ISDEX® Internet Stock Index ® Calculation Change Announced

Date 01/12/2000

The Kansas City Board of Trade is announcing a change in the method used to calculate internet.com's ISDEX® Internet stock index®. Effective with the close of business on December 31, 2000, the limit of any single stock's capitalization will be reduced from 10% to 3.5%.

"We took this action to maintain the ISDEX as the leading Internet stock index," said Alan Meckler, chairman of internet.com. "As Internet stock valuations have contracted, the influence of a small group of companies on the index has increased. This change ensures that the index will continue to reflect the performance of the entire Internet economy."

The 50 stocks in the ISDEX are chosen from each of the 13 Internet sectors, including advertising; consultants and designers; content and communities; e-commerce enablers; e-tailers; financial services; ISP's; Internet services; performance software; search and portals; security; speed; and bandwidth and wireless. As a group, the ISDEX stocks represent over 80% of the market capitalization of the roughly 400 Internet stocks.

The ISDEX is reviewed quarterly to add or delete stocks that best represent the Internet diversity for investors. If there is an intra-quarter merger or acquisition of companies within the index, stocks may be added to the ISDEX immediately or soon after. In this way, the ISDEX has been the most up-to-date and dynamic Internet stock index.

ISDEX, The Internet Stock Index, created by internet.com Corporation, is the leading and the oldest Internet stock index in the marketplace.
