  We have observed a radio-quiet QSO Kaz 102 (z=0.136) with ASCA as a part of
our program of complete spectral characterization of hard X-ray selected AGNs.
We found that Kaz 102 shows unusual spectral properties. A simple power-law
with absorption in our galaxy gave a satisfactory description of the spectrum.
However, it showed a very hard photon index of Gamma=1.0 with no sign of deep
absorption or a prominent spectral feature. We further explored the Compton
reflection with Fe K-alpha line and warm absorber models for hardening the
spectrum. Both gave statistically satisfactory fits. However, the Compton
reflection model requires a very low metal abundance (0.03-0.07 in solar
units).The warm absorber model with no direct component is preferred and gave a
very high ionization parameter xi=200. If this is the case, the values of xi,
warm absorber column density, and variability over about 10 years may suggest
that the warm absorber resides in the broad-line region and crosses the line of
sight to the central X-ray source.
