DOIAbstract
The HERMES experiment has extensively studied exclusive meson production in deep-inelastic scattering of the 27.6 GeVelectron/positron beam of HERA by various gaseous targets internal to the storage ring. Recent results on exclusive omegaproduction are presented: spin-density matrix elements using unpolarized and longitudinally polarized leptons andunpolarized hydrogen and deuterium targets, and azimuthal distributions for scattering from transversely polarizedprotons. In addition, an analysis of ratios of helicity-amplitudes for exclusive production of rho mesons fromtransversely polarized protons is presented
