SAN RAFAEL, Calif.--(BUSINESS WIRE)--April 13, 2004

Fair Isaac Corporation (NYSE:FIC) today announced that Charles M. Osborne will join the company as chief financial officer, following the promotion of current CFO Ken Saunders to chief operating officer of international and emerging markets. The transition will take place during Fair Isaac's third fiscal quarter, and builds upon the talent of Fair Isaac's management team while delivering additional management focus to the company's strategic growth initiatives.

Osborne will oversee all financial, accounting, internal audit, investor relations and information systems activities for Fair Isaac. Prior to joining the company, he served in executive and financial leadership positions at prominent organizations including Deluxe Corporation, McLeodUSA and Graco, Inc.

"I'm excited to be joining Fair Isaac at a time when the company's unique brand of analytics is fast becoming an essential ingredient of success for more businesses and industries on a global level," said Osborne. "I look forward to the opportunity to contribute to the company's continuing growth and build upon its impressive track record of delivering consistent value to its shareholders."

Saunders, who has served as Fair Isaac's CFO since the company's merger with HNC Software in 2002, will now be responsible for leading the development and execution of Fair Isaac's aggressive growth strategies in a number of emerging areas, including those focused on insurance, healthcare and government markets. Also, Saunders will assist the company with its global growth strategies, including providing local leadership to its European operations.

"This is a tremendous and timely opportunity to both ensure our growth initiatives receive the smart, dedicated leadership they require and add another high-caliber talent to our management team," said Tom Grudnowski, CEO of Fair Isaac. "Chuck Osborne brings the financial leadership experience and strategic brainpower we need to build upon Ken's success as CFO, and his proven ability to deliver strong financial leadership during times of rapid change fits perfectly with our plans to continue pursuing an aggressive growth strategy throughout 2004 and beyond."

Prior to joining the University of Minnesota Foundation in 2000 as CFO and vice president of finance, Osborne served as vice president of corporate human resources, vice president and general manager and CFO for McLeodUSA/Ovation Communications, Inc., an Iowa-based provider of business and residential telecommunications services. He helped lead and manage Ovation's efforts to raise capital in 1998, managed McLeodUSA's acquisition of Ovation Communications, Inc. in 1999, and led all Minnesota telephone operations for the combined company during the year that followed.

Prior to joining McLeodUSA, Osborne served as president and chief operating officer for Graco, Inc., a Minneapolis-based manufacturer of fluid distribution systems for industrial and commercial applications.

Osborne spent 17 years in executive leadership with Deluxe Corporation, the largest printer of personal checks in the U.S., serving as CFO for 13 years. During his tenure, Deluxe grew in annual revenues from $400 million to nearly $2 billion. He was a key driver of an aggressive growth strategy that involved 14 acquisitions which opened important market opportunities outside of check printing, eventually leading two of the company's largest non-check-printing units.

Before joining Deluxe, Osborne began his corporate finance career at Deloitte & Touche LLP, rising quickly to its management ranks. He has also served as a professor of accounting and finance at the University of Minnesota, University of St. Thomas and William Mitchell College of Law. He holds a BS degree in business and a Master of Business Taxation degree from the University of Minnesota.
