We present spectra taken with the Low Resolution Imaging Spectrograph on the Keck 10m telescope of spatially-resolved structures ('fuzz') around the high-redshift radio-loud quasars PKS 0445+097 (z=2.108) and PKS 2338+042 (z=2.589). For PKS 0445+097 we oriented the slit such that it passed through the quasar nucleus and through an object identified on an HST exposure 1.8'' to the southeast of the nucleus. We find that this object has strong [OII]λ3727 emission and weaker emission due to [NeV]λ3426 and [NeIII]λ3869, at a redshift of z=0.8384. This redshift is very close ({DELTA}v=200km/s) to that of a MgII absorption line identified in the spectrum of PKS 0445+097. The line ratios and narrowness of the lines indicate that this galaxy probably has a Seyfert 2 nucleus. Moreover, we find that there is faint extended HeIIλ1640 and CIII]λ1909 from the quasar host galaxy. Both of the lines are broad (FWHM_HeII=1000±200km/s and FWHM=2200±600km/s). The limits on the fluxes, the large line widths, and the line ratio HeII/CIII] are similar to that observed for high redshift radio galaxies. From the spectrum of PKS 2338+042, we find extended Lyα emission on scales about 10'' which is strongly one sided (on the side of the stronger, closer to the nucleus, more distorted radio lobe). The extended Lyα line is broad with widths of over 1000km/s. The extended emission shows no evidence for a strong velocity shear. We also find weak extended CIV and HeII emission which has similar characteristics (line widths, line fluxes, and line ratios) to that of high redshift radio galaxies. In addition, we serendipitously discovered what appears to be a Lyα emitting galaxy about 29'' to the southeast of the quasar at z=2.665. The single line identified in the spectrum has a measure equivalent width of 2100Å and a full width at half maximum of 2150 km.s^–1. The high equivalent width and large velocity width of the putative Lyα line suggest that this galaxy must be a high redshift AGN, although we note that the upper limits on the CIV and HeII line ratios are mildly inconsistent with this galaxy harboring an AGN. An approximate calculation shows the quasar nucleus is not exciting the Lyα emission from this galaxy.
