in any manner impair the exercise of any such right. The consent of the Major Investors may be satisfied by a written instrument
signed, in the case of an amendment, by the Company and the Major Investors holding at least a majority in interest of the Debt
Securities then outstanding.


 


(g)          Section
5.18 of the Purchase Agreement is hereby amended and restated in its entirety as follows:


 


5.18       Independent Nature of Purchasers’
Obligations and Rights. The obligations of each Purchaser under the Transaction Documents are several and not joint with the
obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of
the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document,
and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as, and the Company
acknowledges that the Purchasers do not so constitute, a partnership, an association, a joint venture or any other kind of group
or entity, or create a presumption that the Purchasers are in any way acting in concert or as a group or entity with respect to
such obligations or the transactions contemplated by the Transaction Documents or any matters, and the Company acknowledges that
the Purchasers are not acting in concert or as a group, and the Company shall not assert any such claim with respect to such obligations
or the transactions contemplated by the Transaction Documents. The decision of each Purchaser to purchase Securities pursuant to
the Transaction Documents has been made by such Purchaser independently of any other Purchaser. Each Purchaser acknowledges that
no other Purchaser has acted as agent for such Purchaser in connection with such Purchaser making its investment hereunder and
that no other Purchaser will be acting as agent of such Purchaser in connection with monitoring such Purchaser’s investment
in the Securities. The Company and each Purchaser confirms that each Purchaser has independently participated with the Company
and its Subsidiaries in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors.
Each Purchaser shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising
out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined
as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel
in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each Purchaser and
its respective counsel have chosen to communicate with the Company through GP. GP does not represent the Purchasers other than
Broadfin. EGS does not represent the Purchasers other than Sabby. The Company has elected to provide all Purchasers with the same
terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any
of the Purchasers. The use of a single agreement to effectuate the purchase and sale of the Securities contemplated hereby was
solely in the control of the Company, not the action or decision of any Purchaser, and was done solely for the convenience of the
Company and its Subsidiaries and not because it was required or requested to do so by any Purchaser. It is expressly understood
and agreed that each provision contained in this Agreement and in each other Transaction Document is between the Company, each
Subsidiary and a Purchaser, solely, and not between the Company, its Subsidiaries and the Purchasers collectively and not between
and among the Purchasers.

Section
2.          Interest.


 


(a)       Payment
of Interest in Cash or Kind. The Company shall pay interest to the Holder on the aggregate unconverted and then outstanding
principal amount of this Series A Debenture at the rate of 2.25% per annum, payable quarterly on January 1, April 1, July 1 and
October 1, beginning on the first such date after the Original Issue Date, on each Conversion Date (as to that principal amount
then being converted) 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) all of the Equity Conditions
have been met (unless waived by the Holder in writing) during the 20 Trading Days immediately prior to the applicable Interest
Payment Date (the “Interest Notice Period”) and through and including the date such shares of Common Stock are
actually issued to the Holder, (ii) the Company shall have given the Holder notice in accordance with the notice requirements set
forth below, (iii) the then applicable Conversion Price is less than the Interest Conversion Rate and (iv) as to such Interest
Payment Date, prior to such Interest Notice Period (but not more than five (5) Trading Days prior to the commencement of such Interest
Notice Period), 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”).


 






    	18



    	 



    

 


(b)          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.


 


(c)          Interest
Calculations. 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 shall cease to accrue with respect to any principal amount converted, provided that,
the Company actually delivers the Conversion Shares within the time period required by Section 4(c)(ii) herein. Interest hereunder
will be paid to the Person in whose name this Series A Debenture is registered on the records of the Company regarding registration
and transfers of the Debentures (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; provided, however, that none of foreclosure upon,
any results of foreclosure upon or any proceeds of foreclosure upon any of the Collateral constitute payments made by the Company
for purposes of this sentence.


 


(d)          Late
Fee. All overdue accrued and unpaid interest to be paid hereunder shall entail a late fee at an interest rate equal to the
lesser of 12% 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.

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


 


Section
3.             Registration of Transfers and Exchanges.


 


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


 


(b)          Investment
Representations. This Series A 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 Series A Debenture, the Company and any
agent of the Company may treat the Person in whose name this Series A 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 Series
A Debenture is overdue, and neither the Company nor any such agent shall be affected by notice to the contrary.

Section
4.             Conversion.


 


(a)          Voluntary
Conversion. At any time after the both (i) the Original Issue Date and (ii) the earlier to occur of (1) the Company has received
shareholder approval as required by its Principal Market for the issuance of shares of Common Stock upon conversion of this Series
A Debenture and (2) six months after the Original Issue Date (or until such later date if the Company continues to seek shareholder
approval at the request of the Holders), and until this Series A Debenture is no longer outstanding, this Series A 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 this Section 4(a) and in Section 4(d) hereof). Notwithstanding the foregoing,
if the Company has not obtained Shareholder Approval, the Company may not issue a number of shares of Common Stock, which, when
aggregated with any shares of Common Stock issued (i) pursuant to any Debentures issued pursuant to the Purchase Agreement (whether
upon conversion or as payment of interest), and (ii) upon prior exercise of any Warrant issued pursuant to the Purchase Agreement,
would exceed 1,622,612, subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other
similar transactions of the Common Stock that occur after the date of the Purchase Agreement (such number of shares, the “Issuable
Maximum”). The Holder and the holders of the other Debentures and Warrants issued pursuant to the Purchase Agreement shall
be entitled to a portion of the Issuable Maximum equal to the quotient obtained by dividing (x) the Holder’s original Subscription
Amount by (y) the aggregate original Subscription Amount of all holders pursuant to the Purchase Agreement. In addition, the Holder
may allocate its pro-rata portion of the Issuable Maximum among Warrants and Debentures held by it in its sole discretion. Such
portion shall be adjusted upward ratably in the event a Purchaser (other than the Holder) no longer holds any Warrants or Debentures
and the amount of shares issued to such Purchaser pursuant to its Warrants and Debentures was less than such Purchaser’s
pro-rata share of the Issuable Maximum. 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 Series A Debenture to be converted and the date on which such conversion shall be effected (such date, the “Conversion
Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice
of Conversion is deemed delivered hereunder. No ink-original Notice of Conversion shall be required, nor shall any medallion guarantee
(or other type of guarantee or notarization) of any Notice of Conversion form be required. To effect conversions hereunder, the
Holder shall not be required to physically surrender this Series A Debenture to the Company unless the entire principal amount
of this Series A 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 Series A 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.
In the event of any dispute or discrepancy, the records of the Holder shall be controlling and determinative in the absence of
manifest error. The Holder, and any assignee by acceptance of this Series A Debenture, acknowledge and agree that, by reason
of the provisions of this paragraph, following conversion of a portion of this Series A Debenture, the unpaid and unconverted principal
amount of this Series A 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 $0.75, subject to adjustment herein (the “Conversion
Price”).


 


(c)          Mechanics
of Conversion.


 


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


 






    	21



    	 



    

 


ii          Delivery
of Certificate Upon Conversion. Not later than three (3) Trading Days after each Conversion Date (the “Share Delivery
Date”), the Company shall deliver, or cause to be delivered, to the Holder (A) a certificate or certificates representing
the Conversion Shares which, on or after the earlier of (i) the six month anniversary of the Original Issue Date or (ii) the Effective
Date, shall be free of restrictive legends and trading restrictions (other than those which may then be required by the Purchase
Agreement) representing the number of Conversion Shares being acquired upon the conversion of this Series A 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 earlier of (i) the six month anniversary of the Original Issue Date
or (ii) the Effective Date, the Company shall deliver any certificate or certificates required to be delivered by the Company under
this Section 4(c) electronically through the Depository Trust Company or another established clearing corporation performing similar
functions.


 


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


 






    	22



    	 



    

 


iv          Obligation
Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion
of this Series A 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 Series A 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 Series A Debenture shall have been sought and obtained. 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 third (3rd) Trading Day after such liquidated damages
begin to accrue and increasing to $40 per Trading Day on the sixth Trading Day after such 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.


 






    	23



    	 



    

 


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


  


vi          Reservation
of Shares Issuable Upon Conversion. The Company covenants that it will use its best efforts to promptly seek shareholder approval
for an amendment to its certificate of incorporation to increase the number of authorized shares of Common Stock to permit the
conversion of this Series A Debenture in its entirety and, at all times thereafter, reserve and keep available out of its
authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of this Series A Debenture
and payment of interest on this Series A Debenture, each as herein provided, free from preemptive rights or any other actual
contingent purchase rights of Persons other than the Holder (and the other holders of the Debentures), not less than such aggregate
number of shares of the Common Stock as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable
(taking into account the adjustments and restrictions of Section 5) upon the conversion of the then outstanding principal amount
of this Series A Debenture and payment of interest hereunder. 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 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 such Holder’s compliance with its obligations under the Registration Rights Agreement).


 






    	24



    	 



    

 


vii          Fractional
Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Series A Debenture
or payment of interest on this Series A 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. Each issuance of certificates for shares of Common Stock on conversion of this Series A Debenture or payment
of interest under this Series A Debenture shall be made without charge to the Holder hereof for any documentary stamp or similar
taxes that may be payable in respect of the issue or delivery of such certificates, provided that, the Company shall not be required
to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon
conversion in a name other than that of the Holder of this Series A Debenture so converted and the Company shall not be required
to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to
the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 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 Series A Debenture, and a Holder shall not have
the right to convert any portion of this Series A 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 Series
A 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 Series A 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, preferred stock 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 Series A Debenture is convertible (in relation
to other securities owned by the Holder together with any Affiliates) and of which principal amount of this Series A 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 Series A Debenture may be converted (in relation to other securities owned by
the Holder together with any Affiliates) and which principal amount of this Series A 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 Series A 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 9.99%
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 the Debentures held by the applicable Holder. The 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 Series A Debenture.

Section
5.             Certain Adjustments.


 


(a)          Stock
Dividends and Stock Splits. If the Company, at any time while this Series A Debenture is outstanding: (i) pays a stock dividend
or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock
Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon conversion
of, or payment of interest on, the Debentures), (ii) subdivides outstanding shares of Common Stock into a larger number of shares,
(iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares or
(iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Company, then
the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding
any treasury shares of the Company) outstanding immediately before such event, and of which the denominator shall be the number
of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section shall become effective
immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall
become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b)          Subsequent
Equity Sales. If the Company or any Subsidiary thereof, as applicable, at any time while this Series A Debenture is outstanding,
shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue (or announce
any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents, at an effective
price per share less than the Conversion Price then in effect (such lower price, the “Base Share Price” and
such issuances collectively, a “Dilutive Issuance”) (it being understood and agreed that 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 less 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 at such effective price), then simultaneously with the consummation of each Dilutive Issuance the Conversion
Price shall be reduced to equal the Base Share Price. Such adjustment shall be made whenever such Common Stock or Common Stock
Equivalents are issued. Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section 5(b) in
respect of an Exempt Issuance. The Company shall notify the Holder, in writing, no later than the Trading Day following the issuance
or deemed 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 Share Price regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Conversion.
If the Company enters into a Variable Rate Transaction, despite the prohibition thereon in the Purchase Agreement, the Company
shall be deemed to have issued Common Stock or Common Stock Equivalents at the lowest possible conversion or exercise price at
which such securities may be converted or exercised. Notwithstanding anything herein to the contrary, this Section 5(b) shall terminate
and be of no further force or effect after the later of (i) the one year anniversary of the Original Issue Date, and (ii) the earlier
of (A) six months after the effective date of the registration statement registering all of the shares of Common Stock required
to be registered pursuant to the Registration Rights Agreement (in the event multiple registration statements are required to register
all such shares, then this provision shall refer to the last of such registration statements to become effective), and (B) six
months after the date that all of the Warrant Shares and shares of Common Stock issued or issuable under this Series A Debentures
are freely tradable under Rule 144 without the requirement to be in compliance with the current public information requirements
thereunder.


 






    	27



    	 



    

 


(c)          Subsequent
Rights Offerings. If the Company, at any time while this Series A Debenture is outstanding, shall issue rights, options or
warrants to all holders of Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share
(a “New Issue Price”) that is lower than the Conversion Price on the record date referenced below, then the
Conversion Price shall be reduced to equal such New Issue Price. Such adjustment shall be made whenever such rights, options or
warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled
to receive such rights, options or warrants.


 


(d)          Pro
Rata Distributions. If the Company, at any time while this Series A Debenture is outstanding, shall distribute to all holders
of Common Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights or
warrants to subscribe for or purchase any security, then in each such case the Exercise Price shall be adjusted by multiplying
the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such
distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and of
which the numerator shall be such VWAP on such record date less the then per share fair market value at such record date of the
portion of such assets or evidence of indebtedness or rights or warrants so distributed applicable to one outstanding share of
the Common Stock as determined by the Board of Directors in good faith. In either case the adjustments shall be described in a
statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights
applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become
effective immediately after the record date mentioned above.


 






    	28



    	 



    

 


(e)          Fundamental
Transaction. If, at any time while this Series A 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, (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 Series
A 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 Series A 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 Series A Debenture
is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 4(d) on the conversion
of this Series A Debenture) is convertible. 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 Series A 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 Series A 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 and shall, at the option of the holder of this Series A
Debenture, deliver to the Holder in exchange for this Series A Debenture a security of the Successor Entity evidenced by a written
instrument substantially similar in form and substance to this Series A 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 Series A Debenture (without regard to any limitations on the conversion of this Series A
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 Series A Debenture immediately prior to the consummation of such Fundamental
Transaction). 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 Series A 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 Series A 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)          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 Series A 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 Series A 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.             Mandatory Prepayment. Notwithstanding anything
herein to the contrary, from and after the Original Issue Date until December 31, 2015, at the end of each calendar quarter, the
Company shall determine the aggregate amount of cash received by the Company for (i) the exercise of any warrants, (i) issuance
of any capital stock or other securities exercisable for or exchangeable into shares of capital stock and (iii) capital raised
by any other means (such aggregate amount, the “Capital Raised”). To the extent that the Capital Raised exceeds
$4 million (such excess, the “Excess Capital”), the Company shall, within five (5) Trading Days from the end
of each such calendar quarter, send the Holder a notice indicating the amount of Capital Raised from the Original Issue Date to
date. The Holder hereof shall within five (5) Trading Days, by notice to the Company, elect whether to receive repayment of all
or part of the Excess Capital. The Company shall pay to the Holder (and the Holders of other Debt Securities electing to receive
repayment of the Excess Capital) the portion of the Excess Capital (less any Excess Capital previously repaid) which equals the
amount obtained by multiplying the Excess Capital by a fraction, the numerator of which is the principal amount of this Series A
Debenture and the denominator of which is the principal amount of all Debt Securities which have requested repayment of the Excess
Capital.


 


Section
7.             Negative Covenants. As long as any portion of
this Series A Debenture remains outstanding, unless the holders of at least 67% in principal amount of the then outstanding Debt
Securities shall have otherwise given prior written consent, the Company shall not, and shall not permit any of the Subsidiaries
to, directly or indirectly:


 


(a)          other
than Permitted Indebtedness, enter into, create, incur, assume, guarantee or suffer to exist any indebtedness for borrowed money
of any kind, including, but not limited to, a guarantee, on or with respect to any of its property or assets now owned or hereafter
acquired or any interest therein or any income or profits therefrom;


 


(b)          other
than Permitted Liens, enter into, create, incur, assume or suffer to exist any Liens of any kind, on or with respect to any of
its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom;


 


(c)          amend
its charter documents, including, without limitation, its certificate of incorporation and bylaws, in any manner that materially
and adversely affects any rights of the Holder;


 


(d)          repay,
repurchase or offer to repay, repurchase or otherwise acquire more than a de minimis number of shares of its Common
Stock or Common Stock Equivalents other than as to (i) the Conversion Shares or Warrant Shares as permitted or required under the
Transaction Documents and (ii) repurchases of Common Stock or Common Stock Equivalents of departing officers and directors of the
Company, provided that such repurchases shall not exceed an aggregate of $75,000 per year for all officers and directors during
the term of this Series A Debenture;


 


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


 






    	31

of the Company (even if less than a quorum otherwise required for board approval); or


 


(h)          enter
into any agreement with respect to any of the foregoing.

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 Series A Debenture, the interest rate
on this Series A Debenture shall accrue at an interest rate equal to the lesser of 12% per annum or the maximum rate permitted

the Holder shall have all rights as a holder of this Series A 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 Series A 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,

now or hereafter issued under the terms set forth herein.          


 


(c)          Lost
or Mutilated Debenture. If this Series A Debenture shall be mutilated, lost, stolen or destroyed, the Company shall execute

so mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or destruction of such Series A
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 Series A Debenture shall be
governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles
of conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement and defense
of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its respective
Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts sitting
in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for
such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery)

    	35



    	 



    

 


(e)          Waiver.
Any waiver by the Company or the Holder of a breach of any provision of this Series A 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 Series A Debenture. The failure
of the Company or the Holder to insist upon strict adherence to any term of this Series A 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 Series A Debenture on any other occasion. Any waiver by the Company or the Holder must be in writing.


 


(f)          Severability.
If any provision of this Series A Debenture is invalid, illegal or unenforceable, the balance of this Series A Debenture shall
remain in effect, and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable to
all other Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates
the applicable law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum
rate of interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it shall
not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension
or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest

Section

principal amount of this Series B Debenture at the rate of 2.25% per annum, payable quarterly on January 1, April 1, July 1 and
October 1, beginning on the first such date after the Original Issue Date, on each Conversion Date (as to that principal amount

set forth below, (iii) the then applicable Conversion Price is less than the Interest Conversion Rate and (iv) as to such Interest
Payment Date, prior to such Interest Notice Period (but not more than five (5) Trading Days prior to the commencement of such

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”).


 






    	Exhibit A-2-7



    	 



    

 


(b)          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.


 


(c)          Interest
Calculations. 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 shall cease to accrue with respect to any principal amount converted, provided
that, the Company actually delivers the Conversion Shares within the time period required by Section 4(c)(ii) herein. Interest
hereunder will be paid to the Person in whose name this Series B Debenture is registered on the records of the Company regarding
registration and transfers of the Debentures (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; provided, however,
that none of foreclosure upon, any results of foreclosure upon or any proceeds of foreclosure upon any of the Collateral constitute
payments made by the Company for purposes of this sentence.


 


(d)          Late
Fee. All overdue accrued and unpaid interest to be paid hereunder shall entail a late fee at an interest rate equal to the
lesser of 12% 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.

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


 


Section
3.             Registration
of Transfers and Exchanges.


 


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


 


(b)          Investment
Representations. This Series B 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 Series B Debenture, the Company and any
agent of the Company may treat the Person in whose name this Series B 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 Series
B Debenture is overdue, and neither the Company nor any such agent shall be affected by notice to the contrary.


 


Section
4.             Conversion.


 


(a)          Voluntary
Conversion. At any time after the both (i) the Original Issue Date and (ii) the earlier to occur of (1) the Company has received
shareholder approval as required by its Principal Market for the issuance of shares of Common Stock upon conversion of this Series
B Debenture and (2) six months after the Original Issue Date (or until such later date if the Company continues to seek shareholder
approval at the request of the Holders), and until this Series B Debenture is no longer outstanding, this Series B 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 this Section 4(a) and in Section 4(d) hereof). Notwithstanding the foregoing,
if the Company has not obtained Shareholder Approval, the Company may not issue a number of shares of Common Stock, which, when
aggregated with any shares of Common Stock issued (i) pursuant to any Debentures issued pursuant to the Purchase Agreement (whether
upon conversion or as payment of interest), and (ii) upon prior exercise of any Warrant issued pursuant to the Purchase Agreement,
would exceed 1,622,612, subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other
similar transactions of the Common Stock that occur after the date of the Purchase Agreement (such number of shares, the “Issuable
Maximum”). The Holder and the holders of the other Debentures and Warrants issued pursuant to the Purchase Agreement
shall be entitled to a portion of the Issuable Maximum equal to the quotient obtained by dividing (x) the Holder’s original
Subscription Amount by (y) the aggregate original Subscription Amount of all holders pursuant to the Purchase Agreement. In addition,
the Holder may allocate its pro-rata portion of the Issuable Maximum among Warrants and Debentures held by it in its sole discretion.
Such portion shall be adjusted upward ratably in the event a Purchaser (other than the Holder) no longer holds any Warrants or
Debentures and the amount of shares issued to such Purchaser pursuant to its Warrants and Debentures was less than such Purchaser’s
pro-rata share of the Issuable Maximum. 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 Series B Debenture to be converted and the date on which such conversion shall be effected (such
date, the “Conversion Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion
Date shall be the date that such Notice of Conversion is deemed delivered hereunder. No ink-original Notice of Conversion shall
be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion form be
required. To effect conversions hereunder, the Holder shall not be required to physically surrender this Series B Debenture
to the Company unless the entire principal amount of this Series B 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 Series B 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. In the event of any dispute or discrepancy, the records of the Holder shall
be controlling and determinative in the absence of manifest error. The Holder, and any assignee by acceptance of this Series
B Debenture, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this
Series B Debenture, the unpaid and unconverted principal amount of this Series B 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 $0.75, subject to adjustment herein
(the “Conversion Price”).


 


(c)          Mechanics
of Conversion.


 


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


 


ii         Delivery
of Certificate Upon Conversion. Not later than three (3) Trading Days after each Conversion Date (the “Share Delivery
Date”), the Company shall deliver, or cause to be delivered, to the Holder (A) a certificate or certificates representing
the Conversion Shares which, on or after the earlier of (i) the six month anniversary of the Original Issue Date or (ii) the Effective
Date, shall be free of restrictive legends and trading restrictions (other than those which may then be required by the Purchase
Agreement) representing the number of Conversion Shares being acquired upon the conversion of this Series B 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 earlier of (i) the six month anniversary of the Original Issue Date
or (ii) the Effective Date, the Company shall deliver any certificate or certificates required to be delivered by the Company
under this Section 4(c) electronically through the Depository Trust Company or another established clearing corporation performing
similar functions.


 






    	Exhibit A-2-10



    	 



    




 


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


 


iv        Obligation
Absolute; Partial Liquidated Damages. The Company’s obligations to issue and deliver the Conversion Shares upon conversion
of this Series B 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 Series B 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 Series B Debenture shall have been sought and obtained. 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 third (3rd) Trading Day after such liquidated
damages begin to accrue and increasing to $40 per Trading Day on the sixth Trading Day after such 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.


 






    	Exhibit A-2-11



    	 



    

 


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


 






    	Exhibit A-2-12



    	 



    

 


vi        Reservation
of Shares Issuable Upon Conversion. The Company covenants that it will use its best efforts to promptly seek shareholder approval
for an amendment to its certificate of incorporation to increase the number of authorized shares of Common Stock to permit the
conversion of this Series B Debenture in its entirety and, at all times thereafter, reserve and keep available out of its authorized
and unissued shares of Common Stock for the sole purpose of issuance upon conversion of this Series B Debenture and payment of
interest on this Series B Debenture, each as herein provided, free from preemptive rights or any other actual contingent purchase
rights of Persons other than the Holder (and the other holders of the Debentures), not less than such aggregate number of shares
of the Common Stock as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into
account the adjustments and restrictions of Section 5) upon the conversion of the then outstanding principal amount of this Series
B Debenture and payment of interest hereunder. 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 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 such Holder’s compliance with its obligations under the Registration Rights Agreement).


 






    	Exhibit A-2-13



    	 



    

 


vii       Fractional
Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of this Series B
Debenture or payment of interest on this Series B 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. Each issuance of certificates for shares of Common Stock on conversion of this Series B Debenture or payment
of interest under this Series B Debenture shall be made without charge to the Holder hereof for any documentary stamp or similar
taxes that may be payable in respect of the issue or delivery of such certificates, provided that, the Company shall not be required
to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon
conversion in a name other than that of the Holder of this Series B Debenture so converted and the Company shall not be required
to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to
the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid. 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 Series B Debenture, and a Holder shall not have
the right to convert any portion of this Series B 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 Series
B 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 Series B 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, preferred stock 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 Series B Debenture
is convertible (in relation to other securities owned by the Holder together with any Affiliates) and of which principal amount
of this Series B 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 Series B Debenture may be converted (in relation to other
securities owned by the Holder together with any Affiliates) and which principal amount of this Series B 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 Series B 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 the Debentures held by the applicable Holder. The 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 Series B Debenture.

Section
5.             Certain
Adjustments.


 


(a)          Stock
Dividends and Stock Splits. If the Company, at any time while this Series B Debenture is outstanding: (i) pays a stock dividend
or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any Common Stock
Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon conversion
of, or payment of interest on, the Debentures), (ii) subdivides outstanding shares of Common Stock into a larger number of shares,
(iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares
or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the Company,
then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock
(excluding any treasury shares of the Company) outstanding immediately before such event, and of which the denominator shall be
the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section shall
become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or
distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.


 






    	Exhibit A-2-15



    	 



    

 


(b)          Subsequent
Equity Sales. If the Company or any Subsidiary thereof, as applicable, at any time while this Series B Debenture is outstanding,
shall sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue (or announce
any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents, at an effective
price per share less than the Conversion Price then in effect (such lower price, the “Base Share Price” and
such issuances collectively, a “Dilutive Issuance”) (it being understood and agreed that 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 less 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 at such effective price), then simultaneously with the consummation of each Dilutive Issuance the Conversion
Price shall be reduced to equal the Base Share Price. Such adjustment shall be made whenever such Common Stock or Common Stock
Equivalents are issued. Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section 5(b) in
respect of an Exempt Issuance. The Company shall notify the Holder, in writing, no later than the Trading Day following the issuance
or deemed 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 Share Price regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Conversion.
If the Company enters into a Variable Rate Transaction, despite the prohibition thereon in the Purchase Agreement, the Company
shall be deemed to have issued Common Stock or Common Stock Equivalents at the lowest possible conversion or exercise price at
which such securities may be converted or exercised. Notwithstanding anything herein to the contrary, this Section 5(b) shall
terminate and be of no further force or effect after the later of (i) the one year anniversary of the Original Issue Date, and
(ii) the earlier of (A) six months after the effective date of the registration statement registering all of the shares of Common
Stock required to be registered pursuant to the Registration Rights Agreement (in the event multiple registration statements are
required to register all such shares, then this provision shall refer to the last of such registration statements to become effective),
and (B) six months after the date that all of the Warrant Shares and shares of Common Stock issued or issuable under this Series
B Debentures are freely tradable under Rule 144 without the requirement to be in compliance with the current public information
requirements thereunder.


 


(c)          Subsequent
Rights Offerings. If the Company, at any time while this Series B Debenture is outstanding, shall issue rights, options or
warrants to all holders of Common Stock entitling them to subscribe for or purchase shares of Common Stock at a price per share
(a “New Issue Price”) that is lower than the Conversion Price on the record date referenced below, then the
Conversion Price shall be reduced to equal such New Issue Price. Such adjustment shall be made whenever such rights, options or
warrants are issued, and shall become effective immediately after the record date for the determination of stockholders entitled
to receive such rights, options or warrants.


 






    	Exhibit A-2-16



    	 



    

 


(d)          Pro
Rata Distributions. If the Company, at any time while this Series B Debenture is outstanding, shall distribute to all holders
of Common Stock (and not to the Holder) evidences of its indebtedness or assets (including cash and cash dividends) or rights
or warrants to subscribe for or purchase any security, then in each such case the Exercise Price shall be adjusted by multiplying
the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive
such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date mentioned above, and
of which the numerator shall be such VWAP on such record date less the then per share fair market value at such record date of
the portion of such assets or evidence of indebtedness or rights or warrants so distributed applicable to one outstanding share
of the Common Stock as determined by the Board of Directors in good faith. In either case the adjustments shall be described in
a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription rights
applicable to one share of Common Stock. Such adjustment shall be made whenever any such distribution is made and shall become
effective immediately after the record date mentioned above.


 


(e)          Fundamental
Transaction. If, at any time while this Series B 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, (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 Series B 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 Series B 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 Series
B Debenture is convertible immediately prior to such Fundamental Transaction (without regard to any limitation in Section 4(d)
on the conversion of this Series B Debenture) is convertible. 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 Series B 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 Series B 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 and shall, at the
option of the holder of this Series B Debenture, deliver to the Holder in exchange for this Series B Debenture a security of the
Successor Entity evidenced by a written instrument substantially similar in form and substance to this Series B 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 Series B Debenture (without regard to any limitations
on the conversion of this Series B 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 Series B Debenture immediately
prior to the consummation of such Fundamental Transaction). 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 Series B 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 Series B 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)          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.


 






    	Exhibit A-2-18



    	 



    

 


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 Series B 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 Series B 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.             Mandatory
Prepayment. Notwithstanding anything herein to the contrary, from and after the Original Issue Date until December 31, 2015,
at the end of each calendar quarter, the Company shall determine the aggregate amount of cash received by the Company for (i)
the exercise of any warrants, (i) issuance of any capital stock or other securities exercisable for or exchangeable into shares
of capital stock and (iii) capital raised by any other means (such aggregate amount, the “Capital Raised”).
To the extent that the Capital Raised exceeds $4 million (such excess, the “Excess Capital”), the Company shall,
within five (5) Trading Days from the end of each such calendar quarter, send the Holder a notice indicating the amount of Capital
Raised from the Original Issue Date to date. The Holder hereof shall within five (5) Trading Days, by notice to the Company, elect
whether to receive repayment of all or part of the Excess Capital. The Company shall pay to the Holder (and the Holders of other
Debt Securities electing to receive repayment of the Excess Capital) the portion of the Excess Capital (less any Excess Capital
previously repaid) which equals the amount obtained by multiplying the Excess Capital by a fraction, the numerator of which is
the principal amount of this Series B Debenture and the denominator of which is the principal amount of all Debt Securities which
have requested repayment of the Excess Capital.


 


Section
7.             Negative
Covenants. As long as any portion of this Series B Debenture remains outstanding, unless the holders of at least 67% in principal
amount of the then outstanding Debt Securities shall have otherwise given prior written consent, the Company shall not, and shall
not permit any of the Subsidiaries to, directly or indirectly:


 


(a)          other

acquired or any interest therein or any income or profits therefrom;


 


(b)          other
than Permitted Liens, enter into, create, incur, assume or suffer to exist any Liens of any kind, on or with respect to any of
its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom;


 


(c)          amend
its charter documents, including, without limitation, its certificate of incorporation and bylaws, in any manner that materially
and adversely affects any rights of the Holder;


 


(d)          repay,
repurchase or offer to repay, repurchase or otherwise acquire more than a de minimis number of shares of its Common

the Transaction Documents and (ii) repurchases of Common Stock or Common Stock Equivalents of departing officers and directors
of the Company, provided that such repurchases shall not exceed an aggregate of $75,000 per year for all officers and directors
during the term of this Series B Debenture;


 


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

(f)          pay

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 this Series B 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.

U.S. nationally recognized overnight courier service or (iv) upon actual receipt by the party to whom such notice is required
to be given.


 


(b)          Absolute
Obligation. Except as expressly provided herein, no provision of this Series B 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 Series B Debenture at the time, place, and rate, and in the coin or currency, herein prescribed. This Series B Debenture
is a direct debt obligation of the Company. This Series B Debenture ranks pari passu with all other Debt Securities
now or hereafter issued under the terms set forth herein.


 


(c)          Lost
or Mutilated Debenture. If this Series B 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 Series B Debenture, or in lieu of or in substitution

so mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or destruction of such Series B
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 Series B Debenture shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflict of laws thereof. Each party agrees that all legal proceedings concerning the interpretation, enforcement
and defense of the transactions contemplated by any of the Transaction Documents (whether brought against a party hereto or its
respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced in the state and federal courts
sitting in the City of New York, Borough of Manhattan (the “New York Courts”). Each party hereto hereby irrevocably
submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith
or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction
Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of such New York Courts, or such New York Courts are improper or inconvenient venue for
such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence
of delivery) to such party at the address in effect for notices to it under this Series B Debenture and agrees that such service
shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit
in any way any right to serve process in any other manner permitted by applicable law. Each party hereto hereby irrevocably waives,
to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or
relating to this Series B Debenture or the transactions contemplated hereby. If any party shall commence an action or proceeding
to enforce any provisions of this Series B Debenture, then the prevailing party in such action or proceeding shall be reimbursed
by the other party for its attorneys’ fees and other costs and expenses incurred in the investigation, preparation and prosecution
of such action or proceeding.


 






    	Exhibit A-2-24



    	 



    

 


(e)          Waiver.
Any waiver by the Company or the Holder of a breach of any provision of this Series B 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 Series B Debenture. The failure
of the Company or the Holder to insist upon strict adherence to any term of this Series B 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 Series B Debenture on any other occasion. Any waiver by the Company or the Holder must be in writing.


 


(f)          Severability.
If any provision of this Series B Debenture is invalid, illegal or unenforceable, the balance of this Series B Debenture shall
remain in effect, and if any provision is inapplicable to any Person or circumstance, it shall nevertheless remain applicable
to all other Persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder violates
the applicable law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the
maximum rate of interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that
it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay,
extension or usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal
of or interest on this Series B 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 Series B 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.


 






    	Exhibit A-2-25



    	 



    

 


(g)          Remedies,
Characterizations, Other Obligations, Breaches and Injunctive Relief.  The remedies provided in this Series B Debenture
shall be cumulative and in addition to all other remedies available under this Series B 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 Series B 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 Series B Debenture.


 


(h)          Next
Business Day. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment
shall be made on the next succeeding Business Day.


 


(i)          Headings.
The headings contained herein are for convenience only, do not constitute a part of this Series B 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 Series B Debenture are secured by all assets of the Company pursuant
to the Security Documents.

FORM
OF SUBSIDIARY GUARANTEE


 


SUBSIDIARY
GUARANTEE, dated as of __________ __, 20__ (this “Guarantee”), made by each of the signatories hereto (together
with any other entity that may become a party hereto as provided herein, the “Guarantors”), in favor of the
purchasers (the “Purchasers”) signatory to that certain Securities Purchase Agreement dated as of June 22,
2015 (as amended, the “Purchase Agreement”) made by and among MELA Sciences, Inc., a Delaware corporation (the
“Company”) and the Purchasers.


 


W
I T N E S S E T H:


 


WHEREAS,
pursuant to the Purchase Agreement the Company has issued and sold to the Purchasers the Company’s 2.25% Series A Senior
Secured Convertible Debentures due June 22, 2020 (the “Series A Debentures”), the Company’s
2.25% Series B Senior Unsecured Convertible Debentures due June 22, 2020 (the “Series B Debentures”
and, together with the Series A Debentures, the “Debentures”) and the Company’s 9% Senior Secured
Notes (the “Notes” and, together with the Debentures, the “Debt Securities”); and


 


WHEREAS,
each Guarantor directly benefits from the extension of credit to the Company represented by the Debt Securities.


 


NOW,
THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and adequacy of which
are hereby acknowledged, each of the Guarantors hereby agrees with the Purchasers as follows:


 


1             Definitions.
Unless otherwise defined herein, terms defined in the Purchase Agreement and used herein shall have the respective meanings given
to them in the Purchase Agreement. The words “hereof,” “herein,” “hereto” and “hereunder”
and words of similar import when used in this Guarantee shall refer to this Guarantee as a whole and not to any particular provision
of this Guarantee, and Section and Schedule references are to this Guarantee unless otherwise specified. The meanings given to
terms defined herein shall be equally applicable to both the singular and plural forms of such terms. The following terms shall
have the following meanings:


 


 “Guarantee”
means this Subsidiary Guarantee, as the same may be amended, supplemented or otherwise modified from time to time.


 


“Obligations”
means, in addition to all other costs and expenses of collection incurred by the Purchasers in enforcing any of such Obligations
and/or this Guarantee, all of the liabilities and obligations (primary, secondary, direct, contingent, sole, joint or several)
due or to become due, or that are now or may be hereafter contracted or acquired, or owing to, of the Company or any Guarantor
to the Purchasers, including, without limitation, all obligations under this Guarantee, the Debentures, the Debt Securities and
any other instruments, agreements or other documents executed and/or delivered in connection herewith or therewith, in each case,
whether now or hereafter existing, voluntary or involuntary, direct or indirect, absolute or contingent, liquidated or unliquidated,
whether or not jointly owed with others, and whether or not from time to time decreased or extinguished and later increased, created
or incurred, and all or any portion of such obligations or liabilities that are paid, to the extent all or any part of such payment
is avoided or recovered directly or indirectly from any of the Purchasers as a preference, fraudulent transfer or otherwise as
such obligations may be amended, supplemented, converted, extended or modified from time to time. Without limiting the generality
of the foregoing, the term “Obligations” shall include, without limitation: (i) principal of, and interest on the
Debt Securities and the loans extended pursuant thereto; (ii) any and all other fees, indemnities, costs, obligations and liabilities
of the Company or any Guarantor from time to time under or in connection with this Guarantee, the Debt Securities and any other
instruments, agreements or other documents executed and/or delivered in connection herewith or therewith; and (iii) all amounts
(including but not limited to post-petition interest) in respect of the foregoing that would be payable but for the fact that
the obligations to pay such amounts are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or
similar proceeding involving the Company or any Guarantor.


 






    	 



    	 



    

 


2              Guarantee.


 


(a)          Guarantee.


 


i            The
Guarantors hereby, jointly and severally, unconditionally and irrevocably, guarantee to the Purchasers, and each of their respective
successors, indorsees, transferees and assigns, the prompt and complete payment and performance when due (whether at the stated
maturity, by acceleration or otherwise) of the Obligations.


 


ii           Anything
herein or in any other Transaction Document to the contrary notwithstanding, the maximum liability of each Guarantor hereunder
and under the other Transaction Documents shall in no event exceed the amount which can be guaranteed by such Guarantor under
applicable federal and state laws, including laws relating to the insolvency of debtors, fraudulent conveyance or transfer or
laws affecting the rights of creditors generally (after giving effect to the right of contribution established in Section 2(b)).


 


iii          Each
Guarantor agrees that the Obligations may at any time and from time to time exceed the amount of the liability of such Guarantor
hereunder without impairing the guarantee contained in this Section 2 or affecting the rights and remedies of the Purchasers hereunder.


 


iv         The
guarantee contained in this Section 2 shall remain in full force and effect until all the Obligations and the obligations of each
Guarantor under the guarantee contained in this Section 2 shall have been satisfied by indefeasible payment in full.


 


v          No
payment made by the Company, any of the Guarantors, any other guarantor or any other Person or received or collected by the Purchasers
from the Company, any of the Guarantors, any other guarantor or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application at any time or from time to time in reduction of or in payment of the Obligations shall
be deemed to modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall, notwithstanding
any such payment (other than any payment made by such Guarantor in respect of the Obligations or any payment received or collected
from such Guarantor in respect of the Obligations), remain liable for the Obligations up to the maximum liability of such Guarantor
hereunder until the Obligations are indefeasibly paid in full.

vi          Notwithstanding
anything to the contrary in this Guarantee, with respect to any defaulted non-monetary Obligations the specific performance of
which by the Guarantors is not reasonably possible (e.g. the issuance of the Company’s Common Stock), the Guarantors shall
only be liable for making the Purchasers whole on a monetary basis for the Company’s failure to perform such Obligations
in accordance with the Transaction Documents.


 


(b)          Right
of Contribution. Subject to Section 2(c), each Guarantor hereby agrees that to the extent that a Guarantor shall have paid
more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive contribution
from and against any other Guarantor hereunder which has not paid its proportionate share of such payment. Each Guarantor’s
right of contribution shall be subject to the terms and conditions of Section 2(c). The provisions of this Section 2(b) shall
in no respect limit the obligations and liabilities of any Guarantor to the Purchasers and each Guarantor shall remain liable
to the Purchasers for the full amount guaranteed by such Guarantor hereunder.


 


(c)          No
Subrogation. Notwithstanding any payment made by any Guarantor hereunder or any set-off or application of funds of any Guarantor
by the Purchasers, no Guarantor shall be entitled to be subrogated to any of the rights of the Purchasers against the Company
or any other Guarantor or any collateral security or guarantee or right of offset held by the Purchasers for the payment of the
Obligations, nor shall any Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other
Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Purchasers by the Company on
account of the Obligations are paid in full. If any amount shall be paid to any Guarantor on account of such subrogation rights
at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust
for the Purchasers, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned
over to the Purchasers in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Purchasers, if required),
to be applied against the Obligations, whether matured or unmatured, in such order as the Purchasers may determine.


 


(d)          Amendments,
Etc. With Respect to the Obligations. Each Guarantor shall remain obligated hereunder notwithstanding that, without any reservation
of rights against any Guarantor and without notice to or further assent by any Guarantor, any demand for payment of any of the
Obligations made by the Purchasers may be rescinded by such Purchaser, as applicable, and any of the Obligations continued, and
the Obligations, or the liability of any other Person upon or for any part thereof, or any collateral security or guarantee therefor
or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by the Purchasers in accordance with the Purchase Agreement, and the
Purchase Agreement and the other Transaction Documents and any other documents executed and delivered in connection therewith
may be amended, modified, supplemented or terminated, in whole or in part, as the Purchasers may deem advisable from time to time
in accordance with the Purchase Agreement, and any collateral security, guarantee or right of offset at any time held by the Purchasers
for the payment of the Obligations may be sold, exchanged, waived, surrendered or released. None of the Purchasers shall have
any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for the
guarantee contained in this Section 2 or any property subject thereto.


 






    	3



    	 



    

 


(e)          Guarantee
Absolute and Unconditional. Each Guarantor waives any and all notice of the creation, renewal, extension or accrual of any
of the Obligations and notice of or proof of reliance by the Purchasers upon the guarantee contained in this Section 2 or acceptance
of the guarantee contained in this Section 2; the Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred, or renewed, extended, amended or waived, in reliance upon the guarantee contained in this Section 2; and
all dealings between the Company and any of the Guarantors, on the one hand, and the Purchasers, on the other hand, likewise shall
be conclusively presumed to have been had or consummated in reliance upon the guarantee contained in this Section 2. Each Guarantor
waives to the extent permitted by law diligence, presentment, protest, demand for payment and notice of default or nonpayment
to or upon the Company or any of the Guarantors with respect to the Obligations. Each Guarantor understands and agrees that the
guarantee contained in this Section 2 shall be construed as a continuing, absolute and unconditional guarantee of payment and
performance without regard to (a) the validity or enforceability of the Purchase Agreement or any other Transaction Document,
any of the Obligations or any other collateral security therefor or guarantee or right of offset with respect thereto at any time
or from time to time held by the Purchasers, (b) any defense, set-off or counterclaim (other than a defense of payment or performance
or fraud by the Purchasers) which may at any time be available to or be asserted by the Company or any other Person against the
Purchasers, or (c) any other circumstance whatsoever (with or without notice to or knowledge of the Company or such Guarantor)
which constitutes, or might be construed to constitute, an equitable or legal discharge of the Company for the Obligations, or
of such Guarantor under the guarantee contained in this Section 2, in bankruptcy or in any other instance. When making any demand
hereunder or otherwise pursuing its rights and remedies hereunder against any Guarantor, the Purchasers may, but shall be under
no obligation to, make a similar demand on or otherwise pursue such rights and remedies as they may have against the Company,
any other Guarantor or any other Person or against any collateral security or guarantee for the Obligations or any right of offset
with respect thereto, and any failure by the Purchasers to make any such demand, to pursue such other rights or remedies or to
collect any payments from the Company, any other Guarantor or any other Person or to realize upon any such collateral security
or guarantee or to exercise any such right of offset, or any release of the Company, any other Guarantor or any other Person or
any such collateral security, guarantee or right of offset, shall not relieve any Guarantor of any obligation or liability hereunder,
and shall not impair or affect the rights and remedies, whether express, implied or available as a matter of law, of the Purchasers
against any Guarantor. For the purposes hereof, “demand” shall include the commencement and continuance of any legal
proceedings.


 






    	4



    	 



    

 


(f)          Reinstatement.
The guarantee contained in this Section 2 shall continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored or returned by the Purchasers
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any Guarantor, or upon or as a result
of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Company or any Guarantor
or any substantial part of its property, or otherwise, all as though such payments had not been made.


 


(g)          Payments.
Each Guarantor hereby guarantees that payments hereunder will be paid to the Purchasers, without set-off or counterclaim in U.S.
dollars at the address set forth or referred to in the signature pages to the Purchase Agreement.


 


3              Representations
and Warranties. Each Guarantor hereby makes the following representations and warranties to the Purchasers as of the date
hereof:


 


(a)          Organization
and Qualification. The Guarantor is a corporation, duly incorporated, validly existing and in good standing under the laws
of the applicable jurisdiction set forth on Schedule 1, with the requisite corporate power and authority to own and use
its properties and assets and to carry on its business as currently conducted. The Guarantor has no subsidiaries other than those
identified as such on the Disclosure Schedules to the Purchase Agreement. The Guarantor is duly qualified to do business and is
in good standing as a foreign corporation in each jurisdiction in which the nature of the business conducted or property owned
by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be,
could not, individually or in the aggregate, (x) adversely affect the legality, validity or enforceability of any of this Guaranty
in any material respect, (y) have a material adverse effect on the results of operations, assets, or financial condition of the
Guarantor or (z) adversely impair in any material respect the Guarantor’s ability to perform fully on a timely basis its
obligations under this Guaranty (a “Material Adverse Effect”).


 


(b)          Authorization;
Enforcement. The Guarantor has the requisite corporate power and authority to enter into and to consummate the transactions
contemplated by this Guaranty, and otherwise to carry out its obligations hereunder. The execution and delivery of this Guaranty
by the Guarantor and the consummation by it of the transactions contemplated hereby have been duly authorized by all requisite
corporate action on the part of the Guarantor. This Guaranty has been duly executed and delivered by the Guarantor and constitutes
the valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating
to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general
application.


 


(c)          No
Conflicts. The execution, delivery and performance of this Guaranty by the Guarantor and the consummation by the Guarantor
of the transactions contemplated thereby do not and will not (i) conflict with or violate any provision of its Certificate of
Incorporation or By-laws or (ii) conflict with, constitute a default (or an event which with notice or lapse of time or both would
become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement,
indenture or instrument to which the Guarantor is a party, or (iii) result in a violation of any law, rule, regulation, order,
judgment, injunction, decree or other restriction of any court or governmental authority to which the Guarantor is subject (including
Federal and State securities laws and regulations), or by which any material property or asset of the Guarantor is bound or affected,
except in the case of each of clauses (ii) and (iii), such conflicts, defaults, terminations, amendments, accelerations, cancellations
and violations as could not, individually or in the aggregate, have or result in a Material Adverse Effect. The business of the
Guarantor is not being conducted in violation of any law, ordinance or regulation of any governmental authority, except for violations
which, individually or in the aggregate, do not have a Material Adverse Effect.


 






    	5



    	 



    

 


(d)          Consents
and Approvals. The Guarantor is not required to obtain any consent, waiver, authorization or order of, or make any filing
or registration with, any court or other federal, state, local, foreign or other governmental authority or other person in connection
with the execution, delivery and performance by the Guarantor of this Guaranty.


 


(e)          Purchase
Agreement. The representations and warranties of the Company set forth in the Purchase Agreement as they relate to such Guarantor,
each of which is hereby incorporated herein by reference, are true and correct as of each time such representations are deemed
to be made pursuant to such Purchase Agreement, and the Purchasers shall be entitled to rely on each of them as if they were fully
set forth herein, provided that each reference in each such representation and warranty to the Company’s knowledge shall,
for the purposes of this Section 3, be deemed to be a reference to such Guarantor’s knowledge.


 


4              Covenants.


 


(a)          Each
Guarantor covenants and agrees with the Purchasers that, from and after the date of this Guarantee until the Obligations shall
have been indefeasibly paid in full, such Guarantor shall take, and/or shall refrain from taking, as the case may be, each commercially
reasonable action that is necessary to be taken or not taken, as the case may be, so that no Event of Default (as defined in the
Debentures) is caused by the failure to take such action or to refrain from taking such action by such Guarantor.


 


(b)          So
long as any of the Obligations are outstanding, unless Purchasers holding at least 67% of the aggregate principal amount of the
then outstanding Debt Securities (the “Requisite Purchasers”) shall otherwise consent in writing or except
as otherwise expressly permitted by the Transaction Documents, each Guarantor will not directly or indirectly on or after the
date of this Guarantee:


 


i           enter
into, create, incur, assume or suffer to exist any indebtedness for borrowed money of any kind, including but not limited to,
a guarantee, on or with respect to any of its property or assets now owned or hereafter acquired or any interest therein or any
income or profits therefrom;


 


ii          enter
into, create, incur, assume or suffer to exist any liens of any kind, on or with respect to any of its property or assets now
owned or hereafter acquired or any interest therein or any income or profits therefrom;


 






    	6



    	 



    

 


iii          amend
its certificate of incorporation, bylaws or other charter documents so as to adversely affect any rights of any Purchaser;


 


iv          repay,
repurchase or offer to repay, repurchase or otherwise acquire more than a de minimis number of shares of its securities
or debt obligations;


 


v          pay
cash dividends on any equity securities of the Company;


 


vi         enter
into any transaction with any Affiliate of the Guarantor which would be required to be disclosed in any public filing of the Company
with the Commission, unless such transaction is made on an arm’s-length basis and expressly approved by a majority of the
disinterested directors of the Company (even if less than a quorum otherwise required for board approval); or


 


vii        enter
into any agreement with respect to any of the foregoing.


 


5              Miscellaneous.


 


(a)          Amendments
in Writing. None of the terms or provisions of this Guarantee may be waived, amended, supplemented or otherwise modified except
in writing by Requisite Purchasers provided, however, that unanimous consent of the Purchasers shall be required
for any amendment that would adversely affect any Purchaser.


 


(b)          Notices.
All notices, requests and demands to or upon the Purchasers or any Guarantor hereunder shall be effected in the manner provided
for in the Purchase Agreement, provided that any such notice, request or demand to or upon any Guarantor shall be addressed to
such Guarantor at its notice address set forth on Schedule 5(b).


 


(c)          No
Waiver By Course Of Conduct; Cumulative Remedies. None of the Purchasers shall by any act (except by a written instrument
pursuant to Section 5(a)), delay, indulgence, omission or otherwise be deemed to have waived any right or remedy hereunder or
to have acquiesced in any default under the Transaction Documents or Event of Default. No failure to exercise, nor any delay in
exercising, on the part of the Purchasers, any right, power or privilege hereunder shall operate as a waiver thereof. No single
or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. A waiver by the Purchasers of any right or remedy hereunder on any one occasion shall
not be construed as a bar to any right or remedy which the Purchasers would otherwise have on any future occasion. The rights
and remedies herein provided are cumulative, may be exercised singly or concurrently and are not exclusive of any other rights
or remedies provided by law.


 


(d)          Enforcement
Expenses; Indemnification.


 


i          Each
Guarantor agrees to pay, or reimburse each of the Purchasers for, all its reasonable and documented costs and expenses incurred
in collecting against such Guarantor under the guarantee contained in Section 2 or otherwise enforcing or preserving any
rights under this Guarantee and the other Transaction Documents to which such Guarantor is a party, including, without limitation,
the reasonable fees and disbursements of counsel to each of the Purchasers.


 






    	7



    	 



    

 


ii           Each
Guarantor agrees to pay, and to save each of the Purchasers harmless from, any and all liabilities with respect to, or resulting
from any delay in paying, any and all stamp, excise, sales or other taxes which may be payable or determined to be payable in
connection with any of the transactions contemplated by this Guarantee.


 


iii          Each
Guarantor agrees to pay, and to save each of the Purchasers harmless from, any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution,
delivery, enforcement, performance and administration of this Guarantee to the extent the Company would be required to do so pursuant
to the Purchase Agreement and subject to the limitations contained therein.


 


iv          The
agreements in this Section shall survive repayment of the Obligations and all other amounts payable under the Purchase Agreement
and the other Transaction Documents.


 


(e)          Successor
and Assigns. This Guarantee shall be binding upon the successors and assigns of each Guarantor and shall inure to the benefit
of the Purchasers and their respective successors and assigns; provided that no Guarantor may assign, transfer or delegate any
of its rights or obligations under this Guarantee without the prior written consent of the Requisite Purchasers.


 


(f)          Set-Off.
Each Guarantor hereby irrevocably authorizes the Purchasers at any time and from time to time while an Event of Default under
any of the Transaction Documents shall have occurred and be continuing, without notice to such Guarantor or any other Guarantor,
any such notice being expressly waived by each Guarantor, to set-off and appropriate and apply any and all deposits, credits,
indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured,
at any time held or owing by such Purchaser to or for the credit or the account of such Guarantor, or any part thereof in such
amounts as such Purchaser may elect, against and on account of the obligations and liabilities of such Guarantor to the Purchasers
hereunder and claims of every nature and description of the Purchasers against such Guarantor, in any currency, whether arising
hereunder, under the Purchase Agreement, any other Transaction Document or otherwise, as such Purchaser may elect, whether or
not such Purchaser or any of the other Purchasers has made any demand for payment and although such obligations, liabilities and
claims may be contingent or unmatured. The applicable Purchaser shall notify such Guarantor promptly of any such set-off and the
application made by such Purchaser of the proceeds thereof, provided that the failure to give such notice shall not affect the
validity of such set-off and application. The rights of the Purchasers under this Section are in addition to other rights and
remedies (including, without limitation, other rights of set-off) which the Purchasers may have.


 






    	8



    	 



    

 


(g)          Counterparts.
This Guarantee may be executed by one or more of the parties to this Guarantee on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument.


 


(h)          Severability.
Any provision of this Guarantee which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition
or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.


 


(i)          Section
Headings. The Section headings used in this Guarantee are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by any of the
Purchasers relative to subject matter hereof and thereof not expressly set forth or referred to herein or in the other Transaction
Documents.

Laws. All questions concerning the construction, validity, enforcement and interpretation of this Guarantee 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 conflicts of law thereof. Each of the Company and the Guarantors agree that all proceedings concerning the interpretations,
enforcement and defense of the transactions contemplated by this Guarantee (whether brought against a party hereto or its respective
affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state
and federal courts sitting in the City of New York, Borough of Manhattan. Each of the Company and the Guarantors hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for
the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein,
and hereby irrevocably waives, and agrees not to assert in any proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such proceeding is improper. Each party hereto hereby irrevocably waives personal service
of process and consents to process being served in any such proceeding by mailing a copy thereof via registered or certified mail
or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Guarantee
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any manner permitted by 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 Guarantee or the transactions contemplated hereby.

law, rule or regulation applicable to any Debtor or (ii) conflict with, or constitute a default (or an event that with notice
or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or
cancellation (with or without notice, lapse of time or both) of, any material agreement, or credit facility, to which any Debtor
is a party or by which any property or asset of any Debtor is bound or affected. If any, all required consents (including, without

for Permitted Liens, each Debtor shall at all times maintain the liens and Security Interests provided for hereunder as valid
and perfected first priority liens and security interests in the Collateral located in the United States in favor of the Secured

wherever filing is, or is deemed by the Secured Parties to be, necessary to effect the rights and obligations provided for herein.
Without limiting the generality of the foregoing, each Debtor shall pay all fees, taxes and other amounts necessary to maintain
the Collateral and the Security Interests hereunder, and each Debtor shall obtain and furnish to the Agent from time to time,
upon reasonable request, such releases and/or subordinations of claims and liens which may be required to maintain the priority

the full replacement cost thereof. Each Debtor shall cause each insurance policy issued in connection herewith to provide, and
the insurer issuing such policy to certify to the Secured Parties, that (a) the Secured Parties will be named as lender loss payees
and additional insureds under each such insurance policy; (b) if such insurance be proposed to be cancelled or materially changed

unless the effect of such change is to extend or increase coverage under the policy; and (c) the Secured Parties will have the
right (but no obligation) at its election to remedy any default in the payment of premiums within thirty (30) days of notice from
the insurer of such default. If no Event of Default exists and if the aggregate insurance policy proceeds arising out of any claim
or series of related claims do not exceed $100,000, loss payments in each instance will be applied by the Debtors to the repair
and/or replacement of property with respect to which the loss was incurred to the extent reasonably feasible, and any loss payments
or the balance thereof remaining, to the extent not so applied, shall be payable to the Debtors; provided, however,
that payments received by the Debtors after an Event of Default occurs and is continuing or in excess of $100,000 for any occurrence

possible, then to cause such tangible chattel paper to contain a legend noting that it is subject to the security interest created
by this Agreement. To the extent that any Collateral consists of electronic chattel paper, the applicable Debtor shall cause the
underlying chattel paper to be “marked” within the meaning of Section 9-105 of the UCC (or successor section thereto).


 


(dd)          If
there is any investment property or deposit account included as Collateral that (i) can be perfected by “control”
through an account control agreement, and (ii) at any time has a balance (in either cash or value of investment property, or both)
exceeding $25,000, the applicable Debtor shall cause such an account control agreement, in form and substance in each case satisfactory
to the Secured Parties, to be entered into and delivered to the Secured Parties, unless the Major Investors waive the foregoing
requirement with respect to any such investment property or deposit account otherwise constituting Collateral; provided, that
(x) as of the date of this Agreement, Debtor is not required to provide an account control agreement over the account maintained
by Debtor with J.P. Morgan in Germany as of the date of this Agreement (the “Germany Account”), (y) Debtor
shall notify the Agent at any time that the Germany Account has a balance (in either cash or value of investment property, or
both) exceeding $1,000,000 (a “Germany Account Notice”), and (z) Debtor shall cause an account control agreement,
in form and substance satisfactory to the Secured Parties, to be entered into and delivered to the Secured Parties in respect
of the Germany Account upon instructions from the Secured Parties to do so given by the Secured Parties to Debtor at any time
after Debtor is obligated to deliver a Germany Account Notice pursuant to the preceding clause (y).

(ee)          To
the extent that any Collateral consists of letter-of-credit rights, the applicable Debtor shall cause the issuer of each underlying
letter of credit to consent to an assignment of the proceeds thereof to the Secured Parties.


 


(ff)          To
the extent that any Collateral is in the possession of any third party, the applicable Debtor shall join with the Agent in notifying
such third party of the Secured Parties’ security interest in such Collateral and shall use commercially reasonable efforts
to obtain an acknowledgement and agreement from such third party with respect to the Collateral, in form and substance reasonably
satisfactory to the Agent.


 


(gg)          If
any Debtor shall at any time hold or acquire a commercial tort claim, such Debtor shall promptly notify the Secured Parties in
a writing signed by such Debtor of the particulars thereof and grant to the Secured Parties in such writing a security interest
therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance satisfactory
to the Agent.


 


(hh)           Each
Debtor shall immediately provide written notice to the Agent of any and all accounts which arise out of contracts with any governmental
authority and, to the extent necessary to perfect or continue the perfected status of the Security Interests in such accounts
and proceeds thereof, shall execute and deliver to the Agent an assignment of claims for such accounts and cooperate with the
Agent in taking any other steps required, in its judgment, under the Federal Assignment of Claims Act or any similar federal,
state or local statute or rule to perfect or continue the perfected status of the Security Interests in such accounts and proceeds
thereof.


 


(ii)          Each
Debtor shall cause each wholly-owned Subsidiary that is organized in a jurisdiction within the United States to promptly become
a party hereto (an “Additional Debtor”), by executing and delivering an Additional Debtor Joinder in substantially
the form of Annex A attached hereto and comply with the provisions hereof applicable to the Debtors. Concurrent therewith,
the Additional Debtor shall deliver replacement schedules for, or supplements to all other Schedules to (or referred to in) this
Agreement, as applicable, which replacement schedules shall supersede, or supplements shall modify, the Schedules then in effect.
The Additional Debtor shall also deliver such opinions of counsel, authorizing resolutions, good standing certificates, incumbency
certificates, organizational documents, financing statements and other information and documentation as the Agent may reasonably
request. Upon delivery of the foregoing to the Agent, the Additional Debtor shall be and become a party to this Agreement with
the same rights and obligations as the Debtors, for all purposes hereof as fully and to the same extent as if it were an original
signatory hereto and shall be deemed to have made the representations, warranties and covenants set forth herein as of the date
of execution and delivery of such Additional Debtor Joinder, and all references herein to the “Debtors” shall be deemed
to include each Additional Debtor.


 






    	12



    	 



    

 


(jj)          Each
Debtor shall vote the Pledged Securities to comply with the covenants and agreements set forth herein and in the Secured Debt
Securities.


 


(kk)        Each
Debtor shall register the pledge of the applicable Pledged Securities on the books of such Debtor. Each Debtor shall notify each
issuer of Pledged Securities to register the pledge of the applicable Pledged Securities in the name of the Secured Parties on
the books of such issuer. Further, except with respect to certificated securities delivered to the Agent, the applicable Debtor
shall deliver to Secured Parties an acknowledgement of pledge (which, where appropriate, shall comply with the requirements of
the relevant UCC with respect to perfection by registration) signed by the issuer of the applicable Pledged Securities, which
acknowledgement shall confirm that: (a) it has registered the pledge on its books and records; and (b) at any time directed by
Secured Parties during the continuation of an Event of Default, such issuer will transfer the record ownership of such Pledged
Securities into the name of any designee of Secured Parties, will take such steps as may be necessary to effect the transfer,
and will comply with all other instructions of Secured Parties regarding such Pledged Securities without the further consent of
the applicable Debtor.


 


(ll)          In
the event that, upon an occurrence of an Event of Default, Secured Parties shall sell all or any of the Pledged Securities to
another party or parties (herein called the “Transferee”) or shall purchase or retain all or any of the Pledged
Securities, each Debtor shall, to the extent applicable: (i) deliver to the Secured Parties or the Transferee, as the case may
be, the articles of incorporation, bylaws, minute books, stock certificate books, corporate seals, deeds, leases, indentures,
agreements, evidences of indebtedness, books of account, financial records and all other Organizational Documents and records
of the Debtors and their direct and indirect subsidiaries; (ii) use its best efforts to obtain resignations of the persons then
serving as officers and directors of the Debtors and their direct and indirect subsidiaries, if so requested; and (iii) use its
best efforts to obtain any approvals that are required by any governmental or regulatory body in order to permit the sale of the
Pledged Securities to the Transferee or the purchase or retention of the Pledged Securities by the Secured Parties and allow the
Transferee or the Secured Parties to continue the business of the Debtors and their direct and indirect subsidiaries.


 


(mm)      Without
limiting the generality of the other obligations of the Debtors hereunder, each Debtor shall promptly (i) cause to be registered
at the United States Copyright Office all of its material copyrights, (ii) cause the security interest contemplated hereby with
respect to all Intellectual Property registered at the United States Copyright Office or United States Patent and Trademark Office
to be duly recorded at the applicable office, and (iii) give the Agent notice whenever it acquires (whether absolutely or by license)
or creates any additional material Intellectual Property on a quarterly basis.


 


(nn)          Each
Debtor will from time to time, at the joint and several expense of the Debtors, promptly execute and deliver all such further
instruments and documents, and take all such further action as the Secured Parties may reasonably request, in order to perfect
and protect any security interest granted or purported to be granted hereby or to enable the Secured Parties to exercise and enforce
their rights and remedies hereunder and with respect to any Collateral or to otherwise carry out the purposes of this Agreement.

(oo)          Schedule
4.(oo) attached hereto lists all of the patents, patent applications, trademarks, trademark applications, registered copyrights,
and domain names owned by any of the Debtors as of the date hereof. Schedule 4.(oo) lists all material licenses in favor
of any Debtor for the use of any patents, trademarks, copyrights and domain names as of the date hereof. All United States material
patents and trademarks of the Debtors have been duly recorded at the United States Patent and Trademark Office and all material
copyrights of the Debtors have been duly recorded at the United States Copyright Office.


 


(pp)          Except
as set forth on Schedule 4.(pp) attached hereto, none of the account debtors or other persons or entities obligated on
any of the Collateral is a governmental authority covered by the Federal Assignment of Claims Act or any similar federal, state
or local statute or rule in respect of such Collateral.


 


(qq)          Until
the Obligations shall have been paid and performed in full (other than inchoate indemnification obligations), the Company covenants
that it shall promptly cause any Additional Debtor to enter into a Subsidiary Guarantee in favor of the Secured Parties in the
form of Exhibit G to the Purchase Agreement.


 


5              Effect
of Pledge on Certain Rights. The parties hereto agree that, if any of the Collateral subject to this Agreement consists of
nonvoting equity or ownership interests (regardless of class, designation, preference or rights) that may be converted into voting
equity or ownership interests upon the occurrence of certain events (including, without limitation, upon the transfer of all or
any of the other stock or assets of the issuer), the pledge of such equity or ownership interests pursuant to this Agreement or
the enforcement of any of the Secured Parties’ rights hereunder shall not be deemed to be the type of event which would
trigger such conversion rights, notwithstanding any provisions in the Organizational Documents or agreements to which any Debtor
is subject or to which any Debtor is party.


 


6              Defaults.
The following events shall be “Events of Default”:


 


(a)          The
occurrence of an Event of Default under the Secured Debt Securities;


 


(b)          Any
representation or warranty of any Debtor in this Agreement shall prove to have been incorrect in any material respect when made;


 


(c)          The
failure by any Debtor to observe or perform any of its obligations hereunder for ten (10) days after delivery to such Debtor of
notice of such failure by or on behalf of any Secured Party unless such default is capable of cure but cannot be cured within
such time frame and such Debtor is all commercially reasonable efforts to cure same in a timely fashion; or


 


(d)          Any
provision of this Agreement is at any time for any reason declared to be null and void, any Debtor contests the validity or enforceability
of this Agreement, any Debtor governmental authority having jurisdiction over any Debtor commences any proceeding seeking to establish
the invalidity or unenforceability of this Agreement, or any Debtor denies that any Debtor has any liability or obligation purported
to be created under this Agreement.


 






    	14



    	 



    

 


7              Duty
To Hold In Trust.


 


(a)          Upon
the occurrence of any Event of Default and at any time thereafter that such Event of Default remains continuing, each Debtor shall,
upon receipt of any revenue, income, dividend, interest or other sums subject to the Security Interests, whether payable pursuant
to the Secured Debt Securities or otherwise, or of any check, draft, note, trade acceptance or other instrument evidencing an
obligation to pay any such sum, hold the same in trust for the Secured Parties and shall forthwith endorse and transfer any such
sums or instruments, or both, to the Secured Parties, pro rata in proportion to their respective then currently outstanding principal
amount of Secured Debt Securities, for application to the satisfaction of the Obligations (and if any Secured Debt Securities
are not outstanding, pro-rata in proportion to the initial purchases of the remaining Secured Debt Securities).


 


(b)          If
any Debtor shall become entitled to receive or shall receive any securities or other property (including, without limitation,
shares of Pledged Securities or instruments representing Pledged Securities acquired after the date hereof, or any options, warrants,
rights or other similar property or certificates representing a dividend, or any distribution in connection with any recapitalization,
reclassification or increase or reduction of capital, or issued in connection with any reorganization of such Debtor or any of
its direct or indirect subsidiaries) in respect of the Pledged Securities (whether as an addition to, in substitution of, or in
exchange for, such Pledged Securities or otherwise), such Debtor agrees to (i) accept the same as the agent of the Secured Parties;
(ii) hold the same in trust on behalf of and for the benefit of the Secured Parties; and (iii) to deliver any and all certificates
or instruments evidencing the same to Agent on or before the close of business on the fifth business day following the receipt
thereof by such Debtor, in the exact form received together with the Necessary Endorsements, to be held by Agent subject to the
terms of this Agreement as Collateral.


 


8              Rights
and Remedies Upon Default.


 


(a)          Upon
the occurrence of any Event of Default and at any time thereafter that such Event of Default remains continuing, the Secured Parties,
acting through the Agent, shall have the right to exercise all of the remedies conferred hereunder and under the Secured Debt
Securities, and the Secured Parties, shall have all the rights and remedies of a secured party under the UCC. Without limitation,
the Agent, for the benefit of the Secured Parties, shall have the following rights and powers:


 


i           The
Agent shall have the right to take possession of the Collateral and, for that purpose, enter, with the aid and assistance of any
person, any premises where the Collateral, or any part thereof, is or may be placed and remove the same, and each Debtor shall
assemble the Collateral and make it available to the Agent at places which the Agent shall reasonably select, whether at such
Debtor’s premises or elsewhere, and make available to the Agent, without rent, all of such Debtor’s respective premises
and facilities for the purpose of the Agent taking possession of, removing or putting the Collateral in saleable or disposable
form.


 


ii          Upon
notice to the Debtors by Agent, all rights of each Debtor to exercise the voting and other consensual rights which it would otherwise
be entitled to exercise and all rights of each Debtor to receive the dividends and interest which it would otherwise be authorized
to receive and retain, shall cease. Upon such notice, Agent shall have the right to receive, for the ratable benefit of the Secured
Parties, any interest, cash dividends or other payments on the Collateral and, at the option of Agent, to exercise in such Agent’s
discretion all voting rights pertaining thereto. Without limiting the generality of the foregoing, Agent shall have the right
(but not the obligation) to exercise all rights with respect to the Collateral as it were the sole and absolute owner thereof,
including, without limitation, to vote and/or to exchange, at its sole discretion, any or all of the Collateral in connection
with a merger, reorganization, consolidation, recapitalization or other readjustment concerning or involving the Collateral or
any Debtor or any of its direct or indirect subsidiaries.


 






    	15



    	 



    

 


iii          The
Agent shall have the right to use the Collateral and shall have the right to assign, sell, lease or otherwise dispose of and deliver
all or any part of the Collateral, at public or private sale or otherwise, either with or without special conditions or stipulations,
for cash or on credit or for future delivery, in such parcel or parcels and at such time or times and at such place or places,
and upon such terms and conditions as the Agent may deem commercially reasonable, all without (except as shall be required by
applicable statute and cannot be waived) advertisement or demand upon or notice to any Debtor or right of redemption of a Debtor,
which are hereby expressly waived. Upon each such sale, lease, assignment or other transfer of Collateral, the Agent, for the
ratable benefit of the Secured Parties, may, unless prohibited by applicable law which cannot be waived, purchase all or any part
of the Collateral being sold, free from and discharged of all trusts, claims, right of redemption and equities of any Debtor,
which are hereby waived and released.


 


iv         The
Agent shall have the right (but not the obligation) to notify any account debtors and any obligors under instruments or accounts
to make payments directly to the Agent, for the ratable benefit of the Secured Parties, and to enforce the Debtors’ rights
against such account debtors and obligors.


 


v          The
Agent may (but is not obligated to) direct any financial intermediary or any other person or entity holding any investment property
to transfer the same to the Agent (or the Agent’s designee), for the ratable benefit of the Secured Parties.


 


vi         The
Agent may (but is not obligated to) transfer any or all Intellectual Property registered in the name of any Debtor at the United
States Patent and Trademark Office and/or Copyright Office into the name of the Secured Parties or any designee or any purchaser
of any Collateral.


 






    	16



    	 



    

 


(b)          The
Agent shall comply with any applicable law in connection with a disposition of Collateral and such compliance will not be considered
adversely to affect the commercial reasonableness of any sale of the Collateral. The Agent may sell the Collateral without giving
any warranties and may specifically disclaim such warranties. If the Agent sells any of the Collateral on credit, the Debtors
will only be credited with payments actually made by the purchaser. In addition, each Debtor waives any and all rights that it
may have to a judicial hearing in advance of the enforcement of any of the Agent’s rights and remedies hereunder, including,
without limitation, its right following an Event of Default to take immediate possession of the Collateral and to exercise its
rights and remedies with respect thereto.


 


(c)          For
the purpose of enabling the Agent to further exercise rights and remedies under this Section 8 or elsewhere provided by agreement
or applicable law, each Debtor hereby grants to the Agent, for the ratable benefit of the Secured Parties an irrevocable, nonexclusive
license (exercisable without payment of royalty or other compensation to such Debtor) to use, license or sublicense following
an Event of Default, any Intellectual Property now owned or hereafter acquired by such Debtor, and wherever the same may be located,
and including in such license access to all media in which any of the licensed items may be recorded or stored and to all computer
software and programs used for the compilation or printout thereof.


 


(d)          Notwithstanding
anything in this Agreement to the contrary, each Secured Party agrees that it will not, and will not authorize the Agent to, exercise
any remedy provided for under this Agreement with respect to all or any portion of the Collateral unless such Secured Party is
a Permitted Secured Party (provided that the foregoing shall not prevent any Secured Party from commencing or participating in
any Insolvency Proceeding or taking any action (other than with respect to the Collateral) to enforce the payment or performance
of any Debtor’s obligations under any of the Secured Debt Securities or other Transaction Documents). This Section 8(d)
is not intended to confer any rights or benefits upon the Debtors, or any of them (other than pursuant to the last sentence
of this Section 8(d)), or any other Person except Secured Parties, and no Person (including any or all Debtors) other than
Secured Parties shall have any right to enforce any of the provisions of this Section 8(d) (other than pursuant to the
last sentence of this Section 8(d)). The Debtors, or any of them, may presume, conclusively, that any action that any Secured
Party takes under this Agreement has been authorized and approved by the other Secured Parties.


 


9              Applications
of Proceeds. The proceeds of any such sale, lease or other disposition of the Collateral hereunder or from payments made on
account of any insurance policy insuring any portion of the Collateral shall be applied first, to the expenses of retaking, holding,
storing, processing and preparing for sale, selling, and the like (including, without limitation, any taxes, fees and other costs
incurred in connection therewith) of the Collateral, to the reasonable attorneys’ fees and expenses incurred by the Agent
in enforcing the Secured Parties’ rights hereunder and in connection with collecting, storing and disposing of the Collateral,
and then to satisfaction of the Obligations pro rata among the Secured Parties (based on then-outstanding principal amounts of
Secured Debt Securities at the time of any such determination), and to the payment of any other amounts required by applicable
law, after which the Secured Parties shall pay to the applicable Debtor any surplus proceeds. If, upon the sale, license or other
disposition of the Collateral, the proceeds thereof are insufficient to pay all amounts to which the Secured Parties are legally
entitled, the Debtors will be liable for the deficiency, together with interest thereon, at the rate of 12% per annum or the lesser
amount permitted by applicable law (the “Default Rate”), and the reasonable fees of any attorneys employed
by the Secured Parties to collect such deficiency. To the extent permitted by applicable law, each Debtor waives all claims, damages
and demands against the Secured Parties arising out of the repossession, removal, retention or sale of the Collateral, unless
due solely to the gross negligence or willful misconduct of the Secured Parties as determined by a final judgment (not subject
to further appeal) of a court of competent jurisdiction.


 






    	17



    	 



    

 


10              Securities
Law Provision. Each Debtor recognizes that Secured Parties may be limited in their ability to effect a sale to the public
of all or part of the Pledged Securities by reason of certain prohibitions in the Securities Act of 1933, as amended, or other
federal or state securities laws (collectively, the “Securities Laws”), and may be compelled to resort to one
or more sales to a restricted group of purchasers who may be required to agree to acquire the Pledged Securities for their own
account, for investment and not with a view to the distribution or resale thereof. Each Debtor agrees that sales so made may be
at prices and on terms less favorable than if the Pledged Securities were sold to the public, and that the Secured Parties have
no obligation to delay the sale of any Pledged Securities for the period of time necessary to register the Pledged Securities
for sale to the public under the Securities Laws. Each Debtor shall cooperate with Secured Parties in its attempt to satisfy any
requirements under the Securities Laws (including, without limitation, registration thereunder if requested by Agent) applicable
to the sale of the Pledged Securities by Agent.


 


11              Costs
and Expenses. Each Debtor agrees to pay all reasonable out-of-pocket fees, costs and expenses incurred in connection with
any filing required hereunder, including without limitation, any financing statements pursuant to the UCC, continuation statements,
partial releases and/or termination statements related thereto or any expenses of any searches reasonably required by the Agent.
The Debtors will also, upon demand, pay to the Agent the amount of any and all reasonable expenses, including the reasonable fees
and expenses of its counsel, which the Agent, for the benefit of the Secured Parties, may incur in connection with the creation,
perfection, protection, foreclosure, collection or enforcement of the Security Interest and the preparation, administration, continuance,
amendment or enforcement of this Agreement and pay to the Agent the amount of any and all reasonable expenses, including the reasonable
fees and expenses of its counsel, which the Agent, for the benefit of the Secured Parties, and the Secured Parties may incur in
connection with (i) the enforcement of this Agreement, (ii) the custody or preservation of, or the sale of, collection from, or
other realization upon, any of the Collateral, or (iii) the exercise or enforcement of any of the rights of the Secured Parties
under the Secured Debt Securities. Until so paid, any fees payable hereunder shall be added to the principal amount of the Secured
Debt Securities and shall bear interest at the Default Rate.


 


12              Responsibility
for Collateral. The Debtors assume all liabilities and responsibility in connection with all Collateral, and the Obligations
shall in no way be affected or diminished by reason of the loss, destruction, damage or theft of any of the Collateral or its
unavailability for any reason. Without limiting the generality of the foregoing, (a) neither the Agent nor any Secured Party (i)
has any duty (either before or after an Event of Default) to collect any amounts in respect of the Collateral or to preserve any
rights relating to the Collateral, or (ii) has any obligation to clean-up or otherwise prepare the Collateral for sale, and (b)
each Debtor shall remain obligated and liable under each contract or agreement included in the Collateral to be observed or performed
by such Debtor thereunder. Neither the Agent nor any Secured Party shall have any obligation or liability under any such contract
or agreement by reason of or arising out of this Agreement or the receipt by the Agent or any Secured Party of any payment relating
to any of the Collateral, nor shall the Agent or any Secured Party be obligated in any manner to perform any of the obligations
of any Debtor under or pursuant to any such contract or agreement, to make inquiry as to the nature or sufficiency of any payment
received by the Agent or any Secured Party in respect of the Collateral or as to the sufficiency of any performance by any party
under any such contract or agreement, to present or file any claim, to take any action to enforce any performance or to collect
the payment of any amounts which may have been assigned to the Agent or to which the Agent or any Secured Party may be entitled
at any time or times.


 






    	18



    	 



    

 


13              Security
Interests Absolute. All rights of the Secured Parties and all of the Obligations are absolute and unconditional, irrespective
of: (a) any lack of validity or enforceability of this Agreement, the Secured Debt Securities or any agreement entered into in
connection with the foregoing, or any portion hereof or thereof; (b) any change in the time, manner or place of payment or performance
of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure
from the Secured Debt Securities or any other agreement entered into in connection with the foregoing; (c) any exchange, release
or nonperfection of any of the Collateral, or any release or amendment or waiver of or consent to departure from any other collateral
for, or any guarantee, or any other security, for all or any of the Obligations; (d) any action by the Secured Parties to obtain,
adjust, settle and cancel in its sole discretion any insurance claims or matters made or arising in connection with the Collateral;
or (e) any other circumstance which might otherwise constitute any legal or equitable defense available to a Debtor, or a discharge
of all or any part of the Security Interests granted hereby. Until the Obligations shall have been paid and performed in full
(other than inchoate indemnification obligations), the rights of the Secured Parties shall continue even if the Obligations are
barred for any reason, including, without limitation, the running of the statute of limitations or bankruptcy. Each Debtor expressly
waives presentment, protest, notice of protest, demand, notice of nonpayment and demand for performance. In the event that at
any time any transfer of any Collateral or any payment received by the Secured Parties hereunder shall be deemed by final order
of a court of competent jurisdiction to have been a voidable preference or fraudulent conveyance under the bankruptcy or insolvency
laws of the United States, or shall be deemed to be otherwise due to any party other than the Secured Parties, then, in any such
event, each Debtor’s obligations hereunder shall survive cancellation of this Agreement, and shall not be discharged or
satisfied by any prior payment thereof and/or cancellation of this Agreement, but shall remain a valid and binding obligation
enforceable in accordance with the terms and provisions hereof. Each Debtor waives all right to require the Secured Parties to
proceed against any other person or entity or to apply any Collateral which the Secured Parties may hold at any time, or to marshal
assets, or to pursue any other remedy.


 


14              Term
of Agreement. This Agreement and the Security Interests shall terminate on the date on which all payments under the Secured
Debt Securities have been paid in full and all other Obligations have been paid or discharged (other than inchoate indemnification
obligations); provided, however, that all indemnities of the Debtors contained in this Agreement (including, without
limitation, Annex B hereto) shall survive and remain operative and in full force and effect regardless of the termination of this
Agreement.

15             Power
of Attorney; Further Assurances.


 


(a)          Each
Debtor authorizes the Agent, and does hereby make, constitute and appoint the Agent and its officers, agents, successors or assigns
with full power of substitution, as such Debtor’s true and lawful attorney-in-fact, with power, in the name of the Agent
or such Debtor, to, after the occurrence and during the continuance of an Event of Default, (i) endorse any note, checks, drafts,
money orders or other instruments of payment (including payments payable under or in respect of any policy of insurance) in respect
of the Collateral that may come into possession of the Agent; (ii) to sign and endorse any financing statement pursuant to the
UCC or any invoice, freight or express bill, bill of lading, storage or warehouse receipts, drafts against debtors, assignments,
verifications and notices in connection with accounts, and other documents relating to the Collateral; (iii) to pay or discharge
taxes, liens, security interests or other encumbrances at any time levied or placed on or threatened against the Collateral; (iv)
to demand, collect, receipt for, compromise, settle and sue for monies due in respect of the Collateral; (v) to transfer any Intellectual
Property or provide licenses respecting any Intellectual Property; and (vi) generally, at the option of the Agent, and at the
expense of the Debtors, at any time, or from time to time, to execute and deliver any and all documents and instruments and to
do all acts and things which the Agent deems necessary to protect, preserve and realize upon the Collateral and the Security Interests
granted therein in order to effect the intent of this Agreement and the Secured Debt Securities all as fully and effectually as
the Debtors might or could do; and each Debtor hereby ratifies all that said attorney shall lawfully do or cause to be done by
virtue hereof. This power of attorney is coupled with an interest and shall be irrevocable for the term of this Agreement and
thereafter as long as any of the Obligations (other than inchoate indemnification obligations) shall be outstanding. The designation
set forth herein shall be deemed to amend and supersede any inconsistent provision in the Organizational Documents or other documents
or agreements to which any Debtor is subject or to which any Debtor is a party. Without limiting the generality of the foregoing,
after the occurrence and during the continuance of an Event of Default, each Secured Party is specifically authorized to execute
and file any applications for or instruments of transfer and assignment of any patents, trademarks, copyrights or other Intellectual
Property with the United States Patent and Trademark Office and the United States Copyright Office.


 


(b)          On
a continuing basis, each Debtor will make, execute, acknowledge, deliver, file and record, as the case may be, with the proper
filing and recording agencies in any jurisdiction, including, without limitation, the jurisdictions indicated on Schedule 4.(y) attached hereto, all such instruments, and take all such action as may reasonably be requested by the Agent, to perfect the
Security Interests granted hereunder and otherwise to carry out the intent and purposes of this Agreement, or for assuring and
confirming to the Agent the grant or perfection of a perfected security interest in all the Collateral under the UCC.


 


(c)          Each
Debtor hereby irrevocably appoints the Agent as such Debtor’s attorney-in-fact, with full authority in the place and instead
of such Debtor and in the name of such Debtor, from time to time in the Agent’s discretion, to take any action and to execute
any instrument which the Agent may deem necessary or advisable to accomplish the purposes of this Agreement, including the filing,
in its sole discretion, of one or more financing or continuation statements and amendments thereto, relative to any of the Collateral
without the signature of such Debtor where permitted by law, which financing statements may (but need not) describe the Collateral
as “all assets” or “all personal property” or words of like import, and ratifies all such actions taken
by the Agent. This power of attorney is coupled with an interest and shall be irrevocable for the term of this Agreement and thereafter
as long as any of the Obligations shall be outstanding.

All notices, requests, demands and other communications hereunder shall be subject to the notice provision of the Purchase Agreement.


 


17             Other
Security. To the extent that the Obligations are now or hereafter secured by property other than the Collateral or by the
guarantee, endorsement or property of any other person, firm, corporation or other entity, then the Agent shall have the right,
in its sole discretion, to pursue, relinquish, subordinate, modify or take any other action with respect thereto, without in any
way modifying or affecting any of the Secured Parties’ rights and remedies hereunder.


 


18             Appointment
of Agent. The Secured Parties hereby appoint Broadfin Capital, LLC (“Broadfin”) to act as their agent (in such
capacity, the “Agent”) for purposes of exercising any and all rights and remedies of the Secured Parties hereunder.

appoint a new Agent, provided that Broadfin may not be removed as Agent unless Broadfin Healthcare Master Fund, Ltd. then holds
less than $1,000,000 in principal amount of Secured Debt Securities; provided, further, that such removal may occur
only if the other Secured Parties then hold, in the aggregate, not less than an aggregate of $1,000,000 in principal amount of
Secured Debt Securities. The Agent has the rights, responsibilities and immunities set forth in Annex A hereto.


 


19             Miscellaneous.


 


(a)          No
course of dealing between the Debtors, on the one hand, and the Secured Parties, on the other hand, nor any failure to exercise,
nor any delay in exercising, on the part of the Secured Parties, any right, power or privilege hereunder or under the Secured
Debt Securities shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder
or thereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege.


 


(b)          All
of the rights and remedies of the Secured Parties with respect to the Collateral, whether established hereby or by the Secured
Debt Securities or by any other agreements, instruments or documents or by law shall be cumulative and may be exercised singly
or concurrently.


 


(c)          This
Agreement, together with the exhibits and schedules hereto, contain the entire understanding of the parties with respect to the
subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which
the parties acknowledge have been merged into this Agreement and the exhibits and schedules hereto. No provision of this Agreement
may be waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Debtors
and the Secured Parties holding 67% or more of the principal amount of Secured Debt Securities then outstanding, or, in the case
of a waiver, by the party against whom enforcement of any such waived provision is sought; provided, however, unanimous
consent shall be required for any amendment that would adversely affect any Secured Parties.


 






    	21



    	 



    

 


(d)          If
any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that
they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.


 


(e)          No
waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing
waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof,
nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.


 


(f)          This
Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted assigns. No Debtor
may assign this Agreement or any rights or obligations hereunder without the prior written consent of each Secured Party (other
than by merger). Any Secured Party may assign any or all of its rights under this Agreement to any Person (as defined in the Purchase
Agreement) to whom such Secured Party assigns or transfers any Obligations, provided such transferee agrees in writing to be bound,
with respect to the transferred Obligations, by the provisions of this Agreement that apply to the “Secured Parties.”


 


(g)          Each
party shall take such further action and execute and deliver such further documents as may be necessary or appropriate in order
to carry out the provisions and purposes of this Agreement.


 


(h)          Except
to the extent mandatorily governed by the jurisdiction or situs where the Collateral is located, all questions concerning the
construction, validity, enforcement and interpretation of this Agreement 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 conflicts of law thereof. Except to the extent
mandatorily governed by the jurisdiction or situs where the Collateral is located, each Debtor agrees that all proceedings concerning
the interpretations, enforcement and defense of the transactions contemplated by this Agreement and the Secured Debt Securities
(whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees
or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York, Borough of Manhattan.
Except to the extent mandatorily governed by the jurisdiction or situs where the Collateral is located, each Debtor hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for
the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein,
and hereby irrevocably waives, and agrees not to assert in any proceeding, any claim that it is not personally subject to the
jurisdiction of any such court, that such proceeding is improper. Each party hereto hereby irrevocably waives personal service
of process and consents to process being served in any such proceeding by mailing a copy thereof via registered or certified mail
or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any manner permitted by 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 Agreement or the transactions contemplated hereby.


 






    	22



    	 



    

 


(i)          This
Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and,
all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile
transmission, such signature shall create a valid binding obligation of the party executing (or on whose behalf such signature
is executed) the same with the same force and effect as if such facsimile signature were the original thereof.


 


(j)          All
Debtors shall jointly and severally be liable for the obligations of each Debtor to the Secured Parties hereunder.


 


(k)          Each
Debtor shall indemnify, reimburse and hold harmless the Agent and the Secured Parties and their respective partners, members,
shareholders, officers, directors, employees and agents (and any other persons with other titles that have similar functions)
(collectively, “Indemnitees”) from and against any and all losses, claims, liabilities, damages, penalties,
suits, costs and expenses, of any kind or nature, (including fees relating to the cost of investigating and defending any of the
foregoing) imposed on, incurred by or asserted against such Indemnitee in any way related to or arising from or alleged to arise
from this Agreement or the Collateral, except any such losses, claims, liabilities, damages, penalties, suits, costs and expenses
which result from the gross negligence or willful misconduct of the Indemnitee as determined by a final, nonappealable decision
of a court of competent jurisdiction. This indemnification provision is in addition to, and not in limitation of, any other indemnification
provision in the Secured Debt Securities, the Purchase Agreement or any other agreement, instrument or other document executed
or delivered in connection herewith or therewith.


 


(l)          Nothing
in this Agreement shall be construed to subject Agent or any Secured Party to liability as a partner in any Debtor or any of its
direct or indirect subsidiaries that is a partnership or as a member in any Debtor or any of its direct or indirect subsidiaries
that is a limited liability company, nor shall Agent or any Secured Party be deemed to have assumed any obligations under any
partnership agreement or limited liability company agreement, as applicable, of any such Debtor or any of its direct or indirect
subsidiaries or otherwise, unless and until the any such Secured Party exercises its right to be substituted for such Debtor as
a partner or member, as applicable, pursuant hereto.


 






    	23



    	 



    

 


(m)          To
the extent that the grant of the security interest in the Collateral and the enforcement of the terms hereof require the consent,
approval or action of any partner or member, as applicable, of any Debtor or any direct or indirect subsidiary of any Debtor or
compliance with any provisions of any of the Organizational Documents, the Debtors hereby grant such consent and approval and
waive any such noncompliance with the terms of said documents.

ANNEX B

to

SECURITY

AGREEMENT


 


THE AGENT


 


1             Appointment. The Secured Parties
(all capitalized terms used herein and not otherwise defined shall have the respective meanings provided in the Amended and Restated
Security Agreement to which this Annex B is attached (the “Agreement”)), by their acceptance of the benefits
of the Agreement, hereby designate Broadfin Capital, LLC (“Broadfin”) as the Agent to act as specified herein
and in the Agreement. Each Secured Party shall be deemed irrevocably to authorize the Agent to take such action on its behalf under
the provisions of the Agreement and any other Transaction Document (as such term is defined in the Purchase Agreement) and to exercise
such powers and to perform such duties hereunder and thereunder as are specifically delegated to or required of the Agent by the
terms hereof and thereof and such other powers as are reasonably incidental thereto. The Agent may perform any of its duties hereunder
by or through its agents or employees.


 


2             Nature of Duties. The Agent shall
have no duties or responsibilities except those expressly set forth in the Agreement. Neither the Agent nor any of its partners,
members, shareholders, officers, directors, employees or agents shall be liable for any action taken or omitted by it as such under
the Agreement or hereunder or in connection herewith or therewith, be responsible for the consequence of any oversight or error
of judgment or answerable for any loss, unless caused solely by its or their gross negligence or willful misconduct as determined
by a final judgment (not subject to further appeal) of a court of competent jurisdiction. The duties of the Agent shall be mechanical
and administrative in nature; the Agent shall not have by reason of the Agreement or any other Transaction Document a fiduciary
relationship in respect of any Debtor or any Secured Party; and nothing in the Agreement or any other Transaction Document, expressed
or implied, is intended to or shall be so construed as to impose upon the Agent any obligations in respect of the Agreement or
any other Transaction Document except as expressly set forth herein and therein.


 


3             Lack of Reliance on the Agent. Independently
and without reliance upon the Agent, each Secured Party, to the extent it deems appropriate, has made and shall continue to make
(i) its own independent investigation of the financial condition and affairs of the Company and its subsidiaries in connection
with such Secured Party’s investment in the Debtors, the creation and continuance of the Obligations, the transactions contemplated
by the Transaction Documents, and the taking or not taking of any action in connection therewith, and (ii) its own appraisal of
the creditworthiness of the Company and its subsidiaries, and of the value of the Collateral from time to time, and the Agent shall
have no duty or responsibility, either initially or on a continuing basis, to provide any Secured Party with any credit, market
or other information with respect thereto, whether coming into its possession before any Obligations are incurred or at any time
or times thereafter. The Agent shall not be responsible to the Debtors or any Secured Party for any recitals, statements, information,
representations or warranties herein or in any document, certificate or other writing delivered in connection herewith, or for
the execution, effectiveness, genuineness, validity, enforceability, perfection, collectability, priority or sufficiency of the
Agreement or any other Transaction Document, or for the financial condition of the Debtors or the value of any of the Collateral,
or be required to make any inquiry concerning either the performance or observance of any of the terms, provisions or conditions
of the Agreement or any other Transaction Document, or the financial condition of the Debtors, or the value of any of the Collateral,
or the existence or possible existence of any default or Event of Default under the Agreement, the Debentures or any of the other
Transaction Documents.


 



    	 



    	 



    
 

4              Certain Rights of the Agent. The
Agent shall have the right to take any action with respect to the Collateral, on behalf of all of the Secured Parties. To the extent
practical, the Agent shall request instructions from the Secured Parties with respect to any material act or action (including
failure to act) in connection with the Agreement or any other Transaction Document, and shall be entitled to act or refrain from
acting in accordance with the instructions of a Majority in Interest; if such instructions are not provided despite the Agent’s
request therefor, the Agent shall be entitled to refrain from such act or taking such action, and if such action is taken, shall
be entitled to appropriate indemnification from the Secured Parties in respect of actions to be taken by the Agent; and the Agent
shall not incur liability to any person or entity by reason of so refraining. Without limiting the foregoing, (a) no Secured Party
shall have any right of action whatsoever against the Agent as a result of the Agent acting or refraining from acting hereunder
in accordance with the terms of the Agreement or any other Transaction Document, and the Debtors shall have no right to question
or challenge the authority of, or the instructions given to, the Agent pursuant to the foregoing and (b) the Agent shall not be
required to take any action which the Agent believes (is) could reasonably be expected to expose it to personal liability or (ii)
is contrary to this Agreement, the Transaction Documents or applicable law.


 


5              Reliance. The Agent shall be entitled
to rely, and shall be fully protected in relying, upon any writing, resolution, notice, statement, certificate, telex, e-mail or
telecopy message, cablegram, radiogram, order or other document or telephone message signed, sent or made by the proper person
or entity, and, with respect to all legal matters pertaining to the Agreement and the other Transaction Documents and its duties
thereunder, upon advice of counsel selected by it and upon all other matters pertaining to this Agreement and the other Transaction
Documents and its duties thereunder, upon advice of other experts selected by it. Anything to the contrary notwithstanding, the
Agent shall have no obligation whatsoever to any Secured Party to assure that the Collateral exists or is owned by the Debtors
or is cared for, protected or insured or that the liens granted pursuant to the Agreement have been properly or sufficiently or
lawfully created, perfected, or enforced or are entitled to any particular priority.


 


6              Indemnification. To the extent that
the Agent is not reimbursed and indemnified by the Debtors, the Secured Parties will jointly and severally reimburse and indemnify
the Agent, in proportion to their principal amounts of Debentures then held, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which
may be imposed on, incurred by or asserted against the Agent in performing its duties hereunder or under the Agreement or any other
Transaction Document, or in any way relating to or arising out of the Agreement or any other Transaction Document except for those
determined by a final judgment (not subject to further appeal) of a court of competent jurisdiction to have resulted solely from
the Agent’s own gross negligence or willful misconduct. Prior to taking any action hereunder as Agent, the Agent may require
each Secured Party to deposit with it sufficient sums as it determines in good faith is necessary to protect the Agent for costs
and expenses associated with taking such action.


 



    	2



    	 



    
 

7              Resignation by the Agent.


 


(a)          The
Agent may resign from the performance of all its functions and duties under the Agreement and the other Transaction Documents at
any time by giving 30 days’ prior written notice (as provided in the Agreement) to the Debtors and the Secured Parties. Such
resignation shall take effect upon the appointment of a successor Agent pursuant to clauses (b) and (c) below.


 


(b)          Upon
any such notice of resignation, the Secured Parties, acting by a Majority in Interest, shall appoint a successor Agent hereunder.


 


(c)          If
a successor Agent shall not have been so appointed within said 30-day period, the Agent shall then appoint a successor Agent who
shall serve as Agent until such time, if any, as the Secured Parties appoint a successor Agent as provided above. If a successor
Agent has not been appointed within such 30-day period, the Agent may petition any court of competent jurisdiction or may interplead
the Debtors and the Secured Parties in a proceeding for the appointment of a successor Agent, and all fees, including, but not
limited to, extraordinary fees associated with the filing of interpleader and expenses associated therewith, shall be payable by
the Debtors on demand.


 


8             Rights with respect to Collateral.
Each Secured Party agrees with all other Secured Parties and the Agent (i) that it shall not, and shall not attempt to, exercise
any rights with respect to its security interest in the Collateral, whether pursuant to any other agreement or otherwise (other
than pursuant to this Agreement), or take or institute any action against the Agent or any of the other Secured Parties in respect
of the Collateral or its rights hereunder (other than any such action arising from the breach of this Agreement) and (ii) that
such Secured Party has no other rights with respect to the Collateral other than as set forth in this Agreement and the other Transaction
Documents. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent and the retiring Agent shall
be discharged from its duties and obligations under the Agreement. After any retiring Agent’s resignation or removal hereunder
as Agent, the provisions of the Agreement including this Annex B shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Agent.

    	2



    	 



    

 


3              Transaction Documents. This Agreement
has been entered into pursuant to and in conjunction with the Purchase Agreement. The provisions of the Purchase Agreement shall
supersede and control over any conflicting or inconsistent provision herein. The rights and remedies of the Secured Parties with
respect to the Intellectual Property Collateral are as provided by the Transaction Documents (as defined in the Purchase Agreement),
and nothing in this Agreement shall be deemed to limit such rights and remedies.


 


4              Execution in Counterparts. This Agreement
may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an
original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature

party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York,
Borough of Manhattan 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 this Agreement), 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 any such court,
that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably
waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy
thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect
for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted
by law. If either party shall commence an action, suit or proceeding to enforce any provisions of this Agreement, then, in addition
to the obligations of the Company under the Purchase Agreement, the prevailing party in such action, suit or proceeding shall be
reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation,
