Upon completion of the merger, each outstanding share of Coulter common stock will be automatically converted into 1.003 shares of Corixa common stock. The description contained in this Item 5 of the transactions contemplated by the merger agreement is qualified in its entirety by reference to the full text of the merger agreement, a copy of which is attached to this report as Exhibit 2.1. In connection with the execution of the merger agreement, Coulter amended its stockholders' rights plan to provide, among other things, that no person or entity would be considered to be an "acquiring person" thereunder by reason of any transaction contemplated by the merger agreement.
