C. Except pursuant to subsection B, paragraph 2, 3, 4 or 5 of this section, a mediator is not subject to service of process or a subpoena to produce evidence or to testify regarding any evidence or occurrence relating to the mediation proceedings.  Evidence that exists independently of the mediation even if the evidence is used in connection with the mediation is subject to service of process or subpoena.

Notwithstanding subsection B of this section, when necessary to enforce or obtain approval of an agreement that is reached by the parties in a mediation, the terms of an agreement that is evidenced by a record that is signed by the parties are not confidential. The agreement may be introduced in any proceeding to obtain court approval of the agreement, where required by law, or to enforce the agreement.  If a party requests that all or a portion of the agreement remain confidential, the agreement may be disclosed to the court under seal with a request to issue appropriate orders to protect the confidentiality of the agreement, as permitted by law.
