                        CALLABLE SECURED CONVERTIBLE NOTE

South Plainfield, New Jersey
May 28, 2004                                                            $303,375

            FOR VALUE RECEIVED, VERTEX INTERACTIVE, INC., a New Jersey
corporation (hereinafter called the "BORROWER"), hereby promises to pay to the
order of AJW Qualified Partners, LLC or registered assigns (the "HOLDER") the
sum of $303,375, on May 28, 2006 (the "MATURITY DATE"), and to pay interest on
the unpaid principal balance hereof at the rate of ten percent (10%) per annum
from May 28, 2004 (the "ISSUE DATE") until the same becomes due and payable,
whether at maturity or upon acceleration or by prepayment or otherwise. Any
amount of principal or interest on this Note which is not paid when due shall
bear interest at the rate of fifteen percent (15%) per annum from the due date
thereof until the same is paid ("DEFAULT INTEREST"). Interest shall commence
accruing on the issue date, shall be computed on the basis of a 365-day year and
the actual number of days elapsed and shall be payable, quarterly on March 31,
June 30, September 30 and December 31 of each year beginning on June 30, 2004.
All payments due hereunder (to the extent not converted into common stock, $.005
par value per share, of the Borrower (the "COMMON STOCK") in accordance with the
terms hereof) shall be made in lawful money of the United States of America,
provided that: (i) the interest payments due for the first six months following
the Issue Date shall be payable on the date hereof and (ii) the remaining
interest payments due and payable through the Maturity Date shall be placed into
escrow on the date hereof and shall be distributed as set forth in that certain
Escrow Agreement of even date herewith. All payments shall be made at such
address as the Holder shall hereafter give to the Borrower by written notice
made in accordance with the provisions of this Note. Whenever any amount
expressed to be due by the terms of this Note is due on any day which is not a
business day, the same shall instead be due on the next succeeding day which is
a business day and, in the case of any interest payment date which is not the
date on which this Note is paid in full, the extension of the due date thereof
shall not be taken into account for purposes of determining the amount of
interest due on such date. As used in this Note, the term "business day" shall
mean any day other than a Saturday, Sunday or a day on which commercial banks in
the city of New York, New York are authorized or required by law or executive
order to remain closed. Each capitalized term used herein, and not otherwise
defined, shall have the meaning ascribed thereto in that certain Securities
Purchase Agreement, dated April 28, 2004, pursuant to which this Note was
originally issued (the "PURCHASE AGREEMENT").

<PAGE>

      This Note is free from all taxes, liens, claims and encumbrances with
respect to the issue thereof and shall not be subject to preemptive rights or
other similar rights of shareholders of the Borrower and will not impose
personal liability upon the holder thereof. The obligations of the Borrower
under this Note shall be secured by that certain Security Agreement, dated April
28, 2004, by and between the Borrower and the Holder.

      The following terms shall apply to this Note:

                          ARTICLE I. CONVERSION RIGHTS

            1.1 CONVERSION RIGHT. The Holder shall have the right from time to
time, and at any time on or prior to the earlier of (i) the Maturity Date and
(ii) the date of payment of the Default Amount (as defined in Article III)
pursuant to Section 1.6(a) or Article III, the Optional Prepayment Amount (as
defined in Section 5.1 or any payments pursuant to Section 1.7, each in respect
of the remaining outstanding principal amount of this Note to convert all or any
part of the outstanding and unpaid principal amount of this Note into fully paid
and non-assessable shares of Common Stock, as such Common Stock exists on the
Issue Date, or any shares of capital stock or other securities of the Borrower
into which such Common Stock shall hereafter be changed or reclassified at the
conversion price (the "CONVERSION PRICE") determined as provided herein (a
"CONVERSION"); PROVIDED, HOWEVER, that in no event shall the Holder be entitled
to convert any portion of this Note in excess of that portion of this Note upon
conversion of which the sum of (1) the number of shares of Common Stock
beneficially owned by the Holder and its affiliates (other than shares of Common
Stock which may be deemed beneficially owned through the ownership of the
unconverted portion of the Notes or the unexercised or unconverted portion of
any other security of the Borrower (including, without limitation, the warrants
issued by the Borrower pursuant to the Purchase Agreement) subject to a
limitation on conversion or exercise analogous to the limitations contained
herein) and (2) the number of shares of Common Stock issuable upon the
conversion of the portion of this Note with respect to which the determination
of this proviso is being made, would result in beneficial ownership by the
Holder and its affiliates of more than 4.9% of the outstanding shares of Common
Stock. For purposes of the proviso to the immediately preceding sentence,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder,
except as otherwise provided in clause (1) of such proviso. The number of shares
of Common Stock to be issued upon each conversion of this Note shall be
determined by dividing the Conversion Amount (as defined below) by the
applicable Conversion Price then in effect on the date specified in the notice
of conversion, in the form attached hereto as Exhibit A (the "NOTICE OF
CONVERSION"), delivered to the Borrower by the Holder in accordance with Section
1.4 below; provided that the Notice of Conversion is submitted by facsimile (or
by other means resulting in, or reasonably expected to result in, notice) to the
Borrower before 6:00 p.m., New York, New York time on such conversion date (the
"CONVERSION DATE"). The term "CONVERSION AMOUNT" means, with respect to any
conversion of this Note, the sum of (1) the principal amount of this Note to be
converted in such conversion PLUS (2) accrued and unpaid interest, if any, on
such principal amount at the interest rates provided in this Note to the
Conversion Date PLUS (3) Default Interest, if any, on the amounts referred to in
the immediately preceding clauses (1) and/or (2) PLUS (4) at the Holder's
option, any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g)
hereof or pursuant to Section 2(c) of that certain Registration Rights
Agreement, dated as of April 28, 2004, executed in connection with the initial
issuance of this Note and the other Notes issued on the Issue Date (the
"REGISTRATION RIGHTS AGREEMENT").

            1.2 CONVERSION PRICE.

                  (A) CALCULATION OF CONVERSION PRICE. The Conversion Price
shall be the lesser of (i) the Variable Conversion Price (as defined herein) and
(ii) the Fixed Conversion Price (as defined herein) (subject, in each case, to
equitable adjustments for stock splits, stock dividends or rights offerings by
the Borrower relating to the Borrower's securities or the securities of any
subsidiary of the Borrower, combinations, recapitalization, reclassifications,
extraordinary distributions and similar events). The "VARIABLE CONVERSION PRICE"
shall mean the Applicable Percentage (as defined herein) multiplied by the
Market Price (as defined herein). "MARKET PRICE" means the average of the lowest
three (3) Trading Prices (as defined below) for the Common Stock during the
twenty (20) Trading Day period ending one Trading Day prior to the date the
Conversion Notice is sent by the Holder to the Borrower via facsimile (the
"CONVERSION DATE"). "TRADING PRICE" means, for any security as of any date, the
intraday trading price on the Over-the-Counter Bulletin Board (the "OTCBB") as
reported by a reliable reporting service mutually acceptable to and hereafter
designated by Holders of a majority in interest of the Notes and the Borrower
or, if the OTCBB is not the principal trading market for such security, the
intraday trading price of such security on the principal securities exchange or
trading market where such security is listed or traded or, if no intraday
trading price of such security is available in any of the foregoing manners, the
average of the intraday trading prices of any market makers for such security
that are listed in the "pink sheets" by the National Quotation Bureau, Inc. If
the Trading Price cannot be calculated for such security on such date in the
manner provided above, the Trading Price shall be the fair market value as
mutually determined by the Borrower and the holders of a majority in interest of
the Notes being converted for which the calculation of the Trading Price is
required in order to determine the Conversion Price of such Notes. "TRADING DAY"
shall mean any day on which the Common Stock is traded for any period on the
OTCBB, or on the principal securities exchange or other securities market on
which the Common Stock is then being traded. "APPLICABLE PERCENTAGE" shall mean
55.0%. The "FIXED CONVERSION PRICE" shall mean $.30.

                  (B) CONVERSION PRICE DURING MAJOR ANNOUNCEMENTS.
Notwithstanding anything contained in Section 1.2(a) to the contrary, in the
event the Borrower (i) makes a public announcement that it intends to
consolidate or merge with any other corporation (other than a merger in which
the Borrower is the surviving or continuing corporation and its capital stock is
unchanged) or sell or transfer all or substantially all of the assets of the
Borrower or (ii) any person, group or entity (including the Borrower) publicly
announces a tender offer to purchase 50% or more of the Borrower's Common Stock
(or any other takeover scheme) (the date of the announcement referred to in
clause (i) or (ii) is hereinafter referred to as the "ANNOUNCEMENT DATE"), then
the Conversion Price shall, effective upon the Announcement Date and continuing
through the Adjusted Conversion Price Termination Date (as defined below), be
equal to the lower of (x) the Conversion Price which would have been applicable
for a Conversion occurring on the Announcement Date and (y) the Conversion Price
that would otherwise be in effect. From and after the Adjusted Conversion Price
Termination Date, the Conversion Price shall be determined as set forth in this
Section 1.2(a). For purposes hereof, "ADJUSTED CONVERSION PRICE TERMINATION
DATE" shall mean, with respect to any proposed transaction or tender offer (or
takeover scheme) for which a public announcement as contemplated by this Section
1.2(b) has been made, the date upon which the Borrower (in the case of clause
(i) above) or the person, group or entity (in the case of clause (ii) above)
consummates or publicly announces the termination or abandonment of the proposed
transaction or tender offer (or takeover scheme) which caused this Section
1.2(b) to become operative.


                                       3

            1.3 AUTHORIZED SHARES. Subject to the Stockholder Approval (as
defined in the Agreement), the Borrower covenants that during the period the
conversion right exists, the Borrower will reserve from its authorized and
unissued Common Stock a sufficient number of shares, free from preemptive
rights, to provide for the issuance of Common Stock upon the full conversion of
this Note and the other Notes issued pursuant to the Purchase Agreement. The
Borrower is required at all times to have authorized and reserved two times the
number of shares that is actually issuable upon full conversion of the Notes
(based on the Conversion Price of the Notes or the Exercise Price of the
Warrants in effect from time to time) (the "RESERVED AMOUNT"). The Reserved
Amount shall be increased from time to time in accordance with the Borrower's
obligations pursuant to Section 4(h) of the Purchase Agreement. The Borrower
represents that upon issuance, such shares will be duly and validly issued,
fully paid and non-assessable. In addition, if the Borrower shall issue any
securities or make any change to its capital structure which would change the
number of shares of Common Stock into which the Notes shall be convertible at
the then current Conversion Price, the Borrower shall at the same time make
proper provision so that thereafter there shall be a sufficient number of shares
of Common Stock authorized and reserved, free from preemptive rights, for
conversion of the outstanding Notes. The Borrower (i) acknowledges that it has
irrevocably instructed its transfer agent to issue certificates for the Common
Stock issuable upon conversion of this Note, and (ii) agrees that its issuance
of this Note shall constitute full authority to its officers and agents who are
charged with the duty of executing stock certificates to execute and issue the
necessary certificates for shares of Common Stock in accordance with the terms
and conditions of this Note.

            If, at any time a Holder of this Note submits a Notice of
Conversion, and the Borrower does not have sufficient authorized but unissued
shares of Common Stock available to effect such conversion in accordance with
the provisions of this Article I (a "CONVERSION DEFAULT"), subject to Section
4.8, the Borrower shall issue to the Holder all of the shares of Common Stock
which are then available to effect such conversion. The portion of this Note
which the Holder included in its Conversion Notice and which exceeds the amount
which is then convertible into available shares of Common Stock (the "EXCESS
AMOUNT") shall, notwithstanding anything to the contrary contained herein, not
be convertible into Common Stock in accordance with the terms hereof until (and
at the Holder's option at any time after) the date additional shares of Common
Stock are authorized by the Borrower to permit such conversion, at which time
the Conversion Price in respect thereof shall be the lesser of (i) the
Conversion Price on the Conversion Default Date (as defined below) and (ii) the
Conversion Price on the Conversion Date thereafter elected by the Holder in
respect thereof. In addition, the Borrower shall pay to the Holder payments
("CONVERSION DEFAULT PAYMENTS") for a Conversion Default in the amount of (x)
the SUM OF (1) the then outstanding principal amount of this Note PLUS (2)
accrued and unpaid interest on the unpaid principal amount of this Note through
the Authorization Date (as defined below) PLUS (3) Default Interest, if any, on
the amounts referred to in clauses (1) and/or (2), MULTIPLIED BY (y) .24,
MULTIPLIED BY (z) (N/365), where N = the number of days from the day the holder
submits a Notice of Conversion giving rise to a Conversion Default (the
"CONVERSION DEFAULT DATE") to the date (the "AUTHORIZATION DATE") that the
Borrower authorizes a sufficient number of shares of Common Stock to effect
conversion of the full outstanding principal balance of this Note. The Borrower
shall use its best efforts to authorize a sufficient number of shares of Common
Stock as soon as practicable following the earlier of (i) such time that the
Holder notifies the Borrower or that the Borrower otherwise becomes aware that
there are or likely will be insufficient authorized and unissued shares to allow
full conversion thereof and (ii) a Conversion Default. The Borrower shall send
notice to the Holder of the authorization of additional shares of Common Stock,
the Authorization Date and the amount of Holder's accrued Conversion Default
Payments. The accrued Conversion Default Payments for each calendar month shall
be paid in cash or shall be convertible into Common Stock (at such time as there
are sufficient authorized shares of Common Stock) at the applicable Conversion
Price, at the Borrower's option, as follows:


                                       4
<PAGE>

                  (A) In the event Holder elects to take such payment in cash,
cash payment shall be made to Holder by the fifth (5th) day of the month
following the month in which it has accrued; and

                  (B) In the event Holder elects to take such payment in Common
Stock, the Holder may convert such payment amount into Common Stock at the
Conversion Price (as in effect at the time of conversion) at any time after the
fifth day of the month following the month in which it has accrued in accordance
with the terms of this Article I (so long as there is then a sufficient number
of authorized shares of Common Stock).

            The Holder's election shall be made in writing to the Borrower at
any time prior to 6:00 p.m., New York, New York time, on the third day of the
month following the month in which Conversion Default payments have accrued. If
no election is made, the Holder shall be deemed to have elected to receive cash.
Nothing herein shall limit the Holder's right to pursue actual damages (to the
extent in excess of the Conversion Default Payments) for the Borrower's failure
to maintain a sufficient number of authorized shares of Common Stock, and each
holder shall have the right to pursue all remedies available at law or in equity
(including degree of specific performance and/or injunctive relief).

            1.4 METHOD OF CONVERSION.

                  (A) MECHANICS OF CONVERSION. Subject to Section 1.1, this Note
may be converted by the Holder in whole or in part at any time from time to time
after the Issue Date, by (A) submitting to the Borrower a Notice of Conversion
(by facsimile or other reasonable means of communication dispatched on the
Conversion Date prior to 6:00 p.m., New York, New York time) and (B) subject to
Section 1.4(b), surrendering this Note at the principal office of the Borrower.


                                       5
<PAGE>


                  (B) SURRENDER OF NOTE UPON CONVERSION. Notwithstanding
anything to the contrary set forth herein, upon conversion of this Note in
accordance with the terms hereof, the Holder shall not be required to physically
surrender this Note to the Borrower unless the entire unpaid principal amount of
this Note is so converted. The Holder and the Borrower shall maintain records
showing the principal amount so converted and the dates of such conversions or
shall use such other method, reasonably satisfactory to the Holder and the
Borrower, so as not to require physical surrender of this Note upon each such
conversion. In the event of any dispute or discrepancy, such records of the
Borrower shall be controlling and determinative in the absence of manifest
error. Notwithstanding the foregoing, if any portion of this Note is converted
as aforesaid, the Holder may not transfer this Note unless the Holder first
physically surrenders this Note to the Borrower, whereupon the Borrower will
forthwith issue and deliver upon the order of the Holder a new Note of like
tenor, registered as the Holder (upon payment by the Holder of any applicable
transfer taxes) may request, representing in the aggregate the remaining unpaid
principal amount of this Note. The Holder and any assignee, by acceptance of
this Note, acknowledge and agree that, by reason of the provisions of this
paragraph, following conversion of a portion of this Note, the unpaid and
unconverted principal amount of this Note represented by this Note may be less
than the amount stated on the face hereof.

                  (C) PAYMENT OF TAXES. The Borrower shall not be required to
pay any tax which may be payable in respect of any transfer involved in the
issue and delivery of shares of Common Stock or other securities or property on
conversion of this Note in a name other than that of the Holder (or in street
name), and the Borrower shall not be required to issue or deliver any such
shares or other securities or property unless and until the person or persons
(other than the Holder or the custodian in whose street name such shares are to
be held for the Holder's account) requesting the issuance thereof shall have
paid to the Borrower the amount of any such tax or shall have established to the
satisfaction of the Borrower that such tax has been paid.

                  (D) DELIVERY OF COMMON STOCK UPON CONVERSION. Upon receipt by
the Borrower from the Holder of a facsimile transmission (or other reasonable
means of communication) of a Notice of Conversion meeting the requirements for
conversion as provided in this Section 1.4, the Borrower shall issue and deliver
or cause to be issued and delivered to or upon the order of the Holder
certificates for the Common Stock issuable upon such conversion within two (2)
business days after such receipt (and, solely in the case of conversion of the
entire unpaid principal amount hereof, surrender of this Note) (such second
business day being hereinafter referred to as the "DEADLINE") in accordance with
the terms hereof and the Purchase Agreement (including, without limitation, in
accordance with the requirements of Section 2(g) of the Purchase Agreement that
certificates for shares of Common Stock issued on or after the effective date of
the Registration Statement upon conversion of this Note shall not bear any
restrictive legend).


                                       6
<PAGE>


                  (E) OBLIGATION OF BORROWER TO DELIVER COMMON STOCK. Upon
receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed to
be the holder of record of the Common Stock issuable upon such conversion, the
outstanding principal amount and the amount of accrued and unpaid interest on
this Note shall be reduced to reflect such conversion, and, unless the Borrower
defaults on its obligations under this Article I, all rights with respect to the
portion of this Note being so converted shall forthwith terminate except the
right to receive the Common Stock or other securities, cash or other assets, as
herein provided, on such conversion. If the Holder shall have given a Notice of
Conversion as provided herein, the Borrower's obligation to issue and deliver
the certificates for Common Stock shall be absolute and unconditional,
irrespective of the absence of any action by the Holder to enforce the same, any
waiver or consent with respect to any provision thereof, the recovery of any
judgment against any person or any action to enforce the same, any failure or
delay in the enforcement of any other obligation of the Borrower to the holder
of record, or any setoff, counterclaim, recoupment, limitation or termination,
or any breach or alleged breach by the Holder of any obligation to the Borrower,
and irrespective of any other circumstance which might otherwise limit such
obligation of the Borrower to the Holder in connection with such conversion. The
Conversion Date specified in the Notice of Conversion shall be the Conversion
Date so long as the Notice of Conversion is received by the Borrower before 6:00
p.m., New York, New York time, on such date.

                  (F) DELIVERY OF COMMON STOCK BY ELECTRONIC TRANSFER. In lieu
of delivering physical certificates representing the Common Stock issuable upon
conversion, provided the Borrower's transfer agent is participating in the
Depository Trust Company ("DTC") Fast Automated Securities Transfer ("FAST")
program, upon request of the Holder and its compliance with the provisions
contained in Section 1.1 and in this Section 1.4, the Borrower shall use its
best efforts to cause its transfer agent to electronically transmit the Common
Stock issuable upon conversion to the Holder by crediting the account of
Holder's Prime Broker with DTC through its Deposit Withdrawal Agent Commission
("DWAC") system.

                  (G) FAILURE TO DELIVER COMMON STOCK PRIOR TO DEADLINE. Without
in any way limiting the Holder's right to pursue other remedies, including
actual damages and/or equitable relief, the parties agree that if delivery of
the Common Stock issuable upon conversion of this Note is more than two (2) days
after the Deadline (other than a failure due to the circumstances described in
Section 1.3 above, which failure shall be governed by such Section) the Borrower
shall pay to the Holder $2,000 per day in cash, for each day beyond the Deadline
that the Borrower fails to deliver such Common Stock. Such cash amount shall be
paid to Holder by the fifth day of the month following the month in which it has
accrued or, at the option of the Holder (by written notice to the Borrower by
the first day of the month following the month in which it has accrued), shall
be added to the principal amount of this Note, in which event interest shall
accrue thereon in accordance with the terms of this Note and such additional
principal amount shall be convertible into Common Stock in accordance with the
terms of this Note.

            1.5 CONCERNING THE SHARES. The shares of Common Stock issuable upon
conversion of this Note may not be sold or transferred unless (i) such shares
are sold pursuant to an effective registration statement under the Act or (ii)
the Borrower or its transfer agent shall have been furnished with an opinion of
counsel (which opinion shall be in form, substance and scope customary for
opinions of counsel in comparable transactions) to the effect that the shares to
be sold or transferred may be sold or transferred pursuant to an exemption from
such registration or (iii) such shares are sold or transferred pursuant to Rule
144 under the Act (or a successor rule) ("RULE 144") or (iv) such shares are
transferred to an "affiliate" (as defined in Rule 144) of the Borrower who
agrees to sell or otherwise transfer the shares only in accordance with this
Section 1.5 and who is an Accredited Investor (as defined in the Purchase
Agreement). Except as otherwise provided in the Purchase Agreement (and subject
to the removal provisions set forth below), until such time as the shares of
Common Stock issuable upon conversion of this Note have been registered under
the Act as contemplated by the Registration Rights Agreement or otherwise may be
sold pursuant to Rule 144 without any restriction as to the number of securities
as of a particular date that can then be immediately sold, each certificate for
shares of Common Stock issuable upon conversion of this Note that has not been
so included in an effective registration statement or that has not been sold
pursuant to an effective registration statement or an exemption that permits
removal of the legend, shall bear a legend substantially in the following form,
as appropriate:


                                       7
<PAGE>


            "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE
            SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE
            OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID
            ACT, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND SCOPE CUSTOMARY
            FOR OPINIONS OF COUNSEL IN COMPARABLE TRANSACTIONS, THAT
            REGISTRATION IS NOT REQUIRED UNDER SAID ACT UNLESS SOLD PURSUANT TO
            RULE 144 OR REGULATION S UNDER SAID ACT."

            The legend set forth above shall be removed and the Borrower shall
issue to the Holder a new certificate therefor free of any transfer legend if
(i) the Borrower or its transfer agent shall have received an opinion of
counsel, in form, substance and scope customary for opinions of counsel in
comparable transactions, to the effect that a public sale or transfer of such
Common Stock may be made without registration under the Act and the shares are
so sold or transferred, (ii) such Holder provides the Borrower or its transfer
agent with reasonable assurances that the Common Stock issuable upon conversion
of this Note (to the extent such securities are deemed to have been acquired on
the same date) can be sold pursuant to Rule 144 or (iii) in the case of the
Common Stock issuable upon conversion of this Note, such security is registered
for sale by the Holder under an effective registration statement filed under the
Act or otherwise may be sold pursuant to Rule 144 without any restriction as to
the number of securities as of a particular date that can then be immediately
sold. Nothing in this Note shall (i) limit the Borrower's obligation under the
Registration Rights Agreement or (ii) affect in any way the Holder's obligations
to comply with applicable prospectus delivery requirements upon the resale of
the securities referred to herein.

            1.6 EFFECT OF CERTAIN EVENTS.

                  (A) EFFECT OF MERGER, CONSOLIDATION, ETC. At the option of the
Holder, the sale, conveyance or disposition of all or substantially all of the
assets of the Borrower, the effectuation by the Borrower of a transaction or
series of related transactions in which more than 50% of the voting power of the
Borrower is disposed of, or the consolidation, merger or other business
combination of the Borrower with or into any other Person (as defined below) or
Persons when the Borrower is not the survivor shall either: (i) be deemed to be
an Event of Default (as defined in Article III) pursuant to which the Borrower
shall be required to pay to the Holder upon the consummation of and as a
condition to such transaction an amount equal to the Default Amount (as defined
in Article III) or (ii) be treated pursuant to Section 1.6(b) hereof. "PERSON"
shall mean any individual, corporation, limited liability company, partnership,
association, trust or other entity or organization.

<PAGE>


                  (B) ADJUSTMENT DUE TO MERGER, CONSOLIDATION, ETC. If, at any
time when this Note is issued and outstanding and prior to conversion of all of
the Notes, there shall be any merger, consolidation, exchange of shares,
recapitalization, reorganization, or other similar event, as a result of which
shares of Common Stock of the Borrower shall be changed into the same or a
different number of shares of another class or classes of stock or securities of
the Borrower or another entity, or in case of any sale or conveyance of all or
substantially all of the assets of the Borrower other than in connection with a
plan of complete liquidation of the Borrower, then the Holder of this Note shall
thereafter have the right to receive upon conversion of this Note, upon the
basis and upon the terms and conditions specified herein and in lieu of the
shares of Common Stock immediately theretofore issuable upon conversion, such
stock, securities or assets which the Holder would have been entitled to receive
in such transaction had this Note been converted in full immediately prior to
such transaction (without regard to any limitations on conversion set forth
herein), and in any such case appropriate provisions shall be made with respect
to the rights and interests of the Holder of this Note to the end that the
provisions hereof (including, without limitation, provisions for adjustment of
the Conversion Price and of the number of shares issuable upon conversion of the
Note) shall thereafter be applicable, as nearly as may be practicable in
relation to any securities or assets thereafter deliverable upon the conversion
hereof. The Borrower shall not effect any transaction described in this Section
1.6(b) unless (a) it first gives, to the extent practicable, thirty (30) days
prior written notice (but in any event at least fifteen (15) days prior written
notice) of the record date of the special meeting of shareholders to approve, or
if there is no such record date, the consummation of, such merger,
consolidation, exchange of shares, recapitalization, reorganization or other
similar event or sale of assets (during which time the Holder shall be entitled
to convert this Note) and (b) the resulting successor or acquiring entity (if
not the Borrower) assumes by written instrument the obligations of this Section
1.6(b). The above provisions shall similarly apply to successive consolidations,
mergers, sales, transfers or share exchanges.

                  (C) ADJUSTMENT DUE TO DISTRIBUTION. If the Borrower shall
declare or make any distribution of its assets (or rights to acquire its assets)
to holders of Common Stock as a dividend, stock repurchase, by way of return of
capital or otherwise (including any dividend or distribution to the Borrower's
shareholders in cash or shares (or rights to acquire shares) of capital stock of
a subsidiary (i.e., a spin-off)) (a "DISTRIBUTION"), then the Holder of this
Note shall be entitled, upon any conversion of this Note after the date of
record for determining shareholders entitled to such Distribution, to receive
the amount of such assets which would have been payable to the Holder with
respect to the shares of Common Stock issuable upon such conversion had such
Holder been the holder of such shares of Common Stock on the record date for the
determination of shareholders entitled to such Distribution.

                  (D) ADJUSTMENT DUE TO DILUTIVE ISSUANCE. If, at any time when
any Notes are issued and outstanding, the Borrower issues or sells, or in
accordance with this Section 1.6(d) hereof is deemed to have issued or sold, any
shares of Common Stock for no consideration or for a consideration per share
(before deduction of reasonable expenses or commissions or underwriting
discounts or allowances in connection therewith) less than the Fixed Conversion
Price in effect on the date of such issuance (or deemed issuance) of such shares
of Common Stock (a "DILUTIVE ISSUANCE"), then immediately upon the Dilutive
Issuance, the Fixed Conversion Price will be reduced to the amount of the
consideration per share received by the Borrower in such Dilutive Issuance;
PROVIDED that only one adjustment will be made for each Dilutive Issuance.

                  The Borrower shall be deemed to have issued or sold shares of
Common Stock if the Borrower in any manner issues or grants any warrants, rights
or options (not including employee stock option plans), whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities convertible into or exchangeable for Common Stock ("CONVERTIBLE
SECURITIES") (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred to as "OPTIONS") and the price
per share for which Common Stock is issuable upon the exercise of such Options
is less than the Fixed Conversion Price then in effect, then the Fixed
Conversion Price shall be equal to such price per share. For purposes of the
preceding sentence, the "price per share for which Common Stock is issuable upon
the exercise of such Options" is determined by dividing (i) the total amount, if
any, received or receivable by the Borrower as consideration for the issuance or
granting of all such Options, plus the minimum aggregate amount of additional
consideration, if any, payable to the Borrower upon the exercise of all such
Options, plus, in the case of Convertible Securities issuable upon the exercise
of such Options, the minimum aggregate amount of additional consideration
payable upon the conversion or exchange thereof at the time such Convertible
Securities first become convertible or exchangeable, by (ii) the maximum total
number of shares of Common Stock issuable upon the exercise of all such Options
(assuming full conversion of Convertible Securities, if applicable). No further
adjustment to the Conversion Price will be made upon the actual issuance of such
Common Stock upon the exercise of such Options or upon the conversion or
exchange of Convertible Securities issuable upon exercise of such Options.

                  Additionally, the Borrower shall be deemed to have issued or
sold shares of Common Stock if the Borrower in any manner issues or sells any
Convertible Securities, whether or not immediately convertible (other than where
the same are issuable upon the exercise of Options), and the price per share for
which Common Stock is issuable upon such conversion or exchange is less than the
Fixed Conversion Price then in effect, then the Fixed Conversion Price shall be
equal to such price per share. For the purposes of the preceding sentence, the
"price per share for which Common Stock is issuable upon such conversion or
exchange" is determined by dividing (i) the total amount, if any, received or
receivable by the Borrower as consideration for the issuance or sale of all such
Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Borrower upon the conversion or exchange
thereof at the time such Convertible Securities first become convertible or
exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the conversion or exchange of all such Convertible Securities. No
further adjustment to the Fixed Conversion Price will be made upon the actual
issuance of such Common Stock upon conversion or exchange of such Convertible
Securities.

<PAGE>


                  (E) PURCHASE RIGHTS. If, at any time when any Notes are issued
and outstanding, the Borrower issues any convertible securities or rights to
purchase stock, warrants, securities or other property (the "PURCHASE RIGHTS")
pro rata to the record holders of any class of Common Stock, then the Holder of
this Note will be entitled to acquire, upon the terms applicable to such
Purchase Rights, the aggregate Purchase Rights which such Holder could have
acquired if such Holder had held the number of shares of Common Stock acquirable
upon complete conversion of this Note (without regard to any limitations on
conversion contained herein) immediately before the date on which a record is
taken for the grant, issuance or sale of such Purchase Rights or, if no such
record is taken, the date as of which the record holders of Common Stock are to
be determined for the grant, issue or sale of such Purchase Rights.

                  (F) NOTICE OF ADJUSTMENTS. Upon the occurrence of each
adjustment or readjustment of the Conversion Price as a result of the events
described in this Section 1.6, the Borrower, at its expense, shall promptly
compute such adjustment or readjustment and prepare and furnish to the Holder of
a certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based. The
Borrower shall, upon the written request at any time of the Holder, furnish to
such Holder a like certificate setting forth (i) such adjustment or
readjustment, (ii) the Conversion Price at the time in effect and (iii) the
number of shares of Common Stock and the amount, if any, of other securities or
property which at the time would be received upon conversion of the Note.

            1.7 TRADING MARKET LIMITATIONS. Unless permitted by the applicable
rules and regulations of the principal securities market on which the Common
Stock is then listed or traded, in no event shall the Borrower issue upon
conversion of or otherwise pursuant to this Note and the other Notes issued
pursuant to the Purchase Agreement more than the maximum number of shares of
Common Stock that the Borrower can issue pursuant to any rule of the principal
United States securities market on which the Common Stock is then traded (the
"MAXIMUM SHARE AMOUNT"), which shall be 19.99% of the total shares outstanding
on the Closing Date (as defined in the Purchase Agreement), subject to equitable
adjustment from time to time for stock splits, stock dividends, combinations,
capital reorganizations and similar events relating to the Common Stock
occurring after the date hereof. Once the Maximum Share Amount has been issued
(the date of which is hereinafter referred to as the "MAXIMUM CONVERSION DATE"),
if the Borrower fails to eliminate any prohibitions under applicable law or the
rules or regulations of any stock exchange, interdealer quotation system or
other self-regulatory organization with jurisdiction over the Borrower or any of
its securities on the Borrower's ability to issue shares of Common Stock in
excess of the Maximum Share Amount (a "TRADING MARKET PREPAYMENT EVENT"), in
lieu of any further right to convert this Note, and in full satisfaction of the
Borrower's obligations under this Note, the Borrower shall pay to the Holder,
within fifteen (15) business days of the Maximum Conversion Date (the "TRADING
MARKET PREPAYMENT DATE"), an amount equal to 130% TIMES the SUM of (a) the then
outstanding principal amount of this Note immediately following the Maximum
Conversion Date, PLUS (b) accrued and unpaid interest on the unpaid principal
amount of this Note to the Trading Market Prepayment Date, PLUS (c) Default
Interest, if any, on the amounts referred to in clause (a) and/or (b) above,
PLUS (d) any optional amounts that may be added thereto at the Maximum
Conversion Date by the Holder in accordance with the terms hereof (the then
outstanding principal amount of this Note immediately following the Maximum
Conversion Date, PLUS the amounts referred to in clauses (b), (c) and (d) above
shall collectively be referred to as the "REMAINING CONVERTIBLE AMOUNT"). With
respect to each Holder of Notes, the Maximum Share Amount shall refer to such
Holder's PRO RATA share thereof determined in accordance with Section 4.8 below.
In the event that the sum of (x) the aggregate number of shares of Common Stock
issued upon conversion of this Note and the other Notes issued pursuant to the
Purchase Agreement PLUS (y) the aggregate number of shares of Common Stock that
remain issuable upon conversion of this Note and the other Notes issued pursuant
to the Purchase Agreement, represents at least one hundred percent (100%) of the
Maximum Share Amount (the "TRIGGERING EVENT"), the Borrower will use its best
efforts to seek and obtain Shareholder Approval (or obtain such other relief as
will allow conversions hereunder in excess of the Maximum Share Amount) as soon
as practicable following the Triggering Event and before the Maximum Conversion
Date. As used herein, "SHAREHOLDER APPROVAL" means approval by the shareholders
of the Borrower to authorize the issuance of the full number of shares of Common
Stock which would be issuable upon full conversion of the then outstanding Notes
but for the Maximum Share Amount.


                                       11
<PAGE>


            1.8 STATUS AS SHAREHOLDER. Upon submission of a Notice of Conversion
by a Holder, (i) the shares covered thereby (other than the shares, if any,
which cannot be issued because their issuance would exceed such Holder's
allocated portion of the Reserved Amount or Maximum Share Amount) shall be
deemed converted into shares of Common Stock and (ii) the Holder's rights as a
Holder of such converted portion of this Note shall cease and terminate,
excepting only the right to receive certificates for such shares of Common Stock
and to any remedies provided herein or otherwise available at law or in equity
to such Holder because of a failure by the Borrower to comply with the terms of
this Note. Notwithstanding the foregoing, if a Holder has not received
certificates for all shares of Common Stock prior to the tenth (10th) business
day after the expiration of the Deadline with respect to a conversion of any
portion of this Note for any reason, then (unless the Holder otherwise elects to
retain its status as a holder of Common Stock by so notifying the Borrower) the
Holder shall regain the rights of a Holder of this Note with respect to such
unconverted portions of this Note and the Borrower shall, as soon as
practicable, return such unconverted Note to the Holder or, if the Note has not
been surrendered, adjust its records to reflect that such portion of this Note
has not been converted. In all cases, the Holder shall retain all of its rights
and remedies (including, without limitation, (i) the right to receive Conversion
Default Payments pursuant to Section 1.3 to the extent required thereby for such
Conversion Default and any subsequent Conversion Default and (ii) the right to
have the Conversion Price with respect to subsequent conversions determined in
accordance with Section 1.3) for the Borrower's failure to convert this Note.

                         ARTICLE II. CERTAIN COVENANTS

            2.1 DISTRIBUTIONS ON CAPITAL STOCK. So long as the Borrower shall
have any obligation under this Note, the Borrower shall not without the Holder's
written consent (a) pay, declare or set apart for such payment, any dividend or
other distribution (whether in cash, property or other securities) on shares of
capital stock other than dividends on shares of Common Stock solely in the form
of additional shares of Common Stock or (b) directly or indirectly or through
any subsidiary make any other payment or distribution in respect of its capital
stock except for distributions pursuant to any shareholders' rights plan which
is approved by a majority of the Borrower's disinterested directors.


                                       12
<PAGE>


            2.2 RESTRICTION ON STOCK REPURCHASES. So long as the Borrower shall
have any obligation under this Note, the Borrower shall not without the Holder's
written consent redeem, repurchase or otherwise acquire (whether for cash or in
exchange for property or other securities or otherwise) in any one transaction
or series of related transactions any shares of capital stock of the Borrower or
any warrants, rights or options to purchase or acquire any such shares.

            2.3 BORROWINGS. So long as the Borrower shall have any obligation
under this Note, the Borrower shall not, without the Holder's written consent,

except (a) borrowings in existence or committed on the date hereof and of which
the Borrower has informed Holder in writing prior to the date hereof, (b)
indebtedness to trade creditors or financial institutions incurred in the
ordinary course of business or (c) borrowings, the proceeds of which shall be
used to repay this Note.

            2.4 SALE OF ASSETS. So long as the Borrower shall have any
obligation under this Note, the Borrower shall not, without the Holder's written
consent, sell, lease or otherwise dispose of any significant portion of its
assets outside the ordinary course of business. Any consent to the disposition
of any assets may be conditioned on a specified use of the proceeds of
disposition.

            2.5 ADVANCES AND LOANS. So long as the Borrower shall have any
obligation under this Note, the Borrower shall not, without the Holder's written
consent, lend money, give credit or make advances to any person, firm, joint
venture or corporation, including, without limitation, officers, directors,
employees, subsidiaries and affiliates of the Borrower, except loans, credits or
advances (a) in existence or committed on the date hereof and which the Borrower
has informed Holder in writing prior to the date hereof, (b) made in the
ordinary course of business or (c) not in excess of $50,000.

            2.6 CONTINGENT LIABILITIES. So long as the Borrower shall have any
obligation under this Note, the Borrower shall not, without the Holder's written
consent, which shall not be unreasonably withheld, assume, guarantee, endorse,
contingently agree to purchase or otherwise become liable upon the obligation of
any person, firm, partnership, joint venture or corporation, except by the
endorsement of negotiable instruments for deposit or collection and except
assumptions, guarantees, endorsements and contingencies (a) in existence or
committed on the date hereof and which the Borrower has informed Holder in
writing prior to the date hereof, and (b) similar transactions in the ordinary
course of business.

                         ARTICLE III. EVENTS OF DEFAULT

            If any of the following events of default (each, an "EVENT OF
DEFAULT") shall occur:


                                       13
<PAGE>

            3.1 FAILURE TO PAY PRINCIPAL OR INTEREST. The Borrower fails to pay
the principal hereof or interest thereon when due on this Note, whether at
maturity, upon a Trading Market Prepayment Event pursuant to Section 1.7, upon
acceleration or otherwise;

            3.2 CONVERSION AND THE SHARES. The Borrower fails to issue shares of
Common Stock to the Holder (or announces or threatens that it will not honor its
obligation to do so) upon exercise by the Holder of the conversion rights of the
Holder in accordance with the terms of this Note (for a period of at least sixty
(60) days, if such failure is solely as a result of the circumstances governed
by Section 1.3 and the Borrower is using its best efforts to authorize a
sufficient number of shares of Common Stock as soon as practicable), fails to
transfer or cause its transfer agent to transfer (electronically or in
certificated form) any certificate for shares of Common Stock issued to the
Holder upon conversion of or otherwise pursuant to this Note as and when
required by this Note or the Registration Rights Agreement, or fails to remove
any restrictive legend (or to withdraw any stop transfer instructions in respect
thereof) on any certificate for any shares of Common Stock issued to the Holder
upon conversion of or otherwise pursuant to this Note as and when required by
this Note or the Registration Rights Agreement (or makes any announcement,
statement or threat that it does not intend to honor the obligations described
in this paragraph) and any such failure shall continue uncured (or any
announcement, statement or threat not to honor its obligations shall not be
rescinded in writing) for ten (10) days after the Borrower shall have been
notified thereof in writing by the Holder;

            3.3 FAILURE TO TIMELY FILE REGISTRATION OR EFFECT REGISTRATION. The
Borrower fails to file the Registration Statement within sixty (60) days
following the Closing Date (as defined in the Purchase Agreement) or obtain
effectiveness with the Securities and Exchange Commission of the Registration
Statement within one hundred fifteen (115) days following the Closing Date (as
defined in the Purchase Agreement) or such Registration Statement lapses in
effect (or sales cannot otherwise be made thereunder effective, whether by
reason of the Borrower's failure to amend or supplement the prospectus included
therein in accordance with the Registration Rights Agreement or otherwise) for
more than twenty (20) consecutive days or forty (40) days in any twelve month
period after the Registration Statement becomes effective;

            3.4 BREACH OF COVENANTS. The Borrower breaches any material covenant
or other material term or condition contained in Sections 1.3, 1.6 or 1.7 of
this Note, or Sections 4(c), 4(e), 4(h), 4(i), 4(j) or 5 of the Purchase
Agreement and such breach continues for a period of ten (10) days after written
notice thereof to the Borrower from the Holder;

            3.5 BREACH OF REPRESENTATIONS AND WARRANTIES. Any representation or
warranty of the Borrower made herein or in any agreement, statement or
certificate given in writing pursuant hereto or in connection herewith
(including, without limitation, the Purchase Agreement and the Registration
Rights Agreement), shall be false or misleading in any material respect when
made and the breach of which has (or with the passage of time will have) a
material adverse effect on the rights of the Holder with respect to this Note,
the Purchase Agreement or the Registration Rights Agreement;

            3.6 RECEIVER OR TRUSTEE. The Borrower or any subsidiary of the
Borrower shall make an assignment for the benefit of creditors, or apply for or

of its property or other assets for more than $50,000, and shall remain
unvacated, unbonded or unstayed for a period of twenty (20) days unless
otherwise consented to by the Holder, which consent will not be unreasonably
withheld;

            3.8 BANKRUPTCY. Bankruptcy, insolvency, reorganization or

or any law for the relief of debtors shall be instituted by or against the
Borrower or any subsidiary of the Borrower;

            3.9 DELISTING OF COMMON STOCK. The Borrower shall fail to maintain
the listing of the Common Stock on at least one of the OTCBB or an equivalent
replacement exchange, the Nasdaq National Market, the Nasdaq SmallCap Market,
the New York Stock Exchange, or the American Stock Exchange; or

            3.10 DEFAULT UNDER OTHER NOTES. An Event of Default has occurred and
is continuing under any of the other Notes issued pursuant to the Purchase
Agreement,

then, upon the occurrence and during the continuation of any Event of Default
specified in Section 3.1, 3.2, 3.3, 3.4, 3.5, 3.7, 3.9, or 3.10, at the option
of the Holders of a majority of the aggregate principal amount of the
outstanding Notes issued pursuant to the Purchase Agreement exercisable through
the delivery of written notice to the Borrower by such Holders (the "DEFAULT
NOTICE"), and upon the occurrence of an Event of Default specified in Section
3.6 or 3.8, the Notes shall become immediately due and payable and the Borrower
shall pay to the Holder, in full satisfaction of its obligations hereunder, an
amount equal to the greater of (i) 130% TIMES the SUM of (w) the then
outstanding principal amount of this Note PLUS (x) accrued and unpaid interest
on the unpaid principal amount of this Note to the date of payment (the
"MANDATORY PREPAYMENT DATE") PLUS (y) Default Interest, if any, on the amounts
referred to in clauses (w) and/or (x) PLUS (z) any amounts owed to the Holder
pursuant to Sections 1.3 and 1.4(g) hereof or pursuant to Section 2(c) of the
Registration Rights Agreement (the then outstanding principal amount of this
Note to the date of payment PLUS the amounts referred to in clauses (x), (y) and
(z) shall collectively be known as the "DEFAULT SUM") or (ii) the "parity value"
of the Default Sum to be prepaid, where parity value means (a) the highest
number of shares of Common Stock issuable upon conversion of or otherwise
pursuant to such Default Sum in accordance with Article I, treating the Trading
Day immediately preceding the Mandatory Prepayment Date as the "Conversion Date"
for purposes of determining the lowest applicable Conversion Price, unless the
Default Event arises as a result of a breach in respect of a specific Conversion
Date in which case such Conversion Date shall be the Conversion Date),
MULTIPLIED BY (b) the highest Closing Price for the Common Stock during the
period beginning on the date of first occurrence of the Event of Default and
ending one day prior to the Mandatory Prepayment Date (the "DEFAULT AMOUNT") and
all other amounts payable hereunder shall immediately become due and payable,
all without demand, presentment or notice, all of which hereby are expressly
waived, together with all costs, including, without limitation, legal fees and
expenses, of collection, and the Holder shall be entitled to exercise all other
rights and remedies available at law or in equity. If the Borrower fails to pay
the Default Amount within five (5) business days of written notice that such
amount is due and payable, then the Holder shall have the right at any time, so
long as the Borrower remains in default (and so long and to the extent that
there are sufficient authorized shares), to require the Borrower, upon written
notice, to immediately issue, in lieu of the Default Amount, the number of
shares of Common Stock of the Borrower equal to the Default Amount divided by
the Conversion Price then in effect.

                           ARTICLE IV. MISCELLANEOUS

            4.1 FAILURE OR INDULGENCE NOT WAIVER. No failure or delay on the
part of the Holder in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such power, right or privilege preclude other or further exercise thereof or
of any other right, power or privileges. All rights and remedies existing
hereunder are cumulative to, and not exclusive of, any rights or remedies
otherwise available.

the Holder and the Borrower may change the address for service by service of
written notice to the other as herein provided.

            4.3 AMENDMENTS. This Note and any provision hereof may only be
amended by an instrument in writing signed by the Borrower and the Holder. The
term "Note" and all reference thereto, as used throughout this instrument, shall
mean this instrument (and the other Notes issued pursuant to the Purchase
Agreement) as originally executed, or if later amended or supplemented, then as
so amended or supplemented.

            4.4 ASSIGNABILITY. This Note shall be binding upon the Borrower and
its successors and assigns, and shall inure to be the benefit of the Holder and
its successors and assigns. Each transferee of this Note must be an "accredited

in this Note to the contrary, this Note may be pledged as collateral in
connection with a BONA FIDE margin account or other lending arrangement.

            4.5 COST OF COLLECTION. If default is made in the payment of this
Note, the Borrower shall pay the Holder hereof costs of collection, including
reasonable attorneys' fees.

            4.6 GOVERNING LAW. THIS NOTE SHALL BE ENFORCED, GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE, WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICT OF LAWS. THE BORROWER HEREBY SUBMITS TO THE

            4.7 CERTAIN AMOUNTS. Whenever pursuant to this Note the Borrower is
required to pay an amount in excess of the outstanding principal amount (or the
portion thereof required to be paid at that time) plus accrued and unpaid
interest plus Default Interest on such interest, the Borrower and the Holder
agree that the actual damages to the Holder from the receipt of cash payment on
this Note may be difficult to determine and the amount to be so paid by the
Borrower represents stipulated damages and not a penalty and is intended to
compensate the Holder in part for loss of the opportunity to convert this Note
and to earn a return from the sale of shares of Common Stock acquired upon
conversion of this Note at a price in excess of the price paid for such shares
pursuant to this Note. The Borrower and the Holder hereby agree that such amount
of stipulated damages is not plainly disproportionate to the possible loss to
the Holder from the receipt of a cash payment without the opportunity to convert
this Note into shares of Common Stock.

            4.8 ALLOCATIONS OF MAXIMUM SHARE AMOUNT AND RESERVED AMOUNT. The
Maximum Share Amount and Reserved Amount shall be allocated pro rata among the
Holders of Notes based on the principal amount of such Notes issued to each
Holder. Each increase to the Maximum Share Amount and Reserved Amount shall be
allocated pro rata among the Holders of Notes based on the principal amount of
such Notes held by each Holder at the time of the increase in the Maximum Share
Amount or Reserved Amount. In the event a Holder shall sell or otherwise
transfer any of such Holder's Notes, each transferee shall be allocated a pro
rata portion of such transferor's Maximum Share Amount and Reserved Amount. Any
portion of the Maximum Share Amount or Reserved Amount which remains allocated
to any person or entity which does not hold any Notes shall be allocated to the
remaining Holders of Notes, pro rata based on the principal amount of such Notes
then held by such Holders.

            4.9 DAMAGES SHARES. The shares of Common Stock that may be issuable
to the Holder pursuant to Sections 1.3 and 1.4(g) hereof and pursuant to Section
2(c) of the Registration Rights Agreement ("DAMAGES SHARES") shall be treated as
Common Stock issuable upon conversion of this Note for all purposes hereof and
shall be subject to all of the limitations and afforded all of the rights of the
other shares of Common Stock issuable hereunder, including without limitation,
the right to be included in the Registration Statement filed pursuant to the
Registration Rights Agreement. For purposes of calculating interest payable on
the outstanding principal amount hereof, except as otherwise provided herein,
amounts convertible into Damages Shares ("DAMAGES AMOUNTS") shall not bear
interest but must be converted prior to the conversion of any outstanding
principal amount hereof, until the outstanding Damages Amounts is zero.

            4.10 DENOMINATIONS. At the request of the Holder, upon surrender of
this Note, the Borrower shall promptly issue new Notes in the aggregate
outstanding principal amount hereof, in the form hereof, in such denominations
of at least $50,000 as the Holder shall request.

            4.11 PURCHASE AGREEMENT. By its acceptance of this Note, each Holder
agrees to be bound by the applicable terms of the Purchase Agreement.

            4.12 NOTICE OF CORPORATE EVENTS. Except as otherwise provided below,
the Holder of this Note shall have no rights as a Holder of Common Stock unless
and only to the extent that it converts this Note into Common Stock. The
Borrower shall provide the Holder with prior notification of any meeting of the
Borrower's shareholders (and copies of proxy materials and other information
sent to shareholders). In the event of any taking by the Borrower of a record of
its shareholders for the purpose of determining shareholders who are entitled to
receive payment of any dividend or other distribution, any right to subscribe
for, purchase or otherwise acquire (including by way of merger, consolidation,
reclassification or recapitalization) any share of any class or any other
securities or property, or to receive any other right, or for the purpose of
determining shareholders who are entitled to vote in connection with any
proposed sale, lease or conveyance of all or substantially all of the assets of
the Borrower or any proposed liquidation, dissolution or winding up of the
Borrower, the Borrower shall mail a notice to the Holder, at least twenty (20)
days prior to the record date specified therein (or thirty (30) days prior to
the consummation of the transaction or event, whichever is earlier), of the date
on which any such record is to be taken for the purpose of such dividend,
distribution, right or other event, and a brief statement regarding the amount
and character of such dividend, distribution, right or other event to the extent
known at such time. The Borrower shall make a public announcement of any event
requiring notification to the Holder hereunder substantially simultaneously with
the notification to the Holder in accordance with the terms of this Section
4.12.

            4.13 REMEDIES. The Borrower acknowledges that a breach by it of its
obligations hereunder will cause irreparable harm to the Holder, by vitiating
the intent and purpose of the transaction contemplated hereby. Accordingly, the
Borrower acknowledges that the remedy at law for a breach of its obligations
under this Note will be inadequate and agrees, in the event of a breach or
threatened breach by the Borrower of the provisions of this Note, that the
Holder shall be entitled, in addition to all other available remedies at law or
in equity, and in addition to the penalties assessable herein, to an injunction
or injunctions restraining, preventing or curing any breach of this Note and to
enforce specifically the terms and provisions thereof, without the necessity of
showing economic loss and without any bond or other security being required.

                             ARTICLE V. CALL OPTION

            5.1 CALL OPTION. Notwithstanding anything to the contrary contained
in this Article V, so long as (i) no Event of Default or Trading Market
Prepayment Event shall have occurred and be continuing, (ii) the Borrower has a
sufficient number of authorized shares of Common Stock reserved for issuance
upon full conversion of the Notes, then at any time after the Issue Date, and
(iii) the Common Stock is trading at or below $.11 per share, the Borrower shall
have the right, exercisable on not less than ten (10) Trading Days prior written
notice to the Holders of the Notes (which notice may not be sent to the Holders
of the Notes until the Borrower is permitted to prepay the Notes pursuant to
this Section 5.1), to prepay all of the outstanding Notes in accordance with
this Section 5.1. Any notice of prepayment hereunder (an "OPTIONAL PREPAYMENT")
shall be delivered to the Holders of the Notes at their registered addresses
appearing on the books and records of the Borrower and shall state (1) that the
Borrower is exercising its right to prepay all of the Notes issued on the Issue
Date and (2) the date of prepayment (the "OPTIONAL PREPAYMENT NOTICE"). On the
date fixed for prepayment (the "OPTIONAL PREPAYMENT DATE"), the Borrower shall
make payment of the Optional Prepayment Amount (as defined below) to or upon the
order of the Holders as specified by the Holders in writing to the Borrower at
least one (1) business day prior to the Optional Prepayment Date. If the
Borrower exercises its right to prepay the Notes, the Borrower shall make
payment to the holders of an amount in cash (the "OPTIONAL PREPAYMENT AMOUNT")
equal to either (i) 130% (for prepayments occurring within thirty (30) days of
the Issue Date), (ii) 140% for prepayments occurring between thirty-one (31) and
ninety (90) days of the Issue Date, or (iii) 150% (for prepayments occurring
after the ninetieth (90th) day following the Issue Date), multiplied by the sum
of (w) the then outstanding principal amount of this Note PLUS (x) accrued and
unpaid interest on the unpaid principal amount of this Note to the Optional
Prepayment Date PLUS (y) Default Interest, if any, on the amounts referred to in
clauses (w) and (x) PLUS (z) any amounts owed to the Holder pursuant to Sections
1.3 and 1.4(g) hereof or pursuant to Section 2(c) of the Registration Rights
Agreement (the then outstanding principal amount of this Note to the date of
payment PLUS the amounts referred to in clauses (x), (y) and (z) shall
collectively be known as the "OPTIONAL PREPAYMENT SUM"). Notwithstanding notice
of an Optional Prepayment, the Holders shall at all times prior to the Optional
Prepayment Date maintain the right to convert all or any portion of the Notes in
accordance with Article I and any portion of Notes so converted after receipt of
an Optional Prepayment Notice and prior to the Optional Prepayment Date set
forth in such notice and payment of the aggregate Optional Prepayment Amount
shall be deducted from the principal amount of Notes which are otherwise subject
to prepayment pursuant to such notice. If the Borrower delivers an Optional
Prepayment Notice and fails to pay the Optional Prepayment Amount due to the
Holders of the Notes within two (2) business days following the Optional
Prepayment Date, the Borrower shall forever forfeit its right to redeem the
Notes pursuant to this Section 5.1.
