B.           Battery,

the Investors, to the Original 2013 Securities Purchase Agreement pursuant to Section 6.12 of the Original 2013 Securities Purchase
Agreement.

 

C.           The
Company, Battery, PAR, Ackerman and Morris wish to amend and restate the Original 2013 Securities Purchase Agreement, including

In consideration of the mutual

the Company and each Investor hereby agree as follows:

 

1.          Purchase
and Sale of Shares and Warrants.

of the conditions to the Closing set forth in Section 5 thereof. At the Closing, the Escrow Agent (i) released the aggregate Purchase
Price to the Company, (ii) delivered the Warrants to the Investors and (iii) delivered the Transfer Agent Instruction Letter to
the Company’s transfer agent.

 

    	 

    	 

    

 

1.2.          Exercise
of Investor Put Option.

 

(a)          Subject
to adjustments pursuant to Section 1.2(b), if any, upon the occurrence of a Put Option Trigger Event (as defined below), each Investor
shall have the right to elect to require the Company to acquire, severally and not jointly, from such Investor the Shares held
by such Investor (the “Put Shares”) for an amount equal to the number of Put Shares times the Per Share Price
(the “Put Right”). An Investor may exercise their Put Right by delivering written notice to the Company (the
“Put Option Exercise Notice”) within thirty (30) days of a Put Option Trigger Event (the “Put Option
Exercise Deadline”), which shall indicate (x) the total number of Put Shares to be acquired from the exercising Investor
and (y) the Business Day on which the closing of the purchase of the Put Shares subject to the Put Option Exercise Notice shall
occur (the “Put Option Closing”); provided, however, that the Put Option Closing shall occur at least
five (5) Business Days following the Put Option Exercise Deadline and no later than ninety (90) Business Days following the Put
Option Exercise Deadline.

 

(b)          Adjusted
Put Shares. In the event that the Company does not have sufficient Legally Available Cash (as defined below) to satisfy all
of its put right obligations in this Agreement and the Other Securities Purchase Agreements, the Put Right for an Investor shall
be limited to a number of Put Shares (“Adjusted Put Shares”) equal to the following (rounded to the nearest
whole number):

 

APS = [(X * [(A*Y)/((A*Y)+(B*Z)+(C*W))]]
/ Y

 

APS = Adjusted Put Shares

 

X = Legally Available Cash

 

A = total number of Put Shares that an Investor elects to
have repurchased pursuant to such Investor’s Put Right in connection with the relevant Put Option Triggering Event

 

B = total number of put shares that 2011 Investors elect
to have repurchased pursuant to such investors’ put rights in the Amended and Restated 2011 Purchase Agreement in connection
with the relevant Put Option Triggering Event

 

C = total number of put shares that 2015 Investors elect

2011 Purchase Agreement)

“Legally Available
Cash” means the maximum of amount of cash that the Company is legally permitted (as determined by an opinion of counsel)
to spend on the repurchase of shares of Common Stock from the Investors, the 2011 Investors and/or the 2015 Investors, whether
or not such maximum amount of cash is then actually available to the Company.  If there are no legal restrictions on the repurchase
of Common Stock held by the Investors, the 2011 Investors and/or the 2015 Investors, then “Legally Available Cash”
shall be deemed to be in excess of the amount necessary to satisfy all of the Company’s put right obligations under this
Agreement and the Other Securities Purchase Agreements, and as such this clause (b) shall not apply.

 

(c)          The
Put Right shall terminate for all Investors if one of the following events has occurred:

 

(i)          the
daily VWAP of the Common Stock is greater than or equal to three hundred and seventy-five percent (375%) of the Per Share Price
for any consecutive forty trading-day period (the “Measurement Period”) and (y) the daily volume traded in Common
Stock has averaged at least 250,000 shares during such Measurement Period, provided that such daily volume shall be adjusted proportionately
to account for any stock splits or reverse stock splits of the Common Stock;

 

(ii)         (x)
the Company completes an offering of its Common Stock registered under the Securities Act with gross proceeds to the Company of
at least fifteen million dollars ($15,000,000) at a price per share that equals or exceeds three hundred and seventy-five percent
(375%) of the Per Share Price and (y) the resale of the Shares held by the Investors at such time is registered on an effective
registration statement under the Securities Act;

 

(iii)        a
sale by one of the Investors of twenty-five percent (25%) of the Shares held by such Investor, provided, however, that a
sale by such Investor will only affect such Investor and will not affect the Put Right of any other Investor;

 

(iv)        each
of Battery (unless Battery’s Put Right has terminated), PAR (unless PAR’s Put Right has terminated) and the Company
consent in writing to terminate the Put Right; or

 

(v)         if
Battery’s and PAR’s Put Right have terminated, the Investors, other than Battery and PAR, holding a majority of the
Shares held by all such non-Battery and non-PAR Investors and the Company consent in writing to terminate the Put Right.

 

(d)          Battery’s
Put Right shall terminate if both Battery and the Company consent in writing to terminate Battery’s Put Right.

any provision of any instrument or contract to which it is a party or by which it or any of its Property is bound, or in violation
of any provision of any Governmental Requirement applicable to it, except for any violation or default under any such instrument
or contract or any violation of any provision of a Governmental Requirement that, in either such case, has not had or would not

is unconditional (other than with respect to the conditions set forth in the Warrants) regardless of the effect of any such dilution.

Intellectual Property necessary for the conduct of its business as presently conducted (other than with respect to software which

by any other Person of any material rights of the Company under any Intellectual Property Rights.

 

(d)          All
licenses or other agreements under which the Company is granted Intellectual Property (excluding licenses to use software utilized
in the Company’s internal operations and which is generally commercially available) are in full force and effect and, to
the Company’s knowledge, there is no material default by any party thereto. The Company has no reason to believe that the

Property of any other Person, including, without limitation, any former employer of any past or present employees of the Company.

of such employees relating to any Intellectual Property of such employers, which materially interfere or conflict with the performance
of such employee’s duties for the Company or result in any former employers of such employees having any rights in, or claims
on, the Company’s Intellectual Property. Each current employee of the Company and each former employee of the Company who
was hired after January 1, 2011 has executed agreements regarding confidentiality, proprietary information and assignment of inventions
and copyrights to the Company, each independent contractor or consultant of the Company has executed agreements regarding confidentiality
and proprietary information, and the Company has not received written notice that any employee, consultant or independent contractor

to guard against unauthorized disclosure or use of any of its Intellectual Property; and (ii)

access to any of its Intellectual Property. The Company is in compliance in all material respects with its obligations pursuant
to all agreements relating to Intellectual Property rights that are the subject of licenses granted by third parties, except for

any fact or circumstance (including without limitation (i) the terms of any agreement to which such person is a party or any litigation
in which such person is or may become involved and (ii) any illness or medical condition that could reasonably be expected to result

set forth in the Transaction Documents.

keep and preserve all of its Properties necessary in the proper conduct of its businesses in good repair, working order and condition

    	22

    	 

    

 

(f)          pay

each of the Company’s Chief Executive Officer and President (each, a “Specified Employee”) from selling
shares of Common Stock; and

 

(l)          use
commercially reasonable efforts to maintain adequate insurance coverage (including D&O insurance) for the Company and each

4.2.          Voting
Rights.

 

(a)          The
Company agrees that it shall not approve of or give effect to any of the actions listed below (by amendment, merger, consolidation
or otherwise) without the written consent of Battery and PAR. Notwithstanding the foregoing: (1) in the event that Battery meets
the Threshold Amount, Battery’s consent is not required pursuant to this Section 4.2(a), however, PAR’s consent is
still required; and (2) in the event that PAR meets the Threshold Amount, PAR’s consent is not required pursuant to this
Section 4.2(a), however Battery’s consent is still required.

 

(i)          alter
or change the rights, preferences or privileges of the Put Option; or

 

(ii)         liquidate,
dissolve or wind-up the business and affairs of the Company or consent to any of the foregoing; and

 

    	23

    	 

    

 

(b)          The
Company agrees that it shall not approve of or give effect to any of the actions listed below (by amendment, merger, consolidation
or otherwise) without the written consent of Battery and either PAR or Harris & Harris. Notwithstanding the foregoing: (1)
in the event that Battery meets the Threshold Amount, Battery’s consent is not required pursuant to this Section 4.2(b),
however the consent of either PAR or Harris & Harris is still required; (2) in the event that PAR meets the Threshold Amount,
PAR’s consent is not required pursuant to this Section 4.2(b), however the consent of Battery and Harris & Harris is
still required; and (3) in the event that Harris & Harris has sold equal to or greater than twenty-five percent (25%) of the
Shares it purchases on the Closing Date, the consent of Harris & Harris is not required pursuant to this Section 4.2(b), however
the consent of Battery and PAR is still required.

 

(i)          purchase,
redeem or otherwise acquire any of (A) the Company’s equity securities (including warrants, options and other rights to acquire
equity securities) or (B) the Securities, other than (1) a repurchase by the Company at the lower of cost or the fair market value
pursuant to existing agreements, (2) the purchase of capital stock from certain stockholders approved by each of the Investors,
(3) pursuant to an exercise of the Put Right or the put rights granted under the Other Securities Purchase Agreements or (4) the
contemplated option exchange disclosed in the disclosure schedules to the 2015 Purchase Agreement;

 

(ii)         merge
or consolidate with another corporation or entity in which the holders of the Company’s voting equity securities immediately
prior to the transaction own, directly or indirectly, fifty percent (50%) or less of the voting securities of the surviving corporation
unless (A) the consideration for the merger or consolidation is in the form of a cash offer or marketable securities that are registered,
saleable and listed on the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market or the New York Stock

4.3.          Board
Representation. The Company shall be obligated to present one nominee nominated by each of Battery (the “Battery Member”)
and PAR (the “PAR Member”) to become a member of the Company’s Board for election by the Company’s
stockholders; provided, however, that the Company shall no longer be obligated to nominate the Battery Member in the event
that Battery has sold or no longer holds the Threshold Amount with respect to Battery and the Company shall no longer be obligated
to nominate the PAR Member in the event that PAR has sold or no longer holds the Threshold Amount with respect to PAR. Battery’s
right to nominate the Battery Member for election to the Company’s Board above is cumulative with its existing right to nominate
a person for election to the Company’s Board pursuant to the Amended and Restated 2011 Purchase Agreement; e.g., Battery
shall have a right to nominate only one person for election to the Company’s Board. Upon the election of each of the Battery
Member and the PAR Member to the Company’s Board, the Company shall execute an indemnification agreement with the Battery
Member and the PAR Member, in a form satisfactory to Battery and PAR, as applicable and shall include the Battery Member and the
PAR Member on the Company’s director and officer insurance policy.

 

    	24

    	 

    

 

4.4.          No
Participation Rights. Each Investor who had participation rights pursuant to the Original 2013 Securities Purchase Agreement
has declined to exercise such Investor’s participation right set forth in such Original 2013 Securities Purchase Agreement
with respect to either the Company’s issuance of convertible promissory notes on December 1, 2014 or the transaction contemplated
by the 2015 Purchase Agreement and thus no longer has any participation right with respect to either the transaction contemplated
by the 2015 Purchase Agreement or future financings of the Company.

 

4.5.          Reservation
of Common Stock. The Company shall, on the Closing Date, have authorized and reserved for issuance to the Investors free from
any preemptive rights, and shall keep available at all times during which any Warrants are outstanding, a number of shares of Common
Stock (the “Reserved Amount”) that, on the Closing Date, is not less than one hundred
percent (100%) of the number of Warrant Shares issuable upon exercise of all of the Warrants issued at the Closing, without regard
to any limitation or restriction on such conversion or exercise that may be set forth in the Warrants. The Reserved Amount shall
be allocated in accordance with each Investor’s Pro Rata Share. In the event that an Investor shall sell or otherwise transfer
any of such Investor’s Warrants, each transferee shall be allocated a pro rata portion of such transferor’s
Reserved Amount. Any portion of the Reserved Amount allocated to any Investor or other Person which no longer holds any Warrants
shall be reallocated to the remaining Investors pro rata based on the number of 2013 Registrable Securities held by such
Investors at such time. In the event that the Reserved Amount is insufficient at any time to cover one hundred percent 100% of
the 2013 Registrable Securities issuable upon the exercise of the Warrants (without regard to any restriction on such conversion
or exercise), the Company shall take such action (including without limitation holding a meeting of its stockholders) to increase
the Reserved Amount to cover 100% of the 2013 Registrable Securities issuable upon such conversion and exercise, such increase
to be effective not later than the thirtieth (30th) day (or sixtieth (60th) day, in the event stockholder approval is required
for such increase) following the Company’s receipt of written notice of such deficiency. While any Warrants are outstanding,
the Company shall not reduce the Reserved Amount without obtaining the prior written consent of each Investor then holding Warrants.

 

4.6.          Use
of Proceeds. The Company shall use the proceeds from the sale of the Shares and Warrants for general business purposes; provided,
that the Company shall not use any of such proceeds (i) to pay any dividend or make any distribution on any of its securities,
or (ii) to repay any loan made to or incurred by any Key Employee or any other officer or director or Affiliate of the Company.

 

4.7.          Use
of Investor Name. Except as may be required by applicable law and/or this Agreement, the Company shall not use, directly or
indirectly, any Investor’s name or the name of any of its Affiliates in any advertisement, announcement, press release or
other similar communication unless it has received the prior written consent of any Investor for the specific use contemplated
or as otherwise required by applicable law or regulation.

 

4.8.          Company’s
Instructions to Transfer Agent. The Company shall cause its transfer agent to remove the restrictive legend set forth in Section
2.5 from certificates evidencing the Shares and Warrant Shares (i) in connection with any sale of such Shares or Warrant Shares
pursuant to a registration statement (including a Registration Statement) covering the resale of such security that is effective
under the Securities Act, (ii) in connection with any sale of such Shares or Warrant Shares pursuant to Rule 144, or (iii) if such
legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements
issued by the staff of the Commission), as set forth below. If all or any part of a Warrant is exercised in connection with an
immediate resale of the exercised Warrant Shares pursuant to an effective registration statement, or in connection with an immediate
resale of the exercised Warrant Shares pursuant to Rule 144, the Company shall cause its transfer agent to remove the restrictive
legend from certificates issued representing the exercised Warrant Shares, as set forth below.

 

    	25

    	 

    

 

(a)          The
Company shall issue an instruction letter to its transfer agent to remove the restrictive legend in connection with any sale of
the Shares or Warrant Shares pursuant to a registration statement, and shall cause its counsel, if required by the transfer agent,
to issue a legal opinion authorizing the removal of restrictive legend in connection with a sale of the Shares or Warrant Shares
pursuant Rule 144, provided that the relevant Investor shall have delivered to the Company, its counsel and its transfer agent
a certification of such facts as the Company and its counsel may reasonably require in connection with providing such instruction
letter or legal opinion.

 

(b)          The
Company shall instruct its transfer agent to remove the restrictive legend as permitted by this Section 4.8 promptly after delivery
by the Investor to the Company or its transfer agent of the certificate representing the Shares or Warrant Shares being sold by
the Investor.

 

(c)          The
Company may not make any notation on its records or give instructions to its transfer agent that enlarge the restrictions on transfer
set forth in this Section 4.8.

 

(d)          Certificates
for Shares or Warrant Shares subject to legend removal hereunder shall be transmitted by the Company’s transfer agent to
the purchaser of such Shares or Warrant Shares by crediting the account of such purchaser’s prime broker with the Depository
Trust Company System, if so directed by the selling Investor.

 

4.9.          Limitations
on Disposition. No Investor shall sell, transfer, assign or dispose of any Securities, unless:

 

(a)          there
is then in effect an effective registration statement under the Securities Act covering such proposed disposition and such disposition
is made in accordance with such registration statement; or

 

(b)          such
Investor has notified the Company in writing of any such disposition, and furnished the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration of such Securities under the Securities Act; provided,
however, that no such opinion of counsel will be required (A) if the sale, transfer or assignment complies with federal and
state securities laws and is made to a fund or other institutional investor that is an Affiliate of such Investor and which is
also an “accredited investor” as that term is defined in Rule 501 of Regulation D; provided, that such Affiliate
provides the Company with customary accredited investor and investment representations (comparable with those set forth in Section
2.2 hereof), and agrees to be bound by the terms and conditions of this Agreement, (B) if the sale, transfer or assignment is made
pursuant to Rule 144 and such Investor has complied with the obligations set forth in Section 4.8(a) above or (C) in connection
with a bona fide pledge or hypothecation of any Securities under a margin arrangement with a broker-dealer or other financial
institution or the sale of any such Securities by such broker-dealer or other financial institution following such Investor’s
default under such margin arrangement.

 

    	26

    	 

    

 

4.10.         Disclosure
of Non-public Information. The Company agrees that it will not at any time following the Execution Date disclose material non-public
information to any Investor without first obtaining such Investor’s written consent to such disclosure, except to the extent
required by any Transaction Documents. For the avoidance of doubt, any information provided to the Battery Member or PAR Member
in its capacity as a member of the Board of Directors shall not be deemed a disclosure of information pursuant to this Section.

 

4.11.         Listing.
Provided the Company is eligible for trading or listing, as the case may be, the Company (i) has, or promptly following the Closing
shall, use its best efforts to include all of the Warrant Shares
issuable upon exercise of the Warrants (without regard to any limitation on such exercise) for trading on the OTCBB, and (ii) shall
use its best efforts to attain designation and quotation, or listing, of the Common Stock and Warrant Shares on the Nasdaq Capital
Market, the Nasdaq Global Market, the Nasdaq Global Select Market or the New York Stock Exchange for a minimum of five (5) years
following the Closing Date or, in the event the Company is unable to attain such designation and quotation or listing on the Nasdaq
Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market or the New York Stock Exchange, to maintain the trading
of the Common Stock on the OTCBB or any successor interdealer trading system for a minimum of five (5) years following the Closing
Date.

 

4.12.         Indemnification
of Investors. The Company will indemnify and hold each Investor and its directors, managers, officers, shareholders, members,
partners, employees and agents (each, an “Investor Party”) harmless from any and all losses, liabilities, obligations,
claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable
attorneys’ fees and costs of investigation that any such Investor Party may suffer or incur as a result of or relating to
(a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the
other Transaction Documents or (b) any action instituted against an Investor, or any of them or their respective Affiliates, by
any stockholder of the Company who is not an Affiliate of such Investor, with respect to any of the transactions contemplated by
the Transaction Documents (unless such action is based upon a breach of such Investor’s representations, warranties or covenants
under the Transaction Documents or any agreements or understandings such Investor may have with any such stockholder or any violations
by such Investor of state or federal securities laws or any conduct by such Investor which constitutes fraud, gross negligence,
willful misconduct or malfeasance). If any action shall be brought against any Investor Party in respect of which indemnity may
be sought pursuant to this Agreement, such Investor Party shall promptly notify the Company in writing, and the Company shall have
the right to assume the defense thereof with counsel of its own choosing. Any Investor Party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense
of such Investor Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in
writing, (ii) the Company has failed after a reasonable period of time following such Investor Party’s written request that
it do so, to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate
counsel, a material conflict on any material issue between the position of the Company and the position of such Investor Party.
The Company will not be liable to any Investor Party under this Agreement (i) for any settlement by an Investor Party effected
without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (ii) to the extent,
but only to the extent that a loss, claim, damage or liability is attributable to such Investor Party’s wrongful actions
or omissions, or gross negligence or to such Investor Party’s breach of any of the representations, warranties, covenants
or agreements made by such Investor in this Agreement or in the other Transaction Documents.

 

    	27

    	 

    

 

4.13.         Indemnification
of the Company. Each Investor, severally and not jointly and only to the extent of such Investor’s Purchase Price, will
indemnify and hold the Company and its directors, manager, officers, shareholders, employees and agents (each, a “Company
Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses,
including all judgments, amounts paid in settlements, court costs and reasonable
attorneys’ fees and costs of investigation that any such Company Party may suffer or incur as a result of or relating to
(a) any breach of any of the representations, warranties, covenants or agreements made by or on behalf of such Investor in this
Agreement or in the other Transaction Documents or (b) any violations by such Investor of state or federal securities laws or any
conduct by such Investor which constitutes fraud, gross negligence, willful misconduct or malfeasance. If any action shall be brought
against any Company Party in respect of which indemnity may be sought pursuant to this Agreement, such Company Party shall promptly
notify the Investor in writing, and the Investor shall have the right to assume the defense thereof with counsel of its own choosing.
Any Company Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such Company Party except to the extent that (i) the employment
thereof has been specifically authorized by such Investor in writing, (ii) the Investor has failed after a reasonable period of
time following such Company Party’s written request that it do so, to assume such defense and to employ counsel or (iii)
in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between
the position of such Investor and the position of such Company Party. Such Investor will not be liable to any Company Party under
this Agreement for any settlement by a Company Party effected without such Investor’s prior written consent, which shall
not be unreasonably withheld or delayed.

6.          Miscellaneous.

 

6.1.          Survival;
Severability. The representations, warranties, covenants and indemnities made by the parties herein and in the other Transaction
Documents shall survive the Closing notwithstanding any due diligence investigation made by or on behalf of the party seeking to
rely thereon. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to
be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided that
in such case the parties shall negotiate in good faith to replace such provision with a new provision which is not illegal, unenforceable
or void, as long as such new provision does not materially change the economic benefits of this Agreement to the parties.

 

6.2.          Successors
and Assigns. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective successors
and permitted assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other

or by reason of this Agreement, except as expressly provided in this Agreement. After the Closing, the Investors may assign their
respective rights and obligations hereunder, in connection with any private sale or transfer of the Shares or Warrants in accordance

to be bound by the applicable provisions of this Agreement, in which case the term “Investor” shall be deemed to refer
to such transferee as though such transferee were an original signatory hereto. The Company may not assign its rights or obligations
under this Agreement.

 

6.3.          No
Reliance. Each party acknowledges that (i) it has such knowledge in business and financial matters as to be fully capable of

AMENDMENT NO. 1 TO

2011 WARRANTS

TO PURCHASE COMMON STOCK OF

CHAMPIONS ONCOLOGY, INC.

 

This Amendment No. 1 (this “Amendment”)
to the Warrants with the issue date of April 4, 2011 (the “Original Warrants”), effective as of March 13, 2015,
is between Champions Oncology, Inc. (the “Company”) and the other parties hereto, who constitute the holders
of Original Warrants exercisable for a majority of the number of shares of Common Stock of the Company into which all of the Original
Warrants outstanding as of the date hereof are exercisable, and is thus binding upon all of the holders of Original Warrants pursuant
to Section 12 of the Original Warrants.

 

WHEREAS, the parties hereto wish to amend the
terms of the Original Warrants;

 

NOW, THEREFORE, in consideration of the foregoing
and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledge, the parties agree as follows.

 

1.          Section
5(c) of each of the Original Warrants is deleted in its entirety and replaced with “[Reserved]”.

 

2.          The
last sentence of Section 1(a) is amended and restated in its entirety as follows:

 

“The “Exercise Price” for each
Warrant Share purchased by the Holder upon the exercise of this Warrant shall be equal to $0.40, subject to adjustment for the
events specified in Section 5 below.”

 

For purposes of this Amendment, the definition of “Exercise
Price” in the Original Warrants (before giving effect to the amendment in this Section 2) is referred to as the “Original
Exercise Price”, and the definition of “Exercise Price” in the Original Warrants (after giving effect to
the amendment in this Section 2) is referred to as the “New Exercise Price”.

 

3.          The
number of shares issuable upon exercise of each of the Original Warrants (as set forth in the Preamble to the Original Warrants)
(the “Original Shares Issuable”) shall be amended to an amount (the “New Shares Issuable”)
equal to (x) the Original Exercise Price divided by the New Exercise Price, multiplied by (y) the Original Shares Issuable. For
avoidance of doubt, the New Shares Issuable shall be subject to all limitations, conditions, and adjustments as set forth in the
Original Warrants.

 

4.          The
definition of “Expiration Date” (as set forth in the Preamble to the Original Warrants) of each of the Original Warrants
is amended and restated in its entirety as follows:

 

“...6:00 p.m., eastern time, on April 4, 2017
(or, if such date is not a Business Day, on the Business Day immediately following such date) (the “Expiration Date”).”

 

5.          All
other provisions of the Original Warrants shall remain effective.

 

    	 

    	 

    

 

6.          This
Amendment shall for all purposes be governed by and construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed entirely within the State of New York.

 

7.          This
Amendment may be executed in any number of counterparts, each of which shall be deemed an original, and all of which together shall
constitute one and the same instrument. This Amendment may be executed and delivered by facsimile transmission and/or pdf email
transmission.
