SEC Approves New Nasdaq Data Product For Securities Professionals - PostData Created In Response To Widespread Demand

The Nasdaq Stock Market® today announced that the Securities and Exchange Commission (SEC) approved on January 16, 2002, a rule filing to enable Nasdaq® to offer a new online package for broker/dealers and institutional investors called Nasdaq PostData^SM. The product is scheduled to launch on March 18, 2002.

"Nasdaq PostData was created in response to widespread demand from market participants," said Adena Friedman, Senior Vice President of Nasdaq Data Products. "Prospective clients have told us that the information provided by PostData will give them a decisive advantage in an increasingly competitive marketplace."

Nasdaq PostData consists of the following trading data reports:

• Nasdaq Volume PostSM displays for subscribers' precise, daily share-volume, in selected Nasdaq securities, from the prior trading day;
• Monthly Volume Summaries that rank the top 50 market participants by industry sector, security type, or total and block volume; and
• Daily Issue Data that provides a summary of the previous day's activity for every Nasdaq issue, including price, total shares outstanding, dividend data, and more.

Due to the proprietary nature of the reports, PostData resides in the Secure Data section of the nasdaqtrader.com Web site, to which admittance is restricted by password. All data contained in these reports, except the Daily Issue Data Report, is based on information obtained from the Nasdaq Automated Confirmation Transaction ServiceSM (ACT^SM)-Nasdaq's system for reporting trades in Nasdaq securities-making it the most accurate data available.

To view a sample Web report of PostData, go to www.nasdaqtrader.com and choose "Hot Topics", then "Nasdaq PostData" Broker/dealers and institutional investors that have questions should contact the Nasdaq Trader Help Desk at (800) 777-5606.
