Item 1.01 Entry into a Material Definitive Agreement

     On August 30, 2010, Calumet Shreveport Fuels, LLC (“Calumet Shreveport Fuels”), a wholly-owned subsidiary of Calumet Specialty Products Partners, L.P. (the “Company”), entered into Amendment No. 4 to Crude Oil Supply Agreement (the “Shreveport Amendment”) with Legacy Resources Co., L.P. (“Legacy”), a related party. The Shreveport Amendment, effective as of September 1, 2010, modifies the market-based pricing mechanism established in the Crude Oil Supply Agreement, effective as of September 1, 2009, by and between Calumet Shreveport Fuels and Legacy, under which Legacy supplies the Company’s Shreveport refinery with a portion of the refinery’s crude oil requirements on a just-in-time basis.

     On August 30, 2010, Calumet Lubricants Co., L.P. (“Calumet Lubricants”), a wholly-owned subsidiary of the Company, entered into Amendment No. 4 to Crude Oil Supply Agreement (the “Princeton Amendment”) with Legacy. The Princeton Amendment, effective as of September 1, 2010, modifies the market-based pricing mechanism established in the Crude Oil Supply Agreement, effective as of April 30, 2008, by and between Calumet Lubricants and Legacy, under which Legacy supplies the Company’s Princeton refinery with all of the refinery’s crude oil requirements on a just-in-time basis.

     Because Legacy is owned in part by The Heritage Group, an affiliate of the Company’s general partner, the Company’s chief executive officer and president, F. William Grube, and the Company’s executive vice president and chief operating officer, Jennifer G. Straumins, the terms of the Shreveport Amendment and the Princeton Amendment were reviewed by the Company’s conflicts committee, which consists entirely of independent directors. The conflicts committee approved the Shreveport Amendment and the Princeton Amendment after determining that their terms are fair and reasonable to the Company.

     The foregoing description is qualified in its entirety by reference to the Shreveport Amendment and the Princeton Amendment, copies of which are attached hereto as Exhibit 10.24 and Exhibit 10.25, respectively.
