Cautionary Note Regarding Forward-Looking Statements

Certain matters contained in this Form 10-K include forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933, as amended (the Securities Act), and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). We make these forward-looking statements in reliance on the safe harbor
protections provided under the Private Securities Litigation Reform Act of 1995.

All statements, other than statements of
historical fact, included in this Form 10-K regarding the prospects of our industry, our anticipated financial performance, the anticipated performance of NGL Energy Partners LP, managements plans and objectives for future operations, business
prospects, outcome of regulatory proceedings, market conditions, and other matters, may constitute forward-looking statements. In addition, forward-looking statements generally can be identified by the use of forward-looking words such as
may, will, expect, intend, estimate, foresee, project, anticipate, believe, plans, forecasts, continue or
could or the negative of these terms or variations of them or similar terms. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we cannot assure you that these expectations will prove
to be correct. These forward-looking statements are subject to certain known and unknown risks, and uncertainties, as well as assumptions that could cause actual results to differ materially from those reflected in these forward-looking statements.
Factors that might cause actual results to differ include, but are not limited to, those discussed in Item 1A of this Form 10-K, entitled Risk Factors, risk factors discussed in other reports that we file with the Securities and
Exchange Commission (SEC), and the following:



| |  |  | Our ability to generate sufficient cash flow from operations to enable us to pay our debt obligations or to fund our other liquidity needs;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our ability to comply with the covenants contained in, and maintain certain financial ratios required by, our credit facilities;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our ability to obtain additional capital on terms that are favorable to us;
| | - |  | ---------------------------------------------------------------------------



| |  |  | The ability of our subsidiary, Rose Rock Midstream, L.P., to make minimum quarterly distributions to its unitholders, including us;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | The operations of NGL Energy Partners LP, which we do not control;
| | - |  | ------------------------------------------------------------------



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



| |  |  | Any sustained reduction in demand for the petroleum products we gather, transport, process, and store;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | Our ability to obtain new sources of supply of petroleum products;
| | - |  | ------------------------------------------------------------------



| |  |  | Our failure to comply with new or existing environmental laws or regulations or cross border laws or regulations;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | The possibility that the construction or acquisition of new assets may not result in the corresponding anticipated revenue increases;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The effects of having recently filed for and emerged from bankruptcy protection;
| | - |  | --------------------------------------------------------------------------------



| |  |  | Any future impairment to goodwill resulting from the loss of customers or business;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | Changes in currency exchange rates; and
| | - |  | ---------------------------------------



| |  |  | The risks and uncertainties of doing business outside of the U.S., including political and economic instability and changes in local governmental laws,
regulations and policies.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

New factors that could cause actual results to differ materially from those
described in forward-looking statements emerge from time to time, and it is not possible for us to predict all such factors, or the extent to which any such factor or combination of factors may cause actual results to differ from those contained in
any forward-looking statement.

Our History

SemGroup
Corporation is a Delaware corporation. We were founded in February 2000 and are based in Tulsa, Oklahoma. During the period from February 2000 through July 2008, our asset and revenue base grew through a series of strategic acquisitions and capital
expansion projects. During this time period, we made 64 acquisitions at an aggregate purchase price of approximately $1.1 billion, excluding amounts paid for working capital, and spent approximately $732 million on capital expansion projects.

Historically, we conducted significant physical and financial marketing and trading activities to take advantage of price
differences related to time, location and quality of various energy commodity products and to utilize our transportation and storage assets. We also provided midstream energy related services such as gathering, storage, transportation, processing
and distribution of petroleum products, both to third party customers and to ourselves.

As a result of trading losses
incurred and other negative economic conditions, we faced a liquidity crisis and on July 22, 2008, we filed voluntary petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code, as well as applications for creditor protection
under the Companies Creditors Arrangement Act in Canada (collectively, the Bankruptcy). During the Bankruptcy, we continued to operate our midstream energy-related businesses, exited certain non-core businesses and activities,
disposed of certain assets and continued certain energy infrastructure construction projects. Certain of our business units also continued marketing activities to fulfill contractual obligations and to utilize their asset bases.

During the Bankruptcy, we took steps to restructure our business portfolio and to rebalance to a business heavily weighted toward
fee-based asset activities and away from trading activities. As part of these steps, and

subject to the terms of our debtor in possession credit facility, we attempted to sell certain assets. Due to the economic environment and a lack of available financing, bids for various assets
came in below valuation expectations. In some cases, assets were not sold for strategic reasons. However, the assets of two business units, SemFuel and SemMaterials, were sold in a series of transactions during the divestiture process. For
additional information relating to our recent divestitures, refer to Notes 6 and 7 of our consolidated financial statements beginning on page F-1 of this Form 10-K. Additionally, we ceased the operations of two other businesses, SemCanada Energy and
SemEuro Supply. Also during the Bankruptcy, certain creditors foreclosed on our ownership interests in SemGroup Energy Partners G.P., L.L.C., the general partner of Blueknight Energy Partners, L.P., formerly known as SemGroup Energy Partners, L.P.
(Blueknight), and also on our subordinated units in Blueknight. As a result, we no longer had, and we no longer have, any direct or indirect ownership interest in Blueknight.

On November 30, 2009, we emerged from the Bankruptcy as a newly reorganized company. We continue to provide midstream energy
services in North America and the U.K. from an asset base consisting of pipelines, gathering systems, storage facilities, terminals, processing plants and other distribution assets. Midstream services are provided to independent producers, refiners
of petroleum products and other market participants. We also selectively engage in marketing activities geared toward serving our customers and maximizing the value of our asset base.

As part of the reorganization, and in conjunction with approval from our creditors and the U.S. Bankruptcy Court, we appointed a new
Board of Directors and senior management team. Norman Szydlowski was hired as Chief Executive Officer and brings considerable industry experience, management and leadership skills. Additionally, Robert Fitzgerald was hired as Senior Vice President
and Chief Financial Officer and Candice Cheeseman was hired as General Counsel.

We conduct our operations
through six primary business segments: Crude, SemStream®, SemLogistics, SemCAMS, SemMexico and SemGas®. The following diagram is a simplified organizational chart of our business segments:

We previously had a seventh business segment, SemCanada Crude, which aggregated and blended crude oil
in Western Canada. Due to adverse market conditions impacting this segment, we sold the property, plant and equipment of SemCanada Crude in late 2010 and began winding down its operations.

On November 1, 2011, we contributed the primary operating assets of our SemStream
segment to NGL Energy Partners LP in exchange for cash and equity interests. We retained our ownership interest in SemStreams Arizona residential business. (See Item 7. Managements Discussion and Analysis of Financial Condition and
Results of Operations for additional information.)

Rose Rock Midstream, L.P. (Rose Rock) was formed in August
2011. On November 29, 2011, SemGroup Corporation contributed a wholly-owned subsidiary, SemCrude, L.P., to Rose Rock, in return for limited partner interests, general partner interests, and certain incentive distribution rights in Rose Rock. On
December 14, 2011, Rose Rock completed an initial public offering (IPO) in which it sold 7,000,000 common units representing limited partner interests. Based on our control of, and ownership interest in, Rose Rock, we continue to
consolidate Rose Rock and account for other partnership interest in Rose Rock as non-controlling interest.

We previously
referred to the crude business segment as SemCrude, but following the contribution of SemCrude, L.P. to Rose Rock, we decided to change the name of the segment to Crude. The Crude business segment holds a 51% ownership interest in White
Cliffs Pipeline L.L.C. and a 2% general partner interest and a 57.0% limited partner interest in Rose Rock.

Industry Overview

We move petroleum products throughout the U.S., Canada, Mexico and the U.K. We provide gathering, transportation, storage,
distribution, marketing and other midstream services to producers and refiners of petroleum products. The market we serve, which begins at the point of purchase at the source of production and extends to the point of distribution to the end-user
customer, is commonly referred to as the midstream market.

Regional Production of Petroleum Products in the U.S.

The U.S. Department of Energy divides the continental U.S. into five geographic regions called Petroleum Administration
for Defense Districts, or PADDs. PADD 2 is the Midwest region of the U.S. PADD 2 is the second largest PADD in terms of refinery production, surpassed only by PADD 3. As a result of the flow of petroleum products across and throughout
the Midwest region, we believe PADD 2 is an important crude oil production, logistics and refining center.



LOGO

According to Energy Information Administration (EIA) data, as of November 2011,
approximately 21%, or 3.7 million barrels per day (Bpd), of total U.S. daily refining capacity was in PADD 2. Also, according to November 2011 EIA reports, PADD 2 produces approximately 14%, or 0.8 million Bpd, of total U.S.
daily crude oil production and imports approximately 13.6%, or 1.7 million Bpd, of total U.S. daily imports.

##### Table of Contents

PADD 2 refiners source crude oil from the Gulf Coast, Rocky Mountain, Canadas Western
Canadian Sedimentary Basin, which includes Alberta and parts of Saskatchewan to the East and British Columbia to the West, and major commodity hubs in the U.S. The production of petroleum products by PADD 2 refiners and processors historically has
been less than the demand for petroleum products within that region, with the shortfall being supplied via common carrier pipelines primarily from the Gulf Coast, Canada and, to a lesser extent, the Rocky Mountain and East Coast regions. Additional
petroleum product supply is available via barge transport up the Mississippi River with significant deliveries into local markets along the Ohio River.

Increased Importance of Independents and Specialization

In the 1990s, the
major oil companies began focusing primarily on large-scale oil and gas projects. Until recently, this resulted in the major oil companies focusing more on foreign and deep-water exploration and production activities. As a result, they
sold many of their North American integrated oil and gas assets, including producing properties, proprietary transportation systems, storage and distribution networks and refineries to independent operators. Whereas the major oil companies typically
owned and operated proprietary networks that handled every aspect of the production, refining, storage, transportation and marketing of petroleum products, independent operators have generally focused on a single activity. As a result, the North
American market is increasingly characterized by independent oil and gas producers and refiners that are generally without their own gathering, transportation, storage and distribution infrastructure. We focus on providing these services, using our
asset base and distribution, processing and marketing expertise to provide independent operators with a stable source of supply and market access for their petroleum products.

Crude Oil Industry Overview

Refined petroleum products, such as jet fuel,
gasoline and distillate fuel oil, are all sources of energy derived from crude oil. According to 2010 data compiled by the EIA, petroleum currently accounts for about 44% of the nations total annual energy consumption. Growth in petroleum
consumption is expected to keep pace with growth in overall energy consumption over the next 20 to 25 years. The EIA expects U.S. annual petroleum consumption to grow 13.5% from 17.1 million barrels per day in 2009 to 19.4 million barrels
per day in 2035. The diagram below depicts the segments of the crude oil value chain and our participation in the crude oil industry.

##### Table of Contents

Our crude oil business operates primarily in Colorado, Kansas, North Dakota, Oklahoma and
Texas where there are extensive crude oil production operations. Our assets extend from gathering systems in and around producing fields to transportation pipelines carrying crude oil to logistics hubs, such as the Cushing Interchange, where we have
terminalling and storage facilities that aid our customers in managing the delivery of crude oil.

Gathering and Transportation

Pipeline transportation is generally the lowest cost method for shipping crude oil and transports about two-thirds of
the petroleum shipped in the U.S. Crude oil pipelines transport oil from the wellhead to logistics hubs and/or refineries. Crude oil gathering assets generally consist of a network of smaller diameter pipelines that are connected directly to the
well site or central receipt points delivering into larger diameter trunk lines. Logistic hubs like the Cushing Interchange provide storage and connections to other pipeline systems and modes of transportation, such as tankers, railroads and trucks.
Trucking complements pipeline gathering systems by gathering crude oil from operators at remote wellhead locations not served by pipeline gathering systems. Trucking is generally limited to low volume, short haul movements because trucking costs
escalate sharply with distance, making trucking the most expensive mode of crude oil transportation.

Storage Terminals and Supply

Storage terminals complement the crude oil pipeline gathering and transportation systems and address a fundamental
imbalance in the energy industry wherein crude oil is often produced in different locations and at different times than it is ultimately consumed. Within the U.S., there are also geographical imbalances, as a substantial majority of the petroleum
refining that occurs in the U.S. east of the Rocky Mountains is concentrated in the Gulf Coast region, particularly Louisiana and Texas which, according to the EIA, accounts for approximately 48% of all refining capacity in the United States. Over
time, the crude oil storage business has evolved from its beginnings as a component of integrated production processes into a mature, stand-alone operation.

Terminals are facilities in which crude oil is transferred to or from a storage facility or transportation system, such as a gathering pipeline, to another transportation system, such as trucks or another
pipeline. Terminals play a key role in moving crude oil to end-users, such as refineries, by providing the following services:



| |  |  | inventory management;
| | - |  | ---------------------



| |  |  | distribution; and
| | - |  | -----------------



| |  |  | upgrading to achieve marketable grades or qualities of crude oil.
| | - |  | -----------------------------------------------------------------

Overview of Cushing Interchange

The Cushing Interchange is one of
the largest crude oil marketing hubs in the U.S. and is the designated point of delivery specified in all NYMEX crude oil futures contracts. As the NYMEX delivery point and a cash market hub, the Cushing Interchange serves as a significant source of
refinery feedstock for Midwest refiners and plays an integral role in establishing and maintaining markets for many varieties of foreign and domestic crude oil.

Natural Gas Industry Overview

In 2010, according to EIA data, natural gas
was the second largest source of primary energy, accounting for 30% of total U.S. energy use in 2010. While the primary use for natural gas in the U.S. is for residential heating, it also has a number of commercial, industrial and electric
generation uses across several different customer bases. The EIA forecasts that natural gas consumption will increase from 23.3 quadrillion BTU in 2009 to 27.24 quadrillion BTU in 2035.

##### Table of Contents

Since mid-2008, North American natural gas prices have declined significantly as a result of
drilling technology improvements and the recent development of shale. Demand for natural gas and NGLs has historically been higher during the winter and lower during the summer, as gas is used primarily for heating and the need for it increases in
cold months.

Natural gas passes through many stages before reaching end-users. First, exploration and production companies
locate and produce natural gas. Second, gathering companies collect the natural gas, sometimes sending it to processing plants where liquids and other elements are removed. Third, transmission companies transport the gas through pipelines to storage
units or areas of high demand. Finally, distributors deliver the gas to customers. The midstream natural gas industry is the link between upstream exploration and production activities and downstream end-use markets. The diagram below depicts the
segments of the natural gas value chain and our participation in the natural gas industry.



LOGO

We operate in the pipeline gathering and processing segments of the natural gas midstream industry in
the U.S. and Canada. The operating fundamentals of Canadian natural gas processing operations differ somewhat from those in the U.S. The most significant difference is that, unlike U.S. natural gas processing facilities where the purchaser often
purchases and owns the natural gas that it gathers and processes, in Canadian natural gas processing operations, the processor typically does not take title to the natural gas it gathers and processes. The processor, instead, receives fee income
from transporting and processing natural gas owned by others.

As natural gas is processed to remove unwanted elements that
interfere with pipeline transportation, higher value hydrocarbon liquids such as NGLs and condensate are separated from the raw natural gas stream. NGLs are obtained during the production and processing of natural gas or are a by-product from
the crude oil distillation process within refineries. Supplies of NGLs are determined by the level of natural gas production, the amount of liquids in the gas, refining capacity utilization and by imports of NGLs. Condensate is a mixture
of petroleum products consisting primarily of pentanes and heavier liquids extracted from natural gas. It is used to make gasoline, jet fuel and as a diluent used to dilute crude bitumen so that it can be transported by pipeline. We are engaged in
residential propane supply operations in Page and Payson in Arizona.

##### Table of Contents

Gas Gathering

The natural gas gathering process begins with the drilling of wells into gas bearing rock formations. Once a well has been completed, the well is connected to a gathering system. Gathering systems
typically consist of a network of small diameter pipelines and, if necessary, compression systems that collect natural gas from points near producing wells and transport it to larger pipelines for further transmission.

Gas Dehydration

Wellhead gas is generally fully saturated with water vapor. This water vapor must be removed from the gas stream to prevent formation of
hydrates and condensation of free water in downstream facilities, to prevent corrosion and to meet downstream pipeline quality specifications. Dehydration is generally performed at central points along an upstream gathering system utilizing either a
glycol absorption process or a solid desiccant adsorption process.

Gas Treating

In addition to water vapor, wellhead gas contains impurities such as carbon dioxide, nitrogen, hydrogen sulfide, helium, oxygen and other
inert components. These impurities must be removed from the gas stream to protect downstream equipment, prevent corrosion and meet downstream pipeline quality specifications. They are removed through a variety of processes utilizing chemical
reaction, absorption, adsorption or permeation.

Gas Processing

Natural gas delivered to the burner tip is almost pure methane. However, natural gas is produced from the reservoir containing impurities
and heavier hydrocarbons entrained in the gas stream. The heavier hydrocarbons of NGLs must be removed from the wellhead gas stream before the gas is transported to market. These heavier hydrocarbons are removed by processing the gas at
plants, either through temperature and pressure manipulation or absorption. The extracted heavier hydrocarbons have a high value and are sold separately to petrochemical manufacturers or wholesale marketers.

NGL Terminalling, Storage and Supply

The production of NGLs by gas processing plants and refineries is fairly constant throughout the year, whereas demand is seasonal. NGL terminalling and storage serves to balance this constant production
or supply with the seasonal demand. Supply and marketing agreements are entered into with gas processors and refiners to market production on the supply side. This supply is then marketed to petrochemical plants and retail customers, as well as
other consumers of NGLs.

Overview of North American NGL Hubs

There are four major North American NGL trading centers located at Edmonton, Alberta; Sarnia, Ontario; Conway, Kansas; and Mont Belvieu,
Texas. These locations have substantial underground storage and are connected to NGL supply, transmission and distribution systems. Edmonton and Conway serve the U.S. midwest market while Sarnia and Mont Belvieu serve the U.S. northeast market. Mont
Belvieu is the price reference point for North American NGL markets as it is the largest consuming region. Its strategic location on the Gulf Coast allows access to supplies from Europe, Africa and the Middle East. Mont Belvieu also has significant
storage and pipelines to transport liquids to market and is close to large crude oil refineries. Petrochemical demand is approximately 42% of NGL demand and is the main factor affecting Mont Belvieu NGL prices. The two largest contributors to
overall demand are weather, since propane is used in home heating and crop drying, and the petrochemical industrys requirement for ethane. In general, NGLs are priced higher than natural gas to cover the cost for extraction.

Mexican Asphalt Industry

Mexico is the 14th largest country in the world based on land area and the 11th largest country in terms of population. Although its land area is only one-fifth the size of the U.S., Mexico has a
population of roughly one-third that of the U.S. Mexico has a large and diverse road network in place. Mexicos land transportation network is one of the most extensive in Latin America with over 220,000 miles of paved roads. Roads are a
critically important component of Mexicos transportation infrastructure, with 99% of its passengers and 59% of its cargo being transported over road surfaces. The use of rail and water transportation in Mexico, in most cases, is either not
practical or not available. As a result, roads are a high priority item of the country. The total current demand for road asphalt products in Mexico is roughly 2.1 million metric tons per year, requiring approximately 1.8 million metric
tons of asphalt, either as a raw material or for end-use.

Mexicos national highway infrastructure is comprised of three
main components: the federal network (which includes both toll and toll-free roads) accounting for approximately 13% of all roads, the regional network accounting for approximately 21%, and the rural network consisting of approximately 66%. The
federal road system is the responsibility of the Secretary of Communications and Transportation (SCT), while the regional network of roads is the responsibility of state governments. Rural and state roads and low-volume roads are also improved by
the states. These networks help establish the annual demand for asphalt. Asphalt demand can increase, or decline, at a pace comparable to the level of on-going highway expansion and/or maintenance projects. Such projects rely on the availability of
government concessions, continued public-private partnership undertakings and locally funded ventures.

European Petroleum Products Storage
Industry

Storage for refined products and crude oil is critical to the European economy. Fluctuations in demand for
crude oil and transportation fuels, combined with changing flows of petroleum product production and refining capacity, means storage is necessary to balance demand. Additionally, supply and demand disruptions due to weather, industry upsets,
political tensions and terrorism have forced industry participants to understand the significance that access to storage, and the availability of storage, will have over the future years.

The independent storage industry has experienced fluctuating demand for its services over recent years from major oil companies, oil
traders and strategic storage agencies (government entities that store fuel to protect against significant fluctuations in supply or demand as mandated by the European Union and the International Energy Agency). The construction of new tank storage
facilities has historically been restricted, resulting in a supply shortage. However, high crude oil prices and backwardated market conditions (i.e., prices for future deliveries are lower than current prices) have had a negative effect on storage
economics. As a result, demand for such storage facilities is currently weak.

Our Business

We provide gathering, transportation, storage, distribution, marketing and other midstream services primarily to independent producers,
refiners of petroleum products and other market participants located in the Midwest and Rocky Mountain regions of the U.S., Canada and the West Coast of 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 between 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 terminals throughout
Mexico.

We gather, purchase, transport, store, distribute and market petroleum products to markets primarily in the Midwest,
ensuring that our customers have consistent access to petroleum products supply and markets. Our strategically located pipelines, terminals and storage tanks, with access to North American transportation pipeline interconnects, are well positioned
to benefit from the continuing need to transport and gather petroleum products from areas of supply to areas of demand.

information regarding the principal business and services rendered, assets and operations and markets and competitive strengths. Our results of operations and financial condition are subject to a variety of risks. For information regarding our key
risk factors, see Item 1A. Risk Factors.

Crude

Crudes business operations are conducted through its 51% ownership interest in White Cliffs Pipeline, L.L.C. (which Crude operates)
and a 2% general partner interest and 57.0% limited partner interest in Rose Rock. These operations include crude oil transportation, storage, terminalling, gathering and marketing in Colorado, Kansas, Montana, North Dakota, Oklahoma and Texas for
third party customers as well as for itself. The Crude business unit consists of three primary operations: (i) Kansas and Oklahoma pipeline system (Rose Rock); (ii) Cushing storage (Rose Rock); and (iii) the White Cliffs Pipeline. A
majority of Crudes revenue is generated from fee-based contractual arrangements that, in some instances, are fixed and not dependent on usage. For purposes of this discussion of Crudes operations, all Rose Rock and White Cliffs Pipeline
operations will be referred to as Crude.

Assets and Operations

Cushing Storage. Crude owns and operates over 5.0 million barrels of crude oil storage in Cushing, Oklahoma, with an
additional 1.95 million barrels of crude oil storage under construction. Crude directly utilizes, and provides to customers, fee-based storage and terminal services from owned assets in Cushing. Currently, most of our owned operating storage
capacity at Cushing is leased to third-party customers. Crude also owns and operates a delivery/receipt pipeline to connect its storage operations to Enterprise Products Partners, LPs facility in Cushing, which is the hub where all NYMEX
barrels are delivered. We have additional acreage and infrastructure in place to significantly expand storage capacity at Cushing.

Kansas and Oklahoma Pipeline.Crude owns and operates an approximately 640-mile crude oil gathering and transportation pipeline system and related pipeline storage tanks in Kansas and northern
Oklahoma. The pipeline system connects to several third party trunk pipelines in Kansas, several refineries, and storage terminals located at Cushing, Oklahoma. The Kansas and Oklahoma pipeline system can currently transport approximately
40,000 barrels of crude oil per day.

White Cliffs Pipeline.Crude owns and operates a modern, ten-lane crude oil truck
unloading facility in Platteville, Colorado, which connects to the origination point of the White Cliffs Pipeline, which was first placed into service in 2009. Substantially all of the crude oil production from the DJ Basin and nearby Niobrara Shale
must initially be transported by truck due to a shortage of gathering capacity, and the White Cliffs Pipeline is the only direct pipeline out of the DJ Basin to the Cushing market and to Mid-Continent refineries. Throughput at the facility averaged
32,400 barrels per day and 25,800 barrels per day for the years ended December 31, 2011 and 2010, respectively. The facility includes 220,000 barrels of crude oil storage capacity.

Crude also owns 51% of, and operates, a 527-mile common carrier, crude oil pipeline system that originates in Colorado and terminates in
Cushing, Oklahoma (the White Cliffs Pipeline). The White Cliffs Pipeline provides the Denver-Julesburg Basin (DJ Basin) producers in Colorado direct access to the Cushing market and to refiners in the Midwest area. The White
Cliffs Pipeline also includes a 100,000 barrel crude oil storage tank and a truck unloading facility owned and operated by Crude and located and connected at the White Cliffs Pipelines origination point at Platteville, Colorado. The White
Cliffs Pipelines capacity is 70,000 barrels of

##### Table of Contents

crude oil per day. The White Cliffs Pipeline became fully operational on June 1, 2009. Crude currently owns 51% of the White Cliffs Pipeline. The other 49% is owned as follows: 34% by Plains
Pipeline, L.P. (Plains), 10% by Anadarko Wattenberg Company, LLC (AWC) and 5% by Samedan Pipe Line Corporation (Noble Energy). AWC and Noble Energy have each entered into throughput agreements with us for the
shipment of their product on the White Cliffs Pipeline. (See Note 5 of our consolidated financial statements beginning on page F-1 of this Form 10-K for additional information.)

In addition to these operations, Crude conducts a crude oil aggregation, marketing and blending business in the Bakken shale play area in
North Dakota, utilizing two truck unloading facilities. Crude oil is purchased, transported via owned trucks, shipped on an Enbridge Pipeline (utilizing a historical pipeline allocation) or via rail and marketed. (This part of the Crude business was
previously conducted by SemCanada Crude, but prior to the sale of the SemCanada Crude assets, as previously noted, this activity was transferred to Crude.) There are currently more rigs working in this shale play than any other in the U.S. As more
volume moves southeast from the Bakken to Cushing, our assets are very well positioned to benefit in an upsurge in activity.

Revenue and Marketing

A majority of Crudes revenue is derived from fee-based contractual arrangements with third party customers. The White Cliffs Pipeline has two throughput contracts that require each shipper to pay a
minimum fixed monthly payment for the capacity allocated to it on the pipeline, regardless of the capacity actually utilized. The agreements run through May 2014, although they could end sooner if the contracted volumes are shipped before that
date. In addition, other parties may ship on White Cliffs Pipeline at FERC based rates. The Kansas and Oklahoma pipeline system provides transportation and storage services to customers on fee-based arrangements, typically based on usage with
varying term lengths. Cushing storage capacity is provided to customers under fixed fee contractual arrangements, typically based on the amount of storage capacity reserved for each customer.

In addition to third party customer revenue, Crude generates revenue from limited marketing activities. Crudes U.S. marketing
includes purchasing crude oil for its own account from producers and aggregators and selling crude oil to traders and/or refiners.

We mitigate the commodity price exposure of our crude oil marketing operations by limiting our net open positions through (i) the concurrent purchase and sale of like quantities of crude oil to
create back-to-back transactions intended to lock in positive margins based on the timing, location or quality of the crude oil purchased and delivered, or (ii) derivative contracts. All of our marketing activities are subject to
our comprehensive risk management policy which establishes limits in order to manage risk and mitigate financial exposure. Our marketing activities account for a portion of the revenue we generate on our Kansas and Oklahoma pipeline system and
through our Bakken Shale operations.

Market and Competitive Strengths

Crudes pipelines are located in areas where they have the ability to move crude oil to Cushing. The Cushing Interchange is one of
the largest crude oil marketing hubs in the U.S. and the designated point of delivery specified in all NYMEX crude oil futures contracts. As the NYMEX delivery point and a cash market hub, the Cushing Interchange serves as a significant source of
refinery feedstock for PADD 2 refiners and plays an integral role in establishing and maintaining markets for many varieties of foreign and domestic crude oil. The White Cliffs Pipeline is the only direct route out of the DJ Basin in Colorado to
Cushing. The Kansas/Oklahoma pipeline system allows Kansas producers and purchasers access to local refineries and Cushing.

SemStream

SemStream is engaged in the residential propane supply business through its wholly-owned subsidiary, SemStream Arizona
Propane, L.L.C. (SemStream Arizona), with operations in Page and Payson, Arizona and holds our interests in NGL Energy Partners LP.

SemLogistics

SemLogistics owns the largest independent petroleum
products storage facility in the U.K. The main activities of SemLogistics are the receipt, storage and redelivery of clean petroleum products and crude oil at the Milford Haven site.

Assets and Operations

SemLogistics operates a tank storage business and offers build-bulk (importing small cargos, building volume and exporting larger cargos) and break-bulk (importing larger cargos and exporting smaller
cargos) operations to its customers that transport products from the Middle East to Europe, the east coast of the U.S. and the west coast of Africa. The terminal is strategically located to access the U.K. market and to service numerous global
markets.

SemLogistics storage facility includes approximately 8.7 million barrels of above ground storage tanks
and has received approval from Pembrokeshire County Council to build nine new tanks with a total storage capacity of 1.5 million barrels. The construction of new tankage is dependent on, and will commence when, the supply and demand for
additional product storage is prudent. The terminal has two deep water jetties, one of which can accommodate vessels of up to 165,000 dead weight tons. It also has access to Mainline Pipeline Limited (pipeline from Milford Haven to Manchester and
Nottingham), which is owned by four major oil companies.

Over 40% of SemLogistics storage capacity is multi-product,
providing customers with tank storage for clean petroleum products, including gasoline, gasoline blendstocks, jet fuel, gas oil and diesel. The remaining tankage is either dedicated to crude oil or dual-purpose tankage for at least two clean
petroleum products (gasoline/jet fuel or gasoline/gas oil or jet fuel/gas oil). SemLogistics also provides related services, e.g., tank-to-tank transfers, mixing of gasoline blendstocks, and kerosene marking.

Revenue and Marketing

SemLogistics generates revenue from fixed-fee storage tank leasing and related services by making available to third parties all of the
terminals available tank capacity for the storage of crude oil and refined products. Customers fall into three broad categories: trading, structural marketing storage and compulsory strategic storage.

Markets and Competitive Strength

SemLogistics ability to handle multiple products provides flexibility to change its operations in response to market conditions. Demand for independent storage terminals can be impacted by a wide
range of influences such as the forward price curve, expanding oil production, security of supply concerns, European compulsory stock holding requirements, and mismatches in regional production and consumption of oil and refined petroleum products.

SemLogistics terminal size (approximately 23% of the total independent storage in the U.K.) and its vessel handling
capabilities make it unique compared with other terminals. In addition to being the only independent U.K. facility that serves the bulk trans-shipment sector, it is also the only facility capable of handling crude oil, with the only other comparable
facility in the British Isles being a terminal in Ireland. However, the owner of this other facility, a major oil company, uses its terminal exclusively for proprietary storage and storage of Irish strategic stocks.

SemCAMS

We own
and operate four natural gas processing and gathering facilities in Alberta, Canada. The principal process performed at the processing plants is to sweeten sour natural gas by removing sulfur. Approximately two-thirds of the total
natural gas throughput at our processing plants is sour gas. All of SemCAMS assets are located in West-Central Alberta, in the heart of the Western Canadian Sedimentary Basin, which accounts for approximately 80% of Canadas sour natural
gas production.

Assets and Operations

SemCAMS owns and operates varying working interests in (i) two sour natural gas processing plants known as the Kaybob South No. 3 plant (the K3 Plant), and the Kaybob Amalgamated
plant (the KA Plant); (ii) two sweet gas plants known as the West Fox Creek plant and the West Whitecourt plant (the WW Plant), and (iii) a network of more than 600 miles of natural gas gathering and transportation
pipelines. The sour gas plants are dually connected to two major long-haul natural gas pipelines that serve Canada and the U.S. The plants also have the ability to load product for transportation by truck and railcar.

Revenue and Marketing

SemCAMS generates revenue from the processing plants through volumetric fees for services under contractual arrangements with working interest owners and third party customers. SemCAMS does not have
direct exposure to commodity prices. In addition, SemCAMS generates fee-based revenue from volume throughput on its pipelines. SemCAMS customers include producers of varying sizes.

SemCAMS also derives revenue as the operator of pipeline gathering systems that gather gas from multiple wells located in the same
production unit and as the operator of pipeline transportation systems that deliver the gathered gas to each plant.

To
support operations at our plants, several producers have committed to process all of their current and future natural gas production from lands owned by them, or their subsequent assignees, within a dedicated area comprised of
approximately 180 townships located in and around our plants. The dedicated area covers approximately 27% of the volumes in the area surrounding our plants. This dedication continues until field depletion.

##### Table of Contents

Market and Competitive Strengths

SemCAMS natural gas gathering and processing operations are located in an area that generates more than 95% of Canadas total
natural gas production and approximately 80% of Canadas total sour gas production. Natural gas is used for a variety of purposes in Canada including heating, electricity production and other industrial processes.

SemMexico

SemMexico provides a variety of liquid asphalt cement products and product application services to the Mexican market. SemMexico
purchases, produces, stores and distributes asphalt products throughout Mexico. SemMexicos primary supplier of asphalt is Pemex, Mexicos state-owned petroleum company. SemMexico is the largest asphalt distributer in Mexico and, in
addition to direct asphalt cement sales, further processes asphalt materials in combination with other raw materials to produce value-added products. These products, such as polymer modified asphalts and asphalt emulsions, are then sold to road
contractors and government agencies.

Assets and Operations

SemMexico currently operates an in-country network of 12 asphalt cement terminals and modification facilities, two emulsion distribution
terminals and one portable rail unloading facility to import asphalt from the U.S. SemMexicos national technical center and headquarters are located in the city of Puebla, Mexico.

Revenue and Marketing

SemMexico generates revenues through the sale of asphalt product to customers. In general, SemMexicos sales and purchases of asphalt cement are matched; SemMexico procures product on an as-needed
basis, thereby limiting exposure to price movements of inventory. SemMexicos focus is to maintain its reputation as a quality supplier of asphalt products by consistently producing high quality products and introducing technologically advanced
products and solutions to Mexicos asphalt market, while simultaneously increasing production capacity and product distribution availability.

Market and Competitive Strengths

SemMexico is a leader in asphalt pavement
technologies and capabilities. It is the only liquid asphalt cement company with a national footprint in Mexico. These factors have resulted in a long-term supply relationship with Pemex and continuous business transactions with its customers.
SemMexico is exposed to market risk, such as the sustainability of road construction and maintenance funds from the Mexican government. However, we believe that SemMexicos significant market position, reputation, technology and long-term
relationships with suppliers and customers are strategic strengths that will benefit SemMexico if funding or demand should increase.

SemGas

SemGas
provides natural gas gathering and processing services. It has gathering and processing plants and assets in Kansas, Oklahoma and Texas. SemGas aggregates gas supplies from the wellhead and provides various services to producers that condition the
wellhead gas production for downstream markets.

Assets and Operations

SemGas currently owns and operates over 800 miles of gathering pipelines in Kansas, Oklahoma and Texas. SemGas has one processing plant
located in Sherman, Texas, with a processing capacity of 23 million cubic feet per day and over 400 miles of low pressure gathering lines. SemGas also has two plants in Northern Oklahoma (Nash and Hopeton) located roughly 20 miles apart, with a
combined processing capacity of approximately 55 million cubic feet per day. This area, also called the Mississippi Zone, has emerged into a key oil resource

##### Table of Contents

play with associated gas. There are approximately 690,000 acres dedicated to SemGas, from several area producers, with about 60,000 acres in the core of the emerging Mississippian play.

Additionally, SemGas owns a Eufaula gathering system which gathers, dehydrates and compresses gas in eastern Oklahoma, and a
gathering system in Kansas.

Revenue and Marketing

SemGas generates revenue from a portfolio of contracts. Initial contract terms can range from two years to the life of the reserves
and, upon expiration, continue to renew on a month-to-month or year-to-year evergreen basis. The majority of the contracts provide upside potential by providing SemGas participation in commodity price and processing margin upswings through
percent-of-proceeds and percent-of-index contracts. On these contracts, SemGas is generally responsible for marketing the gas and NGLs for both its and the producers share of the products. Percent-of-proceeds contracts are based on SemGas
paying the producers a percentage of the sale proceeds from the products and percent-of-index contracts are based on SemGas paying the producers a percentage of the sale proceeds based on an index price. SemGas also has fee-based contracts for
processing and gathering services. SemGas customers include producers, operators, marketers and traders.

Market and
Competitive Strengths

SemGas gathering and processing volumes can be impacted by market demand for the products it
handles, as well as the price for crude oil because the Mississippi Zone is primarily a crude oil play with associated natural gas and natural gas liquids. Gathering and processing activities are also reliant on continued drilling and production
activity by producers in our areas of operation. While price increases in natural gas might lead to increased drilling and supply, price increases can also adversely affect demand.

We face competition in acquiring new natural gas supplies. The natural gas gathering and processing industry is generally characterized
by regional competition, based on the proximity of gathering systems and processing plants to natural gas producing wells. SemGas gathering and processing assets tend to have relatively long-term contracts and, in some instances, are the only
assets that can provide the offered services to the customers.

SemGas generally sells all natural gas and NGLs it obtains
under its percentage-of-proceeds and percentage-of-index contracts immediately in the spot market and, therefore, has little commodity price risk with respect to inventory or other physical commodity positions. SemGas percentage-of-proceeds
and percentage-of-index processing contracts intrinsically have commodity price risk since SemGas fees, with respect to these contracts, vary with the level of natural gas and commodity prices. SemGas may elect to use financial derivatives to
hedge this risk. SemGas is limited in the amount, and in the time period, for which it may hedge its commodity price risk associated with its contracts pursuant to our Comprehensive Risk Management Policy. More generally, all of our marketing and
hedging activities are subject to our Comprehensive Risk Management Policy which establishes a set of limits, both at the SemGas and the SemGroup Corporation levels, to manage risk and mitigate financial exposure.

Risk Governance and Comprehensive Risk Management Policy

We expect to generate the majority of our earnings from owning and operating strategic assets while endeavoring to prudently manage all risks, including commodity price risk, associated with the ownership
and operations of our assets. We have a Comprehensive Risk Management Policy that reflects an enterprise-wide approach to risk management and considers both financial and non-financial risks.

Our Board of Directors is responsible for the oversight of our enterprise-wide risk and has approved our Comprehensive Risk Management
Policy. The Comprehensive Risk Management Policy is designed to ensure we:



| |  |  | identify and communicate our risk appetite and risk tolerances;
| | - |  | ---------------------------------------------------------------

The Audit Committee of our Board of Directors has oversight responsibilities for the implementation of, and compliance with, our Comprehensive Risk Management Policy.

Our Executive Management Committee, comprised of corporate officers, oversees the financial and non-financial risks associated with all
activities governed by our Comprehensive Risk Management Policy including:

| |  |  | other strategic activities.
| | - |  | ---------------------------

We also have a Risk Management Group that is assigned responsibility for independently monitoring compliance with, reporting on, and enforcing the provisions of our Comprehensive Risk Management Policy.

Our Comprehensive Risk Management Policy provides a set of limits or thresholds for activities related to owned assets,
physical commodities, and derivatives and capital transactions involving market and credit risk. Our limits monitor these risks for each individual segment and on a consolidated basis. Our Comprehensive Risk Management Policy also specifies the
types of transactions that may be executed by incumbents of named positions without specific approval of our Board of Directors or our Executive Management Committee. It also restricts proprietary trading activities within limits significantly more
restrictive than the corporate market risk management limits.

Competition

We face intense competition in the operations of each of our segments. Our competitors include other midstream companies, major integrated
oil companies and their marketing affiliates, crude oil pipeline companies and independent gatherers, brokers and marketers of petroleum products of widely varying sizes, financial resources and experience. Some of these competitors have capital
resources many times greater than ours and control greater supplies of crude oil and petroleum products. Competition for customers of petroleum products is based primarily on price, access to supply, access to logistics assets, distribution
capabilities, the ability to meet regulatory requirements, and maintenance of quality of service and customer relationships.

Operational
Hazards and Insurance

Pipelines, terminals, storage tanks, processing plants or other facilities may experience damage as
a result of an accident, natural disaster or deliberate act. These hazards can also cause personal injury and loss of life, severe damage to, and destruction of, property and equipment, pollution or environmental damage and suspension of operations.
Through the services of a major national insurance broker, we have maintained insurance of various



16



---

##### Table of Contents

types and varying levels of coverage similar to that maintained by other companies in the industry and which we consider adequate, under the circumstances, to cover our operations and properties,
including coverage for natural catastrophes, pollution related events and acts of terrorism and sabotage. The limit of operational insurance maintained covering loss of, or damage to, property and products is $300 million per loss and includes
business interruption loss. For claims arising under general liability, automobile liability and excess liability, the limits maintained total $250 million per occurrence/claim. Primary and excess liability insurance limits maintained for pollution
liability claims vary by location for claims arising from gradual pollution with limits ranging from $20 million to $40 million in the aggregate. The combined primary and excess liability insurance limits for claims arising from sudden and
accidental pollution total $270 million per claim and $290 million in the aggregate. This insurance does not cover every potential risk associated with the operating pipelines, terminals and other facilities. We have a favorable claims history
enabling us to self-insure the working layer of loss activity utilizing deductibles and self-insured retentions commensurate with our financial abilities and in line with industry standards, in order to create a more efficient and cost
effective program and a consistent risk profile. The working layer consists of high frequency/low severity losses that are best retained and managed in-house. Sizeable or difficult self-insured claims or losses may be handled by professional
adjusting firms hired by us. We will continue to monitor the appropriateness of our deductibles and retentions as they relate to the overall cost and scope of our risk and insurance program.

With a few limited exceptions, our customers have not agreed to indemnify us for losses arising from a release of crude oil, and we may
instead be required to indemnify our customers in the event of a release or other incident.

Regulation

General

Our
operations are subject to extensive regulation. The following discussion of certain laws and regulations affecting our operations should not be relied on as an exhaustive review of all regulatory considerations affecting us, due to the myriad of
complex federal, state, provincial, foreign and local regulations that may affect our business.

Regulation of U.S. Pipeline and Storage
Operations

Interstate Storage and Transportation

White Cliffs Pipeline is subject to regulation by the Federal Energy Regulatory Commission (FERC) because the rates charged to
shippers on the pipeline system are required to be filed with, and accepted by, FERC. Under the Interstate Commerce Act (the ICA), FERC has authority to regulate companies that provide interstate petroleum based products pipeline
transportation services, including pipeline operational transportation related storage services. FERCs authority to regulate those interstate services includes the rates charged for services, terms and conditions of service, maintenance of
accounts and records and various related ancillary matters. Regulated companies may not charge rates that have been determined not to be just and reasonable by FERC. The rates, terms and conditions for our service are found in
FERC-approved tariffs. Pursuant to FERCs jurisdiction over rates, existing rates may be challenged by complaint and proposed rate increases and proposed changes in terms and conditions of service may be challenged by protest. In addition, FERC
prohibits petroleum and NGL based products transportation from unduly preferring, or unreasonably discriminating against, any person with respect to pipeline rates or terms and conditions of service.

Gathering and Intrastate Pipeline Regulation

The ICA, the Natural Gas Act (the NGA) and the Natural Gas Policy Act of 1978 do not apply to intrastate petroleum and natural gas based products facilities and activities, i.e., those that
are not used or usable in the conduct of interstate commerce. FERC has ruled that intrastate petroleum and natural gas gathering



17



---

##### Table of Contents

systems are exempt from regulation by the Commission. We own a number of natural gas pipelines that we believe operate wholly intrastate and are, therefore, exempt from FERC regulation. We also
own a number of intrastate crude oil gathering systems that are subject to state and local, but not federal regulation. These gathering systems are currently operated as proprietary systems and may be subject to regulation by FERC in the future.

In the states in which we operate, regulation of intrastate natural gas and crude oil gathering facilities and intrastate
crude oil pipeline service generally includes various safety, environmental and, in some circumstances, nondiscriminatory take requirements and complaint-based rate regulation. For example, our natural gas gathering facilities are, in some cases,
subject to state ratable take and common purchaser statutes. Ratable take statutes generally require gatherers to take, without undue discrimination, natural gas production that may be tendered to the gatherer for handling. Common purchaser statutes
generally require gatherers to purchase without undue discrimination as to source of supply or producer. These statutes are designed to prohibit discrimination in favor of one producer over another producer or one source of supply over another
source of supply. These statutes have the effect of restricting our right, as an owner of gathering facilities, to decide with whom we contract to purchase or transport natural gas.

Department of Transportation

All crude oil and liquefied petroleum gases interstate pipelines, and certain intrastate crude oil and liquefied petroleum gases pipelines and storage facilities, are subject to regulation by the
Department of Transportation (the DOT) with respect to the design, construction, operation and maintenance of the pipeline systems and storage facilities. The DOT routinely conducts audits of the regulated assets and we must make certain
records and reports available to the DOT for review as required by the Secretary of Transportation. In some states, the DOT has given a state agency authority to assume all or part of the regulatory and enforcement responsibility over the intrastate
assets.

Regulation of NGL Terminals, Distribution and Utility Operations

SemStreams Arizona non-regulated and regulated propane distribution operations are subject to the code set forth in the National
Fire Protection Association Standard #58 (NFPA 58), Standard for the Storage and Handling of Liquefied Petroleum Gases. Arizona state agencies routinely conduct physical audits to ensure compliance with such regulations.

SemStream Arizonas utility operations are subject to regulation by the Arizona Corporation Commission (ACC). The ACC
regulates the sale price of propane gas to customers connected to our underground propane gas systems in Payson and Page, Arizona. The ACC also conducts annual inspections of the Payson and Page utility underground pipeline systems under authority
delegated to it from the DOT.

Trucking Regulation

Through our interest ownership in Rose Rock, we operate a fleet of trucks to transport crude oil. We are licensed to perform both
intrastate and interstate motor carrier services and are subject to certain safety regulations issued by the DOT. DOT regulations cover, among other things, driver operations, maintaining log books, truck manifest preparations, the placement of
safety placards on the trucks and trailer vehicles, drug and alcohol testing, safety of operation and equipment and many other aspects of truck operations. We are also subject to Occupational Safety and Health Administration (OSHA)
regulations with respect to our trucking operations.

Cross-Border Regulation

We are subject to regulatory matters specific to border crossing, which include export licenses, tariffs, customs and tax issues and toxic
substance certifications. Regulations include the Short Supply Controls of the



18



---

##### Table of Contents

Export Administration Act, the North American Free Trade Agreement, National Energy Board Reporting and Certification and the Toxic Substances Control Act. Violations of license, tariff and tax
reporting requirements under these regulations could result in the imposition of significant administrative, civil and criminal penalties. Furthermore, the failure to materially comply with applicable tax requirements could lead to the imposition of
additional taxes, interest and penalties.

Regulation of Canadian Gathering, Processing, Transportation and Marketing Businesses

National Energy Board (NEB)

Our Canadian assets are not currently regulated by the NEB. The importation and exportation of natural gas and crude oil to and from
Canada, however, are regulated by the NEB. The Government of Alberta tracks volumes exported from Alberta and, although it has not previously done so, reserves the right to limit the volume of natural gas that may be removed from Alberta in the
event of domestic supply constraint.

Energy Resources Conservation Board (ERCB)

The ERCBs purpose is to ensure that the discovery, development and delivery of Albertas resources take place in an orderly and
efficient manner and in the public interest.

Among other matters, the ERCB has the authority to regulate the exploration,
production, gathering, processing, transmission and distribution of natural gas within the province. With respect to natural gas gathering and processing activities, the ERCBs primary role is to serve as a licensing authority for the
construction and operation of the facilities used in those activities.

While the ERCB has jurisdiction to regulate the rates
and fees charged for services provided by these types of facilities using a public complaint process, this authority is discretionary and historically has not commonly been exercised. Generally, the complaint-based method of regulation has
meant that parties have had the opportunity to use alternative means to resolve disputes without resorting to the ERCB.

Sulphur Recovery Standards

In 2001, the ERCB set more stringent sulphur recovery standards for older sour gas processing plants, as set out in ID 2001-3. This interim directive directed older, grandfathered plants to
either gradually increase their sulphur recovery to current standards or accept a reduction in their licensed capacity.

The
K3 Plant and the KA Plant are capable of meeting de-grandfathered recovery requirements. The K3 Plant was de-grandfathered in 2006 after installation of a new Super Claus Sulphur recovery process. The KA Plant can
be de-grandfathered via simple administrative application.

Other Provincial Regulatory Agencies

The Alberta Boilers Safety Association (ABSA) is the regulatory agency in Alberta of pressure systems with a
mandate to ensure that pressure equipment is constructed and operated in a manner that protects public safety. SemCAMS maintains an approved program to meet all requirements.

Regulation of U.K. Operations

In the U.K., the Department of Energy
and Climate Changes Energy Resources Development Unit is responsible for the regulation of a number of relevant areas, including licensing, fiscal policy, national oil stocks policy (including their compulsory oil stocking obligations as a
member of the European Union and International Energy Agency), policy on oil disposal, offshore environmental policy, oil sharing arrangements and



19

##### Table of Contents

decommissioning. Other regulatory bodies include the Health and Safety Executive, which regulates health and safety in the upstream and downstream oil industry (among others) and the Hazardous
Installations Directorate, which is responsible for inspection and enforcement of health and safety regulation with respect to the downstream oil industry (among others). There is no regulator dedicated specifically to the oil industry. The
activities of SemLogistics may also be regulated as a result of the European Unions participation in the International Carriage of Dangerous Goods by Road and Rail agreements, as well as the International Maritime Dangerous Goods Code, which
governs the safe transport of dangerous goods (including oil) by sea and, in due course, by the Marine Management Organization when it comes into being pursuant to the Marine and Coastal Access Bill.

The Department for Environment Food and Rural Affairs is responsible for setting legislation, policy, regulations and guidance for a
number of environmental issues. There are also several European and international laws and policies that apply. SemLogistics activities are regulated by the Environment Agency Wales (EAW). EAW also oversees spills and their
cleanup, as well as new construction of tanks, bunds (spill prevention berms in the U.S.) and other improvements, and whose regulations require us to maintain a Pollution Prevention and Control permit.

At a local level, SemLogistics storage facility falls within the jurisdiction of the Milford Haven Port Authority (the
MHPA). Under the Milford Haven Port Authority Act 2002, the MHPA has the power to publish directions for the purpose of promoting or securing conditions conducive to the ease, convenience or safety of navigation in Milford Haven and the
approaches to it. MHPA is currently consulting on the Milford Haven Port Authority General Directions (2006). MHPA also has powers and obligations under various regulations, including, among others, the Dangerous Substances in Harbour Areas
Regulations 1987 and the Harbour Docks and Piers Clauses Act 1847, as well as responsibility for the enforcement of the Port Marine Safety Code.

Regulation of Mexican Operations

SemMexico is primarily engaged in
the purchasing, production, modification, storage and distribution of liquid asphalt cement products throughout Mexico. These activities are subject to compliance with environmental laws and regulations under Mexican technical Official
Standards and other provisions that establish minimum technical requirements. Companies are required to obtain, from the corresponding federal, local and/or municipal authorities, the relevant permits and authorizations to construct and
operate asphalt modification plants and carry out the activities described above.

Mexicos Ministry of Communications
and Transportation has published several construction standards establishing the specifications required for asphalt surfaces in connection with infrastructure projects, as well as certain manuals identifying the procedures for verifying compliance
therewith.

Asphalt treatment, storage and distribution activities are considered hazardous under applicable environmental
laws and regulations and are subject to the scrutiny of the Ministry of the Environment and Natural Resources, which is the governmental agency in charge of granting the authorization for the handling, transportation, treatment, storage,
importation, exportation and final disposal of asphalt, among others. These authorizations are essential for SemMexico to be able to perform its activities in Mexico.

Coupled with the authorizations and permits that may be granted by the Ministry of the Environment and Natural Resources, asphalt transportation activities within Mexico are subject to having obtained a
number of other federal and local permits, including federal licenses for the operators of transportation units mobilizing SemMexicos liquid asphalt cement products.

Environmental, Health and Safety Regulation

General

Our operations, including Canadian, U.K. and Mexican operations, are subject to varying degrees of stringent and complex laws and
regulations by multiple levels of government relating to the production, transportation, storage, processing, release and disposal of petroleum and natural gas based products and other materials or otherwise relating to protection of the
environment. As with the industry generally, compliance with current and anticipated environmental laws and regulations increases our overall costs of business, including our capital costs to construct, maintain and upgrade pipelines, equipment and
facilities. The failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, the imposition of removal or remedial obligations and the issuance of injunctions limiting or prohibiting
our activities.

The clear trend in environmental regulation, particularly with respect to petroleum product facilities, is
the placement of more restrictions and limitations on activities that may affect the environment and, thus, any changes in environmental laws and regulations or re-interpretations of enforcement policies that result in costly waste handling,
storage, transport, disposal or remediation requirements could have a material adverse effect on our operations and financial condition. We may be unable to pass on such increased costs to our customers. Moreover, accidental releases, leaks or
spills may occur in the course of our operations and we may incur significant costs and liabilities as a result, including those related to claims for damage to property, natural resources or persons. While we believe that we are in substantial
compliance with existing applicable environmental laws and regulations and that continued compliance with existing requirements would not have a material adverse effect on us, there is no assurance that the current conditions will continue in the
future.

The following is a summary of the more significant current environmental, health and safety laws and regulations to
which our operations are subject.

Water Discharges

Our operations can result in the discharge of pollutants, including oil. The Oil Pollution Act (OPA) was enacted in 1990 and
amends provisions of the Federal Water Pollution Control Act of 1972, as amended, the Clean Water Act, as amended, and other statutes as they pertain to prevention of, and response to, oil spills. The OPA, the Clean Water Act and analogous state,
provincial and local laws, subject owners of facilities to strict, joint and potentially unlimited liability for containment and removal costs, natural resource damages and certain other consequences of an oil spill, where such spill is into
navigable waters, along shorelines or in the exclusive economic zone of the U.S. In the event of an oil spill from one of our facilities into navigable waters, substantial liabilities could be imposed. Spill prevention, control and countermeasure
requirements of these laws require appropriate containment berms or dikes and other containment structures at storage facilities to prevent contamination of soils, surface waters and groundwater in the event of an oil overflow, rupture or leak.

The federal Clean Water Act and analogous state and local laws impose restrictions and strict controls regarding the
discharge of pollutants into waters of the U.S. and state waters, including groundwater in many jurisdictions. Permits must be obtained to discharge pollutants into these waters. The Clean Water Act and analogous state and local laws provide
significant penalties for unauthorized discharges and can impose liability for responding to and cleaning up spills. In addition, the Clean Water Act and analogous state and local laws require individual permits or coverage under general permits for
discharges of storm water runoff from certain types of facilities. These permits may require us to monitor and sample the storm water runoff from certain of our facilities.

Similar measures are in place in Canada at both a federal and provincial level.



21



---

##### Table of Contents

In addition, national, local and European Union regulations and directives in the U.K., and
federal, state and local laws in Mexico, impose similar, but not necessarily always as stringent and detailed, requirements as in the U.S. concerning water resources and the protection of water quality, including those that regulate the discharge of
pollutants and other harmful substances into water, require permits, impose clean-up obligations for spills and releases and impose fines and penalties for non-compliance. However, these countries continue to implement stricter requirements that
approach the requirements in the U.S.

Air Emissions

Our operations are subject to the federal Clean Air Act, as amended, and comparable state and local laws, as well as the federal,
provincial and local Canadian, U.K., European Union and Mexican laws applicable to our Canadian, U.K. and Mexican operations, although not necessarily always as stringent as found in the U.S., at least not presently. These laws and regulations
regulate emissions of air pollutants from various sources, including certain of our plants, compression stations and other facilities, and impose various monitoring and reporting requirements. Pursuant to these laws and regulations, we may be
required to obtain environmental agency pre-approval for the construction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain and comply with the terms of air permits containing
various emissions and operational limitations and utilize specific emission control technologies to limit emissions. We may be required to incur certain capital expenditures in the future for air pollution control equipment and leak detection and
monitoring systems in connection with obtaining or maintaining operating permits and approvals for air emissions. There are significant potential monetary fines for violating air emission standards and permit provisions.

SemCAMS conducts on-going air, soil and ground water monitoring in accordance with license requirements. SemCAMS is required to annually
report all specified emissions from its major facilities to a publically accessible National Pollutant Release Inventory database.

Sour Gas

SemCAMS operates facilities which process and transport sour gas
(gas containing hydrogen sulfide, generally at concentrations of 10 parts per million or more). Due to the highly toxic and corrosive nature of sour gas, sour gas handling is regulated in Canada, at both the provincial and federal level, from the
wellhead to the point of disposal of the sulfur content removed from processing the sour gas. Environmental legislation can also affect the operations of facilities and limit the extent to which facility expansion is permitted. Proposed
facilities are facing increased resistance from community groups which are, in turn, increasing demand for alternate sources of sweetening. In addition, legislation requires that facility sites be abandoned and reclaimed to the satisfaction of
provincial authorities and local landowners. A breach of such legislation may result in the imposition of fines and the issuance of clean-up orders.

To protect the public, pipelines transporting sour gas are required to be equipped with monitoring stations and valves that automatically shut down the flow of the pipeline in response to sudden changes
in pressure or detection of sour gas in the atmosphere. SemCAMS sour gas pipelines are monitored 24 hours per day from a centralized pipeline control center and can be shut down by the attending operators. The distance between automatic
pipeline valves is determined, based on regulated sour gas dispersion modeling, to meet approved emergency protection zone size and public exposure requirements. The integrity of the sour gas pipelines is maintained through the injection of
corrosion inhibition chemicals on an on-going basis. SemCAMS sour gas pipelines are inspected on a regular basis to ensure the integrity of the pipelines and associated facilities.

SemCAMS sour gas plants have continuous sour gas detection equipment, as well as other safety systems which can automatically shut
down and depressure the full plant to a controlled flare system. The plants are attended 24 hours per day and can also be shut down by attending operators.



22

##### Table of Contents

At SemCAMS sour gas processing plants, sulfur recovery and air quality are constantly
monitored to ensure required sulfur recovery and emission standards are met. Existing regulations require a sliding range of recovery depending on throughput. SemCAMS required sulfur recovery ranges vary from 98.3% to 98.8%; operational
history has shown actual recovery above license requirements at 98.7% to 99.2%. Residual sulfur that cannot be removed by processing is incinerated to meet a minimum stack top temperature based on a regulator approved dispersion model.

Climate Change

In response to concerns suggesting that emissions of certain gases, commonly referred to as greenhouse gases (GHGs) (including carbon dioxide (CO2) and methane), are contributing to the warming of the Earths
atmosphere and other climatic changes, the United States Congress has been considering legislation to reduce such emissions. In addition, more than one-third of the states, either individually or through multi-state regional initiatives, have
already begun implementing legal measures to reduce emissions of GHGs, primarily through the planned development of GHG emission inventories and/or GHG cap and trade programs. As an alternative to cap and trade programs, Congress may consider the
implementation of a carbon tax program. The cap and trade programs could require major sources of emissions, such as electric power plants, or major producers of fuels, such as refineries or NGL fractionation plants, to acquire and surrender
emission allowances. Depending on the particular program and scope thereof, we could be required to purchase and surrender allowances for GHG emissions resulting from our operations. Depending on the design and implementation of carbon tax programs,
our operations could face additional taxes and higher cost of doing business. Although we would not be impacted to a greater degree than other similarly situated midstream energy service providers, a stringent GHG control program could have an
adverse effect on our cost of doing business and could reduce demand for the natural gas and NGLs we gather and process.

On December 15, 2009, the U.S. Environmental Protection Agency (the EPA), issued a notice of its final finding and determination that emissions of CO2, methane, and other GHGs present an endangerment to public health and
the environment because emissions of such gases contribute to warming of the earths atmosphere and other climatic changes. This final finding and determination allows the EPA to begin regulating GHG emissions under existing provisions of the
Clean Air Act. Accordingly, the EPA has adopted regulations that require a reduction in emissions of GHGs from motor vehicles and also trigger permit review for GHG emissions from certain stationary sources. In addition, the EPA issued a final rule,
effective in December 2009, requiring the reporting of GHG emissions from specified large GHG emission sources in the U.S., beginning in 2011 for emissions occurring in 2010 (EPAs Greenhouse Gas Reporting Program (GHGRP)). Further,
on November 8, 2010, EPA finalized new GHG reporting requirements for upstream petroleum and natural gas systems, which will be added to EPAs GHG Reporting Rule. Facilities containing petroleum and natural gas systems that emit 25,000
metric tons or more of CO2 equivalent per year will be required to report annual GHG emissions to EPA, with the first report due on March 31, 2012. In December 2010, the EPA issued three concurrent actions related to its GHGRP which require the
collection of certain additional business related data, and therefore, it is deferring the reporting of certain information.

In March 2011, the U.S. House of Representatives Energy and Power Subcommittee passed the Energy Tax Prevention Act of 2011 (H.R. 910),
which would prevent the EPA from regulating greenhouse gases for the purpose of addressing climate change. Although it is not possible at this time to predict how legislation or new regulations that may be adopted to address GHG emissions would
impact our business, any such new federal, state or regional restrictions on emissions of CO2 that may be imposed in areas in which we conduct business could also have an adverse effect on our cost of doing business and demand for the petroleum
products we gather, process, transport, store, distribute and market.

SemCAMS has been required to file provincial GHG
emissions reports annually since 2003 for its three large gas plants. GHG baselines were set based on 2003 through 2005 data. Alberta facilities that emit more than 100,000 tonnes of GHG per year have to reduce emissions intensity by 12
percent. Companies can meet this

obligation through improvements to their operations, by purchasing Alberta-based credits, by contributing to the Climate Change and Emissions Management Fund or any combination
thereof. Beginning with the last half of the 2007 reporting year, penalties (CDN $15 per tonne) are paid to the provincial government when the GHG intensity (GHG emissions per unit of production) are greater than 88% of the intensity
established in the baseline data. All GHG costs paid by SemCAMS are recovered by allocation to the producers based on fuel gas use and CO2 composition in the inlet gas. Failure to comply with the regulation will result in a fine of $200 for
every tonne of CO2 by which the total release of specified gases exceeds the net emissions intensity limit for the facility. Legislation to further lower the current reporting limit is pending which, if enacted, would require additional SemCAMS
facilities to file provincial GHG emissions reports annually.

Hazardous Substances and Wastes

The environmental laws and regulations affecting our operations relate to the release of hazardous substances or solid wastes into soils,
groundwater and surface water, and include measures to prevent and control pollution. These laws and regulations generally regulate the generation, storage, treatment, transportation and disposal of solid and hazardous wastes, and may require
investigatory and corrective actions at facilities where such waste may have been released or disposed. For instance, the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), also known as the
Superfund law, and comparable state laws, impose liability, without regard to fault or the legality of the original conduct, on certain classes of persons that contributed to a release of hazardous substance into the
environment. Potentially responsible persons can include the current owner or operator of the site where a release previously occurred and companies that disposed, or arranged for the disposal, of the hazardous substances found at the site. Under
CERCLA, these persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies.
CERCLA also authorizes the EPA and, in some cases, third parties to take actions in response to threats to the public health or the environment and to seek to recover from the potentially responsible classes of persons the costs they incur. It is
not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by hazardous substances or other wastes released into the environment. Although petroleum, as well as
natural gas and NGLs, have been for the most part excluded from CERCLAs definition of a hazardous substance, in the course of ordinary operations, we may generate wastes that may fall within the definition of a hazardous
substance. In addition, there are other laws and regulations that can create liability for releases of petroleum, natural gas or NGLs. Moreover, we may be responsible under CERCLA or other laws for all or part of the costs required to clean up
sites at which such wastes have been disposed. We have received notification that we are one of four companies that may be potentially responsible for any cleanup costs required under the State of Washingtons CERCLA equivalent statute with
respect to a site in Spokane, Washington as result of the our having leased the site after the contamination occurred. No clean-up has yet been ordered. Our position is that, as a result of our emergence from the Bankruptcy, any potential claims
against us for regulatory agency oversight costs were converted to administrative priority claims and any potential claims against us for investigation and clean-up costs were converted to unsecured claims (as they relate to other potentially
responsible persons) and to administrative priority claims (as they relate to any regulatory agency).

We also generate, and
may in the future generate, both hazardous and nonhazardous solid wastes that are subject to requirements of the federal Resource Conservation and Recovery Act (RCRA) and/or comparable state laws. We are not currently required to comply
with a substantial portion of the RCRA requirements because our operations generate minimal quantities of hazardous wastes as currently defined under RCRA. From time to time, the EPA and state regulatory agencies have considered the adoption of
stricter disposal standards for nonhazardous wastes, including crude oil and natural gas wastes. Moreover, it is possible that some wastes generated by us that are currently classified as nonhazardous may in the future be designated as
hazardous wastes, resulting in the wastes being subject to more rigorous and costly management and disposal requirements. Changes in applicable laws or regulations may result in an increase in our capital expenditures, facility operating
expenses or otherwise impose limits or restrictions on our operations.

##### Table of Contents

National, provincial and local laws of Canada, Mexico, the U.K. and the European Union that
are applicable to our operations also regulate the release of hazardous substances or solid wastes into soils, groundwater and surface water, and include measures to prevent and control pollution as well as the handling of hazardous waste. Some of
the requirements are similar to those found under CERCLA and RCRA and some are not yet as stringent, but are becoming more so as the focus on these issues increases.

We currently own or lease, and have in the past owned or leased, and in the future we may own or lease, properties that have been used over the years for petroleum product operations. Solid waste disposal
practices within the oil and natural gas and related industries have improved over the years with the passage and implementation of various environmental laws and regulations. Nevertheless, some petroleum products and other solid wastes have been
disposed of on, or under, various properties owned or leased by us during the operating history of those facilities. In addition, a number of these properties may have been operated by third parties over whom we had no control as to such
entities handling of petroleum products or other wastes and the manner in which such substances may have been disposed of or released. These properties and wastes disposed thereon may be subject to CERCLA, RCRA and analogous state laws. Under
these laws, we could be required to remove or remediate previously disposed wastes or property contamination, including groundwater contamination, or to take action to prevent future contamination. In some instances, any such requirements may have
been dealt with in the Bankruptcy proceeding.

Employee Safety

We are subject to the requirements of OSHA, as well as to comparable national, state, provincial and local, Canadian, Mexican, U.K. and
European Union laws that are applicable to our Canadian, Mexican and U.K. operations, the purposes of which are to protect the health and safety of workers. In addition, the OSHA hazard communication standard and comparable state, Canadian federal
and provincial statutes require us to organize and disclose information concerning hazardous materials used, produced or transported in our operations. Some of our facilities are subject to the OSHA Process Safety Management regulations that are
designated to prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable or explosive chemicals.

SemCAMS facilities are also subject to regulation by ABSA. SemCAMS maintains its own compliance program, audited by ABSA, which addresses integrity, inspection and process safety management elements as
required by legislation.

Hazardous Materials Transportation Requirements

The DOT regulations affecting pipeline safety require pipeline operators to implement measures designed to reduce the environmental impact
of oil discharge from onshore oil pipelines. These regulations require operators to maintain comprehensive spill response plans, including extensive spill response training for pipeline personnel. In addition, the DOT regulations contain detailed
specifications for pipeline operation and maintenance.

Similar requirements are in effect in Canada.

Anti-Terrorism Measures

The federal Department of Homeland Security Appropriations Act of 2007 requires the Department of Homeland Security (DHS), to issue regulations establishing risk-based performance standards
for the security of chemical and industrial facilities, including oil and gas facilities that are deemed to present high levels of security risk. The DHS issued an interim final rule in April 2007 regarding risk-based performance
standards to be attained pursuant to this act and, on November 20, 2007, further issued an Appendix A to the interim rules that establish chemicals of interest and their respective threshold quantities that will trigger compliance with the
interim rules. To the extent our facilities are subject to existing or new rules, it is possible that the costs to comply with such rules could be substantial.

Title to Properties

Substantially all of our pipelines are constructed on rights-of-way granted by the record owners of the property. Lands over which pipeline rights-of-way have been obtained may be subject to prior liens
that have not been subordinated to the right-of-way grants. We have obtained, where necessary, easement agreements from public authorities and railroad companies to cross over or under, or to lay facilities in or along, watercourses, county roads,
municipal streets, railroad properties and state highways, as applicable. In some cases, property on which our pipeline was built was purchased in fee. Our processing plants and terminals are on real property owned or leased by us.

We believe that we have satisfactory title to all of the assets we own. Although title to such properties is subject to encumbrances in
certain cases, such as customary interests generally retained in connection with acquisition of real property, liens related to environmental liabilities associated with historical operations, liens for current taxes and other burdens and minor
easements, restrictions and other encumbrances to which the underlying properties were subject at the time of acquisition by us, we believe that none of these burdens will materially detract from the value of such properties or from our interest
therein or will materially interfere with their use in the operation of our business.

Office Facilities

In addition to our gathering, storage, terminalling and processing facilities discussed above, we maintain corporate office headquarters
located in Tulsa, Oklahoma. All of the U.S. business segments utilize Tulsa as their center of operations, except for Crude, whose primary operations are located in Oklahoma City. Foreign business segments utilize their centers of operations, which
are Calgary, Alberta for SemCAMS; Puebla, Mexico for SemMexico; and Milford Haven, Wales for SemLogistics. Many of our business segments also have satellite offices located throughout North America. The current lease for our Tulsa headquarters
expires in May 2019, and the other office leases have varying expiration dates. While we may require additional office space as our business expands, we believe that our existing facilities are adequate to meet our needs for the immediate
future, and that additional facilities will be available on commercially reasonable terms as needed.

Employees

As of December 31, 2011, we had approximately 710 employees, including approximately 480 employees outside the U.S. in Canada, Mexico
and the U.K. Approximately 106 of our employees in Canada and Mexico are represented by labor unions and subject to collective bargaining agreements governing their employment with us. Of that number, approximately 55 employees have collective
bargaining agreements that will expire in 2012 and approximately 51 with collective bargaining agreements expiring in 2013. We have never had a labor related work stoppage and believe our employee relations are good.

|Item 1A. | Risk Factors
|-------- | ------------

Our business faces many risks. We believe the risks described below identify the material risks we face. However, the risks described below may not be the only risks we face. Additional unknown risks
or risks that we currently consider immaterial may also impair our business operations. If any of the events or circumstances described below actually occurs, our business, financial condition or results of operations could suffer, and the trading
price of our shares of Class A Common Stock and warrants could decline significantly. Investors should consider the specific risk factors discussed below, together with other information contained in this report on Form 10-K and the other
documents that we will file from time to time with the Securities and Exchange Commission (the SEC).

Risks Related to Our
Business

Our credit facilities require us to maintain certain financial ratios and place other operating and
financial restrictions on us.

Our credit facilities have covenants which require us to satisfy and maintain certain
financial ratios and place certain other restrictions on us. 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. For example, our credit facilities limit our ability to:



| |  |  | incur additional indebtedness;
| | - |  | ------------------------------



| |  |  | incur liens;
| | - |  | ------------



| |  |  | pay dividends over a certain amount;
| | - |  | ------------------------------------



| |  |  | 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.
| | - |  | --------------------------------------------------------------------------------------

Any failure to comply with the restrictions of our credit facilities, or any other such subsequent financing agreements, may result in an
event of default. An event of default may allow the creditors to accelerate the repayment of the related debt, as well as any other debt to which a cross-acceleration or cross-default provision applies. If we are unable to repay amounts outstanding
under our credit facilities when due, the lenders thereunder could, subject to the terms of the relevant agreements, seek to sell or otherwise transfer our assets granted to them as collateral to secure the indebtedness outstanding under those
facilities. Substantially all of our assets have been pledged as collateral to secure our credit facilities. In addition, the lenders under our revolving credit facilities may choose to terminate any commitments they then have made to supply us with
further funds.

Under certain economic conditions, our access to credit markets may be limited, which may adversely
impact our liquidity.

We may require additional capital from outside sources from time to time. Our ability to arrange
financing or renew existing facilities, along with the cost of such capital, is dependent upon a number of variables, including:



| |  |  | general economic, financial and business conditions;
| | - |  | ----------------------------------------------------



| |  |  | industry specific conditions;
| | - |  | -----------------------------



| |  |  | credit availability from banks and other financial institutions;
| | - |  | ----------------------------------------------------------------



| |  |  | investor confidence in us;
| | - |  | --------------------------

| |  |  | competitive, legislative and regulatory matters; and
| | - |  | ----------------------------------------------------



| |  |  | provisions of tax and securities laws that may impact raising capital.
| | - |  | ----------------------------------------------------------------------

In addition, volatility in the capital markets may adversely affect our ability to access any available borrowing capacity under our
revolving credit facilities. Our access to these funds is dependent on the ability of the lenders to meet their funding obligations under these revolving facilities. Lenders may not be able to meet their funding commitments if they experience
shortages of capital and liquidity, resulting in a reduction of our available borrowing capacity.

Our cash flow depends
in part on the available cash and distributions of Rose Rock.

Our partnership interests in Rose Rock are significant
cash-generating assets. Therefore, our cash flow is dependent to some extent upon the ability of Rose Rock to make a minimum quarterly distribution to its unitholders, including us. Rose Rock may not have sufficient available cash from operating
surplus each quarter to enable it to pay the minimum quarterly distribution, which would have a corresponding negative impact on us. The amount of cash Rose Rock can distribute on its units principally depends upon the amount of cash it generates
from its operations, which will fluctuate from quarter to quarter based on, among other things:



| |  |  | the price of crude oil and the level of production of, and demand for, crude oil in the markets it serves;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | the volume of crude oil that it gathers, transports, stores and markets;
| | - |  | ------------------------------------------------------------------------



| |  |  | the fees with respect to volumes that it handles;
| | - |  | -------------------------------------------------



| |  |  | the profitability of its marketing operations;
| | - |  | ----------------------------------------------



| |  |  | damage to pipelines, facilities, related equipment and surrounding properties caused by earthquakes, floods, fires, severe weather, explosions and
other natural disasters and acts of terrorism or inadvertent damage to pipelines from construction, farm and utility equipment;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | leaks or accidental releases of crude oil or other materials into the environment, whether as a result of human error or otherwise;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | demand charges and volumetric fees associated with its transportation services;
| | - |  | -------------------------------------------------------------------------------



| |  |  | the level of competition from other midstream energy companies;
| | - |  | ---------------------------------------------------------------



| |  |  | the level of its operating, maintenance and general and administrative costs;
| | - |  | -----------------------------------------------------------------------------



| |  |  | regulatory action affecting the supply of or demand for crude oil, the rates it can charge, how it contracts for services, its existing contracts, its
operating costs or its operating flexibility;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in tax laws; and
| | - |  | ------------------------



| |  |  | prevailing economic conditions.
| | - |  | -------------------------------

In addition, the actual amount of cash Rose Rock will have available for distribution will depend on other factors, some of which are beyond its control, including:



| |  |  | the level of capital expenditures it makes;
| | - |  | -------------------------------------------



| |  |  | the cost of acquisitions;
| | - |  | -------------------------



| |  |  | its debt service requirements and other liabilities;
| | - |  | ----------------------------------------------------



| |  |  | fluctuations in its working capital needs;
| | - |  | ------------------------------------------



| |  |  | its ability to borrow funds and access capital markets;
| | - |  | -------------------------------------------------------



| |  |  | restrictions contained in debt agreements to which it is a party; and

For further information on the risk factors inherent in the business of Rose Rock, see the other risk factors included in this Form 10-K
that are applicable to Rose Rock and Item 1A. Risk Factors in Rose Rocks Annual Report on Form 10-K.

Our operations could be adversely affected if third-party pipelines or other facilities interconnected to our facilities become
partially or fully unavailable, or if the volumes we gather do not meet the quality requirements of such pipelines or facilities.

Our facilities connect to other pipelines or facilities, some of which are owned by third parties. The continuing operation of such third-party pipelines or facilities is not within our control. These
pipelines and other facilities may become unavailable because of testing, turnarounds, line repair, reduced operating pressure, lack of operating capacity, curtailments of receipt or deliveries due to insufficient capacity, or for any other reason.
If any of these pipelines or facilities becomes unable to transport the products we gather, or if the volumes we gather or transport do not meet the quality requirements of such pipelines or facilities, our results of operations and cash flows could
be adversely affected.

As a public company, we are subject to financial and other reporting and corporate governance
requirements that may be difficult for us to satisfy, will raise our costs, and may divert resources and management attention from operating our business.

Following the effectiveness of our registration statement on Form 10 in November 2010, we are required to file with the SEC annual and quarterly information and other reports that are specified in the
Exchange Act and SEC regulations. Thus, we need to ensure that we maintain the ability to prepare, on a timely basis, reports that comply with SEC requirements. We are also subject to other reporting and corporate governance requirements, including
the listing standards of the NYSE, the provisions of the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act), the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the regulations promulgated thereunder.

The adequacy of our internal control over financial reporting must be assessed by management and audited by an independent registered
public accounting firm each year. If we are unable to maintain adequate internal control over financial reporting or otherwise to comply with Section 404, we may be unable to report financial information on a timely basis, may suffer adverse
regulatory consequences, may have violations of the NYSE listing rules and may breach covenants under our credit facilities. There could also be a negative reaction in the financial markets due to a loss of investor confidence in us and the
reliability of our financial statements.

The changes necessitated by becoming a public company require a significant
commitment of resources and management oversight that increase our costs and may strain our systems and resources. As a result, our managements attention might be diverted from other business concerns. In addition, we might not be totally
successful in maintaining controls and procedures that comply with these requirements. If we fail to maintain an effective internal control environment or to comply fully with the numerous legal and regulatory requirements imposed on public
companies, we could make material errors in, and be required to restate, our financial statements. Any such restatement could result in a loss of public confidence in the reliability of our financial statements and sanctions imposed on us by the
SEC.

Our Comprehensive Risk Management Policys provisions governing our internal trading and marketing activities
cannot eliminate all risks associated with the trading and marketing of commodities, nor can we ensure full compliance at all times with the Comprehensive Risk Management Policy by our employees, both of which could impact our financial and
operational results.

We have in place a Comprehensive Risk Management Policy that establishes authorized commodities
and transaction types, delegations of authority, and limits for trading and marketing exposures and requires that we



29



---

##### Table of Contents

restrict net open positions (e.g., positions that are not fully hedged as to commodity price risk) to specified levels at each of the consolidated and, in certain cases, subsidiary level. Our
risk management policy has restrictive terms with respect to acquiring and holding physical inventory, futures contracts or derivative products for the purpose of proprietary trading activity. These policies and practices, however, cannot eliminate
all risks. If we enter into derivatives contracts or sale contracts for the delivery of products at a future date, we are subject to the risk of non-delivery under product purchase contracts or the failure of gathering and transportation systems.
For example, any event that disrupts our anticipated physical supply of products could create a net open position that would expose us to risk of loss resulting from price changes.

Moreover, we are exposed to price movements on products that are not hedged, including certain of our inventory, such as linefill, which
must be maintained to operate pipeline and gathering lines. We are also exposed to certain price risks that cannot be readily hedged, such as price risks for basis differentials. Basis differentials can be created to the
extent that our purchase or sales contracts call for delivery of a petroleum product of a grade, at a location, or at a time that differs from the specific delivery terms of offsetting purchase and sales agreements or derivative instruments. If this
occurs, we may not be able to use the physical or derivative commodity markets to fully hedge our price risk. Even though we expect to maintain only limited net open positions, as permitted under the Comprehensive Risk Management Policy, we will be
exposed to price risks within predefined limits and authorizations which could impact our operational and financial results.

We also have a risk that employees involved in our trading and marketing operations may not comply at all times with the risk management
policy. Even with management oversight, we cannot ensure with certainty that all violations of the risk management policy, particularly if deception or other intentional misconduct is involved, will be detected prior to our businesses being
materially affected.

Conventional gas operations face increased competitive pressure from shale gas production.

The U.S. Energy Information Administration reports that higher estimates of domestic shale gas resources support
increasing estimates of domestic natural gas production at prices below its previous estimates.

The abundant supply of shale
gas places pressure on all conventional gas production including sour gas production. In addition, facilities designed to remove hydrogen sulfide from a raw gas stream face increased pressure because sour gas is more expensive to process than gas
which does not contain sulfur.

Our construction of new assets is subject to regulatory, environmental, political, legal
and economic risks which could adversely affect our business.

One of the ways we intend to grow our business is
through the construction of new assets. The construction of additions or modifications to our existing systems and of new assets involves numerous regulatory, environmental, political and legal uncertainties beyond our control. In addition, the
construction of additions to our existing gathering and transportation assets may require us to obtain new rights-of-way prior to constructing new pipelines. We may be unable to obtain such rights-of-way to connect new petroleum product supplies to
our existing gathering lines or capitalize on other attractive expansion opportunities. Additionally, it may become more expensive for us to obtain new rights-of-way or to renew existing rights-of-way. If the cost of renewing or obtaining new
rights-of-way increases, or if we lose our existing rights-of-way through our inability to renew right-of-way contracts or otherwise, our results of operations, cash flows and financial condition could be adversely affected.

Actual results may vary significantly from the projections filed with the U.S. Bankruptcy Court.

In connection with our plan of reorganization, we were required to prepare projected financial information to demonstrate to the U.S.
Bankruptcy Court the feasibility of our plan of reorganization and our ability to continue operations upon our emergence from the Bankruptcy. Those projections are included in the Disclosure



30



---

##### Table of Contents

Statement filed with the U.S. Bankruptcy Court on September 25, 2009. Those projections are not included in this report on Form 10-K, are not incorporated by reference into this report on
Form 10-K, and they should not be relied upon. Those projections were based on numerous assumptions about our anticipated future performance and were based on anticipated market and economic conditions that were, and remain, beyond our control or
inconsistent with current strategy. Projections are inherently subject to many uncertainties and a wide variety of significant business, economic and competitive risks. Our actual results of operations and financial condition will vary from those
contemplated by the projections and the variations may be material.

Because our consolidated financial statements
reflect fresh-start reporting adjustments made upon emergence from our Bankruptcy reorganization, and because of the effects of the transactions that became effective pursuant to our plan of reorganization, financial information in our current and
future financial statements will not be comparable to our financial information from prior periods.

In connection with
our Bankruptcy reorganization, we adopted fresh-start reporting effective as of the close of business on November 30, 2009, in accordance with the Financial Accounting Standards board Accounting Standards Codification (ASC) 852,
Reorganizations. Our adoption of fresh-start reporting resulted in our becoming a new entity for financial reporting purposes. As required by fresh-start reporting, our assets and liabilities have been adjusted to reflect fair
value at November 30, 2009. In addition to fresh-start reporting, our financial statements reflect the effects of all of the transactions implemented by our plan of reorganization. Accordingly, our financial statements for periods ending on or
prior to November 30, 2009, are not comparable with our financial statements for periods ending subsequent to November 30, 2009. Furthermore, the estimates and assumptions used to implement fresh-start reporting are inherently subject to
significant uncertainties and contingencies beyond our control. Accordingly, we cannot provide assurance that the estimates, assumptions, and values reflected in our valuations will be realized, and our actual results could vary materially.

An impairment of goodwill could reduce our earnings.

We recorded $188.8 million of goodwill at November 30, 2009, in connection with fresh-start reporting. Goodwill was recorded to
the extent that the Companys reorganization value exceeded amounts attributed to specific tangible or identified intangible assets. Accounting principles generally accepted in the U.S. (GAAP) require us to test goodwill for
impairment on an annual basis, or when events or circumstances occur indicating that goodwill might be impaired. If we were to determine that any of our goodwill was impaired, we would be required to take an immediate charge to earnings.

During 2010 we revised downward our projections of the future earnings potential of the SemCanada Crude segment, following a significant
loss of customers, coupled with a significant decline in profitability and an assessment by a national consultancy that certain market conditions that are adversely impacting this segment were likely to continue. In response to these events, we
tested SemCanada Crudes goodwill and other intangible assets for impairment as of March 31, 2010. Based on the results of these tests, we recorded an impairment loss of $91.8 million, representing the full amount of the goodwill and other
intangible assets attributable to SemCanada Crude. Also during 2010, we sold the property, plant and equipment of the SemCanada Crude segment and began winding down its operations.

Also during 2010, we conducted our annual goodwill impairment test. We concluded that the goodwill attributable to our SemMexico segment
was impaired, due primarily to lower than expected demand for asphalt resulting from a slowdown of road construction in Mexico. We recorded a loss of $8.9 million related to this impairment.

During 2011, we conducted our annual goodwill impairment test, and concluded that the goodwill and other intangible assets related to our
SemStream Arizona business were impaired. We recorded a loss of $9 million related to this impairment. In addition, we concluded that the goodwill related to our SemLogistics business was impaired and, accordingly, recorded an impairment loss of $45
million.

Changes in currency exchange rates could adversely affect our operating results.

A portion of our revenue is generated from our operations in Canada, the U.K. and Mexico, which use the Canadian
dollar, British pound and Mexican peso, respectively, as the functional currency. Therefore, changes in the exchange rate between the U.S. dollar and any of such foreign currencies could adversely affect our financial and operational results.

We are exposed to the creditworthiness and performance of our customers, suppliers and transactional counterparties,
and any material nonpayment or nonperformance by one or more of these parties could adversely affect our financial and operational results.

There can be no assurance we have adequately assessed the creditworthiness of each of our existing or future customers, suppliers or transactional counterparties or that there will not be a rapid or
unanticipated deterioration in their creditworthiness, which may have an adverse impact on our financial condition and results of operations. There is no certainty that our counterparties will perform or adhere to existing or future contractual
arrangements.

We manage our exposure to credit risk through credit analysis and credit monitoring procedures and policies,
including credit support requirements for customers and counterparties to which we extend no or limited unsecured credit, such as letters of credit, prepayments, and guarantees. However, these procedures and policies cannot fully eliminate
counterparty credit risks, and to the extent our procedures and policies prove to be inadequate, our financial and operational results may be negatively impacted.

Some of our counterparties may be highly leveraged or have limited financial resources and will be subject to their own operating and regulatory risks and, even if our credit review and analysis
mechanisms work properly, we may experience financial losses in our dealings with such parties. In addition, volatility in commodity prices might have an impact on many of our counterparties, which, in turn, could have a negative impact on their
ability to meet their obligations to us and may also increase the magnitude of these obligations.

Any material nonpayment or
nonperformance by our counterparties could require us to pursue substitute counterparties for the affected operations, reduce operations or provide alternative services. There can be no assurance that any such efforts would be successful or would
provide similar financial and operational results.

Our business involves many hazards and operational risks, some of
which may not be covered by insurance.

Sudden leaks are possible in operations involving pipelines and tanks. Other
possible operating risks include the breakdown or failure of equipment, information systems or processes; the performance of equipment at levels below those originally intended (whether due to misuse, unexpected degradation or design, construction
or manufacturing defects); failure to maintain adequate inventories of spare parts; operator error; labor disputes; disputes with interconnected facilities and carriers; and catastrophic events such as natural disasters, fires, explosions,
fractures, acts of terrorism and other similar events, many of which are beyond our control.

These risks could result in
substantial losses due to personal injury or loss of life, severe damage to, and destruction of, property and equipment and pollution or other environmental damage, and may result in curtailment or suspension of our related operations. We are not
fully insured against all risks incident to our business. In addition, as a result of market conditions, premiums for our insurance could increase significantly. In some instances, insurance could become unavailable or available only for reduced
amounts of coverage. If a significant accident or event occurs that is not fully insured, it could adversely affect our results of operations, cash flows and financial condition. Even if a significant accident or event is covered by insurance, we
may still have responsibility for applicable deductibles, and in addition, the proceeds of any such insurance may not be paid in a timely manner.

Any acquisition involves risks that may adversely affect our business.

Any acquisition involves potential risks, including:



| |  |  | performance from the acquired businesses or assets that is below the forecasts we used in evaluating the acquisition;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | a significant increase in our indebtedness and working capital requirements;
| | - |  | ----------------------------------------------------------------------------



| |  |  | the inability to timely and effectively integrate the operations of recently acquired businesses or assets;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | the incurrence of substantial unforeseen environmental and other liabilities arising out of the acquired businesses or assets, including liabilities
arising from the operation of the acquired businesses or assets prior to our acquisition;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | risks associated with operating in lines of business that are distinct and separate from our historical operations;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | loss of customers or key employees from the acquired businesses; and
| | - |  | --------------------------------------------------------------------



| |  |  | the diversion of managements attention from other business concerns.
| | - |  | ---------------------------------------------------------------------

Any of these factors could adversely affect our ability to achieve anticipated levels of cash flows from our acquisitions, realize other
anticipated benefits and meet our debt service requirements.

We are subject to the risks of doing business outside of
the U.S.

The success of our business depends, in part, on continued performance in our non-U.S. operations. We
currently have operations in Canada, Mexico and the U.K. In addition to the other risks described in this report on Form 10-K, there are numerous risks and uncertainties that specifically affect our non-U.S. operations. These risks and uncertainties
include political and economic instability, changes in local governmental laws, regulations and policies, including those related to tariffs, investments, taxation, exchange controls, employment regulations and repatriation of earnings, and
enforcement of contract and intellectual property rights. International transactions may also involve increased financial and legal risks due to differing legal systems and customs, including risks of non-compliance with U.S. and local laws
affecting our activities abroad, including compliance with the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act of 2010. While these factors and the impact of these factors are difficult to predict, any one or more of them could adversely
affect our financial and operational results.

We may incur significant costs and liabilities resulting from pipeline
integrity programs and related repairs.

Pursuant to the Pipeline Safety Improvement Act of 2002, as reauthorized and
amended by the Pipeline Inspection, Protection, Enforcement and Safety Act of 2006, the DOT, through the DOTs Pipeline and Hazardous Materials Safety Administration, has adopted regulations requiring pipeline operators to develop integrity
management programs for transmission pipelines located where a leak or rupture could do the most harm in high consequence areas, including high population areas, areas that are sources of drinking water, ecological resource areas that
are unusually sensitive to environmental damage from a pipeline release and commercially navigable waterways, unless the operator effectively demonstrates by risk assessment that the pipeline could not affect the area. The Pipeline Inspection,
Protection, Enforcement and Safety Act of 2006 expired on September 30, 2010, and was operating under the continuing resolution that expired on March 4, 2011. The reauthorization of the Pipeline Safety Act being considered by Congress
could result in new and more costly compliance requirements. Current regulations require operators of covered pipelines to:



| |  |  | perform on-going assessments of pipeline integrity on a recurring frequency schedule;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | identify and characterize applicable potential threats to pipeline segments that could impact a high consequence area;
| | - |  | ----------------------------------------------------------------------------------------------------------------------

| |  |  | improve data collection, integration and analysis;
| | - |  | --------------------------------------------------



| |  |  | repair and remediate the pipeline as necessary; and
| | - |  | ---------------------------------------------------



| |  |  | implement preventive and mitigating actions.
| | - |  | --------------------------------------------

In addition, states have adopted regulations similar to existing DOT regulations for intrastate gathering and transmission lines. We currently estimate that we will incur an aggregate cost of
approximately $2.9 million for years 2011 through 2012 to implement necessary pipeline integrity management program testing along certain segments of our pipelines required by existing DOT and state regulations. This estimate does not include the
costs, if any, of any repair, remediation, preventative or mitigating actions that may be determined to be necessary as a result of the testing program, which costs could be substantial. At this time, we cannot predict the ultimate cost of
compliance with these regulations, as the cost will vary significantly depending on the number and extent of any repairs found to be necessary as a result of the pipeline integrity testing. Following the initial round of testing and repairs, we will
continue our pipeline integrity testing programs on an on-going basis to assess and maintain the integrity of our pipelines. The results of these tests could cause us to incur significant and unanticipated capital and operating expenditures for
repairs or upgrades deemed necessary to ensure the continued safe and reliable operations of our pipelines and, consequently, result in a reduction in our revenue and cash flows from shutting down our pipelines during the pendency of such repairs or
upgrades.

Some of our operations cross the U.S./Canada border and are subject to cross border regulation.

Our cross border activities with our Canadian subsidiaries and certain customers subject us to regulatory matters,
including import and export licenses, tariffs, Canadian and U.S. customs and tax issues and toxic substance certifications. Such regulations include the Short Supply Controls of the Export Administration Act, the North American Free Trade Agreement
and the Toxic Substances Control Act. Violations of these licensing, tariff and tax reporting requirements could result in the imposition of significant administrative, civil and criminal penalties.

We may fail to realize the anticipated benefits from our recent acquisition of a significant equity position in NGL Energy Partners
LP.

On November 1, 2011, SemStream completed the sale of substantially all of its assets to NGL Supply Terminal
Company LLC, a subsidiary of NGL Energy, in exchange for, among other things, 8,932,031 common units (32.2% of the common units outstanding at December 31, 2011) representing limited partnership interests in NGL Energy (the NGL Common
Units). NGL Energy owns and operates a vertically integrated propane business with three operating segments: midstream; wholesale supply and marketing; and retail propane.

We do not control NGL Energys assets and operations and the value of, and benefits from, our investment in the NGL Common Units are
subject to all of the risks and uncertainties inherent in NGL Energys business including, without limitation, the following:



| |  |  | NGL Energy may not have sufficient cash to enable it to pay minimum quarterly distributions on its common units, including the NGL Common Units;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The amount of cash NGL Energy has available for distribution to its unitholders, including us, depends primarily on its cash flow rather than on its
profitability, which may prevent it from making distributions, even during periods in which it realizes net income;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Current conditions in the global capital and credit markets, and general economic pressures, may adversely affect NGL Energys financial position
and results of operations;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Widely fluctuating propane prices could adversely affect NGL Energys ability to finance its working capital needs;
| | - |  | -------------------------------------------------------------------------------------------------------------------

| |  |  | If NGL Energy does not successfully identify acquisition candidates, complete accretive acquisitions on economically acceptable terms, or adequately
integrate the acquired operations into its existing operations, its future financial performance may be adversely affected and its growth may be limited;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Increases in interest rates could adversely impact NGL Energys common unit price, its ability to issue equity or incur debt for acquisitions or
other purposes, and its ability to make cash distributions at its intended levels;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | NGL Energys operations are subject to all the operating hazards and risks incident to handling, storing, transporting, and providing customers
with combustible liquids such as propane;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | NGL Energys partnership agreement limits the fiduciary duties of NGL Energys general partner to NGL Energys unitholders, including
us, and restricts the remedies available to the unitholders for actions taken by its general partner that might otherwise be breaches of fiduciary duty;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cost reimbursements to NGL Energys general partner may be substantial and could reduce its cash available to make quarterly distributions on the
common units, including the NGL Common Units;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | NGL Energys partnership agreement requires that NGL Energy distribute all of its available cash, which could limit its ability to grow and make
acquisitions; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Other factors discussed in NGL Energys Annual Report on Form 10-K and as are included from time to time in NGL Energys public announcements
and other filings with the SEC.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

As part of our transaction with NGL Energy, we waived ordinary course cash
distributions from NGL Energy on 3,932,031 of the NGL Common Units (the Distribution Waiver Units) until August 30, 2012. We may not transfer or sell any of the Distribution Waiver Units prior to September 30, 2012, unless the
purchaser of these units enters into a forbearance agreement with NGL Energy relating to the units purchased. When these restrictions end, to the extent that we desire to sell any of the NGL Common Units, our ability to sell units could be severely
limited, both as to timing and amount, and as a result of factors beyond our control. Also, the market price of the NGL Common Units may decline substantially before we sell the units.

For the reasons described above, we may not realize an adequate return on our investment and we may incur losses on any sales of our
investment.

In addition, our equity in earnings or losses of NGL Energy will be reported in our consolidated statement of
operations, which could result in volatility in our earnings. Future declines in the fair value of our investment in NGL Energy could, under certain circumstances, require us to record impairment losses on our investment.

One of our subsidiaries acts as the general partner of a publicly traded limited partnership, Rose Rock. As such, this
subsidiarys operations may involve a greater risk of liability than ordinary business operations.

One of our
subsidiaries acts as the general partner of Rose Rock, a publicly-traded limited partnership. This subsidiary may be deemed to have undertaken fiduciary obligations with respect to Rose Rock as the general partner and to the limited partners of Rose
Rock. Activities determined to involve fiduciary obligations to other persons or entities typically involve a higher standard of conduct than ordinary business operations and therefore may involve a greater risk of liability, particularly when a
conflict of interests is found to exist. Our control of the general partner of Rose Rock may increase the possibility of claims of breach of fiduciary duties, including claims brought due to conflicts of interest (including conflicts of interest
that may arise between Rose Rock, on the one hand, and its general partner and that general partners affiliates, including us, on the other hand). Any liability resulting from such claims could be material.

A prolonged decline in index prices at Cushing relative to other index prices could reduce the demand for our transportation to,
and storage in, Cushing.

Shifts in the overall supply of, and demand for, crude oil in regional, national and global
markets, over which we have no control, can have an adverse impact on crude oil index prices in the markets we serve relative

##### Table of Contents

to other index prices. For example, Cushing has experienced a shortfall in takeaway pipeline capacity, which has in turn led to an oversupply of crude oil at Cushing. This has been cited as a
principal reason for the decline in the West Texas Intermediate Index (WTI Index) price used at Cushing relative to other crude oil price indexes, including the Brent Crude index. A prolonged decline in the WTI Index price relative to
other index prices may cause reduced demand for our transportation to, and storage in, Cushing, which could have a material adverse effect on our business, results of operations and financial condition.

Adverse developments in our existing areas of operation could adversely impact our results of operations, cash flows and financial
condition.

Our operations are focused on gathering, transporting, storing, processing, and treating petroleum products
utilizing our assets which are principally located in the Midwest and Rocky Mountain supply region of the U.S. and in Alberta, Canada. As a result, our results of operations, cash flows, and financial condition depend upon the demand for our
services in these regions. Due to our current lack of broad diversification in industry type and geographic location, adverse developments in our current segment of the midstream industry, or our existing areas of operation, could have a
significantly greater impact on our results of operations, cash flows, and financial condition than if our operations were more diversified.

The nature and degree of regulation may adversely affect fee structures or operations.

Our operations are subject to substantial regulation from foreign and domestic federal, state, provincial and local authorities. These authorities regulate numerous aspects of our operations, including
our interstate natural gas storage operations, certain crude oil gathering systems, construction and maintenance of facilities, and certain rate structures among other things. We cannot predict the impact of any future revisions or changes in
interpretation of existing laws or regulations or the adoption of new laws and regulations applicable to our businesses. Revisions, interpretation changes or additional regulations could influence our operating environment and may result in
increased costs.

White Cliffs Pipeline is subject to FERC rules and regulations. The FERCs regulatory authority extends
to:



| |  |  | transportation of crude oil in interstate commerce;
| | - |  | ---------------------------------------------------



| |  |  | rates, operating terms and conditions of service;
| | - |  | -------------------------------------------------



| |  |  | accounts and records; and
| | - |  | -------------------------



| |  |  | depreciation and amortization policies.
| | - |  | ---------------------------------------

Regulatory actions in these areas can similarly affect new or expanded pipeline operations.

We may incur significant costs and liabilities in the future resulting from a failure to comply with new or existing environmental laws or regulations or an accidental release of hazardous
substances, petroleum products or wastes into the environment.

Our operations are subject to federal and foreign,
state, provincial and local environmental laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. These laws include, for example:



| |  |  | federal and comparable state and foreign laws that impose obligations related to air emissions;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | federal and comparable state and foreign laws that impose requirements for the handling, storage, treatment or disposal of solid and hazardous waste
from our facilities;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | federal and comparable state and foreign laws that regulate the cleanup of hazardous substances that may have been released at properties currently or
previously owned or operated by us or at locations to which our hazardous substances have been transported for disposal; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



36

##### Table of Contents

| |  |  | federal and comparable state and foreign laws that regulate discharges of wastewater from our facilities require spill protection planning and
preparation and set requirements for other actions for protection of waters.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Failure to comply with these
laws and regulations, or newly adopted laws or regulations, may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of monetary penalties, the imposition of remedial requirements and the issuance of
orders enjoining future operations or imposing additional compliance requirements on such operations. Claims pursued under certain environmental laws impose strict, joint and several liability for costs required to clean up and restore sites where
hazardous substances or petroleum products have been disposed or otherwise released. Provisions also exist that may require remediation or other compensation to pay for damages to natural resources. Moreover, it is not uncommon for individuals to
file claims for personal injury and property damage allegedly caused by the release of hazardous substances, petroleum products or waste products in the environment.

There is an inherent risk of incurring environmental costs and liabilities in connection with our operations due to our handling of crude oil and natural gas, air emissions and water discharges related to
our operations and historical industry operations and waste disposal practices. For example, an accidental release from one of our facilities could subject us to substantial liabilities for environmental cleanup and restoration costs, claims made by
individuals for personal injury, natural resource and property damages and fines or penalties for related violations of environmental laws or regulations. Moreover, the possibility exists that stricter laws, regulations or enforcement policies could
significantly increase our operational or compliance costs and the cost of any remediation that may become necessary. We may not be able to recover all or any of these costs from insurance and fines or penalties paid for compliance violations,
whether alleged or proven, will not be covered by insurance.

Derivatives regulations included in current financial
reform legislation could impede our ability to manage business and financial risks by restricting our use of derivative instruments as hedges against fluctuating commodity prices and interest rates.

In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Act) was passed by Congress and signed into
law. The Act contains significant derivatives regulations, including a requirement that certain transactions be cleared on exchanges and a requirement to post cash collateral (commonly referred to as margin) for such transactions. The
Act provides for a potential exception from these clearing and cash collateral requirements for commercial end-users and includes a number of defined terms that will be used in determining how this exception applies to particular derivative
transactions and the parties to those transactions. The Act requires the Commodity Futures Trading Commission (the CFTC) to promulgate rules to define these terms; however, we neither know the rules the CFTC will promulgate nor the
definitions that will apply to us.

We use crude oil and other energy derivative instruments in connection with our Crude
activities, and may use natural gas related derivative instruments in connection with our SemGas activities, principally to hedge the commodity price risk associated with these businesses. We may also use energy derivatives in conjunction with the
activities of our other businesses and may use interest rate derivative instruments to minimize the impact of interest rate fluctuations associated with our debt. At present, we post collateral with clearing brokers with respect to substantially all
our commitments and potential obligations under these derivative instruments. Depending on the regulations adopted by the CFTC, we may be required to post additional collateral for our energy and interest rate derivative transactions in excess of
present levels. Such a requirement is not anticipated to have a significant impact on our business, but may increase costs and decrease profitability. Moreover, a requirement for our counterparties to post collateral could result in additional costs
being passed on to us, thereby decreasing our profitability.

Our storage operations are influenced by the overall forward market for crude oil,
and certain market conditions may adversely affect our financial and operating results.

Our storage operations are
influenced by the overall forward market for crude oil. A contango market (meaning that the price of crude oil for future delivery is higher than the current price) is associated with greater demand for crude oil storage capacity, because a party
can simultaneously purchase crude oil at current prices for storage and sell at higher prices for future delivery. A backwardated market (meaning that the price of crude oil for future delivery is lower than the current price) is associated with
lower demand for crude oil storage capacity, because a party can capture a premium for prompt delivery of crude oil rather than storing it for future sale. A prolonged backwardated market or other adverse market conditions could have an adverse
impact on our ability to negotiate favorable prices under new or renewing storage contracts, which could have an adverse impact on our storage revenues. Finally, higher absolute levels of crude oil prices increase the costs of financing and insuring
crude oil in storage, which negatively affects storage economics. As a result, the overall forward market for crude oil may have an adverse effect on our business, results of operations, and financial condition.

An increase in interest rates could impact demand for our storage capacity.

There is a financing cost for a storage capacity user to own crude oil while it is stored. That financing cost is impacted by the cost of
capital or interest rate incurred by the storage user in addition to the commodity cost of the crude oil in inventory. Absent other factors, a higher financing cost adversely impacts the economics of storing crude oil for future sale. As a result, a
significant increase in interest rates could adversely affect the demand for our storage capacity independent of other market factors.

We are subject to regulation by multiple governmental agencies, which could adversely impact our business, results of operations and financial condition.

Our business activities are subject to regulation by multiple federal, state and local governmental agencies. Our historical and projected
operating costs reflect the recurring costs resulting from compliance with these regulations, and we do not anticipate material expenditures in excess of these amounts in the absence of future acquisitions, or changes in regulation, or discovery of
existing but unknown compliance issues. Additional proposals and proceedings that affect the midstream industry are regularly considered by Congress, as well as by state legislatures and federal and state regulatory commissions, agencies and courts.
We cannot predict when or whether any such proposals may become effective or the magnitude of the impact changes in laws and regulations may have on our business. However, additions to the regulatory burden on our industry generally increase our
cost of doing business and affect our profitability.

Climate change legislation and related regulatory initiatives
could result in increased operating costs and reduced demand for our services.

In December 2009, the EPA
published its findings that emissions of carbon dioxide, methane and other GHGs present an endangerment to public health and the environment because emissions of such gases are contributing to warming of the earths atmosphere and other
climatic changes. These findings by the EPA allow the agency to proceed with the adoption and implementation of regulations that would restrict emissions of GHGs under existing provisions of the federal Clean Air Act. In anticipation of those
findings, the EPA had previously proposed regulations that would require a reduction in emissions of GHGs from motor vehicles and that could lead to the imposition of GHG emission limitations in Clean Air Act permits for certain stationary sources.
In addition, the EPA issued a final rule, effective in December 2009, requiring the reporting of GHG emissions from specified large GHG emission sources in the U.S., beginning in 2011 for emissions occurring in 2010. In March 2010, the EPA proposed
revisions to these reporting requirements to apply to all oil and gas production, transmission, processing and other facilities exceeding certain emission thresholds. The adoption and implementation of any regulations imposing reporting obligations
on, or limiting emissions of GHGs from, our equipment and operations could require us to incur additional costs to reduce emissions of GHGs associated with

our operations or could adversely affect demand for the petroleum products we gather, treat or otherwise handle in connection with our services.

In March 2011, the U.S. House of Representatives Energy and Power Subcommittee passed the Energy Tax Prevention Act
of 2011 (H.R. 910), which would prevent the EPA from regulating greenhouse gases for the purpose of addressing climate change. However, both President Obama and the Administrator of the EPA have repeatedly indicated their preference for
comprehensive legislation to address this issue and create the framework for a clean energy economy, with the Obama Administration supporting an emission allowance system. Past proposed legislation in Congress has included an economy-wide cap and
trade program to reduce GHG emissions. Although it is not possible at this time to predict how legislation or new regulations that may be adopted to address GHG emissions would impact our business, any such new federal, state or regional
restrictions on emission of CO2that may be imposed in areas
in which we conduct business could also have an adverse effect on our cost of doing business and demand for the petroleum products we gather process, transport, store, distribute and market.

Some states are also looking at similar types of laws and regulations. If one or more states in which our operations are located were to
adopt such laws and implement GHGs programs and/or cap-and-trade programs, we could incur increased operating costs and/or face decreased demand for our services.

Canada does not currently have any federal legislation pending relating to the regulation of GHG emissions. It is widely expected that Canadian federal legislation will be proposed and voted on in
the next couple of years once the U.S. GHG mechanisms are decided. The adoption and implementation of any regulations imposing reporting obligations on, or limiting emissions of GHGs from, our equipment and operations could require us to incur
additional costs to reduce emissions of GHGs associated with our operations or could adversely affect demand for the petroleum products we gather, treat or otherwise handle in connection with our services.

Although Canada has not yet enacted federal GHG legislation, the province of Alberta has set GHG baselines based on 2003-2005 data which
requires a reduction of 12% in GHG emissions intensity from certain facilities, including several of SemCAMS facilities. Beginning with the second half of 2007, penalties are assessed for failure to comply with required reductions. Further
limitations may be imposed in the future which could require additional SemCAMS facilities to have to file annual GHG emissions reports.

The potential increase in the costs of our operations resulting from any legislation or regulation to restrict emissions of GHGs could include new or increased costs to operate and maintain our
facilities, install new emission controls on our facilities, acquire allowances to authorize our GHG emissions, pay any taxes related to our GHG emissions and administer and manage a GHG emissions program. While we may be able to include some or all
of such increased costs in the rates charged by our pipelines or other facilities, such recovery of costs is uncertain. Moreover, incentives to conserve energy or use alternative energy sources could reduce demand for petroleum products, resulting
in a decrease in the demand for our services.

Loss of key employees can significantly reduce capability to execute
strategies.

Much of our future success depends on the continued availability and service of key personnel including
the executive team and skilled employees in technical, operational and staff positions. Experienced personnel in the midstream industry are in high demand and competition for their talents is high. We depend on current and new key officers and
employees to meet the challenges and complexities of our businesses. If any such officers or employees resign, or become unable to continue in their present roles and are not adequately replaced, or if we are unable to fill currently vacant
positions, our business operations could be materially adversely affected. There can be no assurance that we will continue to attract and retain key personnel.

The threat or attack of terrorists aimed at our facilities could adversely affect our
business.

Since the September 11, 2001 terrorist attacks, the U.S. government has issued warnings that energy
assets, specifically the nations pipeline infrastructure, may be future targets of terrorist organizations. These developments have subjected our operations to increased risks. Any future terrorist attack that may target our facilities, those
of our customers or those of certain other pipelines could have a material adverse effect on our businesses. In addition, any governmental body mandated actions to prepare for, or protect against, potential terrorist attacks could require us to
expend money or modify our operations.

We face intense competition in our gathering, transportation, storage and
marketing activities. Competition from other providers of those services that are able to supply our customers with those services at a lower price or on otherwise better terms could adversely affect our business and operating results.

We are subject to competition from other gathering, transportation, storage and marketing operations that may be able
to supply our customers with the same or comparable services at a lower price or otherwise on better terms. We compete with national, regional and local gathering, transportation and storage companies of widely varying sizes, financial resources and
experience, including the major integrated oil companies. Our ability to compete could be harmed by numerous factors, including:



| |  |  | price competition;
| | - |  | ------------------



| |  |  | the perception that another company can provide better service;
| | - |  | ---------------------------------------------------------------



| |  |  | a reluctance to contract with us due to our Bankruptcy filing; and
| | - |  | ------------------------------------------------------------------



| |  |  | the availability of alternative supply points, or supply points located closer to the operations of our customers.
| | - |  | ------------------------------------------------------------------------------------------------------------------

Some of our competitors have greater financial, managerial and other resources than we do, and control substantially more storage or
transportation capacity than we do. Our competitors may expand their assets or operations, creating additional competition for the services we provide to our customers. In addition, our customers may develop their own gathering, transportation and
storage systems or marketing operations in lieu of using ours. Our ability to renew or replace existing contracts with our customers at rates sufficient to maintain current revenues and cash flow could be adversely affected by the activities of our
competitors and our customers.

Our profitability depends on the demand for the products we gather, transport, process
and store in the markets we serve.

Any sustained reduction in demand for petroleum products in markets served by our
midstream assets could result in a significant reduction in the volume of petroleum products that we gather, transport, process and store, thereby adversely affecting our results of operations, cash flows and financial condition. A reduction in
demand can result from a number of factors including:



| |  |  | an increase in the price of products derived from petroleum products;
| | - |  | ---------------------------------------------------------------------



| |  |  | higher taxes, including federal excise taxes, crude oil severance taxes or sales taxes or other governmental or regulatory actions that increase,
directly or indirectly, the cost of petroleum and natural gas based products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | adverse economic conditions which result in lower spending by consumers and businesses on products derived from petroleum products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | higher fuel taxes or other governmental or regulatory actions that increase the cost of the products we handle;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | effects of weather, natural phenomena, terrorism, war, or other similar acts;

Because of the natural decline in production from existing wells in our areas of operation, our success depends on our ability to
obtain new sources of supply of petroleum products, which is dependent on factors beyond our control. Any decrease in the volumes of these products that we gather could adversely affect our business and operating results.

The volumes that support our business are dependent on the level of production from wells connected to our gathering systems, the
production from which may be less than we expect as a result of a natural decline of producing wells over time and the shut-in of wells for economic or other reasons. As a result, our cash flows associated with these wells will also decline over
time. In order to maintain or increase throughput levels on our gathering systems, we must obtain new sources of petroleum products. The primary factors affecting our ability to obtain sources of these products include the level of successful
drilling activity near our systems and our ability to compete for volumes from successful new wells.

We have no control over
the level of drilling activity in our areas of operation, the amount of reserves associated with wells connected to our gathering systems or the rate at which production from a well declines. In addition, we have no control over producers or their
drilling or production decisions, which are affected by, among other things, the availability and cost of capital, prevailing and projected energy prices, demand for petroleum products, levels of reserves, geological considerations, environmental or
other governmental regulations, the availability of drilling permits, the availability of drilling rigs, and other drilling, production and development costs.

Fluctuations in energy prices can also greatly affect the development of new petroleum product reserves and, to a lesser extent, production from existing wells. In general terms, energy prices fluctuate
in response to changes in supply and demand, market uncertainty and a variety of additional factors that are beyond our control. Declines in energy prices could have a negative impact on exploration, development and production activity and, if
sustained, could lead to a material decrease in such activity. Sustained reductions in exploration or production activity in our areas of operation would lead to reduced utilization of our gathering and treating assets. Because of these factors,
even if new reserves are known to exist in areas served by our assets, producers may choose not to develop those reserves. If reductions in drilling activity result in our inability to maintain levels of throughput on our systems, it could have a
material adverse effect on our business, results of operations and financial condition.

Our construction of new assets
may not result in the anticipated revenue increases.

One of the ways we intend to grow our business is through the
construction of new assets. If we undertake such projects, they may not be completed on schedule or at the budgeted cost, or at all. Moreover, our revenue may not increase immediately upon the expenditure of funds on a particular project. For
instance, if we expand a pipeline, the construction may occur over an extended period of time and we will not receive any material increases in revenue until the project is completed. Moreover, we may construct facilities to capture anticipated
future growth in production in a region in which such growth does not materialize. Since we are not engaged in the exploration for, and the development of, natural gas and crude oil reserves, we do not possess reserve expertise and we often do not
have access to third party estimates of potential reserves in an area prior to constructing facilities in such area. To the extent we rely on estimates of future production in our decision to construct additions to our system, such estimates may
prove to be inaccurate because of numerous uncertainties

inherent in estimating quantities of future production. As a result, new facilities may not be able to attract enough throughput to achieve our expected investment return which could adversely
affect our results of operations, cash flows and financial condition.

We may not be able to renew or replace expiring
storage contracts.

We have significant exposure to market risk at the time our existing storage contracts expire and
are subject to renegotiation and renewal. The extension or replacement of existing contracts depends on a number of factors beyond our control, including the:



| |  |  | level of existing and new competition to provide storage services to our markets;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | macroeconomic factors affecting crude oil storage economics for our current and potential customers;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | balance of supply and demand, on a short-term, seasonal and long-term basis, in our markets;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | extent to which the customers in our markets are willing to contract on a long-term basis; and
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | effects of federal, state or local regulations on the contracting practices of our customers.
| | - |  | ---------------------------------------------------------------------------------------------

Any failure to extend or replace a significant portion of our existing contracts, or extend or replace them at comparable rates, could
have a material adverse effect on our business, results of operations, financial condition and Rose Rocks ability to make cash distributions to its unitholders, including us.

A change in the jurisdictional characterization of some of our assets by federal, state or local regulatory agencies or a change in
policy by those agencies could result in increased regulation of our assets, which could affect existing costs and rates.

Interstate transportation and gathering pipelines that do not provide interstate services are not subject to regulation by FERC. However, the distinction between FERC-regulated interstate pipeline
transportation on the one hand, and intrastate pipeline transportation, on the other hand, is a fact-based determination. The classification and regulation of our crude oil pipelines are subject to change based on future determinations by FERC,
federal courts, Congress or regulatory commissions, courts or legislatures in the states in which we operate.

Our Kansas and
Oklahoma gathering pipeline system carries crude oil owned by us and by third parties. We own all of the crude oil shipped on our pipeline system across state lines. We believe that the pipeline segments on which we provide service to third parties
and the services we provide to third parties on the gathering pipeline system meet the traditional tests that FERC has used to determine that the pipeline services provided are not interstate commerce. We believe that the pipeline segments on which
we transport only crude oil owned by us should not be subject to regulation by FERC under the ICA, or that these pipeline segments would qualify for waiver from FERCs regulatory requirements, if applicable. However, we cannot provide assurance
that FERC will not in the future, either at the request of other entities or on its own initiative, determine that some or all of our Kansas and Oklahoma gathering pipeline system and the services we provide on that system are within its
jurisdiction, or that such a determination would not adversely affect our results of operations. If some or all of the gathering system were subject to FERC jurisdiction, and not otherwise exempt from any applicable regulatory requirements, for that
portion of the gathering pipeline system we would be required to file a tariff with FERC, and if our tariff rates were subject to protest, provide a cost justification for the transportation rate subject to protest and provide service to all
potential shippers without undue discrimination. In addition, if the services we provide on any segment(s) of our gathering system become regulated by FERC under the ICA, our services could be subject to a protest and/or complaint before FERC. If
FERC were to determine, in response to a complaint, that our rates are unjust and unreasonable, we could be required to pay reparations and refunds dating to two years before the filing of the complaint. Furthermore, if in the future our services
become subject to state regulation, they could be subject to a protest and/or complaint before a state commission with jurisdiction.

Increased regulation of hydraulic fracturing could result in reductions or delays in
crude oil production in our areas of operation, which could adversely impact our business and results of operations.

An increasing percentage of crude oil production is being developed from unconventional sources such as shale. These reservoirs require
hydraulic fracturing completion processes to release the crude oil from the rock so it can flow through casing to the surface. Hydraulic fracturing involves the injection of water, sand and chemicals under pressure into the formation to stimulate
crude oil production. The EPA has commenced a study of the potential environmental impacts of hydraulic fracturing activities, including on water quality and public health, with results of the study anticipated to be available by late 2012. At the
same time, certain environmental groups have suggested that additional laws may be needed to more closely and uniformly regulate the hydraulic fracturing process, and legislation has been proposed by some members of Congress to provide for such
regulation. For instance, the U.S. Congress is currently considering legislation to amend the federal Safe Drinking Water Act to subject hydraulic fracturing operations to regulation under that act. Sponsors of bills currently pending before the
U.S. Senate and House of Representatives have asserted that chemicals used in the fracturing process could adversely affect drinking water supplies. Proposed legislation would require, among other things, the reporting and public disclosure of
chemicals used in the fracturing process, which could make it easier for third parties opposing the hydraulic fracturing process to initiate legal proceedings against producers and service providers. In addition, these bills, if adopted, could
establish an additional level of regulation and permitting of hydraulic fracturing operations at the federal level, which could lead to operational delays, increased operating and compliance costs and additional regulatory burdens that could make it
more difficult or commercially impracticable to perform hydraulic fracturing, delaying the development of unconventional resources from shale formations which are not commercial without the use of hydraulic fracturing. The Department of Energy, at
the direction of the President, is also studying hydraulic fracturing in order to provide recommendations and identify best practices and other steps to enhance companies safety and environmental performance in their hydraulic fracturing
operations. In addition, several states have already passed, or are considering, legislation that is intended to regulate hydraulic fracturing. We cannot predict what effect such legislation will have on the production of crude oil in our areas of
operation. The imposition of additional regulations and permit requirements could lead to delays or increased operating costs for crude oil producers. A reduction in the production of crude oil in our areas of operation could have an adverse effect
on our business, results of operations and financial condition.

Item 7.Managements Discussion and Analysis of Financial
Condition and Results of Operations

Overview of Business

We provide gathering, transportation, storage, distribution, marketing and other midstream services primarily to independent producers,
refiners of petroleum products and other market participants located in the Midwest and Rocky Mountain regions of the U.S., Canada and the West Coast of 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 between North American production and supply areas, including the Gulf Coast, Rocky Mountain and Western Canadian regions and areas
of high demand such as the Midwest region of the U.S. We maintain and operate storage, terminal and marine facilities at Milford Haven in the U.K. that enable customers to supply products to markets in the Atlantic Basin. We also operate a network
of liquid asphalt cement terminals throughout Mexico.

Our strategically located pipelines, terminals and storage tanks, with
access to North American transportation pipeline interconnects, are well positioned to benefit from the continuing need to transport and gather petroleum products from areas of supply to areas of demand.

How We Evaluate Our Operations

Our management uses a variety of financial and operational metrics to analyze our performance. We view these metrics as important factors in evaluating our profitability and review these measurements on
at least a monthly basis for consistency and trend analysis. These metrics include financial measures such as adjusted gross margin, operating expenses and adjusted EBITDA.

Adjusted Gross Margin

We view adjusted gross margin as an important
performance measure of the core profitability of our operations, as well as 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. We define adjusted gross margin as total revenues minus cost of products sold and unrealized gain (loss) on derivatives. Adjusted gross margin allows us to make a meaningful comparison of the operating results
between our fee-based activities, which do not involve the purchase or sale of petroleum products, and our fixed-margin and marketing operations, which do. In addition, adjusted gross margin allows us to make a meaningful comparison of the results
of our fixed-margin and marketing operations across different commodity price environments because it measures the spread between the product sales price and costs of products sold.

Operating Expenses

Our management seeks to maximize the
profitability of our operations, in part, by minimizing operating expenses. These expenses are comprised of salary and wage expense, utility costs, insurance premiums, taxes and other operating costs, some of which are independent of the volumes we
handle.

The current high levels of crude oil exploration, development and production activities are increasing competition
for personnel and equipment. This increased competition is placing upward pressure on the prices we pay for labor, supplies and miscellaneous equipment. To the extent we are unable to procure necessary services or offset higher costs, our operating
results will be negatively impacted.

Adjusted EBITDA

We define adjusted EBITDA as net income (loss) before interest expense, income tax expense (benefit), depreciation and amortization and adjusted for selected items that SemGroup believes impact the
comparability

of financial results between reporting periods. 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.

Note About Non-GAAP Financial Measures

Adjusted gross margin and adjusted 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.

Operating income (loss) is the GAAP measure most directly comparable to adjusted gross margin, and net income (loss) is the GAAP measure most directly comparable to adjusted 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 gross margin or adjusted EBITDA in isolation or as a substitute for analysis of our results as reported under GAAP. Because adjusted gross margin and
adjusted EBITDA may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Management compensates for the limitations of adjusted gross margin and adjusted EBITDA as an analytical tool by reviewing the comparable
GAAP measures, understanding the difference between adjusted gross margin and adjusted EBITDA, on the one hand, and operating income (loss) and net income (loss), 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.

We operate our business through six primary business segments: Crude, SemStream, SemLogistics, SemCAMS, SemMexico and SemGas. We generate
revenue in these segments by utilizing our assets to provide products and services to third parties and by selectively using our assets to support our marketing activities. For certain products, the relationship between current and future price is
generally seasonal. We believe that the variety of our petroleum product assets creates opportunities for us and our customers year round.

Certain factors are key to our operations. These include the safe, reliable and efficient operation of the pipelines and facilities that we own and operate while meeting the regulations that govern the
operation of our assets and the costs associated with such regulations. Our revenue is impacted by several factors, including:

Throughput and processing fees

Throughput and processing fees are fees charged to third parties based on volumes of product run through our processing facilities or pipeline gathering systems.

Service, Storage and Terminalling Fees

Storage and terminalling fees are fees charged to third parties for petroleum product storage or terminalling services provided by us and are based on leased shell capacity and/or volumes moved through
our terminal facilities.

Tariffs

Tariffs are fees charged to third parties for the transportation of their petroleum products on our regulated White Cliffs Pipeline.

Petroleum Product Marketing

We intend to capture the normalized
gross margin associated with the purchase and sale of petroleum products. Purchases, sales and derivative transactions related to this activity are tracked in our systems to the ultimate realization of profit. We seek to maintain limited
net open positions to manage our exposure to commodity prices. Marketing transactions may only be entered into by persons delegated such authority by senior management, as provided in our Comprehensive Risk Management Policy. Each person authorized
to make transactions is subject to internal volume and dollar limits, portfolios are subject to net open position and stop loss limits, and counterparties are subject to credit limits and provisions as approved by our credit department. See
BusinessRisk Governance and Comprehensive Risk Management Policy for more information on our Comprehensive Risk Management Policy.

Revenue

Our revenue is generated from third-party fees earned through the
gathering, pipeline transporting and storing of petroleum products principally in the Midwest region. Our customers pay us fees based on volumes gathered, transported and stored; through the sale of petroleum products based upon contract or index
rates per barrel, million Btu or gallon. We generate additional revenue through selected marketing of petroleum products. Marketing operations consist primarily of aggregating petroleum products purchased at the lease along pipeline systems or
trucked, and arranging the necessary transportation logistics for the ultimate sale or delivery of the petroleum products to customers or other end-users. Gathering and transportation revenue is recognized as petroleum products are delivered to
customers. Storage revenue is recognized upon leasing of shell capacity on a take or pay basis. Marketing revenue is accrued at the time title to the petroleum product sold transfers to the purchaser, which typically occurs upon receipt of the
petroleum product by the purchaser.

We utilize futures, swaps and options contracts to manage our exposure to market changes
in commodity prices, to protect our gross margins on our purchased petroleum products and to manage our liquidity risk

associated with margin deposit requirements on our overall derivative positions. When purchasing petroleum products, we seek to manage our exposure to commodity price risk. As we
purchase inventory from suppliers, we may establish a fixed or variable margin with future sales utilizing one of the following methods:



| |  |  | we have already sold that product for physical delivery pursuant to sales contracts at a market index price,
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | we sell the product for future physical delivery pursuant to effectively back-to-back sales contracts, or
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | we enter into futures and swaps contracts on the NYMEX or over the counter (OTC) markets.
| | - |  | -------------------------------------------------------------------------------------------

In addition, we may purchase put options or derivatives other than futures or swaps to hedge our inventory of petroleum products prior to
our sale of such inventory.

ASC 845-10-15, Nonmonetary Transactions, requires certain transactions 
those where inventory is purchased from a customer then resold to the same customers  to be presented in the income statement on a net basis, resulting in a reduction of revenue and costs of products sold by the same amount, but has no effect
on operating income (loss). However, changes in the level of such purchase and sale activity between periods can have an effect on the comparison between those periods.

Volumes

Generally, we expect revenue to increase or decrease in
conjunction with increases or decreases in total volumes. Our total volumes are affected by different factors including our physical storage or transportation capacity, our working capital and credit availability under our credit facilities to
support petroleum product purchases and the availability of the supply of petroleum product available for purchase, which is determined based primarily upon producer activity in market areas contiguous with our asset base.

Commodity Prices

Our business is primarily fee based. As a result, our financial results are typically not correlated with increases and decreases in
commodity prices. Our financial results, however, are positively correlated with the absolute difference between current (prompt) and future month petroleum product prices. That is, wide contango (when the prices for future deliveries are higher
than current prices) spreads generally have a favorable impact on our results relative to a slightly contango, flat market, or backwardated (when the prices for future deliveries are lower than current prices).

Timing of Purchase and Sales

Our financial results are affected by the timing of the purchase and sale of petroleum products, such that financial results may not be comparable between periods. When we enter into an arrangement to
purchase product, place the product in storage and resell the product in the future, our financial results do not reflect any related margin until the settlement of the product sale. Prior to the settlement of the product sale, our results reflect
the cost of the product in our inventory. Differences in the timing of our product purchases and sales, especially if they extend over fiscal years or quarters, may result in sizeable differences between our results over the comparable period.

Analysis of Business Segments

The following provides an overview of the makeup of revenue at each of our respective business segments.

Crude

Rose Rock was formed in August 2011. In November 2011,
SemGroup contributed SemCrude, L.P. to Rose Rock in exchange for limited partner interests, general partner interests and certain incentive distribution rights.

##### Table of Contents

In December 2011, Rose Rock completed an initial public offering in which it sold 7,000,000 common units representing limited partner interests. SemGroup consolidates the accounts of Rose Rock as
a result of the level of its ownership interests and control over the entity.

Crude conducts business through its 51%
ownership interest in White Cliffs Pipeline (which it operates) and a 2% general partner interest and 57.0% limited partner interest in Rose Rock. These operations include crude oil transportation, storage, terminalling, gathering and marketing in
Colorado, Kansas, Montana, North Dakota, Oklahoma and Texas, for third party customers as well as for itself. The Crude business unit consists of three primary operations: (i) Kansas and Oklahoma pipeline system (Rose Rock); (ii) Cushing
storage (Rose Rock); and (iii) White Cliffs Pipeline. A majority of Crudes revenue is generated from fee-based contractual arrangements that, in some instances, are fixed and not dependent on usage.

Fee-Based Services

Crude charges a capacity or volume-based fee for the unloading, transportation and storage of crude oil and related ancillary services. Crudes fee-based services include substantially all of its
operations in Cushing and Platteville and a portion of the transportation services it provides on its Kansas and Oklahoma pipeline system. Some of Crudes fee-based contracts are take-or-pay contracts whereby the customer is required to pay
Crude a fixed minimum monthly fee regardless of usage. For the years ended December 31, 2011 and 2010, approximately 56% and 80% of Crudes adjusted gross margin, respectively, was generated by providing fee-based services to customers.

Fixed-Margin Transactions

Crude purchases crude oil from a producer or supplier at a designated receipt point at an index price less a transportation fee, and simultaneously sells an identical volume of crude oil at a designated
delivery point to the same party at the same index price, thereby locking in a fixed margin that is in effect economically equivalent to a transportation fee. We refer to these arrangements as fixed-margin or buy/sell
transactions. These fixed-margin transactions account for a portion of the adjusted gross margin Crude generates on its Kansas and Oklahoma pipeline system and through its Bakken Shale operations. For the years ended December 31, 2011 and 2010,
approximately 14% and 5% of its adjusted gross margin, respectively, was generated through fixed-margin transactions.

Marketing Activities

Crude conducts marketing activities by purchasing crude oil for its own account from producers, aggregators and traders and selling crude oil to traders and refiners. Crudes marketing activities
account for a portion of the adjusted gross margin it generates on its Kansas and Oklahoma pipeline system and through its Bakken Shale operations. For the years ended December 31, 2011 and 2010, approximately 30% and 15% of its adjusted gross
margin, respectively, was generated through marketing activities.

We mitigate the commodity price exposure of our crude oil
marketing operations by limiting our net open positions through (i) the concurrent purchase and sale of like quantities of crude oil to create back-to-back transactions intended to lock in positive margins based on the timing,
location or quality of the crude oil purchased and delivered or (ii) derivative contracts. All of our marketing activities are subject to our comprehensive risk management policy, which establishes limits to manage risk and mitigate financial
exposure.

More specifically, we utilize futures and swap contracts to manage our exposure to market changes in commodity
prices, to protect our adjusted gross margin on our purchased crude oil and to manage our liquidity risk associated with margin deposit requirements on our overall derivative positions. As we purchase inventory from suppliers, we may establish a
fixed or variable margin with future sales by:



| |  |  | selling a like quantity of crude oil for future physical delivery to create an effective back-to-back transaction; or
| | - |  | ---------------------------------------------------------------------------------------------------------------------

SemStream

On
November 1, 2011, SemStream contributed the primary operating assets of this business segment to NGL Energy in exchange for cash and equity interests. As part of this transaction, we agreed to waive our distribution rights on certain units
until the third quarter of 2012. In exchange, we received additional common units. We own 32.2% of the common units outstanding at December 31, 2011, 7.5% of NGL Energys general partner and exercise significant influence through two
general partner board seats. As a result, we account for our ownership as an investment using the equity method. Going forward, we will include our share of NGL Energy earnings on a one quarter lag because we will not receive their financial
statements in sufficient time to apply the equity method currently. SemStream holds SemGroups ownership interest in NGL Energy, a company engaged in coast-to-coast retail propane operations as well as midstream terminal operations.

SemStream also, through its wholly-owned subsidiary, SemStream Arizona Propane, L.L.C. (SemStream Arizona), is engaged in
retail sales and downstream distribution of propane in Page and Payson, Arizona, including a regulated underground utility business and a non-regulated propane bulk business.

SemLogistics

SemLogistics owns the largest independent petroleum
products storage facility in the U.K. The facility is located on the north bank of the Milford Haven Waterway on the west coast of Wales. The main activities of SemLogistics are the receipt, storage and redelivery of clean petroleum and crude oil
products via sea-going vessels at the Milford Haven site. SemLogistics revenue is based on fixed-fee storage tank leases and related services.

SemCAMS

SemCAMS operates majority-owned gathering assets and
natural gas processing plants. We acquired the Canadian natural gas processing and gathering operations of Central Alberta Midstream, or CAMS, in March 2005. All of SemCAMS assets are located in West-Central Alberta, in the heart of the
Western Canadian Sedimentary Basin, which accounts for approximately 80% of Canadas sour natural gas production. SemCAMS revenue is based on fee-based throughput arrangements and profit sharing from plant operations.

SemMexico

SemMexico operates a network of liquid asphalt terminals in Mexico. Operations include purchasing, producing, storing and distributing
liquid asphalt cement products. SemMexico purchases asphalt from local refineries in Mexico. SemMexicos revenue is based on margin from contractual arrangements with customers and suppliers for liquid asphalt cement. In general,
SemMexicos sales and purchases of liquid asphalt cement are matched and SemMexico carries limited exposure to price movements.

SemGas

SemGas
provides gathering, processing and storage services to the natural gas markets in the U.S. SemGas owns and operates gathering systems and processing plants in Kansas, Oklahoma and Texas. SemGas aggregates gas supplies from the wellhead and provides
various services to producers that condition the wellhead gas production for downstream markets. SemGas performance is largely based on percent-of-proceeds and percent-of-index contractual arrangements where SemGas receives a portion of
product sales as well as fee-based gathering service payments.

We previously had another business segment, SemCanada Crude,
which aggregated and blended crude oil in Western Canada, North Dakota and Montana. During 2010, we transferred certain of SemCanada Crudes activities to Crude and we began winding down the remaining operations of SemCanada Crude.

Results of Operations

Overview

On July 22, 2008, SemGroup, L.P. and certain of its
U.S. subsidiaries filed petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code (the Petition Date). Also on July 22, 2008, SemGroup, L.P.s Canadian subsidiaries filed applications for creditor protection
under the Companies Creditors Arrangement Act. Later during 2008, certain other U.S. subsidiaries filed petitions for reorganization. While under bankruptcy protection, SemGroup, L.P. sold or liquidated certain of its subsidiaries. All
remaining subsidiaries emerged from the Bankruptcy on November 30, 2009 (the Emergence Date). We emerged as a newly reorganized company named SemGroup Corporation.

We lost control of several of our subsidiaries as a direct, or indirect, result of the Bankruptcy petitions, including all Canadian
subsidiaries, SemGroup Holdings, L.P. (which directly held our limited partnership interests in Blueknight Energy Partners, L.P., formerly SemGroup Energy Partners, L.P., and indirectly held our general partnership interests in Blueknight), and
Wyckoff Gas Storage Company, LLC (Wyckoff). These subsidiaries were de-consolidated during 2008 and subsequently accounted for as cost method investments, and not included in results of operations subsequent to deconsolidation. We
regained control of SemCAMS and SemCanada Crude on the Emergence Date, and consolidated these subsidiaries again beginning on that date. We ceased operations of SemCanada Energy near the time of the bankruptcy filing in July 2008.

As part of the process of reorganizing to emerge from bankruptcy protection, we determined the need to dispose of certain operations.
SemFuel, SemMaterials and SemEuro Supply met the criteria to be classified as discontinued operations.

We applied fresh-start
reporting on November 30, 2009. We recorded individual assets and liabilities based on their fair values at November 30, 2009, using the assistance of a valuation advisor to determine the values of certain assets. We adjusted deferred tax
liabilities, where appropriate, to reflect the change in the financial reporting basis of assets.

As a result of these
factors (the Bankruptcy, deconsolidation and reconsolidation of certain subsidiaries, sale of subsidiary assets and fresh-start reporting) and other factors, comparison of the results of operations between 2009 and 2010 shown below is not useful as
a guide to future results of operations. The financial performance for the first 11 months of 2009 are presented for historical perspective and do not give pro forma results as if the consummation of the plan of reorganization and the related
fresh-start reporting and other adjustments had occurred at the beginning of the period presented. Additionally, our post-emergence financial statements are not comparable with our pre-emergence financial statements.

Recent Developments

On February 21, 2012, SemGroup, Gavilon Midstream Energy, LLC, a subsidiary of The Gavilon Group, LLC, and an affiliate of Chesapeake Energy Corporation (NYSE:CHK) announced plans to form a joint
venture that will construct a 210-mile pipeline in western and north central Oklahoma which will deliver crude oil to a 1-million-barrel storage facility in Cushing, Oklahoma. The pipeline and storage facility will meet growing midstream
requirements resulting from the burgeoning drilling activity in western Oklahoma and the Mississippi Lime play.

The pipeline
will consist of two laterals, one originating near the town of Alva in Woods County, Oklahoma, and the other near the town of Arnett in Ellis County, Oklahoma. The laterals will intersect near Cleo Springs in Major County, Oklahoma, where the
pipeline will increase in diameter and continue east to storage at Cushing. The pipeline will have an initial capacity of 140,000 barrels per day, and following the addition of more horsepower, a maximum operating capacity of 180,000 barrels per
day. Construction of the pipeline is planned to begin in July 2012, and it is expected to be in service in the third quarter of 2013.

Revenue and expenses

Revenue and expenses are analyzed by operating segment below.

General and administrative
expenses

For the eleven months ended November 30, 2009, corporate general and administrative expenses were
allocated to the segments based on percentages established by SemGroup management. At the beginning of each year, management estimated corporate general and administrative costs and assigned the segments a flat monthly charge of that amount. From
time to time, the monthly charges were reviewed and adjusted. In addition to the flat monthly charge, the segments would also be allocated a portion of the over or under allocation of actual corporate general and administrative expense from the
prior month. This monthly true up was based on each segments year to date allocation as a percentage of the total year to date corporate general and administrative expense.

Beginning in December 2009, the general and administrative expenses of each corporate department has been allocated to the segments based
on criteria such as actual usage, headcount and estimates of effort or benefit. The method for allocating cost is based on the type of service being provided. For example, internal audit costs are based on an estimate of effort attributable to a
segment. In contrast, accounting department costs are allocated based on the number of transactions processed for a given segment compared to the total number processed.

##### Table of Contents

During bankruptcy, certain costs related to the reorganization and governance of the
Company were classified as reorganization items; however, after emergence such costs were classified as general and administrative.

Interest expense

Interest expense decreased in 2011 to $60 million from $86 million in 2010. About $12 million of this decrease is attributable to the
refinancing of a credit facility in June of 2011 and the repayment of two term loans in the fourth quarter of 2011. An additional $11 million of the decrease is attributable to the repayment of a term loan in September 2010. Finally, $2 million of
the decrease relates to the refinancing of a credit facility in December 2010.

During the time we were in bankruptcy, we
recorded interest expense only to the extent such interest was expected to be paid. Interest obligations that were expected to be compromised in the reorganization process were not recorded as expenses. The total amount of interest that we would
have been contractually obligated to pay, but which was compromised in the reorganization process and not recorded as an expense, was $221 million for the period January 1, 2009 through November 30, 2009.

Other expense (income)

The net of other expense (income) changed in 2011 to income of $15 million from expense of $4 million in 2010. This is primarily the result of changes in foreign exchange rates ($6 million), a decline in
the fair value of outstanding warrants ($5 million), insurance recoveries ($2 million) and the absence of a 2010 expense item ($5 million) in 2011.

Reorganization gain

Reorganization gain includes revenue, expenses,
realized gains and losses and provisions for losses resulting from the reorganization and restructuring of the business. The reorganization gain of $3,532 million in the eleven months ended November 30, 2009 is primarily composed of
$2,544 million gain on extinguishment of debt, $614 million gain on the disposal of Blueknight and $353 million gain on asset revaluation in fresh-start reporting.

Discontinued operations

SemMaterials, SemFuel and SemEuro Supply
are presented as discontinued operations. During 2008, we decided to sell the assets of SemMaterials and to cease the operations of SemEuro Supply, due to their losses from operations and working capital requirements. During 2009, we decided to sell
the assets of SemFuel due to its working capital requirements. By December 31, 2009, the majority of the assets of SemMaterials and SemFuel had been sold.

Product revenue increased in 2011 to $1,084 million from $560 million in 2010. The increase was primarily
due to an increase in the volume sold to 11.6 million barrels at an average sales price of $94 per barrel in 2011 from 7.0 million barrels at an average sales price of $79 per barrel in 2010.

The increase in sales volume was primarily the result of an increase in buy/sell transactions (as defined above) to 6.8 million
barrels in 2011 compared to 1.4 million barrels in 2010. The buy/sell transactions are used to achieve a transportation margin. The increase in buy/sell activity was offset, in part, by a decrease of 1.0 million barrels of marketing
activity.

Revenue was reduced by $689 million in 2011 and $397 million in 2010, in accordance with ASC 845-10-15.

Service revenue decreased to $36 million in 2011 from $84 million in 2010. Of this decrease $36 million relates to the fact that White
Cliffs Pipeline was consolidated until the end of September 2010, but has been

accounted for under the equity method since then. (See Note 5 to our consolidated financial statements in this Form 10-K for additional information related to White Cliffs Pipeline.) In addition,
transportation revenue decreased $6.5 million in 2011 compared to 2010. This decrease reflects increased use of buy/sell transactions (as described above) to achieve transportation margin and the completion of a take-or-pay contract. Also, storage
revenue decreased $5.1 million in 2011 from 2010 as a result of a decrease in storage rates to levels which are expected to continue until 2015.

Costs of products sold

Costs of products sold increased in 2011 to
$366 million from $149 million in 2010. Costs of products sold were reduced by $689 million and $397 million in 2011 and 2010, respectively, in accordance with ASC 845-10-15. Costs of products sold increased in 2011 as a result of an increase in the
average cost of crude oil per barrel to $91 from $77 in 2010 and an increase in the volume sold to 11.6 million barrels in 2011 from 7.0 million barrels in 2010.

Adjusted gross margin

Adjusted gross margin in this segment is generated
by providing fee-based services, by entering into fixed-margin transactions and through marketing activities. Revenues from fee-based services are included in service revenue, and revenues from fixed-margin and marketing activities are included in
product revenue.

The following table shows the adjusted gross margin generated by this segments fee-based services,
fixed-margin transactions and marketing activities for the year ended December 31, 2011:

Operating expense

Operating expense decreased in 2011 to $17 million from $25 million in 2010. Of this decrease, $6.3 million related to operating expenses of White Cliffs Pipeline, which was a consolidated subsidiary
until September 2010 after which it was accounted for under the equity method. An additional $6.0 million of the decrease is attributable to a $3.3 million 2010 bad debt expense of which $2.7 million was recovered in 2011.

Depreciation and amortization

Depreciation and amortization expenses decreased in 2011 to $11 million from $28 million in 2010. This decrease relates to expenses of White Cliffs Pipeline which was a consolidated subsidiary until
September 2010 after which it was accounted for under the equity method.

Loss on disposal or impairment

We sold a portion of our ownership interests in White Cliffs during September 2010 and received $141 million of
proceeds from these transactions. Upon closing, we deconsolidated White Cliffs and recorded our investment at fair value, which approximated 51% of the net book value of White Cliffs (the book value of White Cliffs had been adjusted to fair value on
November 30, 2009, in connection with fresh-start reporting). We recorded a loss of $6.8 million upon conversion to the equity method.

Earnings from equity method investment

Crudes only equity
method investment is in White Cliffs. Prior to the end of September 2010, we consolidated White Cliffs; after September 2010, we account for our investment in White Cliffs under the equity method.

Product revenue increased in 2010 to $560 million from $384 million as a result of an increase in sales
volume to 7.1 million barrels from 6.7 million barrels and an increase in the average sales price to $79 per barrel from $54 per barrel.

Revenue was reduced by $397 million and $187 million in 2010 and the eleven months ended November 30, 2009, respectively, in accordance with ASC 845-10-15.

Costs of products sold

Costs of products sold decreased in 2010 to $149 million from $179 million in the eleven months ended November 30, 2009. Costs of products sold were reduced by $397 million and $187 million in 2010
and the eleven months ended November 30, 2009, respectively, in accordance with ASC 845-10-15. Except for this reduction, costs of products sold increased in 2010 primarily as a result of an increase in the average cost of crude oil per barrel
to $77 from $52 per barrel in 2009.

Operating expense

Operating expense increased in 2010 to $25 million from $18 million in the eleven months ended November 30, 2009. The increase is due
primarily to $4 million in expenses related to White Cliffs Pipeline, which became operational in June 2009, and bad debt expense of $3 million related to a customer that declared bankruptcy.

General and administrative expense

General and administrative expense increased in 2010 to $11 million from $7 million in the eleven months ended November 30, 2009. Approximately $3 million of this increase is due to an allocation of
corporate overhead to White Cliffs Pipeline, which was not made in the first half of 2009. The remainder of the increase is due primarily to incentive compensation and restricted stock expense.

Depreciation and amortization

Depreciation and amortization expense increased in 2010 to $28 million from $11 million in the eleven months ended November 30, 2009. This increase is due primarily to higher depreciation as a result
of higher fixed asset values which were recorded as part of fresh-start reporting. In addition, the increase also includes the amortization of intangible assets which were recorded as part of fresh-start reporting.

Loss on disposal or impairment

We sold a portion of our ownership interests in White Cliffs during September 2010. We received $141 million of proceeds from these transactions, which were used to retire the SemCrude Pipeline credit
facility and

to make payments on our revolving credit facility and term loan. Upon closing, we deconsolidated White Cliffs and recorded our investment at fair value, which approximated 51% of the net book
value of White Cliffs (the book value of White Cliffs had been adjusted to fair value on November 30, 2009, in connection with fresh-start reporting).

We recorded our investment in White Cliffs at fair value at the date of deconsolidation. We recorded a loss of $6.8 million upon conversion to the equity method, which is included within loss on disposal
or impairment of long-lived assets.

Equity earnings

At the end of September 2010, we sold a portion of our ownership interests in White Cliffs to two unaffiliated parties. Upon closing of
this sale, the other owners received substantive rights to participate in the management of White Cliffs. Because of this, we deconsolidated White Cliffs at the end of September 2010, and began accounting for it under the equity method. The equity
in earnings of White Cliffs for the three months ended December 31, 2010 was $1.9 million.

December 2009 versus
average of Eleven Months ended November 30, 2009

General

The Company desires to provide a meaningful comparison of the Results of Operations of the Successor (December 2009) to that of the
Predecessor (eleven months ended November 30, 2009). In order to make this comparison as useful as possible, we have based the comparison on the average of the eleven months ended November 30, 2009. In this way, any significant changes
from the average can be identified and become the subject of explanation.

Revenue

Revenue in December 2009 is approximately 40 percent less than the average of the eleven months ended November 30, 2009, primarily
because certain marketing activity that occurred in the first ten months of 2009 did not occur in December. The marketing activity stopped in October 2009 because of the Companys assessment of the spread between current prices and forward
prices for crude oil.

Costs of products sold

Costs of products sold in December 2009 is approximately 60 percent less than the average of the eleven months ended November 30,
2009, because certain marketing activity that occurred in the first ten months of 2009 did not occur in December. This percentage decline is higher than what is shown in the Revenue explanation above because the marketing activity has a significant
costs of products sold component in contrast to transportation or storage revenue, which do not.

Operating expense

Operating expense in December 2009 is approximately 44 percent lower than the average of the eleven months ended
November 30, 2009, primarily because of an adjustment to property tax expense recorded in December.

General and
administrative expense

General and administrative expense in December 2009 is approximately three times the average of
the eleven months ended November 30, 2009. During bankruptcy, certain costs related to the reorganization and governance of the Company were classified as reorganization items; however, after emergence such costs were classified as general and
administrative expenses.

Depreciation and amortization

Depreciation and amortization in December 2009 is approximately five times the average of the eleven months ended November 30, 2009.
This increase is due primarily to the amortization of intangible assets recorded as part of fresh-start reporting. In addition, the increase reflects higher depreciation as a result of higher fixed asset values which also were recorded as part of
fresh-start reporting

SemStream

On November 1, 2011, we contributed the primary operating assets of our SemStream segment to NGL Energy. The assets we contributed included the majority of SemStreams inventory, derivative
assets, other current assets, property, plant, and equipment, goodwill, other intangible assets, and other noncurrent assets. As part of this transaction, NGL Energy assumed certain liabilities of the SemStream segment including its derivative
liabilities. We did not contribute any of the assets or liabilities of SemStreams Arizona residential business to NGL Energy.

In return for this contribution, we received the following:



| |  |  | 8.9 million common units of NGL Energy (32.2% of the common units outstanding at December 31, 2011);
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | a 7.5% interest in NGL Energy Holdings LLC, the general partner of NGL Energy;
| | - |  | ------------------------------------------------------------------------------



| |  |  | a cash payment of $93 million subject to post-closing adjustments; and
| | - |  | ----------------------------------------------------------------------



| |  |  | two seats on the board of directors of NGL Energy Holdings LLC
| | - |  | --------------------------------------------------------------

Also, as part of this transaction, we agreed to waive our distribution rights on approximately 3.9 million units until the third
quarter of 2012. In exchange, we received an additional 204,000 common units. We estimate that the fair value of the ownership interests in NGL Energy that we received in this transaction was approximately $184 million at November 1, 2011. The
cash proceeds we received were subject to post-closing adjustments. Those adjustments have been completed and we have recorded a gain on this transaction of $44.3 million.

Results of operations for 2011 include no earnings from our equity method investment in NGL Energy. Going forward, we will include our share of NGL Energys earnings on a one quarter lag because we
will not receive their financial statements in sufficient time to apply the equity method to the current period. As a result of this transaction, analysis of the 2011 operating results compared to 2010 is of no value in assessing the future
prospects of this business unit.

Product revenue decreased in 2011 to $747 million from $844 million in 2010. The effect of lower volume
(506 million gallons versus 656 million gallons) was only partially offset by higher prices ($1.48 per gallon versus $1.29 per gallon). The decrease in volume reflects the timing of the NGL Energy transaction described above, which reduced the
length of the period in which certain sales were made by two months compared to the prior year.

Revenue was reduced by $128
million and $119 million during 2011 and 2010, respectively, in accordance with ASC 845-10-15.

We recorded $11 million in
realized losses on derivatives in 2011 compared to $24 million of such losses in 2010. There was less derivative activity during 2011 in anticipation of the NGL Energy transaction described above.

Costs of products sold

Costs of products sold decreased in 2011 to $605 million from $691 million in 2010. The decrease is primarily a result of a decline in volume between the periods. The decrease in volume is a result of the
NGL transaction described above. Costs of products sold were reduced by $128 million and $119 million in 2011 and 2010, respectively, in accordance with ASC 845-10-15.

Gain on disposal or impairment

The gain on disposal or impairment
of $36 million recorded in 2011 is the net of $44.3 million gain on the disposal of SemStream assets in the NGL Energy transaction, offset, in part, by a $9 million impairment of goodwill and other intangible assets of SemStreams Arizona
residential propane business. (The Arizona residential propane business was not contributed to NGL Energy.)

Equity
earnings

As mentioned above, we record our equity in earnings or losses of NGL Energy on a one-quarter lag. Because of
this, we have not recorded any equity in earnings or losses of NGL Energy during 2011 (our ownership interests in NGL Energy were acquired on November 1, 2011).

Product revenue increased in 2010 to $844 million from $469 million. Approximately 53 percent of the
increase is due to volume and approximately 47 percent of the increase is due to higher sales prices.

Revenue was reduced by
$119 million and $10 million in 2010 and the eleven months ended November 30, 2009, respectively, in accordance with ASC 845-10-15.

Costs of products sold

Costs of products sold increased in 2010 to
$691 million from $425 million in the eleven months ended November 30, 2009. Costs of products sold were reduced by $119 million and $10 million in 2010 and the eleven months ended November 30, 2009, respectively, in accordance with ASC
845-10-15. The increase in the costs of products sold is primarily a result of increased volume and higher product prices.

General and administrative expense

General and administrative expense increased in 2010 to $10 million from $5 million in the eleven months ended November 30, 2009. This increase is primarily the result of an increase in corporate
overhead allocated to this reporting segment. The amount of corporate overhead allocated to this reporting segment increased because during bankruptcy certain costs related to the reorganization and governance of the Company were classified as
reorganization items; however, after emergence such costs were classified as general and administrative expense. In addition, a portion of the increase is due to incentive compensation and restricted stock expense.

Depreciation and amortization

Depreciation and amortization increased in 2010 to $7 million from $5 million in the eleven months ended November 30, 2009. This increase is due primarily to the amortization of intangible assets
recorded as part of fresh-start reporting.

December 2009 versus average of Eleven Months ended November 30, 2009

Revenue

Revenue in December 2009 is approximately 64 percent higher than the average of the eleven months ended November 30, 2009. Propane is the principal product sold. Propane sales are seasonal with most
sales occurring

in the winter heating season. In addition, the sales price of propane in December 2009 was approximately $1.20 per gallon which was the high for the year.

Costs of products sold

Costs of products sold in December 2009 was approximately 95 percent higher than the average of the eleven months ended November 30, 2009. As a result of fresh-start reporting, inventory was revalued
from historical weighted average cost to current market value on November 30, 2009. This revaluation increased the costs of products sold in December by approximately $9 million over what would have otherwise been the case.

Operating expense

Operating expense in December 2009 is approximately double the average of the eleven months ended November 30, 2009. The increase is due primarily to bad debt expense recorded in December.

General and administrative expense

General and administrative expense in December 2009 is approximately three times the average of the eleven months ended November 30, 2009. During bankruptcy, certain costs related to the
reorganization and governance of the Company were classified as reorganization items; however, after emergence such costs were classified as general and administrative expenses.

2011 versus 2010

Revenue

Revenue decreased in 2011 to $23 million from $38 million
in 2010. The decline in revenue is a result of a decline in the volume of storage leased. High crude oil prices and backwardated market conditions (i.e., prices for future deliveries are lower than current prices) and are forecast to continue into
2012. These factors have a negative effect on storage economics. As a result, the demand for storage is depressed and we have experienced difficulty securing contract renewals. We are uncertain when market conditions will improve.

Operating expense

Operating expense decreased in 2011 to $6 million from $8 million in 2010. This decline is due primarily to a reduction in employee related expenses such as the elimination of the short-term incentive
program.

Loss on disposal or impairment

During the fourth quarter of each year, we perform a goodwill impairment test for each of our segments that has goodwill. SemLogistics
passed the 2011 test initially, however, a review of the sensitivity of the test results indicated that a ten percent reduction in the estimated revenue in 2012 and 2013 would result in a test failure. The sensitivity of the test results to loss of
revenue, led us to conclude that impairment of the goodwill of SemLogistics was required. Accordingly, we impaired the full amount of goodwill which was $44.7 million on October 1, 2011.

General and administrative expense

General and administrative expense increased in 2011 to $7 million from $5 million in 2010. This increase is due to an increase in employee related expenses such as costs related to deferred capital
projects and severance costs.

2010 versus Eleven Months ended November 30, 2009

Revenue

Revenue increased in 2010 to $38 million from $33 million in the eleven months ended November 30, 2009. All available storage capacity was leased throughout 2010. This increase is due primarily to a
larger volume of products in storage in 2010 compared to 2009. In addition, storage fees and terminalling revenues were higher in 2010 compared to 2009.

General

In every category of expense, the amounts for the year 2010
are roughly equivalent to those of the eleven months ended November 30, 2009.

December 2009 versus average of Eleven
Months ended November 20, 2009

General

In each case, the December 2009 amount is roughly equivalent to the average of the eleven months ended November 30, 2009.

2011 versus 2010

Revenue

Revenue increased in 2011 to $163 million from $145 million in 2010. This increase results from increased costs passed through ($10 million), settlement of two disputes ($8 million), foreign exchange gain
($7 million) and higher capital fees ($3 million), offset, in part, by plant outages ($4 million) and gas volume withheld by two producers ($4 million).

Operating expense

Operating expense increased in 2011 to $111
million from $95 million in 2010. This increase results from higher power costs ($7 million), higher outside services and materials ($6 million), plant outage repairs ($6 million), foreign exchange loss ($4 million), turnaround planning and general
maintenance ($3 million) and severance costs ($2 million), offset in part by recovery of previously written off receivables ($4 million), reductions in accruals ($3 million), reduced salary expense due to staff reductions ($3 million) and
settlements of various disputes ($2 million).

General and administrative expense

General and administrative expense decreased in 2011 to $17 million from $19 million in 2010. This decrease results primarily from reduced
employee costs ($5 million) offset in part by severance costs ($2 million).

2010 versus Eleven Months ended
November 30, 2009

General

On July 22, 2008, the Company filed petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Also on July 22, 2008, the Companys Canadian subsidiaries filed applications
for creditor protection in Canada under the Companies Creditors Arrangement Act. As a result of the Bankruptcy petitions, the Company lost control of this subsidiary and it was deconsolidated on that date. The Company regained control of this
subsidiary upon emergence from the Bankruptcy on November 30, 2009, and consolidated this subsidiary again beginning on that date.

As a result of the deconsolidation between July 22, 2008, and the reconsolidation on November 30, 2009, it is not possible to make any meaningful comparisons of results of operations for 2010
and 2009.

December 2009

Loss on disposal or impairment

During December 2009, SemCAMS
committed to a plan to cease processing sour gas at one of its facilities based on a decision by a customer to send its sour gas to a different SemCAMS processing facility. As a result, SemCAMS recorded a reduction of $18.4 million to the value of
property, plant and equipment and a $4.7 million increase to the related asset retirement obligation.

2011 versus 2010

Revenue

Revenue increased in 2011 to $218 million from $150 million
in 2010. Higher volume (378 thousand tons versus 295 thousand tons) accounts for 61 percent of this increase and higher sales prices ($570/ton versus $500/ton) accounts for the remaining 39 percent of the increase. These increases reflect both
successful marketing efforts, in general, and a slight increase in sales volume of higher priced polymer modified asphalt and emulsions.

Costs of products sold

Costs of products sold increased in 2011 to
$192 million from $129 million in 2010. On a per ton basis, 2011 was $507 compared to $438 in 2010. The increase in cost per ton is essentially the same as the increase in revenue per ton described above.

2010 versus Eleven Months ended November 30, 2009

Revenue

Revenue decreased in 2010 to $150 million from $167 million
in the eleven months ended November 30, 2009. Lower volume reduced revenue by $38 million and was partially offset by higher prices, which increased revenue by $21 million. The decline in volume reflects weak demand as a result of a slowdown in
the issuance of government contracts for road construction projects in Mexico.

Costs of products sold

Costs of products sold decreased in 2010 to $129 million from $144 million in the eleven months ended
November 30, 2009. The decrease in the costs of products sold reflects a decline in volume offset, in part, by higher prices.

General and administrative

General and administrative expense
increased in 2010 to $10 million from $7 million in the eleven months ended November 30, 2009. This increase is due primarily to an allocation of corporate overhead. Prior to emergence from bankruptcy, no corporate overhead was allocated to
this business segment. Upon emergence, the decision was made to include SemMexico as a recipient of the allocation of corporate overhead.

##### Table of Contents

Depreciation and amortization

Depreciation and amortization increased in 2010 to $6 million from $3 million in the eleven months ended November 30, 2009. This
increase is primarily due to intangible asset values which were written up as a result of fresh-start reporting.

Loss
on disposal or impairment

During the 2010 annual test of goodwill for impairment, it was determined that goodwill for
this reporting segment was impaired by approximately $9 million. This impairment is due primarily to a slowdown in road construction projects in Mexico.

December 2009 versus average of Eleven Months ended November 30, 2009

Revenue

Revenue in December 2009 is approximately 20 percent lower than the average of the eleven months ended November 30, 2009. The primary reason for the decline in volume is that December is usually a
low volume month due to the holiday season. In addition, prices were down approximately 4 percent compared to the eleven month average primarily as a result of product mix.

Costs of products sold

Costs of products sold in December 2009 was
approximately 22 percent lower than the average of the eleven months ended November 30, 2009. This decline is primarily related to volume as explained above.

Operating expense

Operating expense in December 2009 is
approximately three times the average of the eleven months ended November 30, 2009. The increase is due primarily to bad debt expense recorded in December.

General and administrative expense

General and administrative
expense in December 2009 is approximately twice the average of the eleven months ended November 30, 2009. This increase is due primarily to an allocation of corporate overhead. Prior to emergence from bankruptcy, no corporate overhead was
allocated to this business segment. Upon emergence, the decision was made to include SemMexico as a recipient of the allocation of corporate overhead.

2011 versus 2010

Revenue

Revenue increased in 2011 to $105 million from $76 million in 2010. Higher volume (19,692 MMcf versus 15,697 MMcf) accounts for 65 percent of this increase and higher sales prices ($5.35/Mcf versus
$4.83/Mcf) account for the remaining 35 percent of the increase. The price per Mcf shown is the revenue derived from the sale of natural gas and natural gas liquids divided by total wellhead volume during the period.

Costs of products sold

Costs of products sold increased in 2011 to $75 million from $51 million in 2010. The increase is primarily related to higher volume and prices as described above. In addition, certain contracts were
revised to be more favorable to producers which resulted in higher costs of products sold expressed as a percentage of revenue.

Operating expense

Operating expense increased in 2011 to $9 million from $6 million in 2010. This increase is primarily a reflection of higher volume processed resulting in higher field expenses, labor costs, property
taxes, maintenance and outside services.

2010 versus Eleven Months ended November 30, 2009

Revenue

Revenue increased in 2010 to $76 million from $55 million in the eleven months ended November 30, 2009. This increase is due almost entirely to price as volume is flat between the periods.

##### Table of Contents

Costs of products sold

Costs of products sold increased in 2010 to $51 million from $38 million in the eleven months ended November 30, 2009. The increase
is due to higher prices of natural gas processed in 2010 compared to 2009. The change in volume between the periods is immaterial.

Operating expense

Operating expense decreased in 2010 to $6 million
from $9 million in the eleven months ended November 30, 2009. This decline reflects a reduction in compression costs, property taxes, various field costs such as electricity and lubricants and the collection of an account receivable which had
been fully reserved.

General and administrative expense

General and administrative expense increased in 2010 to $7 million from $4 million in the eleven months ended November 30, 2009. The
amount of corporate overhead allocated to this reporting segment increased because during bankruptcy certain costs related to the reorganization and governance of the Company were classified as reorganization items; however, after emergence such
costs were classified as general and administrative expense. In addition, incentive compensation expense contributed to the increase in general and administrative expense.

Depreciation and administrative expense

Depreciation and
amortization expense decreased in 2010 to $5 million from $8 million in the eleven months ended November 30, 2009. This reduction reflects higher asset valuations in 2009 prior to the write down of certain assets in November 2009.

December 2009 versus average of Eleven Months ended November 30, 2009

Revenue

Revenue in December 2009 is approximately 32 percent higher than the average of the eleven months ended November 30, 2009. This increase is a result of significantly higher sales prices in December
offset in part, by lower volumes of natural gas processed in December.

Costs of products sold

Costs of products sold in December 2009 was approximately 31 percent higher than the average of the eleven months ended November 30,
2009. This increase is a result of significantly higher purchase prices in December offset, in part, by lower volumes of natural gas processed in December.

General and administrative expense

General and administrative
expense in December 2009 is approximately two and a half times the average of the eleven months ended November 30, 2009. During bankruptcy, certain costs related to the reorganization and governance of the Company were classified as
reorganization items; however, after emergence such costs were classified as general and administrative expenses.

Liquidity and Capital Resources

Sources and Uses of Cash

Revolving Credit Facility

On June 20, 2011, we entered into a $325 million revolving credit facility, which can be utilized by our SemStream, SemCAMS and SemGas segments. On July 25, 2011, this credit facility was
increased to a total of $350 million. Later, on December 14, 2011, this credit facility was decreased to $320 million. This revolving credit facility expires in 2016. There was $82.0 million outstanding on the revolving credit facility at
December 31, 2011. The interest rate in effect was 5.13% on $7.0 million and 3.16% on $75.0 million. On January 13, 2012, the capacity on this facility was reduced to $300 million. In connection with the revolving credit facility, we paid
$5.1 million of financing fees that were capitalized and will be amortized over the life of the facility. This facility may, under certain conditions, be increased by up to an additional $100.0 million.

The revolving credit facility includes a $250.0 million sub-limit for the issuance of letters of credit for the account of SemGroup or
its loan parties in U.S. Dollars, and within this sublimit, $10.0 million may be utilized for the issuance of letters of credit for the account of our Canadian subsidiary, SemCAMS ULC. Letters of credit bear interest from 2.5% to 4.0%, based on a
leverage ratio, and are charged a fronting fee of 0.25%. At December 31, 2011, there was $12.5 million in letters of credit outstanding and the interest rate in effect was 2.88%.

At our option, amounts borrowed under the revolving credit facility will bear interest at either the Eurodollar rate or an alternate base
rate (ABR), plus, in each case, an applicable margin. The applicable margin will range from 2.50% to 4.00% in the case of a Eurodollar rate loan, and from 1.50% to 3.00% in the case of an ABR loan, based on a leverage ratio. We elect the
alternate base rate primarily for short-term borrowings. A three-day notice is required to initiate a Eurodollar-based borrowing.

We are required to pay a commitment fee of 0.50% on the unused portion of the revolving line of credit, which was $225.5 million at December 31, 2011. Additionally, we pay an administrative fee of
$0.1 million

annually. Alternative base rate interest and bank fees are paid quarterly; Eurodollar interest is paid at the end of each interest period. For the year ended December 31, 2011, interest
expense related to the revolving credit facility was $2.8 million, of which $1.1 million related to amortization of capitalized financing costs and write offs of capitalized financing costs due to reduction in overall revolver capacity.

All outstanding borrowings under the revolving credit facility will be due and payable on June 20, 2016. All letters of credit will
expire on June 13, 2016.

The agreement for the credit facilities (which encompass the revolving credit facility and the
term loans) contains various covenants that limit, among other things, the ability of SemGroup Corporation, as the borrower, with its restricted subsidiaries, to incur indebtedness, grant certain liens supporting indebtedness, merge or consolidate,
sell all or substantially all of its assets, enter into certain affiliate transactions, make certain distributions, and allow any material change in the nature of its business. Significant financial covenants under the credit facilities include:



| |  |  | Leverage Ratioratio of consolidated net debt to EBITDA (each as defined in the credit facilities, with EBITDA measured on a rolling
four-quarter basis) must be no greater than 4.5 to 1. The leverage ratio was 0.74 to 1.0 at December 31, 2011.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Interest Coverage Ratioratio of EBITDA to cash interest expense (each as defined in the credit facilities, measured on a rolling
four-quarter basis, with the first full year of cash interest expense measured on an annualized basis) must be no less than 2.5 to 1. The interest coverage ratio was 11.34 to 1.0 at December 31, 2011.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Each of the above ratios will be tested, beginning September 30, 2011, at the end of each fiscal quarter. As of December 31,
2011, we were in compliance with our covenants under the credit facilities.

The revolver loan includes customary events of
default, including events of default relating to non-payment of principal and other amounts owing under the credit facilities from time to time, including in respect of letter of credit disbursement obligations, inaccuracy of representations and
warranties in any material respect when made or when deemed made, violation of covenants, cross payment-defaults of SemGroup and its restricted subsidiaries to any material indebtedness, cross acceleration to any material indebtedness, bankruptcy
and insolvency events, the occurrence of a change of control, certain unsatisfied judgments, certain ERISA events, certain environmental matters and certain assertions of or actual invalidity of certain loan documents. A default under the credit
facilities would permit the participating banks to terminate commitments, require immediate repayment of any outstanding loans with interest and any unpaid accrued fees, and require the cash collateralization of outstanding letter of credit
obligations. In addition, the credit facilities prohibit any commodity transactions that are not permitted by our Comprehensive Risk Management Policy.

The credit facilities restrict our ability to make certain types of payments relating to our capital stock, including the declaration or payment of dividends. Dividends are limited to $10 million plus an
allowable amount as defined by the credit facilities. At December 31, 2011, dividends are limited to $10 million. The credit facilities are:



| |  |  | guaranteed by all of SemGroups material domestic subsidiaries; and
| | - |  | -------------------------------------------------------------------



| |  |  | secured by a lien on substantially all of the property and assets of SemGroup and the loan parties, subject to customary exceptions.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------

The credit facilities permit, with certain conditions, the sale or transfer of assets into Rose Rock, a
master limited partnership.

Term Loan A

On June 20, 2011, we entered into a five-year Term Loan A credit facility with a principal balance of $75.0 million. On September 30, 2011, we made a required quarterly principal payment of $0.9
million on this term loan. On November 1, 2011, we paid down $25.2 million in principal with the proceeds from a transaction with

NGL Energy. Proceeds received on December 14, 2011, from the Rose Rock IPO were used to pay down the remaining principal balance of $48.9 million plus accrued interest. No principal or
accrued interest remains outstanding under the Term Loan A credit facility and the Term Loan A credit facility has been terminated. For the year ended December 31, 2011, interest expense related to the Term Loan A facility was $2.7 million, of
which $1.5 million related to the amortization of capitalized financing costs and write offs of capitalized financing costs due to repayment of the Term Loan A facility.

Term Loan B

On June 20, 2011, we entered into a seven-year Term Loan
B credit facility with a principal balance of $200.0 million. This facility, along with the Term Loan A described above, replaced the previous term loan facility of $308.0 million, which was paid in full on June 20, 2011.

On September 30, 2011, we made a required principal payment of $0.5 million on this Term Loan B. On November 1, 2011, we paid
down $67.9 million in principal with the proceeds from a transaction with NGL Energy. Proceeds received on December 14, 2011 from the Rose Rock IPO were used to pay down the remaining principal balance of $131.6 million plus accrued interest.
No principal or accrued interest remains outstanding under the Term Loan B credit facility and the Term Loan B credit facility has been terminated. For the year ended December 31, 2011, interest expense related to the Term Loan B facility was
$10.4 million, of which $5.2 million related to the amortization of capitalized financing costs and write offs of capitalized financing costs due to repayment of the Term Loan B facility.

Rose Rock Revolving Credit Facility

On November 10, 2011, Rose Rock entered into a $150.0 million senior secured revolving credit agreement with The Royal Bank of Scotland, as administrative agent, and a syndicate of lenders. The
credit facility is available to fund working capital, for the issuance of up to $75 million of letters of credit, to finance capital expenditures and other permitted payments and for other lawful corporate purposes and will allow Rose Rock to
request that the maximum amount of the credit facility be increased by up to an additional $200 million, subject to receiving increased commitments from lenders or commitments from other financial institutions. At December 31, 2011, Rose Rock
had no outstanding borrowings on the revolving credit facility and had $22.6 million outstanding in letters of credit. Rose Rocks obligations under the credit facility are secured by a first priority lien on substantially all of its material
assets. The credit facility matures on December 14, 2016. Borrowings under the credit facility bear interest at either an alternate base rate or an adjusted Eurodollar rate, in each case plus an applicable margin. The applicable margin varies based
upon Rose Rocks Leverage Ratio, as defined in the credit facility. At December 31, 2011, had there been any borrowings under the revolving credit, the interest rate applicable would have been 4.50% and the interest rate applicable to
Eurodollar rate borrowings would have been the Eurodollar margin of 2.25% plus the applicable LIBOR rate.

Fees are charged on
any outstanding letters of credit at a rate that ranges from 2.25% to 3.25% depending on a leverage ratio specified in the credit agreement. In addition, a fronting fee of 0.25% is charged on outstanding letters of credit.

A commitment fee that ranges from 0.375% to 0.50%, depending on a leverage ratio specified in the credit agreement is charged on any
unused capacity of the revolving credit facility. In addition, Rose Rock is charged an annual administrative fee of $0.1 million. The credit facility also allows for the use of secured bilateral letters of credit. At December 31, 2011, we had $17.0
million of bilateral letters of credit outstanding and the interest in effect was 1.75%.

The credit facility contains
representations and warranties and affirmative and negative covenants customary for transactions of this nature. The negative covenants limit or restrict Rose Rocks ability (as well as the ability of its Restricted Subsidiaries, as defined in
the credit facility) to:



| |  |  | permit the ratio of its consolidated EBITDA to its consolidated cash interest expense at the end of any fiscal quarter, for the immediately preceding
four quarter period, to be less than 2.50 to 1.00;

As of December 31, 2011, Rose Rock was in compliance
with the covenants.

The credit agreement also contains events of default customary for transactions of this nature, including
the failure by SemGroup to directly or indirectly own a majority of the equity interests of the general partner of Rose Rock. Upon the occurrence and during the continuation of an event of default under the credit facility, the lenders may, among
other things, terminate their revolving loan commitments, accelerate and declare the outstanding loans to be immediately due and payable and exercise remedies against Rose Rock and the collateral as may be available to the lenders under the credit
facility and other loan documents.

SemLogistics Credit Facility

SemLogistics entered into a credit agreement in December 2010, which includes a £15 million term loan and a
£15 million revolving credit facility (U.S. $23 million each, at December 31, 2011 exchange rates). The facility is secured by the assets of SemLogistics Milford Haven Limited. The proceeds from this new facility were used to retire
SemLogistics previous credit facility.

At December 31, 2011, no cash borrowings were outstanding under the
revolving facility and no letters of credit were utilized.

##### Table of Contents

Interest is charged on both the term loan and the revolving loans (including letters of
credit) at a floating rate, which is calculated as the LIBOR plus a margin that ranges from 1.75% to 2.5%, depending on whether SemLogistics meets certain financial ratios specified in the agreement. The interest rate in effect at December 31,
2011 was 2.84%, which was calculated as 1.75% plus the LIBOR rate of 1.09%. Interest on the term loan and revolving facility are payable quarterly. A commitment fee of 0.50% is charged on any unused commitments under the facility and is payable
quarterly. SemLogistics also paid fees of $1.3 million upon inception of the facility, which were recorded to other noncurrent assets and are being amortized over the life of the facility.

During February 2011, we entered into three interest swap agreements totaling £7.5 million. We pay a fixed rate on the swaps of
2.49% and they expire on March 31, 2014. We entered into these swaps to offset a portion of the variable interest rate payments due on the term loan. We receive a floating rate equal to the three month LIBOR on the same notional amount. The
swaps notional amount declines to £7 million during the last year.

The facility is secured by the assets of
SemLogistics. The facility contains covenants, which, among other things, restrict the ability of SemLogistics to incur additional indebtedness, create liens on assets, make investments, restricted payments, loans or advances, dispose of assets, or
change the nature of its business. The facility contains covenants that require SemLogistics to maintain certain financial ratios specified in the agreement. At December 31, 2011, SemLogistics was in compliance with the covenants.

SemLogistics used the proceeds from the term loan to retire its previous credit agreement, which it had entered into on November 30,
2009. The previous facility bore interest at a floating rate which was calculated as LIBOR plus 5.5% (or 6.0%, if a specified financial target was not met). In addition, SemLogistics paid $2.1 million of fees to the lender at the inception of the
agreement.

SemLogistics recorded interest expense of $1.0 million for the year ended December 31, 2011, including
amortization of debt issuance costs. SemLogistics recorded interest expense of $4.0 million for year ended December 31, 2010, including amortization of debt issuance costs. SemLogistics recorded the fair value of the interest swaps as a
noncurrent liability of $0.4 million at December 31, 2011, with a corresponding adjustment to other comprehensive income (net of income taxes).

At December 31, 2011, the outstanding balance of the SemLogistics credit facility has been classified as a current liability as we have committed to the banks to terminate the credit facility by March 31,
2012. The interest rate swaps will be terminated with an expected loss on closure of £250,000 (U.S. $0.4 million at the December 31, 2011 exchange rate). At December 31, 2011, unamortized capitalized loan fees of $0.8 million were included in
other assets, net on the consolidated balance sheet.

SemMexico Revolving Credit Facilities

During 2010, SemMexico entered into a credit agreement that allowed SemMexico to borrow up to 80 million Mexican pesos at any time
through June 2011. Borrowings on this facility are required to be repaid with monthly payments through May 2013. At December 31, 2011, borrowings of $56.7 million pesos (U.S. $4.0 million) were outstanding on this facility. Borrowings are
unsecured and bear interest at the bank prime rate in Mexico plus 1.5%. At December 31, 2011, the interest rate in effect was 6.31%, calculated as 1.5% plus the bank prime rate of 4.81%.

At December 31, 2011, SemMexico also has outstanding letters of credit of 210 million Mexican pesos (U.S. $15.0 million at the
December 31, 2011 exchange rate). Fees are generally charged on outstanding letters of credit at a rate of 0.40% for 196 million Mexican pesos (U.S. $14.0 million) in letters of credit and 1% for 14 million Mexican pesos (U.S. $1.0
million) in letters of credit.

During 2011, SemMexico entered into an additional credit agreement that allows SemMexico to
borrow up to 56 million Mexican pesos (U.S. $4.0 million at the December 31, 2011 exchange rate) at any time during the term of the facility, which matures in August 2012. Borrowings would be unsecured and would bear interest at the bank
prime rate in Mexico plus 1.7%.

SemMexico recorded interest expense of $365,000 during the year ended December 31,
2011 related to these facilities.

SemCrude Pipeline, L.L.C. Term Loan Facility

On November 30, 2009, we entered into a $125 million SemCrude Pipeline, L.L.C. (SemCrude Pipeline) term loan facility
(the SCPL Term Loan Facility). The proceeds were used to refinance SemCrude Pipelines pre-petition term loan and pay the associated closing costs. The SCPL Term Loan Facility was secured by SemCrude Pipelines equity interest
in White Cliffs Pipeline, L.L.C. On September 29, 2010, approximately $107.3 million of the proceeds from the closing of the sale of ownership interests in the White Cliffs Pipeline, pursuant to the exercise of certain purchase options by two
shippers that had entered into throughput agreements with us, was used to pay down all principal outstanding and accrued interest under the SCPL Term Loan Facility. No principal or accrued interest remains outstanding under the SCPL Term Loan
Facility and the SCPL Term Loan Facility was retired on September 29, 2010.

LiquiditySources and Uses

Our primary sources of liquidity are cash flows generated from our operating activities and borrowing capacity under our
credit facilities. Our primary liquidity requirements are working capital, debt service, contractual obligations and capital expenditures. The consolidated cash balance on December 31, 2011 was approximately $116 million, although approximately
$40 million is considered restricted cash primarily for the settlement of pre-petition bankruptcy claims. Of the $116 million in consolidated cash, approximately $50 million was held in Canada and would be subject to tax if transferred to the United
States. We expect to have adequate liquidity to fund our liquidity requirements over the foreseeable future from cash flows generated from operating activities and available borrowing capacity under our credit facilities.

The following table summarizes our changes in cash for the periods presented:

Operating Activities

For the year ended December 2011, we had positive cash flows from operations of $74 million. Net income of $2.8 million included non-cash
expenses of $64.8 million. Of this amount, $51.2 million related to depreciation and amortization and an additional $30.3 million to the amortization and write down of debt issuance costs. These non-cash expenses were partially offset by $14.1
million in unrealized gains on derivative instruments. Changes in operating assets and liabilities increased cash flows by $6.4 million.

##### Table of Contents

For the year ended December 2010, we had positive cash flows from operations of $122.6
million. A net loss of $132.1 million included non-cash expenses of $192.2 million. The primary non-cash expense was $105.1 million of loss on disposal or impairment of long-lived assets. Of this amount, $91.8 related to the impairment of goodwill
and intangible assets in Canada and an additional $8.9 million related to the impairment of goodwill of our Mexican subsidiary. Changes in assets and liabilities increased operating cash flows by $62.4 million. The changes in assets and liabilities
include a decrease in restricted cash of $182.9 million. The decrease in restricted cash of $182.9 million primarily reflects payments to pre-petition creditors. This is offset by the $217.5 million decrease in payables to pre-petition creditors as
a result of payments to those creditors. The remaining elements in the changes in assets and liabilities net to positive cash flow of $97.0 million.

In the month of December 2009, we had negative cash flows from operations of $3.2 million. A net loss of $37.9 million was partially offset by non-cash expenses of $34.5 million. The most significant
non-cash expense was $23.1 million which related to the impairment of a Canadian gas plant. Changes in assets and liabilities further offset the loss by $0.2 million. The most significant elements in the changes in assets and liabilities include a
decrease in other current assets of $31.8 million, an increase in restricted cash of $36.9 million and a decrease in payables to pre-petition creditors of $26.8 million. The remaining elements in the changes in assets and liabilities net to positive
$32.1 million.

The decrease in other current assets of $31.8 million occurred as prepaid deposits were returned to the
Company by various vendors. The increase in restricted cash of $36.9 million (restricted for settlement of pre-petition claims) reflects collections of accounts receivable related to discontinued operations as well as recoveries of prepaid deposits.
The decrease in payables to pre-petition creditors is a result of payments to those creditors.

For the eleven months ended
November 2009, we had negative cash flows from operations of $549.5 million. Net income of $3,394.1 million was offset by non-cash adjustments of $4,173.4 million, $4,266.6 million of which related to plan of reorganization effects and fresh-start
reporting and other positive non-cash adjustments netting to $93.2 million. Changes in assets and liabilities reduced that offset by $230.0 million, including a decrease in accounts receivable of $318.7 million, a decrease in accounts payable and
accrued liabilities of $106.4 million and a decrease in inventory of $34.8 million. The remaining elements in the changes in assets and liabilities net to positive $17.7 million.

The decrease in accounts receivable of $318.7 million reflects the resolution of many disputes with customers who contested the
receivables as a result of the Bankruptcy. Ultimately these receivables were collected, settled or written off.

The decrease
of $106.4 million in accounts payable and accrued liabilities also reflects the resolution of certain disputes with customers. As part of the resolution of these disputes, certain of our accounts payable were netted against our receivables from
these customers.

The decrease in inventory of $34.8 million primarily reflects a $69 million decrease at SemMaterials (a
discontinued operation); a $10 million decrease at SemFuel (a discontinued operation); offset by a $41 million increase at SemStream.

Investing Activities

For the year ended December 2011, we had
positive cash flows of $36.9 million, primarily as a result of $93.1 million in proceeds from the sale certain SemStream assets to NGL Energy and $12.5 million in distributions from White Cliffs in excess of equity earnings. Cash inflows were
partially offset by $66.0 million in capital expenditures.

For the year ended December 2010, we had positive cash flows of
$121.2 million, primarily as a result of $140.8 million received from the sale of interests in White Cliffs. Cash outflows of $48.5 million in capital expenditures were partially offset by $24.5 million of proceeds received from the sale of assets.

##### Table of Contents

In the month of December 2009, we had net outflows of $8.0 million, primarily as a result of
$7.7 million in capital expenditures.

For the eleven months ended November 2009, we had net inflow of $5.0 million, primarily
as a result of $75.5 in proceeds from sales of assets of discontinued operations and the cash effect of reconsolidating our Canadian subsidiaries, offset in part by capital expenditures of $90.4 million. These capital expenditures relate primarily
to storage tanks at Cushing and the White Cliffs Pipeline.

Financing Activities

For the year ended December 2011, we had net outflows of $124.7 million, primarily as a result of $503.2 million of principal payments on
debt and $12.5 million in debt issuance costs, offset in part by $264.0 million in borrowings and $127.1 million in proceeds received from the sale of limited partner interests in Rose Rock.

For the year ended December 2010, we had net outflows of $191.8 million, primarily as a result of $348.7 million of principal payments on
debt offset in part by $159.2 million in borrowings.

In the month of December 2009, we had net outflows of $14 million as a
result of principal payments on debt.

For the eleven months ended November 2009, we had net inflows of $6.3 million,
primarily as a result of net borrowings of $12.7 million offset in part by $6.2 million in payment of debt issuance costs.

Off-Balance Sheet Arrangements

We do not use any off-balance sheet arrangements to enhance our liquidity and capital resources, or for any other purpose.

Capital Expenditures

The budget for capital expenditures in 2012 is
$180.0 million, including $150 million for strategic projects, $26 million for maintenance projects and $4 million for environmental and regulatory projects.

Commitments

Contractual Obligations

In the ordinary course of business we enter into various contractual obligations for varying terms and amounts. The following table

##### Table of Contents

In addition to the items in the table above, we have entered into various operational
commitments and agreements related to pipeline operations and to the marketing, transportation, terminalling and storage of petroleum products. We have also entered into certain petroleum products derivative instruments, which have a net fair value
of $0.2 million at December 31, 2011.

We had the right under our $300 million second lien term loan facility that we entered into
pursuant to our plan of reorganization to defer certain interest payments. We elected to defer the interest payment that was due on June 30, 2010 for interest incurred during the seven-month period then ended. Because of this deferral, interest
was charged at 11% during this period, instead of at 9%. We recorded an additional $3.5 million of interest expense in June 2010 to reflect the change in the interest rate upon making the decision to defer the interest payment. This term loan
facility was replaced in June 2011, and the replacement term loan facilities were paid in full in December 2011.

Letters of Credit

In connection with our purchasing activities, we provide certain suppliers and transporters with irrevocable standby letters of credit to secure our obligation for the purchase of petroleum products. Our
liabilities with respect to these purchase obligations are recorded as accounts payable on our balance sheet in the month the petroleum products are purchased. Generally, these letters of credit are issued for 70-day periods (with a maximum of
364-day periods) and are terminated upon completion of each transaction. At December 31, 2011 and December 31, 2010, we had outstanding letters of credit of approximately $52.1 million and $129.6 million, respectively.

Critical Accounting Policies and Estimates

Managements Discussion and Analysis of Financial Condition and Results of Operation are based upon our consolidated financial statements, which have been prepared in accordance with accounting
principles generally accepted in the U.S. The preparation of these financial statements and related disclosures requires the application of appropriate technical accounting rules and guidance, as well as the use of estimates and judgments that
affect the reported amount of assets, liabilities, revenue, expenses and related disclosures of contingent assets and liabilities. The application of these policies involves judgments regarding future events, including the likelihood of success of
particular projects and legal and regulatory challenges. These judgments, in and of themselves, could materially affect the financial statements and disclosures based on varying assumptions, which may be appropriate to use. In addition, the
financial and operating environment may also have a significant effect, not only on the operation of the business, but on the results reported through the application of accounting measures used in preparing the financial statements and related
disclosures, even if the nature of the accounting policies have not changed.

On an on-going basis, we evaluate these
estimates using historical experience, consultation with experts and other methods we consider reasonable. Actual results may differ substantially from our estimates. Any effects on our business, financial position or results of operations resulting
from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known.

Our significant accounting policies are summarized in Note 3 of our consolidated financial statements beginning on page F-1 of this Form
10-K. We identify our critical accounting policies as those that are the most pervasive and important to the portrayal of our financial position and results of operations, and that require the most difficult, subjective and complex judgments by
management regarding estimates about matters that are inherently uncertain.

Fresh-Start Reporting and Reorganization Value

As part of our emergence from the Bankruptcy on November 30, 2009, we implemented fresh-start reporting in accordance with ASC 852,
Reorganizations. Accordingly, our assets, liabilities and equity were adjusted to fair value. Our consolidated financial statements for periods subsequent to November 30, 2009, reflect a new basis of accounting and are not
comparable to our historical consolidated financial statements for periods prior to November 30, 2009.

Under fresh-start
reporting, a reorganization value is determined and allocated to our net assets based on their relative fair values in a manner similar to the accounting provisions applied to business combinations under ASC 805, Business
Combinations. Adjustments necessary to state our balance sheet accounts at fair value were made based on the work of management, financial consultants and independent appraisals. The estimates and assumptions used to derive the
reorganization value and the allocation of that value to assets is inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control. Modification to these assumptions could
have significantly changed the reorganization value and the resultant fair values of our assets.

Derivative Instruments

We follow the guidance of ASC 815, Derivatives and Hedging, to account for derivative instruments.
ASC 815 requires us to mark-to-market all derivative instruments on the balance sheet, and recognize changes in the fair value of non-hedge derivative instruments immediately in earnings. In certain cases, we may apply hedge accounting to our
derivative instruments. The criteria used to determine if hedge accounting treatment is



87



---

##### Table of Contents

appropriate are: (i) the designation of the hedge to an underlying exposure; (ii) whether the overall risk is being reduced; and (iii) if there is a correlation between the fair
value of the derivative instrument and the underlying hedged item. Changes in the fair value of derivative instruments accounted for as hedges are either recognized in earnings as an offset to the changes in the fair value of the related hedged
item, or deferred and recorded as a component of other comprehensive income and subsequently recognized in earnings when the hedged transactions occur.

Certain derivative instruments that meet the criteria for derivative accounting treatment also qualify for a scope exception to derivative accounting, as they are considered to be a normal purchase normal
sale (NPNS). The availability of this exception is based on the assumption that the Company has the ability, and it is probable, to deliver or take delivery of the underlying item. These assumptions are based on internal forecasts of
sales and historical physical delivery on contracts. Derivatives that are considered to be NPNS are exempt from derivative accounting treatment and are accounted for under accrual accounting. If it is determined that a transaction designated as NPNS
no longer meets the scope exception due to changes in estimates, the related contract would be recorded on the balance sheet at fair value combined with immediate recognition through earnings.

Income Taxes and Valuation Allowance for Deferred Tax Assets

As of December 31, 2011, we had a valuation allowance of $148.9 million on our deferred tax assets. Foreign tax credits of $77.3
million are the primary deferred tax asset. As of December 31, 2010, we had a valuation allowance of $162.2 million on our deferred tax assets. Foreign tax credits of $85.0 million are the primary deferred tax asset. In assessing the
recognition of our deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the existence of
sufficient taxable income of the appropriate character within the carryback and carryforward period available under the tax law. Sources of taxable income include future reversals of existing taxable temporary differences, future earnings and
available tax planning strategies.

Considerable judgment is required to determine the tax treatment of a particular item that
involves interpretations of complex tax laws. We are subject to examination by taxing authorities for income tax returns filed in the U.S. federal jurisdiction and various state and foreign jurisdictions including Canada, Mexico and the United
Kingdom.

Evaluation of Assets for Impairment for Other Than Temporary Decline in Value

In accordance with ASC 360, Property, Plant and Equipment, we evaluate property, plant and equipment and certain
intangible assets for impairment whenever indicators of impairment exist. Examples of such indicators are:



| |  |  | significant decrease in the market price of a long-lived asset;
| | - |  | ---------------------------------------------------------------



| |  |  | significant adverse change in the manner an asset is used or its physical condition;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | adverse business climate;
| | - |  | -------------------------



| |  |  | accumulation of costs significantly in excess of the amount originally expected for the construction or acquisition of an asset;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | current period loss combined with a history of losses or the projection of future losses; and
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | change in our intent about an asset from an intent to hold such asset through the end of its estimated useful life to a greater than fifty percent
likelihood that such asset will be disposed of before then.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Recoverability of assets to be held and used is
measured by comparison of the carrying amount of the assets to the future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the
carrying amount exceeds the fair value of the assets. Generally, fair value will be determined using valuation techniques such as the present value of expected future cash flows. However, actual future market prices and costs could vary from the
assumptions used in our estimates and the impact of such variations could be material.

Goodwill and Other Intangible Assets

We apply ASC 805, Business Combinations, and ASC 350, Intangibles  Goodwill and Other, to
account for goodwill and intangible assets. In accordance with these standards, we amortize all finite lived intangible assets over their respective estimated weighted average useful lives, while goodwill has an indefinite life and is not amortized.
However, goodwill and all intangible assets not subject to amortization are tested for impairment at least annually, or more frequently whenever an event or change in circumstances occurs that would more likely than not reduce the fair value of a
reporting unit below its carrying amount. We test for impairment at the reporting unit level using three valuation approaches: first, the income approach which measures the value of an asset by the present value of its future economic benefit;
second, the market approach which measures the value of an asset through the analysis of recent sales or offerings of comparable properties; and third, the cost approach which measures the value of an asset by the cost to reconstruct or replace it
with another of like utility. Estimation of future economic benefit requires management to make assumptions about numerous variables including selling prices, costs, the level of activity and appropriate discount rates. If it is determined that the
fair value of a reporting unit is below its carrying amount, our goodwill or intangible assets with indefinite lives will be impaired at that time.

Contingencies

We record a loss contingency when management
determines that it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such determinations are subject to interpretations of current facts and circumstances, forecasts of future events and estimates
of the financial impacts of such events. Gain contingencies are not recorded.



|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

This discussion on market risks represents an estimate of possible changes in future earnings that would occur assuming hypothetical
future movements in commodity prices, interest rates and currency exchange rates. Our views on market risk are not necessarily indicative of actual results that may occur, and do not represent the maximum possible gains and losses that may
occur since actual gains and losses will differ from those estimated based on actual fluctuations in interest rates or commodity prices and the timing of transactions.

We are exposed to various market risks, including volatility in (i) petroleum prices, (ii) interest rates and (iii) currency exchange rates. We may utilize from time-to-time various
derivative instruments to manage such exposure. Our risk management policies and procedures are designed to monitor physical and financial commodity positions and the resulting outright commodity price risk as well as basis risk resulting from
differences in commodity grades, purchase and sales locations and purchase and sale timing. We have a risk management function that has responsibility and authority for our Comprehensive Risk Management Policy, which governs our enterprise-wide
risks, including the market risks discussed in this item. Subject to our Comprehensive Risk Management Policy, our finance and treasury function has responsibility and authority for managing exposure to interest rates and currency exchange rates. To
manage the risks discussed above, we engage in price risk management activities. The following discussion addresses each category of risk. See Business Risk Governance and Comprehensive Risk Management Policy for more information
on our Comprehensive Risk Management Policy.

Commodity Price Risk

Commodity prices have historically been volatile and cyclical. For example, NYMEX WTI benchmark prices have ranged from an all-time high
of over $145 per barrel (June/July 2008) to a low of approximately $12 per barrel (March 1986) over the last 25 years.

Revenue from our asset-based activities is dependent on throughput volume, tariff rates, the level of
fees generated from our pipeline systems, capacity leased to third parties, capacity that we use for our own operational or marketing activities and the level of other fees generated at our terminalling and storage facilities. Profit from our
marketing activities is dependent on our ability to sell petroleum products at prices in excess of our aggregate cost. Margins may be affected during transitional periods between a backwardated market (when the prices for future deliveries are lower
than the current prices) and a contango market (when the prices for future deliveries are higher than the current prices). Our petroleum product marketing activities within each of our segments are generally not directly affected by the absolute
level of petroleum product prices, but are affected by overall levels of supply and demand for petroleum products and relative fluctuations in marked-related indices.

Based on our open derivative contracts at December 31, 2011, a 5% increase in the applicable market price or prices for each derivative contract would result in a less than $0.5 million decrease in
our crude oil sales revenues. A 5% decrease in the applicable market price or prices for each derivative contract would result in a less than $0.5 million increase in our crude oil sales revenues. However, the increases or decreases in crude oil
sales revenues we recognize from our open derivative contracts are substantially offset by higher or lower crude oil sales revenues when the physical sale of the product occurs. These contracts may be for the purchase or sale of crude oil or in
markets different from the physical markets in which we are attempting to hedge our exposure, or may have timing differences relative to the physical markets. As a result of these factors, our hedges may not eliminate all price risks.

Margin deposits or other credit support, including letters of credit, are generally required on derivative instruments utilized to manage
our price exposure. As commodity prices increase or decrease, the fair value of our derivative instruments changes, thereby increasing or decreasing our margin deposit or other credit support requirements. Although a component of our
risk-management strategy is intended to manage the margin and other credit support requirements on our derivative instruments, volatile spot and forward commodity prices, or an expectation of increased commodity price volatility, could increase the
cash needed to manage our commodity price exposure and thereby increase our liquidity requirements. This may limit amounts available to us through borrowing, decrease the volume of petroleum products we purchase and sell or limit our
commodity price management activities.

Interest Rate Risk

We utilize both fixed and variable rate debt and are exposed to market risk due to the floating interest rates on our credit
facilities. Therefore, from time-to-time we may utilize interest rate derivatives to manage interest obligations on specific debt issuances. Our variable rate debt bears interest at LIBOR or prime, subject to certain floors, plus the
applicable margin. At December 31, 2011, an increase in these base rates of 1%, above the base rate floors, would increase our interest expense by $1.1 million per year.

The average interest rates presented below are based upon rates in effect at December 31, 2011 and December 31, 2010. The
carrying value of the variable rate instruments in our credit facilities approximate fair value primarily because our rates fluctuate with prevailing market rates.

The following table summarizes our debt obligations:

Currency Exchange Risk

The cash flows relating to our U.K., Canada and Mexico operations are based on the U.S. dollar equivalent of such amounts measured in
British pounds, Canadian dollars and Mexican pesos. Assets and liabilities of our U.K., Canadian and Mexican subsidiaries are translated to U.S. dollars using the applicable exchange rate as of the end of a reporting period. Revenue, expenses and
cash flows are translated using the average exchange rate during the reporting period.

evaluated the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Based on our evaluation under that framework and applicable SEC rules, our management
concluded that our internal control over financial reporting was effective as of December 31, 2011.

Our internal control
over financial reporting as of December 31, 2011, has been audited by BDO USA, LLP, an independent registered public accounting firm, as stated in their report that is included herein.

Changes in Internal Control over Financial Reporting

There were no
changes in our internal control over financial reporting that occurred during the fiscal quarter ended December 31, 2011, that have materially affected, or that are reasonably likely to materially affect, our internal control over financial
reporting.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

SemGroup Corporation

Tulsa, Oklahoma

We have audited the accompanying consolidated balance sheets of SemGroup Corporation (formerly SemGroup, L.P.) (the Company) as of December 31, 2011, and 2010 (Successor) and the related
consolidated statements of operations and comprehensive income (loss), owners equity (deficit), and cash flows for the years ended December 31, 2011 and 2010 and for the one month ended December 31, 2009 (Successor), and for the
eleven months ended November 30, 2009 (Predecessor). These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of
SemGroup Corporation (formerly SemGroup, L.P.) at December 31, 2011 and 2010 (Successor), and the results of its operations and its cash flows for the years ended December 31, 2011 and 2010 and for the one month ended December 31,
2009 (Successor) and for the eleven months ended November 30, 2009 (Predecessor), in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 1 to the consolidated financial statements, effective November 30, 2009, the Company emerged from bankruptcy and applied fresh-start accounting. As a result, the statements of
consolidated operations and cash flows for the years ended December 31, 2011 and 2010 and for the one month ended December 31, 2009, are presented on a different basis than for the periods before fresh-start and, therefore, are not
comparable.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), SemGroup
Corporations internal control over financial reporting as of December 31, 2011, based on criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO) and our report dated February 29, 2012, expressed an unqualified opinion thereon.

have audited SemGroup Corporations internal control over financial reporting as of December 31, 2011, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations
of the Treadway Commission (the COSO criteria). SemGroup Corporations management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial
reporting, included in the accompanying Item 9A, Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the companys internal control over financial reporting based on our
audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other
procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A
companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect
the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of
unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, SemGroup Corporation maintained, in all material respects, effective internal control over financial reporting as of December 31,
2011, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), the consolidated balance sheets of SemGroup Corporation (formerly SemGroup, L.P.) as of December 31, 2011 and 2010 (Successor), and the related consolidated statements of operations and comprehensive income (loss),
owners equity (deficit), and cash flows for the years ended December 31, 2011 and 2010 and for the one month ended December 31, 2009 (Successor) and for the eleven months ended November 30, 2009 (Predecessor) and our report
dated February 29, 2012 expressed an unqualified opinion thereon.

SEMGROUP CORPORATION

Notes to Consolidated Financial Statements





|1. | OVERVIEW
|-- | --------

SemGroup Corporation is a Delaware corporation headquartered in Tulsa, Oklahoma that provides diversified services for
end-users and consumers of crude oil, natural gas, natural gas liquids, refined products and asphalt. SemGroup Corporation began operations on November 30, 2009, as the successor entity of SemGroup, L.P., which was an Oklahoma limited
partnership.

On July 22, 2008 (the Petition Date), SemGroup, L.P. and certain subsidiaries filed petitions
for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Also on July 22, 2008, SemGroup, L.P.s Canadian subsidiaries filed applications for creditor protection in Canada under the Companies Creditors Arrangement Act (the
CCAA). Later during 2008, certain other U.S. subsidiaries filed petitions for reorganization. While in bankruptcy, SemGroup, L.P. filed a Plan of Reorganization with the court, which was confirmed on October 28, 2009. The Plan of
Reorganization determined, among other things, how pre-Petition Date obligations would be settled, the equity structure of the reorganized company upon emergence, and the financing arrangements upon emergence. SemGroup Corporation emerged from
bankruptcy on November 30, 2009 (the Emergence Date).

The accompanying consolidated financial statements
include the activities of SemGroup Corporation (the Successor) from November 30, 2009 through December 31, 2011, and the activities of SemGroup, L.P. (the Predecessor) from January 1, 2009 through
November 30, 2009. The terms we, our, us, the Company and similar language used in these notes to consolidated financial statements refer to SemGroup Corporation, SemGroup, L.P. and their
subsidiaries. As described in Note 3, we applied fresh-start reporting on the Emergence Date. As a result, the financial statements of the Successor are not comparable to the financial statements of the Predecessor.

Our reportable segments include the following:



| |  |  | We previously referred to our crude business as SemCrude, but following the contribution of SemCrude, L.P. to Rose Rock, we have decided to refer to
this reportable business as Crude. Crude conducts crude oil transportation, storage, terminalling, gathering, blending, and marketing operations in the United States. Crudes assets include
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a 2% general partner interest and a 57.0% limited partner interest in Rose Rock Midstream, L.P. (Rose Rock), which owns an approximate
640-mile crude oil pipeline network in Kansas and Oklahoma, a crude oil gathering, storage and marketing business in the Bakken Shale in North Dakota and Montana and a crude oil storage facility in Cushing, Oklahoma with a capacity of
5.0 million barrels; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a 51% ownership interest in White Cliffs Pipeline, L.L.C., (White Cliffs) which owns a 527-mile pipeline that transports crude oil from
Platteville, Colorado to Cushing, Oklahoma (White Cliffs Pipeline).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | SemStream, which owns 8,932,031 common units representing 32.2% of the total limited partner interests, as of December 31, 2011, in NGL Energy
Partners LP (NGL Energy), which markets, transports and stores natural gas liquids in the United States, and a 7.5% interest in the general partner of NGL Energy. SemStream also owns and operates a residential propane supply business in
Page and Payson, Arizona.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | SemCAMS, which provides natural gas gathering and processing services in Alberta, Canada. SemCAMS owns working interests in, and operates, four natural
gas processing plants and a network of 600 miles of natural gas gathering and transportation pipelines.

aggregated and blended crude oil in Western Canada. Due to adverse market conditions impacting this segment, we sold the property, plant and equipment of SemCanada Crude in late 2010 and began winding down its operations (Note 6).

We disposed of numerous assets while in bankruptcy, including (Notes 6 and 7):



| |  |  | SemFuel, a refined products marketing and storage business in the United States;
| | - |  | --------------------------------------------------------------------------------



| |  |  | SemMaterials, an asphalt processing, storage, and marketing business in the United States;

Our SemCAMS segment owns undivided interests in certain natural gas gathering and processing assets, for which we record only our proportionate share of the assets on the consolidated balance sheets. The
net book value of the property, plant and equipment recorded by us associated with these undivided interests is approximately $167.4 million at December 31, 2011. We serve as operator of these facilities and incur the costs of operating the
facilities (recorded as operating expenses in the consolidated statements of operations) and charge the other owners for their proportionate share of the costs (recorded as other revenue in the consolidated statements of operations).

Equity method investments

At the end of September 2010, we sold a portion of our ownership interests in White Cliffs to two unaffiliated parties, which reduced our ownership interest in White Cliffs from approximately 99% to 51%.

|-- | -------------------------------------------------



Upon closing of this sale, the other owners received substantive rights to participate in the management of White Cliffs. Because of this, we deconsolidated White Cliffs at the end of September
2010, and began accounting for it under the equity method.

On November 1, 2011, we contributed the long-lived assets and
certain working capital of our SemStream segment to NGL Energy in return for limited partner interests in NGL Energy, an interest in the general partner of NGL Energy, and cash for working capital. We hold two seats on the board of directors of the
general partner of NGL Energy, and we account for our investment in NGL Energy and its general partner under the equity method.

Cost method investments

We lost control of several of our subsidiaries as a direct or indirect result of the bankruptcy petitions, including all Canadian subsidiaries, SemGroup Holdings, L.P. (which held our ownership interests
in SemGroup Energy Partners), and Wyckoff Gas Storage Company, L.L.C. These subsidiaries were de-consolidated during 2008 and subsequently accounted for as cost method investments. We regained control of SemCAMS and SemCanada Crude on the Emergence
Date, and consolidated these subsidiaries again beginning on that date.

Discontinued operations

As part of the process of reorganizing to emerge from bankruptcy, we disposed of certain of our operations. As described in Note 7,
SemFuel, SemMaterials, and SemEuro Supply met the criteria to be classified as discontinued operations in the consolidated financial statements.



|3. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|-- | ------------------------------------------

USE OF ESTIMATESThe preparation of financial statements in conformity with accounting principles generally
accepted in the United States requires management to make estimates and assumptions that affect the amounts and disclosures in the financial statements. Our significant estimates include, but are not limited to: (1) allowances for doubtful
accounts receivable; (2) estimated useful lives of assets, which impact depreciation; (3) estimated fair values of long-lived assets recorded in fresh-start reporting; (4) estimated fair values of long-lived assets used in impairment
tests; (5) fair values of derivative instruments; and (6) accrual and disclosure of contingent losses. Although management believes these estimates are reasonable, actual results could differ materially from these estimates.

FRESH-START REPORTINGWe adopted fresh-start reporting on the Emergence Date. In connection with fresh-start reporting, we
recorded the following at the Emergence Date:



| |  |  | assets, at their estimated fair values;
| | - |  | ---------------------------------------



| |  |  | goodwill, to the extent our reorganization value (described in Note 8) exceeded the amounts attributed to specific tangible or identified intangible
assets;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | liabilities, at their fair values; and
| | - |  | --------------------------------------



| |  |  | deferred tax liabilities, based on the adjusted balances of the assets to which they relate.
| | - |  | --------------------------------------------------------------------------------------------

CASH AND CASH EQUIVALENTSCash includes currency on hand and demand and time deposits with banks or other financial
institutions. Cash equivalents include highly liquid investments with maturities of three months or less at the date of purchase. Balances at financial institutions may exceed federally insured limits.

|-- | ----------------------------------------------------



RESTRICTED CASHAs described in Note 8, our Plan of Reorganization specified
the total amount of consideration we would provide to all pre-petition creditors in settlement of their claims. At December 31, 2011, we had not yet completed the process of disbursing funds to settle pre-petition claims, as we had not yet
completed the process of resolving all of the claims. The restricted cash balance at December 31, 2011 includes $37.5 million of cash that is restricted for this purpose. The December 31, 2011 restricted cash balance also includes $2.0
million of cash that is restricted for other purposes.

ACCOUNTS RECEIVABLEAccounts receivable are reported net of
the allowance for doubtful accounts. Our assessment of the allowance for doubtful accounts is based on several factors, including the overall creditworthiness of our customers, existing economic conditions, and the amount and age of past due
accounts. We enter into netting arrangements with certain counterparties to help mitigate credit risk. Receivables subject to netting are presented as gross receivables (with the related accounts payable also presented gross) until such time as the
balances are settled. Receivables are considered past due if full payment is not received by the contractual due date. Past due accounts are written off against the allowance for doubtful accounts only after all collection attempts have been
exhausted.

At the Emergence Date, as part of fresh-start reporting, we recorded accounts receivable at fair value. This was
accomplished by reducing the allowance for doubtful accounts to $-0- and recording a corresponding reduction to accounts receivable. We report any amounts we have collected in excess of the estimated Emergence Date fair value as reductions to
operating expenses in the consolidated statements of operations.

INVENTORIESInventories primarily consist of
natural gas and natural gas liquids, crude oil, and asphalt. Inventories are valued at the lower of cost or market, with cost generally determined using the weighted-average method. The cost of inventory includes applicable transportation costs.

We enter into exchanges with third parties whereby we acquire products that differ in location, grade, or delivery date from
products we have available for sale. These exchanges are valued at cost, and although a transportation, location or product differential may be recorded, generally no gain or loss is recognized.

PROPERTY, PLANT AND EQUIPMENTProperty, plant and equipment is recorded at cost (although, as described above, property, plant
and equipment was adjusted to fair value at November 30, 2009 upon adoption of fresh-start reporting). We capitalize costs that extend or increase the future economic benefits of property, plant and equipment, and expense maintenance costs that
do not. When assets are disposed of, their cost and related accumulated depreciation are removed from the balance sheet, and any resulting gain or loss is recorded as a gain or loss on disposal or impairment of long-lived assets in the consolidated
statements of operations.

Depreciation is calculated primarily on the straight-line method over the following estimated useful
lives:



|                                                |  |  |               | 
|----------------------------------------------- |  |  | ------------- | 
|Pipelines and related facilities                |  |  | 10  31 years | 
|Storage and terminal facilities                 |  |  | 10  25 years | 
|Natural gas gathering and processing facilities |  |  | 10  31 years | 
|Office and other property and equipment         |  |  | 3  31 years  | 

LINEFILLPipelines and storage facilities generally require a minimum volume of product in the
system to enable the system to operate. Such product, known as linefill, is generally not available to be withdrawn from the system. Linefill owned by us in facilities operated by us is recorded at historical cost, is included in property, plant and
equipment in the consolidated balance sheets, and is not depreciated. We also own linefill in third party facilities, which is included in inventory or in other noncurrent assets on the consolidated balance sheets.

|-- | ----------------------------------------------------



IMPAIRMENT OF LONG-LIVED ASSETSWe test long-lived asset groups for
impairment when events or circumstances indicate that the net book value of the asset group may not be recoverable. We test an asset group for impairment by estimating the undiscounted cash flows expected to result from its use and eventual
disposition. If the estimated undiscounted cash flows are lower than the net book value of the asset group, we then estimate the fair value of the asset group and record a reduction to the net book value of the assets and a corresponding impairment
loss.

GOODWILLWe test goodwill for impairment on an annual basis, or more often if circumstances warrant, by
estimating the fair value of the asset group to which the goodwill relates and comparing this fair value to the net book value of the asset group. If fair value is less than net book value, we estimate the implied fair value of goodwill, reduce the
book value of the goodwill to the implied fair value, and record a corresponding impairment loss. Prior to the Emergence Date, SemGroup L.P.s policy was to test goodwill for impairment on December 31 of each year. Subsequent to the
Emergence Date, SemGroup Corporations policy is to test goodwill for impairment on October 1 of each year. See Note 6 for discussion of goodwill impairment.

During September 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-08, Testing Goodwill for Impairment. This
ASU is designed to simplify how entities test goodwill for impairment. Under the new standard, an entity may first assess qualitative factors to determine whether it is more likely than not that the fair value of an asset group is less than the
carrying amount, for the purpose of determining whether it is necessary to estimate the fair value of the asset group to which the goodwill relates. We plan to adopt this new standard in 2012.

EQUITY METHOD INVESTMENTSWe account for an investment under the equity method when we have significant influence over, but
not control of, the significant operating decisions of the investee. Under the equity method, we record in the consolidated statements of operations our share of the earnings or losses of the investee, with a corresponding adjustment to the
investment balance on our consolidated balance sheet. When we receive a distribution from an equity method investee, we record a corresponding reduction to the investment balance.

For equity method investments for which we do not expect earnings information to be consistently available to record earnings in the
quarter in which they are generated, our policy is to record equity earnings on a one-quarter lag. This does not have a material impact on our financial statements.

DEBT ISSUANCE COSTSCosts incurred in connection with the issuance of long-term debt are reported as other noncurrent assets and are amortized to interest expense using the straight-line
method over the term of the related debt. Use of the straight-line method of amortization does not differ materially from the effective interest method.

COMMODITY DERIVATIVE INSTRUMENTSWe generally record the fair value of commodity derivative instruments on the consolidated balance sheets and the change in fair value as an increase or
decrease to product revenue.

As shown in Note 15, the fair value of commodity derivatives at December 31, 2011 and 2010
are recorded to other current assets or other current liabilities on the consolidated balance sheets. Related margin deposits are recorded to other current assets or other current liabilities on the consolidated balance sheets. Margin deposits are
not generally netted against derivative assets or liabilities.

The fair value of a derivative contract is determined based on
the nature of the transaction and the market in which the transaction was executed. Quoted market prices, when available, are used to value derivative transactions. In situations where quoted market prices are not readily available, we estimate the
fair value

using other valuation techniques that reflect the best information available under the circumstances. Fair value measurements of derivative assets include consideration of counterparty credit
risk. Fair value measurements of derivative liabilities include consideration of our creditworthiness.

We have elected
normal purchase and normal sale treatment for certain commitments to purchase or sell petroleum products at future dates. This election is only available when a transaction that would ordinarily meet the definition of a
derivative but instead is expected to result in physical delivery of product over a reasonable period in the normal course of business and is not expected to be net settled. Agreements accounted for under this election are not recorded at fair
value; instead, the transaction is recorded when the product is delivered.

PAYABLES TO PRE-PETITION CREDITORSAs
described in Note 8, our Plan of Reorganization specified the total amount of consideration we would provide to all pre-petition creditors in settlement of their claims. At December 31, 2011, we had not yet completed the process of disbursing
funds to settle pre-petition claims, as we had not yet completed the process of resolving all of the claims. We recorded a liability of $38.7 million at December 31, 2011 associated with these obligations, $0.9 million of which is associated
with discontinued operations and is reported within other current liabilities. Of this amount, $37.5 million is held in cash accounts which are restricted for this purpose. The remaining amount is associated with certain accounts receivable and
other current assets. Any proceeds received from these assets will be remitted to pre-petition creditors.

CONTINGENT
LOSSESWe record a liability for a contingent loss when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. We record attorneys fees incurred in connection with a contingent loss at the
time the fees are incurred. We do not record liabilities for attorneys fees that are expected to be incurred in the future.

ASSET RETIREMENT OBLIGATIONSAsset retirement obligations include legal or contractual obligations associated with the retirement of long-lived assets, such as requirements to incur costs to
dispose of equipment or to remediate the environmental impacts of the normal operation of the assets. We record liabilities for asset retirement obligations when a known obligation exists under current law or contract and when a reasonable estimate
of the value of the liability can be made.

DISCONTINUED OPERATIONSSemMaterials, SemFuel, and SemEuro Supply are
presented as discontinued operations in the consolidated financial statements. We classify a component of our business as a discontinued operation when we commit to a plan to sell the component and believe it is probable that a sale will be
completed within one year. A component that is disposed of in a manner other than by sale is classified as discontinued when the component is actually disposed. Investments accounted for under the equity method, or the cost method, do not qualify
for treatment as discontinued operations. A component that is disposed of may not qualify for treatment as a discontinued operation if we have significant continuing involvement in the operations of the component after the disposal.

Once a component meets the requirements to be classified as a discontinued operation, previous financial statements are retrospectively
adjusted to reflect the component as a discontinued operation for all periods presented. Income and losses of discontinued operations (excluding corporate general and administrative expense allocations) are combined into one line on the consolidated
statements of operations. The cash flows from discontinued operations are not separately identified in the consolidated statements of cash flows.

REVENUE RECOGNITIONSales of product, as well as gathering and marketing revenues, are recognized at the time title to the product transfers to the purchaser, which typically occurs upon
receipt of the product by the purchaser. Terminal and storage revenues are recognized at the time the service is



F-12

performed. Revenue for the transportation of product is recognized upon delivery of the product to its destination. Certain revenue transactions are reported on a net basis, including derivative
instruments considered held for trading purposes and certain buy/sell transactions (see Purchases and Sales of Inventory with the Same Counterparty). Taxes collected from customers and remitted to governmental authorities are recorded on
a net basis (excluded from revenue).

COSTS OF PRODUCTS SOLDCosts of products sold consists of the cost to
purchase the product, the cost to transport the product to the point of sale, and the cost to store the product until it is sold.

PURCHASES AND SALES OF INVENTORY WITH THE SAME COUNTERPARTYWe routinely enter into transactions to purchase inventory from, and sell inventory to, the same counterparty. Such transactions
that are entered into in contemplation of one another are recorded on a net basis.

INTEREST EXPENSE DURING
REORGANIZATIONWhile we were in bankruptcy, we only recorded interest expense to the extent such interest was expected to be paid. Interest obligations that were expected to be compromised in the reorganization process (i.e., not paid in
full) were not recorded as expenses. The total amount of interest that we would have been contractually obligated to pay, but which was compromised in the reorganization process and not recorded as an expense, was $221.0 million for the eleven
months ended November 30, 2009.

CURRENCY TRANSLATIONThe consolidated financial statements are presented in
U.S. dollars. Our segments operate in four countries, and each segment has identified a functional currency, which is the primary currency in the environment in which the segment operates. The functional currencies include the U.S.
dollar, the Canadian dollar, the British pound sterling, and the Mexican peso.

At the end of each reporting period, the assets
and liabilities of each segment are translated from its functional currency to U.S. dollars using the exchange rate at the end of the month. The monthly results of operations of each segment are generally translated from its functional currency to
U.S. dollars using the average exchange rate during the month. Changes in exchange rates result in currency translation gains and losses, which are recorded within other comprehensive income (loss).

Certain segments also enter into transactions in currencies other than their functional currencies. At the end of each reporting period,
each segment re-measures the related receivables, payables, and cash to its functional currency using the exchange rate at the end of the period. Changes in exchange rates between the time the transactions were entered into and the end of the
reporting period result in currency transaction gains or losses, which are recorded in the consolidated statements of operations.

INCOME TAXESDeferred income taxes are accounted for under the liability method, which takes into account the differences between the basis of the assets and liabilities for financial
reporting purposes and amounts recognized for income tax purposes. We record valuation allowances on deferred tax assets when, in the opinion of management, it is more likely than not that the asset will not be recovered.

We monitor uncertain tax positions and we recognize tax benefits only when management believes the relevant tax positions would more
likely than not be sustained upon examination. We record any interest and any penalties related to income taxes within income tax expense in the consolidated statements of operations.

REORGANIZATION ITEMSAs described in Note 1, we operated as a debtor-in-possession subject to the jurisdiction of the
bankruptcy court during the eleven months ended November 30, 2009. Revenues, expenses, realized gains and losses, and provisions for losses resulting from the reorganization and restructuring of the business during that period are reported as
reorganization items in the consolidated statement of operations. The effects of the adjustments to the reported amounts of assets and liabilities

resulting from the adoption of fresh-start reporting and the effects of the forgiveness of debt in the reorganization are reported within reorganization items in the consolidated statement of
operations for the eleven months ended November 30, 2009.

RECLASSIFICATIONSCertain reclassifications have
been made to conform prior year balances to the current year presentation.

EQUITY-BASED COMPENSATIONWe grant
certain of our employees equity-based compensation awards which vest contingent on continued service of the recipient or on their achievement of specific performance targets. We record compensation expense for these outstanding awards over
applicable service or performance periods based on their grant date fair value with a corresponding increase to additional paid-in capital.

COMPREHENSIVE INCOME (LOSS) AND ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)Comprehensive income (loss) is defined as a change in equity of a business enterprise during a period from
transactions and other events and circumstances from non-owner sources and includes all changes in equity during a period except those resulting from investments by owners and distributions to owners. Our comprehensive income (loss) consists of
currency translation adjustments, changes in the funded status of pension benefit plans and changes in the fair value of interest rate swaps.

During June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income. This ASU is designed to improve the comparability, consistency and transparency of financial
reporting and to increase the prominence of items reported in other comprehensive income. The amendments require that all non-owner changes in stockholders equity be presented either in a single continuous statement of comprehensive income or
in two separate but consecutive statements. This standard is complied with in these consolidated financial statements.

In
December 2011, the FASB issued ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05,
which deferred certain presentation requirements in ASU 2011-05 for items reclassified out of accumulated other comprehensive income. We plan to adopt this standard in 2012.



|4. | ROSE ROCK MIDSTREAM, L.P.
|-- | -------------------------

On December 14, 2011, our subsidiary Rose Rock Midstream, L.P. completed an initial public offering in which it sold 7,000,000 common
units representing limited partner interests. We received proceeds of $127.1 million from this offering, net of underwriter discounts and other fees associated with the offering. We used these proceeds to make principal payments on long-term debt.

Subsequent to the initial public offering, we own 59% of the partnership consisting of 57% limited partner interests that
include 1,389,709 common units and 8,389,709 subordinated units and the entire 2% general partner interest (342,437 units) of Rose Rock. We also own certain incentive distribution rights, which are described below. We control the operations of Rose
Rock through our ownership of the general partner interest, and we continue to consolidate Rose Rock. The outside ownership interests in Rose Rock are reflected in non-controlling interests in consolidated subsidiaries on our
consolidated balance sheet at December 31, 2011. The portion of the net income of Rose Rock subsequent to the initial public offering that is attributable to outside owners is reflected within net income attributable to non-controlling
interests in our consolidated statement of operations for the year ended December 31, 2011.

Rose Rock intends to pay a minimum quarterly distribution of $0.3625 per unit to the
extent it has sufficient available cash, as defined in Rose Rocks partnership agreement. Rose Rocks partnership agreement requires Rose Rock to distribute all of its available cash each quarter in the following manner:



| |  |  | first, 98.0% to the holders of common units and 2.0% to the general partner, until each common unit has received the minimum quarterly distribution of
$0.3625, plus any arrearages from prior quarters;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | second, 98.0% to the holders of subordinated units and 2.0% to the general partner, until each subordinated unit has received the minimum quarterly
distribution of $0.3625; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | third, 98.0% to all unitholders, pro rata, and 2.0% to the general partner, until each unit has received a distribution of $0.416875. If cash
distributions to the unitholders exceed $0.416875 per unit in any quarter, the general partner will receive, in addition to distributions on its 2.0% general partner interest, increasing percentages, up to 48.0%, of the cash Rose Rock distributes in
excess of that amount.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

On January 23, 2012, Rose Rock declared a distribution of $0.0670 per unit. This
distribution is the first declared by Rose Rock and the prorated amount corresponds to its minimum quarterly cash distribution of $0.3625 per unit, or $1.45 per unit on an annualized basis. The proration period began immediately after the closing of
Rose Rock Midstreams initial public offering, December 14, 2011, and continued through December 31, 2011. The distribution was paid on February 13, 2012 to all unitholders of record on February 3, 2012. Of this
distribution, $0.7 million was paid to us and $0.5 million was paid to outside owners.

White Cliffs

Until the end of September 2010, we owned 99.17% of White Cliffs, and the remaining interests were held by two unaffiliated parties. During 2010, both of these parties exercised their rights under an
agreement to purchase additional ownership interests in White Cliffs. Subsequent to the closing of these transactions, we own 51% of White Cliffs. After purchasing these ownership interests, the other owners have substantive rights to participate in
the management of White Cliffs; because of this, we deconsolidated White Cliffs at the end of September 2010, and began accounting for it under the equity method.

Under the equity method, we do not report the individual assets and liabilities of White Cliffs on our
consolidated balance sheets. Instead, our ownership interest is reflected in one line as a noncurrent asset on our consolidated balance sheets.

Certain summarized income statement information of White Cliffs for the year ended December 31, 2011 and the three months ended December 31, 2010 is shown below (in thousands):

The equity in earnings of White Cliffs for the year ended December 31, 2011 reported in our
consolidated statement of operations is less than 51% of the net income of White Cliffs for the same period. This is due to certain general and administrative expenses we incur in managing the operations of White Cliffs that the other owners are not
obligated to share. Such expenses are recorded by White Cliffs, and are allocated to our ownership interests. White Cliffs recorded $3.2 million of such general and administrative expense during the year ended December 31, 2011 and $0.9 million
during the three months ended December 31, 2010.

Our ownership percentage of White Cliffs is significant as defined by
Securities and Exchange Commissions Regulation S-X Rule 1-02(w). Accordingly, as required by Regulation S-X Rule 3-09, we have included the audited financial statements of White Cliffs as of and for the year ended December 31, 2011 and
the unaudited financial statements of White Cliffs as of, and for the three months ended December 31, 2010 as an exhibit to this Form 10-K.

NGL Energy

On November 1, 2011, we acquired 8,932,031 common units
representing limited partner interests in NGL Energy (which represents approximately 32.2% of the total 27,715,599 limited partner units of NGL Energy outstanding at December 31, 2011) and a 7.5% interest in the general partner of NGL Energy.
As part of this transaction, we agreed to waive our distribution rights on certain of the common units for a specified period

of time. We recorded our investment in NGL Energy at the acquisition date fair value, estimated to be $184.0 million. We derived our estimate of the fair value of our limited partner interests in
NGL Energy using the closing price of limited partner units on October 31, 2011, adjusted to reflect the waiver of certain distribution rights. At December 31, 2011, the aggregate value of our limited partner interests in NGL Energy was
approximately $177.0 million, calculated based on the closing price of the limited partner units on December 30, 2011, adjusted to reflect the waiver of distribution rights on approximately 3.9 million units until the third quarter of
2012.

The excess of the recorded amount of our investment over the book value of our share of the underlying net assets
primarily represents equity method goodwill.

At December 31, 2011, the value of our 8,932,031 common units in NGL Energy
was $184.3 million, based on a December 30, 2011 closing price of $20.63 per common unit. This does not reflect our 7.5% interest in the general partner of NGL Energy and does not include any valuation adjustment related to our agreement to
waive our distribution rights on certain of the common units for a specified period of time. Certain unaudited summarized balance sheet information of NGL Energy is shown below (in thousands):

Our policy is to record our equity in earnings of NGL Energy on a one-quarter lag, as we do not expect
information on the earnings of NGL Energy to always be available in time to consistently record the earnings in the quarter in which they are generated. Accordingly, we have not recorded any equity in earnings of NGL Energy for the period from
November 1, 2011 to December 31, 2011 in our consolidated statement of operations and comprehensive income (loss) for the year ended December 31, 2011. Certain unaudited summarized income statement information of NGL Energy for the

Canadian subsidiaries

On the Petition Date, our Canadian subsidiaries, which included SemCanada Crude, SemCAMS, and SemCanada Energy (collectively, the
Canadian Subsidiaries), filed applications for creditor protection under the CCAA in Canada. Since the CCAA proceedings were administered in a different jurisdiction than that of our petition for relief under Chapter 11 of the United
States Bankruptcy Code, we ceased to control the Canadian Subsidiaries, and accordingly we deconsolidated them on July 22, 2008. We regained control of SemCAMS and SemCanada Crude on the Emergence Date, and consolidated them again on that date.

SemGroup Energy Partners

Near the Petition Date, we lost control of SemGroup Energy Partners when certain creditors exercised their right to designate the members of the board of directors of its general partner. Also during
2008, SemGroup Holdings, L.P. (SemGroup Holdings), a wholly-owned subsidiary that held our ownership interests in SemGroup Energy Partners, filed for bankruptcy protection. SemGroup Holdings bankruptcy case was administered
separately from our bankruptcy case, and therefore we deconsolidated SemGroup Holdings and SemGroup Energy Partners. During 2009, creditors seized all of our ownership interests in SemGroup Energy Partners. SemGroup Holdings has not emerged from
bankruptcy.

| | (a) | On November 1, 2011, we contributed certain assets and liabilities of our SemStream segment to NGL Energy. On that date these assets and liabilities had the net
book values (in thousands) below. However, these values were subject to post closing adjustments, which have since been completed, and resulted in a $2.1 million working capital adjustment.

In return for this contribution, we received $93.0 million of cash and ownership interests in NGL Energy
and its general partner with an estimated fair value of $184.0 million. We recorded a gain of $44.3 million on this transaction, which includes the impact of a $2.1 million working capital

adjustment and the write-off of $1.6 million of software. Additionally, $2.2 million of capitalized loan fees were written-off as a result of long-term debt payments made from the proceeds of
this transaction.



| | (b) | We test all of our goodwill for impairment as of October 1 of each year. Upon completing this impairment test for 2011, we concluded that the goodwill and other
intangible assets attributable to the Arizona residential business of our SemStream segment (which was not contributed to NGL Energy) were impaired. To calculate the impairment loss, we estimated the fair value of this reporting unit using the
present value of estimated future cash flows, discounted at a rate of 9.4%, and recorded a full impairment of the $3.6 million balance of goodwill and the $5.0 million balance of other intangible assets associated with customer relationships. No
impairment was recorded related to the regulated assets of the Arizona residential business in accordance with FASB ASC Topic 980  Regulated Operations.

| | (c) | High crude oil prices and backwardated market conditions in 2011 had a negative effect on SemLogistics storage economics. As a result, the demand for storage is
depressed and SemLogistics has had difficulty securing contract renewals. SemLogistics successfully passed the initial 2011 goodwill impairment test. However, a review of the sensitivity of the test results indicated that a ten percent reduction in
the estimated revenue in 2012 and 2013 would result in a test failure. In addition, we received notice in late January 2012 from two customers that their intentions were not to renew their storage contracts upon expiration. These notifications,
coupled with the sensitivity of the test results to loss of revenue, led us to conclude that impairment of the goodwill of SemLogistics was required. Accordingly, we impaired the full amount of goodwill which was $44.7 million at October 1,
2011.

Year Ended December 31, 2010 (Successor)

Losses recorded during the year ended December 31, 2010 related to the disposal or impairment of long-lived assets included the
following (in thousands):

|SemMexico goodwill impairment (c)   |  | SemMexico           |  |      | (8,863  | )



| | (a) | During the year ended December 31, 2010, we revised downward our projections of the future earnings potential of the SemCanada Crude segment, following a
significant loss of customers, coupled with a significant decline in profitability and an assessment by a national consultancy firm that certain market conditions that are adversely impacting this segment were likely to continue. In response to
these events, we tested SemCanada Crudes goodwill and other intangible assets for impairment as of May 31, 2010.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

During December 2010, we completed the sale of the property, plant and equipment of the SemCanada Crude segment. The proceeds from the sale were not significantly different than the net book value of the
assets sold. Certain marketing operations in the Northern United States that were previously conducted with the participation of the SemCanada Crude segment are now being conducted in their entirety by the SemCrude segment, and the remaining
operations of the SemCanada Crude segment were wound down.

| | (b) | As described in Note 5, we sold a portion of our ownership interests in White Cliffs during September 2010. We received $140.8 million of proceeds from these
transactions, which were used to make principal payments on long-term debt. These proceeds may be adjusted upward upon final resolution of certain post-closing adjustments.

| | (c) | We test goodwill for impairment as of October 1 of each year. Upon completing this impairment test for 2010, we concluded that the goodwill attributable to our
SemMexico segment was impaired, due primarily to a decline in demand for asphalt resulting from a slowdown in road construction. To calculate the impairment loss, we estimated the fair value of the SemMexico segment using the present value of
estimated future cash flows, discounted at a rate of 13.84%.

| | * | Reported within reorganization items in the consolidated statement of operations
| | - | --------------------------------------------------------------------------------

| | (a) | We had certain natural gas gathering and processing assets that were idle or had a low volume of activity. We analyzed these assets and concluded that they were not
likely to become significantly utilized unless market conditions improved, and accordingly we recorded an impairment to reduce these assets to estimated net realizable value. This impairment reduced property, plant and equipment by $7.6 million and
reduced other intangible assets by $6.0 million.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b) | As described in Note 5, our ownership interests in SemGroup Energy Partners were seized by creditors. Our investment balance in SemGroup Energy Partners was in a
liability position, due in part to deferred gains on previous sales of limited partner interests.

|7. | DISCONTINUED OPERATIONS
|-- | -----------------------

SemFuel, SemMaterials, and SemEuro Supply are classified as discontinued operations in the consolidated statements of
operations. During 2008, we decided to sell the assets of SemMaterials and to cease the operations of SemEuro Supply, due to their losses from operations and high working capital requirements. During 2009, we decided to sell the assets of SemFuel,
due to its high working capital requirements. By December 31, 2009, the majority of the assets of SemMaterials and SemFuel had been sold.

Certain summarized information on the results of discontinued operations is shown below (in thousands):

|8. | REORGANIZATION
|-- | --------------

On July 22, 2008, we, and many of our subsidiaries, filed voluntary petitions for reorganization under Chapter 11
of the U.S. Bankruptcy Code and applications for creditor protection under the CCAA in Canada. On October 22, 2008, two more of our subsidiaries filed petitions for protection under the U.S. Bankruptcy Code. During the reorganization process,
certain claims against us in existence prior to the filing of the petitions for relief under the federal bankruptcy laws were stayed while we continued business operations as a debtor-in-possession. We received approval from the court to pay or
otherwise honor certain of our obligations incurred before the Petition Date. The court also approved our use of cash on hand at the Petition Date and cash subsequently generated through business operations to meet our post Petition Date
obligations. The court also authorized us to obtain debtor-in-possession financing.

While in bankruptcy, we filed a Plan of
Reorganization with the court, which was confirmed on October 28, 2009. The Plan of Reorganization determined, among other things, how pre-Petition Date obligations would be settled, our equity structure upon emergence, and our financing
arrangements upon emergence.

Determination of reorganization value

An essential element in negotiating a reorganization plan with the various classes of creditors is the determination of reorganization
value by the parties in interest. In the event that the parties in interest cannot agree on the reorganization value, the court may be called upon to determine the reorganization value of the entity before a plan of reorganization can be confirmed.

During the reorganization process, a reorganization value was proposed. This reorganization value was ultimately agreed to by
the creditors and confirmed by the court. The proposed reorganization value was determined by applying the following valuation methods:



| |  |  | a guideline company approach, in which valuation multiples observed from industry participants were considered and comparisons were made
between our expected performance relative to other industry participants to determine appropriate multiples to apply our financial metrics;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | analysis of recent transactions involving companies determined to be similar to us; and
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | a calculation of the present value of our estimated future cash flows.
| | - |  | ----------------------------------------------------------------------

After completing this analysis, the reorganization value was determined to be $1.5 billion. This proposed reorganization value was
determined using numerous projections and assumptions. These estimates are subject to significant uncertainties, many of which are beyond our control, including, but not limited to, the following:



| |  |  | changes in the economic environment;
| | - |  | ------------------------------------



| |  |  | changes in supply or demand for petroleum products;
| | - |  | ---------------------------------------------------



| |  |  | changes in prices of petroleum products;
| | - |  | ----------------------------------------



| |  |  | our ability to successfully implement expansion projects;
| | - |  | ---------------------------------------------------------



| |  |  | our ability to improve relationships with customers and suppliers, as these relationships were adversely impacted by the bankruptcy filing;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to renew certain business operations that were limited during the bankruptcy due to limitations on access to capital; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to manage the additional costs associated with being a public company.
| | - |  | ----------------------------------------------------------------------------------

|8. | REORGANIZATION,Continued
|-- | ------------------------



The use of different estimates could have resulted in a materially different proposed
reorganization value, and there can be no assurance that actual results will be consistent with the estimates that were used to determine the proposed reorganization value. The reorganization value confirmed by the court was utilized in the
application of fresh-start reporting.

Valuation of assets and liabilities

We recorded individual assets and liabilities based on their fair values at the Emergence Date and adjusted deferred tax liabilities where
appropriate to reflect the change in the financial reporting basis of assets. We recorded approximately $188.8 million of goodwill, which represented the excess of the reorganization value over the fair value of the identifiable assets.

| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b) | As described in Note 5, we surrendered all of our ownership interests in SemGroup Energy Partners in the reorganization process. At the time SemGroup Energy Partners
was deconsolidated, our investment balance was in a liability position, due in part to deferred gains on previous sales of limited partner interests.
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (c) | As described earlier in this Note, we revalued our assets and liabilities in fresh-start reporting, and recorded a reorganization gain for the increase in fair value of
net assets over the previously recorded value.

| | (d) | As described earlier in this Note, we reconsolidated SemCAMS and SemCanada Crude on the Emergence Date. The reorganization gain includes the excess of the fair value of
SemCAMS and SemCanada Crude upon reconsolidation over the recorded value of our investment in SemCAMS and SemCanada Crude. In addition, the reorganization gain includes the restoration of certain receivables from SemCAMS and SemCanada Crude pursuant
to their plans of reorganization.

|10. | SEGMENTS
|--- | --------

As described in
Note 1, our businesses are organized based on the nature and location of the services they provide. Certain summarized information related to our reportable segments is shown in the tables below. None of the operating segments have been aggregated,
other than White Cliffs Pipeline, which has been included within the Crude segment. Although corporate and other does not represent an operating segment, it is included in the tables below to reconcile segment information to that of the
consolidated Company. We sold the property, plant and equipment of SemCanada Crude during fourth quarter 2010 and began winding down its operations. SemCanada Crude ceased to be an operating segment during fourth quarter 2010, and is therefore
included within Corporate and other in the tables below. Eliminations of transactions between segments are also included within Corporate and other in the tables below.

The accounting policies of each segment are the same as the accounting policies of the consolidated Company. Transactions between
segments are generally recorded based on prices negotiated between the segments. Certain general and administrative and interest expenses incurred at the corporate level were allocated to the segments, based on our allocation policies in effect at
the time. During 2010, we completed a detailed study of these expenses and developed a more refined allocation methodology, which we applied to the general and administrative and interest expense allocations for the years ended December 31,
2010 and 2011.

|14. | GOODWILL AND OTHER INTANGIBLE ASSETS
|--- | ------------------------------------

Goodwill

Goodwill relates to the following segments (in thousands):



|             |  |                  |       |  |                  |   |         |

|SemStream    |  | $                |      |  |                  | $ | 53,707  | 
|SemLogistics |  |                  |      |  |                  |   | 44,220  | 
|SemMexico    |  |                  | 9,453 |  |                  |   | 9,896   | 
|             |  |                  |       |  |                  |   |         | 
|Total        |  | $                | 9,453 |  |                  | $ | 107,823 | 
|             |  |                  |       |  |                  |   |         | 

In addition to the amounts in the table above, approximately $2.9 million of our investment in NGL Energy
and its general partner and approximately $8.7 million of our investment in White Cliffs represent equity method goodwill. Our estimate of the amount of our investment in NGL Energy and its general partner that represents equity method goodwill is
subject to change, as we have not yet completed a detailed valuation analysis of the underlying assets.

As described in Note
3, we test goodwill for impairment annually, or more often if circumstances warrant. To perform these tests, we must determine which asset groups the goodwill relates to (such asset groups are referred to as reporting units). SemLogistics and
SemMexico each represent a separate reporting unit.

For the October 1, 2011 goodwill impairment tests, we developed estimates of cash
flows for each reporting unit for a period of time ranging from 9 to 15 years, and also developed an estimated terminal value using an assumed 3% growth rate (except for the SemStream residential division, for which we assumed a terminal growth rate
of 0%). We discounted the estimated cash flows to present value using a weighted average cost of capital of 13.9% for SemMexico and 9.4% for the other reporting units.

Changes in goodwill balances during the period from November 30, 2009 to December 31, 2011 are shown below (in thousands):

For U.S. federal income tax purposes, all of the goodwill recorded upon emergence from bankruptcy is being
amortized on a straight-line basis over a 15-year period with the exception of goodwill on the SemStream assets contributed to NGL Energy.

Our other intangible assets consist primarily of customer relationships and unpatented technology of our
SemMexico segment, which represented $6.0 million and $2.5 million respectively of the balance at December 31, 2011. These assets may be subject to impairments in the future if we are unable to maintain the relationships with the customers to
which the assets relate.

Prior to the Emergence Date, intangible assets were generally amortized on a straight-line basis over
the expected period of benefit. Subsequent to the Emergence Date, intangible assets are generally amortized on an accelerated basis over the estimated period of benefit. SemGroup, L.P. recorded intangible asset amortization expense from continuing
operations of $2.1 million for the eleven months ended November 30, 2009. We estimate that future amortization of other intangible assets will be as follows (in thousands):

Level 1 measurements were obtained using unadjusted quoted prices in active markets that are
accessible at the measurement date for identical, unrestricted assets or liabilities. These include commodity futures contracts that are traded on an exchange. These also include common stock warrants (Note 19), beginning in September 2011, when the
warrants began to be traded on the New York Stock Exchange.

Level 2 measurements use as inputs market observable
and corroborated prices for similar commodity derivative contracts. Assets and liabilities classified as Level 2 include over-the-counter (OTC) traded forwards contracts and swaps.

Level 3 measurements were obtained using information from a pricing service and internal valuation models incorporating
observable and unobservable market data. These include commodity derivatives, such as forwards and swaps for which there is not a highly liquid market, and therefore are not included in Level 2 above. Level 3 measurements also included common stock
warrants until September 2011, when the warrants began to be traded on the New York Stock Exchange. Prior to that point, we used a Black-Scholes pricing model to estimate the fair value of the warrants.

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. Our
assessment of the significance of a particular input to the measurement requires judgment, and may affect the valuation of assets and liabilities and their placement within the fair value levels.

Commodity derivative contracts

Our consolidated results of operations and cash flows are impacted by changes in market prices for petroleum products. This exposure to commodity price risk is managed, in part, by entering into various
commodity derivatives.

We seek to manage the price risk associated with our marketing operations by limiting our net open
positions through (i) the concurrent purchase and sale of like quantities of crude oil to create back-to-back transactions that are intended to lock in positive margins based on the timing, location or quality of the crude oil purchased and
delivered or (ii) derivative contracts. Our storage and transportation assets also can be used to mitigate location and time basis risk. All marketing activities are subject to our comprehensive risk management policy, which establishes limits
in order to manage risk and mitigate financial exposure.

As described in Note 5, we contributed the primary operating assets of SemStream to NGL
Energy on November 1, 2011, including all of SemStreams commodity derivatives. Prior to November 1, 2011, SemStream managed commodity price risk by limiting its net open positions subject to outright price risk and basis risk
resulting from grade, location or time differences. SemStream did so by selling and purchasing similar quantities of natural gas liquids with purchase and sale transactions for current or future delivery, by entering into future delivery and
purchase obligations with futures contracts or other commodity derivatives and employing its storage and transportation assets. SemStream at times hedged its natural gas liquids commodity price exposure with derivatives on commodities other than
natural gas liquids due to the limited size of the market for natural gas liquids derivatives. In addition, physical transaction sale and purchase strategies were intended to lock in positive margins for SemStream, e.g., the sales price was
sufficient to cover purchase costs, any other fixed and variable costs and SemStreams profit. All marketing activities were subject to our risk management policy, which establishes limits to manage risk and mitigate financial exposure.

Our commodity derivatives were comprised of swaps, future contracts, and forward contracts of crude oil and natural gas
liquids. These are defined as follows:

SwapsOver the counter transactions where a floating price, basis or index
is exchanged for a fixed (or a different floating) price, basis, or index at a preset schedule in the future according to an agreed-upon formula.

Futures contractsExchange traded contracts to buy or sell a commodity. These contracts are standardized by the exchange in terms of quality, quantity, delivery period and location for each
commodity.

Forward contractsOver the counter contracts to buy or sell a commodity at an agreed upon future date.
The buyer and seller agree on specific terms (price, quantity, delivery period, and location) and conditions at the inception of the contract.

The following table sets forth the notional quantities for derivative instruments entered into (amounts in thousands of barrels):

Interest rate swaps

As described in Note 17, we entered into certain interest swaps during February 2011. The swaps are recorded at fair value in other noncurrent liabilities on the consolidated balance sheet, with changes
in the fair value (net of income taxes) recorded to other comprehensive income (loss).

Concentrations of risk

During the year ended December 31, 2011, no individual customer accounted for more than 10% of our consolidated
revenue. At December 31, 2011, one customer of the SemCrude segment accounted for approximately 16% of our consolidated accounts receivable.

During the year ended December 31, 2010, no individual customer accounted for more than 10% of our consolidated revenue.

During the month ended December 31, 2009, our continuing operations generated approximately $15.8 million of revenue from one customer of the SemStream segment, which represented approximately 11% of
our consolidated revenue from continuing operations. At December 31, 2009, no individual customer accounted for more than 10% of our consolidated accounts receivable.

During the eleven months ended November 30, 2009, we generated approximately $178.4 million in revenue from one customer of the Crude segment, which represented approximately 20% of our consolidated
revenue from continuing operations. Approximately 17% of our consolidated costs of products sold were purchased from one of the Crude segments suppliers.

Employees

At December 31, 2011, we had approximately 710 employees, including approximately 480 employees outside the U.S. Approximately 106 of
the employees in Canada and Mexico are represented by labor unions and are subject to collective bargaining agreements. Of these employees, approximately 55 are subject to collective bargaining agreements that will expire in 2012 and approximately
51 expiring in 2013.



|16. | INCOME TAXES
|--- | ------------

Prior to the Emergence Date, we generally did not record a provision for U.S. federal or state income taxes since
SemGroup, L.P. was a partnership and was not subject to such taxes. Upon emergence from bankruptcy, we became a corporation and are now subject to U.S. federal and state income taxes. Our subsidiaries based in Canada, the United Kingdom, and Mexico
have been subject to income taxes in those jurisdictions throughout the period of these financial statements.

As described in
Note 5, SemCAMS and SemCanada Crude were deconsolidated from the Petition Date through the Emergence Date. Amounts shown for income (loss) from continuing operations before income taxes and for provision (benefit) for income taxes in the following
tables do not include SemCAMS and SemCanada Crude for the eleven months ended November 30, 2009.

For the eleven months ended November 30, 2009, SemGroup, L.P. was a partnership and, therefore, was
not subject to U.S. federal and state income taxes. For the month ended December 31, 2009 and the years ended December 31, 2010 and 2011, the foreign subsidiaries are disregarded entities for U.S. federal income tax purposes. The foreign
earnings are taxed in foreign jurisdictions as well as in the U.S. Foreign tax credits, subject to limitations, are available to reduce U.S. taxes.

Deferred tax positions

Deferred income taxes reflect the effects of temporary differences between the amounts of assets and liabilities recognized for financial
reporting purposes and the amounts recognized for income tax purposes. Significant components of deferred tax assets and liabilities are as follows at December 31, 2011 and 2010 (in thousands):

At December 31, 2011, we had a cumulative U.S. federal net operating loss of approximately $105.5
million that can be carried forward to apply against taxable income generated in future years. This carry forward begins to expire in 2029. We had U.S. capital losses of approximately $4.3 million and cumulative U.S. state net operating losses of
approximately $80.9 million available for carry forward, which begin to expire in 2014.

Due to our emergence from bankruptcy
and overall restructuring, we have recorded a valuation allowance on deferred tax assets. This valuation allowance decreased by $13.2 million in 2011 due primarily to a net increase in the amount of certain liabilities that have been considered as a
source of future taxable income in establishing the amount of the valuation allowance. We have not yet been able to benefit from the net operating loss and foreign tax credit carry forwards above the extent of these liabilities. The current year net
increase in the deferred tax liabilities results primarily from non-recognition of the gain recorded on the SemStream segment transaction as described in Note 6.

We have analyzed filing positions in all of the federal, state and foreign jurisdictions where we are required to file income tax returns and determined that no accruals related to uncertainty in tax
positions are required. All income tax years of the company ending after the Emergence Date remain open for examination in all

jurisdictions. In foreign jurisdictions, all tax years within the revelant statute of limitations for periods prior to the Emergence Date remain open for examination.

Income taxable to partners prior to Emergence Date

Prior to the Emergence Date, SemGroup L.P.s earnings were allocated to its general and limited partners, who were responsible for any related U.S. federal and state income taxes. Net earnings for
financial statement purposes may have differed significantly from taxable income reportable to the partners, due to differences between the tax basis and financial reporting basis of assets and liabilities and also due to the taxable income
allocation requirements under SemGroup, L.P.s partnership agreement.

Individual partners had different investment bases,
depending upon timing and price of the acquisition of partnership interests. Further, each partners tax accounting, which was dependent upon the partners tax position, may have differed from the accounting followed in the consolidated
financial statements. Accordingly, there could be significant differences between each individual partners tax basis and the partners share of the net assets reported in the consolidated financial statements. We do not have access to
information about each individual partners tax attributes, and the aggregate tax basis cannot be readily determined.

In
addition to federal income taxes, partners may have been subject to other taxes, such as state and local taxes, foreign federal and local taxes and unincorporated business taxes that may have been imposed by the various jurisdictions in which
SemGroup, L.P. conducted business or owned property. Furthermore, partners may have been required to file foreign federal income tax returns, pay foreign income taxes, file state income tax returns and pay taxes in various states.

Pro forma income tax provision (unaudited)

We estimate that, had we become a taxable corporation on January 1, 2009, the Predecessors provision for income taxes would have been $1.2 billion for the eleven months ended November 30,
2009. This estimated pro forma income tax provision assumes that the gain on extinguishment of debt in the reorganization process would have been a taxable event. The pro forma tax provision was calculated by applying an assumed U.S. federal and
state income tax rate of 35.53% to actual historical income before income taxes, taking into account estimated permanent differences. The pro forma tax provision may not be indicative of the results that actually would have occurred if we had become
a taxable corporation on January 1, 2009 or the results that may occur in the future.

SemGroup corporate credit agreement

During June 2011, we entered into a new credit agreement that consisted of a revolving facility, a Term Loan A and a Term Loan B. We used
the proceeds from the new credit facilities to retire our previous revolving credit facility and term loan, which we had entered into upon emergence from bankruptcy. Later in 2011, we retired the Term Loan A and Term Loan B on the new credit
facility, using proceeds from the contribution of SemStream assets to NGL Energy, proceeds from the Rose Rock IPO and borrowings on the revolving credit facility.

The revolving credit facility has a capacity of $320 million at December 31, 2011. This capacity may be used either for cash borrowings or letters of credit, although the maximum letter of credit
capacity is $250 million. At December 31, 2011, we had outstanding cash borrowings of $82 million on this facility and outstanding letters of credit of $12.5 million. The principal is due on June 20, 2016, and any letters of credit expire
on June 13, 2016. Earlier principal payments may be required if we enter into certain transactions to sell assets or obtain new borrowings. We have the right to make additional principal payments without incurring any penalties for early
repayment.

Interest on revolving credit cash borrowings is charged at either a Eurodollar rate or an alternate base rate, at
our election. The Eurodollar rate is calculated as:



| |  |  | the London Interbank Offered Rate (LIBOR) for U.S. dollar deposits adjusted for currency requirements; plus
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | a margin that can range from 2.5% to 4.0%, depending on a leverage ratio specified in the agreement.
| | - |  | ----------------------------------------------------------------------------------------------------

The alternate base rate is calculated as:



| |  |  | the greater of i) the U.S. Prime Rate, ii) the Federal Funds Effective Rate plus 0.5%, or iii) one-month LIBOR plus 1%; plus
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | a margin that can range from 1.5% to 3.0%, depending on a leverage ratio specified in the agreement.
| | - |  | ----------------------------------------------------------------------------------------------------

At December 31, 2011, there was $82 million of outstanding revolving cash borrowings, $75 million of which incurred interest at the
Eurodollar rate and $7 million of which incurred interest at the alternate base rate. The interest rate in effect at December 31, 2011 on the $75 million of Eurodollar rate borrowings was 3.16%, calculated as LIBOR of 0.28% plus a margin of
2.875%. The interest rate in effect at December 31, 2011 on the $7 million of alternate base rate borrowings was 5.125%, calculated as the prime rate of 3.25% plus a margin of 1.875%.

At each interest payment date, we have the option of electing whether interest will be charged at the Eurodollar rate or at the alternate
base rate for the following interest period. If we elect the alternate base rate, the following interest payment date will be at the end of the calendar quarter. If we elect the Eurodollar rate, we may elect for the next interest payment date to
occur after one, two, three, or six months, or any other period acceptable to the lenders.

Fees are charged on any outstanding
letters of credit at a rate that ranges from 2.5% to 4.0%, depending on a leverage ratio specified in the credit agreement. At December 31, 2011, the rate in effect was 2.875%. In addition, a fronting fee of 0.25% is charged on outstanding
letters of credit. A commitment fee of 0.5% is charged on any unused capacity on the revolving credit facility. In addition, we are charged an annual administrative fee of $0.1 million. We also paid $11.9 million of fees to lenders and advisors,
$5.2 million of which is attributable to the revolving credit agreement, and which was recorded in other noncurrent assets and is being amortized over the life of the agreement. The remaining $6.7 million of these fees were attributable to the term
loans, and were fully amortized during 2011.

The credit agreement includes customary affirmative and negative covenants, including
limitations on the creation of new indebtedness, liens, sale and lease-back transactions, new investments, making fundamental changes including mergers and consolidations, making of dividends and other distributions, making material changes in our
business, modifying certain documents and maintenance of a consolidated leverage ratio and an interest coverage ratio. In addition, the credit agreement prohibits any commodity transactions that are not permitted by our Comprehensive Risk Management
Policy.

The credit agreement includes customary events of default, including events of default relating to non-payment of
principal and other amounts owing under the credit agreement from time to time, including in respect of letter of credit disbursement obligations, inaccuracy of representations and warranties in any material respect when made or when deemed made,
violation of covenants, cross payment-defaults to any material indebtedness, cross acceleration to any material indebtedness, bankruptcy and insolvency events, the occurrence of a change of control, certain unsatisfied judgments, certain ERISA
events, certain environmental matters and certain assertions of or actual invalidity of certain loan documents. A default under the credit agreement would permit the participating banks to terminate commitments, require immediate repayment of any
outstanding loans with interest and any unpaid accrued fees, and require the cash collateralization of outstanding letter of credit obligations.

The credit agreement restricts our ability to make certain types of payments related to our capital stock, including the declaration or payment of dividends. The credit agreement is guaranteed by all of
our material domestic subsidiaries (except for Rose Rock Midstream Holdings, L.L.C.) and secured by a lien on substantially all of our property and assets, subject to customary exceptions. At December 31, 2011, we were in compliance with the
terms of the credit agreement.

As a condition upon the closing and effectiveness of the Rose Rock revolving credit facility,
SemGroup Corporation agreed to reduce its revolving racility commitment to $300 million within 30 days following the closing of Rose Rocks IPO.

Previous SemGroup Corporation term loan and revolving credit facilities

Pursuant to the Plan of Reorganization, on November 30, 2009, we entered into a revolving credit facility and a term loan. We retired
these facilities in June 2011 upon entering into a new credit agreement (described above). The revolving credit facility included capacity for cash borrowings and letters of credit.

We paid $27 million in fees to the lenders at the inception of the agreement, which we recorded in other noncurrent assets and amortized
over the life of the agreement.

Interest on revolving cash borrowings was charged at a floating rate, which was calculated as
5.5% plus whichever of the following yielded the highest rate: a) the Federal Funds Effective Rate plus 0.5%; b) the Prime Rate; c) the three-month LIBOR rate plus 1.5%, or d) 2.5%. In addition, a facility fee of $0.4 million was charged each year.

The facility included a fee that was payable at maturity. Interest was charged on this fee at a floating rate, which was
calculated as 7.0% plus the greater of LIBOR or 1.5%.

Certain of the letters of credit were prefunded. Fees were charged on
this prefunded tranche at a range of 7.0% to 8.5%. Fees on additional outstanding letters of credit were charged at a rate of 7.0%.

|--- | ------------------------



Fees ranging from 1.5% to 2.5% were charged on any lender commitments that we did not
utilize.

Interest was charged on the term loan at a rate of 9%. We had the option under certain circumstances to defer
interest on the term loan; when we selected this option, interest was charged during that period at a rate of 11%.

We recorded
interest expense related to these facilities of $39.3 million during the year ended December 31, 2011, $71.5 million during the year ended December 31, 2010, and $5.7 million during the month ended December 31, 2009. Included in
interest expense is the amortization of debt issuance costs of $22.2 million for the year ended December 31, 2011 (which includes a $17.4 million reduction due to the refinancing of the credit facility) and $23.6 million for the year ended
December 31, 2010.

Rose Rock credit facility

On November 10, 2011, our subsidiary Rose Rock entered into a senior secured revolving credit facility agreement. This credit
facility became effective upon completion of the Rose Rock IPO on December 14, 2011. This credit agreement provides for a revolving credit facility of $150 million. The agreement also provides that the revolving credit facility may, under
certain conditions, be increased by up to $200 million. The credit facility includes a $75 million sub-limit for the issuance of letters of credit for the account of Rose Rock or its loan parties. All amounts outstanding under the facility will be
due and payable on December 14, 2016.

At Rose Rocks option, amounts borrowed under the credit agreement will bear
interest at either the Eurodollar rate or an alternate base rate (ABR), plus, in each case, an applicable margin. Until the date the financial statements relating to the first quarter after the effective date of the credit agreement have
been delivered, the applicable margin relating to any Eurodollar loan will be 2.25% and with respect to any ABR loan will be 1.25%. After such financial statements have been delivered, the applicable margin will range from 2.25% to 3.25% in the case
of a Eurodollar rate loan, and from 1.25% to 2.25% in the case of an ABR loan, in each case, based on a leverage ratio. At December 31, 2011, there were no revolving cash borrowings.

Fees are charged on any outstanding letters of credit at a rate that ranges from 2.25% to 3.25%, depending on a leverage ratio specified
in the credit agreement. At December 31, 2011, there were $22.6 million in outstanding letters of credit, and the rate in effect was 2.25%. In addition, a fronting fee of 0.25% is charged on outstanding letters of credit.

A commitment fee that ranges from 0.375% to 0.50%, depending on a leverage ratio specified in the credit agreement, is charged on any
unused capacity of the revolving credit facility. In addition, we are charged an annual administrative fee of $0.1 million. The credit facility also allows for the use of Secured Bilateral Letters of Credit. At December 31, 2011, we had $17.0
million of Bilateral Letters of Credit outstanding and the interest rate in effect was 1.75%.

We recorded $0.1 million of
interest expense during December 2011 related to this facility, including amortization of debt issuance costs.

The credit
agreement includes customary representations and warranties and affirmative and negative covenants. The covenants in the agreement include limitations on creation of new indebtedness and liens, entry into sale and lease-back transactions,
investments, and fundamental changes including mergers and consolidations, dividends and other distributions, material changes in Rose Rocks business and modifying certain documents. The agreement also requires the maintenance of a specified
consolidated leverage ratio

and an interest coverage ratio. In addition, the agreement prohibits any commodity transactions
that are not permitted by Rose Rocks Comprehensive Risk Management Policy.

The credit agreement includes customary events of default, including events of default
relating to non-payment of principal and other amounts owing under the agreement from time to time, including in respect of letter of credit disbursement obligations, inaccuracy of representations and warranties in any material respect when made or
when deemed made, violation of covenants, cross payment-defaults of Rose Rock and its restricted subsidiaries to any material indebtedness, cross acceleration to any material indebtedness, bankruptcy and insolvency events, the occurrence of a change
of control, certain unsatisfied judgments, certain ERISA events, certain environmental matters and certain assertions of or actual invalidity of certain loan documents. A default under the Rose Rock credit agreement would permit the participating
banks to terminate commitments, require immediate repayment of any outstanding loans with interest and any unpaid accrued fees, and require the cash collateralization of outstanding letter of credit obligations.

The credit agreement restricts Rose Rocks ability to make certain types of payments relating to its capital stock, including the
declaration or payment of dividends; provided that Rose Rock may make quarterly distributions of available cash so long as no default under the agreement then exists or would result therefrom. The agreement is:



| |  |  | guaranteed by all of Rose Rocks material domestic subsidiaries; and
| | - |  | --------------------------------------------------------------------



| |  |  | secured by a lien on substantially all of the property and assets of Rose Rock and the guarantors, subject to customary exceptions.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------

At December 31, 2011, we were in compliance with the terms of the credit agreement.

SemLogistics credit facilities

SemLogistics entered into a credit agreement in December 2010, which includes a £15 million term loan and a £15 million revolving credit facility (U.S. $23.2 million each, at the
December 31, 2011 exchange rate). The proceeds from this new facility were used to retire SemLogistics previous credit facility.

The revolving credit facility can be utilized either for cash borrowings or letters of credit. The number of cash borrowings may not exceed five at any point in time and the number of outstanding letters
of credit may not exceed ten at any point in time. At December 31, 2011, no cash borrowings were outstanding under the revolving facility and no letters of credit were utilized.

Interest is charged on both the term loan and the revolving loans (including letters of credit) at a floating rate, which is calculated as
LIBOR plus a margin that ranges from 1.75% to 2.5%, depending on whether SemLogistics meets certain financial ratios specified in the agreement. The interest rate in effect at December 31, 2011 was 2.84%, which was calculated as 1.75% plus the
LIBOR rate of 1.09%. Interest on the term loan and revolving facility are payable quarterly. A commitment fee of 0.50% is charged on any unused commitments under the facility and is payable quarterly. In addition, SemLogistics paid fees of $1.3
million upon inception of the facility, which were recorded to other noncurrent assets and are being amortized over the life of the facility.

During February 2011, we entered into three interest swap agreements. The intent of the swaps is to offset a portion of the variability in interest payments due under the term loan. The swaps require us
to pay a fixed rate of 2.49% on a combined notional amount of £7.5 million (which declines during the final year of the swap until it reaches £7.0 million) each quarter through March 31, 2014. The swaps entitle us to receive a
floating rate equal to LIBOR on the same notional amount.

|--- | ------------------------



Failure to comply with the provisions of the credit agreement could cause events of
default, which could result in increases in interest rates, the debt becoming due and payable, or other adverse consequences. The events of default include the failure to pay fees, interest, or principal when due, a breach of any material
representation or warranty contained in the credit agreement, a breach of certain covenants, any default under any of the agreements entered into in connection with the loan, bankruptcy, judgments and attachments, any event of default under our
other credit agreements, default events relating to employee benefit plans, the guarantees, or collateral documents or the credit agreement failing to be in full force and effect or being declared null and void, or the occurrence of an event that is
reasonably likely to have a material adverse effect on our ability to meet our obligations under the facility. In addition, cross acceleration will occur if we do not pay any other debt facility.

SemLogistics used the proceeds from the term loan to retire its previous credit agreement, which it had entered into on November 30,
2009. The previous facility bore interest at a floating rate, which was calculated as LIBOR plus a margin ranging from 5.5% to 6.0%. In addition, SemLogistics paid $2.1 million of fees to the lender at the inception of the agreement.

SemLogistics recorded interest expense of $1.0 million for the year ended December 31, 2011, $4.0 million for the year ended
December 31, 2010, and $0.4 million for the month ended December 31, 2009, including amortization of debt issuance costs. SemLogistics recorded the fair value of the interest swaps as a noncurrent liability of $0.4 million at
December 31, 2011, with a corresponding adjustment to other comprehensive income (net of income taxes).

At
December 31, 2011, the outstanding balance of the SemLogistics credit facility has been classified as a current liability as we have committed to the banks to terminate the credit facility by March 31, 2012. The interest rate swaps will be
terminated with an expected loss on closure of £250,000 (U.S. $0.4 million at the December 31, 2011 exchange rate). At December 31, 2011, unamortized capitalized loan fees of $0.8 million were included in other assets, net on the
consolidated balance sheet.

At December 31, 2011, we were in compliance with the terms of the credit agreement.

SemCrude Pipeline credit facility

SemCrude Pipeline, L.L.C. (SemCrude Pipeline), which is a wholly-owned subsidiary that holds our ownership interest in White Cliffs, borrowed $125 million under a credit agreement on
November 30, 2009. SemCrude Pipeline retired this facility during September 2010.

Interest was generally charged on the
SemCrude Pipeline credit facility at a floating rate, which was calculated as 6% plus the greater of LIBOR or 1.5%. In addition, we paid $4.8 million in fees to the lender at the inception of the agreement, which have been fully amortized. We
recorded interest expense related to this facility of $11.0 million during the year ended December 31, 2010 and $1.1 million for the month ended December 31, 2009.

SemMexico facilities

During 2010, SemMexico entered into a credit
agreement that allowed SemMexico to borrow up to 80 million Mexican pesos at any time through June 2011. Borrowings on this facility are required to be repaid with monthly payments through May 2013. At December 31, 2011, borrowings of
56.7 million pesos (U.S. $4.0 million) were outstanding on this facility. Borrowings are unsecured and bear interest at the bank prime rate in Mexico plus 1.5%. At December 31, 2011, the interest rate in effect was 6.31%, calculated as
1.5% plus the bank prime rate of 4.81%.

|--- | ------------------------



SemMexico also has outstanding letters of credit of 210 million Mexican pesos at
December 31, 2011 (U.S. $15.0 million). Fees are generally charged on outstanding letters of credit at a rate of 0.40% for 196 million Mexican pesos (U.S. $14.0 million) in letters of credit and 1.0% for 14 million Mexican pesos (U.S.
$1.0 million) in letters of credit.

During 2011, SemMexico entered into an additional credit agreement that allows SemMexico
to borrow up to 56 million Mexican pesos (U.S. $4.0 million at the December 31, 2011 exchange rate) at any time during the term of the facility, which matures in August 2012. Borrowings would be unsecured and would bear interest at the
bank prime rate in Mexico plus 1.7%.

SemMexico recorded interest expense of $0.4 million during the year ended
December 31, 2011 related to these facilities.

At December 31, 2011, we were in compliance with the terms of these
facilities.

Scheduled principal payments

The following table summarizes the scheduled principal payments as of December 31, 2011 (in thousands). As described above, our credit agreements require accelerated principal payments under certain
circumstances. As a result, principal payments may occur earlier than shown in the table below.

Fair value

We estimate that the fair value of our long-term debt was not materially different than the recorded values at December 31, 2011. We estimate that the fair value of our fixed-rate term loan was
$316.4 million at December 31, 2010 (compared to a recorded value of $308.7 million) and that the fair value of the other (floating rate) credit agreements approximated their recorded values at December 31, 2010.

Long-term debt prior to Emergence Date

Prior to the Petition Date, SemGroup, L.P. was a borrower on several credit agreements. Substantially all of SemGroup L.P.s assets were pledged as collateral under these agreements. The bankruptcy
petitions and related events caused events of default on all of the credit agreements. In addition, the examiner appointed by the bankruptcy court alleged that certain of SemGroup L.P.s commodity trading practices prior to the Petition Date
may have violated covenants under the credit agreements.

During 2008, while under bankruptcy protection, we obtained a
debtor-in-possession credit facility to fund working capital and reorganization costs. We repaid the full balance of this facility at the Emergence Date.

All of the long-term debt prior to the Emergence Date, with the exception of certain
capital leases, was repaid, refinanced, or extinguished as part of the reorganization process.

While in bankruptcy, we only
recorded interest expense to the extent such interest was expected to be paid. Interest obligations in the amount of $221 million during the eleven months ended November 30, 2009 related to pre-petition credit agreements that were expected to
be compromised (i.e., not paid in full) in the reorganization process were not recorded as expenses.



|18. | COMMITMENTS AND CONTINGENCIES
|--- | -----------------------------

Bankruptcy matters



| | (a) | Confirmation order appeals
| | --- | --------------------------

Manchester Securities appeal.On October 21, 2009, Manchester Securities Corporation, a creditor of SemGroup Holdings, L.P.
(one of our subsidiaries), filed an objection to the Plan of Reorganization. In the objection, Manchester argued that the Plan of Reorganization should not be confirmed because it did not provide for an alleged $50 million claim of SemGroup
Holdings, L.P. against SemCrude Pipeline, L.L.C. (another of our subsidiaries). On October 28, 2009, the bankruptcy court overruled the objection and entered the confirmation order approving the Plan of Reorganization. On November 4,
2009, Manchester filed a notice of appeal of the confirmation order. On December 4, 2009, Manchesters appeal was docketed in the United States District Court for the District of Delaware. We filed a motion to dismiss the appeal as
equitably moot. On February 18, 2011, the District Court granted our motion to dismiss the appeal. On March 22, 2011, Manchester filed a notice to appeal this order. On January 2, 2012, the United States Court of Appeals affirmed the
judgment of the District Court to dismiss the appeal. Manchester has not filed a petition for rehearing or a petition for a writ of certiorari with the United States Supreme Court. The deadline for filing a petition for rehearing has passed. The
deadline for filing a petition for a writ of certiorari with the Supreme Court is March 2, 2012.

Luke Oil appeal.On October 21, 2009, Luke Oil Company, C&S Oil/Cross Properties, Inc., Wayne Thomas Oil and Gas and William R. Earnhardt Company (collectively, Luke Oil) filed an objection to the Plan of Reorganization to the extent
that the Plan of Reorganization may alter, impair, or otherwise adversely affect Luke Oils legal rights or other interests. On October 28, 2009, the bankruptcy court overruled the Luke Oil objection and entered the confirmation
order. On November 6, 2009, Luke Oil filed a notice of appeal. On December 23, 2009, Luke Oils appeal was docketed in the United States District Court for the District of Delaware. We filed a motion to dismiss the appeal as
equitably moot. Briefing on this matter is complete, but the motion to dismiss has not been ruled upon by the District Court. While we believe that this action is without merit and are vigorously defending this matter on appeal, an adverse ruling on
this action could have a material adverse impact on us.



| | (b) | Investigations
| | --- | --------------

Around
the time of our bankruptcy filings, several governmental agencies launched investigations regarding the circumstances of the filings. The mandate and scope of these investigations were very broad and the investigations are ongoing.

Bankruptcy examiner.On October 14, 2008, the bankruptcy court appointed an examiner to (i) investigate the circumstances
surrounding our trading strategy prior to bankruptcy filings; (ii) investigate the circumstances surrounding certain insider transactions and the formation of

|
|



SemGroup Energy Partners L.P. (a former subsidiary); (iii) investigate the circumstances surrounding the potential improper use of borrowed funds and funds generated from operations and the
liquidation of assets to satisfy margin calls related to our trading strategy and that of certain entities owned or controlled by former officers and directors of the general partner of SemGroup, L.P.; (iv) determine whether any directors,
officers or employees of the general partner of SemGroup, L.P. participated in fraud, dishonesty, incompetence, misconduct, mismanagement, or irregularity in the management of our affairs; and (v) determine whether the SemGroup debtor estates
have causes of action against current or former officers, directors, or employees of the general partner of SemGroup, L.P. arising from such participation. The examiners report was filed with the bankruptcy court on April 15, 2009.

Certain current and prior employees of the general partner of SemGroup, L.P. are referenced in the examiners report and
the reports conclusions may suggest possible civil or criminal liability on their part. To the extent such claims exist, they are property of a litigation trust that was established for the benefit of pre-petition creditors pursuant to the
Plan of Reorganization, and are not property of the reorganized SemGroup Corporation. This litigation trust is pursuing claims against certain former officers, at its own expense. We may incur expenses, which are not expected to be material, related
to information and document requests of the litigation trust related to such claims. Any indemnification obligations to such officers by SemGroup, L.P. were discharged under the Plan of Reorganization.

SEC.On August 5, 2008 and September 5, 2008, we received requests for voluntary production from the Securities and
Exchange Commission (SEC). On September 24, 2008, the SEC entered an Order Directing Private Investigation and Designating Officers to Take Testimony that pertains to us. The SEC has also served us with subpoenas dated
October 24, 2009, December 11, 2009 and November 15, 2010, seeking further documents and information. We complied with the SEC requests and subpoenas. On November 28, 2011, the staff of the SEC notified us that their
investigation had been completed and that they did not intend to recommend any enforcement action by the Commission.

CFTC. On June 19, 2008, we received a request for voluntary production from the Commodity Futures Trading Commission
(CFTC). Subsequent to the bankruptcy filings, the CFTC sent other requests for voluntary production. The CFTC has also served subpoenas upon us requiring us to produce various documents and for the depositions of our representatives. We
continue to comply with the CFTCs requests. We are unaware of any currently pending formal charges against us by the CFTC.

DOJ. On July 15, 2008, we received a subpoena from the Department of Justice (DOJ) directing us to produce
documents responsive to the subpoena. We contacted the DOJ regarding the subpoena and the DOJ verbally voluntarily stayed compliance with the subpoena. We have not produced any documents to the DOJ and, to our knowledge, the DOJ is not currently
pursuing any such production. We are unaware of any currently pending formal charges against us by the DOJ.



| | (c) | Claims reconciliation process
| | --- | -----------------------------

A large number of parties have made claims against us for obligations alleged to have been incurred prior to our bankruptcy filing. On September 15, 2010, the bankruptcy court entered an order
estimating the contingent, unliquidated and disputed claims and authorizing distributions to holders of allowed claims. Pursuant to that order we have begun making distributions to the claimants. We continue to attempt to settle unresolved claims.

Pursuant to the Plan of Reorganization, we committed to settle authorized and allowed bankruptcy claims by paying a specified
amount of cash, issuing a specified number of warrants, and issuing a specified number of shares of SemGroup Corporation common stock. We do not believe the resolution of the remaining outstanding claims will exceed the total amount of
consideration established under the

|--- | ---------------------------------------



Plan of Reorganization for all claimants; instead, the resolution of the remaining claims in some cases will impact the relative share of the established pool of common stock and warrants that
certain claimants receive.

However, under certain circumstances we could be required to pay additional funds to settle the
specified group of claims to be settled with cash. Pursuant to the Plan of Reorganization, a specified amount of restricted cash was set aside at the Emergence Date, which we expect to be sufficient to settle this group of claims. Since the
Emergence Date, we have made significant progress in resolving these claims, and we continue to believe that the cash set aside at the Emergence Date will be sufficient to settle these claims. However, we have not yet reached a resolution of
all of these claims, and if the total settlement amount of all of these claims exceeds the specified amount, we will be required to pay additional funds to satisfy the total settlement amount for this specified group of claims. If this were to
become probable of occurring, we would be required to record a liability and a corresponding expense.

Blueknight claim

Blueknight Energy Partners, L.P. (Blueknight), which was formerly a subsidiary of SemGroup, together with
other entities related to Blueknight, entered into a Shared Services Agreement on April 7, 2009, with SemCrude, L.P. and SemManagement, L.L.C. (which are currently subsidiaries of SemGroup). The services provided by SemCrude to Blueknight under
this agreement included the coordination of movement of crude oil belonging to Blueknights customers and the operation of Blueknights Oklahoma pipeline system and its Cushing, Oklahoma terminal. Under the subsequent amendments to the
agreements beginning in May 2010, certain of these services were phased out, and Blueknight began to manage the movement of its crude oil and the operation of its Cushing terminal.

In a letter dated August 18, 2011, Blueknight claimed that SemCrude owes Blueknight approximately 141,000 barrels of crude oil. We
responded to Blueknights letter denying their charges and requesting documentation from Blueknight of its claim. We continued to respond to requests for information and to review documentation provided by Blueknight; however, on
February 14, 2012, Blueknight filed suit against us, Rose Rock Midstream GP, L.L.C. and Rose Rock Midstream, L.P. in the District Court of Oklahoma County, Oklahoma in connection with this claim. We continue to maintain that there is no basis
for their claim and will vigorously defend this matter; however, we cannot reliably predict the outcome.

Other matters

We are party to various other claims, legal actions, and complaints arising in the ordinary course of business. In the
opinion of our management, the ultimate resolution of these claims, legal actions, and complaints, after consideration of amounts accrued, insurance coverage, and other arrangements, will not have a material adverse effect on our consolidated
financial position, results of operations or cash flows. However, the outcome of such matters is inherently uncertain, and estimates of our consolidated liabilities may change materially as circumstances develop.

Environmental

We may from time to time experience leaks of petroleum products from our facilities, as a result of which we may incur remediation obligations or property damage claims. In addition, we are subject to
numerous environmental regulations. Failure to comply with these regulations could result in the assessment of fines or penalties by regulatory authorities.

The Kansas Department of Health and Environment (the KDHE) initiated
discussions during our bankruptcy proceeding regarding six of our sites in Kansas (five owned by SemCrude and one owned by SemGas) that KDHE believes, based on their historical use, may have soil or groundwater contamination in excess of state
standards. KDHE sought our agreement to undertake assessments of these sites to determine whether they are contaminated. We reached an agreement with KDHE on this matter and entered into a Consent Agreement and Final Order with KDHE to conduct
environmental assessments on the sites and to pay KDHEs costs associated with their oversight of this matter. We have conducted phase II investigations at all sites. Four of the six sites have limited amounts of soil contamination that will be
excavated and/or remediated on site. Four of the six sites appear to have ground water contamination that may require further delineation and/or on-going monitoring. We are preparing work plans to submit to the State of Kansas for approval. We do
not anticipate any penalties or fines for these historical sites.

A water pipeline break occurred at a SemCAMS facility during
August 2010. This resulted in a spill of material that was predominantly salt water containing a small amount of hydrocarbons. The incident was investigated by Environment Canada and Alberta Environment. On February 14, 2012, charges were filed
against SemCAMS by the Federal Government of Canada (Department of Fisheries) and the Province of Alberta (Alberta Environment) in connection with this incident. SemCAMS is summoned to appear in court in Fox Creek, Province of Alberta to respond to
the charges. We are currently reviewing the charges and will request disclosure from the agencies in order to determine our response. Although it is not possible to predict the outcome of these proceedings, we accrued a liability for estimated fines
and environmental contributions of $0.4 million in December 2010 which we still carry on our books at December 31, 2011.

Asset retirement obligations

We will be required to incur significant removal and restoration costs when we retire our natural gas gathering and processing facilities in Canada. We have recorded a liability associated with these
obligations, which is reported within other noncurrent liabilities on the consolidated balance sheets. The following table summarizes the changes in this liability from November 30, 2009 (the date we reconsolidated SemCAMS) through
December 31, 2011 (in thousands):

The December 31, 2011 liability was calculated using the $105.3 million cost we estimate we would
incur to retire these facilities, discounted based on our risk-adjusted cost of borrowing and the estimated timing of remediation.

The calculation of the liability for an asset retirement obligation requires the use of
significant estimates, including those related to the length of time before the assets will be retired, cost inflation over the assumed life of the assets, actual remediation activities to be required, and the rate at which such obligations should
be discounted. Future changes in these estimates could result in material changes in the value of the recorded liability. In addition, future changes in laws or regulations could require us to record additional asset retirement obligations. The
$105.3 million estimated cost represents only our proportionate share of the obligations associated with these facilities. An additional $44.2 million of estimated costs are attributable to third-party owners proportionate share of the
obligations. If an owner fails to perform on its obligations, the other owners (including SemGroup) could be obligated to bear that partys share of the remediation costs.

Our other segments may also be subject to removal and restoration costs upon retirement of their facilities. However, we do not believe the present value of such obligations under current laws and
regulations, after taking into account the estimated lives of our facilities, is material to our financial position or results of operations.

Leases

We have entered into capital and operating lease agreements for
office space, office equipment, land, trucks and tank storage. Future minimum payments required under operating leases that have initial or remaining non-cancelable lease terms in excess of one year at December 31, 2011 are as follows (in
thousands):

Purchase and sale commitments

We routinely enter into agreements to purchase and sell petroleum products at specified future dates. We account for these commitments as
normal purchases and sales, and therefore we do not record assets or liabilities related to these agreements until the product is purchased or sold. At December 31, 2011, such commitments included the following (in thousands):



|                         |  |                      |        |  |           |  |           |

Certain of the commitments shown in the table above relate to agreements to purchase product from a
counterparty and to sell a similar amount of product (in a different location) to the same counterparty. Many of the commitments shown in the table above are cancellable by either party, as long as notice is given within the time frame specified in
the agreement (generally 30 to 120 days).

In addition, our SemGas segment enters into contracts under which we are responsible
for marketing the majority of the gas and natural gas liquids produced by the counterparties to the agreements. In 2011, the majority of SemGas revenues were generated from such contracts.

Common stock

Upon emergence from bankruptcy, we issued 40,882,496 shares of common stock. The Plan of Reorganization specified that we were to issue an additional 517,500 shares of common stock in settlement of
pre-petition claims. As of December 31, 2011, we have issued 182,174 shares of this stock and will issue the remainder as the process of resolving the claims progresses. The owners equity balances on the consolidated balance sheets
include the shares that are required to be issued in settlement of pre-petition claims. The shares of common stock reflected on the consolidated balance sheet at December 31, 2011 are summarized below:

In addition to the shares in the table above, there are shares of unvested restricted stock outstanding at
December 31, 2011. The par value of these shares has not yet been reflected in common stock on the consolidated balance sheet, as these shares have not yet vested. There are also shares of restricted stock that were returned to treasury upon
forfeiture. The par value of these shares is not reflected in the consolidated balance sheet, as no accounting recognition is given to forfeited shares.

The common stock includes Class A and Class B stock. Class A stock is eligible
to be listed on an exchange, whereas Class B stock is not. Any share of Class B stock may be converted to Class A at the election of the holder. Both classes of stock have full voting rights. Both classes of stock have a par value of $0.01 per
share. The total number of shares authorized for issuance is 90,000,000 shares of Class A stock and 10,000,000 shares of Class B stock.

On October 28, 2011, we adopted a limited duration Stockholders Rights Plan (the Rights Plan) and declared a dividend of one right on each outstanding share of our Class A common
stock. Under the Rights Plan, the rights generally will become exercisable only if a person or group acquires beneficial ownership of 10% or more of our Class A common stock in a transaction not approved by our Board of Directors. In that
situation, each holder of a right (other than the acquiring person, whose rights will become void and will not be exercisable) will be entitled to purchase, at the then-current price, additional shares of Class A common stock having a value of
twice the exercise price of the right. In addition, if we are acquired in a merger or other business combination after an unapproved party acquires more than 10% of our Class A common stock, each holder of the right would then be entitled to
purchase, at the then-current exercise price, shares of the acquiring companys stock having a value of twice the exercise price of the right. We may redeem the rights for $0.001 per right at any time before an event that causes the rights to
become exercisable. Under the Rights Plans terms, the rights will expire one day after the date of our 2012 Annual Meeting of Stockholders.

Warrants

Upon emergence from bankruptcy protection, we issued 1,634,210
warrants. The Plan of Reorganization specified that we were to issue an additional 544,737 warrants in settlement of the pre-petition claims. As of December 31, 2011, we have issued 191,752 of the warrants and will issue the remainder as the
process of resolving the claims progresses. Beginning September 2011, the warrants began trading on the New York Stock Exchange under the ticker symbol, SEMGWS. The warrants reflected on the consolidated balance sheet at December 31, 2011 are

Each warrant entitles the holder to purchase one share of common stock for $25 at any time before the
November 30, 2014 expiration date. Upon exercise, a holder may elect a cashless exercise, whereby the number of shares to be issued to the holder is reduced, in lieu of a cash payment. The closing price of our common stock was $26.06 per share
on December 31, 2011. In the event of a change in control of the Company, the holders of the warrants would have the right to sell the warrants to us, and we would have the right to purchase the warrants from the holders. In either case, the
price to be paid for the warrants would be calculated using a standard pricing model with inputs specified in the warrants agreement.

Since we experienced losses from continuing operations during the year ended December 31, 2010 and
the month ended December 31, 2009, the share-based compensation (described in Note 21) did not cause any dilution for these periods.

For the year ended December 31, 2011, we recorded a gain on the change in the fair value of the warrants of $5 million which creates a loss from continuing operations when excluded from the numerator
for the calculation of diluted EPS for the period. For the year ended December 31, 2010, we recorded a loss on the change in the fair value of the warrants; because of this, the warrants did not cause any dilution for that period. For the month
ended December 31, 2009, the average price of our common stock was at or below the exercise price of the warrants, and therefore the warrants did not cause any dilution for that period.

On January 11, 2012, we issued 91,712 shares of common stock upon the vesting of certain grants of restricted stock and restricted
stock units. These shares are not reflected in the shares of common stock shown in the tables above.

|21. | EQUITY-BASED COMPENSATION
|--- | -------------------------

SemGroup Corporation (Successor) equity awards

We have reserved a total of 2,781,635 shares of common stock for issuance pursuant to employee and director compensation programs. Upon
emergence from bankruptcy, we began issuing awards of restricted stock and restricted stock units pursuant to such programs. These awards give the recipients the right to receive shares of common stock, once specified service or performance related
vesting conditions are met. We record expense for these awards (and corresponding increases to additional paid-in capital) based on the grant date fair value of the awards. Although these awards are to be settled in shares, we may elect to give
participants the option of settling a portion of the awards in cash, to meet statutory minimum tax withholding requirements. The activity related to these awards is summarized below:

Restricted stock granted subsequent to December 31, 2011

During first quarter 2012, we granted approximately 131,700 awards of restricted stock and restricted stock units that will vest on
January 19, 2015, contingent upon the continued service of the recipients. Also during the first quarter 2012, we granted certain restricted stock awards that will vest in 2015, contingent not only on the continued service of the recipients,
but also on our achievement of certain specified targets. The maximum number of these awards that could vest is approximately 128,650 shares, if we meet the specified maximum performance targets.

Retention Awards

During June 2010, we granted retention awards to certain officers and employees, which were scheduled to vest in December 2011, contingent on the continued service of the recipients. Each award had a
specified value that was payable either in cash or in shares of SemGroup stock.

We recorded $2.4 million of expense during
2011 and $2.0 million of expense during 2010 related to these retention awards. Upon vesting during 2011, we settled awards with a value of $1.2 million by paying cash, and we settled awards with a value of $3.2 million by issuing 125,212 shares of
common stock.



|22. | EMPLOYEE BENEFIT PLANS

Defined contribution plans

We sponsor defined contribution retirement plans in which the majority of employees are eligible to participate. SemGroup Corporations contributions to the defined contribution plans were $1.1
million for the year ended December 31, 2011, $1.3 million for the year ended December 31, 2010, and $0.1 million for the month ended December 31, 2009. SemGroup, L.P.s contributions to the defined contribution plans related to

To compute the December 31, 2011 projected benefit obligation of the Pension Plans, we used a
discount rate of 4.25% and an assumed rate of compensation increase of 3.5%. To compute the December 31, 2010 projected benefit obligation of the Pension Plans, we used a discount rate of 5.25% and an assumed rate of compensation increase of
4%.

We recorded other noncurrent liabilities of $5.8 million at December 31, 2011, and $5.1 million at December 31,
2010, to reflect the funded status of the Pension Plans. We recorded changes in the funded status of the Pension Plans to other comprehensive income (loss), net of income taxes. These amounts were a loss of $1.7 million for the year ended
December 31, 2011, a loss of $2.0 million for the year ended December 31, 2010, and a gain of $0.8 million for the month ended December 31, 2009.

The following table summarizes the components of the net periodic benefit cost related

To compute interest cost, we used discount rates of 5.25%, 6.00% and 5.75% for 2011, 2010 and 2009,
respectively. To compute expected return on plan assets, we used an estimated rate of return of 6.75% for 2011 and 7.00% for 2010 and 2009.

We estimate that benefit payments from the Pension Plans will be as follows for the years 2012  2021 (in thousands):

|2017 - 2021 |  |                           | 9,452 | 

We estimate that we will make contributions of $1.1 million to the Pension Plans during the year ended
December 31, 2012.

Substantially all of the plans assets are invested in pooled funds that hold highly-liquid
securities. The value of each share of a pooled fund is calculated based on the quoted market prices of the assets held by the fund. The following table shows the value of each category of plan assets at December 31, 2011 and 2010 and the
target investment allocation under our investment policy at December 31, 2011:

|22. | EMPLOYEE BENEFIT PLANS,Continued
|--- | --------------------------------



Our investment policy for plan assets permits investments in a wide variety of assets,
including certain types of derivatives. Our policy prohibits investments of plan assets in certain types of assets, including commodities, mineral rights, and collectibles. Our investment policy requires us to maintain an investment allocation
within the ranges shown in the table above, and also contains more specific requirements that are designed to achieve an appropriate level of diversification. The fair values of the pension plans pooled funds are level 2 measurements, while
the fair value of the cash and cash equivalents component of plan assets is a level 1 measurement.

Retiree medical plan

We sponsor an unfunded, post-employment health benefit plan (the Health Plan) for certain employees of the
SemCAMS segment. The projected benefit obligation related to the Health Plan was $1.7 million at December 31, 2011 and $1.7 million at December 31, 2010, and is reported within other noncurrent liabilities on the consolidated balance
sheets.

Termination benefits

The laws in Canada, the United Kingdom and Mexico require us to pay certain benefits to employees if their employment is terminated without cause. In addition, we entered into agreements with certain
employees in the U.S. that would require us to pay benefits to those employees if their employment is terminated without cause before June 2, 2012. We recorded $1.6 million of expense during 2010 and $0.4 million of expense during 2011 for
termination benefits related to the wind-down of certain operations of SemCanada Crude.
