                               AMENDMENT NUMBER 1
                                       TO
                            ASSET PURCHASE AGREEMENT

         The parties hereto agree to amend that certain Asset Purchase
Agreement, dated as of October 30, 2000, by and among them (the "Agreement"), as
provided in this Amendment.

         Subsection 4.14(b) of the Agreement is hereby amended to read as
follows:

                  HSNS agrees to provide to Summus, under the terms of
                  the Loan Agreement, an additional $235,000 on
                  October 30, 2000, and every two weeks thereafter
                  (the "INTERIM FINANCING") until the earlier of (i)
                  the Closing Date or (ii) March 31, 2000. A condition
                  to each advance of Interim Financing by HSNS is the
                  provision of adequate security to HSNS, in the form
                  of HSNS Common Stock, so that the total value of
                  security held by HSNS will be at least 2.5 times the
                  total of the Prior Loan and the amount of Interim
                  Financing that will have been provided after that
                  advance, plus any accrued interest.

         Subsection 4.14(f) of the Agreement is hereby amended to read as
follows:

                  If the Closing does not occur by March 31, 2000, due
                  to termination of this Agreement or otherwise, the
                  Interim Financing shall be paid by cancellation of
                  Common Stock held as security therefor, having
                  Market Value equal to the debt being repaid. Any
                  remaining Common Stock held as security shall be
                  returned to Summus.

         Subsection 10.11(b) of the Agreement is hereby amended to read as
follows:

                  either party may terminate this Agreement if the
                  Closing does not occur by March 31, 2000;

         This Amendment may be executed in any number of counterparts, each of
which shall be deemed an original, and all of which together shall constitute
one and the same instrument.
