Tender offer extended: Exelon will continue to offer 0.485 shares of EXC for each share of NRG until Feb 25, 2009.

“Solus Alternative Asset Management LP, a New York-based
investment adviser to two funds holding 6 percent of NRG’s
stock, said it agreed with NRG’s board that the Exelon offer in
its current form was “highly conditional and undervalues NRG.”"
