Ljubljana, Slovenia., July 8, 2008 —- Netezza (NYSE Arca: NZ) today announced that TUŠ Telekom will standardized its data warehouse on Netezza’s market-leading data warehouse appliance technology. Slovenia’s newest supplier of mobile telecommunications, broadband, IPTV and VoIP will use the Netezza system for advanced analytics such as customer segmentation, churn prediction, pricing simulations and usage control and will soon extend this to include revenue assurance.

Klemen Lavrac, Business Intelligence and Data Warehousing Manager at TUŠ Telekom explained, “One of the ways we can gain an advantage over our competitors is with the sophisticated analysis of our customer database, network usage and traffic. In order to be effective, this analysis has to be fast, accurate and consistent. So, we decided to move our data to a fully integrated Netezza data warehouse. The project was scoped on a forward-looking quantity of data and high expectations for customer responsiveness. Our systematic survey of the market has shown that our requirements are best served by Netezza, whose technology is, in our opinion, the most advanced in the business intelligence (BI) and data warehousing market by several years.”

Joe Napoli, Director of International Distribution at Netezza added, “The data warehouse is being implemented by our Slovenian partner, crmT, a specialist in BI and data warehousing. TUŠ Telekom believes that the combined effect of crmT’s expertise and support along with Netezza’s technology gives them a substantial advantage in a very competitive telecoms industry. The Company aims to become the operator providing most advanced services in Slovenia.”
