1.  A total of 160,000 shares were issued to Rick Langley from the
    Professional/Employee/Consultant Compensation Plan sponsored by
    the issuer, and filed with the SEC.  These shares were issued in lieu
    of cash monthly payments, a signing bonus for joining the company, and
    for expenses covered over the past 5 months.  This acquisition, therefore,
    is exempt from Section 16(b) of the Securities Exchange Act of 1934 under
    Rule 16b-3(a), and no Form 4 disclosure was required for that
    acquisition.  This form is being filed for Mr. Langley's impending change
    in beneficial ownership as a result of his selling these shares, from time
    to time, over the next 30-90 days, as such sales will reduce his beneficial
    holdings.  A Form 144 filing is also being filed to disclose the notice of
    sale.

2.  The price per share may vary.  This early filing is being made early on a
    voluntary basis.

3.  Rick Langley has an indirect interest in shares held in RHM Management,
    Inc., of which he is President and the majority shareholder.  RHM
    Management, Inc. holds 5,391,500 shares of Common Stock of the Issuer.
