ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

On August 1, 2001, Pegasus Technologies, Inc., a South Dakota corporation
("Pegasus") and a majority-owned subsidiary of KFx Inc., a Delaware corporation
("KFx"), entered into an agreement with Pavilion Technologies, Inc., a Texas
corporation ("Pavilion"), providing for (i) the purchase by Pegasus of certain
Pavilion assets relating to Process optimization for the utility based boiler,
gas turbine and power production and process steam turbine (the "Segment"); (ii)
Pegasus' rights and access to certain Pavilion assets, personnel and services
relating to the Segment; and, (iii) the licensing to Pegasus of certain Pavilion
intellectual property related to the Segment in a limited field of use.

The acquisition was made pursuant to the terms and conditions of an asset
purchase and license agreement, dated as of July 31, 2001, by and among
Pavilion, Pegasus and KFx (the "Purchase Agreement"). The Purchase Agreement
provided for a base price of $9,500,000 in cash payable to Pavilion in
installments through July 31, 2003. Additionally, Pegasus shall pay Pavilion
royalties of up to $5,500,000 between August 1, 2001 and October 31, 2005, based
on software licenses sold by Pegasus. The duties and obligations of Pegasus
under the Purchase Agreement are guaranteed by KFx.

The consideration provided for in the Purchase Agreement was determined by
Pegasus after a complete review of the business of the Segment and negotiations
between representatives of Pegasus, KFx and Pavilion. The initial payment for
the purchase was financed through an advance on an existing contract with
Cinergy Corporation. The remainder of the purchase price is expected to be
financed through future investments in Pegasus.

The Segment provides enterprise decision optimization solutions to customers by
utilizing its patented technology, engineering and consulting expertise.
