Item 2.           Acquisition or Disposition of Assets

      On December 14, 2001 (the "Effective Time"), Netegrity, Inc. ("Netegrity")
completed its acquisition of DataChannel, Inc., a Washington corporation
("DataChannel"), pursuant to an Agreement and Plan of Merger dated October 24,
2001 by and among Netegrity, LKN Acquisition Corp., a Delaware corporation and a
wholly-owned subsidiary of Netegrity (the "Merger Subsidiary"), and DataChannel,
as amended by the First Amendment to the Agreement and Plan of Merger, dated as
of December 3, 2001 and the Second Amendment to the Agreement and Plan of
Merger, dated as of December 7, 2001 (as amended, the "Merger Agreement").

      Pursuant to the Merger Agreement, the Merger Subsidiary merged with and
into DataChannel at the Effective Time, whereupon DataChannel became a
wholly-owned subsidiary of Netegrity (the "Merger"). In connection with the
Merger, Netegrity issued an aggregate of 2,500,000 shares of its Common Stock,
$.01 par value per share (the "Merger Shares") and paid a total of $15 million
in cash in exchange for all of the outstanding shares of DataChannel capital
stock. A total of 250,001 Merger Shares have been placed in escrow in accordance
with the terms of a related escrow agreement to secure indemnification
obligations of the DataChannel stockholders under the Merger Agreement.
Netegrity has agreed to register with the Securities and Exchange Commission all
of the Merger Shares for resale by the DataChannel stockholders within 60 days
of the Effective Time.

      Netegrity paid the cash portion of the consideration for the acquired
capital stock from its working capital. Netegrity expects to treat the Merger as
a purchase for accounting purposes.

      Prior to the Merger, DataChannel was a provider of data management
platform solutions designed to enable enterprises to gather, integrate,
personalize and extend mission critical enterprise application and content to
their employees, customers and business partners. Netegrity currently intends to
continue DataChannel's use of the acquired assets constituting plant, equipment
or other physical property.

      The terms of the Merger Agreement, including the amount of consideration
paid by Netegrity, were determined pursuant to arms' length negotiations between
Netegrity and DataChannel. Prior to the closing of the Merger, none of
Netegrity, its affiliates, officers or directors, or any associate of any such
officer or director, had any material relationship with DataChannel or any of
the stockholders of DataChannel.

      The foregoing description of the Merger Agreement does not purport to be
complete and is qualified in its entirety by reference to the full text of the
Merger Agreement, which is included as Exhibit 2.1 to this Current Report on
Form 8-K.
