• The possibility that our hedging activities may result in losses or may have a negative impact on our financial results;

• General economic, market and business conditions; and

• The occurrence of the risk factors listed elsewhere or incorporated by reference in this prospectus or any related prospectus supplement.

Consequently, all of the forward-looking statements made or incorporated by reference in this prospectus are qualified by these cautionary statements and there can be no assurance that the actual results or developments we anticipate will be realized or, even if substantially realized, that they will have the consequences for, or effects on, our business or operations that we anticipate today.

In addition, we refer to the notes to be issued in the exchange offer as the “New Notes” and the notes issued on March 15, 2017 as the “Old Notes.” We refer to the New Notes and the Old Notes collectively as the “Notes.” We sometimes refer to crude oil, natural gas, natural gas liquids (natural gas liquids, or “NGLs,” include ethane, propane, normal butane, iso-butane, and natural gasoline), refined petroleum products and liquid asphalt cement, collectively, as “petroleum products” or “products.”

Our Company

Overview

We are a growth-oriented provider of gathering, transportation, storage, distribution, marketing and other midstream services primarily to producers, refiners of petroleum products and other market participants located in the Gulf Coast, Midwest and Rocky Mountain regions of the U.S., Canada and the west coast of the United Kingdom (the “U.K.”). We, or our significant equity method investees, have an asset base consisting of pipelines, gathering systems, storage facilities, terminals, processing plants and other distribution assets located in North American production and supply areas, including the Gulf Coast, Midwest, Rocky Mountain, and Western Canadian regions. We also maintain and operate storage, terminal and marine facilities at Milford Haven in the U.K. that enable customers to supply petroleum products to markets in the Atlantic Basin. We also operate a network of liquid asphalt cement terminals throughout Mexico. Our operations are conducted directly and indirectly through our primary business segments: Crude Transportation, Crude Facilities, Crude Supply and Logistics, HFOTCO, SemGas^®, SemCAMS, SemLogistics and SemMexico.

Assets and Operations

We believe that the variety of our assets enables us to offer a broad portfolio of midstream services and helps mitigate seasonal fluctuations that may affect less diverse businesses. At September 30, 2017, our business segments owned the following:

• Crude Transportation operates crude oil pipelines and truck transportation businesses in the U.S. Crude Transportation’s assets include:

• a 450-mile crude oil gathering and transportation pipeline system with over 720,000 barrels of associated storage capacity in Kansas and northern Oklahoma that is connected to several third-party pipelines and refineries;

• the Wattenberg Oil Trunkline, a 75-mile, 12-inch diameter crude oil gathering pipeline system that transports crude oil from production facilities in the DJ Basin to the pipeline owned by White Cliffs Pipeline, L.L.C. (“White Cliffs”);

1

• a crude oil trucking fleet of over 245 transport trucks and 245 trailers;

• Maurepas Pipeline, consisting of three pipelines, with an approximate total of 106 miles, that service refineries in the Gulf Coast region;

• a 51% ownership interest in White Cliffs, which owns a 527-mile pipeline, consisting of two parallel 12-inch common carrier, crude oil pipelines, that transports crude oil from Platteville, Colorado to Cushing, Oklahoma (the “White Cliffs Pipeline”) that we operate; and

• a 50% ownership interest in Glass Mountain Pipeline, LLC (“Glass Mountain”), which owns a 215-mile crude oil pipeline in western and north central Oklahoma that we operate and is constructing a 44-mile pipeline extension into the STACK play in central Oklahoma. We sold our 50% interest in Glass Mountain on December 22, 2017.

• Crude Facilities operates a crude oil storage and terminal business in the U.S. Crude Facilities’ assets include:

• approximately 7.6 million barrels of crude oil storage capacity in Cushing, Oklahoma, of which 6.25 million barrels are leased to customers and 1.35 million barrels are used for crude oil operations, blending and marketing activities; and

• a 30-lane crude oil truck unloading facility with 350,000 barrels of associated storage capacity in Platteville, Colorado that connects to the origination point of the White Cliffs Pipeline.

• Crude Supply and Logistics operates a crude oil marketing business that utilizes our Crude Transportation and Crude Facilities assets for marketing purposes. Additionally, Crude Supply and Logistics’ assets include approximately 61,800 barrels of crude oil storage capacity in Trenton and Stanley, North Dakota.

• HFOTCO, acquired in July 2017, operates a large terminal facility located on the U.S. Gulf Coast. HFOTCO’s assets include:

• approximately 16.8 million barrels of product storage with crude pipeline connectivity to the local refining complex, deep water marine access and inbound crude receipt pipeline connectivity, as well as rail and truck loading and unloading capabilities; and

• 330 acres on the Houston Ship Channel.

• SemGas provides natural gas gathering, processing and marketing services in the U.S. and owns and operates gathering systems and four natural gas processing plants with a combined operating capacity of 595 million cubic feet per day. SemGas is building a 50-mile, 200 million cubic feet per day natural gas pipeline to connect our northern Oklahoma processing facilities to the STACK play in central Oklahoma (the “Canton Pipeline”), which became operational in late fourth quarter of 2017. The Canton Pipeline is backed by firm commitments from an investment grade counterparty as well as a long-term gathering and processing agreement with dedicated acreage. With additional compression, the Canton Pipeline could be expanded up to 400 million cubic feet per day to serve other producers in the area.

• SemCAMS provides natural gas gathering and processing services in Alberta, Canada and owns working interests in, and operates, four natural gas processing plants with a combined operating capacity of 695 million cubic feet per day. SemCAMS is constructing a sour gas processing plant in the Wapiti area of the Montney play in Alberta with a capacity of 200 million cubic feet per day, which is expected to be completed in the second quarter of 2019. SemCAMS has also announced plans to build a new sour gas facility to process sour Montney gas in the Pipestone region of the Western Canadian Sedimentary Basin, the first stage of which will have capacity to process 60 million cubic feet per day, and which is expected to be operational in the fourth quarter of 2019.

• SemLogistics provides refined product and crude oil storage services in the U.K. and owns a facility in Wales that has multi-product storage capacity of approximately 8.7 million barrels. We have hired a financial advisor to assist in the evaluation of a potential sale of SemLogistics.

2

• SemMexico purchases, produces, stores, and distributes liquid asphalt cement products in Mexico and operates an in-country network of 12 asphalt cement terminals and modification facilities with a combined storage capacity of approximately 427,000 barrels and two marine terminals with a third under construction. On January 5, 2018, we entered into an agreement to sell SemMexico.

Additionally, we hold an 11.78% ownership interest in the general partner of NGL Energy Partners LP (NYSE: NGL).

Recent Developments

Acquisition of Houston Fuel Oil Terminal Company

On July 17, 2017, we completed the HFOTCO Acquisition. HFOTCO is one of the largest oil terminals in the U.S. and owns a 16.8 million barrel terminal strategically located on the U.S. Gulf Coast with crude pipeline delivery connectivity to the local refining complex, deep water marine access and inbound crude receipt pipeline connectivity, as well as rail/truck loading and unloading capabilities. The terminal, located on 330 acres on the Houston Ship Channel, stores, blends and transports residual fuel and crude oil as well as asphalt via pipeline, barge, rail, truck and ship for major oil companies, refiners, international trading firms and others. HFOTCO is currently executing on contractually supported growth projects, including a new ship dock, a new pipeline and connections, as well as an additional 1.45 million barrels of crude oil storage, expected to be in service mid-2018.

This acquisition:

• Provides us with a premier position on the Houston Ship Channel with strong connectivity to the local refinery complex and inbound receipt capabilities from all major producing basins;

• Significantly enhances our scale and diversifies our business with refinery facing take-or-pay cash flows;

• Uniquely positions us to capitalize on shifting global market trends, including the ability to export products;

• Enables us to capture low-risk growth opportunities; and

• Provides stable cash flows that help support targeted dividend growth.

Consideration for the HFOTCO Acquisition was separated into a payment at closing (the “First Payment”) and a second payment to be made on or before December 31, 2018. The First Payment consisted of approximately $400 million in the form of our shares of Class A common stock issued at a predetermined price of $32.30 per share for a total of 12,383,900 shares, $297 million in cash (which is net of an estimated $4.2 million preliminary adjustment for working capital, net indebtedness and capital expenditures), and approximately $766 million in the form of assumed net indebtedness of HFOTCO. We funded the cash portion of the payment at closing and certain other transaction costs with borrowings under the SemGroup Credit Agreement (as defined herein). The second payment consists of $600 million of cash if paid on December 31, 2018, which amount is discounted at a rate of 5% per annum if paid prior to December 31, 2018, and increases to $680 million if not paid by December 31, 2018, but which amount must be paid any time after December 31, 2018 upon the written request of Buffalo Investor I, L.P. and Buffalo Investor II, L.P. (collectively, the “Sellers”) and, in any event, not later than December 31, 2019 (the “Second Payment”). Neither the Company nor any of its subsidiaries other than Beachhead I LLC and Beachhead II LLC (collectively, the “Buyers”), Buffalo Parent and Beachhead Holdings LLC, the parent company of the Buyers (“Beachhead Holdings” and, together with the Buyers and Buffalo Parent, the “HFOTCO Entities”), will have any obligation to pay the Second Payment to Sellers. Instead, the Second Payment is secured by a guarantee by the HFOTCO Entities and a pledge of the equity interests in Buffalo Parent and the Buyers in favor of the Sellers.

3

We have hired a financial advisor to assist us in the evaluation of the options available to us in making the Second Payment. Preferred options under consideration include the divestiture of non-strategic operating assets in order to focus our capital investments in assets and operations that are central to our overall business strategy, the divestiture of interests in some of our operating assets through partnerships and/or joint ventures or the issuance of structured equity. From time to time we engage in active discussions for the divestiture of such assets or interests. These discussions can involve significant amounts of assets or interests and may reach advanced stages. At the present time, we are continuing to review several situations which, over time, could develop into divestiture opportunities. To date, with the exception of the transactions described under the captions “Sale of Interest in Glass Mountain Pipeline” and “Sale of SemMexico” below, no definitive agreements for the sale of any such assets or interests have been reached. We expect to continue to evaluate and in some cases pursue such opportunities as they may arise.

To provide the Sellers with incremental certainty as to the value of such pledged interests, we have agreed that the HFOTCO Entities will not engage in any business, operations or activity except the holding of equity interests in their subsidiaries until the Second Payment is paid in full. In addition, we have agreed to certain restrictions on the operations of HFOTCO, including restrictions on the incurrence of any liens on its assets or any new debt or liability, as well as limitations on transactions between us and our other subsidiaries, on the one hand, and the HFOTCO Entities and their subsidiaries, including HFOTCO, on the other hand, until the Second Payment is paid in full. The HFOTCO Entities and each of their subsidiaries are unrestricted subsidiaries for all purposes under the indenture governing the Notes and do not guarantee the Old Notes and will not guarantee the New Notes.

Sale of Interest in Glass Mountain Pipeline

On November 8, 2017, we entered into an agreement to sell our 50% interest in Glass Mountain Pipeline, LLC, which owns a 215-mile crude oil pipeline in western and north central Oklahoma and 1.5 million barrels of associated storage, that we operate, to an affiliate of BlackRock Inc.’s Global Energy and Power Infrastructure Fund in partnership with Navigator Energy Services for $300 million in cash. This transaction is part of our previously announced plan to fund the Second Payment discussed above under the caption “Acquisition of Houston Fuel Oil Terminal Company.” We completed this sale transaction on December 22, 2017.

Sale of SemMexico

On January 5, 2018, two of our wholly-owned subsidiaries, SemMaterials, L.P., an Oklahoma limited partnership, and SemMexico, L.L.C., an Oklahoma limited liability company, entered into a Membership Interest Purchase Agreement (the “MIPA”) with Ergon Asfaltos Mexico HC, LLC, a Mississippi limited liability company (“EAMHC”), Ergon Mexico HC, LLC, a Mississippi limited liability company (“EMHC”), and Ergon Asphalt & Emulsions, Inc., a Mississippi corporation, pursuant to which, among other things, SemMaterials, L.P. and SemMexico, L.L.C. (each, a “SemMexico Seller” and, collectively, the “SemMexico Sellers”) agreed to sell their interest in all of the issued and outstanding membership interests (partes sociales) of SemMexico Materials HC, S. de R.L. de C.V., a Mexican limited liability company (“SMHC”), SemMaterials HC México, S. de R.L. de C.V., a Mexican limited liability company (“SHCM”), SemMaterials México, S. de R.L. de C.V., a Mexican limited liability company (“SM”), and SemMaterials SC México, S. de R.L. de C.V., a Mexican limited liability company (“SSCM” and, together with SMHC, SHCM and SM, “SemMexico”), to EAMHC and EMHC.

Pursuant to the MIPA, the SemMexico Sellers have agreed to sell (i) 99.99% and 0.01% of the issued and outstanding membership interests (partes sociales) of SMHC owned by SemMaterials, L.P. and SemMexico, L.L.C., respectively, and (ii) 0.01% of the issued and outstanding membership interests of each of SHCM, SM and SSCM owned by SemMexico, L.L.C. (collectively, the “SemMexico Disposition”), in exchange for

4

$55.0 million U.S. dollars plus or minus the value of non-cash working capital as of closing plus the amount of certain permitted capital expenditures incurred between the execution of the MIPA and closing.

The SemMexico Disposition is expected to close early in the second quarter of 2018, subject to the receipt of certain governmental approvals and the satisfaction of other customary closing conditions.

Sale of Senior Unsecured Notes due 2026

On September 15, 2017, we entered into a purchase agreement with certain of our wholly-owned subsidiaries, as guarantors (the “Guarantors”), and Credit Suisse Securities (USA) LLC, as representative of the several initial purchasers named therein (collectively, the “Initial Purchasers”), pursuant to which, on September 20, 2017, we issued and sold to the Initial Purchasers (the “Offering”) $300 million in aggregate principal amount of the Company’s 7.25% senior unsecured notes due 2026 (the “2026 Notes”), for resale to qualified institutional buyers pursuant to Rule 144A under the Securities Act, and to non-U.S. persons outside the United States pursuant to Regulation S of the Securities Act.

The 2026 Notes were issued under an indenture (the “2026 Notes Indenture”) entered into on September 20, 2017 by and among the Company, the Guarantors and Wilmington Trust, National Association, as trustee. The 2026 Notes are fully and unconditionally guaranteed on a senior unsecured basis by our existing subsidiaries that guarantee the SemGroup Credit Agreement. Interest on the 2026 Notes accrues at a rate of 7.25% per annum and is payable in cash semi-annually on March 15 and September 15 of each year, commencing on March 15, 2018. The 2026 Notes will mature on March 15, 2026.

Prior to March 15, 2021, we may redeem the 2026 Notes, in whole or in part, at any time at a price equal to 100% of the principal amount of the 2026 Notes redeemed plus accrued and unpaid interest to, but not including, the redemption date and a “make-whole premium.” Additionally, from time to time before September 15, 2020, we may choose to redeem up to 35% of the original principal amount of the 2026 Notes at a redemption price equal to 107.250% of the face amount thereof plus accrued and unpaid interest to, but not including, the redemption date, with the net cash proceeds that we raise in one or more equity offerings. On or after March 15, 2021, we may redeem the 2026 Notes, in whole or in part, at the following redemption prices (expressed as a percentage of principal amount), plus accrued and unpaid interest thereon to, but not including, the redemption date if redeemed during the twelve-month period beginning on March 15 of the years indicated below:

Year	Percentage
2021		103.625	%
2022		101.813	%
2023 and thereafter		100.000	%

Upon the occurrence of a change of control triggering event, as defined in the 2026 Notes Indenture, each holder of the 2026 Notes will have the right to require us to repurchase some or all of such holder’s 2026 Notes at 101% of the principal amount thereof, plus accrued and unpaid interest to, but not including, the repurchase date.

The 2026 Notes Indenture contains customary covenants restricting our ability and the ability of our restricted subsidiaries to: (i) incur additional indebtedness or issue certain preferred shares; (ii) pay dividends and make certain distributions, investments and other restricted payments; (iii) create certain liens; (iv) sell assets; (v) enter into transactions with affiliates; (vi) enter into sale and lease-back transactions; (vii) merge, consolidate, sell or otherwise dispose of all or substantially all of our assets; and (viii) designate our subsidiaries as unrestricted subsidiaries under the Indenture. These covenants are subject to a number of important limitations and exceptions, including certain provisions permitting us, subject to the satisfaction of certain conditions, to

5

transfer assets to certain of our unrestricted subsidiaries. Moreover, if the 2026 Notes receive an investment grade rating from Standard and Poor’s or Moody’s Investors Service and no default has occurred and is continuing under the 2026 Notes Indenture, many of the covenants in the 2026 Notes Indenture will be terminated. The 2026 Notes Indenture also contains customary events of default. Upon an event of default under the 2026 Notes Indenture, the trustee or the holders of at least 25% in aggregate principal amount of the 2026 Notes then outstanding may declare all amounts owing under the 2026 Notes to be due and payable.

The Exchange Offer

On March 15, 2017, we completed a private offering of the Old Notes. In connection with the closing of the offering of the Old Notes, we entered into a registration rights agreement with the initial purchasers in the private offering in which we agreed, among other things, to deliver to you this prospectus and to use commercially reasonable efforts to complete the exchange offer within 365 days after the date we issued the Old Notes.

The following summary contains basic information about the exchange offer and is not intended to be complete. It does not contain all information that may be important to you. For a more complete understanding of the exchange offer, please refer to the section entitled “Exchange Offer” in this prospectus.

Exchange Offer We are offering to exchange New Notes for Old Notes.

Expiration Date The exchange offer will expire at 5:00 p.m., New York City time, on                 , 2018, unless we decide to extend it.

Condition to the Exchange Offer The registration rights agreement does not require us to accept Old Notes for exchange if the exchange offer, or the making of any exchange by a holder of the Old Notes, would violate any applicable law or SEC policy. The exchange offer is not conditioned on a minimum aggregate principal amount of Old Notes being tendered.

Procedures for Tendering Old Notes  To participate in the exchange offer, you must follow the procedures established by The Depository Trust Company, which we call “DTC,” for tendering Old Notes held in book-entry form. These procedures, which we call “ATOP,” require that (i) the exchange agent receive, before the expiration date of the exchange offer, a computer generated message known as an “agent’s message” that is transmitted through DTC’s automated tender offer program and (ii) DTC has received:

• your instructions to exchange your Old Notes; and

• your agreement to be bound by the terms of the letter of transmittal.

For more information on tendering your Old Notes, please refer to the sections in this prospectus entitled “Exchange Offer—Terms of the Exchange Offer,” “—Procedures for Tendering,” and “Book-Entry; Delivery and Form.”

Guaranteed Delivery Procedures None.

Withdrawal of Tenders You may withdraw your tender of Old Notes at any time before the expiration date. To withdraw, you must submit a notice of withdrawal to the exchange agent using ATOP procedures before 5:00 p.m., New York City time, on the expiration date of the exchange offer. Please refer to the section in this prospectus entitled “Exchange Offer—Withdrawal of Tenders.”

Acceptance of Old Notes and Delivery of New Notes If you fulfill all conditions required for proper acceptance of Old Notes, we will accept any and all Old Notes that you properly tender

7

in the exchange offer on or before 5:00 p.m., New York City time, on the expiration date. We will return any Old Notes that we do not accept for exchange to you without expense promptly after the expiration date and acceptance of the Old Notes for exchange. Please refer to the section in this prospectus entitled “Exchange Offer—Terms of the Exchange Offer.”

Fees and Expenses We will bear expenses related to the exchange offer. Please refer to the section in this prospectus entitled “Exchange Offer—Fees and Expenses.”

Use of Proceeds The issuance of the New Notes will not provide us with any new proceeds. We are making this exchange offer solely to satisfy our obligations under our registration rights agreement.

Consequences of Failure to Exchange Old Notes If you do not exchange your Old Notes in this exchange offer, you will no longer be able to require us to register the Old Notes under the Securities Act except in limited circumstances provided under the registration rights agreement. In addition, you will not be able to resell, offer to resell or otherwise transfer the Old Notes unless we have registered the Old Notes under the Securities Act, or unless you resell, offer to resell or otherwise transfer them under an exemption from the registration requirements of, or in a transaction not subject to, the Securities Act.

In addition, after the consummation of the exchange offer, it is anticipated that the outstanding principal amount of the Old Notes available for trading will be significantly reduced. The reduced float may adversely affect the liquidity and market price of the Old Notes. A smaller outstanding principal amount of Old Notes available for trading may also make the price of the Old Notes more volatile.

U.S. Federal Income Tax Consequences The exchange of New Notes for Old Notes in the exchange offer will not be a taxable event for U.S. federal income tax purposes. Please read “Material United States Federal Tax Consequences.”

Exchange Agent We have appointed Wilmington Trust, National Association, as exchange agent for the exchange offer. You should direct questions and requests for assistance, requests for additional copies of this prospectus or the letter of transmittal to the exchange agent addressed as follows: Wilmington Trust, National Association, c/o Wilmington Trust Company, Corporate Capital Markets, Rodney Square North, 1100 N. Market Street, Wilmington, DE 19890-1626. Eligible institutions may make requests by facsimile at (302) 636-4139 and may confirm facsimile delivery by calling (302) 636-6181.

Limited Public Market for the Notes  The New Notes generally will be freely transferrable but will also be securities for which the public market may be limited. We do not

10

intend to apply for a listing of the New Notes on any securities exchange or any automated dealer quotation system. Accordingly, we cannot assure you as to the development, persistence or liquidity of a market for the New Notes.

Risk Factors The New Notes involve risks. See “Risk Factors” beginning on page 16 for a discussion of certain factors you should consider in evaluating an investment in the New Notes.

SUMMARY HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

The following table provides summary historical and pro forma consolidated financial data as of and for the periods shown. The historical balance sheet data as of December 31, 2012, 2013, 2014, 2015 and 2016 and the historical statement of operations data for the years ended December 31, 2012, 2013, 2014, 2015 and 2016 have been derived from our audited financial statements for those dates and periods. The historical balance sheet data as of September 30, 2016 and 2017 and the historical statement of operations data for the nine months ended September 30, 2016 and 2017 have been derived from our unaudited financial statements for those dates and periods. Our summary historical results are not necessarily indicative of results to be expected in future periods.

The unaudited pro forma financial data presented below for the year ended December 31, 2016, for the nine months ended September 30, 2017 and as of September 30, 2017 have been derived from, and should be read together with, our unaudited pro forma consolidated financial statements, including the related notes, for those dates and periods. The pro forma statement of operations data give pro forma effect to the HFOTCO Acquisition and the SemMexico Disposition as if the transactions had occurred on January 1, 2016. The pro forma balance sheet data give pro forma effect to the SemMexico Disposition as if the transaction had occurred on September 30, 2017. The pro forma financial data does not purport to reflect the results of operations that would have occurred if the closing of the HFOTCO Acquisition and the SemMexico Disposition had actually occurred on January 1, 2016 or September 30, 2017, as the case may be. We have based the adjustments necessary to fairly present the unaudited pro forma financial data on available information and believe the adjustments are reasonable. We provide the summary pro forma financial data for illustrative purposes only, and you should not view them as a projection or forecast of our performance for any future period.

The summary financial data presented below are qualified in their entirety by reference to, and should be read in conjunction with, “Selected Consolidated Financial Data,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements, including the related notes, in our Annual Report on Form 10-K for the year ended December 31, 2016 and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2017 and the unaudited pro forma consolidated financial statements, including the related notes, in our Current Report on Form 8-K/A filed on August 31, 2017 and our Current Report on Form 8-K filed on January 8, 2018, each of which is incorporated by reference in this prospectus.

We have experienced many changes in our business during the periods shown in the table below, which significantly limits the comparability of the historical financial data. Such changes include, but are not limited to, various impairments of long-lived assets and gains/losses on disposal of long-lived assets.

(1) Covenant EBITDA is only being provided on a pro forma basis for the year ended December 31, 2016 and for the nine months ended September 30, 2017. For information regarding our definitions of Adjusted EBITDA and Covenant EBITDA, our reasons for using Adjusted EBITDA and Covenant EBITDA as supplemental financial measures and a reconciliation of each of these measures to its most directly comparable GAAP financial measure, please see “—Non-GAAP Financial Measures and Reconciliations” in this prospectus and for additional information regarding Adjusted EBITDA please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—How We Evaluate Our Operations” in our Annual Report on Form 10-K for the year ended December 31, 2016.

(2) For the definitions of “earnings” and “fixed charges” for purposes of this computation, please see “Ratio of Earnings to Fixed Charges.”

(3) Earnings for the nine months ended September 30, 2017, were insufficient to cover fixed charges by $47.4 million.

Non-GAAP Financial Measures and Reconciliations

Adjusted EBITDA and Covenant EBITDA are not financial measures presented in accordance with GAAP. We believe that the presentation of these non-GAAP financial measures will provide useful information to investors in assessing our financial condition and results of operations.

We define Adjusted EBITDA as net income (loss) before interest expense, income tax expense (benefit), depreciation and amortization and adjusted for selected items that we believe impact the comparability of financial results between reporting periods. In addition to non-cash items, we have selected items for adjustment to EBITDA which management feels decrease the comparability of our results among periods. These items are identified as those which are generally outside of the results of day to day operations of the business. These items are not considered non-recurring, infrequent or unusual, but do erode comparability among periods in which they occur with periods in which they do not occur or occur to a greater or lesser degree. Historically, we have selected items such as gains on the sale of common units of NGL Energy Partners LP, costs related to our predecessor’s bankruptcy, significant business development related costs, significant legal settlements, severance and other similar costs. Management believes these types of items can make comparability of the results of day to day operations among periods difficult and have chosen to remove these items from our Adjusted EBITDA. We expect to adjust for similar types of items in the future. Although we present selected items that we consider in evaluating our performance, you should be aware that the items presented do not represent all items that affect comparability between the periods presented. Variations in our operating results are also caused by changes in volumes, prices, mechanical interruptions and numerous other factors. We do not adjust for these types of variances. We use Adjusted EBITDA as a supplemental performance measure to assess:

• our operating performance as compared to that of other companies in our industry, without regard to financing methods, historical cost basis, capital structure or the impact of fluctuating commodity prices; and

• the viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

Covenant EBITDA is determined by reference to the related definitions in the SemGroup Credit Agreement and the Indenture and is calculated as net income (loss) before interest expense, income tax expense (benefit), depreciation and amortization and adjusted for other selected items set forth in the SemGroup Credit Agreement and the Indenture. Covenant EBITDA is used to determine our compliance with certain covenants in the SemGroup Credit Agreement and the Indenture.

Net income (loss) is the GAAP financial measure most directly comparable to each of Adjusted EBITDA and Covenant EBITDA. Our non-GAAP financial measures should not be considered as alternatives to the most directly comparable GAAP financial measures. Each of these non-GAAP financial measures has important limitations as an analytical tool because it excludes some, but not all, items that affect the most directly comparable GAAP financial measure. You should not consider Adjusted EBITDA or Covenant EBITDA in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA and

13

Covenant EBITDA may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to a similarly titled measure of other companies, thereby diminishing their utility.

Management compensates for the limitations of Adjusted EBITDA and Covenant EBITDA as analytical tools by reviewing the comparable GAAP financial measures, understanding the difference between Adjusted EBITDA and Covenant EBITDA, on the one hand, and each of their respective most directly comparable GAAP financial measures, on the other hand, and incorporating this knowledge into its decision-making processes. We believe that investors benefit from having access to the same financial measures that our management uses in evaluating our operating results.

The following table presents a reconciliation of net income (loss), the most directly comparable GAAP financial measure, to each of Adjusted EBITDA and Covenant EBITDA on a historical basis and on a pro forma basis, as the case may be, for the periods indicated.

RISK FACTORS

You should carefully consider the information included or incorporated by reference in this prospectus, including the matters addressed under “Cautionary Note Regarding Forward-Looking Statements” and the risks described below. In addition, you should read the risk factors and cautionary statements which are incorporated by reference in this prospectus, including those described under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2016 and, to the extent applicable, in any subsequently filed reports.

We are subject to certain risks and hazards due to the nature of the business activities we conduct. The risks discussed below, any of which could materially and adversely affect our business, financial condition, cash flows and results of operations, are not the only risks we face. We may experience additional risks and uncertainties not currently known to us; or, as a result of developments occurring in the future, conditions that we currently deem to be immaterial may also materially and adversely affect our business, financial condition, cash flows and results of operations.

Risks Related to Our Indebtedness and the Notes

If you do not properly tender your Old Notes, you will continue to hold unregistered Old Notes and your ability to transfer Old Notes will remain restricted and may be adversely affected.

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 carefully follow the instructions on how to tender your Old Notes. Neither we nor the exchange agent is required to tell you of any defects or irregularities with respect to your tender of Old Notes.

If you do not exchange your Old Notes for New Notes under the exchange offer, your Old Notes will continue to be subject to the existing transfer restrictions. 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. We do not plan to register Old Notes under the Securities Act unless our registration rights agreement with the initial purchasers of the Old Notes requires us to do so. Further, if you continue to hold any Old Notes after the exchange offer is consummated, you may have trouble selling them because there will be fewer of the Old Notes outstanding.

Our indebtedness could limit our flexibility, adversely affect our financial health and prevent us from making payments on the Notes.

As of September 30, 2017, we had $3,015.0 million of indebtedness outstanding, net of premiums, discounts and other deferred financing costs (which includes the Old Notes, $400 million outstanding under our 5.625% senior notes due 2022 (the “2022 Notes”), $350 million outstanding under our 5.625% senior notes due 2023 (the “2023 Notes”), $300 million outstanding under the 2026 Notes, $332 million outstanding under our amended and restated credit agreement with Wells Fargo Bank, National Association, as administrative agent and collateral agent, the various arrangers, bookrunners and agents party thereto, certain of our subsidiaries and the lenders party thereto (as amended, the “SemGroup Credit Agreement”), $225 million outstanding of limited obligation revenue bonds due November 1, 2050 (the “HFOTCO IKE Bonds”), $558.5 million outstanding under the credit agreement, which was amended in connection with the closing of the HFOTCO Acquisition, among BGCT, as the parent, HFOTCO, as the borrower, Morgan Stanley Senior Funding, Inc., as administrative agent, Bank of America, N.A., as collateral agent, and the lenders party thereto (as amended, the “HFOTCO Credit Agreement”), and $600 million due as the Second Payment for the HFOTCO Acquisition), and the right to borrow up to an additional $682.4 million under our credit facilities (which includes $628.6 million (net of $39.4 million of outstanding letters of credit), $3.8 million and $50.0 million of availability under the SemGroup Credit Agreement, the SemMexico credit facility and the HFOTCO Credit Agreement, respectively). The HFOTCO

16

Entities and their subsidiaries have various obligations as to the HFOTCO Credit Agreement, the HFOTCO IKE Bonds and the Second Payment and are not providing cross-guarantees for any of our other indebtedness. The HFOTCO Entities and their subsidiaries are unrestricted subsidiaries for all purposes under the Indenture. We also have a bilateral letter of credit facility that allows us to issue up to $100 million of secured bilateral letters of credit. As of September 30, 2017, we had $51.1 million of outstanding bilateral letters of credit and $48.9 million of additional capacity under this facility.

Our level of indebtedness could have important consequences to you. For example, it could:

• make it difficult for us to satisfy our obligations with respect to the Notes;

• make us more vulnerable to general adverse economic and industry conditions;

• require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow for operations and other purposes;

• limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and

• place us at a competitive disadvantage compared to competitors that may have proportionately less indebtedness.

In addition, our ability to make scheduled payments or to refinance our obligations depends on our successful financial and operating performance. We cannot assure you that our operating performance will generate sufficient cash flow or that our capital resources will be sufficient for payment of our debt obligations in the future. Our financial and operating performance, cash flow, and capital resources depend on prevailing economic conditions and financial, business and other factors, many of which are beyond our control.

If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to sell material assets or operations, obtain additional capital or restructure our debt. In the event that we are required to dispose of material assets or operations or restructure our debt to meet our debt service and other obligations, we cannot assure you as to the terms of any such transaction or how quickly any such transaction could be completed, if at all.

Despite our current leverage and the restrictions contained in our existing debt instruments, we may still be able to incur substantially more debt. This could further exacerbate the risks that we and our subsidiaries face.

Despite our current leverage and the restrictions contained in our existing debt instruments, including our credit facilities and the Indenture, we may be able to incur substantial additional indebtedness in the future. If new debt is added to our current debt levels, the related risks that we now face could increase. Our level of indebtedness could, for instance, prevent us from engaging in transactions that might otherwise be beneficial to us or from making desirable capital expenditures. This could put us at a competitive disadvantage relative to other less leveraged competitors that have more cash flow to devote to their operations. In addition, the incurrence of additional indebtedness could make it more difficult to satisfy our existing financial obligations, including those relating to the Notes.

The instruments governing our indebtedness contain various covenants limiting the conduct of our business.

The Indenture, the SemGroup Credit Agreement, the HFOTCO Credit Agreement, the indentures governing the 2022 Notes, the 2023 Notes, the 2026 Notes and the HFOTCO IKE Bonds, the Continuing Covenant Agreement dated as of August 19, 2014, among BGCT, as the parent, HFOTCO, as obligor, Bank of America, N.A., as administrative agent and collateral agent, and the bondholders party thereto, which was amended in

17

connection with the closing of the HFOTCO Acquisition (as amended, the “Continuing Covenant Agreement”), and the instruments governing our other indebtedness contain, various restrictive covenants that limit the conduct of our business. The SemGroup Credit Agreement, the HFOTCO Credit Agreement and the Continuing Covenant Agreement also require us to maintain certain financial ratios. These covenants and restrictions limit our ability to respond to changing business and economic conditions and may prevent us from engaging in transactions that might otherwise be considered beneficial to us. In particular, these agreements place certain limits on our ability to, among other things:

• incur additional indebtedness;

• incur liens;

• enter into sale and lease back transactions;

• make investments;

• pay dividends or distributions;

• make certain restricted payments;

• consummate certain asset sales;

• enter into certain transactions with affiliates; and

• merge, consolidate and/or sell or dispose of all, or substantially all, of our assets.

You should read the discussion under the heading “Description of the Notes—Certain Covenants” for further information about the covenants under the Indenture.

If we fail to comply with the restrictions in the Indenture, the SemGroup Credit Agreement, the HFOTCO Credit Agreement, the indentures governing the 2022 Notes, the 2023 Notes, the 2026 Notes and the HFOTCO IKE Bonds, the Continuing Covenant Agreement and the instruments governing our other indebtedness or any other subsequent financing agreements, a default may allow the creditors, if the agreements so provide, to accelerate the related indebtedness as well as any other indebtedness to which a cross-acceleration or cross-default provision applies. If that occurs, we may not be able to make all of the required payments or borrow sufficient funds to refinance such debt. Even if new financing were available at that time, it may not be available on terms acceptable to us.

If we are unable to repay amounts outstanding under the SemGroup Credit Agreement, the HFOTCO Credit Agreement or the HFOTCO IKE Bonds when due, the lenders or trustee thereunder, as the case may be, could, subject to the terms of such credit agreements or bonds, seek to sell or otherwise transfer our assets granted to them as collateral to secure the indebtedness outstanding under such credit agreements or bonds. Substantially all of the assets of SemGroup Corporation and the subsidiary guarantors have been pledged as collateral to secure the SemGroup Credit Agreement. Substantially all of the assets of HFOTCO have been pledged as collateral to secure the HFOTCO Credit Agreement and the HFOTCO IKE Bonds. In addition, the lenders under the SemGroup Credit Agreement and the HFOTCO Credit Agreement could choose to terminate any commitment to supply us with further funds.

Our failure to make the Second Payment or comply with the terms of the Guarantee, Pledge, and Security Agreement with the Sellers (the “HFOTCO Pledge Agreement”) could have material adverse consequences to us. In addition, the terms of the HFOTCO Pledge Agreement limit the conduct of HFOTCO business.

The total purchase consideration to acquire HFOTCO consists of two payments. On July 17, 2017, upon the closing of the HFOTCO Acquisition, we made the First Payment to the Sellers. The Second Payment requires us to pay the Sellers $600 million in cash if paid on December 31, 2018. If paid prior to December 31, 2018, the amount payable will be discounted by 5% per annum. If not paid by December 31, 2018, the amount payable

18

increases to $680 million and is due by December 31, 2019 or earlier if requested by the Sellers. The Second Payment is secured by the HFOTCO Pledge Agreement pursuant to which the HFOTCO Entities guaranteed the obligation to pay the Second Payment and the Second Payment is secured by a pledge of the equity interests of Buffalo Parent and the Buyers.

The HFOTCO Pledge Agreement contains certain customary affirmative and negative covenants, which, among other things and subject to the exceptions and materiality qualifiers set forth therein, generally (i) require the HFOTCO Entities to maintain their existence, provide or make available to Sellers certain financial and other information regarding the HFOTCO Entities and their subsidiaries, and operate in compliance with applicable legal requirements and permits, and (ii) restrict the ability of the HFOTCO Entities to incur liens on any of their respective assets other than permitted liens, make certain restricted payments, sell any assets, form new subsidiaries, liquidate, wind-up or dissolve, merge or sell all or substantially all of their respective assets, establish trade names, make certain investments, engage in certain transactions with affiliates and amend or waive rights under the organizational documents or the HFOTCO Credit Agreement, in each case until such time as the Second Payment is paid in full. The HFOTCO Pledge Agreement contains customary events of default, including certain representations and warranties set forth in such agreement or related to the enforceability of the obligation to pay the Second Payment being proved to be false, the failure of the Buyers to pay the Second Payment when due, the breach of specified covenants (in some cases, following a specified cure period), an event of default under the HFOTCO Credit Agreement or debt agreements other than certain events of default waived by the applicable lenders party thereto, the initiation of involuntary or voluntary bankruptcy proceedings by or against us or certain of our subsidiaries, the failure to discharge certain judgments within 60 days after entry thereof, and a change of control (as defined in the HFOTCO Pledge Agreement). Upon the occurrence of an event of default, the Sellers have the right to, among other things, force the sale of the pledged equity interests in the Buyers and Buffalo Parent to satisfy the Second Payment.

The Notes are unsecured.

The Notes are not secured by any of our or our subsidiaries’ assets. The Indenture permits us and our subsidiaries to incur secured debt. As a result, the Notes and the guarantees thereof are effectively subordinated to all of our and the guarantors’ secured obligations to the extent of the value of the assets securing such obligations. As of September 30, 2017, we had no secured debt outstanding other than the $332 million, the $558.5 million and the $225 million outstanding under the SemGroup Credit Agreement, the HFOTCO Credit Agreement and the HFOTCO IKE Bonds, respectively, and we had $628.6 million and $50.0 million of availability under the secured revolving credit facilities under the SemGroup Credit Agreement and the HFOTCO Credit Agreement, respectively. If we or the subsidiary guarantors were to become insolvent or otherwise fail to make payment on the Notes or the guarantees, holders of any of our and the subsidiary guarantors’ secured obligations would be paid first and would receive payments from the assets securing such obligations before the holders of the Notes would receive any payments. Holders of Notes may therefore not be fully repaid if we or the subsidiary guarantors become insolvent or otherwise fail to make payment on the Notes.

Many of our subsidiaries are not guarantors, and therefore the Notes are structurally subordinated in right of payment to the indebtedness and other liabilities of our existing and future subsidiaries that do not guarantee the Notes. Your right to receive payments on the Notes could be adversely affected if any of these non-guarantor subsidiaries declare bankruptcy, liquidate or reorganize.

The Notes are not guaranteed by any of our unrestricted subsidiaries, including our foreign subsidiaries and the HFOTCO Entities and their subsidiaries. On a pro forma basis after giving effect to the HFOTCO Acquisition and the SemMexico Disposition, our subsidiaries that do not guarantee the Notes accounted for approximately 19.7% of our total revenue for the nine months ended September 30, 2017. In addition, as of September 30, 2017, our non-guarantor subsidiaries comprised approximately 59.5% of our total assets and approximately 42.2% of our total liabilities. Accordingly, claims of holders of the Notes are structurally subordinate to the claims of creditors of these non-guarantor subsidiaries, including trade creditors. All obligations of our non-guarantor

19

subsidiaries will have to be satisfied before any of the assets of such subsidiaries would be available for distribution, upon a liquidation or otherwise, to us or a guarantor of the Notes.

The HFOTCO Entities and each of their subsidiaries do not provide any credit support for the Notes and are unrestricted subsidiaries. Additionally, the distribution of cash flows generated by the HFOTCO Entities and their subsidiaries to us is restricted by existing indebtedness of the HFOTCO Entities.

The HFOTCO Entities and each of their subsidiaries do not provide any credit support for the Notes or any other of our indebtedness other than obligations they may have with respect to the HFOTCO Credit Agreement, the HFOTCO IKE Bonds and the Second Payment and will have no obligation, contingent or otherwise, to pay amounts due under the Notes or to make any funds available to pay those amounts, whether by dividend, distribution, loan, direct payment or other payment. The Notes are therefore structurally subordinated to all liabilities of the HFOTCO Entities and their subsidiaries, and claims of holders of the Notes are structurally subordinated to the claims of creditors of the HFOTCO Entities and their subsidiaries, including trade creditors. All such obligations would have to be satisfied before any of the assets of the HFOTCO Entities or any of their subsidiaries would be available for distribution, upon liquidation or otherwise, to us or a guarantor of the Notes.

Subject to the terms of the Indenture, we are permitted to create unrestricted subsidiaries, which will not be subject to any of the covenants in the Indenture. Any such subsidiaries will be able to engage in many of the activities that we and our restricted subsidiaries are prohibited or limited from doing under the terms of the Indenture, such as selling, conveying or distributing assets, incurring additional debt, pledging assets, guaranteeing debt, paying dividends, making investments and entering into mergers or other business combinations, subject to certain restrictive covenants in their existing credit facilities and financing documents, as applicable. Unrestricted subsidiaries may also enter into financing arrangements that limit their ability to make loans or other payments to fund payments in respect of the Notes. Accordingly, we may not be able to rely on the cash flow or assets of unrestricted subsidiaries to pay any of our indebtedness, including the Notes. In addition, the terms of certain of the existing HFOTCO indebtedness, contain covenants that restrict its ability to pay dividends and make other distributions to SemGroup. As a result, cash flows generated by the HFOTCO Entities and their subsidiaries will be limited as necessary to satisfy these covenants and therefore may not be available to make principal or interest payments on the Notes.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under the SemGroup Credit Agreement, the HFOTCO Credit Agreement and the HFOTCO IKE Bonds bear interest at variable rates and expose us to interest rate risk. If interest rates increase and we are unable to effectively hedge our interest rate risk, our debt service obligations on the variable rate indebtedness would increase even if the amount borrowed remained the same, and our cash available for servicing our indebtedness would decrease. As of September 30, 2017, a 1.0% increase in interest rates on the debt outstanding under the SemGroup Credit Agreement, the HFOTCO Credit Agreement and the HFOTCO IKE Bonds would have cost us approximately $0.8 million, $1.4 million and $0.6 million in additional annual interest expense, respectively.

Any failure to meet our debt obligations could harm our business, financial condition and results of operations.

If our cash flow and capital resources are insufficient to fund our debt obligations, we may be forced to sell assets, seek additional equity or debt capital or restructure our debt. In the event that we are unable to make the Second Payment, the Sellers have a right to the property of the HFOTCO Entities to satisfy the Second Payment and costs for any related sale or liquidation. In addition, any failure to make scheduled payments of interest and principal on our outstanding indebtedness would likely result in a downgrade of our credit rating, which could harm our ability to incur additional indebtedness on acceptable terms to us, if at all. Our cash flow and capital resources may be insufficient for payment of interest on and principal of our debt in the future, including

20

payments on the Notes, and any such alternative measures may be unsuccessful or may not permit us to meet scheduled debt service obligations, which could cause us to default on our obligations and impair our liquidity.

We may be unable to purchase your Notes upon a change of control triggering event.

Upon the occurrence of a change of control triggering event, as defined in the Indenture, we will be required to offer to purchase your Notes. We may not have sufficient financial resources to purchase all of the Notes that holders tender to us pursuant to a change of control triggering event offer, or might be prohibited from doing so under the SemGroup Credit Agreement or our other indebtedness. The occurrence of a change of control triggering event could also constitute an event of default under the SemGroup Credit Agreement or our other indebtedness. See “Description of the Notes—Repurchase at the Option of Holders—Change of Control Triggering Event.”

Holders of the Notes may not be able to determine when a change of control giving rise to their right to have the Notes repurchased has occurred following a sale of “substantially all” of our assets.

The definition of “change of control” in the Indenture 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 Company and its 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 us to repurchase its Notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Company and its subsidiaries taken as a whole to another person or group may be uncertain.

Because substantially all of our operations are conducted through our subsidiaries, our ability to service our debt is largely dependent on our receipt of distributions or other payments from our subsidiaries.

Substantially all of our operations are conducted through our subsidiaries. As a result, our ability to make interest and principal payments on the Notes is largely dependent on the earnings of our subsidiaries and the payment of those earnings to us in the form of dividends, loans or advances and through repayment of loans or advances from us. Unless they are guarantors, our subsidiaries do not have any obligation to pay amounts due on the Notes or to make funds available for that purpose. Payments to us by our subsidiaries will be contingent upon our subsidiaries’ earnings and other business considerations and may be subject to statutory or contractual restrictions. Distributions to us from the HFOTCO Entities are limited under the HFOTCO Credit Agreement and the Continuing Covenant Agreement, and, in accordance with the Pledge Agreement, such limitations may not be modified until the Second Payment is paid in full. In addition, there may be significant tax and other legal restrictions on the ability of our non-U.S. subsidiaries to remit money to us.

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

Creditors of any business are protected by fraudulent conveyance or fraudulent transfer laws that differ among various jurisdictions and these laws may apply to the issuance of the Notes or the guarantees by the subsidiary guarantors. The Notes or the guarantees may be voided by a court, or subordinated to the claims of other creditors, if, among other things:

• the indebtedness evidenced by the Notes or the guarantees was incurred by us or a subsidiary guarantor with actual intent to hinder, delay or defraud any present or future creditor of ours or such subsidiary guarantor; or

• we or the subsidiary guarantors did not receive fair consideration or reasonably equivalent value for issuing the Notes or the guarantees and we or the applicable subsidiary guarantors:

(1) were insolvent or were rendered insolvent by reason of issuing the Notes or the applicable guarantee,

21

(2) were engaged or about to engage in a business or transaction for which the remaining assets of ours or the applicable subsidiary guarantor constituted unreasonably small capital, or

(3) intended to incur, or believed that we or they would incur, indebtedness beyond our or their ability to pay as they matured.

In addition, any payment by us or such subsidiary guarantor under the Notes or any guarantee could be voided and required to be returned to us or such subsidiary guarantor or to a fund for the benefit of the creditors of ours or such subsidiary guarantor.

The measures of insolvency for purposes of these fraudulent transfer or fraudulent conveyance laws will vary depending on the law applied in any proceeding to determine whether a fraudulent transfer or fraudulent conveyance has occurred, such that we cannot be certain as to: the standards a court would use to determine whether or not we or any subsidiary guarantors were solvent at the relevant time, or, regardless of the standard that a court uses, that it would not determine that we or any subsidiary guarantor was indeed insolvent on that date; that any payments to the holders of the Notes (including under any guarantees) did not constitute preferences, fraudulent transfers or fraudulent conveyances on other grounds; or that the issuance of the Notes and any guarantees would not be avoided or subordinated to our or any subsidiary guarantor’s other debt. Generally, however, we or a subsidiary guarantor would be considered insolvent if:

• the sum of our or such subsidiary guarantor’s debts, including contingent liabilities, were greater than the fair value of all of our or such subsidiary guarantor’s assets;

• the present fair saleable value of our or such subsidiary guarantor’s assets were less than the amount that would be required to pay our or such subsidiary guarantor’s probable liability on existing debts, including contingent liabilities, as they become absolute and mature; or

• we or any subsidiary guarantor could not pay debts as they become due.

As a general matter, value is given for a transfer or an obligation if, in exchange for the transfer or obligation, property is transferred or a valid antecedent debt is satisfied. Based on financial and other information, we believe that the Notes and the guarantees will be incurred for proper purposes and in good faith and that we and each subsidiary guarantor are solvent and will continue to be solvent after this offering is completed, will have sufficient capital for carrying on its business after this offering is completed and will be able to pay our or its indebtedness as it matures. We cannot assure you, however, that a court reviewing these matters would agree with us. A legal challenge to the Notes or a guarantee on fraudulent conveyance or fraudulent transfer grounds may focus on the benefits, if any, realized by us or the subsidiary guarantors as a result of the issuance of the guarantees. Specifically, a court would likely find that we or any subsidiary guarantor did not receive reasonably equivalent value or fair consideration for the Notes or any such guarantee if we or such subsidiary guarantor did not substantially benefit directly or indirectly from the issuance of the Notes or the applicable guarantee. Thus, if any such guarantees were legally challenged, it could be subject to the claim that, since the guarantee was incurred for our benefit, and only indirectly for the benefit of the subsidiary guarantor, the obligations of the applicable subsidiary guarantor were incurred for less than reasonably equivalent value or fair consideration. Therefore, a court could void the obligations under the guarantees, subordinate them to the applicable subsidiary guarantor’s other debt, or take other action detrimental to the holders of the Notes.

Additionally, under federal bankruptcy or applicable state insolvency law, if bankruptcy or insolvency proceedings were initiated by or against us or any subsidiary guarantor within 90 days (or one year before commencement of a bankruptcy proceeding if the creditor that benefited from the payment is an “insider” under the United States Bankruptcy Code) after any payment by us or a subsidiary guarantor with respect to the Notes or any guarantee, all or a portion of such payment could be avoided as a preferential transfer, and the recipient of such payment could be required to return it.

22

Finally, as a court of equity, the bankruptcy court may otherwise subordinate the claims in respect of the Notes or any guarantees to other claims against us or any subsidiary guarantors under the principle of equitable subordination, if the court determines that: (i) the holder of the Notes engaged in some type of inequitable conduct; (ii) such inequitable conduct resulted in injury to our or such subsidiary guarantor’s other creditors or conferred an unfair advantage upon the holder of the Notes; and (iii) equitable subordination is not inconsistent with the provisions of the United States Bankruptcy Code.

The Indenture contains a provision intended to limit each subsidiary guarantor’s liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. Such provision may not be effective to protect the subsidiary guarantees from being voided under fraudulent transfer or fraudulent conveyance law; a bankruptcy court decision in Florida (which was reinstated by the applicable federal circuit court of appeals on other grounds) questioned the validity of such customary saving clause in a guarantee.

Receipt of payment on the Notes, as well as the enforcement of remedies under the subsidiary guarantees, may be limited in bankruptcy or in equity.

An investment in the Notes, as in any type of security, involves insolvency and bankruptcy considerations that investors should carefully consider. If we or any of the subsidiary guarantors become a debtor subject to insolvency proceedings under the United States Bankruptcy Code or any other applicable bankruptcy or insolvency law, it is likely to result in delays in the payment of the Notes and in the exercise of enforcement remedies under the Notes or the subsidiary guarantees. Provisions under the United States Bankruptcy Code (or any other applicable bankruptcy or insolvency law) or general principles of equity that could result in the impairment of your rights include the automatic stay, avoidance of preferential or fraudulent transfers by a trustee or a debtor-in-possession, substantive consolidation, limitations of collectability of unmatured interest or attorneys’ fees and forced restructuring of the Notes. Accordingly, we cannot predict whether or when payments on the Notes could be made following the commencement of any bankruptcy proceeding, the length of any delay in making such payments, or what the ultimate recovery to the noteholders would be at the conclusion of such proceedings.

If a bankruptcy court substantively consolidated us and our subsidiaries, the assets of each entity would be subject to the claims of creditors of all entities. This would expose you not only to the usual impairments arising from bankruptcy, but also to potential dilution of the amount ultimately recoverable because of the larger creditor base. Furthermore, a forced restructuring of the Notes could occur through the “cram-down” provision of the United States Bankruptcy Code. Under this provision, the Notes could be restructured over your objections as to their general terms, including interest rate and maturity.

Your ability to transfer the Notes may be limited by the absence of an active trading market, and there is no assurance that any active trading market for the Notes will develop or persist.

The Old Notes have not been registered under the Securities Act, and may not be resold by holders thereof unless the Old Notes are subsequently registered or an exemption from the registration requirements of the Securities Act is available. However, we cannot assure you that, even following registration or exchange of the Old Notes for New Notes, that an active trading market for the Old Notes or the New Notes will exist (or persist, if developed), and we will have no obligation to create such a market. At the time of the private placement of the Old Notes, the initial purchasers advised us that they intended to make a market in the Old Notes and, if issued, the New Notes. The initial purchasers are not obligated, however, to make a market in the Old Notes or the New Notes and any market making may be discontinued at any time at their sole discretion. No assurance can be given as to the liquidity of or trading market for the Old Notes or the New Notes.

The liquidity of any trading market for the Notes and the market price quoted for the Notes will depend on many factors, including among other things:

• changes in the overall market for non-investment grade securities;

23

• changes in our financial performance or prospects;

• the prospects for companies in our industry generally;

• the number of holders of the Notes;

• the interest of securities dealers in making a market for the Notes; and

• prevailing interest rates.

In addition, the market for non-investment grade indebtedness has been historically subject to disruptions that have caused substantial volatility in the prices of securities similar to the Notes. The market for the Notes, if any, may be subject to similar disruptions. Any such disruption could adversely affect the value of your Notes.

A ratings agency downgrade could lead to increased borrowing costs and credit stress.

If one or more rating agencies that rate the Notes either assigns the Notes a rating lower than the rating expected by investors, or reduces its rating in the future, the market price of the Notes, if any, would be adversely affected. In addition, if any of our other outstanding debt that is rated is downgraded, raising capital will become more difficult for us, borrowing costs under the SemGroup Credit Agreement, the HFOTCO Credit Agreement and other future borrowings may increase and the market price of the Notes, if any, may decrease.

Many of the covenants to be contained in the Indenture will terminate if the Notes are rated investment grade by either of Standard & Poor’s or Moody’s Investors Service, Inc. and no default has occurred and is continuing.

Many of the covenants contained in the Indenture will terminate if the Notes are rated investment grade by either Standard & Poor’s or Moody’s,provided that at such time no default has occurred and is continuing. The covenants restrict, among other things, our ability to pay distributions, incur debt and enter into certain other transactions. There can be no assurance that the Notes will ever be rated investment grade. However, termination of these covenants would allow us to engage in certain transactions that would not be permitted while these covenants are in force, and the effects of any such transactions will be permitted to remain in place even if the Notes are subsequently downgraded below investment grade. See “Description of the Notes—Covenant Termination.”

Risks Related to Our Business

The Tax Cuts and Jobs Act could have material effects on the Company.

The Tax Cuts and Jobs Act of 2017 (“Tax Act”), which was signed into law on December 22, 2017, makes significant changes to the taxation of U.S. business entities. These changes include a permanent reduction to the federal corporate income tax rate and changes in the deductibility of interest on corporate debt obligations, among others. Although we are evaluating the Tax Act with our professional advisers, the impact of the Tax Act on our business is currently uncertain.

EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

At the closing of the offering of the Old Notes, we and the guarantors of the Notes entered into a registration rights agreement with the initial purchasers of the Old Notes. In the registration rights agreement, we agreed, for the benefit of the holders of the Old Notes, at our cost, to do the following:

• file an exchange offer registration statement with the SEC with respect to the exchange offer for the New Notes;

• use commercially reasonable efforts to cause the exchange offer registration statement to be declared effective under the Securities Act; and

• offer the New Notes in exchange for surrender of the Old Notes upon the SEC’s declaring the exchange offer registration statement effective.

We agreed to complete the exchange offer not later than 60 days after such effective date, and we further agreed to keep the exchange offer open for a period of not less than 20 business days (or longer if required by applicable law) after the date notice of the exchange offer is mailed to the holders of the Old Notes.

For each Old Note surrendered to us under the exchange offer, the holder of that Old Note will receive a New Note having a principal amount equal to that of the surrendered Old Note. Interest payments on the Notes will be made semi-annually in cash in arrears on March 15 and September 15 of each year, commencing on September 15, 2017. Interest on each New Note will accrue (a) from the later of (i) the last interest payment date on which interest was paid on the Old Note surrendered in exchange for such New Note or (ii) if the Old Note is surrendered for exchange on a date in a period that includes the record date for an interest payment date to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date or (b) if no interest has been paid on such Old Note, from March 15, 2017, the settlement date of the Old Notes.

Based on interpretations by the staff of the SEC set forth in no-action letters issued to third parties, we believe that, subject to the exceptions discussed below, the New Notes issued in exchange for Old Notes may be offered for resale, resold and otherwise transferred by any New Note holder without compliance with the registration and prospectus delivery provisions of the Securities Act, if:

• the holder is not an “affiliate” of ours within the meaning of Rule 405 under the Securities Act;

• the New Notes are acquired in the ordinary course of the holder’s business; and

• the holder does not intend to participate in the distribution of the New Notes.

Holders that are broker-dealers may be deemed “underwriters” within the meaning of the Securities Act in connection with any resale of New Notes acquired in the exchange offer. As a result, the registration rights agreement contemplates that the prospectus for the exchange offer include certain information necessary to allow a broker-dealer who holds Old Notes that were acquired for its own account as a result of market-making activities or other ordinary course trading activities (other than Old Notes acquired directly from us or one of our affiliates) to exchange those Old Notes under the exchange offer and to satisfy the prospectus delivery requirements in connection with resales of New Notes received by that broker-dealer in the exchange offer. The inclusion of such information is needed because any broker-dealer who acquires Old Notes for its own account as a result of market-making activities or other trading activities is required to deliver a prospectus meeting the requirements of the Securities Act. This prospectus covers the offer and sale of the New Notes under the exchange offer and the resale of New Notes received in the exchange offer by any broker-dealer who held Old Notes acquired for its own account as a result of market-making activities or other trading activities other than Old Notes acquired directly from us or one of our affiliates.

25

Any holder who (i) tenders in the exchange offer with the intention of participating in any manner in a distribution of the New Notes or (ii) is a broker-dealer that acquired its Old Notes directly from us and not as a result of market-making activities or other trading activities:

• cannot rely on the position of the staff of the SEC set forth in Exxon Capital Holdings Corp.,SEC No-Action Letter (April 13, 1988); Morgan Stanley & Co. Inc., SEC No-Action Letter (June 5, 1991); Shearman & Sterling, SEC No-Action Letter (July 2, 1993) or similar interpretive letters; and

• must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction.

If, as stated above, a holder cannot rely on the position of the staff of the SEC set forth in “Exxon Capital Holdings Corporation” or similar interpretive letters, any effective registration statement used in connection with a secondary resale transaction must contain the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K under the Securities Act.

Each holder of the Old Notes who desires to exchange Old Notes for the New Notes in the exchange offer will be required to make the representations described below under “—Procedures for Tendering—Your Representations to Us.” Holders that are broker-dealers must acknowledge that they acquired their Old Notes in market-making activities or other trading activities and must deliver a prospectus when they resell the New Notes they acquire in the exchange offer in order not to be deemed an underwriter.

We further agreed to file with the SEC a shelf registration statement to register for public resale of Old Notes and to use commercially reasonable efforts to keep effective such shelf registration statement until the earlier of (i) two years after the settlement date of the Old Notes or (ii) such time as all Old Notes covered by the shelf registration statement have been sold (such earlier time, the “Shelf Effectiveness Period”), if:

• because of any change in law or in currently prevailing interpretations of the staff of the SEC, we are not permitted to effect an exchange offer;

• the exchange offer is not consummated within 365 days of the settlement date of the Old Notes;

• in certain circumstances, the initial purchasers of the Old Notes so request; or

• in the case of any holder that participates in the exchange offer, such holder does not receive New Notes that may be sold without restriction under state and federal securities laws (other than due solely to the status of such holder as an affiliate of ours within the meaning of the Securities Act).

The registration rights agreement provides that if:

(1) on or prior to the 365th day after the settlement date of the Old Notes, (i) the exchange offer has not been consummated or (ii) a shelf registration statement covering resales of the Old Notes (if required by either of the first two bullet points in the immediately preceding paragraph) has not become effective;

(2) we are required to file a shelf registration statement covering resales of the Old Notes pursuant to the third bullet in the immediately preceding paragraph and such shelf registration statement is not declared effective by the later of (i) the 365th day after the settlement date of the Old Notes or (ii) 90 days after the obligation to file such shelf registration statement arose under the registration rights agreement; or

(3) any required shelf registration statement is filed and declared effective but shall thereafter cease to be effective or fail to be usable during the Shelf Effectiveness Period (subject to certain exceptions) (each such event referred to in clauses (1) through (3) above, a “Registration Default”);

then the interest rate on the Old Notes will be increased by 0.25% per annum during the 90-day period immediately following the occurrence of any such Registration Default, and will increase by 0.25% per annum at

26

the end of each subsequent 90-day period, but in no event will the increase exceed 1.00% per annum. The additional interest shall accrue until the exchange offer is completed or the shelf registration statement is declared effective (or again becomes effective) under the Securities Act, as applicable. The amount of additional interest payable pursuant to the provisions described above will not increase more than once in any of the 90 day periods described above if more than one of the Registration Defaults have occurred and are continuing.

In the event that a shelf registration statement covering resales of the Old Notes is filed, we will provide to each holder whose Old Notes are registered under such shelf registration statement copies of the prospectus that is a part of such shelf registration statement, notify each such holder when such shelf registration statement has become effective and take certain other actions as are required to permit unrestricted resales of the Old Notes. A holder that sells Old Notes pursuant to a shelf registration statement will be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under Securities Act in connection with such sales and will be bound by the provisions of the registration rights agreement that are applicable to such a holder (including certain indemnification rights and obligations). In addition, we may require each holder whose Old Notes are registered under such shelf registration statement to furnish us with such information regarding such holder and the proposed disposition by such holder of its Old Notes.

If we effect the registered exchange offer, we will be entitled to close the registered exchange offer after 20 business days (or longer if required by applicable law) following the date notice of the exchange offer is mailed to the holders of the Old Notes as long as we have accepted all Old Notes validly tendered in accordance with the terms of the exchange offer. Except in the limited circumstances set forth in the registration rights agreement, after consummation of the exchange offer, holders of Old Notes which are not prohibited from participating in the exchange offer will have no registration or exchange rights under the registration rights agreement. See “—Consequences of Failure to Exchange.”

This summary of the material provisions of the registration rights agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the registration rights agreement, which is incorporated by reference into this prospectus.

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 before 5:00 p.m., New York City time, on the expiration date. We will issue New Notes in a 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 minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The exchange offer is not conditioned on any minimum aggregate principal amount of Old Notes being tendered for exchange.

As of the date of this prospectus, $325 million in aggregate principal amount of the Old Notes is outstanding. This prospectus and the letter of transmittal are being sent to all registered holders of 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 (the “Exchange Act”), and the rules and regulations of the SEC. Old Notes that the holders do not tender for exchange in the exchange offer will remain outstanding and continue to accrue interest. These Old Notes will continue to be entitled to the rights and benefits such holders have under the Indenture.

27

We will be deemed to have accepted for exchange properly tendered Old Notes when we have given oral (promptly followed in writing) 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. It is important that you read the section labeled “—Fees and Expenses” for more details regarding fees and expenses incurred in the exchange offer.

We will return any Old Notes that we do not accept for exchange for any reason without expense to their tendering holder 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                 , 2018, unless, in our sole discretion, we extend it.

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 (promptly followed in writing) or written notice of an extension to the holders. During any extensions, all Old Notes previously tendered will remain subject to the exchange offer, and we may accept them for exchange.

In order to extend the exchange offer, we will notify the exchange agent orally (promptly followed in writing) or in writing of any extension. We will notify the registered holders of Old Notes of the extension 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 delay accepting for exchange any Old Notes,

• to extend the exchange offer, or

• to terminate the exchange offer,

by giving oral (promptly followed in writing) or written notice of the 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 delay in acceptance, extension, termination, or amendment will be followed promptly by oral (promptly followed in writing) or written notice thereof to the registered holders of Old Notes. If we amend the exchange offer in a manner that we determine to constitute a material change, we will promptly disclose that amendment by means of a prospectus supplement. The supplement will be distributed to the registered holders of the Old Notes. Depending on the significance of the amendment and the manner of disclosure to the registered holders, we may extend the exchange offer. In the event of a material change in the exchange offer, including the waiver by us of a material condition, we will extend the exchange offer period if necessary so that at least five business days remain in the exchange offer following notice of the material change.

28

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 applicable interpretations of the staff of the SEC. Similarly, we may terminate the exchange offer as provided in this prospectus before accepting Old Notes for exchange in the event of a potential violation.

In addition, 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 “—Purpose and Effect of the Exchange Offer,” “—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.

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, on the occurrence of any of the conditions to the exchange offer specified above. We will give prompt oral (promptly followed in writing) 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 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. These rights will be deemed ongoing rights that we may assert at any time or at various times.

In addition, we will not accept for exchange any Old Notes tendered, and will not issue New Notes in exchange for these Old Notes, if at such time any stop order has been threatened or is in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the Indenture under the Trust Indenture Act of 1939, as amended.

Procedures for Tendering

In order to participate in the exchange offer, you must properly tender your Old Notes to the exchange agent as described below. 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 are not required to notify you of 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 set forth in “Prospectus Summary—The Exchange Offer—Exchange Agent.”

All of the Old Notes were issued in book-entry form, and all of the Old Notes are currently represented by global certificates held for the account of DTC. We have confirmed with DTC that the Old Notes may be tendered using the Automated Tender Offer Program (“ATOP”) instituted by DTC. 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 be deemed to 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.

29

Determinations Under the Exchange Offer

We will determine in our sole discretion all questions as to the validity, form, eligibility (including time of receipt), acceptance of tendered Old Notes, and withdrawal of tendered Old Notes. Our determination will be final and binding. We reserve the absolute right to reject any Old Notes not properly tendered or any Old Notes our acceptance of which would, in 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 the 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, unless otherwise provided in the letter of transmittal, promptly following the expiration date.

When We Will Issue New Notes

In all cases, we will issue New Notes for Old Notes that we have accepted for exchange under the exchange offer only after the exchange agent timely receives:

• a book-entry confirmation of the 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. The non-exchanged Old Notes will be credited to an account maintained with DTC. These actions will occur promptly after 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 are not engaging and do not intend to engage in the distribution of Old Notes or New Notes within the meaning of the Securities Act;

• you have no arrangement or understanding with any person to participate in the distribution of Old Notes or New Notes within the meaning of the Securities Act;

• you are not our “affiliate,” as defined in Rule 405 of the Securities Act; and

• if you are a broker-dealer, that you 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 and that you will deliver a prospectus (or to the extent permitted by law, make available a prospectus) 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 before 5:00 p.m., New York City time, on the expiration date. For a withdrawal of a tender to be effective, a written or

30

facsimile transmission notice of withdrawal, or a properly transmitted “request message” through ATOP, must be received by the Exchange Agent prior to the Expiration Date at its address set forth below under “Prospectus Summary—Exchange Offer—Exchange Agent.” Any such written or facsimile-transmitted notice must:

• set forth the name of the tendering holder;

• the principal amount of Old Notes delivered for exchange; and

• a statement that such holder is withdrawing its election to have such Old Notes exchanged.

We will determine all questions as to the validity, form, eligibility, and time of receipt of 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.

Any Old Notes that have been tendered for exchange but are not exchanged for any reason will be credited to an account maintained with DTC for the Old Notes. This crediting will take place as soon as practicable after withdrawal, rejection of tender 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 before 5:00 p.m., New York City time, on the expiration date.

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 fax, telephone, electronic mail 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, without limitation:

• all SEC and stock exchange registration and filing fees;

• all fees and expenses of compliance with state “blue sky” or securities laws;

• word processing, printing and distribution expenses; and

• our legal fees and accounting fees.

Transfer Taxes

We will pay all transfer taxes, if any, applicable to the exchange of Old Notes under the exchange offer. The 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 under the exchange offer.

Consequences of Failure to Exchange

If you do not exchange your Old Notes for New Notes under the exchange offer, you will remain subject to the existing restrictions on transfer of the Old Notes. In general, you may not offer or sell the Old Notes unless the offer or sale is either registered under the Securities Act or exempt from the registration under the Securities Act and applicable state securities laws. Except in the limited circumstances required by the registration rights agreement, we do not intend to register resales of the Old Notes under the Securities Act.

31

In addition, after the consummation of the exchange offer, it is anticipated that the outstanding principal amount of the Old Notes available for trading will be significantly reduced. The reduced float may adversely affect the liquidity and market price of the Old Notes. A smaller outstanding principal amount of Old Notes available for trading may also make the price of the Old Notes more volatile.

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 less any bond discount, 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

Participation in the exchange offer is voluntary, and you should carefully consider 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.

RATIO OF EARNINGS TO FIXED CHARGES

The table below shows our ratio of earnings to fixed charges for the periods indicated. For purposes of this computation, “earnings” include pre-tax income from continuing operations before adjustment for non-controlling interests in consolidated subsidiaries or income or loss from equity investees (including gain on issuance of common units by equity method investee), fixed charges, amortization of capitalized interest, distributed income of equity investees and our share of pre-tax losses of equity investees for which charges arising from guarantees are included in fixed charges, less interest capitalized, preference security dividend requirements of consolidated subsidiaries and the minority interest in pre-tax income of subsidiaries that have not incurred fixed charges. “Fixed charges” include interest (whether expensed or capitalized), amortized premiums, discounts and capitalized expenses related to indebtedness, an estimate of the interest within rental expense and preference security dividend requirements of consolidated subsidiaries. No shares of preferred stock were outstanding during the periods indicated.

USE OF PROCEEDS

The exchange offer is intended to satisfy our obligations under the registration rights agreement. We will not receive any 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 form and terms of the New Notes are identical in all respects to the form and terms of the Old Notes, except that the New Notes will be registered under the Securities Act and will not have restrictions on transfer, registration rights or provisions for additional interest. 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 outstanding indebtedness.

34

DESCRIPTION OF THE NOTES

General

We issued the Old Notes and will issue the New Notes under the Indenture. The terms of the New Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

If the exchange offer contemplated by this prospectus is consummated, holders of Old Notes who do not exchange those Old Notes for New Notes in the exchange offer will vote together with holders of New Notes for all relevant purposes under the Indenture. In that regard, the Indenture requires that certain actions by the holders thereunder must be taken, and certain rights must be exercised, by specified minimum percentages of the aggregate principal amount of the outstanding securities issued under the Indenture. In determining whether holders of the requisite percentage in principal amount 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 such Old Notes and the New Notes will vote together as a single class for all such purposes. Accordingly, all references herein to specified percentages in aggregate principal amount of the Notes outstanding shall be deemed to mean, at any time after the exchange offer is consummated, such percentages in aggregate principal amount of the Old Notes and the New Notes then outstanding.

The issuance of New Notes in this offering will be limited to $325,000,000 in aggregate principal amount. The Company may issue additional Notes under the Indenture from time to time after this offering (the “Additional Notes”), subject to the covenant described below under “Certain Covenants—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.” Any Additional Notes will be part of the same series as the New Notes that we are currently offering and will vote on all matters with the holders of the Notes. Unless the context requires otherwise, references to “Notes” include the Old Notes, the New Notes and any Additional Notes that are actually issued.

You can find the definitions of certain capitalized terms used in this description under the subheading “Certain Definitions.” In this description, the “Company,” “we” and “our” refer only to SemGroup Corporation and not any of its Subsidiaries.

The following description is only a summary of the material provisions of the Notes and the Indenture. This summary is not a complete description of all the provisions of the Notes and is subject to, and is qualified in its entirety by reference to, the Notes and the Indenture. For more information, we refer you to the Notes and the Indenture, all of which you may request copies of at our address set forth under the heading “Where You Can Find More Information; Incorporation by Reference.”

Brief Description of the Notes

The Notes

• are unsecured senior obligations of the Company;

• rankpari passu in right of payment with all existing and future Senior Indebtedness of the Company, including Indebtedness under the Senior Credit Facility and the Company’s existing senior notes;

• are effectively subordinated to all Secured Indebtedness of the Company to the extent of the value of the collateral securing such Indebtedness, including Indebtedness under the Senior Credit Facility;

• are structurally subordinated to all existing and future claims of creditors (including trade creditors) and holders of Preferred Stock of Subsidiaries of the Company that do not guarantee the Notes, including our Unrestricted Subsidiaries;

35

• rank senior in right of payment to any future Subordinated Indebtedness of the Company; and

• are guaranteed on a senior unsecured basis by the Subsidiary Guarantors, including any of our subsidiaries that guarantee the Senior Credit Facility.

Principal, Maturity and Interest

Interest on the Notes accrues at the rate of 6.375% per annum and will be payable in cash semi-annually in arrears on each March 15 and September 15, commencing September 15, 2017. The Company will make each interest payment to the Holders of record of the Notes on the immediately preceding March 1 and September 1. Interest on the New Notes will accrue (a) from the later of (i) the last interest payment date on which interest was paid on the Old Note surrendered in exchange for such New Note or (ii) if the Old Note is surrendered for exchange on a date in a period that includes the record date for an interest payment to occur on or after the date of such exchange and as to which interest will be paid, the date of such interest payment date or (b) if no interest has been paid on such Old Note, from the Issue Date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The Notes will mature on March 15, 2025. The Notes will be issued in denominations of $2,000 and any integral multiples of $1,000 in excess of $2,000. If an interest payment date or the maturity date falls on a day that is not a Business Day, the related payment of principal or interest will be made on the next succeeding Business Day and no interest shall accrue for the intervening period.

Subsidiary Guarantees

Each Subsidiary Guarantor, as a primary obligor and not merely as a surety, jointly and severally, irrevocably and unconditionally guarantees the Company’s obligations under the Indenture and the Notes on a senior unsecured basis. All of the Restricted Subsidiaries that are guarantors under the Senior Credit Facility on the Issue Date initially guaranteed the Notes. Each Subsidiary Guarantee of the Notes is a general unsecured obligation of the applicable Subsidiary Guarantor, rankspari passuin right of payment with all existing and future Senior Indebtedness of such Subsidiary Guarantor, including such Subsidiary Guarantor’s guarantee of the Senior Credit Facility and the guarantee of the Company’s existing senior notes, is effectively subordinated to all Secured Indebtedness of such Subsidiary Guarantor, including such Subsidiary Guarantor’s guarantee of the Senior Credit Facility, to the extent of the value of the collateral securing such Indebtedness, and ranks senior in right of payment to any future Subordinated Indebtedness of such Subsidiary Guarantor. The Subsidiary Guarantee of such Subsidiary Guarantor is structurally subordinated to all existing and future claims of creditors (including trade creditors) and holders of Preferred Stock of Subsidiaries of such Subsidiary Guarantor that do not guarantee the Notes, including any Unrestricted Subsidiaries.

As of the date of this prospectus, all of our Subsidiaries other than SemMexico Materials HC S. de R.L. de C.V., White Cliffs Pipeline, L.L.C., Maurepas Holdings, LLC, Beachhead Holdings, LLC and their Subsidiaries are Restricted Subsidiaries. Under the circumstances described below under “Certain Covenants—Limitation on Restricted Payments” and the definition of “Unrestricted Subsidiary,” however, we will be permitted to designate certain of our existing and future Subsidiaries as “Unrestricted Subsidiaries.” Our Unrestricted Subsidiaries are not subject to the restrictive covenants in the Indenture. Our Unrestricted Subsidiaries do not guarantee the Notes. As of September 30, 2017, the Unrestricted Subsidiaries had consolidated total liabilities (excluding intercompany liabilities) of approximately $1,402.5 million, including trade payables, and consolidated total assets of approximately $2,569.4 million, which represents 47.9% of the consolidated total assets of the Company and its Subsidiaries. In addition, on a pro forma basis after giving effect to the HFOTCO Acquisition and the SemMexico Disposition, our Unrestricted Subsidiaries generated approximately 8.8% of our consolidated revenues for the nine months ended September 30, 2017.

We previously owned a 50.0% membership interest in Glass Mountain Pipeline, LLC that we accounted for as an unconsolidated subsidiary for financial accounting purposes. However, Glass Mountain Pipeline, LLC was not classified as a “Subsidiary” for purposes of the Indenture, and therefore was not subject to the restrictive

36

covenants in the Indenture and did not guarantee the Notes. To the extent Glass Mountain Pipeline, LLC had become a Subsidiary under the Indenture, it would have become an Unrestricted Subsidiary. As of September 30, 2017, Glass Mountain Pipeline, LLC had total assets of $228.7 million and members’ equity of $221.0 million. On November 8, 2017, we entered into an agreement to sell our 50% interest in Glass Mountain Pipeline LLC and on December 22, 2017, we completed the sale. See “Prospectus Summary—Recent Developments—Sale of Interest in Glass Mountain Pipeline.”

Each Subsidiary Guarantee contains a provision intended to limit the Subsidiary Guarantor’s liability thereunder to the maximum amount that it could incur without causing the incurrence of obligations under its Subsidiary Guarantee to be a fraudulent transfer. This provision may not, however, be effective to protect a Subsidiary Guarantee from being voided under fraudulent transfer law or may reduce the Subsidiary Guarantor’s obligation to an amount that effectively makes its Subsidiary Guarantee worthless. See “Risk Factors—Risks Related to Our Indebtedness and the Notes—Federal and state statutes allow courts, under specific circumstances, to void the Notes or the guarantees and require noteholders to return payments received from us or the subsidiary guarantors.”

Each Subsidiary Guarantor may consolidate with or merge into or sell all or substantially all its assets to (A) the Company or another Subsidiary Guarantor without limitation or (B) any other Persons upon the terms and conditions set forth in the Indenture. See “Certain Covenants—Merger, Consolidation or Sale of All or Substantially All Assets.”

The Subsidiary Guarantee of a Subsidiary Guarantor will automatically and unconditionally be released and discharged upon:

(1) (a) the sale, disposition or other transfer (including through merger or consolidation) of all of the Capital Stock (or any sale, disposition or other transfer of Capital Stock following which such Subsidiary Guarantor is no longer a Restricted Subsidiary), or all or substantially all the assets, of such Subsidiary Guarantor (other than a sale, disposition or other transfer to a Restricted Subsidiary) if such sale, disposition or other transfer is made in compliance with the applicable provisions of the Indenture;

(b) the designation by the Company of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with the provisions of the Indenture described under “Certain Covenants—Limitation on Restricted Payments” and the definition of “Unrestricted Subsidiary;”

(c) the release or discharge of such Subsidiary Guarantor from its guarantee of Indebtedness under the Senior Credit Facility or the guarantee that resulted in the obligation of such Subsidiary Guarantor to guarantee the Notes, if such Subsidiary Guarantor would not then otherwise be required to guarantee the Notes pursuant to the covenant described under “Certain Covenants—Future Subsidiary Guarantors” (treating any guarantees of such Subsidiary Guarantor that remain outstanding as incurred at least 30 days prior to such release or discharge); or

(d) the exercise by the Company of its legal defeasance option or its covenant defeasance option, as described under “Legal Defeasance and Covenant Defeasance” or if the Company’s obligations under the Indenture are discharged in accordance with the terms of the Indenture; and

(2) in the case of clause (1)(a) above, the release or discharge of such Subsidiary Guarantor from its guarantee, if any, of and all pledges and security, if any, granted in connection with, the Senior Credit Facility and any other Indebtedness of the Company or any Restricted Subsidiary.

Ranking

Secured Indebtedness versus Notes

Payments of principal of, and premium, if any, and interest on, the Notes and the payment of any Subsidiary Guarantee rankpari passu in right of payment with all Senior Indebtedness of the Company or the relevant

37

Subsidiary Guarantor, as the case may be, including the obligations of the Company and such Subsidiary Guarantor under the Senior Credit Facility. However, the Notes and Subsidiary Guarantees are effectively subordinated in right of payment to all of the existing and future Secured Indebtedness and other secured obligations of the Company or the relevant Subsidiary Guarantor, as the case may be, to the extent of the value of the assets securing such Indebtedness and other secured obligations. As of September 30, 2017:

(1) the Company’s Senior Indebtedness (excluding unused commitments, undrawn letters of credit and any secured Hedging Obligations) was approximately $1,707.0 million, of which $332 million, consisting of Indebtedness under the Senior Credit Facility, was Secured Indebtedness; and

(2) the Subsidiary Guarantors’ Senior Indebtedness (excluding unused commitments, undrawn letters of credit and any secured Hedging Obligations) was approximately $1,707.0 million in the aggregate, of which $332 million, consisting of their respective guarantees with respect to the Senior Credit Facility, was Secured Indebtedness.

In addition, the Company had approximately $628.6 million of unused commitments (excluding undrawn letters of credit of $39.4 million) under the Senior Credit Facility and approximately $51.1 million of secured Bilateral Letters of Credit, all of which would constitute Secured Indebtedness when drawn. Although the Indenture contains limitations on the amount of additional Senior Indebtedness that the Company and its Restricted Subsidiaries may incur and the amount of additional Secured Indebtedness the Company and the Subsidiary Guarantors may incur, under certain circumstances the amount of such Senior Indebtedness and Secured Indebtedness could be substantial. See “Certain Covenants—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock” and “Certain Covenants—Liens.”

In addition, certain of our Hedging Obligations constitute Secured Indebtedness. To the extent prices of the relevant commodities increase, the amount of this Secured Indebtedness could increase significantly. We expect to incur additional secured Hedging Obligations as part of our ongoing commodity risk management activities.

Liabilities of Subsidiaries versus Notes

Substantially all of our operations are conducted through our Subsidiaries. Some of our Subsidiaries are not guaranteeing the Notes, and Subsidiary Guarantees may be released under certain circumstances, as described under “Subsidiary Guarantees.” In addition, our future Subsidiaries may not be required to guarantee the Notes, and our Unrestricted Subsidiaries are not required to guarantee the Notes. Claims of creditors of such non-guarantor Subsidiaries, including trade creditors and creditors holding indebtedness or guarantees issued by such non-guarantor Subsidiaries, and claims of holders of Preferred Stock of such non-guarantor Subsidiaries, generally will have priority with respect to the assets and earnings of such non-guarantor Subsidiaries over the claims of our creditors, including Holders. Accordingly, the Notes will be structurally subordinated to claims of creditors (including trade creditors) and holders of Preferred Stock, if any, of such non-guarantor Subsidiaries.

Although the Indenture limits the incurrence of Indebtedness and Preferred Stock by our Restricted Subsidiaries, such limitation is subject to a number of significant qualifications. Moreover, the Indenture does not impose any limitation on the incurrence by Restricted Subsidiaries of liabilities that are not considered Indebtedness or Preferred Stock under the Indenture, such as trade payables. See “Certain Covenants—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.”

Although the Indenture imposes requirements upon certain sales, conveyances and other transfers of assets by the Company and the Restricted Subsidiaries, such requirements do not prohibit such sales, conveyances or transfers but generally only require that the Company or the Restricted Subsidiary receive fair market value for the asset, that a designated portion of the consideration is received in cash or, in certain cases, Cash Equivalents and that the Company or the Restricted Subsidiaries apply the net cash proceeds for specified purposes, including the retirement of certain Indebtedness or as an investment in additional assets. To the extent assets are transferred to Unrestricted Subsidiaries, including MLPs and GPs, those assets will no longer constitute assets of the

38

Company or the Restricted Subsidiaries, and the EBITDA associated with these assets will not be EBITDA of the Company and the Restricted Subsidiaries.

Mandatory Redemption; Offer to Purchase; Open Market Purchases

The Company is not required to make any mandatory redemption or sinking fund payments with respect to the Notes. However, under certain circumstances, the Company may be required to offer to purchase Notes as described under “Repurchase at the Option of Holders.”

The Company may from time to time acquire Notes by means other than a redemption, whether by tender offer, in open market purchases, through negotiated transactions or otherwise, in accordance with applicable securities laws.

Optional Redemption

Except as described below, the Notes are not redeemable at the Company’s option prior to March 15, 2020. From and after March 15, 2020, the Company may redeem the Notes, in whole or in part, upon not less than 15 nor more than 60 days’ prior notice sent electronically or mailed by first-class mail to each Holder’s registered address, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon to, but not including, the applicable redemption date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, if redeemed during the twelve-month period beginning on March 15 of each of the years indicated below:

Year	Percentage
2020		103.188	%
2021		101.594	%
2022 and thereafter		100.000	%

Prior to March 15, 2020, the Company may, at its option, on one or more occasions, redeem up to 35% of the sum of the original aggregate principal amount of Notes (and the original principal amount of any Additional Notes) issued under the Indenture at a redemption price equal to 106.375% of the aggregate principal amount thereof,plus accrued and unpaid interest thereon to, but not including, the redemption date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date, with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings of the Company or any direct or indirect parent of the Company to the extent such net proceeds are contributed to the Company;provided that:

• at least 65% of the sum of the aggregate principal amount of Notes originally issued under the Indenture and the original principal amount of any Additional Notes issued under the Indenture remain outstanding immediately after the occurrence of each such redemption; and

• each such redemption occurs within 180 days of the date of closing of each such Equity Offering.

At any time prior to March 15, 2020, the Company may also redeem all or a part of the Notes, upon not less than 15 nor more than 60 days’ prior notice, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, the redemption date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date.

Selection and Notice

If the Company is redeeming less than all of the Notes at any time, the Trustee will select the Notes to be redeemed (a) if the Notes are listed on any national securities exchange (and such listing is known to the

39

Trustee), in compliance with the requirements of the principal national securities exchange on which such Notes are listed, or (b) if the Notes are not so listed, on apro rata basis to the extent practicable or by lot or by such other method as may be required by the procedures of DTC;provided that no Notes of $2,000 or less shall be redeemed in part.

Notices of redemption shall be sent electronically or be mailed by first-class mail, postage prepaid, at least 15 days but not more than 60 days before the redemption date to each Holder at such Holder’s registered address, except that notices of redemption may be sent electronically or 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. If any Note is to be redeemed in part only, any notice of redemption that relates to such Note shall state the portion of the principal amount thereof to be redeemed.

A new Note in principal amount equal to the unredeemed portion of any Note redeemed in part will be issued in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become due and payable on the date fixed for redemption. On and after the redemption date, unless the Company defaults in payment of the redemption price, interest shall cease to accrue on Notes or portions thereof called for redemption.

In connection with any redemption of the Notes (including with the net cash proceeds of an Equity Offering), any such redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of a sale of common stock or other corporate transaction (including any related Equity Offering). In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Company’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed.

Repurchase at the Option of Holders

Change of Control Triggering Event

If a Change of Control Triggering Event occurs, the Company will be required to make an offer to purchase all of the Notes pursuant to the offer described below (the “Change of Control Offer”) at a price in cash (the “Change of Control Payment”) equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest to, but not including, the date of purchase, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date. Within 30 days following any Change of Control Triggering Event, the Company will send notice of such Change of Control Offer by first-class mail or electronically, to each Holder to the address of such Holder appearing in the security register with a copy to the Trustee, with the following information:

(1) a description of the transaction or transactions and identification of the ratings decline that together constitute a Change of Control Triggering Event and stating that a Change of Control Offer is being made pursuant to the covenant entitled “Change of Control Triggering Event,” and that all Notes properly tendered pursuant to such Change of Control Offer will be accepted for payment;

(2) the purchase price and the purchase date, which will be no earlier than 15 days nor later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

(3) any Note not properly tendered will remain outstanding and continue to accrue interest;

(4) unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on the Change of Control Payment Date;

(5) Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse

40

of the Notes completed, to the paying agent specified in the notice at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) Holders will be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes;providedthat the paying agent receives, not later than the close of business on the last day of the offer period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased; and

(7) Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 or an integral multiple of $1,000 in excess of $2,000.

While the Notes are in global form and the Company makes an offer to purchase all of the Notes pursuant to the Change of Control Offer, a Holder may exercise its option to elect for the purchase of the Notes through the facilities of DTC, subject to its rules and regulations.

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 such laws or regulations are applicable in connection with the repurchase of the Notes pursuant to a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Indenture, or compliance with the Change of Control Triggering Event provisions of the Indenture would constitute a violation of any such law or regulation, the Company will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Indenture by virtue thereof.

On the Change of Control Payment Date, the Company will, to the extent permitted by law,

(1) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer;

(2) deposit with the paying agent an amount equal to the aggregate Change of Control Payment in respect of all Notes or portions thereof so tendered; and

(3) deliver, or cause to be delivered, to the Trustee for cancellation the Notes so accepted together with an Officers’ Certificate stating that such Notes or portions thereof have been tendered to and purchased by the Company.

The paying agent will promptly mail to each Holder the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail to each Holder a new Note equal in principal amount to the unpurchased portion of the Notes surrendered;providedthat each such 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 Payment Date.

Except as described above with respect to a Change of Control Triggering Event, the Indenture will not contain provisions that permit the Holders to require the Company to repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

The Senior Credit Facility provides, and future credit agreements or other agreements to which the Company becomes a party may provide, that certain change of control events with respect to the Company (including a Change of Control) would constitute a default thereunder and certain of these agreements may prohibit the Company from purchasing any Notes as a result of a Change of Control Triggering Event. The exercise of Holders of the Notes of their right to require the Company to repurchase the Notes upon a Change of Control Triggering Event could cause a default under those agreements, even if the Change of Control Triggering

41

Event itself does not, due to the financial effect of such repurchase or other prepayments on the Company. In the event a Change of Control Triggering Event occurs at a time when the Company is prohibited from purchasing the Notes, the Company could seek the consent of its lenders to permit the purchase of the Notes or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such consent or repay such borrowings, the Company will remain prohibited from purchasing the Notes. In such case, the Company’s failure to purchase tendered Notes would constitute an Event of Default under the Indenture that could, in turn, constitute a default under other indebtedness. If the Company experiences a change of control that triggers a default under the Senior Credit Facility or cross defaults under other Indebtedness, the Company could seek a waiver of such defaults or seek to refinance the Indebtedness outstanding under the Senior Credit Facility and such other Indebtedness. In the event the Company does not obtain such a waiver or refinance the Indebtedness outstanding under the Senior Credit Facility and such other Indebtedness, such defaults could result in amounts outstanding under the Senior Credit Facility and such other Indebtedness being declared due and payable. Our ability to pay cash to the Holders following the occurrence of a Change of Control Triggering Event may be limited by our then existing financial resources. See “Risk Factors—Risks Related to Our Indebtedness and the Notes—We may be unable to purchase your notes upon a change of control triggering event.” Therefore, sufficient funds may not be available when necessary to make any required repurchases.

The Company will not be required to make a Change of Control Offer following a Change of Control Triggering Event if (1) 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 validly tendered and not withdrawn under such Change of Control Offer or (2) notice of redemption has been given pursuant to the Indenture as described above under “Optional Redemption,” unless and until there is a default in payment of the applicable redemption price. A Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

The Change of Control Triggering Event purchase feature of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of the Company and, thus, the removal of incumbent management. The Change of Control Triggering Event purchase feature is a result of negotiations between the Company and the Initial Purchasers. We have no present intention to engage in a transaction involving a Change of Control Triggering Event, although it is possible that we could decide to do so in the future. Subject to the limitations discussed below, we could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control Triggering Event under the Indenture, but that could increase the amount of Indebtedness outstanding at such time or otherwise affect our capital structure or credit ratings. Restrictions on our ability to incur additional Indebtedness are contained in the covenant described under “Certain Covenants—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.” Such restrictions can be waived with the consent of the holders of a majority in principal amount of the Notes then outstanding. Except for the limitations contained in such covenant, however, the Indenture will not contain any covenants or provisions that may afford Holders protection in the event of a highly leveraged transaction.

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 (or the third party making the Change of Control Offer as described above) purchases all of the Notes held by such Holders, the Company will have the right, upon not less than 15 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, but not including, the date of redemption, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date.

42

The definition of “Change of Control” includes a disposition of all or substantially all of the assets of the Company and its Restricted Subsidiaries, taken as a whole, to any Person. 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 a disposition of “all or substantially all” of the assets of the Company and its Restricted Subsidiaries, taken as a whole. As a result, it may be unclear as to whether a Change of Control has occurred and whether a Holder may require the Company to make an offer to repurchase the Notes as described above. See “Risk Factors”—Risks Related to our Indebtedness and the Notes—Holders of the Notes may not be able to determine when a change of control giving rise to their right to have the Notes repurchased has occurred following a sale of “substantially all” of our assets.”

The provisions under the Indenture relative to the Company’s obligation to make an offer to repurchase the Notes as a result of a Change of Control may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes.

Asset Sales

The Indenture provides that the Company will not, and will not permit any Restricted Subsidiary to, cause, make or suffer to exist an Asset Sale (including any MLP Asset Transfer) unless:

(1) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as determined in good faith by the Company) of the assets or Equity Interests sold or otherwise disposed of; and

(2) other than in the case of a Permitted Asset Swap, at least 75% of the consideration thereof received by the Company or such Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents;providedthat the amount of:

(a) any liabilities (as shown on the Company’s most recent consolidated balance sheet or in the notes thereto) of the Company or such Restricted Subsidiary, other than liabilities that are by their terms subordinated to the Notes, that are assumed by the transferee of any such assets (or a third party on behalf of the transferee) and for which the Company or such Restricted Subsidiary has been validly released by all relevant creditors in writing,

(b) any securities, notes or other obligations or assets received by the Company or such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents (to the extent of the cash or Cash Equivalents received) within 180 days following the closing of such Asset Sale,

(c) any Designated Noncash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Noncash Consideration received pursuant to this clause (c) that is at that time outstanding, not to exceed the greater of (x) $125.0 million and (y) 4.0% of Total Assets at the time of the receipt of such Designated Noncash Consideration, with the fair market value of each item of Designated Noncash Consideration being measured at the time received and without giving effect to subsequent changes in value, and

(d) any investment referred to in clause (2) of the second succeeding paragraph (other than pursuant to clause (c) thereof),

shall be deemed to be cash for purposes of this provision and for no other purpose; provided, that in the case of an MLP Asset Transfer, in lieu of the requirement in clause (2) above, the Company, at its election, may meet the following requirements:

(a) after such MLP Asset Transfer and as a result thereof, (x) the Company and its Restricted Subsidiaries shall have received an amount of cash and Designated Noncash Consideration permitted

43

by clause (c) above attributable to such MLP Asset Transfer (as a result of (i) the receipt of cash proceeds and Designated Noncash Consideration as all or a portion of the consideration for such MLP Asset Transfer or (ii) the repayment of intercompany indebtedness, owed by a Subsidiary of the Company, transferred or assumed as part of such MLP Asset Transfer) at least equal to 50% of the fair market value (as determined in good faith by the Company based on values that could be obtained in an arms’ length transaction) of (A) the assets and property transferred or (B) in the case of a transfer of any Equity Interests of a Person, such Person at the time of such MLP Asset Transfer (it being understood that, in the case of a transfer of less than all of the Equity Interests of a Person, the value of such Person shall be determined at the time of the first MLP Asset Transfer constituting part of such MLP Asset Transfer (as if all the Equity Interests in such Person were transferred at the time of such first MLP Asset Transfer, and the cash requirement set forth in this clause shall be satisfied on that basis in connection with such first MLP Asset Transfer) and there shall be no such additional cash attributable to such MLP Asset Transfer required for any subsequent transfer of Equity Interests of such Person constituting part of the MLP Asset Transfer) (in each case of the foregoing clauses (A) and (B), assuming such assets or Person, as applicable, operates as a going concern), with the balance of the consideration received by the Company and its Restricted Subsidiaries for such MLP Asset Transfer consisting solely of Equity Interests in the applicable MLP and (y) immediately after giving effect to such MLP Asset Transfer on a pro formabasis, the Company could incur $1.00 of additional Indebtedness under the provisions of the first paragraph of the covenant described under “Certain Covenants—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock”; and

(b) no Default shall have occurred and be continuing or would occur as a consequence thereof.

For purposes of calculating the fair market value of any assets or property transferred to any Person, any Person and any Equity Interests in a Person with respect to any MLP Asset Transfer, any Indebtedness that is owed by such Person to the Company or any Restricted Subsidiary shall be disregarded and shall not be reflected in such calculation to reduce the fair market value of such assets or property, Person or Equity Interests in such Person, as the case may be.

Within 365 days after any of the Company’s or any Restricted Subsidiary’s receipt of the Net Proceeds of any Asset Sale (including any MLP Asset Transfer), the Company or such Restricted Subsidiary may, at its option, apply the Net Proceeds from such Asset Sale:

(1) to repay, redeem or repurchase Senior Indebtedness of the Company or any Restricted Subsidiary; or

(2) to an investment in (a) any one or more businesses;providedthat such investment in any business is in the form of the acquisition of Capital Stock and results in the Company or any Restricted Subsidiary owning an amount of the Capital Stock of such business such that it constitutes a Restricted Subsidiary, (b) properties, (c) capital expenditures and (d) acquisitions of other assets, that in each of (a), (b), (c) and (d) are used or useful in a Similar Business or replace the businesses, properties and assets that are the subject of such Asset Sale.

Any Net Proceeds from any Asset Sale that are not invested or applied in accordance with the preceding paragraph within 365 days from the date of the receipt of such Net Proceeds will be deemed to constitute “Excess Proceeds”;provided that if during such 365-day period the Company or a Restricted Subsidiary enters into a definitive binding agreement committing it to apply such Net Proceeds in accordance with the requirements of clause (2) of the preceding paragraph after such 365th day, such 365-day period will be extended with respect to the amount of Net Proceeds so committed, but such extension will in no event be for a period longer than 180 days until such Net Proceeds are required to be applied in accordance with such agreement (or, if such agreement is terminated before such Net Proceeds are applied, then such Net Proceeds shall constitute Excess Proceeds from and after the date of such termination). When the aggregate amount of such Excess Proceeds exceeds

44

$50.0 million, the Company will be required to make an offer to all Holders and, if required by the terms of any other Senior Indebtedness, to the holders of such other Senior Indebtedness (other than with respect to Hedging Obligations) (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of Notes and such other Senior Indebtedness that is an integral multiple of $1,000 (subject to any required minimum denominations) that may be purchased out of such Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest to, but not including, the date fixed for the closing of such offer, in accordance with the procedures set forth in the Indenture. The Company will commence an Asset Sale Offer with respect to such Excess Proceeds within ten Business Days after the date that such Excess Proceeds exceed $50.0 million by mailing the notice required pursuant to the terms of the Indenture, with a copy to the Trustee. The Company may satisfy the foregoing obligations with respect to any Net Proceeds from an Asset Sale by making an Asset Sale Offer with respect to such Net Proceeds prior to the expiration of the relevant 365 days (or such longer period provided above) or with respect to Excess Proceeds of $50.0 million or less.

To the extent that the aggregate amount of Notes and such other Senior Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company may use any remaining Excess Proceeds for any purpose not prohibited by the Indenture. If the aggregate principal amount of Notes and other Senior Indebtedness surrendered by the holders thereof exceeds the amount of Excess Proceeds, the Trustee shall select or cause to be selected the Notes and the Company or agent for such other Senior Indebtedness shall select such other Senior Indebtedness to be purchased on apro rata basis based on the principal amount (or accreted value, if applicable) of the Notes or such other Senior Indebtedness tendered. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds related to such Asset Sale Offer shall be reset at zero.

Pending the final application of any Net Proceeds pursuant to this covenant, the Company or the applicable Restricted Subsidiary may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such Net Proceeds in any manner not prohibited by the Indenture.

The procedures for an Asset Sale Offer will be substantially the same as for a Change of Control Offer. 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 such laws or regulations are applicable in connection with the repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the Indenture, or compliance with the Asset Sale provisions of the Indenture would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under the Asset Sale provisions of the Indenture, as applicable, by virtue thereof.

The agreements governing the Company’s other indebtedness and future credit agreements or other agreements to which the Company becomes a party may limit or prohibit, the Company from purchasing any Notes as a result of an Asset Sale Offer. The exercise of Holders of the Notes of their right to require the Company to repurchase the Notes in connection with an Asset Sale Offer could cause a default under those other agreements. In the event the Company is required to make an Asset Sale Offer at a time when the Company is prohibited by the terms of any Indebtedness from purchasing the Notes, the Company could seek the consent of its lenders to permit the purchase of the Notes or could attempt to refinance the borrowings that contain such prohibition. If the Company does not obtain such consent or repay such borrowings, the Company will remain prohibited from purchasing the Notes. In such case, the Company’s failure to purchase tendered Notes would constitute an Event of Default under the Indenture that could, in turn, constitute a default under other indebtedness.

The provisions under the Indenture relative to the Company’s obligation to make an offer to repurchase the Notes as a result of an Asset Sale may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes.

For purposes of determining compliance with this “Restricted Payments” covenant, if a Restricted Payment meets the criteria of more than one of the categories of Restricted Payments described in the preceding clauses (1) through (9), the Company will be permitted to classify (or later classify or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that complies with this covenant.

Unrestricted Subsidiaries will not be subject to any of the restrictive covenants set forth in the Indenture.

For purposes of determining compliance with this covenant, in the event that an item of Indebtedness, Disqualified Stock or Preferred Stock meets the criteria of more than one of the categories of Permitted Debt described in clauses (a) through (u) above or is entitled to be incurred pursuant to the first paragraph of this covenant, the Company, in its sole discretion, will classify or reclassify or later divide, classify or reclassify such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) and will only be required to include the amount and type of such Indebtedness, Disqualified Stock or Preferred Stock in one or more of the above clauses.

The accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness, Disqualified Stock or Preferred Stock will not be deemed to be an incurrence of Indebtedness, Disqualified Stock or Preferred Stock for purposes of this covenant.

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency will be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term debt, or first committed, in the case of revolving credit debt; provided that if such Indebtedness is incurred to extend, replace, refund, refinance, renew or defease other Indebtedness denominated in a foreign currency, and such extension, replacement, refunding, refinancing, renewal or defeasance would cause the applicable U.S. dollar denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such extension, replacement, refunding, refinancing, renewal or defeasance such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased.

The principal amount of any Indebtedness incurred to extend, replace, refund, refinance, renew or defease other Indebtedness, if incurred in a different currency from the Indebtedness being extended, replaced, refunded, refinanced, renewed or defeased, shall be calculated based on the currency exchange rate applicable to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such extension, replacement, refunding, refinancing, renewal or defeasance.

The amount of any Indebtedness outstanding as of any date will be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) in the case of Hedging Obligations, the termination value of the agreement or arrangement giving rise to such obligations that would be payable by such Person at such time;

(3) the principal amount of the Indebtedness, in the case of any other Indebtedness; and

(4) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(a) the fair market value of such assets at the date of determination; and

(b) the amount of the Indebtedness of the other Person.

53

Liens

The Company will not, and will not permit any of the Subsidiary Guarantors to, directly or indirectly, create, incur, assume or suffer to exist any Lien (except Permitted Liens) that secures obligations under any Indebtedness on any asset or property of the Company or any Subsidiary Guarantor now owned or hereafter acquired, or any income or profits therefrom, or assign or convey any right to receive income therefrom, unless:

(1) in the case of Liens securing Subordinated Indebtedness, the Notes or the applicable Subsidiary Guarantee of a Subsidiary Guarantor, as the case may be, are secured by a Lien on such property or assets that is senior in priority to such Liens; and

(2) in all other cases, the Notes or the applicable Subsidiary Guarantee of a Subsidiary Guarantor, as the case may be, are equally and ratably secured;

providedthat any Lien that is granted to secure the Notes under this covenant shall be discharged at the same time as the discharge of the Lien that gave rise to the obligation to so secure the Notes.

Merger, Consolidation or Sale of All or Substantially All Assets

The Company may not consolidate or merge with or into or wind up into (whether or not the Company is the surviving entity), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets, in one or more related transactions, to any Person unless:

(1) the Company is the surviving company or the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, lease, conveyance or other disposition will have been made is a Person organized or existing under the laws of the United States of America, any state thereof, the District of Columbia, or any territory thereof (the Company or such Person, as the case may be, being herein called the “Successor Company”);provided that if such Person is not a corporation, such Person immediately causes a Subsidiary that is organized or existing as a corporation under the laws of the United States, any state of the United States or the District of Columbia to be added as a co-issuer of the Notes under the Indenture;

(2) the Successor Company, if other than the Company, expressly assumes all the obligations of the Company under the Indenture and the Notes pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee;

(3) immediately after such transaction, no Default exists;

(4) immediately after givingpro formaeffect to such transaction, as if such transaction had occurred at the beginning of the applicable four-quarter period,

(A) the Successor Company would be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first sentence of the covenant described under “—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock”; or

(B) the Fixed Charge Coverage Ratio for the Successor Company and the Restricted Subsidiaries on a consolidated basis would be greater than such ratio for the Company and the Restricted Subsidiaries immediately prior to such transaction;

providedthat compliance with this clause (4) shall not be required after the Notes have an Investment Grade Rating as specified under “—Covenant Termination”; and

(5) the Company shall have delivered to the Trustee an Officers’ Certificate and an opinion of counsel, each stating that such consolidation, merger or transfer and such supplemental indentures, if any, comply with the Indenture.

The Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and the Notes.

54

Notwithstanding the foregoing clauses (3) and (4),

(a) any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Company and

(b) the Company may merge with an Affiliate of the Company incorporated solely for the purpose of reincorporating the Company in another state of the United States of America or converting into a different form of business entity so long as the amount of Indebtedness of the Company and the Restricted Subsidiaries is not increased thereby.

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of the Company and its Subsidiaries on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties and assets of the Company.

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 Company will not, and will not permit any Restricted Subsidiary 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 of the Company (each of the foregoing, an “Affiliate Transaction”) involving aggregate payments or consideration in excess of $15.0 million, unless

(a) such Affiliate Transaction (taken as a whole, in the case of a series or group of related transactions, whether or not occurring substantially simultaneously) is on terms that are not materially less favorable to the Company 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, and

(b) the Company delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate payments or consideration in excess of $50.0 million, a Board Resolution adopted by the majority of the members of the Board of Directors of the Company approving such Affiliate Transaction and set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (a) above.

The following items will be deemed not to be Affiliate Transactions and, therefore, the foregoing provisions will not apply to the following:

(1) transactions between or among the Company and/or any of the Restricted Subsidiaries;

(2) (i) Restricted Payments permitted by the provisions of the Indenture described above under the covenant “—Limitation on Restricted Payments” and (ii) Permitted Investments;

(3) employment agreements, employee benefits plans, any indemnification agreement or any similar arrangement entered into and customary fees paid to, reimbursement of expenses paid to and indemnities provided on behalf of, officers, directors, managers, employees or consultants of the Company, any of its direct or indirect parent companies or any Restricted Subsidiary, in each case in the ordinary course of business;

(4) transactions in which the Company or any Restricted Subsidiary, as the case may be, delivers to the Trustee a letter from an Independent Financial Advisor stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or meets the requirements of clause (a) of the preceding paragraph;

55

(5) payments or loans (or cancellations of loans) to employees or consultants of the Company, any of its direct or indirect parent companies or any Restricted Subsidiary and employment agreements, stock option plans and other compensatory arrangements with such employees or consultants that are, in each case, approved by the Company in good faith and payments pursuant to the foregoing;

(6) any agreement, instrument or arrangement as in effect as of the Issue Date, or any amendment, modification or supplement thereto or replacement thereof (so long as any such amendment, modification, supplement or replacement is not disadvantageous to the Holders in any material respect as compared to the applicable agreement as in effect on the Issue Date as reasonably determined in good faith by the Company), and any transaction contemplated by any of the foregoing;

(7) the existence of, or the performance by the Company or any of the Restricted Subsidiaries of its obligations under the terms of, any stockholders agreement or its equivalent (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of the Issue Date and any similar agreements which it may enter into thereafter;provided,however, that the existence of, or the performance by the Company or any Restricted Subsidiary of obligations under any future amendment to any such existing agreement or under any similar agreement entered into after the Issue Date shall only be permitted by this clause (7) to the extent that the terms of any such existing agreement together with all amendments thereto, taken as a whole, or new agreement are not disadvantageous to the Holders in any material respect as compared to the terms of the original agreement as in effect on the Issue Date as reasonably determined in good faith by the Company;

(8) transactions with customers, clients, suppliers, or purchasers or sellers of goods or services, in each case in the ordinary course of business and otherwise in compliance with the terms of the Indenture that are fair to the Company and the Restricted Subsidiaries, in the reasonable determination of the Board of Directors or the senior management of the Company, or are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated party;

(9) the issuance of Equity Interests (other than Disqualified Stock) of the Company to any Affiliate of the Company or receipt by the Company of capital contributions from holders of its Equity Interests (other than Disqualified Stock);

(10) any Permitted MLP Transfer and any Permitted GP Transfer;

(11) leases entered into by the Company or any Restricted Subsidiary, as lessor and an Unrestricted Subsidiary, as lessee, with respect to a pipeline or similar asset operated by such Unrestricted Subsidiary;provided that the Remaining Present Value of any such leases shall not exceed $30.0 million in the aggregate;

(12) any agreement between any Person and an Affiliate of such Person existing at the time such Person is acquired by, merged into or amalgamated, arranged or consolidated with the Company or any of its Restricted Subsidiaries;provided that such agreement was not entered into in contemplation of such acquisition, merger, amalgamation, arrangement or consolidation, and any amendment, modification or supplement thereto, or replacement thereof (so long as any such amendment, modification, supplement or replacement is not more disadvantageous to the Holders in any material respect as compared to the applicable agreement as in effect on the date of such acquisition, merger, amalgamation, arrangement or consolidation) and any transaction contemplated by any of the foregoing;

(13) payment for services rendered between any MLP or GP and one or more of the Company or any of its Restricted Subsidiaries, if (x) payment is made or completed in compliance with the terms and provisions of the partnership agreement of the MLP (or comparable governing document of the GP) and (y) such transaction is on terms and conditions fair and reasonable to the Company or such Restricted Subsidiary as determined in good faith by the Company;

(14) transactions between the Company or any of its Restricted Subsidiaries and any Person that would not otherwise constitute an Affiliate Transaction except for the fact that one or more of the directors of such

56

other Person is also a director of the Company or such Restricted Subsidiary, as applicable; provided that such directors abstain from voting as a director of the Company or such Restricted Subsidiary, as applicable, on any matter involving such other Person; and

(15) in the case of contracts for the provision of gathering, treating or compression services with respect to Hydrocarbons or activities or services reasonably related thereto, or other operational contracts, any such contracts that are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Company or any of its Restricted Subsidiaries with unrelated third parties or otherwise on terms not materially less favorable to the Company and its Restricted Subsidiaries than those that would be available in a transaction with an unrelated third party.

Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries

The Company will not, and will not permit any Restricted Subsidiary that is not a Subsidiary Guarantor to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any such Restricted Subsidiary to:

(a) (1) pay dividends or make any other distributions to the Company or any Restricted Subsidiary on its Capital Stock or with respect to any other interest or participation in, or measured by, its profits, or

(2) pay any Indebtedness owed to the Company or any Restricted Subsidiary;

(b) make loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of, or a requirement to subordinate, loans or advances made to the Company or any Restricted Subsidiary to other Indebtedness incurred by the Company or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

(c) sell, lease or transfer any of its properties or assets to the Company or any Restricted Subsidiary, except (in each case) for such encumbrances or restrictions existing under or by reason of:

(1) contractual encumbrances or restrictions in effect on the Issue Date, including pursuant to the Existing Indentures, the Senior Credit Facility and the related documentation (including security documents and intercreditor agreements) and Hedging Obligations and contractual encumbrances or restrictions in agreements or instruments governing Credit Facilities not in effect on Issue Date so long as the encumbrances and restrictions contained therein are not materially more restrictive, taken as a whole, than the restrictions contained in those agreements on the Issue Date;

(2) the Indenture and the Notes and the Subsidiary Guarantees of the Notes issued thereunder;

(3) purchase money obligations for property acquired and Capitalized Lease Obligations that impose restrictions of the nature discussed in clause (c) above on the property so acquired and other Liens permitted to be incurred under the provisions of the covenant described above under “—Liens” that limit the right of the debtor to dispose of the assets subject to such Liens;

(4) applicable law or any applicable rule, regulation or order;

(5) any agreement or other instrument of a Person acquired by the Company or any Restricted Subsidiary in existence at the time of such acquisition (but not created in connection therewith or in contemplation thereof), 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 or as may be amended, restated, modified, renewed, extended, supplemented, refunded, replaced or refinanced from time to time (so long as the encumbrances and restrictions in any such amendment, restatement, modification, renewal, extension, supplement, refunding, replacement or refinancing are, in the good faith judgment of the board of directors of the Company, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition), which encumbrances 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 agreements or instruments governing Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred;

57

(6) contracts for the sale of assets, including customary restrictions with respect to a Subsidiary pursuant to an agreement that has been entered into for the sale or disposition of all or substantially all of the Capital Stock or assets of such Subsidiary;

(7) Secured Indebtedness otherwise permitted to be incurred pursuant to the covenants described under “—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock” and “—Liens” that limit the right of the debtor to dispose of the assets securing such Indebtedness;

(8) restrictions on cash or other deposits or net worth imposed by customers, suppliers or landlords or required by insurance, surety or bonding companies, in each case under contracts entered into in the ordinary course of business;

(9) other Indebtedness, Disqualified Stock or Preferred Stock of Restricted Subsidiaries permitted to be incurred after the Issue Date pursuant to the provisions of the covenant described under “—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock”;

(10) provisions in partnership and joint venture agreements, asset sale agreements, leases, licenses, sale-lease back agreements, stock sale agreements and other similar agreements;

(11) non-assignment provisions contained in leases, licenses and other agreements;

(12) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts distributions by such Restricted Subsidiary pending such sale or other disposition;

(13) restrictions or conditions contained in any trading, netting, operating, construction, service, supply, purchase, sale or other agreement to which the Company or any of its Restricted Subsidiaries is a party;providedthat such agreement prohibits the encumbrance of solely the property or assets of the Company or such Restricted Subsidiary that are the subject of such agreement, the payment rights arising thereunder and/or the proceeds thereof and does not extend to any other asset or property of the Company or such Restricted Subsidiary or the assets or property of any other Restricted Subsidiary;

(14) with respect to any Foreign Subsidiary, any encumbrance or restriction contained in the terms of any Indebtedness or any agreement pursuant to which such Indebtedness was incurred if either (a) the encumbrance or restriction applies only in the event of a payment default or a default with respect to a financial covenant in such Indebtedness or agreement or (b) the Company determines in good faith that any such encumbrance or restriction will not materially affect the Company’s ability to make principal or interest payments on the Notes; and

(15) any encumbrances or restrictions of the type referred to in clauses (a), (b) and (c) above imposed by any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations referred to in clauses (1) through (14) above;providedthat such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Company, not materially more restrictive with respect to such encumbrance and other restrictions than those prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing;provided,further, that with respect to contracts, instruments or obligations existing on the Issue Date, any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive with respect to such encumbrances and other restrictions than those contained in such contracts, instruments or obligations as in effect on the Issue Date.

Future Subsidiary Guarantors

The Company will cause each of its Wholly-Owned Subsidiaries that are Restricted Subsidiaries, other than a Subsidiary Guarantor, that becomes a borrower or guarantor under the Senior Credit Facility or guarantees, on

58

the Issue Date or any time thereafter, any other Indebtedness of the Company, which Indebtedness exceeds $25.0 million in aggregate principal amount, to, within 30 days:

(1) execute and deliver a supplemental indenture to the Indenture providing for a Subsidiary Guarantee by such Restricted Subsidiary, except that with respect to a guarantee of Indebtedness of the Company or any Subsidiary Guarantor that is by its express terms subordinated in right of payment to the Notes or such Subsidiary Guarantor’s Subsidiary Guarantee, any such guarantee by such Restricted Subsidiary with respect to such Indebtedness shall be subordinated in right of payment to such Subsidiary Guarantee substantially to the same extent as such Indebtedness is subordinated to the Notes;

(2) deliver to the Trustee an opinion of counsel to the effect that:

(a) such Subsidiary Guarantee has been duly executed and authorized; and

(b) such Subsidiary Guarantee constitutes a valid, binding and enforceable obligation of such Restricted Subsidiary, except insofar as enforcement thereof may be limited by bankruptcy, insolvency or similar laws (including, without limitation, all laws relating to fraudulent transfers) and except insofar as enforcement thereof is subject to general principles of equity.

Limitation on Sale and Lease-Back Transactions

The Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction with respect to any property unless (i) the Company or such Restricted Subsidiary would be entitled to (A) incur additional Indebtedness in an amount equal to the Attributable Debt with respect to such Sale and Lease-Back Transaction pursuant to the covenant described under “—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock” and (B) create a Lien on such property securing such Attributable Debt under the definition of “Permitted Liens” (providedthat compliance with clause (A) of this clause (i) shall not be required after such time that the Notes have an Investment Grade Rating as specified under “—Covenant Termination”); (ii) the consideration received by the Company or any Restricted Subsidiary in connection with such Sale and Lease-Back Transaction is at least equal to the fair market value (as determined in good faith by the Company) of such property; and (iii) the Company or such Restricted Subsidiary applies the proceeds of such transaction in compliance with the covenant described under “Repurchase at the Option of Holders—Asset Sales.”

Reports and Other Information

The Indenture provides that, notwithstanding that we may not be subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act or otherwise report on an annual and quarterly basis on forms provided for such annual and quarterly reporting pursuant to rules and regulations promulgated by the SEC, we will file with the SEC (and provide the Trustee and Holders with copies thereof, without cost to each Holder, within 15 days after we file them with the SEC):

(1) within the time period specified in the SEC’s rules and regulations, annual reports on Form 10-K (or any successor or comparable form) containing the information required to be contained therein (or required in such successor or comparable form);

(2) within the time period specified in the SEC’s rules and regulations, reports on Form 10-Q (or any successor or comparable form) containing the information required to be contained therein (or required in such successor or comparable form); and

(3) promptly from time to time after the occurrence of an event required to be therein reported (and in any event within the time period specified in the SEC’s rules and regulations), such other reports onForm 8-K (or any successor or comparable form);

provided,however, that (1) if we are not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, we may complete any such reports as though our only registered securities are non-convertible

59

debt securities and (2) we shall not be so obligated to file such reports with the SEC if the SEC does not permit such filing, in which event, we will make available such information to prospective purchasers of notes in addition to providing such information to the Trustee and the Holders, in each case within 15 days after the time we would be required to file such information with the SEC if we were subject to Section 13 or 15(d) of the Exchange Act.

Notwithstanding the foregoing, we will be deemed to have furnished such reports referred to above to the Trustee and Holders if we have filed such reports with the SEC via the EDGAR filing system (or any successor system) or, if we are not subject to reporting under Section 13 or 15(d) of the Exchange Act and are not permitted to file such reports with the SEC, if we post such reports on our publicly available website.

Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on officers’ certificates delivered under the Indenture).

Covenant Termination

If at any time the Notes have an Investment Grade Rating and no Default has occurred and is continuing under the Indenture, the Company and its Restricted Subsidiaries will not be subject to the provisions of the Indenture described above under “Repurchase at the Option of Holders—Asset Sales” and under the following headings under “Certain Covenants”:

• “—Limitation on Restricted Payments,”

• “—Limitation on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock,”

• clause (4) of the covenant described above under “—Merger, Consolidation or Sale of All or Substantially All Assets,”

• “—Transactions with Affiliates,”

• “—Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries” and

• “—Limitation on Sale and Lease-Back Transactions” (only to the extent set forth in such covenant)

providedthat the provisions of the Indenture described above under “Repurchase at the Option of Holders—Change of Control Triggering Event,” “Reports and Other Information” and described above under the following headings under “Certain Covenants” will not be terminated:

• “—Liens,”

• “—Merger, Consolidation or Sale of All or Substantially All Assets” (except with respect to clause (4) of such covenant),

• “—Future Subsidiary Guarantors,” and

• “—Limitation on Sale and Lease-Back Transactions” (except to the extent set forth in such covenant).

Events of Default and Remedies

The following events constitute Events of Default under the Indenture:

(1) default in payment when due and payable, upon redemption, acceleration or otherwise, of payments of principal of, or premium, if any, on the Notes issued under the Indenture;

(2) default for 30 days or more in the payment when due of interest on or with respect to the Notes issued under the Indenture;

60

(3) failure by the Company for 180 days after receipt of written notice given by the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding and issued under the Indenture voting as a single class to comply with the provisions described under “Reports and Other Information”;

(4) failure by the Company for 60 days after receipt of written notice given by the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding and issued under the Indenture voting as a single class to comply with any of the other agreements in the Indenture or the Notes;

(5) failure by the Company to make a Change of Control Offer or an Asset Sale Offer within the time periods set forth, or to consummate a purchase of Notes when required pursuant to the terms described, under “Repurchase at the Option of Holders��Change of Control Triggering Event” or “Repurchase at the Option of Holders—Asset Sales” or to comply with the provisions described under “Certain Covenants—Merger, Consolidation or Sale of All or Substantially All Assets”;

(6) default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness for money borrowed by the Company or any Restricted Subsidiary or the payment of which is guaranteed by the Company or any Restricted Subsidiary, other than Indebtedness owed to the Company or a Restricted Subsidiary, whether such Indebtedness or guarantee now exists or is created after the issuance of the Notes, if both

(A) such default either

(i) results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods) or

(ii) relates to an obligation other than the obligation to pay principal of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to its stated maturity and

(B) the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so accelerated, aggregate $75.0 million or more at any one time outstanding;

(7) failure by the Company or any Restricted Subsidiary that is a Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary) to pay final judgments aggregating in excess of $75.0 million, which final judgments remain unpaid, undischarged and unstayed for a period of more than 60 days after such judgment becomes final, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed;

(8) certain events of bankruptcy or insolvency with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Significant Subsidiary); or

(9) the Subsidiary Guarantee of any Significant Subsidiary (or any group of Subsidiaries that together would constitute a Significant Subsidiary) shall for any reason cease to be in full force and effect or be declared null and void or any responsible officer of any Subsidiary Guarantor that is a Significant Subsidiary (or the responsible officers of any group of Subsidiaries that together would constitute a Significant Subsidiary), as the case may be, denies that it has any further liability under its Subsidiary Guarantee or gives notice to such effect, other than by reason of the termination of the Indenture or the release of any such Subsidiary Guarantee in accordance with the Indenture.

If any Event of Default (other than of a type specified in clause (8) above) occurs and is continuing under the Indenture, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes issued under the Indenture may declare the principal, premium, if any, interest and any other monetary obligations on all the then outstanding Notes issued under the Indenture to be due and payable immediately.

61

Upon the effectiveness of such declaration, such principal of and premium, if any, and interest on the Notes will be due and payable immediately. Notwithstanding the foregoing, in the case of an Event of Default arising under clause (8) of the first paragraph of this section with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary (or any group of Restricted Subsidiaries that together would constitute a Restricted Subsidiary), all outstanding Notes will become due and payable without further action or notice. The Indenture provides that the Trustee may withhold from Holders notice of any continuing Default, except a Default relating to the payment of principal of and premium, if any, and interest on the Notes if it determines that withholding notice is in their interest. In addition, the Trustee will have no obligation to accelerate the Notes if in the judgment of the Trustee acceleration is not in the interest of the Holders of such Notes.

The Indenture provides that the Holders of a majority in aggregate principal amount of the then outstanding Notes issued thereunder by notice to the Trustee may, on behalf of the Holders of all of such Notes, rescind an acceleration, waive any existing Default or Event of Default and its consequences under the Indenture, except a continuing Default in the payment of principal of and premium, if any, or interest on any such Notes held by a non-consenting Holder. In the event of any Event of Default specified in clause (6) above, such Event of Default and all consequences thereof (excluding any resulting payment default) shall be annulled, waived and rescinded automatically and without any action by the Trustee or the Holders if, within 20 days after such Event of Default arose,

(x) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged,

(y) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or

(z) if the default that is the basis for such Event of Default has been cured.

Except to enforce the right to receive payments of principal of and premium, if any, and interest on the Notes when due, no Holder may pursue any remedy with respect to the Indenture or the Notes unless:

(1) such Holder has previously given the Trustee notice that an Event of Default is continuing;

(2) Holders of at least 25% in principal amount of the outstanding Notes have requested the Trustee to pursue the remedy;

(3) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

(4) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and

(5) Holders of a majority in principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

The Indenture provides that we are required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and we are required upon any officer of the Company becoming aware of any Default, the Company is required to deliver to the Trustee a statement specifying such Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator or stockholder of the Company or any Subsidiary Guarantor shall have any liability for any obligations of the Company or the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees and the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation;provided that the foregoing shall not limit any Subsidiary Guarantor’s obligations under its Subsidiary Guarantee. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the Federal securities laws and it is the view of the SEC that such a waiver is against public policy.

62

Legal Defeasance and Covenant Defeasance

The Company may, at its option and at any time, elect to have all of its obligations discharged with respect to the Notes issued under the Indenture and have each Subsidiary Guarantor’s obligation discharged with respect to its Subsidiary Guarantee (“Legal Defeasance”) and cure all then existing Events of Default except for

(1) the rights of Holders issued under the Indenture to receive payments in respect of the principal of, premium, if any, and interest on the Notes when such payments are due solely out of the trust created pursuant to the Indenture,

(2) the Company’s obligations with respect to the Notes issued under the Indenture concerning issuing temporary Notes, registration of such 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 Company’s obligations in connection therewith and

(4) the Legal Defeasance provisions of the Indenture.

In addition, the Company may, at its option and at any time, elect to have its obligations and those of each Subsidiary Guarantor released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Notes. In the event a Covenant Defeasance occurs, certain events (not including bankruptcy, receivership, rehabilitation and insolvency events pertaining to the Company) described under “Events of Default and Remedies” will no longer constitute an Event of Default with respect to the Notes.

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to the Notes issued under the Indenture:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest due on the Notes issued under the Indenture on the stated maturity date or on the applicable redemption date, as the case may be, of such principal, premium, if any, or interest on the Notes;

(2) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States of America reasonably acceptable to the Trustee confirming that, subject to customary assumptions and exclusions,

BOOK-ENTRY; DELIVERY AND FORM

Global Notes

The New Notes, like the Old Notes, will be issued in the form of one or more fully registered notes in global form, without interest coupons. The New Notes will be deposited with the Trustee, as custodian for The Depository Trust Company (“DTC”), and registered in the name of Cede & Co., as nominee of DTC.

Ownership of beneficial interests in each global note will be limited to persons who have accounts with DTC (“DTC participants”) or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

• on deposit of each global note with DTC’s custodian, DTC will credit portions of the principal amount of the global notes to the accounts of the DTC participants that have tendered the Old Notes to the account designated by the exchange agent; and

• ownership of beneficial interests in each global note will be shown on, and transfer of ownership of those interests will be effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the global notes).

Beneficial interests in the global notes may not be exchanged for notes in physical, certificated form except in the limited circumstances described below.

Book-Entry Procedures for the Global Notes

All interests in the global notes will be subject to the operations and procedures of DTC, including its participants, Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), and Clearstream Banking S.A. (“Clearstream”). We provide the following summaries of those operations and procedures solely for the convenience of investors. The operations and procedures of each settlement system are controlled by that settlement system and may be changed at any time.

• Neither we nor the Trustee is responsible for those operations or procedures.

• DTC has advised us that it is:

• a limited purpose trust company organized under the laws of the State of New York;

• a “banking organization” within the meaning of the New York State Banking Law;

• a member of the Federal Reserve System;

• a “clearing corporation” within the meaning of the Uniform Commercial Code; and

• a “clearing agency” registered under Section 17A of the Exchange Act.

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC’s participants include securities brokers and dealers, banks and trust companies, clearing corporations, and other organizations. Indirect access to DTC’s system is also available to others such as banks, brokers, dealers, and trust companies. These indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC’s nominee is the registered owner of a global note, that nominee will be considered the sole owner or holder of the Notes represented by that global note for all purposes under the Indenture. Except as provided below, owners of beneficial interests in a global note:

• will not be entitled to have Notes represented by the global note registered in their names;

92

• will not receive or be entitled to receive physical, certificated Notes; and

• will not be considered the owners or holders of the Notes under the Indenture for any purpose, including with respect to the giving of any direction, instruction, or approval to the Trustee.

As a result, each investor who owns a beneficial interest in a global note must rely on the procedures of DTC to exercise any rights of a holder of Notes under the Indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

Payments of principal, premium (if any), and interest with respect to the New Notes represented by a global note will be made by the Trustee to DTC’s nominee, as the registered holder of the global note. Neither we nor the Trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global note, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising, or reviewing any records of DTC relating to those interests.

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC.

Transfers between participants in DTC will be effected under DTC’s procedures and will be settled in same-day funds. Transfers between participants in Euroclear or Clearstream will be effected in the ordinary way under the rules and operating procedures of those systems.

Cross market transfers between DTC participants, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected within DTC through the DTC participants that are acting as depositaries for Euroclear and Clearstream. To deliver or receive an interest in a global note held in a Euroclear or Clearstream account, an investor must send transfer instructions to Euroclear or Clearstream, as the case may be, under the rules and procedures of that system and within the established deadlines of that system. If the transaction meets its settlement requirements, Euroclear or Clearstream, as the case may be, will send instructions to its DTC depositary to take action to effect final settlement by delivering or receiving interests in the relevant global notes in DTC, and making or receiving payment under normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the DTC depositaries that are acting for Euroclear or Clearstream.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant that purchases an interest in a global note from a DTC participant will be credited on the business day for Euroclear or Clearstream immediately following the DTC settlement date. Cash received in Euroclear or Clearstream from the sale of an interest in a global note to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Euroclear or Clearstream cash account as of the business day for Euroclear or Clearstream following the DTC settlement date.

DTC, Euroclear, and Clearstream have agreed to the above procedures to facilitate transfers of interests in the global notes among participants in those settlement systems. However, the settlement systems are not obligated to perform these procedures and may discontinue or change these procedures at any time. Neither we nor the Trustee will have any responsibility for the performance by DTC, Euroclear, or Clearstream, or their participants or indirect participants, of their obligations under the rules and procedures governing their operations.

93

Certificated Notes

New Notes in physical, certificated form (“Certificated Securities”) will be issued and delivered to each person that DTC identifies as a beneficial owner of the related Notes only if:

• DTC notifies us at any time that it is unwilling or unable to continue as depositary for the global notes and a successor depositary is not appointed within 90 days;

• DTC ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days;

• there shall have occurred and be continuing an event of default with respect to the Notes under the Indenture and DTC shall have requested the issuance of Certificated Securities; or

• we, at our option notify the Trustee that we elect to cause the issuance of certificated Notes.

94

PLAN OF DISTRIBUTION

You may transfer New Notes issued under the exchange offer in exchange for the Old Notes if:

• you acquire the New Notes in the ordinary course of your business;

• you have no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the New Notes in violation of the provisions of the Securities Act; and

• you are not our “affiliate” (within the meaning of Rule 405 under the Securities Act).

Each broker-dealer that receives New Notes for its own account under the exchange offer in exchange for Old Notes that were acquired by that broker-dealer as a result of market-making or other trading activities must acknowledge that it will deliver a prospectus in connection with any resale of those New Notes. 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 the Old Notes were acquired as a result of market-making activities or other trading activities.

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—Purpose and Effect of the Exchange Offer” and “—Procedures for Tendering—Your Representations to Us” in this prospectus and in the letter of transmittal. 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 that you will deliver a prospectus in connection with any resale by you of those 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 under the exchange offer may be sold from time to time in one or more transactions in any of the following ways:

• in the over-the-counter market;

• in negotiated transactions;

• through the writing of options on the New Notes or a combination of these methods of resale;

• at market prices prevailing at the time of resale;

• at prices related to the prevailing market prices; or

• at negotiated prices.

Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such New Notes.

Any broker-dealer that resells New Notes that were received by it for its own account under the exchange offer in exchange for Old Notes that were acquired by such broker-dealer as a result of market-making or other trading activities may be deemed to be an “underwriter” within the meaning of the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. We agreed to permit the use of this prospectus for a period of up to 180 days after the expiration date of the exchange offer to satisfy this prospectus delivery requirement. Furthermore, we agreed to amend or supplement this prospectus during that period if so requested in order to expedite or facilitate the disposition of any New Notes by broker-dealers.

We have agreed to pay all expenses incident to the exchange offer other than fees and expenses of counsel to the holders and brokerage commissions and transfer taxes, if any, and will indemnify the holders of the Old Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

MATERIAL UNITED STATES FEDERAL TAX CONSEQUENCES

The following discussion is a summary of the material federal income tax considerations relevant to the exchange of Old Notes for New Notes, but does not purport to be a complete analysis of all potential tax effects. The discussion is based on the Internal Revenue Code of 1986, as amended, Treasury Regulations, Internal Revenue Service rulings and pronouncements and judicial decisions now in effect, all of which may be subject to change at any time by legislative, judicial or administrative action. These changes may be applied retroactively in a manner that could adversely affect a holder of New Notes. Some holders, including financial institutions, insurance companies, regulated investment companies, tax-exempt organizations, dealers in securities or currencies, persons whose functional currency is not the U.S. dollar, or persons who hold the Notes as part of a hedge, conversion transaction, straddle or other risk reduction transaction may be subject to special rules not discussed below. We recommend that each holder consult his own tax advisor as to the particular tax consequences of exchanging that holder’s Old Notes for New Notes, including the applicability and effect of any foreign, state, local or other tax laws or estate or gift tax considerations.

We believe that the exchange of Old Notes for New Notes will not be an exchange or otherwise a taxable event to a holder for United States federal income tax purposes. Accordingly, a holder will not recognize gain or loss on receipt of a New Note in exchange for an Old Note in the exchange, and the holder’s basis and holding period in the New Note will be the same as its basis and holding period in the corresponding Old Note immediately before the exchange.

If you wish to exchange your issued and outstanding 6.375% Senior Notes due 2025 (“Old Notes”) for an equal aggregate principal amount of newly issued 6.375% Senior Notes due 2025 (“New Notes”) with materially identical terms that have been registered under the Securities Act of 1933, as amended (the “Securities Act”), under the exchange offer, you must validly tender (and not withdraw) your Old Notes to the Exchange Agent before the Expiration Date.

We refer you to the Prospectus, dated                 , 2018 (the “Prospectus”), of SemGroup Corporation (the “Issuer”), and this Letter of Transmittal (the “Letter of Transmittal”), which together describe the Issuer’s offer (the “Exchange Offer”) to exchange the Old Notes for a like aggregate principal amount of New Notes. Capitalized terms used but not defined herein have the respective meaning given to them in the Prospectus.

The Issuer reserves the right, at any time or from time to time, to extend the Exchange Offer at its discretion, in which event the term “Expiration Date” shall mean the latest date to which the Exchange Offer is extended. The Issuer shall notify the Exchange Agent and each registered holder of the Old Notes of any extension by oral (promptly followed in writing) or written notice before 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. Tender of Old Notes is to be made according to the Automated Tender Offer Program (“ATOP”) of The Depository Trust Company (“DTC”) under the procedures set forth in the Prospectus under the caption “Exchange Offer—Procedures for Tendering.” 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, before 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.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

SemGroup Corporation and Rose Rock Finance Corporation

Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”) grants us the authority to indemnify each of our directors and officers against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by a director or officer that is made a party to any threatened, pending or completed action, suit or proceeding (whether civil, criminal or otherwise), by reason of the fact that such director or officer is or was a director, officer, employee or agent of ours or by reason of the fact that such director or officer, at our request, is or was serving at any other corporation or other entity, in any capacity, if such director or officer acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful; provided, that in the case of an action, suit or proceeding against a director or officer that is brought by us or in our right, we may indemnify such director or officer only in respect of expenses (including attorneys’ fees) actually and reasonably incurred by such director or officer; provided further, that no such indemnity for expenses may be made with respect to any claim, issue or matter as to which such director or officer shall have been adjudged to be liable to us unless, and only to the extent that, either the Delaware Court of Chancery or the court in which the action, suit or proceeding against such director or officer was brought shall determine upon application that, despite the adjudication of liability to us but in view of all the circumstances of the case, such director or officer is nevertheless fairly and reasonably entitled to indemnity from us for such expenses in an amount deemed proper by such court.

Unless ordered by a court, the determination of whether a then sitting director or officer has met the applicable standard for indemnity, i.e., that the director or officer acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful, shall be made (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by our stockholders.

Section 145 of the DGCL also authorizes us to advance expenses (including attorneys’ fees) incurred by a director or officer in defending any action, suit or proceeding against the director or officer prior to a determination of whether the director or officer is actually entitled to indemnity and to purchase insurance for the benefit of a director or officer against any liability that may be incurred by reason of the fact that the insured was or is a director or officer, regardless of whether the liability insured could have legally been indemnified by us.

Pursuant to the authority granted us by Section 145 of the DGCL, we have provided in the amended and restated certificate of incorporation and amended and restated bylaws of SemGroup Corporation for the indemnification of and advancement of expenses to our directors to the fullest extent authorized or permitted by law as from time to time in effect; provided, however, we are required to indemnify, or advance expenses to, any such director in connection with an action, suit, claim or proceeding initiated by such director only if the initiation of such action, suit, claim or proceeding has been authorized or ratified by our Board of Directors. Our amended and restated bylaws provide that we may, to the extent authorized by our Board of Directors, grant rights of indemnification and the advancement of expenses (including attorney’s fees) to our officers. Our Board of Directors has authorized indemnification of, and advancement of expenses to, our officers serving as such on or after December 1, 2009. The rights authorized by our Board of Directors for the indemnification of, and advancement of expenses to, our officers serving as such on or after December 1, 2009 are the same rights that have been afforded our directors pursuant to our amended and restated certificate of incorporation and amended and restated bylaws.

II-1

Pursuant to the authority granted to us by Section 145 of the DGCL, we have provided in the certificate of incorporation and bylaws for Rose Rock Finance Corporation for the indemnification of and advancement of expenses to our directors and officers to the fullest extent authorized or permitted by law as from time to time in effect.

The employment agreement among us, SemManagement, L.L.C., Rose Rock Midstream GP, LLC and Carlin G. Conner, our President and Chief Executive Officer, provides Mr. Conner with indemnification and advancement of expenses (including attorney’s fees) to the maximum extent permitted by the amended and restated certificate of incorporation and amended and restated bylaws of SemGroup Corporation, including, if applicable, any directors and officers insurance policies, provided such indemnification shall be on terms no less favorable than provided to any of our other executive officers or directors. Pursuant to the employment agreement, we have also agreed to maintain commercially reasonable directors’ and officers’ insurance covering Mr. Conner in such amount and pursuant to such terms as is typical and customary for companies of similar size and nature to us.

We have also purchased a policy of insurance for the benefit of our directors and officers that provides standard liability coverage.

As permitted by Section 102 of the DGCL, the amended and restated certificate of incorporation for SemGroup Corporation and the certificate of incorporation for Rose Rock Finance Corporation provide that each of our directors shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director; provided, that a director shall be liable for any breach of such director’s duty of loyalty to the corporation or its stockholders, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, for liability under Section 174 of the DGCL (involving certain unlawful dividends or stock repurchases), or for any transaction from which such director derived an improper personal benefit.

Item 22. Undertakings.

Each registrant hereby undertakes:

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(a) to include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(b) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(c) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-9

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if such registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

That, for the purpose of determining liability of such registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, in a primary offering of securities of such registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrants will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(a) any preliminary prospectus or prospectus of the undersigned registrants relating to the offering required to be filed pursuant to Rule 424;

(b) any free writing prospectus relating to the offering prepared by or on behalf of such registrant or used or referred to by the undersigned registrants;

(c) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrants or their securities provided by or on behalf of such registrant; and

(d) any other communication that is an offer in the offering made by such registrant to the purchaser.

That, for purposes of determining any liability under the Securities Act of 1933, each filing of a registrant annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrants of expenses incurred or paid by a director, officer or controlling person of a registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, such registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of FormS-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

II-10

To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

II-11
