PALO ALTO, Calif. , February 28, 2000 - Informatica Corporation (NASDAQ: INFA) today announced that Netcentives (NASDAQ: NCNT) is using Informatica PowerMart® to achieve greater insight into its ClickRewards membership as well as enhance reporting to its merchants by consolidating online data generated by more than four million consumer members. A leading developer of e-marketing infrastructure software and services, Netcentives joins other prominent Internet companies that have chosen Informatica to enable e-business data analysis including eBay, CNET, Inktomi, Preview Travel, Priceline.com and WebMD.

Netcentives uses Informatica PowerMart to consolidate transactional, Web and e-mail click-through data generated by members’ use of its flagship ClickRewards™ Online Shopping Network. ClickRewards allows merchants such as barnesandnoble.com to implement e-commerce rewards programs to develop loyalty among their online customer bases.

"In order to consolidate huge amounts of diverse consumer data generated by our ClickRewards program, we needed a robust infrastructure capable of managing data on millions of customers daily,” said Tim Catlin, senior vice president of research and development at Netcentives. “We were attracted to Informatica by its proven scalability. An even more compelling and valuable feature we've since uncovered is PowerMart’s ability to manage a fast-growing number of data sources and targets. This flexibility saves hours, sometimes days compared to hand coding a similar system.”

Through the implementation of its e-business analysis system, Netcentives has been able to:

• Provide merchant partners with greater insight into their customers' buying behavior. With PowerMart, Netcentives can quickly generate granular reports for its merchant partners highlighting patterns in customer buying behavior. By providing its merchant partners with reports indicating how their marketing promotions influenced customer buying behavior over a certain period of time, Netcentives enables them to more effectively plan and develop future promotions.

• Attract key merchants to its ClickRewards program. As the number of online merchants continues to grow and Internet commerce becomes increasingly competitive, online merchants are looking for tools they can use to keep customers coming back. Through its e-business analysis system, Netcentives is able to market the value and effectiveness of its ClickRewards program, enabling it to continue partnering with some of the Web's leading vendors.

• Significantly reduce development time. After considering the internal development of an e-business analysis system, Netcentives determined that choosing Informatica would provide a competitive advantage by significantly reducing time to market. Instead of months of custom development, the Informatica solution was up and running in a matter of weeks.

Based on its success to date in leveraging e-business data from its ClickRewards program, Netcentives plans to extend PowerMart’s capabilities to its other corporate and commerce loyalty networks.
