             the last 8 months

          -  Previous treatment with any facial aesthetic procedure (e.g. injection with fillers,
             chemical peeling, photo rejuvenation) in the glabellar area within the last 12 months

          -  Previous insertion of permanent material in the glabellar area

          -  Planned treatment with botulinum toxin of any serotype in any other body region during
             the study period

          -  Any surgery in the glabellar area including surgical removal of the corrugator,
             procerus, or depressor supercilii muscles or a combination of these, or scars in the
             glabellar area and the surrounding areas (including eye brow)

          -  Energy based or cryo-therapy based treatment of facial muscles superior to the lateral
             canthus

          -  Any other planned facial aesthetic procedure during the trial period, superior to the
             level of the lateral canthus (subjects can continue with their usual skin care
             routine)

          -  Inability to substantially lessen glabellar frown lines even by physically spreading
             them apart

          -  Marked facial asymmetry

          -  Ptosis of eyelid and/or eyebrow, or history of eyelid and/or eyebrow ptosis

          -  Evidence of recent alcohol or drug abuse

          -  Medical or psychiatric conditions that may increase the risk associated with study
             participation or may interfere with the interpretation of study results and, in the
             judgment of the Investigator, would make the subject inappropriate for entry into this
             study
