(c) The procedure for introducing evidence as described in subsection (b) of this Code section shall be as follows:

(1) At the time the defense seeks to introduce evidence which would be covered by subsection (b) of this Code section, the defense shall notify the court of such intent, whereupon the court shall conduct an in camera hearing to examine the accused's offer of proof;

(2) At the conclusion of the hearing, if the court finds that any of the evidence introduced at the hearing is admissible under subsection (b) of this Code section or is so highly material that it will substantially support a conclusion that the accused reasonably believed that the complaining witness consented to the conduct complained of and that justice mandates the admission of such evidence, the court shall by order state what evidence may be introduced by the defense at the trial of the case and in what manner the evidence may be introduced; and

(3) The defense may then introduce evidence pursuant to the order of the court.
