Debenture is registered on the records of the Company regarding registration and transfers of this Debenture (the “Debenture Register”). 
 b) Company’s Election to Pay Interest in Cash. The Company may, at its option, pay in cash all or a portion of the accrued and unpaid interest on the Debentures at


  
 6 








 
any time and from time to time. Any such payment shall be made pari passu among the Holders of the then outstanding debentures. At least ten (10) days prior to the date proposed for

(10) day period (the “Interest Notice Period”), the Company’s election shall be irrevocable as to such Interest Payment Date. 
 c) 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.

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 and all accrued but unpaid interest thereon 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)). 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, whether accrued and unpaid interest on such
principal is also to be converted, and the date on which such conversion shall be effected (such date, the “Conversion Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that
such Notice of Conversion is deemed delivered hereunder. To effect conversions hereunder, the Holder shall not be required to 

  
 7 








 
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 and accrued interest on 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) and the accrual of interest on this Debenture. 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 $0.05, 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 and accrued interest of this Debenture to be converted by (y) the Conversion Price. 

ii. Delivery of Certificate Upon Conversion. Not later than three (3) Trading Days after each Conversion Date
(the “Share Delivery Date”), the Company shall deliver, or cause to be delivered, to the Holder (A) a certificate or certificates representing the Conversion Shares which, on or after the earlier of (i) the six month
anniversary of the Original Issue Date (if the Company is then current in its reporting under the Exchange Act, and the Holder is not an Affiliate of the Company, otherwise then the one year anniversary of the Original Issue Date) or (ii) the
Effective Date, shall be free of restrictive legends and trading restrictions (other than those which may then be required by the Purchase Agreement) representing the number of Conversion Shares being acquired upon the conversion of this Debenture
and (B) a bank check in the amount of accrued and unpaid interest (if the Company has elected or is required to pay accrued interest in cash). On or after the earlier of (i) the six month anniversary of the Original Issue Date or
(ii) the Effective Date, the Company shall to the extent requested by the converting Holder use its best efforts to 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. 

  
 8 








 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 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. 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. The Holder shall have the 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 

  
 9 








 
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, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holder
(and the other holders of the Debentures), not less than such aggregate number of shares of the Common Stock as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments and
restrictions of Section 5) upon the conversion of the then 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 authorized, validly issued,
fully paid and nonassessable. 

  
 10 









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

  
 11 









 
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 (2) 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. 
 b) Subsequent Rights Offerings. In addition to any adjustments pursuant to
Section 5(a) above, if at any time while this Debenture is outstanding 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). 
 c)
Pro Rata Distributions. If the Company, at any time while this Debenture is outstanding, distributes to all holders of Common Stock (and not to the Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights
or warrants to subscribe for or purchase any security, 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 VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record date less the then fair market value at such record
date of the portion of such assets or evidence of indebtedness or rights or warrants so distributed applicable to one outstanding share of the Common Stock as determined by the Board of Directors of the Company in good faith. In either case the
adjustments shall be described in a statement delivered to the Holder describing the portion of assets or evidences of indebtedness so distributed or such subscription rights applicable to 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. 

  
 13 









 d) 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 (excluding specifically the license or other disposition of the Company’s intellectual property
in the ordinary course of business), (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, (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


  
 14 









 
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(d) 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. 

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 any treasury
shares of the Company) issued and outstanding. 
 f) 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. 

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 

  
 15 









 
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. Forced Conversion. Notwithstanding anything herein to the contrary, if after the Effective Date, the VWAP
for each of any 30 consecutive Trading Days, which period shall have commenced only after the Effective Date (such period the “Threshold Period”), exceeds $0.25 (subject to adjustment for reverse and forward stock splits, stock
dividends, stock combinations and other similar transactions of the Common Stock that occur after the Original Issue Date), the Company may, within two (2) Trading Days after the end of any such Threshold Period, deliver a written notice to the
Holder (a “Forced Conversion Notice” and the date such notice is delivered to the Holder, the “Forced Conversion Notice Date”) to cause the Holder to convert all or part of the then outstanding principal amount of
this Debenture plus, if so specified in the Forced Conversion Notice, accrued but unpaid interest, liquidated damages and other amounts owing to the Holder under this Debenture (“Forced Conversion”), it being agreed that the
“Conversion Date” for purposes of Section 4 shall be deemed to occur on the third Trading Day following the Forced Conversion Notice Date (such third Trading Day, the “Forced Conversion Date”). The Company may not
deliver a Forced Conversion Notice, and any Forced Conversion Notice delivered by the Company shall not be effective, unless all of the Equity 

  
 16 









 
Conditions are met (unless waived in writing by the Holder) on each Trading Day occurring during the applicable Threshold Period through and including the later of the Forced Conversion Date and
the Trading Day after the date such Conversion Shares pursuant to such conversion are delivered to the Holder. Any Forced Conversion shall be applied ratably to all Holders based on their initial purchases of Debentures pursuant to the Purchase
Agreement, provided that any voluntary conversions by a Holder shall be applied against the Holder’s pro rata allocation, thereby decreasing the aggregate amount forcibly converted hereunder if only a portion of this Debenture is forcibly
converted. For purposes of clarification, a Forced Conversion shall be subject to all of the provisions of Section 4, including, without limitation, the limitations on conversions; provided, however, that to the extent the Forced Conversion of
this Debenture is limited by such limitations on conversions, then the rate of interest on this Debenture shall reduced to zero (0%). 
 Section 7. Negative Covenants. As long as at least 25% of the original aggregate principal amount of all Debentures remains outstanding, unless the holders of at least 67% in principal
amount of the then outstanding Debentures (and treating any Debentures owned by the Company or any Affiliate of the Company as not outstanding for such purpose) 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 its charter documents, including, without limitation, its certificate of incorporation and bylaws, in any manner
that materially and adversely affects any rights of the Holder (which limitation shall expressly not apply to any proposal to increase the number of authorized shares of the Company’s Common Stock); 

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

e) repay, repurchase or offer to repay, repurchase or otherwise acquire any Indebtedness, other than the Debentures if on
a pro-rata basis, other than regularly scheduled principal and interest payments as such terms are in effect as of the Original Issue Date, provided that such payments shall not be permitted if, at such time, or immediately after giving effect to
such payment, any Event of Default exists or would occur; 

  
 17 









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

Section 8. Events of Default. 
 a) “Event of Default” means, wherever used herein, any of the following events (whatever the reason for such event and whether such event shall be voluntary or involuntary or effected by
operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body) and except as shall have been effected with the consent of the Holders in accordance with
Section 7: 
 i. any default in the payment of (A) the principal amount of any Debenture or

calendar days; 
 ii. the Company shall fail to observe or perform any other covenant or agreement contained in
the Debentures (other than a breach by the Company of its obligations to deliver shares of Common Stock to the Holder upon conversion, which breach is addressed in clause (ix) below) which failure is not cured, if possible to cure, within the
earlier to occur of (A) five (5) Trading Days after notice of such failure sent by the Holder or by any other Holder to the Company and (B) 10 Trading Days after the Company has become or should have become aware of such failure;

 iii. a default or event of default (subject to any grace or cure period provided in the applicable agreement,
document or instrument) shall occur under (A) any of the Transaction Documents or (B) any other material agreement, lease, document or instrument to which the Company or any Subsidiary is obligated (and not covered by clause
(vi) below); 

  
 18 









 iv. any representation or warranty made in this Debenture, any other

when made or deemed made; 
 v. the Company or any Significant Subsidiary (as such term is defined in Rule
1-02(w) of Regulation S-X) shall be subject to a Bankruptcy Event; 
 vi. the Company or any Subsidiary shall
default on 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, any indebtedness
for borrowed money or money due under any long term leasing or factoring arrangement that (a) involves an obligation greater than $150,000, whether such indebtedness now exists or shall hereafter be created, and (b) results in such
indebtedness becoming (subject to any applicable cure period) or being declared due and payable prior to the date on which it would otherwise become due and payable; 

vii. the Common Stock shall not be eligible for listing or quotation for trading on a Trading Market and shall not be
eligible to resume listing or quotation for trading thereon within five Trading Days; 
 viii. the Company shall
be a party to any Change of Control Transaction or Fundamental Transaction or shall agree to sell or dispose of all or in excess of 33% of its assets in one transaction or a series of related transactions (whether or not such sale would constitute a
Change of Control Transaction) and excluding specifically any license or other disposition involving continued royalty or similar payments of the Company’s intellectual property assets in the ordinary course of business); 

ix. the Company shall fail for any reason to deliver certificates to a Holder prior to the fifth Trading Day after a
Conversion Date pursuant to Section 4(c) or any Forced Conversion Date pursuant to Section 6(d) or the Company shall provide at any time notice to the Holder, including by way of public announcement, of the Company’s intention to not
honor requests for conversions of any Debentures in accordance with the terms hereof; 
 x. the Company shall
materially breach any agreement delivered to the initial Holders pursuant to Section 2.2 of the Purchase Agreement; or

 19 









 b) Remedies Upon Event of Default. If any Event of Default occurs,
the outstanding principal amount of this Debenture, plus accrued but unpaid interest, and other amounts owing in respect thereof through the date of acceleration, shall become, at the Holder’s election and upon notice thereof to the Company,
immediately due and payable in cash at the Mandatory Default Amount. Commencing five (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 an interest rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. Upon the payment in full of the Mandatory Default Amount, the Holder shall promptly surrender this Debenture to or as directed
by the Company. In connection with such acceleration described herein, 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 enforce any and all of
its rights and remedies hereunder and all other remedies available to it under applicable law. Such acceleration may be rescinded and annulled by Holder at any time prior to payment hereunder and the Holder shall have all rights as a holder of the
Debenture until such time, if any, as the Holder receives full payment pursuant to this Section 8(b). No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon. 

Section 9. Miscellaneous. 
 a) Notices. Any and all notices or other communications or deliveries to be provided by the Holder hereunder, including, without limitation, any Notice of Conversion, shall be in writing and
delivered personally, by facsimile, or sent by a nationally recognized overnight courier service, addressed to the Company, at the address set forth above, or such other facsimile number or address as the Company may specify for such purposes by
notice to the Holder delivered in accordance with this Section 9(a). Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and delivered personally, by facsimile or e-mail to the
facsimile number or e-mail address set forth on the signature page hereto (or subsequently delivered to the Company), or sent by a nationally recognized overnight courier service addressed to each Holder at the address of the Holder appearing on the
books of the Company, or if no such address appears on the books of the Company, at the principal place of business of such Holder, as set forth in the Purchase Agreement. Any notice or other communication or deliveries hereunder shall be deemed
given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile or e-mail prior to 5:30 p.m. (New York City time) on any date, (ii) the next Trading Day after the date of
transmission, if such notice or communication is delivered via facsimile or e-mail on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (iii) the second Trading Day following the date of mailing,
if sent by U.S. nationally recognized overnight courier service or (iv) upon actual receipt by the party to whom such notice is required to be given. 
 b) Absolute Obligation. Except as expressly provided herein, no provision of this Debenture shall alter or impair the obligation of the Company, which is absolute and


  
 20 









 
unconditional, to pay the principal of, liquidated damages and accrued interest, as applicable, 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 a lost, stolen or destroyed Debenture, a new Debenture for the principal amount of this Debenture so
mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or destruction of such Debenture, and of the ownership hereof, 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 conflict of laws thereof. Each party agrees that all legal proceedings concerning the
interpretation, enforcement and defense of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders, employees or agents) shall be
commenced in the state and federal courts sitting in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the
adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for such proceeding. Each party hereby
irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at
the address in effect for notices to it under this Debenture and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve
process in any other manner permitted by applicable law. Each party hereto hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this
Debenture or the transactions contemplated hereby. If any party shall commence an action or proceeding to enforce any provisions of this Debenture, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its
attorneys’ fees and other costs and expenses incurred in the investigation, preparation and prosecution of such action or proceeding. 
 e) Amendments, Waivers. No provision of the Debentures may be waived, modified, supplemented or amended except in a written instrument signed by the Company and Required Holders, which upon
execution of such written instrument shall 

  
 21 









 
be effective as to all Debentures then outstanding. Any waiver by the Company or the Required Holders of a breach of any provision of the Debentures 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 the Debentures. The failure of the Company or the Required Holders to insist upon strict adherence to any term of the 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 the Debentures on any other occasion. Any waiver by the Company or the Required Holders 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
obligations of the Company under this Debenture are secured by all assets of the Company pursuant to the Security Agreement, dated as of June 16, 2011 between the Company and the Secured Parties (as defined therein).
