Item 2.  Acquisition or Disposition of Assets.

     Effective August 22, 1997, Harbinger Corporation, a Georgia corporation
(the "Company"), acquired from FD Engineers and Constructors, Inc., a California
corporation ("FD"), all of the outstanding capital stock of Acquion, Inc., a
California corporation ("Acquion") and a wholly owned subsidiary of FD (the
"Acquisition"). The Acquisition was consummated in accordance with the terms of
a Stock Purchase Agreement ("Stock Purchase Agreement"), dated August 22, 1997,
among the Company, FD and Fluor Corporation, a Delaware corporation ("Fluor").

     The consideration paid by the Company in connection with the Acquisition
was approximately $12.0 million in cash, which amount is subject to adjustment
based on the net assets of Acquion on the Closing Date. In connection with the
Acquisition, which was accounted for under the purchase method of accounting,
the Company expects to take an $11-$14 million charge in the third quarter of
1997 for in process research and development and integration related charges. 
The Company financed the Acquisition through its working capital.

     The total consideration paid in the Acquisition was determined through arms
length negotiations between representatives of the Company and FD. Neither the
Company nor any of its affiliates had, nor to the knowledge of the Company, did
any director or officer or any associate of any such director or officer of the
Company have, any material relationship with FD, Acquion or Fluor prior to the
Acquisition. The tangible assets acquired in the Acquisition were used in
developing Maintenance Repair and Operations ("MRO") software catalogs and
content, and the Company intends to use such assets for substantially the same
purpose.

     Acquion's strategic focus is on supply chain management and purchasing
related services utilizing electronic commerce technology. To date, Acquion has
provided innovative MRO electronic supplier catalogs that offer up to date
information. Acquion offers clients robust MRO catalog content and cataloging
expertise as evidenced by their catalog content for leading chemical,
petrochemical and industrial corporations and universities. These electronic
catalogs are among the first to be integrated into today's enterprise and legacy
computer systems. Acquion was formed in 1994 as a subsidiary of FD and is
headquartered in Greenville, South Carolina.

     A complete description of the Acquisition is contained in the Stock
Purchase Agreement filed as Exhibit 2(a) and incorporated herein by reference.
