	Warrant Shares: 31,970	Initial Exercise Date: August 26, 2016
	 	 
	Warrant No.: PA-2	Issue Date: August 26, 2015


 


THIS COMMON STOCK PURCHASE
WARRANT (the “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  August 26, 2016 (the “Initial Exercise Date”) and on or prior
to the close of business on the five (5) year anniversary of the Issue Date (the “Termination Date”) but not
thereafter, to subscribe for and purchase from Ceres, Inc., a Delaware corporation (the “Company”), up to 31,970
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
Warrant is issued by the Company as of the date hereof pursuant to (i) Section 1 of the Placement Agency Agreement, dated as of
August 20, 2015 (the “Placement Agency Agreement”), between the Company and Ladenburg Thalmann & Co. Inc.
(“Ladenburg”) and (ii) Section 4(a)(ii) of the Investment Banking Agreement, dated July 13, 2015, between the
Company and Ladenburg.


 


Section 1.          Definitions.  Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the
“Purchase Agreement”), dated August 20, 2015, among the Company and the purchasers signatory thereto.

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 pursuant to
the notice provisions in the Placement Agency Agreement (or such other office or agency of the Company as it may designate by notice
in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed copy
by e-mail attachment of the Notice of Exercise in the form annexed hereto as Exhibit A and within three (3) Trading Days
of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate Exercise
Price of the shares of Common Stock thereby purchased by wire transfer or cashier’s check drawn on a United States bank or,
if available, pursuant to the cashless exercise procedure specified in Section 2(c) below. 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 Holder and 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.


 


b)          Exercise
Price.  The exercise price per share of the Common Stock under this Warrant shall be $1.83, subject to adjustment
hereunder (the “Exercise Price”).


 


c)          Cashless
Exercise.  If at any time on or after the Initial Exercise Date, there is no effective registration statement registering,
or no current prospectus available for, the resale of the Warrant Shares by the Holder, then this Warrant may also be exercised,
in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall follow the exercise procedure
set out in paragraph (a) above and shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing
[(A-B) (X)] by (A), where:


 


(A) = the VWAP
on the Trading Day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless
exercise,” as set forth in the applicable Notice of Exercise;


 


(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, the Warrant Shares shall take on the characteristics of the Warrants being exercised, and the holding period
of the Warrants being exercised may be tacked on to the holding period of the Warrant Shares, subject to applicable law.  The
Company agrees not to take any position contrary to this Section 2(c), subject to applicable law.


 


“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, 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 Holders
of a majority in interest of the Securities then outstanding 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, this Warrant shall be automatically exercised via cashless exercise pursuant
to this Section 2(c) and upon any such exercise, the Holder shall surrender this Warrant to the Company for cancellation within
three (3) Trading Days.

d)          Mechanics
of Exercise.


 


i.            Delivery
of Warrant Shares Upon Exercise.  Subject to Section 2(e), 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 three
(3) Trading Days after the delivery to the Company of the Notice of Exercise (such date, the “Warrant Share Delivery Date”).  
The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall
be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised, with
payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder,
if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having been paid.  Subject to Section 2(e),
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),
$5 per Trading Day (increasing to $10 per Trading Day on the fifth Trading Day after such liquidated damages begin to accrue) for
each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder rescinds such exercise.


 


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.


 




    	4 



     


    

 


iv.         Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise.  Subject to Section 2(e), 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 by the Warrant Share Delivery Date, and if after
such Warrant Share Delivery 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 by (2) the actual
sale 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.


 


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 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 as Exhibit
B 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.


 




    	5 



     


    

 


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.  Notwithstanding any other provision of this Section 2, 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), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below).  For purposes
of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Affiliates shall include,
but not be limited to, 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 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.  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 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 of which portion of this Warrant is exercisable, in each case subject to
the Beneficial Ownership Limitation.  To ensure compliance with this restriction, each Holder shall be deemed to represent
to the Company each time it delivers a Notice of Exercise that such Notice of Exercise has not violated the restrictions set forth
in this paragraph, and the Company shall have no obligation to verify or confirm the accuracy of such determination.  
In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d)
of the Exchange Act and the rules and regulations promulgated thereunder.  For purposes of this Section 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 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.

Section 3.          Certain
Rights.


 


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.


 




    	7 



     


    

 


b)          [Reserved]


 


c)          Subsequent
Rights Offerings.  In addition to any adjustments pursuant to Section 3(a) above, if at any time 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 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) (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. To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution,
such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.


 




    	8 



     


    

 


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, upon any subsequent
exercise of this Warrant, 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, 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 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 anything to the contrary, in the event of a Fundamental Transaction
that is (1) an all cash transaction, (2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Exchange Act,
or (3) a Fundamental Transaction involving a person or entity not traded on a national securities exchange, the Company or any
Successor Entity (as defined below) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30
days after, the consummation of the Fundamental Transaction, purchase this Warrant from the Holder by paying to the Holder an amount
of cash equal to the Black Scholes Value of the remaining unexercised portion of this Warrant on the date of the consummation of
such Fundamental Transaction.  “Black Scholes Value” means the value of this Warrant based on the
Black and Scholes Option Pricing Model obtained from the “OV” function on Bloomberg, L.P. (“Bloomberg”)
determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free
interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement
of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and
the 100 day volatility obtained from the HVT function on Bloomberg as of the Trading Day immediately following the public announcement
of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the sum of the
price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental
Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental
Transaction and the Termination Date.  The Company shall cause any successor entity in a Fundamental Transaction in which
the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the
Company under this Warrant and the other Transaction Documents in accordance with the provisions of this Section 3(e) pursuant
to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable
delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this
Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this
Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity)
equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations
on the exercise of this Warrant) prior to such Fundamental Transaction, and with an exercise price which applies the exercise price
hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to
such Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such exercise
price being for the purpose of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental
Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental
Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer
instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations
of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been
named as the Company herein.

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 promptly
mail to the Holder 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

Section 4.          Transfer
of Warrant.


 


a)   Transferability.  Neither
this Warrant nor any Warrant Shares issued upon exercise of this Warrant shall be sold, transferred, assigned, pledged or hypothecated
, or be the subject of any hedging, short sale, derivative, put or call transaction that would result in the effective economic
disposition of the securities by any person for a period of 180 days immediately following the date of effectiveness or commencement
of sales of the offering pursuant to which this Warrant is being issued, except the transfer of any security:


 


		(i)	by operation of law or by reason of reorganization of the Company;



 


		(ii)	to any FINRA member firm participating in the offering and the officers and partners thereof, if
all securities so transferred remain subject to the lock-up restriction in the first paragraph of this Section 4(a) for the remainder
of the time period;



 


		(iii)	if the aggregate amount of securities of the Company held by the Holder or related persons do not
exceed 1% of the securities offered in the offering;



 


		(iv)	that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided
that no participating member manages or otherwise directs investments by the fund, and participating members in the aggregate do
not own more than 10% of the equity in the fund; or



 


		(v)	the exercise or conversion of any security, if all securities received remain subject to the lock-up
restriction in the first paragraph of this Section 4(a) for the remainder of the time period.



 


Subject to compliance
with any applicable securities laws, the conditions set forth in Section 4(d) hereof and the restriction set out in the first paragraph
of this Section 4(a), this Warrant and all rights hereunder (including, without limitation, any registration rights) 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)          Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer
of this Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and
under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or
current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer,
that the Holder or transferee of this Warrant, as the case may be, comply with the provisions of Section 5.7 of the Purchase Agreement.


 


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.


 




    	12 



     


    

 


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.


 


d)          Authorized
Shares.  


 


The Company covenants
that, during the period the Warrant is outstanding, 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).  


 




    	13 



     


    

 


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.


 


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


 




    	14 



     


    

 


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.


 


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.
