	Warrant Shares: _______	Initial Exercise Date: July  , 2014

 

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 the date hereof (the “Initial Exercise Date”) and on or prior to the close of business on the five
(5) year anniversary of the Initial Exercise Date (the “Termination Date”) but not thereafter, to subscribe
for and purchase from Microlin Bio, Inc., a Delaware corporation (the “Company”), up to ______ [100% of Units
purchased by such holder in the offering] shares (as subject to adjustment hereunder, the “Warrant Shares”)
of Common Stock of the Company. 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).

 

Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Warrant Agreement (as defined
below).

a)            “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 the OTC Bulletin Board is not a Trading Market,
the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board,
(c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are
then reported in the “Pink Sheets” published by Pink 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.

c)            “Trading
Market” means any market or exchange on which the Common Stock is listed or quoted for trading on the date in question.

 

Section 2.                      Exercise.

 

a)  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 VStock Transfer, LLC (the “Warrant
Agent”) (which term includes any successor warrant agent under the Warrant Agreement described below) at its
offices at 18 Lafayette Place, Woodmere, New York, of a duly executed facsimile copy of the Notice of Exercise Form annexed
hereto (or such other form as the Warrant Agent may prescribe) and surrender of this Warrant or, in the case of a Book-Entry
Warrant Certificate, a copy of the Notice of Exercise Form annexed hereto properly delivered by the Participant in accordance
with the procedures of the Depository Trust Company (the “Depository”). Within three (3) 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, made payable to
the Company, unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of
Exercise. 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 Warrant Agent shall maintain
records showing the number of Warrant Shares purchased and the date of such purchases and, in the case of a Book-Entry
Warrant Certificate, the Warrant Agent shall maintain records showing the notation that shall be made to the records
maintained by the Depository, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate,
evidencing the balance, if any, of the Warrants remaining after an exercise of the Warrants. The Warrant Agent shall deliver
any objection to any Notice of Exercise Form within one (1) Trading 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 $        [120% of the public offering price of the
Units], subject to adjustment hereunder (the “Exercise Price”).

 

c) Cashless Exercise.
If at the time of exercise hereof there is no effective registration statement permitting the issuance of the Warrant Shares, or
the prospectus contained therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may be
exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled
to receive a certificate for the 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”;

 

(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.

 

d) Mechanics
of Exercise.

 

i. Delivery of
Certificates Upon Exercise.  Certificates for shares purchased hereunder shall be transmitted by the Company’s
transfer agent (the “Transfer Agent”) to the Holder or the Participant by crediting the account of the Holder’s
or the Participant’s prime broker with the Depository 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 Holder or the Participant or (B) this Warrant is being exercised
via cashless exercise, and otherwise by physical delivery to the address specified by the Holder or the Participant in the Notice
of Exercise by the date that is three (3) Trading Days after the latest of (A) the delivery to the Warrant Agent of the Notice
of Exercise by the Holder, or, in the case of a Participant, the proper delivery of the Notice of Exercise by the Participant in
accordance with the Depository’s procedures, (B) surrender of this Warrant and (C) payment of the aggregate
Exercise Price as set forth above (including by cashless exercise, if permitted) (such date, the “Warrant Share Delivery
Date”).   If an effective registration statement is not
available at the time a Notice of Exercise is delivered by a Holder or a Participant to the Warrant Agent, the
Warrant Agent shall require an opinion of counsel prior to delivery of the Warrant shares via DWAC. 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 Warrant Agent 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.
If the Warrant Agent fails for any reason to deliver to the Holder certificates evidencing 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 after such Warrant Share Delivery Date until such certificates are delivered or Holder
rescinds such exercise.

 

ii. Delivery
of New Warrants Upon Exercise.  If this Warrant shall have been exercised in part, the Warrant Agent shall,
upon surrender of this Warrant, deliver to the Holder a new Warrant, which may be in electronic form, 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 Warrant Agent fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates
representing 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 Certificates Upon Exercise.  In addition to any other rights available to
the Holder, if the Warrant Agent fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates
representing the Warrant Shares 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 Warrant Shares that would have been issued had the Company timely complied with its exercise
and delivery obligations hereunder.  For example, if the Holder purchases shares of Common Stock having a total purchase
price of $11,000 to cover a Buy-In with respect to an attempted exercise of this Warrant for Warrant Shares, and sells such shares
of Common Stock at an aggregate sale price of $10,000 in connection with the sell order giving rise to such purchase obligation,
under clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall
provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the
Company, evidence of the amount of such loss.  Nothing herein shall limit a Holder’s right to pursue any other
remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or
injunctive relief with respect to the Company’s failure to timely deliver certificates representing the Warrant Shares 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 certificates for 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 certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates 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 certificates for 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.

 

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.  A Holder shall not have the right to exercise any portion of this Warrant, and the Company
shall not be obligated to effect any exercise 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 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 the portion of this Warrant that 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
that this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) with respect
to the portion of this Warrant exercised as set forth in the Notice of Exercise, 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 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 not less than 61 days’ prior notice to the Warrant Agent, may increase
or decrease the Beneficial Ownership Limitation provisions of this Section 2(e).  Any such increase or decrease 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
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
or, in the case of a subdivision, combination or re-classification, immediately after the effective date thereof.

 

b) Subsequent
Equity Sales. If the Company or any Subsidiary thereof, as applicable, at any time while this Warrant is outstanding, shall
sell or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue (or announce any
offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents, at an effective
price per share less than the Exercise Price then in effect (such lower price, the “Base Share Price” and such
issuances collectively, a “Dilutive Issuance”) (it being understood and agreed that if the holder of the Common
Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions,
floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued
in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is less than
the Exercise Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date of the Dilutive
Issuance at such effective price), then simultaneously with the consummation of each Dilutive Issuance the Exercise Price applicable
to the then-unexercised portion of this Warrant shall be reduced and only reduced to equal the Base Share Price.  Such
adjustment shall be made whenever such Common Stock or Common Stock Equivalents are issued.  Notwithstanding the foregoing,
no adjustments shall be made, paid or issued under this Section 3(b) in respect of an Exempt Issuance.  The Company shall
notify the Holder, in writing, no later than the Trading Day following the issuance or deemed issuance of any Common Stock or Common
Stock Equivalents subject to this Section 3(b), indicating therein the applicable issuance price, or applicable reset price, exchange
price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”).  For
purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 3(b), upon the
occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Warrant Shares based upon the Base Share Price
regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Exercise.

 

    	 

    	 

    

 

For purposes of this Section 3(b), the
term “Exempt Issuance” shall mean the issuance of (a) shares of Common Stock, common stock equivalents, restricted
stock units or other Options to employees, consultants, officers or directors of the Company pursuant to any existing or future
stock option, restricted stock, stock purchase or other equity compensation plan duly adopted for such purpose, by a majority of
the members of the Board of Directors or a majority of the members of a committee of non-employee directors established for such
purpose, and the issuance of Common Stock in respect of such common stock equivalents, restricted stock units or other Options,
(b) securities (including Common Stock and common stock equivalents) issued or issuable upon the exercise, conversion or exchange
of securities issued and outstanding on the date hereof, including the Warrants, provided that such securities have not been amended
since the date hereof to increase the number of such securities or to decrease the exercise price, exchange price or conversion
price of such securities, (c) securities issued or issuable as payment of dividends or interest to any holders of Common Stock
or common stock equivalents, and (d) securities issued pursuant to acquisitions or strategic transactions approved by a majority
of the disinterested directors of the Company, provided that any such issuance shall only be to a Person (or to the equityholders
of a Person) that the Company’s Board of Directors determines in good faith is, itself or through its subsidiaries, an operating
company or an owner of an asset in a business synergistic with the business of the Company and shall provide to the Company additional
benefits in addition to the investment of funds, but shall not, for the purposes of this clause (d), include a transaction in which
the Company is issuing securities primarily for the purpose of raising capital or to an entity whose primary business is investing
in securities.

 

c) Subsequent
Rights Offerings.  In addition to any adjustments pursuant to the other subsections of this Section 3, 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.  If
the Company, at any time while this Warrant is outstanding, shall distribute to all holders of Common Stock (and not to the Holder)
evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase
any security other than the Common Stock (which shall be subject to Section 3(b)), then in each such case the Exercise Price shall
be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution by a fraction of which the denominator shall be the VWAP determined as of the record date
mentioned above, and of which the numerator shall be such VWAP on such record date less the then per share fair market value at
such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of
the Common Stock as determined by the Board of Directors in good faith.  In either case the adjustments shall be described
in a statement provided to the Holder of the portion of assets or evidences of indebtedness so distributed or such subscription
rights applicable to one share of Common Stock.  Such adjustment shall be made whenever any such distribution is made
and shall become effective immediately after the record date mentioned above.

  

    	 

    	 

    

 

e) Fundamental
Transaction. If, at any time while this 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, including, but not
limited to, the Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market, 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 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 number of 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 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 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 Warrant Agent shall,
upon notice from the Company to the Warrant Agent, promptly mail to the Holder a notice setting forth the Exercise Price after such adjustment 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 mailed to the Holder at its last 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 (z) 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 mail such notice or any defect therein or in the mailing thereof shall not affect the validity
of the corporate action required to be specified in such notice.  To the extent that any notice provided hereunder constitutes,
or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously
file such notice with the Commission pursuant to a Current Report on Form 8-K.  The Holder shall remain entitled to 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.  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 Warrant Agent 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 and the Warrant Agent 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.  The
Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without
having a new Warrant issued.

 

b) New Warrants.
This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Warrant Agent,
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 the Warrant Agent 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 initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of Warrant
Shares issuable pursuant thereto.

 

c) Warrant Register.
The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of the original issuance
and the registration of transfer of this Warrant. The Company and the Warrant Agent may deem and treat the registered Holder of
this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all
other purposes, absent actual notice to the contrary.

 

Section 5.            The
Company’s Option to Redeem.

 

(a)           If
a registration statement is effective for the Warrant Shares under the 1933 Act, and if the closing price of the Common Stock on
the Trading Market is $ [200% of the Exercise Price] or more for 30 consecutive Trading Days, then this Warrant will be
subject to redemption at the option of the Company.  If the Warrant is subject to redemption, as set forth herein, the
Company may redeem the Warrant at any time at a price calculated by multiplying $0.000001 by the number of Warrant Shares into
which the Warrant is exercisable (the “Redemption Amount”).

 

    	 

    	 

    

 

(b)           Upon notice from the Company to the Warrant Agent, the Warrant Agent shall deliver to the Holder a written Notice of Redemption (the “Notice of Redemption”) specifying
the date for the redemption (the “Redemption Payment Date”), which date will not be less than 10 nor more than
30 days after the date of the Notice of Redemption (the “Redemption Period”).  A Notice of Redemption
will not be effective with respect to any portion of this Warrant for which the Holder has previously delivered a Notice of Exercise
and paid to the Warrant Agent the entire Exercise Price of such exercise.  Upon receipt of the Notice of Redemption,
the Holder will have until 5:00PM (New York time) on the date before the Redemption Payment Date to exercise the Warrant in whole
or in part, pursuant to Section 2 of this Warrant.  For a Holder to effect such an exercise, the Warrant Agent must have
received this Warrant, with the Notice of Exercise attached hereto appropriately completed and duly endorsed, and payment of the
Exercise Price no later than 5:00PM (New York time) the date before the Redemption Payment Date.  The Holder’s
right to exercise the Warrant or any portion thereof called for redemption will terminate at 5:00PM (New York time) on the date
of the Redemption Payment Date, unless the Company subsequently fails to pay the applicable Redemption Amount.  Upon
the Redemption Payment Date, the Redemption Amount will be recalculated based on any Warrant Shares the Holder may have exercised
prior to the Redemption Payment Date pursuant to this Section 5(b).  On the Redemption Payment Date, the Redemption Amount,
as recalculated (if at all), will be paid in good funds to the Holder.

 

Section 6.                      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, including, without limitation, the right to receive dividends, or other distributions,
exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders
or the election of directors of the Company or any other matter prior to the exercise hereof in accordance with Section 2.

 

b) Loss, Theft,
Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company, Warrant Agent or Transfer Agent,
as applicable, 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, and upon surrender and cancellation of such
Warrant or stock certificate, if mutilated, the Warrant Agent or Transfer Agent, as applicable, 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 Trading Day, then, such action may be taken or such right may be exercised on the next
succeeding Trading 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 executing stock certificates to execute and issue the necessary certificates for the 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 as and to the
extent 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 laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the
State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the
State of Delaware.

 

f) 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.  Without
limiting any other provision of this Warrant, 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.

 

g) Notices.  Any
notice, request or other document required or permitted to be given or delivered to the Holder by the Company, or by the Warrant
Agent on behalf of the Company, shall be delivered to the Holder by a nationally recognized overnight courier service or by first
class mail, postage prepaid, at the address of the Holder as reflected on the books of the Warrant Agent.

 

h) 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.

 

i) 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.

 

j) 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.

 

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

 

l) 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.

 

m) 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.

 

(n) Warrant Agreement.
This Warrant is issued under and in accordance with the Warrant Agreement, dated as of July ●, 2014 (the “Warrant
Agreement”), between the Company and the Warrant Agent and is subject to the terms and provisions contained in the Warrant
Agreement, to all of which terms the provisions the holder of this Warrant and the Beneficial Owners of the Warrants represented
by this Warrant consent by acceptance hereof. Copies of the Warrant Agreement are on file and can be inspected at the above-mentioned
office of the Warrant Agent and at the office of the Company at 135 E. 57th St., 12th Floor, New York, New York 10022.

WARRANT AGREEMENT

 

This Warrant Agreement
(this “Agreement”), dated as of [___________], 2014, is by and between Microlin Bio, Inc., a Delaware corporation
(the “Company”), and VStock Transfer, LLC, with offices at 18 Lafayette Place, Woodmere, New York (the “Warrant
Agent”). Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Warrant
Certificate.

 

WHEREAS, the Company
is engaged in an initial public offering (the “Offering”) of units consisting of common stock of the Company,
par value $0.000001 per share (“Common Stock”), and warrants to purchase shares of Common Stock of the Company
(“Warrants”) and, in connection therewith, has determined to issue and deliver up to [____________] Warrants
to public investors in the Offering, and [___________] Warrants, bearing restrictive legends, in each case each such Warrant evidencing
the right of the holder thereof to purchase one share of Common Stock of the Company for $[____] per share, subject to adjustment
as described herein;

 

WHEREAS, the Company
has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1,
No. 333-193315 (the “Registration Statement”) and prospectus (the “Prospectus”), for the
registration, under the Securities Act of 1933, as amended (the “Securities Act”), of the units to be sold in
the Offering, the shares of Common Stock included in the units to be sold in the Offering, the Warrants included in the units to
be sold in the Offering, and the shares of Common Stock underlying the Warrants;

 

WHEREAS, the Company
desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance,
registration, transfer, exchange, redemption and exercise of the Warrants;

 

WHEREAS, the Company
desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the
respective rights, limitation of rights and immunities of the Company, the Warrant Agent and the holders of the Warrants (the “Holders”);
and

 

WHEREAS, all acts and
things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company, countersigned
by or on behalf of the Warrant Agent, as provided herein, and delivered by the Company in the manner and for the consideration
described in the Registration Statement, the underwriting agreement for the Offering and applicable warrant, valid, legal and binding
obligations of the Company, and to authorize the execution and delivery of this Agreement.

 

NOW, THEREFORE, in
consideration of the mutual agreements herein contained, the parties hereto agree as follows:

 

1.          Appointment
of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant
Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this
Agreement.

 

    	 

    	 

    

 

2.          Warrants.

 

2.1           Form
of Warrant. Each Warrant shall be (a) issued in registered form only, (b) in substantially the form of Exhibit A attached
hereto (the “Warrant Certificate”), the provisions of which are incorporated herein, (c) signed by, or bear
the facsimile signature of a duly authorized officer of the Company, and (d) signed by the Warrant Agent. In the event the person
whose facsimile signature has been placed upon any Warrant Certificate shall have ceased to serve in the capacity in which such
person signed the Warrant Certificate before such Warrant Certificate is issued, it may be issued with the same effect as if he
or she had not ceased to be such at the date of issuance. All of the Warrants shall initially be represented by one or more book-entry
certificates (each, a “Book-Entry Warrant Certificate”).

 

2.2           Effect
of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid
and of no effect and may not be exercised by the holder thereof.

 

2.3           Registration.

 

2.3.1           Warrant
Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of the original
issuance and the registration of transfers of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall
issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance
with instructions delivered to the Warrant Agent by the Company. Except as provided in this Section 2.3.1, all of the Warrants
shall initially be represented by one or more Book-Entry Warrant Certificates deposited with the Depository Trust Company (the
“Depository”) and registered in the name of Cede & Co., a nominee of the Depository. Ownership of beneficial
interests in the Book-Entry Warrant Certificates shall be shown on, and the transfer of such ownership shall be effected through,
records maintained (i) by the Depository or its nominee for each Book-Entry Warrant Certificate; (ii) by institutions that have
accounts with the Depository (such institution, with respect to a Warrant in its account, a “Participant”);
or (iii) directly on the book-entry records of the Warrant Agent with respect only to owners of beneficial interests that represent
such direct registration.

 

If the Depository subsequently
ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding
making other arrangements for book-entry settlement within ten (10) days after the Depository ceases to make its book-entry settlement
available. In the event that the Company does not make alternative arrangements for book-entry settlement within ten (10) days,
or the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant
Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant
Certificate, and the Company shall instruct the Warrant Agent to deliver to the Depository definitive Warrant Certificates in physical
form evidencing such Warrants.

 

    	2

    	 

    

 

At the request of any
initial purchaser of Warrants, the Warrant Agent shall deliver to such purchaser definitive Warrant Certificates in physical form,
registered in the name of such purchaser, evidencing the Warrants purchased by such initial purchaser.

 

All definitive Warrant
Certificates shall be in substantially the form of Exhibit A attached hereto.

 

2.3.2           Beneficial
Owner; Registered Holder. The term “Beneficial Owner” shall mean any person in whose name ownership of a
beneficial interest in the Warrants evidenced by a Book-Entry Warrant Certificate is recorded in the records maintained by the
Depository or its nominee. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent
may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (the “Registered
Holder”), as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation
of ownership or other writing on the Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose
of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice
to the contrary. Any reference herein to the term Holder or Registered Holder shall include a Beneficial Owner who has received
definitive Warrant Certificates registered in its name.

 

3.          Terms
and Exercise of Warrants.

 

3.1           Warrant
Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions
of such Warrant Certificate and of this Agreement, to purchase from the Company the number of shares of Common Stock and at the
price of $[_____] per share, subject to the adjustments provided therein. The term “Warrant Price” as used in
this Agreement shall mean the price per share at which shares of Common Stock may be purchased at the time a Warrant is exercised.

 

3.2           Duration of Warrants. A Warrant may be exercised only during the period
(the “Exercise Period”) commencing on the date of issuance thereof and on or before the Termination Date. For
purposes of this Agreement, the “Termination Date” shall have the meaning set forth in the Warrant. Each Warrant
not exercised on or before the Termination Date shall become void, and all rights thereunder and all rights in respect thereof
under this Agreement shall cease at the close of business on the Termination Date. 

 

    	3

    	 

    

 

3.3           Exercise
of Warrants.

 

3.3.1           Payment.
Subject to the provisions of the Warrant and this Agreement, a Warrant, when countersigned by the Warrant Agent, may
be exercised by the Registered Holder thereof at any time or times on or after the Initial Exercise Date and on or before
the Termination Date by delivery to the Warrant Agent, at the office of the Warrant Agent, or at the office of its successor
as Warrant Agent, of a duly executed facsimile copy of the Notice of Exercise Form annexed to the Warrant Certificate and surrender of the Warrant
Certificate by the Holder or, in the case of a Book-Entry Warrant Certificate, a copy of the Notice
of Exercise Form annexed to the Warrant Certificate properly delivered by the Participant in accordance with the
Depository’s procedures, and (ii) within three (3) Trading Days following the date of exercise, payment in full of the
Warrant Price for each full share of Common Stock as to which the Warrant is exercised and any and all applicable taxes
(except as set forth below) due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of
Common Stock, and the issuance of such shares of Common Stock, by wire transfer or cashier’s check drawn on a United
States bank, made payable to the Company, unless the cashless exercise procedure specified in Section 2(c) of the Warrant Certificate is specified in the
applicable Notice of Exercise. When permitted by the provisions of the Warrant Certificate, the Registered Holder of any
Warrant may pay the Warrant Price by the cancellation of such number of Warrant shares as is necessary, in accordance with
the formula set forth in subsection 2(c) of the Warrant Certificate, to exercise the Warrant with respect to the maximum
number of Warrant shares purchasable pursuant to the cashless exercise procedure set forth in subsection 2(c) of the Warrant
Certificate. Partial exercises of the Warrant resulting in purchases of a portion of the total number of Warrant shares available
thereunder shall have the effect of lowering the outstanding number of Warrant shares purchasable thereunder in an amount
equal to the applicable number of Warrant shares purchased. The Holder and the Warrant Agent shall maintain records showing
the number of Warrant shares purchased and the date of such purchases and, in the case of a Book-Entry Warrant Certificate,
the Warrant Agent shall maintain records showing the notation that shall be made to the records maintained by the Depository,
its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance, if any, of the
Warrants remaining after an exercise of Warrants. The Warrant Agent shall, by the next Trading Day
following the date of exercise of any Warrant, advise the Company and the Transfer Agent and registrar in respect of (a) the
Warrant shares issuable upon such exercise as to the number of Warrants exercised in accordance with the terms and conditions
of this Agreement, (b) the instructions of each Registered Holder or Participant, as the case may be, with respect to
delivery of the Warrant shares issuable upon such exercise, and the delivery of definitive Warrant Certificates, as
appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise, (c) in case of a Book-Entry
Warrant Certificate, the notation that shall be made to the records maintained by the Depository, its nominee for each
Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance, if any, of the Warrants remaining
after such exercise and (d) such other information as the Company or such transfer agent and registrar shall reasonably
require. The Warrant Agent shall deliver any objection to any Notice of Exercise Form within one (1) Trading Day of receipt
of such notice. The Holder and any assignee, by acceptance of the applicable Warrant, acknowledge and agree that, by reason
of the provisions of this paragraph, following the purchase of a portion of the Warrant shares thereunder, the number of
Warrant shares available for purchase thereunder at any given time may be less than the amount stated on the face
thereof.

 

    	4

    	 

    

 

3.3.2           Issuance
of Common Stock. Certificates for shares of Common Stock purchased pursuant to the exercise of any Warrant shall
be transmitted by the Company’s transfer agent (the “Transfer Agent”) to the Holder or the
Participant by crediting the account of the Holder’s or the Participant’s prime broker 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 Holder or the Participant or (B) the Warrant is being exercised via cashless exercise, and otherwise
by physical delivery to the address specified by the Holder or the Participant in the Notice of Exercise by the date that is
three (3) Trading Days after the latest of (A) the delivery to the Warrant Agent of the Notice of Exercise by the Holder or,
in the case of a Participant, the proper delivery of the Notice of Exercise by the Participant in accordance with the
Depository’s procedures, (B) surrender of the Warrant Certificate and (C) payment of the aggregate Exercise Price as
set forth above and in the Warrant Certificate (including by cashless exercise, if permitted) (such date, the
“Warrant Share Delivery Date”). It is hereby understood that if an effective registration
statement is not available at the time a Notice of Exercise is delivered by
a Holder or a Participant to the Warrant Agent, the Warrant Agent shall require an opinion of
counsel prior to delivery of the Warrant shares via DWAC. 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. If the Company fails for any reason to deliver to the Holder certificates
evidencing 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 after such
Warrant Share Delivery Date until such certificates are delivered or Holder rescinds such exercise. If the Warrants are not
delivered by the Warrant Share Delivery Date, the Warrant Agent shall immediately notify the Company of the untimely
delivery, the Warrant Share Delivery Date and the date of the delivery of the Warrant shares to facilitate the
Company’s payment of any damages associated therewith. For purposes of this Section 3.3.2, the certificates evidencing
the Warrant shares subject to a Notice of Exercise shall include delivery through book-entry records.

 

3.3.3           Delivery
of New Warrants Upon Exercise. If the Warrant shall have been exercised in part, the Warrant Agent shall, upon surrender
of the Warrant Certificate, deliver to the Holder a new Warrant Certificate, which may be in electronic form, evidencing the
rights of the Holder to purchase the unpurchased Warrant shares called for by the Warrant, which new Warrant shall in
all other respects be identical with the surrendered Warrant.

 

3.3.4           Rescission
Rights.  If the Transfer Agent does not transmit to the Holder a certificate or the certificates representing the
Warrant shares pursuant to Section 2(d)(i) of the Warrant Certificate by the Warrant Share Delivery Date, then the Holder will
have the right to rescind such exercise.

 

3.3.5           Charges,
Taxes and Expenses. Issuance of certificates for 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 certificate, all of which taxes and expenses shall
be paid by the Company, and such certificates 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 certificates for Warrant shares are to be issued in a name other than
the name of the Holder, the Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached to the Warrant
Certificate 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.

3.3.6           Valid Issuance. All shares of Common Stock issued upon the proper exercise
or surrender of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

 

3.3.7           Date
of Issuance. Each person or entity in whose name any such certificate for shares of Common Stock is issued shall, for all purposes,
be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the
Warrant Price was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and
payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder
of such shares at the close of business on the next succeeding date on which the stock transfer books are open. The Company will
not close its stockholder books or records in any manner which prevents the timely exercise of the Warrants, pursuant to the terms
thereof.

 

3.3.8           Holder’s
Exercise Limitations. A Holder shall not have the right to exercise any portion of the Warrant, and neither the Warrant Agent
nor the Company shall be obligated to effect any exercise of the Warrant 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. For purposes of the foregoing sentence, the number of shares of Common Stock beneficially
owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise of the 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 the 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 Equivalent) 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, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934,
as amended (the “Exchange Act”), and the rules and regulations promulgated thereunder, it being acknowledged
by the Holder that neither the Warrant Agent nor the Company is 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 applies, the determination of whether the Warrant is exercisable
(in relation to other securities owned by the Holder together with any Affiliates) and of the portion of the Warrant that 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 that the Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates)
with respect to the portion of the Warrant exercised as set forth in the Notice of Exercise, in each case subject to the Beneficial
Ownership Limitation, and neither the Warrant Agent nor the Company shall have any 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, 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
the 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 the Warrant. The Holder, upon not less
than 61 days’ prior notice to the Warrant Agent, may increase or decrease the Beneficial Ownership Limitation provisions
of this section. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Warrant
Agent and 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 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 the Warrant.

4.          Adjustments.

 

4.1           Notices
of Changes in Warrant. Potential adjustments are set forth in the Warrant Certificate. Upon every adjustment of
the Warrant Price or the number of shares issuable upon exercise of a Warrant, the Company shall give written notice thereof
to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease,
if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail
the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any such adjustment, and
upon notice from the Company to the Warrant Agent, the Warrant Agent shall give written notice to each Warrant holder, at
the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event
and setting forth a brief statement of facts requiring such adjustment. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such event.

 

4.2           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 mailed to the Holder at its last
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 (z) 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 mail such notice or any defect therein or in the mailing
thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice
provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries,
the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder shall
remain entitled to exercise the Warrants 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.

 

    	7

    	 

    

 

4.3           No
Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, no fractional shares or scrip
representing fractional shares shall be issued upon the exercise of the Warrants.  As to any fraction of a share which
the Holder would otherwise be entitled to purchase upon such exercise, the Warrant Agent shall, at the Company’s election,
either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Warrant Price
or round up to the next whole share.

 

4.4           Form of Warrant. The form of Warrant need not be changed because of any
adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same
number of shares as is stated in the Warrants initially issued pursuant to this Agreement. However, the Company may, at any time,
in its sole discretion, make any change in the form of Warrant that the Company may deem appropriate and that does not affect the
substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant
or otherwise, may be in the form as so changed.

 

4.5           Calculations.
All calculations under Section 3 of the Warrant Certificate shall be made to the nearest cent or the nearest 1/100th of a share,
as the case may be. For purposes of that section, 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.

 

    	8

    	 

    

 

5.          Transfer
and Exchange of Warrants.

 

5.1           Registration
of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant into the Warrant
Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly
guaranteed, at the principal office of the Warrant Agent or its designated agent, together
with a written assignment of the Warrant substantially in the form attached thereto 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, a new Warrant or Warrants in the name of the assignee or assignees, as applicable, representing an equal aggregate
number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall
be delivered by the Warrant Agent to the Company from time to time upon the Company’s request.

 

5.2           Procedure
for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or
transfer, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered
Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except
as otherwise provided herein or in any Book-Entry Warrant Certificate, each Book-Entry Warrant Certificate may be transferred only
in whole and only to the Depository, to another nominee of the Depository, to a successor depository, or to a nominee of a successor
depository; provided further, however, that, in the event a Warrant surrendered for transfer bears a restrictive legend,
the Warrant Agent shall not cancel such Warrant and shall issue new Warrants in exchange therefor until the Warrant Agent has received
an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also
bear a restrictive legend.

 

5.3           Fractional
Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the
issuance of a warrant certificate for a fraction of a warrant.

 

5.4           Warrant
Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever
required by the Warrant Agent, will supply the Warrant Agent with Warrant Certificates duly executed on behalf of the Company for
such purpose.

 

6.          Other
Provisions Relating to Rights of Holders of Warrants.

 

6.1           No
Rights as Stockholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a stockholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights
to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors
of the Company or any other matter.

 

6.2           Lost,
Stolen Mutilated or Destroyed Warrants. The Company covenants that upon receipt by the Company, Warrant Agent or Transfer Agent,
as applicable, of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of the 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, and upon surrender and cancellation of such
Warrant or stock certificate, if mutilated, the Warrant Agent or Transfer Agent, as applicable, 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.

 

    	9

    	 

    

 

6.3           Reservation
of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of
Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

 

7.          Concerning
the Warrant Agent and Other Matters.

 

7.1           Payment
of Taxes. Subject to Section 3.3.5 hereof, the Company will, from time to time, promptly pay all taxes and charges that may
be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise
of Warrants.

 

7.2           Resignation,
Consolidation, or Merger of Warrant Agent.

 

7.2.1           Appointment
of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged
from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the
office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint, in writing,
a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of
thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder
of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of
any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor
Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation in good standing
in the State of New York, with its principal office in the Borough of Manhattan, City and State of New York, and authorized under
such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authorities. After appointment,
any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties and obligations of its predecessor
Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but, if for
any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the
Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant
Agent hereunder; and, upon request of any successor Warrant Agent, the Company shall make, execute, acknowledge, and deliver any
and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such
authority, powers, rights, immunities, duties and obligations.

 

7.2.2           Notice
of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof
to the predecessor Warrant Agent and the transfer agent for the Common Stock not later than the effective date of any such appointment.

 

7.2.3           Merger
or Consolidation of Warrant Agent. Any company into which the Warrant Agent may be merged or with which it may be consolidated
or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor
Warrant Agent under this Agreement without any further act on the part of the Company or the Warrant Agent.

7.3           Fees
and Expenses of Warrant Agent.

 

7.3.1           Remuneration.

forth on Exhibit B hereto and shall reimburse the Warrant Agent
upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

 

7.3.2           Further
Assurances. The Company and the Warrant Agent agree to perform, execute, acknowledge and deliver, or cause to be performed,
executed, acknowledged and delivered, all such further and other acts, instruments and assurances as may reasonably be required
by the Warrant Agent or the Company for the carrying out or performing of the provisions of this Agreement.

 

7.4           Liability
of Warrant Agent.

 

7.4.1           Reliance
on Company Statement. Whenever, in the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary
or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder,
such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer or Chairman of the Board of
the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered
in good faith by it pursuant to the provisions of this Agreement.

 

7.4.2           Indemnity.
The Warrant Agent shall be liable hereunder only for its own negligence, willful misconduct or bad faith. The Company agrees to
indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel
fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s
negligence, willful misconduct or bad faith.

 

7.4.3           Exclusions. The Warrant Agent shall have no responsibility with respect
to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof);
nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant
Certificate; nor shall it be responsible to make any adjustments required under the provisions of the Warrant Certificate or responsible
for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such
adjustment; nor shall it, by any act hereunder, be deemed to make any representation or warranty as to the authorization or reservation
of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock
will when issued be validly issued and fully paid and nonassessable.

 

7.5           Acceptance
of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the
terms and conditions herein set forth and, among other things, shall account promptly to the Company with respect to Warrants exercised
and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of shares of the
Company’s Common Stock through the exercise of the Warrants.

in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United States District

8.7.1           This
Agreement may be amended by the parties hereto, without the consent of any of the Holders, for the purpose of (i) curing any ambiguity,

8.7.2           In
the event that Section 8.7.1 does not apply, the Company and the Warrant Agent may amend this Agreement and the Warrant Certificates
by executing a Supplemental Agreement with the consent of the Holders of not fewer than a majority of the unexercised Warrants
affected by such amendment, for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions
of this Agreement or of modifying in any manner the rights of the Holders under this Agreement; provided, however, that,
without the consent of each of the Warrant holders affected thereby, no such amendment may be made that (i) changes the Warrants

pursuant to the adjustment provisions set forth in the Warrant Certificate), (ii) shortens the period of time during which the
