____________________________ Dollars ($__________),on September ___, 2008 (the
"Maturity Date").

         This Note has been entered into pursuant to the terms of a subscription
agreement between the Borrower and the Holder, dated of even date herewith (the
"Subscription Agreement"), and shall be governed by the terms of such
Subscription Agreement. Unless otherwise separately defined herein, all
capitalized terms used in this Note shall have the same meaning as is set forth
in the Subscription Agreement. The following terms shall apply to this Note:

                                    ARTICLE I

                               GENERAL PROVISIONS

         1.1 PAYMENT GRACE PERIOD. The Borrower shall have a ten (10) day grace
period to pay any monetary amounts due under this Note, after which grace period
a default interest rate of ten percent (10%) per annum shall apply to the
amounts owed hereunder.

         1.2 CONVERSION PRIVILEGES. The Conversion Privileges set forth in
Article II shall remain in full force and effect immediately from the date
hereof and until the Note is paid in full regardless of the occurrence of an
Event of Default. The Note shall be payable in full on the Maturity Date, unless
previously converted into Common Stock in accordance with Article II hereof;
provided, that if an Event of Default has occurred (whether or not such Event of
Default is continuing), the Borrower may not pay this Note on or after the
Maturity Date, without the consent of the Holders holding 80% of the outstanding
principal amount of the Notes and aggregate Conversion Prices of Shares still
held by the Holders.

                                   ARTICLE II

                                CONVERSION RIGHTS

         The Holder shall have the right to convert the principal due under this
Note into Shares of the Borrower's Common Stock, $.001 par value per share
("Common Stock") as set forth below.

                                       1

<PAGE>

                  2.1. CONVERSION INTO THE BORROWER'S COMMON STOCK.

                  (a) The Holder shall have the right from and after the date of
the issuance of this Note and then at any time until this Note is fully paid, to
convert any outstanding and unpaid principal portion of this Note, and accrued
interest, at the election of the Holder (the date of giving of such notice of
conversion being a "Conversion Date") into fully paid and nonassessable shares
of Common Stock as such stock exists on the date of issuance of this Note, or
any shares of capital stock of Borrower into which such Common Stock shall
hereafter be changed or reclassified, at the conversion price as defined in
Section 2.1(b) hereof (the "Conversion Price"), determined as provided herein.
Upon delivery to the Borrower of a Notice of Conversion as described in Section
7 of the Subscription Agreement of the Holder's written request for conversion,
Borrower shall issue and deliver to the Holder within three (3) business days
from the Conversion Date ("Delivery Date") that number of shares of Common Stock
for the portion of the Note converted in accordance with the foregoing. At the
election of the Holder, the Borrower will deliver accrued but unpaid interest on
the Note in the manner provided in Section 1.3 through the Conversion Date
directly to the Holder on or before the Delivery Date (as defined in the
Subscription Agreement). The number of shares of Common Stock to be issued upon
each conversion of this Note shall be determined by dividing that portion of the
principal of the Note and interest to be converted, by the Conversion Price.

                  (b) Subject to adjustment as provided in Section 2.1(c)
hereof, the Conversion Price per share shall be the lower of (i) $.015 ("Maximum
Base Price"), or (ii) eighty (80%) of the average of the three lowest closing
bid prices for the Common Stock for the thirty (30) trading days prior to but
not including the Conversion Date for the Common Stock on the OTC Pink Sheets,
NASD OTC Bulletin Board, NASDAQ SmallCap Market, NASDAQ National Market System,
American Stock Exchange, or New York Stock Exchange, as applicable, or if not
then trading on any of the foregoing, such other principal market or exchange
where the Common Stock is listed or traded (whichever of the foregoing is at the
time the principal trading exchange or market for the Common Stock, the
"Principal Market"). Closing bid price shall mean the closing bid price as
reported by Bloomberg L.P., but in no event will the Conversion Price be greater
than $.015, subject to adjustment as described herein.

                  (c) The Maximum Base Price and number and kind of shares or
other securities to be issued upon conversion determined pursuant to Section
2.1(a), shall be subject to adjustment from time to time upon the happening of
certain events while this conversion right remains outstanding, as follows:

                           A. Merger, Sale of Assets, etc. If the Borrower at
any time shall consolidate with or merge into or sell or convey all or
substantially all its assets to any other corporation, this Note, as to the
unpaid principal portion thereof and accrued interest thereon, shall thereafter
be deemed to evidence the right to purchase such number and kind of shares or
other securities and property as would have been issuable or distributable on
account of such consolidation, merger, sale or conveyance, upon or with respect
to the securities subject to the conversion or purchase right immediately prior
to such consolidation, merger, sale or conveyance. The foregoing provision shall
similarly apply to successive transactions of a similar nature by any such
successor or purchaser. Without limiting the generality of the foregoing, the
anti-dilution provisions of this Section shall apply to such securities of such
successor or purchaser after any such consolidation, merger, sale or conveyance.

                           B. Reclassification, etc. If the Borrower at any time
shall, by reclassification or otherwise, change the Common Stock into the same
or a different number of securities of any class or classes that may be issued
or outstanding, this Note, as to the unpaid principal portion thereof and
accrued interest thereon, shall thereafter be deemed to evidence the right to

                                       2

<PAGE>

purchase an adjusted number of such securities and kind of securities as would
have been issuable as the result of such change with respect to the Common Stock
immediately prior to such reclassification or other change.

                           C. Stock Splits, Combinations and Dividends. If the
shares of Common Stock are subdivided or combined into a greater or smaller
number of shares of Common Stock, or if a dividend is paid on the Common Stock
in shares of Common Stock, the Conversion Price shall be proportionately reduced
in case of subdivision of shares or stock dividend or proportionately increased
in the case of combination of shares, in each such case by the ratio which the
total number of shares of Common Stock outstanding immediately after such event
bears to the total number of shares of Common Stock outstanding immediately
prior to such event..

                           D. Share Issuance. So long as this Note is
outstanding, if the Borrower shall issue any shares of Common Stock except for
the Excepted Issuances (as defined in the Subscription Agreement) for a
consideration less than the Conversion Price in effect at the time of such
issue, then, and thereafter successively upon each such issue, the Conversion
Price shall be reduced to such other lower issue price. For purposes of this
adjustment, the issuance of any security carrying the right to convert such
security into shares of Common Stock or of any warrant, right or option to
purchase Common Stock shall result in an adjustment to the Conversion Price upon
the issuance of security and again upon the issuance of shares of Common Stock
upon exercise of such conversion or purchase rights if such issuance is at a
price lower than the then applicable Conversion Price.

                  (d) Whenever the Conversion Price is adjusted pursuant to
Section 2.1(c) above, the Borrower shall promptly mail to the Holder a notice
setting forth the Conversion Price after such adjustment and setting forth a
brief statement of the facts requiring such adjustment.

                  (e) During the period the conversion right exists, Borrower
will reserve from its authorized and unissued Common Stock a sufficient number
of shares to provide for the issuance of Common Stock upon the full conversion
of this Note, but not less than the amount of shares of Common Stock required to
be reserved pursuant to the Subscription Agreement. Borrower represents that
upon issuance, such shares will be duly and validly issued, fully paid and
non-assessable. Borrower agrees that its issuance of this Note shall constitute
full authority to its officers, agents, and transfer agents who are charged with
the duty of executing and issuing stock certificates to execute and issue the
necessary certificates for shares of Common Stock upon the conversion of this
Note.

                  2.2 METHOD OF CONVERSION. This Note may be converted by the
Holder in whole or in part as described in Section 2.1(a) hereof and the
Subscription Agreement. Upon partial conversion of this Note, a new Note
containing the same date and provisions of this Note shall, at the request of
the Holder, be issued by the Borrower to the Holder for the principal balance of
this Note and interest which shall not have been converted or paid.

                  2.3. MANDATORY CONVERSION. Provided an Event of Default or an
event which with the passage of time or giving of notice could become an Event
of Default has not occurred, then, commencing after the Actual Effective Date,
the Borrower will have the option by written notice to the Holder ("Notice of
Mandatory Conversion") of compelling the Holder to convert all or a portion of
the outstanding and unpaid principal of the Note and accrued interest, thereon,
into Common Stock at the Conversion Price then in affect ("Mandatory
Conversion"). The Notice of Mandatory Conversion, which notice must be given on
the first day following twenty (20) consecutive trading days ("Lookback Period")

                                       3

<PAGE>

during which the closing price for the Common Stock as reported by Bloomberg, LP
for the Principal Market shall be greater than $0.05 and with a daily trading
volume amount of not less than 1,000,000 Shares on each such trading day. The
date the Notice of Mandatory Conversion is given is the "Mandatory Conversion
Date." The Notice of Mandatory Conversion shall specify the aggregate principal
amount of the Note which is subject to Mandatory Conversion. Mandatory
Conversion Notices must be given proportionately to all Holders of Notes and
Other Holders of Other Notes. The Borrower shall reduce the amount of Note
principal subject to a Notice of Mandatory Conversion by the amount of Note
Principal and interest for which the Holder had delivered a Notice of Conversion
to the Borrower during the twenty (20) trading days preceding the Mandatory
Conversion Date. Each Mandatory Conversion Date shall be a deemed Conversion
Date and the Borrower will be required to deliver the Common Stock issuable
pursuant to a Mandatory Conversion Notice in the same manner and time period as
described in Section 2.1 above and the Subscription Agreement. A Notice of
Mandatory Conversion may be given only in connection with an amount of Common
Stock which would not cause a Holder to exceed the 9.99% beneficial ownership
limitation set forth in Section 2.4 of this Note. A Notice of Mandatory
Conversion may be given only in connection with Common Stock that has been
included for resale in an effective Registration Statement during the entire
Lookback Period and through the Mandatory Conversion Date.

                  2.4 MAXIMUM CONVERSION. The Holder shall not be entitled to
convert on a Conversion Date that amount of the Note in connection with that
number of shares of Common Stock which would be in excess of the sum of (i) the
number of shares of Common Stock beneficially owned by the Holder and its
affiliates on a Conversion Date, (ii) any Common Stock issuable in connection
with the unconverted portion of the Note, and (iii) the number of shares of
Common Stock issuable upon the conversion of the Note with respect to which the
determination of this provision is being made on a Conversion Date, which would
result in beneficial ownership by the Holder and its affiliates of more than
9.99% of the outstanding shares of Common Stock of the Borrower on such
Conversion Date. For the purposes of the provision to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3
thereunder. Subject to the foregoing, the Holder shall not be limited to
aggregate conversions of only 9.99% and aggregate conversion by the Holder may
exceed 9.99%. The Holder shall have the authority and obligation to determine
whether the restriction contained in this Section 2.4 will limit any conversion
hereunder and to the extent that the Holder determines that the limitation
contained in this Section applies, the determination of which portion of the
Notes are convertible shall be the responsibility and obligation of the Holder.
The Holder may void the conversion limitation described in this Section 2.4 upon
and effective after 61 days prior written notice to the Borrower. The Holder may
allocate which of the equity of the Borrower deemed beneficially owned by the
Holder shall be included in the 9.99% amount described above and which shall be
allocated to the excess above 9.99%.

                                   ARTICLE III

                                EVENT OF DEFAULT

                  The occurrence of any of the following events of default
("Event of Default") shall, at the option of the Holder hereof, make all sums of
principal and interest then remaining unpaid hereon and all other amounts
payable hereunder immediately due and payable, upon demand, without presentment,
or grace period, all of which hereby are expressly waived, except as set forth
below:

                  3.1 FAILURE TO PAY PRINCIPAL OR INTEREST. The Borrower fails
