Item 2.01 Completion of Acquisition or Disposition of Assets.

On February 26, 2010, Blackhawk Biofuels, LLC completed the closing of the merger (the “Merger”) with REG Danville, LLC, a Delaware limited liability company (“Merger Sub”) and a wholly owned subsidiary of REG Newco, Inc., a Delaware corporation (“Newco”), pursuant to the Second Amended and Restated Agreement and Plan of Merger (the “Merger Agreement”), executed November 21, 2009, by and among Blackhawk, Newco, Merger Sub and Renewable Energy Group, Inc., a Delaware corporation (“REG”). The Merger became effective by the filing of a Certificate of Merger with the Secretary of State of Delaware on February 26, 2010.

In accordance with the Merger Agreement, in the Merger each outstanding Series A Unit of Blackhawk (other than such units held by REG or any affiliate of REG) was converted into 0.4479 shares of Newco Common Stock (rounded up for any fractional shares) and 0.0088 shares of Newco Series A Preferred Stock (rounded up for any fractional shares). Series A Units of Blackhawk held by REG or any affiliate of REG remained outstanding following the Merger. Each outstanding warrant for the purchase of Series A Units of Blackhawk was assumed by Newco for the purchase of shares of Newco Common Stock, with the number of shares and exercise price per share adjusted appropriately based on the 0.4479 shares exchange ratio.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement filed as Exhibit 2.1 to Blackhawk’s Current Report on Form 8-K filed on November 25, 2009, which is incorporated into this Report by reference as Exhibit 10.1 hereto, and which is incorporated into this discussion by reference.

Upon the effectiveness of the Merger on February 26, 2010, a change in control of Blackhawk occurred. Pursuant to the terms of the Merger Agreement, Merger Sub was merged with and into Blackhawk, with Blackhawk continuing as the surviving company, each outstanding Series A Unit of Blackhawk (other than such units held by REG or any affiliate of REG) was converted into the right to receive shares of Common Stock and Series A Preferred Stock of Newco and outstanding warrants to purchase Series A Units of Blackhawk were assumed by Newco and became warrants for the purchase of shares of Common Stock of Newco. Series A Units of Blackhawk held by REG or any affiliate of REG remained outstanding following the Merger. As a result of the Merger, Blackhawk became a subsidiary of Newco.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
