ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

     On August 30, 1999, Flycast Communications Corporation, a Delaware
corporation ("Flycast") acquired InterStep, Inc., a Massachusetts corporation
("InterStep"), pursuant to the merger of Fremont Acquisition Corporation
("Merger Sub"), a Massachusetts corporation and wholly owned subsidiary of
Flycast with and into InterStep. As a result of the merger, InterStep became a
wholly owned subsidiary of Flycast. In the transaction, which will be accounted
for as a pooling of interest, Flycast issued 480,337 shares of common stock to
InterStep shareholders. Of the 480,337 shares of common stock, 47,558 shares are
held by an escrow agent to serve as security for the indemnity provided by
certain shareholders of InterStep.

     A copy of the Agreement and Plan of Reorganization, by and among Flycast,
InterStep, Merger Sub and certain shareholders of InterStep, dated August 30,
1999, is attached hereto as Exhibit 2.1.
