We have obtained medium-resolution spectra of seven UV-bright stars di
scovered on images of four southern globular clusters obtained with th
e Ultraviolet Imaging Telescope (UIT). Effective temperatures, surface
gravities and helium abundances are derived from LTE and non-LTE mode
l atmosphere fits. Three of the stars have sdO spectra, including M4-Y
453 (T-eff = 58800 K, log g = 5.15), NGC 6723-III60 (T-eff = 40600 K,
log g = 4.46) and NGC 6752-B2004 (T-eff = 37000 K, log g = 5.25). All
seven stars lie along either post-extended horizontal branch (EHB) or
post-early AGE evolutionary tracks. The post-early AGE stars show sola
r helium abundances, while the post-EHB stars are helium deficient, si
milar to their EHB progenitors.
