Business Wire, June 21, 2004

PORTLAND, Ore. -- Corillian Corp. (Nasdaq:CORI), the top provider of online banking solutions to leading financial institutions, today announced that SunTrust Bank, a long-time customer of Corillian, was recently awarded the inaugural "Keynote Performance Award" in recognition for being the most reliable online banking site.

The Keynote Performance Awards are designed to honor, recognize and celebrate excellence in Web site performance. They are based on Keynote Systems E-Banking Transaction Performance Index, a Web transaction performance benchmark for improving the performance of a bank's most critical online banking services. The Index measures the total execution time and success rate for logging into an account and checking the account balance on selected Internet banking sites.

"We are extremely pleased to be recognized as the most reliable online banking site," said John McGuire, senior vice president and managing director of SunTrust Online. "We are committed to reliably providing our customers with real-time access to their accounts anytime, anywhere, and our partnership with Corillian has played a key role in fulfilling that commitment. The performance, scalability and reliability of the Corillian Voyager platform are unmatched in the industry."

"More than ever before, banks need to focus on ensuring that they deliver the highest levels of performance possible to their online banking customers," said Arnold Waldstein, vice president of marketing and business development for Keynote. "Consumers today expect high levels of online performance and reliability and frequently compare their online banking experiences to the likes of Yahoo!, EBay, Amazon.com and other well-known, high-performing consumer websites. Therefore, it is critical that banks focus on delivering world-class performance online and look beyond their traditional bank competitors in setting their standards of online banking performance excellence. SunTrust has realized this and is doing an excellent job of ensuring their underlying technology platform decisions lead to world-class levels of online performance."

Keynote's indices are recognized as benchmarks for understanding, comparing and improving Web site performance from the all-important end user perspective. They represent what a typical end user in the U.S. would experience when going to a leading online banking Web site to search for information or perform a transaction.

"The recognition that our customers receive for their online banking efforts is a validation of our industry-leading products and services," said Alex Hart, president and CEO of Corillian Corporation. "Online banking users continue to demand the highest levels of performance, reliability and usability as they manage their finances online. This recognition continues to set Corillian apart as the industry standard for online banking solutions."
