"(c) Any person who touches an intimate part of another person for
the purpose of sexual arousal, sexual gratification, or sexual abuse,
and the victim is at the time unconscious of the nature of the act
because the perpetrator fraudulently represented that the touching
served a professional purpose, is guilty of sexual battery. A
violation of this subdivision is punishable by imprisonment in a
county jail for not more than one year, and by a fine not exceeding
two thousand dollars ($2,000); or by imprisonment in the state prison
for two, three, or four years, and by a fine not exceeding ten
thousand dollars ($10,000)."
