ITEM 2.    ACQUISITION OR DISPOSITION OF ASSETS

(a)     On December 31, 1997, pursuant to the terms of the Technology Purchase
Agreement, by and between Spatial Technology Inc. (the "Company") and
Three-Space Limited, a limited company organized under the laws of England
("TSL") (the "Purchase Agreement"), the Company acquired from TSL all right,
title and interest to all software, designs, copyrights, documentation, patents,
trade secrets and other technology or other intellectual property rights that
(i) are incorporated into the ACIS 3.0 software and its related husks (the
"Existing Assets") and (ii) were developed, or were in the process of being
developed, by TSL as of December 31, 1997 pursuant to the Development Agreement
(the "Prior Development Agreement"), by and between the Company and TSL, dated
June 26, 1987, as amended (the "In Process Research") (the Existing Assets and
the In Process Research being collectively referred to as the "Assets"). In
connection with the acquisition of the Assets pursuant to the Purchase
Agreement, the Company granted TSL certain registration rights (the
"Registration Rights") as set forth in the Registration Rights Agreement, by and
between the Company and TSL, dated as of December 31, 1997. Such Registration
Rights Agreement provides that if the Company proposes to register any of its
securities under the Securities Act of 1933, either for its own account or for
the account of other security holders, TSL, or its assignees, is entitled to
notice of the registration and is entitled to include, at the Company's expense,
shares of Common Stock held by it (as defined below).

     The consideration provided by the Company in connection with the foregoing
transaction consisted of the following: (i) $850,625.00 in cash and (ii) the
issuance of an aggregate of 250,000 shares of common stock of the Company (the
"Common Stock"). The purchase price was determined through negotiations between
the Company and TSL. The Company funded the cash portion of the consideration
paid to TSL from general working capital.

     In connection with the foregoing transaction, the parties forever released
and terminated in their entirety the Prior Development Agreement and the
Marketing Agreement, by and between the Company and TSL, dated May 31, 1989, and
entered into the Software Consulting Agreement, by and between the Company and
TSL, dated as of December 31, 1997 (the "Consulting Agreement"). Pursuant to the
terms of the Consulting Agreement, TSL will provide certain consulting services
to the Company in connection with the development of geometric modeling software
and components; the Company will own all right, title and interest to any
technology developed by TSL in connection therewith.
