Explanation of Responses:

( 1 )As previously disclosed in Blueknight Energy Partners, L.P.'s (the "Issuer") Form 10-K for the fiscal year ended December 31, 2010 (the "2010 Form 10-K"), pursuant to the Purchase, Sale & Co-Investment Agreement by and between CB-Blueknight, LLC ("Charlesbank Holding") and Blueknight Energy Holding, Inc. ("Vitol Holding") dated as of October 21, 2010, on November 12, 2010 Vitol Holding sold 6,285,252 Subordinated Units (the "Subordinated Units") of the Issuer to Charlesbank Holding. ( 2 )As of November 12, 2010 and as of September 14, 2011, the Subordinated Units had no expiration date and were convertible on a one-for-one basis into Common Units representing limited partner interests of the Issuer ("Common Units") at the end of the subordination period, as set forth in the Issuer's Third Amended and Restated Agreement of Limited Partnership, dated as of October 25, 2010, filed with the Securities and Exchange Commission as Exhibit 3.1 to the Issuer's Current Report on Form 8-K filed with the Securities and Exchange Commission on October 25, 2010 (the "Form 8-K"). ( 3 )As previously disclosed in the Issuer's Current Report on Form 8-K filed with the Securities and Exchange Commission on September 14, 2011, the outstanding Subordinated Units were cancelled on September 14, 2011 pursuant to the adoption of the Fourth Amended and Restated Agreement of Limited Partnership of the Issuer. ( 4 )As previously disclosed in the Issuer's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2011 (the "2011 Third Quarter 10-Q"), on November 9, 2011, the Issuer repurchased 1,612,747 of the Series A Preferred Units representing limited partner interests of the Issuer (the "Preferred Units") for an aggregate of $10,608,194.65 (being $6.50 per Preferred Unit and $0.078 per Preferred Unit as a pro-rata distribution amount) from each of Charlesbank Holding and Vitol Holding, after which each of Charlesbank Holding and Vitol Holding retained 9,156,484 Preferred Units. ( 5 )The Preferred Units have no expiration date and are convertible at any time, in whole or in part, on a one-for-one basis into Common Units representing limited partner interests of the Issuer at the holder's election as set forth in the Fourth Amended and Restated Agreement of Limited Partnership of the Issuer, dated September 14, 2011 and filed with the Securities and Exchange Commission as Exhibit 3.1 to the Issuer's Current Report on Form 8-K filed on September 14, 2011. ( 6 )As previously disclosed in the 2011 Third Quarter 10-Q, on November 9, 2011, the Issuer redeemed the Convertible Debenture for a price equal to its face value of $25,000,000, plus the accrued and unpaid interest thereon. If not otherwise redeemed, the Convertible Debenture was to mature on December 31, 2011 and, on such date, all outstanding principal and any accrued and unpaid interest were to automatically convert into Preferred Units. The terms of the Convertible Debenture are described more fully in the Form 8-K. ( 7 )As of each transaction date reported herein, these securities were owned directly by Charlesbank Holding. This form is jointly filed by Charlesbank Holding, Charlesbank Equity Fund VII, Limited Partnership ("Fund VII"), Charlesbank Equity Fund VII GP, Limited Partnership ("Equity VII GP") and Charlesbank Capital Partners, LLC ("Charlesbank"). Fund VII is the manager of Charlesbank Holding and may be deemed to indirectly beneficially own the securities of the Issuer held by Charlesbank Holding but disclaims beneficial ownership except to the extent of its pecuniary interest therein. ( 8 )Equity VII GP is the general partner of Fund VII and may be deemed to indirectly beneficially own the securities of the Issuer held by Fund VII but disclaims beneficial ownership except to the extent of its pecuniary interest therein. Charlesbank is the general partner of Equity VII GP and therefore may be deemed to indirectly beneficially own the securities of the Issuer held by Equity VII GP, but disclaims beneficial ownership except to the extent of its pecuniary interest therein. Charlesbank serves as the investment advisor to Fund VII and the investment adviser or general partner to certain other affiliated funds that have a pecuniary interest in the securities of the Issuer owned by Charlesbank Holding but do not control Charlesbank Holding.

Remarks: Charlesbank Holding owns 50% of the equity interests in Blueknight GP Holding, LLC ("GP Holding"), which owns 100% of the outstanding equity interests in Blueknight Energy Partners G.P., L.L.C., the general partner of the Issuer (the "GP"). Pursuant to the Amended and Restated Limited Liability Company Agreement of GP Holding, dated as of November 12, 2010, Charlesbank Holding has the power to designate two directors to the GP's board of directors (the "Board"). Messrs. Michael R. Eisenson and Jon M. Biotti, both of whom are affiliated with Charlesbank Holding, were appointed by Charlesbank Holding to the Board on November 12, 2010 as more fully described in the Issuer's Current Report on Form 8-K filed with the Securities and Exchange Commission on November 16, 2010. Therefore, Charlesbank Holding may be deemed a director by deputization.

Reminder: Report on a separ ate line for each class of securities beneficially owned directly or indirectly.
