     This Amendment No. 2 amends the Schedule 13D filed on February 2, 2007 (as
amended by Amendment No. 1 thereto filed on April 4, 2007, and this Amendment
No. 2, the "Schedule 13D") and is being filed on behalf of Third Point LLC, a
Delaware limited liability company (the "Management Company"), Daniel S. Loeb,
an individual ("Mr. Loeb"), and Third Point Offshore Fund, Ltd., a Cayman
Islands limited liability exempted company (the "Offshore Fund", and together
with Mr. Loeb and the Management Company, the "Reporting Persons"). This
Amendment No. 2 relates to the Common Stock, par value $0.01 per share, of Flow
International Corporation, a Washington corporation (the "Company"). The
Management Company is the investment manager or adviser to a variety of hedge
funds and managed accounts (such funds and accounts, collectively, including but
not limited to the Offshore Fund, the "Funds"). The Funds directly own the
Common Stock to which the Schedule 13D relates, and Mr. Loeb and the Management
Company may be deemed to have beneficial ownership over such Common Stock by
virtue of the authority granted to them by the Funds to vote and to dispose of
the securities held by the Funds, including the Common Stock.

Item 4.   Purpose of Transaction.

     On April 23, 2007, Mr. Loeb sent a letter to the Board of Directors of the
Company advising the Board that the Management Company, on behalf of the Funds,
would be prepared to make an offer for the purchase of the entire Company. In
the letter, Mr. Loeb requested that the Board waive the restrictive provisions
of Mr. Stephen Light's employment agreement with the Company so that Mr. Light
would be in a position, if he so chose, to work with the Management Company to
develop a business plan and valuation upon which the Management Company's bid
could be based.

     The foregoing description of Mr. Loeb's letter is qualified in its entirety
by reference to the text of the letter, which is filed herewith as Exhibit 99.1.

Item 7.   Material to be Filed as Exhibits.

  99.1    Letter, dated April 23, 2007, from Mr. Loeb to the Board of Directors
          of the Company.

  99.2    Power of Attorney granted by Mr. Loeb in favor of James Kelly, Justin
          Nadler, Zachary Snow and Keith Waller, dated December 1, 2006.
