recognize that the Representative Allocation is a media buy with respect to
Advertising Services in the United States and that the Advertising Services to
be provided to the Company in the Territory will differ, but the Parties also

in the Territory will be based upon a similar nature, volume, placement, amount
and other factors that were relevant to the creation of the Representative

assets differ significantly from their domestic assets, and that the allocation
of Advertising Services must be adjusted accordingly. The Parties shall meet

Company for the season beginning in September of such year. The Parties intend

         2.2      Determination of Dollar Amount of Advertising Services.
The News Parties agree that the dollar amount of Advertising Services to be
provided to the Company pursuant to this Agreement shall be based upon
advertising prices which are charged by the News Parties to similarly situated
parties based upon similar volume placement, amount and other factors relevant
to the pricing of advertising services, but in no event shall the dollar amount
charged for Advertising Services to be provided to the Company

                                        2
