CAMBRIDGE, Mass., Sep 13, 2002 /PRNewswire-FirstCall via COMTEX/ --

Company refutes erroneous article in internet newsletter

Aspen Technology, Inc. (Nasdaq: AZPN - News) today issued a statement discrediting an article that appeared in an internet newsletter covering process automation, which stated that AspenTech was for sale.

Larry Evans, Chairman and CEO said, "It is our normal policy not to comment on market rumors about matters such as acquisitions and other material events. However, this article included blatantly false information that the company was for sale and that an investment bank, JP Morgan, had circulated a prospectus. This information is completely untrue and the concerns this article caused among our employees and other constituents warranted issuing this statement.

"We are executing on a strategy intended to return us to operating profitability and positive cash flow as quickly as possible and I am confident that the recent changes we have implemented have put us on the right track."

The Company noted that this statement is an exception to its policy of not commenting on market rumors, and that in the future it will maintain its policy of not commenting on rumors.
