Million  Five  Hundred  Thousand  Dollars  ($1,500,000)  or, if  different,  the
aggregate  principal  amount of all Loans (as defined in the Security  Agreement
referred to below),  together with any accrued and unpaid  interest  hereon,  on
February 10, 2009 (the "Maturity Date") if not sooner paid.
     Capitalized  terms used herein without  definition  shall have the meanings
ascribed to such terms in the Security  Agreement  among the  Companies  and the
Holder dated as of the date hereof (as  amended,  modified  and/or  supplemented
from time to time, the "Security Agreement").
           The following terms shall apply to this Note (this "Note"):
                                    ARTICLE I
                                  CONTRACT RATE
     1.1 Contract Rate.  Subject to Sections 4.2 and 5.10,  interest  payable on
the outstanding  principal  amount of this Note (the  "Principal  Amount") shall
accrue at a rate per  annum  equal to the  "prime  rate"  published  in The Wall
Street  Journal from time to time (the "Prime  Rate"),  plus one percent  (1.0%)
(the "Contract Rate").  The Contract Rate shall be increased or decreased as the
case may be for each  increase or decrease in the Prime Rate in an amount  equal
to such  increase or decrease in the Prime Rate;  each change to be effective as
of the day of the change in the Prime Rate. Subject to Section 1.2, the Contract
Rate shall not at any time be less than eight percent (8.0%).  Interest shall be
(i)  calculated  on the basis of a 360 day year,  and (ii) payable  monthly,  in

consecutive  calendar month  thereafter  through and including the Maturity Date
and on the Maturity Date, whether by acceleration or otherwise.
                                       1
     1.2 Contract  Rate and  Payments.  The Contract Rate shall be calculated on
the last business day of each calendar month hereafter (other than for increases
or decreases in the Prime Rate which shall be calculated and become effective in
accordance  with the terms of  Section  1.1)  until the  Maturity  Date  (each a
"Determination Date")
                                   ARTICLE II
                         LOANS; PAYMENTS UNDER THIS NOTE
     2.1 Loans.  All Loans  evidenced  by this Note shall be made in  accordance
with the terms and provisions of the Security Agreement.
     2.2 No  Effective  Registration.  Notwithstanding  anything to the contrary
herein,  the Holder  shall not be required to accept  shares of Common  Stock as
payment  following  a  conversion  by the  Holder  if  there  fails  to exist an
effective current Registration  Statement (as defined in the Registration Rights
Agreement)  covering the shares of Common Stock to be issued,  or if an Event of
Default hereunder exists and is continuing, unless such requirement is otherwise
waived in writing by the Holder in whole or in part at the Holder's option.
     2.3 Optional  Redemption  in Cash.  The  Companies  will have the option of
prepaying  this Note  ("Optional  Redemption")  by paying to the Holder a sum of
money equal to i) one hundred thirty  percent (130%) of the principal  amount of
this Note  together  with  accrued but unpaid  interest  thereon and any and all
other sums due,  accrued or payable to the Holder  arising under this Note,  the
Security Agreement,  or any other Ancillary Agreement if such redemption is made
on or before  February 10, 2007;  ii) one hundred  twenty five percent (125%) of
the  principal  amount of this Note  together  with accrued but unpaid  interest
thereon and any and all other sums due, accrued or payable to the Holder arising
under this Note, the Security  Agreement,  or any other  Ancillary  Agreement if
such  redemption is made after  February 10, 2007 but on or before  February 10,
2008 or iii) one hundred twenty  percent (120%) of the principal  amount of this
Note  together  with accrued but unpaid  interest  thereon and any and all other
sums due, accrued or payable to the Holder arising under this Note, the Security
Agreement,  or any other  Ancillary  Agreement if such  redemption is made after
February  10,  2008 but on or before  February  10,  2009 (each such  respective
amount being a "Redemption  Amount")  outstanding on the Redemption Payment Date
(as defined below).  The Company shall deliver to the Holder a written notice of
redemption  (the "Notice of  Redemption")  specifying the date for such Optional
Redemption (the "Redemption  Payment Date"),  which date shall be seven (7) days
after the date of the Notice of Redemption (the "Redemption  Period").  A Notice
of  Redemption  shall not be effective  with respect to any portion of this Note
for which the Holder has  previously  delivered a Notice of Conversion  (defined
below)  pursuant to Section  3.1, or for  conversions  elected to be made by the
Holder  pursuant to Section 3.1 during the  Redemption  Period.  The  Redemption
Amount shall be  determined as if such  ▇▇▇▇▇▇'s  conversion  elections had been
completed  immediately  prior to the date of the  Notice of  Redemption.  On the
Redemption Payment Date, the Redemption Amount (plus any additional interest and
fees  accruing on the Notes during the  Redemption  Period) must be  irrevocably
paid in full in  immediately  available  funds to the  Holder.  In the event the
Companies fail to pay the Redemption Amount on the Redemption Payment Date, then
such Redemption Notice shall be null and void.
                                       2
                                  ARTICLE III
                  CONVERSION RIGHTS AND FIXED CONVERSION PRICE
     3.1  Optional  Conversion.  Subject to the terms of this  Article  III, the
Holder  shall  have the  right,  but not the  obligation,  at any time until the
Maturity  Date,  or during an Event of Default (as defined in Article IV),  and,
subject to the  limitations  set forth in Section 3.2 hereof,  to convert all or
any portion of the outstanding Principal Amount and/or accrued interest and fees
due and payable into fully paid and nonassessable  shares of the Common Stock at
the Fixed Conversion Price. For purposes hereof,  subject to Section 3.6 hereof,
the initial "Fixed  Conversion Price" means $0.91. The shares of Common Stock to
be  issued  upon such  conversion  are  herein  referred  to as the  "Conversion
Shares."
     3.2 Conversion Limitation. Notwithstanding anything contained herein to the
contrary,  the Holder shall not be entitled to convert  pursuant to the terms of
this Note an amount that would be  convertible  into that  number of  Conversion
Shares which would exceed the  difference  between (i) 9.99% of the  outstanding
shares  of  Common  Stock  and  (ii)  the  number  of  shares  of  Common  Stock
beneficially  owned by the Holder.  For  purposes of the  immediately  preceding
sentence,  beneficial  ownership  shall be determined in accordance with Section
13(d) of the Exchange Act and Regulation 13d-3 thereunder. The Conversion Shares
limitation  described  in this Section 3.2 shall  automatically  become null and
void  following  notice  to the  Parent  upon  the  occurrence  and  during  the
continuance of an Event of Default,  upon 75 days prior notice to the Parent, or
upon receipt by the Holder of a Notice of Redemption.  Notwithstanding  anything
contained  herein  to the  contrary,  the  provisions  of this  Section  3.2 are
irrevocable and may not be waived by the Holder or any Company.
     3.3 Mechanics of ▇▇▇▇▇▇'s  Conversion.  In the event that the Holder elects
to convert  this Note into Common  Stock,  the Holder  shall give notice of such
election  by  delivering  an  executed  and  appropriately  completed  notice of
conversion  in   substantially   the  form  of  Exhibit  B  hereto  ("Notice  of
Conversion")  to the  Parent  and such  Notice  of  Conversion  shall  provide a
breakdown in reasonable  detail of the  Principal  Amount and accrued and unpaid
interest  and  fees  that  are  being  converted.  On each  Conversion  Date (as
hereinafter defined) and in accordance with its Notice of Conversion, the Holder
shall make the  appropriate  reduction to the  Principal  Amount and accrued and
unpaid  interest  and fees as entered in its records and shall  provide  written
notice  thereof to the Parent within two (2) Business Days after the  Conversion
Date.  Each date on which a Notice of  Conversion  is delivered or telecopied to
the Parent in accordance with the provisions hereof shall be deemed a Conversion
Date (the "Conversion Date"). Pursuant to the terms of the Notice of Conversion,
the Parent will issue  instructions  to the  transfer  agent  accompanied  by an
opinion of counsel  within two (2) Business  Days of the date of the delivery to
the Parent of the Notice of  Conversion  and shall cause the  transfer  agent to
transmit the certificates  representing  the Conversion  Shares to the Holder by
crediting  the account of the  Holder's  designated  broker with the  Depository
Trust  Corporation  ("DTC")  through its  Deposit  Withdrawal  Agent  Commission
("DWAC")  system within [three (3) Business Days] after receipt by the Parent of
the Notice of Conversion (the "Delivery  Date").  In the case of the exercise of
the conversion rights set forth herein the conversion  privilege shall be deemed
to have been exercised and the Conversion  Shares  issuable upon such conversion
shall be deemed to have been  issued  upon the date of  receipt by the Parent of
                                       3
the Notice of  Conversion.  The Holder  shall be treated for all purposes as the
record holder of the Conversion  Shares,  unless the Holder  provides the Parent
written instructions to the contrary.
     3.4 Late Payments. Each Company understands that a delay in the delivery of
the Conversion  Shares in the form required  pursuant to this Article beyond the
Delivery Date could result in economic loss to the Holder.  As  compensation  to
the Holder for such loss, in addition to all other rights and remedies which the
Holder may have under this Note,  applicable  law or  otherwise,  the  Companies
shall,  jointly  and  severally,  pay late  payments  to the Holder for any late
issuance of Conversion  Shares in the form required pursuant to this Article III
upon conversion of this Note, in the amount equal to $500 per Business Day after
the Delivery Date. The Companies shall, jointly and severally, make any payments
incurred under this Section in immediately available funds upon demand.
     3.5 Conversion Mechanics. The number of shares of Common Stock to be issued
upon each  conversion  of this Note shall be determined by dividing that portion
of the  principal  and  interest and fees to be  converted,  if any, by the then
applicable Fixed Conversion Price.
     3.6 Adjustment  Provisions.  The Fixed Conversion Price and number and kind
of shares or other securities to be issued upon conversion  determined  pursuant
to  Section  3.1  shall be  subject  to  adjustment  from  time to time upon the
occurrence  of  certain  events  during the period  that this  conversion  right
remains outstanding, as follows:
          (a)   Reclassification.   If  the  Parent  at  any  time   shall,   by
reclassification  or  otherwise,  change  the  Common  Stock  into the same or a
different  number of  securities  of any class or classes,  this Note, as to the
unpaid Principal Amount and accrued interest thereon, shall thereafter be deemed
to evidence the right to purchase an adjusted number of such securities and kind
of  securities  as would have been  issuable  as the result of such  change with
respect to the Common Stock (i) immediately  prior to or (ii) immediately  after
such reclassification or other change at the sole election of the Holder.
          (b) Stock Splits,  Combinations and Dividends. If the shares of Common
Stock are  subdivided or combined into a greater or smaller  number of shares of
Common  Stock,  or if a dividend  is paid on the Common  Stock or any  preferred
stock issued by the Parent in shares of Common Stock, the Fixed Conversion Price
shall be  proportionately  reduced  in case of  subdivision  of  shares or stock
dividend or  proportionately  increased in the case of combination of shares, in
each  such case by the ratio  which the total  number of shares of Common  Stock
outstanding  immediately after such event bears to the total number of shares of
Common Stock outstanding immediately prior to such event.
     3.7 Reservation of Shares.  During the period the conversion  right exists,
the  Parent  will  reserve  from its  authorized  and  unissued  Common  Stock a
sufficient  number of shares to provide for the  issuance of  Conversion  Shares
                                       4
upon the full conversion of this Note and the Option. The Parent represents that
upon issuance, the Conversion Shares will be duly and validly issued, fully paid
and  non-assessable.  The Parent  agrees  that its  issuance  of this Note shall
constitute full authority to its officers,  agents,  and transfer agents who are
charged with the duty of executing and issuing stock certificates to execute and
issue the necessary  certificates for the Conversion  Shares upon the conversion
of this Note.
     3.8 Registration  Rights. The Holder has been granted  registration  rights
with  respect to the  Conversion  Shares as set forth in a  Registration  Rights
Agreement.
     3.9 Issuance of New Note.  Upon any partial  conversion of this Note, a new
Note  containing the same date and provisions of this Note shall, at the request
of the Holder,  be issued by the Parent to the Holder for the principal  balance
of this Note and accrued  interest  which shall not have been converted or paid.
Subject to the  provisions of Article IV of this Note,  the Parent shall not pay
any costs, fees or any other  consideration to the Holder for the production and
issuance of a new Note.
                                   ARTICLE IV
                EVENTS OF DEFAULT AND DEFAULT RELATED PROVISIONS
     4.1 Events of  Default.  The  occurrence  of an Event of Default  under the
Security  Agreement  shall  constitute an event of default  ("Event of Default")
hereunder.
     4.2 Default  Interest.  Following the occurrence and during the continuance
of an  Event of  Default,  the  Companies  shall,  jointly  and  severally,  pay
additional  interest  on the  outstanding  principal  balance of this Note in an
amount equal to two percent  (2%) per month,  and all  outstanding  Obligations,
including unpaid interest,  shall continue to accrue interest at such additional
interest  rate from the date of such Event of Default  until the date such Event
of Default is cured or waived. In the event, an Event of Default is occuring for
a partial month, the default interest rate should only apply for such period.
     4.3 Default Payment. Following the occurrence and during the continuance of
an Event of Default,  the Holder,  at its option,  may elect, in addition to all
rights and remedies of the Holder under the Security Agreement and the Ancillary
Agreements and all obligations of each Company under the Security  Agreement and
the Ancillary Agreements,  to require the Companies,  jointly and severally,  to
make a Default Payment ("Default Payment"). The Default Payment shall be 120% of
the outstanding  principal amount of the Note, plus accrued but unpaid interest,
all other fees then remaining unpaid,  and all other amounts payable  hereunder.
The Default  Payment  shall be applied  first to any fees due and payable to the
Holder  pursuant to the Notes and/or the Ancillary  Agreements,  then to accrued
and unpaid  interest due on the Notes,  the Security  Agreement  and then to the
outstanding principal balance of the Notes. The Default Payment shall be due and
payable  immediately  on the date  that the  Holder  has  exercised  its  rights
pursuant to this Section 4.3.
                                   ARTICLE V
                                 MISCELLANEOUS

III shall remain in full force and effect immediately from the date hereof until
the date this Note is indefeasibly paid in full and irrevocably terminated.
     5.2 Cumulative Remedies.  The remedies under this Note shall be cumulative.
     5.3 Failure or  Indulgence  Not Waiver.  No failure or delay on the part of
the Holder  hereof 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  privilege.  All  rights  and  remedies  existing
hereunder  are  cumulative  to, and not  exclusive  of,  any rights or  remedies
otherwise available.

Holder may  designate by ten days advance  written  notice to the other  parties
hereto.
     5.5 Amendment  Provision.  The term "Note" and all references  thereto,  as
used  throughout  this  instrument,  shall mean this  instrument  as  originally
executed,  or  if  later  amended  or  supplemented,   then  as  so  amended  or

     5.6  Assignability.  This Note shall be binding  upon each  Company and its
successors  and  assigns,  and shall  inure to the benefit of the Holder and its
successors and assigns, and may be assigned by the Holder in accordance with the

such purported assignment without such consent being null and void.

EACH  COMPANY  ACKNOWLEDGES  THAT ANY APPEALS  FROM THOSE  COURTS MAY HAVE TO BE
HEARD BY A COURT LOCATED  OUTSIDE OF THE COUNTY OF NEW YORK,  STATE OF NEW YORK;
AND FURTHER  PROVIDED,  THAT  NOTHING IN THIS NOTE SHALL BE DEEMED OR OPERATE TO
PRECLUDE THE HOLDER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER
JURISDICTION  TO COLLECT THE  OBLIGATIONS,  TO REALIZE ON THE  COLLATERAL OR ANY
OTHER  SECURITY  FOR THE  OBLIGATIONS,  OR TO ENFORCE A JUDGMENT  OR OTHER COURT

APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE
BENEFITS OF THE JUDICIAL SYSTEM AND OF  ARBITRATION,  EACH COMPANY HERETO WAIVES
ALL  RIGHTS TO TRIAL BY JURY IN ANY  ACTION,  SUIT,  OR  PROCEEDING  BROUGHT  TO
RESOLVE ANY DISPUTE, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE BETWEEN THE
HOLDER, AND/OR ANY COMPANY ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL

SECURITY AGREEMENT,  ANY OTHER ANCILLARY  AGREEMENT OR THE TRANSACTIONS  RELATED
HERETO OR THERETO.
     5.9  Severability.  In the event that any provision of this Note is invalid
or  unenforceable  under  any  applicable  statute  or rule of  law,  then  such
provision  shall  be  deemed  inoperative  to the  extent  that it may  conflict
