LINCOLN, Neb., July 12, 2004--National Bank & Trust has chosen the Information Technology, Inc. (ITI) unit of Fiserv, Inc. (Nasdaq:FISV) as its new banking technology partner. Headquartered in Wilmington, Ohio, the $665 million financial institution credited ITI's scalable, integrated suite of products and services as the primary reason behind its decision.

"Our old core system provider handled our teller and platform systems, but used separate, third-party products for item processing, Internet banking and telephone banking," said Craig Fortin, National Bank & Trust Senior Vice President & CFO. "That hampered our efficiency ratio, especially whenever we had an issue with one of the systems. We wanted everything under one umbrella, so we turned to ITI to help us streamline operations."

National Bank & Trust currently offers a broad range of financial services through its 18 Ohio locations. "With ITI's seamless solutions and real-time capabilities, we'll not only save time and money, but deliver greater customer satisfaction," said Fortin.

Offering account management, platform and teller, e-commerce, document management and business intelligence solutions, ITI's Premier system expands the traditional definition of a "core solution" by incorporating vast amounts of customer data within a seamlessly integrated and comprehensive product suite. A new browser-based user interface and advanced architecture drive an array of industry leading features and functionality, combined with new and powerful tools that significantly enhance a bank's ability to respond to customers and cross-sell effectively.

"We credit much of our industry-wide popularity to a renewed desire to associate with a stable and experienced technology partner, one that offers flexible products and profitable services that address banking's challenges, both today and tomorrow," explained Kurt Kuhl, ITI Senior Vice President. "National Bank & Trust can expect to add value to their customers' experience, and more satisfied customers contribute to any organization's bottom line. ITI is looking forward to a long and very effective partnership."
