Nevertheless, the Peloponnesians felt that the first compact with Tissaphernes, which had been concluded between him and Chalcideus, was defective and not so much to their interest as to his, and so they drew up another while Therimenes was there. And its terms were as follows:

Whatsoever territory and cities belong to King Darius or belonged to his father or their ancestors, against these shall neither the Lacedaemonians nor their allies go either for war or to do any harm; nor shall either the Lacedaemonians or their allies exact tribute from these cities. Nor shall King Darius or those over whom the King rules go against the Lacedaemonians or their allies for war or to do any harm. "2. If the Lacedaemonians or their allies have need of anything from the King or the King from the Lacedaemonians or their allies, whatever they shall persuade one another to do, this shall be right for them to do.
