We present 6 ASCA and SAX observations of 4 intermediate BL Lac objects(1034+5727, 1055+5644, 1424+2401, 1741+1936). Their X-ray spectral propertiesand spectral energy distributions are compared to typical X-ray and radioselected BL Lacs. 1055+5644 varied by a factor of ten in flux withoutsignificant spectral changes.
