     The Maker may prepay any part or all of this Note at any time without
penalty. Each payment or pre-payment made by the Maker hereunder shall be
applied first to the payment or rep- payment of accrued and unpaid interest, if
any, due on the unpaid principal balance of this Note and the remainder of each
payment or pre-payment made by the Maker shall be applied to the reduction of
the unpaid principal balance hereof.

     If default is made in the payment of this Note, as and when the same is or
becomes due the Holder may, after notice and failure to cure as hereinafter
provided, without additional notice or demand, declare the entire unpaid
principal balance hereof and accrued and unpaid interst, if any, at once due and
payable.

     Except as otherwise specifically set out herein, the Maker waives demand
and presentment for payment, notice of non-payment, protest, notice of protest,
notice of acceleration of the indebtedness due hereunder, and agrees that the
time of payments hereof may be extended without notice at any time and from
time-to-time, and for periods of time for a term or terms in excess of the
original term without notice or consideration to, or consent from the Maker
without same constituting a waiver of the Holder's rights under this Note.

     If payment is not received by the tenth day after it is due, then the
Holder agrees to give written notice of such to the Maker. If payment is not
received within five days of said notice then the Holder may at his election
accelerate this Note. The Holder may charge a late charge of two per cent (2%)

court costs) in collecting this Note, including the reasonable costs of
obtaining and enforcing a judgment for any balance due on this Note.

     This Note has been executed in the City identified in the heading and
delivered to the Holder at the address stated herein. It is to be performed, in
whole or in part, in the State of California, and the laws of such state shall
govern the validity, construction, enforcement and interpretation of this Note.
Jurisdiction and venue for any action hereunder shall be in the County of the
City identified in the heading.

     The Maker represents that it is duly authorized and empowered to enter
into, deliver, perform and be fully bound by all of the terms, provisions and
conditions of this Note. The Maker also represents that the making and delivery
of this Note, and the performance of any agreement or instrument made in
connection herewith, does not conflict with or violate any other agreement to
which the Maker is a party.

     No provision of this Note shall require the payment or permit the
collection of interest in excess of the maximum permitted by law, and in the
event of any such excess, neither the Maker nor its successors or assigns shall
be obligated to pay any such excess to the extent that it is more than the
amount permitted by law. If an excess amount is received, charged, collected or
applied as interest, it shall automatically be made so as to reduce the rate to
that permitted by law and any excess interest then received, charged or
collected shall be applied to reduce the amount of any collateral to which the
Holder is entitled.

     In the event that any word, phrase, clause, sentence or other provision
hereof shall violate any applicable statute, ordinance or rule of law in any
jurisdiction in which it is used, such provision shall be ineffective to the
extent of such violation without invalidating any other provision hereof.

     IN WITNESS HEREOF, this Note is executed on the date and year above
written.
