         This Debenture is subject to the following additional provisions:

         1. The Debentures will initially be issued in denominations determined

of the original purchaser hereof and may be transferred or exchanged only in
compliance with the Securities Act of 1933, as amended (the "Act"), and other
applicable state and foreign securities laws and the terms of the Securities
Purchase Agreement. In the event of any proposed transfer of this Debenture, the

other applicable state and foreign securities laws and the terms of the
Securities Purchase Agreement. Prior to due presentment for transfer of this

converted after the Maturity Date), the Holder of this Debenture is entitled, at
its option, subject to the following provisions of this Section 4, to convert
this Debenture at any time into shares of Common Stock, $0.001 par value
("Common Stock"), of the Company at the Conversion Price (as defined below). Any
such conversion is referred to as a "Voluntary Conversion." The minimum

         reporting the relevant information regarding the Common Stock, a

         "Lowest Fixed Conversion Price" means the lowest New Transaction Price

paragraph. The Notice of Conversion shall be executed by the Holder of this
Debenture and shall evidence such Holder's intention to convert this Debenture
or a specified portion hereof in the form annexed hereto as Exhibit A. Delivery
of the Notice of Conversion shall be accepted by the Company by hand, mail or

be changed by notice given to the Holder in the manner provided in the
Securities Purchase Agreement).

                  C. Notwithstanding any other provision hereof or of any of the
other Transaction Agreements, in no event (except (i) as specifically provided
herein as an exception to this provision, or (ii) while there is outstanding a
tender offer for any or all of the shares of the Company's Common Stock) shall
the Holder be entitled to convert any portion of this Debenture, or shall the
Company have the obligation to convert such Debenture (and the Company shall not
have the right to pay interest hereon in shares of Common Stock) to the extent
that, after such conversion or issuance of stock in payment of interest, 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 other convertible securities or of the unexercised portion of
warrants or other rights to purchase Common Stock), and (2) the number of shares
of Common Stock issuable upon the conversion of the Debentures 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 4.99% of the
outstanding shares of Common Stock (after taking into account the shares to be
issued to the Holder upon such conversion). 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, except as otherwise provided in clause (1) of such sentence. The
Holder, by its acceptance of this Debenture, further agrees that if the Holder
transfers or assigns any of the Debentures to a party who or which would not be
considered such an affiliate, such assignment shall be made subject to the
transferee's or assignee's specific agreement to be bound by the provisions of
this Section 4(C) as if such transferee or assignee were the original Holder
hereof. Nothing herein shall preclude the Holder from disposing of a sufficient
number of other shares of Common Stock

                                       4
<PAGE>

beneficially owned by the Holder so as to thereafter permit the continued
conversion of this Debenture.

                  D. (i) Subject to the terms of Section 4(C) and to the other
terms of this Section 4(D), interest on the principal amount of this Debenture
converted pursuant to a Notice of Conversion shall be due and payable, at the
option of the Company, in cash or, subject to the conditions of the next
sentence, in shares of Common Stock on the Interest Payment Date. Anything
herein to the contrary notwithstanding, the Company may elect to pay interest in
shares of Common Stock if, but only if, the shares of Common Stock issuable to
the Holder as such payment are covered by an effective Registration Statement.

                           (ii) If the interest payable in connection with a
Voluntary Conversion is to be paid in cash, the Company shall make such payment
within three (3) Trading Days after the Interest Payment Date. If the interest
is not paid by such third Trading Day, the interest must be paid in Common Stock
in accordance with the provisions of this Section 4(D), unless the Holder
consents otherwise in each specific instance.

                           (iii) Additional provisions regarding the payment of
interest on the principal amount of this Debenture are set forth in the
following provisions of this Section 4.

                           (iv) If interest is to be paid in Common Stock
(whether at the election of the Company or as required hereunder), the number of
shares of Common Stock to be received shall be determined by dividing the dollar
amount of the interest by the relevant Conversion Price in effect on the
relevant Interest Payment Date.

                           (v) If not paid in full on an Interest Payment Date,
interest shall be fully cumulative and shall accrue on a daily basis, based on a
365-day year, monthly or until paid, whichever is earlier.

                  E. Reference is made to the provisions of Section 4(g) of the
Securities Purchase Agreement, the terms of which are incorporated herein by
reference. The Conversion Price and other provisions of this Debenture shall be
adjusted as provided in the applicable provisions of said Section 4(g) of the
Securities Purchase Agreement.

                  F. (i) Anything in the other provisions of this Debenture or
any of the other Transaction Agreements to the contrary notwithstanding, the
Company shall have the right, in its discretion, to prepay the outstanding
principal of this Debenture, together with all accrued interest thereon, in
whole or in part, on the terms and conditions provided in this Section 4(F). If
the Company elects to make such a prepayment, the Company shall give the Holder
a written notice (the "Voluntary Prepayment Notice") of its election to prepay
all or a portion of then outstanding Debenture. The prepayment amount shall be
equal to one hundred twenty percent (120%) of the sum of (x) the principal of
this Debenture being prepaid, plus (y) accrued interest

                                       5
<PAGE>

thereon through the Voluntary Prepayment Date. Additional terms regarding this
prepayment right are provided below.

                           (ii) The Company may give a Voluntary Prepayment
Notice and make the prepayment only if, (x) on the date on which the Voluntary
Prepayment Notice is given and (y) on every Trading Day thereafter through and
including the Voluntary Prepayment Date,

         (x) there is an effective Registration Statement covering the resale of
         the shares issuable on conversion of this Debenture, and

         (y) there is no Event of Default hereunder or any event which, with the
         giving of notice or the passage of time (that is, without regard to any
         grace or cure periods), could be declared an Event of Default
         hereunder, and

         (z) the Common Stock of the Company, including any Conversion Shares to
         be issued on conversion of the Debenture during the Prepayment
         Conversion Period, are eligible for trading on an Acceptable Trading
         Market.

                           (iii) The Voluntary Prepayment Notice shall specify
(x) the principal amount of the Debenture being prepaid by the Company (the
"Voluntary Principal Prepayment Amount"), (y) the date (the "Voluntary
Prepayment Date"), which shall be not less than twenty (20) and not more than
forty (40) Trading Days after the Voluntary Prepayment Notice is received by the
Holder, on which such prepayment will be made, and (z) identify the bank (the
"Prepayment Bank") where the Voluntary Prepayment Funds (as defined below) have
been deposited. The Voluntary Prepayment Notice shall be accompanied by the
Prepayment Bank's confirmation to the Holder that funds (the "Voluntary
Prepayment Funds") equal to the Voluntary Prepayment Amount have been deposited
with the Prepayment Bank and instructions for the method by which the Holder can
provide instructions to the Prepayment Bank to make payment of the Voluntary
Prepayment Funds to the Holder (such payment to made by check or wire, as
specified by the Holder) on the Voluntary Prepayment Date.

                           (iv) Even after the issuance of a Voluntary
Prepayment Notice, the Holder may continue to convert this Debenture as provided
in the other provisions of this Debenture until this Debenture is paid in full.
If the Holder converts any portion of this Debenture after the date of the
Voluntary Prepayment Notice and prior to the payment of the Voluntary Prepayment
Funds to the Holder (the "Prepayment Conversion Period"), so that the then
outstanding principal of this Debenture is less than the Voluntary Prepayment
Principal Amount, the Company shall notify the Prepayment Bank of the then
outstanding principal of this Debenture; provided, however, if the Voluntary
Prepayment Principal Amount is less than the principal of the then Unconverted
Debenture, any such conversions made during the Prepayment Conversion Period
shall be deemed made in the following order of priority: (x) first, out of
principal of the Unconverted Debenture in excess of the Voluntary Prepayment
Principal Amount, and (y) then, out of the Voluntary Prepayment Principal
Amount. To the extent that any conversions made

                                       6
<PAGE>

during the Prepayment Conversion Period are deemed made out of the Voluntary
Prepayment Principal Amount, the Voluntary Prepayment Funds will then be
adjusted to and be deemed to be equal such outstanding principal plus all
accrued but unpaid interest thereon through the Voluntary Prepayment Date.

                           (v) If the Voluntary Prepayment Funds are not timely
paid or made available to the Holder, the Holder will have the option,
exercisable at any time prior to the actual payment of the Voluntary Prepayment
Funds (together with any additional interest accruing on the Prepayment
Principal Amount after the Prepayment Date) to effect either or both of the
following actions: (x) cancellation, ab initio, of the prepayment contemplated
by the Voluntary Prepayment Notice and (y) cancellation of the Company's
prepayment right under this Section 4(F).

                  G. (i) Anything in the other provisions of this Debenture or
any of the other Transaction Agreements to the contrary notwithstanding, the
Company shall have the right, on the terms and conditions provided in this
Section 4(G), to require the Holder to convert all or a specified portion of the
principal of this Debenture, together with all accrued interest thereon, on the
Mandatory Conversion Date (as defined below). On the Mandatory Conversion Date,
without further action by the Holder, the outstanding principal and accrued but
unpaid interest on this Debenture shall be deemed converted into Common Stock
(x) with respect to such principal, at the Conversion Price in effect on such
Mandatory Conversion Date, and (y) with respect to the interest at the
applicable rate contemplated by the provisions of Section 4(D)(iii) hereof on
such Mandatory Conversion Date. Any conversion contemplated by this Section 4(G)
shall be subject to the following terms and conditions of this Section 4(G), to
the extent relevant.

                           (ii) Subject to the provisions of subparagraph (iii)
below, if the Sale Price (as defined below) for the Common Stock is more than
the Target Price (as defined below) for each of fifteen (15) ) consecutive
Trading Days (the fifteenth of such consecutive Trading Days, the "Target
Trading Day"), the Company will have the right, in its discretion, to give the
Holder a written notice (a "Mandatory Conversion Notice") within five (5)
Trading Days after the Target Trading Day. The Mandatory Conversion Notice shall
state that the date specified in such notice (the "Mandatory Conversion Date"),
which date shall not be no earlier than twenty (20) Trading Days and no later
than sixty (60) Trading Days after the Target Trading Day, shall be deemed a
Mandatory Conversion Date.

                           (iii) Anything herein to the contrary
notwithstanding, the Company may give a Mandatory Conversion Notice and make the
conversions contemplated thereby only if, (x) on the date on which the Mandatory
Conversion Notice is given and (y) on every Trading Day thereafter through and
including the Mandatory Conversion Date,

         (x) there is an effective Registration Statement covering the resale of
         the shares issuable on conversion of this Debenture, and

                                       7
<PAGE>

         (y) there is no Event of Default hereunder or any event which, with the
         giving of notice or the passage of time (that is, without regard to any
         grace or cure periods), could be declared an Event of Default
         hereunder, and

         (z) the Common Stock of the Company, including the Conversion Shares to
         be issued on the Mandatory Conversion Date, are eligible for trading on
         an Acceptable Trading Market.

                           (iv) The term "Sale Price" means the 4:00 P.M.
closing sale price of the Common Stock on the Principal Trading Market on the
relevant Trading Day(s), as reported by the Reporting Service for the relevant
date. The term "Target Price" means $0.60 (which amount is subject to adjustment
to the same extent that the Fixed Conversion Price is adjusted other than
pursuant to Section 4(g) of the Agreement).

                           (v) If the Company properly and timely gives a
Mandatory Conversion Notice and all of the conditions referred in subparagraph
(iii) above are satisfied, the conversion contemplated by the Mandatory
Conversion Notice will be effected, subject to the provisions of subparagraph
(vi) below, on the Mandatory Conversion Date. If any of such conditions is not
true, the Mandatory Conversion Notice shall be deemed canceled ab initio.

                           (vi) The provisions of Section 4(C) shall apply on
the Mandatory Conversion Date. If, as a result of such provisions, the entire
portion of the Debenture provided for in the Mandatory Conversion Notice is not
converted on the Mandatory Conversion Date, the Company, without further notice
to the Holder, shall be deemed to have timely given one or more Mandatory
Conversion Notices for the balance of such portion providing for successive
Mandatory Conversion Dates, each of which deferred date is ten (10) Trading Days
after the immediately preceding Mandatory Conversion Date, until such portion of
this Debenture is fully converted or paid in full (or some combination thereof).

                           (vii) Prior to a Mandatory Conversion Date, including
after receiving a Mandatory Conversion Notice, the Holder shall continue to have
the right to convert any outstanding portion of this Debenture in accordance
with its terms until it is fully converted. Any such conversion shall be applied
against the mandatory conversion contemplated by the Mandatory Conversion
Notice.

                           (viii) If, as of the Mandatory Conversion Date, the
Company timely pays in full any accrued interest payable with respect to the
portion of the Debenture contemplated by the Mandatory Conversion Notice and
issues all shares then converted in accordance with, and subject to the other
provisions of this Section 4(G), then interest shall cease to accrue on any
remaining Unconverted Debenture to the extent included in the Mandatory
Conversion Notice. If such payment is not made timely or is not made in full,
interest shall continue to accrue until the earliest date after the initial
Mandatory Conversion Date on which all accrued interest through the date of
payment has in fact been paid, but cease to accrue thereafter. If the

                                       8
<PAGE>

Mandatory Conversion Notice does not contemplate that the entire outstanding
Debenture is to be converted on the Mandatory Conversion Date, then Interest
shall continue to accrue and be payable, without regard to the provisions of
this Section 4(G) with respect to any portion of the Debenture not so included
in the Mandatory Conversion Notice.

                  H. (i) Anything herein to the contrary notwithstanding, the
Company shall make payments in reduction of the obligations represented by this
Debenture in accordance with the terms of this Section 4(H).

                           (ii) Commencing on the first Trading Day of the
calendar month following the date on which the third monthly anniversary of the
Issue Date occurs, and on the first Trading Day of each subsequent calendar
month (each such date, a "Required Prepayment Date"), the Company shall pay to
the Holder an amount (the "Required Principal Payment") equal to four and 77/100
percent (4.77%) of the original principal of this Debenture but not more than
the then outstanding principal of this Debenture, together with accrued but
unpaid interest thereon (the "Required Interest Payment"). With respect to each
Required Prepayment Date, the relevant Required Principal Payment and the
relevant Required Interest Payment are referred to collectively as the "Required
Payment."

                           (iii) For each Required Prepayment Date which is
prior to the Effective Date, the Required Payment shall be made in cash. If less
than the full amount is paid, the amount actually paid shall be applied in the
following order of priority (x) first, to the Required Interest Payment; and (y)
then to principal of the Debenture. The failure to pay such full amount,
however, may result in an Event of Default.

                           (iv) For each Required Prepayment Date which is on or
after the Effective Date, the Company may, subject to the following provisions
of this Section 4(H), elect to make the Required Payment in cash or in shares of
Common Stock. Unless the Company notifies the Holder at least thirty (30) Days
in advance of the relevant Required Prepayment Date that it is electing to pay
the Required Payment in cash, the Company will be required to make such payment
in stock (subject to the following provisions of this Section 4(H)) on the
Required Payment Date. Notwithstanding the foregoing, the Company may only pay
the Required Payment in shares if the Registration Statement covering the
Conversion Shares to be issued in such payment is effective on the Payment Date
and on the date the Conversion Shares are delivered to the Holder.

                           (v) If, with respect to any Required Prepayment Date
on or after the Effective Date, the Company elects or is required to pay the
Required Payment in cash, the amount of such payment shall be equal to the sum
of (i) one hundred ten percent (110%) of the Required Principal Payment and (ii)
one hundred percent (100%) of the Required Interest Payment. If less than the
full amount is paid, the amount actually paid shall be applied in the following
order of priority (x) first, to the Required Interest Payment; (y) then, to the
extent of ten percent (10%) of the amount of the Required Principal Payment, to
a prepayment fee; and (z)

                                       9
<PAGE>

then to principal of the Debenture. The failure to pay such full amount,
however, may result in an Event of Default. If the entire amount is paid, the
outstanding principal of the Debenture shall be reduced by the amount of the
Required Principal Payment.

                           (vi) If the Required Payment is made in stock, as
provided herein, the Company shall issue shares to the Holder equal to the
Required Payment divided by the Prepayment Conversion Price.

                           (vii) The provisions of Section 4(C) shall apply on
each Required Prepayment Date. If, as a result of such provisions, the entire
portion of the Required Payment is not converted on the relevant Required
Prepayment Date, then there shall be one or more successive deferred Required
Prepayment Dates, each of which deferred date is five (5) Trading Days after the
immediately preceding Required Prepayment Date, until the Required Payment is
fully converted or paid in full (or some combination thereof).

                           (viii) The provisions of this Section 4(H)
notwithstanding, the Holder shall continue to have the right to convert any
outstanding portion of this Debenture in accordance with its terms until it is
fully converted or paid to the same extent as if this Section 4(H) were not
included in this Debenture.

                  I. (i) The following provisions apply to the issuances of
Common Stock in payment of the amounts due under this Debenture, whether as
principal or interest, as provided in the preceding provisions of this Section
4.

                           (ii) No fractional shares of Common Stock or scrip
representing fractions of shares will be issued on conversion, but the number of
shares issuable shall be rounded to the nearest whole share.

                           (iii) Each of the following dates shall constitute a
"Conversion Date":

         (x) For a Voluntary Conversion, the date on which the Holder faxes or
         otherwise delivers a Notice of Conversion to the Company so that it is
         received by the Company on or before such specified date shall be a
         "Conversion Date" for all purposes of this Debenture and the other
         Transaction Agreements.

         (y) For a Mandatory Conversion, the Mandatory Conversion Date shall be
         a "Conversion Date" with respect to the relevant shares for all
         purposes of this Debenture and the other Transaction Agreements,
         without the need for the Holder to submit a Notice of Conversion.

         (z) For a Required Payment which is made in stock, the Required Payment
         Date shall be deemed to be a "Conversion Date" with respect to the
         relevant shares for

                                       10
<PAGE>

         all purposes of this Debenture and the other Transaction Agreements,
         without the need for the Holder to submit a Notice of Conversion.

                           (iv) All shares issuable with respect to a Conversion
Date shall be deemed "Conversion Shares" for all purposes of this Debenture and
the other Transaction Agreements. Certificates representing the relevant
Conversion Shares ("Conversion Certificates") will be delivered to the Holder at
(x) with respect to a Voluntary Conversion, at the address specified in the
relevant Notice of Conversion, and (y) with respect to any conversion
contemplated hereby to the address separately identified by the Holder (and if
none, the Holder's the Holder's address for notices as contemplated by the
Securities Purchase Agreement, which address the Holder may change from time to
time in the manner provided therein), via express courier, by electronic
transfer or otherwise, within three (3) Trading Days (such third Trading Day,
the "Delivery Date") after the relevant Conversion Date. The Holder shall be
deemed to be the holder of the shares issuable to it in accordance with the
relevant provisions of this Section 4 on the Conversion Date.

                  J. Any payments under this Debenture shall be applied in the
following order of priority, First to interest, Second to any penalty amounts
and then to Principal in inverse order of maturity.

         5. A. Subject to the terms of the Securities Purchase Agreement, no
provision of this Debenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of, and interest on,
this Debenture at the time, place, and rate, and in the coin or currency or
where contemplated herein in shares of its Common Stock, as applicable, as
herein prescribed. This Debenture and all other Debentures now or hereafter
issued of similar terms are direct obligations of the Company.

                  B. Payment of this Debenture is secured pursuant to the terms
of the Security Interest Agreement, dated as of the date of the Agreement (the
"Security Interest Agreement") executed by the Company, as debtor, in favor of
the Buyer and the Other Buyers, as secured parties. The terms of the Security
Interest Agreement are incorporated herein by reference.

         6. No recourse shall be had for the payment of the principal of, or the
interest on, this Debenture, or for any claim based hereon, or otherwise in
respect hereof, against any incorporator, shareholder, officer or director, as
such, past, present or future, of the Company or any successor corporation,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issue hereof,
expressly waived and released.

         7. All payments contemplated hereby to be made "in cash" shall be made
in immediately available good funds of United States of America currency by wire
transfer to an account designated in writing by the Holder to the Company (which
account may be changed by notice similarly given). All payments of cash and each
delivery of shares of Common Stock

                                       11
<PAGE>

issuable to the Holder as contemplated hereby shall be made to the Holder at the
address last appearing on the Debenture Register of the Company as designated in
writing by the Holder from time to time; except that the Holder can designate,
by notice to the Company, a different delivery address for any one or more
specific payments or deliveries.

         8. If, for as long as this Debenture remains outstanding, the Company
enters into a merger (other than where the Company is the surviving entity) or
consolidation with another corporation or other entity or a sale or transfer of
all or substantially all of the assets of the Company to another person
(collectively, a "Sale"), the Company will require, in the agreements reflecting
such transaction, that the surviving entity expressly assume the obligations of
the Company hereunder. Notwithstanding the foregoing, if the Company enters into
a Sale and the holders of the Common Stock are entitled to receive stock,
securities or property in respect of or in exchange for Common Stock, then as a
condition of such Sale, the Company and any such successor, purchaser or
transferee will agree that the Debenture may thereafter be converted on the
terms and subject to the conditions set forth above into the kind and amount of
stock, securities or property receivable upon such merger, consolidation, sale
or transfer by a holder of the number of shares of Common Stock into which this
Debenture might have been converted immediately before such merger,
consolidation, sale or transfer, subject to adjustments which shall be as nearly
equivalent as may be practicable. In the event of any such proposed Sale, (i)
the Holder hereof shall have the right to convert by delivering a Notice of
Conversion to the Company within fifteen (15) days of receipt of notice of such
Sale from the Company, except that Section 4(C) shall not apply to such
conversion.

         9. If, at any time while any portion of this Debenture remains
outstanding, the Company spins off or otherwise divests itself of a part of its
business or operations or disposes of all or of a part of its assets in a
transaction (the "Spin Off") in which the Company, in addition to or in lieu of
any other compensation received and retained by the Company for such business,
operations or assets, causes securities of another entity (the "Spin Off
Securities") to be issued to security holders of the Company, the Company shall
cause (i) to be reserved Spin Off Securities equal to the number thereof which
would have been issued to the Holder had all of the Holder's Debentures
outstanding on the record date (the "Record Date") for determining the amount
and number of Spin Off Securities to be issued to security holders of the
Company (the "Outstanding Debentures") been converted as of the close of
business on the Trading Day immediately before the Record Date (the "Reserved
Spin Off Shares"), and (ii) to be issued to the Holder on the conversion of all
or any of the Outstanding Debentures, such amount of the Reserved Spin Off
Shares equal to (x) the Reserved Spin Off Shares multiplied by (y) a fraction,
of which (I) the numerator is the principal amount of the Outstanding Debentures
then being converted, and (II) the denominator is the principal amount of the
Outstanding Debentures.

         10. If, at any time while any portion of this Debenture remains
outstanding, the Company effectuates a stock split or reverse stock split of its
Common Stock or issues a dividend on its Common Stock consisting of shares of
Common Stock, the Conversion Price or the Lowest Fixed Conversion Price, if any,
and any other fixed amounts calculated as contemplated

                                       12
<PAGE>

hereby or by any of the other Transaction Agreements shall be equitably adjusted
to reflect such action. By way of illustration, and not in limitation, of the
foregoing, (i) if the Company effectuates a 2:1 split of its Common Stock,
thereafter, with respect to any conversion for which the Company issues shares
after the record date of such split, the Lowest Fixed Conversion Price, if any,
shall be deemed to be one-half of what it had been immediately prior to such
split; (ii) if the Company effectuates a 1:10 reverse split of its Common Stock,
thereafter, with respect to any conversion for which the Company issues shares
after the record date of such reverse split, the Lowest Fixed Conversion Price
shall be deemed to be ten times what it had been calculated to be immediately
prior to such split; and (iii) if the Company declares a stock dividend of one
share of Common Stock for every 10 shares outstanding, thereafter, with respect
to any conversion for which the Company issues shares after the record date of
such dividend, the Conversion Price (whether or not based on a Lowest Fixed
Conversion Price) shall be deemed to be such amount multiplied by a fraction, of
which the numerator is the number of shares (10 in the example) for which a
dividend share will be issued and the denominator is such number of shares plus
the dividend share(s) issuable or issued thereon (11 in the example).

         11. The Holder of the Debenture, by acceptance hereof, agrees that this
Debenture is being acquired for investment and that such Holder will not offer,
sell or otherwise dispose of this Debenture or the shares of Common Stock
issuable upon conversion thereof except under circumstances which will not
result in a violation of the Act or any applicable state Blue Sky or foreign
laws or similar laws relating to the sale of securities.

         12. This Debenture shall be governed by and construed in accordance
with the laws of the State of New York for contracts to be wholly performed in
such state and without giving effect to the principles thereof regarding the
conflict of laws. Each of the parties consents to the exclusive jurisdiction of
the federal courts whose districts encompass any part of the County of New York
or the state courts of the State of New York sitting in the County of New York
in connection with any dispute arising under this Debenture and hereby waives,
to the maximum extent permitted by law, any objection, including any objection
based on FORUM NON COVENIENS, to the bringing of any such proceeding in such
jurisdictions. To the extent determined by such court, the Company shall
reimburse the Holder for any reasonable legal fees and disbursements incurred by
the Holder in enforcement of or protection of any of its rights under any of
this Debenture.

         13. JURY TRIAL WAIVER. The Company and the Holder hereby waive a trial
by jury in any action, proceeding or counterclaim brought by either of the
Parties hereto against the other in respect of any matter arising out of or in
connection with this Debenture.

         14. (i) Prior to the Maturity Date, the following shall constitute an
"Event of Default":

             a. The Company shall default in the payment of principal or
                interest on this Debenture or any other Debenture in this Series
                or any other amount due

                                       13
<PAGE>

                hereunder or thereunder, and, (i) with respect to a payment of
                interest on a Scheduled Interest Payment Date, such default
                shall continue for a period of five (5) Trading Days after the
                Holder gives the Company's written notice thereof, and (ii) in
                all other instances, such default shall continue for a period of
                five (5) Trading Days; or

             b. Any of the representations or warranties made by the
                Company herein, in the Securities Purchase Agreement or any of
                the other Transaction Agreements or in any certificate or
                financial or other written statements heretofore or hereafter
                furnished by the Company in connection with the execution and
                delivery of this Debenture or the Securities Purchase Agreement
                shall be false or misleading in any material respect at the time
                made; or

             c. Subject to the terms of the Securities Purchase Agreement, the
                Company fails to authorize or to cause its Transfer Agent to
                issue shares of Common Stock upon exercise by the Holder of the
                conversion rights of the Holder in accordance with the terms of
                this Debenture (provided, however, that for purposes of this
                provision, such failure to cause the Transfer Agent to issue
                such shares shall not be deemed to occur until two (2) Trading
                Days after the Delivery Date), fails to transfer or to cause its
                Transfer Agent to transfer any certificate for shares of Common
                Stock issued to the Holder upon conversion of this Debenture and
                when required by this Debenture or any other Transaction
                Agreement, and such transfer is otherwise lawful, or fails to
                remove any restrictive legend on any certificate or fails to
                cause its Transfer Agent to remove such restricted legend, in
                each case where such removal is lawful, as and when required by
                this Debenture, or any other Transaction Agreement, and any such
                failure shall continue uncured for five (5)) Trading Days; or

             d. The Company shall fail to perform or observe, in any material
                respect, any other covenant, term, provision, condition,
                agreement or obligation of any Debenture in this series and such
                failure shall continue uncured for a period of thirty (30) days
                after the Company's receipt written notice from the Holder of
                such failure; or

             e. The Company shall fail to perform or observe, in any material
                respect, any covenant, term, provision, condition, agreement or
                obligation of the Company under any of the Transaction
                Agreements and such failure, if capable of being cured, shall
                continue uncured for a period of thirty (30) days after the
                Holder gives the Company written notice thereof (but if not
                capable of being cured, such thirty day period shall be deemed
                expired immediately upon the giving of such notice); or

                                       14
<PAGE>

             f. The Company shall (1) admit in writing its inability to pay its
                debts generally as they mature; (2) make an assignment for the
                benefit of creditors or commence proceedings for its
                dissolution; or (3) apply for or consent to the appointment of a
                trustee, liquidator or receiver for its or for a substantial
                part of its property or business; or

             g. A trustee, liquidator or receiver shall be appointed for the
                Company or for a substantial part of its property or business
                without its consent and shall not be discharged within sixty
                (60) days after such appointment; or

             h. Any governmental agency or any court of competent jurisdiction
                at the instance of any governmental agency shall assume custody
                or control of the whole or any substantial portion of the
                properties or assets of the Company and shall not be dismissed
                within sixty (60) days thereafter; or

             i. Any money judgment, writ or warrant of attachment, or similar
                process in excess of Seven Hundred Fifty Thousand ($750,000)
                Dollars in the aggregate shall be entered or filed against the
                Company or any of its properties or other assets and shall
                remain unpaid, unvacated, unbonded or unstayed for a period of
                sixty (60) days or in any event later than five (5) days prior
                to the date of any proposed sale thereunder; or

             j. Bankruptcy, reorganization, insolvency or liquidation
                proceedings or other proceedings for relief under any bankruptcy
                law or any law for the relief of debtors shall be instituted by
                or against the Company and, if instituted against the Company,
                shall not be dismissed within sixty (60) days after such
                institution or the Company shall by any action or answer approve
                of, consent to, or acquiesce in any such proceedings or admit
                the material allegations of, or default in answering a petition
                filed in any such proceeding; or

             k. The Company shall have its Common Stock suspended from trading
                on, or delisted from, the Principal Trading Market for in excess
                of ten (10) Trading Days.

             (ii) After the Maturity Date, the term "Event of Default"
shall mean:

             a. The Company shall default in the payment of principal or
                interest on this Debenture or any other amount due hereunder,
                and, in any such instance, the same shall continue for a period
                of five (5) Trading Days; or

                                       15
<PAGE>

             b. Subject to the terms of the Securities Purchase Agreement, the
                Company fails to authorize or to cause its Transfer Agent to
                issue shares of Common Stock upon exercise by the Holder of the
                conversion rights of the Holder in accordance with the terms of
                this Debenture (provided, however, that for purposes of this
                provision, such failure to cause the Transfer Agent to issue
                such shares shall not be deemed to occur until two (2) Trading
                Days after the Delivery Date), fails to transfer or to cause its
                Transfer Agent to transfer any certificate for shares of Common
                Stock issued to the Holder upon conversion of this Debenture and
                when required by this Debenture or any other Transaction
                Agreement, and such transfer is otherwise lawful, or fails to
                remove any restrictive legend on any certificate or fails to
                cause its Transfer Agent to remove such restricted legend, in
                each case where such removal is lawful, as and when required by
                this Debenture, or any other Transaction Agreement, and any such
                failure shall continue uncured for five (5) Trading Days.

          (iii) If an Event of Default shall have occurred and is
continuing, then,

         (x) unless and until such Event of Default shall have been cured or
         waived in writing by the Holder (which waiver shall not be deemed to be
         a waiver of any subsequent default), at the option of the Holder and in
         the Holder's sole discretion, but without further notice from the
         Holder, the unpaid amount of this Debenture, computed as of such date,
         will bear interest at the rate of eighteen percent (18%) or the highest
         rate allowed by law, whichever is lower, from the date of the Event of
         Default to until and including the date actually paid; and any partial
         payments shall be applied first to all accrued interest and then to
         principal; and

         (y) at any time thereafter, and in each and every such case, unless
         such Event of Default shall have been cured or waived in writing by the
         Holder (which waiver shall not be deemed to be a waiver of any
         subsequent default), at the option of the Holder and in the Holder's
         sole discretion, the Holder may elect to redeem all or part of the
         Unconverted Debenture (as defined below) on the terms provided in
         Section 15 hereof.

         15. A. The Company acknowledges that if there is an Event of Default,
the Holder may require the Company to immediately redeem all or any part of the
outstanding portion of this Debenture for an amount equal to the Redemption
Amount (as defined below).

             B. For purposes of this Debenture, the following terms shall
have the meanings indicated below:

                                       16
<PAGE>

         "Unconverted Debenture" means the principal amount of this Debenture
         which has not been converted as of the relevant date.

         "Redemption Payment Date" means the date on which the Company actually
         pays the Redemption Amount.

         "Redemption Amount" means the amount equal to:

                               V                           x                M
                        -----------------
                             CP

                  where:

                           "V" means  the  principal  of an  Unconverted
                  Debenture  plus any accrued but unpaid interest thereon;

                           "CP" means the Variable Conversion Price in effect on
                  the date (the "Redemption Notice Date") of the Redemption
                  Notice (as defined below); and

                           "M" means the highest closing price per share of the
                  Common Stock during the period beginning on the Redemption
                  Notice Date and ending on the Redemption Payment Date.

                  C. The Holder of an Unconverted Debenture may elect to redeem
a portion of such Unconverted Debenture without electing to redeem the balance
of the Unconverted Debenture. The Holder's option to redeem all or part of the
Unconverted Debenture shall be exercised by the Holder giving written notice of
the exercise of this provision by the Holder (a "Redemption Notice") at any time
after a relevant Event of Default has occurred. The Redemption Notice shall
specify (a) the date (the "Redemption Due Date") on which the Redemption Amount
shall be paid, which date shall be at least five (5) Trading Days after the date
(a "Redemption Notice Date") on which the Holder Redemption Notice is given, and
(b) the wire instructions for the account to which the Redemption Amount is to
be paid; provided, however, that the Company shall have the right to accelerate
the date of such payment.

                  D. If all of the Unconverted Debentures are being redeemed
pursuant to this Section 5, then, upon payment in full of the Redemption Amount
for all of the Unconverted Debentures in accordance with the provisions of this
Section 5, the Holder shall deliver the Debenture to the Company marked "paid in
full".

                  E. If the Redemption Amount is not timely paid by the Company,
the Holder may declare the Redemption Amount due under this Debenture
immediately due and payable, without presentment, demand, protest or notice of
any kinds, all of which are hereby expressly

                                       17
<PAGE>

waived, anything herein or in any
note or other instruments contained to the contrary notwithstanding, and the
Holder may immediately enforce any and all of the Holder's rights and remedies
provided herein or any other rights or remedies afforded by law, including, but
not necessarily limited to, the equitable remedy of specific performance and
injunctive relief.

         16. Nothing contained in this Debenture shall be construed as
conferring upon the Holder the right to vote or to receive dividends or to
consent or receive notice as a shareholder in respect of any meeting of
shareholders or any rights whatsoever as a shareholder of the Company, unless
and to the extent converted in accordance with the terms hereof.

         17. Any notice required or permitted hereunder shall be given in manner

         18. In the event for any reason, any payment by or act of the Company
or the Holder shall result in payment of interest which would exceed the limit
authorized by or be in violation of the law of the jurisdiction applicable to
this Debenture, then IPSO facto the obligation of the Company to pay interest or
perform such act or requirement shall be reduced to the limit authorized under
such law, so that in no event shall the Company be obligated to pay any such
interest, perform any such act or be bound by any requirement which would result
in the payment of interest in excess of the limit so authorized. In the event
any payment by or act of the Company shall result in the extraction of a rate of
interest in excess of a sum which is lawfully collectible as interest, then such
amount (to the extent of such excess not returned to the Company) shall, without
further agreement or notice between or by the Company or the Holder, be deemed
applied to the payment of principal, if any, hereunder immediately upon receipt
of such excess funds by the Holder, with the same force and effect as though the
Company had specifically designated such sums to be so applied to principal and
the Holder had agreed to accept such sums as an interest-free prepayment of this
Debenture. If any part of such excess remains after the principal has been paid
in full, whether by the provisions of the preceding sentences of this Section or
otherwise, such excess shall be deemed to be an interest-free loan from the
Company to the Holder, which loan shall be payable immediately upon demand by
the Company. The provisions of this Section shall control every other provision
of this Debenture.

         IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by an officer thereunto duly authorized.

         Newton, Massachusetts 02458
         Attn: President

FROM: _________________________________________________________ ("Holder")

DATE: _______________________________________________ (the "Conversion Date")

RE:      Conversion of $_________________ principal amount (the "Converted
         Debenture") of the 8% Senior Secured Convertible Debenture Series
         06-02-___ Due __________, 2008 (the "Debenture") of AMBIENT CORPORATION
         (the "Company") into ______________________ shares (the "Conversion
         Shares") of Common Stock (defined below)

         The captioned Holder hereby gives notice to the Company, pursuant to
the Debenture of AMBIENT CORPORATION that the Holder elects to convert the
Converted Debenture into fully paid and non-assessable shares of Common Stock,
$0.001 par value (the "Common Stock"), of the Company as of the Conversion Date
specified above. Said conversion shall be based on the following Conversion
Price (CHECK AND FILL IN ONE):

[ ]      $________________, representing the Fixed Conversion Price (as defined
         in the Debenture)
               [ ] adjusted in accordance with the provisions of the Debenture

[ ]            $________________, representing the Lowest Fixed Conversion Price
               [ ] adjusted in accordance with the provisions of the Debenture

[ ]            $________________, representing the Prepayment Conversion Price

<PAGE>

Based on this Conversion Price, the number of Conversion Shares indicated above
should be issued in the following name(s):

           -------------------------------            -----------------

         It is the intention of the Holder to comply with the provisions of
Section 4(C) of the Debenture regarding certain limits on the Holder's right to
convert thereunder. Based on the analysis on the attached Worksheet Schedule,
the Holder believe this conversion complies with the provisions of said Section
4(C). Nonetheless, to the extent that, pursuant to the conversion effected
hereby, the Holder would have more shares than permitted under said Section,
this notice should be amended and revised, ab initio, to refer to the conversion
which would result in the issuance of shares consistent with such provision. Any
conversion above such amount is hereby deemed void and revoked.

         As contemplated by the Debenture, this Notice of Conversion is being
sent by facsimile to the telecopier number and officer indicated above.

         If this Notice of Conversion represents the full conversion of the
outstanding balance of the Converted Debenture, the Holder either (1) has
previously surrendered the Converted Debenture to the Company or (2) will
surrender (or cause to be surrendered) the Converted Debenture to the Company at
the address indicated above by express courier within five (5) Trading Days
after delivery or facsimile transmission of this Notice of Conversion.

         The certificates representing the Conversion Shares should be
transmitted by the Company to the Holder

         [ ]      via express courier, or

         [ ]      by electronic transfer

within the time contemplated by the Debenture after receipt of this Notice of
Conversion (by facsimile transmission or otherwise) to:

         As contemplated by the Debenture, the Company should also pay all
accrued but unpaid interest on the Converted Debenture to the Holder.

                           --If the Company elects to pay such interest in
                  Common Stock, as contemplated by and subject to the provisions
                  of the Debenture,(3) such shares should be issued in the name
                  of the Holder and delivered in the same manner as, and
                  together with, the Conversion Shares.

                           --If the Company elects or is required to pay the

thereof and not with a view to or for sale in connection with any distribution

defined in Rule 501 of the General Rules and Regulations under the 1933 Act,
(ii) experienced in making investments of the kind described in this Agreement
and the other Transaction Agreements, (iii) able, by reason of the business and
financial experience of its officers (if an entity) and professional advisors
(who are not affiliated with or compensated in any way by the Company or any of
its Affiliates or selling agents), to protect its own interests in connection
with the transactions described in this Agreement and the other Transaction
Agreements, and to evaluate the merits and risks of an investment in the
Securities, and (iv) able to afford the entire loss of its investment in the
Securities.

                  C. All subsequent offers and sales of the Securities by the
Buyer shall be made pursuant to registration of the relevant Securities under

                  D. The Buyer understands that the Securities are being offered
and sold to it in reliance on specific exemptions from the registration
requirements of the 1933 Act and state securities laws and that the Company is
relying upon the truth and accuracy of, and the Buyer's compliance with, the
representations, warranties, agreements, acknowledgments and understandings of
the Buyer set forth herein in order to determine the availability of such
exemptions and the eligibility of the Buyer to acquire the Securities.

                  E. The Buyer and its advisors, if any, have been furnished
with or have been given access to all materials relating to the business,
finances and operations of the Company and materials relating to the offer and
sale of the Purchased Securities which have been requested by the Buyer,
including those set forth in any annex attached hereto. The Buyer and its
advisors, if any, have been afforded the opportunity to ask questions of the
Company and its management and have received complete and satisfactory answers
to any such inquiries. Without limiting the generality of the foregoing, the
Buyer has also had the opportunity to obtain and to review the Company's SEC
Documents.

                  F. The Buyer understands that its investment in the Securities
involves a high degree of risk.

payment for and continued beneficial ownership, if any, of the Securities will
not violate any applicable securities or other laws of the Buyer's jurisdiction.

                  H. If the Buyer is an individual, then the Buyer resides in

has not relied on any statement or representation of any Person, including any
such statement or representation by the Company or the Placement Agent or any of
their respective controlling Persons, officers, directors, partners, agents and
employees or any of their respective attorneys, except as specifically set forth
herein. The Buyer agrees that none of (i) any Other Buyer, (ii) any controlling

Other Buyer or (iii) any of their respective attorneys shall be liable to the

and each of their respective controlling Persons, officers, directors, partners,
agents and employees and each of their respective attorneys is a third party
beneficiary of this provision.

                  J. The Buyer understands that no United States federal or
state agency or any other government or governmental agency has passed on or
made any recommendation or endorsement of the Securities.

                  K. This Agreement and each of the other Transaction
Agreements, and the transactions contemplated hereby and thereby, have been duly

validly existing and in good standing under the laws of the State of
Incorporation and has the requisite corporate power to own its properties and to
carry on its business as now being conducted. The Company is duly qualified as a
foreign corporation to do business and is in good standing in each jurisdiction
where the nature of the business conducted or property owned by it makes such
qualification necessary, other than those jurisdictions in which the failure to
so qualify would not have or result in a Material Adverse Effect. The Company

action on the part of the Company, and, when issued on conversion of, or in

instrumentality or any other person, wherein an unfavorable decision, ruling or
finding would have a Material Adverse Effect or which would adversely affect the
validity or enforceability of, or the authority or ability of the Company to
perform its obligations under, any of the Transaction Agreements. The Company is
not aware of any valid basis for any such claim that (either individually or in
the aggregate with all other such events and circumstances) could reasonably be

disclosed in the Transaction Agreements or the Company's SEC Documents or those
incurred in the ordinary course of the Company's business since the Last Audited
Date, or which individually or in the aggregate, do not or would not have a
Material Adverse Effect. No event or circumstance has occurred or exists with

(financial or otherwise), or results of operations, which, under applicable law,
rule or regulation, requires public disclosure or announcement prior to the date
hereof by the Company but which has not been so publicly announced or disclosed.
There are no proposals currently under consideration or currently anticipated to
be under consideration by the Board of Directors or the executive officers of
the Company which proposal would (x) change the articles or certificate of
incorporation or other charter document or by-laws of the Company, each as
currently in effect, with or without stockholder approval, which change would
reduce or otherwise adversely affect the rights and powers of the stockholders
of the Common Stock or (y) materially or substantially change the business,
assets or capital of the Company, including its interests in subsidiaries.

Affiliates nor any Person acting on its or their behalf has, directly or

security or solicited any offers to buy any security under circumstances that
would eliminate the availability of the exemption from registration under
Regulation D in connection with the offer and sale of the Securities as
contemplated hereby.

                  O. DILUTION. Each of the Company and its executive officers
and directors is aware that the number of shares issuable on conversion of the
Debentures, upon exercise of the Warrants or pursuant to the other terms of the

exercise of the Warrants or the Payment Shares as provided in the Registration

of the Company, and the Company will honor such obligations, including honoring
every Notice of Conversion (as contemplated by the Debentures), every Notice of
Exercise (as contemplated by the Warrants), and every demand for Payment Shares
(as contemplated by the Registration Rights Agreement), unless the Company is
subject to an injunction (which injunction was not sought by the Company)
prohibiting the Company from doing so.

                  P. FEES TO BROKERS, PLACEMENT AGENTS AND OTHERS. The Company
has taken no action which would give rise to any claim by any Person for
brokerage commission, placement agent or finder's fees or similar payments by
Buyer relating to this Agreement or the transactions contemplated hereby.
Notwithstanding the foregoing, the Company acknowledges that it has agreed to
pay the Placement Agent's Compensation (as defined in the Joint Escrow
Instructions) to the Placement Agent in connection with the transactions
contemplated hereby. Except for such fees arising as a result of any agreement
or arrangement entered into by the Buyer without the knowledge of the Company (a
"Buyer's Fee"), Buyer shall have no obligation with respect to such fees or with
respect to any claims made by or on behalf of other Persons for fees of a type
contemplated in this paragraph that may be due in connection wit h the
transactions contemplated hereby. The Company shall indemnify and hold harmless
each of Buyer, its employees, officers, directors, agents, and partners, and
their respective Affiliates, from and against all claims, losses, damages, costs
(including the costs of preparation and attorney's fees) and expenses suffered
in respect of any such claimed or existing fees (other than a Buyer's Fee).

                  Q. DISCLOSURE. No event or circumstance has occurred or exists
with respect to the Company or its business, properties, prospects, operations
or financial conditions, which under applicable law, rule or regulation,
requires public disclosure or announcement by the Company.

                  R. CONFIRMATION. The Company confirms that all representations
and warranties of the Company contained herein shall survive the closing under
this Agreement by the Buyer for a period of three (3) years from the Closing
Date. The Company agrees that, if, to the knowledge of the Company, any events
occur or circumstances exist prior to the release of the Escrow Funds to the
Company which would make any of the Company's representations or warranties set
forth herein materially untrue or materially inaccurate as of such date, the
Company shall immediately notify the Buyer (directly or through the Placement
Agent ) and the Document Escrow Agent in writing prior to such date of such
fact, specifying which representation, warranty or covenant is affected and the
reasons therefor.

                  4. CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

                  A. TRANSFER RESTRICTIONS.

                  (i) The Buyer acknowledges that (1) the Securities have not
been and are not being registered under the provisions of the 1933 Act and,
except as provided in the Registration Rights Agreement or otherwise included in
an effective registration statement, the Shares have not been and are not being
registered under the 1933 Act, and may not be transferred unless (A)
subsequently registered thereunder or (B) the Buyer shall have delivered to the
Company an opinion of counsel, reasonably satisfactory in form, scope and
substance to the Company, to the effect that the Securities to be sold or
transferred may be sold or transferred pursuant to an exemption from such
registration; (2) any sale of the Securities made in reliance on Rule 144 may be
made only in accordance with the terms of said Rule and further, if said Rule is
not applicable, any resale of such Securities under circumstances in which the
seller, or the Person through whom the sale is made, may be deemed to be an
underwriter, as that term is used in the 1933 Act, may require compliance with
some other exemption under the 1933 Act or the rules and regulations of the SEC
thereunder; and (3) neither the Company nor any other Person is under any
obligation to register the Securities (other than pursuant to the Registration
Rights Agreement) under the 1933 Act or to comply with the terms and conditions
of any exemption thereunder.

<PAGE>

                  (ii) In addition to the foregoing, and not in lieu thereof,
the Buyer agrees that, without the express written consent of the Company in
each instance, it will not transfer any of the Purchased Securities to any
Person which is known to the Buyer to be in substantially the same business as
the Company or which is known to be a subsidiary or affiliate of such a Person.

                  B. RESTRICTIVE LEGEND. The Buyer acknowledges and agrees that,
until such time as the relevant Shares have been registered under the 1933 Act,
as contemplated by the Registration Rights Agreement, and may be sold in
accordance with an effective Registration Statement or otherwise in accordance
with another effective registration statement, or until such Shares can
otherwise be sold without restriction, whichever is earlier, the certificates
and other instruments representing any of the Securities shall bear a
restrictive legend in substantially the following form (and a stop-transfer
order may be placed against transfer of any such Securities):

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE
         SOLD OR OFFERED FOR SALE IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
         STATEMENT FOR THE SECURITIES OR AN OPINION OF COUNSEL OR OTHER EVIDENCE
         ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

                  C. FILINGS. The Company undertakes and agrees to make all
filings required to be made by it in connection with the sale of the Securities
to the Buyer under the 1933 Act, the 1934 Act or the securities laws and
regulations of any of the United States applicable to the Company or by the
rules and regulations of the Principal Trading Market, and, unless such filing
is publicly available on the SEC's EDGAR system (via the SEC's web site at no
additional charge), to provide a copy thereof to the Buyer promptly after such
filing. Reference is made to the Section titled "Publicity, Filings, Releases,
Etc." below.

                  D. REPORTING STATUS. So long as there remains outstanding
either Convertible Debentures in aggregate principal amount equal to 10% of the
Aggregate Purchase Price or Warrants to purchase the number of shares of Common
Stock equal to 10% of the Issue Date Conversion Shares and for at least twenty
(20) Trading Days thereafter, the Company shall file all reports required to be
filed with the SEC pursuant to Section 13 or 15(d) of the 1934 Act, shall take
all reasonable action under its control to ensure that adequate current public
information with respect to the Company, as required in accordance with Rule
144(c)(2) of the 1933 Act, is publicly available, and shall not terminate its
status as an issuer required to file reports under the 1934 Act even if the 1934
Act or the rules and regulations thereunder would permit such termination. The
Company will take all reasonable action under its control to maintain the
continued listing and quotation and trading of its Common Stock (including,
without limitation, all Registrable Securities) on the Principal Trading Market
or a listing on the NASDAQ Capital or National Markets or AMEX and, to the
extent applicable to it, will comply in all material respects with the Company's
reporting, filing and other obligations under the by-laws or rules of the
Principal Trading Market and/or the National Association of Securities Dealers,
Inc., as the case may be, applicable to it at least through the date which is
sixty (60) days after the later of the date on which (x) all of the Debentures
have been converted or have been paid in full or (y) all of the Warrants have
been exercised or have expired.

                  E. USE OF PROCEEDS. The Company will use the net proceeds
received hereunder (excluding amounts paid as contemplated by the Joint Escrow
Instructions) as provided in ANNEX IX attached hereto (the "Use of Proceeds").
The Use of Proceeds provides, among other things, that such net proceeds on the
Closing Date shall be used (i) first, for repayment of the promissory notes
identified in the Use of Proceeds (each, a "Specified Note") to the holders
thereof named therein (each, a "Specified Holder"); and (ii) then, for general
corporate purposes; provided however, the Company will not use such to pay fees
payable (x) to another broker or finder (other than the Placement Agent)
relating to the offer and sale of the Purchased Securities or (y) to any other
party relating to any financing transaction effected prior to the Closing Date.

                  F. WARRANTS.

<PAGE>

                  (i) The Company agrees to issue to the Buyer on the Closing
Date two (2) separate transferable warrants (each, a "Warrant" and,
collectively, the "Warrants"), designated as Class 2006-A ("Class A") and Class
2006-B ("Class B") Warrants, respectively.

                  (ii) Each Class A Warrant and each Class B Warrant shall be
for the purchase of a number of shares of Common Stock equal to fifty percent
(50%) of the Issue Date Conversion Shares, or a total of 100% of the Issue Date
Conversion Shares for all Warrants combined.

                  (iii) Each Warrant shall have an exercise price (each, an
"Exercise Price") as follows: (i) Class A - $0.20; and (ii) Class B - $0.25;
each such Exercise Price will be subject to adjustment as provided in the
Warrant.

                  (iv) Each of the Warrants shall be exercisable commencing on
the Commencement Date specified in the Warrants. Each of the Warrants shall
expire at the close of business on its expiration date, which dates are as
follows: (i) Class A - the date which is the last day of the calendar month in
which the third annual anniversary of the Effective Date occurs; and (ii) Class
B - the date which is the last day of the calendar month in which the fifth
annual anniversary of the Effective Date occurs.

                  (v) Each Warrant shall have cashless exercise rights as
provided in the Warrant. Except as specified above, each Warrant shall generally
be in the form annexed hereto as Annex V.

                  (vi) The Warrant Shares shall be subject to the provisions of
the Registration Rights Agreement.

                  G. CERTAIN AGREEMENTS.

                  (i) For purposes of this Agreement, the following terms shall
have meanings indicated:

         (A) "New Transaction Period" means the period commencing on the Closing
         Date and continuing through and including the Final Lock-up Date.

         (B) "Final Lock-up Date" means the date which is the earlier of (i) the
         date on which the aggregate principal amount of all outstanding
         Debentures is twenty-five percent (25%) or less of the Aggregate
         Purchase Price, or (ii) the date which is 540 days after the Effective
         Date, but not counting for such purposes the days, if any, during which
         sale of Registrable Securities was suspended after the Effective Date.

         (C) "New Transaction Price" means the Basic New Transaction Price (as
         defined below) except that if the New Transaction Exercise Price is
         lower than the Basic New Transaction Price, it means the New
         Transaction Exercise Price.

         (D) "Basic New Transaction Price" means, as may be applicable, on a per
         share basis, the lower of (1) the lowest fixed purchase price of any
         shares of the New Common Stock contemplated in the New Transaction, or
         (2) the lowest conversion price or put or call price which would be
         applicable under the terms of the New Transaction; in each such case,
         whether such purchase or conversion price or put or call price is
         stated or otherwise specified or is determined on the closing date of
         the New Transaction by the application of a formula set in the
         documents reflecting the New Transaction or could result from
         adjustments or revisions contemplated in the relevant agreements for
         the New Transaction and whenever such adjustment or revision would be
         applicable (and if no minimum purchase price, conversion price or put
         or call price, as the case may be, is set, it shall be assumed that
         such minimum purchase price or conversion price is $.01); and provided,
         further, that, if the securities issued in the New Transaction are

<PAGE>

         issued at a Face Value Discount (as defined below), the New Transaction
         Price shall be adjusted to reflect such discount.(3)

         (E) "Exercise Threshold Price" means the then applicable Exercise
         Price.

         (F) "New Transaction Exercise Price" means the lowest exercise price
         per share applicable to the warrants, option or similar instrument
         (howsoever denominated; collectively, "New Transaction Warrants")
         included in such New Transaction, whether such exercise price is stated
         or could result from adjustments or revisions contemplated in the
         relevant agreements for the New Transaction and whenever such exercise
         price would be applicable (and, if no minimum exercise price is set, it
         shall be assumed that such minimum exercise price is $.01).

         (G) "Alternative Warrant Percentage" means, with respect to the
         relevant New Transaction, (1) the number of shares which are eligible
         to be purchased under the New Transaction Warrants, divided by (2) the
         aggregate of the shares of New Common Stock issued or issuable in such
         transaction (excluding the shares issuable on exercise of the New
         Transaction Warrants).

         (H) "Current Warrant Percentage" means, as of immediately before the
         consummation of the relevant New Transaction, the higher of (1) one
         hundred percent (100%) or (2) the highest Alternative Warrant
         Percentage of any preceding New Transaction.

         (I) "Outstanding Warrant Shares" means, for the Warrants or for any
         previously issued Added Warrants, the then outstanding number of
         Warrant Shares which would then be issuable upon the exercise in full
         of such Warrants (without regard to any limitations which may then
         restrict the Holder's full exercise of such Warrant at any time) or
         such Added Warrants, if any, as in effect immediately prior to the
         relevant New Transaction.

         (J) "Original Warrant Shares" means, for the Warrants or for any
         previously issued Added Warrants, the original number of Warrant Shares
         issuable on exercise of such Warrants on the relevant Closing Date or
         as Added Warrants, as the case may be (in each case without regard to
         any limitations which may then restrict the Holder's full exercise of
         such Warrant at any time).

         (K) "Face Value Discount" means consideration less than, as the case
         may be, (x) the number of shares being issued multiplied by the stated
         purchase price, (y) the stated principal amount of a debenture, note or
         similar instrument or (z) the stated value of the shares of convertible
         stock.

                  (ii) The Company covenants and agrees that, if, during the New
Transaction Period, without the prior written consent of a Majority in Interest
of the Holders in each instance (which consent is in the sole discretion of the
Holders), the Company enters into a New Transaction, then

         (A) the New Transaction Price shall be deemed to be the "Lowest Fixed
         Conversion Price" for purposes of clause (y) of the definition of
         "Conversion Price" in the Debentures for all Unconverted Debentures;
         provided, however, if there was one or more previous New Transaction
         Prices, the Lowest Fixed Conversion Price shall be the lowest New
         Transaction Price(4) of all New Transactions; and

_____________________________
(3)By way of illustration, if convertible preferred shares having a stated value
of $1 million and a fixed conversion price of $0.05 were sold for a purchase
price of $800,000, the effective New Transaction Price would be $0.04.
(4)Any New Transaction Price shall be adjusted for subsequent events as
contemplated by the Debentures.

<PAGE>

         (B) if the New Transaction Exercise Price of any of the New Transaction
         Warrants is lower than the Exercise Threshold Price of the Warrants,
         then the Exercise Price of the then outstanding Warrants shall be
         adjusted to be equal to the New Transaction Exercise Price of such New
         Transaction Warrants; and

         (C) if the provisions applicable to the convertible preferred stock,
         convertible debenture or similar instrument (howsoever denominated), if
         any, of the New Transaction are more beneficial to the holder of such
         instrument than the corresponding terms applicable to the Debentures or
         in or to the Warrants, as the case may be, or if the terms which are
         beneficial to the Company in the relevant Transaction Agreements are
         not included in the corresponding instrument in the New Transaction,
         then, unless waived by the Majority in Interest of the Holders, the
         terms of the Transaction Agreements applying to the then outstanding
         Debentures or the Warrants or to the other Transaction Agreements, as
         the case may be, shall be modified to reflect similar terms (based, if
         relevant, on the Closing Date); provided, however, that nothing in this
         provision shall be read to mean that the Purchased Securities shall be
         changed to any other form of security;

         (D) if either (1) the Conversion Price is adjusted as contemplated by
         clause (A) above, and/or (2) the Alternative Warrant Percentage is
         greater than the Current Warrant Percentage (whether or not the
         Conversion Price has been adjusted as a result of the New Transaction),
         the Company shall issue to the Holder additional warrants ("Added
         Warrants") for the purchase of the number of shares equal to the
         excess, if any, of

                           (x) (I) the higher of (a) the Alternative Warrant
                  Percentage or (b) the Current Warrant Percentage, multiplied
                  by (II) (a) the Purchase Price, divided by (b) the Conversion
                  Price as determined on the Closing Date or on the closing date
                  of the New Transaction, whichever is lower, multiplied by
                  (III) a fraction, of which the numerator is the Outstanding
                  Warrant Shares for all Warrants (including previously issued
                  Added Warrants) and the denominator is Original Warrant Shares
                  for all Warrants (including previously issued Added Warrants);
                  over

                           (y) the aggregate Outstanding Warrant Shares for all
                  Warrants (including previously issued Added Warrants);

         the terms of such Added Warrants (including, but not limited, to term
         of exercisability, exercise price, manner and limitations, if any, on
         exercise, registration rights) shall be the same as the shall be the
         same as the applicable New Transaction Warrants issued in such New
         Transaction.

                  (iii) The Company covenants and agrees that, any of the
foregoing provisions of this Section 4(g) or any other provision of this
Agreement or any of the other Transaction Agreements to the contrary
notwithstanding, it will not without the prior written consent of a Majority in
Interest of the Holders in each instance (which consent is in the sole
discretion of the Holders and may be withheld for any reason or for no reason
whatsoever),

         (A) during the New Transaction Period, enter into any New Transaction
         where such transaction provides for a variable conversion price or a
         variable exercise price; provided, however, that this Section 4 (g)
         (iii) (A) shall not apply to a provision in a debenture or similar
         instrument, including without limitation, a preferred equity security
         (howsoever denominated; a "New Debenture") representing an obligation
         to repay the amount loaned or advanced by a New Investor to the Company
         in a New Transaction and represented by the New Debenture (the "New
         Debenture Original Principal") which provides that (i) the Company
         shall be obligated to repay on a monthly or less frequent basis,
         beginning no earlier than three months after the issuance of the New
         Debenture, a fixed amount of the New Debenture Original Principal (not
         to exceed 4.77% per month of such New Debenture Original Principal),
         together with all accrued interest due and payable thereon and (ii) if
         such required periodic payment may be paid in

<PAGE>

         shares of Common Stock, the number of shares to be issued pursuant to
         such provision shall be based on (x) the Regular VWAP for the ten (10)
         Trading Days prior to the relevant scheduled payment date, multiplied
         by (y) a percentage no lower than seventy-five percent (75%).

         (B) during the period commencing on the Closing Date and continuing
         through the Effective Date, enter into any New Transaction whatsoever,
         and

         (C) during the period commencing on the Effective Date and continuing
         through the earlier of (i) the date which is the sixth month
         anniversary of the Effective Date or (ii) the date on which the
         aggregate principal amount of all outstanding Debentures is twenty-five
         percent (25%) or less of the Aggregate Purchase Price, enter into any
         New Transaction where such New Transaction provides for any
         registration rights (including, but not limited to demand or piggy-back
         registration rights) to any one or more of the New Investors in such
         New Transaction.

The Company acknowledges that each of the foregoing provisions is independent of
the others and that a breach of any of the foregoing provisions might result in
adjustments referred to in other provisions of this Section 4(g) and, in
addition (and not in lieu of such adjustments, if any) shall constitute an event
of default under the Debenture and the other Transaction Agreements. The Company
is aware that if such event of default occurs, a Holder of a Debenture will have
certain redemption rights contemplated by the Debenture.

                  (iv) Nothing in the foregoing provisions reflects either an
obligation on the part of any Buyer to participate in any New Transaction or a
limitation on any Buyer from participating in any New Transaction.

                  (v) Any of the foregoing provisions of this Section 4(g) or
any other provision of this Agreement or any of the other Transaction Agreements
to the contrary notwithstanding, the Company shall not engage in any offers,
sales or other transactions of its securities which would adversely affect the
exemption from registration available for the transactions contemplated by the
Transaction Agreements.

                  (vi) The Company agrees that, prior to the Effective Date, the
Company will not file any registration statement for the sale of shares by the
Company or any other stockholder other than the Registration Statement
contemplated by the Registration Rights Agreement (or amendments to such
Registration Statement) and other than (x) a registration statement on Form S-8
(and any post-effective amendments thereto) and (y) a post-effective
registration statement with respect to any registration statement which was
declared effective prior to the Closing Date.

                  H. COMPANY PRINCIPAL'S AGREEMENTS.

                  (i) The Company hereby agrees that, no later than the Closing
Date, the Company will cause each of its principal officers and all of its
directors (each, a "Company Principal"), and certain Persons who are related to
or controlled by such Company Principal, to execute and deliver an agreement
(each, a "Company Principal's Agreement") regarding limitations on the sale or
other disposition of the shares of the Company's Common Stock (or instruments
convertible into or exercisable for such shares) held by such Company Principal
or other Principal (as defined in the Company Principal's Agreement), except
that, notwithstanding its terms, the Company Principal's Agreement will be
deemed not apply to the sale of shares of Common Stock bought by a Principal in
open market transactions. Subject to the foregoing, each Company Principal's
Agreement shall be substantially in the form set forth in ANNEX VII attached
hereto.

                  (ii) In addition, under certain circumstances as contemplated
by the definition of "New Transaction" in this Agreement, certain future
issuances by the Company to persons identified in clause (g) of such definition
are conditioned on such shares being subject to a Company Principal's Agreement
being executed by the relevant party (who, whether or not included in the
definition of Company Principal in the preceding subparagraph (i), shall, for
purposes of this Section 4(h), be deemed to be a "Company Principal" identified
in such definition). The Company covenants that it will obtain such executed
Company Principal's Agreement from the relevant party

<PAGE>

no later than the issuance of the relevant security to such party and that it
will promptly provide a copy thereof to the Document Escrow Agent on behalf of
the Buyer and the Other Buyers.

                  I. AVAILABLE SHARES.

                  (i) The Company shall have at all times authorized and
reserved for issuance, free from preemptive rights, a number of shares (the
"Reserved Amount") at least equal to one hundred and fifty percent (150%) of the
sum of (x) the number of shares of Common Stock issuable as may be required, at
any time, to satisfy the conversion rights of the Holders of principal on all
outstanding Convertible Debentures plus interest thereon through the Maturity
Date (assuming for such purposes that interest is paid in shares at the
Conversion Price), plus one hundred percent (100%) of the sum of (y) the number
of shares issuable upon exercise of all outstanding Warrants held by all Holders
(in each case, whether any of such outstanding Convertible Debentures or
Warrants were originally issued to the Holder, the Buyer or to any other party
and without regard to any restrictions which might limit any Holder's right to
convert any of the Debentures or to exercise any of the Warrants held by any
Holder).

                  (ii) The Reserved Amount shall be determined on the Closing
Date and after each New Transaction Closing Date, and thereafter on the first
Trading Day after the end of each subsequent calendar quarter, and the number of
shares to be reserved shall be based on (q) all outstanding Debentures and the
Conversion Price which would have been applicable as of such date and (r) all
unexercised Warrants as of such date. The Reserved Amount determined on such
date shall remain the Reserved Amount until the next New Transaction Closing
Date or quarterly determination, as the case may be. The Company shall give
written instructions to the Transfer Agent to reserve for issuance to the Buyer
the number of shares equal to the Reserved Amount. The Company will, at the
request of the Buyer (which request shall not be made more frequently than once
a year), provide written confirmation, certified by an executive officer of the
Company, of the number of shares then reserved for the Buyer and that the
instructions referred to in the preceding sentence have been given to the
Transfer Agent.

                  J. PUBLICITY, FILINGS, RELEASES, ETC. Each of the parties
agrees that it will not disseminate any information relating to the Transaction
Agreements or the transactions contemplated thereby, including issuing any press
releases, holding any press conferences or other forums, or filing any reports
(collectively, "Publicity"), without giving the other party reasonable advance
notice and an opportunity to comment on the contents thereof. Neither party will
include in any such Publicity any statement or statements or other material to
which the other party reasonably objects, unless in the reasonable opinion of
counsel to the party proposing such statement, such statement is legally
required to be included. In furtherance of the foregoing, the Company will
provide to the Investor's Counsel (as defined in the Registration Rights
Agreement) drafts of the applicable text the first or initial filing of a
Current Report on Form 8-K or a Quarterly or Annual Report on Form 10-Q or 10-K
(or equivalent SB forms), as the case may be, intended to be made with the SEC
which refers to the Transaction Agreements or the transactions contemplated
thereby as soon as practicable (but at least two (2) Trading Day before such
filing will be made) and will not include in such filing (or any other filing
filed before then) any statement or statements or other material to which the
other party reasonably objects, unless in the reasonable opinion of counsel to
the party proposing such statement, such statement is legally required to be
included. Notwithstanding the foregoing, each of the parties hereby consents to
the inclusion of the text of the Transaction Agreements in filings made with the
SEC (but any descriptive text accompanying or part of such filing shall be
subject to the other provisions of this paragraph). Notwithstanding, but subject
to, the foregoing provisions of this Section 4(j), the Company will, after the
Closing Date, promptly issue a press release and file a Current Report on Form
8-K or, if appropriate, include a disclosure in a quarterly or annual report on
the appropriate form, referring to the transactions contemplated by the
Transaction Agreements.

                  K. INDEPENDENT NATURE OF BUYERS' OBLIGATIONS AND RIGHTS. The
obligations of each Buyer under the Transaction Agreements are several and not
joint with the obligations of any other Buyer, and no Buyer shall be responsible
in any way for the performance of the obligations of any Other Buyer under any
one or more of the Transaction Agreements. The decision of each Buyer or Other
Buyer to purchase Purchased Securities pursuant to the Transaction Agreements
has been made by such Buyer independently of any Other Buyer and

<PAGE>

independently of any information, materials, statements or opinions as to the
business, affairs, operations, assets, properties, liabilities, results of
operations, condition (financial or otherwise) or prospects of the Company or of
its subsidiaries, if any, which may been made or given by any Other Buyer or any
of their respective officers, directors, principals, employees, agents, counsel
or representatives (collectively, including the Buyer, the "Buyer
Representatives"). No Buyer Representative shall have any liability to any Other
Buyer or the Company relating to or arising from any such information,
materials, statements or opinions, if any. Each Buyer acknowledges that no Other
Buyer has acted as agent for such Buyer in connection with making its investment
hereunder and that no Buyer will be acting as agent of such Other Buyer in
connection with monitoring its investment in the Purchased Securities or
enforcing its rights under the Transaction Agreements. Each Buyer shall be
entitled to independently protect and enforce its rights, including without
limitation the rights arising out of this Agreement or out of the other
Transaction Agreements, and it shall not be necessary for any Other Buyer to be
joined as an additional party in any proceeding for such purpose. The Company
acknowledges that, for reasons of administrative convenience, (x) the
Transaction Agreements have been prepared by counsel for one of the Buyers and
such counsel does not represent all of the Buyers with respect to the
transactions contemplated hereby, and each other Buyer has retained its own
counsel (or had the opportunity to do so) with respect to such transactions, and
(y) the Company has elected to provide each of the Buyers with the same
Transaction Agreements for the purpose of closing a transaction with multiple
Buyers and not because it was required or requested to do so by any Buyer. In
furtherance of the foregoing, and not in limitation thereof, the Company
acknowledges that nothing contained in this Agreement or in any Transaction
Agreement, and no action taken by any Buyer pursuant thereto, shall be deemed to
constitute any two or more Buyers as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Buyers are
in any way acting in concert or as a group with respect to such obligations or
the transactions contemplated by the Transaction Agreements.

                  L. EQUAL TREATMENT OF BUYERS. No consideration shall be
offered or paid to any person to amend or consent to a waiver or modification of
any provision of any of the Transaction Agreements unless the same consideration
is also offered to all of the parties to the Transaction Agreements.

                  M. INDEPENDENT INVESTMENT DECISION. No Buyer has agreed to act
with any Other Buyer for the purpose of acquiring, holding, voting or disposing
of the Securities purchased hereunder for purposes of Section 13(d) under the
Exchange Act, and each Buyer is acting independently with respect to its
investment in the Securities. The decision of each Buyer to purchase Purchased
Securities pursuant to this Agreement has been made by such Buyer independently
of any other purchase and independently of any information, materials,
statements or opinions as to the business, affairs, operations, assets,
properties, liabilities, results of operations, condition (financial or
otherwise) or prospects of the Company or its subsidiaries wh ich may have made
or given by any Other Buyer or by any agent or employee of any Other Buyer, and
no Buyer or any of its agents or employees shall have any liability to any Other
Buyer (or any other person) relating to or arising from any such information,
materials, statements or opinions.

                  N. NASD RULE 2710. The Company is aware that the Corporate
Financing Rule 2710 ("NASD Rule 2710") of the National Association of Securities
Dealers ("NASD") is or may become applicable to the transactions contemplated by
the Transaction Agreements or to the sale by a Holder of any of the Securities.
If NASD Rule 2710 is so applicable, the Company shall, to the extent required by
such rule, timely make any filings and cooperate with any broker or selling
stockholder in respect of any consents, authorizations or approvals that may be
necessary for the NASD to timely and expeditiously permit the stockholder to
sell the securities.

                  O. KEEPING OF RECORDS AND BOOKS OF ACCOUNT. The Company shall
keep and cause each subsidiary, if any, to keep adequate records and books of
account, in which complete entries will be made in accordance with GAAP
consistently applied, reflecting all financial transactions of the Company and
such subsidiaries, and in which, for each fiscal year, all proper reserves for
depreciation, depletion, obsolescence, amortization, taxes, bad debts and other
purposes in connection with its business shall be made.

                  5. TRANSFER AGENT INSTRUCTIONS.

                  A. The Company warrants that, with respect to the Securities,
other than the stop transfer instructions to give effect to Section 4(a) hereof,
it will give the Transfer Agent no instructions inconsistent with instructions
to issue Common Stock from time to time upon conversion of the Debentures or
exercise of the Warrants or in connection with the issuance of Payment Shares,
as may be applicable from time to time, in such amounts as specified from time
to time by the Company to the Transfer Agent, bearing the restrictive legend
specified in Section 4(b) of this Agreement prior to registration of the Shares
under the 1933 Act, registered in the name of the Buyer or its nominee and in
such denominations to be specified by the Holder in connection therewith. Except
as so provided, the Shares shall otherwise be freely transferable on the books
and records of the Company as and to the extent provided in this Agreement and
the other Transaction Agreements. Nothing in this Section shall affect in any
way the Buyer's obligations and agreement to comply with all applicable
securities laws upon resale of the Securities. If the Buyer provides the Company
with an opinion of counsel reasonably satisfactory to the Company that
registration of a resale by the Buyer of any of the Securities in accordance
with clause (1)(B) of Section 4(a) of this Agreement is not required under the
1933 Act or upon request from a Holder while the Registration Statement is
effective, the Company shall (except as provided in clause (2) of Section 4(a)
of this Agreement) permit the transfer of the Securities and, in the case of the
Conversion Shares, the Warrant Shares or the Payment Shares, as may be
applicable, promptly instruct the Transfer Agent to issue one or more
certificates for Common Stock without legend in such name and in such
denominations as specified by the Buyer.

                  B. (i) The Company understands that a delay in the delivery of
Conversion Certificates, whether on conversion of the Debenture and/or in
payment of accrued interest or on exercise of the Warrants, beyond the relevant
Delivery Date (as defined in the Debenture or Warrant, as the case may be) could
result in economic loss to the Holder. As compensation to the Holder for such
loss, in addition to any other remedies at law, the Company agrees to pay late
payments to the Holder for late issuance of the Conversion Certificates in
accordance with the following schedule (where "No. Business Days Late" is
defined as the number of Trading Days beyond two (2) Trading Days after the
Delivery Date):(5)

_____________________________
(5) Example: Notice of Conversion or Notice of Exercise is delivered on Monday,
October 2, 2006. The Delivery Date would be Thursday, October 5 (the third
Trading Day after such delivery). If the certificate is delivered by Monday,
October 9 (2 Trading Days after the Delivery Date), no payment under this
provision is due. If the certificates are delivered on October 10, that is 1
"Trading Day Late" in the table below; if delivered on October 17, that is 6
"Trading Days Late" in the table.

<PAGE>

                                   Late Payment For Each $10,000
                                   of Principal or Interest Being Converted or
 NO. BUSINESS DAYS LATE      OF EXERCISE PRICE OF WARRANT BEING EXERCISED

                       1                                   $100
                       2                                   $200
                       3                                   $300
                       4                                   $400

                       7                                   $700
                       8                                   $800
                       9                                   $900
                       10                                  $1,000
                       >10                                 $1,000 + $200 for
                                                           each Business Day
                                                           Late beyond 10 days

The Company shall pay any payments incurred under this Section in immediately
available funds upon demand. Nothing herein shall limit the Holder's right to
pursue actual damages for the Company's failure to issue and deliver the
Conversion Certificates to the Holder within a reasonable time. Furthermore, in
addition to any other remedies which may be available to a Holder, in the event
that the Company fails for any reason to effect delivery of such Conversion
Certificates within two (2) Trading Days after the Delivery Date, the Converting
Holder will be entitled to revoke the relevant Notice of Conversion or Notice of
Exercise by delivering a notice to such effect to the Company prior to the
Converting Holder's receipt of the relevant Conversion Certificates, whereupon
the Company and the Converting Holder shall each be restored to their respective
positions immediately prior to delivery of such Notice of Conversion or Notice
of Exercise, as the case may be; PROVIDED, HOWEVER, that any payments
contemplated by this Section 5(b) of this Agreement which have accrued through
the date of such revocation notice shall remain due and owing to the Converting
Holder notwithstanding such revocation.

                           (ii) If, by the tenth Trading Day after the relevant
Delivery Date, the Company fails for any reason to deliver the Conversion
Certificates, but at any time after the Delivery Date, the Converting Holder
purchases, in an arm's-length open market transaction or otherwise, shares of
Common Stock (the "Covering Shares") in order to make delivery in satisfaction
of a sale of Common Stock by the Converting Holder (the "Sold Shares"), which
delivery such Converting Holder anticipated to make using the shares to be
issued upon such conversion (a "Buy-In"), the Converting Holder shall have the
right to require the Company to pay to the Converting Holder, in addition to and
not in lieu of the amounts contemplated in other provisions of the Transaction
Agreements, including, but not limited to, the provisions of the immediately
preceding Section 5(b)(i)), the Buy-In Adjustment Amount (as defined below). The
"Buy-In Adjustment Amount" is the amount equal to the number of Sold Shares
multiplied by the excess, if any, of (x) the Holder's total purchase price per
share (including brokerage commissions, if any) for the Covering Shares over (y)
the net proceeds per share (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 immediately upon
demand by the Converting 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 Company will be required to pay to the Holder
will be $1,000.

                  C. The provisions of this paragraph apply on or after the
Effective Date. After such Effective Date, the Company will issue Shares without
legend and without transfer restrictions on the books of the Transfer Agent,
and, at the request of the Holder, will use it best efforts to have previously
issued certificates representing the Shares re-issued without legend and without
transfer restrictions on the books of the Transfer

<PAGE>

Agent. In lieu of delivering physical certificates representing the Common Stock
issuable upon conversion of the Debenture or exercise of a Warrant or at the
request of the Holder with respect to any Shares previously issued, provided the
Transfer Agent is participating in the Depository Trust Company ("DTC") Fast
Automated Securities Transfer program, upon request of the Holder and the
Holder's compliance with the provisions contained in this paragraph, so long as
the certificates therefor do not bear a legend and the Holder thereof is not
obligated to return such certificate for the placement of a legend thereon, the
Company shall use its best efforts to cause the Transfer Agent to electronically
transmit to the Holder the Common Stock issuable upon conversion of the
Debenture or exercise of the Warrant or in replacement of any Shares previously
issued by crediting the account of Holder's Prime Broker with DTC through its
Deposit Withdrawal Agent Commission system. The Company specifically
acknowledges that, as of the date hereof and as of the Closing Date, the
Transfer Agent is participating in the DTC program and the Company is not aware
of any plans of the Transfer Agent to terminate such participation. While any
Holder holds Registrable Securities, the Company will not appoint any transfer
agent which does not participate in the DTC program.

                  D. The Company shall assume any fees or charges of the
Transfer Agent or Company counsel regarding (i) the removal of a legend or stop
transfer instructions with respect to Registrable Securities, and (ii) the
issuance of certificates or DTC registration to or in the name of the Holder or
the Holder's designee or to a transferee as contemplated by an effective
Registration Statement. Notwithstanding the foregoing, it shall be the Holder's
responsibility to obtain all needed formal requirements (specifically: medallion
guarantee and prospectus delivery compliance) in connection with any electronic
issuance of shares of Common Stock.

                  E. The Holder of a Debenture or a Warrant shall be entitled to
exercise its conversion or exercise privilege with respect to the Debenture or
the Warrant, as the case may be, notwithstanding the commencement of any case
under 11 U.S.C. ss.101 ET SEQ. (the "Bankruptcy Code"). In the event the Company
is a debtor under the Bankruptcy Code, the Company hereby waives, to the fullest
extent permitted, any rights to relief it may have under 11 U.S.C. ss.362 in
respect of such holder's exercise privilege. The Company hereby waives, to the
fullest extent permitted, any rights to relief it may have under 11 U.S.C.
ss.362 in respect of the conversion of the Debenture or the exercise of the
Warrant. The Company agrees, without cost or expense to such Holder, to take or
to consent to any and all action necessary to effectuate relief under 11 U.S.C.
ss.362.

                  F. The Company will authorize the Transfer Agent to give
information relating to the Company directly to the Holder or the Holder's
representatives upon the request of the Buyer or any such representative, to the
extent such information relates to (i) the status of shares of Common Stock
issued or claimed to be issued to the Holder in connection with a Notice of
Conversion or a Notice of Exercise, or (ii) the aggregate number of outstanding
shares of Common Stock of all stockholders (as a group and not individually) as
of a current or other specified date. At the request of the Holder, the Company
will provide the Holder with a copy of the authorization so given to the
Transfer Agent.

                  6. CLOSING DATE.

                  A. The Closing Date shall occur on the date which is the first
Trading Day after each of the conditions contemplated by Sections 7 and 8 hereof
shall have either been satisfied or been waived by the party in whose favor such
conditions run.

                  B. The closing of the purchase and issuance of Debentures and
Warrants shall occur on the Closing Date at the offices of the Escrow Agent.

                  C. Notwithstanding anything to the contrary contained herein,
on the Closing Date upon satisfaction of the conditions set forth in Sections 7
and 8 hereof and as provided in the Joint Escrow Instructions, the Document
Escrow Agent will be authorized to (i) authorize the Funds Escrow Agent to
release the relevant Escrow Funds to the Company and to others, as provided in
the Joint Escrow Instructions, and (ii) as provided herein, release to the Buyer
the relevant Certificates issued to the Buyer.

                  7. CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

                  The Buyer understands that the Company's obligation to sell

                  G. There shall not be in effect any law, rule or regulation

                  9. INDEMNIFICATION AND REIMBURSEMENT.

                  A. (i) The Company agrees to indemnify and hold harmless the
Buyer and its officers, directors, employees, and agents, and each Buyer Control
Person from and against any losses, claims, damages, liabilities or expenses
incurred (collectively, "Damages"), joint or several, and any action in respect
thereof to which the Buyer, its partners, Affiliates, officers, directors,
employees, and duly authorized agents, and any such Buyer Control Person becomes
subject to, resulting from, arising out of or relating to any misrepresentation,
breach of warranty or nonfulfillment of or failure to perform any covenant or
agreement on the part of Company contained in this Agreement, as such Damages
are incurred, except to the extent such Damages result primarily from Buyer's
failure to perform any covenant or agreement contained in this Agreement or the
Buyer's or its officer's, director's, employee's, agent's or Buyer Control
Person's illegal or willful misconduct, gross negligence, recklessness or bad
faith (in each case, as determined by a non-appealable judgment to such effect)
in performing its obligations under this Agreement.

                           (ii) The Company hereby agrees that, if the Buyer,
other than by reason of its gross negligence or willful misconduct or by reason
of its trading of the Common Stock in a manner that is illegal under the federal
securities laws (in each case, as determined by a non-appealable judgment to
such effect), (x) becomes involved in any capacity in any action, proceeding or
investigation brought by any stockholder of the Company, in connection with or
as a result of the consummation of the transactions contemplated by this
Agreement or the other Transaction Agreements, or if the Buyer is impleaded in
any such action, proceeding or investigation by any Person, or (y) becomes
involved in any capacity in any action, proceeding or investigation brought by
the SEC, any self-regulatory organization or other body having jurisdiction,
against or involving the Company or in connection with or as a result of the
consummation of the transactions contemplated by this Agreement or the other
Transaction Agreements, or (z) is impleaded in any such action, proceeding or
investigation by any Person, then in any such case, the Company shall indemnify,
defend and hold harmless the Buyer from and against and in respect of all
losses, claims, liabilities, damages or expenses resulting from, imposed upon or
incurred by the Buyer, directly or indirectly, and reimburse such Buyer for its
reasonable legal and other expenses (including the cost of any investigation and
preparation) incurred in connection therewith, as such expenses are incurred.
The indemnification and reimbursement obligations of the Company under this
paragraph shall be in addition to any liability which the Company may otherwise
have, shall extend upon the same terms and conditions to any Affiliates of the
Buyer who are actually named in such action, proceeding or investigation, and
partners, directors, agents, employees and Buyer Control Persons (if any), as
the case may be, of the Buyer and any such Affiliate, and shall be binding upon
and inure to the benefit of any successors, assigns, heirs and personal
representatives of the Company, the Buyer, any such Affiliate and any such
Person.

                  B. All claims for indemnification by any Indemnified Party (as
defined below) under this Section shall be asserted and resolved as follows:

                           (i) In the event any claim or demand in respect of
which any Person claiming indemnification under any provision of this Section
(an "Indemnified Party") might seek indemnity under paragraph (a) of this
Section is asserted against or sought to be collected from such Indemnified
Party by a Person other than a party hereto or an Affiliate thereof (a "Third
Party Claim"), the Indemnified Party shall deliver a written notification,
enclosing a copy of all papers served, if any, and specifying the nature of and
basis for such Third Party Claim and for the Indemnified Party's claim for
indemnification that is being asserted under any provision of this Section
against any Person (the "Indemnifying Party"), together with the amount or, if
not then reasonably ascertainable, the estimated amount, determined in good
faith, of such Third Party Claim (a "Claim Notice") with reasonable promptness
to the Indemnifying Party. If the Indemnified Party fails to provide the Claim
Notice with reasonable promptness after the Indemnified Party receives notice of
such Third Party Claim, the Indemnifying

<PAGE>

Party shall not be obligated to indemnify the Indemnified Party with respect to
such Third Party Claim to the extent that the Indemnifying Party's ability to
defend has been prejudiced by such failure of the Indemnified Party. The
Indemnifying Party shall notify the Indemnified Party as soon as practicable
within the period ending thirty (30) calendar days following receipt by the
Indemnifying Party of either a Claim Notice or an Indemnity Notice (as defined
below) (the "Dispute Period") whether the Indemnifying Party disputes its
liability or the amount of its liability to the Indemnified Party under this
Section and whether the Indemnifying Party desires, at its sole cost and
expense, to defend the Indemnified Party against such Third Party Claim. The
following provisions shall also apply.

         (x) If the Indemnifying Party notifies the Indemnified Party within the
         Dispute Period that the Indemnifying Party desires to defend the
         Indemnified Party with respect to the Third Party Claim pursuant to
         this paragraph (b) of this Section, then the Indemnifying Party shall
         have the right to defend, with counsel reasonably satisfactory to the
         Indemnified Party, at the sole cost and expense of the Indemnifying
         Party, such Third Party Claim by all appropriate proceedings, which
         proceedings shall be vigorously and diligently prosecuted by the
         Indemnifying Party to a final conclusion or will be settled at the
         discretion of the Indemnifying Party (but only with the consent of the
         Indemnified Party in the case of any settlement that provides for any
         relief other than the payment of monetary damages or that provides for
         the payment of monetary damages as to which the Indemnified Party shall
         not be indemnified in full pursuant to paragraph (a) of this Section).
         The Indemnifying Party shall have full control of such defense and
         proceedings, including any compromise or settlement thereof; provided,
         however, that the Indemnified Party may, at the sole cost and expense
         of the Indemnified Party, at any time prior to the Indemnifying Party's
         delivery of the notice referred to in the first sentence of this
         subparagraph (x), file any motion, answer or other pleadings or take
         any other action that the Indemnified Party reasonably believes to be
         necessary or appropriate protect its interests; and provided further,
         that if requested by the Indemnifying Party, the Indemnified Party
         will, at the sole cost and expense of the Indemnifying Party, provide
         reasonable cooperation to the Indemnifying Party in contesting any
         Third Party Claim that the Indemnifying Party elects to contest. The
         Indemnified Party may participate in, but not control, any defense or
         settlement of any Third Party Claim controlled by the Indemnifying
         Party pursuant to this subparagraph (x), and except as provided in the
         preceding sentence, the Indemnified Party shall bear its own costs and
         expenses with respect to such participation. Notwithstanding the
         foregoing, the Indemnified Party may take over the control of the
         defense or settlement of a Third Party Claim at any time if it
         irrevocably waives its right to indemnity under paragraph (a) of this
         Section with respect to such Third Party Claim.

         (y) If the Indemnifying Party fails to notify the Indemnified Party
         within the Dispute Period that the Indemnifying Party desires to defend
         the Third Party Claim pursuant to paragraph (b) of this Section, or if
         the Indemnifying Party gives such notice but fails to prosecute
         vigorously and diligently or settle the Third Party Claim, each in a
         reasonable manner, or if the Indemnifying Party fails to give any
         notice whatsoever within the Dispute Period, then the Indemnified Party
         shall have the right to defend, at the sole cost and expense of the
         Indemnifying Party, the Third Party Claim by all appropriate
         proceedings, which proceedings shall be prosecuted by the Indemnified
         Party in a reasonable manner and in good faith or will be settled at
         the discretion of the Indemnified Party (with the
          consent of the Indemnifying Party, which consent will not be
         unreasonably withheld). The Indemnified Party will have full control of
         such defense and proceedings, including any compromise or settlement
         thereof; provided, however, that if requested by the Indemnified Party,
         the Indemnifying Party will, at the sole cost and expense of the
         Indemnifying Party, provide reasonable cooperation to the Indemnified
         Party and its counsel in contesting any Third Party Claim which the
         Indemnified Party is contesting. Notwithstanding the foregoing
         provisions of this subparagraph (y), if the Indemnifying Party has
         notified the Indemnified Party within the Dispute Period that the
         Indemnifying Party disputes its liability or the amount of its
         liability hereunder to the Indemnified Party with respect to such Third
         Party Claim and if such dispute is resolved in favor of the
         Indemnifying Party in the manner provided in

<PAGE>

         subparagraph(z) below, the Indemnifying Party will not be required to
         bear the costs and expenses of the Indemnified Party's defense pursuant
         to this subparagraph (y) or of the Indemnifying Party's participation
         therein at the Indemnified Party's request, and the Indemnified Party
         shall reimburse the Indemnifying Party in full for all reasonable costs
         and expenses incurred by the Indemnifying Party in connection with such
         litigation. The Indemnifying Party may participate in, but not control,
         any defense or settlement controlled by the Indemnified Party pursuant
         to this subparagraph (y), and the Indemnifying Party shall bear its own
         costs and expenses with respect to such participation.

         (z) If the Indemnifying Party notifies the Indemnified Party that it
         does not dispute its liability or the amount of its liability to the
         Indemnified Party with respect to the Third Party Claim under paragraph
         (a) of this Section or fails to notify the Indemnified Party within the
         Dispute Period whether the Indemnifying Party disputes its liability or
         the amount of its liability to the Indemnified Party with respect to
         such Third Party Claim, the amount of Damages specified in the Claim
         Notice shall be conclusively deemed a liability of the Indemnifying
         Party under paragraph (a) of this Section and the Indemnifying Party
         shall pay the amount of such Damages to the Indemnified Party on
         demand. If the Indemnifying Party has timely disputed its liability or
         the amount of its liability with respect to such claim, the
         Indemnifying Party and the Indemnified Party shall proceed in good
         faith to negotiate a resolution of such dispute; provided, however,
         that if the dispute is not resolved within thirty (30) days after the
         Claim Notice, the Indemnifying Party shall be entitled to institute
         such legal action as it deems appropriate.

                  C. The indemnity agreements contained herein shall be in
addition to (i) any cause of action or similar rights of the indemnified party
against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to.

                  10. JURY TRIAL WAIVER. The Company and the Buyer hereby waive
a trial by jury in any action, proceeding or counterclaim brought by either of
the Parties hereto against the other in respect of any matter arising out or in
connection with the Transaction Agreements.

                  11. SPECIFIC PERFORMANCE. The Company and the Buyer
acknowledge and agree that irreparable damage would occur in the event that any
provision of this Agreement or any of the other Transaction Agreements were not
performed in accordance with its specific terms or were otherwise breached. It
is accordingly agreed that the parties (including any Holder) shall be entitled
to an injunction or injunctions, without (except as specified below) the
necessity to post a bond, to prevent or cure breaches of the provisions of this
Agreement or such other Transaction Agreement and to enforce specifically the
terms and provisions hereof or thereof, this being in addition to any other
remedy to which any of them may be entitled by law or equity; provided, however
that the Company, upon receipt of a Notice of Conversion or a Notice of
Exercise, may not fail or refuse to deliver the stock certificates and the
related legal opinions, if any, based on any claim that the Holder has violated
any provision hereof or for any other reason, unless the Company has first
posted a bond for one hundred fifty percent (150%) of the principal amount and
then obtained a court order specifically directing it not to deliver said stock
certificates to the Holder. This provision is deemed incorporated by reference
into each of the Transaction Agreements as if set forth therein in full.

                  12. GOVERNING LAW: MISCELLANEOUS.

                  A. This Agreement shall be governed by and interpreted in
accordance with the laws of the State of New York for contracts to be wholly
performed in such state and without giving effect to the principles thereof
regarding the conflict of laws. Each of the parties consents to the exclusive
jurisdiction of the federal courts whose districts encompass any part of the
County of New York or the state courts of the State of New York sitting in the
County of New York in connection with any dispute arising under this Agreement
or any of the other Transaction Agreements and hereby waives, to the maximum
extent permitted by law, any objection, including any objection based on FORUM
NON CONVENIENS, to the bringing of any such proceeding in such jurisdictions or
to any

<PAGE>

claim that such venue of the suit, action or proceeding is improper. To
the extent determined by such court, the Company shall reimburse the Buyer for
any reasonable legal fees and disbursements incurred by the Buyer in enforcement
of or protection of any of its rights under any of the Transaction Agreements.
Nothing in this Section shall affect or limit any right to serve process in any
other manner permitted by law.

                  B. Failure of any party to exercise any right or remedy under
this Agreement or otherwise, or delay by a party in exercising such right or
remedy, shall not operate as a waiver thereof.

                  C. This Agreement shall inure to the benefit of and be binding
upon the successors and assigns of each of the parties hereto.

                  D. All pronouns and any variations thereof refer to the
masculine, feminine or neuter, singular or plural, as the context may require.

                  E. A facsimile transmission of this signed Agreement shall be
legal and binding on all parties hereto.

                  F. This Agreement may be signed in one or more counterparts,
each of which shall be deemed an original.

                  G. The headings of this Agreement are for convenience of
reference and shall not form part of, or affect the interpretation of, this
Agreement.

                  H. If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement or the
validity or enforceability of this Agreement in any other jurisdiction.

                  I. This Agreement may be amended only by an instrument in
writing signed by the party to be charged with enforcement thereof.

                  J. This Agreement supersedes all prior agreements and
understandings among the parties hereto with respect to the subject matter
hereof.

                  K. All dollar amounts referred to or contemplated by this
Agreement or any other Transaction Agreement shall be deemed to refer to US
Dollars, unless otherwise explicitly stated to the contrary.

                  13. NOTICES. Any notice required or permitted hereunder shall
be given in writing (unless otherwise specified herein) and shall be deemed
effectively given on the earliest of

                           (a) the date delivered, if delivered by personal
