GLASTONBURY, Conn., April 18, 2005 -- Open Solutions Inc. (NASDAQ: OPEN), a provider of integrated enabling technologies for financial institutions, has announced the delivery of its newest product offering, the Interaction Management Center (IMC). The Interaction Management Center is a powerful browser-based relationship management application that offers a financial institutions' frontline and call center employees centralized access to CRM/business intelligence functionality, common transactional capabilities and business process management tools. From a single working environment, the IMC delivers information, functionality and transactional capabilities generally found in multiple disparate system applications. By bringing all this information together, employees now have the ability to perform frequent daily tasks more efficiently, provide higher levels of service and grow key customer/member relationships.

"Frontline employees are the face of a financial organization," said Open Solutions Product Manager, CRM and business intelligence, Lizette Nigro. "In order to optimize each and every contact, they need easy access to a considerable amount of information and functionality. The Interaction Management Center brings them the most meaningful information, functionality and transactional abilities from separate applications such as CRM, platform, transactional, fraud detection systems and more all in a single workflow-enabled environment."

The system provides in-depth information while the customer/member is in front of the employee, which allows the employee to offer timely, relevant and personalized products and services immediately. Along with the direct benefits of managing contacts and improving relationships, the application's Session Management feature tracks and reports interactions to provide a rational basis for decisions about business processes and performance.

"For years, our company has built solutions based on a 'people-centric approach' to the business of financial services," said Michael Nicastro, senior vice president of Marketing and Product Development for Open Solutions. "Employees at financial institutions all over the country are tabbing back and forth from one technology application to another during a single interaction with a consumer to get information or to process transactions. Customer and member service is not about accounts; it's about the total relationship. IMC puts a clear and complete view of that total relationship in front of the institution employee and gives them the ability to provide fast and accurate service from a central graphical interface."

Louis Hernandez, Jr., Open Solutions chairman and CEO, said, "Our mission is to help our industry extend the power of tools currently available to better serve customers and members. Open Solutions believes in innovation born out of business needs. This solution is a move toward truly unlocking the institution's delivery channels and allowing our clients to connect back office and frontline employees. The Interaction Management Center is one of the first products of its type. It has been designed to aggregate disparate silos of data while and tying together CRM and transactional environments to provide an unparalleled level of integration to the sales and service environment. Open Solutions is proud to lead the charge of revolutionizing the financial services marketplace with innovative technology products and services such as IMC."
