Item 1.01. Entry into a Material Definitive Agreement

     On April 21, 2005, Open Solutions Inc. (the “Registrant”) entered into an Employment Agreement (the “Employment Agreement”) with Louis Hernandez, Jr., its Chairman of the Board and Chief Executive Officer. Pursuant to the Employment Agreement, which has a three-year term, the Registrant will pay Mr. Hernandez an annual base salary of $400,000, subject to increase at the discretion of the Board of Directors. The Employment Agreement also provides for Mr. Hernandez to receive an annual cash bonus based on the achievement of certain performance targets, with a target payment of 75% of his base salary and a maximum payment of 150% of his base salary. Mr. Hernandez has agreed not to compete with the Registrant’s business or to solicit any of the Registrant’s employees or clients during the 12-month period following the termination of his employment. If Mr. Hernandez’s employment is terminated without cause or with good reason, he will receive a payment equal to the full amount of his target bonus for the year of termination and will continue to receive his base salary and benefits for one year after termination. If Mr. Hernandez’s employment is terminated following a change of control (as defined in the Employment Agreement), he will receive a payment on the date of his termination equal to two times the sum of his base salary at the time and his target bonus for the year of termination. Upon his termination following a change of control, Mr. Hernandez will also continue to receive benefits for two years and any outstanding stock options held by him will become fully vested.
