ComStock Introduces New DataFeed Solutions

New High Speed Network and Mitigated Options Service Address Industry Volume Increases and Client Content Needs

February 22, 2005, New York - ComStock, an Interactive Data Company (NYSE:
IDC) and a leading provider of real-time global market data, today unveiled two initiatives designed specifically to help clients cope with rapidly increasing market data volumes.

The first initiative features the launch of a new high-speed datafeed network designed to carry data rates of up to 42 megabits per second (Mbps). The new network, called IP4, was developed in response to rapidly growing market data volumes.

"In 2004, ComStock saw data volumes grow by more than 106%," said David Brukman, ComStock's chief technology officer. "And for 2005, we expect that this rapid growth rate will continue, with projections of additional expansion of up to 9% a month."

At 42 Mbps, the IP4 network is projected to accommodate the full breadth of ComStock's high-speed datafeed service called XpressFeed beyond 2006. The coverage encompasses more than 350 global exchanges and sources across all asset classes, including full tick coverage of all options data from The Options Price Reporting Authority (OPRA) and tick data from the major Electronic Communications Networks (ECNs). Delivered via a full or fractional DS3, IP4 is currently deployed at 18 Mbps. ComStock plans to increase capacity to 42 Mbps by June 2005.

"The IP4 network is initially aimed at those clients that need bandwidth intensive data sources such as full OPRA or ECN data," said Don Finucane, vice president of Marketing and Product Management for ComStock. While data volumes from these sources have grown rapidly, the IP4 network is engineered to handle such volumes and more without mitigation and with ultra-low latency. "Due to ComStock's intelligent publish/subscribe technology, clients that require a smaller subset of the datafeed, such as North American equity data, may not need to increase their bandwidth in the short-term," added Finucane, "We are proactively working with clients to develop custom, cost-effective capacity plans."

New Mitigated Options Service

ComStock also introduced a new Mitigated Options Service. This service currently provides best bid and offer data and is aimed at clients that do not require the full options data service. The new Mitigated Options Service represents a 50% bandwidth savings from the full OPRA data service, which currently represents more than one-third of all data carried on XpressFeed.

"Our Mitigated Options Service was developed as result of a survey we conducted regarding our client's options data needs," said Finucane. "For many clients, the new mitigated service meets all of their data requirements; allowing them to receive the highest quality data while leveraging their existing communications networks."

The Mitigated Options Service is currently available on IP4 and will be integrated into ComStock's other datafeed networks by spring.
