ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

     In January 1998, the Registrant completed a series of independent, but 
related transactions (the "Transactions") with certain individuals owning 
equity interests in CombiMatrix Corporation ("CombiMatrix"), Greenwich 
Information Technologies LLC ("Greenwich Information Technologies"), 
MerkWerks Corporation ("MerkWerks"), and Soundview Technologies Incorporation 
("Soundview Technologies").  CombiMatrix, Greenwich Information Technologies, 
MerkWerks, and Soundview Technologies are collectively referred to 
hereinafter as the "Affiliates."

     Prior to entering the Transactions, the Registrant held a majority 
interest as follows: (i) 51.4% of the outstanding common stock of Soundview 
Technologies; (ii) 69.5% of the outstanding common stock of MerkWerks; and 
(iii) 51.4% of the outstanding common stock of CombiMatrix.  The Registrant 
also held a minority interest of 30.02% of the membership interests in 
Greenwich Information Technologies.

     In the Transactions, the Registrant acquired additional interests in 
each of the Affiliates in exchange for newly-issued shares of the 
Registrant's common stock.  Although the shares of the Registrant's common 
stock were restricted and issued pursuant to the private placement exemption 
from registration under Securities Act of 1933, as amended, the Registrant 
agreed to register the resale of such shares with the Securities and Exchange 
Commission.  A registration statement of Form S-3 covering those shares was 
filed by Registrant on February 2, 1998 (File No. 333-45397).

     There is no public market for any of Affiliate equity interests acquired 
by the Registrant.  Among the factors the Registrant considered in 
determining the offer price for the equity interests in a particular 
Affiliate were that Affiliate's intellectual property rights, prices at which 
equity interests in an Affiliate have been sold in prior private 
transactions, estimates of the business potential and earnings prospects of 
the Affiliate and its industry in general, an overall assessment of that 
Affiliate, and an assessment of that Affiliate's management.

     The Transactions consisted of a total of a number of agreements entered 
into with holders of securities in the Affiliates.  In certain situations, a 
single agreement involved exchanges for interests in two or more of the 
Affiliates.  Although the first transaction occurred on January 14, 1998, the 
Transactions, as a whole, were not deemed to be material until the vast 
majority of the transactions were completed on January 27, 1998.  A detailed 
breakdown of the Transactions is as follows:

(1)    The number of shares of the Registrant's common stock exchanged was 
       based on the prior ten day average of the stock's trading price on the 
       Nasdaq National Market.
(2)    Because Greenwich Information Technologies is a limited liability 
       company, equity is expressed in terms of percentage of membership 
       interests rather than shares. In addition, Per Share Offer Price is 
       expressed in total valuation of Greenwich Information Technologies as 
       was offered by Sellers to determine the total value of each Seller's
       membership interest.
(3)    All Points Management Trust provides consulting services to the 
       Registrant.
(4)    Dr. Ching has provided consulting services to the Registrant.
(5)    Mr. Lackey provides consulting to the Registrant.  Mr. Lackey also 
       has acted as a finder in connection with a private placement offering 
       made by the Registrant in December 1997.
(6)    May include certain shares held in trust as trustee and/or held 
       jointly with minor children.


     The Transactions did not cause nor result in the Registrant acquiring 
control of any Affiliate.  The Registrant already had control of three of the 
Affiliates--Soundview Technologies, MerkWerks, and CombiMatrix--prior to 
completing the Transactions.  After completion of the Transactions, the 
Registrant's interests in the Affiliates increased as follows: (i) 66.7% of 
the outstanding common stock of Soundview Technologies; (ii) 89.6% of the 
outstanding common stock of MerkWerks; (iii) 52.7% of the outstanding common 
stock of CombiMatrix; and (iv) 33.33% of the membership interests in 
Greenwich Information Technologies.
