WARRANT TO PURCHASE SHARES

OF COMMON STOCK OF

 

TAPIMMUNE INC.

 

This Warrant is issued
to__________________, or its registered assigns (including any successors or assigns, the “Warrantholder”),
which is hereby acknowledged in connection with that certain Securities Purchase Agreement, dated as of June [_], 2018, by and
among TapImmune Inc., a Nevada corporation (the “Company”) and each of the those persons and entities listed
as a Purchaser on Annex A thereto (the “Purchase Agreement”).

 

1.       EXERCISE
OF WARRANT.

 

(a)       Number
and Exercise Price of Warrant Shares; Expiration Date. Subject to the terms and conditions set forth herein and set forth in
the Purchase Agreement, the Warrantholder is entitled to purchase from the Company up to [_________] shares of the Company’s
Common Stock, $0.001 par value per share (the “Common Stock”) (as adjusted from time to time pursuant to the
provisions of this Warrant) (the “Warrant Shares”), at a purchase price of $[____] per share (the “Exercise
Price”), on or before 5:00 p.m. New York City time on the fifth anniversary of the Date of Issuance (the “Expiration
Date”) (subject to earlier termination of this Warrant as set forth herein).

 

(b)       Method
of Exercise. While this Warrant remains outstanding and exercisable in accordance with Section 1(a) above, the Warrantholder
may exercise this Warrant in accordance with Section 5 herein, by either:

 

(1)       wire
transfer to the Company or cashier’s check drawn on a United States bank made payable to the order of the Company, or

 

     

     

    

 

(2)       exercising
of the right to credit the Exercise Price against the Fair Market Value of the Warrant Shares (as defined below) at the time of
exercise (the “Net Exercise”) pursuant to Section 1(c).

 

Notwithstanding anything
herein to the contrary, the Warrantholder shall not be required to physically surrender this Warrant to the Company until the Warrantholder
has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Warrantholder
shall surrender this Warrant to the Company for cancellation within three (3) trading days of the date the final Notice of Exercise
(as defined below) is delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total
number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable
hereunder in an amount equal to the applicable number of Warrant Shares purchased. The Warrantholder and the Company shall maintain
records showing the number of Warrant Shares purchased and the date of such purchases.

 

(c)       Net
Exercise. If the Company shall receive written notice from the Warrantholder at the time of exercise of this Warrant that the
Warrantholder elects to Net Exercise the Warrant, the Company shall deliver to such Warrantholder (without payment by the Warrantholder
of any exercise price in cash) that number of Warrant Shares computed using the following formula:

 

 

Where

 

		X =	The number of Warrant Shares to be issued to the Warrantholder.

 

		Y =	The number of Warrant Shares purchasable under this Warrant or, if only a portion of the Warrant
is being exercised, the portion of the Warrant being cancelled (at the date of such calculation).

 

		A =	The Fair Market Value of one (1) share of Common Stock on the trading date immediately preceding
the date on which Warrantholder elects to exercise this Warrant.

 

		B =	The Exercise Price (as adjusted hereunder).

 

The “Fair
Market Value” of one share of Common Stock shall mean (x) the last reported sale price and, if there are no sales, the
last reported bid price, of the Common Stock on the business day prior to the date of exercise on the Trading Market on which the
Common Stock is then listed or quoted as reported by Bloomberg Financial Markets (or a comparable reporting service of national
reputation selected by the Company and reasonably acceptable to the holder if Bloomberg Financial Markets is not then reporting
sales prices of the Common Stock) (collectively, “Bloomberg”), (y) if the foregoing does not apply, the last
sales price of the Common Stock in the over-the-counter market on the pink sheets or bulletin board for such security as reported
by Bloomberg, and, if there are no sales, the last reported bid price of the Common Stock as reported by Bloomberg or, (z) if fair
market value cannot be calculated as of such date on either of the foregoing bases, the price determined in good faith by the Company’s
Board of Directors.

 

     

     

    

 

“OTC Markets”
shall mean either OTC QX or OTC QB of the OTC Markets Group, Inc.

 

“Trading Market”
shall mean any of the following markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question:
the NYSE MKT, the NASDAQ Capital Market, the NASDAQ Global Market, the NASDAQ Global Select Market, the New York Stock Exchange
or the OTC Markets (or any successors to any of the foregoing).

 

(d)       Deemed
Exercise. In the event that immediately prior to the close of business on the Expiration Date, the Fair Market Value of one
share of Common Stock (as determined in accordance with Section 1(c) above) is greater than the then applicable Exercise
Price, this Warrant shall be deemed to be automatically exercised on a net exercise issue basis pursuant to Section 1(c)
above, and the Company shall deliver the applicable number of Warrant Shares to the Warrantholder pursuant to the provisions of
Section 1(c) above and this Section 1(d).

 

2.       CERTAIN
ADJUSTMENTS.

 

(a)       Adjustment
of Number of Warrant Shares and Exercise Price. The number and kind of Warrant Shares purchasable upon exercise of this Warrant
and the Exercise Price shall be subject to adjustment from time to time as follows:

 

(1)       Dividends,
Subdivisions, Combinations and Other Issuances. If the Company shall at any time after the Date of Issuance but prior to the
Expiration Date subdivide its shares of capital stock of the same class as the Warrant Shares, by split-up or otherwise, or combine
such shares of capital stock, pay a dividend or issue additional shares of capital stock as a dividend with respect to any shares
of such capital stock, the number of Warrant Shares issuable on the exercise of this Warrant shall forthwith be proportionately
increased in the case of a subdivision, dividend or stock dividend, or proportionately decreased in the case of a combination.
Appropriate adjustments shall also be made to the Exercise Price payable per share, but the aggregate Exercise Price payable for
the total number of Warrant Shares purchasable under this Warrant (as adjusted) shall remain the same. Any adjustment under this
Section 2(a)(1) shall become effective at the close of business on the date the subdivision or combination becomes effective,
or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of such dividend.

 

(2)       Reclassification,
Reorganizations and Consolidation. In case of any reclassification, capital reorganization or change in the capital stock of
the Company (other than as a result of a subdivision, combination or stock dividend provided for in Section 2(a)(1) above)
that occurs after the Date of Issuance, then, as a condition of such reclassification, reorganization or change, lawful provision
shall be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the Warrantholder,
so that the Warrantholder shall thereafter have the right at any time prior to the expiration of this Warrant to purchase, at a
total price equal to that payable upon the exercise of this Warrant, the kind and amount of shares of stock and/or other securities
or property (including, if applicable, cash) receivable in connection with such reclassification, reorganization or change by a
holder of the same number and type of securities as were purchasable as Warrant Shares by the Warrantholders immediately prior
to such reclassification, reorganization or change. In any such case appropriate provisions shall be made with respect to the rights
and interest of the Warrantholder so that the provisions hereof shall thereafter be applicable with respect to any shares of stock
or other securities or property deliverable upon exercise hereof, and appropriate adjustments shall be made to the Exercise Price
payable hereunder, provided the aggregate Exercise Price shall remain the same (and, for the avoidance of doubt, this Warrant shall
be exclusively exercisable for such shares of stock and/or other securities or property from and after the consummation of such
reclassification or other change in the capital stock of the Company).

 

     

     

    

 

(b)       Notice
to Warrantholder. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other distribution
of cash, securities or other property in respect of its Common Stock, including, without limitation, any granting of rights or
warrants to subscribe for or purchase any capital stock of the Company or any subsidiary, (ii) authorizes or approves, enters
into any agreement contemplating or solicits stockholder approval for any Change of Control or (iii) authorizes the voluntary
dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Warrantholder a notice
of such transaction at least ten (10) business days prior to the applicable record or effective date on which a person would need
to hold Common Stock in order to participate in or vote with respect to such transaction; provided, however, that the failure to
deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such
notice.

 

(c)       Calculations.
All calculations under this Section 2 shall be made to the nearest cent or the nearest whole share, as the case may be.
For purposes of this Section 2, 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.

 

(d)       Treatment
of Warrant upon a Change of Control. 

 

(1)       If,
at any time while this Warrant is outstanding, the Company consummates a Change of Control, then a holder shall have the right
thereafter to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have
been entitled to receive upon the occurrence of such Change of Control if it had been, immediately prior to such Change of Control,
a holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (the “Alternate Consideration”).
The Company shall not effect any such Change of Control unless prior to or simultaneously with the consummation thereof, any successor
to the Company, surviving entity or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation
or entity (the “Successor Entity”) shall assume the obligation to deliver to the holder, such Alternate Consideration
as, in accordance with the foregoing provisions, the holder may be entitled to purchase, and the other obligations under this Warrant.

 

(2)       As
used in this Warrant, a “Change of Control” shall mean (i) a merger or consolidation of the Company with another
corporation (other than a merger effected exclusively for the purpose of changing the domicile of the Company), (ii) the sale,
assignment, transfer, conveyance or other disposal of all or substantially all of the properties or assets or all or a majority
of the outstanding voting shares of capital stock of the Company, (iii) a purchase, tender or exchange offer accepted by the holders
of a majority of the outstanding voting shares of capital stock of the Company, or (iv) a “person” or “group”
(as these terms are used for purposes of Section 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”)) is or shall become the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly at least a majority of the voting power of the capital stock of the Company.

 

     

     

    

 

(3)       Solely
in connection with a Change of Control that is required to be and is approved by the board of directors of the Company (which is
not controlled by Warrantholder and holders of other warrants issued as of the date hereof, or otherwise is approved by the disinterested
members of the board of directors of the Company who do not hold any warrants issued as of the date hereof), the Company or any
Successor Entity (as defined above) shall, at the Holder’s option, exercisable at any time concurrently with, or within 30
days after, the consummation of the Change of Control (or, if later, the date of the public announcement of the applicable Change
of Control), 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 Change of Control. Notwithstanding anything
herein to the contrary, the Holder may not require the Company or any Successor Entity to repurchase the Warrants for the Black
Scholes Value in connection with a Change of Control that (i) is not approved by, or is not required to be approved by, the Company’s
board of directors or (ii) is not within the Company’s control. “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 Change of Control 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 Change of Control and the Termination Date, (B) an expected volatility equal
to 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 Change
of Control and (C) a remaining option time equal to the time between the date of the public announcement of the applicable Change
of Control and the Termination Date. The payment of the Black Scholes Value will be made by wire transfer of immediately available
funds (or by delivery of such other consideration, as applicable) within five Business Days of the Holder’s election (or,
if later, on the effective date of the Change of Control).

 

3.       NO
FRACTIONAL SHARES; CHARGES, TAXES AND EXPENSES. No fractional Warrant Shares or scrip representing fractional shares will be issued
upon exercise of this Warrant. In lieu of any fractional shares which would otherwise be issuable, the Company shall pay cash equal
to the product of such fraction multiplied by the Fair Market Value of one Warrant Share. Issuance of Warrant Shares shall be made
without charge to the Warrantholder for any issue or transfer tax or other incidental expense in respect of the issuance of such
Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name
of the Warrantholder or in such name or names as may be directed by the Warrantholder; provided, however, that in
the event that Warrant Shares are to be issued in a name other than the name of the Warrantholder, this Warrant when surrendered
for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Warrantholder and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company
shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust
Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of
the Warrant Shares.

 

     

     

    

 

4.       NO
STOCKHOLDER RIGHTS. Until the exercise of this Warrant or any portion of this Warrant, the Warrantholder shall not have, nor exercise,
any rights as a stockholder of the Company (including without limitation the right to notification of stockholder meetings or the
right to receive any notice or other communication concerning the business and affairs of the Company) except as provided in Section
8 below.

 

5.       MECHANICS
OF EXERCISE.

 

(a)       Delivery
of Warrant Shares Upon Exercise. This Warrant may be exercised by the holder hereof, in whole or in part, by delivering to
the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Warrantholder
at the address of the Warrantholder appearing on the books of the Company) of a duly executed copy of the Notice of Exercise in
the form attached hereto as Exhibit A (the "Notice of Exercise") by facsimile or e-mail attachment and
paying the Exercise Price (unless the Warrantholder has elected to Net Exercise) then in effect with respect to the number of Warrant
Shares as to which the Warrant is being exercised. No ink-original Notice of Exercise shall be required, nor any medallion guarantee
(or other type of guarantee or notarization) of any Notice of Exercise shall be required This Warrant shall be deemed to have been
exercised immediately prior to the close of business on the date of the delivery to the Company of the Notice of Exercise and payment
of the Exercise Price (unless the Warrantholder has elected to Net Exercise) as provided above, and the person entitled to receive
the Warrant Shares issuable upon such exercise shall be treated for all purposes as the holder of such shares of record as of the
close of business on such date. Warrant Shares purchased hereunder shall be transmitted by the Company’s transfer agent to
the Warrantholder by crediting the account of the holder’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
the holder or (B) the shares are eligible for resale by the holder without volume or manner-of-sale limitations pursuant to Rule
144, and otherwise by physical delivery to the address specified by the holder in the Notice of Exercise by the end of the day
on the date that is two (2) trading days from the delivery to the Company of the Notice of Exercise and payment of the aggregate
Exercise Price (unless exercised by means of a cashless exercise pursuant to Section 1(c)) (the “Warrant Share
Delivery Date”). The Warrant Shares shall be deemed to have been issued, and the 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 Net Exercise) and all taxes required to be paid by
the holder, if any, prior to the issuance of such shares, having been paid.

 

     

     

    

 

(b)       Rescission
Rights. If the Company fails to cause the transfer agent to transmit to the Warrantholder the Warrant Shares pursuant to Section
5(a) by the Warrant Share Delivery Date, then the Warrantholder will have the right to rescind such exercise.

 

6.       CERTIFICATE
OF ADJUSTMENT. Whenever the Exercise Price or number or type of securities issuable upon exercise of this Warrant is adjusted,
as herein provided, the Company shall, at its expense, promptly deliver to the Warrantholder a certificate of an officer of the
Company setting forth the nature of such adjustment and showing in detail the facts upon which such adjustment is based.

 

7.       COMPLIANCE
WITH SECURITIES LAWS.

 

(a)       The
Warrantholder understands that this Warrant and the Warrant Shares are characterized as “restricted securities” under
the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering
and that under such laws and applicable regulations this Warrant and the Warrant Shares may be resold without registration under
the Securities Act only in certain limited circumstances. In this connection, the Warrantholder represents that it is familiar
with Rule 144 under the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the
Securities Act.

 

(b)       Prior
and as a condition to the sale or transfer of the Warrant Shares issuable upon exercise of this Warrant, the Warrantholder shall
furnish to the Company such certificates, representations, agreements and other information, as the Company or the Company’s
transfer agent reasonably may require to confirm that such sale or transfer is being made pursuant to an exemption from, or in
a transaction not subject to, the registration requirements of the Securities Act, unless such Warrant Shares are being sold or
transferred pursuant to an effective registration statement.

 

(c)       The
Warrantholder acknowledges that the Company may place a restrictive legend on the Warrant Shares issuable upon exercise of this
Warrant in order to comply with applicable securities laws, in substantially the following form and substance, unless such Warrant
Shares are otherwise freely tradable under Rule 144 of the Securities Act:

 

“THE
SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED,
SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A TRANSACTION WHICH IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION, IN
EACH CASE IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS, AND IN THE CASE OF A TRANSACTION EXEMPT FROM, OR NOT SUBJECT TO, SUCH
REGISTRATION, UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT
REQUIRE REGISTRATION UNDER THE SECURITIES ACT AND SUCH OTHER APPLICABLE LAWS.”

 

     

     

    

 

8.       REPLACEMENT
OF WARRANTS. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this
Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement reasonably
satisfactory in form and amount to the Company (but not the posting of any surety or other bond) or, in the case of any such mutilation,
on surrender and cancellation of such Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new Warrant
of like tenor.

 

9.       NO
IMPAIRMENT. Except to the extent as may be waived by the Warrantholder, the Company will not, by amendment of its charter or through
a Change of Control, dissolution, sale of assets 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 action as may be necessary or appropriate in order to protect the rights of the Warrantholder against impairment.

 

10.       TRADING
DAYS. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall
be other than a day on which the Common Stock is traded on the Trading Market, then such action may be taken or such right may
be exercised on the next succeeding day on which the Common Stock is so traded.

 

11.       TRANSFERS;
EXCHANGES.

 

(a)       Subject
to compliance with applicable federal and state securities laws and Section 7 hereof, this Warrant may be transferred by
the Warrantholder to any Affiliate (as defined below) with respect to any or all of the Warrant Shares purchasable hereunder (a
“Permitted Transfer”). For a transfer of this Warrant as an entirety by the Warrantholder, upon surrender of
this Warrant to the Company, together with the Notice of Assignment in the form attached hereto as Exhibit B duly completed
and executed on behalf of the Warrantholder, the Company shall issue a new Warrant of the same denomination to the assignee. For
a transfer of this Warrant with respect to a portion of the Warrant Shares purchasable hereunder, upon surrender of this Warrant
to the Company, together with the Notice of Assignment in the form attached hereto as Exhibit B duly completed and executed
on behalf of the Warrantholder, the Company shall issue a new Warrant to the assignee, in such denomination as shall be requested
by the Warrantholder, and shall issue to the Warrantholder a new Warrant covering the number of shares in respect of which this
Warrant shall not have been transferred. The term “Affiliate” as used herein means, with respect to any person,
any other person that, directly or indirectly through one or more intermediaries, controls, is controlled by or is under common
control with such person, and any officers, employees or partners of the Warrantholder.

 

     

     

    

 

(b)       Upon
any Permitted Transfer, this Warrant is exchangeable, without expense, at the option of the Warrantholder, upon presentation and
surrender hereof to the Company for other warrants of different denominations entitling the holder thereof to purchase in the aggregate
the same number of shares of Common Stock purchasable hereunder. This Warrant may be divided or combined with other warrants that
carry the same rights upon presentation hereof at the principal office of the Company together with a written notice specifying
the denominations in which new warrants are to be issued to the Warrantholder and signed by the Warrantholder hereof. The term
“Warrants” as used herein includes any warrants into which this Warrant may be divided or exchanged.

 

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

 

13.       MISCELLANEOUS.

 

(a)       This
Agreement shall be governed by and construed in accordance with the laws of the United States of America and the State of New York,
both substantive and remedial, without regard to New York conflicts of law principles. Any judicial proceeding brought under this
Agreement or any dispute arising out of this Agreement or any matter related hereto shall be brought in the courts of the State
of New York, New York County, or in the United States District Court for the Southern District of New York.

 

(b)       All
notices, requests, consents and other communications hereunder shall be in writing, shall be sent by confirmed facsimile or electronic
mail, or mailed by first-class registered or certified airmail, or nationally recognized overnight express courier, postage prepaid,
and shall be deemed given when so sent in the case of facsimile or electronic mail transmission, or when so received in the case

pursuant to a Current Report on Form 8-K.

 

(c)       The
invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provisions.

any Subsidiary, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure
or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant
in favor of any third party, and the continued employment of each such executive officer does not subject the Company or any of
its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance
with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and
conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

(l)          Compliance.

waived that, with notice or lapse of time or both, would result in a default by the Company or any Subsidiary under), nor has the
Company or any Subsidiary received notice of a claim that it is in default under or that it is in violation of, any indenture,
loan or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its properties is

(m)          Regulatory
Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal,
state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports,
except where the failure to possess such permits could not reasonably be expected to result in a Material Adverse Effect (“Material
Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation
or modification of any Material Permit.

 

(n)          Title
to Assets. The Company and the Subsidiaries have good and marketable title in fee simple to all real property owned by them
and good and marketable title in all personal property owned by them that is material to the business of the Company and the Subsidiaries,
in each case free and clear of all Liens, except for (i) Liens as do not materially affect the value of such property and do not
materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries and (ii) Liens
for the payment of federal, state or other taxes, for which appropriate reserves have been made in accordance with GAAP and, the
payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease by the Company

Property. The Company and the Subsidiaries have, or have rights to use, all patents, patent applications, trademarks, trademark
applications, service marks, trade names, trade secrets, inventions, copyrights, licenses and other intellectual property rights
and similar rights necessary or required for use in connection with their respective businesses as described in the SEC Reports
and which the failure to so have could have a Material Adverse Effect (collectively, the “Intellectual Property Rights”).
None of, and neither the Company nor any Subsidiary has received a notice (written or otherwise) that any of, the Intellectual
Property Rights has expired, terminated or been abandoned, or is expected to expire or terminate or be abandoned, within two (2)
years from the date of this Agreement. Neither the Company nor any Subsidiary has received, since the date of the latest audited
financial statements included within the SEC Reports, a written notice of a claim or otherwise has any knowledge that the Intellectual
Property Rights violate or infringe upon the rights of any Person, except as could not have or reasonably be expected to not have
a Material Adverse Effect. To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is
no existing infringement by another Person of any of the Intellectual Property Rights. The Company and its Subsidiaries have taken
reasonable security measures to protect the secrecy, confidentiality and value of all of their intellectual properties, except
where failure to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged, including,
but not limited to, directors and officers insurance coverage at least equal to the sum of all of the Purchasers’ Aggregate
Purchase Prices. Neither the Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing
insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to
continue its business without a significant increase in cost.

Internal Accounting Controls. The Company and the Subsidiaries are in compliance with any and all applicable requirements of
the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and any and all applicable rules and regulations promulgated
by the Commission thereunder that are effective as of the date hereof and as of the Closing Date. The Company and the Subsidiaries
maintain a system of internal accounting controls sufficient to provide reasonable assurance that: (i) transactions are executed
in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted
only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is

Company and the Subsidiaries have established disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and
15d-15(e)) for the Company and the Subsidiaries and designed such disclosure controls and procedures to ensure that information
required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized
and reported, within the time periods specified in the Commission’s rules and forms. The Company’s certifying officers
have evaluated the effectiveness of the disclosure controls and procedures of the Company and the Subsidiaries as of the end of
the period covered by the most recently filed periodic report under the Exchange Act (such date, the “Evaluation Date”).
The Company presented in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers
about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the
Evaluation Date, there have been no changes in the internal control over financial reporting (as such term is defined in the Exchange
Act) of the Company and its Subsidiaries that have materially affected, or is reasonably likely to materially affect, the internal
control over financial reporting of the Company and its Subsidiaries.

to registration under the Investment Company Act of 1940, as amended.

 

(u)          Registration
Rights; Private Placement. Except as set forth on Schedule 3.1(u) or pursuant to the Agreements, no Person has any right
to cause the Company or any Subsidiary to effect the registration under the Securities Act of any securities of the Company or
any Subsidiary. Assuming the accuracy of the Purchasers’ representations and warranties set forth in this Agreement and the
Other Agreements, no registration under the Securities Act is required for the offer and sale of the Securities by the Company
to the Purchasers as contemplated hereby. Subject to obtaining the Required Shareholder Approval, the issuance and sale of the
Securities does not contravene the rules and regulations of the Trading Market.

(v)         Listing
and Maintenance Requirements. The Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange Act, and the
Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration
of the Common Stock under the Exchange Act nor has the Company received any notification that the Commission is contemplating terminating
such registration. The Company has not, in the 12 months preceding the date hereof, received notice from any Trading Market on
which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or
maintenance requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable
future continue to be, in compliance with all such listing and maintenance requirements.

 

(w)          Application
of Takeover Protections. The Company and the Board of Directors have taken all necessary action, if any, in order to render
inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement)
or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar charter documents)
or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and
the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation
as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.

 

(x)          No
Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section
3.2, neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly,
made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this
offering of the Securities to be integrated with prior offerings by the Company for purposes of (i) the Securities Act which would
require the registration of any such securities under the Securities Act, or (ii) any applicable shareholder approval provisions
of any Trading Market on which any of the securities of the Company are listed or designated.

(y)          Solvency.
Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the
Company of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value of the Company’s assets exceeds
the amount that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including
known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry
on its business as now conducted and as proposed to be conducted including its capital needs taking into account the particular
capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital availability
thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate
all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or in
respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability
to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt).
The Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation
under the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date. Schedule 3.1(y) sets
forth as of the date hereof all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which the
Company or any Subsidiary has commitments. For the purposes of this Agreement, “Indebtedness” means (x) any
liabilities for borrowed money or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary
course of business), (y) all guaranties, endorsements and other contingent obligations in respect of indebtedness of others, whether
or not the same are or should be reflected in the Company’s consolidated balance sheet (or the notes thereto), except guaranties
by endorsement of negotiable instruments for deposit or collection or similar transactions in the ordinary course of business;
and (z) the present value of any lease payments in excess of $50,000 due under leases required to be capitalized in accordance
with GAAP. Neither the Company nor any Subsidiary is in default with respect to any Indebtedness.

 

(z)          Tax
Status. Except for matters that would not, individually or in the aggregate, have or reasonably be expected to result in a
Material Adverse Effect, the Company and its Subsidiaries each (i) has made or filed all United States federal, state and local
income and all foreign income and franchise tax returns, reports and declarations required by any jurisdiction to which it is subject,
(ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due
on such returns, reports and declarations and (iii) has set aside on its books provision reasonably adequate for the payment of
all material taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There are no unpaid
taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company or
of any Subsidiary know of no basis for any such claim.

 

(aa)         Foreign
Corrupt Practices. Neither the Company nor any Subsidiary, nor to the knowledge of the Company or any Subsidiary, any agent
or other person acting on behalf of the Company or any Subsidiary, has (i) directly or indirectly, used any funds for unlawful
contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity, (ii) made any
unlawful payment to foreign or domestic government officials or employees or to any foreign or domestic political parties or campaigns

provision of FCPA. The Company, the Subsidiaries and, to the knowledge of the Company, its affiliates have conducted their businesses
in compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and reasonably expected
to ensure, continued compliance therewith.

The Purchaser understands that the federal securities laws impose restrictions on trading based on information regarding this offering.
This obligation will terminate upon the issuance of the press release relating to the transactions contemplated hereby on the Trading
Day immediately following the Closing Date. In addition to the above, the Purchaser shall maintain in confidence the receipt and

(f)          Investment

its Subsidiaries, or any of their respective officers, directors, employees or agents in connection with the transactions contemplated
by the Transaction Documents.

 

(g)          Risk
of Loss. The Purchaser understands that its investment in the Shares and the Warrants involves a significant degree of risk,

of the risk factors related to the Purchaser’s purchase of the Shares and the Warrants.

 

(h)          Legend.
The Purchaser understands that, until such time as the Shares and the Warrant Shares may be sold pursuant to Rule 144 under the
Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold
and except if and to the extent otherwise provided below in this Section 3.2, the Shares and the Warrant Shares will bear
a restrictive legend in substantially the following form:

 

    	 	24	 

     

    

  

“THE SHARES
EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”),
OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION. THE SHARES MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED
EXCEPT (1) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OR (2) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE STATE SECURITIES LAWS AND THE SECURITIES LAWS OF OTHER
JURISDICTIONS, AND IN THE CASE OF A TRANSACTION EXEMPT FROM REGISTRATION, UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL
REASONABLY SATISFACTORY TO IT THAT SUCH TRANSACTION DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT AND SUCH OTHER APPLICABLE
LAWS.”

 

The Shares and the
Warrant Shares shall not be required to contain any legend (including the legend set forth above in this Section 3.2 hereof),
(i) while a registration statement (including the Resale Registration Statement) covering the resale of such security is effective
under the Securities Act, (ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144 (assuming cashless exercise
of the Warrants), (iii) if such Shares or Warrant Shares are eligible for immediate sale under Rule 144 (assuming cashless exercise
of the Warrants) without any volume or manner-of-sale restrictions, or (iv) if such legend is not required under applicable requirements
of the Securities Act (including judicial interpretations and pronouncements issued by the Commission). The Company shall cause
its counsel to issue a legal opinion to the Company’s transfer agent or the Purchaser if required by the Company’s
transfer agent to effect the removal of the legend hereunder, or if requested by the Purchaser, respectively, provided that
such legend is not required pursuant to the foregoing provisions of this paragraph. The Company agrees that at such time as such
legend is no longer required under this Section 3.2 (including, without limitation, following the effective date of the
Resale Registration Statement), it will, no later than the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days
comprising the Standard Settlement Period (as defined below) following the delivery by the Purchaser to the Company or the Company’s
transfer agent of a certificate representing Shares or Warrant Shares, as the case may be, issued with a restrictive legend (such
date, the “Legend Removal Date”), deliver or cause to be delivered to the Purchaser such shares that are free
from all restrictive and other legends in such manner as directed by the Purchaser. The Company may not make any notation on its
records or give instructions to the Company’s transfer agent that enlarge the restrictions on transfer set forth in this
Section 3.2. The Company shall pay all reasonable fees and expenses (including the reasonable fees and expenses of legal
counsel) relating to the removal of the restrictive legends pursuant to this Section 3.2(h). As used herein, “Standard
Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s
primary trading market with respect to the Common Stock as in effect on the date of delivery of a certificate representing Shares
or Warrant Shares, as the case may be, issued with a restrictive legend.

 

The Purchaser, severally
and not jointly with the Other Purchasers, agrees with the Company that the Purchaser will sell any Securities pursuant to either
the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption
therefrom, and that if Securities are sold pursuant to a Resale Registration Statement, they will be sold in compliance with the
plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates representing
Securities as set forth in this Section 3.2 is predicated upon the Company’s reliance upon this understanding.

 

    	 	25	 

     

    

  

(i)          Stop
Transfer. When issued, the Shares and the Warrant Shares purchased hereunder will be subject to a stop transfer order with
the Company’s transfer agent that restricts the transfer of such shares except upon receipt by the transfer agent, in accordance
with the provisions of Section 3.2(k) below, of a written confirmation from the Purchaser to the effect that the Purchaser
has satisfied its prospectus delivery requirements or upon receipt by the transfer agent of written instructions from the Company
authorizing such transfer.

 

(j)          Residency.
The Purchaser’s principal executive offices are in the jurisdiction set forth immediately below the Purchaser’s name
on the signature pages hereto.

 

(k)          Public
Sale or Distribution. (a) The Purchaser hereby covenants with the Company not to make any sale of the Shares or the Warrant
Shares under the Resale Registration Statement without complying with the provisions of this Agreement and without effectively
causing the prospectus delivery requirement under the Securities Act to be satisfied (whether physically or through compliance
with Rule 172 under the Securities Act or any similar rule), and the Purchaser acknowledges and agrees that such Shares and Warrant
Shares are not transferable on the books of the Company unless the certificate submitted to the transfer agent evidencing the Shares
or the Warrant Shares, as applicable, is accompanied by a separate Purchaser’s Certificate of Subsequent Sale: (i) in the
form of Appendix II hereto, (ii) executed by an officer of, or other authorized person designated by, the Purchaser, and
(iii) to the effect that (A) the Shares or the Warrant Shares, as applicable, have been sold in accordance with the Resale Registration
Statement, the Securities Act and any applicable state securities or Blue Sky laws and (B) the prospectus delivery requirement
effectively has been satisfied. The Purchaser acknowledges that there may occasionally be times when the Company must suspend the
use of the prospectus (the “Prospectus”) forming a part of the Resale Registration Statement (a “Suspension”)
until such time as an amendment to the Resale Registration Statement has been filed by the Company and declared effective by the
Commission, or until such time as the Company has filed an appropriate report with the Commission pursuant to the Exchange Act.
Without the Company’s prior written consent, which consent shall not unreasonably be withheld or delayed, the Purchaser shall
not use any written materials to offer the Shares or the Warrant Shares for resale other than the Prospectus, including any “free
writing prospectus” as defined in Rule 405 under the Securities Act. The Purchaser covenants that it will not sell any Shares
or Warrant Shares pursuant to said Prospectus during the period commencing at the time when Company gives the Purchaser written
notice of the Suspension of the use of said Prospectus and ending at the time when the Company gives the Purchaser written notice
that the Purchaser may thereafter effect sales pursuant to said Prospectus. Notwithstanding the foregoing, (i) the Company agrees
that no Suspension shall be for a period of longer than 30 consecutive days, and no Suspension shall be for a period longer than
60 days in the aggregate in any 360-day period, and (ii) the Company agrees that, if the legend removal process described in Section
3.2(h) commenced prior to the beginning of a Suspension, then after the completion of such legend removal process, the Company
shall honor any transfer of the de-legended Shares or Warrant Shares, even if such transfer occurs during the Suspension period.
The Purchaser further covenants to notify the Company promptly of the sale of all of its Shares and Warrant Shares.

 

    	 	26	 

     

    

  

(b) At any
time that the Purchaser is an affiliate of the Company, any resale of the Shares or the Warrant Shares that purports to be effected
under Rule 144 shall comply with all of the requirements of such rule, including the “manner of sale” requirements
set forth in Rule 144(f).

 

(l)          Organization;
Validity; Enforcement. The Purchaser further represents and warrants to, and covenants with, the Company that (i) the Purchaser
has full right, power, authority and capacity to enter into this Agreement and to consummate the transactions contemplated hereby
and has taken all necessary action to authorize the execution, delivery and performance of this Agreement, (ii) the making and
performance of this Agreement by the Purchaser and the consummation of the transactions herein contemplated will not violate any
provision of the organizational documents of the Purchaser or conflict with, result in the breach or violation of, or constitute,
either by itself or upon notice or the passage of time or both, a default under any material agreement, mortgage, deed of trust,
lease, franchise, license, indenture, permit or other instrument to which the Purchaser is a party or, any statute or any authorization,
judgment, decree, order, rule or regulation of any court or any regulatory body, administrative agency or other governmental agency
or body applicable to the Purchaser, (iii) no consent, approval, authorization or other order of any court, regulatory body, administrative
agency or other governmental agency or body is required on the part of the Purchaser for the execution and delivery of this Agreement
or the consummation of the transactions contemplated by this Agreement, (iv) upon the execution and delivery of this Agreement,
this Agreement shall constitute a legal, valid and binding obligation of the Purchaser, enforceable in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of
general application relating to or the enforcement of creditor’s rights and the application of equitable principles relating
to the availability of remedies, and except as rights to indemnity or contribution, including, but not limited to, the indemnification
provisions set forth in Section 4.2 of this Agreement, may be limited by federal or state securities laws or the public
policy underlying such laws and (v) there is not in effect any order enjoining or restraining the Purchaser from entering into
or engaging in any of the transactions contemplated by this Agreement.

 

    	 	27	 

     

    

  

(m)         Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not,
nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any
purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that
such Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting
forth the material terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding
the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage
separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions
made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall
only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase
the Securities covered by this Agreement. Other than to other Persons party to this Agreement or to such Purchaser’s representatives,
including, without limitation, its officers, directors, partners, legal and other advisors, employees, agents and Affiliates, such
Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence
and terms of this transaction). Notwithstanding the foregoing, for the avoidance of doubt, nothing contained herein shall constitute
a representation or warranty, or preclude any actions, with respect to the identification of the availability of, or securing of,
available shares to borrow in order to effect Short Sales or similar transactions in the future.

 

(n)          Access
to Information. The Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including all
exhibits and schedules thereto) and the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has deemed
necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of
the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial
condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment;
and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable
effort or expense that is necessary to make an informed investment decision with respect to the investment. The Purchaser acknowledges
and agrees that neither the Placement Agents nor any Affiliate of the Placement Agents has provided the Purchaser with any information
or advice with respect to the Securities nor is such information or advice necessary or desired. Neither the Placement Agents nor
any of their Affiliates have made or makes any representation as to the Company or the quality of the Securities and the Placement
Agents and any of their Affiliates may have acquired non-public information with respect to the Company which such Purchaser agrees
need not be provided to it. In connection with the issuance of the Securities to the Purchaser, neither the Placement Agents nor
any of their Affiliates have acted as a financial advisor or fiduciary to such Purchaser.

 

(o)          Short
Sales. The Purchaser shall not take, prior to the earlier to occur of (1) the date on which the Resale Registration Statement
is declared effective by the Commission, or (2) the date that is 180 days from the Closing Date, any action that has caused or
will cause the Purchaser to have, directly or indirectly, effected or agreed to effect any short sale, whether or not against the
box, established any “put equivalent position” (as defined in Rule 16a-1(h) under the Exchange Act with respect
to the Common Stock, granted any other right (including, without limitation, any put or call option) with respect to the Common
Stock or with respect to any security that includes, relates to or derived any significant part of its value from the Common Stock.

 

    	 	28	 

     

    

  

The Company acknowledges and agrees that
the representations contained in Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the
Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any
other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the
consummation of the transaction contemplated hereby.

    	 	29	 

     

    

 

(d)          Notwithstanding
anything express or implied in this Agreement or any Other Agreement to the contrary, in the event that the Commission for any

the resale of the Reduction Securities (or such portion thereof as the Commission will allow to be registered for resale at such
time) for an offering to be made on a continuous basis pursuant to Rule 415 and shall file such new registration statement with
the Commission within thirty (30) calendar days following (x) the date that the Commission would allow or permit such additional
registration statement to be filed or (y) the date on which the Company first learned the date that the Commission would allow
or permit such additional registration statement to be filed, whichever of (x) or (y) is the later date.

 

(e)          Furnish
to the Purchaser with respect to the Shares and the Warrant Shares registered under the Resale Registration Statement (and to each
underwriter, if any, of such Shares and Warrant Shares) such number of copies of prospectuses and such other documents as the Purchaser
may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Shares and the Warrant
Shares by the Purchaser.

 

(f)          File
documents required of the Company for normal Blue Sky clearance in states specified in writing by the Purchaser; provided,

expenses, if any, of counsel or other advisers to the Purchaser or the Other Purchasers or underwriting discounts, brokerage fees
and commissions incurred by the Purchaser or the Other Purchasers, if any in connection with the offering of the Shares and the
Warrant Shares on behalf of the Purchasers pursuant to the Resale Registration Statement.

 

    	 	30	 

     

    

 

(h)          Rule
144. At any time during the period commencing on the six (6) month anniversary of the date hereof and ending at such time that
the Shares and the Warrant Shares may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and
otherwise without restriction or limitation pursuant to Rule 144, if the Company (1) shall fail for any reason to satisfy the current
public information requirement under Rule 144(c) or (2) has ever been an issuer described in Rule 144(i)(1)(i) or becomes such
an issuer in the future, and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (each of the events described
in the foregoing clause (1) or the foregoing clause (2) of this Section 4.1(h) being hereinafter referred to as a “Public
Information Failure”), then the Company shall pay to the Purchaser, as partial liquidated damages and not as a penalty,

or delays the Purchaser from transferring the Shares and Warrant Shares pursuant to Rule 144; and for any such 30-day (or shorter)
period, such payment shall be made no later than three business days following such 30-day (or shorter) period. Notwithstanding
the foregoing provisions, in no event shall the Company be obligated to pay any liquidated damages pursuant to this Section
4.1(h) (x) if any registration statement covering the resale of the Shares and the Warrant Shares by the Purchasers pursuant
to an offering to be made on a continuous basis pursuant to Rule 415 promulgated under the Securities Act has been declared effective
by the Commission and remains effective, (y) with respect to any Shares or Warrant Shares for any period of time if the Company
is obligated to pay to any Other Purchaser liquidated damages pursuant to this Section 4.1(h) of the Agreement executed
by such Other Purchaser with respect to such Shares or Warrant Shares for the same period of time, or (z) in an aggregate amount
that exceeds 10% of the purchase price paid by the Purchaser for the Shares and the Warrants pursuant to this Agreement.

 

A draft of the proposed
form of the questionnaire related to the Resale Registration Statement to be completed by the Purchaser is attached hereto as Appendix
I.

 

It is understood and
agreed that the Company has the right to take any and all steps necessary to convert the Resale Registration Statement from a Form
S-1 to a Form S-3 at any time after the Company becomes eligible to do so under applicable rules and regulations of the Commission.

 

(i)     
     Transfer of Shares or Warrant Shares After Registration. The Purchaser agrees that it
will not effect any disposition of the Shares or the Warrant Shares or its right to purchase the Shares or the Warrant Shares
that would constitute a sale within the meaning of the Securities Act or pursuant to any applicable state securities laws,
except as contemplated in the Resale Registration Statement referred to in Section 4.1 or as otherwise permitted by
law, and that it will promptly notify the Company of any changes in the information set forth in the Resale Registration
Statement regarding the Purchaser or its plan of distribution.

For the purposes of this Section 4.2:

 

(a)          For
the purpose of this Section 4.2: (i) the term “Purchaser/Affiliate” shall mean any affiliate of the Purchaser,
including a transferee who is an affiliate of the Purchaser, and any person who controls the Purchaser or any affiliate of the
Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and (ii) the term “Resale

Company agrees to indemnify and hold harmless the Purchaser and each Purchaser/Affiliate, against any losses, claims, damages,
liabilities or expenses, joint or several, to which the Purchaser or Purchaser/Affiliates may become subject, under the Securities
Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement
of any litigation, if such settlement is effected with the written consent of the Company), insofar as such losses, claims, damages,
liabilities or expenses (or actions in respect thereof as contemplated below) (i) arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in (1) the Resale Registration Statement, including the Prospectus,
financial statements and schedules, and all other documents filed as a part thereof, as amended at the time of effectiveness of
the Resale Registration Statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant
to paragraph (b) of Rule 430A, or pursuant to Rules 430B, 430C or 434, of the Rules and Regulations, or (2) the Prospectus, in

by the Purchaser or such Purchaser/Affiliate in connection with investigating, defending or preparing to defend, settling, compromising
or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not
be liable for amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without
the consent of the Company, which consent shall not be unreasonably withheld, and the Company will not be liable in any such case
to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (A) an untrue statement or
alleged untrue statement or omission or alleged omission made in the Resale Registration Statement, the Prospectus or any amendment
or supplement thereto in reliance upon and in conformity with written information furnished to the Company by or on behalf of the
Purchaser expressly for use therein; (B) the failure of the Purchaser to comply with the covenants and agreements contained in
Section 3.2 or Section 4.1(i) hereof respecting the sale of the Shares and the Warrants; (C) the inaccuracy of any

each of its officers who signed the Resale Registration Statement and each person, if any, who controls the Company within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages, liabilities
or expenses to which the Company, each of its directors, each of its officers who signed the Resale Registration Statement or controlling
person may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation,
or at common law or otherwise (including in settlement of any litigation, but only if such settlement is effected with the written
consent of the Purchaser) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated
below) arise out of or are based upon (i) any failure to comply with the covenants and agreements contained in Section 3.2
or Section 4.1(i) hereof respecting the sale of the Shares and the Warrants; (ii) the inaccuracy of any representation or
warranty made by the Purchaser herein; or (iii) any untrue or alleged untrue statement of any material fact contained in the Resale
Registration Statement, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements in the Resale
Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement
thereto not misleading in the light of the circumstances under which they were made, in each case under this clause (iii) to the
extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made
in the Resale Registration Statement, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity
with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein; and will reimburse

under this Section 4 shall not exceed the amount of net proceeds received by the Purchaser on the sale pursuant to the Resale
Registration Statement of the Shares and the Warrant Shares purchased by the Purchaser.

 

    	 	33	 

     

    

 

(d)          Promptly
after receipt by an indemnified party under this Section 4.2 of notice of the threat or commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 4.2
promptly notify the indemnifying party in writing thereof, but the omission to notify the indemnifying party will not relieve it
from any liability that it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained
in this Section 4.2 to the extent it is not prejudiced as a result of such failure. In case any such action is brought against
any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly
notified, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however,
if the defendants in any such action include both the indemnified party, and the indemnifying party and the indemnified party shall
have reasonably concluded, based on an opinion of counsel reasonably satisfactory to the indemnifying party, that there may be
a conflict of interest between the positions of the indemnifying party and the indemnified party in conducting the defense of any
such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional
to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel
to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election to assume the defense of
such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party
under this Section 4.2 for any legal or other expenses subsequently incurred by such indemnified party in connection with
the defense thereof unless (i) the indemnified party shall have employed such counsel in connection with the assumption of legal
defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall
not be liable for the expenses of more than one separate counsel, reasonably satisfactory to such indemnifying party, representing
all of the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably
satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement
of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.
The indemnifying party shall not be liable for any settlement of any action without its written consent. In no event shall any
indemnifying party be liable in respect of any amounts paid in settlement of any action unless the indemnifying party shall have
approved in writing the terms of such settlement; provided that such consent shall not be unreasonably withheld. No indemnifying
party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding
in respect of which any indemnified party is or could have been a party and indemnification could have been sought hereunder by
such indemnified party from all liability on claims that are the subject matter of such proceeding, unless such settlement (x)
includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified
Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to
or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

 

    	 	34	 

     

    

 

(e)          If
the indemnification provided for in this Section 4.2 is required by its terms but is for any reason held to be unavailable
to or otherwise insufficient to hold harmless an indemnified party under paragraphs (a), (b) or (c) of this Section 4.2
in respect to any losses, claims, damages, liabilities or expenses referred to therein, then each applicable indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities
or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company
and the Purchaser from the private placement of Common Stock hereunder or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in
clause (i) above but the relative fault of the Company and the Purchaser in connection with the statements or omissions or inaccuracies
in the representations and warranties in this Agreement and/or the Resale Registration Statement that resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received
by the Company on the one hand and the Purchaser on the other shall be deemed to be in the same proportion as the amount paid by
the Purchaser to the Company pursuant to this Agreement for the Shares and the Warrants purchased by the Purchaser that were sold
pursuant to the Resale Registration Statement bears to the difference (the “Difference”) between the amount
the Purchaser paid for the Shares and the Warrants that were sold pursuant to the Resale Registration Statement and the amount
received by the Purchaser from such sale. The relative fault of the Company on the one hand and the Purchaser on the other shall
be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or
alleged omission to state a material fact or the inaccurate or the alleged inaccurate representation and/or warranty relates to
information supplied by the Company or by the Purchaser and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in
paragraph (c) of this Section 4.2, any legal or other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. The provisions set forth in paragraph (d) of this Section 4.2 with respect
to the notice of the threat or commencement of any threat or action shall apply if a claim for contribution is to be made under
this paragraph (e); provided, however, that no additional notice shall be required with respect to any threat or
action for which notice has been given under paragraph (d) for purposes of indemnification. The Company and the Purchaser agree
that it would not be just and equitable if contribution pursuant to this Section 4.2 were determined solely by pro rata
allocation (even if the Purchaser were treated as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to in this paragraph. Notwithstanding the provisions of this Section
4.2, the Purchaser shall not be required to contribute any amount in excess of the amount by which the Difference exceeds the
amount of any damages that the Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement
or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchaser’s
obligation to contribute pursuant to this Section 4.2 are several and not joint with the Other Purchasers’ obligation
to contribute pursuant to Section 4.2 of the Agreements between the Other Purchasers and the Company.

 

    	 	35	 

     

    

  

(f)          Termination
of Conditions and Obligations. The restrictions imposed by Section 3.2 or Section 4.1(i) upon the transferability
of the Shares and the Warrant Shares shall cease and terminate as to any particular number of the Shares and the Warrant Shares
upon the earliest of (i) the passage of two years from the effective date of the Resale Registration Statement covering such Shares
or Warrant Shares, as applicable, (ii) at such time as an opinion of counsel satisfactory in form and substance to the Company
shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act, and (iii)
the Applicable Rule 144 Full Liquidity Date (as defined below).

 

(g)          Information
Available. The Company, upon the reasonable request of the Purchaser, shall make available for inspection by the Purchaser,
any underwriter participating in any disposition pursuant to the Resale Registration Statement and any attorney, accountant or
other agent retained by the Purchaser or any such underwriter, all financial and other records, pertinent corporate documents and
properties of the Company, and cause the Company’s officers, employees and independent accountants to supply all information
reasonably requested by the Purchaser or any such underwriter, attorney, accountant or agent in connection with the Resale Registration
Statement.

 

(h)          Delay
in Filing or Effectiveness of Registration Statement. If the Resale Registration Statement is not filed by the Company with
the Commission on or prior to the Filing Deadline, then for each day following the Filing Deadline until but excluding the date
the Resale Registration Statement is filed or, if earlier, until the date the Shares and the Warrant Shares purchased hereunder
may be sold pursuant to Rule 144 under the Securities Act without any restriction as to the number of securities as of a particular
date that can then be immediately sold and without the requirement to be in compliance with Rule 144(c)(1) (the “Applicable
Rule 144 Full Liquidity Date”), or if the Resale Registration Statement is not declared effective by the Commission by
the Effective Deadline (unless the Commission seeks to impose, or notifies the Company that the Commission is considering, a limitation
in the number of shares of Common Stock that the Purchaser and the Other Purchasers may include in the Resale Registration Statement,
in which case the provisions of this Section 4.2(h) shall not be applicable if the Resale Registration Statement is not
declared effective by the Commission by the Effective Deadline), then for each day following the Effective Deadline until but excluding
the date the Commission declares the Resale Registration Statement effective or, if earlier, until the Applicable Rule 144 Full
Liquidity Date, the Company shall, for each such day, pay the Purchaser with respect to any such failure, as liquidated damages
and not as a penalty, an amount per 30-day period equal to 1.0% of the purchase price paid by the Purchaser for its Securities
pursuant to this Agreement; and for any such 30-day period, such payment shall be made no later than three business days following
such 30-day period. If the Purchaser shall be prohibited from selling Shares or Warrant Shares under the Resale Registration Statement
as a result of a Suspension of more than thirty (30) days or Suspensions on more than two (2) occasions of not more than thirty
(30) days each in any 12-month period, then for each day prior to the Applicable Rule 144 Full Liquidity Date on which a Suspension
is in effect that exceeds the maximum allowed period for a Suspension or Suspensions, but not including any day on which a Suspension
is lifted, the Company shall pay the Purchaser, as liquidated damages and not as a penalty, an amount per 30-day period equal to
1.0% of the purchase price paid by the Purchaser for its Shares or Warrant Shares, as applicable, pursuant to this Agreement for
each such 30-day period, and such payment shall be made no later than the first business day of the calendar month next succeeding
the month in which such day occurs. For purposes of this Section 4.2(h), a Suspension shall be deemed lifted on the date
that notice that the Suspension has been lifted is delivered to the Purchaser pursuant to Section 3.2(k) of this Agreement.
Any payments made pursuant to this Section 4.2(h) shall not constitute the Purchaser’s exclusive remedy for such events;
provided, however, that any payments made by the Purchaser pursuant to this Section 4.2(h) shall reduce the
amount of any damages that the Purchaser may be entitled to as a remedy for such events. Notwithstanding the foregoing provisions,
in no event shall the Company be obligated to pay any liquidated damages pursuant to this Section 4.2(h)(i) with respect
to any Shares or Warrant Shares for any period of time if the Company is obligated to pay to any Other Purchaser liquidated damages
pursuant to Section 4.2(h) of the Agreement executed by such Other Purchaser with respect to the exact same Shares or Warrant
Shares for the same period of time or (ii) in an aggregate amount that exceeds 10% of the purchase price paid by the Purchaser
for the Shares and the Warrants pursuant to this Agreement. Such payments shall be made to the Purchasers in cash.

 

    	 	36	 

     

    

  

4.3           Non-Exclusive
Remedy. The respective rights of indemnification of each of the Company and the Purchaser under this Section 4 shall
not be exclusive of any other remedy available to either the Company or the Purchaser under applicable law.

 

4.4           Future
Issuances of Common Stock or Common Stock Equivalents. From the date hereof until 30 days after the effective date of the Resale
Registration Statement, neither the Company nor any Subsidiary shall issue, file a registration statement with the Commission with
respect to, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common
Stock Equivalents. Notwithstanding the foregoing, this Section 4.4 shall not apply in respect of an Exempt Issuance or securities
issued pursuant to the Bridge Financing Agreements, the Merger Agreement or the Reincorporation.

the Purchaser of the Securities being purchased and the payment therefor.

 

6.11         Execution.
This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being
understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission
or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the
party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf”
signature page were an original thereof.

 

6.12         Severability.
If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal,
void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full
force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that
they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

 

6.13         Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, the Purchaser
and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages
may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents
and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy
at law would be adequate.

6.14         Independent
Nature of Purchasers’ Obligations and Rights. The obligations of the Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any
other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the
rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser
to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate
legal counsel in its review and negotiation of the Transaction Documents. Mayer Brown does not represent any of the Purchasers
and only represents the Placement Agents. The Company has elected to provide all Purchasers with the same terms and Transaction
Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers. It
is expressly understood and agreed that each provision contained in this Agreement and in each other Transaction Document is between
the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not between and among the
Purchasers.

 

6.15         Liquidated
Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction
Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other
amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages
or other amounts are due and payable shall have been canceled.

 

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

 

6.17         Construction.
The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction
Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting
party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and
every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after
the date of this Agreement.

 

    	 	42	 

     

    

  

6.18         WAIVER
OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES
EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY
AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
