Rogina in the United States District Court, Middle District of Florida, Orlando
Division, Case No. 99-513-CIV-ORL-19A for breach of the Employment Agreement and

Myung K. Kim, Bradford Richdale and Richard Seifert, who, at various times were,
or still are, officers, directors or shareholders of HSNS.

         E.       The Parties desire to settle the Lawsuit and any and all other
claims, causes of action or rights that any of the parties may have against one
another.

                              TERMS AND CONDITIONS

         For the mutual promises, representations, covenants and agreements, and
on the conditions set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Parties respectfully represent, covenant and agree as follows:

         3.       SUMMUS guarantees payment to Mr. Rogina of all monies due
under this Agreement, and SUMMUS represents and warrants that it has sufficient
funds to pay the guaranteed amount upon HSNS' default.

         4.       If HSNS fails to pay to Mr. Rogina any monies due and owing
under this Agreement, an ex parte judgment for the accelerated balance will be
entered against HSNS and SUMMUS without further hearing or action by the Court.
SUMMUS hereby consents to the jurisdiction of the United States District Court,

         7.       Upon execution of this Agreement by HSNS, HSNS' claims against
Mr. Rogina shall be released and waived. Until HSNS has performed all of its
obligations under this Agreement, HSNS shall hold the Lawsuit in abeyance. At

Rogina or the escrow agent, HSNS shall dismiss the Lawsuit with prejudice. Mr.
Rogina's right to pursue a counter-claim and third party claim against HSNS, Mr.
Cimino, Mr. Richdale and Mr. Seifert shall not be waived until HSNS has

in whole or on part on or after July 1, 2000, and within five (5) years from the
date hereof, at the same strike price as set forth in the Employment Agreement.

shall provide all documentation and evidence of the number of anti-diluted
shares that Mr. Rogina is entitled to under this Agreement. HSNS shall reserve
shares for issuance upon exercise of the option. Within five (5) days after HSNS

deliver the shares to Mr. Rogina and/or his designee.
