                PROPOSED TERMS OF SETTLEMENT OF THE GTE LAWSUIT


1.     In consideration of the agreement of IT Network to make the payments
       provided for in clause 2 below, Cableshare shall confer upon IT Network
       a license of the Cableshare Intellectual Property to enable IT Network
       to act as sublicensor of such property in executing a patent license
       agreement (the "Patent License Agreement") with GTE ("GTE Main Street")
       on the terms annexed hereto as Schedule "A" and thereby confer on GTE
       Main Street the rights to Cableshare Intellectual Property to be
       conferred on GTE Main Street pursuant to the terms thereof.  The license
       of the Cableshare Intellectual Property in favor of IT Network
       hereinbefore provided shall be solely for the purpose of executing the
       Patent License Agreement and shall not confer upon ITN any additional
       right to use or to license other persons to use Cableshare Intellectual
       Property.  (Notwithstanding anything herein otherwise contained, nothing
       herein shall derogate from ITN's rights under the agreement to which
       this Attachment is attached or under any other agreement between
       Cableshare (either individually or collectively) on the one part and IT
       Network on the other.)

2.     In return for Cableshare's grant of license provided in clause 1 above,
       IT Network shall agree to pay Cableshare (forthwith upon IT Network's
       receipt thereof) all amounts paid to ITN by GTE Main Street pursuant to
       clauses 2 and 3 of the Patent License Agreement.

3.     IT  Network agrees that at Cableshare's request and expense, IT Network
       will enforce all and any rights it may have against GTE Main Street
       under the Patent License Agreement.

4.     ITN and Cableshare shall forthwith upon execution of the Patent License
       Agreement by the parties thereto, do all things and execute all
       documents as may be necessary or desirable to dismiss the GTE Lawsuit.
