                                 PROMISSORY NOTE

$105,000.00                                                    FEBRUARY 21, 2005

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 JACQUELINE MCGUIRE, ("Lender"; Lenders and each
and all subsequent holders of this note are included in the terms "Holder"), at
3231 SE St. Lucie Blvd., Stuart, FL 34996 (or at such other place as the Holder
hereof may designate), the sum of ONE HUNDRED FIVE THOUSAND AND 00/100 DOLLARS
($105,000.00) with interest at the Applicable Interest Rate, as defined below.
Interest on principal will accrue at the Applicable Interest Rate from February
21, 2005 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 note is due in three annual installments of $35,000 plus
                interest beginning on February 21, 2006 and all remaining
                interest and principal, if any, being due and payable on
                February 21, 2008 (the "Maturity Date").

        b.      The "Applicable Interest Rate" shall be five percent (5%) per
                annum.

        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) 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)
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
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,

<PAGE>

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.

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
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 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,

                                       2

<PAGE>

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.

 THE OBLIGOR AND, BY ITS ACCEPTANCE HEREOF, THE HOLDER, EACH HEREBY WAIVES (1)
ALL RIGHTS TO RELY ON OR ENFORCE ANY ORAL STATEMENTS MADE PRIOR TO,
CONTEMPORANEOUSLY WITH OR SUBSEQUENT TO THE SIGNING OF THIS PROMISSORY NOTE; AND
(2) THE RIGHT EITHER MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY LITIGATION
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.

      Subject to the terms and conditions of this Promissory Note (this "Note"),
for value received, the undersigned ISI Merger Corp. ("Merger Sub"), a Delaware
corporation with an address of 100 Eagle Rock Avenue, East Hanover, New Jersey
07936, hereby promises to pay to ADAM HOCK, an individual residing at 630 First

"Holder"), the principal amount of One Hundred Seventy Seven Thousand Nine
Hundred Thirty Seven Dollars ($177,937) as provided herein.

      This Note is issued and delivered pursuant to the Agreement and Plan of
Merger, dated as of July 28, 2005 (the "Merger Agreement"), by and among
Conversion Services International, Inc. ("CSI"), Merger Sub, Integrated
Strategies, Inc. ("ISI"), ISI Consulting, LLC ("LLC") and Holder. The following
is a statement of the rights of the Holder of this Note and the terms and
conditions to which this Note is subject, and to which the Holder, by acceptance
of this Note, agrees:

      1. Principal Repayment. The payment of the principal of this Note is
contingent upon the actual receipt by Merger Sub of collection receipts from the
Acquired Accounts Receivable (as hereinafter defined), less any and all
out-of-pocket expenses incurred by Merger Sub with respect to such collections.
As used herein, "Acquired Accounts Receivable" shall mean the accounts
receivable of ISI and LLC acquired by Merger Sub at the closing of the
transactions contemplated by the Merger Agreement. The Holder shall not be paid
on any Acquired Accounts Receivable due under this Note until $352,063 of the
Acquired Accounts Receivable have been first collected by Merger Sub or CSI.

      2. Interest. This Note shall be non-interest bearing.

      3. Maturity. Provided that the condition set forth in Section 1
hereinabove is satisfied, the principal of this Note shall be due and payable by
5:00 PM Eastern Standard Time on the seventh (7th) business day following the
day that Merger Sub actually receives a collection receipt from an Acquired
Accounts Receivable (the "Payment Period"). In the event that the an Acquired
Accounts Receivable is collected by Merger Sub and not paid as payment on this
Note within the Payment Period, the Holder shall have the opportunity to claim a
default for the amount due. Merger Sub shall have the opportunity to cure this
default within three (3) business days of receipt of a default notice (the "Cure
Period") from Holder and make the requisite payment in full. If payment in full
has not been made to the Holder by the end of the Cure Period, the Holder shall
receive a consent judgment for the Acquired Accounts Receivable collected by
Merger Sub due. In the event that payment has been made during the Cure Period,
there shall be no consent judgment for the Holder. In the event a consent
judgment is received at any time, any subsequent judgment(s) received in
accordance with the above payment terms shall be for the entire outstanding
balance of this Note.

      4. Payment. All payments with respect to this Note shall be made in lawful
money of the United States of America at such place as the Holder hereof may
reasonably designate in writing to Merger Sub.

      5. No Security. This Note is unsecured.

      6. Mutilated, Destroyed, Lost or Stolen Note. In case this Note shall
become mutilated or defaced, or be destroyed, lost or stolen, Merger Sub shall
execute and deliver a new note of like principal amount in exchange and
substitution for the mutilated or defaced Note, or in lieu of and in
substitution for the destroyed, lost or stolen Note. In the case of a mutilated
or defaced Note, the Holder shall surrender such Note to Merger Sub. In the case
of any destroyed, lost or stolen Note, the Holder shall furnish to Merger Sub:
(a) evidence to its satisfaction of the destruction, loss or theft of such Note,
and (b) such security or indemnity as may be reasonably required by Merger Sub
to hold Merger Sub harmless.

      7. Assignment. The rights and obligations of Merger Sub and the Holder of
this Note shall be binding upon, and inure to the benefit of, their permitted

without the prior written consent of Merger Sub. Payment under this Note shall
be made only to the registered holder of this Note.

      8. Waiver and Amendment. Any provision of this Note, including, without
limitation, the due date hereof, and the observance of any term hereof, may be
