remedies available at law, in equity or by constitution, statute, rule,

the entire principal balance and accrued but unpaid interest due from the Maker
to be immediately due and payable in full. The Maker shall be liable for
Additional Amounts, as defined in Section 1.b. of this Note.

      In no event shall a waiver of rights or remedies arise solely from the
oral representations of the Holder or from any delay by it in exercising, or any
past failures to exercise, rights or remedies. A waiver of rights and remedies
by the Holder shall not be effective or binding unless, and then only to the
extent that, such waiver appears in this Note, or the Holder signs an express
written waiver of rights or remedies and causes such written waiver to be
delivered to the Maker.

      The Maker, to the maximum extent permitted by law, hereby waives each of
the following: (a) the benefit of, and the right to assert, any statute of
limitations defenses affecting the Maker's rights, duties or obligations under
this Note; (b) presentation, demand, protest, notices of dishonor and protest
and the benefits of homestead exemptions; and (c) all defenses and pleas with
respect to any extensions of the time for payment under this Note, except as may
be granted expressly by the Holder, in its sole discretion, in a written
instrument signed by the Holder and delivered to the Maker.

      6. Governing Law. The Holder shall be entitled to have all of its claims,
causes of action, suits, demands, counterclaims and defenses under this Note
interpreted and enforced in accordance with the laws of the State of California,
without regard to any conflicts of law provisions or principles thereof to the

or its respective successors and assigns.

      8. Assignment. The Maker shall not assign or delegate, whether in whole or
in part, any of its rights, duties or obligations under this Note, and any
attempted assignment or delegation in violation of this Note shall be void.

each valid and enforceable provision shall remain in full force and effect,
regardless of any determination that is binding upon the parties hereto and that
renders other provisions of this Note invalid or unenforceable To the extent, if
any, that a court of competent jurisdiction determines that certain provisions
of this Note are invalid or unenforceable, the Maker and the Holder hereby
authorize such court to modify such provisions, in a manner consistent with the
intent of the Maker and the Holder, as such court deems reasonably necessary to
make such provisions valid and enforceable.
