Washington Trust Uses Open Solutions' Image-based Item Processing Solution, ISCheck(TM)

Glastonbury, Conn. - Open Solutions Inc.(R) (NASDAQ: OPEN), a provider of integrated enabling technologies for financial service providers across the United States and Canada, announced that The Washington Trust Company, Rhode Island's largest independent bank, is successfully using ISCheck, its image-based item processing solution. Washington Trust is one of the first financial institutions in Rhode Island to take advantage of Check 21 services.

"ISCheck is a dependable, cost-effective item processing solution that provides an excellent platform for future growth and supports our item processing plans," said Vice President Retail Support Services, David Jardin. "It is a complete Check 21 solution that offers a fully-featured product suite, enabling us to meet the challenges and opportunities of today's payment systems environment."

ISCheck, a comprehensive image-based item processing solution, is designed to allow financial institutions to customize and add features such as image exchange, branch capture, remote deposit, document imaging and image lockbox. ISCheck can be implemented as an in-house operation or outsourced through one of Open Solutions' regional item processing centers. Open Solutions also offers a blended solution for institutions that need to outsource only certain functions.

"Washington Trust has been actively participating in the FedForward(SM) and FedReturn(SM) programs since January of this year," Jardin said. "Each institution's Check 21 strategy is unique to its specific needs and market. Given our market and proximity to the Federal Reserve (First District, Boston), geographic considerations were not as important as the overall operational efficiencies and cost effectiveness that a migration to FedForward and FedReturn processing provides. Embracing technology to streamline operations has a direct, positive impact on how we serve our customers and the products we can provide."

"When Check 21 legislation cleared in October 2003, financial institutions had only one year to develop an imaging strategy," said Louis Hernandez, Jr., chairman and CEO of Open Solutions. "Open Solutions has been at the forefront of developing and implementing cost effective Check 21 solutions, and we are pleased to see that so many institutions are exploring and realizing the benefits and cost reductions presented by today's technology in the post-Check 21 environment. Open Solutions understands these needs and has created customized solutions to provide the most cost effective clearing paths, unlimited access to image archives and fraud detection. Open Solutions is dedicated to providing the technology and service our clients need to process transactions efficiently in this era rendered by Check 21."

The Washington Trust Company also uses Open Solutions enterprise-wide data processing platform, The Complete Banking Solution(R) and the cView(TM) relationship management tool.
