CHICAGO--(BUSINESS WIRE)--Sept. 21, 1999--

SLP InfoWare, a leading provider of knowledge-based customer retention application solutions, today announced that Sonofon (Denmark) has purchased SLP's Churn/Customer Profiling System(TM) (Churn/CPS).

Churn/CPS, an automated and scalable customer retention software application, will provide Sonofon with the ability to identify and approach customers that are vulnerable. "We selected SLP because of their reputation and expertise in churn management and their outstanding track record in delivering significant results in a very short time frame," said Kurt Weiss, customer service director for Sonofon.

Churn/CPS uses knowledge of customer characteristics with quantified customer value to identify at-risk customers and reduce customer churn. Lene Weje Knappman, an internal consultant in Sonofon's customer relations department, said, "We were looking for a software solution to proactively reduce customer churn. We carefully evaluated two software products during a six-week test on real customer data and selected Churn/CPS based on six major criteria, which included the software's adaptability to market dynamics and the company's expertise in business implementation."

"We are pleased to have been selected to help Sonofon achieve a significant amount of net additions by proactively retaining customers. We share a common vision of customer retention with Sonofon and other SLP InfoWare customers in Europe, the US, Puerto Rico and Egypt," said Michel Rocher, chief operation officer for SLP.
