Flow International to Convert Warrants

KENT, Wash., April 20 -- Flow International Corporation , the world's leading supplier of ultrahigh-pressure waterjet products, today announced its intention to convert all remaining common stock warrants issued in connection with its Private Investment in Public Equity transaction completed March 21, 2005 ("PIPE Transaction"). In connection with the PIPE Transaction, the Company issued warrants entitling the holders to purchase up to 1,747,307 shares of the Company's common stock. To date, warrant holders have purchased 421,738 shares of common stock through exercise of warrants.

The terms of the PIPE transaction allow the Company to force conversion of outstanding warrants to common stock if certain conditions are met. One of the most significant conditions is that the closing price for the Company's stock for each of the 20 consecutive trading days prior to the date of the notice of conversion exceeds $8.14. This condition has been satisfied. Another significant condition is that the shares issuable upon exercise of the warrants must be registered. This condition was satisfied when the Company's Form S-1 registration statement was declared effective on February 22, 2006. The conversion of the warrants to common stock will be completed as a cashless exercise, with each warrant holder receiving a number of shares based on the formula set forth by the warrant.

Pursuant to the terms of the warrants, the exercise date will be April 28, 2006, the fifth trading day following the day the Company notified the warrant holders of the conversion.
