from the date such interest is due hereunder through and including the date of actual payment of such overdue amount 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.

e)
Prepayment at the Option of the Holder. The Holder shall have the right, at any time and from time to time, to require the Company to prepay in cash all, or any portion, of the outstanding principal amount of this Debenture plus all accrued and unpaid interest thereon by delivering a written notice (a “Prepayment Notice”) to the Company specifying the principal amount and accrued interest thereon to be prepaid (the “Prepayment Amount”); provided, that the Prepayment Amount shall not exceed the lesser of (1) eighteen million five hundred thousand dollars ($18,500,000) and (2) the outstanding principal amount of this Debenture plus all accrued and unpaid interest thereon. Any prepayment of this Debenture pursuant to the preceding sentence shall be due and payable in cash on the first (1^st) Trading Day after the Company’s receipt of such Prepayment Notice (the “Prepayment Date”).

f)
Prepayment at the Option of the Company. Notwithstanding anything contained herein to the contrary, except as expressly set forth in Section 2(e), prior to the date that is eighteen (18) months following the Original Issue Date, the Company may not prepay all or any portion of this Debenture without the prior written consent of the Holder. Notwithstanding the foregoing, the Company may prepay all, but not less than all, of this Debenture in cash by paying to the Holder an amount in cash equal to one hundred ten percent (110%) of the entire outstanding principal balance plus all accrued and unpaid interest thereon at any time (i) following such 18-month period, or (ii) upon consummation of a Change of Control, in each case, upon ten (10) Trading Days’ prior written notice to the Holder. Such prepayment shall be made by the Company by wire transfer of immediately available funds to the Holder, in the case of clause (i), immediately upon the expiration of such ten (10) Trading Day notice period or, in the case of clause (ii), upon (but not earlier than) the consummation of the Change of Control. For the avoidance of doubt, the Holder shall be entitled to convert all or any portion of this Debenture pursuant to Section 4(b) until the Company makes such prepayment in immediately available funds in accordance with the preceding sentence.

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.
Redemption; Voluntary Conversion at the Option of the Holder; Delivery of Stock Payment Shares and Conversion Shares.

a)
Monthly Redemption.

i.
Commencing on November 10, 2016 (the “Monthly Redemption Commencement Date”) the Holder shall have the right, at its option (except as expressly provided in Section 4(a)(i)(B)), to require the Company to redeem up to the Monthly Allowance per calendar month (the “Holder Redemption Right”). The Company may, at its option, increase, and only increase, the dollar amount of the Monthly Allowance in effect for any calendar month by delivering a written notice to the Holder at any time during such calendar month prior to 7:00 a.m. (local time in New York City, New York) on the third (3^rd) to last Trading Day of such calendar month; such notice may also indicate that the increase contained in such notice shall apply to future calendar months until revised by a subsequent notice. In addition, the Holder shall have the right, at its option, to increase the dollar amount of the Monthly Allowance to an amount equal to two million five hundred thousand dollars ($2,500,000) for any calendar month by delivering a written notice to the Holder at any time during such calendar month; provided, that the Holder may not exercise this right with respect to more than three (3) calendar months in any twelve (12) month period. The Exercise

of the Holder Redemption Right shall be exercised in accordance with the following procedures:

(A)
The Holder may exercise its Holder Redemption Right for a calendar month, at any time and from time to time, during such calendar month, by sending one (1) or more, but not more than six (6), written notices, the form of which is attached hereto as Annex A (each a “Holder Redemption Notice”), to the Company by not later than 11:59:59 P.M. (local time in New York City, New York) on the last Trading Day of such calendar month, which Holder Redemption Notices shall specify the principal amount to be redeemed and the amount of accrued and unpaid interest thereon (together, the “Holder Redemption Amount”).

(B)
At any time after the Monthly Redemption Commencement Date that this Debenture is Stock On, the Company may require the Holder to exercise its Holder Redemption Right for an amount up to the lesser of (i) two million two hundred thousand dollars ($2,200,000) principal amount of this Debenture (but not less than the Monthly Allowance) or (ii) the remaining outstanding principal amount of this Debenture, in each case, during any calendar month other than November, 2016 (the “Company Force Right”) by delivering a written notice to the Holder three (3) Trading Days prior to the first (1^st) Trading Day of such calendar month (the “Company Force Notice”), which Company Force Notice shall indicate the principal amount for which the Holder is required to exercise its Holder Redemption Right (the “Company Force Amount”) and certify that this Debenture is Stock On on the date of the Company Force Notice, that all of the Equity Conditions are satisfied and that the Company reasonably believes, in good faith, that the Equity Conditions will continue to be satisfied for at least such calendar month. For the avoidance of doubt and notwithstanding anything contained herein to the contrary, in no event shall the Company Force Amount exceed the Dollar Volume Limitation. During any calendar month for which the Company has exercised the Company Force Right, the Holder shall deliver at least one (1) but not more than six (6) Holder Redemption Notices to the Company from time to time during such calendar month for an aggregate Holder Redemption Amount equal to the Company Force Amount (and, for the avoidance of doubt, if the Company Force Amount is less than the Monthly Allowance, nothing herein shall be deemed to prevent the Holder from submitting additional Holder Redemption Notices for Holder Redemption Amounts in excess of the Company Force Amount up to the Monthly Allowance). Notwithstanding the foregoing, if an Equity Conditions Failure occurs during such calendar month, the Holder shall have no further obligation (but shall, for the avoidance of doubt, retain the option to do so) to submit Holder Redemption Notices during such calendar month

unless such Equity Conditions Failure is waived in writing by the Holder; provided, however, following the date of any such Equity Conditions Failure (to the extent not waived by the Holder) the Holder may not submit Holder Redemption Notices for such calendar month in excess of the Monthly Allowance (for the avoidance of doubt, the Company shall be required to honor all Holder Redemption Notices delivered prior to the date of the Equity Conditions Failure in accordance with Section 4(a)(v)). On the Trading Day prior to the first (1^st) Trading Day of any calendar month for which the Company has exercised the Company Force Right (the “Advance Date”), the Company shall deliver to the Holder’s or its designee’s balance account with DTC a number of shares of Common Stock (free of any restrictive legends or other trading restrictions) equal to the quotient of (x) the Company Force Amount and (y) the Stock Payment Price for the Advance Date (the “Monthly Redemption Advance Shares”).

(C)
The Company shall promptly, but in any event no more than three (3) Trading Days after the date that the Holder delivers a Holder Redemption Notice to the Company (the “Holder Redemption Payment Date”), pay the applicable Holder Redemption Amount (1) in cash, to the extent that this Debenture is Stock Off (as defined below) on the date that the Holder delivers the Holder Redemption Notice to the Company, equal to the Holder Redemption Amount by wire transfer of immediately available funds or (2) in shares of Common Stock, to the extent that this Debenture is Stock On (as defined below) on the date that the Company delivers the Holder Redemption Notice, in accordance with this Section 4.

(D)
For the avoidance of doubt, payment of the Holder Redemption Amount in cash or Common Stock shall be determined according to the status of the Debenture as Stock On or Stock Off on the date that the Holder delivers the Holder Redemption Notice to the Company and not the Holder Redemption Payment Date. For the further avoidance of doubt, the Holder and the Company agree that the Holder may deliver up to three (3) Holder Redemption Notices during a calendar month; provided, that during any calendar month for which the Company has exercised the Company Force Right, the Holder may deliver up to six (6) Holder Redemption Notices to the Company during such calendar month, provided, further, and for the avoidance of doubt, that the sum of the Holder Redemption Amounts set forth in all of the Holder Redemption Notices delivered during such calendar month does not exceed the Monthly Allowance or, if applicable, the Company Force Amount.

(E)
Each of the Holder and the Company acknowledge the Company’s

obligation under Section 4.8(a) of the Purchase Agreement to not provide any material non-public information to the Holder, and the Holder agrees that the Company shall have no liability to the Holder for failing to disclose any material non-public information in connection with the issuance of any Stock Payment Shares to Holder in accordance with the terms of this Debenture.

ii.
At any time, and from time to time, subject to the provisions of this Section 4(a), the Company may, at its option, deliver a written notice to the Holder that it will pay any Holder Redemption Amounts under Section 4(a)(i) in shares of Common Stock (a “Stock On Notice”) and any such notice shall become effective on the fifth (5^th) Trading Day after the Holder’s receipt thereof (the “Stock On Effective Date”). Such Stock On Notice shall certify that the Equity Conditions are satisfied on the date thereof, and each of the twenty (20) consecutive Trading Days immediately preceding the date of such Stock On Notice, and at any time that this Debenture is Stock On, the Company shall, upon the Holder’s request, certify in writing to the Holder that the Equity Conditions are satisfied and that the Company reasonably believes, in good faith, that the Equity Conditions will continue to be satisfied for the foreseeable future. From the time that a Stock On Notice takes effect until such time that such Stock On Notice is withdrawn pursuant to Section 4(a)(iv) or deemed withdrawn pursuant to Section 4(a)(iii), this Debenture shall be deemed to be “Stock On.” At any time that this Debenture is not Stock On, then this Debenture shall be deemed to be “Stock Off.” For the avoidance of doubt, the Holder may deliver a Holder Redemption Notice during the period after receipt of the Stock On Notice but prior to the Stock On Effective Date; the Debenture shall be Stock Off during such period and, accordingly, the applicable Holder Redemption Amount would be payable in cash. Notwithstanding anything contained herein to the contrary, and subject to the satisfaction of all of the requirements set forth in this Section 4(a) for the delivery of a Stock On Notice (including, without limitation, the satisfaction of the Equity Conditions), the Company shall, to the extent that this Debenture is not already Stock On, be required to deliver a Stock On Notice to the Holder at any time that the Company’s Cash on Hand does not exceed the outstanding principal amount of this Debenture by more than ten million dollars ($10,000,000) (for the avoidance of doubt, any Stock On Notice required to be delivered pursuant to this sentence shall not disclose the Company’s Cash on Hand or otherwise contain any material, non-public information).

iii.
The Company may not deliver a Stock On Notice unless the Equity Conditions are satisfied on the date thereof and on each of the twenty (20) consecutive Trading Days immediately preceding such date. If the Equity Conditions cease, for any reason, to be satisfied while this Debenture is Stock On, then the applicable Stock On Notice shall, unless such Equity Conditions Failure is waived by the Holder in writing, automatically without any further action of the Company or the Holder, immediately be deemed to be withdrawn and this Debenture shall immediately be deemed to be Stock Off (an “Equity

Conditions Failure”). The Company shall immediately notify the Holder of any Equity Conditions Failure.

iv.
The Company may voluntarily withdraw a Stock On Notice by delivering a written notice (a “Stock Off Notice”) to the Holder and such Stock On Notice shall be deemed withdrawn and this Debenture shall be Stock Off five (5) Trading Days after receipt thereof by the Holder (the “Voluntary Stock Off Effective Date”); provided, however, the Company may not, unless the Holder otherwise consents in writing, deliver a Stock Off Notice during any calendar month for which the Company has exercised the Company Force Right if the related Voluntary Stock Off Effective Date would occur during such calendar month or if the Company would be required to deliver a Stock On Notice pursuant to the last sentence of Section 4(a)(ii). For the avoidance of doubt, the Holder may deliver a Holder Redemption Notice during the period after receipt of the Stock Off Notice but prior to the Voluntary Stock Off Effective Date; the Debenture shall be Stock On during such period and, accordingly, the applicable Holder Redemption Amount would be payable in shares of Common Stock on the applicable Holder Redemption Payment Date as provided herein.

v.
With respect to each Holder Redemption Notice delivered to the Company pursuant to Section 4(a)(i) at a time when this Debenture was Stock On, subject to the provisions of this Section 4(a)(v), the Company shall, in payment of the Holder Redemption Amount deliver to the Holder, or its designee, a number of Stock Payment Shares equal to the quotient of (x) the applicable Holder Redemption Amount and (y) the Stock Payment Price by not later than the applicable Holder Redemption Payment Date. With respect to any Holder Redemption Notice delivered to the Company during a calendar month for which the Company has exercised the Company Force Right and for which calendar month the Holder has actually received the applicable Monthly Redemption Advance Shares, the number of Stock Payment Shares deliverable pursuant to the immediately preceding sentence shall be reduced by the excess (if any) of the Monthly Redemption Advance Shares over the aggregate number of Stock Payment Shares that would be deliverable pursuant to the immediately preceding sentence for all other Holder Redemption Notices delivered during such calendar month (“Available Advance Shares”). The Holder’s calculation of the Available Advance Shares set forth on the Holder Redemption Notice shall be binding on the Company absent manifest error. Notwithstanding the foregoing or any other provision herein to the contrary:

(A)
in the event any Equity Conditions Failure occurs after the delivery of the applicable Holder Redemption Notice at a time when this Debenture is Stock On but prior to the applicable Holder Redemption Payment Date, at the option of the Holder, (1) the Company shall pay to the Holder an amount in cash equal to the Holder Redemption Amount, and (2) the Holder shall, if applicable, return a number of Monthly Redemption Advance Shares to the Company equal to the applicable number of Stock Payment Shares;

(B)
in the event that the aggregate number of Stock Payment Shares to be delivered to the Holder pursuant to this Section 4(a)(v) in respect of any individual Holder Redemption Notice would cause such Holder to exceed the Beneficial Ownership Limitation or the Exchange Cap, then, (I) the Holder shall provide written notice to the Company that such delivery of all or a portion of such Stock Payment Shares would cause the Holder to exceed the Beneficial Ownership Limitation or the Exchange Cap, and (II) in addition to delivery of the number of Stock Payment Shares that would not cause such Holder to exceed the Beneficial Ownership Limitation or Exchange Cap, as applicable, the Company shall pay to the Holder, in lieu of such number of Stock Payment Shares that would cause the Holder to exceed the Beneficial Ownership Limitation or Exchange Cap, as applicable (such excess number of shares, the “Excess Shares”), on the applicable Holder Redemption Payment Date, an amount in cash equal to the portion of the Holder Redemption Amount that would otherwise be payable in respect of the Excess Shares;

(C)
in the event that the Holder Redemption Amount in respect of any Holder Redemption Notice, when aggregated with the Holder Redemption Amounts in respect of each other Holder Redemption Notice delivered to the Company during the same calendar month, would exceed the Dollar Volume Limitation, then the Company shall pay the portion of the Holder Redemption Amount that would be in excess of the Dollar Volume Limitation in cash; and/or

(D)
with respect to any calendar month for which the Company has exercised the Company Force Right and for which calendar month the Holder has actually received Monthly Redemption Advance Shares, if there are any Available Advance Shares remaining after all Holder Redemption Notices for such calendar month have been satisfied in full, the Holder shall promptly return such remaining Available Advance Shares to the Company.

b)
Voluntary Conversion at the option of the Holder.

1.Voluntary Conversion. Commencing on the Monthly Redemption Commencement Date, and thereafter from time to time 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, subject to the conversion limitations set forth in Section 4(h) and Section 4(i). The Holder shall effect conversions by delivering to the Company a Notice of Conversion, the form of which is attached hereto as Annex B (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). 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.

2.Conversion Price. The conversion price in effect on any Conversion Date shall be equal to $0.60, subject to adjustment herein (the “Conversion Price”).

3.Conversion Shares Issuable Upon Conversion of Principal Amount; Delivery Date. 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 plus accrued and unpaid interest thereon by (y) the Conversion Price. The Company shall deliver all Conversion Shares to the Holder within two (2) Trading Days after the date of the applicable Notice of Conversion (the “Conversion Share Delivery Date”).

c)
Delivery of Certificate for Stock Payment Shares and Conversion Shares. The Company shall deliver any certificate or certificates evidencing Stock Payment Shares or Conversion Shares, as applicable required to be issued by the Company pursuant to Section 4(a)(v) or Section 4(b), as applicable, electronically through DTC without restrictive legends or trading restrictions of any kind not later than the applicable Holder Redemption Payment Date or Conversion Share Delivery Date, as applicable; provided, that prior to the twelve (12) month anniversary of the Original Issue Date, in order for such certificate or certificates to be issued without restrictive legends, (i) the Company shall be in compliance with the current public information requirements of Rule 144 and (ii) the Holder shall have delivered to the Company a broker representation letter that the shares of Common Stock represented by such certificate or certificates have been sold pursuant to Rule 144. The Company shall, at its own expense, cause Company Counsel to issue any legal opinions required to issue such Interest Advance Shares, Monthly Redemption Advance Shares, Stock Payment Shares and/or Conversion Shares without any restrictive legends as provided herein, such legal opinion to be in a form acceptable to the Holder. Company Counsel’s form of Rule 144 legal opinion is attached hereto in substantially the form of Annex C. If such certificate or certificates are not delivered to or as directed by the applicable Holder Redemption Payment Date or Conversion Share Delivery Date, as applicable, the Holder shall, in addition to, and

not in limitation of, its other rights and remedies under this Debenture and the other Transaction Documents, 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 the applicable Holder Redemption Notice or Notice of Conversion, as applicable.

d)
Obligation Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver Stock Payment Shares and Conversion Shares 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 Stock Payment Shares or 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. The Company may not refuse to issue any Stock Payment Shares or Conversion Shares required to be issued hereunder 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, shall have been sought and obtained, and the Company posts a surety bond for the benefit of the Holder in the amount of one hundred and fifty percent (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 Stock Payment Shares and Conversion Shares required to be issued hereunder in accordance with the terms hereof. If the Company fails for any reason to deliver to the Holder such certificate or certificates representing Stock Payment Shares or Conversion Shares required to be issued pursuant to Section 4(a)(v) or Section 4(b), as applicable, by the second Trading Day following the applicable Holder Redemption Payment Date or Conversion Share Delivery Date, as applicable, the Company shall pay to the Holder, in cash, as partial liquidated damages and not as a penalty, for each one thousand dollars ($1,000) of principal amount being redeemed or converted, as applicable, $5 per Trading Day for each Trading Day after the second Trading Day following such Holder Redemption Payment Date or Conversion Share Delivery Date, as applicable, until such certificates are delivered or Holder rescinds such redemption or conversion, as applicable; provided, however, if the Company has failed to deliver a certificate or certificates representing Stock Payment Shares or Conversion Shares required to be issued pursuant to Section 4(a)(v) or Section 4(b), as applicable, by the Holder Redemption Payment Date or Conversion Date, as applicable, more than twice in any twelve (12) month period, then such partial liquidated damages shall begin to accrue on the Holder Redemption Payment Date and/or Conversion Share Delivery Date, as applicable. Nothing herein shall limit a ▇▇▇▇▇▇’s right to pursue actual damages or declare an Event of Default pursuant to Section 8 hereof for the Company’s failure to deliver Stock Payment Shares or

Conversion Shares within the period specified in this Debenture 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.

e)
Compensation for Buy-In on Failure to Timely Deliver Certificates. 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 representing Stock Payment Shares or Conversion Shares required to be issued pursuant to Section 4(a)(v) or Section 4(b), as applicable by the applicable Holder Redemption Payment Date or Conversion Share Delivery Date, as applicable, and if after such Holder Redemption Payment Date or Conversion Share Delivery Date, as applicable, 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 Stock Payment Shares or Conversion Shares, as applicable, which the Holder was entitled to receive pursuant to Section 4(a)(v) or Section 4(b), as applicable, relating to such Holder Redemption Payment Date or Conversion Share Delivery Date, as applicable (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 Stock Payment Shares or Conversion Shares, as applicable, that the Holder was entitled to receive from the Holder Redemption Notice or Notice of Conversion, as applicable, 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, rescind the Holder Redemption Notice or Notice of Conversion, as applicable, at issue or deliver to the Holder the number of Stock Payment Shares or Conversion Shares, as applicable, that would have been issued if the Company had timely complied with its delivery requirements under this Section 4. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to a Holder Redemption Notice with respect to which the actual sale price of the Stock Payment 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 Stock Payment Shares or Conversion Shares as required pursuant to the terms hereof.

f)
Fractional Shares. No fractional shares or scrip representing fractional shares shall

be issued under this Debenture. As to any fraction of a share which the Holder would otherwise be entitled, the Company shall round up to the next whole share.

g)
Transfer Taxes and Expenses. The issuance of certificates for Stock Payment Shares and Conversion Shares 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. The Company shall pay all Transfer Agent fees required for processing of any Holder Redemption Notice and all fees to DTC (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Stock Payment Shares and Conversion Shares.

h)
Beneficial Ownership Limitation. Notwithstanding anything to the contrary set forth in this Debenture, at no time may the Company issue to the Holder shares of Common Stock (whether as Stock Payment Shares, Interest Advance Shares, Monthly Redemption Advance Shares, Conversion Shares or otherwise) to the extent that after giving effect to such issuance, 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 this Section 4(h), 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(h) applies, the determination of whether shares of Common Stock may be issued pursuant to this Debenture (in relation to other securities owned by the Holder together with any Affiliates) shall be in the sole discretion of the Holder, and the submission of a Holder Redemption Notice (at a time when this Debenture is Stock On) or Notice of Conversion shall be deemed to be the Holder’s determination of whether shares of Common Stock may be issued pursuant to this Debenture (in relation to other securities owned by the Holder together with any Affiliates) 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 Holder Redemption Notice (at a time that this Debenture is Stock On) or Notice of Conversion that such Holder Redemption Notice 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(h), 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 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 applicable issuance of shares of Common Stock pursuant to this Debenture held by the Holder. The Holder, upon not less than sixty one (61) days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 4(h), 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 applicable issuance of shares of Common Stock pursuant to this Debenture held by the Holder and the Beneficial Ownership Limitation provisions of this Section 4(h) shall continue to apply. Any such increase or decrease will not be effective until the sixty first (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(h) 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.

i)
Principal Market Regulation. The Company shall not issue any shares of Common Stock pursuant to the terms of this Debenture if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the Company may issue pursuant to the terms of this Debenture without breaching the Company’s obligations under the rules or regulations of the Principal Market (the number of shares which may be issued without violating such rules and regulations, the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of shares of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the Holder. The Exchange Cap as of the Original Issue Date is 36,185,586 shares of Common Stock (appropriately adjusted for any stock split, stock dividend, stock combination, stock buy-back or other similar transaction).

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, this Debenture), (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)
Fundamental Transaction. If, at any time while this Debenture is outstanding, the Company effects 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(h) or Section 4(i) on the conversion of this Debenture), the number of shares of capital 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(h) or Section 4(i) 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. For the avoidance of doubt, nothing contained in this Section 5(b) shall be deemed implied consent to any Fundamental Transaction otherwise prohibited by this Debenture or otherwise limit the Holder’s rights under Section 6(a)(vi).

(c)
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.

(d)
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 the 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 ▇▇▇▇▇▇. 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 Fundamental Transaction, Change of Control, 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.

The provisions of this clause shall not be deemed to be implied consent to any Disposition or other transaction (including, without limitation, a Fundamental Transaction or Change of Control) otherwise prohibited by the terms and conditions of this Debenture.

d)
Equity Issuances. Nothing herein shall prohibit the Company from issuing any Equity Interests in any transaction the primary purpose of which is to provide financing to the Company and does not otherwise constitute a Change of Control Transaction.

The Company or any Subsidiary may engage in any Strategic Transaction permitted by this Debenture provided that any such Strategic Transaction, individually or together with other Strategic Transactions entered into by the Company or any Subsidiary, does not have a material adverse effect on the Holder’s or the Agent’s security interest in the Collateral (as defined in the Security Agreement) or the Company’s ability to perform its obligations under this Debenture, including, without limitation, the repayment of the principal amount hereof when and as due hereunder.

This Debenture is a direct debt obligation of the Company.

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.

e)Amendments; Waivers. No provision herein may be waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Holder or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought. No waiver of any default with respect to any provision, condition or requirement of this Debenture shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

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)Remedies, Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Debenture shall be cumulative and in addition to all other remedies available under this Debenture and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Debenture. The Company covenants to the Holder that there shall be no characterization concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any such breach or any such threatened breach, without the necessity of showing economic loss and without any bond or other security being required. The Company shall provide all information and documentation to the Holder that is requested by the Holder to enable the Holder to confirm the Company’s compliance with the terms and conditions of this Debenture.

h)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.

i)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.

j)Secured Obligation. The obligations of the Company under this Debenture are secured by the Collateral (as defined in the Security Agreement) pledged by the Company pursuant to the Security Agreement, dated as of the date hereof, between the Grantors (as defined therein) and the Agent. For the avoidance of doubt, and notwithstanding anything contained herein to the contrary, subject to Permitted Liens, the Holder shall have the first lien over all Collateral, which will rank higher than any other creditor of the Company or its Subsidiaries, to the extent permitted by law.
