      RE: EXTENSION OF MATURITY OF NOTE AND MODIFICATION OF NOTE,
          SECURITY AGREEMENT AND OF SUBSCRIPTION AND WARRANT PURCHASE AGREEMENT

Dear Mr. Johnson:

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

         On December 9, 2002, UltraStrip executed a Promissory Note in the
amount of $118,650.00 and a Subscription and Warrant Purchase Agreement of even
date therewith. On December 9, 2002, the Creditor, Eugene Rainis, paid an
additional $6,350 pursuant to the Warrant Agreement.

         The original $862,069.00 Senior Promissory Note was extended in several
steps, such that it ultimately matured on September 15, 2003 in the amount of
$1,000,000.00. Similarly, the $118,650 Promissory Note was extended in several
steps, such that it ultimately matured on September 7, 2003 in the amount of
$125,000.00. UltraStrip and the Creditor hereby agree to combine those two
Promissory Notes in the amount of $1,125,000.00. This single Promissory Note
will mature on March 15, 2004.

         In lieu of cash interest, the Creditor agreed to accept 20 year
duration warrants for the purchase of UltraStrip Common Stock. In consideration
for the original $862,069.00 loan and the numerous extensions thereof, a total
of 422,500 warrants were issued. In consideration for the original $118,650 loan
and the numerous extensions thereof, a total of 40,000 warrants were issued.
Now, in consideration for the Creditor's agreement to combine the Promissory

<PAGE>

Notes and to extend the maturity date of the combined Senior Promissory Note
until March 15, 2004, UltraStrip hereby agrees to issue to the Creditor an
additional 195,000 warrants with expiration dates of March 15, 2004 and strike
prices of $0.07. Each warrant entitles the holder to purchase one share of
UltraStrip Common Stock.

         In addition the 195,000 warrants referenced above, UltraStrip Systems,
Inc. hereby agrees to issue to the creditor 40,000 warrants with expirations
dates of March 15, 2024 and strike prices of $1.02. Each warrant entitles the
holder to purchase one share of UltraStrip Common Stock.

         At UltraStrip's option, the Promissory Note may be extended on a
month-by-month basis until September 14, 2004. For each month that UltraStrip
extends the Promissory Note, UltraStrip will issue to the creditor 32,500
warrants with strike prices of $.07 and expiration dates of March 15, 2024. Each
warrant entitles the holder to purchase one share of UltraStrip Common Stock.
Additionally, for each month that UltraStrip extends the Promissory Note,
UltraStrip will issue the creditor 6,667 warrants with strike prices of $1.02
and expiration dates of March 15, 2024. Each warrant entitles the holder to
purchase one share of UltraStrip Common Stock.

         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, Security Agreement and/or Warrant
Agreement other than the failure to pay the Initial Advances as of September 15
and September 7, 2003, which dates have been extended as provided herein, (b)
the Note, Security Agreement and Warrant Agreement remain in full force and
effect except as otherwise amended as provided herein, and (c) UltraStrip 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, Security
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 constitute a single instrument binding upon each such party
hereto and their personal and other legal representatives, heirs, successors and

enforced in accordance with Florida law. The terms of this letter shall only be
effective as of February 12, 2004, if and when it is executed by, and delivered
to, the Creditor and UltraStrip.

Sincerely,                                           Accepted by:

         hereinafter set forth, and intending to be legally bound hereby, the
         parties hereto agree as follows:

                                    ARTICLE I
                         REPRESENTATIONS AND WARRANTIES

         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.

                                       2
<PAGE>

                  (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.

                  (g) The Purchaser has full right and power to perform pursuant
to this 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.

                  (h) The Purchaser fully understands that the Warrants and/or
Shares 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
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.

$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

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

                                   ARTICLE II
                          SALE AND PURCHASE OF WARRANTS

         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.

         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.

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

in any document provided by the Purchaser to the Corporation.
