Cautionary Note Regarding Forward-Looking Statements

Certain matters contained in this Form 10-Q include “forward-looking statements.” All statements, other than statements of historical fact, included in this Form 10-Q regarding the prospects of our industry, our anticipated financial performance, 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,” “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 Part II, Item 1A of our most recent Annual Report on Form 10-K, entitled “Risk Factors,” risk factors discussed in other reports that we file with the Securities and Exchange Commission (the “SEC”), and the following:

• Our ability to generate sufficient cash flow from operations to enable us to pay the minimum quarterly distribution to holders of our common units, general partner units and subordinated units;

• Our profitability depends on the demand for crude oil in the markets we serve;

• Our ability to obtain new sources of crude oil;

• Restrictions in our revolving credit facility could adversely affect our business, results of operations, financial condition and ability to make cash distributions to our unitholders;

• Our future debt may limit our flexibility to obtain financing and pursue business opportunities;

• The credit profile of SemGroup Corporation could adversely affect our credit rating which could increase our borrowing costs;

• Our ability to renew or replace expiring storage contracts;

• The loss or nonpayment by one of our key customers could adversely affect our business, results of operations, financial condition and our ability to make cash distributions to our unitholders;

• Our ability to minimize risk exposure associated with the marketing of crude oil; and

• Our preparedness towards the many hazards and operational risks associated with our business, many of which may not be covered by insurance.

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.

Readers are cautioned not to place undue reliance on any forward-looking statements contained in this Form 10-Q, which reflect management’s opinions only as of the date hereof. Except as required by law, we undertake no obligation to revise or publicly release the results of any revision to any forward-looking statements.

As used in this Form 10-Q, and unless the context indicates otherwise, the terms (i) the “Partnership,” “Rose Rock,” “we,” “our,” “us” or like terms, refer to Rose Rock Midstream, L.P., its subsidiaries and its predecessor; (ii) “SemGroup” refers to SemGroup Corporation (NYSE: SEMG), SemGroup, L.P., and their subsidiaries and affiliates, other than our general partner and us; (iii) “Rose Rock GP” or our “general partner” refer to Rose Rock Midstream GP, LLC; and (iv) “unitholders” refer to our common and subordinated unitholders, and not our general partner.

Notes to Unaudited Condensed Consolidated Financial Statements

1. OVERVIEW

Rose Rock Midstream, L.P. is a Delaware limited partnership. Rose Rock Midstream, L.P. was formed in August 2011. On November 29, 2011, SemGroup Corporation contributed a wholly-owned subsidiary, Rose Rock Midstream Crude, L.P. (formerly known as SemCrude, L.P.), to Rose Rock Midstream, L.P., in return for limited partner interests, general partner interests, and certain incentive distribution rights in Rose Rock Midstream, L.P. On December 14, 2011, Rose Rock Midstream, L.P. completed an initial public offering in which it sold 7,000,000 common units representing limited partner interests.

The general partner of Rose Rock Midstream, L.P. is Rose Rock Midstream GP, LLC, which is a wholly-owned subsidiary of SemGroup Corporation. SemGroup Corporation is a Delaware corporation headquartered in Tulsa, Oklahoma that provides diversified midstream services to the energy industry. SemGroup Corporation is the successor entity of SemGroup, L.P., which was an Oklahoma limited partnership.

The terms “we,” “our,” “us,” “Rose Rock,” the “Partnership” and similar language used in these notes to the unaudited condensed consolidated financial statements refer to Rose Rock Midstream, L.P, its subsidiaries, and its predecessor. The term “SemGroup” refers to SemGroup Corporation, SemGroup, L.P., and their other controlled subsidiaries, including Rose Rock Midstream GP, LLC.

Basis of presentation

These condensed consolidated financial statements of Rose Rock Midstream, L.P. include the activity of its predecessor prior to November 29, 2011. The predecessor included Rose Rock Midstream Crude, L.P. (“Rose Rock Crude”), a wholly-owned subsidiary of SemGroup Corporation (exclusive of Rose Rock Crude’s ownership interests in SemCrude Pipeline, L.L.C., which holds a 51% ownership interest in the White Cliffs Pipeline). Subsequent to November 29, 2011, these condensed consolidated financial statements include the accounts of Rose Rock Midstream, L.P. and its controlled subsidiaries, which include Rose Rock Crude.

These condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and the rules and regulations of the SEC. These condensed consolidated financial statements include all normal and recurring adjustments that, in the opinion of management, are necessary to present fairly the financial position of the Company and the results of its operations and its cash flows. All significant transactions between Rose Rock Midstream, L.P. and its consolidated subsidiaries have been eliminated.

These condensed consolidated financial statements are unaudited. The condensed consolidated balance sheet at December 31, 2011 is derived from audited financial statements.

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. Although management believes these estimates are reasonable, actual results could differ materially from these estimates. The results of operations for the three months ended March 31, 2012 are not necessarily indicative of the results to be expected for the full year ending December 31, 2012.

Pursuant to the rules and regulations of the SEC, the accompanying condensed consolidated financial statements do not include all of the information and notes normally included with financial statements prepared in accordance with accounting principles generally accepted in the United States. These condensed consolidated financial statements should be read in conjunction with the audited condensed consolidated financial statements and notes thereto for the year ended December 31, 2011, which are included in our Annual Report on Form 10-K for the year ended December 31, 2011, filed with the SEC.

1. OVERVIEW, Continued

SemGroup bankruptcy

On July 22, 2008 (the “Petition Date”), SemGroup, L.P., SemCrude, L.P. (“SemCrude”), and Eaglwing, L.P. (“Eaglwing”) filed petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code. 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”). 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, SemCrude, and Eaglwing emerged from bankruptcy protection on November 30, 2009 (the “Emergence Date”).

Recent accounting pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standards (IFRS),” which creates common fair value measurement and disclosure requirements in U.S. GAAP and IFRS. We adopted this guidance on January 1, 2012. The impact of adoption was not material.

2. FINANCIAL INSTRUMENTS

Commodity derivative contracts

Our 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.

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

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.

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.

We record certain commodity derivative assets and liabilities at fair value at each balance sheet date. The table below summarizes the balances of these assets and liabilities at March 31, 2012 and December 31, 2011 (in thousands):

	March 31, 2012
	Level 1		Netting*			Total
Assets	$	24	$	(8	)	$	16
Liabilities		8		(8	)		—
Net assets at fair value	$	16	$	—		$	16

	December 31, 2011
	Level 1		Netting*			Total
Assets	$	393	$	(231	)	$	162
Liabilities		231		(231	)		—
Net assets at fair value	$	162	$	—		$	162

* Relates primarily to exchange traded futures. Gain and loss positions on multiple contracts are settled net on a daily basis with the exchange.

“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 futures contracts that are traded on an exchange.

“Level 2” measurements use as inputs market observable and corroborated prices for similar derivative contracts. Assets and liabilities classified as Level 2 include over-the-counter (OTC) traded physical fixed priced purchases and sales forward contracts.

“Level 3” measurements were obtained using information from a pricing service and internal valuation models incorporating observable and unobservable market data. For 2011, these included physical fixed price purchases and sales forward contracts with an affiliate for which there was not a highly liquid OTC market, and therefore were not included in Level 1 or Level 2 above.

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. At March 31, 2012, all of our physical fixed price forward purchases and sales contracts were being accounted for as normal purchases and normal sales.

There were no financial assets or liabilities classified as Level 3 during the three months ended March 31, 2012. The following table reconciles changes in the fair value of commodity derivatives classified as Level 3 in the fair value hierarchy (in thousands):

	Three Months Ended March 31, 2012		Three Months Ended March  31, 2011
Beginning balance	$	—	$	1,619
Total gain (realized and unrealized) included in product revenues		—		2,168
Settlements		—		(1,337	)
Ending balance	$	—	$	2,450
Amount of total gain included in earnings for the period attributable to the change in unrealized gain or loss relating to assets and liabilities still held at the reporting date	$	—	$	2,450

Purchases		451		3,533

We have not designated any of our commodity derivative instruments as accounting hedges. We record the fair value of the derivative instruments on our condensed consolidated balance sheets in other current assets and other current liabilities. The fair value of our commodity derivative assets and liabilities recorded to other current assets and other current liabilities was as follows (in thousands):

	March 31, 2012				December 31, 2011
	Assets		Liabilities		Assets		Liabilities
Commodity contracts	$	16	$	—	$	162	$	—

Realized and unrealized gains (losses) from our commodity derivatives were recorded to product revenue in the following amounts (in thousands):

	Three Months Ended March 31, 2012			Three Months Ended March 31, 2011
Commodity contracts	$	(1,125	)	$	810

3. LONG-TERM DEBT

On November 10, 2011, we entered into a five-year senior secured revolving credit facility agreement. The credit facility under this agreement became effective upon completion of our initial public offering on December 14, 2011.

The 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 an additional $200 million. The credit facility includes a $75 million sub-limit for the issuance of letters of credit. All amounts outstanding under the agreement will be due and payable on December 14, 2016.

At our 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 quarter ending March 31, 2012 have been delivered, the applicable margin relating to any Eurodollar rate 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 March 31, 2012, we did not have any outstanding borrowings on this facility.

Notes to Unaudited Condensed Consolidated Financial Statements

3. LONG-TERM DEBT,Continued

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 March 31, 2012, there were $29.8 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, which are issued external to the credit facility and do not reduce revolver availability. At March 31, 2012, we had $9 million of Secured Bilateral Letters of Credit outstanding and the interest rate in effect was 1.75%.

We paid $1.7 million in fees to lenders and advisors which was recorded in other noncurrent assets and is being amortized over the life of the agreement. We recorded $0.5 million of interest expense during the three months ended March 31, 2012 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 our business and modifying certain documents. The agreement also requires the maintenance of a specified consolidated leverage ratio of no more than 4.5 to 1.0 (or 5.0 to 1.0 during a temporary period from the date of funding of the purchase price of certain acquisitions (as described in the credit facility) until the last day of the third fiscal quarter following such acquisitions) and an interest coverage ratio of no less than 2.5 to 1.0. In addition, the 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 agreement from time to time, including in respect to 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 us and our 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 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 relating to our units, including the declaration or payment of cash distributions, provided that we 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 our material domestic subsidiaries and secured by a lien on substantially all of our property and assets, subject to customary exceptions. At March 31, 2012, we were in compliance with the terms of the credit agreement.

At March 31, 2012, we had $80 thousand of capital lease obligations reported as long-term debt on the consolidated balance sheet.

4. 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. (a subsidiary of SemGroup), 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. On October 28, 2009, the bankruptcy court overruled the objection and entered the confirmation order approving the Plan of Reorganization.

4. COMMITMENTS AND CONTINGENCIES, Continued

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. SemGroup filed a motion to dismiss the appeal as equitably moot. On February 18, 2011, the District Court granted SemGroup’s 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 and the deadline for filing any petition for re-hearing or review has passed without further action by Manchester.

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. SemGroup 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 SemGroup believes that this action is without merit and is vigorously defending this matter on appeal, an adverse ruling on this action could have a material adverse impact on us. Rose Rock is indemnified by SemGroup against any loss in this matter pursuant to the terms of the omnibus agreement.

(b) Claims reconciliation process

A large number of parties have made claims against SemGroup for obligations alleged to have been incurred prior to the Petition Date. 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 SemGroup has begun making distributions to the claimants. SemGroup continues to attempt to settle unresolved claims.

Pursuant to the Plan of Reorganization, SemGroup committed to settle all pre-petition 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. The resolution of most of the outstanding claims will not impact the total amount of consideration SemGroup will give to the claimants; instead, the resolution of the claims will impact the relative share of the total consideration that each claimant receives.

However, there is a specified group of claims for which SemGroup could be required to pay additional funds to settle. Pursuant to the Plan of Reorganization, SemGroup set aside a specified amount of restricted cash at the Emergence Date, which SemGroup expected to be sufficient to settle this group of claims. Since the Emergence Date, SemGroup has made significant progress in resolving these claims, and continues to believe that the cash set aside at the Emergence Date will be sufficient to pay these claims. However, SemGroup has not yet reached a resolution of all of these claims, and if the total settlement amount of these claims exceeds the specified amount, SemGroup will be required to pay additional funds to these claimants, and we could be required to share in this expense. Rose Rock is indemnified by SemGroup against any loss in this matter pursuant to the terms of the omnibus agreement.

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 (“KDHE”) initiated discussions during SemGroup’s bankruptcy proceeding regarding five of our sites in Kansas that KDHE believed, 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. SemGroup 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. SemGroup has

Notes to Unaudited Condensed Consolidated Financial Statements

4. COMMITMENTS AND CONTINGENCIES,Continued

conducted phase II investigations at all sites. Three of the five sites have limited amounts of soil contamination that will be excavated and/or remediated on site. Three of the five sites appear to have ground water contamination that may require further delineation and/or on-going monitoring. Work plans have been submitted to, and approved by, the KDHE. Rose Rock is indemnified by SemGroup against any loss in this matter pursuant to the terms of the omnibus agreement.

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. SemGroup responded to Blueknight’s letter denying their charges and requesting documentation from Blueknight of its claim. SemGroup continued to respond to requests for information and to review documentation provided by Blueknight. On February 14, 2012, Blueknight filed suit against SemGroup in the District Court of Oklahoma County, Oklahoma in connection with this claim. On May 1, 2012, the court approved our motion to transfer this case to Tulsa County, Oklahoma. SemGroup believes this matter is without merit and will vigorously defend their position; however, SemGroup cannot reliably predict the outcome. Rose Rock is indemnified by SemGroup against any loss in this matter pursuant to the terms of the omnibus agreement.

Asset retirement obligations

We may be subject to removal and restoration costs upon retirement of our facilities. However, we are unable to predict when, or if, our pipelines, storage tanks and related facilities would become completely obsolete and require decommissioning. Accordingly, we have not recorded a liability or corresponding asset, as both the amount and timing of such potential future costs are indeterminable.

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 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.

Purchase and sale commitments

We routinely enter into agreements to purchase and sell petroleum products at specified future dates. We create a margin for these purchases by entering into various types of physical and financial sales and exchange transactions through which we seek to maintain a position that is substantially balanced between purchases on the one hand and sales and future delivery obligations on the other. 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 March 31, 2012, such commitments included the following (in thousands):

	Volume (barrels)		Value
Fixed price purchases		53	$	4,975
Fixed price sales		128	$	13,382
Floating price purchases		31,585	$	3,240,715
Floating price sales		31,846	$	3,330,409

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.

Balance at March 31, 2012	$	130,295		$	38,274		$	136,728		$	6,229		$	311,526

Distribution rights

We intend to pay a minimum quarterly distribution of $0.3625 per unit, to the extent we have sufficient cash from operations after establishment of cash reserves and payment of fees and expenses, including payments to our general partner and its affiliates. We refer to this cash as “available cash,” and it is defined in our partnership agreement. Our ability to pay the minimum quarterly distribution is subject to various restrictions and other factors.

Our partnership agreement requires that we distribute all of our available cash each quarter in the following manner:

• first,98.0% to the holders of common units and 2.0% to our 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 our 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 our general partner, until each unit has received a distribution of $0.416875.

If cash distributions to our unitholders exceed $0.416875 per unit in any quarter, our general partner will receive, in addition to distributions on its 2.0% general partner interest, increasing percentages, up to 48.0%, of the cash we distribute in excess of that amount. We refer to these distributions as “incentive distributions.” The following table summarizes the incentive distribution levels:

			Marginal Percentage Interest in Distributions
	Total Quarterly Distribution Per Unit Target Amount		Unitholders			General Partner Interest			Incentive Distribution Rights
Minimum Quarterly Distribution		$0.3625		98.0	%		2.0	%		—
First Target Distribution	above $0.3625	up to $0.416875		98.0	%		2.0	%		—
Second Target Distribution	above $0.416875	up to $0.453125		85.0	%		2.0	%		13.0	%
Third Target Distribution	above $0.453125	up to $0.54375		75.0	%		2.0	%		23.0	%
Thereafter		above $0.54375		50.0	%		2.0	%		48.0	%

5. PARTNERS’ CAPITAL AND DISTRIBUTIONS, Continued

Distribution declared in January 2012

On January 23, 2012, we declared a distribution of $0.0670 (calculated as the $0.3625 minimum quarterly distribution, prorated based on the length of time during the three months ended December 31, 2011, that was subsequent to our initial public offering). This distribution was paid on February 13, 2012 to unitholders of record as of February 3, 2012.

Distribution declared in April 2012

On April 24, 2012, we declared a distribution of $0.3725 per unit, or $1.49 per unit on an annualized basis. This is a 2.8% increase over the prior quarter on an annualized basis and marks the first increase in the distribution to our limit partner unitholders. This distribution will be paid on May 15, 2012 to all unitholders of record as of May 7, 2012.

Equity incentive plan

On December 8, 2011, the board of directors of our general partner adopted the Rose Rock Midstream Equity Incentive Plan (the “Incentive Plan”). We have reserved 840,000 limited partner common units for issuance to non-management directors and employees under the Incentive Plan. At March 31, 2012, there are 38,359 unvested restricted unit awards that have been granted pursuant to the Incentive Plan. Generally, the awards vest three years after the date of grant for employees and one year after the date of grant for non-management directors, contingent upon the continued service of the recipients and may be subject to accelerated vesting in the event of involuntary terminations.

The holders of these restricted units are entitled to equivalent distributions (“Unvested Unit Distributions” or “UUD’s”) to be received upon vesting of the restricted unit awards. The distributions will be settled in common units based on the market price of our limited partner common units as of the close of business on the vesting date. The UUD’s are subject to the same forfeiture and acceleration conditions as the associated restricted units. At March 31, 2012, the value of the UUD’s was approximately $2.5 thousand. This is equivalent to approximately 107 common units based on the quarter end close of business market price of our common units of $23.84 per unit.

6. EARNINGS PER LIMITED PARTNER UNIT

Net income is allocated to the general partner and the limited partners in accordance with their respective partnership percentages, after giving effect to any priority income allocations for incentive distributions that are allocated to the general partner.

Basic and diluted earnings per limited partner unit is determined by dividing net income allocated to the limited partners by the weighted average number of limited partner units for such class outstanding during the period. Diluted earnings per limited partner unit reflects, where applicable, the potential dilution that could occur if securities or other agreements to issue additional units of a limited partner class, such as restricted unit awards, were exercised, settled or converted into such units. At March 31, 2012, the dilutive effect of our restricted stock awards was immaterial.

7. RELATED PARTY TRANSACTIONS

Direct employee expenses

We do not directly employ any persons to manage or operate our business. These functions are performed by employees of SemGroup. SemGroup charged us $2.9 million and $2.5 million during the three months ended March 31, 2012 and 2011, respectively, for direct employee costs. These expenses were recorded to operating expenses and general and administrative expenses in our consolidated statements of income.

Allocated expenses

SemGroup incurs expenses to provide certain indirect corporate general and administrative services to its subsidiaries. Such expenses include employee compensation costs, professional fees and rental fees for office space, among other expenses. SemGroup charged us $1.2 million and $1.3 million during the three months ended March 31, 2012 and 2011, respectively, for such allocated costs. These expenses were recorded to general and administrative expenses in our consolidated statements of income.

SemGroup credit facilities

SemGroup was a borrower under various credit agreements during the periods included in these financial statements. Prior to our initial public offering, SemCrude, along with other subsidiaries of SemGroup, served as subsidiary guarantors under certain of these agreements. SemGroup did not allocate this debt to its subsidiaries, and our statements of income do not include any allocated interest expense, prior to our initial public offering. SemGroup did not charge us interest expense on intercompany payables.

Prior to our initial public offering, we utilized letters of credit under SemGroup’s credit facilities. Our statements of income include direct charges from SemGroup for letter of credit usage, which is reported within interest expense.

Subsequent to our initial public offering, which was completed on December 14, 2011, our assets no longer serve as collateral under SemGroup’s credit agreement.

Predecessor cash management

Prior to our initial public offering, we participated in SemGroup’s cash management program. Under this program, cash we received from customers was transferred to SemGroup on a regular basis; when we remitted payments to suppliers, SemGroup transferred cash to us to cover the payments. Such cash transfers were recorded to intercompany accounts.

NGL Energy

SemGroup acquired certain ownership interests in NGL Energy Partners LP (“NGL Energy”) and its general partner on November 1, 2011. During the three months ended March 31, 2012, we made purchases of natural gasoline and condensate from NGL Energy in the amount of $14.4 million.

SemStream

We purchased condensate from SemStream, L.P. (“SemStream”), which is also a wholly-owned subsidiary of SemGroup. Certain of these purchases were fixed price forward purchases, which we recorded at fair value at each balance sheet date, with the unrealized gains being recorded to revenue. Our transactions with SemStream consisted of the following (amounts in thousands):

	Three Months Ended March  31, 2012		Three Months Ended March 31, 2011
Sales	$	—	$	831
Purchases	$	—	$	12,917

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited condensed consolidated interim financial statements and the notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q, and our Annual Report on Form 10-K for the year ended December 31, 2011, filed with the SEC.

Overview of Business

We are a growth-oriented Delaware limited partnership formed in 2011 by SemGroup to own, operate, develop and acquire a diversified portfolio of midstream energy assets. We are engaged in the business of crude oil gathering, transportation, storage and marketing in Colorado, Kansas, Montana, North Dakota, Oklahoma and Texas. We serve areas that are experiencing strong production growth and drilling activity through our exposure to the Bakken Shale in North Dakota and Montana, the DJ Basin and the Niobrara Shale in the Rocky Mountain region, and the Granite Wash and the Mississippian oil trend in the Mid-Continent region. The majority of our assets are strategically located in, or connected to, the Cushing, Oklahoma crude oil marketing hub. Cushing is the designated point of delivery specified in all NYMEX crude oil futures contracts and is one of the largest crude oil marketing hubs in the United States. We believe that our connectivity in Cushing and our numerous interconnections with third-party pipelines, refineries and storage terminals provide our customers with the flexibility to access multiple points for the receipt and delivery of crude oil.

We own and operate all of our assets, which include:

• 7.0 million barrels of crude oil storage capacity in Cushing;

• a 640-mile crude oil gathering and transportation pipeline system with over 560,000 barrels of associated storage capacity in Kansas and northern Oklahoma that is connected to several third-party pipelines and refineries and our storage terminal in Cushing, and an additional 100,000 barrels of storage currently under construction;

• a crude oil gathering, storage, transportation and marketing business in the Bakken Shale in North Dakota and Montana in which we marketed an average of 8,200 barrels of crude oil per day for the three months ended March 31, 2012; and

• a modern, ten-lane crude oil truck unloading facility with 220,000 barrels of associated storage capacity in Platteville, Colorado which connects to the origination point of SemGroup’s White Cliffs Pipeline, with an additional six truck unloading lanes and 10,000 barrels of storage expected to be completed by the end of 2012.

For the three months ended March 31, 2012, approximately 70% of our adjusted gross margin was generated from fee-based services or fixed-margin transactions. For a definition of adjusted gross margin and a reconciliation of adjusted gross margin to operating income, its most directly comparable financial measure calculated and presented in accordance with generally accepted accounting principles (“GAAP”), please see “Non-GAAP Financial Measures”.

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, including adjusted gross margin, operating expenses and adjusted EBITDA, and operating data, including contracted storage capacity and transportation, marketing and unloading volumes.

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 crude oil, and our fixed-margin and marketing operations, which do. In particular, adjusted gross margin provides a way to compare the actual transportation fee received under fixed-fee contracts with the effective transportation fee realized through a fixed-margin transaction. 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 cost of products sold. See “Non-GAAP Financial Measures”.

Page 16

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 any non-cash adjustments to reconcile net income (loss) to net cash provided by (used in) operating activities. We use adjusted EBITDA as a supplemental performance and liquidity 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;

• the ability of our assets to generate sufficient cash flow to make distributions to our partners;

• our ability to incur and service debt and fund capital expenditures; and

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

Contracted Storage Capacity and Transportation, Marketing and Unloading Volumes

In our Cushing storage operations, we charge our customers a fee for storage capacity provided, regardless of actual usage. On our Kansas and Oklahoma system, we provide transportation services on a fee basis or pursuant to fixed-margin transactions, but in either case, the adjusted gross margin we generate is dependent on the volume of crude oil transported (if on a fee basis) or purchased and sold (if pursuant to a fixed-margin transaction). We refer to these volumes, in the aggregate, as transportation volumes. Similarly, on our Kansas and Oklahoma system, and through our Bakken Shale operations, we conduct marketing activities involving the purchase and sale of crude oil or related derivative contracts. We refer to the crude oil volumes purchased and sold in our marketing operations as marketing volumes. Finally, at our Platteville truck unloading facility, we charge our customers a fee based on the volumes unloaded. We refer to these as unloading volumes.

How We Generate Adjusted Gross Margin

We generate adjusted gross margin by providing fee-based services, by entering into fixed-margin transactions and through marketing activities. Revenues from our fee-based services are included in service revenue, and revenues from our fixed-margin and marketing activities are included in product revenue.

The following table shows the adjusted gross margin generated by our storage, transportation and marketing activities for the three months ended March 31, 2012 (in thousands):

	Storage		Transportation		Marketing Activities			Other (1)		Total

(1) This category includes fee-based services such as unloading and ancillary storage terminal services.

Fee-Based Services

We charge a capacity or volume-based fee for the unloading, transportation and storage of crude oil and related ancillary services. Our fee-based services include substantially all of our operations in Cushing, Oklahoma and Platteville, Colorado and a portion of the transportation services we provide on our Kansas and Oklahoma pipeline system. Some of our fee-based contracts are take-or-pay contracts whereby the customer is required to pay us a fixed minimum monthly fee regardless of usage. For the three months ended March 31, 2012 and 2011, approximately 53% and 59%, respectively, of our adjusted gross margin was generated by providing fee-based services to customers.

Fixed-Margin Transactions

We purchase crude oil from a producer or supplier at a designated receipt point at an index price less a transportation fee, and simultaneously sell 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 we generate on our Kansas and Oklahoma pipeline system and through our Bakken Shale operations. For the three months ended March 31, 2012 and 2011, approximately 17% and 15%, respectively, of our adjusted gross margin was generated through fixed-margin transactions.

Marketing Activities

We conduct marketing activities by purchasing crude oil for our own account from producers, aggregators and traders and selling crude oil to traders and refiners. Our marketing activities account for a portion of the adjusted gross margin we generate on our Kansas and Oklahoma pipeline system and through our Bakken Shale operations. For the three months ended March 31, 2012 and 2011, approximately 30% and 26%, respectively, of our adjusted gross margin 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. 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 entering into futures and swaps contracts on the NYMEX or over-the-counter markets.

Selected Consolidated Financial and Operating Data

The following table provides selected historical condensed consolidated financial operating data as of and for the periods shown. The statements of income data and cash flow for the three months ended March 31, 2012 and 2011 have been derived from our unaudited financial statements for those dates and periods. The selected financial data provided below should be read in conjunction with our condensed consolidated financial statements and related notes included in this Form 10-Q.

The following table presents the non-GAAP financial measures of adjusted gross margin and adjusted EBITDA, which we use in our business and view as important supplemental measures of our performance and, in the case of adjusted EBITDA, our liquidity. Adjusted gross margin and adjusted EBITDA are not calculated or presented in accordance with GAAP.

Non-GAAP Financial Measures

We define adjusted gross margin as total revenues minus cost of products sold and unrealized gain (loss) on derivatives. We define adjusted EBITDA as net income (loss) before interest expense, income tax expense (benefit), depreciation and amortization and any non-cash adjustments to reconcile net income (loss) to net cash provided by (used in) operating activities. 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 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) and cash provided by (used in) operating activities are the GAAP measures 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. These non-GAAP financial measures have important limitations as analytical tools because they exclude some, but not all, items that affect the most directly comparable GAAP financial measures. You should not consider adjusted gross margin and adjusted EBITDA in isolation or as substitutes 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 limitation of adjusted gross margin and adjusted EBITDA as analytical tools by reviewing the comparable GAAP measures, understanding the differences between adjusted gross margin and adjusted EBITDA, on the one hand, and operating income (loss), net income (loss) and net cash provided by (used in) operating activities, 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.

ASC 845-10-15, “Nonmonetary Transactions,”requires certain transactions – those where inventory is purchased from a customer then resold to the same customer – 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. However, changes in the level of such purchase and sale activity between periods can have an effect on the comparison between those periods.

Three months ended March 31, 2012 vs. three months ended March 31, 2011

Revenue

Revenue increased in the three months ended March 31, 2012 to $180 million from $84 million for the three months ended March 31, 2011, as shown in the following table:

Page 21

	Three Months Ended March 31, 2012			Three Months Ended March 31, 2011
	(in thousands)
Gross product revenue	$	501,478		$	210,376
Nonmonetary transaction adjustment		(331,946	)		(137,708	)
Unrealized gain (loss) on derivatives, net		(146	)		1,589

Service revenue		10,334			9,423
Other		(5	)		111
Total revenue	$	179,715		$	83,791

Gross product revenue increased in the three months ended March 31, 2012 to $501 million from $210 million in three months ended March 2011. The increase was primarily due to volume of 5.0 million barrels sold for the three months ended March 31, 2012, at an average sales price of $101 per barrel, compared to 2.3 million barrels sold during the three months ended March 31, 2011, at an average sales price of $91 per barrel.

Gross product revenue was reduced by $332 million and $138 million during the three months ended March 31, 2012 and March 31, 2011, respectively, in accordance with ASC 845-10-15.

Service revenue increased to $10 million in the three months ended March 31, 2012 from $9 million in the three months ended March 31, 2011, due to the completion of additional storage capacity in Cushing.

Costs of Products Sold

Costs of products sold increased in the three months ended March 31, 2012 to $161 million from $66 million in the three months ended March 31, 2011. Costs of products sold reflected reductions of $332 million and $138 million in the three months ended March 31, 2012 and March 31, 2011, respectively, in accordance with ASC 845-10-15. Costs of products sold increased due to the increase in the volume of barrels sold per month described above, combined with an increase in the average per barrel cost of crude oil to $98 for the three months ended March 31, 2012 from $88 for the three months ended March 31, 2011.

Adjusted Gross Margin

We define adjusted gross margin as total revenues minus costs of products sold and unrealized gain (loss) on derivatives. (See “Non-GAAP Financial Measures”.) Adjusted gross margin increased in the three months ended March 31, 2012 to $19 million from $16 million in the three months ended March 31, 2011, due to:

• an increase in marketing volume (which is a subset of the total volume sold as shown above) of approximately 1.1 million barrels, partially offset by a lower spread between the purchase and sale price for volumes of crude oil sold, as the excess of our average sales price per barrel over our average purchase cost per barrel decreased to approximately $3 from approximately $5;

• an increase in unloading volumes from our Platteville operations of approximately 1.2 million barrels; and

• an increase from our storage operations of approximately 4.5 million barrels in contracted storage capacity to 6.2 million barrels.

General and administrative

General and administrative expense increased in the three months ended March 31, 2012 to $2.7 million from $2.4 million in the three months ended March 31, 2011. This increase is due to incremental outside professional fees related to a new structure as a publicly traded partnership.

Depreciation

Depreciation and amortization expense increased in the three months ended March 31, 2012 to $3.0 million from $2.7 million in the three months ended March 31, 2011. This increase results directly from an increase in depreciable assets.

Page 22

Liquidity and Capital Resources

Our sources of liquidity may include:

• cash generated from operations;

• borrowings under our credit facility; and

• issuances of debt and equity securities.

We believe that the cash generated from these sources will be sufficient to allow us to distribute the minimum quarterly distribution on all of our outstanding common, subordinated and general partner units and meet our requirements for working capital and capital expenditures for the foreseeable future.

Working Capital

Working capital is the amount by which current assets exceed current liabilities and is a measure of our ability to pay our liabilities as they become due. Our working capital was $32 million and $26 million at March 31, 2012 and December 31, 2011, respectively.

Cash Flows

Operating Activities. We experienced operating cash outflows of $0.2 million during the three months ended March 31, 2012. Net income of $8 million included $3 million of non-cash expenses, comprised primarily of depreciation and amortization. The primary changes to working capital were an increase to accounts receivable of $84 million and an increase in receivables from affiliates of $4 million. These changes were offset by an increase in accounts payable of $69 million, a decrease in inventory of $5 million and an increase in payables to affiliates of $2 million.

We experienced operating cash inflows of $25 million during the three months ended March 31, 2011. Net income of $8 million included $2 million of non-cash expenses, comprised primarily of depreciation and amortization, and we used $15 million of cash for working capital. The use of cash for working capital included a $24 million increase in accounts payable, which was partially offset by a $4 million increase in accounts receivable and a $5 million increase in inventories.

Investing Activities. Our cash outflows from investing activities related primarily to capital expenditures of $3 million for the three months ended March 31, 2012 and $2 million for the three months ended March 31, 2011. These capital expenditures related primarily to the construction of storage tanks at our terminal in Cushing, Oklahoma.

Financing Activities. Our cash outflow from financing activities for the three months ended March 31, 2012 and 2011 consisted primarily of distributions to partners in the amount of $1.1 million and $24.2 million, respectively.

Capital Requirements

The midstream energy business can be capital intensive, requiring significant investment for the maintenance of existing assets or acquisition or development of new systems and facilities. We categorize our capital expenditures as either:

• maintenance capital expenditures, which are cash expenditures (including expenditures for the addition or improvement to, or the replacement of, our capital assets or for the acquisition of existing, or the construction or development of new, capital assets) made to maintain our long-term operating income or operating capacity; or

• expansion capital expenditures, which are cash expenditures incurred for acquisitions or capital improvements that we expect will increase our operating income or operating capacity over the long term.

We have budgeted $37.4 million in capital expenditures for the year ending December 31, 2012, of which $33.7 million represents expansion capital expenditures, which are related to the construction of 1.95 million barrels of storage capacity at our Cushing terminal, a truck unloading bay expansion at Platteville and other strategic growth projects, and $3.7 million represents maintenance capital expenditures, of which $0.9 million is related to truck replacements. The remaining $2.8 million is related primarily to increased pipeline integrity management expenses to comply with new regulations. We spent $3 million in capital expenditures during the three months ended March 31, 2012.

Page 23

In addition to our budgeted capital program, we anticipate that we will continue to make significant expansion capital expenditures in the future. Consequently, our ability to develop and maintain sources of funds to meet our capital requirements is critical to our ability to meet our growth objectives. We expect that our future expansion capital expenditures will be funded by borrowings under our credit facility and the issuance of debt and equity securities.

Distributions

The cash distribution for the fourth quarter of 2011 was $0.0670 per unit. This prorated amount corresponds to the minimum quarterly cash distribution of $0.3625 per unit, or $1.45 per unit on an annualized basis. The proration period began on December 15, 2011, immediately after the closing date of our initial public offering, and continued through December 31, 2011. The distribution was paid on February 13, 2012 to all unitholders of record as of February 3, 2012.

The cash distribution for the first quarter of 2012 is $0.3725 per unit, or $1.49 per unit on an annualized basis. This represents a 2.8% increase over the prior quarter on an annualized basis and marks the first increase in the distribution to our limited partner unitholders. The distribution will be paid on May 15, 2012 to all unitholders of record as of May 7, 2012.

Revolving Credit Facility

On November 10, 2011, we 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 $75.0 million of letters of credit, to finance capital expenditures and other permitted payments and for other lawful corporate purposes and will allow us 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 March 31, 2012, we had no outstanding borrowings on the revolving credit facility and had $29.8 million outstanding in letters of credit. Our obligations under the credit facility are secured by a first priority lien on substantially all of our material assets. The credit facility matures on December 14, 2016. Borrowings under the credit facility bear interest at either an alternative base rate or an adjusted Eurodollar rate, in each case plus an applicable margin. The applicable margin varies based upon our leverage ratio, as defined in the credit facility. At March 31, 2012, had there been any borrowings under the revolving credit, the interest rate applicable to alternate base rate borrowings was 4.50% and the interest rate applicable to Eurodollar rate borrowings was 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, 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 March 31, 2012, we had $9 million of Secured Bilateral Letters of Credit outstanding and the interest rate in effect was 1.75%.

We recorded $0.5 million of interest expense during the three months ended March 31, 2012 related to this facility, including amortization of debt issuance costs.

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

• permit the ratio of our consolidated EBITDA to our 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;

• permit the ratio of our consolidated net debt to our consolidated EBITDA at the end of any fiscal quarter, for the immediately preceding four quarter period, to be greater than 4.50 to 1.00 (or 5.00 to 1.00 during a temporary period from the date of funding of the purchase price of certain acquisitions (as described in the credit facility) until the last day of the third fiscal quarter following such acquisitions);

• incur additional debt, subject to customary carve outs for certain permitted additional debt, incur certain liens on assets, subject to customary carve outs for certain permitted liens, or enter into certain sale and leaseback transactions;

• make investments in or make loans or advances to persons that are not Restricted Subsidiaries, subject to customary carve out for certain permitted investments, loans and advances;

Page 24

• make certain cash distributions, provided that we may make distributions of available cash so long as no default under the credit agreement then exists or would result therefrom;

• dispose of assets in excess of an annual threshold amount;

• make certain amendments, modifications or supplements to organization documents, our Comprehensive Risk Management Policy, other material indebtedness documents and material contracts or enter into certain restrictive agreements or make certain payments on subordinated indebtedness;

• engage in business activities other than our business as described herein, incidental or related thereto or a reasonable extension of the foregoing;

• enter into hedging agreements, subject to a customary carve out for agreements entered into in the ordinary course of business for non-speculative purposes;

• make changes to our fiscal year or other significant changes to our accounting treatment and reporting practices;

• engage in certain mergers or consolidations and transfers of assets; and

• enter into transactions with affiliates unless the terms are not less favorable, taken as a whole, than would be obtained in an arms-length transaction, subject to customary exceptions.

As of March 31, 2012, we were in compliance with our covenants under our credit facility.

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 our general partner. 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 us and the collateral as may be available to the lenders under the credit facility and other loan documents.

Credit Risk

We are subject to risks of loss resulting from nonpayment or nonperformance by our customers. We examine the creditworthiness of third party customers to whom we extend credit and manage our exposure to credit risk through credit analysis, credit approval, credit limits and monitoring procedures, and for certain transactions, we may request letters of credit, prepayments or guarantees.

Customer Concentration

4K Fuel Supply, LLC, Vitol S.A, Shell Trading (US) Company, and BP Canada Energy Marketing Corp., each accounted for more than 10% of our total revenue for the three months ended March 31, 2012, at approximately 20%, 17%, 13% and 12%, respectively. Although we have contracts with customers of varying duration, if one or more of our major customers were to default on their contract or if we were unable to renew our contract with one or more of these customers on favorable terms, we might not be able to replace any of these customers in a timely fashion, on favorable terms or at all. In any of these situations, our revenues and our ability to make cash distributions to our unitholders may be adversely affected. We expect our exposure to risk of non-payment or non-performance to continue as long as we remain substantially dependent on a relatively small number of customers for a substantial portion of our adjusted gross margin.

Page 25

Purchases and Sales Commitments

We routinely enter into agreements to purchase and sell petroleum products at specified future dates. We establish a margin for these purchases by entering into various types of physical and financial sales and exchange transactions through which we seek to maintain a position that is substantially balanced between purchases, on the one hand, and sales and future delivery obligations, on the other. 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 March 31, 2012, such commitments included the following (in thousands):

	Volume (barrels)		Value
Fixed price purchases		53	$	4,975
Fixed price sales		128	$	13,382
Floating price purchases		31,585	$	3,240,715
Floating price sales		31,846	$	3,330,409

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.

Letters of Credit

In connection with our purchasing activities, we provide certain suppliers and transporters with irrevocable standby and performance letters of credit to secure our obligation for the purchase of crude oil. Our liabilities with respect to these purchase obligations are recorded as accounts payable on our balance sheet in the month the crude oil is purchased. Generally, these letters of credit are issued for 50- to 70-day periods (with a maximum of a 364-day period) and are terminated upon completion of each transaction. At March 31, 2011 and December 31, 2011, we had outstanding letters of credit of approximately $29.8 million and $39.6 million, respectively.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3. 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 and interest 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 crude oil prices and interest rates. We have in the past used, and expect that in the future we will continue to use, 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.

Commodity Price Risk

Commodity prices have historically been volatile and cyclical. For example, NYMEX West Texas Intermediate benchmark prices have ranged from an all-time high of over $145 per barrel (June/July 2008) to a low of approximately $10 per barrel (March 1986) over the last 25 years. The table below outlines the range of NYMEX prompt month daily settle prices for crude oil for the three months ended March 31, 2012 and 2011 and for the years ended December 31, 2011 and 2010.

	Light Sweet Crude Oil Futures ($ per Barrel)			Light Sweet Crude Oil Futures ($ per Barrel)
Three Months Ended March 31, 2012			Three Months Ended March 31, 2011
High	$	109.77	High	$	106.72
Low	$	96.36	Low	$	84.32
High/Low Differential	$	13.41	High/Low Differential	$	22.40
Year Ended December 31, 2011			Year Ended December 31, 2010
High	$	113.93	High	$	91.51
Low	$	75.67	Low	$	68.01
High/Low Differential	$	38.26	High/Low Differential	$	23.50

Revenue from our asset-based activities is dependent on throughput volume, tariff rates, the level of fees generated from our pipeline systems, capacity contracted to third parties, capacity that we use for our own operational or marketing activities and the level of other fees generated at our storage facilities. Profit from our marketing activities is dependent on our ability to sell crude oil 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 crude oil marketing activities are generally not directly affected by the absolute level of crude oil prices, but are affected by overall levels of supply and demand for crude oil and relative fluctuations in marked-related indices.

Based on our open derivative contracts at March 31, 2012, a 5% increase in the applicable market price or prices for each derivative contract would result in a less than $0.1 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 $0.1 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.

Page 27

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 have exposure to changes in interest rates under our new credit facility. The credit markets have recently experienced historical lows in interest rates. If the overall economy strengthens, it is likely that monetary policy will tighten, resulting in higher interest rates to counter possible inflation. Interest rates on our credit facility and future debt offerings could be higher than current levels, causing our financing costs to increase accordingly.

Prior to our initial public offering, substantially all of our interest expense was incurred at fixed rates. As a result, an increase or decrease in interest rates would have had no material impact on our interest expense for the period during 2011 prior to our initial public offering. We recorded interest expense related to our credit facility of $0.5 million during the three months ended March 31, 2012. An increase in interest rates of 1% would have increased our interest expense by $77.2 thousand during the three months ended March 31, 2012.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Chief Executive Officer and Chief Financial Officer of our general partner have concluded that the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are effective as of March 31, 2012. This conclusion is based on an evaluation conducted under the supervision and participation of the Chief Executive Officer and Chief Financial Officer of our general partner along with our management. Disclosure controls and procedures are those controls and procedures designed to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer of our general partner, as appropriate to allow timely decisions regarding required disclosure.

Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2012 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.
