Australian Banks Join Carreker in Equity Ownership of Nationwide Cash Outsourcing Company.

Business Editors

DALLAS--(BUSINESS WIRE)--Oct. 9, 2002

Carreker Corporation (Nasdaq:CANI), a leading provider of technology and consulting solutions for the financial industry, announced today that the three large Australian-based banks using the services of Cash Services Australia (CSA) have become equity owners in CSA.

Westpac Banking Corporation, Commonwealth Bank of Australia, and Australia and New Zealand Banking Group Limited each assumed ownership of 25 percent of the company, with Carreker retaining 25 percent.

Carreker helped the banks create and launch CSA as a strategic outsourcing service provider to manage two costly cash handling functions for all three banks: armored carriers and first-line ATM maintenance. Additionally, CSA utilizes Carreker technologies that streamline and automate the cash-ordering process for the banks. The resulting efficiencies have reduced the banks' cash handling costs while improving service to their customers.

More Australian banks are expected to join CSA, producing additional economies of scale, and CSA plans to expand its service offerings to include other value-added cash management services.

David Pegley, Chief Executive Officer of Cash Services Australia, said, "A great deal of planning and work went into the creation of CSA and we are pleased to see such significant results. We look forward to adding more services around cash processing to further enhance the value proposition for the participating banks."

J. D. (Denny) Carreker, Chairman and CEO of Carreker Corporation, said, "CSA is a prime example of our ability to deploy consulting and technology solutions to help banks collaborate on strategic sourcing entities. We are committed to helping our clients seek additional sourcing opportunities."

Added Mike Hansen, President of Carreker Corporation and a CSA board member, "The Australian banks have shown tremendous initiative in collaborating for mutual gain and customer advantage. Cash handling is an increasingly costly and complex function that can benefit from shared entities such as CSA."
