AllSouth Federal Credit Union Selects Open Solutions' Core Processing Suite; Credit Union Selects Open Architecture, Flexible Core to Enable Growth.

GLASTONBURY, Conn. -- AllSouth Federal Credit Union has selected Open Solutions Inc.(R)'s (NASDAQ:OPEN) The Complete Credit Union Solution(R) (TCCUS), a relational core data processing platform for credit unions, to address its enterprise wide data processing needs. With $352 million in assets and more than 89,000 members, AllSouth selected Open Solutions after an extensive review of core technology providers.

"We wanted a modern, flexible technology platform that would put us on the same operational level as our competitors," said AllSouth President and CEO William (Bill) Koehler. "The solutions we reviewed from other vendors just were not flexible enough and as architecturally sound as The Complete Credit Union Solution. We did not want to be encumbered by hardware constraints or a vendor's inability to integrate with differing technology applications. In addition to having the best fit for core processing, the suite of ancillary products from Open Solutions was also very attractive. Throughout the selection process, Open Solutions emerged as a true partner, and that was important as we look toward long term growth and the coming competitive landscape."

AllSouth also selected Open Solutions' Asset/Liability Management and Financial Planning products, as well as the Accounts Payable and General Ledger suite, Interactive Voice Response, Consumer and Mortgage lending, Investor Reporting and the Report Wizard and Dynamic Messaging (CRM/business intelligence) applications.

Koehler said, "We looked at specific areas of the credit union, whether it was member access points or our ability to complete investor reporting, and we were able to identify a complementing Open Solutions application that bolstered our operational efficiency or access to information. Knowing more about our members has historically aided in our ability to give them better service. The technology offering from Open Solutions was built on that premise as well."

According to Open Solutions product managers, relational database technology helps credit unions understand and improve relationships with members. By offering access to detailed data, the technology gives our credit union's staff a complete picture of each member's relationships with the institution. TCCUS is designed to mirror the way a credit union does business and to easily accommodate any changes, internally or externally, that arise in the future.

Senior Vice President and General Manager of Open Solutions' Credit Union Group Gary Daniel said, "Credit unions need technology applications that offer efficient, scalable processing; easily-accessed, relevant member information and the ability to offer members more competitive products and services. For more than a decade, Open Solutions has been meeting those needs. TCCUS delivers long-term value through increased functionality and flexibility. With Open Solutions at the core, AllSouth is the benefactor of many new opportunities for growth, streamlined operations and tools to assess its financial position in real-time."

Louis Hernandez, Jr., Open Solutions Chairman and CEO, said, "Member satisfaction is a cornerstone of the mission at AllSouth, and we believe better technology solutions will bolster their stellar staff in progressing that mission. Open Solutions is proud to have been selected by the AllSouth Federal Credit Union as their technology platform of choice. We are committed to providing each of our client institutions with the tools to maximize core competencies and accelerate their business strategies. We look forward to our role in AllSouth's growth."
