this Agreement to be performed or complied with by the other party.

      5.    RELEASE BY LENDER.

            A.    RELEASE.  If and only if the Closing occurs, upon the
Closing, Lender, on its own behalf and on behalf of its employees,
officers, shareholders, directors, agents, successors, assigns, partners,
attorneys, agents, servants, parent, subsidiary and affiliate corporations,
hereby absolutely and irrevocably releases Borrower, and each of Borrower's
beneficiaries and certificate holders and each of their respective
trustees, partners, attorneys, officers, directors, representatives,
agents, servants, contractors, employees, parent, subsidiary and affiliate
corporations and predecessors-in-interest, and each of their respective
past and present partners, successors, heirs and assigns, and each of them
(collectively, the "Borrower Released Parties") from any and all claims,
rights, demands, suits, causes of actions, losses, costs, obligations,
liabilities and expenses (collectively, "Claims") of every kind or nature,
known or unknown, suspected or unsuspected, fixed or contingent, arising
out of or relating to any statements, representations, acts or omissions,
intentional, willful, negligent or innocent, by any of the Borrower
Released Parties in any way connected with, relating to or affecting,
directly or indirectly, the Loan, the Loan Documents or the relationship
between Lender and Borrower.

            B.    NON-RELIANCE.  Lender hereby acknowledges that it has not
relied upon any representation of any kind made by Borrower or any of the
Borrower Released Parties in making the foregoing release.

            C.    CIVIL CODE.  Lender is aware of the provisions of
Section 1542 of the California Civil Code, which Section reads as follows:

      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.

Lender waives the provisions of said Section 1542 of the California Civil
Code and the provisions of any other applicable laws restricting the
release of claims which the releasing parties do not know or suspect to
exist at the time of release, which, if known, would have materially
affected the decision of Lender to agree to this Agreement.

            D.    NO ADMISSION OF LIABILITY.  It is hereby further
understood and agreed that the acceptance of delivery of this Agreement by
the parties released hereby shall not be deemed or construed as an
admission of liability of any nature whatsoever arising from or related to
the subject of this Agreement.

      6.    RELEASE BY BORROWER.

            A.    RELEASE.  If and only if the Closing occurs, upon the

officers, shareholders, directors, agents, successors, assigns, partners,
attorneys, agents, servants, parent, subsidiary and affiliate corporations,
hereby absolutely and irrevocably releases Lender, and each of Lender's
beneficiaries, shareholders, partners, attorneys, officers, directors,
representatives, agents, servants, contractors, employees, parent,
subsidiary and affiliate corporations and predecessors-in-interest, and
each of their respective past and present partners, successors, heirs and

assigns, and each of them (collectively, the "Lender Released Parties")
from any and all Claims of every kind or nature, known or unknown,
suspected or unsuspected, fixed or contingent, arising out of or relating
to any statements, representations, acts or omissions, intentional,
willful, negligent or innocent, by any of the Lender Released Parties in
any way connected with, relating to or affecting, directly or indirectly,
the Loan, the Loan Documents or the relationship between Lender and
Borrower.

            B.    NON-RELIANCE.  Borrower hereby acknowledges that it has
not relied upon any representation of any kind made by Lender or any of the
Lender Released Parties in making the foregoing release.

            C.    CIVIL CODE.  Borrower is aware of the provisions of
Section 1542 of the California Civil Code, which Section reads as follows:

      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.

Borrower waives the provisions of said Section 1542 of the California Civil
Code and the provisions of any other applicable laws restricting the
release of claims which the releasing parties do not know or suspect to
exist at the time of release, which, if known, would have materially
affected the decision of Borrower to agree to this Agreement.

            D.    NO ADMISSION OF LIABILITY.  It is hereby further
understood and agreed that the acceptance of delivery of this Agreement by
the parties released hereby shall not be deemed or construed as an

and purpose of this Agreement.

account conflicts of law).

      9.    AMENDMENTS.  This Agreement may be amended by written agreement
of amendment executed by all parties, but not otherwise.
