2005 Open Solutions Annual Client Conference Garners More Than 1,000 Attendees; Educational Sessions, Informative Discussions and Product Demonstrations Highlight Conference.

GLASTONBURY, Conn. -- Open Solutions Inc. (NASDAQ: OPEN), a provider of integrated enabling technologies for community financial institutions, recently hosted its 2005 Annual Client Conference in San Diego from April 16 to 20, attracting more than 1,000 executives from financial institutions in the U.S. and Canada. Additionally, there were 55 conference sponsors who took part in a vendor Solutions Expo, where clients and prospective clients could visit and learn about complementary technology products. This year marks the highest participation ever at the Open Solutions annual event.

During the four-day conference, key industry initiatives were discussed, and new products and services were previewed such as Open Solutions' new Interaction Management Center (IMC). The latest technology updates and business trends in the financial arena, client best practices, focus groups, product demonstrations and educational breakout sessions on Open Solutions' full product line were also part of the company's agenda. Client-specific sessions offered interactive dialog with Open Solutions' management, development and service teams to openly discuss ideas and develop technology-based strategies for growth and efficiency.

Prior to the opening day of the conference, client bank and credit union CEOs and presidents participated in a two-day Senior Executive Forum. This peer-to-peer forum provided high-level briefings and interactive sessions and was designed to promote greater communication while generating open feedback and discussion on how Open Solutions can better meet the needs of its clients.

Senior Vice President Retail Banking, Community Bank, Staunton, Va. and outgoing Open Solutions Client Association Executive Committee Chairman, Benny Werner, said, "The input we are able to provide Open Solutions during this annual meeting is invaluable. Clients are given the chance to network with their peers, discuss best practices and participate in training classes, workshops and focus groups. There is no better forum in which we can accomplish this. We also review new technology specifications to help determine what features and functionality are most important to be included. Every year, I leave the conference with a sense that as a group we have assisted in providing the technical specifications that will help every financial institution be better equipped in this competitive marketplace."

The Monday morning Welcome Address was given by Louis Hernandez, Jr., chairman and CEO of Open Solutions. He discussed the state of the marketplace, Open Solutions' service initiatives and gave a general update on the company. Debbi Fields, founder of Mrs. Fields Cookies, followed Hernandez providing an entrepreneurial view of what it takes to start, grow and sell your own business.

"The business intelligence, industry insights and regulatory watch sessions provided a great opportunity to learn more about industry trends and discuss practical business strategies and solutions," said Dawn L. Ruggles, president and CEO of VAC Federal Credit Union in Shreveport, La. "As the financial services industry becomes more competitive we must be equipped with the best technology to provide our members a real advantage. Open Solutions understands what issues are facing our institutions and designed the sessions and meetings to address those concerns.

"Additionally, the conference gave me an opportunity to meet and discuss my credit union's own personal strategy and needs with the Open Solutions client care team. I could actually see results while attending the conference and this was a big plus since we recently migrated to the Open Solutions' credit union platform," Ruggles said.

Roy Firestone, renowned speaker, interviewer and host of ESPN's Up Close, kicked Tuesday morning off with his versatile and original talents.

According to Open Solutions Chairman and CEO, Louis Hernandez, Jr., the annual Open Solutions Client Conference is a great learning opportunity for both Open Solutions' employees and our clients. "The conference gives us an opportunity to discuss industry trends and business strategies with our clients as well as solicit feedback." Hernandez said. "Over the years, the client conference has grown with our offerings. Our product managers and business development teams are available to answer questions about our solutions and receive input that allows them to design new products and services and enhance existing solutions that provide better service and positively affect our clients' bottom line.

"Open Solutions' mission is to give financial institutions the power to leverage technology to assist them in their strategic efforts. In this regard, we strive to build working partnerships with our clients and provide them with technology solutions that continue to meet their ever-changing needs. The focus groups, breakout sessions and product demonstrations give our clients a chance to share knowledge and further develop strategies to implement the best technology available. This year's conference far exceeded our expectations for client feedback, educational value and attendance. We look forward to working with our clients' suggestions as we continually strive to provide them with the technology solutions to meet their needs."
