TIBCO Software Inc.

This program replaces the company's previous $300 million stock repurchase program, under which approximately $27 million was still remaining.

The repurchases under the program will be made in open market or privately negotiated transactions. The manner, timing and amount of any repurchases will be determined by the company based on an evaluation of market conditions, stock price and other factors.
