HAYWARD, Calif.--(BUSINESS WIRE)--July 10, 2000

Data Broadcasting Corp. (Nasdaq:DBCC) today announced that eSignal quotes have been added to Nextel Online(SM), Nextel Communications' (Nasdaq:NXTL) Wireless Internet Service for businesses.

Nextel customers can now access wireless eSignal stock quotes anywhere and at any time on the Nextel Online network.

This new financial Web portal allows traders and investors to receive portable market indices; market quotes from the NYSE, Nasdaq and AMEX exchanges; breaking news; gainers and losers data; and fundamental data such as 52-week highs and lows, EPS, P/E ratios, dividend rates, yields, outstanding shares and market caps.

"Since the marketplace for WAP-enabled cellular phones is much larger than the entire PC industry, we are very excited about this opportunity with Nextel," said Chuck Thompson, senior vice president and managing director of DBC.

"This venture extends our efforts in providing active traders and investors with the latest Internet technology and financial information resources available. We strive to stay ahead of the fast-moving financial markets and continue to provide our customers with the most advanced products and services obtainable," Thompson added.

"For the traveling business professional, access to stock quotes, news and market information is important," said Greg Santoro, vice president Web-based services, Nextel Communications. "The addition of eSignal quotes to our Nextel Online Wireless Internet Service gives these users the flexibility to conduct important business seamlessly and easily while on the road."

Nextel Online is the wireless Internet solution for business: an "always connected" wireless data service that provides business customers with the tools and applications they need to access time-sensitive content and information instantly to get business done. Nextel Online links directly to eSignal's WAP service as a selection on the menu in the mini-browser.

Using Phone.com's (Nasdaq:PHCM) embedded mini-browser in a wireless phone allows the user to access eSignal's WAP-enabled financial protocol. eSignal acquires its financial information directly from the exchanges in order to ensure the fastest delivery.

eSignal is supported by Compaq Alpha Servers, reputed to be the world's fastest. DBC has multiple, redundant and geographically separate high-speed server farms in order to ensure the industry-leading reliability that customers count on and to handle the enormous increases in market data volume.

Other companies offering similar access to wireless data include GoAmerica (Nasdaq:GOAM), Aether (Nasdaq:AETH), SmartServ (OTCBB:SSOL), Datalink (AMEX:DLK), and Research in Motion (Nasdaq:RIMM).
