All payments on this Note shall be applied first in payment of accrued interest
and any remainder in payment of principal.

If any installment is not paid when due, the remaining unpaid balance and
accrued interest shall become due immediately at the option of the Lender.

to the due date with no prepayment penalty.

promises to pay all costs of collection, including reasonable attorney fees,
whether or not a lawsuit is commenced as part of the collection process.

If any of the following events of default occur, this Note and any other
obligations of the Borrower to the Lender, shall become due immediately, without
demand or notice:

1)   the failure of the Borrower to pay the principal and any accrued interest
     in full on or before the Due Date;

2)   the death of the Borrower(s) or Lender(s);

3)   the filing of bankruptcy proceedings involving the Borrower as a Debtor;

5)   the making of a general assignment for the benefit of the Borrower's
     creditors;

6)   the insolvency of the Borrower;

     obtaining or extending credit.

In addition, the Borrower shall be in default if there is a sale, transfer,
assignment, or any other disposition of any assets pledged as security for the
payment of this Note, or if there is a default in any security agreement which
secures this Note.

If any one or more of the provisions of this Note are determined to be
unenforceable, in whole or in part, for any reason, the remaining provisions
shall remain fully operative.

All payments of principal and interest on this Note shall be paid in the legal
currency of the United States. Borrower waives presentment for payment, protest,
and notice of protest and nonpayment of this Note.

No renewal or extension of this Note, delay in enforcing any right of the Lender
under this Note, or assignment by Lender of this Note shall affect the liability
of the Borrower. All rights of the Lender under this Note are cumulative and may
be exercised concurrently or consecutively at the Lender's option.

This Note shall be construed in accordance with the laws of the State of New
Mexico.

Signed this 1st day  of  June, 2005
