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 into shares of Common Stock at the option of the Holder, in whole or in part at any time and from time to time (subject
to the limitations on conversion set forth in Section 4(c) hereof).  The Holder shall effect conversions by delivering
to the Company the form of Notice of Conversion attached hereto as Annex A (a “Notice of Conversion”),
specifying therein the principal amount of this Debenture to be converted and the date on which such conversion is to be effected
(a “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 provided 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 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
converted and the date of such conversions.  The Company shall deliver any objection to any Notice of Conversion within 1
Business Day of receipt of such notice.  In the event of any dispute or discrepancy, the records of the Holder shall be controlling

b)       Conversion
Price.  The conversion price in effect on any Conversion Date shall be equal to 80% of the VWAP of the 10 consecutive
Trading Days prior to the Conversion Date (subject to adjustment herein) (the “Conversion Price”).       


 




    	6



    	 



    

c)       Holder’s
Restriction on Conversion.  The Company shall not effect any conversion of this Debenture, and the 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 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 Form 10-Q or Form 10-K,
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 the 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 Beneficial Ownership Limitation provisions
of this Section 4(c) may be waived by the Holder, at the election of the Holder, upon not less than 61 days’ prior notice
to the Company, to change the Beneficial Ownership Limitation to 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 provisions of this Section 4(c) shall continue to apply.  Upon such a change by the Holder of the Beneficial Ownership
Limitation from such 4.99% limitation to such 9.99% limitation, the Beneficial Ownership Limitation may not be further waived by
the Holder.  The 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 herein contained 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.       


 




    	7



    	 



    

d)              Mechanics
of Conversion       


 


i.       Conversion
Shares Issuable Upon Conversion of Principal Amount.  The number of shares of Common Stock 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.       


 


ii.       Delivery
of Certificate Upon Conversion. Not later than three Trading Days after any Conversion Date, the Company will deliver or cause
to be delivered to the Holder a certificate or certificates representing the Conversion Shares which shall be free of restrictive
legends and trading restrictions representing the number of shares of Common Stock being acquired upon the conversion of this Debenture.
The Company shall, if available and if allowed under applicable securities laws, use its best efforts to deliver any certificate
or certificates required to be delivered by the Company under this Section electronically through the Depository Trust Corporation
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 a Conversion Date, the Holder shall be entitled by written
notice to the Company at any time on or before its receipt of such certificate or certificates thereafter, to rescind such conversion,
in which event the Company shall immediately return the certificates representing the principal amount of this Debenture tendered
for conversion.       


 


iv.       Obligation
Absolute; Partial Liquidated Damages.  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 $1000 of principal amount being converted, $10 per Trading Day (increasing
to $20 per Trading Day after 5 Trading Days after such damages begin to accrue) for each Trading Day after such third Trading Day
until such certificates are delivered.  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, 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, 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 principal amount of this Debenture outstanding, which is subject to the injunction, which bond
shall remain in effect until the completion of arbitration/litigation of the dispute and the proceeds of which shall be payable
to the Holder to the extent it obtains judgment.  In the absence of an injunction precluding the same, the Company shall issue
Conversion Shares or, if applicable, cash, upon a properly noticed conversion.  Nothing herein shall limit the Holder’s
right to pursue actual damages or declare an Event of Default pursuant to Section 8 herein 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
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 pursuant to Section 4(d)(ii) by the
third Trading Day after the Conversion Date, and if after such third Trading Day the Holder is required by its brokerage firm to
purchase (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of the Conversion
Shares which the Holder anticipated receiving upon such conversion (a “Buy-In”), then the Company shall (A)
pay in cash to the Holder (in addition to any remedies available to or elected by the Holder) the amount by which (x) the Holder’s
total purchase price (including brokerage commissions, if any) for the Common Stock so purchased exceeds (y) the product of (1)
the aggregate number of shares of Common Stock that the Holder anticipated receiving from the conversion at issue multiplied by
(2) the actual sale price of the Common Stock at the time of the sale (including brokerage commissions, if any) giving rise to
such purchase obligation 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 had the Company 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 at the time of the sale (including brokerage
commissions, if any) 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.  Notwithstanding anything contained herein to the contrary, if
the Holder requires the Company to make payment in respect of a Buy-In for the failure to timely deliver certificates hereunder
and the Company timely pays in full such payment, the Company shall not be required to pay the Holder liquidated damages under
Section 4(d)(iv) in respect of the certificates resulting in such Buy-In.       


 


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 solely for the purpose of issuance upon conversion of this Debenture, 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 number of shares of the Common Stock as shall be issuable (taking into account the adjustments
and restrictions of Section 5) upon the conversion of the outstanding principal amount of this Debenture.  The Company covenants
that all shares of Common Stock that shall be so issuable shall, upon issue, be duly and validly authorized, issued and fully paid,
nonassessable and registered for public sale.       


 




    	9



    	 



    

vii.       Fractional
Shares. Upon a conversion hereunder the Company shall not be required to issue stock certificates representing fractions of
shares of the Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based
on the Closing Price at such time.  If the Company elects not, or is unable, to make such a cash payment, the Holder shall
be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock.       


 


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 certificate, 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: (A) pays a stock dividend
or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities
payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company
pursuant to this Debenture), (B) subdivides outstanding shares of Common Stock into a larger number of shares, (C) combines (including
by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (D) issues by reclassification
of shares of the Common Stock any shares of capital stock of the Company, then the Conversion Price shall be multiplied by a fraction
of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) 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
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 Conversion 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.       


 




    	10



    	 



    

c)       Pro
Rata Distributions. If the Company, at any time while this Debenture is outstanding, shall distribute to all holders of Common
Stock (and not to the holders of the Debenture) evidences of its indebtedness or assets (including cash and cash dividends) or
rights or warrants to subscribe for or purchase any security, then in each such case the Conversion Price shall be adjusted by
multiplying such Conversion 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 Closing Price determined as of the record date
mentioned above, and of which the numerator shall be such Closing Price 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 one outstanding share of
the Common Stock as determined by the Board of Directors in good faith.  In either case the adjustments shall be described
in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription
rights applicable to one 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.       


 


d)       Fundamental
Transaction. If, at any time while this Debenture is outstanding, (A) the Company effects any merger or consolidation of the
Company with or into another Person, (B) the Company effects any sale of all or substantially all of its assets in one or a series
of related transactions, (C) 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 (D)
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 one 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 one 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 paragraph (d) and insuring that this Debenture (or any such replacement security) will be similarly adjusted
upon any subsequent transaction analogous to a Fundamental Transaction.       


 




    	11



    	 



    

e)       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 treasury shares, if any) issued and outstanding.       


 


f)       Notice
to the Holder.       


 


i.       Adjustment
to Conversion Price.  Whenever the Conversion Price is adjusted pursuant to any of this Section 5, the Company shall promptly
mail to each Holder a notice setting forth the Conversion Price 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) 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 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; (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 mailed to the Holder at its last addresses as it shall appear
upon the  stock books of the Company, at least 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 mail such notice or any defect therein or in the mailing 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 the date of such notice to the effective date of the event triggering such notice.       


 


Section 6.       Redemption.       


 


a)       Optional
Redemption at Election of Company.  Subject to the provisions of this Section 6 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 some or all of the then outstanding Debentures, for an
amount, in cash, equal to the Optional Redemption Amount on the 10th Trading Day following the Optional Redemption Notice Date
(such date, the “Optional Redemption Date” and such redemption, the “Optional Redemption”). 
The Optional Redemption Amount is due in full on the Optional Redemption Date.  The Company may only effect an Optional Redemption
if during the period commencing on the Optional Redemption Notice Date through to the Optional Redemption Date and through and
including the date such Optional Redemption Amount is paid to the Holder, each of the Equity Conditions shall have been met. 
If any of the Equity Conditions shall cease to be satisfied at any time during the required period, then the Holder may elect to
nullify the Optional Redemption Notice by notice to the Company within 3 Trading Days after the first day, the Holder has received
proper notice from the Company that any such Equity Condition has not been met in which case the Optional Redemption Notice shall
be null and void, ab initio.  The Company covenants and agrees that it will honor all Notices of Conversions
tendered from the time of delivery of the Optional Redemption Notice through the date all amounts owing thereon are due and paid
in full.       


 




    	12



    	 



    

b)       Quarterly
Redemption.       


 


i.       On
each Quarterly Redemption Date, the Company shall redeem the Quarterly Redemption Amount, the sum of all liquidated damages and
any other amounts then owing to the Holder in respect of this Debenture (the “Quarterly Redemption”). The Quarterly
Redemption Amount due on each Quarterly Redemption Date shall be paid in cash; provided, however, as to any Quarterly
Redemption and upon 20 Trading Days’ prior written irrevocable notice (the “Quarterly Redemption Notice”
and the 20 Trading Day period immediately following the Quarterly Redemption Notice, the “Quarterly Redemption Period”),
in lieu of a cash redemption payment the Company may elect to pay all or part of a Quarterly Redemption Amount in Conversion Shares
(such dollar amount to be paid on a Quarterly Redemption Date in Conversion Shares, the “Quarterly Redemption Share Amount”)
based on a conversion price equal to the lesser of (i) the then Conversion Price (for the period ending on or prior to the Quarterly
Redemption Date) and (ii) 80% of the average of the 10 closing prices immediately prior to the applicable Quarterly Redemption
Date (subject to adjustment for any stock dividend, stock split, stock combination or other similar event affecting the Common
Stock during such 10 Trading Day period) (the price calculated during the 10 Trading Day period immediately prior to the Quarterly
Redemption Date, the “Quarterly Conversion Price” and such period, the “Quarterly Conversion Period”);
provided, further, that the Company may not pay the Quarterly Redemption Amount in Conversion Shares unless, (y)
from the date the Holder receives the duly delivered Quarterly Redemption Notice through and until the date such Quarterly Redemption
is paid in full, the Equity Conditions, unless waived in writing by the Holder, have been satisfied and (z) as to such Quarterly
Redemption, prior to such Quarterly Redemption Period (but not more than 5 Trading Days prior to the commencement of the Quarterly
Redemption 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 Quarterly Redemption Share Amount equal to the quotient of (x) the applicable
Quarterly Redemption Share Amount divided by (y) the lesser of (1) the then Conversion Price and (2) the Quarterly Conversion Price
assuming for such purposes that the Quarterly Conversion Period ends 5 Trading Days prior to the actual Quarterly Redemption Period 
(the “Pre-Redemption Conversion Shares”).  The Holder may convert, pursuant to Section 4(a), any principal
amount of this Debenture subject to a Quarterly Redemption at any time prior to the date that the Quarterly Redemption Amount and
all amounts owing thereon are due and paid in full.  Any principal amount of this Debenture converted during the applicable
Quarterly Redemption Period until the date the Quarterly Redemption Amount is paid in full shall be applied to the principal amount
subject to the Quarterly Redemption Amount payable in cash and then to the Quarterly Redemption Share Amount.  Any principal
amount of this Debenture converted during the applicable Quarterly Redemption Period in excess of the Quarterly Redemption Amount
shall be applied against the last principal amount of this Debenture scheduled to be redeemed hereunder, in reverse time order
from the Maturity Date; provided, however, if any such conversion is applied to such Quarterly Redemption Amount,
the Pre-Redemption Conversion Shares, if any were issued in connection with such Quarterly Redemption or were not already applied
to such conversions, shall be first applied against such conversion.  The Company covenants and agrees that it will honor
all Notice of Conversions tendered up until such amounts are paid in full.         


 


        


 




    	13



    	 



    

       


 


ii.       Notwithstanding
anything to the contrary in Section 6(b)(i), the Holder shall have the right to defer up to 3 Quarterly Redemptions in any 12 month
period until a future date determined at the Holder’s sole discretion (each a “Deferred Redemption”).
Such Deferred Redemption shall be payable pursuant to the procedures for payment under a Quarterly Redemption in Section 6(b)(i)
on the Deferred Redemption Date. The Holder may convert, pursuant to Section 4(a), any principal amount of this Debenture subject
to a Deferred Redemption at any time prior to the date that the Deferred Redemption Amount and all amounts owing thereon are due
and paid in full.  Any principal amount of this Debenture converted during a Deferred Redemption Period until the date the
Deferred Redemption Amount is paid in full shall be applied to the principal amount subject to the Deferred Redemption Amount payable
in cash.  Any principal amount of this Debenture converted during the applicable Deferred Redemption Period in excess of the
Deferred Redemption Amount shall be applied against the last principal amount of this Debenture scheduled to be redeemed hereunder,
in reverse time order from the Maturity Date.  The Company covenants and agrees that it will honor all Notice of Conversions
tendered up until such amounts are paid in full.  At any time a Holder delivers a Deferred Redemption Notice, the Company
shall, if required, file a prospectus supplement pursuant to Rule 424 disclosing such election.       


  


c)       Mandatory
Redemption. The Company shall be required to redeem the Debentures at 100% of the principal amount thereof plus accrued interest
to the date of redemption with 25% of the net cash proceeds received by the Company from the sale of Financing Debt. Such redemption
shall be on the date of closing of the sale of the Financing Debt.      


 


d)       Redemption
Procedure.  The payment of cash pursuant to the Quarterly Redemption, an Optional Redemption or a Deferred Redemption,
shall be made on the Quarterly Redemption Date, the Optional Redemption Date or the Deferred Redemption Date, as applicable. 
If any portion of the cash payment for a Quarterly Redemption, an Optional Redemption or a Deferred Redemption, as applicable shall
not be paid by the Company by the respective due date, interest shall accrue thereon at the rate of 18% per annum (or the maximum
rate permitted by applicable law, whichever is less) until the payment of the Quarterly Redemption Amount, the Optional Redemption
Amount or the Deferred Redemption Amount, as applicable, plus all amounts owing thereon is paid in full.  Alternatively, if
any portion of the Quarterly Redemption Amount, the Optional Redemption Amount or the Deferred Redemption Amount, as applicable,
remains unpaid after such date, the Holder may elect, by written notice to the Company given at any time thereafter, to invalidate
ab initio such redemption, notwithstanding anything herein contained to the contrary, and, with respect the failure
to honor the Optional Redemption as applicable, the Company shall have no further right to exercise such Optional Redemption. 
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 fax or email delivery of a Notice of Conversion to the Company.

c)       amend
its certificate of incorporation, bylaws or other charter documents (the “Charter Documents”) so as to materially

the prior written consent of the Holder (i) in connection with a merger transaction or reorganization or (ii) to change the authorized
number of capital stock in connection with a financing transaction, a recapitalization, stock-split, reverse stock-split or similar
transaction;       


 


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;       


 


e)       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);       


 


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


 


g)       transfer,
pledge, hypothecate, encumber, license, sell or otherwise dispose of any of the Collateral (except for sales, licenses, and dispositions
granted or made by the Company or its Subsidiaries in its ordinary course of business); or       


 


h)       enter
into any agreement with respect to any of the foregoing; provided, that the Company shall be entitled to agree to any of the actions
otherwise prohibited by Section 7(g) in connection with any sale of the Company or substantially all of its assets, or a merger
or consolidation or other Change of Control Transaction so long as it otherwise complies with the terms of this Debenture applicable
to any such transaction or, in the case of any such transaction which results in an Event of Default, so long as the Debenture
is paid in full in accordance with the terms of the Debenture prior to or simultaneously with the consummation of such transaction.

vi.       the
Company or any Subsidiary shall default in any of its obligations under any mortgage, credit agreement or other facility, indenture
agreement, factoring agreement or other instrument under which there may be issued, or by which there may be secured or evidenced

b)       Remedies
Upon Event of Default. If any Event of Default occurs, the full principal amount of this Debenture, together with other amounts
owing in respect thereof, to the date of acceleration shall become, at the Holder’s election, immediately due and payable
in cash.   The aggregate amount payable upon an Event of Default shall be equal to the Mandatory Default Amount. 
Commencing 5 days after the occurrence of any Event of Default that results in the eventual acceleration of this Debenture, the
interest rate on this Debenture shall accrue at the rate of 18% per annum, or such lower maximum amount of interest permitted to
be charged under applicable law.  Upon the payment in full of the Mandatory Default Amount on this entire Debenture the Holder
shall promptly surrender this Debenture to or as directed by the Company.  The Holder need not provide and the Company hereby
waives any presentment, 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 declaration may be rescinded and annulled by Holder at any time prior to payment hereunder and the Holder shall have all rights
as a Debenture holder until such time, if any, as the full payment under this Section shall have been received by it.  No
such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

Company, which is absolute and unconditional, to pay the principal of, and liquidated damages (if any) on, this Debenture at the
time, place, and rate, and in the coin or currency, herein prescribed.  This Debenture is a direct debt obligation of the
Company.  This Debenture ranks pari passu with all other Debentures now or hereafter issued under the terms
set forth herein.       


 


c)       Lost
or Mutilated Debenture.  If this Debenture shall be mutilated, lost, stolen or destroyed, the Company shall execute and
deliver, in exchange and substitution for and upon cancellation of a mutilated Debenture, or in lieu of or in substitution for

destroyed but only upon receipt of evidence of such loss, theft or destruction of such Debenture, and of the ownership hereof,
and indemnity, if requested, all reasonably satisfactory to the Company.       


 


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
conflicts of law thereof.  Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense
of the transactions contemplated hereby (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, 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 any such court, 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 manner permitted by law. Each party hereto hereby irrevocably waives, to the fullest extent permitted

and Waivers.  This Debenture, or any provisions hereof, may be modified or amended or the provisions hereof waived with
the prior written consent of the Company and the Holder.  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.

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 applicable
laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted
rate of interest. 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 impeded 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 surviving entity in a Fundamental Transaction shall (i) assume in writing all of the obligations
of the Company under this Debenture, the Settlement Agreement and the Security Agreement pursuant to written agreements in form
and substance satisfactory to the Holder (such approval not to be unreasonably withheld or delayed) prior to such Fundamental Transaction
and (ii) to 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 amounts and the interest rates of the Debentures held by the Holder and having similar ranking to this Debenture, and
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)       The
Company shall at all times keep in full force and effect their respective valid existence and good standing and any rights and
franchises material to its businesses.
