The optical characteristics of a sample of 30 active galactic nuclei (AGN), discovered in EXOSAT CMA fields at high galactic latitude, are discussed. Optical spectra were obtained in the course of the identification work in 1988 and 1989. The data was reduced in a uniform fashion and fitted with multicomponent model spectra. Particular care was used in identifying and modeling the variety of Fe multiplets present in the wavelength band under consideration. Preliminary results of this work in terms of redshift and luminosity distributions, soft X-ray to optical luminosity ratio, and line strengths versus soft X-ray luminosity are discussed.
