advance,  on  the  interest  ("Interest  Payment"),  with  the  minimum Interest

     Any monies paid to the Holder in excess of the interest due when paid shall

     Section  2.1     Prior  to  the  U.S.  Securities  and  Exchange Commission
("SEC")  declaring  the  registration  statement  for  the shares underlying the
Debenture  ("Registration  Statement")  effective  ("Effective  Date").

     Amortizing  payments  will  be  made by the Company in satisfaction of this
Debenture  (each  a  "Payment,"  and collectively, the "Payments") shall be made
monthly  on  the  twenty-ninth  (29th)  day of each month, or the next available

option, shall be entitled to either a) request a Payment from the Company in the
amounts set forth in the table in Section 2.1 above; or, b) the Holder may elect

equal to 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 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)

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

Article  3          Conversion

Section  3.1     Conversion  Privilege

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

(b)     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  Face  Amount  of  this  Debenture  may  be
converted,  in  whole  or  in  part,  any time following the Closing Date.  Such
conversion  shall  be  effectuated  by sending to the Company a facsimile or via
electronic  mail  of  the  signed  Notice of Conversion which evidences Holder's
intention  to  convert the Debenture indicated.  The date on which the Notice of
Conversion  is  effective  ("Conversion Date") shall be deemed to be the date on
which  the  Holder has delivered to the Company a facsimile of the signed Notice
of  ConversionNotwithstanding  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 conversion of any Debenture and
upon  receipt  by  the  Company  of  a  facsimile  of  Holder's signed Notice of
Conversion  the  Company  shall  instruct  its  transfer  agent  to  issue stock
certificates  without  restrictive  legend  or stop transfer instructions, if at
that time the Registration Statement has been declared effective (or with proper
     restrictive  legend  if  the  Registration  Statement  has  not as yet been
declared  effective),  in  such  denominations  to  be  specified  at conversion
representing the number of shares of Common Stock issuable upon such conversion,
as  applicable.   The  Company  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 set forth
herein.

(c)     Conversion  Rate.  Holder is entitled to convert the Face Amount of this
Debenture,  plus  accrued  interest,  anytime following the Closing Date, at the
lesser of (i)  the lowest closing bid price during the fifteen (15) days of full
     trading,  defined  as  standard  market  hours from 9:30 AM to 4:00 PM EST,
partial trading days will not be counted for calculation purposes only ("Trading
Days")  prior to the Filing Date; or (ii) one dollar ($1.00). ("Fixed Conversion
Price"), also being referred to as the "Conversion Price".  No fractional shares
or  scrip representing fractions of shares will be issued on conversion, but the
number  of  shares  issuable  shall  be  rounded  up, as the case may be, to the
nearest  whole  share.  The Holder shall retain all rights of conversions during
any  partial  trading  days.

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

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

(f)     Within  five  (5)  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 five (5) business days
after  the  Conversion  Date, then in such event the Company shall pay to Holder
three  percent  (3%)  in  cash,  of  the  dollar  value  of the Debentures being
converted,  compounded  daily,  per  each day after the third (3rd) business day
following  the  Conversion  Date  that  the Common Stock is not delivered to the
Purchaser,  as  liquidated  damages.

                The  Company acknowledges that its failure to deliver the Common
Stock  within  five  (5)  business days after the Conversion Date will cause the
Holder  to  suffer  damages  in  an  amount that will be difficult to ascertain.
Accordingly,  the  parties  agree  that  it  is  appropriate  to include in this
Debenture a provision for liquidated damages.  The parties acknowledge and agree
that  the  liquidated damages provision set forth in this section represents the
parties' good faith effort to quantify such damages and, as such, agree that the
form  and  amount  of  such  liquidated  damages  are  reasonable  and  will not
constitute  a  penalty.  The payment of liquidated damages shall not relieve the
Company  from  its obligations to deliver the Common Stock pursuant to the terms
of  this  Debenture.

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

              The  Company  shall  make any payments incurred 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 a Holder's
right  to  pursue  actual  damages  or  cancel  the conversion for the Company's
failure to issue and deliver Common Stock to the Holder within five (5) business
days  after  the  Conversion  Date.

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

     The Company agrees to pay to Holder of outstanding Debenture payments for a
Conversion  Default  ("Conversion  Default Payments") in the amount of (N/365) x
(.24)  x  the  initial issuance price of the outstanding and/or tendered but not
converted  Debentures  held by each Holder where N = the number of days from the
Conversion  Default Date to the date (the "Authorization Date") that the Company
authorizes a sufficient number of shares of Common Stock to effect conversion of
all  remaining  Debentures.  The  Company  shall  send  notice  ("Authorization
Notice")  to  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.  The accrued Conversion Default
shall  be  paid  in  cash  or  shall  be  convertible  into  Common Stock at the
Conversion  Rate,  upon  written notice sent by the Holder to the Company, which
Conversion  Default shall be payable as follows:  (i) in the event Holder elects
to  take  such  payment  in  cash, cash payments shall be made to such Holder of
outstanding  Debentures  by the fifth (5th) day of the following calendar month,
or (ii) in the event Holder elects to take such payment in stock, the Holder may
convert such payment amount into Common Stock  at  the conversion rate set forth
in  Section  3.2(c)  at any time after the fifth (5th) day of the calendar month
following  the  month  in which the Authorization Notice was received, until the
expiration  of  the  mandatory  five  (5)  year  conversion  period.

     The  Company  acknowledges that its failure to maintain a sufficient number
of authorized but unissued shares of Common Stock to effect in full a conversion
of  the Debenture will cause the Holder to suffer damages in an amount that will
be  difficult  to  ascertain.  Accordingly,  the  parties  agree  that  it  is
appropriate  to  include  in  this Agreement a provision for liquidated damages.
The  parties  acknowledge  and  agree  that the liquidated damages provision set
forth in this section represents the parties' good faith effort to quantify such
damages  and, as such, agree that the form and amount of such liquidated damages
are  reasonable  and  will  not constitute a penalty.  The payment of liquidated
damages shall not relieve the Company from its obligations to deliver the Common
Stock  pursuant  to the terms of this Debenture.  Nothing herein shall limit the
Holder's  right to pursue actual damages for the Company's failure to maintain a
sufficient  number  of  authorized  shares  of  Common  Stock.

     If,  by  the  third  (3rd)  business  day  after the Conversion Date of any
portion  of  the  Debenture  to be converted (the "Delivery Date"), the transfer
agent  fails  for  any reason to deliver the Common Stock upon conversion by the
Holder  and  after  such  Delivery Date, the Holder purchases, in an open market
transaction  or otherwise, shares of Common Stock (the "Covering Shares") solely
in  order  to  make  delivery  in  satisfaction of a sale of Common Stock by the
Holder (the "Sold Shares"), which delivery such Holder anticipated to make using
the Common Stock issuable upon conversion (a "Buy-In"), the Company shall pay to
the  Holder,  in  addition  to  any other amounts due to Holder pursuant to this
Debenture,  and  not  in  lieu thereof, the Buy-In Adjustment Amount (as defined
below).  The  "Buy  In  Adjustment Amount" is the amount equal to the excess, if
any,  of (x) the Holder's total purchase price (including brokerage commissions,
if  any)  for  the  Covering  Shares  over (y) the net proceeds (after brokerage
commissions,  if  any)  received by the Holder from the sale of the Sold Shares.
The  Company shall pay the Buy-In Adjustment Amount to the Holder in immediately
available  funds within three (3) 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.

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

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

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

     A  holder  of  an Unconverted Debenture may elect one of the above remedies
with  respect  to  a  portion of such Unconverted Debenture and the other remedy
with  respect  to  other  portions  of the Unconverted Debenture.  The 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, RULE 144 UNDER THE ACT (OR ANY SIMILAR
RULE  UNDER  SUCH ACT RELATING TO THE DISPOSITION OF SECURITIES), OR (iii) IF AN
EXEMPTION  FROM  REGISTRATION  UNDER  SUCH  ACT  IS  AVAILABLE.

     (m)  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.  The  Company represents and warrants that under no circumstances
will  it  deny  or prevent Holder's right to convert the Debentures as permitted
under  the  terms  of  this  Subscription  Agreement  or the Registration Rights
Agreement.  Nothing in this Section shall limit the obligation of the Company to
make the payments set forth in Section 3.2(g).  The investor, at his option, may
request  the  company  to  authorize and issue additional shares if the investor
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 (x) the
sum of the principal of the outstanding Debentures plus accrued interest thereon
multiplied  by  (y)  133%.

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

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

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

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


Article  4          Mergers
     The  Company  shall  not  consolidate  or  merge  into,  or transfer all or
substantially  all  of  its assets to, any person, unless such person assumes in
writing  the  obligations  of  the  Company under this Debenture and immediately
after  such transaction no Event of Default exists.  Any reference herein to the
Company  shall  refer  to  such  surviving  or  transferee  corporation  and the
obligations  of  the  Company  shall  terminate  upon  such  written assumption.

Article  5       Security

     This  Debenture  is  secured  by  a  Security  Agreement  (the  "Security
Agreement")  of  even  date  herewith  between  the  Company  and  the  Holder.

Article  6          Defaults  and  Remedies

Section  6.1  Events of Default. An "Event of Default" occurs if (a) the Company
does  not make the Payment of the principal of this Debenture by conversion into
Common Stock within five (5) business days of the Maturity Date, upon redemption
or  otherwise,  (b) the Company does not make a payment, other than a payment of
principal,  for  a  period of three (3) business days thereafter, (c) any of the
Company's  representations or warranties contained in the Subscription Agreement

appointment  of  a  Custodian  (as  hereinafter  defined)  of  it  or for all or
substantially  all  of  its  property or (iv) makes a general assignment for the
benefit  of  its  creditors  or  (v) a court of competent jurisdiction enters an
order  or  decree  under  any Bankruptcy Law that: (A) is for relief against the
Company  in  an involuntary case; (B) appoints a Custodian of the Company or for
all  or  substantially  all of its property or (C) orders the liquidation of the
Company,  and  the order or decree remains unstayed and in effect for sixty (60)
calendar  days,  (e) the Company's Common Stock is suspended or no longer listed
on  any recognized exchange including electronic over-the-counter bulletin board
for  in excess of five (5) consecutive Trading Days (e) the Company violates any
terms  and  conditions of the Registration Rights Agreement (f) the Registration
Statement  underlying  the Debenture is not declared effective by the SEC within
twelve  (12)  months  of  the  Issuance  Date.

As  used  in  this  Section 6.1, the term "Bankruptcy Law" means Title 11 of the
United  States  Code  or  any  similar  federal  or  state law for the relief of
debtors.  The term "Custodian" means any receiver, trustee, assignee, liquidator
or  similar official under any Bankruptcy Law.  A default under clause (c) above
is  not  an  Event  of Default until the holders of at least one hundred percent
(100%)  of  the  aggregate principal amount of the Debentures outstanding notify
the  Company  of  such  default and the Company does not cure it within five (5)
business  days after the receipt of such notice, unless the Company commences to
cure  such  default  within  such period, which must specify the default, demand
that  it  be  remedied  and state that it is a "Notice of Default". Prior to the
expiration  of  the  time  for  curing  a  default as set forth in the preceding
sentence,  the  holders  of  a  majority  in  aggregate  principal amount of the
Debentures  at  the  time outstanding (exclusive of Debentures then owned by the
Company  or any subsidiary or affiliate) may, on behalf of the holders of all of
the  Debentures,  waive  any  past Event of Default hereunder (or any past event
which,  with  the  lapse  of  time  or  notice  and  lapse of time designated in
subsection  (a),  would  constitute  an  Event  of  Default  hereunder)  and its
consequences, except a default in the payment of the principal of or interest on
any  of the Debentures. In the case of any such waiver, such default or Event of
Default  shall  be deemed to have been cured for every purpose of this Debenture
and  the  Company  and  the holders of the Debentures shall be restored to their
former  positions  and  rights hereunder, respectively; but no such waiver shall
extend  to  any  subsequent  or  other  default  or  impair any right consequent
thereon.

          In  the  Event of Default, the Holder may elect to secure a portion of
the  Company's  assets  not  to  exceed 200% of the Face Amount of the Note,  in
Pledged  Collateral  (as  defined  in the Irrevocable Transfer Agent Agreement).
The  Holder  may  also  elect to garnishee 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 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.

          In  the  event of Default, specifically to Section 6.1 (f), the Holder
may elect to switch the Conversion Price of the Debenture as outlined in Section
3.2  (c) above ("Default Conversion Price").  The Default Conversion Price shall
be  equal  to  the lesser of a) the Fixed Conversion Price or b) seventy percent
(70%)  of  the  lowest  closing bid price of the Common Stock during the fifteen
(15)  trading  days  prior to conversion.  Upon written notice being sent to the
Company  by  the  Holder  of  Default  under  Section  6.1 (f), and the Holder's
election  to  exercise  the remedy to switch the conversion price to the Default
Conversion  Price,  the  Company  shall  immediately  withdraw  the Registration
Statement.  Further,  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) days of written request by
the  Holder  stating  that  the  date  of consideration for the Debenture is the
Issuance  Date.  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 Investor to render such
opinion  and  shall authorize the Transfer Agent shall accept and be entitled to
rely on such opinion for the purposes of issuing the Shares.  Any costs incurred
by  Holder  for  such  opinion  letter  shall be added to the Face Amount of the
Debenture.


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

Section 6.3     Seniority, No past 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.  The Company shall be able to
secure  specific  property  or  equipment  for  the continuing operations of the
Company.

Article  7          Registered  Debentures

Section  7.1     Record Ownership.  The Company, or its attorney, shall maintain
a register of the holders of the Debentures (the "Register") showing their names
     and  addresses  and  the serial numbers and principal amounts of Debentures
issued to them.  The Register may be maintained in electronic, magnetic or other
computerized form.  The Company may treat the person named as the Holder of this

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 actually received by the Company before it is notified that the
Debenture  has  been  acquired  by  a  bona  fide  purchaser  and the Holder has
delivered  to  the  Company  an indemnity bond in such amount and issued by such
surety  as  the  Company  deems  satisfactory  together with an affidavit of the
Holder  setting  forth  the  facts concerning such loss, destruction or wrongful
taking  and  such other information in such form with such proof or verification
as  the  Company  may  request.
