- There shall be unrestricted technology exchanges between all the parties
- The Klingons and the Romulans shall jointly attack the Federation
The Klingon Defense Force acquired cloaking devices, while Romulans acquired new-generation warp cores, as well as starships. (TOS: "The Enterprise Incident", Star Trek III: The Search for Spock, Star Trek IV: The Voyage Home)
As part of the Treaty, the Romulan Guard received Klingon-built hulls but at an exorbitant cost. One of the Treaty's provisions was never fulfilled, that is, the delivery of a QeylIS BetleH-class battleship to the Romulan Guard. (Star Fleet Battles)
This treaty was simply there to explain why the Klingons had cloaking devices by 2285.
