[CBS LOGO AND CBS SPORTS LETTERHEAD]

Mr. Lawrence L. Epstein
VP of Finance & CFO
15 Princess Road
Lawrenceville, N.J.  08648

Dear Larry:                                     November 5, 1998

This letter will confirm the agreement of Princeton Video Image,
Inc. ("PVI") and CBS Sports, A Division of CBS Broadcasting Inc.
("CBS") with regard to PVI providing exclusively to CBS services
using the system developed by PVI ("PVI System") for the real-time
electronic insertion of images ("Electronic Images") into live
television broadcasts of NFL football games.

PVI and CBS hereby agree as follows:

1.   Using its own proprietary hardware and software system, PVI
     will provide the insertion of Electronic Images into the CBS
     television broadcasts listed on Exhibit I attached hereto. 
     From the date hereof through the 1998 AFC Championship Game
     PVI will not provide the PVI System and services set forth
     below to any other television broadcaster for NFL football
     games.  It is initially contemplated that PVI will provide
     inserts during all such live broadcasts in up to three (3)
     camera feeds for each game and that the inserts will consist
     of an indication of the location of the first down yard
     marker.  Such inserts will include promotional material or
     advertising for CBS and others as CBS so elects.

2.   To enable PVI to provide its services, CBS will provide PVI
     reasonable advance access to all games, access to game
     television production sites and the cooperation of those
     broadcasting the games.  No persons other than PVI personnel
     shall have access to PVI Systems without PVI's written
     consent.

3.   CBS will be responsible for obtaining all rights and
     permissions ("Required Permissions") from the NFL required to
     enable PVI to provide the services contemplated hereunder. 
     This agreement is contingent upon CBS receiving approval from
     the NFL after CBS demonstrates the technology to the NFL.  CBS
     has obtained the required permissions and approval from the
     NFL to enable PVI to provide the services hereunder.



4.   CBS and PVI will mutually agree on the services to be
     provided, including image location, content and appearance of
     Electronic Images.

5.   PVI will work cooperatively with CBS to identify sponsors for
     Electronic Image advertising for use in college football game
     broadcasts.  To the extent that advertisers acceptable to CBS
     can be identified by PVI, CBS will be solely responsible for
     negotiating arrangements with such advertisers for their
     participation in Electronic Image advertising utilizing the
     PVI System.  If CBS can reach agreements with such
     advertisers, then CBS will discuss with PVI an agreement
     between PVI and CBS for the inclusion of such advertisers in
     Electronic Images for college football games.  CBS shall be
     under no obligation to use the Electronic Images in any
     college game broadcasts.

6.   In consideration for the services provided in paragraph 1 and
     for all rights granted herein, for the games listed on 
     Exhibit I, CBS will pay to PVI the total aggregate sum of 
     [CONFIDENTIAL TREATMENT REQUESTED].

7.   PVI does not warrant that PVI will be able to provide
     uninterrupted or error free services to CBS for any game
     broadcast utilizing the PVI System; provided, however, PVI
     will use its best efforts to correct the problem causing the
     error as soon as practicable.  If PVI is unable to provide the
     PVI System for any game on Exhibit I or if during any game the
     PVI System does not function properly, the total sum due
     hereunder will be reduced pro rata.

9.   PVI, at its sole cost expense, will obtain and maintain in
     force, with an insurance carrier acceptable to CBS, insurance
     coverage as follows:  (i) errors and omission insurance
     covering intellectual property having standard coverage,
     including, but not limited to, coverage with respect to
     infringement of common law or statutory copyright, patents,
     trademarks, infringement of rights in material to be broadcast
     or in the manner of presentation thereof and unauthorized use
     of material; (ii) Commercial General Liability Insurance and
     (iii) Workers Compensation Insurance.  CBS will be a named
     insured on all such policies.

10.  [CONFIDENTIAL TREATMENT REQUESTED]

11.  CBS acknowledges that it does not have nor will it gain any
     right, title or other proprietary interest in any of PVI's
     patents, patent rights, copyrights, trade names, service
     marks, trade secrets and confidential information relating to

     copyright and other intellectual property rights which are
     necessary to enter into this Agreement and provide such
     services making use of the PVI System.

14.  The rights and obligations of CBS and PVI shall be governed by
     and construed in accordance with the laws of the State of New
     York.

The parties intend that provisions customary in agreements of this
nature including but not limited to those covering warranties,
