Blueknight Energy Partners

SemGroup Energy Partners, L.P. ("SGLP") (Pink Sheets: SGLP) today announced a net loss of $2.9 million, or $0.08 per basic and diluted common unit, on total revenues of $40.0 million, for the three months ended September 30, 2009. For the nine months ended September 30, 2009, SGLP announced a net loss of $8.0 million, or $0.23 per basic and diluted common unit, on total revenues of $119.7 million.

These results compare to a net loss of $11.9 million and net income of $19.5 million on revenues of $53.8 million and $149.3 million for the three and nine months ended September 30, 2008, respectively.

SGLP generated $14.1 million and $45.0 million in earnings before interest, taxes, depreciation and amortization, or EBITDA, for the three and nine months ended September 30, 2009, respectively. This EBITDA is inclusive of certain expenses totaling $3.0 million and $10.1 million for the three and nine months ended September 30, 2009, respectively, related primarily to incremental professional and legal expenses associated with the bankruptcy of SemGroup, L.P. (the "Private Company") and the reconstruction of SGLP's business following the Private Company's bankruptcy. These expenses are expected to be nonrecurring. EBITDA is a non-generally accepted accounting principles (or "non-GAAP") financial measure that is explained and reconciled to net income (loss) later in this press release.

Net income (loss) and EBITDA continue to be impacted by decreased revenues in the Crude Oil Gathering and Transportation and Asphalt Services segments. Revenues in the Crude Oil Gathering and Transportation segment have been significantly impacted by the Private Company's bankruptcy filing which has led to decreased volumes being transported. Historically, the Private Company was a purchaser of crude oil and utilized SGLP's gathering and transportation assets to deliver its crude oil to market. As SGLP is not in the business of purchasing crude oil, the utilization of SGLP's crude oil gathering and transportation assets is now dependent on third party purchasers of crude oil, some of whom own alternative gathering and transportation assets.

Further, revenues in the Asphalt Services segment were impacted by the Private Company's rejection of the Terminalling Agreement effective March 31, 2009, and the timing of SGLP's entering into new leases and storage agreements with third party customers in the middle of the second quarter of 2009.

The negative revenue impacts were partially offset by comparable year-over-year revenues from the Crude Oil Terminalling and Storage segment which reflect continued strong demand for crude oil storage.

General and administrative expenses decreased $20.1 million and $10.3 million for the three and nine months ended September 30, 2009, respectively, as compared to similar periods in 2008. General and administrative expenses for the three and nine months ended September 30, 2008 include an incremental $18.0 million of non-cash compensation expense due to the vesting of all outstanding awards under SGLP's Long Term Incentive Plan resulting from the change of control of SGLP's general partner that occurred in July of 2008. This decrease was partially offset in the three months ended September 30, 2009 by increased costs related to legal and financial advisers as well as other related costs incurred in connection with events related to the Private Company's bankruptcy, the securities litigation and governmental investigations, and our efforts to enter into storage contracts with third party customers and pursue other strategic opportunities.

Interest expense increased by $0.2 million and $19.8 million for the three and nine months ended September 30, 2009, respectively compared to similar periods in 2008. The increase was primarily due to both an increase in average borrowings outstanding as a result of our financing of the purchase of pipeline and storage assets from the Private Company in early 2008 and higher interest rates under our amended credit facility.

On October 8, 2009, SGLP announced that Vitol, Inc. entered into an agreement to purchase the general partner of SGLP. Vitol Inc. is the principal U.S. subsidiary of the Vitol Group. Vitol is engaged in the global physical supply and distribution of crude oil, petroleum products, coal, natural gas, and other commodities. Vitol was founded in 1966, and is headquartered in the Netherlands. Vitol moves over 5 million barrels of crude oil and petroleum products every day throughout the world, charters more than 3,000 ships annually and had annual revenues of $191 billion in 2008.

Kevin Foxx, President and Chief Executive Officer of SGLP's general partner, stated, "Third quarter results and the pending change of control of our general partner are anticipated to further stabilize our transportation and storage business. We expect the Vitol transaction to close in the near future after consent is received from our lenders and look forward to the new era with Vitol as the owner of our general partner. Lastly, we are pleased to announce that we are changing our name to Blueknight Energy Partners, L.P. and expect the change to become effective on December 1, 2009. We are extremely excited to continue our business as Blueknight Energy Partners and expanding our presence under a new flag and leadership. We will update information regarding our ticker symbol as soon as a new one has been assigned to us."
