Abstract: The correlation of the ROSAT All-Sky Survey and the Green Bank 5GHz radio survey yielded a large number of intermediate BL Lac objects, a new class of AGN which exhibits spectral energy distributions intermediate between the previously known classes of X-ray and radio-selected BL Lac objects. We report on recent ROSAT, ASCA and BeppoSAX observations of a few archetypal objects of this class. The obtained broadband X-ray spectra are crucial for our understanding of this type of objects and they provide an important test for the proposed unification scenarios of BL Lac objects.
