(iii) The Company or any

other facility, indenture agreement, factoring agreement or other instrument under which there may be issued, or by which there
may be secured or evidenced any indebtedness for borrowed money or money due under any long term leasing or factoring arrangement
of the Company or any subsidiary of the Company in an amount exceeding $100,000, whether such indebtedness now exists or shall

    	3



    	 



    


 


(ix) any Event of Default
(as defined in the Other Debentures) occurs with respect to any Other Debentures.


 


(b) During the time
that any portion of this Debenture is outstanding, if any Event of Default has occurred, the full unpaid Principal amount of this
Debenture, together with interest and other amounts owing in respect thereof, to the date of acceleration shall become at the Holder’s
election, immediately due and payable in cash. Furthermore, in addition to any other remedies, the Holder shall have the right
(but not the obligation) to convert this Debenture at any time after (x) an Event of Default or (y) the Maturity Date at the Conversion
Price. The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind,
(other than required notice of conversion) 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be rescinded and annulled by Holder at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent
Event of Default or impair any right consequent thereon.


 


(3) COMPANY REDEMPTION.
The Company at its option shall have the right to redeem (“Optional Redemption”) a portion or all amounts outstanding
under this Debenture prior to the Maturity Date with prior written notice to the Holder. The Company shall pay an amount equal
to the principal amount being redeemed plus a redemption premium equal to 20% of the principal amount being redeemed, plus all
accrued and unpaid Interest, (collectively referred to as the “Redemption Amount”). In order to make a redemption
pursuant to this Section, the Company shall first provide written notice to the Holder of its intention to make a redemption (the
“Redemption Notice”) setting forth the amount of Principal it desires to redeem. After receipt of the Redemption
Notice the Holder shall have three (3) Business Days to elect to convert all or any portion of this Debenture, subject to the limitations
set forth in Section 4(b). On the fourth (4th) Business Day after the Redemption Notice, the Company shall deliver to the Holder
the Redemption Amount with respect to the Principal amount redeemed after giving effect to conversions effected during the three
(3) Business Day period.


 


(4) CONVERSION OF DEBENTURE. This
Debenture shall be convertible into shares of the Company’s Common Stock, on the terms and conditions set forth in this Section
4.


 


(a) Conversion Right.
Subject to the provisions of Section 4(c), at any time or times on or after the Issuance Date, the Holder shall be entitled to
convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and nonassessable shares
of Common Stock in accordance with Section 4(b), at the Conversion Rate (as defined below). The number of shares of Common Stock
issuable upon conversion of any Conversion Amount pursuant to this Section 4(a) shall be determined by dividing (x) such Conversion
Amount by (y) the Conversion Price (the “Conversion Rate”). The Company shall not issue any fraction of a share
of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the
Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer,
stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion
Amount.


 




    	4



    	 



    


 


(i) “Conversion
Amount” means the portion of the Principal and accrued Interest to be converted, redeemed or otherwise with respect to
which this determination is being made.


 


(ii) “Conversion
Price” means, as of any Conversion Date (as defined below) or other date of determination, the lesser of (a) $15 (the
“Fixed Conversion Price”), or (b) 90% of the lowest daily VWAP during the 10 consecutive Trading Days immediately
preceding the Conversion Date or other date of determination (the “Market Conversion Price”). The Conversion
Price shall be adjusted from time to time pursuant to the other terms and conditions of this Debenture. For the avoidance of doubt,
the Fixed Conversion Price is set after taking into account the consolidations that took effect in December, 2012.


 


(b) Mechanics of
Conversion.


 


(i) Optional Conversion.
To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”), the Holder shall
(A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of
an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”) to
the Company and (B) if required by Section 4(b)(iv), surrender this Debenture to a nationally recognized overnight delivery service
for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Debenture
in the case of its loss, theft or destruction). On or before the third Business Day following the date of receipt of a Conversion
Notice (the “Share Delivery Date”), the Company shall (X) if legends are not required to be placed on certificates
of Common Stock and provided that the Transfer Agent is participating in the Depository Trust Company’s (“DTC”)
Fast Automated Securities Transfer Program, credit such aggregate number of shares of Common Stock to which the Holder shall be
entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission
system or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver
to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for
the number of shares of Common Stock to which the Holder shall be entitled which certificates shall not bear any restrictive legends
unless required pursuant to rules and regulations of the Commission. If this Debenture is physically surrendered for conversion
and the outstanding Principal of this Debenture is greater than the Principal portion of the Conversion Amount being converted,
then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Debenture
and at its own expense, issue and deliver to the holder a new Debenture representing the outstanding Principal not converted. The
Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Debenture shall be treated
for all purposes as the record holder or holders of such shares of Common Stock upon the transmission of a Conversion Notice.


 


(ii) Company’s
Failure to Timely Convert. If within three (3) Trading Days after the Company’s receipt of the facsimile copy of a Conversion
Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder’s balance account with
DTC for the number of shares of Common Stock to which the Holder is entitled upon such holder’s conversion of any Conversion
Amount (a “Conversion Failure”), and if on or after such Trading Day the Holder purchases (in an open market
transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion
that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3)
Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount
equal to the Holder’s total purchase price (including brokerage commissions and other out of pocket expenses, if any) for
the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s
obligation to deliver such certificate (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation
to deliver to the Holder a certificate or certificates representing such Common Stock and pay cash to the Holder in an amount equal
to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing
Bid Price on the Conversion Date.


 




    	5



    	 



    


 


(iii) Book-Entry.
Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Debenture in accordance with
the terms hereof, the Holder shall not be required to physically surrender this Debenture to the Company unless (A) the full Conversion
Amount represented by this Debenture is being converted or (B) the Holder has provided the Company with prior written notice (which
notice may be included in a Conversion Notice) requesting reissuance of this Debenture upon physical surrender of this Debenture.
The Holder and the Company shall maintain records showing the Principal and Interest converted and the dates of such conversions
or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender
of this Debenture upon conversion.


 


(c) Limitations on Conversions.


 


(i) Beneficial Ownership.
The Company shall not effect any conversions of this Debenture and the Holder shall not have the right to convert any portion of
this Debenture or receive shares of Common Stock as payment of interest hereunder to the extent that after giving effect to such
conversion or receipt of such interest payment, the Holder, together with any affiliate thereof, would beneficially own (as determined
in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the number of
shares of Common Stock outstanding immediately after giving effect to such conversion or receipt of shares as payment of interest.
Since the Holder will not be obligated to report to the Company the number of shares of Common Stock it may hold at the time of
a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of 4.99%
of the then outstanding shares of Common Stock without regard to any other shares which may be beneficially owned by the Holder
or an affiliate thereof, the Holder shall have the authority and obligation to determine whether the restriction contained in this
Section will limit any particular conversion hereunder and to the extent that the Holder determines that the limitation contained
in this Section applies, the determination of which portion of the principal amount of this Debenture is convertible shall be the
responsibility and obligation of the Holder. If the Holder has delivered a Conversion Notice for a principal amount of this Debenture
that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in
excess of the permitted amount hereunder, the Company shall notify the Holder of this fact and shall honor the conversion for the
maximum principal amount permitted to be converted on such Conversion Date in accordance with Section 4(a) and, any principal amount
tendered for conversion in excess of the permitted amount hereunder shall remain outstanding under this Debenture. The provisions
of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than 65 days prior
notice to the Company. Other Holders shall be unaffected by any such waiver.

(d) Other Provisions.


 


(i) The Company shall
at all times reserve and keep available out of its authorized Common Stock the full number of shares of Common Stock issuable upon
conversion of all outstanding amounts under this Debenture; and within three (3) Business Days following the receipt by the Company
of a Holder’s notice that such minimum number of Underlying Shares is not so reserved, the Company shall promptly reserve
a sufficient number of shares of Common Stock to comply with such requirement.


 


(ii) All calculations
under this Section 4 shall be rounded to the nearest $0.0001 or whole share.


 


(iii) 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 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, not less than such number of shares of
the Common Stock as shall be issuable (taking into account the adjustments and restrictions set forth herein) 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 and validly authorized, issued and fully paid, nonassessable
and, if the Underlying Shares Registration Statement has been declared effective under the Securities Act, registered for public
sale in accordance with such Underlying Shares Registration Statement.


 


(iv) Nothing herein shall
limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 2 herein for the Company
’s failure to deliver certificates representing shares of Common Stock upon conversion within the period specified herein
and such 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, in each case without the need to post a bond or provide other security.
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.


 


(5) Adjustments to Conversion Price


 


(a) Adjustment of
Conversion Price upon Issuance of Common Stock. If the Company, at any time while this Debenture is outstanding, issues or
sells, or in accordance with this Section 5(a) is deemed to have issued or sold, any shares of Common Stock, excluding shares of
Common Stock deemed to have been issued or sold by the Company in connection with any Excluded Securities, for a consideration
per share (the “New Issuance Price”) less than a price equal to the Fixed Conversion Price in effect immediately
prior to such issue or sale (such price the “Applicable Price”) (the foregoing a “Dilutive Issuance”),
then immediately after such Dilutive Issuance the Fixed Conversion Price then in effect shall be reduced to an amount equal to
the New Issuance Price. For purposes of determining the adjusted Fixed Conversion Price under this Section 5(a), the following
shall be applicable:


 




    	7



    	 



    


 


(i) Issuance of Options.
If the Company in any manner grants or sells any Options and the lowest price per share for which one share of Common Stock is
issuable upon the exercise of any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable
upon exercise of such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding
and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For
purposes of this Section, the “lowest price per share for which one share of Common Stock is issuable upon the exercise of
any such Option or upon conversion or exchange or exercise of any Convertible Securities issuable upon exercise of such Option”
shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to
any one share of Common Stock upon granting or sale of the Option, upon exercise of the Option and upon conversion or exchange
or exercise of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Conversion Price shall
be made upon the actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such Options
or upon the actual issuance of such Common Stock upon conversion or exchange or exercise of such Convertible Securities.


 


(ii) Issuance of Convertible
Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per share for which
one share of Common Stock is issuable upon such conversion or exchange or exercise thereof is less than the Applicable Price, then
such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the
issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section, the “lowest price
per share for which one share of Common Stock is issuable upon such conversion or exchange or exercise” shall be equal to
the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of
Common Stock upon the issuance or sale of the Convertible Security and upon the conversion or exchange or exercise of such Convertible
Security. No further adjustment of the Conversion Price shall be made upon the actual issuance of such share of Common Stock upon
conversion or exchange or exercise of such Convertible Securities, and if any such issue or sale of such Convertible Securities
is made upon exercise of any Options for which adjustment of the Conversion Price had been or are to be made pursuant to other
provisions of this Section, no further adjustment of the Conversion Price shall be made by reason of such issue or sale.


 


(iii) Change in Option
Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable
upon the issue, conversion, exchange or exercise of any Convertible Securities, or the rate at which any Convertible Securities
are convertible into or exchangeable or exercisable for Common Stock changes at any time, the Conversion Price in effect at the
time of such change shall be adjusted to the Conversion Price which would have been in effect at such time had such Options or
Convertible Securities provided for such changed purchase price, additional consideration or changed conversion rate, as the case
may be, at the time initially granted, issued or sold. For purposes of this Section, if the terms of any Option or Convertible
Security that was outstanding as of the Issuance Date are changed in the manner described in the immediately preceding sentence,
then such Option or Convertible Security and the Common Stock deemed issuable upon exercise, conversion or exchange thereof shall
be deemed to have been issued as of the date of such change. No adjustment shall be made if such adjustment would result in an
increase of the Conversion Price then in effect.


 




    	8



    	 



    


 


(iv) Calculation of
Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company,
together comprising one integrated transaction in which no specific consideration is allocated to such Options by the parties thereto,
the Options will be deemed to have been issued for the difference of (x) the aggregate fair market value of such Options and other
securities issued or sold in such integrated transaction, less (y) the fair market value of the securities other than such Option,
issued or sold in such transaction and the other securities issued or sold in such integrated transaction will be deemed to have
been issued or sold for the balance of the consideration received by the Company. If any Common Stock, Options or Convertible Securities
are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the
gross amount raised by the Company; provided, however, that such gross amount is not greater than 110% of the net amount received
by the Company therefor. If any Common Stock, Options or Convertible Securities are issued or sold for a consideration other than
cash, the amount of the consideration other than cash received by the Company will be the fair value of such consideration, except
where such consideration consists of securities, in which case the amount of consideration received by the Company will be the
Closing Bid Price of such securities on the date of receipt. If any Common Stock, Options or Convertible Securities are issued
to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving entity, the amount
of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving
entity as is attributable to such Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration
other than cash or securities will be determined jointly by the Company and the Holder. If such parties are unable to reach agreement
within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair
value of such consideration will be determined within five (5) Business Days after the tenth (10th) day following the
Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder. The determination of such
appraiser shall be deemed binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne
by the Company.


 


(v) Record Date.
If the Company takes a record of the holders of Common Stock for the purpose of entitling them (A) to receive a dividend or other
distribution payable in Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase Common Stock, Options
or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the Common Stock deemed
to have been issued or sold upon the declaration of such dividend or the making of such other distribution or the date of the granting
of such right of subscription or purchase, as the case may be.


 




    	9



    	 



    


 


(b) Adjustment of
Conversion Price upon Subdivision or Combination of Common Stock. If the Company, at any time while this Debenture is outstanding,
shall (a) pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other
equity or equity equivalent securities payable in shares of Common Stock, (b) subdivide outstanding shares of Common Stock into
a larger number of shares, (c) combine (including by way of reverse stock split) outstanding shares of Common Stock into a smaller
number of shares, or (d) issue 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 before such event and of which the denominator shall be the number of shares of Common Stock
outstanding 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.


 


(c) Purchase Rights.
If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities
or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then
the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which
the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete conversion
of this Debenture (without taking into account any limitations or restrictions on the convertibility of this Debenture) immediately
before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken,
the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.


 


(d) Other Events.
If any event occurs of the type contemplated by the provisions of this Section 4 but not expressly provided for by such provisions
(including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features),
then the Company’s Board of Directors will make an appropriate adjustment in the Conversion Price so as to protect the rights
of the Holder under this Debenture; provided that no such adjustment will increase the Conversion Price as otherwise determined
pursuant to this Section 5.


 


(e) Other Corporate
Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental
Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect
to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision
to insure that the Holder will thereafter have the right to receive upon a conversion of this Debenture, at the Holder’s
option, (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which
the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the
Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility
of this Debenture) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or
other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such
amounts as the Holder would have been entitled to receive had this Debenture initially been issued with conversion rights for the
form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with
the Conversion Rate. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required
Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without
regard to any limitations on the conversion or redemption of this Debenture.


 




    	10



    	 



    


 


(f) Whenever the Conversion
Price is adjusted pursuant to Section 5 hereof, the Company shall promptly mail to the Holder a notice setting forth the Conversion
