Item 5.   Other

Recent Developments

     On July 9, 2003, Mirant Americas Generation LLC ("MAG") supplemented its
exchange offer (the "Exchange Offer") commenced on June 2, 2003, for its
outstanding 7.625% Senior Notes due 2006 (the "Existing Notes"), as amended on
June 20, 2003 and June 30, 2003, pursuant to Supplement Number 1 to the Second
Amended Offering Circular dated July 9, 2003 (the "Supplemented Offering
Circular").

     The Exchange Offer does not contain changes from the Second Amended
Offering Circular dated June 30, 2003 to the consideration being offered to
holders of Existing Notes. The Supplemented Offering Circular, however,
contains changes to the proposed new credit facilities of MAG and its ultimate
parent, Mirant Corporation ("Mirant"), as well as certain supplemental
information.

     On July 9, 2003, Mirant also supplemented its offer to exchange its 8.25%
Senior Secured Notes due 2008 for its outstanding 2.5% Convertible Senior
Debentures due 2021 and 7.4% Senior Notes due 2004 pursuant to Supplement
Number 1 to the Second Amended Offering Circular and Disclosure Statement and
Solicitation of Acceptances of a Prepackaged Plan of Reorganization dated July
9, 2003 (the "Mirant Exchange Offers").

     Consistent with Mirant's previous filings, the soliciation of acceptances
of the pre-packaged plan of reorganization contains substantially the same
terms as the terms in the Mirant Exchange Offers.

     The Expiration Date for the Exchange Offer and the Mirant Exchange Offers
is July 14, 2003.
