         Re:  "World Poker Tour" -- Amendment Number 4 to Season 2 Agreement
              [(Contract #:  WPT002/COP/TRV/PL/SC/CG)]


Dear Ladies and Gentlemen:

         Reference is made to (i) that certain master agreement (the "Master
Agreement") dated as of August 22, 2003 between WORLD POKER TOUR, LLC
("Producer") and THE TRAVEL CHANNEL, L.L.C. ("TRV"); (ii) that certain agreement
attached to the Master Agreement (the "Attachment"), dated as of August 22, 2003
between Producer and TRV in connection with the second season of the television
production currently known as the "World Poker Tour" (the "Program"); (iii) that
certain fully executed Amendment Number 2 to Season 2 Agreement (the "First
Amendment"), dated as of April 22, 2004; (iv) that certain fully executed
Amendment Number 2 to Season 2 Agreement (the "Second Amendment"), dated as of
May 10, 2004; and (v) that certain fully executed Amendment Number 3 to Season 2
Agreement (the "Second Amendment"), dated as of June 23, 2004. The Master
Agreement and the Attachment, as amended by the First Amendment, the Second
Amendment and the Third Amendment, are collectively hereinafter referred to as
the "Agreement".

         Except as otherwise defined herein, capitalized terms used but not
defined herein shall have the meaning set forth in the Agreement. The parties
hereby agree that the Agreement shall be supplemented and amended as follows:

         1. TITLE SPONSORSHIP FOR THE WPT SERIES ON TRV

         A. With regards to Season 3 of the Program, in all categories other
than ** , any title sponsorship sale for Season 3 (containing tournaments being
held in 2004-2005), shall include a flat media buy of $ ** on the Travel
Channel. For that amount, currently the title sponsor will receive ** (**) units
in each regular season episodes (up to a maximum of 17 regular season episodes).

         B. With regards to Season 3 of the Program, the title sponsorship from
a ** sponsor will require a flat media buy of $ ** on the Travel Channel. For
that amount, currently the title sponsor will receive ** (**) units in each
regular session episode (up to a maximum of 17 regular season episodes).

         C. Inclusion of the Title Sponsor in any WPT special episodes (i.e.
episodes other than the regular season tour stops) and the media buy component
of that inclusion will be negotiated in good faith between WPT and the TRV ad
sales department.

         D. The terms and conditions for inclusion of the Title Sponsor beyond
the initial seventeen (17) episodes of the Program and the media buy component
of that inclusion will be worked out in good faith between WPT and the TRV ad
sales department.

         E. In subsequent seasons (after Season 3), the applicable media buy
number above will increase as outlined in the Agreement by $ ** each subsequent
season that the entitlement sponsorship is sold. In addition, as outlined in the
Agreement, TRV will receive **% of the increase in the Adjusted Gross Revenues
received by WPT for the title sponsorship rights from the last season that the
title sponsorship rights were sold. The number of units is subject to change,
but TRV acknowledges and agrees that the terms of this Title Sponsorship media
buy were not developed and will not be developed in such a way to intentionally
increase the cost of units available to the title sponsor vis a vis other
purchasers of units in the same categories in the show as the title sponsor.

         2. **
