Company Appoints Jon Niess Vice President of International Operations

Framingham, Mass.—March 21, 2005—Netezza Corporation today announced the expansion of its international operations with the opening of a Sydney, Australia office and the appointment of Jon Niess to vice president of international operations. Niess will lead a global team based in Bracknell, England and Sydney.

Netezza’s international expansion follows a record-setting year in which the Company realized substantial growth and momentum in the data warehousing industry. Netezza’s success was underscored by a significant increase in market adoption of its Netezza Performance Server® (NPS®) data warehouse appliance. With more than twenty years of international business experience, Niess will enable Netezza to build on this momentum by focusing on international strategies, sales and operations in Europe and the Asia Pacific region.

“By expanding our international presence in Europe and now in the Asia Pacific region, we are building on our success in North America and the United Kingdom,” said Jit Saxena, CEO and co-founder of Netezza. “Data-intensive organizations such as Amazon.com, Ahold, Orange UK and Caudwell Communications are already realizing the power of the NPS system in these markets. The addition of Jon Niess to the Netezza team allows us to reach even more global opportunities in the data warehousing market and brings us closer to our installed customer base.”

Before joining Netezza, Niess served as senior vice president of worldwide sales operations at Vignette Corp. At Vignette, he was responsible for worldwide software revenue and managed the successful integration of several acquisitions into the company’s operations. Niess’ professional experience also includes a variety of executive sales and operational positions, including area vice president of Oracle Corporation.

“Customers worldwide are realizing the business value of the NPS system and appreciate the simplicity of the appliance model,” said Niess. “Our continued international expansion demonstrates our commitment to global customers and partners.”

The Netezza Performance Server system is the market-leading data warehouse appliance, built specifically to analyze terabytes of detailed data 10 to 50 times faster than existing data warehouse options, at half the cost. The NPS system stores, filters and processes terabytes of records within a single unit, analyzing only the relevant information for each query. Netezza has placed the CPU power next to the data, allowing the NPS system to speed through processes that would occupy most data warehouse systems for hours, or even days, thereby enabling dramatic increases in productivity across the organization. Customers who have recognized the performance benefits of Netezza’s approach include Acxiom Corporation, Ahold USA, Amazon.com, Cingular Wireless, CNET Networks, Epsilon, Orange UK, Premier, Inc., Shoppers Drug Mart Corporation and The TJX Companies.
