      and/or the content (e.g., the data calculated from the sensor, such as the
      speed of the moving object) of the insertion, where such combination is
      performed onsite;

            (2) Any Products/Services performing post production;

   DISPUTES ARISING IN CONNECTION WITH THIS AGREEMENT OR THE LICENSED PATENTS

      8.1 Subject to Article 8.2, this Agreement, and any disputes between the

respects, under the laws of the State of New York, irrespective of its choice of
law rules. Each Party agrees that it shall be subject to the exclusive personal
jurisdiction of the federal courts within the State of New York and to venue
within New York City with respect to any dispute relating to this Agreement.

nationally recognized mediation center) if any Party so requests such mediation,
for a period of ninety (90) days prior to initiating any litigation. The
mediation shall occur over the telephone or the Internet or physically within
New York City, NY. Any fees and expenses relating to any mediation so requested
by any Party shall be shared equally by the Parties engaged in the dispute. Any
delay by a Party in initiating litigation in accordance with this provision
(including any delay beyond 90 days to the extent agreed by the disputing
Parties) shall be without prejudice to any Party's ability to obtain specific
performance, injunctive or any other equitable relief in connection with such
dispute.

      8.3 Each Party shall have the right to audit another Party's compliance
with license limitations imposed by this Agreement. Such audit shall be
performed by an independent third party selected by the Party requesting the
audit at reasonable times and with reasonable notice, but no more frequently
than once in any six month period. The independent third party shall only
investigate a Party's compliance with this Agreement and notify the
investigating party with only the nature of any non-compliance, but shall not
share any confidential proprietary information of the investigated party with
the investigating party.

                                    ARTICLE 9
                            MISCELLANEOUS PROVISIONS

      9.1 No Party is under any obligation to mark Products/Services that may
potentially fall within the scope of the Agreement with patent numbers or with
indications of patents pending, but a Party may do so, in its sole discretion,
as it deems practical.

      9.2 None of the Parties can use another Party's name or trademarks without
the express prior written consent of that Party.

      9.3 Any Party hereto may assign any of its rights hereunder to any of its
Affiliates, provided that such Affiliate is not a Competitor of the Other Party,
and such assignment shall be terminated if the Affiliate becomes a Competitor of
the Other Party. Other than as stated in the first sentence of this Article 9.3,
PVI may not assign any of its rights or delegate any of its duties under this
Agreement without the prior written consent of Sportvision, which consent shall
not be unreasonably withheld or delayed. Other than as provided in the first
sentence of this Article 9.3, neither Sportvision nor Fox may assign any of
their respective rights or delegate any of their respective duties under this
Agreement without the prior written consent of PVI, which consent shall not be
unreasonably withheld. It shall be reasonable for either Party to withhold
consent if a Party attempts to assign its rights or delegates its duties under
this Agreement to a Competitor of the Other Party. Sportvision and Fox hereby
consent to any assignment of PVI's rights or delegation of PVI's duties under
this Agreement to Cablevision Systems Corporation, Presencia en Medios, S.A. de
C.V. or any of their respective Affiliates. PVI hereby consents to any

assignment of Sportvision's rights or delegation of Sportvision's duties under
this Agreement to Fox or Motorola or any of their respective Affiliates.

      9.4 The Parties shall be considered to be independent contractors of each
other. No Party undertakes by this Agreement or otherwise to perform any of the
obligations of any other Party. In no way is any Party to be construed as an
agent, or acting as an agent, of any other Party in any respect. In no way is
this Agreement to be construed as creating a joint venture, partnership or agent
relationship between any of the Parties.

      9.6 This Agreement and the Settlement Documents contain the entire and
only agreements between the Parties as to the subject matter of such agreements
and supersede all preexisting agreements between them respecting such subject
matter.

      9.7 The provisions of this Agreement are severable, and in the event that
any one or more provisions, or any portion thereof, are deemed illegal or
unenforceable under applicable law by a court of competent jurisdiction, that
provision(s) or portion thereof shall be ineffective to the extent of such
invalidity or unenforceability only, and the remaining provisions or portion
thereof, as the case may be, shall remain in full force and effect unless the
deletion of such provision(s) or portion thereof shall cause this Agreement to
become materially adverse to any Party, in which event the Parties shall use
reasonable efforts to arrive at an accommodation that best preserves for the
Parties the benefits and obligations of the offending provision(s) or portion
thereof.

      IN WITNESS WHEREOF, the Parties have caused this Agreement to be executed
by their duly authorized officers on the respective dates hereinafter set forth.
