      	1.    	
              Borrower
                promises to and shall pay Lender the principal of Two Hundred and
                Twenty
                Five Thousand Dollars ($225,000.00), plus interest in the amount
                of Twenty
                Two Thousand and Five Hundred Dollars ($22,500.00), on or before
                the 24th
                day of October 2005 (“Maturity”
                or
                “Maturity
                Date”).
                The entire unpaid balance of the principal and interest, if not sooner
                paid, shall be and become due and payable at
                Maturity.

            

      

      	2.    	
              Additional
                interest. In addition to the interest due and payable hereunder at
                the
                Contract Rate, Borrower shall pay to Lender as additional
                interest:

            

      

      	(a)  	
              The
                Late Charge as provided in paragraph 6 hereafter, when
                applicable;

            

      	 	 

      	(b)  	
              The
                Default Fee as provided in paragraph 7 hereafter
                and,

            

      	 	 

      	(c)  	
              The
                Additional Sums as set forth in paragraph 14 hereafter, when
                applicable.

            

      

      	3.    	
              Place
                of payment. Borrower shall make all payments to Lender at 14170 Victor
                Place, Saratoga, California 95070, or at such other place or places
                as
                Lender may designate in writing from time to
                time.

            

      

      	4.    	
              Lawful
                money. All payments shall be in lawful money of the United States
                of
                America or in such other form which is acceptable to Lender.
                Lender’s
                acceptance of payment in any form other than lawful money of the
                United
                States of America for any partial payment required or permitted under
                the
                provisions of this Note shall not be a waiver of the requirement
                that any
                future payments be made in lawful money of the United States of
                America.

            

      

      	5.    	
              No
                Prepayment penalties. Borrower shall have the right and option to
                prepay
                this Note at any time prior to maturity without penalty or
                premium.

            

      

      	6.    	
              Late
                charge. Should the payment of principal and interest not be paid
                in full
                at Maturity, it is recognized by Borrower that Lender will incur
                extra
                expenses for handling of delinquent payments, the exact amount of
                such
                extra expense being the sum of Eleven thousand, Two Hundred and Fifty
                Dollars ($11,250.00). Therefore, in such event, the principal amount
                of
                Two Hundred and Twenty Five Thousand Dollars ($225,000.00), plus
                interest
                in the amount of Twenty Two Thousand and Five Hundred Dollars
                ($22,500.00), and late charge of Eleven Thousand, Two Hundred and
                Fifty
                Dollars ($11,250.00) shall be due and payable on or before the
                23rd
                day of November, 2005, or Borrower is to be declared in default
                hereunder.

      	7.    	
              Default:
                This instrument is to be secured against loss as indicated in paragraph
                12.

            

      

      	8.    	
              Remedies
                cumulative. The rights or remedies of Lender as provided in any of
                the
                Purchase Documents shall be cumulative and concurrent, and may be
                pursued
                singularly, successively, or together against Borrower, any Guarantor
                hereof, and any other funds, property or security held by Lender
                for the
                payment hereof or otherwise at the sole, absolute and uncontrolled
                discretion of Lender. The failure to exercise any such right or remedy
                shall in no event be construed as a waiver or release of said rights
                or
                remedies or of the rights to exercise them at any later
                time.
