2. The principal subject of this alliance is the defence of the Pope and the Church.
3. The Pope and King Ferdinand bind themselves to defend, with their combined forces, the states which they possess at present in Italy, against all and every aggressor, whoever he may be. The Pope promises also to use his spiritual weapons in defence of his ally.
4. The Pope promises to excommunicate any prince, republic, &c., who may attack King Ferdinand or his daughter, Queen Juana, in such of their possessions as are not situated in Italy. He likewise grants King Ferdinand and Queen Juana a tenth in all their dominions, to be employed in the defence of their states.
5. Neither of the contracting parties is at liberty to enter into negotiations with the King of France, without the consent of the other contracting party, respecting the re-occupation by the French of Milan, Genoa, Asti, &c.
6. Neither of the allies will conclude any treaty with any other prince or republic in prejudice of his ally.
7. This alliance cannot be abrogated by any other treaty which the allies, or any one of them, may hereafter conclude with other states.
8. This treaty is to be kept secret. Either of the contracting parties is at liberty to consult respecting it with three of his most confidential advisers, who, however, must swear to keep it secret.
9. Two copies of this treaty are to be made. They are to be written by Hieronymo de Vich, the ambassador of King Ferdinand. One of the copies is to be signed and sealed by the Pope, and to be sent to King Ferdinand.
