  We present the first results of the hard (5-10 keV) ASCA GIS survey SHEEP
(Search for the High Energy Extragalactic Population).
  We have analysed 149 fields covering an area of 39 sq. deg detecting 69
sources. Several of these appear to be associated with QSOs and Seyfert-1
galaxies but with hard X-ray spectra, probably due to high absorption. Indeed,
the hardness ratio analysis shows that the spectra of the majority of our
sources can be represented with a ``scatterer'' model similar to obscured
Seyfert galaxies locally.
  According to this model, our sources present high intrinsic absorption
(logN_H~23) but also significant amounts of soft X-ray emission coming from
scattered light.
