order of priority. Unless otherwise agreed, the parties shall each bear all of

confidential nature of all papers submitted, all negotiations, mediation
sessions, and arbitration proceedings, if any, held pursuant to this ADR
process.

                    initiate this ADR process, the parties shall negotiate for a

                    be as mutually agreed in consultation with JAMS.
