IRVINE, Calif.,June 6, 2006 — Edison Mission Group (EMG) and its indirect subsidiary, Edison Mission Energy (EME), announced today the closing of EME’s previously announced private offering of $500 million aggregate principal amount of its 7.50% Senior Notes due 2013 (the “2013 Senior Notes”) and $500 million aggregate principal amount of its 7.75% Senior Notes due 2016 (the “2016 Senior Notes” and, together with the 2013 Senior Notes, the “Senior Notes”). EMG and EME also announced the completion of EME’s previously announced cash tender offer and consent solicitation for EME’s outstanding 10% Senior Notes due August 15, 2008 (the “2008 Senior Notes”-CUSIP No. 281023AK7) and 9.875% Senior Notes due April 15, 2011 (the “2011 Senior Notes”-CUSIP No. 281023AG6) (collectively, the “Existing Senior Notes”).

EME has used the net proceeds of the offering of the Senior Notes, together with cash on hand, to purchase $368.9 million in aggregate principal amount of the 2008 Senior Notes (representing approximately 92.2% of the previously outstanding 2008 Senior Notes) and $595.6 million in aggregate principal amount of the 2011 Senior Notes (representing 99.3% of the previously outstanding 2011 Senior Notes) that were validly tendered pursuant to the tender offer and consent solicitation prior to 5:00 p.m., New York City time, yesterday, the expiration date of the tender offer and consent solicitation. The net proceeds of the offering of the Senior Notes, together with cash on hand, were also used to pay related tender premiums. The total tender premiums paid on all Existing Senior Notes validly tendered were $106.8 million, and the total consent fees paid on all Existing Senior Notes validly tendered at or prior to 5:00 p.m., New York City time, on May 17, 2006, were $28.8 million.
