principal amount of this Debenture at the rate of 16% per annum, payable quarterly on February 1, May 1, August 1 and November

    	7



    	 



    

 


b)         Company’s
Election to Pay Interest in Cash or Kind. 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. 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(c)(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(c)(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.


 




    	8



    	 



    

 


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(d) 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. No ink-original Notice of Conversion shall
be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be
required. 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 one (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 $5.24, subject to adjustment herein
(the “Conversion Price”).


 


c)         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.

ii.         Delivery

the Conversion Shares which, on or after the six month anniversary of the Original Issue 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 prior to the commencement of the Interest Notice Period), (B) a legal opinion

with its prime broker (or other brokerage account), together with the instruction letter to the Transfer Agent and the resolution
of the Board of Directors authorizing the Transaction Documents and any additional supporting documentation requested by the Holder
(including, without limitation, any instruction letter to the Company’s transfer agent) and (C) a bank check in the amount
of any accrued and unpaid interest that may be due thereon (if the Company has elected or is required to pay accrued interest in
cash). On or after the six month anniversary of the Original Issue Date, if the Company is a participant in the Deposit or Withdrawal
at Custodian system (DWAC) of the Depository Trust Company, the Company
shall use deliver any certificate or certificates required to be delivered by the Company under this Section 4(c) 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 and the related legal
opinion of Company counsel, the instruction letter to the Transfer Agent and the resolution of the Board of Directors authorizing
the Transaction Documents are not delivered to or as directed by the applicable Holder by the Share Delivery 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 issued to such Holder pursuant to
the rescinded Conversion Notice.

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 and the related legal opinion of Company counsel, the instruction letter to the Transfer Agent
and the resolution of the Board of Directors authorizing the Transaction Documents and other supporting documentation pursuant
to Section 4(c)(ii) by the Share Delivery 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 Share Delivery Date
until such certificates and related legal opinion of Company counsel, the instruction letter to the Transfer Agent, the resolution
of the Board of Directors authorizing the Transaction Documents and other supporting documentation are delivered or Holder rescinds
such conversion. 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(c)(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, if any, 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 (in which case such conversion shall be deemed rescinded) 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(c)(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 any adjustments
and restrictions of Section 5) upon the conversion of the then 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.


 


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 the 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.


 




    	13



    	 



    

 


viii.         Transfer
Taxes and Expenses. 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. The Company shall pay all Transfer Agent fees required for same-day processing of any
Notice of Conversion.


 




    	14



    	 



    

 


d)         Holder’s
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 Persons 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 (i) conversion
of the remaining, unconverted principal amount of this Debenture beneficially owned by the Holder or any of its Affiliates and
(ii) 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(d), 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(d) 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(d), 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: (i) the Company’s most recent
periodic or annual report filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company,
or (iii) a more recent written 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(d), 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(d) 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(d)
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.


 


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 Conversion
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.


 






    	15



    	 



    

 


b)         [RESERVED]


 


c)         Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 5(a) above, if at any time
the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property
pro rata to the record holders of any class of shares 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 regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) 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 shares of Common Stock are to be determined for the grant, issue or sale of such Purchase
Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in
the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase
Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent)
and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto
would not result in the Holder exceeding the Beneficial Ownership Limitation).


 


d)         Pro
Rata Distributions. During such time as this Debenture is outstanding, if the Company shall declare or make any dividend or
other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital
or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of
a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a "Distribution"),
at any time after the issuance of this Debenture, then, in each such case, the Holder shall be entitled to participate in such
Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of
Common Stock acquirable upon complete exercise of this Debenture (without regard to any limitations on conversion hereof, including
without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution,
or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the
participation in such Distribution (provided, however, to the extent that the Holder's right to participate in any
such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled
to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of
such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder
until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).


 




    	16



    	 



    

 


e)         Fundamental
Transaction. If, at any time while this Debenture is outstanding, (i) the Company, directly or indirectly, in one or more related
transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly,
effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets
in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether
by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange
their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Common
Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization
or recapitalization 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, or (v) the Company, directly or indirectly, in one or more related transactions
consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization,
recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the
outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or
party to, or associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other
business combination) (each 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 (without regard to any limitation in Section 4(d) on the conversion of
this Debenture), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result
of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Debenture is convertible immediately
prior to such Fundamental Transaction (without regard to any limitation in Section 4(d) on the conversion of this Debenture). 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 (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. The
Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor
Entity”) to assume in writing all of the obligations of the Company under this Debenture and the other Transaction Documents
(as defined in the Purchase Agreement) in accordance with the provisions of this Section 5(e) pursuant to written agreements in
form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such
Fundamental Transaction and shall, at the option of the holder of this Debenture, deliver to the Holder in exchange for this Debenture
a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Debenture
which is convertible for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent
to the shares of Common Stock acquirable and receivable upon conversion of this Debenture (without regard to any limitations on
the conversion of this Debenture) prior to such Fundamental Transaction, and with a conversion price which applies the conversion
price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant
to such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such
conversion price being for the purpose of protecting the economic value of this Debenture immediately prior to the consummation
of such Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence
of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the
date of such Fundamental Transaction, the provisions of this Debenture and the other Transaction Documents referring to the “Company”
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Debenture and the other Transaction Documents with the same effect as if such Successor Entity
had been named as the Company herein.


 




    	17



    	 



    

  


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 Conversion Price. Whenever the Conversion 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 after such adjustment and setting forth a brief statement
of the facts requiring such adjustment.


 




    	18



    	 



    

 


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, or 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. To the
extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any
of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form
8-K. The Holder shall remain 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 except as may otherwise be expressly set forth herein.

Section 6.          Optional
Redemption and Periodic Redemption.


 





a)         Optional
Redemption at Election of Company. Subject to the provisions of this
Section 6(a), at any time after the 6 month anniversary of the Closing 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 some or all of the then outstanding principal amount of this Debenture for cash in an amount equal to the Optional Redemption
Amount on the 10th Trading Day following the Optional Redemption Notice Date (such date, the “Optional
Redemption Date”, such 10 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 may only effect an Optional Redemption if each of the Equity Conditions shall
have been met (unless waived in writing by the Holder) on each Trading Day during the period commencing on the Optional Redemption
Notice Date through to the Optional Redemption Date and through and including the date payment of the Optional Redemption
Amount is actually made in full. If any of the Equity Conditions shall cease
to be satisfied at any time during the Optional Redemption 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 on which any such Equity Condition has not been met (provided
that if, by a provision of the Transaction Documents, the Company is obligated to notify the Holder of the non-existence of an
Equity Condition, such notice period shall be extended to the third Trading Day after proper notice from the Company) 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 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 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.


 


Notwithstanding
the foregoing, the Company shall have the right to make an Optional Redemption pursuant to the terms of this Section 6(a) during
the period from the Closing Date until the 6 month anniversary of the Closing Date (“Conditional Period”), provided
that, in addition to the requirements of Section 6(a), the Company satisfies the following additional conditions in connection
with an Optional Redemption during the Conditional Period: the Company shall make the Optional Redemption solely with funds that
are raised in a public or private offering of securities of the Company (the “Financing”), shall make the Optional
Redemption within 10 Trading Days of the closing of the Financing and shall pay the Optional Redemption Amount to the Holder from
an escrow account which holds the proceeds of the Financing.


 




    	20



    	 



    

 


b)         Mandatory
Periodic Redemption. On each Periodic Redemption Date, the Company shall redeem the Periodic Redemption Amount (the “Periodic
Redemption”). The Periodic Redemption Amount payable on each Periodic Redemption Date shall be paid in cash; provided,
however, that, as to any Periodic Redemption and upon 20 Trading Days’ prior written irrevocable notice (the “Periodic
Redemption Notice” and such 20 Trading Day period, the “Periodic Redemption Period”), in lieu of a
cash redemption payment, the Company may elect to pay all or part of a Periodic Redemption Amount in Conversion Shares (the dollar
amount to be paid in shares, the “Periodic Redemption Share Amount”) based on a conversion price equal to the
Conversion Price; provided, further, that the Company may not pay the Periodic Redemption Amount in Conversion
Shares unless (y) on each Trading Day during the period commencing on date of the Periodic Redemption Notice through to the date
of the Periodic Redemption, the Equity Conditions have been satisfied, unless waived in writing by the Holder, and (z) as to such
Periodic Redemption, prior to the 10th Trading Day prior to the Periodic Redemption Date (the “Periodic Redemption
Conversion Pre-Delivery Date”), but not more than 5 Trading Days prior to the Periodic Redemption Conversion Pre-Delivery
Date, 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 Periodic Redemption Share Amount equal to the quotient of (x) the applicable Periodic Redemption
Share Amount divided by (y) the Conversion Price (the “Pre-Periodic Redemption Conversion
Shares”). The Holder may convert, pursuant to Section 4(a), any principal amount of this Debenture subject to a Periodic
Redemption at any time prior to the date that the Periodic Redemption Amount, plus accrued but unpaid interest, liquidated damages
and any other amounts then owing to the Holder are due and paid in full. Unless otherwise indicated by the Holder in the applicable
Notice of Conversion, any principal amount of this Debenture converted from the delivery date of the applicable Periodic Redemption
Notice until the date the Periodic Redemption Amount is paid in full shall be first applied to the principal amount subject to
the Periodic Redemption Amount payable in cash and then to the Periodic Redemption Amount payable in Conversion Shares. Any principal
amount of this Debenture converted during the period beginning on the delivery date of the applicable Periodic Redemption Notice
and ending on the date the Periodic Redemption Amount is paid in full in excess of the Periodic 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 against such Periodic Redemption Amount, the Pre-Periodic
Redemption Conversion Shares, if any were issued in connection with such Periodic 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 Notices of
Conversion tendered up until such amounts are paid in full. The Company’s determination to pay a Periodic Redemption in cash,
shares of Common Stock or a combination thereof 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. At any time the
Company delivers a notice to the Holder of its election to pay the Periodic Redemption Amount in shares of Common Stock, if a registration
statement is then effective, the Company shall file a prospectus supplement pursuant to Rule 424 disclosing such election.


 


c)         Redemption
Procedure. The payment of cash or issuance of Common Stock, as applicable, pursuant to an Optional Redemption or a Periodic
Redemption shall be payable on the Optional Redemption Date or Periodic Redemption Date, respectively. If any portion of the payment
pursuant to an Optional Redemption or a Periodic 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 or Periodic 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 or Periodic 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 or its elections under Section 6(b) 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.

Section
7.          Negative Covenants. As long as any portion of this Debenture
remains outstanding, unless the holders of at least 67% 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 the Subsidiaries 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

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 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

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

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
on any other occasion. 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 Debenture, 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)         Secured
Obligation. The Company acknowledges and agrees that the obligations of the Company under this Debenture are subject to the
security interest granted by the Company and its Subsidiaries pursuant to that certain Security Agreement, dated as of March 27,
2013 (“Security Agreement”), between the Company, the Subsidiaries of the Company and the Secured Parties (as
