We have obtained relatively deep (exposure time 3-15m per image, limiting magnitude R=24-25) optical images for the majority of the sources in the 5 XMM-Newton fields, using EFOSC2 at the ESO 3.6m telescope, FORS1 at VLT, and DOLORES at the TNG. Optical spectra of 59 out of the 110 sources with optical counterparts brighter than R=24 were obtained using EFOSC2 at the ESO 3.6m telescope, DOLORES at the TNG and FORS1 at the VLT/UT1 during 6 observing runs performed between August 2001 and March 2004. A total of 12 nights at the 3.6m and TNG telescopes and 40 hours of VLT time were devoted to this program.
