647. Every person who commits any of the following acts is guilty of disorderly conduct, a misdemeanor:

(a) Who solicits anyone to engage in or who engages in lewd or dissolute conduct in any public place or in any place open to the public or exposed to public view.

(b) Who solicits or who agrees to engage in or who engages in any act of prostitution. A person agrees to engage in an act of prostitution when, with specific intent to so engage, he or she manifests an acceptance of an offer or solicitation to so engage, regardless of whether the offer or solicitation was made by a person who also possessed the specific intent to engage in prostitution. No agreement to engage in an act of prostitution shall constitute a violation of this subdivision unless some act, in addition to the agreement, is done within this state in furtherance of the commission of an act of prostitution by the person agreeing to engage in that act.
