Note by check mailed to the address of the Holder of this Note entitled to such payment as set forth in the books of the Company
(or, if such Holder provides the Company, at least five (5) days before the date such amount is due, with written notice of an
account of such Holder within the United States, by wire transfer of immediately available funds to such account).

 

(B)             
Company’s Election to Pay Amortization Payments or Stated Interest in Cash or Common Stock. At least ten (10) Trading
Days (but no more than twenty (20) Trading Days) prior to an Amortization Date or Interest Payment Date, as applicable, the Company,
if it desires to elect to pay an Amortization Payment due on such Amortization Date or payment of Stated Interest due on such Interest
Payment Date in shares of Common Stock, shall deliver to the Holder a written notice of such election (a “Stock Payment
Notice”) (and such election shall be irrevocable as to such Amortization Date or Interest Payment Date, as applicable).
Failure to timely deliver such written notice to the Holder shall be deemed an election by the Company to pay the Amortization
Payment or payment of Stated Interest on such Amortization Date or Interest Payment Date, as applicable, in cash. With respect
to any Amortization Date or Interest Payment Date for which the Company has elected to make an Amortization Payment or payment
of Stated Interest in shares of Common Stock in accordance with this Section 5(B), the Company shall issue to the Holder,
in lieu of payment of such Amortization Payment or payment of Stated Interest in cash, a number of validly issued, fully paid and
Freely Tradable shares of Common Stock equal to the quotient (rounded up to the closest whole number) obtained by dividing such
Amortization Payment (or lesser amount elected by Holder and notified to the Company in accordance with this Note) by the Amortization
Stock Payment Price for the Stock Payment Date applicable to such Amortization Payment (such quotient, the “Amortization
Share Amount”) or by dividing such payment of Stated Interest by the Stated Interest Stock Payment Price for such payment
of Stated Interest (such quotient, the “Stated Interest Share Amount”), as applicable. In the event that the
number of shares of Common Stock issued to the Holder on such date is reduced as a result of the Floor Price, the Company shall
concurrently with the issuance of such shares also pay to the Holder an amount, in cash, equal to the product of (i) the number
of shares by which the Amortization Share Amount or Stated Interest Amount, as applicable, was reduced as a result of the Floor
Price, multiplied by (ii) the Amortization Stock Payment Price or Stated Interest Stock Payment Price, as applicable. Notwithstanding
anything herein to the contrary, the Company will not have the right to, and will not, make any Amortization Payment in shares
of Common Stock if the Equity Conditions are not satisfied for each VWAP Trading Day occurring between the date of the Stock Payment
Notice and the applicable Amortization Date, unless such failure of the Equity Conditions to be so satisfied is waived in writing
by the Holder, which waiver may be granted or withheld by the Holder in its sole discretion. To the extent that the Company’s
election to pay an Amortization Payment or a payment of Stated Interest in shares of Common Stock would cause the Beneficial Ownership
Limit pursuant to Section 8(J)(i) to be exceeded, the Company will deliver shares of Common Stock up to the Beneficial Ownership
Limit, and the excess amount of such Amortization Payment or Stock Payment, as applicable, shall be deferred to such future Amortization
Date or Stock Payment Date as Holder may elect in its sole discretion (or, if Holder shall not so elect prior to the next Amortization
Date or Stock Payment Date, the next Amortization Date or Stock Payment Date, as applicable.

(C)             
Stock Payment Date Election. If the Company elects to pay any Amortization Payment in shares of Common Stock, the Holder

on one or more Scheduled Trading Days (each, a “Stock Payment Date”) during the period beginning on, and including,
the applicable Amortization Date and ending on, and including, the Scheduled Trading Day immediately before the subsequent Amortization
Date (the “Amortization Share Payment Period”). The Holder must provide notice to the Company of its election
of any Stock Payment Date and the portion of the Amortization Payment and corresponding Amortization Share Amount it is electing
to receive on each such Stock Payment Date no later than 4:30 p.m. New York Time on such Stock Payment Date; provided, that
the Holder may make more than one election to receive portions of the Amortization Payment and corresponding Amortization Share
Amounts on any Stock Payment Date; and provided further, that the Amortization Share Amount in any such notice will be updated
following the close of trading on the applicable Stock Payment Date in order to reflect the final Amortization Stock Payment Price
applicable to such Stock Payment Date. Any portion of the Amortization Payment not paid in shares of Common Stock because the Holder
did not elect to receive shares for such full Amortization Payment on Stock Payment Dates during the applicable Amortization Share
Payment Period will be automatically deferred to the next Amortization Date.

 

(D)            
Event of Default/Equity Triggering Event Additional Shares. In the event of issuance of any Event of Default/Equity Triggering
Event Additional Shares, to the extent that the amount of such shares was reduced as a result of the Floor Price, then concurrently
with the issuance of such shares, the Company shall also pay to the Holder an amount, in cash, equal to the product of (i) the
number of shares by which such amount was reduced as a result of the Floor Price, multiplied by (ii) the Event of Default/Equity
Triggering Event Conversion Price.

 

(E)             
Delivery. Any shares of Common Stock to be delivered pursuant to this Section 5 will be delivered by the Company to the
Holder on or before the second (2nd) Business Day following the applicable Stock Payment Date or Interest Payment Date, as applicable.

 

(F)             
Delay of Payment when Payment Date is Not a Business Day. If the due date for a payment on this Note as provided in this
Note is not a Business Day, then, notwithstanding anything to the contrary in this Note, such payment may be made on the immediately
following Business Day and no interest will accrue on such payment as a result of the related delay.

Application and Replenishment of Pre-Delivery Shares. Notwithstanding anything to the contrary in this Note, at any time the Company
elects or is obligated to issue shares of Common Stock to the Holder pursuant to the terms of this Note, including with respect
to any conversion of this Note or pursuant to Section 5(B) or Section 6(F), the Holder may elect, upon written notice
to the Company, given no less than two (2) Trading Days prior to the date upon which the Company would otherwise be obligated to
deliver such shares to Holder, to apply Pre-Delivery Shares, in whole or in part, as applicable, against the shares of Common Stock
otherwise deliverable with respect thereto and, in each case, such application of Pre-Delivery Shares shall reduce the aggregate
number of shares of Common Stock otherwise required to be delivered to the Holder pursuant to the terms of this Note on a share-by-share
basis and such shares so applied shall no longer constitute Pre-Delivery Shares; provided, however, that no later
than the Amortization Date following any application of Pre-Delivery Shares in accordance with this Section 5(G)(ii), the
Company shall deliver to the Holder a number of validly issued, fully paid and nonassessable Freely Tradable shares of Common Stock,
free from all preemptive or similar rights or Liens with respect to the issue thereof, equal to the number of Pre-Delivery Shares
applied to satisfy any such election or obligation to issue shares of Common Stock under this Section 5(G)(ii), which such
Freely Tradable shares of Common Stock shall be treated as “Pre-Delivery Shares” for all purposes hereunder; and provided,
further, that any shares delivered pursuant to Section 5(G)(i) or this Section 5(G)(ii) shall count against
the share issuance limitation set forth in Section 8(J)(ii).

 

(iii)           
[Reserved]

Delivery of Pre-Delivery Shares by the Holder. Within ten (10) Business Days following redemption or repayment of this Note in

proportionate adjustments for events of the type set forth in Section 8(F)(i)(1)) of the Company’s Common Stock to
the Company, free from all preemptive or similar rights or Liens with respect to the delivery thereof; provided, that, to
the extent the Company fails to deliver any fully paid and nonassessable Freely Tradable shares of Common Stock to the Holder as
required under Section 5(G)(i) or Section 5(G)(ii), the number of shares of the Company’s Common Stock to be
delivered under this Section 5(G)(iv) shall be reduced by the number of such shares of Common Stock the Company failed to
deliver. For the avoidance of doubt, this Section 5(G)(iv) shall not apply to the transactions contemplated by the Exchange
Agreement.

and will be in an amount equal to the amount of consideration Holder would have received in connection with such Fundamental Change
had Holder redeemed the Note in exchange for shares of Common Stock immediately prior to the completion of such Fundamental Change.

in effect as of the Trading Day immediately preceding the related Redemption Date; (y) the Principal Amount of this Note to be
so redeemed divided by $1,000; and (z) the Redemption Stock Price for such redemption. [NTD: to be proportional amount of
$10,000,000 based on total amount of Notes issued.]

		Article	8.                                
Conversion.

 

(A)            
Right to Convert.

 

(i)                
Generally. Subject to the provisions of this Section 8, the Holder may, at its option, convert this Note, including
any portion constituting an Amortization Payment, into Conversion Consideration.

 

(ii)             
Conversions in Part. Subject to the terms of this Section 8, this Note may be converted in part, but only in an Authorized
Denomination. Provisions of this Section 8 applying to the conversion of this Note in whole will equally apply to conversions
of any permitted portion of this Note.

 

(B)             
When this Note May Be Converted.

 

(i)                
Generally. The Holder may convert this Note at any time until the Close of Business on the second (2nd) Scheduled Trading
Day immediately before the Maturity Date; provided that, with respect to the conversion of any Amortization Payment, the
Holder must provide notice of such conversion no later than the Close of Business on the second (2nd) Scheduled Trading Day immediately
preceding the applicable Amortization Date, and any such conversion will not reduce the amount of future Amortization Payments.

 

(ii)             
Limitations and Closed Periods. Notwithstanding anything to the contrary in this Section 8, (x) if this Note (or
any portion of this Note) is to be redeemed pursuant to Section 7(A), then in no event may this Note (or such portion) be
converted after the Close of Business on the second (2nd) Scheduled Trading Day immediately before the related Redemption
Date; and (y) if this Note (or any portion of this Note) is to be repurchased upon a Repurchase Upon Fundamental Change, then in
no event may this Note (or such portion) be converted after the Close of Business on the second (2nd) Scheduled Trading
Day immediately before the related Fundamental Change Repurchase Date.

 

(C)             
Conversion Procedures.

 

(i)                
Generally. To convert this Note, the Holder must (1) complete, manually sign and deliver to the Company the conversion notice
attached to this Note or a facsimile or portable document format (.pdf) version of such conversion notice (at which time such conversion
will become irrevocable); and (2) pay any amounts due pursuant to Section 8(C)(iii). For the avoidance of doubt, the conversion
notice may be delivered by e-mail in accordance with Section 14. If the Company fails to deliver, by the related Conversion
Settlement Date, any shares of Common Stock forming part of the Conversion Consideration of the conversion of this Note, the Holder,
by notice to the Company, may rescind all or any portion of the corresponding conversion notice at any time until such Defaulted
Shares are delivered.

 

    -20-

     

    

(ii)             
Holder of Record of Conversion Shares. The person in whose name any shares of Common Stock is issuable upon conversion of
this Note will be deemed to become the holder of record of such shares as of the Close of Business on the Conversion Date for such
conversion, conferring, as of such time, upon such person, without limitation, all voting and other rights appurtenant to such
shares.

 

(iii)           
Taxes and Duties. If the Holder converts a Note, the Company will pay any documentary, stamp or similar issue or transfer
tax or duty due on the issue of any shares of Common Stock upon such conversion; provided, however, that if any tax
or duty is due because such Holder requested such shares to be issued in a name other than that of such Holder, then such Holder
will pay such tax or duty and, until having received a sum sufficient to pay such tax or duty, the Company may refuse to deliver
any such shares to be issued in a name other than that of such Holder.

 

(D)            
Settlement upon Conversion.

 

(i)                
Generally. The consideration (the “Conversion Consideration”) due in respect of each $1,000 Principal
Amount of this Note including any portion constituting an Amortization Payment to be converted will consist of the following:

 

(1)              
subject to Section 8(D)(ii), a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion
Date for such conversion; and

 

(2)              
cash in an amount equal to the aggregate accrued and unpaid interest on this Note to, but excluding, the Conversion Settlement
Date for such conversion.

 

(ii)             
Fractional Shares. The total number of shares of Common Stock due in respect of any conversion of this Note, including any
portion constituting an Amortization Payment, will be determined on the basis of the total Principal Amount of this Note to be
converted with the same Conversion Date; provided, however, that if such number of shares of Common Stock is not
a whole number, then such number will be rounded up to the nearest whole number.

 

(iii)           
Delivery of the Conversion Consideration. The Company will pay or deliver, as applicable, the Conversion Consideration due
upon the conversion of this Note, including any portion constituting an Amortization Payment, to the Holder on or before the second
(2nd) Business Day (or, if earlier, the standard settlement period for the primary Eligible Exchange on which the Common Stock
is traded) immediately after the Conversion Date for such conversion (the “Conversion Settlement Date”).

 

(iv)            
Effect of Conversion. If this Note is converted, then, from and after the date the Conversion Consideration therefor is
issued or delivered in settlement of such conversion, this Note will cease to be outstanding and interest will cease to accrue
on this Note.

 

    -21-

     

    

(v)              
Conversion Settlement Defaults. If (x) the Company fails to deliver, by the related Conversion Settlement Date, any shares
of Common Stock (the “Defaulted Shares”) forming part of the Conversion Consideration of the conversion of this
Note, including any portion constituting an Amortization Payment; and (y) the Holder (whether directly or indirectly, including
by any broker acting on the Holder’s behalf or acting with respect to such Defaulted Shares) purchases any shares of Common
Stock (whether in the open market or otherwise) to cover any such Defaulted Shares (whether to satisfy any settlement obligations
with respect thereto of the Holder or otherwise), then, without limiting the Holder’s right to pursue any other remedy available
to it (whether hereunder, under applicable law or otherwise), the Holder will have the right, exercisable by notice to the Company,
to cause the Company to either:

 

(1)              
pay, on or before the second (2nd) Business Day after the date such notice is delivered, cash to the Holder in an amount equal
to the aggregate purchase price (including any brokerage commissions and other out-of-pocket costs) incurred to purchase such shares
(such aggregate purchase price, the “Covering Price”); or

 

(2)              
promptly deliver, to the Holder, such Defaulted Shares in accordance with this Note, together with cash in an amount equal to the
excess, if any, of the Covering Price over the product of (x) the number of such Defaulted Shares; and (y) the Daily VWAP per share
of Common Stock on the Conversion Date relating to such conversion.

 

To exercise such right, the Holder must deliver notice
of such exercise to the Company, specifying whether the Holder has elected clause (1) or (2) above to apply. If the
Holder has elected clause (1) to apply, then the Company’s obligation to deliver the Defaulted Shares in accordance
with this Note will be deemed to have been satisfied and discharged to the extent the Company has paid the Covering Price in accordance
with clause (1).

 

(E)             
Reserve and Status of Common Stock Issued upon Conversion.

 

(i)                
Stock Reserve. At all times when this Note is outstanding, the Company will reserve, out of its authorized but unissued
and unreserved shares of Common Stock, a number of shares of Common Stock equal to three hundred percent (300%) of that which is
sufficient to permit the conversion of this Note.

 

(ii)             
Status of Conversion Shares; Listing. Each share of Common Stock delivered upon conversion of this Note will be a newly
issued or treasury share and will be duly and validly issued, fully paid, non-assessable, free from preemptive rights and free
of any lien or adverse claim (except to the extent of any lien or adverse claim created by the action or inaction of the Holder
or the Person to whom such share will be delivered). If the Common Stock is then listed on any securities exchange, or quoted on
any inter-dealer quotation system, then the Company will cause each share of Common Stock issued upon conversion of this Note,
when delivered upon such conversion, to be admitted for listing on such exchange or quotation on such system.

 

(iii)           
Transferability of Conversion Shares. Any shares of Common Stock issued upon conversion of this Note will be issued in the
form of book-entries at the facilities of DTC, identified therein by an “unrestricted” CUSIP number.

 

    -22-

     

    

(F)             
Adjustments to the Conversion Rate.

 

(i)                
Events Requiring an Adjustment to the Conversion Rate. The Conversion Rate will be adjusted from time to time as follows:

 

(1)              
Stock Dividends, Splits and Combinations. If the Company issues solely shares of Common Stock as a dividend or distribution
on all or substantially all shares of the Common Stock, or if the Company effects a stock split or a stock combination of the Common
Stock (in each case excluding an issuance solely pursuant to a Common Stock Change Event, as to which Section 8(I) will
apply), then the Conversion Rate will be adjusted based on the following formula:

 

 

where:

 

CR0=the Conversion
Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution, or immediately
before the Open of Business on the effective date of such stock split or stock combination, as applicable;

 

CR1=the Conversion
Rate in effect immediately after the Open of Business on such Ex-Dividend Date or the Open of Business on such effective date,
as applicable;

 

OS0=the number
of shares of Common Stock outstanding immediately before the Open of Business on such Ex-Dividend Date or effective date, as applicable,
without giving effect to such dividend, distribution, stock split or stock combination; and

 

OS1=the number
of shares of Common Stock outstanding immediately after giving effect to such dividend, distribution, stock split or stock combination.

 

If any dividend, distribution, stock split or stock combination
of the type described in this Section 8(F)(i)(1) is declared or announced, but not so paid or made, then the Conversion
Rate will be readjusted, effective as of the date the Board of Directors determines not to pay such dividend or distribution or
to effect such stock split or stock combination, to the Conversion Rate that would then be in effect had such dividend, distribution,
stock split or stock combination not been declared or announced.

 

    -23-

     

    

(2)              
Rights, Options and Warrants. If the Company distributes, to all or substantially all holders of Common Stock, rights, options
or warrants (other than rights issued or otherwise distributed pursuant to a stockholder rights plan, as to which the provisions
set forth in Sections 8(F)(i)(3)(a) and Section 8(F)(v) will apply) entitling such holders, for a period of not more
than sixty (60) calendar days after the record date of such distribution, to subscribe for or purchase shares of Common Stock at
a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive
Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced, then the Conversion
Rate will be increased based on the following formula:

 

 

where:

 

CR0=the Conversion
Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;

 

CR1=the Conversion
Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

 

		OS	=the number of shares of Common Stock outstanding immediately before the Open of Business on
such Ex-Dividend Date;

 

		X	=the total number of shares of Common Stock issuable pursuant to such rights, options or warrants;
and

 

		Y	=a number of shares of Common Stock obtained by dividing (x) the aggregate price payable to
exercise such rights, options or warrants by (y) the average of the Last Reported Sale Prices per share of Common Stock for the
ten (10) consecutive Trading Days ending on, and including, the Trading Day immediately before the date such distribution is announced.

 

To the extent that shares of Common Stock are not delivered
after the expiration of such rights, options or warrants (including as a result of such rights, options or warrants not being exercised),
the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the increase to the Conversion Rate
for such distribution been made on the basis of delivery of only the number of shares of Common Stock actually delivered upon exercise
of such rights, option or warrants. To the extent such rights, options or warrants are not so distributed, the Conversion Rate
will be readjusted to the Conversion Rate that would then be in effect had the Ex-Dividend Date for the distribution of such rights,
options or warrants not occurred.

 

    -24-

     

    

For purposes of this Section 8(F)(i)(2), in determining
whether any rights, options or warrants entitle holders of Common Stock to subscribe for or purchase shares of Common Stock at
a price per share that is less than the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive
Trading Days ending on, and including, the Trading Day immediately before the date the distribution of such rights, options or
warrants is announced, and in determining the aggregate price payable to exercise such rights, options or warrants, there will
be taken into account any consideration the Company receives for such rights, options or warrants and any amount payable on exercise
thereof, with the value of such consideration, if not cash, to be determined by the Board of Directors in good faith.

 

(3)              
Spin-Offs and Other Distributed Property.

 

(a)              
Distributions Other than Spin-Offs. If the Company distributes shares of its Capital Stock, evidences of its indebtedness
or other assets or property of the Company, or rights, options or warrants to acquire Capital Stock of the Company or other securities,
to all or substantially all holders of the Common Stock, excluding:

 

(v)       dividends,
distributions, rights, options or warrants for which an adjustment to the Conversion Rate is required pursuant to Section 8(F)(i)(1)
or Section 8(F)(i)(2);

 

(w)       dividends
or distributions paid exclusively in cash for which an adjustment to the Conversion Rate is required pursuant to Section 8(F)(i)(4);

 

(x)       rights
issued or otherwise distributed pursuant to a stockholder rights plan, except to the extent provided in Section 8(F)(v);

 

(y)       Spin-Offs
for which an adjustment to the Conversion Rate is required pursuant to Section 8(F)(i)(3)(b); and

 

(z)       a
distribution solely pursuant to a Common Stock Change Event, as to which Section 8(I) will apply,

 

then the Conversion Rate will be increased based on the
following formula:

 

 

where:

 

CR0=the Conversion
Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such distribution;

 

    -25-

     

    

CR1=the Conversion
Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

 

		SP	=the average of the Last Reported Sale Prices per share of Common Stock for the ten (10) consecutive
Trading Days ending on, and including, the Trading Day immediately before such Ex-Dividend Date; and

 

		FMV	=the fair market value (as determined by the Board of Directors in good faith), as of such
Ex-Dividend Date, of the shares of Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants distributed
per share of Common Stock pursuant to such distribution;

 

provided, however, that if FMV is
equal to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate, the Holder will receive,
for each $1,000 Principal Amount of this Note held by this Holder on the record date for such distribution, at the same time and
on the same terms as holders of Common Stock, the amount and kind of shares of Capital Stock, evidences of indebtedness, assets,
property, rights, options or warrants that such Holder would have received if such Holder had owned, on such record date, a number
of shares of Common Stock equal to the Conversion Rate in effect on such record date.

 

To the extent such distribution is not so paid or made,
the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the
basis of only the distribution, if any, actually made or paid.

 

(b)              
Spin-Offs. If the Company distributes or dividends shares of Capital Stock of any class or series, or similar equity interest,
of or relating to an Affiliate, a Subsidiary or other business unit of the Company to all or substantially all holders of the Common
Stock (other than solely pursuant to a Common Stock Change Event, as to which Section 8(I) will apply), and such Capital
Stock or equity interest is listed or quoted (or will be listed or quoted upon the consummation of the transaction) on a U.S. national
securities exchange (a “Spin-Off”), then the Conversion Rate will be increased based on the following formula:

 

 

where:

 

CR0=the Conversion
Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such Spin-Off;

 

    -26-

     

    

CR1=the Conversion
Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

 

		FMV	=the product of (x) the average of the Last Reported Sale Prices per share or unit of the Capital
Stock or equity interests distributed in such Spin-Off over the ten (10) consecutive Trading Day period (the “Spin-Off
Valuation Period”) beginning on, and including, such Ex-Dividend Date (such average to be determined as if references
to Common Stock in the definitions of Last Reported Sale Price, Trading Day and Market Disruption Event were instead references
to such Capital Stock or equity interests); and (y) the number of shares or units of such Capital Stock or equity interests distributed
per share of Common Stock in such Spin-Off; and

 

		SP	=the average of the Last Reported Sale Prices per share of Common Stock for each Trading Day
in the Spin-Off Valuation Period.

 

The adjustment to the Conversion Rate pursuant to this
Section 8(F)(i)(3)(b) will be calculated as of the Close of Business on the last Trading Day of the Spin-Off Valuation Period
but will be given effect immediately after the Open of Business on the Ex-Dividend Date for the Spin-Off, with retroactive effect.
If a Note is converted and the Conversion Date occurs during the Spin-Off Valuation Period, then, notwithstanding anything to the
contrary in this Note, the Company will, if necessary, delay the settlement of such conversion until the second (2nd) Business
Day after the last day of the Spin-Off Valuation Period.

 

To the extent any dividend or distribution of the type
set forth in this Section 8(F)(i)(3)(b) is declared but not made or paid, the Conversion Rate will be readjusted to the
Conversion Rate that would then be in effect had the adjustment been made on the basis of only the dividend or distribution, if
any, actually made or paid.

 

(4)              
Cash Dividends or Distributions. If any cash dividend or distribution is made to all or substantially all holders of Common
Stock, then the Conversion Rate will be increased based on the following formula:

 

 

where:

 

    -27-

     

    

CR0=the Conversion
Rate in effect immediately before the Open of Business on the Ex-Dividend Date for such dividend or distribution;

 

CR1=the Conversion
Rate in effect immediately after the Open of Business on such Ex-Dividend Date;

 

		SP	=the Last Reported Sale Price per share of Common Stock on the Trading Day immediately before
such Ex-Dividend Date; and

 

		D	=the cash amount distributed per share of Common Stock in such dividend or distribution;

 

provided, however, that if D is equal
to or greater than SP, then, in lieu of the foregoing adjustment to the Conversion Rate, the Holder will receive, for each
$1,000 Principal Amount of this Note held by the Holder on the record date for such dividend or distribution, at the same time
and on the same terms as holders of Common Stock, the amount of cash that such Holder would have received if such Holder had owned,
on such record date, a number of shares of Common Stock equal to the Conversion Rate in effect on such record date.

 

To the extent such dividend or distribution is declared
but not made or paid, the Conversion Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment
been made on the basis of only the dividend or distribution, if any, actually made or paid.

 

(5)              
Tender Offers or Exchange Offers. If the Company or any of its Subsidiaries makes a payment in respect of a tender offer
or exchange offer for shares of Common Stock (other than solely pursuant to an odd-lot tender offer pursuant to Rule 13e-4(h)(5)
under the Exchange Act), and the value (determined as of the Expiration Time by the Board of Directors in good faith) of the cash
and other consideration paid per share of Common Stock in such tender or exchange offer exceeds the Last Reported Sale Price per
share of Common Stock on the Trading Day immediately after the last date (the “Expiration Date”) on which tenders
or exchanges may be made pursuant to such tender or exchange offer (as it may be amended), then the Conversion Rate will be increased
based on the following formula:

 

 

where:

 

CR0=the Conversion
Rate in effect immediately before the time (the “Expiration Time”) such tender or exchange offer expires;

 

CR1=the Conversion
Rate in effect immediately after the Expiration Time;

 

    -28-

     

    

		AC	=the aggregate value (determined as of the Expiration Time by the Board of Directors in good
faith) of all cash and other consideration paid for shares of Common Stock purchased or exchanged in such tender or exchange offer;

 

OS0=the number
of shares of Common Stock outstanding immediately before the Expiration Time (including all shares of Common Stock accepted for
purchase or exchange in such tender or exchange offer);

 

OS1=the number
of shares of Common Stock outstanding immediately after the Expiration Time (excluding all shares of Common Stock accepted for
purchase or exchange in such tender or exchange offer); and

 

		SP	=the average of the Last Reported Sale Prices per share of Common Stock over the ten (10) consecutive
Trading Day period (the “Tender/Exchange Offer Valuation Period”) beginning on, and including, the Trading Day
immediately after the Expiration Date;

 

provided, however, that the Conversion Rate
will in no event be adjusted down pursuant to this Section 8(F)(i)(5), except to the extent provided in the immediately
following paragraph. The adjustment to the Conversion Rate pursuant to this Section 8(F)(i)(5) will be calculated as of
the Close of Business on the last Trading Day of the Tender/Exchange Offer Valuation Period but will be given effect immediately
after the Expiration Time, with retroactive effect. If a Note is converted and the Conversion Date occurs on the Expiration Date
or during the Tender/Exchange Offer Valuation Period, then, notwithstanding anything to the contrary in this Note, the Company
will, if necessary, delay the settlement of such conversion until the second (2nd) Business Day after the last day of the Tender/Exchange
Offer Valuation Period.

 

To the extent such tender or exchange offer is announced
but not consummated (including as a result of the Company being precluded from consummating such tender or exchange offer under
applicable law), or any purchases or exchanges of shares of Common Stock in such tender or exchange offer are rescinded, the Conversion
Rate will be readjusted to the Conversion Rate that would then be in effect had the adjustment been made on the basis of only the
purchases or exchanges of shares of Common Stock, if any, actually made, and not rescinded, in such tender or exchange offer.

 

(ii)             
No Adjustments in Certain Cases.

 

(1)              
Where the Holder Participates in the Transaction or Event Without Conversion. Notwithstanding anything to the contrary in
Section 8(F)(i), the Company will not be obligated to adjust the Conversion Rate on account of a transaction or other event
otherwise requiring an adjustment pursuant to Section 8(F)(i) (other than a stock split or combination of the type set forth
in Section 8(F)(i)(1) or a tender or exchange offer of the type set forth in Section 8(F)(i)(5)) if the Holder participates,
at the same time and on the same terms as holders of Common Stock, and solely by virtue of being the Holder of this Note, in such
transaction or event without having to convert this Note and as if the Holder held a number of shares of Common Stock equal to
the product of (i) the Conversion Rate in effect on the related record date; and (ii) the aggregate Principal Amount (expressed
in thousands) of this Note held by this Holder on such date.

 

    -29-

     

    

(2)              
Certain Events. The Company will not be required to adjust the Conversion Rate except as provided in Section 8(F),
Section 8(H) or Section 8(I). Without limiting the foregoing, the Company will not be obligated to adjust the Conversion
Rate on account of:

 

(a)              
except as otherwise provided in Section 8(F), the sale of shares of Common Stock for a purchase price that is less than
the market price per share of Common Stock or less than the Conversion Price;

 

(b)              
the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or
interest payable on the Company’s securities and the investment of additional optional amounts in shares of Common Stock
under any such plan;

 

(c)              
the issuance of any shares of Common Stock or options or rights to purchase shares of Common Stock pursuant to any present or future
employee, director or consultant benefit plan or program of, or assumed by, the Company or any of its Subsidiaries;

 

(d)              
the issuance of any shares of Common Stock pursuant to any option, warrant, right or convertible or exchangeable security of the
Company outstanding as of the Issue Date (other than an adjustment pursuant to Section 8(F)(i)(3)(a) in connection with
the separation of rights under the Company’s stockholder rights plan existing, if any, as of the Issue Date);

 

(e)              
solely a change in the par value of the Common Stock; or

 

(f)               
accrued and unpaid interest on this Note.

 

(iii)           
Adjustments Not Yet Effective. Notwithstanding anything to the contrary in this Note, if:

 

(1)              
this Note is to be converted;

 

(2)              
the record date, effective date or Expiration Time for any event that requires an adjustment to the Conversion Rate pursuant to
Section 8(F)(i) has occurred on or before the Conversion Date for such conversion, but an adjustment to the Conversion Rate
for such event has not yet become effective as of such Conversion Date;

 

    -30-

     

    

(3)              
the Conversion Consideration due upon such conversion includes any whole shares of Common Stock; and

 

(4)              
such shares are not entitled to participate in such event (because they were not held on the related record date or otherwise),

 

then, solely for purposes of such conversion, the Company
will, without duplication, give effect to such adjustment on such Conversion Date. In such case, if the date on which the Company
is otherwise required to deliver the consideration due upon such conversion is before the first date on which the amount of such
adjustment can be determined, then the Company will delay the settlement of such conversion until the second (2nd) Business Day
after such first date.

 

(iv)            
Conversion Rate Adjustments where the Converting Holder Participates in the Relevant Transaction or Event. Notwithstanding
anything to the contrary in this Note, if:

 

(1)              
a Conversion Rate adjustment for any dividend or distribution becomes effective on any Ex-Dividend Date pursuant to Section
8(F)(i);

 

(2)              
a Note is to be converted;

 

(3)              
the Conversion Date for such conversion occurs on or after such Ex-Dividend Date and on or before the related record date;

 

(4)              
the Conversion Consideration due upon such conversion includes any whole shares of Common Stock based on a Conversion Rate that
is adjusted for such dividend or distribution; and

 

(5)              
such shares would be entitled to participate in such dividend or distribution (including pursuant to Section 8(C)(ii)),

 

then (x) such Conversion Rate adjustment will not be given
effect for such conversion; (y) the shares of Common Stock issuable upon such conversion based on such unadjusted Conversion Rate
will not be entitled to participate in such dividend or distribution; and (z) there will be added, to the Conversion Consideration
otherwise due upon such conversion, the same kind and amount of consideration that would have been delivered in such dividend or
distribution with respect to such shares of Common Stock had such shares been entitled to participate in such dividend or distribution.

 

(v)              
Stockholder Rights Plans. If any shares of Common Stock are to be issued upon conversion of any Note and, at the time of
such conversion, the Company has in effect any stockholder rights plan, then the Holder of such Note will be entitled to receive,
in addition to, and concurrently with the delivery of, the Conversion Consideration otherwise payable under this Note upon such
conversion, the rights set forth in such stockholder rights plan, unless such rights have separated from the Common Stock at such
time, in which case, and only in such case, the Conversion Rate will be adjusted pursuant to Section 8(F)(i)(3)(a) on account
of such separation as if, at the time of such separation, the Company had made a distribution of the type referred to in such Section
to all holders of the Common Stock, subject to readjustment in accordance with such Section if such rights expire, terminate or
are redeemed.

 

    -31-

     

    

(vi)            
Limitation on Effecting Transactions Resulting in Certain Adjustments. The Company will not engage in or be a party to any
transaction or event that would require the Conversion Rate to be adjusted pursuant to Section 8(F)(i), or Section 8(H)
to an amount that would result in the Conversion Price per share of Common Stock being less than the par value per share of Common
Stock.

 

(vii)         
Equitable Adjustments to Prices. Whenever any provision of this Note requires the Company to calculate the average of the
Last Reported Sale Prices, or any function thereof, over a period of multiple days (including to calculate an adjustment to the
Conversion Rate), the Company will make proportionate adjustments, if any, to such calculations to account for any adjustment to
the Conversion Rate pursuant to Section 8(F)(i) that becomes effective, or any event requiring such an adjustment to the
Conversion Rate where the Ex-Dividend Date or effective date, as applicable, of such event occurs, at any time during such period.

 

(viii)       
Calculation of Number of Outstanding Shares of Common Stock. For purposes of this Section 8(F), the number of shares
of Common Stock outstanding at any time will (i) include shares issuable in respect of scrip certificates issued in lieu of fractions
of shares of Common Stock; and (ii) exclude shares of Common Stock held in the Company’s treasury (unless the Company pays
any dividend or makes any distribution on shares of Common Stock held in its treasury).

 

(ix)            
Calculations. All calculations with respect to the Conversion Rate and adjustments thereto will be made to the nearest 1/10,000th
of a share of Common Stock (with 5/100,000ths rounded upward).

 

(x)              
Notice of Conversion Rate Adjustments. Upon the effectiveness of any adjustment to the Conversion Rate pursuant to Section
8(F)(i), the Company will promptly send notice to the Holder containing (i) a brief description of the transaction or other
event on account of which such adjustment was made; (ii) the Conversion Rate in effect immediately after such adjustment; and (iii)
the effective time of such adjustment.

 

(G)            
Voluntary Adjustments.

 

(i)                
Generally. To the extent permitted by law and applicable stock exchange rules, the Company, from time to time, may (but
is not required to) increase the Conversion Rate by any amount if (i) the Board of Directors determines in good faith that such
increase is either (x) in the best interest of the Company; or (y) advisable to avoid or diminish any income tax imposed on holders
of Common Stock or rights to purchase Common Stock as a result of any dividend or distribution of shares (or rights to acquire
shares) of Common Stock or any similar event; (ii) such increase is in effect for a period of at least twenty (20) Business Days;
and (iii) such increase is irrevocable during such period.

 

(ii)             
Notice of Voluntary Increases. If the Board of Directors determines to increase the Conversion Rate pursuant to Section
8(G)(i), then, no later than the first Business Day of the related twenty (20) Business Day period referred to in Section
8(G)(i), the Company will send notice to the Holder of such increase, the amount thereof and the period during which such increase
will be in effect.

 

    -32-

     

    

(H)            
Adjustments to the Conversion Rate in Connection with an Event of Default or Equity Triggering Event. If an Event of Default
or Equity Triggering Event occurs and the Conversion Date for the conversion of a Note occurs during the related Event of Default
Conversion Period or Equity Triggering Event Conversion Period, as applicable, then, subject to Section 8(J)(ii), the Conversion
Rate applicable to such conversion will be increased by a number of shares equal to the Event of Default/Equity Triggering Event
Additional Shares.

 

(I)               
Effect of Certain Recapitalizations, Reclassifications, Consolidations, Mergers and Sales.

 

(i)                
Generally. If there occurs:

 

(1)              
recapitalization, reclassification or change of the Common Stock (other than (x) changes solely resulting from a subdivision or
combination of the Common Stock, (y) a change only in par value or from par value to no par value or no par value to par value
and (z) stock splits and stock combinations that do not involve the issuance of any other series or class of securities);

 

(2)              
consolidation, merger, combination or binding or statutory share exchange involving the Company;

 

(3)              
sale, lease or other transfer of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole,
to any Person; or

 

(4)              
other similar event,

 

and, in each case, as a result of such occurrence, the
Common Stock is converted into, or is exchanged for, or represents solely the right to receive, other securities or other property
(including cash or any combination of the foregoing) (such an event, a “Common Stock Change Event,” and such
other securities or other property, the “Reference Property,” and the amount and kind of Reference Property
that a holder of one (1) share of Common Stock would be entitled to receive on account of such Common Stock Change Event (without
giving effect to any arrangement not to issue fractional shares of securities or other property), a “Reference Property
Unit”), then, notwithstanding anything to the contrary in this Note, at the effective time of such Common Stock Change
Event, (x) the Conversion Consideration due upon conversion of any Note will be determined in the same manner as if each reference
to any number of shares of Common Stock in this Section 8 (or in any related definitions) were instead a reference to the
same number of Reference Property Units; and (y) for purposes of the definition of “Fundamental Change,” the term “Common
Stock” and “common equity” will be deemed to mean the common equity, if any, forming part of such Reference Property.
For these purposes, (I) the Daily VWAP of any Reference Property Unit or portion thereof that consists of a class of common equity
securities will be determined by reference to the definition of “Daily VWAP,” substituting, if applicable, the Bloomberg
page for such class of securities in such definition; and (II) the Daily VWAP of any Reference Property Unit or portion thereof
that does not consist of a class of common equity securities, and the Last Reported Sale Price of any Reference Property Unit or
portion thereof that does not consist of a class of securities, will be the fair value of such Reference Property Unit or portion
thereof, as applicable, determined in good faith by the Company (or, in the case of cash denominated in U.S. dollars, the face
amount thereof).

 

    -33-

     

    

If the Reference Property consists of more than a single
type of consideration to be determined based in part upon any form of stockholder election, then the composition of the Reference
Property Unit will be deemed to be the weighted average of the types and amounts of consideration actually received, per share
of Common Stock, by the holders of Common Stock. The Company will notify the Holder of such weighted average as soon as practicable
after such determination is made.

 

At or before the effective date of such Common Stock Change
Event, the Company and the resulting, surviving or transferee Person (if not the Company) of such Common Stock Change Event (the
“Successor Person”) will execute and deliver such instruments or agreements that (x) provides for subsequent
conversions of this Note in the manner set forth in this Section 8(I); (y) provides for subsequent adjustments to the Conversion
Rate pursuant to Section 8(F) and Section 8 (H) in a manner consistent with this Section 8(I); and (z) contains
such other provisions as the Company reasonably determines are appropriate to preserve the economic interests of the Holder and
to give effect to the provisions of this Section 8(I). If the Reference Property includes shares of stock or other securities
or assets of a Person other than the Successor Person, then such other Person will also execute such instruments or agreements
and such instruments or agreements will contain such additional provisions the Company reasonably determines are appropriate to
preserve the economic interests of the Holder.

 

(ii)             
Notice of Common Stock Change Events. As soon as practicable after learning the anticipated or actual effective date of
any Common Stock Change Event, the Company will provide written notice to the Holder of such Common Stock Change Event, including
a brief description of such Common Stock Change Event, its anticipated effective date and a brief description of the anticipated
change in the conversion right of this Note.

 

(iii)           
Compliance Covenant. The Company will not become a party to any Common Stock Change Event unless its terms are consistent
with this Section 8(I).

 

(J)               
Limitations on Conversions.

 

(i)                
Beneficial Ownership Limitation. Notwithstanding anything to the contrary in this Note, no shares of Common Stock will be
issued upon conversion of this Note, including any Amortization Payment, or in lieu of payment of an Amortization Payment or payment
of Stated Interest due in cash pursuant to Section 5(B), this Note will not be convertible by the Holder, and the Company
will not effect any conversion of this Note or issue such shares, as applicable, in each case to the extent, and only to the extent,
that such issuance, convertibility or conversion would result in the Holder or a “person” or “group” (within
the meaning of Section 13(d)(3) of the Exchange Act) beneficially owning in excess of four and ninety nine hundredths percent (4.99%)
of the then-outstanding shares of Common Stock (the “Beneficial Ownership Limit”); provided, however,
that this Section 8(J)(i) will not apply to any Holder that is subject to Section 16(a) or (b) of the Exchange Act with
respect to the Company by virtue of being deemed to be a “director” or “officer” of the Company within
the meaning of Section 16 of the Exchange Act. For these purposes, beneficial ownership and calculations of percentage ownership
will be determined in accordance with Rule 13d-3 under the Exchange Act. For the avoidance of doubt, the limitations on the convertibility
of this Note pursuant to this Section 8(J)(i) will not, in themselves, cause this Note to cease to be outstanding (and interest
will continue to accrue on any portion of this Note that has been tendered for conversion and whose convertibility is suspended
pursuant to this Section 8(J)(i)), and such limitations will cease to apply if and when this Note’s convertibility
and conversion will not violate this Section 8(J)(i). Notwithstanding anything to the contrary in this Section 8(J)(i),
upon delivery of a written notice to the Company, the Holder may from time to time increase or decrease the Beneficial Ownership
Limit to any other percentage not in excess of nine and ninety nine hundredths percent (9.99%) as specified in such notice; provided
that any increase in the Beneficial Ownership Limit will not be effective until the sixty-first (61st) calendar day after the delivery
of such written notice.

 

    -34-

     

    

(ii)             
Stock Exchange Limitation. Notwithstanding anything to the contrary in this Note, until the Requisite Stockholder Approval
is obtained, in no event will the number of shares of Common Stock issued upon conversion of this Note, in lieu of payment of an
Amortization Payment or Stated Interest in cash pursuant to Section 5(B), or otherwise pursuant to this Note, including
without limitation pursuant to Section 5(G)(i) or Section 5(G)(ii), when aggregated with the Exchange Shares (as
defined in the Exchange Agreement) and any shares of Common Stock issued upon exercise of the New Warrant (as defined in the Exchange
Agreement) or the Right (as defined in the Exchange Agreement), exceed [__] [NTD: to be a prorated proportion of [__] shares
based on total amount of Notes issued] shares in the aggregate. If, after January 31, 2020, any one or more shares of Common
Stock are not delivered upon conversion of this Note, in lieu of payment of an Amortization Payment or Stated Interest in cash
pursuant to Section 5(B), or otherwise pursuant to this Note, including without limitation pursuant to Section 5(G)(i)
or Section 5(G)(ii), as a result of the operation of the preceding sentence (such shares, the “Withheld Shares”),
then (1) on the Conversion Settlement Date for such conversion, the Company will pay to the Holder, in addition to the Conversion
Consideration otherwise due upon such conversion, cash in an amount equal to the product of (x) the number of such Withheld Shares;
and (y) the Daily VWAP per share of Common Stock on the Conversion Date for such conversion; and (2) to the extent the Holder purchases
(in an open market transaction or otherwise) shares of Common Stock to deliver in settlement of a sale by the Holder of such Withheld
Shares, the Company will reimburse the Holder for (x) any brokerage commissions and other out-of-pocket expenses, if any, of the
Holder incurred in connection with such purchases and (y) the excess, if any, of (A) the aggregate purchase price of such purchases
over (B) the product of (I) the number of such Withheld Shares purchased by the Holder; and (II) the Daily VWAP on the Conversion
Date for such conversion.

all benefits or advantages of any such law and agrees that it will not, by resort to any such law, hinder, delay or impede the

efforts to obtain them, the records of its legal advisors and accountants (including the accountants’ work papers) and any
books of account, records, reports and other papers not contractually required of the Company to be confidential or secret, or
subject to attorney-client or other evidentiary privilege, and the Independent Investigator may make such copies and inspections
thereof as the Independent Investigator may reasonably request. The Company shall furnish the Independent Investigator with such
financial and operating data and other information with respect to the business and properties of the Company as the Independent
Investigator may reasonably request. The Company shall permit the Independent Investigator to discuss the affairs, finances and
accounts of the Company with, and to make proposals and furnish advice with respect thereto to, the Company’s officers, directors,
key employees and independent public accountants or any of them (and by this provision the Company authorizes said accountants

times, upon reasonable notice, and as often as may be reasonably requested.

adverse effect or materiality, which may not be breached in any respect) of the Note Exchange Agreement or the Exchange Agreement;
provided, however, that, except for a breach of Section 9(H), Section 9(I) or Section 9(J) hereof,

COMMON STOCK PURCHASE WARRANT

 

AMYRIS, INC. 

 

	Warrant Shares: [_______]	 	Issue Date: November 15, 2019
	 	 	Exchange Date: [__]

 

THIS COMMON STOCK PURCHASE WARRANT certifies that,
for value received, [__________] or its assigns (the “Holder”) is entitled, upon the terms and subject to the
limitations on exercise and the conditions hereinafter set forth, at any time on or after the Exchange Date (the “Initial
Exercise Date”) and on or prior to the close of business on the second anniversary of the Initial Exercise Date (the
“Termination Date”) but not thereafter, to subscribe for and purchase from Amyris, Inc., a Delaware corporation
(the “Company”), up to [________] shares (as subject to adjustment hereunder, the “Warrant Shares”)
of Common Stock. The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined
in Section 2(b). This Common Stock Purchase Warrant (including all Common Stock Purchase Warrants issued in exchange, transfer
or replacement hereof, this “Warrant”) is one of an issue of Common Stock Purchase Warrants issued pursuant
to that certain Exchange Agreement, dated as of December 30, 2019, by and between the Company and the Holder (the “Exchange
Agreement”) in exchange for that certain Senior Convertible Note due 2022, with an aggregate principal amount as of the
Exchange Date of $[____], and originally issued pursuant to that certain Securities Exchange Agreement, dated as of November 8,
2019, by and among the Company and the investors referred to therein, as amended from time to time.

 

Section 1.Definitions. Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in the Exchange Agreement, as such definitions are
in effect on December 30, 2019.

 

Section 2.Exercise.

 

a)                 
Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part,
at any time or times on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company of
a duly executed facsimile copy or PDF copy submitted by electronic (or e-mail attachment) of the Notice of Exercise in the form
annexed hereto (“Notice of Exercise”). Within two (2) Trading Days following the date of exercise as aforesaid,
the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable Notice of Exercise by wire transfer
or cashier’s check drawn on a United States bank unless the cashless exercise procedure specified in Section 2(c) below is
specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee
(or other type of guarantee or notarization) of any Notice of Exercise form be required. Notwithstanding anything herein to the
contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all
of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender
this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered
to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available
hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to
the applicable number of Warrant Shares purchased. The Company shall maintain records showing the number of Warrant Shares purchased
and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of
receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of
the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares
available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

 

    1

     

    

b)                 
Exercise Price. The exercise price per share of the Common Stock under this Warrant shall be $3.25, subject to adjustment
hereunder (the “Exercise Price”).

 

c)                                               
Cashless Exercise. Notwithstanding anything contained herein to the contrary, if a registration statement covering
the resale of the Warrant Shares subject to the applicable Notice of Exercise is not available for the resale of such Warrant Shares,
this Warrant may be exercised, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before
the Termination Date at the election of the Holder (in such Holder’s sole discretion) by means of a “cashless exercise”
in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing ((A-B) *
(X)) by (A), where:

 

(A) = as applicable: (i) the VWAP on
the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed
and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to
Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b)(64)
of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of the Holder, either
(y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the Bid Price of the
Common Stock on the Principal Market as reported by Bloomberg L.P. as of the time of the Holder’s execution of the applicable
Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered
within two (2) hours thereafter (including until two (2) hours after the close of “regular trading hours” on a Trading
Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice
of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 2(a) hereof after the
close of “regular trading hours” on such Trading Day;

 

(B) = the Exercise Price of this
Warrant, as adjusted hereunder; and

 

    2

     

    

(X) = the number of Warrant Shares
that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means
of a cash exercise rather than a cashless exercise.

 

If
Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9)
of the Securities Act of 1933, as amended (the “Securities Act”), the Warrant Shares shall take on the characteristics
of the Warrants being exercised, and the holding period of the Warrant Shares being issued may be tacked on to the holding period
of this Warrant.  The Company agrees not to take any position contrary to this Section 2(c).

 

“Bid Price” means,
for any security as of the particular time of determination, (a) the bid price for such security on the Principal Market as reported
by Bloomberg , L.P. as of such time of determination, or, if the Principal Market is not the principal securities exchange or trading
market for such security, the bid price of such security on the principal securities exchange or trading market where such security
is listed or traded as reported by Bloomberg, L.P. as of such time of determination (based on a Trading Day from 9:30 a.m. (New
York City time) to 4:02 p.m. (New York City time)), (b)  if OTCQB or OTCQX is the principal trading market on which such security
is then traded, the volume weighted average price of such security for such date (or the nearest preceding date) on OTCQB or OTCQX
as applicable, (c) if such security is not then listed or quoted for trading on OTCQB or OTCQX and if prices for such security
are then reported in the “Pink Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding
to its functions of reporting prices), the most recent bid price per share of such security so reported, or (d) in all other
cases, the fair market value of a share of such security as determined by an independent appraiser selected in good faith by the
Holder and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

 

“VWAP” means, for
any security as of any date, the dollar volume-weighted average price for such security on (a) the Principal Market (or, if the
Principal Market is not the principal trading market for such security, then on the principal securities exchange or securities
market on which such security is then traded) (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York
City time)), (b)  if OTCQB or OTCQX is the principal trading market on which such security is then traded, the volume weighted
average price of such security for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if such security
is not then listed or quoted for trading on OTCQB or OTCQX and if prices for such security are then reported in the “Pink
Sheets” published by OTC Markets Group, Inc. (or a similar organization or agency succeeding to its functions of reporting
prices), the most recent bid price per share of such security so reported, or (d) in all other cases, the fair market value
of a share of such security as determined by an independent appraiser selected in good faith by the Holder and reasonably acceptable
to the Company, the fees and expenses of which shall be paid by the Company.

 

    3

     

    

Notwithstanding anything herein to
the contrary, on the Termination Date, if a registration statement covering the resale of the Warrant Shares is not available for
the resale of the Warrant Shares, this Warrant shall be automatically exercised via cashless exercise pursuant to this Section
2(c).

 

		d)	Mechanics of Exercise.

 

i.                 
Delivery of Warrant Shares Upon Exercise. Warrant Shares purchased hereunder shall be transmitted by the transfer
agent of the Company (the “Transfer Agent”) to the Holder by crediting the account of the Holder’s or
its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”)
if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the
issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale
by the Holder without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery of a certificate,
registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to
which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise by the
date that is the earlier of (i) two (2) Trading Days after the delivery to the Company of the Notice of Exercise and (ii) one (1)
Trading Day after delivery of the aggregate Exercise Price to the Company (such date, the “Warrant Share Delivery Date”).
Upon delivery of the Notice of Exercise, 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 of delivery of the Warrant
Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within
two (2) Trading following delivery of the Notice of Exercise. If the Company fails for any reason to deliver to the Holder the
Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash,
as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the
Common Stock on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth
Trading Day after such liquidated damages begin to accrue) for each Trading Day commencing one Trading Day after such Warrant Share
Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer
agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable.

 

ii.                         Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at
the request of the Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver
to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant,
which new Warrant shall in all other respects be identical with this Warrant.

 

    4

     

    

iii.                       
Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares
pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

 

iv.                       
Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights
available to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance
with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date, and if after
such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage
firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which
the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to
the Holder the amount, if any, by which (x) the Holder’s total purchase price (including brokerage commissions, if any) for
the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the
Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at which the sell order
giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the
Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise shall be deemed
rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied
with its exercise and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase
price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price
giving rise to such purchase obligation of $10,000, under clause (A) of the immediately preceding sentence the Company shall be
required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder
in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss. Nothing herein shall limit the
Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares
of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof.

 

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

 

    5

     

    

vi.                       
Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue
or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses
shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may
be directed by the Holder; provided, however, that in the event that Warrant Shares are to be issued in a name other
than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto
duly executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any
Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar
functions) required for same-day electronic delivery of the Warrant Shares.

 

vii.                       
Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely
exercise of this Warrant, pursuant to the terms hereof.

 

e)       Holder’s
Exercise Limitations.

 

    6

     

    

i.                       
Notwithstanding anything to the contrary contained herein, the Company shall not effect any exercise of this Warrant, and
the Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent
that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together
with the Holder’s Affiliates (as defined in Rule 405 of the Securities Act), and any other Persons acting as a group together
with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)), would beneficially
own in excess of the Beneficial Ownership Limitation (as defined below).  For purposes of the foregoing sentence, the number
of shares of Common Stock beneficially owned by the Holder and its Affiliates and Attribution Parties shall include the number
of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall
exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of
this Warrant beneficially owned by the Holder or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of
the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other any stock
or securities (other than Options) directly or indirectly convertible into or exercisable or exchangeable for shares of Common
Stock (“Convertible Securities”) or any rights, warrants or options to subscribe for or purchase shares of Common
Stock or Convertible Securities (“Options”) subject to a limitation on conversion or exercise analogous to the
limitation contained herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties.  Except as set
forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that
the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and
the Holder is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation
contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities
owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable shall
be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination
of whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates and Attribution
Parties) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and
the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to
any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and
regulations promulgated thereunder. For purposes of this Section 2(e), in determining the number of outstanding shares of Common
Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent
periodic or annual report filed with the SEC, as the case may be, (B) a more recent public announcement by the Company or (C) a
more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. 
Upon the written or oral request of the Holder, the Company shall within two Trading Days confirm orally and in writing to the
Holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding shares of Common Stock
shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by
the Holder or its Affiliates or Attribution Parties since the date as of which such number of outstanding shares of Common Stock
was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The
Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e),
provided that the Beneficial Ownership Limitation shall in no event exceed 9.99% of the number of shares of the Common Stock outstanding
immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and
the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective
until the 61st day after such notice is delivered to the Company. The provisions of this paragraph shall be construed
and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or
any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or
to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in
this paragraph shall apply to a successor holder of this Warrant.

 

    7

     

    

ii.                       
Stock Exchange Limitation. Until the Requisite Stockholder Approval (as defined in the New Note) is obtained, in
no event will the number of shares of Common Stock issued upon exercise of this Warrant, when aggregated with the Exchange Shares
(as defined in the Exchange Agreement), any shares of Common Stock issued upon exercise of the Right (as defined in the Exchange
Agreement) and any shares of Common Stock issued upon conversion of the New Note or otherwise pursuant to the New Note, exceed
[__] [NTD: to be a prorated proportion of [__] shares based on total amount of New Notes issued] shares in the aggregate.
If, after January 31, 2020, any one or more shares of Common Stock are not delivered upon exercise of this Warrant as a result
of the operation of the preceding sentence (such shares, the “Withheld Shares”), then (1) on the Warrant Share
Delivery Date for such exercise, the Company will pay to the Holder cash in an amount equal to the product of (x) the number of
such Withheld Shares; and (y) the Daily VWAP (as defined in the New Note) per share of Common Stock on the applicable date of exercise;
and (2) to the extent the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in settlement
of a sale by the Holder of such Withheld Shares, the Company will reimburse the Holder for (x) any brokerage commissions and other
out-of-pocket expenses, if any, of the Holder incurred in connection with such purchases and (y) the excess, if any, of (A) the
aggregate purchase price of such purchases over (B) the product of (I) the number of such Withheld Shares purchased by the Holder;
and (II) the Daily VWAP on the applicable date of exercise.

 

Section 3.Certain Adjustments.

 

a)                 
Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend
or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities
payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company
upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines
(including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues by
reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price
shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares,
if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding
immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted
such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a)
shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend
or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

 

    8

     

    

b)                 
[INTENTIONALLY OMITTED]

 

c)                 
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time after
the Exchange Date the Company grants, issues or sells any Convertible Securities or Options 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 Beneficial Ownership Limitation)
immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or
sale of such Purchase Rights (provided, however, to the extent that the Holder’s right to participate in any such Purchase
Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate
in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right
to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its
right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

 

d)                 
Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any
dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of
return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or
options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction,
but excluding any dividend that results in adjustment to the Exercise Price pursuant to Section 3(a) above) (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 Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in
such Distribution (provided, however, to the extent that the Holder's right to participate in any such Distribution
would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate
in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution
to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if
ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

 

    9

     

    

e)                 
Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly,
in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially
all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange
offer (whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell,
tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the
outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively
converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more
related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation,
a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons whereby such other
Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held
by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to,
such stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then,
the Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction (as if the exercise of the Warrant occurred immediately prior to the occurrence
of such Fundamental Transaction), at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise
of this Warrant), the number of shares of common stock of the successor or acquiring corporation or shares of Common Stock of the
Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”)
receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant
is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise
of this Warrant). For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to
apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common
Stock in such Fundamental Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in
a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common
Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder
shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental
Transaction. Notwithstanding the foregoing, at the request of the Holder delivered at any time commencing on the earliest to occur
of (x) the public disclosure of any Fundamental Transaction, (y) the consummation of any Fundamental Transaction and (z) the Holder
first becoming aware of any Fundamental Transaction through the date that is ninety (90) days after the public disclosure of the
consummation of such Fundamental Transaction by the Company pursuant to a Current Report on Form 8-K filed with the SEC, the Company
or the Successor Person (as defined in the New Notes) (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 Black Scholes Value. Payment of such amounts shall be made
by the Company (or at the Company’s direction) to the Holder on or prior to the later of (x) the second (2nd)
Trading Day after the date of such request and (y) the date of consummation of such Fundamental Transaction. For the purpose of
this Warrant, “Black Scholes Value” means the value of the unexercised portion of this Warrant remaining on
the date of the Holder’s request pursuant to Section 3(e), which value is calculated using the Black Scholes Option
Pricing Model obtained from the “OV” function on Bloomberg utilizing (i) an underlying price per share equal to the
greater of (1) the highest Last Reported Sale Price (as defined in the New Notes) of the Common Stock during the period beginning
on the Trading Day immediately preceding the announcement of the applicable Fundamental Transaction (or the consummation of the
applicable Fundamental Transaction, if earlier) and ending on the Trading Day of the Holder’s request pursuant to Section 3(e)
and (2) the sum of the price per share being offered in cash in the applicable Fundamental Transaction (if any) plus the value
of the non-cash consideration being offered in the applicable Fundamental Transaction (if any), (ii) a strike price equal to the
Exercise Price in effect on the date of the Holder’s request pursuant to Section 3(e), (iii) a risk-free interest rate
corresponding to the U.S. Treasury rate for a period equal to the greater of (1) the remaining term of this Warrant as of the date
of the Holder’s request pursuant to Section 3(e) and (2) the remaining term of this Warrant as of the date of consummation
of the applicable Fundamental Transaction or as of the date of the Holder’s request pursuant to Section 3(e) if such
request is prior to the date of the consummation of the applicable Fundamental Transaction, (iv) a zero cost of borrow and (v)
an expected volatility equal to the greater of 75% and the 30 day volatility obtained from the “HVT” function on Bloomberg,
L.P. (determined utilizing a 365 day annualization factor) as of the Trading Day immediately following the earliest to occur of
(A) the public disclosure of the applicable Fundamental Transaction, (B) the consummation of the applicable Fundamental Transaction
and (C) the date on which the Holder first became aware of the applicable Fundamental Transaction.

f)                  
Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a
share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding
as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

g)                 
Notice to Holder.

 

i.           
Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3,
the Company shall within two (2) Trading Days deliver to the Holder by facsimile or email a notice setting forth the Exercise Price
after such adjustment and any resulting adjustment to the number of Warrant Shares and setting forth a brief statement of the facts
requiring such adjustment.

 

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

 

    12

     

    

Section 4.Transfer of Warrant.

 

a)                 
Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section
4(d) hereof and in Section 9 of the Exchange Agreement, this Warrant and all rights hereunder are transferable, in whole or in
part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment
of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient
to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company
shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination
or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion
of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary,
the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant
in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date the Holder
delivers an assignment form to the Company assigning this Warrant full. The Warrant, if properly assigned in accordance herewith,
may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

 

b)                 
New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid
office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued,
signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved
in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or
Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated
the original issue date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

 

c)                 
Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that
purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may
deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any
distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

 

Section 5.Miscellaneous.

 

a)                 
No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends
or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly
set forth in Section 3.

 

b)                 
Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to
the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock
certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

 

    13

     

    

c)                 
Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of
any right required or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised
on the next succeeding Business Day.

 

d)                 
Authorized Shares.

 

i.           
Share Reserve. During the period the Warrant is outstanding from and after the Initial Exercise Date, the Company
covenants that it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance
of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance
of this Warrant shall constitute full authority to its officers who are charged with the duty of issuing the necessary Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be
necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation,
or of any requirements of the Principal Market upon which the Common Stock may be listed. The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase
rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued,
fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof
(other than taxes in respect of any transfer occurring contemporaneously with such issue).

 

ii.           
No Impairment. Except and to the extent as waived or consented to by the Holder, the Company shall not by any action,
including, without limitation, amending its certificate of incorporation or through any reorganization, transfer of assets, consolidation,
merger, 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 Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against
impairment. Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares
above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action
as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant
Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions
or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform
its obligations under this Warrant.

 

    14

     

    

iii.           
Consents. Before taking any action which would result in an adjustment in the number of Warrant Shares for which
this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or
consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

 

e)                 
Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant
shall be determined in accordance with the provisions of the Exchange Agreement.

 

f)                  
Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not
registered and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities
laws.

 

g)                 
Nonwaiver and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part
of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies, notwithstanding
the fact that all rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with
any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts
as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including
those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing
any of its rights, powers or remedies hereunder.

 

h)                 
Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the
Company shall be delivered in accordance with the notice provisions of the Exchange Agreement.

 

i)                  
Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise
this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to
any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability
is asserted by the Company or by creditors of the Company.

 

j)                  
Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would
not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees
to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

 

    15

     

    

k)                 
Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced
hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors
and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time
of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

 

l)                  
Amendment. This Warrant may be modified or amended or the provisions hereof waived with the written consent of the
Company and the Holder.

 

m)              
Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective
and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such
provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions
or the remaining provisions of this Warrant.

 

n)                 
Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose,
be deemed a part of this Warrant.
