A rational parametrizat1on of the leading portion of the Landau manifold for the five-point function is developed. The parameters chosen are the integration parameters. If these parameters satisfy a normalization condition, then the physical-sheet singularities are found when all the signs of the real part of all the parameters are the same. (auth)
