Applications in Retail, Telecom, Financial Services and Government Establish a New Market for Netezza Users

Marlborough, MA — September 3, 2008 — Netezza Corporation (NYSE Arca: NZ) today announced five advanced analytic applications developed by Netezza Developer Network (NDN) members. These applications operate in the core of the Netezza appliance where data is stored, exploiting Netezza's massively parallel processing architecture for blisteringly fast performance of complex analytics. Analytic processing previously beyond the capabilities of conventional data warehouses becomes routine with Netezza.

The newly released applications are:

• Database emulation functions for easier migration to Netezza (Edge Associates)
• Monte Carlo simulation for pricing derivatives (HCL Technologies)
• Fuzzy name matching for intelligence and fraud detection for government agencies (Multi-Threaded, Inc.)
• Dynamic re-pricing for telecommunications providers (RateIntegration)
• True business profitability management for retail and CPG companies (Pi Solutions, a Systech Solutions spinoff)

These applications perform complex analytics orders of magnitude faster than currently economically feasible. For example, with one of these applications, telecommunications companies can instantly re-rate price plans by assessing different price scenarios based on tens of millions of call detail records (CDRs).

"Netezza provides us a unique platform to bring truly differentiated applications to market. Through our NDN membership, we have been able to simplify our application development process and build complex applications faster," said Arun Gollapudi, CEO, Systech Solutions. "We see tremendous opportunity to leverage Netezza's architecture and high performance to provide our customers with the ability to solve problems that they just could not before."

The first of many in development, these applications underscore the value of the NDN: Netezza users have a rich and growing choice of applications; NDN partners have a revenue stream from their productized expertise; and Netezza brings better solutions to market.

"By providing plug-and-play solutions for complex analytic scenarios, these applications offer a rich set of options for customers," said Jim Baum, president and COO, Netezza. "Enabling this after-market of solutions will increase our momentum as we enter the mainstream."
