Item 3.02 Unregistered Sales of Equity Securities

On November 2, 2012, PJC Capital, LLC (“PJC”), a Delaware limited liability company, exercised its rights under a Warrant to Purchase Units of Advanced BioEnergy, LLC dated October 7, 2009 (“Warrant”). The Warrant entitled PJC to purchase 532,671 Units of the Advanced BioEnergy (“the Company”) at an exercise price of $1.50 per Unit. The Company has received proceeds of $799,006 from the exercise of the Warrant, and is issuing 532,671 Units of the Company to PJC. After issuance of the Units pursuant to the Warrant, the Company will have 25,246,851 Units outstanding.

The issuance of the Units upon exercise of the Warrant is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Act”), in accordance with Section 4(2) of the Act and Regulation D under the Act. We have reasonable grounds to believe that PJC is an “accredited investor” within the meaning of Rule 501 of Regulation D. The Warrant was originally issued to PJC in October 2009 in connection with the restructuring and subsequent repayment of indebtedness of the Company to PJC.
