds received by the Parent (including the fair market value of property or securities other than cash (including Capital Stock of Persons, other than the Parent or a Subsidiary of the Parent, engaged primarily in a Permitted Business) or long-term assets that are used or useful in a Permitted Business to the extent acquired in consideration of Equity Interests of the Parent (other than Disqualified Stock)) after the date of the indenture as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Parent (other than Disqualified Stock) or from the issue or sale of convertible or exchangeable Disqualified Stock or convertible or exchangeable debt securities of the Parent that have been converted into or exchanged for such Equity

Table of Contents

Interests (other than Equity Interests (or Disqualified Stock or debt securities) sold to a Restricted Subsidiary of the Parent), plus

(c): to the extent that any Restricted Investment that was made after the date of the indenture is sold for cash or otherwise cancelled, liquidated or repaid for cash, the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any), plus
(d): the net reduction in Restricted Investments resulting from dividends, repayments of loans or advances, or other transfers of assets in each case to the Parent or any of its Restricted Subsidiaries from any Person (including, without limitation, Unrestricted Subsidiaries) or from redesignations of Unrestricted Subsidiaries as Restricted Subsidiaries, to the extent such amounts have not been included in Available Cash from Operating Surplus for any period commencing on or after the date of the indenture (items (b), (c) and (d) being referred to as "Incremental Funds"), minus
(e): the aggregate amount of Incremental Funds previously expended pursuant to this clause (1) and clause (2) below; or

(2)

if the Fixed Charge Coverage Ratio for the Trailing Four Quarters is less than 1.75 to 1.0, such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Parent and its Restricted Subsidiaries (excluding Restricted Payments permitted by clauses (2), (3), (4), (5) and (6) of the next succeeding paragraph) with respect to the quarter for which such Restricted Payment is made (such Restricted Payments for purposes of this clause (2) meaning only distributions on the Parent's common units, subordinated units, or incentive distribution rights, plus the related distribution to the General Partner), is less than the sum, without duplication, of:

(a): $90.0 million less the aggregate amount of all prior Restricted Payments made by the Parent and its Restricted Subsidiaries pursuant to this clause (2)(a) since the date of the indenture, plus
(b): Incremental Funds to the extent not previously expended pursuant to this clause (2) or clause (1) above.

So long as no Default (except a Reporting Default) or Event of Default has occurred and is continuing or would be caused thereby (except with respect to clause (1) below under which the payment of a distribution or dividend is permitted), the preceding provisions will not prohibit:

(1): the payment of any dividend or distribution within 60 days after the date of its declaration, if at the date of declaration the payment would have complied with the provisions of the indenture;
(2): the purchase, redemption, defeasance or other acquisition or retirement of any subordinated Indebtedness of the Company or any Guarantor or of any Equity Interests of the Parent in exchange for, or out of the net cash proceeds of the substantially concurrent (a) contribution (other than from a Restricted Subsidiary of the Parent) to the equity capital of the Parent or (b) sale (other than to a Restricted Subsidiary of the Parent) of Equity Interests of the Parent (other than Disqualified Stock), with a sale being deemed substantially concurrent if such purchase, redemption, defeasance or other acquisition or retirement occurs not more than 120 days after such sale; provided, however, that the amount of any such net cash proceeds that are utilized for any such purchase, redemption, defeasance or other acquisition or retirement will be excluded (or deducted, if included) from the calculation of Available Cash from Operating Surplus and Incremental Funds;

Table of Contents

(3): the purchase, redemption, defeasance or other acquisition or retirement of subordinated Indebtedness of the Company or any Guarantor with the net cash proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness;
(4): the payment of any dividend or distribution by a Restricted Subsidiary of the Parent to the holders of its Equity Interests on a pro rata basis;
(5): the purchase, redemption or other acquisition or retirement for value of any Equity Interests of the Parent or any Restricted Subsidiary of the Parent pursuant to any director or employee equity subscription agreement or equity option agreement or other employee benefit plan or to satisfy obligations under any Equity Interests appreciation rights or option plan or similar arrangement; provided, however, that the aggregate price paid for all such purchased, redeemed, acquired or retired Equity Interests may not exceed $5.0 million in any calendar year, with any portion of such $5.0 million amount that is unused in any calendar year to be carried forward to successive calendar years and added to such amount; or
(6): the purchase, repurchase, redemption or other acquisition or retirement for value of Equity Interests deemed to occur upon the exercise of unit options, warrants, incentives, rights to acquire Equity Interests or other convertible securities if such Equity Interests represent a portion of the exercise or exchange price thereof, and any purchase, repurchase, redemption or other acquisition or retirement for value of Equity Interests made in lieu of withholding taxes in connection with any exercise or exchange of unit options, warrants, incentives or rights to acquire Equity Interests.

The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the Restricted Investment proposed to be made or the asset(s) or securities proposed to be transferred or issued by the Parent or a Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any Restricted Investment, assets or securities that are required to be valued by this covenant will be determined, in the case of amounts under $20.0 million, by an officer of the General Partner and, in the case of amounts over $20.0 million, by the Board of Directors of the Parent, whose determination shall be evidenced by a Board Resolution. Not later than the date of making any Restricted Payment (excluding any Restricted Payment described in the preceding clause (2), (3), (4), (5) or (6)) the Parent will deliver to the trustee an officers' certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this "Restricted Payments" covenant were computed.

Incurrence of Indebtedness and Issuance of Preferred Securities

The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt), and the Parent will not, and will not permit any of its Restricted Subsidiaries to, issue any Disqualified Stock, and the Parent will not permit any of its Restricted Subsidiaries to issue any preferred securities; provided, however, that the Parent and any of its Restricted Subsidiaries may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or preferred securities, if, for the Parent's most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred securities are issued, the Fixed Charge Coverage Ratio would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Stock or preferred securities had been issued, as the case may be, at the beginning of such four-quarter period.

Table of Contents

The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness (collectively, "Permitted Debt") or the issuance of any preferred securities described in clause (11) below:

(1)

the incurrence by the Parent or any of its Restricted Subsidiaries of additional Indebtedness (including letters of credit) under one or more Credit Facilities, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Parent and its Subsidiaries thereunder) and then outstanding does not exceed the greater of (a) $600.0 million or (b) $400.0 million plus 20% of the Parent's Consolidated Net Tangible Assets;

(2)

the incurrence by the Parent or its Restricted Subsidiaries of the Existing Indebtedness;

(3)

(4)

the incurrence by the Parent or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Parent or such Restricted Subsidiary, including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease or refund any Indebtedness incurred pursuant to this clause (4), provided that after giving effect to any such incurrence, the principal amount of all Indebtedness incurred pursuant to this clause (4) and then outstanding does not exceed the greater of (a) $40.0 million or (b) 5.0% of the Parent's Consolidated Net Tangible Assets at such time;

(5)

the incurrence by the Parent or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to, extend, refinance, renew, replace, defease or refund Indebtedness that was permitted by the indenture to be incurred under the first paragraph of this covenant or clause (2) or (3) of this paragraph or this clause (5);

(6)

the incurrence by the Parent or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Parent and any of its Restricted Subsidiaries; provided, however, that:

(a): if the Parent is the obligor on such Indebtedness and a Subsidiary Guarantor or an Issuer is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the notes, or if a Subsidiary Guarantor or an Issuer is the obligor on such Indebtedness and neither the Parent nor another Subsidiary Guarantor or an Issuer is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the notes or the Guarantee of such Guarantor; and
(b): (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Parent or a Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Parent nor a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Parent or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

Table of Contents

(7)

the incurrence by the Parent or any of its Restricted Subsidiaries of obligations under Hedging Contracts in the ordinary course of business and not for speculative purposes;

the guarantee by the Parent or any of its Restricted Subsidiaries of Indebtedness of the Parent or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this covenant;

(9)

the incurrence by the Parent or any of its Restricted Subsidiaries of obligations relating to net Hydrocarbon balancing positions arising in the ordinary course of business and consistent with past practice;

(11)

(b): any sale or other transfer of any such preferred securities to a Person that is not either the Parent or a Restricted Subsidiary of the Parent shall be deemed, in each case, to constitute an issuance of such preferred securities by such Restricted Subsidiary that was not permitted by this clause (11);

(12)

the incurrence by the Parent or any of its Restricted Subsidiaries of Acquired Debt in connection with a merger or consolidation meeting either one of the financial tests set forth in clause (4) under the caption "—Merger, Consolidation or Sale of Assets";

(13)

the incurrence by the Parent or any of its Restricted Subsidiaries of liability in respect of the Indebtedness of any Unrestricted Subsidiary of the Parent or any Joint Venture but only to the extent that such liability is the result of the Parent's or any such Restricted Subsidiary's being a general partner of such Unrestricted Subsidiary or Joint Venture and not as a guarantor of such Indebtedness and provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (13) and then outstanding does not exceed $25.0 million; and

(14)

the incurrence by the Parent or any of its Restricted Subsidiaries of additional Indebtedness, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (14) and then outstanding does not exceed the greater of (a) $40.0 million or (b) 5.0% of the Parent's Consolidated Net Tangible Assets.

For purposes of determining compliance with this "Incurrence of Indebtedness and Issuance of Preferred Securities" covenant, in the event that an item of Indebtedness (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (14) above, or is entitled to be incurred pursuant to the first paragraph of this covenant, the Parent will be permitted to classify (or later classify or reclassify in whole or in part in its sole discretion) such item of Indebtedness in any manner that complies with this covenant. Any Indebtedness under the Credit Agreement on the date of the indenture shall be considered incurred under clause (1) of the second paragraph of this covenant.

Table of Contents

The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this covenant, provided, in each such case, that the amount thereof is included in Fixed Charges of the Parent as accrued. Further, the accounting reclassification of any obligation of the Parent or any of its Restricted Subsidiaries as Indebtedness will not be deemed an incurrence of Indebtedness for purposes of this covenant.

Liens

The Parent will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired, unless the notes or any Guarantee of Parent or such Restricted Subsidiary, as applicable, is secured on an equal and ratable basis with (or on a senior basis to, in the case of obligations subordinated in right of payment to the notes or such Guarantee, as the case may be) the obligations so secured until such time as such obligations are no longer secured by a Lien.

Dividend and Other Payment Restrictions Affecting Subsidiaries

The Parent will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1): pay dividends or make any other distributions on its Capital Stock to the Parent or any of its Restricted Subsidiaries, or pay any Indebtedness or other obligations owed to the Parent or any of its Restricted Subsidiaries;
(2): make loans or advances to the Parent or any of its Restricted Subsidiaries; or
(3): transfer any of its properties or assets to the Parent or any of its Restricted Subsidiaries.

However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(1): agreements as in effect on the date of the indenture and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements or the Indebtedness to which they relate, provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are no more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the date of the indenture;
(2): the indenture, the notes and the Guarantees;
(3): applicable law;
(4): any instrument governing Indebtedness or Capital Stock of a Person acquired by the Parent or any of its Restricted Subsidiaries as in effect at the time of such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was otherwise permitted by the terms of the indenture to be incurred;

Table of Contents

(5): customary non-assignment provisions in Hydrocarbon purchase and sale or exchange agreements or similar operational agreements or in licenses, easements or leases, in each case entered into in the ordinary course of business and consistent with past practices;
(6): Capital Lease Obligations, mortgage financings or purchase money obligations, in each case for property acquired in the ordinary course of business that impose restrictions on that property of the nature described in clause (3) of the preceding paragraph;
(7): any agreement for the sale or other disposition of a Restricted Subsidiary of the Parent that restricts distributions by that Restricted Subsidiary pending its sale or other disposition;
(8): Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;
(9): Liens securing Indebtedness otherwise permitted to be incurred under the provisions of the covenant described above under the caption "—Liens" that limit the right of the debtor to dispose of the assets subject to such Liens;
(10): provisions with respect to the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business;
(11): any agreement or instrument relating to any property or assets acquired after the date of the indenture, so long as such encumbrance or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisitions;
(12): restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;
(13): any instrument governing Indebtedness of an FERC Subsidiary, provided that such Indebtedness was otherwise permitted by the terms of the indenture to be incurred;
(14): the issuance of preferred securities by a Restricted Subsidiary of the Parent or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred securities is permitted pursuant to the covenant described above under the caption "—Incurrence of Indebtedness and Issuance of Preferred Securities" and the terms of such preferred securities do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred securities prior to paying any dividends or making any other distributions on such other Capital Stock); and
(15): any other agreement governing Indebtedness of the Parent, Issuers or any Subsidiary Guarantor that is permitted to be incurred by the covenant described under "—Incurrence of Indebtedness and Issuance of Preferred Securities"; provided, however, that such encumbrances or restrictions are not materially more restrictive, taken as a whole, than those contained in the indenture or the Credit Agreement as it exists on the date of the indenture.

Merger, Consolidation or Sale of Assets

None of the Issuers or the Parent may, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not such Issuer or the Parent is the survivor); or (2) sell, assign, transfer,

Table of Contents

lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions, to another Person, unless:

(1)

either: (a) such Issuer or Parent, as applicable, is the survivor; or (b) the Person formed by or surviving any such consolidation or merger (if other than such Issuer or Parent, as applicable) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a Person organized or existing under the laws of the United States, any state of the United States or the District of Columbia; provided, however, that Finance Corp. may not consolidate or merge with or into any Person other than a corporation satisfying such requirement so long as the Company is not a corporation;

(2)

the Person formed by or surviving any such consolidation or merger (if other than such Issuer or the Parent, as applicable) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made assumes all the obligations of such Issuer or the Parent, as applicable, under the notes, the indenture, the registration rights agreement and the Parent's Guarantee of the notes, if applicable, pursuant to agreements reasonably satisfactory to the trustee;

(3)

immediately after such transaction no Default or Event of Default exists;

(4)

in the case of a transaction involving the Parent, either

(a): the Parent, or the Person formed by or surviving any such consolidation or merger (if other than the Parent), or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made will, on the date of such transaction after giving pro forma effect thereto and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of the covenant described above under the caption "—Incurrence of Indebtedness and Issuance of Preferred Securities"; or
(b): immediately after giving effect to such transaction on a pro forma basis and any related financing transactions as if the same had occurred at the beginning of the applicable four-quarter period, the Fixed Charge Coverage Ratio of the Parent, or the Person formed by or surviving any such consolidation or merger (if other than the Parent), or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made, will be equal to or greater than the Fixed Charge Coverage Ratio of the Parent immediately before such transactions; and

(5)

such Issuer or the Parent has delivered to the trustee an officers' certificate and an opinion of counsel, each stating that such consolidation, merger or disposition and such supplemental indenture (if any) comply with the indenture.

The restrictions described in the foregoing clause (4) will not apply to (a) any consolidation or merger of the Parent with or into one of its Restricted Subsidiaries for any purpose or (b) any sale, assignment, transfer, conveyance, lease or other disposition of properties or assets of a Restricted Subsidiary (other than Finance Corp.) to the Parent, the Company or another Restricted Subsidiary that is a Subsidiary Guarantor.

Notwithstanding the second preceding paragraph, the Parent and the Company are permitted to reorganize as any other form of entity in accordance with the following procedures provided that:

(1): the reorganization involves the conversion (by merger, sale, contribution or exchange of assets or otherwise) of the Parent or the Company into a form of entity other than a limited partnership formed under Delaware law;

Table of Contents

(2): the entity so formed by or resulting from such reorganization is an entity organized or existing under the laws of the United States, any state thereof or the District of Columbia;
(3): the entity so formed by or resulting from such reorganization assumes all the obligations of the Parent under its Guarantee of the notes or the Company under the notes, as applicable, the indenture and the registration rights agreement pursuant to agreements reasonably satisfactory to the trustee;
(4): immediately after such reorganization no Default or Event of Default exists; and
(5): such reorganization is not materially adverse to the Holders or Beneficial Owners of the notes (for purposes of this clause (5) a reorganization will not be considered materially adverse to the Holders or Beneficial Owners of the notes solely because the successor or survivor of such reorganization (a) is subject to federal or state income taxation as an entity or (b) is considered to be an "includible corporation" of an affiliated group of corporations within the meaning of Section 1504(b) of the Code or any similar state or local law).

Notwithstanding anything in the indenture to the contrary, in the event the Company becomes a corporation or the Company or the Person formed by or surviving any consolidation or merger (permitted in accordance with the terms of the indenture) is a corporation, Finance Corp. may be merged into the Company or it may be dissolved and cease to be an Issuer.

Upon compliance with the foregoing requirements with respect to any consolidation or merger or any sale, assignment, transfer, conveyance, lease or other disposition of all or substantially all of the properties or assets of an Issuer Parent in accordance with the foregoing in which such Issuer or Parent is not the surviving entity, the surviving Person formed by such consolidation or into or with which such Issuer or Parent is merged or to which such sale, assignment, transfer, conveyance, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, such Issuer or Parent, as applicable, under the indenture with the same effect as if such surviving Person had been named as such Issuer or Parent in the indenture, and thereafter (except in the case of a lease of all or substantially all of such Issuer's properties or assets), such Issuer or Parent, as applicable, will be relieved of all obligations and covenants under the indenture and the notes or its Guarantee. Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve "all or substantially all" of the properties or assets of a Person.

Transactions with Affiliates

The Parent will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an "Affiliate Transaction"), unless:

•: the Affiliate Transaction is on terms that are no less favorable to the Parent or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of the Parent, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Parent or the relevant Restricted Subsidiary from a financial point of view; and
•: the Parent delivers to the trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, a resolution of the Board of Directors of the Parent set forth in an officers' certificate certifying that such

Table of Contents

Affiliate Transaction complies with this covenant and that such Affiliate Transaction or series of related Affiliate Transactions has been approved by a majority of the disinterested members of the Board of Directors.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph:

(1): any transaction or series of related transactions involving aggregate consideration of less than $1.0 million;
(2): any employment, equity award, equity option or equity appreciation agreement or plan entered into by the Parent or any of its Restricted Subsidiaries in the ordinary course of business;
(3): transactions between or among any of the Parent and its Restricted Subsidiaries;
(4): transactions with a Person (other than an Unrestricted Subsidiary of the Parent) that is an Affiliate of the Parent solely because the Parent owns an Equity Interest in such Person;
(5): transactions effected in accordance with the terms of agreements that are identified in the indenture, in each case as such agreements are in effect on the date of the indenture, and any amendment or replacement of any of such agreements so long as such amendment or replacement agreement is no less advantageous to the Parent in any material respect than the agreement so amended or replaced;
(6): customary compensation, indemnification and other benefits made available to officers, directors or employees of the Parent or a Restricted Subsidiary or Affiliate of the Parent, including reimbursement or advancement of out-of-pocket expenses and provisions of officers' and directors' liability insurance;
(7): sales of Equity Interests (other than Disqualified Stock) to Affiliates of the Parent;
(8): Permitted Investments or Restricted Payments that are permitted by the provisions of the indenture described above under the caption "—Restricted Payments";
(9): payments to the General Partner with respect to reimbursement for expenses in accordance with the Partnership Agreement as in effect on the date of the indenture and as it may be amended, provided that any such amendment is not less favorable to the Parent in any material respect than the agreement prior to such amendment;
(10): transactions between the Parent or any of its Restricted Subsidiaries and any other Person, a director of which is also on the Board of Directors of the Parent or any direct or indirect parent company of the Parent, and such common director is the sole cause for such other Person to be deemed an Affiliate of the Parent or any of its Restricted Subsidiaries; provided, however, that such director abstains from voting as a member of the Board of Directors of the Parent or any direct or indirect parent company of the Parent, as the case may be, on any transaction with such other Person; and
(11): in the case of contracts for gathering, transporting, treating, processing, marketing, distributing, storing or otherwise handling Hydrocarbons, or activities or services reasonably related or ancillary thereto, or other operational contracts, any such contracts are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Parent or any Restricted Subsidiary and third parties, or if neither the Parent or any Restricted Subsidiary has entered into a similar contract with a third party, then the terms are no less favorable than those available from third parties on an arm's-length basis.

Designation of Restricted and Unrestricted Subsidiaries

The Board of Directors of the Parent may designate any Restricted Subsidiary of the Parent to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary of the Parent is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Parent and its Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be either an Investment made as of the time of the designation that will reduce the amount available for Restricted Payments under the first paragraph of the covenant described above under the caption "—Restricted Payments" or represent Permitted Investments, as determined by the Parent. That designation will only be permitted if the Investment would be permitted at that time and if the Subsidiary so designated otherwise meets the definition of an Unrestricted Subsidiary.

The Board of Directors of the Parent may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary, provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Parent of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under the covenant described above under the caption "—Incurrence of Indebtedness and Issuance of Preferred Securities," calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period, and (2) no Default or Event of Default would be in existence following such designation.

Additional Subsidiary Guarantees

If any Restricted Subsidiary of the Parent that is not already a Guarantor guarantees any Indebtedness of either of the Issuers or any Guarantor under any Credit Facility, then that Subsidiary will become a Guarantor by executing a supplemental indenture and delivering it to the trustee within 20 Business Days of the date on which it guaranteed such Indebtedness; provided, however, that the preceding shall not apply to Subsidiaries of the Parent that have properly been designated as Unrestricted Subsidiaries in accordance with the indenture for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Guarantee of a Restricted Subsidiary that was incurred pursuant to this paragraph will be released in the circumstances described under "—Guarantees."

Sale and Leaseback Transactions

The Parent will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided, however, that the Parent or any of its Restricted Subsidiaries may enter into a sale and leaseback transaction if:

(1): the Parent or that Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the Fixed Charge Coverage Ratio test in the first paragraph of the covenant described above under the caption "—Incurrence of Indebtedness and Issuance of Preferred Securities" and (b) incurred a Lien to secure such Indebtedness pursuant to the covenant described above under the caption "—Liens;"
(2): the gross cash proceeds of that sale and leaseback transaction are at least equal to the fair market value, as determined in accordance with the definition of that term and set forth in an officers' certificate delivered to the trustee, of the property that is the subject of that sale and leaseback transaction; and

Table of Contents

(3): the transfer of assets in that sale and leaseback transaction is permitted by, and the Parent applies the proceeds of such transaction in compliance with, the covenant described above under the caption "—Repurchase at the Option of Holders—Asset Sales."

Business Activities

The Parent will not, and will not permit any Restricted Subsidiary to, engage in any business other than a Permitted Business, except to such extent as would not be material to the Parent and its Restricted Subsidiaries taken as a whole.

Finance Corp. may not incur Indebtedness unless (1) the Company or the Parent is a co-obligor or guarantor of such Indebtedness or (2) the net proceeds of such Indebtedness are loaned to the Company or the Parent, used to acquire outstanding debt securities issued by the Company or the Parent or used to repay Indebtedness of the Company or the Parent as permitted under the covenant described about under the caption "—Incurrence of Indebtedness and Issuance of Preferred Securities." Finance Corp. may not engage in any business not related directly or indirectly to obtaining money or arranging financing for the Parent or its Restricted Subsidiaries.

Reports

Whether or not required by the Commission, so long as any notes are outstanding, the Parent will file with the Commission for public availability within the time periods specified in the Commission's rules and regulations (unless the Commission will not accept such a filing), and the Parent will furnish to the trustee and, upon its prior request, to any of the Holders or Beneficial Owners of notes, within five Business Days of filing, or attempting to file, the same with the Commission:

(1) all quarterly and annual financial and other information with respect to the Parent and its Subsidiaries that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Parent were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report on the annual financial statements by the Parent's certified independent accountants; and

(2) all current reports that would be required to be filed with the Commission on Form 8-K if the Parent were required to file such reports.

The availability of the foregoing information or reports on the Commission's website will be deemed to satisfy the foregoing delivery requirements.

If the Parent has designated any of its Subsidiaries as Unrestricted Subsidiaries, then, to the extent material, the quarterly and annual financial information required by the second preceding paragraph will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management's Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Parent and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries of the Parent.

In addition, the Company and the Guarantors have agreed that, for so long as any notes remain outstanding, they will furnish to the Holders and Beneficial Owners of the notes and to securities analysts and prospective investors in the notes, upon their request, the information required to be delivered pursuant to Rule l44A(d)(4) under the Securities Act.

Covenant Termination

If at any time (a) the rating assigned to the notes by both S&P and Moody's is an Investment Grade Rating, (b) no Default has occurred and is continuing under the indenture and (c) the Issuers have delivered to the trustee an officers' certificate certifying to the foregoing provisions of this sentence, the Parent and its Restricted Subsidiaries will no longer be subject to the provisions of the indenture described above under the caption "—Repurchase at the Option of Holders—Asset Sales" and the following provisions of the indenture described above under the caption "—Certain Covenants":

•: "—Restricted Payments,"

Events of Default and Remedies

Each of the following is an Event of Default:

(1): default for 30 days in the payment when due of interest on the notes;
(2): default in payment when due of the principal of, or premium, if any, on the notes;
(3): failure by the Issuers or the Parent to comply with the provisions described under the captions "—Repurchase at the Option of Holders—Asset Sales," "—Repurchase at the Option of Holders—Change of Control" or "—Certain Covenants—Merger, Consolidation or Sale of Assets";
(4): failure by the Parent for 180 days after notice to comply with the provisions described under "—Certain Covenants—Reports";
(5): failure by the Issuers or the Parent for 30 days after notice to comply with any of their other agreements in the indenture;
(6): default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Parent or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Parent or

Table of Contents

any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or is created after the date of the indenture, if that default:

(a): is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (a "Payment Default"); or
(b): results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; provided, however, that if, prior to any acceleration of the notes, (i) any such Payment Default is cured or waived, (ii) any such acceleration is rescinded, or (iii) such Indebtedness is repaid during the 10 business day period commencing upon the end of any applicable grace period for such Payment Default or the occurrence of such acceleration, as the case may be, any Default or Event of Default (but not any acceleration of the notes) caused by such Payment Default or acceleration shall be automatically rescinded, so long as such rescission does not conflict with any judgment, decree or applicable law;

(7): failure by the Parent or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $20.0 million (to the extent not covered by insurance by a reputable and creditworthy insurer as to which the insurer has not disclaimed coverage), which judgments are not paid, discharged or stayed for a period of 60 days;
(8): except as permitted by the indenture, any Guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Guarantee; and
(9): certain events of bankruptcy, insolvency or reorganization described in the indenture with respect to Finance Corp., the Company, the Parent or any of the Parent's Restricted Subsidiaries that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary of the Parent.

In the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization, with respect to Finance Corp., the Company, the Parent, any Restricted Subsidiary of the Parent that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary of the Parent, all outstanding notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the trustee or the Holders of at least 25% in principal amount of the then outstanding notes may declare all the notes to be due and payable immediately.

Holders of the notes may not enforce the indenture or the notes except as provided in the indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding notes may direct the trustee in its exercise of any trust or power. The trustee may withhold notice of any continuing Default or Event of Default from Holders of the notes if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal of, or interest or premium, if any, on, the notes.

Subject to the provisions of the indenture relating to the duties of the trustee in case an Event of Default occurs and is continuing, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any holders of the notes unless such holders have offered to the trustee reasonable indemnity or security against any loss, liability or expense.

Table of Contents

Except to enforce the right to receive payment of principal, premium, if any, or interest, if any, when due, no Holder of a note may pursue any remedy with respect to the indenture or the notes unless:

(1): such Holder has previously given the trustee written notice that an Event of Default is continuing;
(2): Holders of at least 25% in aggregate principal amount of the then outstanding notes make a written request to the trustee to pursue the remedy;
(3): such Holder or Holders offer and, if requested, provide to the trustee security or indemnity reasonably satisfactory to the trustee against any loss, liability or expense;
(4): the trustee does not comply with such request within 60 days after receipt of the request and the offer of security or indemnity; and
(5): during such 60 day period, holders of a majority in aggregate principal amount of the then outstanding notes do not give the trustee a direction inconsistent with such request.

The Holders of a majority in principal amount of the notes then outstanding by notice to the trustee may on behalf of the Holders of all of the notes waive any existing Default or Event of Default and its consequences under the indenture except a continuing Default or Event of Default in the payment of principal of, or interest or premium, if any, on, the notes.

The Issuers are required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon any officer of the General Partner or Finance Corp. becoming aware of any Default or Event of Default, the Issuers are required to deliver to the trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Unitholders and No Recourse to General Partner

None of the General Partner or any director, officer, partner, employee, incorporator, manager or unitholder or other owner of Capital Stock of the General Partner, Issuers or any Guarantor, as such, will have any liability for any obligations of the Issuers or any Guarantor under the notes, the indenture or the Guarantees, or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

The Issuers may, at their option and at any time, elect to have all of their obligations discharged with respect to the outstanding notes and all obligations of the Guarantors discharged with respect to their Guarantees ("Legal Defeasance"), except for:

(1): the rights of Holders of outstanding notes to receive payments in respect of the principal of, and interest or premium, if any, on, such notes when such payments are due from the trust referred to below;
(2): the Issuers' obligations with respect to the notes concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment and money for security payments held in trust;
(3): the rights, powers, trusts, duties and immunities of the trustee, and the Issuers' obligations in connection therewith; and
(4): the Legal Defeasance provisions of the indenture.

Table of Contents

In addition, the Issuers may, at their option and at any time, elect to have their obligations released with respect to certain covenants that are described in the indenture ("Covenant Defeasance") and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, insolvency or reorganization events) described under "—Events of Default and Remedies" will no longer constitute an Event of Default with respect to the notes. If the Issuers exercise either their Legal Defeasance or Covenant Defeasance option, each Guarantor will be released and relieved of any obligations under its Guarantee and any security for the notes (other than the trust) will be released.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1)

the Issuers must irrevocably deposit with the trustee, in trust, for the benefit of the Holders of the notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, and interest and premium, if any, on, the outstanding notes on the date of fixed maturity or on the applicable redemption date, as the case may be, and the Issuers must specify whether the notes are being defeased to the date of fixed maturity or to a particular redemption date; provided that if such redemption is made as provided in the second paragraph under "—Optional Redemption," (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Make Whole Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money in trust on the redemption date as necessary to pay the Make Whole Premium as determined on such date;

(2)

in the case of Legal Defeasance, the Issuers must deliver to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that:

(a): the Issuers have received from, or there has been published by, the Internal Revenue Service a ruling; or
(b): since the date of the indenture, there has been a change in the applicable federal income tax law,

in either case to the effect that, and based thereon such opinion of counsel will confirm that, the Holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3): in the case of Covenant Defeasance, the Issuers must deliver to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that the Holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;
(4): no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit);
(5): such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the indenture) to

Table of Contents

which the Parent or any of its Subsidiaries is a party or by which the Parent or any of its Subsidiaries is bound;

(6): the Issuers must deliver to the trustee an officers' certificate stating that the deposit was not made by the Issuers with the intent of preferring the Holders of notes over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding creditors of the Issuers or others; and
(7): the Issuers must deliver to the trustee an officers' certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Amendment, Supplement and Waiver

Except as provided in the next two succeeding paragraphs, the indenture or the notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the then outstanding notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes), and any existing default or compliance with any provision of the indenture or the notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes).

Without the consent of each Holder affected, an amendment, supplement or waiver may not (with respect to any notes held by a non-consenting Holder):

(1): reduce the principal amount of notes whose Holders must consent to an amendment, supplement or waiver;
(2): reduce the principal of or change the fixed maturity of any note or alter the provisions with respect to the redemption or repurchase of the notes (other than provisions relating to the covenants described above under the caption "—Repurchase at the Option of Holders");
(3): reduce the rate of or change the time for payment of interest on any note;
(4): waive a Default or Event of Default in the payment of principal of, or interest or premium, if any, on the notes (except a rescission of acceleration of the notes by the Holders of at least a majority in principal amount of the notes and a waiver of the payment default that resulted from such acceleration);
(5): make any note payable in currency other than that stated in the notes;
(6): make any change in the provisions of the indenture relating to waivers of past Defaults or the rights of Holders of notes to receive payments of principal of, or interest or premium, if any, on the notes (other than as permitted in clause (7) below);
(7): waive a redemption or repurchase payment with respect to any note (other than a payment required by one of the covenants described above under the caption "—Repurchase at the Option of Holders");
(8): release any Guarantor from any of its obligations under its Guarantee or the indenture, except in accordance with the terms of the indenture; or
(9): make any change in the preceding amendment, supplement and waiver provisions.

Notwithstanding the preceding, without the consent of any Holder of notes, the Issuers, the Guarantors and the trustee may amend or supplement the indenture or the notes:

(1): to cure any ambiguity, defect or inconsistency;
(2): to provide for uncertificated notes in addition to or in place of certificated notes;

Table of Contents

(3): to provide for the assumption of an Issuer's obligations to Holders of notes in the case of a merger or consolidation or sale of all or substantially all of such Issuer's properties or assets;
(4): to make any change that would provide any additional rights or benefits to the Holders of notes or that does not adversely affect the legal rights under the indenture of any such Holder, provided that any change to conform the indenture to this prospectus will be deemed to not adversely affect such legal rights;
(5): to secure the notes or the Guarantees pursuant to the requirements of the covenant described above under the subheading "—Certain Covenants—Liens";
(6): to provide for the issuance of additional notes in accordance with the limitations set forth in the indenture;
(7): to add any additional Guarantor or to evidence the release of any Guarantor from its Guarantee, in each case as provided in the indenture;
(8): to comply with requirements of the Commission in order to effect or maintain the qualification of the indenture under the Trust Indenture Act; or
(9): to evidence or provide for the acceptance of appointment under the indenture of a successor trustee.

Neither the Parent nor any of its Subsidiaries shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Beneficial Owner or Holder of any notes for or as an inducement to any consent to any waiver, supplement or amendment of any terms or provisions of the indenture or the notes, unless such consideration is offered to be paid or agreed to be paid to all Beneficial Owners and Holders of the notes which so consent in the time frame set forth in solicitation documents relating to such consent.

Satisfaction and Discharge

The indenture will be discharged and will cease to be of further effect as to all notes issued thereunder (except as to surviving rights of registration of transfer or exchange of the notes and as otherwise specified in the indenture), when:

(1)

either:

(a): all notes that have been authenticated, except lost, stolen or destroyed notes that have been replaced or paid and notes for whose payment money has been deposited in trust and thereafter repaid to the Issuers, have been delivered to the trustee for cancellation; or
(b): all notes that have not been delivered to the trustee for cancellation have become due and payable or will become due and payable within one year by reason of the mailing of a notice of redemption or otherwise and the Issuers or any Guarantor has irrevocably deposited or caused to be deposited with the trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the notes not delivered to the trustee for cancellation for principal, premium, if any, and accrued interest to the date of fixed maturity or redemption; provided that if such redemption is made as provided in the second paragraph under "—Optional Redemption," (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Make Whole Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or

Table of Contents

cause to be deposited additional money in trust on the redemption date as necessary to pay the Make Whole Premium as determined by such date;

(2): no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than the indenture) to which the Parent or any of its Subsidiaries is a party or by which the Parent or any of its Subsidiaries is bound;
(3): the Issuers or any Guarantor has paid or caused to be paid all sums payable by it under the indenture; and
(4): the Issuers have delivered irrevocable instructions to the trustee to apply the deposited money toward the payment of the notes at fixed maturity or the redemption date, as the case may be.

In addition, the Issuers must deliver an officers' certificate and an opinion of counsel to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Concerning the Trustee

U.S. Bank National Association is the trustee under the indenture. If the trustee becomes a creditor of an Issuer or any Guarantor, the indenture limits its right 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 will be permitted to engage in other transactions; however, if it acquires any conflicting interest (as defined in the Trust Indenture Act) after a Default has occurred and is continuing, it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as trustee (if the indenture has been qualified under the Trust Indenture Act) or resign.

The Holders of a majority in principal amount of the then outstanding notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that in case an Event of Default occurs and is continuing, the trustee will be required, in the exercise of its powers, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any Holder of notes, unless such Holder has offered to the trustee security or indemnity satisfactory to it against any loss, liability or expense.

Governing Law

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

Additional Information

Anyone who receives this prospectus may obtain a copy of the indenture without charge by writing to Summit Midstream Holdings, LLC, 2100 McKinney Avenue, Suite 1250, Dallas, Texas 75201, Attention: Chief Financial Officer.

Book-Entry, Delivery and Form

The new notes will be issued initially only in the form of one or more global notes (collectively, the "Global Notes"). The Global Notes will be deposited upon issuance with the trustee as custodian for DTC, and registered in the name of DTC's nominee, Cede & Co., in each case for credit to an account of a direct or indirect participant in DTC that has exchanged old notes for new notes in the exchange offer, as described below. Beneficial interests in the Global Notes may be held through the

Table of Contents

Euroclear System ("Euroclear") and Clearstream Banking, S.A. ("Clearstream") (as indirect participants in DTC).

The Global Notes may be transferred, in whole but not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in registered, certificated form ("Certificated Notes") except in the limited circumstances described below. See "—Exchange of Global Notes for Certificated Notes."

Depository Procedures

The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. The Issuers take no responsibility for these operations and procedures and urge investors to contact the system or their participants directly to discuss these matters.

DTC has advised the Issuers that DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the "Participants") and to facilitate the clearance and settlement of transactions in those securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Access to DTC's system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the "Indirect Participants"). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants.

DTC has also advised the Issuers that, pursuant to procedures established by it:

(1) upon deposit of the Global Notes, DTC will credit the accounts of Participants designated by the exchange agent with portions of the principal amount of the Global Notes; and

(2) ownership of these interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interests in the Global Notes).

Investors in the Global Notes who are Participants in DTC's system may hold their interests therein directly through DTC. Investors in the Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants in such system. Euroclear and Clearstream may hold interests in the Global Notes on behalf of their participants through customers' securities accounts in their respective names on the books of their depositories, which are Euroclear Bank S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of such systems.

The laws of some states require that certain Persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such Persons will be limited to that extent. Because DTC can act only on behalf of Participants, which in turn act on behalf of Indirect Participants, the ability of a Person having beneficial interests in a Global Note to pledge such interests to Persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

Table of Contents

Except as described below, owners of beneficial interests in the Global Notes will not have notes registered in their names, will not receive physical delivery of Certificated Notes and will not be considered the registered owners or "Holders" thereof under the indenture for any purpose.

Payments in respect of the principal of, and interest and premium, if any, on, a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered Holder under the indenture. Under the terms of the indenture, the Issuers, the Guarantors and the trustee will treat the Persons in whose names the notes, including the Global Notes, are registered as the owners of the notes for the purpose of receiving payments and for all other purposes. Consequently, neither the Issuers, the Guarantors, the trustee nor any agent of an Issuer or the trustee has or will have any responsibility or liability for:

(1): any aspect of DTC's records or any Participant's or Indirect Participant's records relating to or payments made on account of beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC's records or any Participant's or Indirect Participant's records relating to the beneficial ownership interests in the Global Notes; or
(2): any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants.

DTC has advised the Issuers that its current practice, at the due date of any payment in respect of securities such as the notes, is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the notes as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustee or the Issuers. Neither the Issuers nor the trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the notes, and the Issuers and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between Participants in DTC will be effected in accordance with DTC's procedures, and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

Cross-market transfers between the Participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC's rules on behalf of Euroclear or Clearstream, as the case may be, by its depository; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depository to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

DTC has advised the Issuers that it will take any action permitted to be taken by a Holder of notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have given such direction. However, if there is an Event of Default under the notes, DTC reserves the right to exchange the Global Notes for Certificated Notes, and to distribute such notes to its Participants.

Table of Contents

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. None of the Issuers, the trustee or any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Exchange of Global Notes for Certificated Notes

A Global Note is exchangeable for Certificated Notes in minimum denominations of $2,000 and in integral multiples of $1,000 in excess of $2,000, if:

(1): DTC (a) notifies the Issuers that it is unwilling or unable to continue as depositary for the Global Note or (b) has ceased to be a clearing agency registered under the Exchange Act and in either event the Issuers fail to appoint a successor depositary within 90 days; or
(2): there has occurred and is continuing an Event of Default and DTC notifies the trustee of its decision to exchange the Global Note for Certificated Notes.

Beneficial interests in a Global Note may also be exchanged for Certificated Notes in the other limited circumstances permitted by the indenture, including if an affiliate of ours acquires such interests. In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Exchange of Certificated Notes for Global Notes

Certificated Notes may not be exchanged for beneficial interests in any Global Note, except in the limited circumstances provided in the indenture.

Same-Day Settlement and Payment

The Issuers will make payments in respect of the notes represented by the Global Notes (including principal, premium, if any, and interest) by wire transfer of immediately available funds to the accounts specified by the Global Note Holder. The Issuers will make all payments of principal, interest and premium, if any, with respect to Certificated Notes by wire transfer of immediately available funds to the accounts specified by the Holders of the Certificated Notes or, if no such account is specified, by mailing a check to each such Holder's registered address. The notes represented by the Global Notes are eligible to trade in DTC's Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. The Issuers expect that secondary trading in any Certificated Notes will also be settled in immediately available funds.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised the Issuers that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date.

If the Parent or any Restricted Subsidiary of the Parent sells or otherwise disposes of any Equity Interests of any direct or indirect Restricted Subsidiary of the Parent such that, after giving effect to any such sale or disposition, such Person is no longer a Restricted Subsidiary of the Parent, the Parent will be deemed to have made an Investment on the date of any such sale or disposition in an amount equal to the fair market value of the Equity Interests of such Restricted Subsidiary not sold or disposed of in an amount determined as provided in the final paragraph of the covenant described above under the caption "—Certain Covenants—Restricted Payments."

MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES

The following discussion summarizes certain U.S. federal income tax considerations relevant to the exchange of the old notes for the new notes pursuant to the exchange offer, but does not purport to be a complete analysis of all potential tax effects relating thereto. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (the "Code"), applicable U.S. Treasury Regulations promulgated thereunder, judicial authority and administrative interpretations, as of the date hereof, all of which are subject to change, possibly with retroactive effect, or are subject to different interpretations. We cannot assure you that the Internal Revenue Service (the "IRS") will not challenge one or more of the tax consequences described in this discussion, 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 statements made and conclusions reached in the following discussion. The discussion does not address all of the U.S. federal income tax consequences that may be important to a particular holder in light of the holder's circumstances, or to certain categories of investors that may be subject to special rules, such as dealers in securities or currencies, traders in securities that have elected the mark-to-market method of accounting for their securities, holders of notes who are U.S. persons and whose functional currency is not the U.S. dollar, persons holding notes as part of a hedge, straddle, conversion or other "synthetic security" or integrated transaction, U.S. expatriates, financial institutions, insurance companies, regulated investment companies, real estate investment trusts, persons subject to the alternative minimum tax, entities that are tax-exempt for U.S. federal income tax purposes, and partnerships and other pass-through entities and holders of interests therein.

Holders of new notes should consult their tax advisors with regard to the application of the tax consequences discussed below to their particular situations as well as the application of any, state, local, foreign, or other tax laws, including gift and estate tax laws, and any tax treaties.

Exchange Pursuant to the Exchange Offer

We believe that the exchange of new notes for old notes pursuant to the exchange offer will not be a taxable exchange for U.S. federal income tax purposes. Accordingly, a holder will not recognize any taxable gain or loss as a result of the exchange. The new notes will have the same adjusted issue price as the old notes and a holder will have the same tax basis and holding period in the new notes as the holder had in the old notes immediately before the exchange.

Table of Contents

PLAN OF DISTRIBUTION

Based on interpretations by the staff of the SEC in no-action letters issued to third parties, we believe that you may transfer new notes issued in the exchange offer in exchange for the old notes if:

•: you acquire the new notes in the ordinary course of your business; and
•: you are not engaged in, and do not intend to engage in, and have no arrangement or understanding with any person to participate in, a distribution of such new notes.

You may not participate in the exchange offer if you are:

•: an "affiliate" of ours within the meaning of Rule 405 under the Securities Act; or
•: a broker-dealer that acquired old notes directly from us.

Each broker-dealer that receives new notes for its own account pursuant to the exchange offer must acknowledge that it will deliver this prospectus in connection with any resale of such new notes. To date, the staff of the SEC has taken the position that broker-dealers may fulfill their prospectus delivery requirements with respect to transactions involving an exchange of securities such as this exchange offer, other than a resale of an unsold allotment from the original sale of the old notes, with the prospectus contained in the registration statement relating to the exchange offer. On this basis, this prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for old notes where such old notes were acquired as a result of market-making activities or other trading activities. We have agreed that, for a period of up to 180 days after the exchange date (as such period may be extended), we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until such date, all dealers effecting transactions in new notes may be required to deliver this prospectus.

If you wish to exchange new notes for your old notes in the exchange offer, you will be required to make representations to us as described in "Exchange Offer—Procedures for Tendering—Your Representations to Us" in this prospectus. As indicated in the letter of transmittal, you will be deemed to have made these representations by tendering your old notes in the exchange offer. In addition, if you are a broker-dealer who receives new notes for your own account in exchange for old notes that were acquired by you as a result of market-making activities or other trading activities, you will be required to acknowledge, in the same manner, that you will deliver this prospectus in connection with any resale by you of such new notes.

We will not receive any proceeds from any sale of new notes by broker-dealers. New notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions:

•: in the over-the-counter market;
•: in negotiated transactions;
•: through the writing of options on the new notes; or
•: a combination of such methods of resale;

We refer you to the Prospectus, dated March 7, 2014 (the "Prospectus"), of Summit Midstream Holdings, LLC, a Delaware limited liability company ("Holdings") and a wholly owned subsidiary of Summit Midstream Partners, LP, a Delaware limited partnership (the "Partnership"), and Summit Midstream Finance Corp., a Delaware corporation and wholly owned subsidiary of the Partnership ("Finance Corp" and, together with Holdings, the "Issuers"), and this Letter of Transmittal (the "Letter of Transmittal"), which together describe the Issuers' offer (the "Exchange Offer") to exchange their Old Notes for a like aggregate principal amount of New Notes.

The Issuers reserve the right, at any time or from time to time, to extend the Exchange Offer at their discretion, in which event the term "Expiration Date" shall mean the latest date to which the Exchange Offer is extended. The Issuers shall notify the Exchange Agent orally or in writing of any extension. The Issuers will notify each registered holder of Old Notes of any extension by a press release issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

This Letter of Transmittal is to be used by holders of the Old Notes.

DTC participants that are accepting the Exchange Offer must transmit their acceptance to DTC, which will verify the acceptance and execute a book-entry delivery to the Exchange Agent's DTC account. DTC will then send a computer generated message known as an "agent's message" to the Exchange Agent for its acceptance. For you to validly tender your Old Notes in the Exchange Offer, the Exchange Agent must receive, prior to the Expiration Date, an agent's message under the ATOP procedures that confirms that:

•: DTC has received your instructions to tender your Old Notes; and
•: you agree to be bound by the terms of this Letter of Transmittal.

BY USING THE ATOP PROCEDURES TO TENDER OLD NOTES, YOU WILL NOT BE REQUIRED TO DELIVER THIS LETTER OF TRANSMITTAL TO THE EXCHANGE AGENT.
