Such types of weak-lined quasars (hereafter WLQs) challenge both the standard orientation-based quasar unification paradigm, and also quasar models that explicitly include factors beyond orientation (e.g., "disk+wind'' BELR models). WLQs thus represent a new extreme of parameter space. Here, we propose STIS UV observations (7 orbits) for six WLQs to measure their (weak) Lyalpha line properties and their UV continuum slopes. Our targets cover 0.910 per resolution element at 1216 Angstroms rest-frame, based on their GALEX NUV magnitudes. Target acquisition exposure times (with STIS/CCD) were calculated to achieve S/N > 40 over a 3x3 pixel checkbox, based on their SDSS optical magnitudes. We will take two exposures per orbit dithered along the slit, in order to clean for cosmic-rays and hot pixels.
