ITEM 5.   OTHER EVENTS

     On May 16, 1996 the Company entered into and received
additional equity capital under Regulation S Offshore Transaction
Subscription Agreements with two investors (the "Foreign
Purchasers") pursuant to an offshore private placement offering
of 600,000 shares of the Company's Common Stock at a gross
purchase price of $511,875, or $0.853125 per share (the
"Offering").  The gross purchase price per share represented a
negotiated discount of 35% from the closing price for the Common
Stock of $1.3125 per share as reported in the Nasdaq SmallCap
Market on the day immediately prior to the execution of
subscription agreements by the Foreign Purchasers and the
Company.  From the total gross proceeds of $511,875, the Company
paid escrow fees to an independent escrow agent of $2,500 plus
fees payable to certain placement agents and a distributor in the
aggregate amount of $51,187, resulting in net proceeds to the
Company of $458,188.  The Offering was terminated by the Company
at the close of business on May 16, 1996.
