     The  Debenture  set  forth  in  this  Agreement  is  subject  to  automatic
conversion  at the end of five (5) years from the date of issuance at which time
the Debenture outstanding will be automatically converted based upon the formula
set  forth  in  Section  3.2  (c).

Article  1          Interest

     The  Company  shall  pay ten percent (10%) annual coupon on the unpaid Face
Amount of this Debenture (this "Debenture") at such times and in such amounts as
determined  by  the Holder.  The Holder shall have the right to request interest
payments  on  the  Face  Amount anytime after closing and each month thereafter.
The  Holder  shall  submit  to  the Company a notice requesting a payment in the
amount  equal  to  the  interest  accruing  for that month on the balance of the
Debenture.  The  Interest  shall  be  compounded  daily.

     Any monies paid to the Holder in excess of the interest due when paid shall
be  credited  toward  the  Redemption  of  the  Face  Amount  of  the Debenture.

Article  2          Method  of  Payment

Section  2.1     Cash  Payments

     If  requested  by  the Holder, the Company will make amortizing payments to
the  Holder (a "Payment," or collectively, the "Payments") on a monthly basis on
the  first  day of each business day of each month while there is an outstanding
balance  on  the  Debenture, in an amount to be determined by the Holder and the
Company  based  on  the  Company's  then  current financial position.  ("Payment
Amount" or collectively, the "Payment Amounts").  In no event, shall the Payment
be  less than the Interest accruing on the outstanding balance of the Debenture.

Notwithstanding any provision to the contrary in this Debenture, the Company may
pay  in full to the Holder the Face Amount, or any balance remaining thereon, in
readily  available  funds,  at  any  time and from time to time without penalty.

     Section  2.2     Conversion  Payments

     The  Holder,  at  its sole option, shall be entitled to either i) request a
Payment from the Company in the amounts set forth in Section 2.1, above; or, ii)
the  Holder  may elect to convert a portion of the Debenture pursuant to Article
3,  below,  in  an  amount equal to or greater than the Payment Amount.   In the
event the Holder is unable to convert that portion of the debenture equal to the
Payment Amount during a calendar month, the Company shall make a payment in cash
in  an amount equal to the difference between the amount converted by the Holder
and  the  Payment  Amount  due  for  that  month.

     Nothing  contained  in this Article 2 shall limit the amount the Holder can
elect  to  convert during a calendar month except as defined in Section 3.2 (i),
below.

     All  Payments  made  in  under  Article  2,  shall  be  applied  toward the
Redemption  Amount  as  outlined  in  Article  14,  herein.

     Section  2.3  No  Penalty  for  Prepayment.

The  Company  may  make  additional  payments  toward  Redemption ("Prepayment")
without  any  penalties,  which  the  Holder  shall  have  the  right to refuse.

Section  2.4  Accelerated  Repayment in the Event of a Subsequent Financing by a
Third  Party.

If, at any time after Closing, the Company receives financing from a third party
(excluding the Holder), the Company is required to pay to the Holder 100% of the
proceeds  raised  from  the  third  party  in  excess  of an aggregate amount of
$500,000  (the  "Threshold Amount").  The Threshold Amount shall also pertain to
any  assets sold, transferred or disposed of by the Company.  The Company agrees
to pay one hundred percent (100%) of any proceeds raised by the Company over the
Threshold Amount toward the accelerated repayment of the Debenture with Interest
until  such time as the Face Amount of the Debenture has been paid in full.  The
accelerated  Repayment shall be made to the Holder upon the Company's receipt of
the  financing. Failure to do so will result in an Event of Default as set forth
herein.

Article  3          Conversion

Section  3.1     Conversion  Privilege

(a)     The Holder of this Debenture shall have the right to convert any and all
     amounts  owing under this Debenture 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 3.2(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)     This Debenture may not be converted, whether in whole or in part, except
     in  accordance  with  this  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)     Conversion Procedures. The unpaid Face Amount of and accrued interest on
     this Debenture may be converted, in whole or in part, at any time following
the Closing Date.  Such conversion shall be effectuated by the Holder sending to
the  Company  a  facsimile  or  electronic  mail version of the signed Notice of
Conversion  which  evidences  the  Holder's  intention  to convert the Debenture
indicated.  The date on which the Notice of Conversion is delivered ("Conversion
Date")  shall  be deemed to be the date on which the Holder has delivered to the
Company  a  facsimile  or  electronic  mail  of the signed Notice of Conversion.
Notwithstanding  the  above, any Notice of Conversion received by 5:00 P.M. EST,
shall  be  deemed  to have been received the previous business day, with receipt
being  via  a  confirmation  of  time  of  facsimile  of  the  Holder.

(b)     Common  Stock  to  be  Issued.     Upon  the  Holder's conversion of any
Debenture, the Company shall issue the number of shares of Common Stock equal to
     the  Conversion.  If, at the time of conversion, the Registration Statement
has  been  declared  effective, the Company shall instruct its transfer agent to
issue  stock  certificates  without  restrictive  legend  (other  than  a legend
referring  to  the  registration  statement and prospectus delivery requires) or
stop  transfer  instructions.  If  at  the  time  of  Holder's  conversion,  the
Registration  Statement  has  not  been  declared  effective,  the Company shall
instruct  the  transfer  agent  to  issue  the  certificates with an appropriate
legend.  The  Company  shall  act as Registrar and shall maintain an appropriate
ledger  containing the necessary information with respect to each Debenture. 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  otherwise set forth herein.

(c)     Conversion  Price.  Holder is entitled to convert the unpaid Face Amount
of  this Debenture, plus accrued interest, any time following a Closing Date, at
the  lesser  of  (i) 75% of the lowest closing bid price of the Common Stock for
the  fifteen  trading  day  period  prior to a Conversion; or, (ii) at forty-one
cents  ($.41).  The  lower  of  (i)  or  (ii) being referred to as a "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, as
the case may be, to the nearest whole share.  The Holder shall retain all rights
     of  conversions  during  any  partial  trading  days.

(d)     Maximum  Interest.  Nothing  contained in this Debenture shall be deemed
to  establish  or require the Company to pay 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,  if so ordered, shall be credited on any remaining balances due to
the  Holder  with  reasonable  promptness  by the Holder to the Company.  In the
event  this  Section  3.2  (d) applies, the Parties agree that the terms of this
Debenture  remain  in  full  force and effect except as is necessary to make the
interest  rate  comply  with  applicable  law.

(e)     Opinion  Letter.  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 or entity 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.

(f)     Delivery of Shares.  Within three (3) business days after receipt of the
     documentation  referred  to  above  in  Section  3.2(a),  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
three  (3)  business  days  after  the Conversion Date, the Company shall pay to
Holder  in cash, as liquidated damages, an additional three percent (3%) per day
of  the  dollar  value  of  the  Debentures  being  converted.

     If  the  failure  of the Company to issue the Common Stock pursuant to this
Section  3.2  (f)  is  due  to the unavailability of authorized shares of Common
Stock,  the  provisions of this Section 3.2 (f) shall not apply, but instead the
provisions  of  Section  3.2  (k)  shall  apply.

              The  Company  shall  make any payments required under this Section
3.2(f)  in  immediately  available funds within three (3) business days from the
date  the  Common  Stock  is  fully  delivered.  Nothing  herein shall limit the
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 three
(3)  business  days  after  the  Conversion  Date.

     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 Holder of the
entire  amount  of  Debentures  then  outstanding.  If,  at any time, the 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.  Any
Convertible  Debentures or any portion thereof, which cannot be converted due to
the  Company's  lack  of  sufficient  authorized  common stock (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 the Holder, by facsimile, within one (1)
business  days  of  such  default.

     In  the event of Conversion Default, the Company will pay to the Holder 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 that the Company authorizes
a  sufficient  number  of  shares  of  Common  Stock to effect conversion of all
remaining  Debentures (the "Authorization Date").  The Company shall send notice
to  Holder  of outstanding Debenture that additional shares of Common Stock have
been  authorized;  stating  the  Authorization  Date  and the amount of Holder's
accrued  Conversion  Default  Payments  ("Authorization  Notice").  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,  as  follows:   (i) in the event the Holder elects to take such payment
in  cash,  cash  payment  shall  be made to the Holder  within five (5) business
days,  or  (ii)  in  the  event Holder elects to take such payment in stock, the
Holder  may  convert  at  the conversion rate set forth in the first sentence of
this  paragraph  within  five  (5)  business  days  until  the expiration of the
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  Debenture  will  cause  the Holder to suffer irreparable harm, and that
damages  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.

     If,  by the third (3rd) business day after the Conversion Date, any portion
of  the  shares  of  the  Convertible  Debentures have not been delivered to the
Holder  and  the  Holder  purchases, in an open market transaction or otherwise,
shares  of  Common  Stock  (the "Covering Shares") necessary to make delivery of
shares  which  would  have been delivered if the full amount of the shares to be
converted and delivered to the Holder, then the Company shall pay to the Holder,
in  addition  to  any  other  amounts due to Holder pursuant to this Convertible
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.

(g)     Prospectus and Other Documents. 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.  Any  filings  submitted via EDGAR will constitute
fulfillment  of  the  Company's  obligation  under  this  Section.

(h)     Limitation  on Issuance of Shares. If the Company's Common Stock becomes
listed  on  the  Nasdaq SmallCap Market after the issuance of the Debenture, the
Company  may  be limited in the number of shares of Common Stock it may issue by
virtue  of  (A)  the number of authorized shares or (B) 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; (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 cannot convert 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 the 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 on
which  the  Redemption  Amount  is  paid  to the holder (the "Redemption Date").

     The  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 Debenture
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  Debenture.

(i)     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.

(j)     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, PURSUANT TO RULE 144 UNDER THE ACT (OR
ANY  SIMILAR  RULE UNDER SUCH ACT RELATING TO THE DISPOSITION OF SECURITIES), OR
(iii)  PURSUANT  TO  AN  AVAILABLE  EXEMPTION  FROM REGISTRATION UNDER SUCH ACT.

     (k)  Prior to conversion of the Debenture, if at any time 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  to an amount equal to three hundred percent (300%) of the balance
on  the DebentureThe Company represents and warrants that under no circumstances
will  it  deny  or  prevent  the  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 this Section 3.  The Holder, at his
option,  may request the company to authorize and issue additional shares if the
Holder  feels  it  is  necessary for conversions in the future. 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 the
sum of the principal of the outstanding Debentures plus accrued interest thereon
multiplied  by  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 by the Company 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     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 in shares
of  Common  Stock, the 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 of 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.

Article  4          Mergers
     The  Company shall not consolidate or merge into, or transfer any or 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  only upon such written assumption of the Company's obligation.
The  Company  shall  make  notice  to  the  Holder  simultaneously  with  the
dissemination  of  a  Merger  to  the  public  markets.

Article  5       Security

     This  Debenture  is  secured  by  both  Security  Agreements (the "Security
Agreements")  between  the Company and the Holder and its affiliates, both dated
September  19,  2005.

(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; or,

     (e)  the  Company's  Common  Stock  is suspended or no longer listed on any
recognized  exchange  including  electronic  over-the-counter  bulletin  board
("Principal  Market")  for  in  excess  of  three  (3) consecutive Trading Days.
Failure  to  comply  with  the requirements for continued listing on a Principal
Market  for  a period of five (5) trading days; or notification from a Principal
Market  that  the  Company  is  not  in  compliance with the conditions for such
continued  listing  on  such  Principal  Market;  or,

     (f)  the  Company  breaches  any  covenant  or condition of the Transaction

Section  6.2     Remedies.  In  the  Event  of  Default, the Holder may elect to
secure  a  portion  of the Company's assets in Pledged Collateral (as defined in
the Security Agreements).  The Holder may also elect to garnish Revenue from the
     Company  in  an amount that will repay the Holder on the schedules outlined
in  this  Agreement.

     In  the  Event  of  Default,  as outlined in this Agreement, the Holder can
exercise  its  right to increase the Face Amount of the Debenture by ten percent
(10%) as an initial penalty, and for each subsequent Event of Default under this
Agreement.  In addition, the Holder may elect to increase the Face Amount by two
and  one-half  percent (2.5%) per month (pro-rata for partial periods) paid as a
penalty  for liquated damages ("Liquidated Damages").  The Liquated Damages will
be  compounded  daily.  It  is the intention and acknowledgement of both parties
that  the  Liquidated  Damages not be deemed as interest under the terms of this
Agreement.

     The  Company  agrees that the date of consideration for the Debenture shall
remain  the  Issuance  Date stated herein.  The Company shall provide an opinion
letter  from  counsel  within  two  (2)  business days of written request by the
Holder  stating that the date of consideration for the Debenture is the Issuance
Date  and submission of proper Rule 144, promulgated under the Securities Act of
1933,  support  documentation  consisting of Form 144, a broker's representation
letter  and a seller's representation letter.  In the event the Company does not
deliver  the  opinion  letter  within  two business days, the Default Conversion
Price  shall  immediately  decrease by two percent (2%) for each business day an
opinion  letter fails to be delivered.  In the event that counsel to the Company
fails  or  refuses  to  render  an  opinion  as  required to issue the Shares in
accordance  with  this paragraph (either with or without restrictive legends, as
applicable),  then  the  Company irrevocably and expressly authorizes counsel to
the  Holder  to  render  such  opinion and shall authorize the Transfer Agent to
accept  and  to  rely  on  such  opinion  for the purposes of issuing the Shares
(which  is  attached  as  Exhibit  E  to  the Subscription Agreement between the
Company  and  the  Holder  of this date).  Any costs incurred by Holder for such
opinion  letter  shall  be  added  to  the  Face  Amount  of  the  Debenture.

Section  6.3     Acceleration.  If an Event of Default occurs, 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.

Section  6.4     Seniority.  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.  And, the Company warrants that it
has taken all necessary steps to subordinate its other obligations to the rights
of  the  Holder  hereunder.

     Section  6.5     Cost  of  Collections.  If an Event of Default occurs, the
Company  shall  pay  the Holder hereof reasonable costs of collection, including
reasonable  attorney's  fees.

Article  7          Registered  Debentures

Section  7.1     Record Ownership.  The Company, or its attorney, shall maintain
a  register of the Holder 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.

     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
Debenture  if  the  Holder  so  requests  by  written  notice  to  the  Company.

Article  8          Notice.

     Any  notices,  consents,  waivers  or  other  communications  required  or

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

negotiated,  executed,  delivered  and  performed  solely in the Commonwealth of
Massachusetts.

Article  13          Disputes  Under  Agreement

     All  disputes  arising  under  this  agreement  shall  be  governed  by and
interpreted  in  accordance  with the laws of the Commonwealth of Massachusetts,
without regard to principles of conflict of laws.  The parties to this agreement
will  submit all disputes arising under this agreement to arbitration in Boston,
Massachusetts before a single arbitrator of the American Arbitration Association
("AAA").  The  arbitrator  shall  be selected by application of the rules of the
AAA, or by mutual agreement of the parties, except that such arbitrator shall be
an  attorney  admitted to practice law in the Commonwealth of Massachusetts.  No
party  to  this agreement will challenge the jurisdiction or venue provisions as
provided  in  this  section.  Nothing  in  this section shall limit the Holder's
right  to  obtain  an  injunction for a breach of this Agreement from a court of
law.

Article  14  Redemption

     The  Holder  shall  have  the  right  to be redeemed from the Debenture, in
whole  or  in part, at a price equal to one hundred and twenty percent (120%) of
the  outstanding  principal  amount of the Debenture, including accrued interest
(and  penalties  if  applicable).  Any  Payments, as defined in Article 2 above,

following:  due  diligence  expenses, document creation expenses, closing costs,
and  transaction  administration  expenses.  This  shall  be  deducted  from the
Closing.

Article  17     Waiver

The  Holder's  delay or failure at any time or times hereafter to require strict
performance  by  the  Company of any undertakings, agreements or covenants shall
not  waive,  affect, or diminish any right of the Holder under this Agreement to
demand  strict  compliance and performance herewith. Any waiver by the Holder of
any  Event  of  Default  shall  not  waive or affect any other Event of Default,
whether  such Event of Default is prior or subsequent thereto and whether of the
same  or a different type. None of the undertakings, agreements and covenants of
the  Company  contained  in  this  Agreement,  and no Event of Default, shall be
deemed  to  have  been  waived by the Holder, nor may this Agreement be amended,
changed  or  modified,  unless such waiver, amendment, change or modification is
evidenced  by an instrument in writing specifying such waiver, amendment, change
or  modification  and  signed  by  the  Holder.

Article  18     Integration

This  Debenture  is  the FINAL AGREEMENT between the Company and the Holder with
respect  to  the  terms  and conditions set forth herein, and, the terms of this
Debenture  may  not  be  contradicted  by evidence of prior, contemporaneous, or
subsequent  oral  agreements of the Parties.  The execution and delivery of this
Debenture  shall  not alter the prior written agreements between the Company and
the  Holder.

Article  19     Failure  to  Meet  Obligations

           The  Company  acknowledges that its failure to timely meet any of its
obligations  hereunder,  including,  but without limitations, its obligations to
make  Payments,  deliver  shares  and,  as  necessary,  to register and maintain
sufficient  number  of  Shares, will cause the Holder to suffer irreparable harm
and,  that  the  actual  damage  to  the  Holder 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 do 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.

Article  20     Registration

     The  Company  shall  file  a registration statement with the SEC, within 45
days  following  a  written  request by the Holder ("Filing Date"), covering the
Debenture.  The  number of shares of Stock registered shall be equivalent to the
sum  of:  1) the Face Amount divided by the Conversion Price. The Company agrees
that  if  such  registration  statement has not been submitted to the SEC by the
Filing  Date,  the Conversion Price will initially drop ten percent (10%) and an
additional  ten  percent  (10%) for every fifteen (15) day period thereafter the
Company  fails to file the Registration Statement.  The Company also agrees that
if  the  Filing  Date  exceeds 45 days or the date the registration statement is
declared  effective  (the "Effective Date") exceeds 90 days from the Filing Date
("Penalty Date" collectively the "Penalty Dates"), a penalty of two percent (2%)
per  month, of the Face Amount of the Debenture, shall accrue for each month the
Filing  Date  and/or  the Effective Date exceeds the Penalty Date, pro-rated for
partial  periods.  The  Company  agrees not to include any other registration to
this  statement  without  the  Investor's  consent.

                                      *.*.*
