Pursuant to the terms of that certain Agreement and Plan of Merger (“Merger Agreement”) dated August 21, 2009 by and among TIBCO, Touchdown Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of TIBCO (“Merger Subsidiary”), DataSynapse and certain other parties listed on Annex 1 to the Merger Agreement, the Merger Subsidiary merged with and into DataSynapse, resulting in DataSynapse becoming a wholly-owned subsidiary of TIBCO.
