Item 1.01. Entry into a Material Definitive Agreement

     On April 6, 2005, Ship Acquisition Corp. (“Ship”), a subsidiary of Open Solutions Inc. (the “Registrant”), purchased substantially all of the assets of S.O.S. Computer Systems, Inc. (“S.O.S”) pursuant to the terms of an Asset Purchase Agreement (the “Asset Purchase Agreement”), dated as of April 6, 2005, among Ship, S.O.S., the Clark Lindsay Ballantyne Trust , the Laura Ballantyne Warner Trust, the Dunster Family Trust and David Smart. S.O.S., headquartered in Orem, Utah, is a provider of in-house core data processing and associated support and services for approximately 120 credit unions across the United States. The aggregate consideration paid for the assets was $11,400,000, of which $1,368,000 is to be held in escrow for two years to secure indemnification obligations of S.O.S., subject to a purchase price adjustment based on S.O.S.’s net current assets as of April 6, 2005 and the collection of accounts receivable.

     The terms of the Asset Purchase Agreement were determined on the basis of arms-length negotiations. Prior to the execution of the Asset Purchase Agreement, to the best of the Registrant’s knowledge, neither the Registrant nor any of its affiliates, nor any of its directors or officers, nor any associate of any such director or officer, had any material relationship with S.O.S.

     The foregoing summary description of the terms of the transaction is qualified in its entirety by reference to the Asset Purchase Agreement, which is attached as Exhibit 10.1 to this Current Report on Form 8-K.
