ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On March 27, 2001, Chordiant Software, Inc. ("Chordiant") completed its
previously announced acquisition of Prime Response, Inc. ("Prime Response") in a
stock-for-stock transaction. Prime Response was acquired pursuant to an
Agreement and Plan of Merger and Reorganization, dated as of January 8, 2001
(the "Reorganization Agreement"), by and among Chordiant, Prime Response and
Puccini Acquisition Corp., a wholly owned subsidiary of Chordiant ("Merger
Sub"). Pursuant to the Reorganization Agreement, Merger Sub was merged with and
into Prime Response, with Prime Response as the surviving corporation (the
"Merger"). As a result of the Merger, Prime Response became a wholly owned
subsidiary of Chordiant. In connection with the Merger, each outstanding share
of Prime Response common stock was exchanged for 0.6 of a share of Chordiant
common stock, resulting in the issuance of an aggregate of approximately 12
million shares of Chordiant common stock for all outstanding shares of Prime
Response common stock. Chordiant also assumed all outstanding options and
warrants to purchase shares of Prime Response common stock.

     The Merger is intended to qualify as tax-free reorganization within the
meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and
will be accounted for as a purchase. The description contained in this Item 2 of
the Merger and the other transactions contemplated by the Reorganization
Agreement is qualified in its entirety by reference to the full text of the
Reorganization Agreement, a copy of which was previously filed as Exhibit 2.1 to
Chordiant's Form 8-K filed with the Securities and Exchange Commission (the
"Commission") on January 17, 2001.

     Prime Response is a provider of integrated relationship marketing software
solutions that enable businesses with large customer bases to create, execute
and refine highly targeted Internet, wireless and traditional marketing
campaigns that build more loyal and profitable customer relationships.

     On March 27, 2001, Chordiant and Prime Response issued a joint press
release entitled, "Chordiant Software Completes Acquisition of PrimeResponse,"
relating to the consummation of the Merger. A copy of the press release is
attached to this Report as Exhibit 99.1 and is incorporated by reference herein.
