Keller Rohrback Announces Investigation of Aspen Technology, Inc. Regarding Backdating of Stock Options -- AZPN


SEATTLE, Sept. 13, 2006 (PRIMEZONE) -- Keller Rohrback L.L.P. announces that it is investigating claims against certain executive officers and board members of Aspen Technology, Inc. ("Aspen" or the "Company") (Nasdaq:AZPN) in light of recent information concerning alleged backdating of stock options at the Company.

On September 6, 2006, Aspen announced that a subcommittee of independent directors reviewing the company's stock-option practices had found accounting errors related to certain options granted during and before fiscal 2004 and that previously issued financial statements would require restatement and should not be relied upon. The Company also stated that it would be forced to restate its financial statements to correct for the backdating of stock options, by booking approximately $31 million of additional compensation charges. Keller Rohrback's investigation focuses on whether the Company's stock option grant dates and exercise prices of stock options were manipulated by Aspen's executive officers and directors in order to boost their value to those who received them.

If you are an investor who currently owns Aspen stock, and you also held the stock at some point between 1996 to the present, the period during which the alleged backdating occurred, and you wish to discuss this case, or have questions about backdating practices, please contact paralegal Jennifer Tuato'o or attorneys Juli Farris, Elizabeth Leland, Cari Campen Laufenberg, Lynn Sarko or Gary Gotto toll free at 800/776-6044, via e-mail at investor@kellerrohrback.com, or online at www.seattleclassaction.com.
