The tax on each bushel (mozo) of grain, of the weight used in Constantinople, was set at one hyperpyron.[18] Süleyman's ships would not be allowed to leave the Dardanelles without permission from the Byzantine emperor and the Christian league.[18] All Byzantine prisoners held by Süleyman or any of his subordinate lords were to be released.[19] All Genoese prisoners held by Süleyman or any of his subordinate lords were to be released.[20] If a Genoese slave were to escape to Ottoman territory, he would be returned. Any Muslim held by the Genoese after Timur's attack would be released.[20] Twenty-five prisoners from Chios (a Genoese colony) held by the Ottomans were to be released.[20] The Genoese colonies in the Black Sea were relieved of the tribute to the Ottomans.[20] The tribute of 500 ducats paid until then by Chios to the Ottoman governor at Alto Luogo (Ayasoluk) would cease.[20] All territories, forts, dwellings, and anything else taken from the Venetians was to be restored to them, and Athens to return to their rule.[20] The latter provision was never actually enforced, and Antonio I Acciaioli retained control of Athens.[21][22] The Venetians received a strip of land, five miles wide, on the Greek mainland opposite the whole length of the island of Euboea (a Venetian possession), but the Ottomans were to retain the salt flats and ports in the area. The Venetians also undertook to punish anyone taking grain from Ottoman territory without paying customs duties.[20] Süleyman agreed not to increase the tribute levied on the Marquisate of Bodonitsa from what it was under Bayezid, although the marquis had conspired against the Ottomans in Thessaly.[20][7] Slaves from both sides seeking to escape in the territory of the other would be returned.[20] The tribute of 200 ducats paid until then by Naxos would cease.[20] Süleyman would return 500 Venetian prisoners, provided the Venetians released all Ottoman prisoners they held.[20] The tribute of 500 ducats paid until then by New Phocaea (a Genoese colony) would cease.[20] The transfer of the County of Salona to the Knights Hospitaller by the Despot of the Morea, Theodore I Palaiologos, was ratified.[20][23]
