  Acquisition or Disposition of Assets

  On April 23, 2002, TIBCO Software Inc., a Delaware corporation ("
  TIBCO
  " or the "
  Registrant
  "), acquired Talarian
  Corporation, a Delaware corporation ("
  Talarian
  "), by the statutory merger (the "
  Merger
  ") of Talarian with and into Panther Acquisition Corp., a Delaware corporation and wholly owned subsidiary of TIBCO. The Merger
  was accomplished pursuant to the Agreement and Plan of Merger, dated as of January 4, 2002, among TIBCO, Panther and Talarian, and a related Certificate of Merger (collectively, the "
  Merger Agreements
  "). The Merger occurred
  following the approval of the Merger Agreements by the stockholders of Talarian pursuant to a stockholders meeting held on April 23, 2002 and satisfaction of certain other closing conditions. As a result of the Merger, TIBCO became the owner of 100%
  of the issued and outstanding shares of Talarian common stock and each outstanding share of Talarian common stock was converted into the right to receive (i) $2.65 in cash, without interest, and (ii) 0.21793 of a share of TIBCO common stock (the
  "
  Merger Consideration
  ").
  A total of approximately $59,318,183 and 4,878,193 shares of TIBCO common stock will
  be paid and issued to the former Talarian stockholders and optionholders in exchange for the acquisition by TIBCO of all outstanding Talarian common stock and all unexpired and unexercised options to acquire Talarian common stock. Options to acquire
  Talarian common stock were assumed by TIBCO in the Merger and remain outstanding as options exercisable for the Merger Consideration.
  No fractional shares of TIBCO common stock will be issued in connection with the Merger. In lieu thereof, any holder of Talarian common stock that would otherwise have been entitled to receive a fractional share of TIBCO common stock will
  paid the cash value of such fractional shares, which will be determined by
  multiplying
  (i) the fractional share of TIBCO common stock that any holder of Talarian common stock would otherwise be entitled to receive as a result of the
  Merger (after aggregating all fractional shares of TIBCO common stock that such holder would otherwise be entitled to receive)
  by
  (ii) $9.91, representing the average of the closing sales prices for one share of TIBCO common stock as
