suit or action at law or in equity against each other in any way related to the

have raised in the Unlawful Detainer Proceedings or in any other civil action
between them prior to the date of this Agreement. ("Subject Matter of the Mutual
Covenants"). These mutual covenants not to sue may be plead and treated as a
complete defense to any action or proceeding that may be brought, instituted, or
taken by any party to this Agreement against the other party with regard to the
Subject Matter of the Mutual Covenants, and they shall forever be a complete bar
to the commencement or prosecution of any such action, litigation, arbitration,

disclose the same as needed among themselves, their counsel, accountants and
lenders and as required by any regulatory or taxing authority or the rules of
any stock exchange, and in response to lawful process. If any party is served
with legal process that may require it to testify regarding any aspect of this
Agreement or the circumstances surrounding it then that party shall immediately
tender the defense of the legal process to the other parties, allowing the other
parties to defend against the process at their own expense and, if the defense
is unsuccessful and the other party is required to testify regarding this
Agreement, or the circumstances surrounding it the defending party may at its
own expense endeavor to limit such testimony to the minimum amount of
information required to be given by law. Any breach of this provision by any
party shall subject that party to any and all damages allowed in law as well as
to equitable relief. This confidentiality provision shall not apply to any legal
process brought by any of the parties to this Agreement to enforce any of the
obligations under it.
