                                ESCROW AGREEMENT
                                ----------------

     THIS ESCROW AGREEMENT  ("Agreement") is made as of December 18, 2001 by and
between Jacobson Resonance Enterprises, Inc. Resonance Enterprises, Inc. (the
"Company"), TECINVEST SERVICES, INC. (the "Investor") and Joseph B. LaRocco,
Esq., with an office at 49 Locust Avenue, Suite 107, New Canaan, CT 06840 (the
"Escrow Agent").

                              W I T N E S S E T H:

     WHEREAS, Company will be selling shares of its common stock (the "Shares"),
to Investor upon terms as set forth in the Investment Agreement and related
documents (the "Transaction Documents") entered into by the Company and
Investor; and

     WHEREAS, Company and Investor have requested that the Escrow Agent hold the
Shares and funds ("Funds") being used to purchase the Shares in escrow pursuant
to the terms of this Agreement.

     NOW,  THEREFORE,  in  consideration  of the covenants  and mutual  promises
contained herein and other good and valuable consideration, the receipt and
legal sufficiency of which are hereby acknowledged and intending to be legally
bound hereby, the parties agree as follows:

                                    ARTICLE 1
                                    ---------
                               TERMS OF THE ESCROW

     1.1 The parties hereby agree to have Joseph B. LaRocco, Esq. act as Escrow
Agent whereby the Escrow Agent shall receive the Shares and Funds in escrow and
distribute the same as set forth in this Agreement. Any capitalized terms not
defined herein shall have the meaning ascribed to them in the Transaction
Documents.

     1.2 Prior to each Put Notice Date, (i) the Company shall deliver to the
Escrow Agent certificates representing the Shares to be issued to the Investor
or deposit such Shares into the account(s) (with the Investor receiving
confirmation that the Shares are in such account(s)) designated by the Investor
for the benefit of the Investor and (ii) the Investor shall deliver to the
Escrow Agent the Purchase Price to be paid for such Shares (after receipt of
confirmation of delivery of such Shares), determined as aforesaid, by wire
transfer. In the alternative to physical delivery of certificates for Common
Stock to the Escrow Agent, if delivery of the Shares may be effectuated by
electronic book-entry through The Depository Trust Company ("DTC"), then
delivery of the Shares pursuant to such purchase shall, unless requested
otherwise by such Investor, settle by book-entry transfer through DTC by the Put
Notice Date. The parties agree to coordinate with DTC to accomplish this
objective. In addition, each of the Company and the Investor shall deliver all
documents, instruments and writings required to be delivered by either of them
to the Escrow Agent pursuant to the Investment Agreement at or prior to each
Closing.

     The number of Shares to be delivered to the Escrow Agent shall be the
result of the following formula:

                                 Purchase Amount
                                 ---------------
                                 Purchase Price

     1.3 Prior to each Closing Date the Investor  shall wire to the Escrow Agent
that amount necessary to purchase the Shares on the Closing Date as required by
the Transaction Documents (the "Purchase Amount").

     1.4 On each Closing Date the Escrow Agent shall forward the Shares being
purchased to the Investor, per Investor's written instructions, and wire the
amount necessary to purchase the Shares, pursuant to the Transaction Documents,
to the Company, per the Company's written instructions. Subject to the terms set
forth in the Transaction Documents, the Investor is required to purchase the
lesser of (a) the Dollar Amount set forth in the Put Notice and (b) 15% of the
total Average Daily Equity Traded during the applicable Purchase Period. The
Escrow Agent shall deduct from the Funds he receives in escrow from the Investor
the following amounts:

     (a)  On each Closing Date Escrow Agent shall deduct from the Purchase
          Amount as an escrow fee the sum of $500 for each Put Notice which
          amount the Escrow Agent may deduct from the proceeds received in
          escrow from the Investor;

     1.5 After Investor's receipt of a Put Notice, but prior to the related
Closing Date, the Investor may authorize the Escrow Agent to release a portion
of the Purchase Amount from escrow to the Company in exchange for a fixed number
of Shares, subject to the following conditions:

     (a)  The Investor shall fill out and sign a "Partial Release of Purchase
          Amount and Shares from Escrow" (the "Partial Release Form").  See
          Exhibit A attached hereto. The Partial Release Form shall set forth
          the number of Shares to be released to Investor and the dollar amount
          the Escrow Agent shall wire to the Company.

     (b)  The Partial Release Form shall be filled out and signed by the
          Investor and faxed to the Company and the Escrow Agent prior to 12:00
          p.m. New York City time.

     The number of Shares stated in the Partial Release Form shall be equal to
the dollar amount to be released divided by 85% of the average of the four (4)
lowest closing bid prices during that number of Trading Days in the Purchase
Period that have expired, but if less than four (4) Trading Days have expired
prior to receipt by the Company of the Partial Release Form, then the lowest
closing bid price for that number of days shall be used.

     The Company and Investor agree that on the related closing date, an
adjustment shall be made so that the terms set forth in the Investment Agreement
shall be honored with the balance of the Purchase Price being released to the
Company and the balance of Shares owed to Investor being released to Investor.

     1.6 If the Escrow Agent does not have the exact number of Shares to send
Investor, because of the denominations of the various Share certificates, the
parties will mutually agree on how to resolve the matter.

     1.7 This Agreement may be altered or amended only with the written consent
of all of the parties hereto. Should Company attempt to change this Agreement in
a manner which, in the Escrow Agent's discretion, shall be undesirable, the
Escrow Agent may resign as Escrow Agent by notifying Company and Investor in
writing. In the case of the Escrow Agent's resignation or removal pursuant to
the foregoing, his only duty, until receipt of notice from Company and Investor
that a successor escrow agent has been appointed, shall be to hold and preserve
the Shares and Funds that are in his possession. Upon receipt by the Escrow
Agent of said notice from Company and Investor of the appointment of a successor
escrow agent, the name of a successor escrow account and a direction to transfer
the Shares and Funds, the Escrow Agent shall promptly thereafter transfer all of
the Shares and Funds that he is still holding in escrow, to said successor
escrow agent. Immediately after said transfer of the Shares and Funds, the
Escrow Agent shall furnish Company and Investor with proof of such transfer. The
Escrow Agent is authorized to disregard any notices, requests, instructions or
demands received by it from Company or Investor after notice of resignation or
removal has been given.

     1.8 The Escrow Agent shall be reimbursed by Company and Investor for any
reasonable expenses incurred in the event there is a conflict between the
parties and the Escrow Agent shall deem it necessary to retain counsel, upon
whose advice the Escrow Agent may rely. The Escrow Agent shall not be liable for
any action taken or omitted by him in good faith and in no event shall the
Escrow Agent be liable or responsible except for the Escrow Agent's own gross
negligence or willful misconduct. The Escrow Agent has made no representations
or warranties to the Company in connection with this transaction. The Escrow
Agent has no liability hereunder to either party other than to hold the Shares
and Funds received by the Investor and to deliver them under the terms hereof.
Each party hereto agrees to indemnify and hold harmless the Escrow Agent from
and with respect to any suits, claims, actions or liabilities arising in any way
out of this transaction including the obligation to defend any legal action
brought which in any way arises out of or is related to this Agreement or the
investment being made by Investor. The Company acknowledges and represents that
it is not being represented in a legal capacity by Joseph B. LaRocco, and has
had the opportunity to consult with its own legal advisors prior to the signing
of this Agreement. The Company acknowledges that the Escrow Agent is not
rendering securities advice to the Company with respect to this proposed
transaction. The Escrow Agent has acted as legal counsel for the Investor and
may continue to act as legal counsel for the Investor, from time to time,
notwithstanding its duties as the Escrow Agent hereunder. The Company consents
to the Escrow Agent acting in such capacity as legal counsel for the Investor
and waives any claim that such representation represents a conflict of interest
on the part of the Escrow Agent. The Company understands that the Investor and
Escrow Agent are relying explicitly on the foregoing provisions contained in
this Section 1.8 in entering into this Agreement.

     1.9 The Escrow Agent shall be obligated only for the performance of such
duties as are specifically set forth herein and may rely and shall be protected
in relying or refraining from acting on any instrument reasonably believed by
the Escrow Agent to be genuine and to have been signed or presented by the
proper party or parties. The Escrow Agent shall not be personally liable for any
act the Escrow Agent may do or omit to do hereunder as the Escrow Agent while
acting in good faith, and any act done or omitted by the Escrow Agent pursuant
to the advice of the Escrow Agent's attorneys-at-law shall be conclusive
evidence of such good faith.

     1.10 The Escrow Agent is hereby expressly authorized to disregard any and
all warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Escrow Agent obeys or complies with any such order, judgment
or decree, the Escrow Agent shall not be liable to any of the parties hereto or
to any other person, firm or corporation by reason of such decree being
subsequently reversed, modified, annulled, set aside, vacated or found to have
been entered without jurisdiction.

     1.11 The Escrow Agent shall not be liable in any respect on account of the
identity, authorities or rights of the parties executing or delivering or
purporting to execute or deliver the Agreement or any documents or papers
deposited or called for hereunder.

     1.12 If the Escrow Agent reasonably requires other or further documents in
connection with this Agreement, the necessary parties hereto shall join in
furnishing such documents.

     1.13 It is understood and agreed that should any dispute arise with respect
to the delivery and/or ownership or right of possession of the documents or the
Funds held by the Escrow Agent hereunder, the Escrow Agent is authorized and
directed in the Escrow Agent's sole discretion (a) to retain in the Escrow
Agent's possession without liability to anyone all or any part of said documents
or the Funds until such disputes shall have been settled either by mutual
written agreement of the parties concerned or by a final order, decree or
judgment of a court of competent jurisdiction after the time for appeal has
expired and no appeal has been perfected, but the Escrow Agent shall be under no
duty whatsoever to institute or defend any such proceedings or (b) to deliver
the Funds and any other property and documents held by the Escrow Agent
hereunder to a state or federal court having competent subject matter
jurisdiction and located in the State of Connecticut in accordance with the
applicable procedure therefor.

                                    ARTICLE 2
                                    ---------
                                  MISCELLANEOUS

     2.1 No waiver of any breach of any covenant or provision herein contained
shall be deemed a waiver of any preceding or succeeding breach thereof, or of
any other covenant or provision herein contained. No extension of time for
performance of any obligation or act shall be deemed any extension of the time
for performance of any other obligation or act.

     2.2 This Agreement shall not be binding assignable.

     2.3 This Agreement is the final expression of, and contains the entire
agreement between, the parties with respect to the subject matter hereof and
supersedes all prior understandings with respect thereto. This Agreement may not
be modified, changed, supplemented or terminated, nor may any obligations
hereunder be waived, except by written instrument signed by the parties to be
charged or by its agent duly authorized in writing or as otherwise expressly
permitted herein.

     2.4 Whenever required by the context of this Agreement, the singular shall
include the plural and masculine shall include the feminine. This Agreement may
be executed in two or more counterparts, all of which taken together shall
constitute one instrument. Execution and delivery of this Agreement by exchange
of facsimile copies bearing the facsimile signature of a party shall constitute
a valid and binding execution and delivery of this Agreement by such party. Such
facsimile copies shall constitute enforceable original documents.

     2.5 The parties hereto expressly agree that this Agreement shall be
governed by, interpreted under, and construed and enforced in accordance of the
laws of the State of Florida. The parties agree that any dispute arising under
or with respect to or in connection with this Agreement, whether during the term
of this Agreement or at any subsequent time, shall be resolved fully and
exclusively by binding arbitration in accordance with the commercial rules then
in force of the American Arbitration Association with the proceedings taking
place in West Palm Beach, Florida before a panel of three (3) arbitrators.

     2.6 Any notice required or permitted hereunder shall be given in manner
provided in the Section headed "NOTICES" in the Transaction Documents, the terms
of which are incorporated herein by reference.

     2.7 By signing this Agreement, the Escrow Agent becomes a party hereto only
for the purpose of this Agreement; the Escrow Agent does not become a party to
the Transaction Documents.

     2.8 Each party acknowledges and agrees that this Agreement shall not be
deemed prepared or drafted by any one party. In the event of any dispute between
the parties concerning this Agreement, the parties agree that any rule of
construction, to the effect that any ambiguity in the language of the Agreement
is to be resolved against the drafting party, shall not apply.

                [Balance of this page intentionally left blank.]

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the 18th day of December 2001.

     FOR VALUE RECEIVED, JACOBSON RESONANCE ENTERPRISES, INC. a Nevada
corporation (the "Company"), hereby promises to pay TECINVEST SERVICES, INC.
(the "Holder") on December 18, 2004, (the "Maturity Date"), the principal amount
of Seventy-five Thousand Dollars ($75,000) U.S., and to pay interest on the
principal amount hereof, in such amounts, at such times and on such terms and
conditions as are specified herein.

Article 1. Interest

     The Company shall pay interest on the unpaid principal amount of this
Debenture (the "Debenture") at the time of each conversion until the principal
amount hereof is paid in full or has been converted. The Debentures shall pay
six percent (6%) cumulative interest, in cash or in shares of common stock, par
value $.001 per share, of the Company ("Common Stock"), at the Company's option,
at the time of each conversion. The closing shall be deemed to have occurred on
the date the funds are received by the Company (the "Closing Date"). If the
interest is to be paid in cash, the Company shall make such payment within five
(5) business days of the date of conversion. If the interest is to be paid in
Common Stock, said Common Stock shall be delivered to the Holder, or per
Holder's instructions, within five (5) business days of the date of conversion.
The Debentures are subject to automatic conversion at the end of three (3) years
from the date of issuance at which time all Debentures outstanding will be
automatically converted based upon the formula set forth in Section 3.2.

Article 2. Method of Payment

     This Debenture must be surrendered to the Company in order for the Holder
to receive payment of the principal amount hereof. The Company shall have the
option of paying the interest on this Debenture in United States dollars or in
Common Stock upon conversion pursuant to Article 1 hereof. The Company may draw
a check for the payment of interest to the order of the Holder of this Debenture
and mail it to the Holder's address as shown on the Register (as defined in
Section 7.2 below). Interest and principal payments shall be subject to
withholding under applicable United States Federal Internal Revenue Service
Regulations.

Article 3.  Conversion

     Section 3.1. Conversion Privilege

     (a) The  Holder of this Debenture shall have the right to convert it into
shares of Common Stock at any time following the Closing Date and which is
before the close of business on the Maturity Date, except as set forth in
Section 3.1(c) below. The number of shares of Common Stock issuable upon the
conversion of this Debenture is determined pursuant to Section 3.2 and rounding
the result to the nearest whole share.

     (b)  Less than all of the principal amount of this Debenture may be
converted into Common Stock if the portion converted is $5,000 or a whole
multiple of $5,000 and the provisions of this Article 3 that apply to the
conversion of all of the Debenture shall also apply to the conversion of a
portion of it. This Debenture may not be converted, whether in whole or in part,
except in accordance with Article 3.

     (c) In the event all or any portion of this Debenture remains outstanding
on the Maturity Date, the unconverted portion of such Debenture will
automatically be converted into shares of Common Stock on such date in the
manner set forth in Section 3.2.

     Section 3.2. Conversion Procedure.

     (a) Debentures. Upon receipt by the Company or its designated attorney of a
facsimile or original of Holder's signed Notice of Conversion (See Exhibit A
attached hereto) preceded by, together with or followed by receipt of the
original Debenture to be converted in whole or in part in the manner set forth
in 3.2(b) below, the Company shall instruct its transfer agent to issue one or
more Certificates representing that number of shares of Common Stock into which
the Debenture is convertible. The Company shall act as Registrar and shall
maintain an appropriate ledger containing the necessary information with respect
to each Debenture.

     (b)  Conversion Procedures.  The face amount of this Debenture may be
converted, in whole or in part, anytime following the Closing Date. Such
conversion shall be effectuated by surrendering to the Company, or its attorney,
this Debenture to be converted together with a facsimile or original of the
signed Notice of Conversion which evidences Holder's intention to convert the
Debenture indicated. The date on which the Notice of Conversion is effective
("Conversion Date") shall be deemed to be the date on which the Holder has
delivered to the Company a facsimile or original of the signed Notice of
Conversion, as long as the original Debenture(s) to be converted are received by
the Company within three (3) business days thereafter. Notwithstanding the
above, any Notice of Conversion not received by 5:00 P.M. EST, shall be deemed
to have been received the next business day.

     (c) Common Stock to be Issued.  Upon the conversion of any Debentures and
upon receipt by the Company or its attorney of a facsimile or original of
Holder's signed Notice of Conversion the Company shall instruct its transfer
agent to issue stock certificates without restrictive legend or stop transfer
instructions, if at that time the Registration Statement has been deemed
effective (or with proper restrictive legend if the Registration Statement has
not as yet been declared effective), in such denominations to be specified at
conversion representing the number of shares of Common Stock issuable upon such
conversion, as applicable. The Company warrants that no instructions, other than
these instructions, have been given or will be given to the transfer agent and
that the Common Stock shall otherwise be freely resold, except as may be set
forth herein.

     (d) Conversion Rate.  Holder is entitled to convert the face amount of this
Debenture, plus accrued interest, anytime following the Closing Date, at the
lesser of (i) one hundred ten percent (110%) of the average closing bid price
for the five (5) trading dys immediately preceding the Closing Date or (ii)
seventy-five percent (75%) of the average of the six (6) lowest closing bid
prices during the twenty (20) trading days prior to conversion, each being
referred to as the "Conversion Price". No fractional shares or scrip
representing fractions of shares will be issued on conversion, but the number of
shares issuable shall be rounded up or down, as the case may be, to the nearest
whole share.

     (e) Nothing contained in this Debenture shall be deemed to establish or
require the payment of interest to the Holder at a rate in excess of the maximum
rate permitted by governing law. In the event that the rate of interest required
to be paid exceeds the maximum rate permitted by governing law, the rate of
interest required to be paid thereunder shall be automatically reduced to the
maximum rate permitted under the governing law and such excess shall be returned
with reasonable promptness by the Holder to the Company.

     (f) It shall be the Company's responsibility to take all necessary actions
and to bear all such costs to issue the Common Stock as provided herein,
including the responsibility and cost for delivery of an opinion letter to the
transfer agent, if so required. The person in whose name the certificate of
Common Stock is to be registered shall be treated as a shareholder of record on
and after the conversion date. Upon surrender of any Debentures that are to be
converted in part, the Company shall issue to the Holder a new Debenture equal
to the unconverted amount, if so requested in writing by Holder.

     (g)  Within five (5) business days after receipt of the documentation
referred to above in Section 3.2(b), the Company shall deliver a certificate, in
accordance with Section 3.2(c) for the number of shares of Common Stock issuable
upon the conversion. In the event the Company does not make delivery of the
Common Stock, as instructed by Holder, within five (5) business days after the
Conversion Date, then in such event the Company shall pay to Holder one percent
(1%) in cash, of the dollar value of the Debentures being converted per each day
after the fifth (5th) business day following the Conversion Date that the Common
Stock is not delivered to the Purchaser.
     The Company acknowledges that its failure to deliver the Common Stock
within five (5) business days after the Conversion Date will cause the Holder to
suffer damages in an amount that will be difficult to ascertain. Accordingly,
the parties agree that it is appropriate to include in this Debenture a
provision for liquidated damages. The parties acknowledge and agree that the
liquidated damages provision set forth in this section represents the parties'
good faith effort to quantify such damages and, as such, agree that the form and
amount of such liquidated damages are reasonable and will not constitute a
penalty. The payment of liquidated damages shall not relieve the Company from
its obligations to deliver the Common Stock pursuant to the terms of this
Debenture.
     To the extent that the failure of the Company to issue the Common Stock
pursuant to this Section 3.2(g) is due to the unavailability of authorized but
unissued shares of Common Stock, the provisions of this Section 3.2(g) shall not
apply but instead the provisions of Section 3.2(h) shall apply. The Company
shall make any payments incurred under this Section 3.2(g) in immediately
available funds within five (5) business days from the date the Common Stock is
fully delivered. Nothing herein shall limit a Holder's right to pursue actual
damages or cancel the conversion for the Company's failure to issue and deliver
Common Stock to the Holder within five (5) business days after the Conversion
Date.

     (h) The Company shall at all times reserve (or make alternative written
arrangements for reservation or contribution of shares) and have available all
Common Stock necessary to meet conversion of the Debentures by all Holders of
the entire amount of Debentures then outstanding. If, at any time Holder submits
a Notice of Conversion and the Company does not have sufficient authorized but
unissued shares of Common Stock (or alternative shares of Common Stock as may be
contributed by Stockholders) available to effect, in full, a conversion of the
Debentures (a "Conversion Default", the date of such default being referred to
herein as the "Conversion Default Date"), the Company shall issue to the Holder
all of the shares of Common Stock which are available, and the Notice of
Conversion as to any Debentures requested to be converted but not converted (the
"Unconverted Debentures"), may be deemed null and void upon written notice sent
by the Holder to the Company. The Company shall provide notice of such
Conversion Default ("Notice of Conversion Default") to all existing Holders of
outstanding Debentures, by facsimile, within three (3) business day of such
default (with the original delivered by overnight or two day courier), and the
Holder shall give notice to the Company by facsimile within five business days
of receipt of the original Notice of Conversion Default (with the original
delivered by overnight or two day courier) of its election to either nullify or
confirm the Notice of Conversion.

     The Company agrees to pay to all Holders of outstanding Debentures payments
for a Conversion Default ("Conversion Default Payments") in the amount of
(N/365) x (.24) x the initial issuance price of the outstanding and/or tendered
but not converted Debentures held by each Holder where N = the number of days
from the Conversion Default Date to the date (the "Authorization Date") that the
Company authorizes a sufficient number of shares of Common Stock to effect
conversion of all remaining Debentures. The Company shall send notice
("Authorization Notice") to each Holder of outstanding Debentures that
additional shares of Common Stock have been authorized, the Authorization Date
and the amount of Holder's accrued Conversion Default Payments. The accrued
Conversion Default shall be paid in cash or shall be convertible into Common
Stock at the Conversion Rate, upon written notice sent by the Holder to the
Company, which Conversion Default shall be payable as follows: (i) in the event
Holder elects to take such payment in cash, cash payments shall be made to such
Holder of outstanding Debentures by the fifth day of the following calendar
month, or (ii) in the event Holder elects to take such payment in stock, the
Holder may convert such payment amount into Common Stock at the conversion rate
set forth in section 3.2(d) at anytime after the 5th day of the calendar month
following the month in which the Authorization Notice was received, until the
expiration of the mandatory two (2) year conversion period.
     The Company acknowledges that its failure to maintain a sufficient number
of authorized but unissued shares of Common Stock to effect in full a conversion
of the Debentures will cause the Holder to suffer damages in an amount that will
be difficult to ascertain. Accordingly, the parties agree that it is appropriate
to include in this Agreement a provision for liquidated damages. The parties
acknowledge and agree that the liquidated damages provision set forth in this
section represents the parties' good faith effort to quantify such damages and,
as such, agree that the form and amount of such liquidated damages are
reasonable and will not constitute a penalty. The payment of liquidated damages
shall not relieve the Company from its obligations to deliver the Common Stock
pursuant to the terms of this Debenture. Nothing herein shall limit the Holder's
right to pursue actual damages for the Company's failure to maintain a
sufficient number of authorized shares of Common Stock.

     (i) If, by the fifth (5th)  business day after the  Conversion  Date of any
portion of the Debentures to be converted (the "Delivery Date"), the transfer
agent fails for any reason to deliver the Common Stock upon conversion by the
Holder and after such Delivery Date, the Holder purchases, in an open market
transaction or otherwise, shares of Common Stock (the "Covering Shares") solely
in order to make delivery in satisfaction of a sale of Common Stock by the
Holder (the "Sold Shares"), which delivery such Holder anticipated to make using
the Common Stock issuable upon conversion (a "Buy-In"), the Company shall pay to
the Holder, in addition to any other amounts due to Holder pursuant to this
Debenture, and not in lieu thereof, the Buy-In Adjustment Amount (as defined
below). The "Buy In Adjustment Amount" is the amount equal to the excess, if
any, of (x) the Holder's total purchase price (including brokerage commissions,
if any) for the Covering Shares over (y) the net proceeds (after brokerage
commissions, if any) received by the Holder from the sale of the Sold Shares.
The Company shall pay the Buy-In Adjustment Amount to the Holder in immediately
available funds within five (5) business days of written demand by the Holder.
By way of illustration and not in limitation of the foregoing, if the Holder
purchases shares of Common Stock having a total purchase price (including
brokerage commissions) of $11,000 to cover a Buy-In with respect to shares of
Common Stock it sold for net proceeds of $10,000, the Buy-In Adjustment Amount
which the Company will be required to pay to the Holder will be $1,000.

     (j) The Company shall furnish to Holder such number of prospectuses and
other documents incidental to the registration of the shares of Common Stock
underlying the Debentures, including any amendment of or supplements thereto.

     (k) Limitation on Issuance of Shares. If the Company's Common Stock becomes
listed on the Nasdaq SmallCap Market after the issuance of the Debentures, the
Company may be limited in the number of shares of Common Stock it may issue by
virtue of (X) the number of authorized shares or (Y) the applicable rules and
regulations of the principal securities market on which the Common Stock is
listed or traded, including, but not necessarily limited to, NASDAQ Rule
4310(c)(25)(H)(i) or Rule 4460(i)(1), as may be applicable (collectively, the
"Cap Regulations"). Without limiting the other provisions thereof, the
Debentures shall provide that (i) the Company will take all steps reasonably
necessary to be in a position to issue shares of Common Stock on conversion of
the Debentures without violating the Cap Regulations and (ii) if, despite taking
such steps, the Company still cannot issue such shares of Common Stock without
violating the Cap Regulations, the holder of a Debenture which cannot be
converted as result of the Cap Regulations (each such Debenture, an "Unconverted
Debenture") shall have the right to elect either of the following remedies:

          (x) if permitted by the Cap Regulations, require the Company to issue
     shares of Common Stock in accordance with such  holder's Notice of
     Conversion at a conversion purchase price equal to the average of the
     closing bid price per share of Common Stock for any five (5) consecutive
     trading days (subject to certain equitable  adjustments for certain events
     occurring during such period) during the sixty (60) trading days
     immediately preceding the Conversion Date; or

          (y) require the Company to redeem each Unconverted Debenture for an
     amount (the "Redemption Amount"), payable in cash, equal to the sum of (i)
     one hundred thirty-three percent (133%) of the principal of an Unconverted
     Debenture, plus (ii) any accrued but unpaid interest thereon through and
     including the date (the "Redemption Date") on which the Redemption Amount
     is paid to the holder.

     A holder of an Unconverted Debenture may elect one of the above remedies
with respect to a portion of such Unconverted Debenture and the other remedy
with respect to other portions of the Unconverted Debenture. The Debentures
shall contain provisions substantially consistent with the above terms, with
such additional provisions as may be consented to by the Holder. The provisions
of this section are not intended to limit the scope of the provisions otherwise
included in the Debentures.

     (l)  Limitation on Amount of Conversion and Ownership.  Notwithstanding
anything to the contrary in this Debenture, in no event shall the Holder be
entitled to convert that amount of Debenture, and in no event shall the Company
permit that amount of conversion, into that number of shares, which when added
to the sum of the number of shares of Common Stock beneficially owned, (as such
term is defined under Section 13(d) and Rule 13d-3 of the Securities Exchange
Act of 1934, as may be amended, (the "1934 Act")), by the Holder, would exceed
4.99% of the number of shares of Common Stock outstanding on the Conversion
Date, as determined in accordance with Rule 13d-1(j) of the 1934 Act. In the
event that the number of shares of Common Stock outstanding as determined in
accordance with Section 13(d) of the 1934 Act is different on any Conversion
Date than it was on the Closing Date, then the number of shares of Common Stock
outstanding on such Conversion Date shall govern for purposes of determining
whether the Holder would be acquiring beneficial ownership of more than 4.99% of
the number of shares of Common Stock outstanding on such Conversion Date.

     (m) Legend. The Holder acknowledges that each certificate representing the
Debentures, and the Common Stock unless registered pursuant to the Registration
Rights Agreement, shall be stamped or otherwise imprinted with a legend
substantially in the following form:

     THE SECURITIES EVIDENCED BY THIS CERTIFICATE MAY NOT BE OFFERED OR SOLD,
     TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT (i)
     PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF
     1933, AS AMENDED, (ii) TO THE EXTENT APPLICABLE, RULE 144 UNDER THE ACT (OR
     ANY SIMILAR RULE UNDER SUCH ACT RELATING TO THE DISPOSITION OF SECURITIES),
     OR (iii) IF AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE.

     (n) Prior to conversion of all the Debentures and exercise of all the
Warrants, if at anytime the conversion of all the Debentures and exercise of all
the Warrants outstanding would result in an insufficient number of authorized
shares of Common Stock being available to cover all the conversions, then in
such event, the Company will move to call and hold a shareholder's meeting or
have shareholder action with written consent of the proper number of
shareholders within thirty (30) days of such event, or such greater period of
time if statutorily required or reasonably necessary as regards standard
brokerage house and/or SEC requirements and/or procedures, for the purpose of
authorizing additional shares of Common Stock to facilitate the conversions. In
such an event management of the Company shall recommend to all shareholders to
vote their shares in favor of increasing the authorized number of shares of
Common Stock. Management of the Company shall vote all of its shares of Common
Stock in favor of increasing the number of shares of authorized Common Stock.
Company represents and warrants that under no circumstances will it deny or
prevent Holder's right to convert the Debentures as permitted under the terms of
this Subscription Agreement or the Registration Rights Agreement. Nothing in
this Section shall limit the obligation of the Company to make the payments set
forth in Section 3.2(g). In the event the Company's shareholder's meeting does
not result in the necessary authorization, the Company shall redeem the
outstanding Debentures for an amount equal to (x) the sum of the principal of
the outstanding Debentures plus accrued interest thereon multiplied by (y) 133%.

     Section 3.3.  Fractional Shares.  The Company shall not issue fractional
shares of Common Stock, or scrip representing fractions of such shares, upon the
conversion of this Debenture. Instead, the Company shall round up or down, as
the case may be, to the nearest whole share.

     Section 3.4.  Taxes on Conversion.  The Company shall pay any documentary,
stamp or similar issue or transfer tax due on the issue of shares of Common
Stock upon the conversion of this Debenture. However, the Holder shall pay any
such tax which is due because the shares are issued in a name other than its
name.

     Section 3.5. Company to Reserve Stock. The Company shall reserve the number
of shares of Common Stock required pursuant to and upon the terms set forth in
the Subscription Agreement to permit the conversion of this Debenture. All
shares of Common Stock which may be issued upon the conversion hereof shall upon
issuance be validly issued, fully paid and nonassessable and free from all
taxes, liens and charges with respect to the issuance thereof.

     Section 3.6.  Restrictions on Sale. This Debenture has not been registered
under the Securities Act of 1933, as amended, (the "Act") and is being issued
under Section 4(2) of the Act and Rule 506 of Regulation D promulgated under the
Act. This Debenture and the Common Stock issuable upon the conversion thereof
may only be sold pursuant to registration under or an exemption from the Act.

     Section 3.7.  Mergers, Etc. If the Company merges or consolidates with
another corporation or sells or transfers all or substantially all of its assets
to another person and the holders of the Common Stock are entitled to receive
stock, securities or property in respect of or in exchange for Common Stock,
then as a condition of such merger, consolidation, sale or transfer, the Company
and any such successor, purchaser or transferee shall amend this Debenture to
provide that it may thereafter be converted on the terms and subject to the
conditions set forth above into the kind and amount of stock, securities or
property receivable upon such merger, consolidation, sale or transfer by a
holder of the number of shares of Common Stock into which this Debenture might
have been converted immediately before such merger, consolidation, sale or
transfer, subject to adjustments which shall be as nearly equivalent as may be
practicable to adjustments provided for in this Article 3.

     Section 3.8 Company Optional Redemption. In the event the closing bid price
on the day prior to the Conversion Date is less than the closing bid price on
the Closing Date, the Company, at its sole option, shall have the right to
exercise an "Optional Redemption" to redeem the amount being converted, as
follows: The Company must notify the Holder in writing that it is exercising its
right of Optional Redemption on the same day the Company receives a notice of
conversion from the Holder, as long as such notice of conversion is received by
the Company before 11:00 a.m. New York time, otherwise the Company has until the
next business day to exercise such right. In the event the Company exercises
such right of Optional Redemption up to and including the 90th calendar day
following the Closing Date, the Company shall pay the Holder in U.S. currency
127% of the face amount of the Debenture being redeemed (133% if after 90
calendar days), plus accrued interest, however, any liquidated damages resulting
from failure to file the registration statement within 30 calendar days of the
Closing Date or failure of the registration statement to be declared effective
within 120 calendar days of the Closing Date shall be waived by the Holder if
the Company exercises its rights of Optional Redemption on or before the 120th
calendar day following the Closing Date, as long as the redemption amount is
paid to the Holder within 5 calendar days of the date the Holder receives
written notice from the Company of the Optional Redemption notice.

Article 4.  Mergers

     The Company shall not consolidate or merge into, or transfer all or
substantially all of its assets to, any person, unless such person assumes in
writing the obligations of the Company under this Debenture and immediately
after such transaction no Event of Default exists. Any reference herein to the
Company shall refer to such surviving or transferee corporation and the
obligations of the Company shall terminate upon such written assumption.

Article 5.  Reports

     The Company will mail to the Holder hereof at its address as shown on the
Register a copy of any annual, quarterly or current report that it files with
the Securities and Exchange Commission promptly after the filing thereof and a
copy of any annual, quarterly or other report or proxy statement that it gives
to its shareholders generally at the time such report or statement is sent to
shareholders.

Article 6.  Defaults and Remedies

     Section 6.1.  Events of Default.  An "Event of Default" occurs if (a) the
Company does not make the payment of the principal of this Debenture by
conversion into Common Stock within ten (10) business days of the Maturity Date,
upon redemption or otherwise, (b) the Company does not make a payment, other
than a payment of principal, for a period of five (5) business days thereafter,
(c) any of the Company's representations or warranties contained in the
Subscription Agreement or this Debenture were false when made or the Company
fails to comply with any of its other agreements in the Subscription Agreement
or this Debenture and such failure continues for the period and after the notice
specified below, (d) the Company pursuant to or within the meaning of any
Bankruptcy Law (as hereinafter defined): (i) commences a voluntary case; (ii)
consents to the entry of an order for relief against it in an involuntary case;
(iii) consents to the appointment of a Custodian (as hereinafter defined) of it
or for all or substantially all of its property or (iv) makes a general
assignment for the benefit of its creditors or (v) a court of competent
jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for
relief against the Company in an involuntary case; (B) appoints a Custodian of
the Company or for all or substantially all of its property or (C) orders the
liquidation of the Company, and the order or decree remains unstayed and in
effect for sixty (60) calendar days, (e) the Company's Common Stock is suspended
or no longer listed on any recognized exchange including electronic
over-the-counter bulletin board for in excess of five (5) consecutive trading
days. As used in this Section 6.1, the term "Bankruptcy Law" means Title 11 of
the United States Code or any similar federal or state law for the relief of
debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator
or similar official under any Bankruptcy Law. A default under clause (c) above
is not an Event of Default until the holders of at least 25% of the aggregate
principal amount of the Debentures outstanding notify the Company of such
default and the Company does not cure it within thirty (30) business days after
the receipt of such notice, unless the Company commences to cure such default
within such period, which must specify the default, demand that it be remedied
and state that it is a "Notice of Default".

     Section 6.2. Acceleration. If an Event of Default occurs and is continuing,
the Holder hereof by notice to the Company, may declare the remaining principal
amount of this Debenture, together with all accrued interest and any liquidated
damages, to be due and payable. Upon such declaration, the remaining principal
amount shall be due and payable immediately.

     Section 6.3 Concerning Seniority.  Except as disclosed in the Company's SEC
filings, no indebtedness of the Company is senior to this Debenture in right of
payment, whether with respect to interest, damages or upon liquidation or
dissolution or otherwise.

     Section 6.4  Liquidation Value.  The liquidation value of this Debenture
shall be equal to 125% of the outstanding balance remaining on this Debenture
plus accrued but unpaid interest and liquidated damages.

Article 7.  Registered Debentures

     Section  7.1.  Series. This Debenture is one of a numbered series of
Debentures which are identical except as to the principal amount and date of
issuance thereof. Such Debentures are referred to herein collectively as the
"Debentures". The Debentures shall be issued in whole multiples of $5,000.

     Section 7.2. Record Ownership. The Company, or its attorney, shall maintain
a register of the holders of the Debentures (the "Register") showing their names
and addresses and the serial numbers and principal amounts of Debentures issued
to them. The Register may be maintained in electronic, magnetic or other
computerized form. The Company may treat the person named as the Holder of this
Debenture in the Register as the sole owner of this Debenture. The Holder of
this Debenture is the person exclusively entitled to receive payments of
interest on this Debenture, receive notifications with respect to this
Debenture, convert it into Common Stock and otherwise exercise all of the rights
and powers as the absolute owner hereof.

     Section 7.3.  Worn or Lost  Debentures. If this Debenture becomes worn,
defaced or mutilated but is still substantially intact and recognizable, the
Company or its agent may issue a new Debenture in lieu hereof upon its
surrender. Where the Holder of this Debenture claims that the Debenture has been
lost, destroyed or wrongfully taken, the Company shall issue a new Debenture in
place of the original Debenture if the Holder so requests by written notice to
the Company actually received by the Company before it is notified that the
Debenture has been acquired by a bona fide purchaser and the Holder has
delivered to the Company an indemnity bond in such amount and issued by such
surety as the Company deems satisfactory together with an affidavit of the
Holder setting forth the facts concerning such loss, destruction or wrongful
taking and such other information in such form with such proof or verification
as the Company may request.

Article 8.  Notice.

     Any notices, consents, waivers or other communications required or
permitted to be given under the terms of this Debenture must be in writing and
will be deemed to have been delivered (i) upon receipt, when delivered
personally; (ii) upon receipt, when sent by facsimile (provided a confirmation
of transmission is mechanically or electronically generated and kept on file by
the sending party); or (iii) one (1) day after deposit with a nationally
recognized overnight delivery service, in each case properly addressed to the

     In this  Debenture, unless the context otherwise requires, words in the
singular number include the plural, and in the plural include the singular, and
words of the masculine gender include the feminine and the neuter, and when the
sense so indicates, words of the neuter gender may refer to any gender. The
numbers and titles of sections contained in the Debenture are inserted for
convenience of reference only, and they neither form a part of this Debenture
nor are they to be used in the construction or interpretation hereof. Wherever,
in this Debenture, a determination of the Company is required or allowed, such

Company and if it is made in good faith, it shall be conclusive and binding upon
the Company and the Holder of this Debenture.

Article 12.  Governing Law

     The validity, terms, performance and enforcement of this Debenture shall be
governed and construed by the provisions hereof and in accordance with the laws
of the State of Florida applicable to agreements that are negotiated, executed,
delivered and performed solely in the State of Florida.

Article 13.       Litigation

     (a) Forum Selection and Consent to Jurisdiction. Any litigation arising out
of, under, or in connection with, this Debenture or any course of conduct,
course of dealing, statements (whether oral or written) or actions of the
Company or Holder shall be brought and maintained exclusively in the courts of

the jurisdiction of the state and federal courts of the State of Florida for the
purpose of any such litigation as set forth above and irrevocably agrees to be
bound by any final judgment rendered thereby in connection with such litigation.
The Company further irrevocably consents to the service of process by registered
mail, postage prepaid, or by personal service within or without the State of
Florida. The Company hereby expressly and irrevocably waives, to the fullest
extent permitted by law, any objection which it may have or hereafter may have
to the laying of venue of any such litigation brought in any such court referred
to above and any claim that any such litigation has been brought in any
inconvenient forum. To the extent that the Company has or hereafter may acquire
any immunity from jurisdiction of any court or from any legal process (whether
through service or notice, attachment prior to judgment, attachment in aid of
execution or otherwise) with respect to itself or its property, the Company
hereby irrevocably waives such immunity in respect of its obligations under this
Debenture.

     (b) Waiver of Jury Trial.  The Holder and the Company hereby knowingly,
