         6. Current License Fees. The Parties agree that it is critical to ACIS
that this License Agreement not be available as a vehicle to exploit the value
of the Kernel without negotiating directly with ACIS. The Parties also agree
that it is critical to VSI to have a set license fee for the applications which
it has and which it plans to develop. If the ACIS Kernel is implemented on the
foundation of the Microsoft Windows NT platform or any successor platform
released through the year 2002, ACIS agrees that its license fees to VSI shall
be fixed as follows below under License Fees. If the Microsoft Windows NT
platform is replaced by a different underlying platform after the year 2002,
ACIS shall determine the appropriate ACIS Server Kernel license fees for such
alternate platform and grant VSI best pricing on said license fees.

                                  LICENSE FEES

VSI Agrees to pay a one-time license fee to ACIS of $20.00 for each installed
copy of each product or application that includes or uses (a) the VSI Licensed
Kernel outside the Video Conferencing Field or (b) the ACIS Server Kernel that
is sold by, or on account of, VSI. [Beginning January 1, 2000, and continuing
January 1 of each year thereafter, the foregoing royalty shall be adjusted by a
percentage equal to the percentage change in the U.S. Consumer Price Index for
the twelve month period ending on November of the preceding year.]

         7. Intellectual Property Rights. VSI agrees to release, and hereby
unconditionally releases, now and in the future, any and all claims of right or
ownership in and to ACIS Software. ACIS agrees to release, and hereby
unconditionally releases, any and all claims of right or ownership in and to VSI
patents on the Omega operating system, to VSI patents on VSI's video
conferencing system, and to VSI patents on VSI's new Voyager development. The
parties contemplate that VSI will code one or more parts of the ACIS Software.
VSI agrees that any ACIS Software shall be a "work made for hire." and that ACIS
shall own all the copyright rights in such work. IF AND TO THE EXTENT ANY SUCH
MATERIAL DOES NOT SATISFY THE LEGAL REQUIREMENTS TO CONSTITUTE A WORK MADE FOR
HIRE, VSI HEREBY ASSIGNS ALL ITS COPYRIGHT RIGHTS AND OTHER INTELLECTUAL
PROPERTY RIGHTS IN THE WORK TO ACIS.

         8. Modifications or Enhancements. ACIS grants VSI the right to modify,
improve or enhance ACIS Software, and agrees that any change shall not modify
the Grant of License as provided herein.

         9. Covenant Against Exceeding Scope of License. VSI is specifically
granted the right to use the ACIS Software pursuant to this license, but VSI
agrees that any use outside the scope of this license is prohibited, without
prior written agreement by ACIS, Inc.

         10. Patent Notice. VSI agrees to label all of its products as "Patent
Pending, ACIS, Inc., 1999," until the patent is granted, and thereafter label

(such date of grant being defined as the

                                       2
<PAGE>   3
"Patent Date") by the U.S. Patent and Trademark Office on all or any portion of
the claims contained in the Patent Application. If an Exchange Date is not
established by VSI, the Exchange Date shall be the 180th day following the
Patent date. The Exchange Date shall be established by a letter in writing from
VSI to the President of ACIS at the address set forth in the first paragraph of
this Agreement. In the event of a stock split, reverse stock split, stock
dividend or other reclassification or other action that has the effect of
changing all of the outstanding shares of a party into a smaller or larger
number during the pendency of this provision, the number of shares subject to
the Share Exchange shall be adjusted pro-rata. Should ACIS receive an offer to
purchase the patent rights in the Kernel or any other right in or to the
intellectual property relating or pertaining to the Kernel (in either case a
"Sale Transaction"), prior to the exchange, the Share Exchange shall be
accelerated to be consummated on the day immediately prior to the date of the
sale of the patent rights. ACIS shall give VSI written notice of a Sale
Transaction at least twenty (20) days prior to the closing thereof. VSI agrees
