                          SECURED CONVERTIBLE DEBENTURE

Englewood,  Colorado
January  31,  2002                                                      $_______

     FOR  VALUE  RECEIVED,  MARKETCENTRAL.NET  CORP.,  a  Texas  corporation
(hereinafter  called the "BORROWER"), hereby promises to pay to the order of ___
_______________ or registered assigns (the "HOLDER") the sum of ________________
Dollars  ($______),  on  January  31,  2003  (the  "MATURITY  DATE"), and to pay
interest  on  the  unpaid principal balance hereof at the rate of twelve percent
(12%)  per annum from January 31, 2002 (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 Debenture 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, at the
option  of  the  Holder, either quarterly on March 31, June 30, September 30 and
December  31  of  each  year  beginning  on  March  31,  2002, or at the time of
conversion  of  the  principal to which such interest relates in accordance with
Article  I  below.  All payments due hereunder (to the extent not converted into
common  stock, par value $0.0001 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  or,  at  the  option of the Holder, in whole or in part, in
shares  of Common Stock of the Borrower valued at the then applicable Conversion
Price  (as  defined  herein).  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 Debenture.  Whenever any amount expressed to be due
by  the  terms  of this Debenture 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  Debenture 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 Debenture, 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  January  31,  2002,  pursuant  to  which  this  Debenture was
originally  issued  (the  "PURCHASE  AGREEMENT").

     This  Debenture 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  stockholders  of  the  Borrower  and will not impose
personal  liability  upon  the  holder thereof.  The obligations of the Borrower
under  this  Debenture shall be secured by that certain Security Agreement dated
by  and  between  the  Borrower  and  the  Holder  of  even  date  herewith.

     The  following  terms  shall  apply  to  this  Debenture:


                          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 Debenture to convert all
or  any  part  of  the outstanding and unpaid principal amount of this Debenture
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 Debenture in excess of that
portion  of this Debenture 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 Debentures 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 Debenture 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  Holder  of  this  Debenture  may waive the
limitations  set  forth  herein  by  sixty-one  (61)  days written notice to the
Company.  The number of shares of Common Stock to be issued upon each conversion
of  this  Debenture  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 Debenture, the sum of (1) the
principal  amount  of this Debenture 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  Debenture  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 January 31, 2002,
executed in connection with the initial issuance of this Debenture and the other
Debentures  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 Debentures 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 Debentures being converted for which the calculation of the Trading Price is
required  in  order  to  determine  the  Conversion  Price  of  such Debentures.
"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  50.0%.  The  "FIXED  CONVERSION  PRICE"  shall  mean  $0.075.

     (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.

     1.3     AUTHORIZED  SHARES.  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  Debenture  and  the  other  Debentures  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 Debentures (based on the Conversion Price of the Debentures 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
Debentures  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 Debentures.  The
Borrower  (i) acknowledges that it has irrevocably instructed its transfer agent
to  issue  certificates  for  the  Common Stock issuable upon conversion of this
Debenture,  and (ii) agrees that its issuance of this Debenture 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
Debenture.

     If,  at any time a Holder of this Debenture 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 Debenture
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 Debenture plus (2)
     ------                                                             ----
accrued  and  unpaid  interest  on the unpaid principal amount of this Debenture
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 Debenture.  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 Holder's option, as follows:

     (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  9:00 p.m., 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 Debenture
             -----------------------
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  Debenture  at  the principal office of the
Borrower.

     (B)     SURRENDER  OF  DEBENTURE UPON CONVERSION.  Notwithstanding anything
             ----------------------------------------
to  the  contrary set forth herein, upon partial conversion of this Debenture in
accordance  with  the  terms  hereof,  the Holder shall not (unless requested in
writing  by  the Borrower) be required to physically surrender this Debenture to
the  Borrower  unless the entire unpaid principal amount of this Debenture 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 Debenture 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 Debenture is converted as
aforesaid,  the  Holder  may not transfer this Debenture unless the Holder first
physically  surrenders  this  Debenture  to the Borrower, whereupon the Borrower
will forthwith issue and deliver upon the order of the Holder a new Debenture 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  Debenture.  The  Holder  and any
assignee, by acceptance of this Debenture, acknowledge and agree that, by reason
of  the  provisions of this paragraph, following conversion of a portion of this
Debenture,  the  unpaid  and  unconverted  principal  amount  of  this Debenture
represented  by  this  Debenture  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  Debenture 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 Debenture) (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 Debenture shall not bear any
restrictive  legend).

     (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  Debenture  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 Debenture 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 Debenture 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 Debenture, in which
event  interest  shall  accrue  thereon  in  accordance  with  the terms of this
Debenture  and such additional principal amount shall be convertible into Common
Stock  in  accordance  with  the  terms  of  this  Debenture.

     1.5     CONCERNING  THE  SHARES.  The  shares of Common Stock issuable upon
             -----------------------
conversion  of  this  Debenture  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 Debenture 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
Debenture  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:

"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
Debenture (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 Debenture, 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 Debenture 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.

     (B)     ADJUSTMENT  DUE  TO MERGER, CONSOLIDATION, ETC.     If, at any time
             -----------------------------------------------
when  this Debenture is issued and outstanding and prior to conversion of all of
the  Debentures,  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 Debenture
shall  thereafter  have  the right to receive upon conversion of this Debenture,
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  Debenture  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 Debenture
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 Debenture) 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
stockholders  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  Debenture) 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
Debenture  shall  be  entitled,  upon any conversion of this Debenture 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 Debentures
        -----------------------------------
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,
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.

     (E)     PURCHASE RIGHTS.     If, at any time when any Debentures 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  Debenture  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 Debenture (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  Debenture.

     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 Debenture and the other Debentures
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,  as  of the Issue Date shall be
3,898,315  shares  (19.99%  of  the total shares outstanding on the Issue Date),
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 Debenture, and
in  full  satisfaction  of  the Borrower's obligations under this Debenture, 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
          -----       ---
Debenture  immediately  following  the Maximum Conversion Date, plus (b) accrued
                                                                ----
and  unpaid  interest  on  the  unpaid principal amount of this Debenture 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  Debenture  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  Debentures,  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  Debenture  and the other Debentures issued pursuant to the
Purchase  Agreement plus (y) the aggregate number of shares of Common Stock that
                    ----
remain  issuable  upon  conversion  of  this  Debenture and the other Debentures
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 Stockholder 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, "STOCKHOLDER APPROVAL"
means  approval by the stockholders 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 Debentures but for the Maximum Share Amount.

     1.8     STATUS  AS  STOCKHOLDER.  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 Debenture 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  Debenture.  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  Debenture  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 Debenture with
respect  to  such unconverted portions of this Debenture and the Borrower shall,
as  soon  as practicable, return such unconverted Debenture to the Holder or, if
the  Debenture has not been surrendered, adjust its records to reflect that such
portion  of  this  Debenture  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  Debenture.


                         ARTICLE II.  CERTAIN COVENANTS

     2.1     DISTRIBUTIONS ON CAPITAL STOCK.  So long as the Borrower shall have
             ------------------------------
any obligation under this Debenture, 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.

     2.2     RESTRICTION  ON  STOCK  REPURCHASES.  So long as the Borrower shall
             -----------------------------------
have  any  obligation  under  this Debenture, 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  Debenture,  the  Borrower  shall  not, without the Holder's written
consent,  create,  incur,  assume  or suffer to exist any liability for borrowed
money, 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  Debenture.

     2.4     SALE  OF ASSETS.  So long as the Borrower shall have any obligation
             ---------------
under  this  Debenture,  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  Debenture, 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  Debenture, the Borrower shall not, without the Holder's
written  consent,  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:

     3.1     FAILURE  TO  PAY  PRINCIPAL OR INTEREST.  The Borrower fails to pay
             ---------------------------------------
the  principal hereof or interest thereon when due on this Debenture, 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 or Investment Options 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 Debenture
(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
Debenture  as  and  when  required  by this Debenture 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 Debenture as and when required by this Debenture 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 forty-five (45) days
following  the  Filing Date (as defined in the Registration Rights Agreement) or
obtain  effectiveness  with  the  Securities  and  Exchange  Commission  of  the
Registration Statement within one hundred twenty (120) days following the Filing
Date  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  thirty  (30)
consecutive  days  or  sixty  (60)  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  Debenture,  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
Debenture,  the  Purchase  Agreement  or  the  Registration  Rights  Agreement;

                                    ----
(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

Holder  shall  have  the  right  at any time, so long as the Borrower remains 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.

             ----------
amended  by an instrument in writing signed by the Borrower and the Holder.  The
term  "Debenture" and all reference thereto, as used throughout this instrument,
shall  mean  this  instrument  (and  the other Debentures 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  Debenture  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 Debenture must be an
"accredited  investor"  (as  defined  in  Rule  501(a)  of  the  1933  Act).
Notwithstanding  anything  in this Debenture to the contrary, this Debenture 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
             --------------------
Debenture,  the  Borrower  shall  pay  the  Holder  hereof  costs of collection,
including  reasonable  attorneys'  fees.

     4.6     GOVERNING  LAW.  THIS  DEBENTURE 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
EXCLUSIVE  JURISDICTION OF THE UNITED STATES FEDERAL COURTS LOCATED IN NEW YORK,
NEW  YORK  WITH  RESPECT  TO  ANY  DISPUTE  ARISING  UNDER  THIS  DEBENTURE, THE
AGREEMENTS  ENTERED INTO IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY. BOTH PARTIES IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT
FORUM TO THE MAINTENANCE OF SUCH SUIT OR PROCEEDING.  BOTH PARTIES FURTHER AGREE
THAT  SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED
IN EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR
PROCEEDING.  NOTHING  HEREIN  SHALL AFFECT EITHER PARTY'S RIGHT TO SERVE PROCESS
IN  ANY  OTHER  MANNER  PERMITTED  BY  LAW.  BOTH  PARTIES  AGREE  THAT  A FINAL
NON-APPEALABLE  JUDGMENT  IN ANY SUCH SUIT OR PROCEEDING SHALL BE CONCLUSIVE AND
MAY  BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON SUCH JUDGMENT OR IN ANY OTHER
LAWFUL  MANNER.  THE  PARTY  WHICH DOES NOT PREVAIL IN ANY DISPUTE ARISING UNDER
THIS  DEBENTURE  SHALL  BE  RESPONSIBLE  FOR  ALL  FEES  AND EXPENSES, INCLUDING
ATTORNEYS'  FEES,  INCURRED  BY  THE  PREVAILING  PARTY  IN CONNECTION WITH SUCH
DISPUTE.

     4.7     CERTAIN  AMOUNTS.  Whenever pursuant to this Debenture 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 Debenture 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
Debenture  and to earn a return from the sale of shares of Common Stock acquired
upon  conversion  of  this  Debenture at a price in excess of the price paid for
such  shares  pursuant  to  this  Debenture.  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  Debenture  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 Debentures based on the principal amount of such Debentures issued to
each  Holder.  Each  increase  to  the  Maximum Share Amount and Reserved Amount
shall  be  allocated  pro  rata  among  the  Holders  of Debentures based on the
principal  amount  of  such  Debentures  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  Debentures,  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  Debentures shall be allocated to the remaining Holders of Debentures,
pro  rata  based  on  the  principal amount of such Debentures 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 Debenture 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  Debenture,  the  Borrower  shall  promptly  issue  new  Debentures  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 Debenture, 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 Debenture shall have no rights as a Holder of Common Stock
unless and only to the extent that it converts this Debenture 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 Debenture will be inadequate and agrees, in the event of a breach or
threatened  breach by the Borrower of the provisions of this Debenture, 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 Debenture
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.

     5.1.     OPTIONAL  PREPAYMENT.  Notwithstanding  anything  to  the contrary
              --------------------
contained  in  this  Article V, for not more than thirty (30) days from the date
hereof,  so  long  as (i) no Event of Default or Trading Market Prepayment Event
shall  have  occurred  and be continuing, and (ii) the Borrower has a sufficient
number  of  authorized  shares  of  Common Stock reserved for issuance upon full
conversion  of  the  Debentures,  then  at  any  time  after the Issue Date, the
Borrower  shall  have  the  right, exercisable on not less than ten (10) Trading
Days prior written notice to the Holders of the Debentures (which notice may not
be  sent  to  the  Holders  of the Debentures until the Borrower is permitted to
prepay  the  Debentures  pursuant  to  this  Section  5.1), to prepay all of the
outstanding  Debentures  in  accordance  with  this  Section 5.1.  Any notice of
prepayment  hereunder  (an  "OPTIONAL  PREPAYMENT")  shall  be  delivered to the
Holders  of  the Debentures 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 Debentures 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  Debentures,  the Borrower shall make payment to the
holders  of  an  amount in cash (the "OPTIONAL PREPAYMENT AMOUNT") equal to 130%
multiplied  by  the  sum  of  (w)  the then outstanding principal amount of this
Debenture plus (x) accrued and unpaid interest on the unpaid principal amount of
          ----
this  Debenture  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 Debenture 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  Debentures  in  accordance  with  Article I and any portion of
Debentures 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 Debentures 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 Debentures within two (2)
business days following the Optional Prepayment Date, the Borrower shall forever
forfeit  its  right  to  redeem  the  Debentures  pursuant  to this Section 5.1.
