Bay Federal Credit Union Selects Open Solutions' Relational Core Processing Suite.

GLASTONBURY, Conn. -- Open architecture solution gives credit union the ability to grow significantly enhancing member relations

Bay Federal, a full-service credit union in Capitola, Calif., with more than 52,000 members and more than $436 million in assets, has selected Open Solutions' The Complete Credit Union Solution (R) to address its core data processing needs. After more than a year of research, Bay Federal credits the open architecture and the ability to develop and deploy new products and services, as well as Open Solutions' high level of responsiveness to customers as the influencing factors for their decision to implement The Complete Credit Union Solution. Open Solutions Inc.(R) (NASDAQ: OPEN) is a provider of integrated enabling technologies for financial institutions. They offer a fully-featured strategic product platform that integrates core data processing applications, built on a single centralized Oracle(R) relational database, with Internet banking, cash management, CRM/business intelligence, financial accounting tools, in-house integrated credit card processing, electronic image/item processing, Check 21, interactive voice response, and payment and loan origination solutions.

"After carefully reviewing and analyzing The Complete Credit Union Solution for more than a year, we realized that Open Solutions' core values are very much aligned with Bay Federal's," Carrie Birkhofer, president and CEO of Bay Federal, said. "Our key focus is on building meaningful relationships with our members through the interactions of our employees. Likewise, Open Solutions continuously makes improvements and enhancements based on the suggestions of its clients."

The open architecture of The Complete Credit Union Solution is designed to make it easy for financial institutions like Bay Federal to integrate with third parties. Birkhofer continued, "Having the ability to interface with 'best of breed' third parties for loan origination and other ancillary services, such as pc banking, further enables the credit union to best meet the needs of our growing member-base. Additionally, we believe Open Solutions' will make it easy for our member service representatives to navigate the system."

Bay Federal cites small business loans and deposits as its next major growth opportunity. "Open Solutions has a proven track record of providing these types of member business services," Birkhofer said. "Partnering with Open Solutions gives us the ability to implement better mortgage lending products and services, as well as small business accounts. Additionally, we will be able to expand our credit card portfolio offerings and offer better home banking and audio response services."

Bay Federal also selected several Open Solutions' products including asset/liability management, the financial accounting suite, cView (CRM/business intelligence) and e-Commerce Banker(TM)(eCB) (cash management and Internet banking).

"We wanted a suite of products from a technology partner that could integrate our delivery channels, as well as our repositories of member information -- whether from our deposit operations or our extensive lending portfolios," Birkhofer said. "We were impressed with eCB's functionality, which is fully integrated with the core system; the sophistication of the Asset Liability module (ALM), which should greatly improve our forecasting abilities, and finally, cView, which will allow us to improve our one-to-one marketing and better tailor our member services. We believe using the Open Solutions' platform will better enable us to meet our growth strategies. We expect to grow aggressively at a rate of 20 percent per year."

Louis Hernandez, Jr., Open Solutions chairman and CEO, said, "The management team at Bay Federal Credit Union has a clear growth strategy set in place. Our relational core data processing, as well as our complementary product offerings, will play a significant role in helping Bay Federal meet and exceed its business goals. We believe that an open platform at the core of an institution's technology infrastructure is key to its continued success. We are pleased that Bay Federal Credit Union has selected our company, and we look forward to a long-standing business partnership."
