                                 PROMISSORY NOTE

$170,000.00                                                      October 3, 2002

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 DENNIS AND JACQUELINE MCGUIRE ("Lenders";
Lenders and each and all subsequent holders of this note are included in the
terms "Holder"), at 3515 SOUTHEAST LIONEL TERRACE, STUART, FLORIDA, 34997(or at
such other place as the Holder hereof may designate), the sum of ONE HUNDRED
SEVENTY THOUSAND AND 00/00DOLLARS ($170,000.00) with interest at the Applicable
Interest Rate, as defined below. Interest on principal will accrue at the
Applicable Interest Rate from October 3, 2002 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 note, together
                  with all accrued but unpaid interest thereon, shall be due and
                  payable upon demand by the Lenders (the "Maturity Date").

         b.       The "Applicable Interest Rate" shall mean the rate per annum
                  which is 2 % per annum in excess of the fluctuating prime rate
                  announced or established from time to time by Northern Trust
                  (the "Bank"), accruing on a 360-day basis on outstanding
                  principal. The prime rate is a reference rate only, and is not
                  necessarily the lowest or best rate offered by Bank for loans
                  to its borrowers. The Applicable Interest Rate shall
                  automatically adjust on each date that the Bank adjusts its
                  prime rate.

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

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) a failure of any Obligor to pay in full any installment payable
hereunder promptly when it becomes due; (2) failure of any Obligor to pay in
full when due any indebtedness, obligation, or liability to the Holder
whatsoever, or any installment thereof or interest thereon; (3) failure of any
Obligor to perform any agreement hereunder; (4) the Holder learns that any
warranty, representation, certificate or statement of any 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; (5) any 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 any Obligor, or application is made for the
appointment of a receiver for any Obligor or for any of the assets of any
Obligor; (6) the entry of a judgment against any Obligor; (7) the issuing of any
levy, attachment or garnishment, or the filing of any lien against any property
of any Obligor; or (8) the dissolution, merger, consolidation, or reorganization
of any Obligor.

<PAGE>

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
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 Obligors severally waive the
following: (1) demand, presentment, protest, notice of dishonor, suit against
any party and all other requirements necessary to charge or hold any 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 any Obligor shall be adverse parties. The
Obligors severally agree that any Obligations of any 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 any Obligor and all without in any way
affecting or releasing the liability of any Obligor. The Obligors jointly and
severally agree 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 Obligors
jointly and severally agree 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 Obligors shall be jointly and severally 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 each and every
Obligor and shall inure to the benefit of the Holder, its successors and
assigns. This note is executed under the seal of each of the Obligors.

This promissory note constitutes and evidences the complete understanding
between the Holder and the Obligors. 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
in and merged in this note. Any modification thereof hereafter which is not in
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 any one 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 each other Obligor acknowledge receipt of a completed copy of this
Note.

         RE:      Extension of Maturity of Note and Modification of Subscription
                  And Warrant Purchase Agreement

Dear Dr. Baratta:

         UltraStrip Systems, Inc., a Florida corporation ("UltraStrip"),
executed a Promissory Note in the principal amount of $862,069.00 as of October
19, 2001 (the "Note"), together with a Financing Agreement of even date
therewith (the "Financing Agreement") and a Subscription and Warrant Purchase
Agreement of even date therewith (the "Warrant Agreement"). On October 19, 2001,
the Creditor paid an additional $137,931 pursuant to the Warrant Agreement.

         The Initial Advances, together with all accrued but unpaid interest,
are due and payable, in full, on October 18, 2002. The Creditor has agreed to
extend the due date for the Initial Advances, together with all accrued but
unpaid interest thereon until January 17, 2003. In exchange for such agreement,
UltraStrip agrees to modify the Warrant Agreement by increasing the number of
Warrants from the existing number of 100,000 to a total of 162,500, an increase
of 62,500 Warrants. The additional 62,500 warrants will have a strike price of
$0.07 and will expire on October 18, 2022.

         UltraStrip hereby agrees, represents, warrants and covenants that (a)
there is no current or threatened breach and UltraStrip is in compliance with
all terms and conditions, under the Note, Financing Agreement and Warrant
Agreement other than the failure to pay the Initial Advances, together with
accrued but unpaid interest thereon, as of October 19, 2002, which date has been
extended as provided herein, (b) the Note, Financing Agreement and Warrant
Agreement remain in full force and effect except as otherwise amended as
provided herein, and (c) it has no claims, actions or causes of actions against
the Creditor as of the date hereof.

         Any ambiguities between the terms of this letter and the Note,
Financing Agreement, and the Warrant Agreement shall be resolved in favor of the
terms of this letter. This letter may be executed in one or more counterparts
and each such executed counterpart shall be taken together with all other
executed counterparts and constitutue a single instrument binding upon each such
party hereto and their personal and other legal representatives, heirs,
successors and permitted assigns. The terms of this letter shall be construed,
governed and enforced in accordance with Florida law. The terms of this letter
shall only be effective as of October 19, 2002 if and when it is executed by and
delivered to the Creditor and UltraStrip.

                                                           October __19___, 2001

         ULTRASTRIP SYSTEMS, INC., a Florida corporation with its principal
place of business located at 3515 SE Lionel Terrace, Stuart, Florida
(hereinafter called the "DEBTOR"), for valuable consideration hereby grants to
EUGENE RAINIS, whose address is 290 Mountainside Rd, Mendham, New Jersey 07945
(hereinafter collectively called "SECURED PARTY"), a lien upon and security
interest in the property and any replacements thereof described in Exhibit "A"
attached hereto and by this reference made a part hereof, as well as all
proceeds therefrom and insurance thereon (said property being hereinafter called
the "COLLATERAL").

         This Security Agreement ("AGREEMENT") is entered into to secure the
performance by the DEBTOR of its obligations TO SECURED PARTY as set forth in
the Promissory Note dated _10/19/01___ (hereinafter referred to herein as the
"NOTE"). Incident thereto, the DEBTOR agrees with the SECURED PARTY as follows:

         1.  DEBTOR warrants and represents that:

                  (a) The Security Interest granted to the SECURED PARTY in the
Collateral shall constitute a first lien thereon and no superior lien will be
granted to any other parties as long as a balance remains on this Note, without
the consent of SECURED PARTY, and that DEBTOR is the lawful owner of such
Collateral and has good right to pledge, assign, transfer, and create a Security
Interest in the same;

         2. Upon request and as instructed by SECURED PARTY, the DEBTOR agrees
to comply with the requirements of all valid and applicable state and federal
laws in order to grant to the SECURED PARTY a valid lien upon, and a security
interest in, the Collateral under the Uniform Commercial Code of Florida, or
which may be described in any amendment supplementary hereto.

         3. The DEBTOR will pay, when due, all taxes, assessments, trademark
fees, and other charges lawfully and validly levied or assessed upon the
Collateral or any part thereof, and the DEBTOR will pay any and all fees, costs,
and expenses, of whatever kind and nature, which the SECURED PARTY may incur in
filing public notices.

         4. The DEBTOR agrees to notify the SECURED PARTY promptly of any change
in its mailing address or principal place of business, in order that a prompt
refiling of any outstanding notices may be made, if necessary.

         5. At its option, the SECURED PARTY may discharge taxes, liens, or
security interests or other encumbrances at any time levied or placed on the
Collateral. All such sums, as well as costs, advanced by SECURED PARTY pursuant
to this Security Agreement shall be due immediately from DEBTOR to SECURED
PARTY.

         6. The DEBTOR shall be in default under this Security Agreement upon
the happening of any of the following events or conditions:

                  (a) Failure of DEBTOR to make any payment or perform any
obligation or covenant provided for in this Agreement or the Note;

                  (b) The falsity in any material respect of any warranty,
representation or statement made or furnished to SECURED PARTY by DEBTOR,
expressed in this Agreement or the Definitive Agreement, or necessarily implied
by the provisions hereof;

                  (c) The occurrence of any event which causes the acceleration
of the indebtedness of DEBTOR to others under any indenture, agreement or
undertaking;

                  (d) The making of any levy on, or seizure or allotment of the
Collateral, or any portion thereof;

                  (e)  The dissolution of DEBTOR;

                  (f) Commencement of any voluntary or involuntary proceeding
under the bankruptcy or any state insolvency law against DEBTOR; the
dissolution, insolvency or business failure of DEBTOR; the appointment of a
receiver for any part of the property of Debtor; or the assignment for the
benefit of creditors of DEBTOR; and

         7. Upon such default, and at any time thereafter, the SECURED PARTY may
declare all Obligations secured hereby immediately due and payable, including,
without limitation, all amounts owned under the Promissory Note and shall have
the remedies of a secured party under the Uniform Commercial Code as adopted in
Florida.

         In case of the exercise of any of the rights of the SECURED PARTY
hereunder, all Collateral, and other property or security given to secure the
indebtedness secured hereby, may be offered for sale for one total price, and
the proceeds of such sale accounted for in one account without distinction
between items of security or without assigning to them any proportion of the
proceeds of such sale, the DEBTOR, insofar as it legally may so do, hereby
waiving the application of any doctrine of marshaling, or the Collateral, or
such other property or security, may be offered for sale separately, and sales
may be held from time to time, and all powers of the SECURED PARTY shall not be
fully executed until all Collateral, and such other property or security, shall
have been sold.

          8. No waiver by the SECURED PARTY of any default shall operate as a
waiver of any other default or of the same default on a future occasion. All
rights of the SECURED PARTY hereunder shall inure to the benefit of its
successors and assigns; and all obligations of the DEBTOR shall bind its
successors and assigns.

         9. The covenants and agreements herein contained shall extend to, inure
to the benefit of, and be binding upon, the respective successors, heirs,
executors, administrators, and assigns of the Parties hereto, the same as if
they were in every case named and expressed.

<PAGE>

         10. This Agreement may be executed in one or more counterparts having
the signatures of the parties, and each such counterpart shall, for all
purposes, be deemed an original, but all such counterparts shall together
constitute but one and the same instrument.

         11. Paragraph and Section titles or captions contained in this
Agreement are inserted only as a matter of convenience for reference and in no
way define, limit, extend or describe the scope of this Agreement or the intent
of any provision hereof.

         12. This Agreement represents the entire understanding and agreement
between the Parties with respect to the subject matter hereof, and supersedes
all other negotiations, understandings and representations (if any) made by and
between such Parties.

         13. Any notice required to be given hereunder may be hand delivered,
sent by overnight courier which provides receipts, or by certified mail, return
receipt requested, to the addresses contained in this Agreement or at any other
address as designated in writing by that party. The notice shall be deemed
delivered when received (if hand delivered), on the day following deposit with
the express courier (if forwarded by overnight courier), or on the date of
actual delivery as evidenced by the return receipt, the date delivery is refused
or the date the notice is designated as not deliverable by the postal
authorities, (if sent by certified mail).

         14. This Agreement and all transactions contemplated in this Agreement
shall be governed by, construed and enforced in accordance with, the internal
laws of the State of Florida without regard to principles of conflicts of law.

         15. If any provision of this Agreement or any other agreement entered
into pursuant hereto is contrary to, prohibited by or deemed invalid under
applicable law or regulation, such provision shall be inapplicable and deemed
omitted to the extent so contrary, prohibited or invalid, but the remainder
hereof shall not be invalidated thereby and shall be given full force and effect
so far as possible. If any provisions of this Agreement may be construed in two
or more ways, one of which would render the provision invalid or otherwise
voidable or unenforceable and another of which would render the provision valid
and enforceable, such provision shall have the meaning which renders it valid
and enforceable.

         16. Wherever the construction so requires in this Agreement, the
masculine shall include the feminine and the neuter, and the singular shall
include the plural, and conversely.

         17. The Parties hereby agree from time to time to execute and deliver
such further and other transfers, assignments and documents and do all matters
and things which may be convenient or necessary to more effectively and
completely carry out the intentions of this Agreement.

         18. All covenants, agreements, representations and warranties made
herein or otherwise made in writing by any party pursuant hereto shall survive
the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby.

<PAGE>

         19. The provisions of this Agreement may be amended, supplemented,
waiver or changed orally, only by a writing signed by the party as to whom
enforcement of any such amendment, supplement, waiver or modification is sought
and making specific reference to this Agreement.

         20. Except as otherwise expressly provided herein, no remedy herein
conferred upon any party is intended to be exclusive of any other remedy, and
each and every such remedy shall be cumulative and shall be in addition to every
other remedy given hereunder or now or hereafter existing at law or in equity or
by statute or otherwise. No single or partial exercise by any party of any
right, power or remedy hereunder shall preclude any other or further exercise
thereof.

         IN WITNESS WHEREOF, the DEBTOR has caused this Security Agreement to be
duly executed on its behalf, under seal, as of the day and year first above
written.
