  Item 5.   Other Events
            ------------
  
            On January 11, 2002, Talarian Corporation was served with a complaint
  naming Talarian and its current directors as defendants in a lawsuit filed in
  the Superior Court of the State of California, County of Santa Clara (Case No.
  CV804355). The named plaintiff in this suit is Robert Mathiason, and he seeks to
  act on behalf of a class of all holders of Talarian stock.
  
            The complaint alleges, among other things, that Talarian and its
  directors breached their fiduciary duties to Talarian's stockholders by
  approving a merger transaction with TIBCO Software Inc. and that the individual
  defendants engaged in self-dealing in connection with their approval of the
  transaction. The complaint seeks injunctive relief only, including enjoining
  consummation of the merger. The complaint does not seek an award of monetary
  damages, but does seek an award of attorneys' and experts' fees.
  
            Talarian believes these allegations are without merit, and intends to
  vigorously contest this action.
