Press Release Source: Schiffrin & Barroway, LL P Shareholder Class Action Filed Against TIBCO Software, Inc. By The Law Firm of Schiffrin & Barroway, LLP Tuesday May 31, 6 :00 pm ET

RADNOR, Pa ., May 31 /PRNewswire/ -- The following statement was issued today by the law firm of Schiffrin & Barroway, LLP:

Notice is hereby given that a class action lawsuit was filed in the United States District Court for the Northern District of California on behalf of all purchasers of the common stock of TIBCO Software, Inc . ("TIBCO" or the "Company") (Nasdaq: TIBX - News) from September 21, 2004 through March 1, 2005, inclusive (the "Class Period").

If you wish to discuss this action or have any questions concerning this notice or your rights or interests with respect to these matters, please contact Schiffrin & Barroway, LLP (Marc A . Topaz, Esq . or Darren J . Check, Esq.) toll-free at 1-888-299-7706 or 1-610-667-7706, or via e-mail at info@sbclasslaw .com .

The complaint charges TIBCO and certain of its officers and directors with violations of the Securities Exchange Act of 1934. TIBCO engages in the development and marketing of software solutions for the integration of business information, processes, and applications in various industries outside the financial services market . More specifically, the Complaint alleges that the Company failed to disclose and misrepresented the following material adverse facts which were known to defendants or recklessly disregarded by them : (1) that the Staffware PLC ("Staffware") integration was not yet complete ; (2) that the failed integration of Staffware was causing material disruptions for the Company ; (3) that the failed Staffware integration caused a paralysis of leadership in the Company's European management, which resulted in a lack of execution in all European markets for the Company ; (4) as such, the Company was unable to close any licensing deals that resulted in revenue of more than $5 million ; and (5) that TIBCO did not maintain an adequate system of internal financial, operational or disclosure controls so as to reasonably assure the accuracy, completeness and veracity of the Company's public statements and representations to investors.

On March 1, 2005, defendants announced that TIBCO's results for the first quarter of fiscal year 2005 were well below guidance. Even worse, during TIBCO's first quarter of fiscal year 2005 conference call, defendants revealed that Staffware not only remained unintegrated, but because of integration- related problems, European sales had been paralyzed . News of this shocked the market. Shares of TIBCO fell $1 .86 per share, or 20.9 percent, to close at $7.04 per share on unusually heavy trading volume .

Plaintiff seeks to recover damages on behalf of class members and is represented by the law firm of Schiffrin & Barroway, which prosecutes class actions in both state and federal courts throughout the country . Schiffrin & Barroway is a driving force behind corporate governance reform, and has recovered billions of dollars on behalf of institutional and individual investors from the United States and around the world . For more information about Schiffrin & Barroway, or to sign up to participate in this action online, please visit http://www.sbclasslaw .com.

If you are a member of the class described above, you may, not later than July 25, 2005, move the Court to serve as lead plaintiff of the class, if you so choose. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation . In order to be appointed lead plaintiff, the Court must determine that the class member's claim is typical of the claims of other class members, and that the class member will adequately represent the class. Under certain circumstances, one or more class members may together serve as "lead plaintiff ." Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff .
