(1)  Less than 1%.

(2)  In order to insure that the representations, warranties and covenants
     made under the Raven Merger Agreement (as defined below) are not
     breached, and in order to provide a source of indemnification of the
     Company pursuant to the Raven Merger Agreement, such Selling Stockholder
     deposited 37,741 shares of Common Stock in an escrow account pursuant to
     a warranty escrow agreement until the earlier of (1) the date of the
     first audit of the combined enterprises' financial statements is
     completed, (2) August 26, 1998 or (3) the date set forth in a written
     direction executed by the Company and Brian Raffel and Steven Raffel.

     The Company has entered into an agreement and plan of reorganization
(the "Raven Merger Agreement") with Raven Software Corporation of which Brian
and Steven Raffel and Michael Crowns were the sole shareholders, and has
entered into a license and personal services agreement with Bruce Willis. 
Other than such contracts, and the fact that many of the Selling Stockholders
are either employees, or relatives or spouses of employees, of Raven, which
became a wholly onwed subsidiary of the Company in August, 1997 pursuant to
the Raven Merger Agreement, none of the Selling Stockholders has had a
material relationship with the Company within the past three years.
