ULTRASTRIP SYSTEMS, INC., a Florida corporation ("Maker") (Maker and each
endorser, surety or guarantor, are collectively herein called "Obligor"),
promises to pay to the order of VINCENT ZANFINI, ("Lender"; Lenders and each and
all subsequent holders of this note are included in the terms "Holder"), at 4701
Bimini Circle North, Palm City FL. 34990 (or at such other place as the Holder
hereof may designate), the sum of ONE HUNDRED THOUSAND AND 00/00 DOLLARS
($100,000.00) with interest at the Applicable Interest Rate, as defined below.
Interest on principal will accrue at the Applicable Interest Rate from May 28,
2004 at the rate of 1/360th of annual interest for each day that principal is
outstanding; provided, however, in no event shall interest be due at a rate in
excess of the maximum permissible legal rate.

Principal and interest shall be payable as follows:

         a.       The entire outstanding principal balance of the note and
                  interest shall be due and payable in full on or before August
                  28, 2004 (the "Maturity Date").

         b.       The "Applicable Interest Rate" shall be eighteen percent (18%)
                  per annum.

         c.       This note may be prepaid at any time in whole or in part,
                  without premium or penalty.

         d.       Lender and Holder may agree to extend Promissory Note an
                  additional three (3)months.

As used in this instrument, the term "Obligations" shall refer to the
indebtedness represented by this note and all modifications, renewals and
substitutions hereof.

The happening of any of the following events shall constitute a default
hereunder: (1) failure of Obligor to pay in full when due any indebtedness,
obligation, or liability to the Holder whatsoever, or any installment thereof or
interest thereon; (2) failure of Obligor to perform any agreement hereunder; (3)
the Holder learns that any warranty, representation, certificate or statement of
Obligor (whether contained in this note or not) pertaining to or in connection
with this note or the loan or credit evidenced by this note, is not true; (4)
Obligor becomes insolvent or any insolvency proceedings (as said terms
"insolvent" and "insolvency proceedings" are defined in the Uniform Commercial
Code of Florida) are instituted or made by or against Obligor, or application is
made for the appointment of a receiver for Obligor or for any of the assets of
Obligor; (5) the entry of a judgment against Obligor; (6) the issuing of any
levy, attachment or garnishment, or the filing of any lien against any property
of Obligor; or (7) the dissolution, merger, consolidation, or reorganization of
Obligor.

Upon the happening of any default as defined herein the entire amount of this
note remaining unpaid, shall, at the option of the Holder and without notice or
demand, become due and payable forthwith or thereafter. In the event of any
default hereunder, after deducting any paid and unaccrued or paid and unearned
interest from the principal balance then due, the then unpaid principal balance
hereof and any accrued and unpaid interest shall bear interest from the time of
such default at the maximum legal rate permissible (the "Default Rate"), and,
regardless of the payment terms of the note, and all unpaid interest from the

<PAGE>

time of such default may be compounded on a monthly basis, the first such
compounding to be made 30 days after the default and, thereafter, on the same
date of each subsequent month until all Obligations have been paid in full. In
no event and under no circumstances shall there be due hereunder, nor shall the
Holder be entitled hereunder to receive at any time, any charges not allowed or
permitted by law or any interest or interest rate in excess of the maximum
allowed by law. In the event that the amount of any charge or payment due
hereunder shall create or shall be deemed to create an interest charge in excess
of the maximum permissible legal rate, then the charge of any such excess amount
shall be deemed unenforceable and void and its collection shall be waived,
without affecting the remainder of the Obligations evidenced hereby, and any
such excess amount which may have been paid to the Holder shall be refunded.

In the event the Holder shall be required at any time to pay documentary stamp
tax, intangible tax, or other taxation with respect to all or part of the Loan
or any other transaction contemplated or evidenced by this note, the Obligor
shall reimburse the Holder immediately for all such costs, including any
interest and penalties with respect thereto.

With respect to any and all Obligations, the Obligor waives the following: (1)
demand, presentment, protest, notice of dishonor, suit against any party and all
other requirements necessary to charge or hold Obligor liable on any Obligation;
(2) any further receipt for or acknowledgment of the Collateral now or hereafter
deposited or statement of indebtedness; (3) the right to interpose any set-off
or counterclaim of any nature or description in any litigation in which the
Holder and Obligor shall be adverse parties. The Obligor agrees that any
Obligations of Obligor may, from time to time, in whole or in part, be renewed,
extended, modified, accelerated, compromised, discharged or released by the
Holder, all without notice to or further reservations of rights against Obligor
and all without in any way affecting or releasing the liability of Obligor. The
Obligor agrees to pay all taxes and assessments levied on or with respect to the
Obligations, this note, including but not limited to intangible and documentary
stamp taxes, and all filing fees and taxes and all costs of collecting or
securing or attempting to collect or secure any Obligations, including
attorneys' fees, whether or not involving litigation and/or appellate
proceedings.

The Holder shall not by any act, delay, omission or otherwise be deemed to have
waived any of its rights or remedies, and no waiver of any kind shall be valid,
unless in writing and signed by the Holder. All rights and remedies of the
Holder under the terms of this note and under any statutes or rules of law shall
be cumulative and may be exercised successively or concurrently. The Obligor
agrees that the Holder shall be entitled to all the rights of a holder in due
course of a negotiable instrument. This note shall be governed by and construed
in accordance with the laws of the State of Florida. Any provision of this note,
which may be unenforceable or invalid under any law, shall be ineffective to the
extent of such unenforceability or invalidity without affecting the
enforceability or validity of any other provision hereof. Any notice required to
be given to any person shall be deemed sufficient if mailed, postage prepaid, to
such person's address as it appears on this note, or, if none appears, to any
address in the Holder's files. The Holder shall have the right unilaterally to
correct patent errors in this note and to fill in any blank spaces herein so as
to conform to the terms upon which the loan evidenced hereby is made.

The Obligor shall be liable for all indebtedness represented by this note and
have subscribed their names hereto without condition that anyone else should
sign or become bound hereon and without any other condition whatever being made.
The provisions of this note are binding on the heirs, executors, administrators,
assigns and successors of Obligor and shall inure to the benefit of the Holder,
its successors and assigns. This note is executed under the seal of the Obligor.

This promissory note constitutes and evidences the complete understanding
between the Holder and the Obligor. All prior and contemporaneous discussions
between the Holder and the Obligor, including all representations and promises
by the Holder, whether oral or written, concerning the Obligations, are included

writing and signed by the Holder and the Obligor shall be void, except that the
Holder may in its sole discretion extend the maturity of the loan evidenced by
this note for a term specified in a written notification mailed to the Obligor
at its address shown on the Holder's records. The Holder may rely on the
information, instructions, or other communications (including requests for and
directions concerning loan advances) given to the Holder by the Obligor.

Notwithstanding anything herein to the contrary, Holder agrees, by acceptance of
this note, to forbear acceleration of the unpaid principal balance hereof (a)
for a period of 10days for the failure of the Obligor to make a payment when due
hereunder. Such forbearance shall not deny or in any way mitigate the occurrence
of a default, unless the Obligor, within the applicable forbearance period,
cures such default to Holder's satisfaction, in which event the Loan shall
thereupon be reinstated and restored to good standing in all respects, including
the interest rate hereon, effective as of the date of the default.

No invalid provision of this note shall affect or impair any other provision.
Maker and Obligor acknowledge receipt of a completed copy of this Note.

ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS PROMISSORY NOTE, OR WITH
RESPECT TO DEALINGS BETWEEN THE HOLDER AND THE OBLIGOR CONCERNING ANY COURSE OF
CONDUCT, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF EITHER PARTY. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR THE HOLDER TO PROVIDE CREDIT TO THE
OBLIGOR.

1.01 Representations and Warranties. The Purchaser represents and warrants as
follows:

         (a) The Purchaser has relied solely on the information contained in
that certain Private Placement Memorandum dated June 6, 2003 and the Company's
10-KSB filing with the U.S. Securities and Exchange Commission for the year
ended December 31, 2002, which the Purchaser has carefully reviewed. No oral
representations have been made or oral information furnished to the Purchaser in
connection with the Memorandum. The Purchaser and its advisors have had a
reasonable opportunity to ask questions of and receive answers from the
Corporation concerning the Warrants and/or Shares.

         (b) The Purchaser has been supplied with or has sufficient access to
all information, including financial statements and other financial information
of the Corporation, and has been afforded an opportunity to ask questions of and
receive answers from officers of the Corporation concerning information to which
a reasonable investor would attach significance in making investment decisions.

         (c) The Purchaser is not subscribing for the Warrants and/or Shares as
a result of or subsequent to any advertisement, articles, notice or other
communication published in any newspaper, television or radio broadcast, or
presented at any seminar or meeting, or any solicitation of a subscription by a
person not previously known to the Purchaser in connection with investments in
securities generally.

         (d) The Purchaser has adequate means of providing for his current
financial needs and contingencies, is able to bear the substantial economic
risks of an investment in the Warrants and/or Shares for an indefinite period of
time, has no need for liquidity in such investment, and has made commitments to
investments that are not readily marketable which are reasonable in relation to
the Purchaser's net worth and can afford a complete loss of such investment.

         (e) The Purchaser has such knowledge and experience in financial, tax
and business matters so as to enable him to utilize the information made
available to him in connection with the offering of the Warrants and/or Shares
to evaluate the merits and risks of an investment in the Warrants and/or Shares
and to make an informed investment decision with respect thereto.

         (f) The Purchaser is not relying on the Corporation with respect to the
tax and other economic consideration of an investment in the Warrants and/or
Shares, and the Purchaser has relied on the advice of, or has consulted with,
only the Purchaser's own advisors.

Agreement and make an investment in the Corporation and, if the Purchaser is an
entity, is authorized and otherwise duly qualified to purchase and hold the
Warrants and/or Shares and to enter into this Agreement.

have not been registered under the Securities Act of 1933, as amended (the
"Securities Act"), or under the securities laws of certain states and,
therefore, cannot be re-sold, pledged, assigned or otherwise disposed of unless

<PAGE>

the securities are subsequently registered under the Securities Act and under
the applicable securities laws of such states or unless an exemption from such
registration is available in the opinion of counsel reasonably satisfactory to
counsel for the Corporation. The Purchaser is purchasing the Warrants and/or
Shares for the Purchaser's own account, for investment and not with a view to
resale or distribution except in compliance with the Securities Act and
applicable state securities laws. The Purchaser further acknowledges that there
is presently no market for the purchase and sale of the Warrants and/or Shares
and that no such market may ever exist.

         (i) The Purchaser agrees to the placement of a legend on any
certificate or other document evidencing the Warrants and/or Shares, stating
that they have not been registered under the Securities Act.

         (j) The Purchaser maintains his domicile, and is not merely a transient
or temporary resident, at the residence address shown on the signature page
hereto.

         (k) The representations, warranties and agreements contained herein and
in the related Investor Qualification and Questionnaire are true and correct as
of the date hereof and may be relied upon by the Corporation and, the Purchaser
will notify the Corporation immediately of any adverse change in any such
representations and warranties which may occur prior to the acceptance of this
Agreement by the Corporation and will promptly send the Corporation written
confirmation thereof. The representations, warranties and agreements of the
Purchaser contained herein shall survive the execution and delivery of this
Agreement and the purchase of the warrants and/or shares.

below by the Purchaser's initials (initial one or more of the following four
statements):

         (i) I certify that I am an accredited investor because I have had

$200,000 in 2002 and 2003 and I reasonably expect to have an individual income
in excess of $200,000 in 2004.

         (ii) I certify that I am an accredited investor because I have had
joint income with my spouse in excess of $300,000 in 2002 and 2003 and I
reasonably expect to have joint income with my spouse in excess of $300,000 in
2004.

         (iii) I certify that I am an accredited investor because I have an
individual net worth, or my spouse and I have a joint net worth, in excess of
$1,000,000

2.01 Warrants to be Sold . Upon the terms and subject to the conditions
contained herein, upon execution hereof the Purchaser shall purchase and accept
from the Corporation the Warrants, and the Corporation shall sell and cause the
transfer to Purchaser of the Warrants.

           SUBSCRIPTION AGREEMENT PAGE 3 OF 6 ULTRASTRIP SYSTEMS, INC.

<PAGE>

2.02 Consideration . Upon execution hereof, Purchaser shall deliver to the
Corporation a fully executed Extension of Maturity of Note Agreement, as
referenced above, for the Warrants. The delivery of the Warrants is further
conditioned upon Purchaser providing to Corporation the loan proceeds as
described in a certain promissory note extension dated February 12, 2004 between
the Parties.

2.03 Stock Split/Dividend. During the period Purchaser owns the subject
Warrants, in the event the shares of the Corporation complete a stock split or
if the corporation declares and issues a stock dividend, Purchaser shall be
entitled to a multiple of the Warrants held by Purchaser equal to the stock
split or stock dividend multiple of the Corporation. By way of example, if the
Corporation's publicly traded stock splits in which each shareholder receives
two shares of stock for each single share held, Purchaser shall be entitled to
two Warrants for each single Warrant held by Purchaser under the same terms and
conditions for exercises except that the strike price will be adjusted in
proportion to the stock split or the stock dividend.

                                   ARTICLE III
                                 INDEMNIFICATION

3.01 Indemnification. The Purchaser agrees to indemnify and hold the Corporation
and its agents, representatives and employees harmless from and against all
liability, damage, loss, cost and expense (including reasonable attorneys' fees)
which they may incur by reason of the failure of the Purchaser to fulfill any of
the terms or conditions of this Agreement, or by reason of any inaccuracy or
omission in the information furnished by the Purchaser herein or any breach of
the representations and warranties made by the Purchaser herein or in any
document provided by the Purchaser to the Corporation.

                                   ARTICLE IV

4.01 Miscellaneous.

         (a) This Agreement has been duly and validly authorized, executed and
delivered by the Purchaser and constitutes the valid, binding and enforceable
agreement of the Purchaser. If this Agreement is being completed on behalf of an
entity it has been completed and executed by an authorized party.

         (b) The Memorandum, this Agreement and any documents referred to herein
constitute the entire agreement between the parties hereto with respect to the
subject matter hereof and together supersede all prior discussions or agreements
in respect hereof.

         (c) Within five (5) days after receipt of a written request from the
Corporation, the Purchaser agrees to provide such information, to execute and
deliver such documents and to take, or forbear from taking, such actions or
provide such further assurances as reasonably may be necessary to correct any
errors in documentation or to comply with any and all laws to which the
Corporation is subject or to effect the terms of the Memorandum.

         (d) The Corporation shall be notified immediately of any change in any
