Section
2.     Interest; Prepayment.


 


a)       Payment
of Interest in Cash or Kind; Notice; Interest Calculations and Late Fee.


 


i.       The
Company shall pay interest to the Holder on the aggregate unconverted and then outstanding principal amount of this Debenture
at the rate of 7.5% per annum, payable on each Conversion Date (as to interest accrued and payable, including pursuant to Section
2(b) below, on the principal amount subject to such conversion) and on the Maturity Date (each such date, an “Interest
Payment 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 or, at the Company’s option, in duly authorized, validly issued, fully paid and non-assessable
shares of Common Stock at the Interest Conversion Rate (the dollar amount to be paid in shares, the “Interest Share Amount”)
or a combination thereof; provided, however, that payment in shares of Common Stock may only occur if (i) there
is no existing Event of Default and no existing event which, with the passage of time or the giving of notice, would constitute
an Event of Default during the 5 Trading Days immediately prior to the Interest Payment Date (the “Interest Notice Period”),
(ii) the Company shall have given the Holder notice in accordance with the notice requirements set forth below and (iii) as to
such Interest Payment Date, the Company shall have delivered to the Holder’s account with The Depository Trust Company a
number of shares of Common Stock to be applied against such Interest Share Amount equal to the quotient of (x) the applicable
Interest Share Amount divided by (y) the lesser of the (i) then Conversion Price and (ii) the Interest Conversion Rate assuming
for such purposes that the Interest Payment Date is the Trading Day immediately prior to the commencement of the Interest Notice
Period (the “Interest Conversion Shares”).


 




    	6



    	 



    

 


ii.       Company’s
Election to Pay Interest in Cash or Kind. Subject to the terms and conditions herein, the decision whether to pay interest
hereunder in cash, shares of Common Stock or a combination thereof shall be at the sole discretion of the Company. Prior to the
commencement of any Interest Notice Period, the Company shall deliver to the Holder a written notice of its election to pay interest
hereunder on the applicable Interest Payment Date either in cash, shares of Common Stock or a combination thereof and the Interest
Share Amount as to the applicable Interest Payment Date, provided that the Company may indicate in such notice that the election
contained in such notice shall apply to future Interest Payment Dates until revised by a subsequent notice. During any Interest
Notice Period, the Company’s election (whether specific to an Interest Payment Date or continuous) shall be irrevocable
as to such Interest Payment Date. Subject to the aforementioned conditions, failure to timely deliver such written notice to the
Holder shall be deemed an election by the Company to pay the interest on such Interest Payment Date in cash. At any time the Company
delivers a notice to the Holder of its election to pay the interest in shares of Common Stock, the Company shall timely file a
prospectus supplement pursuant to Rule 424 disclosing such election. The aggregate number of shares of Common Stock otherwise
issuable to the Holder on an Interest Payment Date shall be reduced by the number of Interest Conversion Shares previously issued
to the Holder in connection with such Interest Payment Date.


 


iii.       Interest
shall be calculated on the basis of a 360-day year, consisting of twelve 30 calendar day periods, and shall accrue daily commencing
on the Original Issue Date until payment in full of the outstanding principal, together with all accrued and unpaid interest,
liquidated damages and other amounts which may become due hereunder, has been made. Payment of interest in shares of Common Stock
(other than the Interest Conversion Shares issued prior to an Interest Notice Period) shall otherwise occur pursuant to Section
4(c)(ii) herein and, solely for purposes of the payment of interest in shares, the Interest Payment Date shall be deemed the Conversion
Date. Interest hereunder will be paid to the Person in whose name this Debenture is registered on the records of the Company regarding
registration and transfers of this Debenture (the “Debenture Register”). Except as otherwise provided herein,
if at any time the Company pays interest partially in cash and partially in shares of Common Stock to the holders of the Debentures,
then such payment of cash shall be distributed ratably among the holders of the then-outstanding Debentures based on their (or
their predecessor’s) initial purchases of Debentures pursuant to the Purchase Agreement.


 


iv.       All
overdue accrued and unpaid interest to be paid hereunder shall entail a late fee at an interest rate equal to the lesser of 18%
per annum or the maximum rate permitted by applicable law (the “Late Fees”) which shall accrue daily from the
date such interest is due hereunder through and including the date of actual payment in full. Notwithstanding anything to the
contrary contained herein, if, on any Interest Payment Date the Company has elected to pay accrued interest in the form of Common
Stock but the Company is not permitted to pay accrued interest in Common Stock because it fails to satisfy the conditions for
payment in Common Stock set forth in Section 2(a) herein, then, at the option of the Holder, the Company, in lieu of delivering
either shares of Common Stock pursuant to this Section 2 or paying the regularly scheduled interest payment in cash, shall deliver,
within three (3) Trading Days of each applicable Interest Payment Date, an amount in cash equal to the product of (x) the number
of shares of Common Stock otherwise deliverable to the Holder in connection with the payment of interest due on such Interest
Payment Date multiplied by (y) the highest VWAP during the period commencing on the Interest Payment Date and ending on the Trading
Day prior to the date such payment is actually made. If any Interest Conversion Shares are issued to the Holder in connection
with an Interest Payment Date and are not applied against an Interest Share Amount, then the Holder shall promptly return such
excess shares to the Company.


 




    	7



    	 



    

 


b)       Interest
Make Whole. In the event that this Debenture is converted or redeemed (including via An Event of Default) prior to the Maturity
Date, the Company shall pay to the Holder, in addition to any other amounts then owed, in cash upon such conversion or redemption,
an amount in interest equal to the amount of interest that would otherwise have been payable if this Debenture had been held until
the Maturity Date.


 


c)       Prepayment.
Except as otherwise set forth in this Debenture, the Company may not prepay any portion of the principal amount of this Debenture
without the prior written consent of the Holder.


 


Section
3.     Registration of Transfers and Exchanges.


 


a)       Different
Denominations. This Debenture is exchangeable for an equal aggregate principal amount of Debenture of different authorized
denominations, as requested by the Holder surrendering the same. No service charge will be payable for such registration of transfer
or exchange.


 


b)       Investment
Representations. This Debenture has been issued subject to certain investment representations of the original Holder set forth
in the Purchase Agreement and may be transferred or exchanged only in compliance with the Purchase Agreement and applicable federal
and state securities laws and regulations.


 


c)       Reliance
on Debenture Register. Prior to due presentment for transfer to the Company of this Debenture, the Company and any agent of
the Company may treat the Person in whose name this Debenture is duly registered on the Debenture Register as the owner hereof
for the purpose of receiving payment as herein provided and for all other purposes, whether or not this Debenture is overdue,
and neither the Company nor any such agent shall be affected by notice to the contrary.

Section
4.     Conversion.


 


a)       Voluntary
Conversion. At any time after December 15, 2017 until this Debenture is no longer outstanding, this Debenture shall be convertible,
in whole or in part, into shares of Common Stock at the option of the Holder, at any time and from time to time (subject to the
conversion limitations set forth in Section 4(d) hereof). The Holder shall effect conversions by delivering to the Company a Notice
of Conversion, the form of which is attached hereto as Annex A (each, a “Notice of Conversion”), specifying
therein the principal amount of this Debenture to be converted, accrued but unpaid interest thereon (whether paid in cash or Interest
Conversion Shares) and the date on which such conversion shall be effected (such date, the “Conversion Date”).
If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion
is deemed delivered hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee (or other
type of guarantee or notarization) of any Notice of Conversion form be required. To effect conversions hereunder, the Holder shall
not be required to physically surrender this Debenture to the Company unless the entire principal amount of this Debenture, plus
all accrued and unpaid interest thereon, has been so converted. Conversions hereunder shall have the effect of lowering the outstanding
principal amount of this Debenture in an amount equal to the applicable conversion. The Holder and the Company shall maintain
records showing the principal amount(s) converted and the date of such conversion(s). The Company may deliver an objection to
any Notice of Conversion within one (1) Business Day of delivery of such Notice of Conversion. The Holder, and any assignee
by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion
of a portion of this Debenture, the unpaid and unconverted principal amount of this Debenture may be less than the amount stated
on the face hereof.


 


b)       Conversion
Price; Alternate Conversion Price.


 


i.       Conversion
Price. The conversion price in effect on any Conversion Date shall be equal to $0.20, subject to adjustment herein
(the “Initial Conversion Price”); provided after December 15, 2017 the Conversion Price shall equal the lesser
of (A) the Initial Conversion Price and (B) 60% of the lowest trading prices of the Common Stock on the Trading Market in the
ten (10) Trading Days prior to the date of conversion (the “Alternate Conversion Price”).


 


ii.       Alternate
Conversion Price Upon an Event of Default. At any time after the occurrence of an Event of Default which has not been cured
within 10 Trading Days (regardless of whether such Event of Default occurs prior to December 15, 2017), the Holder may, at the
Holder’s option, convert the outstanding Principal Amount plus any liquidated damages into shares of Common Stock at price
per share equal to 55% of the lowest trading price for the thirty (30) Trading Days immediately prior to date of conversion (the
“Event of Default Conversion Price”, and together with the Initial Conversion Price and the Alternate Conversion
Price, the “Conversion Price”).


 




    	9



    	 



    

 


c)     Mechanics of Conversion.




 


i.       Conversion
Shares Issuable Upon Conversion of Principal Amount. The number of Conversion Shares issuable upon a conversion hereunder
shall be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Debenture to be converted
by (y) the Conversion Price.


 


ii.       Delivery
of Conversion Shares Upon Conversion. Not later than the earlier of (i) three (3) Trading Days and (ii) the number of Trading
Days comprising the Standard Settlement Period (as defined below) after each Conversion Date (the “Share Delivery Date”),
the Company shall deliver, or cause to be delivered, to the Holder (A) the Conversion Shares which, on or after the six month
anniversary of the Original Issue Date, shall be free of restrictive legends and trading restrictions (other than those which
may then be required by the Purchase Agreement) representing the number of Conversion Shares being acquired upon the conversion
of this Debenture (including, if the Company has given continuous notice pursuant to Section 2(b) for payment of interest in shares
of Common Stock at least 20 Trading Days prior to the date on which the Notice of Conversion is delivered to the Company, shares
of Common Stock representing the payment of accrued interest otherwise determined pursuant to Section 2(a) but assuming that the
Interest Notice Period is the 20 Trading Days period immediately prior to the date on which the Notice of Conversion is delivered
to the Company and excluding for such issuance the condition that the Company deliver Interest Conversion Shares as to such interest
payment prior to the commencement of the Interest Notice Period) and (B) a bank check in the amount of accrued and unpaid interest
(if the Company has elected or is required to pay accrued interest in cash). On or after the six month anniversary of the Original
Issue Date the Company shall deliver any Conversion Shares required to be delivered by the Company under this Section 4(c) electronically
through the Depository Trust Company or another established clearing corporation performing similar functions. As used herein,
“Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on
the Company’s primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice
of Conversion.


 


iii.       Failure
to Deliver Conversion Shares. If, in the case of any Notice of Conversion, such Conversion Shares are not delivered to or
as directed by the applicable Holder by the Share Delivery Date, the Holder shall be entitled to elect by written notice to the
Company at any time on or before its receipt of such Conversion Shares, to rescind such Conversion, in which event the Company
shall promptly return to the Holder any original Debenture delivered to the Company and the Holder shall promptly return to the
Company the Conversion Shares issued to such Holder pursuant to the rescinded Conversion Notice.


 




    	10



    	 



    

 


iv.       Obligation
Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion
of this Debenture in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by
the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against
any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach
or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of
law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation
of the Company to the Holder in connection with the issuance of such Conversion Shares; provided, however, that
such delivery shall not operate as a waiver by the Company of any such action the Company may have against the Holder. In the
event the Holder of this Debenture shall elect to convert any or all of the outstanding principal amount hereof, the Company may
not refuse conversion based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in
any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and
or enjoining conversion of all or part of this Debenture shall have been sought and obtained, and the Company posts a surety bond
for the benefit of the Holder in the amount of 150% of the outstanding principal amount of this Debenture, which is subject to
the injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and
the proceeds of which shall be payable to the Holder to the extent it obtains judgment. In the absence of such injunction, the
Company shall issue Conversion Shares or, if applicable, cash, upon a properly noticed conversion. If the Company fails for any
reason to deliver to the Holder such certificate or certificates pursuant to Section 4(c)(ii) by the Share Delivery Date, the
Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of principal amount being
converted, $10 per Trading Day (increasing to $20 per Trading Day on the fifth (5th) Trading Day after such liquidated
damages begin to accrue) for each Trading Day after such Share Delivery Date until such certificates are delivered or Holder rescinds
such conversion. Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant
to Section 8 hereof for the Company’s failure to deliver Conversion Shares within the period specified herein and the Holder
shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree
of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to
enforce damages pursuant to any other Section hereof or under applicable law.


 




    	11



    	 



    

 


v.       Compensation
for Buy-In on Failure to Timely Deliver Conversion Shares Upon Conversion. In addition to any other rights available to the
Holder, if the Company fails for any reason to deliver to the Holder such Conversion Shares by the Share Delivery Date pursuant
to Section 4(c)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase (in an open
market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver
in satisfaction of a sale by the Holder of the Conversion Shares which the Holder was entitled to receive upon the conversion
relating to such Share Delivery Date (a “Buy-In”), then the Company shall (A) pay in cash to the Holder (in
addition to any other remedies available to or elected by the Holder) the amount, if any, by which (x) the Holder’s total
purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the aggregate
number of shares of Common Stock that the Holder was entitled to receive from the conversion at issue multiplied by (2) the actual
sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions)
and (B) at the option of the Holder, either reissue (if surrendered) this Debenture in a principal amount equal to the principal
amount of the attempted conversion (in which case such conversion shall be deemed rescinded) or deliver to the Holder the number
of shares of Common Stock that would have been issued if the Company had timely complied with its delivery requirements under
Section 4(c)(ii). For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In
with respect to an attempted conversion of this Debenture with respect to which the actual sale price of the Conversion Shares
(including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately
preceding sentence, the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice
indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount
of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law
or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s
failure to timely deliver Conversion Shares upon conversion of this Debenture as required pursuant to the terms hereof.


 


vi.       Reservation
of Shares Issuable Upon Conversion. The Company covenants that it will at all times reserve and keep available out of its
authorized and unissued shares of Common Stock at least a number of shares equal to the Required Minimum (as defined in the Purchase
Agreement). The Company covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized,
validly issued, fully paid and nonassessable.


 


vii.       Fractional
Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Debenture.
As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such conversion, the Company shall
at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied
by the Conversion Price or round up to the next whole share.

viii.       Transfer
Taxes and Expenses. The issuance of Conversion Shares on conversion of this Debenture shall be made without charge to the
Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such Conversion
Shares, provided that, the Company shall not be required to pay any tax that may be payable in respect of any transfer involved
in the issuance and delivery of any such Conversion Shares upon conversion in a name other than that of the Holder of this Debenture
so converted and the Company shall not be required to issue or deliver such Conversion Shares unless or until the Person or Persons
requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction
of the Company that such tax has been paid. The Company shall pay all Transfer Agent fees required for same-day processing of
any Notice of Conversion and all fees to the Depository Trust Company (or another established clearing corporation performing
similar functions) required for same-day electronic delivery of the Conversion Shares.


 


d)       Holder’s
Conversion Limitations. The Company shall not effect any conversion of this Debenture, and a Holder shall not have the right
to convert any portion of this Debenture, to the extent that after giving effect to the conversion set forth on the applicable
Notice of Conversion, the Holder (together with the Holder’s Affiliates, and any Persons acting as a group together with
the Holder or any of the Holder’s Affiliates) would beneficially own in excess of the Beneficial Ownership Limitation (as
defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder
and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of this Debenture with respect
to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i)
conversion of the remaining, unconverted principal amount of this Debenture beneficially owned by the Holder or any of its Affiliates
and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a
limitation on conversion or exercise analogous to the limitation contained herein (including, without limitation, any other Debentures
or the Warrants) beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for
purposes of this Section 4(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and
the rules and regulations promulgated thereunder. To the extent that the limitation contained in this Section 4(d) applies, the
determination of whether this Debenture is convertible (in relation to other securities owned by the Holder together with any
Affiliates) and of which principal amount of this Debenture is convertible shall be in the sole discretion of the Holder, and
the submission of a Notice of Conversion shall be deemed to be the Holder’s determination of whether this Debenture may
be converted (in relation to other securities owned by the Holder together with any Affiliates) and which principal amount of
this Debenture is convertible, in each case subject to the Beneficial Ownership Limitation. To ensure compliance with this restriction,
the Holder will be deemed to represent to the Company each time it delivers a Notice of Conversion that such Notice of Conversion
has not violated the restrictions set forth in this paragraph and the Company shall have no obligation to verify or confirm the
accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined
in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this
Section 4(d), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding
shares of Common Stock as stated in the most recent of the following: (i) the Company’s most recent periodic or annual report
filed with the Commission, as the case may be, (ii) a more recent public announcement by the Company, or (iii) a more recent written
notice by the Company or the Company’s transfer agent setting forth the number of shares of Common Stock outstanding. Upon
the written or oral request of a Holder, the Company shall within two Trading Days confirm orally and in writing to the Holder
the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be
determined after giving effect to the conversion or exercise of securities of the Company, including this Debenture, by the Holder
or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial
Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving
effect to the issuance of shares of Common Stock issuable upon conversion of this Debenture held by the Holder. The Holder, upon
notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 4(d), provided
that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately
after giving effect to the issuance of shares of Common Stock upon conversion of this Debenture held by the Holder and the Beneficial
Ownership Limitation provisions of this Section 4(d) shall continue to apply. Any increase in the Beneficial Ownership Limitation
will not be effective until the 61st day after such notice is delivered to the Company. The Beneficial Ownership Limitation
provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms
of this Section 4(d) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended
Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect
to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Debenture.

Section
5.     Certain Adjustments.


 


a)       Stock
Dividends and Stock Splits. If the Company, at any time while this Debenture is outstanding: (i) pays a stock dividend or
otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock
Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon conversion
of, or payment of interest on, the 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 Initial Conversion Price (such lower price,
the “Base Conversion Price” and 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 Initial Conversion Price, such issuance shall be deemed to have occurred for less than the Initial
Conversion Price on such date of the Dilutive Issuance), then the Initial Conversion Price shall be reduced to equal 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 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 conversion of this Debenture (without regard to any limitations on conversion hereof, including
without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution,
or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the
participation in such Distribution (provided, however, to the extent that the Holder’s right to participate
in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be
entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a
result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of
the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).


 




    	15



    	 



    

 


e)       Fundamental
Transaction. If, at any time while this Debenture is outstanding, (i) the Company, directly or indirectly, in one or more
related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company, directly
or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of
the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is
effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in
one or more related transactions consummates a stock or share purchase agreement or other business combination (including, without
limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person
acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person
or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such stock or share
purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent
conversion of this Debenture, the Holder shall have the right to receive, for each Conversion Share that would have been issuable
upon such conversion immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in
Section 4(d) on the conversion of this Debenture), the number of shares of Common Stock of the successor or acquiring corporation
or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Debenture
is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 4(d) on the conversion
of this Debenture). For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted
to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) share of
Common Stock in such Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate Consideration
in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of
Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the
Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Debenture following
such Fundamental Transaction. The Company shall cause any successor entity in a Fundamental Transaction in which the Company is
not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under
this Debenture and the other Transaction Documents (as defined in the Purchase Agreement) in accordance with the provisions of
this Section 5(e) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the
Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the holder of this Debenture,
deliver to the Holder in exchange for this Debenture a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Debenture which is convertible for a corresponding number of shares of capital stock of
such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon conversion
of this Debenture (without regard to any limitations on the conversion of this Debenture) prior to such Fundamental Transaction,
and with a conversion price which applies the conversion price hereunder to such shares of capital stock (but taking into account
the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such shares of capital
stock, such number of shares of capital stock and such conversion price being for the purpose of protecting the economic value
of this Debenture immediately prior to the consummation of such Fundamental Transaction), and which is reasonably satisfactory
in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed
to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Debenture
and the other Transaction Documents referring to the “Company” shall refer instead to the Successor Entity), and may
exercise every right and power of the Company and shall assume all of the obligations of the Company under this Debenture and
the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company herein.

f)       Calculations.
All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be.
For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall
be the sum of the number of shares of Common Stock (excluding any treasury shares of the Company) issued and outstanding.


 


g)       Notice
to the Holder.


 


i.       Adjustment
to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, the Company shall
promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement
of the facts requiring such adjustment.


 


ii.       Notice
to Allow Conversion by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on
the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C)
the Company shall authorize the granting to all holders of the Common Stock of rights or warrants to subscribe for or purchase
any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required
in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any
sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common
Stock is converted into other securities, cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution,
liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Debenture, and shall cause to be delivered to the Holder at its last
address as it shall appear upon the Debenture Register, at least twenty (20) calendar days prior to the applicable record or effective
date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record
to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date
as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common
Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect
the validity of the corporate action required to be specified in such notice. To the extent that any notice provided hereunder
constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall
simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall remain entitled
to convert this Debenture during the 20-day period commencing on the date of such notice through the effective date of the event
triggering such notice except as may otherwise be expressly set forth herein.

Section
6.     Redemption.


 


a)       Optional
Redemption at Election of Company. Subject to the provisions of this Section 6(a), at any time after the Original Issue Date,
the Company may deliver a notice to the Holder (an “Optional Redemption Notice” and the date such notice is
deemed delivered hereunder, the “Optional Redemption Notice Date”) of its irrevocable election to redeem some
or all of the then outstanding principal amount of this Debenture for cash in an amount equal to the Optional Redemption Amount
on the 5th Trading Day following the Optional Redemption Notice Date (such date, the “Optional Redemption
Date”, such 5 Trading Day period, the “Optional Redemption Period” and such redemption, the “Optional
Redemption”). The Optional Redemption Amount is payable in full on the Optional Redemption Date. The Company may only
effect an Optional Redemption if there is no existing Event of Default and no existing event which, with the passage of time or
the giving of notice, would constitute an Event of Default, during the Optional Redemption period. If such condition shall cease
to be satisfied at any time during the Optional Redemption Period, then the Holder may elect to nullify the Optional Redemption
Notice by notice to the Company within 3 Trading Days after the first day on which any such condition has not been met in which
case the Optional Redemption Notice shall be null and void, ab initio. The Company covenants and agrees that it will honor
all Notices of Conversion tendered from the time of delivery of the Optional Redemption Notice through the date all amounts owing
thereon are due and paid in full. The Company’s determination to pay an Optional Redemption in cash shall be applied ratably
to all of the holders of the then outstanding Debentures based on their (or their predecessor’s) initial purchases of Debentures
pursuant to the Purchase Agreement.


 


b)       Optional
Redemption at Election of Holder. From the date hereof until such time as this Debenture is no longer outstanding, if the
Company raises cash proceeds from an equity or debt financing, the Company shall immediately provide notice of such financing
to the Holder, including the gross proceeds of such financing. Thereafter, the Holder may deliver a notice to the Company (a “Holder
Redemption Notice” and the date such notice is deemed delivered hereunder, the “Holder Redemption Notice Date”)
of its irrevocable election to require the Company to redeem some or all of the then outstanding principal amount of this Debenture
for cash in an amount up to the Holder Redemption Amount on the 5th Trading Day following the Holder Redemption Notice
Date (such date, the “Holder Redemption Date”, such 5 Trading Day period, the “Holder Redemption Period”
and such redemption, the “Holder Redemption”). The Holder Redemption Amount is payable in full on the Holder
Redemption Date. Notwithstanding the foregoing, the Company shall be permitted to raise an aggregate of $500,000 in one or more
equity or debt financings before the Holder shall be permitted to require the Company to redeem its Debenture in accordance with
this Section 6(b).


 


c)       Redemption
Procedure. The payment of cash pursuant to an Optional Redemption or Holder Redemption shall be payable on the Optional Redemption
Date or Holder Redemption Date, as applicable. If any portion of the payment pursuant to an Optional Redemption or Holder Redemption
shall not be paid by the Company by the applicable due date, interest shall accrue thereon at an interest rate equal to the lesser
of 18% per annum or the maximum rate permitted by applicable law until such amount is paid in full. Notwithstanding anything herein
contained to the contrary, if any portion of the Optional Redemption Amount or Holder Redemption Amount remains unpaid after such
date, the Holder may elect, by written notice to the Company given at any time thereafter, to invalidate such Optional Redemption
or Holder Redemption, ab initio, and, with respect to the Company’s failure to honor the Optional Redemption, the
Company shall have no further right to exercise such Optional Redemption. The Holder may elect to convert the outstanding principal
amount of the Debenture pursuant to Section 4 prior to actual payment in cash for any redemption under this Section 6 by the delivery
of a Notice of Conversion to the Company.

repurchase or offer to repay, repurchase or otherwise acquire any Indebtedness, other than the Debenture, other than regularly

any assets of the Company or any domestic Subsidiary to a third party (other than in the ordinary course of business);

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);


 


j)       authorize,
create, modify or amend any now-existing or future-created class of equity, including series of common stock other than the Common
Stock or preferred stock of the Company; or

of Default” means, wherever used herein, any of the following events (whatever the reason for such event and whether
such event shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any
court, or any order, rule or regulation of any administrative or governmental body):


 


i.       any
default in the payment of (A) the principal amount of the Debenture or (B) interest, liquidated damages and other amounts owing

sent by the Holder to the Company and (B) 10 Trading Days after the Company has become or should have become aware of such failure;


 


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


 


iv.       any
representation or warranty made in this Debenture, any other Transaction Documents, any written statement pursuant hereto or thereto
or any other report, financial statement or certificate made or delivered to the Holder shall be untrue or incorrect in any material
respect as of the date when made or deemed made;


 


v.       the
Company or any Significant Subsidiary (as such term is defined in Rule 1-02(w) of Regulation S-X) shall be subject to a Bankruptcy
Event;


 


vi.       the

listing or quotation for trading thereon within five Trading Days;


 


viii.       the

b)       Remedies
Upon Event of Default. If any Event of Default occurs, 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. Commencing 5 days after the
occurrence of any Event of Default that results in the eventual acceleration of this Debenture, the interest rate on this Debenture
shall accrue at an interest rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. Upon
the payment in full of the Mandatory Default Amount, the Holder shall promptly surrender this Debenture to or as directed by the
Company. In connection with such acceleration described herein, the Holder need not provide, and the Company hereby waives, any
presentment, demand, protest or other notice of any kind, and the Holder may immediately 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 8(b). No such rescission
or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

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. This Debenture ranks pari passu with all other Debentures now or hereafter issued under the
terms set forth herein.


 


c)       Lost
or Mutilated Debenture. If this Debenture shall be mutilated, lost, stolen or destroyed, the Company shall execute and deliver,
in exchange and substitution for and upon cancellation of a mutilated Debenture, or in lieu of or in substitution for a lost,

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

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

    	23



    	 



    

 


e)       Waiver;
Amendment. 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 Holder, which waiver shall be binding on all successors and assigns. Any provision of this Debenture
may be amended by a written instrument executed by the Company and the Holder, which amendment shall be binding on all 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 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 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.


 




    	24



    	 



    

 


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 all assets of the Company and each Subsidiary
pursuant to the Security Agreement, dated as of May __, 2017 between the Company, the Subsidiaries of the Company and the Secured
Parties (as defined therein).


 


Section
11.     Disclosure. Upon receipt or delivery by the Company of any notice in accordance with the terms of this Debenture, unless
the Company has in good faith determined that the matters relating to such notice do not constitute material, nonpublic information
relating to the Company or its Subsidiaries, the Company shall within two (2) Business Days after such receipt or delivery publicly
disclose such material, nonpublic information on a Current Report on Form 8-K or otherwise. In the event that the Company believes
that a notice contains material, non-public information relating to the Company or its Subsidiaries, the Company so shall indicate
to the Holder contemporaneously with delivery of such notice, and in the absence of any such indication, the Holder shall be allowed
to presume that all matters relating to such notice do not constitute material, nonpublic information relating to the Company
or its Subsidiaries.
