                       ACTV, Inc. and Fox Sports Southwest

                    to Enhancement License Agreement between
                       ACTV, Inc. and Fox Sports Southwest


Licensor agrees that it will make available to ACTV for Enhancement and
inclusion in the Enhanced Regional Package all of Licensor's RSN Programming-,
limited only by applicable Rights Restrictions. If for any year during the
License Term ACTV nevertheless is unable, for lack of sufficient rights to such
events, to Enhance and Distribute at least 100 professional events out of
Licensor's RSN Programming- to substantially all of the State of Texas, unless
such number of professional events is not available in any year due to a strike,
lockout or similar league or team labor problem, the monthly License Fees for
such year shall be adjusted to the product of $[XXXXXXX] (or such greater amount
as may be specified under Section 7 of this License Agreement) multiplied by the
Number of Subscribers for the month for which payment is being computed.
Notwithstanding that there is a reduction in the geographic area within the
State of Texas to which Licensor is permitted to distribute NHL Dallas Stars
events due to another NHL team being, awarded a franchise in the Territory, all
Stars games included in Licensor's RSN Programming will nonetheless be counted
toward the 100 professional events.

                    to Enhancement License Agreement between
                       ACTV, Inc. and Fox Sports Southwest


Commencing with the 1998 NCAA football season, ACTV agrees to Enhance and
distribute, each week during the NCAA football season, as part of the Enhanced
Regional Package at least one Big VII regular season football game carried as
part of Licensor's RSN Programming. So long as it can do so without incurring
any material out-of-pocket expenses, Licensor will use commercially reasonable
efforts to assist ACTV in obtaining the rights to distribute those Enhanced
football games in areas within the United States outside of the Territory, so
long as ACTV has obtained the right to distribute the Basic Regional Service of
all Affiliated RSNs whose Basic Regional Service territories cover that area. In
addition, if at any time during the License Term Licensor requests that ACTV
Enhance and Distribute as part of the Enhanced Regional Package any other of
Licensor's RSN Programming (i.e., Licensor's RSN Programming that ACTV otherwise
is not required to Enhance under this Agreement), ACTV agrees to give such
request serious consideration and to negotiate in good faith with Licensor
regarding such request.
