long as no Event of Default has occurred and is continuing, the aggregate unconverted and then outstanding principal amount of
this Debenture shall accrue interest from the Original Issue Date at the rate of eight percent (8%) per annum, compounded quarterly,
which accrued interest shall be added to the outstanding principal balance of this Debenture on the last day of each calendar
quarter (each such date, an “Interest Settlement Date”) (or, if such Interest Settlement Date is not a Business
Day, on the immediately succeeding Business Day) and shall thereafter itself, as part of the principal balance, accrue interest
at the rate set forth above, compounding quarterly on each Interest Settlement Date. All such accrued interest added to the principal
balance of this Debenture pursuant to the immediately preceding sentence shall be payable on the same terms and subject to the
same conditions set forth herein.


 


ii.         Notwithstanding
the foregoing clause (i), Company may provide Purchaser with written notice (each, a “Cash Pay Notice”) of
its intent to pay all or a portion of the interest which would otherwise accrue on the next succeeding Interest Settlement Date
in cash. Any Cash Pay Notice shall be delivered at least ten (10) Business Days prior to the applicable Interest Settlement Date

of Company regarding registration and transfers of this Debenture (the “Debenture Register”).


 




    	 	- 5 -	 



     


    

 


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


 


Section 3.          Registration
of Transfers and Exchanges.


 


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


 


b)         Investment Representations.

Agreement and may be transferred or exchanged only in compliance with the Purchase Agreement and applicable federal and state
securities laws and regulations.

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 Company
nor any such agent shall be affected by notice to the contrary.


 


Section 4.          Conversion.


 


a)         Voluntary Conversion.
This Debenture shall be convertible, in whole or in part, into shares of Common Stock at the option of Holder, at any time and
from time to time. Holder shall effect conversions by delivering to Company a Notice of Conversion, the form of which is attached
hereto as Annex A (each, a “Notice of Conversion”), specifying therein the principal amount of this
Debenture to be converted and, if Holder determines in its sole discretion to convert such accrued and unpaid interest (or a portion
thereof), the amount of accrued and unpaid interest thereon to be converted and the date on which such conversion shall be effected;
provided that Holder may only convert the portion of the accrued interest that corresponds to the principal being converted (such
date, the “Conversion Date”).  If no Conversion Date is specified in a Notice of Conversion, the
Conversion Date shall be the date that such Notice of Conversion is deemed delivered hereunder.  To effect conversions
hereunder, Holder shall not be required to physically surrender this Debenture to Company unless the entire principal amount of
this Debenture, plus all accrued and unpaid interest thereon, has been so converted or otherwise been repaid to Holder. Conversions
hereunder shall have the effect of lowering the outstanding principal amount of this Debenture in an amount equal to the principal
amount converted in such conversion.   Holder and Company shall maintain records showing the principal amount(s) converted
and the date of such conversion(s).   Company may deliver an objection to any Notice of Conversion within two (2) Business
Days of delivery of such Notice of Conversion.  In the event of any dispute or discrepancy, the records of Holder shall
be controlling and determinative in the absence of manifest error. Holder, and any assignee by acceptance of this Debenture,
acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Debenture,
the unpaid and unconverted principal amount of this Debenture may be less than the amount stated on the face hereof.


 


b)         Conversion
Price.  The Conversion Price in effect on any Conversion Date shall be equal to $0.16 and shall be subject to adjustment
as provided in Section 5 (the “Conversion Price”).


 




    	 	- 6 -	 



     


    

 


c)         Mechanics of
Conversion.


 


i.           Conversion
Shares Issuable Upon Conversion of Debenture.  The number of Conversion Shares issuable upon a conversion hereunder
shall be determined by the quotient obtained by dividing (x) the sum of (a) the outstanding principal amount of this Debenture
to be converted plus (b) any accrued and unpaid interest on the principal amount of this Debenture to be converted, by
(y) the Conversion Price.


 


ii.         Delivery
of Certificate Upon Conversion. Not later than three (3) Trading Days after each Conversion Date (the “Share Delivery
Date”), Company shall deliver, or cause to be delivered, to Holder a certificate or certificates representing the Conversion
Shares which, on a Legend Removal Qualification Event 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. If (i) there is an effective registration statement permitting the issuance of Conversion Shares
to or resale of the Conversion Shares by Holder or (ii) following the six month anniversary of the Closing Date, the Conversion
Shares are eligible for sale under Rule 144 without volume or manner-of-sale restrictions and as of such date Company is in compliance
with the current public information required under Rule 144 as to such Conversion Shares, Company shall deliver any certificate
or certificates required to be delivered by Company under this Section 4(c) by causing such certificates to be transmitted by
the Transfer Agent to the Holder by crediting the account of Holder’s designated brokerage firm with The Depository Trust
Company through its Deposit or Withdrawal at Custodian (“DWAC”) system if Company is then a participant in
such system or another established clearing corporation performing similar functions.


 


iii.         Failure
to Deliver Certificates.  If, in the case of any Notice of Conversion, such certificate or certificates are not
credited to the account of Holder’s broker with The Depository Trust Company through its DWAC system or another established
clearing corporation performing similar functions, if Company is then a participant in any such system, or delivered to or as
directed by Holder by the Share Delivery Date, Holder shall be entitled to elect by written notice to Company at any time on or
before such crediting or its receipt of such certificate or certificates, to rescind such Conversion, in which event Company shall
promptly return to Holder any original Debenture delivered to Company and Holder shall promptly return to Company the Common Stock
certificates (or any shares of Common Stock received electronically) issued to Holder pursuant to the rescinded Conversion Notice.


 




    	 	- 7 -	 



     


    

 


iv.         Obligation
Absolute; Partial Liquidated Damages.  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 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 Holder or any other Person of any obligation to Company (other than Holder’s obligations hereunder
with respect to the conversion, including the delivery of a Notice of Conversion) or any violation or alleged violation of law
by Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of Company
to Holder in connection with the issuance of such Conversion Shares; provided, however, that such delivery shall
not operate as a waiver by Company of any such action Company may have against Holder.  In the event Holder shall elect
to convert any or all of the outstanding principal amount hereof, Company may not refuse conversion based on any claim by Company
or any Affiliate thereof that Holder or anyone associated or affiliated with 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 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 Holder to the extent it obtains judgment.  In the absence of such injunction, Company shall issue Conversion Shares
or, if applicable, cash, upon a properly noticed conversion.  If Company fails when required hereunder for any reason
to deliver to Holder such certificate or certificates pursuant to Section 4(c)(ii) by the third Trading Day following the Share
Delivery Date, the Company shall pay to Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of principal
amount being converted, $5 per Trading Day (increasing to $10 per Trading Day on the fifth (5th) Trading Day after such liquidated
damages begin to accrue) for each Trading Day commencing on the third Trading Day after such Share Delivery Date until such certificates
are delivered or Holder rescinds such conversion. Nothing herein shall limit Holder’s right to pursue actual damages (provided
such damages may be reduced by the payments previously made hereunder) or declare an Event of Default pursuant to Section 8 hereof
for Company’s failure to deliver Conversion Shares within the period specified herein and 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 Holder from seeking to enforce damages
pursuant to any other Section hereof or under applicable law.


 


v.           Compensation
for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. In addition to any other rights available to Holder,
if Company fails for any reason to deliver to Holder such certificate or certificates by the Share Delivery Date pursuant to Section
4(c)(ii), and if after such Share Delivery Date Holder is required by its brokerage firm to purchase (in an open market transaction
or otherwise), or Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale
by Holder of the Conversion Shares which Holder was entitled to receive upon the conversion relating to such Share Delivery Date
(a “Buy-In”), then Company shall (A) pay in cash to Holder (in addition to any other remedies available to
or elected by Holder) the amount, if any, by which (x) 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 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 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 Holder the number of shares of Common Stock that would have been issued if
Company had timely complied with its delivery requirements under Section 4(c)(ii). For example, if 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, Company shall be required to pay Holder $1,000.
Holder shall provide Company written notice indicating the amounts payable to Holder in respect of the Buy-In and, upon request
of Company, evidence of the amount of such loss. Nothing herein shall limit 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 Company’s failure to timely deliver certificates representing shares of Common Stock upon conversion
of this Debenture as required pursuant to the terms hereof.


 




    	 	- 8 -	 



     


    

 


vi.         Reservation
of Shares Issuable Upon Conversion. Company covenants that it will at all times reserve and keep available out of its authorized
and unissued shares of Common Stock for the sole purpose of issuance upon conversion of this Debenture and payment of interest
on this Debenture, each as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons
other than Holder (and any other holder of the Debentures), not less than such aggregate number of shares of the Common Stock
as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments
and restrictions of Section 5) upon the conversion of the then outstanding principal amount of this Debenture and payment of interest
hereunder. 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 and, if the Registration Statement is then effective under the Securities Act, shall
be registered for public resale in accordance with such Registration Statement (subject to Holder’s compliance with its
obligations under the Registration Rights Agreement).


 


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 Holder would otherwise be entitled to purchase upon such conversion, Company shall at its election,
either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion
Price or round up to the next whole share.


 


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


 


Section 5.          Certain
Adjustments.


 


a)         Stock Dividends
and Stock Splits.  If 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 Company upon conversion of, or payment
of interest on, the Debentures), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines
(including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues,
in the event of a reclassification of shares of the Common Stock, any shares of capital stock of 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 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, Company or any Subsidiary, as applicable, sells or grants
any option to purchase or reprices or reduce the conversion or exercise price of any outstanding Securities, grants any right
to reprice, or otherwise disposes of or issues, 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, other than in connection with any
Common Stock Equivalents outstanding on the Original Issue Date (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 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 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 Company enters into a Variable Rate Transaction, despite the prohibition set forth in the
Purchase Agreement, 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. Company shall notify 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 Company provides a Dilutive Issuance
Notice pursuant to this Section 5(b), upon the occurrence of any Dilutive Issuance, 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 Holder
accurately refers to the Base Conversion Price in the Notice of Conversion.


 


c)          Subsequent
Rights Offerings.  If Company, at any time while this Debenture is outstanding, shall issue rights, options or
warrants to all holders of Common Stock (and not to Holder) entitling them to subscribe for or purchase shares of Common
Stock (the “Purchase Rights”), then, upon any conversion of this Debenture, Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights that Holder could have acquired if
Holder had held the number of Conversion Shares issued upon such conversion of this Debenture 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.


 


d)          Pro Rata
Distributions. If Company, at any time while this Debenture is outstanding, shall distribute to all holders of Common Stock
(and not to Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe
for or purchase any security other than the Common Stock (a “Distribution”), then, upon any conversion of this
Debenture, Holder shall be entitled to participate in such Distribution to the same extent that Holder would have participated
therein if Holder had held the number of Conversion Shares issued upon such conversion of this Debenture immediately before the
date on 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.

e)         Fundamental
Transaction. If, at any time while this Debenture is outstanding, (i) Company, directly or indirectly, in one or more related
transactions effects any merger or consolidation of Company with or into another Person, (ii) 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 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) Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization
or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted
into or exchanged for other securities, cash or property, (v) 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, 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, 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.  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 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 Holder shall be given the same choice as
to the Alternate Consideration it receives upon any conversion of this Debenture following such Fundamental Transaction.  Company
shall cause any successor entity in a Fundamental Transaction in which Company is not the survivor (the “Successor Entity”)
to assume in writing all of the obligations of Company under this Debenture and the other Transaction Documents (as defined in
the Purchase Agreement) in accordance with the provisions of this Section 5(d) pursuant to written agreements in form and substance
reasonably satisfactory to Holder and approved by Holder (without unreasonable delay) prior to such Fundamental Transaction and
shall, at the option of the holder of this Debenture, deliver to 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 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 “Company” shall refer instead to
the Successor Entity), and may exercise every right and power of Company and shall assume all of the obligations of Company under
this Debenture and the other Transaction Documents with the same effect as if such Successor Entity had been named as Company
herein.


 


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

f)         Notice

i.            Adjustment
to Conversion Price.  Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5, Company
shall within 10 calendar days of such adjustment deliver to 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) Company shall declare a dividend (or any other distribution in whatever form)
on the Common Stock, (B) Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C)
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 Company shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to which Company is a party, any sale or transfer of
all or substantially all of the assets of Company, or any compulsory share exchange whereby the Common Stock is converted into
other securities, cash or property or (E) Company shall authorize the voluntary or involuntary dissolution, liquidation or winding
up of the affairs of Company, then, in each case, 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 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 Company or any of its Subsidiaries, Company shall simultaneously file
such notice with the Commission pursuant to a Current Report on Form 8-K.   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 Holder. Subject to the provisions of this Section 6, at any time after either (i) the date
Company announces a Change of Control Transaction or (ii) the date Company or any Subsidiary enters into an agreement
providing for the sale of a material portion of their respective assets, Holder may deliver a notice to Company (a
“Holder Optional Redemption Notice” and the date such notice is deemed delivered hereunder, the
“Holder Optional Redemption Notice Date”) of its irrevocable election to cause Company 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 later of (i) the 5th Trading Day following the Holder Optional Redemption Notice Date or (ii) the date such applicable
transaction triggering such redemption right is consummated (such date, the “Holder Optional Redemption
Date” and such redemption, the “Holder Optional Redemption”). The Optional Redemption Amount is
payable in full on the Holder Optional Redemption Date. Any Holder Optional Redemption shall be applied ratably to all
Holders that submit a Holder Optional Redemption based on their (or their predecessor’s) initial purchases of
Debentures pursuant to the Purchase Agreement. Company hereby agrees to publicly disclose any Change of Control
Transaction or entry into an asset sale agreement which would trigger a redemption right hereunder within one Trading Day
from the date such agreement or transaction is entered into.

b)          Redemption
Procedure.  The payment of cash pursuant to a Holder Optional Redemption shall be payable on the applicable Holder
Optional Redemption Date.  If any portion of the payment pursuant to a Holder Optional Redemption shall not be paid
by Company by the Holder Optional Redemption Date, interest shall accrue on the aggregate amount payable by Company at the Default
Rate until such amount is paid in full.


 


Section 7.          Negative

b)          Remedies
Upon Event of Default. If any Event of Default has occurred and is 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,

described herein, Holder need not provide, and 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 Holder shall have all rights as a holder of the Debenture until such time,
if any, as 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.

which is absolute and unconditional, to pay the principal of, liquidated damages and accrued interest, as applicable, on this

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, County of New York (the “New York Courts”) unless otherwise specified therein. 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

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

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)          Waiver.  Any
waiver by Company or 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 Company or 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 Company or Holder must be in writing.


 


f)         Severability.  If
any provision of this Debenture is invalid, illegal or unenforceable, the balance of this Debenture shall remain in effect, and
if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to all other Persons and
circumstances.  If it shall be found that any interest or other amount deemed interest due hereunder violates the applicable
law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of
interest permitted under applicable law. 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 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 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 Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

Business Day.  Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day,

h)        Headings.  The
headings contained herein are for convenience only, do not constitute a part of this Debenture and shall not be deemed to
limit or affect any of the provisions hereof.
