and unconditionally releases, acquits and forever discharges the other

not now known to any of the parties hereto which may later develop or

not known at the time of executing a release, including California
Civil Code Section 1542 and similar provisions under other state laws;

          "A general release does not extend to claims which the
           creditor does not know or suspect to exist in his favor at
           the time of executing the release, which if known by him
           must have materially affected his settlement with the debtor."

hereafter discover facts in addition to or different from those which
the Parties now know or believe to be true with respect to the subject
matter released hereby but that it is the Parties' intention hereby to

and differences, now known and unknown, foreseen and unforeseen,
suspected or unsuspected, as provided herein.

3.  Non-Admission of Liability.

     All claims, past, present or future, are disputed and this full
and final settlement thereof is neither to be construed or deemed as
evidence of liability, culpability, negligence, or wrongdoing on the
part of the Parties or to any other third party claimant, nor as an
admission of liability or responsibility at any time or in any manner
whatsoever. This Agreement is a settlement document and shall be
inadmissible as evidence in any proceeding, except an action or
proceeding to approve, interpret or enforce this Agreement.

filed any complaints or charges or lawsuits against the other, nor
with any governmental agency or any court.  In addition, each of the

Parties in connection with this matter.  The Parties shall hold each
other harmless and indemnify the other from any claims or actions,

representation, or warranty, express or implied, not contained herein,
concerning the subject matter of this Agreement to induce the Parties
to execute this Agreement; and that this Agreement was not executed in
reliance on any such promise, representation, or warranty.
