    Section
2.                                Interest.

    


    a) Payment of Interest in Cash
or Kind. The Company shall pay interest to the Holder on the aggregate
unconverted and then outstanding principal amount of this Debenture at the rate
of 8% per annum, payable quarterly on January 1, April 1, July 1 and October 1,
beginning on the first such date after the Original Issue Date, on each

Optional Redemption Date (as to that principal amount then being redeemed) and
on the Maturity Date (each such date, an “Interest Payment
Date”) (if any Interest Payment Date is not a Business Day, then the

or, at the Company’s option, in duly authorized, validly issued, fully paid and
non-assessable shares of Common Stock at the Interest Conversion Rate (the
dollar amount to be paid in shares, the “Interest Share
Amount”) or a combination thereof; provided, however, that payment
in shares of Common Stock may only occur if (i) all of the Equity Conditions
have been met (unless waived by the Holder in writing) during the 20 Trading
Days immediately prior to the applicable Interest Payment Date  (the
“Interest Notice
Period”) and through and including the date such shares of Common Stock
are actually issued to the Holder, (ii) the Company shall have given the Holder
notice in accordance with the notice requirements set forth below and (iii) as
to such Interest Payment Date, prior to such Interest Notice Period (but not
more than five (5) Trading Days prior to the commencement of such Interest
Notice Period), the Company shall have delivered to the Holder’s account with
The Depository Trust Company a number of shares of Common Stock to be applied
against such Interest Share Amount equal to the quotient of (x) the applicable
Interest Share Amount divided by (y) the lesser of the (i) then Conversion Price
and (ii) the Interest Conversion Rate assuming for such purposes that the
Interest Payment Date is the Trading Day immediately prior to the commencement
of the Interest Notice Period (the “Interest Conversion
Shares”).

    


    b) Company’s Election to Pay
Interest in Cash or Shares of Common Stock.  Subject to the
terms and conditions herein, the decision whether to pay interest hereunder in
cash, shares of Common Stock or a combination thereof shall be at the sole
discretion of the Company.  Prior to the commencement of any Interest
Notice Period, the Company shall deliver to the Holder a written notice of its
election to pay interest hereunder on the applicable Interest Payment Date
either in cash, shares of Common Stock or a combination thereof and the Interest
Share Amount as to the applicable Interest Payment Date, provided that the
Company may indicate in such notice that the election contained in such notice
shall apply to future Interest Payment Dates until revised by a subsequent
notice.  During any Interest Notice Period, the Company’s election
(whether specific to an Interest Payment Date or continuous) shall be
irrevocable as to such Interest Payment Date.  Subject to the
aforementioned conditions, failure to timely deliver such written notice to the
Holder shall be deemed an election by the Company to pay the interest on such
Interest Payment Date in cash.  At any time the Company delivers a
notice to the Holder of its election to pay the interest in shares of Common
Stock, the Company shall timely file a prospectus supplement pursuant to Rule
424 disclosing such election.  The aggregate number of shares of
Common Stock otherwise issuable to the Holder on an Interest Payment Date shall
be reduced by the number of Interest Conversion Shares previously issued to the
Holder in connection with such Interest Payment Date.

    


    c) Interest
Calculations. Interest shall be calculated on the basis of a 360-day
year, consisting of twelve 30 calendar day periods, and shall accrue daily
commencing on the Original Issue Date until payment in full of the outstanding
principal, together with all accrued and unpaid interest, liquidated damages and
other amounts which may become due hereunder, has been made.  Payment
of interest in shares of Common Stock (other than the Interest Conversion Shares
issued prior to an Interest Notice Period) shall otherwise occur pursuant to
Section 4(d)(ii) herein and, solely for purposes of the payment of interest in
shares, the Interest Payment Date shall be deemed the Conversion
Date.  Interest shall cease to accrue with respect to any principal
amount converted, provided that, the Company actually delivers the Conversion
Shares within the time period required by Section 4(d)(ii)
herein.  Interest hereunder will be paid to the Person in whose name
this Debenture is registered on the records of the Company regarding
registration and transfers of this Debenture (the “Debenture Register”).
Except as otherwise provided herein, if at any time the Company pays interest
partially in cash and partially in shares of Common Stock to the holders of the
Debentures, then such payment of cash shall be distributed ratably among the
holders of the then-outstanding Debentures based on their (or their
predecessor’s) initial purchases of Debentures pursuant to the Purchase
Agreement.

    


    d) Late
Fee.  All overdue accrued and unpaid interest to be paid
hereunder shall entail a late fee at an interest rate equal to the lesser of 18%
per annum or the maximum rate permitted by applicable law (the “Late Fees”) which
shall accrue daily from the date such interest is due hereunder through and
including the date of actual payment in full. Notwithstanding anything to the
contrary contained herein, if, on any Interest Payment Date the Company has
elected to pay accrued interest in the form of Common Stock but the Company is
not permitted to pay accrued interest in Common Stock because it fails to
satisfy the conditions for payment in Common Stock set forth in Section 2(a)
herein, then, at the option of the Holder, the Company, in lieu of delivering
either shares of Common Stock pursuant to this Section 2 or paying the regularly
scheduled interest payment in cash, shall deliver, within three (3) Trading Days
of each applicable Interest Payment Date, an amount in cash equal to the product
of (x) the number of shares of Common Stock otherwise deliverable to the Holder
in connection with the payment of interest due on such Interest Payment Date
multiplied by (y) the highest VWAP during the period commencing on the Interest
Payment Date and ending on the Trading Day prior to the date such payment is
actually made.  If any Interest Conversion Shares are issued to the
Holder in connection with an Interest Payment Date and are not applied against
an Interest Share Amount, then the Holder shall promptly return such excess
shares to the Company.

    


    e) Prepayment.  Except
as otherwise set forth in this Debenture, the Company may not prepay any portion
of the principal amount of this Debenture without the prior written consent of
the Holder.

    


    Section
3.                      Registration of Transfers
and Exchanges.

    


    a) Different
Denominations. This Debenture is exchangeable for an equal aggregate
principal amount of Debentures of different authorized denominations, as
requested by the Holder surrendering the same.  No service charge will
be payable for such registration of transfer or exchange.

    


    b) Investment
Representations. This Debenture has been issued subject to certain
investment representations of the original Holder set forth in the Purchase
Agreement and may be transferred or exchanged only in compliance with the
Purchase Agreement and applicable federal and state securities laws and
regulations.

    


    c) Reliance on Debenture
Register. Prior to due presentment for transfer to the Company of this
Debenture, the Company and any agent of the Company may treat the Person in
whose name this Debenture is duly registered on the Debenture Register as the
owner hereof for the purpose of receiving payment as herein provided and for all
other purposes, whether or not this Debenture is overdue, and neither the
Company nor any such agent shall be affected by notice to the
contrary.

    


    Section
4.                      Conversion.

    


    a) Voluntary Conversion.
At any time after the Original Issue Date until this Debenture is no longer
outstanding, this Debenture shall be convertible, in whole or in part, into
shares of Common Stock at the option of the Holder, at any time and from time to
time (subject to the conversion limitations set forth in Section 4(c)
hereof).  The Holder shall effect conversions by delivering to the
Company a Notice of Conversion, the form of which is attached hereto as Annex A (each, a
“Notice of
Conversion”), specifying therein the principal amount of this Debenture
to be converted and the date on which such conversion shall be effected (such
date, the “Conversion
Date”).  If no Conversion Date is specified in a Notice of
Conversion, the Conversion Date shall be the date that such Notice of Conversion
is deemed delivered hereunder.  To effect conversions hereunder, the
Holder shall not be required to physically surrender this Debenture to the
Company unless the entire principal amount of this Debenture, plus all accrued
and unpaid interest thereon, has been so converted. Conversions hereunder shall
have the effect of lowering the outstanding principal amount of this Debenture
in an amount equal to the applicable conversion.  The Holder and the
Company shall maintain records showing the principal amount(s) converted and the
date of such conversion(s).  The Company may deliver an objection to
any Notice of Conversion within 1 Business Day of delivery of such Notice of
Conversion.  In the event of any dispute or discrepancy, the records
of the Holder shall be controlling and determinative in the absence of manifest
error. The Holder, and any
assignee by acceptance of this Debenture, acknowledge and agree that, by reason
of the provisions of this paragraph, following conversion of a portion of this
Debenture, the unpaid and unconverted principal amount of this Debenture may be
less than the amount stated on the face hereof.

    


    b) Conversion
Price.  The conversion price in effect on any Conversion Date
shall be equal to the lesser of (a) $0.019, subject to adjustment herein (the
“Set Price”)
and (b) 80% of the average of the 3 lowest Closing Prices during the 10 Trading
Days immediately prior to the applicable Conversion Date (subject to adjustment
herein)(the “Conversion
Price”).

    


    c) Conversion
Limitations.  The Company shall not effect any conversion of
this Debenture, and a Holder shall not have the right to convert any portion of
this Debenture, to the extent that after giving effect to the conversion set
forth on the applicable Notice of Conversion, the Holder (together with the
Holder’s Affiliates, and any other person or entity acting as a group together
with the Holder or any of the Holder’s Affiliates) would beneficially own in
excess of the Beneficial Ownership Limitation (as defined below).  For
purposes of the foregoing sentence, the number of shares of Common Stock
beneficially owned by the Holder and its Affiliates shall include the number of
shares of Common Stock issuable upon conversion of this Debenture with respect
to which such determination is being made, but shall exclude the number of
shares of Common Stock which are issuable upon (A) conversion of the remaining,
unconverted principal amount of this Debenture beneficially owned by the Holder
or any of its Affiliates and (B) exercise or conversion of the unexercised or
unconverted portion of any other securities of the Company  subject to
a limitation on conversion or exercise analogous to the limitation contained
herein (including, without limitation, any other Debentures or the Warrants)
beneficially owned by the Holder or any of its Affiliates.  Except as set
forth in the preceding sentence, for purposes of this Section 4(c), beneficial
ownership shall be calculated in accordance with Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder.  To the
extent that the limitation contained in this Section 4(c) applies, the
determination of whether this Debenture is convertible (in relation to other
securities owned by the Holder together with any Affiliates) and of which
principal amount of this Debenture is convertible shall be in the sole
discretion of the Holder, and the submission of a Notice of Conversion shall be
deemed to be the Holder’s determination of whether this Debenture may be
converted (in relation to other securities owned by the Holder together with any
Affiliates) and which principal amount of this Debenture is convertible, in each
case subject to the Beneficial Ownership Limitation. To ensure compliance with
this restriction, the Holder will be deemed to represent to the Company each
time it delivers a Notice of Conversion that such Notice of Conversion has not
violated the restrictions set forth in this paragraph and the Company shall have
no obligation to verify or confirm the accuracy of such
determination.  In addition, a determination as to any group status as
contemplated above shall be determined in accordance with Section 13(d) of the
Exchange Act and the rules and regulations promulgated
thereunder.   For purposes of this Section 4(c), in determining
the number of outstanding shares of Common Stock, the Holder may rely on the
number of outstanding shares of Common Stock as stated in the most recent of the
following: (A) the Company’s most recent periodic or annual report, as the case
may be; (B) a more recent public announcement by the Company; or (C) a more
recent notice by the Company or the Company’s transfer agent setting forth the
number of shares of Common Stock outstanding.  Upon the written or oral
request of a Holder, the Company shall within two Trading Days confirm orally
and in writing to the Holder the number of shares of Common Stock then
outstanding.  In any case, the number of outstanding shares of Common Stock
shall be determined after giving effect to the conversion or exercise of
securities of the Company, including this Debenture, by the Holder or its
Affiliates since the date as of which such number of outstanding shares of
Common Stock was reported. The “Beneficial Ownership
Limitation” shall be 4.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon conversion of this Debenture held by the
Holder.  The Holder, upon not less than 61 days’ prior notice to the
Company, may increase or decrease the Beneficial Ownership Limitation provisions
of this Section 4(c), provided that the Beneficial Ownership Limitation in no
event exceeds 9.99% of the number of shares of the Common Stock outstanding
immediately after giving effect to the issuance of shares of Common Stock upon
conversion of this Debenture held by the Holder and the Beneficial Ownership
Limitation provisions of this Section 4(c) shall continue to
apply.  Any such increase or decrease will not be effective until the
61st
day after such notice is delivered to the Company.  The
Beneficial Ownership Limitation provisions of this paragraph shall be construed
and implemented in a manner otherwise than in strict conformity with the terms
of this Section 4(c) to correct this paragraph (or any portion hereof) which may
be defective or inconsistent with the intended Beneficial Ownership Limitation
contained herein or to make changes or supplements necessary or desirable to
properly give effect to such limitation. The limitations contained in this
paragraph shall apply to a successor holder of this Debenture.

    


    
      	
              d)  

            	
              Mechanics of
      Conversion.

            


    

    


    i. Conversion Shares Issuable
Upon Conversion of Principal Amount.  The number of Conversion
Shares issuable upon a conversion hereunder shall be determined by the quotient
obtained by dividing (x) the outstanding principal amount of this Debenture to
be converted by (y) the Conversion Price.

    i. 

    


    ii. Delivery of Certificate Upon
Conversion. Not later than three Trading Days after each Conversion Date
(the “Share Delivery
Date”), the Company shall deliver, or cause to be delivered, to the
Holder (A) a certificate or certificates representing the Conversion Shares
which, on or after the earlier of (i) the six month anniversary of the Original
Issue Date or (ii) the Effective Date, shall be free of restrictive legends and
trading restrictions (other than those which may then be required by the
Purchase Agreement) representing the number of Conversion Shares being acquired
upon the conversion of this Debenture (including, if the Company has given
continuous notice pursuant to Section 2(b) for payment of interest in shares of
Common Stock at least 20 Trading Days prior to the date on which the Notice of
Conversion is delivered to the Company, shares of Common Stock representing the
payment of accrued interest otherwise determined pursuant to Section 2(a) but
assuming that the Interest Notice Period is the 20 Trading Days period
immediately prior to the date on which the Notice of Conversion is delivered to
the Company and excluding for such issuance the condition that the Company
deliver Interest Conversion Shares as to such interest payment) and (B) a bank
check in the amount of accrued and unpaid interest (if the Company has elected
or is required to pay accrued interest in cash). On or after the earlier of (i)
the six month anniversary of the Original Issue Date or (ii) the Effective Date,
the Company shall use its best efforts to deliver any certificate or
certificates required to be delivered by the Company under this Section 4(d)
electronically through the Depository Trust Company or another established
clearing corporation performing similar functions.

    


    iii. Failure to Deliver
Certificates.  If in the case of any Notice of Conversion such
certificate or certificates are not delivered to or as directed by the
applicable Holder by the third Trading Day after the Conversion Date, the Holder
shall be entitled to elect by written notice to the Company at any time on or
before its receipt of such certificate or certificates, to rescind such
Conversion, in which event the Company shall promptly return to the Holder any
original Debenture delivered to the Company and the Holder shall promptly return
to the Company the Common Stock certificates representing the principal amount
of this Debenture unsuccessfully tendered for conversion to the
Company.

    


    iv. Obligation Absolute; Partial
Liquidated Damages.  The Company’s obligations to issue and
deliver the Conversion Shares upon conversion of this Debenture in accordance
with the terms hereof are absolute and unconditional, irrespective of any action
or inaction by the Holder to enforce the same, any waiver or consent with
respect to any provision hereof, the recovery of any judgment against any Person
or any action to enforce the same, or any setoff, counterclaim, recoupment,
limitation or termination, or any breach or alleged breach by the Holder or any
other Person of any obligation to the Company or any violation or alleged
violation of law by the Holder or any other Person, and irrespective of any
other circumstance which might otherwise limit such obligation of the Company to
the Holder in connection with the issuance of such Conversion Shares; provided, however, that such
delivery shall not operate as a waiver by the Company of any such action the
Company may have against the Holder.  In the event the Holder of this
Debenture shall elect to convert any or all of the outstanding principal amount
hereof, the Company may not refuse conversion based on any claim that the Holder
or anyone associated or affiliated with the Holder has been engaged in any
violation of law, agreement or for any other reason, unless an injunction from a
court, on notice to Holder, restraining and or enjoining conversion of all or
part of this Debenture shall have been sought and obtained, and the Company
posts a surety bond for the benefit of the Holder in the amount of 150% of the
outstanding principal amount of this Debenture, which is subject to the
injunction, which bond shall remain in effect until the completion of
arbitration/litigation of the underlying dispute and the proceeds of which shall
be payable to the Holder to the extent it obtains judgment.  In the
absence of such injunction, the Company shall issue Conversion Shares or, if
applicable, cash, upon a properly noticed conversion.  If the Company
fails for any reason to deliver to the Holder such certificate or certificates
pursuant to Section 4(d)(ii) by the third Trading Day after the Conversion Date,
the Company shall pay to the Holder, in cash, as liquidated damages and not as a
penalty, for each $1,000 of principal amount being converted, $10 per Trading
Day (increasing to $20 per Trading Day on the fifth (5th)
Trading Day after such liquidated damages begin to accrue) for each Trading Day
after such third (3rd)
Trading Day until such certificates are
delivered.    Nothing herein shall limit a Holder’s right to
pursue actual damages or declare an Event of Default pursuant to Section 8
hereof for the Company’s failure to deliver Conversion Shares within the period
specified herein and the Holder shall have the right to pursue all remedies
available to it hereunder, at law or in equity including, without limitation, a
decree of specific performance and/or injunctive relief.  The exercise
of any such rights shall not prohibit the Holder from seeking to enforce damages
pursuant to any other Section hereof or under applicable law.

    


    v. Compensation for Buy-In on
Failure to Timely Deliver Certificates Upon Conversion. In addition to
any other rights available to the Holder, if the Company fails for any reason to
deliver to the Holder such certificate or certificates by the Share Delivery
Date pursuant to Section 4(d)(ii), and if after such Share Delivery Date the
Holder is required by its brokerage firm to purchase (in an open market
transaction or otherwise), or the Holder’s brokerage firm otherwise purchases,
shares of Common Stock to deliver in satisfaction of a sale by the Holder of the
Conversion Shares which the Holder was entitled to receive upon the conversion
relating to such Share Delivery Date (a “Buy-In”), then the
Company shall (A) pay in cash to the Holder (in addition to any other remedies
available to or elected by the Holder) the amount by which (x) the Holder’s
total purchase price (including any brokerage commissions) for the Common Stock
so purchased exceeds (y) the product of (1) the aggregate number of shares of
Common Stock that the Holder was entitled to receive from the conversion at
issue multiplied by (2) the actual sale price at which the sell order giving
rise to such purchase obligation was executed (including any brokerage
commissions) and (B) at the option of the Holder, either reissue (if
surrendered) this Debenture in a principal amount equal to the principal amount
of the attempted conversion or deliver to the Holder the number of shares of
Common Stock that would have been issued if the Company had timely complied with
its delivery requirements under Section 4(d)(ii).  For example, if the
Holder purchases Common Stock having a total purchase price of $11,000 to cover
a Buy-In with respect to an attempted conversion of this Debenture with respect
to which the actual sale price of the Conversion Shares (including any brokerage
commissions) giving rise to such purchase obligation was a total of $10,000
under clause (A) of the immediately preceding sentence, the Company shall be
required to pay the Holder $1,000.  The Holder shall provide the
Company written notice indicating the amounts payable to the Holder in respect
of the Buy-In and, upon request of the Company, evidence of the amount of such
loss.  Nothing herein shall limit a Holder’s right to pursue any other
remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief with
respect to the Company’s failure to timely deliver certificates representing
shares of Common Stock upon conversion of this Debenture as required pursuant to
the terms hereof.

    


    vi. Reservation of Shares
Issuable Upon Conversion. The Company covenants that it will at all times
reserve and keep available out of its authorized and unissued shares of Common
Stock for the sole purpose of issuance upon conversion of this Debenture and
payment of interest on this Debenture, each as herein provided, free from
preemptive rights or any other actual contingent purchase rights of Persons
other than the Holder (and the other holders of the Debentures), not less than
such aggregate number of shares of the Common Stock as shall (subject to the
terms and conditions set forth in the Purchase Agreement) be issuable (taking
into account the adjustments and restrictions of Section 5) upon the conversion
of the outstanding principal amount of this Debenture and payment of interest
hereunder.  The Company covenants that all shares of Common Stock that
shall be so issuable shall, upon issue, be duly authorized, validly issued,
fully paid and nonassessable and, if the Registration Statement is then
effective under the Securities Act, shall be registered for public sale in
accordance with such Registration Statement.

    


    vii. Fractional Shares. No
fractional shares or scrip representing fractional shares shall be issued upon
the conversion of this Debenture.  As to any fraction of a share which
Holder would otherwise be entitled to purchase upon such conversion, the Company
shall at its election, either pay a cash adjustment in respect of such final
fraction in an amount equal to such fraction multiplied by the Conversion Price
or round up to the next whole share.

    


    viii. Transfer
Taxes.  The issuance of certificates for shares of the Common
Stock on conversion of this Debenture shall be made without charge to the Holder
hereof for any documentary stamp or similar taxes that may be payable in respect
of the issue or delivery of such certificates, provided that, the Company shall
not be required to pay any tax that may be payable in respect of any transfer
involved in the issuance and delivery of any such certificate upon conversion in
a name other than that of the Holder of this Debenture so converted and the
Company shall not be required to issue or deliver such certificates unless or
until the person or persons requesting the issuance thereof shall have paid to
the Company the amount of such tax or shall have established to the satisfaction
of the Company that such tax has been paid.

    


    Section
5.                                   Certain
Adjustments.

    


    a) Stock Dividends and Stock
Splits.  If the Company, at any time while this Debenture is
outstanding: (i) pays a stock dividend or otherwise makes a distribution or
distributions payable in shares of Common Stock on shares of Common Stock or any
Common Stock Equivalents (which, for avoidance of doubt, shall not include any
shares of Common Stock issued by the Company upon conversion of, or payment of
interest on, the Debentures), (ii) subdivides outstanding shares of Common Stock
into a larger number of shares, (iii) combines (including by way of a reverse
stock split) outstanding shares of Common Stock into a smaller number of shares
or (iv) issues, in the event of a reclassification of shares of the Common
Stock, any shares of capital stock of the Company, then the Set Price shall be
multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock (excluding any treasury shares of the Company) outstanding
immediately before such event and of which the denominator shall be the number
of shares of Common Stock outstanding immediately after such
event.  Any adjustment made pursuant to this Section shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision,
combination or re-classification.

    


    b) Subsequent Equity
Sales.  If, at any time while this Debenture is
outstanding,  the Company or any Subsidiary, as applicable, sells or
grants any option to purchase or sells or grants any right to reprice, or
otherwise disposes of or issues (or announces any sale, grant or any option to
purchase or other disposition), any Common Stock or Common Stock Equivalents
entitling any Person to acquire shares of Common Stock at an effective price per
share that is lower than the then Set Price (such lower price, the “Base Conversion
Price” and such issuances, collectively, a “Dilutive Issuance”)
(if the holder of the Common Stock or Common Stock Equivalents so issued shall
at any time, whether by operation of purchase price adjustments, reset
provisions, floating conversion, exercise or exchange prices or otherwise, or
due to warrants, options or rights per share which are issued in connection with
such issuance, be entitled to receive shares of Common Stock at an effective
price per share that is lower than the Set Price, such issuance shall be deemed
to have occurred for less than the Set Price on such date of the Dilutive
Issuance), then the Set Price shall be reduced to equal the Base Conversion
Price.  Such adjustment shall be made whenever such Common Stock or
Common Stock Equivalents are issued.  Notwithstanding the foregoing,
no adjustment will be made under this Section 5(b) in respect of an Exempt
Issuance.  If the Company enters into a Variable Rate Transaction,
despite the prohibition set forth in the Purchase Agreement, the Company shall
be deemed to have issued Common Stock or Common Stock Equivalents at the lowest
possible conversion price at which such securities may be converted or
exercised. The Company shall notify the Holder in writing, no later than 1
Business Day following the issuance of any Common Stock or Common Stock
Equivalents subject to this Section 5(b), indicating therein the applicable
issuance price, or applicable reset price, exchange price, conversion price and
other pricing terms (such notice, the “Dilutive Issuance
Notice”).  For purposes of clarification, whether or not the
Company provides a Dilutive Issuance Notice pursuant to this Section 5(b), upon
the occurrence of any Dilutive Issuance, the Holder is entitled to receive a
number of Conversion Shares based upon the Base Conversion Price on or after the
date of such Dilutive Issuance, regardless of whether the Holder accurately
refers to the Base Conversion Price in the Notice of Conversion.

     

    c) Subsequent Rights
Offerings.  If the Company, at any time while the Debenture is
outstanding, shall issue rights, options or warrants to all holders of Common
Stock (and not to Holders) entitling them to subscribe for or purchase shares of
Common Stock at a price per share that is lower than the VWAP on the record date
referenced below, then the Set Price shall be multiplied by a fraction of which
the denominator shall be the number of shares of the Common Stock outstanding on
the date of issuance of such rights or warrants plus the number of additional
shares of Common Stock offered for subscription or purchase, and of which the
numerator shall be the number of shares of the Common Stock outstanding on the
date of issuance of such rights or warrants plus the number of shares which the
aggregate offering price of the total number of shares so offered (assuming
delivery to the Company in full of all consideration payable upon exercise of
such rights, options or warrants) would purchase at such VWAP.  Such
adjustment shall be made whenever such rights or warrants are issued, and shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such rights, options or warrants.

    


    d) Pro Rata
Distributions. If the Company, at any time while this Debenture is
outstanding, distributes to all holders of Common Stock (and not to the Holders)
evidences of its indebtedness or assets (including cash and cash dividends) or
rights or warrants to subscribe for or purchase any security (other than the
Common Stock, which shall be subject to Section 5(b)), then in each such case
the Set Price shall be adjusted by multiplying such Set Price in effect
immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution by a fraction of which the denominator
shall be the VWAP determined as of the record date mentioned above, and of which
the numerator shall be such VWAP on such record date less the then fair market
value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to 1 outstanding share of the Common
Stock as determined by the Board of Directors of the Company in good
faith.  In either case the adjustments shall be described in a
statement delivered to the Holder describing the portion of assets or evidences
of indebtedness so distributed or such subscription rights applicable to 1 share
of Common Stock.  Such adjustment shall be made whenever any such
distribution is made and shall become effective immediately after the record
date mentioned above.

    


    e) Fundamental
Transaction. If, at any time while this Debenture is outstanding, (i) the
Company effects any merger or consolidation of the Company with or into another
Person, (ii) the Company effects any sale of all or substantially all of its
assets in one transaction or a series of related transactions, (iii) any tender
offer or exchange offer (whether by the Company or another Person) is completed
pursuant to which holders of Common Stock are permitted to tender or exchange
their shares for other securities, cash or property, or (iv) the Company effects
any reclassification of the Common Stock or any compulsory share exchange
pursuant to which the Common Stock is effectively converted into or exchanged
for other securities, cash or property (in any such case, a “Fundamental
Transaction”), then, upon any subsequent conversion of this Debenture,
the Holder shall have the right to receive, for each Conversion Share that would
have been issuable upon such conversion immediately prior to the occurrence of
such Fundamental Transaction, the same kind and amount of securities, cash or
property as it would have been entitled to receive upon the occurrence of such
Fundamental Transaction if it had been, immediately prior to such Fundamental
Transaction, the holder of 1 share of Common Stock (the “Alternate
Consideration”).  For purposes of any such conversion, the
determination of the Conversion Price shall be appropriately adjusted to apply
to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of 1 share of Common Stock in such Fundamental Transaction,
and the Company shall apportion the Conversion Price among the Alternate
Consideration in a reasonable manner reflecting the relative value of any
different components of the Alternate Consideration.  If holders of
Common Stock are given any choice as to the securities, cash or property to be
received in a Fundamental Transaction, then the Holder shall be given the same
choice as to the Alternate Consideration it receives upon any conversion of this
Debenture following such Fundamental Transaction.  To the extent
necessary to effectuate the foregoing provisions, any successor to the Company
or surviving entity in such Fundamental Transaction shall issue to the Holder a
new debenture consistent with the foregoing provisions and evidencing the
Holder’s right to convert such debenture into Alternate Consideration. The terms
of any agreement pursuant to which a Fundamental Transaction is effected shall
include terms requiring any such successor or surviving entity to comply with
the provisions of this Section 5(e) and insuring that this Debenture (or any
such replacement security) will be similarly adjusted upon any subsequent
transaction analogous to a Fundamental Transaction.

    


    f) Calculations.  All
calculations under this Section 5 shall be made to the nearest cent or the
nearest 1/100th of a share, as the case may be.  For purposes of this
Section 5, the number of shares of Common Stock deemed to be issued and
outstanding as of a given date shall be the sum of the number of shares of
Common Stock (excluding any treasury shares of the Company) issued and
outstanding.

    


    g) Notice to the
Holder.

    


    i. Adjustment to Set
Price.  Whenever the Conversion Price or Set Price is adjusted
pursuant to any provision of this Section 5, the Company shall promptly deliver
to each Holder a notice setting forth the Conversion Price or Set Price, as
applicable, after such adjustment and setting forth a brief statement of the
facts requiring such adjustment.

    


    ii. Notice to Allow Conversion
by Holder.  If (A) the Company shall declare a dividend (or any
other distribution in whatever form) on the Common Stock, (B) the Company shall
declare a special nonrecurring cash dividend on or a redemption of the Common
Stock, (C) the Company shall authorize the granting to all holders of the Common
Stock of rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any rights, (D) the approval of any stockholders of the
Company shall be required in connection with any reclassification of the Common
Stock, any consolidation or merger to which the Company is a party, any sale or
transfer of all or substantially all of the assets of the Company, of any
compulsory share exchange whereby the Common Stock is converted into other
securities, cash or property or (E) the Company shall authorize the voluntary or
involuntary dissolution, liquidation or winding up of the affairs of the
Company, then, in each case, the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Debenture, and shall
cause to be delivered to the Holder at its last address as it shall appear upon
the Debenture Register, at least twenty (20) calendar days prior to the
applicable record or effective date hereinafter specified, a notice stating (x)
the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be taken,
the date as of which the holders of the Common Stock of record to be entitled to
such dividend, distributions, redemption, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange, provided that the
failure to deliver such notice or any defect therein or in the delivery thereof
shall not affect the validity of the corporate action required to be specified
in such notice.  The Holder is entitled to convert this Debenture
during the 20-day period commencing on the date of such notice through the
effective date of the event triggering such notice.

    


    Section
6.                                   Optional Redemption and
Forced Conversion.

    


    a) Optional Redemption at
Election of Company.  Subject to the provisions of this Section
6(a), at any time after the Original Issue Date, the Company may deliver a
notice to the Holder (an “Optional Redemption
Notice” and the date such notice is deemed delivered hereunder, the
“Optional Redemption
Notice Date”) of its irrevocable election to redeem all of the then
outstanding principal amount of this Debenture for cash in an amount equal to
the Optional Redemption Amount on the 20th Trading
Day following the Optional Redemption Notice Date (such date, the “Optional Redemption
Date”, such 20 Trading Day period, the “Optional Redemption
Period” and such redemption, the “Optional
Redemption”).  The Optional Redemption Amount is payable in
full on the Optional Redemption Date.  The Company covenants and
agrees that it will honor all Notices of Conversion tendered from the time of
delivery of the Optional Redemption Notice through the date all amounts owing
thereon are due and paid in full. The Company’s determination to pay an Optional
Redemption in cash shall be applied ratably to all of the holders of the then
outstanding Debentures based on their (or their predecessor’s) initial purchases
of Debentures pursuant to the Purchase Agreement.

    


    b) Redemption
Procedure.  The payment of cash pursuant to an Optional
Redemption shall be payable on the Optional Redemption Date.  If any
portion of the payment pursuant to an Optional Redemption shall not be paid by
the Company by the applicable due date, interest shall accrue thereon at an
interest rate equal to the lesser of 18% per annum or the maximum rate permitted
by applicable law until such amount is paid in full.  Notwithstanding
anything herein contained to the contrary, if any portion of the Optional
Redemption Amount remains unpaid after such date, the Holder may elect, by
written notice to the Company given at any time thereafter, to invalidate
such Optional Redemption, ab initio, and, with
respect to the Company’s failure to honor the Optional Redemption, the Company
shall have no further right to exercise such Optional
Redemption.  Notwithstanding anything to the contrary in this Section
6, the Company’s determination to redeem in cash under Section 6(a) shall be
applied ratably among the Holders of Debentures. The Holder may elect to convert
the outstanding principal amount of the Debenture pursuant to Section 4 prior to
actual payment in cash for any redemption under this Section 6 by the delivery
of a Notice of Conversion to the Company.

    


    c) Forced Conversion.
Notwithstanding anything herein to the contrary, if after the Effective Date,
the Closing Price for each of any 30 consecutive Trading Days, which period
shall have commenced only after the Effective Date (such period the “Threshold Period”),
exceeds $0.25 (subject to adjustment for reverse and forward stock splits, stock
dividends, stock combinations and other similar transactions of the Common Stock
that occur after the Original Issue Date), the Company may, within 1 Trading Day
after the end of any such Threshold Period, deliver a written notice to the
Holder (a “Forced
Conversion Notice” and the date such notice is delivered to the Holder,
the “Forced Conversion
Notice Date”) to cause the Holder to convert all or part of the then
outstanding principal amount of this Debenture plus, if so specified in the
Forced Conversion Notice, accrued but unpaid interest, liquidated damages and
other amounts owing to the Holder under this Debenture, it being agreed that the
“Conversion Date” for purposes of Section 4 shall be deemed to occur on the
third Trading Day following the Forced Conversion Notice Date (such third
Trading Day, the “Forced Conversion
Date”).  The Company may not deliver a Forced Conversion
Notice, and any Forced Conversion Notice delivered by the Company shall not be
effective, unless all of the Equity Conditions are met (unless waived in writing
by the Holder) on each Trading Day occurring during the applicable Threshold
Period through and including the later of the Forced Conversion Date and the
Trading Day after the date such Conversion Shares pursuant to such conversion
are delivered to the Holder.  Any Forced Conversion shall be applied
ratably to all Holders based on their initial purchases of Debentures pursuant
to the Purchase Agreement, provided that any voluntary conversions by a Holder
shall be applied against the Holder’s pro rata allocation, thereby decreasing
the aggregate amount forcibly converted hereunder if only a portion of this
Debenture is forcibly converted.  For purposes of clarification, a
Forced Conversion shall be subject to all of the provisions of Section 4,
including, without limitation, the provision requiring payment of liquidated
damages and limitations on conversions.

    


    Section
7.                                   Negative Covenants.
As long as any portion of this Debenture remains outstanding, unless the holders
of at least 50% in principal amount of the then outstanding Debentures shall
have otherwise given prior written consent, the Company shall not, and shall not
permit any of its subsidiaries (whether or not a Subsidiary on the Original
Issue Date) to, directly or indirectly:

    


    a) other
than Permitted Indebtedness, enter into, create, incur, assume, guarantee or
suffer to exist any indebtedness for borrowed money of any kind, including, but
not limited to, a guarantee, on or with respect to any of its property or assets
now owned or hereafter acquired or any interest therein or any income or profits
therefrom;

    


    b) other
than Permitted Liens, enter into, create, incur, assume or suffer to exist any
Liens of any kind, on or with respect to any of its property or assets now owned
or hereafter acquired or any interest therein or any income or profits
therefrom;

    


    c) amend its
charter documents, including, without limitation, its certificate of
incorporation and bylaws, in any manner that materially and adversely affects
any rights of the Holder;

    


    d) repay,
repurchase or offer to repay, repurchase or otherwise acquire more than a de minimis number of
shares of its Common Stock or Common Stock Equivalents other than as to (i) the
Conversion Shares or Warrant Shares as permitted or required under the
Transaction Documents and (ii) repurchases of Common Stock or Common Stock
Equivalents of departing officers and directors of the Company, provided that
such repurchases shall not exceed an aggregate of $100,000 for all officers and
directors during the term of this Debenture;

    


    e) repay,
repurchase or offer to repay, repurchase or otherwise acquire any Indebtedness,
other than the Debentures if on a pro-rata basis;

    


    f) pay cash
dividends or distributions on any equity securities of the Company;

    


    g) enter
into any transaction with any Affiliate of the Company which would be required
to be disclosed in any public filing with the Commission, unless such
transaction is made on an arm’s-length basis and expressly approved by a
majority of the disinterested directors of the Company (even if less than a
quorum otherwise required for board approval); or

    


    h) enter
into any agreement with respect to any of the foregoing.

    


    Section
8.                                Events of

Amount, the Holder shall promptly surrender this Debenture to or as directed by

demand, protest or other notice of any kind, and the Holder may immediately and
without expiration of any grace period enforce any and all of its rights and
remedies hereunder and all other remedies available to it under applicable
law.  Such acceleration may be rescinded and annulled by Holder at any
time prior to payment hereunder and the Holder shall have all rights as a holder
of the Debenture until such time, if any, as the Holder receives full payment
pursuant to this Section 8(b).  No such rescission or annulment shall
affect any subsequent Event of Default or impair any right consequent
thereon.

destroyed, but only upon receipt of evidence of such loss, theft or destruction

    d) Governing
Law.  All questions concerning the construction, validity,
enforcement and interpretation of this Debenture shall be governed by and
construed and enforced in accordance with the internal laws of the State of New
York, without regard to the principles of conflict of laws
thereof.  Each party agrees that all legal proceedings concerning the
interpretation, enforcement and defense of the transactions contemplated by any
of the Transaction Documents (whether brought against a party hereto or its
respective Affiliates, directors, officers, shareholders, employees or agents)
shall be commenced in the state and federal courts sitting in the City of New
York, Borough of Manhattan (the “New York
Courts”).  Each party hereto hereby irrevocably submits to the
exclusive jurisdiction of the New York Courts for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated
hereby or discussed herein (including with respect to the enforcement of any of
the Transaction Documents), and hereby irrevocably waives, and agrees not to
assert in any suit, action or proceeding, any claim that it is not personally
subject to the jurisdiction of such New York Courts, or such New York Courts are
improper or inconvenient venue for such proceeding.  Each party hereby
irrevocably waives personal service of process and consents to process being
served in any such suit, action or proceeding by mailing a copy thereof via
registered or certified mail or overnight delivery (with evidence of delivery)
to such party at the address in effect for notices to it under this Debenture
and agrees that such service shall constitute good and sufficient service of
process and notice thereof.  Nothing contained herein shall be deemed
to limit in any way any right to serve process in any other manner permitted by
applicable law. Each party hereto hereby irrevocably waives, to the fullest
extent permitted by applicable law, any and all right to trial by jury in any
legal proceeding arising out of or relating to this Debenture or the
transactions contemplated hereby. If either party shall commence an action or
proceeding to enforce any provisions of this Debenture, then the prevailing
party in such action or proceeding shall be reimbursed by the other party for
its attorneys fees and other costs and expenses incurred in the investigation,
preparation and prosecution of such action or proceeding.

    


    e) Waiver.  Any
waiver by the Company or the Holder of a breach of any provision of this
Debenture shall not operate as or be construed to be a waiver of any other
breach of such provision or of any breach of any other provision of this
Debenture.  The failure of the Company or the Holder to insist upon
strict adherence to any term of this Debenture on one or more occasions shall
not be considered a waiver or deprive that party of the right thereafter to
insist upon strict adherence to that term or any other term of this
Debenture.  Any waiver by the Company or the Holder must be in
writing.

    


    f) Severability.  If
any provision of this Debenture is invalid, illegal or unenforceable, the
balance of this Debenture shall remain in effect, and if any provision is
inapplicable to any Person or circumstance, it shall nevertheless remain
applicable to all other Persons and circumstances.  If it shall be
found that any interest or other amount deemed interest due hereunder violates
the applicable law governing usury, the applicable rate of interest due
hereunder shall automatically be lowered to equal the maximum rate of interest
permitted under applicable law. The Company covenants (to the extent that it may
lawfully do so) that it shall not at any time insist upon, plead, or in any
manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law or other law which would prohibit or forgive the Company from
paying all or any portion of the principal of or interest on this Debenture as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this indenture, and the
Company (to the extent it may lawfully do so) hereby expressly waives all
benefits or advantage of any such law, and covenants that it will not, by resort
to any such law, hinder, delay or impede the execution of any power herein
granted to the Holder, but will suffer and permit the execution of every such as
though no such law has been enacted.

    


    g) Next Business
Day.  Whenever any payment or other obligation hereunder shall
be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day.

    


    h) Headings.  The
headings contained herein are for convenience only, do not constitute a part of
this Debenture and shall not be deemed to limit or affect any of the provisions
hereof.

    


    i) Assumption.  Any
successor to the Company or any surviving entity in a Fundamental Transaction
shall (i) assume, prior to such Fundamental Transaction, all of the obligations
of the Company under this Debenture and the other Transaction Documents pursuant
to written agreements in form and substance satisfactory to the Holder (such
approval not to be unreasonably withheld or delayed) and (ii) issue to the
Holder a new debenture of such successor entity evidenced by a written
instrument substantially similar in form and substance to this Debenture,
including, without limitation, having a principal amount and interest rate equal
to the principal amount and the interest rate of this Debenture and having
similar ranking to this Debenture, which shall be satisfactory to the Holder
(any such approval not to be unreasonably withheld or delayed).  The
provisions of this Section 9(i) shall apply similarly and equally to successive
Fundamental Transactions and shall be applied without regard to any limitations
of this Debenture.

    


    j) Secured
Obligation.  The obligations of the Company under this
Debenture are secured by all assets of the Company and each Subsidiary pursuant
to the Security Agreement, dated as of August 1, 2008 between the Company, the
Subsidiaries of the Company and the Secured Parties (as defined
therein).
