Item 1.01 Entry into a Material Definitive Agreement.

On December 17, 2012, Midwest Generation and Midwest Generation’s indirect parent, Edison Mission Energy (“EME”), filed voluntary petitions under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Northern District of Illinois (the “Bankruptcy Court”).  See Item 1.03.  The commencement of voluntary cases by Midwest Generation and EME are events of default under the operative documents that govern Midwest Generation’s lease of the Powerton Generating Station, in Pekin, Illinois, and Units 7 and 8 of the Joliet Generating Station, in Joliet, Illinois.  Such filings permit the owner lessors of the Powerton and Joliet facilities, the owner lessors’ equity owners, and the holders of the pass-through certificates issued to finance the leases to exercise certain rights and remedies against Midwest Generation and EME.

On December 16, 2012, Midwest Generation and EME entered into a forbearance agreement with the Powerton and Joliet leases’ owner lessors, the owner lessors’ equity owners, and approximately 72 percent of the holders of the outstanding pass-through certificates.  A copy of the forbearance agreement is attached hereto as Exhibit 10.1.  Under this agreement, the parties agreed to forbear from exercising certain rights and remedies against Midwest Generation or EME on account of their Chapter 11 filings for 60 days.  In addition, the parties agreed that Midwest Generation will pay the ratable portion of the rent due under the leases attributable to the period between December 17, 2012, and January 2, 2013, on February 15, 2012.  The Bankruptcy Court approved the forbearance agreement on December 18, 2012.

Item 1.03 Bankruptcy or Receivership.

On December 17, 2012, Midwest Generation, two of Midwest Generation’s wholly-owned domestic subsidiaries, EME, and certain other wholly-owned domestic subsidiaries of EME (collectively, the “Debtor Entities”) filed voluntary petitions for relief under Chapter 11 of the Bankruptcy Code in the Bankruptcy Court (collectively, the “Chapter 11 Cases”).

The Chapter 11 Cases are being jointly administered under the case caption In re Edison Mission Energy et al., No. 12-49219 (JPC) (Bankr. N.D. Ill.).  Midwest Generation will continue to operate its business as a “debtor-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. In order to assure ordinary course operations, Midwest Generation has sought, and received, approval from the Bankruptcy Court for a variety of “First Day” motions, including authority to pay employees and vendors in the ordinary course, authority to maintain bank accounts, and other customary relief.

Item 9.01.  Financial Statements and Exhibits.

(d)  Exhibits.

10.1 Forbearance Agreement dated as of December 16, 2012 by and among Midwest Generation and certain owner lessors, owner lessors’ equity owners, and holders of outstanding pass-through certificates.
