INTRODUCTION

This Amendment No. 4 amends and supplements the Schedule 13D filed jointly by Dr. Bjorn Jawerth (the “Reporting Person”) and Summus, Ltd. on August 23, 2000, as amended on September 8, 2000, November 20, 2000, February 8, 2001 and August 27, 2004, with respect to the common stock, par value $0.001 per share (the “Common Stock”), of Summus, Inc. (USA)(formerly High Speed Net Solutions, Inc. (the “Issuer”)). In 2001, Summus, Ltd. liquidated and distributed all of its holdings, including all of its shares of the Issuer, pro rata to the owners of Summus, Ltd. The Reporting Person, as an owner of Summus, Ltd, received a pro rata distribution of the Issuer’s shares in connection with the liquidation. Following the 2001 distribution, the Reporting Person beneficially held approximately 10,211,633 shares of the Issuer’s Common Stock. The Reporting Person’s recent sales of a portion of those shares, as disclosed herein, have reduced his beneficial ownership to less than 5% of the Issuer’s outstanding Common Stock as of February 15, 2005. The Reporting Person is no longer an executive officer or director of the Issuer. The share numbers disclosed herein reflect the Reporting Person’s ownership as of February 15, 2005, the day his beneficial ownership fell below 5% of the Issuer’s outstanding Common Stock, and, accordingly, such numbers do not give effect to the subsequent 1-for-10 reverse stock split of the Issuer’s outstanding Common Stock effected on March 16, 2005.

This statement on Schedule 13D (Amendment No.5) relates to the Common Stock of Summus, Inc. (USA), a Florida corporation (the “Issuer”). The address of the Issuer’s principal executive offices is 434 Fayetteville Street, Suite 600, Raleigh, NC 27601.
