they expire june 30, 2005 and the strike price is 9 bucks for a share of the common. the expiraton date has been moved out at least once over the past several months, from my recollection. i picked some more up today at 4.80. good luck. btw, they can also be traded just like the common, and there are only about a million of them out there.
Thanks for all the replies. After talking to two Ameritrade agents, I finally found the symbol is IMX+. Hopfully it will help other people. By the way, does anybody know the strike price and the expiration date for the warrents?
