and Warranties of the Company. Except (i) as set forth in the Disclosure Schedules that have been prepared by the Company and
delivered to the Purchasers in connection with the execution and delivery of this Agreement (it being agreed that any disclosures

or enforceability of any Transaction Document, (ii) a material adverse effect on the results of operations, assets, business,
prospects or condition (financial or otherwise) of the Company and the Subsidiaries, taken as a whole, or (iii) a material adverse

affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance,

(y)       Disclosure.
Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company
confirms that neither it nor, to the Company's knowledge, any other Person acting on its behalf has provided any of the Purchasers
or their agents or counsel with any information that it believes constitutes or might constitute material, non-public information.
The Company understands and confirms that the Purchasers will rely on the foregoing representation in effecting transactions in
securities of the Company. All of the disclosure furnished by or, to the Company's knowledge, on behalf of the Company to the
Purchasers regarding the Company and its Subsidiaries, their respective businesses and the transactions contemplated hereby, including
the Disclosure Schedules to this Agreement, is true and correct and does not contain any untrue statement of a material fact or
omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under
which they were made, not misleading. The press releases disseminated by the Company during the 12 months preceding the date of
this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they
were made and when made, not misleading. The Company acknowledges and agrees that no Purchaser makes or has made any representations
or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3.2 hereof.


 


(z)       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 the Shares, Underlying Shares, Warrants or Warrant Shares 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.


 


(aa)Solvency.

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(aa)
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

Securities are outstanding, including, without limitation, during the periods that the value of the Underlying Shares or Warrant
Shares deliverable with respect to Securities are being determined, and (z) such hedging activities (if any) could reduce the
value of the existing stockholders’ equity interests in the Company at and after the time that the hedging activities are
being conducted. The Company acknowledges that such aforementioned hedging activities do not constitute a breach of any of the
Transaction Documents.

Such Purchaser acknowledges and agrees that neither the Placement Agent nor any Affiliate of the Placement Agent has provided
such Purchaser with any information or advice with respect to the Securities nor is such information or advice necessary or desired.
Neither the Placement Agent nor any Affiliate has made or makes any representation as to the Company or the quality of the Securities
and the Placement Agent and any Affiliate 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 such Purchaser, neither the Placement

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 locating or borrowing shares in order
to effect Short Sales or similar transactions in the future.


 


(g)       General
Solicitation. Such Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication
regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented
at any seminar or, to the knowledge of such Purchaser, any other general solicitation or general advertisement.


 


(h)       Acknowledgement
of Placement Agent Fees. Such Purchaser hereby acknowledges that the Company has agreed to pay the Placement Agent the following
compensation in connection with the sale of the Securities: (i).eight percent (8%) of the gross proceeds of the Securities purchased,
(ii) reimbursement of offering expenses in the amount of $42,500, (iii) issuance of a placement agent warrants to purchase eight
percent (8%) of the aggregate number of Underlying Shares and Warrant Shares underlying the Shares and the Warrants purchased
in the Offering, which placement agent warrants shall be exercisable for 5 years commencing six (6) months following the closing
of the transaction contemplated hereby at a per share price of $1.47, and (iv) the grant to the Placement Agent of indemnification,
advancement and contribution rights.


 


The
Company acknowledges and agrees that the representations contained in this 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 transactions contemplated hereby. Notwithstanding the foregoing, for the avoidance
of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any actions, with respect to locating

ARTICLE
IV

OTHER AGREEMENTS OF THE PARTIES


 


4.1       Removal
of Legends.


 


(a)       The
Shares, Underlying Shares, Warrants and Warrant Shares may only be disposed of in compliance with state and federal securities
laws. In connection with any transfer of Shares, Underlying Shares, Warrants or Warrant Shares other than pursuant to an effective
registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser or in connection with a pledge as contemplated
in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by
the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory
to the Company, to the effect that such transfer does not require registration of such transferred Share or Warrant under the
Securities Act.


 


(b)       The
Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Shares, Underlying Shares,
Warrants or Warrant Shares in the following form:


 


NEITHER
THIS SECURITY NOR THE SECURITIES INTO WHICH THIS SECURITY IS EXERCISABLE HAS BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE
COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT
OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO,
THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY AND
THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED
BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a)
UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.


 


The
Company acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a
registered broker-dealer or grant a security interest in some or all of the Shares, Underlying Shares, Warrants or Warrant Shares
to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and,
if required under the terms of such arrangement, such Purchaser may transfer pledged or secured Shares, Underlying Shares, Warrants
or Warrant Shares to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company
and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further,
no notice shall be required of such pledge. At a Purchaser’s expense, the Company will execute and deliver such reasonable
documentation as a pledgee or secured party of Shares, Underlying Shares, Warrants and Warrant Shares such Purchaser may reasonably
request in connection with a pledge or transfer of the Shares, Underlying Shares, Warrants or Warrant Shares.


 




    	22



    	 



    

 


(c)       Certificates
evidencing the Underlying Shares or Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b)
hereof): (i) while a registration statement covering the resale of such security is effective under the Securities Act, or (ii)
following any sale of such Underlying Shares or Warrant Shares pursuant to Rule 144 (assuming cashless exercise of the Warrants),
or (iii) if such Underlying Shares are eligible for sale under Rule 144, or, assuming cashless exercise of the Warrants, if such
Warrant Shares are eligible for sale under Rule 144, or (iv) 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). The Company shall
cause its counsel to issue a legal opinion to the Transfer Agent or the Purchaser promptly if required by the Transfer Agent to
effect the removal of the legend hereunder, or if requested by a Purchaser, respectively. If all or any portion of a Warrant is
exercised or if a Share is converted at a time when there is an effective registration statement to cover the resale of the Warrant
Shares or Underlying Shares, as applicable, or if such Warrant Shares or Underlying Shares, as applicable, may be sold under Rule
144, or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations
and pronouncements issued by the staff of the Commission) then such Warrant Shares or Underlying Shares shall be issued free of
all legends. The Company agrees that following such time as such legend is no longer required under this Section 4.1(c), the Company
will, no later than the earlier of (i) one (1) Trading Day and (ii) the number of Trading Days comprising the Standard Settlement
Period (as defined below) following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing
Warrant Shares or Underlying Shares, as applicable, issued with a restrictive legend (such date, the “Legend Removal
Date”), deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from
all restrictive and other legends , so long as, no later than the applicable date in clause (i) or (ii), the Purchaser and the
Purchaser’s broker have provided to the Company or the Company’s transfer agent all customary documents and have taken
all customary actions requested by the Company’s transfer agent in connection with the foregoing delivery.. The Company
may not make any notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer
set forth in this Section 4. Warrant Shares or Underlying Shares subject to legend removal hereunder shall be transmitted by the
Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company
System as directed by such Purchaser. 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 Warrant Shares or Underlying Shares issued with a restrictive
legend.


 




    	23



    	 



    

 


(d)       In
addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial liquidated
damages and not as a penalty, for each $1,000 of Warrant Shares or Underlying Shares (based on the VWAP of the Common Stock on
the date such Securities are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section
4.1(c), $10 per Trading Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue)
for each Trading Day after the Legend Removal Date until such certificate is delivered without a legend and (ii) if the Company
fails to (a) issue and deliver (or cause to be delivered) to a Purchaser by the Legend Removal Date a certificate representing
the Securities so delivered to the Company by such Purchaser that is free from all restrictive and other legends and (b) if after
the Legend Removal Date such Purchaser purchases (in an open market transaction or otherwise) shares of Common Stock to deliver
in satisfaction of a sale by such Purchaser of all or any portion of the number of shares of Common Stock, or a sale of a number
of shares of Common Stock equal to all or any portion of the number of shares of Common Stock, that such Purchaser anticipated
receiving from the Company without any restrictive legend, then an amount equal to the excess of such Purchaser’s total
purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased
(including brokerage commissions and other out-of-pocket expenses, if any) (the “Buy-In
Price”) over the product of (A) such number of Warrant Shares or Underlying Shares, as applicable, that the Company
was required to deliver to such Purchaser by the Legend Removal Date multiplied by (B) the lowest closing sale price of the Common
Stock on any Trading Day during the period commencing on the date of the delivery by such Purchaser to the Company of the applicable
Warrant Shares or Underlying Shares (as the case may be) and ending on the date of such delivery and payment under this Section
4.1(d).


 


4.2       Furnishing
of Information. (a) Until the earliest of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired,
the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all
reports required to be filed by the Company after the date hereof pursuant to the Exchange Act even if the Company is not then
subject to the reporting requirements of the Exchange Act.


 


(b)       At
any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of
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 (i) shall fail for any reason to satisfy the current public information
requirement under Rule 144(c) or (ii) has ever been an issuer described in Rule 144(i)(1)(i) or becomes an issuer in the future,
and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”)
then, in addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial
liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the Warrant Shares,
an amount in cash equal to two percent (2.0%) of the aggregate Exercise Price of such Purchaser’s Warrants on the day of
a Public Information Failure and on every thirtieth (30th) day (pro rated for periods totaling less than thirty days)
thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time that such public information
is no longer required for the Purchasers to transfer the Warrant Shares pursuant to Rule 144. The payments to which a Purchaser
shall be entitled pursuant to this Section 4.2(b) are referred to herein as “Public Information Failure Payments.”
Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public
Information Failure Payments are incurred and (ii) the third (3rd) Business Day after the event or failure giving rise
to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information Failure Payments
in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial
months) until paid in full. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Public Information
Failure, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief.

4.3       Integration.
The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined
in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require
the registration under the Securities Act of the sale of the Shares, Underlying Shares, Warrants or Warrant Shares or that would
be integrated with the offer or sale of the Securities for purposes of the rules and regulations of any Trading Market such that
it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before
the closing of such subsequent transaction.


 


4.4       Securities
Laws Disclosure; Publicity. The Company shall (a) by 9:00 a.m. (New York City time) on the date hereof, issue a press release
disclosing the material terms of the transactions contemplated hereby, and (b) file a Current Report on Form 8-K, including the
Transaction Documents as exhibits thereto, with the Commission within the time required by the Exchange Act. From and after the
issuance of such press release, the Company represents to the Purchasers that it shall have publicly disclosed all material, non-public
information delivered to any of the Purchasers by the Company or any of its Subsidiaries, or any of their respective officers,
directors, employees or agents in connection with the transactions contemplated by the Transaction Documents. In addition, effective

under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers,
directors, agents, employees or Affiliates on the one hand, and any of the Purchasers or any of their Affiliates on the other
hand, shall terminate. The Company and each Purchaser shall consult with each other in issuing any other press releases with respect
to the transactions contemplated hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise
make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or
without the prior consent of each Purchaser, with respect to any press release of the Company, which consent shall not unreasonably
be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide
the other party with prior notice of such public statement or communication. Notwithstanding the foregoing, the Company shall
not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or any
regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (a) as required by federal securities
law in connection with the filing of final Transaction Documents with the Commission or a filing by the Company with the Commission
as required by Section 4.18 and (b) to the extent such disclosure is required by law or Trading Market regulations, in which case
the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b).


 




    	25



    	 



    

 


4.5       Shareholder
Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that
any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including
any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the
Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving
Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.


 


4.6       Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction
Documents, which shall be disclosed pursuant to Section 4.4, the Company covenants and agrees that neither it, nor any other Person
acting on its behalf will provide any Purchaser or its agents or counsel with any information that constitutes, or the Company
reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have consented to
the receipt of such information and agreed with the Company to keep such information confidential. The Company understands and
confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.
To the extent that the Company delivers any material, non-public information to a Purchaser without such Purchaser’s consent,
the Company hereby covenants and agrees that such Purchaser shall not have any duty of confidentiality to the Company, any of
its Subsidiaries, or any of their respective officers, directors, agents, employees or Affiliates, or a duty to the Company, any
of its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates not to trade on the basis
of, such material, non-public information, provided that the Purchaser shall remain subject to applicable law. To the extent that
any notice provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding
the Company or any Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report
on Form 8-K. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting
transactions in securities of the Company.

or Common Stock Equivalents, (c) for the settlement of any outstanding litigation or (d) in violation of FCPA or OFAC regulations.

4.8       Indemnification
of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold each Purchaser and its directors,
officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of
a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser
(within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser 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 Purchaser
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 the
Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not
an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction Documents (unless
such action is solely based upon a material breach of such Purchaser Party’s representations, warranties or covenants under
the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations
by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party which is finally judicially
determined to constitute fraud, gross negligence or willful misconduct) or (c) in connection with any registration statement of
the Company providing for the resale by the Purchasers of the Underlying Shares or Warrant Shares issued and issuable upon conversion
of the Shares or exercise of the Warrants, the Company will indemnify each Purchaser Party, to the fullest extent permitted by
applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable
attorneys’ fees) and expenses, as incurred, arising out of or relating to (i) any untrue or alleged untrue statement of
a material fact contained in such registration statement, any prospectus or any form of prospectus or in any amendment or supplement
thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of any prospectus or supplement thereto,
in the light of the circumstances under which they were made) not misleading, except to the extent, but only to the extent, that
such untrue statements or omissions are based solely upon information regarding such Purchaser furnished in writing to the Company
by such Purchaser expressly for use therein, or (ii) any violation or alleged violation by the Company of the Securities Act,
the Exchange Act or any state securities law, or any rule or regulation thereunder in connection therewith. If any action shall
be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser
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 reasonably acceptable to the Purchaser Party. Any Purchaser 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 Purchaser Party except to the extent that (x) the employment thereof has been specifically authorized by the Company in
writing, (y) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (z) in such
action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company
and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses
of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (1) for
any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably
withheld or delayed; or (2) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any
Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party
in this Agreement or in the other Transaction Documents. The indemnification required by this Section 4.8 shall be made by periodic
payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred.
The indemnity agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party
against the Company or others and any liabilities the Company may be subject to pursuant to law.


 




    	27



    	 



    

 


4.9       Reservation
of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available
at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company
to issue the Underlying Shares and Warrant Shares.


 


4.10       Listing
of Common Stock. The Company hereby agrees to use commercially reasonable best efforts to maintain the listing or quotation
of the Common Stock on the Trading Market on which it is currently listed, and concurrently with the Closing, the Company shall
apply to list or quote all of the Underlying Shares and Warrant Shares on such Trading Market and promptly secure the listing
of all of the Underlying Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company applies
to have the Common Stock traded on any other Trading Market, it will then include in such application all of the Underlying Shares
and Warrant Shares, and will take such other action as is necessary to cause all of the Underlying Shares and Warrant Shares to
be listed or quoted on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary
to continue the listing and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s
reporting, filing and other obligations under the bylaws or rules of the Trading Market. The Company agrees to maintain the eligibility
of the Common Stock for electronic transfer through the Depository Trust Company or another established clearing corporation,
including, without limitation, by timely payment of fees to the Depository Trust Company or such other established clearing corporation
in connection with such electronic transfer.


 


4.11       Participation
Right. From the date hereof until one (1) year after the Closing Date, neither the Company nor any of its Subsidiaries shall,
directly or indirectly, issue, offer, sell, grant any option or right to purchase, or otherwise dispose of (or announce any issuance,
offer, sale, grant of any option or right to purchase or other disposition of) any equity security or any equity-linked or related
security, any Common Stock Equivalents, any preferred stock or any purchase rights) (any such issuance, offer, sale, grant, disposition
or announcement is referred to as a “Subsequent Placement”), unless the Company shall have first complied with
this Section 4.11. The Company acknowledges and agrees that the right set forth in this Section 4.11 is a right granted by the
Company, separately, to each Purchaser; provided however that this entire Participation Right Section 4.11 shall not apply to
any Variable Rate Transaction with Lincoln Park Capital Fund, LLC or it’s affiliates (“LPC”).


 


(a)       Prior
to any proposed or intended Subsequent Placement, the Company shall deliver to each Purchaser a written notice of its proposal
or intention to effect a Subsequent Placement (each such notice, a “Pre-Notice”), which Pre-Notice shall not
contain any information (including, without limitation, material, non-public information) other than: (A) a statement that the
Company proposes or intends to effect a Subsequent Placement, (B) a statement that the statement in clause (A) above does not
constitute material, non-public information and (iii) a statement informing such Purchaser that it is entitled to receive an Offer
Notice (as defined below) with respect to such Subsequent Placement upon its written request. Upon the written request of a Purchaser
within one (1) Trading Day after the Company’s delivery to such Purchaser of such Pre-Notice, and only upon a written request
by such Purchaser, the Company shall promptly deliver to such Purchaser an irrevocable written notice (the “Offer Notice”)
of any proposed or intended issuance or sale or exchange (the “Offer”) of the securities being offered (the
“Offered Securities”) in a Subsequent Placement, which Offer Notice shall (1) identify and describe the Offered
Securities, (2) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount
of the Offered Securities to be issued, sold or exchanged, (3) identify the Persons (if known) to which or with which the Offered
Securities are to be offered, issued, sold or exchanged and (4) offer to issue and sell to or exchange with such Purchaser in
accordance with the terms of the Offer twenty percent (20%) of the Offered Securities, (the “Basic Amount”),
and (b) with respect to each Purchaser that elects to purchase its Basic Amount, any additional portion of the Offered Securities
attributable to the Basic Amounts of other Purchasers as such Purchaser shall indicate it will purchase or acquire should the
other Purchasers subscribe for less than their Basic Amounts (the “Undersubscription Amount”).


 




    	28



    	 



    

 


(b)       To
accept an Offer, in whole or in part, such Purchaser must deliver a written notice to the Company prior to the end of the third
(3rd) Trading Day after such Purchaser’s receipt of the Offer Notice (the “Offer Period”), setting forth
the portion of such Purchaser’s Basic Amount that such Purchaser elects to purchase and, if such Purchaser shall elect to
purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Purchaser elects to purchase (in either case,
the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Purchasers are less than the total
of all of the Basic Amounts, then such Purchaser who has set forth an Undersubscription Amount in its Notice of Acceptance shall
be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for;
provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts
and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), such Purchasers who has subscribed
for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as
the Basic Amount of such Purchaser bears to the total Basic Amounts of all Purchasers that have subscribed for Undersubscription
Amounts, subject to rounding by the Company to the extent it deems reasonably necessary. Notwithstanding the foregoing, if the
Company desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company
may deliver to each Purchaser a new Offer Notice and the Offer Period shall expire on the third (3rd) Trading Day after such Purchaser’s
receipt of such new Offer Notice.


 


(c)       The
Company shall have five (5) days from the expiration of the Offer Period above (A) to offer, issue, sell or exchange all or any
part of such Offered Securities as to which a Notice of Acceptance has not been given by a Purchaser (the “Refused Securities”)
pursuant to a definitive agreement(s) (the “Subsequent Placement Agreement”), but only to the offerees described
in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and
interest rates) that are not more favorable to the acquiring Person or Persons or less favorable to the Company than those set
forth in the Offer Notice and (B) to publicly announce (1) the execution of such Subsequent Placement Agreement, and (2) either
(a) the consummation of the transactions contemplated by such Subsequent Placement Agreement or (b) the termination of such Subsequent
Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement
and any documents contemplated therein filed as exhibits thereto.


 




    	29



    	 



    

 


(d)       In
the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the
terms specified in Section 4.11(c) above), then such Purchaser may, at its sole option and in its sole discretion, reduce the
number or amount of the Offered Securities specified in its Notice of Acceptance on a pro rata basis based on the revised
number or amount of Offered Securities as compared to the original number or amount of the Offered Securities. In the event that
any Purchaser so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company
may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities
have again been offered to the Purchasers in accordance with Section 4.11(a) above.


 


(e)       Upon
the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Purchaser shall acquire
from the Company, and the Company shall issue to such Purchaser, the number or amount of Offered Securities specified in its Notice
of Acceptance. The purchase by such Purchaser of any Offered Securities is subject in all cases to the preparation, execution
and delivery by the Company and such Purchaser of a separate purchase agreement relating to such Offered Securities reasonably
satisfactory in form and substance to such Purchaser and its counsel. The Company and each Purchaser agree that if any Purchaser
elects to participate in the Offer, neither the Subsequent Placement Agreement with respect to such Offer nor any other transaction
documents related thereto (collectively, the “Subsequent Placement Documents”) shall include any term or provision
whereby such Purchaser shall be required to agree to any restrictions on trading as to any securities of the Company or be required
to consent to any amendment to or termination of, or grant any waiver, release or the like under or in connection with, any agreement
previously entered into with the Company or any instrument received from the Company.


 


(f)       Notwithstanding
anything to the contrary in this Section 4.11 and unless otherwise agreed to by such Purchaser, the Company shall either confirm
in writing to such Purchaser that the transaction with respect to the Subsequent Placement has been abandoned or shall publicly
disclose its intention to issue the Offered Securities, in either case in such a manner such that such Purchaser will not be in
possession of any material, non-public information, by the fifth (5th) Trading Day following delivery of the Offer Notice. If
by such fifth (5th) Trading Day, no public disclosure regarding a transaction with respect to the Offered Securities has been
made, and no notice regarding the abandonment of such transaction has been received by such Purchaser, such transaction shall
be deemed to have been abandoned and such Purchaser shall not be in possession of any material, non-public information with respect
to the Company or any of its Subsidiaries.


 


(g)       The
Company shall not be permitted to deliver more than one Offer Notice to any Purchaser in any sixty (60) day period, except as
expressly contemplated by the last sentence of Section 4.11(b).


 


(h)       Any
Offered Securities not acquired by a Purchaser or other Persons in accordance with this Section 4.11 may not be issued, sold or
exchanged until they are again offered to such Purchaser under the procedures specified in this Agreement. The restrictions contained
in this Section 4.11 shall not apply in connection with the issuance of any Exempt Issuances.

4.12       Variable
Rate Transactions. From the date hereof until 4 years following the Closing Date, the Company shall be prohibited from effecting
or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock
Equivalents (or a combination of units thereof) involving a Variable Rate Transaction; provided that nothing herein shall prohibit
the Company from entering into a Variable Rate Transaction with LPC. “Variable Rate Transaction” means a transaction
in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable
for, or include the right to receive additional shares of Common Stock either (A) at a conversion price, exercise price or exchange
rate or other price that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at
any time after the initial issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that
is subject to being reset at some future date after the initial issuance of such debt or equity security or upon the occurrence
of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock
or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit, whereby
the Company may issue securities at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against
the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages.


 


4.13       Equal
Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or paid
to any Person to amend or consent to a waiver or modification of any provision of the Transaction Documents unless the same consideration
is also offered to all of the parties to the Transaction Documents. For clarification purposes, this provision constitutes a separate
right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to
treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect
to the purchase, disposition or voting of Securities or otherwise.


 


4.14       Certain
Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither
it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including
Short Sales of any of the Company’s securities during the period commencing with the execution of this Agreement and ending
at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release
as described in Section 4.4. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time
as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release
as described in Section 4.4, such Purchaser will maintain the confidentiality of the existence and terms of this transaction and
the information included in the Disclosure Schedules. Notwithstanding the foregoing and notwithstanding anything contained in
this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any representation,
warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company after the time
that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described
in Section 4.4, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of the Company
in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are
first publicly announced pursuant to the initial press release as described in Section 4.4 and (iii) no Purchaser shall have any
duty of confidentiality or duty not to trade in the securities of the Company to the Company or its Subsidiaries after the issuance
of the initial press release as described in Section 4.4. 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 covenant 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.

4.15       [RESERVED]


 


4.16       Exercise
Procedures. The form of Notice of Conversion included in the Certificate of Designation or the Notice of Exercise included
in the Warrants set forth the totality of the procedures required of the Purchasers in order to convert the Shares or exercise
the Warrants. No additional legal opinion, other information or instructions shall be required of the Purchasers to convert the
Shares or exercise their Warrants. Without limiting the preceding sentences, no ink-original Notice of Conversion or Notice of
Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Conversion
or Notice of Exercise form be required in order to convert the Shares or exercise the Warrants. The Company shall honor conversions
of the Shares and exercises of the Warrants, and shall deliver the Underlying Shares or Warrant Shares in accordance with the
terms, conditions and time periods set forth in the Transaction Documents.


 


4.17       Form
D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Shares, Underlying Shares, Warrants and
Warrant Shares as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company
shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify
the Shares, Underlying Shares, Warrant and Warrant Shares for, sale to the Purchasers at the Closing under applicable securities
or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request
of any Purchaser.


 


4.18       Registration
Statement. As soon as practicable (and in any event by the 30th calendar day following the Closing Date), the Company shall
file a registration statement on Form S-1 (or other appropriate form) providing for the resale by the Purchasers of the Underlying
Shares or Warrant Shares issued and issuable upon conversion of the Shares or exercise of the Warrants. The Company shall use
its best efforts to cause such registration to become effective within 90 days following the Closing Date and to keep such registration
statement effective at all times until no Purchaser owns any Shares, Underlying Shares, Warrants or Warrant Shares. In addition
to such Purchaser’s other available remedies, if the Company fails to file the registration statement referenced in the
prior sentence within the required period of time, the Company shall pay to a Purchaser, in cash, as partial liquidated damages
and not as a penalty, $10 for each $1,000 invested under this Agreement per Trading Day that such failure continues. In addition
to such Purchaser’s other available remedies, if the Company fails to have the registration statement referenced in the
prior sentence declared effective within 90 days of the date of this Agreement, the Company shall pay to a Purchaser, in cash,
as partial liquidated damages and not as a penalty, $10 for each $1,000 invested under this Agreement per Trading Day that such
failure continues.

MISCELLANEOUS


 


5.1       Termination.
This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect
whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the Closing
has not been consummated on or before April 9, 2018; provided, however, that no such termination will affect the right of any
party to sue for any breach by any other party (or parties).


 


5.2       Fees
and Expenses. Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay the fees and
expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident
to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all Transfer Agent
fees (including, without limitation, any fees required for same-day processing of any instruction letter delivered by the Company
and any exercise notice delivered by a Purchaser), stamp taxes and other taxes and duties levied in connection with the delivery
of any Securities to the Purchasers.


 


5.3       Entire
Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of
the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral
or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.


 


5.4       Notices.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and
shall be deemed given and effective on the earliest of: (a) the date of transmission, if such notice or communication is delivered
via facsimile at the facsimile number or email attachment at the email address as set forth on the signature pages attached hereto
at or prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such
notice or communication is delivered via facsimile at the facsimile number or email attachment at the email address as set forth
on the signature pages attached hereto on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any
Trading Day, (c) the second (2nd) Trading Day following the date of mailing, if sent by U.S. nationally recognized
overnight courier service or (d) upon actual receipt by the party to whom such notice is required to be given. The address for
such notices and communications shall be as set forth on the signature pages attached hereto. To the extent that any notice provided
pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding the Company or any Subsidiaries,
the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form 8-K.


 




    	33



    	 



    

 


5.5       Amendments;
Waivers. No provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed,
in the case of an amendment, by the Company and Purchasers which purchased at least 51% in interest of the Shares based on the
initial Subscription Amounts hereunder or, in the case of a waiver, by the party against whom enforcement of any such waived provision
is sought, provided that if any amendment, modification or waiver disproportionately and adversely impacts a Purchaser (or group
of Purchasers), the consent of such disproportionately impacted Purchaser (or group of Purchasers) shall also be required. No
waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing
waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof,
nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.
Any proposed amendment or waiver that disproportionately, materially and adversely affects the rights and obligations of any Purchaser
relative to the comparable rights and obligations of the other Purchasers shall require the prior written consent of such adversely
affected Purchaser. Any amendment effected in accordance with this Section 5.5 shall be binding upon each Purchaser and holder
of Securities and the Company.


 


5.6       Headings.
The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.


 


5.7       Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted
assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of
each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to
whom such Purchaser assigns or transfers any Securities, provided that such transferee agrees in writing to be bound, with respect
to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”


 


5.8       No
Third-Party Beneficiaries. The Placement Agent shall be the third party beneficiary of the representations and warranties
of the Company in Section 3.1 and the representations and warranties of the Purchasers in Section 3.2. This Agreement is intended
for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor
may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.8 and this Section 5.8.


 


5.9       Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all legal Proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a
party hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be
commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to
the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication
of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including
with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert
in any Action or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such Action
or Proceeding is improper or is an inconvenient venue for such Proceeding. Each party hereby irrevocably waives personal service
of process and consents to process being served in any such Action or Proceeding by mailing a copy thereof via registered or certified
mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If any party shall commence
an Action or Proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company
under Section 4.8, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Action
or Proceeding.


 




    	34



    	 



    

 


5.10       Survival.
The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.


 


5.11       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.


 


5.12       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.


 


5.13       Rescission
and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of)
any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction
Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser
may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand
or election in whole or in part without prejudice to its future actions and rights; provided, however, that in the case of a rescission
of an exercise of a Warrant, the applicable Purchaser shall be required to return any shares of Common Stock subject to any such
rescinded exercise notice concurrently with the return to such Purchaser of the aggregate exercise price paid to the Company for
such shares and the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant
(including, issuance of a replacement warrant certificate evidencing such restored right).


 




    	35



    	 



    

 


5.14       Replacement
of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation),
or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory
to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances
shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement
Securities.


 


5.15       Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of
the Purchasers 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.


 


5.16       Payment
Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document
or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from,
disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person
under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived
and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.


 


5.17       Independent
Nature of Purchasers’ Obligations and Rights. The obligations of each 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. For reasons of administrative convenience only, each
Purchaser and its respective counsel have chosen to communicate with the Company through Schiff Hardin. Schiff Hardin does not
represent any of the Purchasers and only represents the Placement Agent. 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.


 




    	36



    	 



    

 


5.18       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.


 


5.19Saturdays,
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.


 


5.20       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.


 


5.21       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.
