Date”) (if any Interest Payment Date is not a Business Day, then the applicable payment shall be due on the next succeeding Business Day), in cash. Notwithstanding the foregoing, to the extent that the Company has elected for this Debenture

Prepayment Period (unless waived by the Holder in writing), the Company may deliver a notice to the Holder and the holders of the other outstanding Debentures (a “Prepayment 

  
 16 








 
Notice” and the date such notice is deemed delivered hereunder, the “Prepayment Notice Date”) of its irrevocable election to redeem all, but not less than all, of the
then outstanding principal amount of this Debenture and the other outstanding Debentures (including, for the avoidance of doubt, any original issue discount) for cash in an amount equal to the Prepayment Amount on the thirtieth (30th) Trading Day
following the Prepayment Notice Date (such date, the “Prepayment Date”, such thirty (30) Trading Day period, the “Prepayment Period”). The Prepayment Amount shall be due and payable in full in cash on the
Prepayment Date. The Company covenants and agrees that it will honor, in accordance with the terms of this Debenture, all Notices of Conversion and, to the extent that this Debenture is Stock On, all Holder Redemption Notices, tendered from the time
of delivery of the Prepayment Notice through the date all amounts owing thereon are due and paid in full. The Company will, concurrently with the delivery of the Prepayment Notice to the Holder, publicly announce its intention to prepay this
Debenture, and if such prepayment is in connection with a Change of Control Transaction, all material terms of such Change of Control Transaction, by means of a Current Report on Form 8-K filed with the
Commission. If any portion of Prepayment Amount shall not be paid by the Company by the Prepayment Date, interest shall accrue thereon at an interest rate equal to the lesser of fifteen percent (15%) per annum or the maximum rate permitted by
applicable law until such amount is paid in full. Notwithstanding anything herein contained to the contrary, if (1) any portion of the Prepayment Amount remains unpaid after the Prepayment Date, (2) the Equity Conditions are not satisfied
during the Prepayment Period, or (3) the prepayment is in connection with a Change of Control Transaction, but the Change of Control Transaction is not consummated within one (1) Trading Day after the payment of the Prepayment Amount,
then, in each case, the Holder may elect, by written notice to the Company given at any time thereafter, to invalidate such prepayment, ab initio. For the avoidance of doubt, the Holder may elect to convert the outstanding principal amount of the
Debenture pursuant to Section 4 prior to actual payment in cash of the Prepayment Amount under this Section 2(c) by the delivery of a Notice of Conversion to the Company. 

Section 3.    Registration of Transfers and Exchanges.

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 

  
 17 








 
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.    Monthly Redemption; Voluntary Conversion; Mandatory
Conversion; Delivery of Debenture Shares. 
 a)    Monthly Redemption. 

i.    Commencing on March 1, 2018, the Holder shall have the right, at its option, to require the
Company to redeem up to the Monthly Allowance per calendar month (the “Holder Redemption Right) in accordance with this Section 4(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 or more 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, 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”). The Company shall promptly, but in any event no more than one (1) Trading Day after the date that the Holder delivers a Holder Redemption Notice to the Company (the “Holder Redemption Payment Date”) (1) if
this Debenture is Stock Off on the date that the Holder delivers the Holder Redemption Notice to the Company, pay to the Holder in cash by wire transfer of immediately available funds an amount equal to the Holder Redemption Amount specified in the
Holder Redemption Notice or (2) if this Debenture is Stock On on the date that the Company delivers the Holder Redemption Notice to the Company, deliver to the Holder shares of Common Stock as provided in this Section 4(a). For the
avoidance of doubt, payment in cash or shares of 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 more than one (1) Holder Redemption Notice during a calendar month provided 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. For the further avoidance of doubt, no reduction in the outstanding principal amount of this Debenture (as a result of
conversion, redemption or otherwise) shall reduce or otherwise have any effect on the amount of the Monthly Allowance, which shall remain unchanged regardless of any such reduction in the outstanding principal amount of this Debenture. 

ii.    With respect to each calendar month during the term of this Debenture, the Company shall elect
whether this Debenture shall be Stock On or Stock Off for such calendar month by delivering, on the fifth (5th) Trading Day prior to the first
(1st) day of such calendar month, a written notice (a “Stock On/Off Notice”) to the Holder of the Company’s election to pay any Holder Redemption Amounts under Section
4(a)(i) 

  
 18 








 
in shares of Common Stock (“Stock On”) or in cash (“Stock Off”) during such calendar month. For the avoidance of doubt, the Company shall make the same election
of Stock On or Stock Off with respect to all of the outstanding Debentures. If the Company fails to deliver the Stock On/Off Notice by the date required herein for any calendar month, the Company shall be deemed to have delivered a Stock On/Off
Notice electing Stock Off for such calendar month. Once delivered (or deemed delivered) a Stock On/Off Notice shall be irrevocable as to the applicable calendar month and the Company may not change its election for such calendar month. If the
Company elects Stock On in such Stock On/Off Notice, then the Company shall certify in such notice that the Equity Conditions are satisfied. In addition, to the extent that the Company elects Stock On, on the Trading Day prior to the first (1st) day of the applicable calendar month (such Trading Day, the “Monthly Redemption Advance Date”), the Company shall deliver to the Holder’s or its broker’s DTC account a
number of freely tradable shares of Common Stock free from restrictive legends (“Monthly Redemption Advance Shares”) equal to the quotient of (x) the Monthly Allowance (plus, if the Company has permitted the issuance of shares
of Common Stock in satisfaction of accrued and unpaid interest as provided in Section 2(a), all interest that would accrue through the applicable Interest Payment Date assuming no reductions in principal from the Monthly Redemption Advance
Date through the applicable Interest Payment Date) and (y) the Stock Payment Price. For the avoidance of doubt and purposes of clarification, the Monthly Redemption Advance Shares are an advance on the Stock Payment Shares that the Holder
anticipates receiving pursuant to Section 4(a)(iv) and shall not be deemed a payment of principal or interest hereunder except as provided in Section 4(a)(iv). 

iii.    If the Equity Conditions cease, for any reason, to be satisfied while this Debenture is Stock On
(an “Equity Conditions Failure”), then, unless such Equity Conditions Failure is waived in writing by the Holder, this Debenture shall immediately be deemed to be Stock Off. The Company shall promptly, but in any event within one
(1) Trading Day, notify the Holder of any Equity Conditions Failure and, unless such Equity Conditions Failure is waived in writing by the Holder, the Company shall not be permitted to make any Holder Redemption Payments during such calendar
month in shares of Common Stock and all Holder Redemption Payments for the remainder of such calendar month shall be made in cash as provided herein. 

iv.    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)(iv), the Company shall, in payment of the Holder Redemption Amount deliver to the Holder a number of shares of Common Stock equal to the
quotient of (such quotient of (x) and (y), the “Stock Payment Shares”) (x) the applicable Holder Redemption Amount and (y) the Stock Payment Price by not later than the applicable Holder Redemption Payment Date; provided,
that if the Holder has actually received Monthly Redemption Advance Shares, the number of Stock Payment Shares deliverable pursuant to the immediately preceding sentence shall be reduced (but not below zero) by the excess (if any) of the
Monthly Redemption Advance Shares actually received by the Holder over the aggregate number of Stock Payment Shares that 

  
 19 








 
were deliverable pursuant to this Section 4(a)(iv) for all other prior Holder Redemption Notices given during the same calendar month (such excess, as the Monthly Redemption Advance Shares
may be further reduced pursuant to the last sentence of Section 4(d), the “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. 
 v.    Notwithstanding the foregoing or any other provision to
the contrary contained herein, 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 Holder’s Pro Rata Share of the Dollar Volume Limitation, then the Company shall pay the portion of the Holder Redemption Amount that would be in excess of the Holder’s Pro Rata Share of the
Dollar Volume Limitation in cash. In addition, in the event that the aggregate number of Monthly Redemption Advance Shares or Stock Payment Shares to be delivered to the Holder pursuant to this Section 4(a) in would cause such Holder to
exceed the Beneficial Ownership Limitation, then, (I) the Holder shall provide written notice to the Company that such delivery of all or a portion of such Monthly Redemption Advance Shares or Stock Payment Shares would cause the Holder to
exceed the Beneficial Ownership Limitation, and (II) in addition to delivery of the number of Monthly Redemption Advance Shares or Stock Payment Shares that would not cause such Holder to exceed the Beneficial Ownership Limitation, as
applicable, the Company shall issue to the Holder only such number of Monthly Redemption Advance Shares or Stock Payment Shares that would not cause the Holder to exceed the Beneficial Ownership Limitation, and with respect to Stock Payment Shares,
pay to the Holder, in lieu of such number of Stock Payment Shares that would cause the Holder to exceed the Beneficial Ownership Limitation an amount in cash equal to the portion of the Holder Redemption Amount that would otherwise be payable in
respect of such excess number of Stock Payment Shares. 
 vi.    If there are any Available Advance
Shares remaining after all Holder Redemption Notices delivered during a particular calendar month have been satisfied in full, the Holder will, at its option, retain such Available Advance Shares in partial satisfaction of the obligation of the
Company to deliver Advance Shares in respect of the next month on which the Company elects for this Debenture to be Stock On or return such remaining number of Available Advance Shares to the Company. 

vii.    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. 

  
 20 








 b)    Voluntary Conversion. 

i.    Voluntary Conversion. Commencing on the Original Issue 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(i) and Section 4(j). 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 first (1st) Business Day immediately following 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. 

ii.    Conversion Price. The conversion price in effect on any Conversion Date shall be equal to
$4.56, subject to adjustment herein (the “Conversion Price”). 
 iii.    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 one (1) Trading Day after the date of the applicable Notice of Conversion
(the “Conversion Share Delivery Date”). 
 c)    Mandatory Conversion. If, at any
time after September 1, 2017, (i) the VWAP for Common Stock equals or exceeds two hundred fifty percent (250%) of the Conversion Price (the “Threshold Price”) for twenty (20) consecutive Trading Days (the
“Threshold Period”), and (ii) the Equity Conditions have been satisfied on each Trading Day during the Threshold Period and each of the ten (10) consecutive Trading Days 

  
 21 








 
immediately prior to the first (1st) day of the Threshold Period, then the Company shall have the option, within ten (10) Trading Days
after the end of any such Threshold Period, to deliver a written notice to the Holder (a “Mandatory Conversion Notice”) to cause the Holder to convert, pursuant to Section 4(b) hereof, a principal amount of this Debenture (a
“Mandatory Conversion”), during the thirty (30) Trading Day period after the Holder’s receipt of the Mandatory Conversion Notice (the “Mandatory Conversion Period”), equal to the lesser of (1) the
Holder’s Pro Rata Share of the Dollar Volume Limitation on the date of the Mandatory Conversion Notice and (2) the entire outstanding principal balance of this Debenture (including, for the avoidance of doubt, any original issue discount)
plus all accrued and unpaid interest thereon (such lesser amount, the “Mandatory Conversion Amount”); provided, however, if the Equity Conditions cease to be satisfied at any time during the Mandatory Conversion Period or the VWAP
for the Common Stock on any Trading Day following the last Trading Day of the Threshold Period (including during the Mandatory Conversion Period) is less than the Threshold Price, then the Holder shall be under no further obligation with respect to
such Mandatory Conversion. The Holder shall effect any Mandatory Conversion by delivering one or more Notices of Conversions pursuant to Section 4(b) at any time, and from time to time, during the applicable Mandatory Conversion Period, for
an aggregate principal amount equal to the Mandatory Conversion Amount. For the avoidance of doubt, the Company may deliver more than one Mandatory Conversion Notice during the term of this Debenture, provided, that it may not deliver a Mandatory
Conversion Notice during any Mandatory Conversion Period. For the further avoidance of doubt, nothing in this Section 4(c) shall be deemed to limit the Holder’s right to voluntarily convert all or any portion of this Debenture, at any
time, and from time to time, in accordance with Section 4(b), and the Holder may submit Notices of Conversion for a principal amount of this Debenture in excess of the Mandatory Conversion Amount during any Mandatory Conversion Period.
Concurrently with the delivery of any Mandatory Conversion Notice to the Holder hereunder, the Company shall publicly disclose its election to require the Mandatory Conversion of this Debenture by means of a Current Report on Form 8-K filed with the Commission. 
 d)    Delivery of Certificate for
Stock Payment Shares and Conversion Shares. The Company shall deliver any Debenture Shares required to be issued by the Company electronically through DTC without restrictive legends or trading restrictions of any kind not later than the
applicable Delivery Date; provided, that prior to the six (6) month anniversary of the Original Issue Date, in order for such Debenture Shares to be issued without restrictive legends, the Company shall be in compliance with the current public
information requirements of Rule 144. The Company shall, at its own expense, cause Company Counsel to issue any legal opinions required to issue Debenture Shares without any restrictive legends or trading restrictions of any kind, such legal opinion
to be substantially in the form of Annex C. If Conversion Shares or Stock Payment Shares, as the case may be, are not delivered to or as directed by the applicable Delivery Date, 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 Conversion Shares or Stock


  
 22 








 
Payment Shares, to rescind the applicable Notice of Conversion or Holder Redemption Notice, as the case may be. In addition to any other remedies of the Holder hereunder, in connection with any
Notice of Conversion, if the Company does not deliver the applicable Conversion Shares by the applicable Conversion Share Delivery Date, the Holder may, at its option, in connection with any conversion of this Debenture pursuant to Section
4(b), apply any Available Advance Shares to the satisfaction of the Company’s obligation to deliver the applicable Conversion Shares on the applicable Conversion Share Delivery Date. 

e)    Obligation Absolute; Partial Liquidated Damages. The Company’s obligations to issue and
deliver Debenture 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 Debenture 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 Debenture 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
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 Debenture Shares required to be issued hereunder in
accordance with the terms hereof. If the Company fails for any reason to deliver to the Holder Debenture Shares required to be issued pursuant to any provision of this Debenture by the second Trading Day following the applicable Delivery Date, 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, five dollars ($5) per Trading Day for each Trading
Day after the second Trading Day following such 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 Debenture
Shares required to be issued pursuant to any provision of this Debenture by the applicable Delivery Date more than twice in any twelve (12) month period, then such partial liquidated damages shall begin to accrue on the Delivery Date. Nothing
herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 7 hereof for the Company’s failure to deliver Debenture Shares within the


  
 23 








 
applicable 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. 

f)    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 Debenture Shares required to be issued pursuant to any provision of this Debenture by the applicable Delivery
Date, and if after such 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 Debenture Shares which the Holder was entitled to receive (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 Debenture Shares that the Holder was entitled to receive 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) deliver to the Holder the number of Debenture Shares that would have been issued if the Company had timely complied with its delivery requirements or, at the option of the Holder, if such Debenture Shares are Conversion
Shares or Stock Payment Shares, rescind the Notice of Conversion or Holder Redemption Notice, as applicable, at issue. For example, if the Holder purchases Common Stock having a total purchase price of eleven thousand dollars ($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
ten thousand dollars ($10,000) under clause (A) of the immediately preceding sentence, the Company shall be required to pay the Holder one thousand dollars ($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 Debenture Shares as required pursuant to the terms hereof. 

g)    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. 

h)    Transfer Taxes and Expenses. The issuance of Debenture 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 Debenture Shares. The Company shall pay all Transfer Agent fees required for processing of any issuance of


  
 24 








 
Debenture Shares and all fees to DTC (or another established clearing corporation performing similar functions) required for same-day electronic delivery
of Debenture Shares. 
 i)    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 Conversion Shares, Stock Payment Shares, Monthly Redemption Advance 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(i), 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(i) 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 Notice of Conversion or Holder Redemption Notice (at a time when this Debenture is Stock On) 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. In addition, the Holder may notify the Company that the issuance of any
Monthly Redemption Advance Shares would cause the Holder to exceed the Beneficial Ownership Limitation, in which case, the Company shall only issue to the Holder such number of shares of Common Stock that would not cause the Holder to exceed the
Beneficial Ownership (as determined by the Holder in accordance with this Section 4(i)). 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) 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(i), 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


  
 25 








 
shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.9% 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 Borrowers, may increase or decrease the Beneficial Ownership Limitation
provisions of this Section 4(i), provided that the Beneficial Ownership Limitation in no event exceeds 9.9% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock
pursuant to the terms of this Debenture and the Beneficial Ownership Limitation provisions of this Section 4(i) 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(i) 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. 

j)    Principal Market Regulation. The Company shall not issue any Debenture Shares if the issuance
thereof 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, including rules related to the aggregation of offerings under NASDAQ Listing Rule 5635(d), the “Exchange Cap”), except that such limitation shall not
apply to the extent that the Company (A) obtains the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of Debenture Shares in excess of such amount or (B) obtains a written opinion from
Company Counsel that such approval is not required, which opinion shall be reasonably satisfactory to the Holder. Until such approval or such written opinion is obtained, no Purchaser shall be issued Debenture Shares in an amount greater than the
product of (i) the Exchange Cap multiplied by (ii) the quotient of (A) the aggregate original principal amount of Debentures issued to such Purchaser pursuant to the Securities Purchase Agreement on the Closing Date divided by
(B) the aggregate original principal amount of all Debentures issued to the Purchasers pursuant to the Securities Purchase Agreement on the Closing Date (with respect to each Purchaser, the “Exchange Cap Allocation”). On the
Original Issue Date, the Holder’s Exchange Cap Allocation with respect to this Debenture is 4,269,522 shares of Common Stock. In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Debentures, the
transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation with respect to such portion of such Debentures so transferred, and the restrictions of the prior sentence shall apply to such transferee with respect
to the portion of the Exchange Cap Allocation so allocated to such transferee. Upon the satisfaction in full of a Purchaser’s Debentures, the difference (if any) between such holder’s Exchange Cap Allocation and the number of Debenture
Shares actually issued to such holder pursuant to such holder’s Debentures shall be allocated to the respective Exchange Cap Allocations of the remaining holders of Debentures on a pro rata basis in proportion to the relative outstanding
principal amounts of the Debentures then held by each such holder. In the event that the Company is prohibited from issuing Conversion Shares pursuant to Section 4(b) of this Debenture 

  
 26 








 
because of this Section 4(j) (the “Exchange Cap Shares”), the Company shall pay cash in exchange for the cancellation of such shares of Common Stock at a price equal to
the sum of (i) the product of (x) such number of Exchange Cap Shares and (y) the last closing sale price of the Common Stock on the Principal Market (as reported by Bloomberg) on the date the Holder delivers the applicable Notice of
Conversion with respect to such Exchange Cap Shares to the Company. 
 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)    Subsequent Equity Sales. If, at any time while this Debenture is outstanding, the Company or
any Subsidiary, as applicable, sells or grants any option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues (or announces any sale, grant or any option to purchase or other disposition), any Common Stock or
Common Stock Equivalents entitling any Person to acquire shares of Common Stock at an effective price per share that is lower than the then Conversion Price (such issuances, collectively, a “Dilutive Issuance”) (if the holder of the
Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per
share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is lower than the Conversion Price, such issuance shall be deemed to have occurred for less than the
Conversion Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced and only reduced to an amount equal to the product obtained by multiplying the Conversion Price by a fraction, the numerator of which is the number
of shares of Common Stock issued and outstanding immediately prior to the Dilutive Issuance plus the number of shares of Common Stock which the aggregate offering price for such Dilutive Issuance would purchase at the then Conversion Price,


  
 27 








 
and the denominator of which shall be the sum of the number of shares of Common Stock issued and outstanding immediately prior to the Dilutive Issuance plus the number of shares of Common Stock
so issued or issuable in connection with the Dilutive Issuance (such product, the “Base Conversion Price”). Such adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued. Notwithstanding the
foregoing, no adjustment will be made under this Section 5(b) in respect of an Exempt Issuance. If the Company enters into a Variable Rate Transaction, despite the prohibition set forth in the Purchase Agreement, the Company shall be deemed
to have issued Common Stock or Common Stock Equivalents at the lowest possible conversion price at which such securities may be converted or exercised. The Company shall notify the Holder in writing, no later than the Trading Day following the
issuance of any Common Stock or Common Stock Equivalents subject to this Section 5(b), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the
“Dilutive Issuance Notice”). For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 5(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to
receive a number of Conversion Shares based upon the Base Conversion Price on or after the date of such Dilutive Issuance, regardless of whether the Holder accurately refers to the Base Conversion Price in the Notice of Conversion. 

c)    Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 5(a)
above, if at any time the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase
Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock
acquirable upon complete conversion of this Debenture (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant,
issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent
that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or
beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in
the Holder exceeding the Beneficial Ownership Limitation). 
 d)    Pro Rata Distributions. During
such time as this Debenture is outstanding, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise
(including, without limitation, any distribution of cash, stock or other 

  
 28 








 
securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”),
at any time after the issuance of this Debenture, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of
shares of Common Stock acquirable upon complete exercise of this Debenture (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is
taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the
Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial
ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in
the Holder exceeding the Beneficial Ownership Limitation). 
 e)    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(i) or Section 4(j) 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(i) or Section 4(j) on the conversion of this
Debenture). For the purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one
(1) share of Common Stock in such Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate
Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any
conversion of this Debenture following such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing
all of the obligations of the Company under this Debenture and the other Transaction Documents (as defined in the Purchase Agreement) in accordance with the provisions of this Section 5(e) pursuant to written agreements in form and substance
reasonably satisfactory to the Holder and 

  
 29 








 
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. For the avoidance of doubt, nothing in this Section 5(e) shall be deemed implied consent to any Fundamental Transaction
otherwise prohibited by the Transaction Documents. 
 f)    Calculations. All calculations under
this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be
the sum of the number of shares of Common Stock (excluding any treasury shares of the Company) issued and outstanding. 

g)    Notice to the Holder. 

i.    Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any
provision of this Section 5, the Company shall promptly deliver to 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 Holder. If (A) the Company shall declare a dividend
(or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the
Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the
Common Stock, any 

  
 30 








 
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 filed with the Commission. 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.    Covenants. 

a)    As long as any portion of this Debenture remains outstanding, and unless the Holder shall have
otherwise given prior written consent, the Company shall not, and shall not permit any of the Subsidiaries to, directly or indirectly: 

i.    other than Permitted Indebtedness, enter into, create, incur, assume, guarantee or suffer to exist
any Indebtedness 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. For the avoidance of doubt, in
no event shall the Company become an obligor under, a guarantor of or otherwise liable for any Indebtedness or other obligations of Allenex or any direct or indirect Subsidiaries of Allenex (collectively, “Allenex Indebtedness”),
including without limitation, (A) under the term loan facility and credit facility with Danske Bank A/S, (B) any Indebtedness or obligations owed to SSP Primers AB, or (C) any Indebtedness or obligations owed to FastPartner AB, Midroc
AB, Xenella Holding AB and Mohammed Al Amoudi and the Affiliates of each of the foregoing (collectively, the “Allenex Vendors”) pursuant to the outstanding loans from the Allenex Vendors to Allenex; 

  
 31 








 ii.    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; 

iii.    make or hold any Investments, including, without limitation, making or holding any Investment in a
Subsidiary that is not a Guarantor, other than Permitted Investments; 
 iv.    other than Permitted
Dispositions, Dispose of any its assets, including, without limitation, any Disposition to a Subsidiary that is not a Guarantor, unless such Subsidiary immediately becomes a Guarantor; 

v.    amend its charter documents, including, without limitation, its certificate of incorporation and
bylaws, in any manner that adversely affects any rights of the Holder under the Transaction Documents in any material respect; 

vi.    merge, dissolve, liquidate, consolidate with or into another Person, or otherwise suffer or permit a
Change of Control Transaction or Fundamental Transaction; provided, however, that the Company may, without the Holder’s consent, cause any Domestic Subsidiary to be merged with and into the Company or another Domestic Subsidiary,
provided such surviving Domestic Subsidiary, if not already a party to the Security Agreement, promptly executes a joinder thereto, provided, further, in no event shall any such merger result in the Company or any Domestic Subsidiary assuming or
otherwise becoming liable for any Allenex Indebtedness; and provided further, that the Company may, without the Holder’s consent, enter into a Change of Control Transaction or Fundamental Transaction pursuant to which the Company is
acquired (or deemed acquired) by an un-Affiliated third party (a) that is a corporation organized or existing under the laws of the state of Delaware or the laws of the United States, any state thereof or
the District of Columbia and has its principal place of business in the United States, (b) that has a market capitalization, as of the date of the closing of such Change of Control Transaction or Fundamental Transaction, as applicable, equal to
or greater than the market capitalization of the Company as of immediately prior to such Change of Control Transaction or Fundamental Transaction, as applicable, (c) whose primary shares are publicly traded on the NYSE MKT, the Nasdaq Global
Select Market, the Nasdaq Global Market, the Nasdaq Capital Market or the New York Stock Exchange, in any case, as of the closing of such Change of Control Transaction or Fundamental Transaction, as applicable, (d) the Company and the successor
corporation comply with Section 5(e) of this Debenture, (e) immediately after giving effect to such transaction, no Event of Default, and no event that, after notice or lapse of time or both, would become an Event of Default, shall have
occurred and be continuing, (f) the successor corporation shall be in compliance with Section 6(a)(i) and Section 6(a)(ii) immediately after giving effect to 

  
 32 








 
such transaction and the other terms and conditions of the Transaction Documents, (g) the shares of common stock of the successor shall have similar or greater average daily dollar trading
volume as the average daily dollar trading volume for shares of Common Stock of the Company in the six (6) months prior to the transaction, (h) the successor corporation, immediately after giving effect to such transaction, shall have a
substantially similar, or superior, financial condition as the Company’s financial condition immediately prior to such transaction, including, by way of example, as to net assets, liabilities, and net income and (i) notwithstanding any
other provision of this Section 6(a)(vi), no transaction shall place the Holder in a worse credit risk situation, given the totality of the circumstances, than the Holder was in, considering the credit profile of the Company on the Original
Issue Date or immediately prior to the transaction, whichever credit profile was stronger. 

vii.    repay, repurchase or offer to repay, repurchase or otherwise acquire any of its Equity Interests
other than repurchases of Common Stock or Common Stock Equivalents of departing officers, directors and employees of the Company, provided that such repurchases shall not exceed an aggregate of $200,000 for all officers, directors and employees
during the term of this Debenture; 
 viii.    repay, repurchase or offer to repay, repurchase or
otherwise acquire any Indebtedness other than (i) this Debenture and (ii) regularly scheduled principal and interest payments under the terms of any Permitted Indebtedness, provided that any such payments of Permitted Indebtedness shall
not be permitted if, at such time, or after giving effect to such payment, any Event of Default exists or occurs and is continuing; 

ix.    pay dividends or distributions on any of its Equity Securities, except that any Subsidiary may,
directly or indirectly, pay any dividend or distribution to the Company; 
 x.    create any new
Subsidiary unless such Subsidiary is promptly added as a Guarantor and promptly executes a joinder to the Subsidiary Guaranty and Security Agreement; 

xi.    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); 
 xii.    maintain deposit accounts, or accounts holding
investment property, except (i) with respect to which the Agent has an Account Control Agreement, (ii) which hold a balance of no more than Five Hundred Thousand Dollars ($500,000), and (iii) for accounts of Foreign Subsidiaries in
existence on the Original Issue Date; or 

  
 33 








 xiii.    enter into any agreement with respect to any of the
foregoing. 
 b)    Blocked Account. The Company shall, at all times while this Debenture remains
outstanding, maintain on deposit in a segregated account of the Company at Comerica (the “Blocked Account”) an amount of unencumbered cash equal to $9,375,000. Such account shall be subject to an Account Control Agreement which
shall be in substantially the form of Comerica’s hard account agreement and otherwise reasonably acceptable to the Holder (the “Blocked Account Agreement”). 

c)    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, except that the Company shall not be permitted to issue any Disqualified Stock. 

d)    Gross Profit. With respect to each calculation date set forth below (each a
“Calculation Date”), Gross Profit for the twelve consecutive month period ended on such Calculation Date shall not be less than the “Gross Profit Target” set forth opposite such Calculation Date: 

 

					
	Calculation Date	  	Gross Profit Target	 
	March 31, 2017	  	$	17,000,000	 
	June 30, 2017	  	$	17,000,000	 
	September 30, 2017	  	$	17,500,000	 
	December 31, 2017	  	$	18,000,000	 
	March 31, 2018	  	$	18,000,000	 
	June 30, 2018	  	$	18,000,000	 
	September 30, 2018	  	$	18,000,000	 
	December 31, 2018	  	$	18,000,000	 
	March 31, 2019	  	$	18,000,000

	September 30, 2019	  	$	18,000,000	 
	December 31, 2019	  	$	18,000,000	 


  
 34 








 In the event of any breach of this Section 6(d) with respect to a specific
Calculation Date, the Company may cure such breach for such specific Calculation Date to the extent that: (1) the amount by which actual Gross Profit for such Calculation Date is less than the Gross Profit Target for such Calculation Date (the
“Gross Profit Shortfall”) does not exceed One Million Five Hundred Thousand Dollars ($1,500,000) and (2) by not later than fifty (50) days after such Calculation Date, the Company offers to redeem (and if such offer of
redemption is accepted by the Holder, promptly, but in any event not later than sixty (60) days after such Calculation Date, actually redeems) a portion of this Debenture equal to the Holder’s Pro Rata Share of an amount equal to 3x the
Gross Profit Shortfall for a redemption price equal to the Gross Profit Shortfall Redemption Price. Any offer to redeem a portion of this Debenture pursuant to this Section 6(d) shall also be made to the holders of the other outstanding Debentures.
For the avoidance of doubt, if the Gross Profit Shortfall for any Calculation Date exceeds One Million Five Hundred Thousand Dollars ($1,500,000) such breach cannot be cured and shall constitute an immediate Event of Default hereunder. For the
further avoidance of doubt, payment of the Gross Profit Shortfall Redemption Price with respect to a breach of this Section 6(d) for a specific Calculation Date shall only be deemed to cure the breach of this this Section
6(d) for that specific Calculation Date and shall not serve to cure any subsequent breach of this Section 6(d). With respect to each of the December 31, 2017, December 31, 2018, and December 31, 2019 calculation dates, in
the event of a breach of this Section 6(d), the Company shall publicly disclose Gross Profit within forty five (45) days thereafter, and in any event, prior to disclosing Gross Profit to the Holder.

ended March 31, 2018, Commercial Launch Milestone #2 shall be achieved for the fiscal quarter ended June 30, 2018, and Commercial Launch Milestone #3 shall be achieved for the fiscal quarter ended September 30, 2018; provided,
however, if any Commercial Launch Milestone has not been achieved in the corresponding fiscal quarter, it shall not be deemed an Event of Default hereunder to the extent that: (1) Commercial Launch Milestone #1 is achieved no later than the
fiscal quarter ended June 30, 2018, (2) Commercial Launch Milestone #2 is achieved no later than the fiscal quarter ended September 30, 2018, (3) Commercial Launch Milestone #3 is achieved no later than the fiscal quarter ended
December 31, 2018, (4) the Company offers to redeem (and if such offer of redemption is accepted by the Holder, promptly, but in any event not later than May 1, 2018, actually redeems) a portion of this Debenture equal to One Million Five
Hundred Thousand Dollars ($1,500,000) for a redemption price of One Million Six Hundred Twenty Thousand Dollars ($1,620,000), if the Commercial Launch Milestone #1 has not been achieved by March 31, 2018, (5) the Company offers to redeem (and
if such offer of redemption is accepted by the Holder, promptly, but in any event not later than August 1, 2018, actually redeems) a portion of this Debenture equal to Two Million Dollars ($2,000,000) for a redemption price of Two Million One
Hundred Sixty Thousand Dollars ($2,160,000), if the Commercial Launch Milestone #2 has not been achieved by June 30, 2018 and (6) the Company offers to redeem (and if such offer of redemption is accepted by the Holder, promptly, but in any
event not later than October 1, 2018, actually redeems) a portion of this Debenture equal to Three Million Dollars ($3,000,000) for a redemption price of Three Million Two Hundred Forty 

  
 35 








 
Thousand Dollars ($3,240,000), if the Commercial Launch Milestone #3 has not been achieved by September 30, 2018. Any offer to redeem a portion of this Debenture pursuant to this Section
6(e) shall also be made to the holders of the other outstanding Debentures. If the Company does not make any payment required by this Section 6(e), it shall be an immediate Event of Default hereunder. The Company shall publicly disclose each
Commercial Launch Milestone within five (5) Business Days of the achievement thereof by means of a Current Report Form 8-K filed with the Commission. 

f)    Compliance Certificate. The Company shall, within one Trading Day of the Company’s filing
of each Quarterly Report on Form 10-Q and each Annual Report on Form 10-K with the Commission (but in any event not later than 45 days after the last day of each
calendar quarter, except in the case of the calendar quarter ended December 31, 90 days thereafter), deliver to the Holder a compliance certificate executed by the Company’s chief executive officer or chief financial officer containing a
calculation of Gross Profit for the applicable calendar quarter, stating that no Events of Default have occurred since the date of the last compliance certificate (or, in the case of the initial compliance certificate, the Original Issue Date) and
certifying that no new Subsidiaries have been formed or acquired since the date of the prior compliance certificate (or, in the case of the initial compliance certificate, the Original Issue Date); provided, that notwithstanding the foregoing,
without the prior written consent of the Holder, such compliance certificate shall not contain any material, non-public information and shall be derived from the information publicly available in the
Company’s reports filed with the Commission or otherwise publicly available.

factoring arrangement beyond any grace period provided with respect thereto that (a) involves an obligation greater than Five Hundred Thousand Dollars ($500,000), whether such Indebtedness now exists or shall hereafter be created, and
(b) results in such Indebtedness becoming or being declared due and payable prior to the date on which it would otherwise become due and payable, in each case other than the obligations of (A) Allenex pursuant to its term loan facility and

for fifteen (15) Trading Days (which need not be consecutive) during any twelve (12) month period, or (c) the shares of Common Stock are suspended from trading or otherwise not listed or quoted for trading on a Trading Market for five
(5) consecutive Trading Days; provided, however, that for purposes of this subparagraph (viii), any day on which there is a general suspension of trading on the Principal Market shall be disregarded; 

ix.    the Company shall fail for any reason to deliver any Debenture Shares to a Holder on the applicable

(B) without limiting clause (A), Comerica notifies the Agent of its intention not to comply with the terms of the Blocked Account Agreement, or (C) the Company fails to comply, or notifies the Agent of its intention to not comply, with its
obligations under the Blocked Account Agreement; provided, however, with respect to clauses (A) and (B), it shall not be an Event of Default hereunder if (x) possession of the funds held in the Blocked Account are transferred to the Agent
or (y) the Company and the Agent enter into a new Account Control Agreement with a financial institution acceptable to Agent with respect to the funds held in the Blocked Account within ten (10) days after the occurrence of the failure or

xvi.    if any provision of the Security Agreement shall at any time for any reason be declared to be null
and void, or the validity or enforceability thereof shall 

  
 38

continuing, the outstanding principal amount of this Debenture, plus accrued but unpaid interest, liquidated damages and other amounts owing in respect thereof through the date of acceleration, shall become, at the Holder’s election,
immediately due and payable in cash at the Mandatory Default Amount; provided, that such acceleration shall be automatic, without any notice or other action of the Holder required, in respect of an Event of Default occurring pursuant to clause
(vi) of Section 7(a). For the avoidance of doubt, in no event shall the Mandatory Default Amount be payable in shares of Common Stock. Upon the payment in full of the Mandatory Default Amount in cash, 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 and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such acceleration may be rescinded and annulled by Holder at
any time prior to payment hereunder and the Holder shall have all rights as a holder of the Debenture until such time, if any, as the Holder receives full payment pursuant to this Section 7(b). No such rescission or annulment shall affect any
subsequent Event of Default or impair any right consequent thereon. 

Section 8.    Miscellaneous. 

a)    Notices. Any and all notices or other communications or deliveries to be provided by the
Holder hereunder, including, without limitation, any Holder Redemption 

  
 39 








 
Notice, shall be in writing and delivered personally, by facsimile, by email attachment, or sent by a nationally recognized overnight courier service, addressed to the Company, at the address set
forth above, or such other facsimile number, email address, or address as the Company may specify for such purposes by notice to the Holder delivered in accordance with this Section 8(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, by email attachment, or sent by a nationally recognized overnight courier service addressed to the Holder at the facsimile number or email
address or address of the Holder appearing on the books of the Company, or if no such facsimile number or email attachment or 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 at the facsimile
number or email attachment to the email address set forth on the signature pages attached hereto prior to 5:30 p.m. (local time in New York City, New York) (or such later time expressly specified elsewhere in this Debenture) on any date,
(ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the facsimile number or email attachment to the email address set forth on the signature pages attached hereto on a day that
is not a Trading Day or later than 5:30 p.m. (local time in New York City, New York) (or such later time expressly specified elsewhere in this Debenture) 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 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. 
 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


  
 40 








 
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. Any waiver by the Company
or the Holder of a breach of any provision of this Debenture shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Debenture. The failure of the Company or the
Holder to insist upon strict adherence to any term of this Debenture on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this
Debenture on any other occasion. Any waiver by the Company or the Holder must be in writing. Any provision of this Debenture may be waived by the Holders of at least 50.1% of the outstanding principal amount of Debentures, which waiver shall be
binding on all of the Holders of the Debentures and their successors and assigns. Any provision of this Debenture may be amended by a written instrument executed by the Company and the Holders of at least 50.1% of the outstanding principal amount of
Debentures, which amendment shall be binding on all of the Holders of the Debentures and their successors and assigns. 

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 

  
 41 








 
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 reasonably 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 pledged by the Company pursuant to the Security Agreement, dated as of the date hereof, between the Grantors (as defined therein) and the 

  
 42 








 
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. 

k)    Limitation of Liability. Neither Holder, Agent nor any Affiliate, officer, director, employee,
attorney, or agent of Holder or Agent shall have any liability with respect to, and the Company hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or
incurred by the Company in connection with, arising out of, or in any way related to, this Debenture or any of the other Transaction Documents, or any of the transactions contemplated by this Agreement or any of the other Transaction Documents. The
Company hereby waives, releases, and agrees not to sue Holder, Agent or any of Holder’s or Agent’s Affiliates, officers, directors, employees, attorneys, or agents for punitive damages in respect of any claim in connection with, arising
out of, or in any way related to, this Debenture or any of the other Transaction Documents, or any of the transactions contemplated by this Debenture or any of the other Transaction Documents. Notwithstanding the foregoing, nothing in this provision
shall be interpreted as waiving any right of the Company to any action based upon any material breach of the Transaction Documents or material violations by any Holder or Agent of state or federal securities laws or any conduct by any Holder which
constitutes fraud, gross negligence, willful misconduct or malfeasance).
