Open Solutions Announces International Strategic Reseller Partnership with R Systems Inc.

GLASTONBURY, Conn., Aug. 31, 2005 — Open Solutions Inc.® (NASDAQ: OPEN), a provider of integrated enabling technologies for financial institutions, announced a strategic reseller partnership with R Systems Inc., an information technology and business process outsourcing company serving clients worldwide with global delivery capabilities. The partnership with R Systems will further expand Open Solutions’ presence in the international market. Open Solutions recently announced its International Operations Department headed by industry veteran Wayne Ginn.

R Systems International Ltd., is headquartered in El Dorado Hills, Calif. and Noida, India. Through its banking and finance vertical, Indus Soft, R Systems is involved in providing total solutions and consumer finance software products to the banking industry in Asia, the Far East, the Middle East and Europe.

As a result of this reseller partnership, R Systems will sublicense Open Solutions’ relational core data processing solutions and integrated strategic products in its target markets, and Indus Soft will be responsible for implementing, customizing, localizing and supporting the products.

Open Solutions Chairman and CEO Louis Hernandez, Jr., said, “This reseller relationship will enable Open Solutions to gain entry into markets where R Systems is already strong, giving our globalization plans a foothold overseas. We believe that our open core data processing platform solution and integrated product suite will not only increase our association in these markets, but will also provide-R Systems with the ability to offer a more comprehensive solution to its customers. Having resellers in the international market space is part of our ongoing strategy to introduce our technologies abroad. This reseller partnership, along with the recent addition of global financial industry veteran Wayne Ginn as vice president of International Operations, will further our international presence.”

Open Solutions provides enabling solutions to domestic and international financial institutions, offering some of the most advanced functionality, technology and service in today’s market. Its relational database technology suite was designed to be an open architecture application, creating the flexibility necessary to run an agile, customer-focused institution. The product suite delivers real-time core data processing, business functionality and business intelligence capabilities that have efficiencies for both the front and back offices.

“We looked closely at Open Solutions’ product offering and fully understand its value and efficacy,” said R Systems Chairman and CEO Rekhi Singh. “Open Solutions’ relational core data processing solution is best suited for financial institutions looking to grow their businesses, streamline operations and remain competitive. We believe its best-of-breed enabling platform offers flexibility, scalability and ability to address future industry requirements. Open Solutions’ advanced applications satisfy these needs and have surpassed our expectations and industry requirements.”

“This is a great opportunity for both companies,” Ginn said. “R Systems already has a strong presence internationally. This agreement will give them the opportunity to resell the Open Solutions’ product line and thus increase Open Solutions’ presence in the international market. It’s a win-win for both companies.”

Open Solutions is staying ahead of global trends in technology by providing international financial institutions with open, real-time solutions. The enterprise applications have been designed to improve customer relationship management, reporting and technology integration.
