  We present a pilot study of the X-ray properties of intermediate-mass
(~10^5-10^6 M_sun) black holes in active galaxies using the Chandra X-ray
telescope. Eight of the 10 active galaxies are detected with a significance of
at least 3 sigma, with X-ray luminosities in the range L_(0.5-2 keV) ~
10^41-10^43 ergs/s. The optical-to-X-ray flux ratios are consistent with
expectations, given the known correlations between alpha_ox and ultraviolet
luminosity, while a couple of objects appear to be anomalously X-ray weak. The
range of 0.5--2 keV photon indices we measure, 1 < Gamma_s < 2.7, is entirely
consistent with values found in samples of more luminous sources with more
massive black holes. Black hole mass evidently is not a primary driver of soft
X-ray spectral index. On the other hand, we do find evidence for a correlation
between X-ray power-law slope and both X-ray luminosity and Eddington ratio,
which may suggest that X-ray emission mechanisms weaken at high Eddington
ratio. Such a weakening may explain the X-ray weakness of one of our most
optically luminous objects.
