as Exhibit A. The date of receipt (including receipt by telecopy) of such Notice of Conversion shall be the Conversion
Date.


 


4.
(a) The Holder of this Note is entitled, at its option, at any time after the 6 month anniversary of this Note, to convert
all or any amount of the principal face amount of this Note then outstanding into shares of the Company's common stock (the "Common
Stock") at a price ("Conversion Price") for each share of Common Stock equal to 65% of the lowest
VWAP of the Common Stock as reported on the National Quotations Bureau OTC Markets ex change which the
Company's shares are traded or any exchange upon which the Common Stock may be traded in the future ("Exchange"),
for the fourteen prior trading days including the day upon which a
Notice of Conversion is received by the Company or its transfer agent (provided such Notice of Conversion is delivered by fax
or other electronic method of communication to the Company or its transfer agent after 4 P.M. Eastern
Standard or Daylight Savings Time if the Holder wishes to include the same day closing price). If the shares have not been
delivered with in 3 business days, the Notice of Conversion may be rescinded. Such conversion shall be effectuated by the
Company delivering the shares of Common Stock to the Holder within 3 business days of receipt by the Company of the Notice of
Conversion. Accrued but unpaid interest shall be subject to conversion. No fractional shares or scrip representing fractions

all steps necessary to solicit the consent of the stockholders to reduce the par value to the lowest value possible under
law. The Company agrees to honor all conversions submitted pending this increase. In the event the Company experiences a
DTC "Chill" on its shares, the conversion price shall be decreased to 55% instead of 65% while that
"Chill" is in effect. In no event shall the Holder be allowed to effect a conversion if such conversion, along
with all other shares of Company Common Stock beneficially owned by the Holder and its affiliates would exceed 9.9% of
the outstanding shares of the Common Stock of the Company. The conversion discount and look back period will be adjusted on a
ratchet basis if the Company offers a more favorable conversion discount (whether through a straight discount or in
combination with an original issue discount) or look back period to another party while this note is in effect.

the applicable provision shall automatically be revised to equal the maximum rate of interest or other amount deemed interest
permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it will not seek to claim
or take advantage of any law that would prohibit or forgive the Company from paying all or a portion of the principal or interest
