"Moreover, since the rebellion and usurpation of Urbino have occurred during the above-mentioned misunderstandings, all the confederates aforesaid and each of them shall bind themselves to unite all their forces for the recovery of the estates aforesaid and of such other places as have revolted and been usurped.
"His Excellency the Duke of Romagna shall undertake to continue to the Orsini and Vitelli their ancient engagements in the way of military service and on the same conditions.
"His Excellency promises further not to insist on the service in person of more than one of them, as they may choose: the service that the others may render shall be voluntary.
"He also promises that the second treaty shall be ratified by the sovereign pontiff, who shall not compel Cardinal Orsino to reside in Rome longer than shall seem convenient to this prelate.
"Furthermore, since there are certain differences between the Pope and the lord Gian Bentivoglio, the confederates aforesaid agree that they shall be put to the arbitration of Cardinal Orsino, of His Excellency the Duke of Romagna, and of the lord Pandolfo Petrucci, without appeal.
"Thus the confederates engage, each and all, so soon as they may be required by the Duke of Romagna, to put into his hands as a hostage one of the legitimate sons of each of them, in that place and at that time which he may be pleased to indicate.
"The same confederates promising moreover, all and each, that if any project directed against any one of them come to their knowledge, to give warning thereof, and all to prevent such project reciprocally.
"It is agreed, over and above, between the Duke of Romagna and the confederates aforesaid, to regard as a common enemy any who shall fail to keep the present stipulations, and to unite in the destruction of any States not conforming thereto.
