(2) Upon agreement by both parties, additional documentary evidence may be presented at the hearing. The parties shall arrive at the hearing location or make documents available in sufficient time before the time scheduled for the hearing for the purpose of exchanging exhibits to be introduced. When documents are to be offered into evidence at the hearing, the one offering the exhibit shall provide a minimum of ten copies.

(3) If the parties do not reach an agreement on the submission of additional documentary evidence, at the commencement of the hearing the presiding officer shall, after hearing argument, rule on the admissibility of the documents.
