In the event of a territorial and political rearrangement of the areas belonging to the Polish state the spheres of influence of Germany and the U.S.S.R. shall be bounded approximately by the line of the rivers Narew, Vistula, and San. The question of whether the interests of both parties make desirable the maintenance of an independent Polish state and how such a state should be bounded can only be definitely determined in the course of further political developments. In any event both Governments will resolve this question by means of a friendly agreement.
