4.     Prepayment. The principal amount of this Convertible Promissory Note and
any accrued and unpaid interest thereon may be prepaid, in whole or in part, by
Maker without penalty or premium. Partial prepayments shall be applied first to
accrued and unpaid interest and then to principal. Such prepayment may be made
at any time without notice, provided, however, that in the event that Payee
shall have the right to convert any portion of the principal amount of this
Convertible Promissory Note as provided in Section 9, Maker shall give the Payee
ten (10) days’ notice of any such prepayment and, during such 10-day period,
Payee ’s rights in respect of conversion shall be unaffected by the giving of
such notice.

5.     Covenants.

a.      Restriction on Major Transactions. The Surviving Corporation (as that
term is defined in the Merger Agreement)) or any other person or entity in which
it directly or indirectly controls (each such person or entity being a
“Subsidiary”) without the prior written consent of Payee, to agree to or

of shares, recapitalization, reorganization, redemption or other similar event
or to transfer any of its property or assets outside the ordinary course of
business.

mortgage, pledge or otherwise dispose of any shares or interests in any
Subsidiary, nor will it permit any Subsidiary to transfer, mortgage, pledge or
otherwise dispose of any shares or interests in a Subsidiary held by it. Maker
represents and warrants that it does not own any interest in a person or entity
that is not a Subsidiary.

c.      Amendment of Target’s Articles of Incorporation. Maker will not permit
Target to amend its articles of incorporation.

d.      Filing of Reports under the Exchange Act; No Termination of Exchange Act

Stock under Section 12(b) or (g) of said Act. After any conversion under Section
9 of this Convertible Promissory Note and for as long as the Payee holds any of
the shares of Common Stock issued upon such conversion, Maker shall give
immediate notice only by personal delivery or e-mail to the Payee upon becoming
aware of Maker’s failure to comply with the covenant set forth in this
subsection (d).

e.      No Registration Statement. Maker shall not file any registration
statement under the Securities Act of 1933 until one year after the date on
which the Payee shall first have converted any portion of this Promissory into
shares of Common Stock pursuant to Section 9, provided that Maker may comply
with its obligations under any agreement under which it is obligated to register
shares of its Common Stock issued in the Private Placement, as that term is
defined in the Merger Agreement.

--------------------------------------------------------------------------------

6.     Waiver of Demand, Etc. Payee waives demand, presentment, protest and
notice of any kind and consents to the extension of time for payments or other

7.     Remedies. If an Event of Default occurs and is continuing, Payee may, by
written notice given to Maker, declare the principal of and accrued interest on
this Convertible Promissory Note to be due and payable immediately; provided,
however, that upon the occurrence of any Event of Default described in Section
8(c), the principal of and accrued interest on this Convertible Promissory Note
shall automatically become due and payable immediately without the requirement
notice or any other action on the part of Payee. In the event that any action is
commenced by Payee to enforce his rights under this Convertible Promissory Note
and Payee prevails in such action, Maker shall reimburse Payee for Payee’s costs
and expenses, including, without limitation, reasonable legal fees, incurred in
connection therewith. Maker acknowledges that in the event that if it were to

(b) Maker shall fail to comply with any of its other obligations under this
Convertible Promissory Note, other than its obligations under Section 5, and
such default shall continue unremedied for a period of fifteen (15) days after
written notice from Payee, provided, however, that in the event that such
default cannot with diligence be cured within said period, Payee shall have such
period as is reasonable to cure such default;

(c) Maker or any Subsidiary: (i) shall commence a voluntary case under any
Bankruptcy Law (as hereinafter defined); (ii) shall become subject to an

9.     Conversion.

3

--------------------------------------------------------------------------------

(a)     Conversion. In the event of the default set forth in Section 8(a), the
Payee shall have the right, at his option, to convert, subject to the terms and
provisions of this Section 9, all or any portion of the unpaid principal amount
of this Convertible Promissory Note and the interest accrued thereon (the sum of
such unpaid principal amount and such accrued interest as it shall exist from
time to time being the “Convertible Amount”) into the number of fully paid and
nonassessable shares of the common stock, par value $0.001 per share (“Common
Stock”) as shall be equal to the portion of the Convertible Amount that the
Payee desires to convert divided by the Conversion Price (as that term is
hereinafter defined) then in effect, by delivery of this Convertible Promissory
Note to the Maker at its address for notice; provided, however, that Payee shall
make no conversion for less than the portion of the Convertible Amount equal to
the amount of accrued interest then owing; and provided, further, that Maker
shall not issue any fractional shares in connection with any conversion pursuant
to this Section 9, but shall round up any fractional share to the next highest
share. In the event that the Payee shall exercise his option to convert this
Convertible Promissory Note with respect to less than the entire Convertible
Amount then existing, Maker shall issue to the Payee a new convertible
promissory note (the “Reissued Note”), duly executed by Maker, identical with
this Convertible Promissory Note, except that (i) the principal amount of the
Reissued Note shall be equal to the portion of the Convertible Amount Note that
has not been so converted, (ii) the Reissued Note shall be dated as of the
Conversion Date (as that term is hereinafter defined). The Conversion Price (as
that term is hereinafter defined) for the Reissued Note shall be the same as
that for this Convertible Promissory Note, except that any change in the
Conversion Price that would be applicable to this Convertible Promissory Note if
it had not been so replaced shall be given effect in determining the Conversion
Price for the Reissued Note. The shares deliverable upon any such conversion are
referred to as “Shares”.

(b)     Delivery of Stock Certificates; Time Conversion Effective; No Adjustment
for Interest or Dividends. As promptly as practicable after the surrender (as
herein provided) of this Convertible Promissory Note for conversion, Maker shall
deliver or cause to be delivered to or upon the written order of the Payee,
certificates representing the number of fully paid and nonassessable Shares into
which all or a portion of the Convertible Amount shall have been converted.
Subject to the following provisions of this Subsection (b), such conversion
shall be deemed to have been made at the close of business on the date on which
this Convertible Promissory Note shall have been surrendered for conversion as
provided in Subsection (a) of this Section 9 (the “Conversion Date”), so that
the rights of the Payee under this Convertible Promissory Note as such (only to
the extent that the Convertible Amount is converted) shall cease at such time
and the person or persons entitled to receive the Shares upon such conversion
shall be treated for all purposes as having become the record holder or holders
of such Shares at such time; provided, however, that no such surrender on any
date when the stock transfer books of Maker shall be closed shall be effective
to constitute the person or persons entitled to receive Shares upon such
conversion as the record holder or holders of such Shares on such date, but such
surrender shall be effective to constitute the person or persons entitled to
receive such Shares as the record holder or holders thereof for all purposes at
the close of business on the next succeeding day on which such stock transfer
books are open or Maker is required to effect such conversion.

If the day for the exercise of the conversion right shall not be a business day
at the palace where notice of conversion is to be given, then such conversion
right will be deemed to be exercised on the next succeeding day which is a
Business Day.

4

--------------------------------------------------------------------------------

No adjustments in respect of interest or cash dividends shall be made upon
conversion of this Convertible Promissory Note.

(c)     Conversion Price. The conversion price for this Convertible Promissory
Note (the “Conversion Price”) shall be fifty percent (50%) of the Current Market
Price. As used in the previous sentence, the term “Current Market Price” shall
mean the average of the daily closing price for a share of Common Stock for the
three (3) consecutive trading days ending on the trading day immediately prior
to the day on which this Convertible Promissory Note is delivered for conversion
pursuant to Subsection (a) of this Section 9. A trading day shall be any day on
which the Common Stock is able to be traded on an organized securities market or
trading system in the United States of America, whether or not the Common Stock
actually is traded on such day. The closing price for each day shall be the last
reported sales price, or, in case no reported sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case, as
quoted on the principal United States market for the Common Stock, as determined
by the Board of Directors of the Corporation or if, in the judgment of the Board
of Directors of the Corporation, there exists no principal United States market
for the Common Stock, then as determined by the Board of Directors of the
Corporation.

(d)     Consolidation or Merger. If Maker shall at any time consolidate or merge
with or into another corporation, (i) Maker shall give at least five (5) days’
prior written notice to the Payee of such consolidation or merger and the terms
thereof and (ii) the Payee shall thereafter be entitled to receive, upon the
conversion thereof, the securities or property to which a holder of the number
of Shares then deliverable upon the conversion thereof would have been entitled
upon such consolidation or merger. Maker shall take such steps in connection
with such consolidation or merger as may be necessary to assure such holder that
the provisions of this Agreement shall thereafter be applicable, as nearly as
reasonably may be in relation to any securities or property thereafter
deliverable upon the conversion of this Convertible Promissory Note including,
but not limited to, obtaining a written acknowledgement from the continuing
corporation or other appropriate corporation of its obligation to supply such
securities or property upon such conversion. The sale of all or substantially
all of the assets of Maker shall be deemed a consolidation or merger for the
foregoing purposes.

(e)     Taxes on Conversion. The issuance of certificates for Shares upon the
conversion of this Convertible Promissory Note shall be made without charge to
the Payee for any issue or stamp tax in respect of the issuance of such
certificates, and such certificates shall be issued in the respective names of,
or in such names as may be directed by, the holder of this Convertible
Promissory Note; provided, however, that Maker shall not be required to pay any
tax which may be payable in respect of any transfer involved in the issuance and
delivery of any such certificate in a name other than that of the Payee and
Maker shall not be required to issue or deliver such certificates unless or
until the person or persons requesting the issuance thereof shall have paid to
Maker the amount of such tax or shall have established to the satisfaction of
Maker that such tax has been paid.

10.     Usury. In no event whatsoever shall the amount of interest paid or
agreed to be paid to Payee exceed the maximum amount permissible under
applicable law. If Payee shall receive as interest, an amount which would exceed
the highest lawful rate, the amount which would be excessive interest shall be
applied to the reduction of the principal amount outstanding under this
Convertible Promissory Note (without prepayment premium or penalty).

--------------------------------------------------------------------------------

11.     Assignment, Amendment, Etc. This Convertible Promissory Note may be
assigned, transferred, sold or pledged by Payee without the prior written
consent of Maker. This Convertible Promissory Note shall be binding upon Maker
and its successors and assigns and shall inure to the benefit of Payee and
Payee’s heirs, executors, administrators and permitted assigns. If any term of
this Convertible Promissory Note shall be held invalid, illegal or
unenforceable, the validity of all other terms and provisions hereof shall in no
way be affected thereby. This Convertible Promissory Note may not be changed,
modified or terminated orally, but only by an agreement in writing, signed by
the party to be charged therewith. No delay, failure or omission by Payee or any
subsequent holder in respect of the exercise of any right or remedy granted
hereunder or allowed by law to Payee or other holder shall constitute a waiver
of the right to exercise the same at any future time or in the same or other
circumstances.

12.     Governing Law; Submission to Jurisdiction; Waiver of Jury Trial. This
Convertible Promissory Note shall be governed by and construed in accordance
with the laws of the State of Florida without giving effect to the principles of

b.     WAIVES TO THE FULL EXTENT PERMITTED BY APPLICABLE LAW ANY RIGHT IT MAY
