ST. LOUIS & CHICAGO – December 15, 2003 – SAVVIS Communications (NASDAQ: SVVS), a leading global managed services provider, and HyperFeed Technologies, Inc. (NASDAQ: HYPR), a developer of ticker plant technology, software and managed services, today announced a partnership to launch the SAVVIS Data Delivery Utility, a global network distribution service that enables cost-effective, low-latency delivery of real-time financial content. In addition, the new service will offer the industry’s first end-to-end Service Level Agreements (SLAs) that guarantee network performance, and SAVVIS maintains exclusive rights to distribute Data Delivery Utility worldwide.

SAVVIS’ Data Delivery Utility seamlessly integrates HyperFeed’s Managed Exchange Platform Services (MEPS) and H!BOX software with SAVVIS’ global infrastructure and management and monitoring systems. This combination allows the industry to “plug into” a high-performance, yet turnkey utility service for the normalization, data-basing, integration and transmission of high performance, real-time direct data sources running on a “five 9’s” private network featuring multicast. Exchanges, financial institutions, content providers, and applications developers will find Data Delivery Utility to be a compelling service for the consumption and transmission of real-time, directly sourced financial information.

For example, the Data Delivery Utility collects raw data feeds from the major trading venues and data sources in North America including: American Stock Exchange, Archipelago ECN, Chicago Board of Trade, Chicago Mercantile Exchange, Island ECN, Montreal Stock Exchange, NASDAQ, New York Board of Trade, New York Mercantile Exchange, NYSE, OPRA, and the Toronto Stock Exchange. These content sources are then dynamically cleansed, normalized, and compressed using HyperFeed technology and delivered to users via SAVVIS’ global multicast network. The first North American exchanges will be live on Data Delivery Utility by the end of 2003, with additional exchanges rolled out globally in the first half of 2004.

“Financial institutions, market data vendors, and exchanges alike are investing heavily to modernize their architecture to capture, normalize, and disseminate market data in support of electronic trading,” said Tim Lind, senior analyst with the Tower Group. “We believe institutions will increasingly complement aggregate data products with direct exchange feeds as the simplicity, reliability, and total cost of the proper network and data management infrastructure becomes more affordable.”

“The Data Delivery Utility service is a fluid, decentralized approach to financial data delivery that will fundamentally change the way financial content is processed, transmitted, and delivered,” said Paul Pluschkell, President of HyperFeed. “It also empowers market participants by giving them more control over the data sources they select. By leveraging our technology across SAVVIS’ proven, high-performance financial network in a managed utility approach, we created the most direct, cost-conscious solution for financial content distribution.”

The Data Delivery Utility service is completely data vendor agnostic and built on a fully-meshed network model that provides economical and ubiquitous service with full security. Financial content is collected directly from the major trading venues and data sources globally and is continuously transmitted in an uninterrupted stream that can be multicast to any customer with an on-site HyperFeed H!Box. Via entitlements and permissioning systems, customers access only the data they elect to receive and are not forced to take bundled sets of financial content. Finally, included with the Data Delivery Utility are adaptors to a number of widely used middleware platforms that allow for easy integration with off-the-shelf industry applications or proprietary applications and systems.

“The Data Delivery Utility is a perfect example of SAVVIS’ high-performance global infrastructure and award-winning management systems integrating with innovative application technologies to create a compelling value-added managed utility service,” said Rob McCormick, Chairman & CEO of SAVVIS. “Data Delivery Utility further expands our service offerings and provides the industry with a reliable, secure, and economical financial content distribution service where the cost is spread and shared among many.”
