Q2 Software’s Response to Complaint AUSTIN, TX, January 29, 2008 – Q2 Software, Inc. is aware of the complaint filed by S1 Corporation and has submitted timely responses and affirmative defenses accordingly to the appropriate judicial court. We intend to aggressively defend ourselves against these false accusations. We see this filing as nothing more than a desperate act by a desperate company attempting to distract us from our primary focus of helping financial institutions become more competitive. As we continue to pursue the legal course of events, we will provide additional comments when and where appropriate.
