  We present results from BeppoSAX observations of 10 low redshift quasars. The
quasars are part of the Laor et al. (1997) sample of 23 optically selected PG
quasars with redshift <0.4 and low Galactic absorption along the line of sight.
Significant spectral curvature is detected for the 6 quasars with the highest
signal to noise ratio in their low energy spectra. The average curvature can be
parameterized as a flattening of the underlying power law by Delta_alpha ~ 0.5
above ~1 keV. We find that quasars with a steeper soft X-ray (0.1-2 keV)
spectrum tend to be steeper also at higher (2-10 keV) energies. The
distribution of the best fit 2-10 keV slopes is similar to that found for other
radio-quiet AGN and characterized by a large dispersion around the mean:
alpha_E ~ 1.0+/-0.3. Iron K_alpha lines are detected in 4 quasars. In the
narrow-line quasar PG 1115+407, the rest frame line energy (6.69+/-0.11 keV)
and equivalent width (580+/-280 eV) are consistent with those found in a few
low redshift narrow-line Seyfert 1 galaxies (NLSy1). This, together with the
similarity of the 0.1-10 keV X-ray continuum, suggests that this quasar is the
higher redshift and luminosity analog of a NLSy1. In the broad line quasar PG
0947+396, the rest-frame line energy suggests fluorescence from cold iron. The
line equivalent width (> 400 eV) is however about 2-3 times higher than that
usually found in Seyfert 1 galaxies. The high energy power-law slopes and the
iron line emission properties seem to be unrelated to the X-ray luminosity.
