COMMON STOCK PURCHASE WARRANT

 

AMYRIS, INC. 

 

	Warrant Shares: 431,378	Issue Date: May 10, 2019

 

THIS COMMON STOCK PURCHASE WARRANT (this “Warrant”)
certifies that, for value received, Silverback Opportunistic Credit Master Fund Limited
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 date hereof (the “Initial Exercise Date”) and
on or prior to the close of business on the two (2) year 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 four hundred thirty one thousand three hundred and seventy eight (431,378) 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).

 

Section 1.Definitions. Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in that certain Exchange Agreement (the “Exchange
Agreement”), dated May 10, 2019, among the Company and the Holder, as such definitions are in effect on May 10, 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 $5.02, 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,
at any time after the six month anniversary of the Initial Exercise Date, 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 Trading 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;

 

    	2

    

    

 

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

 

(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, 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 date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or
quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading
Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (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 not a Trading Market, the volume weighted
average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common
Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock 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 the Common Stock so reported, or (d) in all other cases, the fair market value
of a share of Common Stock 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 date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted
on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date)
on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (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 not a Trading Market, the
volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable,
(c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock 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 the Common Stock so reported, or (d) in all
other cases, the fair market value of a share of Common Stock 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.

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 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.

 

    	4

    

    

 

ii.                    
Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at
the request of a 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.

 

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 a Holder’s
right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon
exercise of the Warrant as required pursuant to the terms hereof.

 

    	5

    

    

 

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.

 

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.

 

    	6

    

    

 

e)       Holder’s
Exercise Limitations. Notwithstanding anything to the contrary contained herein, the Company shall not effect any exercise
of this Warrant, and a 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, 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 Common Stock Equivalents) 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, a 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 Commission, 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 a Holder, the Company
shall within two Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. 
In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise
of securities of the Company, including this 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 in no event exceeds 9.99%
of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock
upon 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

    

    

 

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.

 

b)                 
[INTENTIONALLY OMITTED]

 

c)                 
Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time after
the Original Issue Date the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants,
securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”),
then each 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).

 

    	8

    

    

 

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 Conversion 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).

 

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.

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 Commission 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.

Section 4.Transfer of Warrant.

 

a)                 
Transferability. Subject to compliance with any applicable securities laws, 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.

 

    	11

    

    

 

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.

 

d)                 
[INTENTIONALLY OMITTED]

 

e)                 
Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring
this Warrant and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and
not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act
or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

 

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.

 

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.

 

    	12

    

    

 

d)                 
Authorized Shares.

 

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 Trading 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).

 

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.

 

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.

 

    	13

    

    

 

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.

 

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.

 

    	14

    

    

 

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.

WARRANT TO PURCHASE COMMON STOCK

 

	Company:	Amyris, Inc., a Delaware corporation
	Number of Shares:	352,638
	Class of Stock:	Common Stock
	Warrant Price:	$4.56 per share
	Issue Date:	May 14, 2019
	Expiration Date:	The 2nd anniversary after the
Issue Date

 

THIS WARRANT TO PURCHASE COMMON STOCK (this
“Warrant”) certifies that, for good and valuable consideration, FORIS
VENTURES, LLC (together with any registered holder from time to time of this Warrant or any holder of the shares issuable
or issued upon exercise of this Warrant, “Holder”) is entitled to purchase the number of fully paid and nonassessable
shares of the class of securities of the Company at the Warrant Price, all as set forth above and as adjusted pursuant to Article
2 of this Warrant, subject to the provisions and upon the terms and conditions set forth in this Warrant. This Warrant is issued
in connection with the Exchange Agreement, dated as of May 10, 2019, as amended from time to time (the “Exchange Agreement”),
between Company and the Holder. Capitalized terms used but not otherwise defined herein shall have the meaning ascribed to them
in the Exchange Agreement.

 

ARTICLE
1 EXERCISE.

 

1.1.           
Conditions to Exercise. Holder may not exercise this Warrant unless and
until the exercise of this Warrant, and the issuance of the Shares (as defined below) upon exercise hereof, has been approved
by the Company’s stockholders at a duly called and held annual or special meeting of the stockholders of the Company in accordance
with the Restated Certificate of Incorporation and Restated Bylaws of the Company and otherwise satisfies the requirements of Nasdaq
Stock Market Rule 5635 (the “Exercise Condition”). Upon satisfaction of the Exercise Condition and thereafter
up to and including the Expiration Date, this Warrant shall be exercisable for three hundred fifty two thousand six hundred and
thirty eight (352,638) shares of the Company’s Common Stock (subject to adjustment as provided herein) (the “Shares”).
The number of Shares and the Warrant Price are subject to adjustment as provided herein, and all references to “Shares”
and “Warrant Price” herein shall be deemed to include any such adjustment or series of adjustments.

 

    

    

    

 

1.2.           
Method of Exercise.

 

(a)              
Mechanics. This Warrant may be exercised by the Holder on any day on or after the date the Exercise Condition
has been satisfied (an “Exercise Date”), in whole or in part, by delivery (whether via facsimile or otherwise)
of a written notice, in the form attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s
election to exercise this Warrant. Within one (1) Trading Day following an exercise of this Warrant as aforesaid, the Holder shall
deliver payment to the Company of an amount equal to the Exercise Price in effect on the date of such exercise multiplied by the
number of Shares as to which this Warrant was so exercised (the “Aggregate Exercise Price”) in cash or via wire
transfer of immediately available funds if the Holder did not notify the Company in such Exercise Notice that such exercise was
made pursuant to a Cashless Exercise (as defined in Section 1.3). The Holder shall not be required to deliver the original of this
Warrant in order to effect an exercise hereunder. Execution and delivery of an Exercise Notice with respect to less than all of
the Shares shall have the same effect as cancellation of the original of this Warrant and issuance of a new Warrant evidencing
the right to purchase the remaining number of Shares. Execution and delivery of an Exercise Notice for all of the then-remaining
Shares shall have the same effect as cancellation of the original of this Warrant after delivery of the Shares in accordance with
the terms hereof. On or before the third (3rd) Trading Day following the date on which the Company has received such Exercise Notice,
the Company shall (X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”)
Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of shares of Common Stock
to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC
through its Deposit/Withdrawal at Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated
Securities Transfer Program, upon the request of the Holder, issue and deliver (via reputable overnight courier) to the address
as specified in the Exercise Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares
of Common Stock to which the Holder shall be entitled pursuant to such exercise. Upon delivery of an Exercise Notice, the Holder
shall be deemed for all corporate purposes to have become the holder of record of the Shares with respect to which this Warrant
has been exercised, irrespective of the date such Shares are credited to the Holder’s DTC account or the date of delivery
of the certificates evidencing such Shares (as the case may be). If this Warrant is submitted in connection with any exercise pursuant
to this Section 1 and the number of Shares represented by this Warrant submitted for exercise is greater than the number of Shares
being acquired upon an exercise and upon surrender of this Warrant to the Company by the Holder, then, at the request of the Holder,
the Company shall as soon as practicable and in no event later than two (2) Business Days after any exercise and at its own expense,
issue and deliver to the Holder (or its designee) a new Warrant representing the right to purchase the number of Shares purchasable
immediately prior to such exercise under this Warrant, less the number of Shares with respect to which this Warrant is exercised.
No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common
Stock to be issued shall be rounded down to the nearest whole number. The Company shall pay any and all transfer, stamp, issuance
and similar taxes, costs and expenses (including, without limitation, fees and expenses of the Transfer Agent) that may be payable
with respect to the issuance and delivery of Shares upon exercise of this Warrant. Notwithstanding the foregoing, except in the
case where an exercise of this Warrant is validly made pursuant to a Cashless Exercise), the Company’s failure to deliver
Shares to the Holder on or prior to the later of ((i) two (2) Trading Days after receipt of the applicable Exercise Notice and
(ii) one (1) Trading Day after the Company’s receipt of the Aggregate Exercise Price (or valid notice of a Cashless Exercise
(such later date, the “Share Delivery Deadline”) shall not be deemed to be a breach of this Warrant.

 

    	2

    

    

 

(b)             
Company’s Failure to Timely Deliver Securities. If the Company shall fail, for any reason or for
no reason, on or prior to the Share Delivery Deadline, if the Transfer Agent is not participating in the DTC Fast Automated Securities
Transfer Program, to issue and deliver to the Holder (or its designee) a certificate for the number of Shares to which the Holder
is entitled and register such Shares on the Company’s share register or, if the Transfer Agent is participating in the DTC
Fast Automated Securities Transfer Program, to credit the balance account of the Holder or the Holder’s designee with DTC
for such number of Shares to which the Holder is entitled upon the Holder’s exercise of this Warrant (as the case may be),
and if on or after such Share Delivery Deadline the Holder purchases (in an open market transaction or otherwise) shares of Common
Stock to deliver in satisfaction of a sale by the Holder of all or any portion of the number of shares of Common Stock issuable
upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”), then, in addition to
all other remedies available to the Holder, the Company shall, within two (2) Business Days after the Holder’s request and
in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price
(including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased (including,
without limitation, by any other Person in respect, or on behalf, of the Holder) (the “Buy-In Price”), at which
point the Company’s obligation to so issue and deliver such certificate (and to issue such shares of Common Stock) or credit
the balance account of such Holder or such Holder’s designee, as applicable, with DTC for the number of Shares to which the
Holder is entitled upon the Holder’s exercise hereunder (as the case may be) (and to issue such Shares) shall terminate,
or (ii) promptly honor its obligation to so issue and deliver to the Holder a certificate or certificates representing such Shares
or credit the balance account of such Holder or such Holder’s designee, as applicable, with DTC for the number of Shares
to which the Holder is entitled upon the Holder’s exercise hereunder (as the case may be) and pay cash to the Holder in an
amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Shares multiplied by (B) the lowest
Closing Sale Price of the Common Stock on any Trading Day during the period commencing on the date of the applicable Exercise Notice
and ending on the date of such issuance and payment under this clause (ii). Nothing 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 certificates representing shares of Common
Stock (or to electronically deliver such shares of Common Stock) upon the exercise of this Warrant as required pursuant to the
terms hereof.

 

1.3.           
Cashless Exercise Right. Notwithstanding anything contained herein to the contrary, if a registration
statement covering the resale of the Shares subject to the applicable Exercise Notice is not available for the resale of such Shares,
at any time after the six month anniversary of the satisfaction of the Exercise Condition and on or before the Expiration Date,
this Warrant may be exercised, in whole or in part, at the election of the Holder in its sole discretion, by means of a “cashless
exercise” in which the Holder shall be entitled to receive a number of Shares determined
according to the following formula (a “Cashless Exercise”):

 

    	3

    

    

 

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

 

For purposes of the foregoing formula:

 

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

 

B= the fair market value of each Share
shall be the average for the five Trading Days immediately prior to the date of determination thereof of the last reported sale
price regular way on each such day, or, in the case no such sale takes place on any such day, the average of the reported closing
bid and asked prices regular way of the shares of Common Stock on such day, in each case as quoted on the Principal Market, as
reported by Bloomberg or such other principal securities exchange or inter-dealer quotation system on which the shares of Common
Stock are then traded.

 

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

 

1.4.           
Delivery of Certificate and New Warrant. Promptly after Holder exercises or converts this Warrant, and,
if applicable, the Company receives payment of the aggregate Warrant Price, the Company shall deliver to Holder certificates for
the Shares acquired and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing
the Shares not so acquired. Holder shall be deemed to own and have all of the rights associated with any Shares or other securities
or property to which it is entitled pursuant to this Warrant upon the exercise or conversion of the Warrant in accordance with
this Article 1.

 

1.5.           
Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and in the case of loss, theft or destruction, on delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of mutilation on surrender and cancellation of this Warrant,
the Company shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

 

1.6.           
Treatment of Warrant Upon Acquisition of Company.

 

1.6.1       
“Acquisition”. For the purpose of this Warrant, “Acquisition” shall mean the occurrence
of any of the following: (i) the consolidation of the Company with, or the merger of the Company with or into, another “person”
(as such term is used in Rule 13d-3 and Rule 13d-5 of the Exchange Act), or the sale, lease, transfer, conveyance or other disposition,
in one or a series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries taken
as a whole, or the consolidation of another “person” with, or the merger of another “person” into, the
Company, other than in each case pursuant to a transaction in which the “persons” that “beneficially owned”
(as such term is defined in Rule 13d-3 and Rule 13d-5 under the Exchange Act), directly or indirectly, the Voting Shares (as defined
below) of the Company immediately prior to the transaction “beneficially own”, directly or indirectly, Voting Shares
representing at least a majority of the total voting power of all outstanding classes of voting stock of the surviving or transferee
person; (ii) the adoption by the Company of a plan relating to the liquidation or dissolution of the Company; (iii) the
consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person”
becomes the “beneficial owner” directly or indirectly, of more than 50% of the Voting Shares of the Company (measured
by voting power rather than number of shares); or (iv) the first day on which a majority of the members of the Company’s
Board of Directors (the “Board”) does not consist of Continuing Directors (as defined below). For the purposes of this
Article 1.7.1, (i) “Voting Shares” of any person shall mean capital shares or capital stock of such person which ordinarily
has voting power for the election of directors (or persons performing similar functions) of such person, whether at all times or
only so long as no senior class of securities has such voting power by reason of any contingency, and (ii) “Continuing Director”
shall mean, as of any date of determination, any member of the Board who (i) was a member of the Board on the Issue Date or (ii)
was nominated for election or elected to the Board with the approval of a majority of the Continuing Directors who were members
of the Board at the time of such nomination or election and who voted with respect to such nomination or election; provided that
a majority of the members of the Board voting with respect thereto shall at the time have been Continuing Directors.

 

    	4

    

    

 

1.6.2       
Treatment of Warrant at Acquisition. In the event of an Acquisition, either (a) Holder shall exercise
or convert his Warrant in full with respect to all remaining Shares for which the Warrant is then exercisable and such exercise
or conversion will be deemed effective immediately prior to the consummation of such Acquisition or (b) if Holder elects not to
exercise or convert the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide
Holder with written notice of the foregoing (together with such reasonable information as Holder may request in connection with
such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior
to the closing of the proposed Acquisition.

 

1.7.           
Insufficient Authorized Shares. If at any time while the Warrant remains outstanding the Company does
not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance
upon exercise of the Warrant at least a number of shares of Common Stock equal to 100% (the “Required Reserve Amount”)
of the number of shares of Common Stock as shall from time to time be necessary to effect the exercise of the Warrant then outstanding,
then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock
to an amount sufficient to allow the Company to reserve the Required Reserve Amount for the Warrant then outstanding.

 

ARTICLE
2 ADJUSTMENTS TO THE SHARES.

 

2.1.           
Stock Dividends, Splits, Etc. If the Company declares or pays a dividend on the Shares payable in common
stock of the Company, or other securities, then upon exercise of this Warrant, for each Share acquired, Holder shall receive, without
cost to Holder, the total number and kind of shares of common stock of the Company to which Holder would have been entitled had
Holder owned the Shares of record as of the date the dividend occurred. If the Company subdivides the Shares by reclassification
or otherwise into a greater number of shares or takes any other action which increases the amount of stock for which this Warrant
is exercisable, the number of Shares subject to the Warrant shall be proportionately increased and the Warrant Price shall be proportionately
decreased. If the outstanding shares are combined or consolidated, by reclassification or otherwise, into a lesser number of shares,
the Warrant Price shall be proportionately increased and the number of Shares subject to the Warrant shall be proportionately decreased.

2.2.           
Reclassification, Exchange, Combinations or Substitution. Upon any reclassification, exchange, substitution,
or other event that results in a change of the number and/or class of the securities issuable upon exercise or conversion of this
Warrant (other than an Acquisition which is subject to the provisions of Article 1.6), Holder shall be entitled to receive, upon
exercise or conversion of this Warrant the number and kind of securities and property that Holder would have received for the Shares
if this Warrant had been exercised immediately before such reclassification, exchange, substitution, or other event. The Company
or its successor shall promptly issue to Holder an amendment to this Warrant setting forth the number and kind of such new securities
or other property issuable upon exercise or conversion of this Warrant as a result of such reclassification, exchange, substitution
or other event that results in a change of the number and/or class of securities issuable upon exercise or conversion of this Warrant.
The amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the Warrant Price and to the number of securities
or property issuable upon exercise of the new Warrant. The provisions of this Article 2.2 shall similarly apply to successive reclassifications,
exchanges, substitutions, or other events.

 

2.3.           
Rights Upon Distribution of Assets. 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 (which dividend or other distribution has
not already been given to the Holder of the Warrant), by way of return of capital or otherwise (including, without limitation,
any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate
rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance
of this Warrant and prior to the Expiration Date, then, in each such case:

 

(a)              
any Warrant Price in effect immediately prior to the close of business on the record date fixed for the determination
of holders of shares of Common Stock entitled to receive the Distribution shall be reduced, effective as of the close of business
on such record date, to a price determined by multiplying such Warrant Price by a fraction of which (i) the numerator shall
be the Closing Bid Price of the shares of Common Stock on the Trading Day immediately preceding such record date minus the value
of the Distribution (as determined in good faith by the Company’s Board of Directors) applicable to one share of Common Stock,
and (ii) the denominator shall be the Closing Bid Price of the shares of Common Stock on the Trading Day immediately preceding
such record date; and

 

(b)              the
number of Shares shall be increased to a number of shares equal to the number of shares of Common Stock obtainable
immediately prior to the close of business on the record date fixed for the determination of holders of shares of
Common Stock entitled to receive the Distribution multiplied by the reciprocal of the fraction set forth in the immediately
preceding paragraph (a); provided that in the event that the Distribution is of shares of Common Stock(“Other Shares of
Common Stock”) of a company whose common shares are traded on a national securities exchange or a national automated
quotation system, then the Holder may elect to receive a warrant to purchase Other Shares of Common Stock in lieu of an
increase in the number of Shares, the terms of which shall be identical to those of this Warrant, except that such warrant
shall be exercisable into the number of shares of Other Shares of Common Stock that would have been payable to the Holder
pursuant to the Distribution had the Holder exercised this Warrant immediately prior to such record date and with an
aggregate warrant price equal to the product of the amount by which the warrant price of this Warrant was decreased with
respect to the Distribution pursuant to the terms of the immediately preceding paragraph (a) and the number of Shares
calculated in accordance with the first part of this paragraph (b).

2.4.           
Other Adjustment Events. If any event occurs of the type contemplated by the provisions of this Article
2 but not expressly provided for by such provisions, then the Company’s Board of Directors will make an appropriate adjustment
in the Warrant Price and the number of Shares so as to protect the rights of the Holder; provided that no such adjustment pursuant
to this Article 2.4 will increase the Warrant Price or decrease the number of Shares as otherwise determined pursuant to this Article
2.

 

2.5.           
No Impairment. Without the consent of the Holder, the Company shall not by amendment of its Certificate
of Incorporation or through a 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 to be observed or performed
under this Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this Article
2 and in taking all such action as may be necessary or appropriate to protect Holder’s rights under this Article against
impairment.

 

2.6.           
Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion of this Warrant
and the number of Shares to be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon
any exercise or conversion of the Warrant, the Company shall eliminate such fractional share interest by paying Holder in cash
equivalent to the amount computed by multiplying the fractional interest by the fair market value of a full Share.

 

2.7.           
Certificate as to Adjustments. Upon each adjustment of the Warrant Price and Shares, the Company shall
promptly notify Holder in writing, and, at the Company’s expense, promptly compute such adjustment, and furnish Holder with
a certificate of its Chief Financial Officer, Corporate Secretary or a senior financial officer setting forth such adjustment and
the facts upon which such adjustment is based. The Company shall, upon written request, furnish Holder a certificate setting forth
the Warrant Price and Shares in effect upon the date thereof and the series of adjustments leading to such Warrant Price and Shares.
