DAB bank and Interactive Data Extend Relationship

Financial market data now also provided for bank’s new trading application

FRANKFURT, Germany – January 14, 2009 – Interactive Data Corporation (NYSE: IDC), a leading provider of financial market data, analytics and related services, today announced that its Managed Solutions business will extend and expand its 10-year relationship with DAB bank AG. Interactive Data will continue to supply the German online broker with a broad range of quote and reference data via Market Data Gateway, its market data platform. The data is made available on the DAB bank public website, www.dab-bank.de, and privately to the bank’s employees via internal information systems.

Interactive Data will also supply real-time, delayed and end-of-day quote data to DAB Profi Trader, a new trading application. The modular application provides registered private users with charts and other decision-relevant visual representations of data.

In addition, the new agreement provides for the migration of all of DAB bank's Internet-based market data applications to Interactive Data’s Market Data Gateway. Until now, DAB bank has received market data for several individual applications using an application programming interface (API) for the Java programming language.

“Reliably delivered quote information is essential for our top traders, who are using our new DAB Profi Trader with growing enthusiasm,” said Niki Bat, Products & Services Division manager at DAB bank. “After the positive experiences we have had with the applications and services provided by Interactive Data since 1998, we really look forward to our continued cooperation.”

“The extension of our agreement with DAB bank AG and the associated expansion of our services for the Profi Trader application demonstrate the strength of our current relationship”, said Carsten Dirks, managing director of Interactive Data Managed Solutions. “We are pleased that DAB bank has selected PrimeDeveloper, our comprehensive development services package, and will broaden the scope of its use of our Market Data Gateway to encompass its entire current suite of online applications and website.”
