ITEM 5.  OTHER MATERIALLY IMPORTANT EVENTS.

     On February 20, 1997, Music Tones Ltd. (the "Company") and Simplex Medical
Systems, Inc. ("Simplex") signed a Letter of Intent whereby the Company will
acquire all of the outstanding shares of USC in exchange for restricted shares
of the Company's common stock.

     If this transaction is consummated, the Company will issue 3,453,000
restricted shares of its common stock in an amount which will represent
approximately 47.9% of its outstanding common stock in exchange for all of the
issued and outstanding shares of USC.  The Company will also cancel 32,250,000
of its currently outstanding common stock just prior to the closing.

     Simplex Medical Systems, Inc., a developmental stage company, is engaged in
the development, acquisition, marketing and manufacturing of medical diagnostic
products, saliva diagnostic products, biologic products for blood banking, bulk
pharmaceuticals, specialty chemicals and agricultural chemicals.

     Simplex has applied for patents to acquire rights to certain technologies
and inventions for non-invasive diagnostic products, specifically devices for
detection of human immunodeficiency virus (HIV), hepatitis B and other diseases.
Simplex believes that the non-invasive collection and analysis of biological
fluids, specifically, the device for collection of saliva is expected to replace
many test regimes for diagnostic products that are presently in use.

     The closing of this transaction is subject to the execution of a definitive
agreement which will contain various representations and warranties of each 
party and which will be subject to the approval of the directors of each 
company.
