Section 2 – Financial Information

Item 2.01. Completion of Acquisition or Disposition of Assets.

On August 30, 2010, Exelon Generation Company, LLC (Generation), a wholly owned subsidiary of Exelon Corporation (Exelon), and Deere & Company (Deere) entered into a Purchase Agreement (the Purchase Agreement), under which Exelon Generation agreed to purchase all of the membership interests of John Deere Renewables, LLC (JDR), an owner and operator of 735 megawatts of operating wind electric generating facilities. The acquisition also includes all projects under development by JDR, including three projects totaling 230 megawatts of wind generation in advanced development in Michigan. On December 9, 2010, Generation completed the acquisition of JDR. Attached as Exhibit 99.1 is Exelon’s press release announcing the completion of the acquisition of JDR.

The purchase price for JDR is $860 million with up to an additional $40 million payable upon commencement of construction of the three projects in Michigan. The Purchase Agreement requires that JDR have at least $8 million of working capital at closing, and the parties will true–up to that amount following the closing. Generation also will reimburse Deere for certain agreed–upon capital expenditures made prior to closing with respect to projects under development. These purchase price adjustments are estimated at approximately $33 million due to Deere.
