  We have obtained medium-resolution spectra of seven UV-bright stars
discovered on images of four southern globular clusters obtained with the
Ultraviolet Imaging Telescope (UIT). Effective temperatures, surface gravities
and helium abundances are derived from LTE and non-LTE model atmosphere fits.
Three of the stars have sdO spectra, including M4-Y453 (Teff = 58800 K, log g =
5.15), NGC 6723-III60 (Teff = 40600 K, log g = 4.46) and NGC 6752-B2004 (Teff =
37000 K, log g = 5.25). All seven stars lie along either post-extended
horizontal branch (EHB) or post-early AGB evolutionary tracks. The post-early
AGB stars show solar helium abundances, while the post-EHB stars are helium
deficient, similar to their EHB progenitors.
