We show that an intracavity optical device which utilises concurrent $\\chi^{(2)}$ nonlinearities can produce output beams which exhibit strong tripartite entanglement. Above threshold a significant degree of entanglement is predicted for beams with macroscopic intensities. We also demonstrate two independent ways that the system can exhibit a three mode form of the Einstein-Podolsky-Rosen paradox.
