  We present preliminary results from a study with XMM-Newton of the galactic
serendipitous sources in a sample of 28 nearby Seyfert galaxies (with D < 22
Mpc). We concentrate here on a subset of four galaxies, namely: NGC3185,
NGC3486, NGC3941, and NGC4565. In these galaxies we found six ultraluminous
X-ray source (ULX). The large collecting area of XMM-Newton makes the
statistics sufficient to perform spectral fitting with simple models. We
shortly discuss the results obtained so far.
