On behalf of the IBIS Core Programme AGN and survey teams we report that the
following sources in the forthcoming second IBIS/ISGRI catalogue (Bird et al. 2005
to be submitted to Ap.J.) are likely to be Active Galactic Nuclei (AGN):

All sources except 4U1344-60 have a radio counterpart (either NVSS or SUMSS as in the
table above) and are also 2 MASS extended sources classified as galaxies.
IGR J10404-4625 and LEDA 170194 are emission line galaxies at redshift 0.0239 and
0.0367 respectively, although they have not yet been optically classified.
Except for LEDA 170194, all are X-ray emitting objects; the bright source
4U1344-60 has recently been detected by XMM and suggested to be a low galactic latitude,
low redshift active galaxy (Michel et al.2004, ASP Conf. Series 314, 570).
Optical follow-up is required for these sources to provide final confirmation of their nature,
but on the basis of the above characteristics they can already be tentatively classified
as AGN.
