If any installment of principal or interest is not paid within ten (10) business
days of the time and place specified herein, the entire amount unpaid shall be
due and payable forthwith at the election of the legal holder of this Note upon
notice to BSI2000. In the event of such acceleration of the Note by the legal
holder, interest shall thereupon commence to accrue at the lesser of 18% per
annum or the maximum rate permitted by law. The acceptance of any payment by the
legal holder hereof after the time when it becomes due as herein set forth shall
not be held to establish a custom or to waive any rights of the holder, whether
to enforce prompt payment of any future installment or otherwise. BSI2000 shall
have the right to prepay any and all amounts due hereunder without penalty or
prejudice.

The obligations of BSI2000 under this Note are secured by that certain Security
Agreement dated as of even date herewith between BSI2000 and The New Sytron,

the entire amount unpaid under this Note shall be due and payable forthwith at
the election of the legal holder of this Note upon notice to BSI2000. BSI2000
agrees to pay all reasonable costs of collection, including reasonable attorneys
fees if suit is brought on the Note. BSI2000 waives presentment, notice of
dishonor, and protest, and assents to any substitution or release of collateral.
No waiver of any payment or other rights under this Note shall operate as a
waiver of any other payment or rights. No delay or failure of the holder of this
Note in the exercise of any rights or remedy hereunder shall be deemed a waiver
of such rights by the holder and no exercise of any rights or remedies shall be
deemed a waiver of any other rights or remedy.

This Note shall be construed under and governed by the laws of the State of
Colorado, and all of the rights of the legal holder hereunder shall inure to the
benefit of its successors, assigns and personal representatives, and all
obligations of BSI2000 hereunder shall bind the successors and assigns of
BSI2000.
