La Bureba
The king, who was at the time preparing for the Treaty of Torrellas, from which Diego Lopez was excluded, promised the infante John that he would receive Biscay after all and that Juan Núñez II de Lara would get La Bureba. He further stated that both could divvy up the territories currently belonging to Diego Lopez in La Rioja if the two could resolve the diplomatic crisis that was ongoing with Aragon.
