of [BUYER] or its registered assigns (“Holder”) the amount set out above as the Original Principal Amount (as
reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the “Principal”) when
due, whether upon the Maturity Date, on any Installment Date with respect to the Installment Amount due on such Installment Date
(each as defined below), or upon acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to
pay interest (“Interest”) on any outstanding Principal at the applicable Interest Rate (as defined below) from
the date set out above as the Issuance Date (the “Issuance Date”) until the same becomes due and payable,
whether upon the Maturity Date, on any Installment Date with respect to the Installment Amount due on such Installment Date, or
upon acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Senior Convertible
Note (including all Senior Convertible Notes issued in exchange, transfer or replacement hereof, this “Note”)
is one of an issue of Senior Convertible Notes issued pursuant to the Securities Purchase Agreement (as defined below) on the Closing
Date (as defined below) (collectively, the “Notes”, and such other Senior Convertible Notes, the “Other
Notes”). Certain capitalized terms used herein are defined in Section 29.

 

    	 

    	 

    

 

1.            PAYMENTS
OF PRINCIPAL. On each Installment Date, the Company shall pay to the Holder an amount equal to the Installment Amount due on
such Installment Date in accordance with Section 8. On the Maturity Date, the Company shall pay to the Holder an amount in cash
(excluding any amounts paid in shares of Common Stock on the Maturity Date in accordance with Section 8) representing all outstanding
Principal, accrued and unpaid Interest and accrued and unpaid Late Charges (as defined in Section 23(b)) on such Principal and
Interest. Other than as specifically permitted by this Note, the Company may not prepay any portion of the outstanding Principal,
accrued and unpaid Interest or accrued and unpaid Late Charges on Principal and Interest, if any.

 

2.            INTEREST;
INTEREST RATE.

 

(a)          Interest
on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 360-day year and twelve 30-day
months and shall be payable in arrears on each Installment Date (each, an “Interest Date”) and shall
compound each month and shall be payable in accordance with the terms of this Note. Interest shall be payable on each Interest
Date prior to the initial Installment Date in cash and, thereafter, Interest shall be paid on each Installment Date occurring on
an Interest Date in accordance with Section 8 as part of the applicable Installment Amount due on the applicable Interest Date.

 

(b)          Prior
to the payment of Interest on an Interest Date, Interest on this Note shall accrue at the Interest Rate and be payable by
way of inclusion of the Interest in the Conversion Amount on each Conversion Date in accordance with Section 3(b)(i)
or upon any redemption in accordance with Section 11. From and after the occurrence and during the continuance of any Event of
Default, the Interest Rate shall automatically be increased to eighteen percent (18.0%) per annum. In the event that such Event
of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be effective as of the calendar
day immediately following the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during
the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such
Event of Default through and including the date of such cure of such Event of Default.

 

3.            CONVERSION
OF NOTES. This Note shall be convertible into validly issued, fully paid and non-assessable shares of Common Stock (as defined
below), on the terms and conditions set forth in this Section 3.

 

(a)          Conversion
Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder shall be entitled
to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into validly issued, fully paid and non-assessable
shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue
any fraction of a share of Common Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share
of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall
pay any and all transfer, stamp, issuance and similar taxes that may be payable with respect to the issuance and delivery of Common
Stock upon conversion of any Conversion Amount.

 

    	2

    	 

    

 

(b)          Conversion
Rate. The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall
be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

 

(i)          “Conversion
Amount” means the sum of (x) portion of the Principal to be converted, redeemed or otherwise with respect to which this
determination is being made, (y) all accrued and unpaid Interest with respect to such portion of the
Principal amount and accrued and unpaid Late Charges with respect to such portion of such Principal and such Interest and (z) the
applicable Make-Whole Amount.

 

(ii)         “Conversion
Price” means, as of any Conversion Date or other date of determination, $0.264, subject to adjustment as provided herein.

 

(c)          Mechanics
of Conversion.

 

(i)          Optional
Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”),
the Holder shall deliver (whether via facsimile or otherwise), for receipt on or prior to 11:59 p.m., New York time, on such date,
a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the “Conversion Notice”)
to the Company. If required by Section 3(c)(iii), within three (3) Trading Days following a conversion of this Note as aforesaid,
the Holder shall surrender this Note to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification
undertaking with respect to this Note in the case of its loss, theft or destruction as contemplated by Section 17(b)). On or before
the first (1st) Trading Day following the date of receipt of a Conversion Notice, the Company shall transmit by facsimile an acknowledgment
of confirmation, in the form attached hereto as Exhibit II, of receipt of such Conversion Notice to the Holder and the Company’s
transfer agent (the “Transfer Agent”) . On or before the third (3rd) Trading Day following the date of receipt
of a Conversion Notice, the Company shall (1) provided that the Transfer Agent is participating in The Depository Trust Company’s
(“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of shares of Common Stock to
which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal
at Custodian system or (2) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue
and deliver (via reputable overnight courier) to the address as specified in the Conversion Notice, a certificate, registered in
the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled. If this
Note is physically surrendered for conversion pursuant to Section 3(c)(iii) and the outstanding Principal of this Note is greater
than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event
later than five (5) Business Days after receipt of this Note and at its own expense, issue and deliver to the Holder (or its designee)
a new Note (in accordance with Section 17(d)) representing the outstanding Principal not converted. The Person or Persons entitled
to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder
or holders of such shares of Common Stock on the Conversion Date. In the event of a partial conversion of this Note pursuant hereto,
the Principal amount converted shall be deducted from the Installment Amount(s) relating to the Installment Date(s) as set forth
in the applicable Conversion Notice.

 

    	3

    	 

    

 

(ii)         Company’s
Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, to issue to the Holder within three
(3) Trading Days after the Company’s receipt of a Conversion Notice (whether via facsimile or otherwise) (the “Share
Delivery Deadline”), a certificate for the number of shares of Common Stock to which the Holder is entitled and register
such shares of Common Stock on the Company’s share register or to credit the Holder’s or its designee’s balance
account with DTC for such number of shares of Common Stock to which the Holder is entitled upon the Holder’s conversion of
any Conversion Amount (as the case may be) (a “Conversion Failure”) then, in addition to all other remedies
available to the Holder, (1) the Company shall pay in cash to the Holder on each day after such Share Delivery Deadline that the
issuance of such shares of Common Stock is not timely effected an amount equal to 1% per month of the product of (A) the sum of
the number of shares of Common Stock not issued to the Holder on a timely basis and to which the Holder is entitled multiplied
by (B) the Closing Sale Price of the Common Stock on the Trading Day immediately preceding the last possible date which the Company
could have issued such shares of Common Stock to the Holder without violating Section 3(c)(i) and (2) the Holder, upon written
notice to the Company, may void its Conversion Notice with respect to, and retain or have returned (as the case may be) any portion
of this Note that has not been converted pursuant to such Conversion Notice, provided that the voiding of a Conversion Notice shall
not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to
this Section 3(c)(ii) or otherwise. In addition to the foregoing, if on or prior to the Share Delivery Deadline, the Company shall
fail to issue and deliver a certificate to the Holder and register such shares of Common Stock on the Company’s share register
or credit the Holder’s or its designee’s balance account with DTC for the number of shares of Common Stock to which
the Holder is entitled upon the Holder’s conversion hereunder (as the case may be), and if on or after such Share Delivery
Deadline the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of
a sale by the Holder of all or any portion of the number of shares of Common Stock, or a sale of a number of shares of Common Stock
equal to all or any portion of the number of shares of Common Stock, issuable upon such conversion that the Holder so anticipated
receiving from the Company, then, in addition to all other remedies available to the Holder, the Company shall, within three (3)
Business Days after receipt of the Holder’s written request and in the Holder’s discretion, either: (i) pay cash to
the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket
expenses, if any) for the shares of Common Stock so purchased (including, without limitation, by any other Person in respect, or
on behalf, of the Holder) (the “Buy-In Price”), at which point the Company’s obligation to so issue and
deliver such certificate or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which
the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) (and to issue such shares of Common Stock)
shall terminate, or (ii) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing
such shares of Common Stock or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which
the Holder is entitled upon the Holder’s conversion hereunder (as the case may be) and pay cash to the Holder in an amount
equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock multiplied by (B)
the lowest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable
Conversion Notice and ending on the date of such issuance and payment under this clause (ii).

 

    	4

    	 

    

 

(iii)        Registration;
Book-Entry. The Company shall maintain a register (the “Register”) for the recordation of the names and
addresses of the holders of each Note and the principal amount of the Notes and Restricted Principal held by such holders held
by such holders (the “Registered Notes”). The entries in the Register shall be conclusive and binding for all
purposes absent manifest error. The Company and the holders of the Notes shall treat each Person whose name is recorded in the
Register as the owner of a Note for all purposes (including, without limitation, the right to receive payments of Principal and
Interest hereunder) notwithstanding notice to the contrary. A Registered Note may be assigned, transferred or sold in whole or
in part only by registration of such assignment or sale on the Register. Upon its receipt of a written request to assign, transfer
or sell all or part of any Registered Note by the holder thereof, the Company shall record the information contained therein in
the Register and issue one or more new Registered Notes in the same aggregate principal amount as the principal amount of the surrendered
Registered Note to the designated assignee or transferee pursuant to Section 17, provided that if the Company does not so
record an assignment, transfer or sale (as the case may be) of all or part of any Registered Note within two (2) Business Days
of its receipt of such a request, then the Register shall be automatically updated to reflect such assignment, transfer or sale
(as the case may be). Notwithstanding anything to the contrary set forth in this Section 3, following conversion of any portion
of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company
unless (A) the full Conversion Amount represented by this Note is being converted (in which event this Note shall be delivered
to the Company following conversion thereof as contemplated by Section 3(c)(i)) or (B) the Holder has provided the Company with
prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender
of this Note. The Holder and the Company shall maintain records showing the Principal, Interest and Late Charges converted and/or
paid (as the case may be) or Restricted Principal becoming unrestricted and the dates of such conversions, Control Account Release
(as defined below) and/or payments (as the case may be) or shall use such other method, reasonably satisfactory to the Holder and
the Company, so as not to require physical surrender of this Note upon conversion. If the Company does not update the Register
to record such Principal, Interest and Late Charges converted and/or paid (as the case may be) or Restricted Principal becoming
unrestricted] and the dates of such conversions, Control Account Release and/or payments (as the case may be) within two (2) Business
Days of such occurrence, then the Register shall be automatically updated to reflect such occurrence.

(iv)         Pro
Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one holder of Notes for
the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion,
the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have Notes converted on such date a pro
rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted
for conversion on such date by such holder relative to the aggregate principal amount of all Notes submitted for conversion on
such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion
of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute
in accordance with Section 22.

 

(d)          Limitations
on Conversions. Notwithstanding anything to the contrary contained in this Note, this Note shall not be convertible by the
Holder hereof, and the Company shall not effect any conversion of this Note or otherwise issue any shares of Common Stock pursuant
hereto, to the extent (but only to the extent) that after giving effect to such conversion or other share issuance hereunder the
Holder (together with its affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of
the Common Stock. To the extent the above limitation applies, the determination of whether this Note shall be convertible
(vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of
which such securities shall be convertible, exercisable or exchangeable (as among all such securities owned by the Holder and its
affiliates) shall, subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company
for conversion, exercise or exchange (as the case may be). No prior inability to convert this Note, or to issue shares of Common
Stock, pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to
any subsequent determination of convertibility. For purposes of this paragraph, beneficial ownership and all determinations and
calculations (including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance
with Section 13(d) of the 1934 Act (as defined in the Securities Purchase Agreement) and the rules and regulations promulgated
thereunder. The provisions of this paragraph shall be implemented in a manner otherwise than in strict conformity with the terms
of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum
Percentage beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly
give effect to such Maximum Percentage limitation. The limitations contained in this paragraph shall apply to a successor Holder
of this Note. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not waive this
paragraph without the consent of holders of a majority of its Common Stock. For any reason at any time, upon the written or oral
request of the Holder, the Company shall within two (2) Business Days confirm orally and in writing to the Holder the number of
shares of Common Stock then outstanding, including by virtue of any prior conversion or exercise of convertible or exercisable
securities into Common Stock, including, without limitation, pursuant to this Note or securities issued pursuant to the Securities
Purchase Agreement. By written notice to the Company, at any time the Holder may increase or decrease the Maximum Percentage to
any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective
until the 61st day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the
Holder sending such notice and not to any other holder of Notes.

to redeem (regardless of whether such Event of Default has been cured) all or any portion of this Note by delivering written notice
thereof (the “Event of Default Redemption Notice”) to the Company, which Event of Default Redemption Notice
shall indicate the portion of this Note the Holder is electing to redeem. Each portion of this Note subject to redemption by the
Company pursuant to this Section 4(b) shall be redeemed by the Company at a price equal to the greater of (i) the product of (A)
the Conversion Amount to be redeemed multiplied by (B) the Redemption Premium and (ii) the product of (X) the Conversion Rate with
respect to the Conversion Amount in effect at such time as the Holder delivers an Event of Default Redemption Notice multiplied
by (Y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date immediately
preceding such Event of Default and ending on the date the Company makes the entire payment required to be made under this Section
4(b) (the “Event of Default Redemption Price”). Redemptions required by this Section 4(b) shall be made
in accordance with the provisions of Section 11. To the extent redemptions required by this Section 4(b) are deemed or determined
by a court of competent jurisdiction to be prepayments of this Note by the Company, such redemptions shall be deemed to be voluntary
prepayments. Notwithstanding anything to the contrary in this Section 4, but subject to Section 3(d), until the Event of Default
Redemption Price (together with any Late Charges thereon) is paid in full, the Conversion Amount submitted for redemption under
this Section 4(b) (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock
pursuant to the terms of this Note. In the event of a partial redemption of this Note pursuant hereto, the Principal amount redeemed
shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s) as set forth in the Event of Default
Redemption Notice. In the event of the Company’s redemption of any portion of this Note under this Section 4(b), the Holder’s
damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and
the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly, any redemption
premium due under this Section 4(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s
actual loss of its investment opportunity and not as a penalty.

5.            RIGHTS
UPON FUNDAMENTAL TRANSACTION.

 

(a)          Assumption.
The Company shall not enter into or be party to a Fundamental Transaction unless (i) the Successor Entity assumes in writing
all of the obligations of the Company under this Note and the other Transaction Documents in accordance with the provisions of
this Section 5(a) pursuant to written agreements in form and substance satisfactory to the Holder and approved by the Holder prior
to such Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security
of the Successor Entity evidenced by a written instrument substantially similar in form and substance to the Notes, including,
without limitation, having a principal amount and interest rate equal to the principal amounts then outstanding and the interest
rates of the Notes held by such holder, having similar conversion rights as the Notes and having similar ranking to the Notes,
and satisfactory to the Holder and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation
whose common stock is quoted on or listed for trading on an Eligible Market. Upon the occurrence of any 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 Note 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 Note and the other Transaction Documents with the same effect as if such Successor Entity had been named as the Company
herein. Upon consummation of a Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there
shall be issued upon conversion or redemption of this Note at any time after the consummation of such Fundamental Transaction,
in lieu of the shares of the Company’s Common Stock (or other securities, cash, assets or other property (except such items
still issuable under Sections 6 and 14, which shall continue to be receivable thereafter) issuable upon the conversion or redemption
of the Notes prior to such Fundamental Transaction, such shares of the publicly traded common stock (or their equivalent) of the
Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the happening of such
Fundamental Transaction had this Note been converted immediately prior to such Fundamental Transaction (without regard to any limitations
on the conversion of this Note), as adjusted in accordance with the provisions of this Note. Notwithstanding the foregoing, the
Holder may elect, at its sole option, by delivery of written notice to the Company to waive this Section 5(a) to permit the Fundamental
Transaction without the assumption of this Note. The provisions of this Section 5 shall apply similarly and equally to successive
Fundamental Transactions and shall be applied without regard to any limitations on the conversion of this Note.

 

    	12

    	 

    

 

(b)          Notice
of a Change of Control; Redemption Right. No sooner than twenty (20) Trading Days nor later than ten (10) Trading Days prior
to the consummation of a Change of Control (the “Change of Control Date”), but not prior to the public announcement
of such Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a
“Change of Control Notice”). At any time during the period beginning after the Holder’s receipt
of a Change of Control Notice or the Holder becoming aware of a Change of Control if a Change of Control Notice is not delivered
to the Holder in accordance with the immediately preceding sentence (as applicable) and ending on the later of twenty (20) Trading
Days after (A) consummation of such Change of Control or (B) the date of receipt of such Change of Control Notice, the Holder may
require the Company to redeem all or any portion of this Note by delivering written notice thereof (“Change of Control
Redemption Notice”) to the Company, which Change of Control Redemption Notice shall indicate the Conversion Amount the
Holder is electing to redeem. The portion of this Note subject to redemption pursuant to this Section 5 shall be redeemed by the
Company in cash at a price equal to the greatest of (i) the product of (w) the Change of Control Redemption Premium multiplied
by (y) the Conversion Amount being redeemed, (ii) the product of (x) the Change of Control Redemption Premium multiplied by (y)
the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient determined by dividing (I) the greatest
Closing Sale Price of the shares of Common Stock during the period beginning on the date immediately preceding the earlier to occur
of (1) the consummation of the applicable Change of Control and (2) the public announcement of such Change of Control and ending
on the date the Holder delivers the Change of Control Redemption Notice by (II) the Conversion
Price then in effect and (iii) the product of (y) the Change of Control Redemption
Premium multiplied by (z) the product of (A) the Conversion Amount being redeemed multiplied by (B) the quotient of (I) the aggregate
cash consideration and the aggregate cash value of any non-cash consideration per share of Common Stock to be paid to the holders
of the shares of Common Stock upon consummation of such Change of Control (any such non-cash consideration constituting publicly-traded
securities shall be valued at the highest of the Closing Sale Price of such securities as of the Trading Day immediately prior
to the consummation of such Change of Control, the Closing Sale Price of such securities on the Trading Day immediately following
the public announcement of such proposed Change of Control and the Closing Sale Price of such securities on the Trading Day immediately
prior to the public announcement of such proposed Change of Control) divided by (II) the Conversion Price then in effect (the “Change
of Control Redemption Price”). Redemptions required by this Section 5 shall be made in accordance with the provisions
of Section 11 and shall have priority to payments to stockholders in connection with such Change of Control. To the extent redemptions
required by this Section 5(b) are deemed or determined by a court of competent jurisdiction to be prepayments of this Note by the
Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section
5, but subject to Section 3(d), until the Change of Control Redemption Price (together with any Late Charges thereon) is paid in
full, the Conversion Amount submitted for redemption under this Section 5(b) (together with any Late Charges thereon) may be converted,
in whole or in part, by the Holder into Common Stock pursuant to Section 3. In the event of a partial redemption of this Note pursuant
hereto, the Principal amount redeemed shall be deducted from the Installment Amount(s) relating to the applicable Installment Date(s)
as set forth in the Change of Control Redemption Notice. In the event of the Company’s redemption of any portion of this
Note under this Section 5(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’
inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity
for the Holder. Accordingly, any redemption premium due under this Section 5(b) is intended by the parties to be, and shall be
deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a penalty.

6.            RIGHTS
UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

 

(a)          Purchase
Rights. In addition to any adjustments pursuant to Section 7 below, if at any time the Company grants, issues or sells any
Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders
of any class of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the
terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had
held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations
or restrictions on the convertibility of this Note) immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to
be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that the Holder’s right
to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not
be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result
of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such
time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage).

 

(b)          Other
Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental
Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect
to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision
to insure that the Holder will thereafter have the right to receive upon a conversion of this Note (i) in addition to the shares
of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with
respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate
Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares
of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of
Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled
to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares
of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to
the preceding sentence shall be in a form and substance satisfactory to the Holder. The provisions of this Section 6 shall apply
similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or
redemption of this Note.

7.            RIGHTS
UPON ISSUANCE OF OTHER SECURITIES.

 

(a)          Adjustment
of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Subscription Date the Company issues or
sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any shares of Common
Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account
of the Company, but excluding any Excluded Securities issued or sold or deemed to have been issued or sold) for a consideration
per share (the “New Issuance Price”) less than a price equal to the Conversion Price in effect immediately prior
to such issue or sale or deemed issuance or sale (such Conversion Price then in effect is referred to herein as the “Applicable
Price”) (the foregoing a “Dilutive Issuance”), then, immediately after such Dilutive Issuance, the
Conversion Price then in effect shall be reduced to an amount equal to the lesser of (x) the Conversion Price then in effect and
(y) the New Issuance Price. For all purposes of the foregoing (including, without limitation, determining the adjusted Conversion
Price and consideration per share under this Section 7(a)), the following shall be applicable:

 

(i)          Issuance
of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of
Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities
issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to
be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price
per share. For purposes of this Section 7(a)(i), the “lowest price per share for which one share of Common Stock is issuable
upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise
of any such Option” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received
or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of such Option, upon exercise
of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option and
(y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable upon the exercise of any
such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option,
minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the granting or sale of
such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise
of such Option plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such
Option (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the
actual issuance of such share of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the actual
issuance of such share of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

 

    	15

    	 

    

 

(ii)         Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per
share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the
time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 7(a)(ii),
the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof”
shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company
with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or
exchange of such Convertible Security and (y) the lowest conversion price set forth in such Convertible Security for which one
share of Common Stock is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all amounts paid or payable
to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the
value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security (or
any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance
of such share of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale
of such Convertible Securities is made upon exercise of any Options for which adjustment of the Conversion Price has been or is
to be made pursuant to other provisions of this Section 7(a), except as contemplated below, no further adjustment of the Conversion
Price shall be made by reason of such issue or sale.

 

(iii)        Change
in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration,
if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible
Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the
Conversion Price in effect at the time of such increase or decrease shall be adjusted to the Conversion Price which would have
been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price,
additional consideration or increased or decreased conversion rate (as the case may be) at the time initially granted, issued or
sold. For purposes of this Section 7(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the
Subscription Date are increased or decreased in the manner described in the immediately preceding sentence, then such Option or
Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed
to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 7(a) shall be made if such
adjustment would result in an increase of the Conversion Price then in effect.

 

    	16

    	 

    

 

(iv)         Calculation
of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the
issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary
Security”, and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary Securities”),
together comprising one integrated transaction, the consideration per share of Common Stock with respect to such Primary Security
shall be deemed to be equal to the difference of (x) the lowest price per share for which one share of Common Stock was issued
in such integrated transaction (or was deemed to be issued pursuant to Section 7(a)(i) or 7(a)(ii) above, as applicable) solely
with respect to such Primary Security, minus (y) with respect to such Secondary Securities, the sum of (I) the Black Scholes Consideration
Value of each such Option, if any, (II) the fair market value (as determined by the Holder) or the Black Scholes Consideration
Value, as applicable, of such Adjustment Right, if any, and (III) the fair market value (as determined by the Holder) of such Convertible
Security, if any, in each case, as determined on a per share basis in accordance with this Section 2(b)(iv). If any shares of Common
Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received
therefor (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not
for the purpose of the calculation of the Black Scholes Consideration Value) will be deemed to be the net amount of consideration
received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration
other than cash (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but
not for the purpose of the calculation of the Black Scholes Consideration Value), the amount of such consideration received by
the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities,
in which case the amount of consideration received by the Company for such securities will be the average VWAP of such security
for the five (5) Trading Day period immediately preceding the date of receipt. If any shares of Common Stock, Options or Convertible
Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the surviving
entity (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not for
the purpose of the calculation of the Black Scholes Consideration Value), the amount of consideration therefor will be deemed to
be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares
of Common Stock, Options or Convertible Securities (as the case may be). The fair value of any consideration other than cash or
publicly traded securities will be determined jointly by the Company and the Holder. If such parties are unable to reach agreement
within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”), the fair
value of such consideration will be determined within five (5) Trading Days after the tenth (10th) day following such
Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder. The determination of such
appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be
borne by the Company.

 

(v)          Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive
a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for
or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making
of such other distribution or the date of the granting of such right of subscription or purchase (as the case may be).

 

    	17

    	 

    

 

(b)          Adjustment
of Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision of Section 5 or Section
7(a), if the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, stock combination,
recapitalization or other similar transaction) one or more classes of its outstanding shares of Common Stock into a greater number
of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. Without limiting
any provision of Section 5 or Section 7(a), if the Company at any time on or after the Subscription Date combines (by
any stock split, stock dividend, stock combination, recapitalization or other similar transaction) one or more classes of its outstanding
shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will
be proportionately increased. Any adjustment pursuant to this Section 7(b) shall become effective immediately after the effective
date of such subdivision or combination. If any event requiring an adjustment under this Section 7(b) occurs during the period
that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted appropriately
to reflect such event.

 

(c)          Holder’s
Right of Alternative Conversion Price. Subject to Section 4(n) of the Securities Purchase Agreement, in addition to and not
in limitation of the other provisions of this Section 7, if the Company in any manner issues or sells or enters into any agreement
to issue or sell, any Common Stock, Options or Convertible Securities (any such securities, “Variable Price Securities”)
after the Subscription Date that are issuable pursuant to such agreement or convertible into or exchangeable or exercisable for
shares of Common Stock pursuant to such Options or Convertible Securities, as applicable, at a price which varies or may vary with
the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price, but exclusive of such
formulations reflecting customary anti-dilution provisions (such as share splits, share combinations, share dividends and similar
transactions) (each of the formulations for such variable price being herein referred to as, the “Variable Price”),
the Company shall provide written notice thereof via facsimile and overnight courier to the Holder on the date of such agreement
and/or the issuance of such Convertible Securities or Options, as applicable. Subject to Section 4(n) of the Securities Purchase
Agreement, from and after the date the Company enters into such agreement or issues any such Variable Price Securities, the Holder
shall have the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Conversion Price
upon conversion of this Note by designating in the Conversion Notice delivered upon any conversion of this Note that solely for
purposes of such conversion the Holder is relying on the Variable Price rather than the Conversion Price then in effect. The Holder’s
election to rely on a Variable Price for a particular conversion of this Note shall not obligate the Holder to rely on a Variable
Price for any future conversion of this Note.

 

(d)          Other
Events. In the event that the Company (or any Subsidiary) shall take any action to which the provisions hereof are not strictly
applicable, or, if applicable, would not operate to protect the Holder from dilution or if any event occurs of the type contemplated
by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting
of stock appreciation rights, phantom stock rights or other rights with equity features), then the Company’s board of directors
shall in good faith determine and implement an appropriate adjustment in the Conversion Price so as to protect the rights of the
Holder, provided that no such adjustment pursuant to this Section 7(d) will increase the Conversion Price as otherwise determined
pursuant to this Section 7, provided further that if the Holder does not accept such adjustments as appropriately protecting its
interests hereunder against such dilution, then the Company’s board of directors and the Holder shall agree, in good faith,
upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination
shall be final and binding and whose fees and expenses shall be borne by the Company.

 

    	18

    	 

    

 

(e)          Calculations.
All calculations under this Section 7 shall be made by rounding to the nearest cent or the nearest 1/100th of a
share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held
by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

 

8.            COMPANY
INSTALLMENT CONVERSION OR REDEMPTION.

 

(a)  General.
On each applicable Installment Date, the Company shall pay to the Holder of this Note the applicable Installment Amount due on
such date by converting such Installment Amount in accordance with this Section 8 (a “Company Conversion”);
provided further that the Company shall not be entitled to effect a Company Conversion with respect to any portion of such Installment
Amount and shall be required to pay the entire amount of such Installment Amount in cash (a “Company Redemption”)
if on the applicable Installment Notice Due Date or on the applicable Installment Date (as the case may be) there is an Equity
Conditions Failure, except that a Company Conversion may still occur on the applicable Installment Date in accordance with Section
8(b) with the written consent of the Holder. On the date which is the twenty-three (23rd) Trading Day prior to each
Installment Date (each, an “Installment Notice Due Date”), the Company shall deliver written notice (each, a
“Company Installment Notice” and the date all of the holders receive such notice is referred to as to the “Company
Installment Notice Date”), to each holder of Notes and such Company Installment Notice shall (i) either (A) confirm that
the applicable Installment Amount of such holder’s Note shall be converted in whole pursuant to a Company Conversion or (B)
(1) state that the Company is required to redeem, in accordance with the provisions of the Notes, in whole or in part, the applicable
Installment Amount pursuant to a Company Redemption and (2) specify the portion of the applicable Installment Amount which the
Company is required to redeem, pursuant to a Company Redemption (such amount to be redeemed in cash, the “Company Redemption
Amount”) and the portion of the applicable Installment Amount, if any, with respect to which the Company will, and is
permitted to, effect a Company Conversion (such amount of the applicable Installment Amount so specified to be so converted pursuant
to this Section 8 is referred to herein as the “Company Conversion Amount”), which amounts when added together,
must equal the entire applicable Installment Amount and (ii) if the applicable Installment Amount is to be paid, in whole or in
part, pursuant to a Company Conversion, certify that there is not then an Equity Conditions Failure as of the date of the Company
Installment Notice. Each Company Installment Notice shall be irrevocable and may not be revoked by the Company. If the Company
does not timely deliver a Company Installment Notice in accordance with this Section 8 with respect to a particular Installment
Date, then the Company shall be deemed to have delivered an irrevocable Company Installment Notice confirming a Company Conversion
of the entire Installment Amount payable on such Installment Date and shall be deemed to have certified that there is not then
an Equity Conditions Failure in connection with such Company Conversion. No later than two (2) Trading Days after delivery or deemed
delivery (as applicable) of the applicable Company Installment Notice setting forth a Company Conversion Amount, the Company shall
deliver to the Holder’s account with DTC such number of shares of Common Stock (the “Pre-Installment Conversion
Shares”) equal to the quotient of (x) such Company Conversion Amount divided by (y) the Pre-Installment Conversion Price,
and as to which the Holder shall be the owner thereof as of such time of delivery or deemed delivery (as the case may be) of such
Company Installment Notice. Except as expressly provided in this Section 8(a), the Company shall convert and/or redeem the applicable
Installment Amount of this Note pursuant to this Section 8 and the corresponding Installment Amounts of the Other Notes pursuant
to the corresponding provisions of the Other Notes in the same ratio of the applicable Installment Amount being converted and/or
redeemed hereunder. The applicable Company Conversion Amount (whether set forth in the applicable Company Installment Notice or
by operation of this Section 8) shall be converted in accordance with Section 8(b) and the applicable Company Redemption Amount
shall be redeemed in accordance with Section 8(c).

 

    	19

    	 

    

 

(b)  Mechanics
of Company Conversion. Subject to Section 3(d), if the Company delivers a Company Installment Notice or is deemed to have delivered
a Company Installment Notice certifying that such Installment Amount is being paid, in whole or in part, in a Company Conversion
in accordance with Section 8(a), then the remainder of this Section 8(b) shall apply. The applicable Company Conversion Amount,
if any, shall be converted on the applicable Installment Date at the applicable Company Conversion Price and the Company shall,
on such Installment Date, deliver to the Holder’s account with DTC such shares of Common Stock issued upon such conversion
(subject to the reduction contemplated by the immediately following sentence and, if applicable, the penultimate sentence of this
Section 8(b)), provided that the Equity Conditions are then satisfied (or waived in writing by the Holder) on such Installment
Date and a Company Conversion is not otherwise prohibited under any other provision of this Note. The number of shares of Common
Stock to be delivered upon such Company Conversion shall be reduced by the number of any Pre-Installment Conversion Shares delivered
in connection with such Installment Date. If an Event of Default occurs during any applicable Equity Conditions Measuring Period,
then, at the option of the Holder designated in writing to the Company, either (i) the Holder shall return to the Company all,
or any part, of such Pre-Installment Conversion Shares delivered in connection with the applicable Installment Date or (ii) the
Conversion Amount used to calculate the Event of Default Redemption Price shall be reduced by the product of (x) the Company Conversion
Amount applicable to such Installment Date (as adjusted downward proportionally with respect to any Pre-Installment Conversion
Shares returned to the Company pursuant to clause (i) above) multiplied by (y) the Conversion Share Ratio (as defined below). If
any of the Equity Conditions are not satisfied (or waived in writing by the Holder) on such Installment Date or a Company Conversion
is not otherwise permitted under any other provision of this Note, then, at the option of the Holder designated in writing to the
Company, the Holder may require the Company to do any one or more of the following: (i) the Company shall redeem all or any part
designated by the Holder of the unconverted Company Conversion Amount (such designated amount is referred to as the “Designated
Redemption Amount”) and the Company shall pay to the Holder within three (3) days of such Installment Date, by wire transfer
of immediately available funds, an amount in cash equal to 125% of such Designated Redemption Amount, and/or (ii) the Company Conversion
shall be null and void with respect to all or any part designated by the Holder of the unconverted Company Conversion Amount and
the Holder shall be entitled to all the rights of a holder of this Note with respect to such designated part of the Company Conversion
Amount; provided, however, the Conversion Price for such designated part of such unconverted Company Conversion Amount shall thereafter
be adjusted to equal the lesser of (A) the Company Conversion Price as in effect on the date on which the Holder voided the Company
Conversion and (B) the Company Conversion Price that would be in effect on the date on which the Holder delivers a Conversion Notice
relating thereto as if such date was an Installment Date. In addition, if any of the Equity Conditions are not satisfied (or waived
in writing by the Holder) on such Installment Date or a Company Conversion is not otherwise permitted under any other provision
of this Note, then, at the Holder’s option, either (I) the Holder shall return any Pre-Installment Conversion Shares delivered
in connection with the applicable Installment Date or (II) the applicable Designated Redemption Amount shall be reduced by the
product of (X) the Company Conversion Amount applicable to such Installment Date multiplied by (Y) the Conversion Share Ratio.
If the Company fails to redeem any Designated Redemption Amount by the third (3rd) day following the applicable Installment
Date by payment of such amount by such date, then the Holder shall have the rights set forth in Section 11(a) as if the Company
failed to pay the applicable Company Installment Redemption Price (as defined below) and all other rights under this Note (including,
without limitation, such failure constituting an Event of Default described in Section 4(a)(vi)). Notwithstanding anything to the
contrary in this Section 8(b), but subject to 3(d), until the Company delivers Common Stock representing the Company Conversion
Amount to the Holder, the Company Conversion Amount may be converted by the Holder into Common Stock pursuant to Section 3. In
the event that the Holder elects to convert the Company Conversion Amount prior to the applicable Installment Date as set forth
in the immediately preceding sentence, the Company Conversion Amount so converted shall be deducted from the Installment Amount(s)
relating to the applicable Installment Date(s) as set forth in the applicable Conversion Notice. If, with respect to an Installment
Date, the number of Pre-Installment Conversion Shares delivered to the Holder exceeds the number of Post-Installment Conversion
Shares with respect to such Installment Date, then the number of shares of Common Stock equal to such excess shall constitute a
credit against the number of shares of Common Stock to be issued to such Holder pursuant to Section 8(a) hereof, at the option
of the Holder, either (x) against any conversion of this Note pursuant to Section 3(c)(i) as selected by the Holder or (y) on the
Maturity Date, or, if earlier, the last Installment Date, reducing the number of shares of Common Stock required to be actually
issued by the Company to the Holder on such date by the amount of such excess on a share-for-share basis. The Company shall pay
any and all taxes that may be payable with respect to the issuance and delivery of any shares of Common Stock in any Company Conversion
hereunder.

(c)  Mechanics
of Company Redemption. If the Company is required to effect a Company Redemption, in whole or in part, in accordance with Section
8(a), then the Company Redemption Amount, if any, shall be redeemed by the Company in cash on the applicable Installment Date by
wire transfer to the Holder of immediately available funds in an amount equal to the applicable Company Redemption Amount (the
“Company Installment Redemption Price”). If the Company fails to redeem such Company Redemption Amount on such
Installment Date by payment of the Company Installment Redemption Price, then, at the option of the Holder designated in writing
to the Company (any such designation shall be a “Conversion Notice” for purposes of this Note), the Holder may
require the Company to convert all or any part of the Company Redemption Amount at the Company Conversion Price (determined as
of the date of such designation as if such date were an Installment Date). Conversions required by this Section 8(c) shall be made
in accordance with the provisions of Section 3(c). Notwithstanding anything to the contrary in this Section 8(c), but subject to
Section 3(d), until the Company Installment Redemption Price (together with any Late Charges thereon) is paid in full, the Company
Redemption Amount (together with any Late Charges thereon) may be converted, in whole or in part, by the Holder into Common Stock
pursuant to Section 3. In the event the Holder elects to convert all or any portion of the Company Redemption Amount prior to the
applicable Installment Date as set forth in the immediately preceding sentence, the Company Redemption Amount so converted shall
be deducted from the Installment Amounts relating to the applicable Installment Date(s) as set forth in the applicable Conversion
Notice. Redemptions required by this Section 8(c) shall be made in accordance with the provisions of Section 11.

 

(d)  Deferred
Installment Amount. Notwithstanding any provision of this Section 8(d) to the contrary, the Holder may, at its option and in
its sole discretion, deliver a written notice to the Company no later than the Trading Day immediately prior to the applicable
Installment Date electing to have the payment of all or any portion of an Installment Amount payable on such Installment Date deferred
(such amount deferred, the “Deferral Amount”) until any subsequent Installment Date
selected by the Holder, in its sole discretion, in which case, the Deferral Amount shall be added to, and become part of, such
subsequent Installment Amount and such Deferral Amount shall continue to accrue Interest hereunder. Any notice delivered by the
Holder pursuant to this Section 8(d) shall set forth (i) the Deferral Amount and (ii) the date that such Deferral Amount shall
now be payable. Notwithstanding anything herein to the contrary, with respect to any Installment Dates occurring during the period
commencing on the Effective Date (as defined in the Registration Rights Agreement) and ending on September 30, 2013, if any, if
the Company is not eligible to consummate a Company Conversion pursuant to this Section 8 with respect to such Installment Dates
due to an Equity Conditions Failure (and the Holder has not waived such Equity Conditions Failure), the applicable Deferral Amount
shall be deferred until any subsequent Installment Date selected in writing by the Holder, in its sole discretion, in which case,
the Deferral Amount shall be added to, and become part of, such subsequent Installment Amount (or, in absence of any such election
prior to the immediately subsequent Installment Date, such Deferral Amount shall be allocated pro rata, and become part of, such
remaining Installment Dates) and such Deferral Amount shall continue to accrue Interest hereunder.

 

    	21

    	 

    

 

(e)  Conversion
of Installment Amounts. Notwithstanding anything herein to the contrary, during the period commencing on an Installment Date
(a “Current Installment Date”) and ending on the Trading Day immediately prior to the next Installment Date
(each, an “Installment Period”), at the option of the Holder, at one or more times, the Holder may convert other
Installment Amounts (an “Installment Amount Conversion”), in whole or in part, at the Company Conversion Price
of such Current Installment Date in accordance with the conversion procedures set forth in Section 3 hereunder, mutatis mutandis.
Notwithstanding the foregoing, with respect to any given Installment Period, the Holder may not elect to effect any Installment
Amount Conversion during such Installment Period if either (x) in the aggregate, all the Installment Amount Conversions in such
Installment Period exceeds the sum of two (2) other Installment Amounts (or, if the Company has effected a Company Conversion with
respect to the entire Installment Amount of such Installment Date, one (1) other Installment Amount), (y) more than five (5) separate
Installment Amount Conversions have been consummated in such Installment Period or (z) the Holder has effected Installment Amount
Conversions in at least six (6) prior Installment Periods.

 

9.            NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation (as defined
in the Securities Purchase Agreement), Bylaws (as defined in the Securities Purchase Agreement) or through any reorganization,
transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and will at all times in good faith
carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this
Note. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of
Common Stock receivable upon conversion of this Note above the Conversion Price then in effect, (ii) shall take all such actions
as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares
of Common Stock upon the conversion of this Note, and (iii) shall, so long as any of the Notes are outstanding, take all action
necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting
the conversion of the Notes, the maximum number of shares of Common Stock as shall from time to time be necessary to effect the
conversion of the Notes then outstanding (without regard to any limitations on conversion).

 

    	22

    	 

    

 

10.          RESERVATION
OF AUTHORIZED SHARES.

 

(a)          Reservation.
The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares of Common Stock for each
of the Notes equal to 125% of the entire Conversion Rate with respect to the entire Conversion Amount of each such Note as of the
Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action necessary to reserve and keep
available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 125%
of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes then
outstanding, provided that at no time shall the number of shares of Common Stock so reserved be less than the number of shares
required to be reserved by the previous sentence (without regard to any limitations on conversions) (the “Required Reserve
Amount”). The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the
number of shares so reserved shall be allocated pro rata among the holders of the Notes based on the original principal amount
of the Notes held by each holder on the Closing Date or increase in the number of reserved shares (as the case may be) (the “Authorized
Share Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each
transferee shall be allocated a pro rata portion of such holder’s Authorization Share Allocation. Any shares of Common Stock
reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata
based on the principal amount of the Notes then held by such holders.

 

(b)          Insufficient
Authorized Shares. If, notwithstanding Section 10(a), and not in limitation thereof, at any time while any of the Notes remain
outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation
to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required Reserve
Amount (an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase
the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve
Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after
the date of the occurrence of an Authorized Share Failure, but in no event later than ninety (90) days after the occurrence of
such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number
of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy
statement and shall use its best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common
Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. In the event that the
Company is prohibited from issuing shares of Common Stock upon any conversion due to the failure by the Company to have sufficient
shares of Common Stock available out of the authorized but unissued shares of Common Stock (such unavailable number of shares of
Common Stock, the “Authorization Failure Shares”), in lieu of delivering such Authorization Failure Shares to
the Holder, the Company shall pay cash in exchange for the redemption of such portion of the Conversion Amount convertible into
such Authorized Failure Shares at a price equal to the sum of (i) the product of (x) such number of Authorization Failure Shares
and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date the Holder
delivers the applicable Conversion Notice with respect to such Authorization Failure Shares to the Company and ending on the date
of such issuance and payment under this Section 10(a) and (ii) to the extent the Holder purchases (in an open market transaction
or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Authorization Failure Shares, any brokerage
commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith. Nothing contained in Section
10(a) or this Section 10(b) shall limit any obligations of the Company under any provision of the Securities Purchase Agreement.

 

    	23

    	 

    

 

11.          REDEMPTIONS.

 

(a)          Mechanics.
The Company shall deliver the applicable Event of Default Redemption Price to the Holder in cash within five (5) Business Days
after the Company’s receipt of the Holder’s Event of Default Redemption Notice. If the Holder has submitted a Change
of Control Redemption Notice in accordance with Section 5(b), the Company shall deliver the applicable Change of Control Redemption
Price to the Holder in cash concurrently with the consummation of such Fundamental Transaction if such notice is received prior
to the consummation of such Fundamental Transaction and within five (5) Business Days after the Company’s receipt of such
notice otherwise. The Company shall deliver the applicable Company Installment Redemption Price to the Holder in cash on the applicable
Installment Date. Notwithstanding anything herein to the contrary, in connection with any redemption hereunder at a time the Holder
is entitled to receive a cash payment under any of the other Transaction Documents, at the option of the Holder delivered in writing
to the Company, the applicable Redemption Price hereunder shall be increased by the amount of such cash payment owed to the Holder
under such other Transaction Document and, upon payment in full or conversion in accordance herewith, shall satisfy the Company’s
payment obligation under such other Transaction Document. In the event of a redemption of less than all of the Conversion Amount
of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section
17(d)) representing the outstanding Principal which has not been redeemed. In the event that the Company does not pay the applicable
Redemption Price to the Holder within the time period required, at any time thereafter and until the Company pays such unpaid Redemption
Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder
all or any portion of this Note representing the Conversion Amount that was submitted for redemption and for which the applicable
Redemption Price (together with any Late Charges thereon) has not been paid. Upon the Company’s receipt of such notice, (x)
the applicable Redemption Notice shall be null and void with respect to such Conversion Amount, (y) the Company shall immediately
return this Note, or issue a new Note (in accordance with Section 17(d)), to the Holder, and in each case the principal amount
of this Note or such new Note (as the case may be) shall be increased by an amount equal to the difference between (1) the applicable
Event of Default Redemption Price, Change of Control Redemption Price or Company Installment Redemption Price (as the case may
be, and as adjusted pursuant to this Section 11, if applicable) minus (2) the Principal portion of the Conversion Amount submitted
for redemption and (z) the Conversion Price of this Note or such new Notes (as the case may be) shall be automatically adjusted
with respect to each conversion effected thereafter by the Holder to the lowest of (A) the Conversion Price as in effect on the
date on which the applicable Redemption Notice is voided, (B) 85% of the lowest Closing Bid Price of the Common Stock during the
period beginning on and including the date on which the applicable Redemption Notice is delivered to the Company and ending on
and including the date on which the applicable Redemption Notice is voided and (C) 85% of the VWAP of the Common Stock for the
five (5) Trading Day period immediately preceding the Conversion Date of the applicable conversion. The Holder’s delivery
of a notice voiding a Redemption Notice and exercise of its rights following such notice shall not affect the Company’s obligations
to make any payments of Late Charges which have accrued prior to the date of such notice with respect to the Conversion Amount
subject to such notice.

 

    	24

    	 

    

 

(b)          Redemption
by Other Holders. Upon the Company’s receipt of notice from any of the holders of the Other Notes for redemption or repayment
as a result of an event or occurrence substantially similar to the events or occurrences described in Section 4(b) or Section 5(b)
(each, an “Other Redemption Notice”), the Company shall immediately, but no later than one (1) Business Day
of its receipt thereof, forward to the Holder by facsimile a copy of such notice. If the Company receives a Redemption Notice and
one or more Other Redemption Notices, during the seven (7) Business Day period beginning on and including the date which is three
(3) Business Days prior to the Company’s receipt of the Holder’s applicable Redemption Notice and ending on and including
the date which is three (3) Business Days after the Company’s receipt of the Holder’s applicable Redemption Notice
and the Company is unable to redeem all principal, interest and other amounts designated in such Redemption Notice and such Other
Redemption Notices received during such seven (7) Business Day period, then the Company shall redeem a pro rata amount from each
holder of the Notes (including the Holder) based on the principal amount of the Notes submitted for redemption pursuant to such
Redemption Notice and such Other Redemption Notices received by the Company during such seven (7) Business Day period.

 

12.          VOTING
RIGHTS. The Holder shall have no voting rights as the holder of this Note, except as required by law (including, without limitation,
the Delaware Business Corporation Act) and as expressly provided in this Note.

 

13.          COVENANTS.
Until all of the Notes have been converted, redeemed or otherwise satisfied in accordance with their terms:

 

(a)          Rank.
All payments due under this Note (a) shall rank pari passu with all Other Notes and (b) shall be senior to all other Indebtedness
of the Company and its Subsidiaries.

 

(b)          Incurrence
of Indebtedness. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly,
incur or guarantee, assume or suffer to exist any Indebtedness other than (i) the Indebtedness evidenced by this Note and the Other
Notes and (ii) other Permitted Indebtedness.

 

(c)          Existence
of Liens. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, allow
or suffer to exist any mortgage, lien, pledge, charge, security interest or other encumbrance upon or in any property or assets
(including accounts and contract rights) owned by the Company or any of its Subsidiaries (collectively, “Liens”)
other than Permitted Liens.

 

    	25

    	 

    

 

(d)          Restricted
Payments. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, redeem,
defease, repurchase, repay or make any payments in respect of, by the payment of cash or cash equivalents (in whole or in part,
whether by way of open market purchases, tender offers, private transactions or otherwise), all or any portion of any Indebtedness,
whether by way of payment in respect of principal of (or premium, if any) or interest on, such Indebtedness if at the time such
payment is due or is otherwise made or, after giving effect to such payment, (i) an event constituting an Event of Default has
occurred and is continuing or (ii) an event that with the passage of time and without being cured would constitute an Event of
Default has occurred and is continuing.

 

(e)          Restriction
on Redemption and Cash Dividends. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly
or indirectly, redeem, repurchase or declare or pay any cash dividend or distribution on any of its capital stock.

 

(a)          Restriction
on Transfer of Assets. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly,
sell, lease, license, assign, transfer, spin-off, split-off, close, convey or otherwise dispose of any assets or rights of the
Company or any Subsidiary owned or hereafter acquired whether in a single transaction or a series of related transactions, other
than (i) sales, leases, licenses, assignments, transfers, conveyances and other dispositions of such assets or rights by the Company
and its Subsidiaries in the ordinary course of business and (ii) sales of inventory and product in the ordinary course of business.

 

(f)           Maturity
of Indebtedness. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly,
permit any Indebtedness of the Company or any of the Subsidiaries to mature or accelerate prior to the Maturity Date.

 

(g)          Change
in Nature of Business. The Company shall not, and the Company shall cause each of its Subsidiaries to not, directly or
indirectly, engage in any material line of business substantially different from those lines of business conducted by the Company
and each of its Subsidiaries on the Issuance Date or any business substantially related or incidental thereto. The Company shall
not, and the Company shall cause each of its Subsidiaries to not, directly or indirectly, modify its or their corporate structure
or purpose.

 

(h)          Preservation
of Existence, Etc. The Company shall maintain and preserve, and cause each of its Subsidiaries to maintain and preserve, its
existence, rights and privileges, and become or remain, and cause each of its Subsidiaries to become or remain, duly qualified
and in good standing in each jurisdiction in which the character of the properties owned or leased by it or in which the transaction
of its business makes such qualification necessary.

 

(i)           Maintenance
of Properties, Etc. The Company shall maintain and preserve, and cause each of its Subsidiaries to maintain and preserve, all
of its properties which are necessary or useful in the proper conduct of its business in good working order and condition, ordinary
wear and tear excepted, and comply, and cause each of its Subsidiaries to comply, at all times with the provisions of all leases
to which it is a party as lessee or under which it occupies property, so as to prevent any loss or forfeiture thereof or thereunder.

 

    	26

    	 

    

 

(j)           Maintenance
of Intellectual Property. The Company will, and will cause each of its Subsidiaries to, take all action necessary or advisable
to maintain all of the Intellectual Property Rights of the Company and/or any of its Subsidiaries that are necessary or material
to the conduct of its business in full force and effect.

 

(k)          Maintenance
of Insurance. The Company shall maintain, and cause each of its Subsidiaries to maintain, insurance with responsible and reputable
insurance companies or associations (including, without limitation, comprehensive general liability, hazard, rent and business
interruption insurance) with respect to its properties (including all real properties leased or owned by it) and business, in such
amounts and covering such risks as is required by any governmental authority having jurisdiction with respect thereto or as is
carried generally in accordance with sound business practice by companies in similar businesses similarly situated.

 

(l)           Transactions
with Affiliates. The Company shall not, nor shall it permit any of its Subsidiaries to, enter into, renew, extend or be a party
to, any transaction or series of related transactions (including, without limitation, the purchase, sale, lease, transfer or exchange
of property or assets of any kind or the rendering of services of any kind) with any affiliate, except in the ordinary course of
business in a manner and to an extent consistent with past practice and necessary or desirable for the prudent operation of its
business, for fair consideration and on terms no less favorable to it or its Subsidiaries than would be obtainable in a comparable
arm’s length transaction with a Person that is not an affiliate thereof.

 

(m)          Restricted
Issuances. The Company shall not, directly or indirectly, without the prior written consent of the holders of a majority in
aggregate principal amount of the Notes then outstanding, (i) issue any Notes (other than as contemplated by the Securities Purchase
Agreement and the Notes) or (ii) issue any other securities that would cause a breach or default under the Notes or the Warrants.

 

(n)          Controlled
Accounts; Control Account Release; Collateral.

 

(i)          The
Company shall establish and maintain a bank account for each holder of Notes (collectively, the “Master Restricted Accounts”,
with the Master Restricted Account attributable the Holder as defined in Section 29(z) below) at a bank or a financial institution
satisfactory to such holder of Notes (each, as applicable, a “Controlled Account Bank”), which Master Restricted
Account applicable to a holder of Notes shall be subject to deposit account control agreement in form and substance reasonably
acceptable to such holder of Notes (the “Controlled Account Agreement”). Each Controlled Account Agreement shall
provide, among other things, that (A) the applicable Controlled Account Bank will comply with any and all instructions originated
by such holder of Notes directing the disposition of the funds in the Controlled Accounts without further consent by the Company
or any such Subsidiaries, (B) such Controlled Account Bank waives, subordinates or agrees not to exercise any rights of setoff
or recoupment or any other claim against the applicable Master Restricted Account other than for payment of its service fees and
other charges directly related to the administration of such Master Restricted Account and for returned checks or other items of
payment, and (C) such Controlled Account Bank shall not comply with any instructions, directions or orders of any form with respect
to such Master Restricted Account other than instructions, directions or orders originated by the applicable Holder of Notes. On
the Issuance Date, the Company shall have directed the initial Buyers to deposit an aggregate of $6 million of the Purchase Price
(as defined in the Securities Purchase Agreement) into the Master Restricted Account.

 

    	27

    	 

    

 

(ii)         Upon
the occurrence of any Control Account Release Event, the Holder shall, as soon as commercially practicable, but in no event later
than two (2) Trading Days thereafter, cause a cash amount equal to such applicable Restricted Principal to be released from the
Master Restricted Account attributable to the Holder and deposited into an bank account specified in writing by the Company on
or prior to such date (each a “Control Account Release”); provided, that if the Company fails to select a bank
account in a writing delivered to the Holder on or prior to such second Trading Day, the Holder shall effect such Control Account
Release as soon as commercially practicable after receipt of such bank account election from the Company.

 

(iii)        The
Company hereby grants and pledges to the Holder a continuing security interest in any cash or other assets, from time to time,
in the Master Restricted Account attributable to the Restricted Principal hereunder (the “Collateral”) to secure
prompt repayment of any and all amounts outstanding hereunder from time to time and to secure prompt performance by the Company
of each of its covenants and duties under the Transaction Documents (as defined in the Securities Purchase). Such security interest
constitutes a valid, first priority security interest in the presently existing Collateral, and will constitute a valid, first
priority security interest in later-acquired Collateral. Notwithstanding any filings undertaken related to Holder’s rights
under the Delaware Uniform Commercial Code, the Holder’s Lien (as defined in the Notes) on the Collateral shall remain in
effect for so long as any Restricted Principal remains outstanding. Notwithstanding the foregoing, upon any Control Account Release,
but solely with respect to such portion of the Restricted Principal hereunder subject to such Control Account Release (each, a
“Control Account Release Amount”), the Holder hereby automatically releases any lien hereunder on such Control
Account Release Amount.

 

(iv)        Notwithstanding
anything herein to the contrary, at the option of the Holder, the Holder may satisfy all, or any part, of any redemption or other
cash payment obligation of the Company hereunder (each, a “Cash Payment Obligation”) from the Collateral in
the Master Restricted Account, including, without limitation, in connection with any Event of Default, Change of Control, Company
Installment Redemption or payment due at the Maturity Date.  In connection with any Cash Payment Obligation hereunder, the
Company hereby irrevocably consents to the Holder’s delivery of an instruction letter to the Controlled Account Bank to release
Collateral from the Master Restricted Account in an amount not to exceed such Cash Payment Obligation to the Holder.  Notwithstanding
the foregoing, in the absence of any such election by the Holder, the Company shall remain obligated to pay such Cash Payment Obligation
to the Holder without regard to any Collateral in the Master Restricted Account. Upon the occurrence of any event which could reasonably
be expected to result in a Cash Payment Obligation, the Holder may, at the Holder’s option, withdraw any Collateral in the
Master Restricted Account; provided that (x) such withdrawn amount shall not exceed such amount which the Holder reasonably believes
would be necessary to satisfy such Cash Payment Obligation, and (y) such withdrawal shall not constitute the delivery of a Redemption
Notice hereunder or payment hereunder unless the Holder specifies in writing to the Company that the Holder has applied such Collateral
in satisfaction of such Cash Payment Obligation.

 

    	28

    	 

    

 

(v)         If
the Controlled Account Bank breaches any covenant or other term or condition of any Account Control Agreement or otherwise fails
to promptly comply with the instructions of the Holder in connection with the Collateral, the Holder may, at its option, withdraw
the Collateral from the Controlled Account Bank and hold such Collateral until such time as (x) the Company and the Holder have
agreed upon a replacement Controlled Account Bank and (y) a Controlled Account Agreement with respect to such Collateral and a
new account shall have been duly executed by the Company, the Holder and the replacement Controlled Account Bank. Notwithstanding
anything herein to the contrary, if the Company or any of its Subsidiaries receives any of the Collateral in breach of any Account
Control Agreement (or receives notice from any holder of Notes that an amount was wired to the Company from a Master Restricted
Account attributable to such holder of Notes without the proper authorization of such holder of Notes), the Company shall promptly
cause such amounts to be returned to such applicable Master Restricted Account.

 

14.          PARTICIPATION.
In addition to any adjustments pursuant to Section 7, the Holder, as the holder of this Note, shall be entitled to receive such
dividends paid and distributions made to the holders of Common Stock to the same extent as if the Holder had converted this Note
into Common Stock (without regard to any limitations on conversion herein or elsewhere) and had held such shares of Common Stock
on the record date for such dividends and distributions. Payments under the preceding sentence shall be made concurrently with
the dividend or distribution to the holders of Common Stock (provided, however, to the extent that the Holder’s right to
participate in any such dividend or distribution would result in the Holder exceeding the Maximum Percentage, then the Holder shall
not be entitled to participate in such dividend or distribution to such extent (or the beneficial ownership of any such shares
of Common Stock as a result of such dividend or distribution to such extent) and such dividend or distribution to such extent shall
be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder
exceeding the Maximum Percentage).

 

15.          AMENDING
THE TERMS OF THIS NOTE. The prior written consent of the Holder shall be required for any change or amendment to this Note.

 

16.          TRANSFER.
This Note and any shares of Common Stock issued upon conversion of this Note may be offered, sold, assigned or transferred by the
Holder without the consent of the Company, subject only to the provisions of Section 2(g) of the Securities Purchase Agreement.

 

    	29

    	 

    

 

17.          REISSUANCE

and in addition to all other remedies available under this Note and any of the other Transaction Documents at law or in equity

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

1.          EXERCISE
OF WARRANT.

 

(a)          Mechanics
of Exercise. Subject to the terms and conditions hereof (including, without limitation, the limitations set forth in Section 1(f)),
this Warrant may be exercised by the Holder on any day on or after the Initial Exercisability Date, in whole or in part, by delivery
(whether via facsimile or otherwise) of a written notice, in the form attached hereto as Exhibit A (the “Exercise
Notice”), of the Holder’s election to exercise this Warrant. Within one (1) Trading Day following an exercise of
this Warrant as aforesaid, the Holder shall deliver payment to the Company of an amount equal to the Exercise Price in effect on
the date of such exercise multiplied by the number of Warrant Shares as to which this Warrant was so exercised (the “Aggregate
Exercise Price”) in cash or via wire transfer of immediately available funds if the Holder did not notify the Company
in such Exercise Notice that such exercise was made pursuant to a Cashless Exercise (as defined in Section 1(d)). The Holder
shall not be required to deliver the original of this Warrant in order to effect an exercise hereunder. Execution and delivery
of an Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the original
of this Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. Execution
and delivery of an Exercise Notice for all of the then-remaining Warrant Shares shall have the same effect as cancellation of the
original of this Warrant after delivery of the Warrant Shares in accordance with the terms hereof. On or before the second (2nd)
Trading Day following the date on which the Company has received an Exercise Notice, the Company shall transmit by facsimile an
acknowledgment of confirmation of receipt of such Exercise Notice, in the form attached hereto as Exhibit B,
to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the third (3rd)
Trading Day following the date on which the Company has received such Exercise Notice, the Company shall (X) provided that the
Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program,
upon the request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder is entitled pursuant
to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian
system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver
to the Holder or, at the Holder’s instruction pursuant to the Exercise Notice, the Holder’s agent or designee, in each
case, sent by reputable overnight courier to the address as specified in the applicable Exercise Notice, a certificate, registered
in the Company’s share register in the name of the Holder or its designee (as indicated in the applicable Exercise Notice),
for the number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. Upon delivery of an Exercise
Notice, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect
to which this Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account
or the date of delivery of the certificates evidencing such Warrant Shares (as the case may be). If this Warrant is submitted in
connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted
for exercise is greater than the number of Warrant Shares being acquired upon an exercise, then, at the request of the Holder,
the Company shall as soon as practicable and in no event later than five (5) Business Days after any exercise and at its own expense,
issue and deliver to the Holder (or its designee) a new Warrant (in accordance with Section 7(d)) representing the right to
purchase the number of Warrant Shares purchasable immediately prior to such exercise under this Warrant, less the number of Warrant
Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise
of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number.
The Company shall pay any and all taxes and fees which may be payable with respect to the issuance and delivery of Warrant Shares
upon exercise of this Warrant. Notwithstanding the foregoing, except in the case where an exercise of this Warrant is validly made
pursuant to a Cashless Exercise (as defined in Section 1(d)), the Company’s failure to deliver Warrant Shares to the
Holder on or prior to the second (2nd) Trading Day after the Company’s receipt of the Aggregate Exercise Price shall not
be deemed to be a breach of this Warrant.

 

    	2

    	 

    

  

(b)          Exercise
Price. For purposes of this Warrant, “Exercise Price” means $0.302, subject to adjustment as provided herein.

 

(c)          Company’s
Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for no reason, to issue to the Holder within
the later of (i) three (3) Trading Days after receipt of the applicable Exercise Notice and (ii) two (2) Trading Days after the
Company’s receipt of the Aggregate Exercise Price (or valid notice of a Cashless Exercise) (such later date, the “Share
Delivery Deadline”), a certificate for the number of shares of Common Stock to which the Holder is entitled and register
such shares of Common Stock on the Company’s share register or to credit the Holder’s balance account with DTC for
such number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise of this Warrant (as the
case may be) (a “Delivery Failure”), then, in addition to all other remedies available to the Holder, the Company
shall pay in cash to the Holder on each day after such Share Delivery Deadline that the issuance of such shares of Common Stock
is not timely effected an amount equal to 1% per month of the product of (A) the aggregate number of shares of Common Stock not
issued to the Holder on a timely basis and to which the Holder is entitled and (B) the Closing Sale Price of the Common Stock on
the Trading Day immediately preceding the last possible date on which the Company could have issued such shares of Common Stock
to the Holder without violating Section 1(a). In addition to the foregoing, if on or prior to the Share Delivery Deadline,
the Company shall fail to issue and deliver a certificate to the Holder and register such shares of Common Stock on the Company’s
share register or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder
is entitled upon the Holder’s exercise hereunder (as the case may be), and if on or after such Share Delivery Deadline the
Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the
Holder of all or any portion of the number of shares of Common Stock, or a sale of a number of shares of Common Stock equal to
all or any portion of the number of shares of Common Stock, issuable upon such exercise that the Holder so anticipated receiving
from the Company, then, in addition to all other remedies available to the Holder, the Company shall, within three (3) Business
Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal
to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares
of Common Stock so purchased (including, without limitation, by any other Person in respect, or on behalf, of the Holder) (the
“Buy-In Price”), at which point the Company’s obligation to so issue and deliver such certificate or credit
the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s
exercise hereunder (as the case may be) (and to issue such shares of Common Stock) shall terminate, or (ii) promptly honor its
obligation to so issue and deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit
the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s
exercise hereunder (as the case may be) and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price
over the product of (A) such number of shares of Common Stock multiplied by (B) the lowest Closing Sale Price of the Common Stock
on any Trading Day during the period commencing on the date of the applicable Exercise Notice and ending on the date of such issuance
and payment under this clause (ii).

 

    	3

    	 

    

  

(d)          Cashless
Exercise. Notwithstanding anything contained herein to the contrary (other than Section 1(f) below), if at any time of
exercise hereof a Registration Statement (as defined in the Registration Rights Agreement) is not effective (or the prospectus
contained therein is not available for use on a continuous basis) for the resale by the Holder of the Warrant Shares being exercised
pursuant to the applicable Exercise Notice at market prices from time to time, then the Holder may, in its sole discretion, exercise
this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon
such exercise in payment of the Aggregate Exercise Price, elect instead to receive upon such exercise the “Net Number”
of shares of Common Stock determined according to the following formula (a “Cashless Exercise”):

 

Net Number = (A x B) - (A x C)

D

 

For purposes of the foregoing formula:

 

A =  the total number of shares
with respect to which this Warrant is then being exercised.

 

B =  the quotient of (x)
the sum of the VWAP of the Common Stock of each of the ten (10) Trading Days ending at the close of business on the Principal
Market immediately prior to the time of exercise as set forth in the applicable Exercise Notice, divided by (y) ten (10).

 

C =  the Exercise Price then
in effect for the applicable Warrant Shares at the time of such exercise.

 

D =  the VWAP of the Common
Stock at the close of business on the Principal Market on the date of the delivery of the applicable Exercise Notice.

 

(e)          Disputes.
In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant Shares
to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the number of Warrant Shares that are
not disputed and resolve such dispute in accordance with Section 13.

 

    	4

    	 

    

 

(f)          Limitations
on Exercises. Notwithstanding anything to the contrary contained in this Warrant, this Warrant shall not be exercisable by
the Holder hereof to the extent (but only to the extent) that after giving effect to such exercise the Holder (together with any
of its affiliates) would beneficially own in excess of  4.99% (the “Maximum Percentage”) of the Common Stock.
To the extent the above limitation applies, the determination of whether this Warrant shall be exercisable (vis-à-vis other
convertible, exercisable or exchangeable securities owned by the Holder or any of its affiliates) and of which such securities
shall be convertible, exercisable or exchangeable (as the case may be, as among all such securities owned by the Holder) shall,
subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company for conversion,
exercise or exchange (as the case may be). No prior inability to exercise this Warrant pursuant to this paragraph shall have any
effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability.
For the purposes of this paragraph, beneficial ownership and all determinations and calculations (including, without limitation,
with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the 1934 Act
(as defined in the Securities Purchase Agreement) and the rules and regulations promulgated thereunder. The provisions of this
paragraph shall be implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct this
paragraph (or any portion hereof) which may be defective or inconsistent with the intended Maximum Percentage beneficial ownership
limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage
limitation. The limitations contained in this paragraph shall apply to a successor Holder of this Warrant. The holders of Common
Stock shall be third party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of
holders of a majority of its Common Stock. For any reason at any time, upon the written or oral request of the Holder, the Company
shall within two (2) Business Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding,
including by virtue of any prior conversion or exercise of convertible or exercisable securities into Common Stock, including,
without limitation, pursuant to this Warrant or securities issued pursuant to the Securities Purchase Agreement. At any time the
Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified in a written
notice by the Holder to the Company (subject to the Company’s consent to any such increase, not to be unreasonably withheld);
provided that (i) any such increase will not be effective until the 61st day after such notice is delivered to the Company, and
(ii) any such increase or decrease will apply only to the Holder sending such notice and not to any other holder of SPA Warrants.

 

    	5

    	 

    

 

(g)          Insufficient
Authorized Shares. The Company shall at all times keep reserved for issuance under this Warrant a number of shares of Common
Stock at least equal to 100% of the maximum number of shares of Common Stock as shall be necessary to satisfy the Company’s
obligation to issue shares of Common Stock hereunder (without regard to any limitation otherwise contained herein with respect
to the number of shares of Common Stock that may be acquirable upon exercise of this Warrant). If, notwithstanding the foregoing,
and not in limitation thereof, at any time while any of the SPA Warrants remain outstanding the Company does not have a sufficient
number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of the
SPA Warrants at least a number of shares of Common Stock (the “Required Reserve Amount”) equal to the number
of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of the SPA Warrants then outstanding
(an “Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the
Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve
Amount for all the SPA Warrants then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable
after the date of the occurrence of an Authorized Share Failure, but in no event later than ninety (90) days after the occurrence
of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number
of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy
statement and shall use its reasonable best efforts to solicit its stockholders’ approval of such increase in authorized
shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. In
the event that the Company is prohibited from issuing shares of Common Stock upon an exercise of this Warrant due to the failure
by the Company to have sufficient shares of Common Stock available out of the authorized but unissued shares of Common Stock (such
unavailable number of shares of Common Stock, the “Authorization Failure Shares”), in lieu of delivering such
Authorization Failure Shares to the Holder, the Company shall pay cash in exchange for the cancellation of such portion of this
Warrant exercisable into such Authorized Failure Shares at a price equal to the sum of (i) the product of (x) such number of Authorization
Failure Shares and (y) the greatest Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the
date the Holder delivers the applicable Exercise Notice with respect to such Authorization Failure Shares to the Company and ending
on the date of such issuance and payment under this Section 1(g) and (ii) to the extent the Holder purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of Authorization Failure Shares,
any brokerage commissions and other out-of-pocket expenses, if any, of the Holder incurred in connection therewith.

 

2.          ADJUSTMENT
OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and number of Warrant Shares issuable upon
exercise of this Warrant are subject to adjustment from time to time as set forth in this Section 2.

 

(a)          Stock
Dividends and Splits. Without limiting any provision of Section 2(b) or Section 4, if the Company, at any time on
or after the date of the Securities Purchase Agreement, (i) pays a stock dividend on one or more classes of its then outstanding
shares of Common Stock or otherwise makes a distribution on any class of capital stock that is payable in shares of Common Stock,
(ii) subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its then outstanding
shares of Common Stock into a larger number of shares or (iii) combines (by combination, reverse stock split or otherwise) one
or more classes of its then outstanding shares of Common Stock into a smaller number of shares, then in each such case the Exercise
Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock 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 clause (i) of this paragraph shall become effective immediately after the record date for
the determination of stockholders entitled to receive such dividend or distribution, and any adjustment pursuant to clause (ii)
or (iii) of this paragraph shall become effective immediately after the effective date of such subdivision or combination. If any
event requiring an adjustment under this paragraph occurs during the period that an Exercise Price is calculated hereunder, then
the calculation of such Exercise Price shall be adjusted appropriately to reflect such event.

 

    	6

    	 

    

 

(b)          Adjustment
Upon Issuance of Shares of Common Stock. If and whenever on or after the date of the Securities Purchase Agreement, the Company
issues or sells, or in accordance with this Section 2 is deemed to have issued or sold, any shares of Common Stock (including
the issuance or sale of shares of Common Stock owned or held by or for the account of the Company, but excluding any Excluded Securities
issued or sold or deemed to have been issued or sold) for a consideration per share (the “New Issuance Price”)
less than a price equal to the Exercise Price in effect immediately prior to such issue or sale or deemed issuance or sale (such
Exercise Price then in effect is referred to as the “Applicable Price”) (the foregoing a “Dilutive
Issuance”), then immediately after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to an amount
equal to the New Issuance Price. For all purposes of the foregoing (including, without limitation, determining the adjusted Exercise
Price and consideration per share under this Section 2(b)), the following shall be applicable:

 

(i)          Issuance
of Options. If the Company in any manner grants or sells any Options and the lowest price per share for which one share of
Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities
issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to
be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price
per share. For purposes of this Section 2(b)(i), the “lowest price per share for which one share of Common Stock is
issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable
upon exercise of any such Option” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if
any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of such Option,
upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such
Option and (y) the lowest exercise price set forth in such Option for which one share of Common Stock is issuable upon the exercise
of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option
minus (2) the sum of all amounts paid or payable to the holder of such Option (or any other Person) upon the granting or sale of
such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise
of such Option plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such
Option (or any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the
actual issuance of such shares of Common Stock or of such Convertible Securities upon the exercise of such Options or upon the
actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

 

    	7

    	 

    

 

(ii)         Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per
share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the
time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 2(b)(ii),
the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof”
shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company
with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or
exchange of such Convertible Security and (y) the lowest conversion price set forth in such Convertible Security for which one
share of Common Stock is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all amounts paid or payable
to the holder of such Convertible Security (or any other Person) upon the issuance or sale of such Convertible Security plus the
value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security (or
any other Person). Except as contemplated below, no further adjustment of the Exercise Price shall be made upon the actual issuance
of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale
of such Convertible Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made
pursuant to other provisions of this Section 2(b), except as contemplated below, no further adjustment of the Exercise Price
shall be made by reason of such issue or sale.

 

(iii)        Change
in Option Price or Rate of Conversion. If the purchase or exercise price provided for in any Options, the additional consideration,
if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible
Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the
Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have been
in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional
consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For
purposes of this Section 2(b)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date
of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding sentence, then such
Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall
be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 2(b) shall
be made if such adjustment would result in an increase of the Exercise Price then in effect.

 

    	8

    	 

    

 

(iv)        Calculation
of Consideration Received. If any Option and/or Convertible Security and/or Adjustment Right is issued in connection with the
issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary
Security”, and such Option and/or Convertible Security and/or Adjustment Right, the “Secondary Securities”),
together comprising one integrated transaction, the consideration per share of Common Stock with respect to such Primary Security
shall be deemed to be equal to the difference of (x) the lowest price per share for which one share of Common Stock was issued
in such integrated transaction (or was deemed to be issued pursuant to Section 2(b)(i) or 2(b)(ii) above, as applicable) solely
with respect to such Primary Security, minus (y) with respect to such Secondary Securities, the sum of (I) the Black Scholes Consideration
Value of each such Option, if any, (II) the fair market value (as determined by the Holder) or the Black Scholes Consideration
Value, as applicable, of such Adjustment Right, if any, and (III) the fair market value (as determined by the Holder) of such Convertible
Security, if any, in each case, as determined on a per share basis in accordance with this Section 2(b)(iv). If any shares of Common
Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received
therefor (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but not
for the purpose of the calculation of the Black Scholes Consideration Value) will be deemed to be the net amount of consideration
received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration
other than cash (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible Security, but
not for the purpose of the calculation of the Black Scholes Consideration Value), the amount of such consideration received by
the Company will be the fair value of such consideration, except where such consideration consists of publicly traded securities,
in which case the amount of consideration received by the Company for such securities will be the arithmetic average of the VWAPs
of such security for each of the five (5) Trading Days immediately preceding the date of receipt. If any shares of Common Stock,
Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the
Company is the surviving entity (for the purpose of determining the consideration paid for such Common Stock, Option or Convertible
Security, but not for the purpose of the calculation of the Black Scholes Consideration Value), the amount of consideration therefor
will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable
to such shares of Common Stock, Options or Convertible Securities, as the case may be. The fair value of any consideration other
than cash or publicly traded securities will be determined jointly by the Company and the Holder. If such parties are unable to
reach agreement within ten (10) days after the occurrence of an event requiring valuation (the “Valuation Event”),
the fair value of such consideration will be determined within five (5) Trading Days after the tenth (10th) day following
such Valuation Event by an independent, reputable appraiser jointly selected by the Company and the Holder. The determination of
such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall
be borne by the Company.

 

(v)         Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to
receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to
subscribe for or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be
the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend
or the making of such other distribution or the date of the granting of such right of subscription or purchase (as the case may
be).

 

(c)          Number
of Warrant Shares. Simultaneously with any adjustment to the Exercise Price pursuant to paragraphs (a), (b), (d) or (e) Fundamental
Transaction of this Section 2, the number of Warrant Shares that may be purchased upon exercise of this Warrant shall be increased
or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the adjusted number
of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment (without regard
to any limitations on exercise contained herein).

 

    	9

    	 

    

  

(d)          Holder's
Right of Alternative Exercise Price Following Issuance of Certain Options or Convertible Securities. In addition to and not
in limitation of the other provisions of this Section 2, if the Company in any manner issues or sells any Options or Convertible
Securities (any such securities, "Variable Price Securities") after the Subscription Date that are convertible
into or exchangeable or exercisable for shares of Common Stock at a price which varies or may vary with the market price of the
Common Shares, including by way of one or more reset(s) to a fixed price, but exclusive of such formulations reflecting customary
anti-dilution provisions (such as share splits, share combinations, share dividends and similar transactions) (each of the formulations
for such variable price being herein referred to as, the "Variable Price"), the Company shall provide written
notice thereof via facsimile and overnight courier to the Holder on the date of issuance of such Convertible Securities or Options.
From and after the date the Company issues any such Convertible Securities or Options with a Variable Price, the Holder shall have
the right, but not the obligation, in its sole discretion to substitute the Variable Price for the Exercise Price upon exercise
of this Warrant by designating in the Exercise Notice delivered upon any exercise of this Warrant that solely for purposes of such
exercise the Holder is relying on the Variable Price rather than the Exercise Price then in effect. The Holder's election to rely
on a Variable Price for a particular exercise of this Warrant shall not obligate the Holder to rely on a Variable Price for any
future exercises of this Warrant.

 

(e)          Stock
Combination Event Adjustment. If at any time and from time to time on or after the Issuance Date there occurs any stock
split, stock dividend, stock combination recapitalization or other similar transaction involving the Common Stock (each, a “Stock
Combination Event”) and the product of (i) the quotient determined by dividing (x) the Exercise Price in effect immediately
prior to the Stock Combination Event by (y) the quotient determined by dividing (A) the sum of the VWAP of the Common Stock on
each day of the fifteen (15) Trading Day period immediately prior to the Stock Combination Event, divided by (B) fifteen (15);
and (ii) the quotient determined by dividing (x) the sum of the VWAP of the Common Stock on each day of the fifteen (15) Trading
Day period immediately following the date of such Stock Combination Event, divided by (y) fifteen (15) (each, an “Event
Market Price”) is less than the Exercise Price then in effect (after giving effect to the adjustment in clause (b) above),
then on the sixteenth (16th) Trading Day immediately following such Stock Combination Event, the Exercise Price then in effect
on such sixteenth (16th) Trading Day (after giving effect to the adjustment in clause (b) above) shall be reduced (but in no event
increased) to the Event Market Price. For the avoidance of doubt, if the adjustment in the immediately preceding sentence would
otherwise result in an increase in the Exercise Price hereunder, no adjustment shall be made.

 

(f)          Other
Events. In the event that the Company (or any Subsidiary (as defined in the Securities Purchase Agreement)) shall take any
action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect the Holder from
dilution or if any event occurs of the type contemplated by the provisions of this Section 2 but not expressly provided for
by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights
with equity features), then the Company’s board of directors shall in good faith determine and implement an appropriate adjustment
in the Exercise Price and the number of Warrant Shares (if applicable) so as to protect the rights of the Holder, provided that
no such adjustment pursuant to this Section 2(e) will increase the Exercise Price or decrease the number of Warrant Shares
as otherwise determined pursuant to this Section 2, provided further that if the Holder does not accept such adjustments as
appropriately protecting its interests hereunder against such dilution, then the Company’s board of directors and the Holder
shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments,
whose determination shall be final and binding and whose fees and expenses shall be borne by the Company.

 

    	10

    	 

    

  

(g)          Calculations.
All calculations under this Section 2 shall be made by rounding to the nearest cent or the nearest 1/100th of a
share, as applicable. The number of shares of Common Stock outstanding at any given time shall not include shares owned or held
by or for the account of the Company, and the disposition of any such shares shall be considered an issue or sale of Common Stock.

 

3.          RIGHTS
UPON DISTRIBUTION OF ASSETS. In addition to any adjustments pursuant to Section 2 above, if the Company shall
declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common
Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities,
property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other
similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such
case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated
therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without
regard to any limitations on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date
on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares
of Common Stock are to be determined for the participation in such Distribution (provided, however, to the extent that the Holder’s
right to participate in any such Distributions would result in the Holder exceeding the Maximum Percentage, then the Holder shall
not be entitled to participate in such Distribution to such extent (or the beneficial ownership of any such shares of Common Stock
as a result of such Distribution to such extent) and such Distribution to such extent shall be held in abeyance for the benefit
of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage).

 

4.          PURCHASE
RIGHTS; FUNDAMENTAL TRANSACTIONS.

 

(a)          Purchase
Rights. In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells
any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to
any limitations on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date on which
a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which
the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided,
however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding
the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial
ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent
shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding
the Maximum Percentage).

 

    	11

    	 

    

  

(b)          Fundamental
Transactions. The Company shall not enter into or be party to a Fundamental Transaction unless (i)  the Successor Entity
assumes in writing all of the obligations of the Company under this Warrant and the other Transaction Documents (as defined in
the Securities Purchase Agreement) in accordance with the provisions of this Section 4(b) pursuant to written agreements in
form and substance satisfactory to the Holder and approved by the Holder prior to such Fundamental Transaction, including agreements
to deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant, including, without limitation, which is exercisable for a corresponding number of
shares of capital stock equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without
regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which
applies the exercise 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 adjustments to the
number of shares of capital stock and such exercise price being for the purpose of protecting the economic value of this Warrant
immediately prior to the consummation of such Fundamental Transaction) and (ii) the Successor Entity (including its Parent
Entity) is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market. Upon the
consummation of each Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after
the date of the applicable Fundamental Transaction, the provisions of this Warrant 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 Warrant and the other Transaction Documents with the same effect
as if such Successor Entity had been named as the Company herein. Upon consummation of each Fundamental Transaction, the Successor
Entity shall deliver to the Holder confirmation that there shall be issued upon exercise of this Warrant at any time after the
consummation of the applicable Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets
or other property (except such items still issuable under Sections 3 and 4(a) above, which shall continue to be receivable
thereafter)) issuable upon the exercise of this Warrant prior to the applicable Fundamental Transaction, such shares of publicly
traded common stock (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been
entitled to receive upon the happening of the applicable Fundamental Transaction had this Warrant been exercised immediately prior
to the applicable Fundamental Transaction (without regard to any limitations on the exercise of this Warrant), as adjusted in accordance
with the provisions of this Warrant. Notwithstanding the foregoing, and without limiting Section 1(f) hereof, the Holder may elect,
at its sole option, by delivery of written notice to the Company to waive this Section 4(b) to permit the Fundamental Transaction
without the assumption of this Warrant. In addition to and not in substitution for any other rights hereunder, prior to the consummation
of each Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other
assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the Company shall make
appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any
time after the consummation of the applicable Fundamental Transaction but prior to the Expiration Date, in lieu of the shares of
the Common Stock (or other securities, cash, assets or other property (except such items still issuable under Sections 3 and
4(a) above, which shall continue to be receivable thereafter)) issuable upon the exercise of the Warrant prior to such Fundamental
Transaction, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase
or subscription rights) which the Holder would have been entitled to receive upon the happening of the applicable Fundamental Transaction
had this Warrant been exercised immediately prior to the applicable Fundamental Transaction (without regard to any limitations
on the exercise of this Warrant). Provision made pursuant to the preceding sentence shall be in a form and substance reasonably
satisfactory to the Holder.

Notes remain outstanding), the Company or the Successor Entity (as the case may be) shall purchase this
Warrant from the Holder on the date of such request by paying to the Holder cash in an amount equal to the Event of Default
Black Scholes Value.

 

(d)          Application.
The provisions of this Section 4 shall apply similarly and equally to successive Fundamental Transactions and Corporate Events
and shall be applied as if this Warrant (and any such subsequent warrants) were fully exercisable and without regard to any limitations
on the exercise of this Warrant (provided that the Holder shall continue to be entitled to the benefit of the Maximum Percentage,
applied however with respect to shares of capital stock registered under the 1934 Act and thereafter receivable upon exercise of

time to time be necessary to effect the exercise of the SPA Warrants then outstanding (without regard to any limitations on exercise).

 

6.          WARRANT
HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely in its capacity
as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the
Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in its capacity
as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent
to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance
or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the
Holder of the Warrant Shares which it is then entitled to receive upon the due exercise of this Warrant. In addition, nothing
contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise
of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors
of the Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices and
other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders.

10.         SEVERABILITY.
If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court
of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended
to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision
shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to
express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature,
invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal
obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The
parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid
provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

 

11.         GOVERNING
LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning
the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State
of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York
or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York.
The Company 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 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 brought in an
inconvenient forum or that the venue of such suit, action or proceeding is improper. Nothing contained herein shall be deemed
to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate
to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to collect
on the Company’s obligations to the Holder or to enforce a judgment or other court ruling in favor of the Holder. THE
COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY
DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY.

 

12.         CONSTRUCTION;
HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not be construed
against any Person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part
of, or affect the interpretation of, this Warrant. Terms used in this Warrant but defined in the other Transaction Documents shall
have the meanings ascribed to such terms on the Closing Date (as defined in the Securities Purchase Agreement) in such other Transaction
Documents unless otherwise consented to in writing by the Holder.

13.         DISPUTE
RESOLUTION. In the case of a dispute as to the determination of the Exercise Price, the Closing Sale Price, the Bid
Price or fair market value or the arithmetic calculation of the number of Warrant Shares (as the case may be), the Company or
the Holder (as the case may be) shall submit the disputed determinations or arithmetic calculations (as the case may be) via facsimile
(i) within two (2) Business Days after receipt of the applicable notice giving rise to such dispute to the Company or the Holder
(as the case may be) or (ii) if no notice gave rise to such dispute, at any time after the Holder learned of the circumstances
giving rise to such dispute (including, without limitation, as to whether any issuance or sale or deemed issuance or sale was
an issuance or sale or deemed issuance or sale of Excluded Securities). If the Holder and the Company are unable to agree upon
such determination or calculation (as the case may be) of the Exercise Price, the Closing Sale Price, the Bid Price or fair market
value or the number of Warrant Shares (as the case may be) within three (3) Business Days of such disputed determination or arithmetic
calculation being submitted to the Company or the Holder (as the case may be), then the Company shall, within two (2) Business
Days submit via facsimile (a) the disputed determination of the Exercise Price, the Closing Sale Price, the Bid Price or fair
market value (as the case may be) to an independent, reputable investment bank selected by the Holder that is reasonably acceptable
to the Company or (b) the disputed arithmetic calculation of the number of Warrant Shares to an independent, outside accountant
selected by the Holder that is reasonably acceptable to the Company. The Company shall cause at its expense the investment bank
or the accountant (as the case may be) to perform the determinations or calculations (as the case may be) and notify the Company
and the Holder of the results no later than ten (10) Business Days from the time it receives such disputed determinations or calculations
(as the case may be). Such investment bank’s or accountant’s determination or calculation (as the case may be) shall
be binding upon all parties absent demonstrable error.

 

14.         REMEDIES,
CHARACTERIZATION, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be
cumulative and in addition to all other remedies available under this Warrant and 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 right of
the Holder to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Warrant.
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, exercises 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 of this Warrant shall be entitled, in
addition to all other available remedies, to an injunction restraining any 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 Warrant (including, without limitation, compliance with Section 2 hereof). The issuance of shares and certificates for
shares as contemplated hereby upon the exercise of this Warrant shall be made without charge to the Holder or such shares for
any issuance tax or other costs in respect thereof, provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than the Holder or
its agent on its behalf.
