                                                               Boulder, Colorado

$5,000.00                                                      November 14, 1999

     THIS PROMISSORY NOTE (hereinafter referred to as the "Note") amends and
replaces that certain Promissory Note dated July 13, 1999 (hereinafter referred
to as the "July 13, 1999, Promissory Note") payable by Hercules Development
Group, Inc., as the maker thereof, to Bradley A. Scott, as the holder thereof,
in the principal amount of $5,000, bearing interest at the rate of eight per
cent (8%) per annum, which matured on November 13, 1999. The July 13, 1999,
Promissory Note shall be null and void for all purposes.

     For value received, the undersigned, Hercules Development Group, Inc.
(hereinafter referred to as the "Maker"), agrees and promises to pay to the
order of Bradley A. Scott (hereinafter referred to as the "Holder"), at 1442
Marigold Drive, Lafayette, Colorado 80301, or such other place as the Holder may
designate in writing, in coin or currency of the United States of America, which
at the time of payment is legal tender for the payment of public and private
debts, the principal sum of five thousand dollars ($5,000.00), together with
interest thereon at the rate of eight per cent (8%) per annum, from the date
hereof until maturity, as hereinafter provided.

     This Note is due and payable as follows: on November 13, 2000, the sum of
$5,000.00, plus interest at the rate of 8% per annum ($133.33), for a total sum
of $5,133.00.

     Any installment or other payment made by the Maker shall be applied first
to the payment of accrued interest due on the unpaid principal balance and the
remainder of any installment or other payment made by the Maker shall be applied
to the reduction of unpaid principal. This Note may be prepaid in whole or in
part at any time without penalty.

     If default is made in the payment of this Note, as and when the same is or
becomes due, the owner and holder of this Note may, after notice and failure to
cure as hereinafter provided, without additional notice or demand, declare the
entire unpaid principal balance hereof and accrued interest 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, bringing of suit and
diligence in taking any action to collect amounts called for 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 any payment hereunder is not made when due or in the event of default in
any other covenant, condition or promise under this Note, the principal shall,
at the option of the Holder and without further notice, immediately become due
and payable in full. From and after the date of such default, the principal sum
and all interest, then accrued shall bear interest at the rate of eighteen
percent (18%) per annum until paid.

     If the entire outstanding principal balance becomes due, the Maker agrees
to pay the Holder's reasonable costs (including reasonable attorney's fees and
court costs) in collecting on this Note, including the reasonable costs of
obtaining and enforcing a judgment for any balance due on this Note.
