         Effective as of February 2, 2001, the Registrant was acquired by
DoubleClick Inc., a Delaware corporation ("DoubleClick"), by way of a merger
(the "Merger") in which the Registrant merged with and into DoubleClick and
ceased to exist. In connection with the Merger, each share of common stock of
the Registrant outstanding immediately prior to the consummation of the Merger
was exchanged for $3.45 in cash and .2829 shares of DoubleClick common stock,
and DoubleClick assumed all of the Registrant's stock options and warrants
outstanding at the effective date of the Merger, based on a .4975 exchange
ratio. Accordingly, as of the date hereof, there are no holders of record of
Common Stock of the Registrant.
